Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail transit, and in particular to a torsion spring mounting structure for rail transit. Background Technology
[0002] Torsion spring installation tools can improve efficiency and working conditions, and are mainly used in the assembly of rail transit door systems.
[0003] However, existing torsion spring installation often uses conventional tools. Due to the large torque of the torsion spring, assembly is very difficult, and the torsion spring is prone to disengagement during installation, which can lead to operator safety accidents and damage to the product.
[0004] Therefore, it is necessary to develop a torsion spring mounting structure specifically for rail transit to overcome the above problems. Utility Model Content
[0005] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, this utility model provides a torsion spring installation structure for rail transit, which facilitates the installation of torsion springs for rail transit, reduces assembly difficulty, and solves the problems of high labor intensity, easy safety accidents and product damage during torsion spring installation.
[0006] Technical solution: This utility model provides a torsion spring installation structure for rail transit, comprising a torsion spring and a sleeve, characterized in that: it includes a fixed base, a torsion sleeve, and a handle connected in sequence; the torsion sleeve is connected to a thin nut via a pin; the sleeve passes through the torsion spring, and the torsion spring is located between the fixed base and the torsion sleeve.
[0007] The fixed base is a detachable structure and is located on the platform of the rail transit system.
[0008] The torsion sleeve has stops on both sides for controlling the rotation angle and preventing the handle from springing back.
[0009] The support foot at one end of the torsion spring is located inside the slot of the fixed base.
[0010] The supporting leg at the other end of the torsion spring is secured by the fixing clip of the torsion sleeve.
[0011] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention facilitates the installation of torsion springs for rail transit, reduces assembly difficulty, and solves the problems of high labor intensity, easy safety accidents and product damage during torsion spring installation; through the new torsion spring installation structure, it replaces the existing assembly tools, further improving production efficiency.

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0016] This utility model discloses a torsion spring mounting structure for rail transit, comprising a fixed base 1, a torsion sleeve 4, and a handle 5 connected in sequence; the torsion sleeve 4 is connected to a thin nut 7 via a pin 6; a sleeve 3 passes through the torsion spring 2, which is located between the fixed base 1 and the torsion sleeve 4. The fixed base 1 is a detachable structure and can be placed on any platform of the rail transit without restriction. The torsion sleeve 4 has stops on both sides for controlling the rotation angle and preventing the handle from rebounding, allowing the torsion sleeve 4 and handle 5 to easily open the torsion spring 2. One end of the torsion spring 2 has a support foot located in the groove of the fixed base 1. The other end of the torsion spring 2 is secured by a fixing clip on the torsion sleeve 4. The pin 6 and the double thin nuts 7 ensure that the device rotates freely and will not fall off.
[0017] In use, the torsion spring 2 is manually placed into the fixed base 1, and the support foot of one end of the torsion spring 2 is fixed in the slot of the fixed base 1; the fixing clip of the torsion sleeve 4 is used to lock the support foot of the other end of the torsion spring 2; the handle 5 is turned to drive the torsion sleeve 4 to open the support foot of the torsion spring 2; the sleeve 3 is inserted along the middle of the device, the torsion spring mounting hole of the sleeve 3 is aligned with the opened support foot of the torsion spring 2, the handle 5 is released, the torsion spring 2 is installed into the sleeve 3, and the assembly is completed.
[0018] Through practical application, the torsion spring installation structure of this utility model for rail transit has effectively reduced labor intensity, improved production efficiency, and prevented products from being easily damaged.
