Problems solved by technology

[0003] 1. When the mosquito net lands, the lifting rope is pulled out of the reel by the self-weight traction of the tent body. If any one or more lifting ropes lose the traction of the self-weight of the tent body, this situation is more likely to occur in a certain part of the tent body. The part is supported and hooked by the bed or other items and cannot be landed, especially because the connection between the lifting rope and the tent body is separated due to children playing and washing, so that the lifting ropes cannot be pulled out of the reel synchronously. In this way, it is easier to cause the lifting rope that loses traction to loosen and come out of the drum or be rewound back to the drum, so that the lifting ropes will be entangled with each other like a mess or entangled with the drum and lose the correct connection with the drum. The lifting mechanism cannot work normally, and it is difficult to untie and repair. This kind of failure is called "rope chaos" failure.
[0004] 2. The lifting speed and stroke of all lifting ropes in the background technology are synchronous, and the connecting points of the lifting rope and the tent must be at the same height to make the raised tent reach the top dead center at the same time, otherwise the tent will rise. The unevenness of each part will affect the appearance. From the actual use of the produ

Embodiment 1

[0030] Such as figure 2 As shown, the drive device of the present embodiment is a human drive device composed of pulley 5, pulley 6, bead chain rope 7 and sprocket wheel 8 matched therewith;

[0031] Such as figure 1 , figure 2 , image 3 , image 3 .1 and image 3 As shown in .2, the driving gear 9 is connected with the sprocket 8, and the driving gear 9 passes through the transmission tooth 21 in the pit of the bottom surface of the counter driving gear 10 and the annular tooth surface positioned on the top surface of the counter driving gear 10. The formed one-way transmission device is connected with the reverse driving gear 10; the periphery of the driving gear 9 and the reverse driving gear 10 is connected with tractors equal to the number of traction points necessary for the tent body 1 (the appearance is that the housing 12 and the hoisting rope 3, image 3 Only the internal structure of a tractor is drawn in the middle), and the lower end of the hoisting rope ...

Embodiment 2

[0037] As shown in Fig. 4, Fig. 4.1, Fig. 4.2 and Fig. 4.3, the driving device of the present embodiment is a motor 32, and the periphery of the driving gear 9 is connected with tractors equal to the number of traction points necessary for the tent body 1 (the appearance is a shell Body 12 and lifting rope 3, only draw the assembly figure of a tractor among the figure), the lower end of the lifting rope 3 of each tractor passes through a lifting pulley 4 and guides down and links with a traction point of tent body 1;

[0038] The overload separation device of this embodiment is composed of an internal gear 22, a central shaft 11, a fixed screw rod 24, a slider 23, a top column 26, a pressure spring 27, a bolt wheel 28, a bolt pin 29, a steel ball 30, and a pressure spring 31;

[0039] The brake device of this embodiment is composed of an inner gear ring 33, a brake gear ring 35, and a brake tooth 34;

[0040] The passive gear 13 is hollow, and the inner circumference is fixedl...

Embodiment 3

[0045] Such as Figure 5 As shown, the drive device of the present embodiment is a human-powered drive device composed of a drag cable 36, a drive wheel 37b, and a drive wheel 37. One end of the drag cable 36 is connected in a groove of the drive wheel 37 and wound into the groove 3 to 5 Meter, the other end is connected in the groove of driving wheel 37b;

[0046] Drive gear 9 is sequentially connected with drive wheel 37b, and drive wheel 37 is then passed through the one-way transmission formed by the drive tooth 21 in the pit of the bottom surface of drive wheel 37b and the annular tooth surface on the top surface of reverse drive gear 10. The device is connected with the reverse driving gear 10;

Abstract

The mosquito net elevator includes a driver, a driving gear and elevating pulleys in the same number as the drawing points. It features that around the driving gear there are drawing units in the same number as the drawing points. Each drawing unit consists of one casing, one middle shaft, one driven gear, one reel and one piece of elevating rope. It also features that between the driven gear and the reel in each drawing unit there is an overload separator and one brake. The elevator is superior in that each drawing unit is used to draw a piece of rope and thus there is no twisting failure and that the elevator elevates the net in balanced and regular mode.

Description

technical field [0001] The invention relates to a lifting mechanism for lifting and lowering mosquito nets. Background technique [0002] Existing known lifting mosquito net has a variety, more representative has: No. 96245927.5 patent, No. 91230333.6 patent, No. 88100560.6 patent, the lifting mechanism of these lifting mosquito nets all is to concentrate all hoisting ropes into one called " cable wheel " Perhaps the reel of " wire winding dish " is rolled in and released and realizes the lifting of mosquito net, makes it to have following shortcoming: [0003] 1. When the mosquito net lands, the lifting rope is pulled out of the reel by the self-weight traction of the tent body. If any one or more lifting ropes lose the traction of the self-weight of the tent body, this situation is more likely to occur in a certain part of the tent body. The part is supported and hooked by the bed or other items and cannot be landed, especially because the connection between the lifting r...
