Problems solved by technology

Since the hydraulic transmission needs to be equipped with a small hydraulic station, the hydraulic system needs to be maintained frequently, and the cost is relatively high, so it is rarely used in actual use; and the guide rod of the gas spring will be eccentrically worn during long-term use. , and the seal is greatly affected by the ambient temperature, which will cause the seal to fail after a period of use, causing the gas spring to leak gas, causing the gas spring to fail to open and close, or even fail to work

Embodiment Construction

[0008] Such as figure 1 and figure 2 As shown in the figure, it is a hand-locked support rod with an upturned door. The support 1 is connected to the sliding cylinder 3 through the lower pin shaft 2. The locking claw 4 and the sliding cylinder 3 are fixed as a whole. The manual locking nut on the locking claw 4 5 is connected with it, the slide bar 6 is installed in the slide tube 3, the end of the slide bar 6 in the slide tube 3 has a positioning groove, and the upper pin shaft 7 is connected with the slide bar 6. The locking pawl 4 is composed of four locking pieces with gaps between them.

[0009] The working principle of the present invention is as follows: bearing 1 is fixed on the door frame of the upward turning door, and the upper bearing pin 7 connects the slide bar 6 with the upward turning door.

[0010] When it is necessary to open the upper flap door, the hinges at the lower pin shaft 2 and the upper pin shaft 7 will make the upper flap door support rod automat...

Abstract

The invention discloses a hand-locking type support rod of a tip-up door. A support is connected with a sliding cylinder through a lower hinge pin; a locking jaw is integrally fixed with the sliding cylinder; a hand locking nut on the locking jaw is connected with the locking jaw; a sliding rod is mounted in the sliding cylinder; a positioning groove is arranged at the tail end of the sliding rod in the sliding cylinder; and an upper hinge pin is connected with the sliding rod. The hand-locking type support rod of a tip-up door provided by the invention adopts a full-mechanical structure, is manually operated and saves all pneumatic and hydraulic elements; as the locking jaw is made from a hard material, the concentricity between the sliding rod and the sliding cylinder is ensured, eccentric wear between the sliding rod and a guide cylinder is reduced to a great degree, the service life of the easily-damaged parts is prolonged, and the failure of the support rod caused by a sealing element is eliminated; and moreover, the hand-locking type support rod has the characteristics of light weight, low cost, good shape and the like, and is convenient to install and adjust and to replace the components.

Description

technical field [0001] The invention relates to a manual locking support mechanism for an upward-turning door, in particular to a hand-lock support rod for an upward-turning door suitable for large skid-mounted equipment. Background technique [0002] In the current support mechanism for turning up the door, it is generally realized by using a gas spring or a small hydraulic cylinder. Since the hydraulic transmission needs to be equipped with a small hydraulic station, the hydraulic system needs to be maintained frequently, and the cost is relatively high, so it is rarely used in actual use; and the guide rod of the gas spring will be eccentrically worn during long-term use. , and the seal is greatly affected by the ambient temperature, which will cause the seal to fail after a period of use, causing the gas spring to leak gas, causing the gas spring to fail to open and close, or even fail to work. Contents of the invention [0003] The object of the present invention is ...
