The invention discloses a flatcar sewing machine provided with a lifting machine head. The machine comprises a machine table, a flatcar sewing machine body arranged on the machine table as well as a flatcar sewing machine head connected with the flatcar sewing machine body through a lifting mechanism, wherein the flatcar sewing machine head perpendicularly moves up and down relative to the flatcar sewing machine body under the control of the lifting mechanism, so that a knitting mechanism in the flatcar sewing machine head and a transmission mechanism in the flatcar sewing machine body are in a separated state or a linked state. When the flatcar sewing machine stops working, the machine head is upwards lifted, so that large space is reserved between a machine needle and a table surface, sufficient space is provided for treatment of fabric on the table surface in the working process of an operator, the problem that the fabric is snagged and the machine needle is even broken due to the fact that the machine needle easily hooks the fabric because of too small distance between the machine needle and the table surface is solved, and the working efficiency of the operator is effectively improved. Besides, the flatcar sewing machine provided with the lifting machine head is simple in structure, occupies small space, is low in manufacturing cost and is suitable for wide application.

The invention provides a direct type LED backlight module, which comprises a back plate, a diffusion plate and a rubber frame, and is characterized in that: the opening end of the back plate is provided with a supporting platform; the rubber frame is arranged at the periphery of the supporting platform and fixed on the supporting platform; the diffusion plate is arranged on the supporting platform and fixed by the rubber frame; and the diffusion plate is supported by adjusting an area of a contact area between the diffusion plate and the supporting platform on the back plate and/or adhering the diffusion plate to the supporting platform. The invention also provides a television comprising the backlight module. By the backlight module and the television, problems that the volume of a bracket is increased, the bracket generates a shade in the backlight module and an optical diaphragm is arranged because the light mixing distance is increased are effectively avoided, and the cost of the whole television is obviously reduced.

The invention relates to a front and rear longitudinal beam welding device for an automobile and a welding method thereof. The front and rear longitudinal beam welding device includes a solder sheet positioning device and a weld seam control device. The solder sheet positioning device comprises a positioning platform, a first placement groove and a second placement groove, and the weld seam control device is disposed on the positioning platform; a first solder sheet is placed in the first placement groove, and the second solder sheet is placed in the second placement groove; the left side of the first solder sheet is provided with a first positioning rod for abutting against the first solder sheet, and the right side of the second solder sheet is provided with a second positioning rod forabutting against the second solder sheet. The weld seam control device comprises a plurality of pressure wheels located at the center of the end of a workpiece to be welded, a plurality of motors connected with the pressure wheels are arranged on both sides of the workpiece to be welded, and a sensor is arranged at the weld joint of the workpiece to be welded. The front and rear longitudinal beamwelding device has the advantages that two material sheets to be welded are reinforced and positioned from the left side and the right side respectively, thereby reducing the welding burden over workers and ensuring the smooth progress of the laser welding.

The invention relates to an integrated end cover for a polypropylene film capacitor. The integrated end cover comprises a copper foil outgoing line, an explosion-proof block, a cover plate, an insulating bowl and a leading-out end, wherein the leading-out end is mounted in a center hole of the insulating bowl through a rivet and then is mounted in a corresponding stamping hole in the cover plate;the copper foil outgoing line is fixed by being inserted in a corresponding bayonet of the explosion-proof block; the leading-out end, the insulating bowl, the cover plate, the explosion-proof block and the copper foil outgoing line are fixed through stamping rivets and are connected into a whole, namely, the end cover of the capacitor; the copper foil outgoing line wraps the copper foil outgoingline in an insulating mode for insulating protection; the end cover is welded on the end surface of a capacitor element through the copper foil outgoing line; and the end cover is connected with the capacitor element by taking the copper foil outgoing line as a medium. According to the integrated end cover, the bad phenomena of thermal breakdown and the like of the capacitor can be reduced, so that the reliability of the long-term service life of the polypropylene film capacitor is improved; and moreover, the heat dissipation performance is better, and the temperature resistance is more excellent.

The present invention provides a seat-type massage machine, which can minimize the space required for bending the compressed air hose even when the seat is swinging, and can provide ample space for the layout of other components located under the seat. In addition, the operation of the solenoid valve can always be maintained normally regardless of the swing of the seat portion. The seat type massage machine is equipped with: an air pump (51) for supplying air to the air bags (28, 48) and a plurality of electromagnetic valves (55) arranged in the piping connecting the air pumps and the air bags, and the solenoid valve pairs will be pumped by the air. The supplied air is supplied to the air bag or the air in the air bag is discharged, and a plurality of electromagnetic valves (55) are arranged on the bracket (56), and the bracket (56) is installed on a swinging body with the seat (20). Install on the frame (21). In addition, the reciprocating direction of the plunger of each electromagnetic valve (55) is parallel to the horizontal axis (16) of the support seat (20).

The invention discloses a machine room air conditioner low-temperature starting control method, device and equipment and a storage medium, and relates to the technical field of air conditioner refrigeration. The method comprises the steps that when the collected compressor suction pressure is not smaller than the liquid storage tank pressure, a heater arranged on a liquid storage tank is started, and according to the size relation between the liquid storage tank pressure and the compressor suction pressure, the heater is started; performing return difference adjustment on the heating power of the heater; when the pressure of the heated liquid storage tank is higher than the suction pressure of the compressor, starting the machine room air conditioner, continuously starting the heater, and keeping the pressure of the liquid storage tank higher than the suction pressure of the compressor; dynamically controlling the opening degree of the electronic expansion valve based on the set suction superheat degree; when the pressure of the condenser is higher than that of the liquid storage tank, the heater is closed, and the machine room air conditioner enters a normal operation mode. Normal starting and operation of the machine room air conditioner in the low-temperature environment can be guaranteed.
