Description

Technical Field

[0001] This utility model relates to the field of elevator buffers, and in particular to an elevator buffer adjusting rod. Background Technology

[0002] Elevator buffers are the core components of elevator safety systems. They are used to absorb kinetic energy when an elevator loses control and crashes to the bottom or top, protecting the safety of passengers and equipment. The adjusting rod of the elevator buffer is mainly used to adjust the compression stroke and reset performance of the buffer, ensuring that the elevator can effectively absorb impact energy when it overspeeds or loses control.

[0003] Common elevator buffer adjusting rods are threaded rods. By rotating the threaded rod, the pressure of the internal spring or the position of the hydraulic cylinder can be changed. After adjustment, the nut on the adjusting rod is rotated, and the adjusting rod is locked by the squeezing action of the nut. However, rotating the nut usually requires the use of tools, which is inconvenient. In addition, the nut is prone to loosening due to external vibration, making it difficult to lock the adjusting rod and reducing safety and stability. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an elevator buffer adjusting rod, comprising an adjusting rod body;

[0006] A locking mechanism is provided on the adjusting rod body, and the locking mechanism is used to limit and fix the adjusting rod body;

[0007] A positioning mechanism is provided on the locking mechanism, and the positioning mechanism is used to fix the locking mechanism.

[0008] Preferably, the locking mechanism includes:

[0009] A ratchet, which is fixedly connected to one end of the adjusting rod body;

[0010] A limiting block is provided above the ratchet, and the bottom of the limiting block is inserted between adjacent teeth of the ratchet.

[0011] A fixed shaft is fixedly connected to the top of the limiting block;

[0012] A fixed base is provided above the limiting block, and the bottom of the fixed base is rotatably interlocked with both ends of the fixed shaft.

[0013] Preferably, the locking mechanism further includes:

[0016] A tension spring, one end of which is fixedly connected to a connecting block, and the other end of which is fixedly installed to the lower surface of a fixing block.

[0017] Preferably, the positioning mechanism includes:

[0018] A positioning hole is provided at one end of the fixed shaft, and the positioning hole is a square groove.

[0024] The technical effects and advantages of this utility model are as follows:

[0025] This invention utilizes a ratchet, a limiting block, a tension spring, a fixed shaft, a positioning hole, a screw, and a positioning block in a coordinated configuration. When the adjusting rod body drives the ratchet to rotate counterclockwise, the ratchet teeth press against the bottom of the limiting block, pushing the limiting block to rotate clockwise around the fixed shaft. This causes the connecting block to stretch the tension spring, and the elasticity of the tension spring pulls the limiting block to rotate back, so that the bottom of the limiting block engages between adjacent ratchet teeth, providing unidirectional limiting of the ratchet and ensuring unidirectional adjustment of the adjusting rod body, thus improving the stability and safety of the adjustment. Furthermore, by rotating the screw, one end of the positioning block slides into the inner cavity of the positioning hole, limiting the fixed shaft and preventing the fixed shaft and the limiting block from rotating, ensuring the stability of the adjusting rod body and facilitating locking of the adjusting rod body.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figures 1-4 The elevator buffer adjusting rod shown includes an adjusting rod body 1 with external threads, which changes the internal spring pressure or cylinder position of the buffer by rotating the adjusting rod body 1; a locking mechanism 2, which is mounted on the adjusting rod body 1 and is used to limit and fix the adjusting rod body 1, ensuring stability during adjustment and facilitating reset; and a positioning mechanism 3, which is mounted on the locking mechanism 2 and is used to fix the locking mechanism 2, limiting its movement and improving stability and safety.

[0033] Furthermore, the locking mechanism 2 includes a ratchet 21, which is fixedly connected to one end of the adjusting rod body 1. The ratchet 21 rotates together with the adjusting rod body 1, and is used to unidirectionally limit the rotation of the adjusting rod body 1. A limiting block 22 is disposed above the ratchet 21, with its bottom inserted between adjacent teeth of the ratchet 21. The limiting block 22 is used to unidirectionally limit the ratchet 21. When the adjusting rod body 1 rotates counterclockwise, the teeth of the ratchet 21 engage with the bottom of the limiting block 22. The pressure is applied, pushing the limiting block 22 to rotate. When the adjusting rod body 1 rotates clockwise, the bottom of the limiting block 22 blocks the ratchet 21, preventing it from rotating, thus achieving unidirectional adjustment of the adjusting rod body 1. A fixed shaft 23 is fixedly connected to the top of the limiting block 22. The top of the limiting block 22 is rotatably connected to the bottom of the fixed seat 24 via the fixed shaft 23, allowing the limiting block 22 to rotate around the fixed shaft 23. A fixed seat 24 is positioned above the limiting block 22, and the bottom of the fixed seat 24... The fixed base 24 is rotatably inserted at both ends of the fixed shaft 23, and its bottom is U-shaped. A fixed block 25 is fixedly connected to the upper surface of the fixed base 24 via its lower surface, and is used to install the fixed base 24 and the limiting block 22. A connecting block 26 is fixedly connected at one end to the outer wall of the top of the limiting block 22, and rotates with the limiting block 22. A tension spring 27 is fixedly connected at one end to the connecting block 26, and the other end of the tension spring is connected to... The lower surface of the fixing block 25 is fixedly installed. When the adjusting rod body 1 drives the ratchet 21 to rotate counterclockwise, the ratchet 21 teeth press against the bottom of the limiting block 22, pushing the limiting block 22 to rotate clockwise around the fixed shaft 23. This causes the connecting block 26 to stretch the tension spring 27, and the elasticity of the tension spring 27 pulls the limiting block 22 to rotate, so that the bottom of the limiting block 22 is engaged between the adjacent ratchet 21 teeth, thus limiting the ratchet 21 in one direction and ensuring the one-way adjustment of the adjusting rod body 1, thereby improving the stability and safety of the adjustment.

[0034] Furthermore, the positioning mechanism 3 includes a positioning hole 31, which is located at one end of the fixed shaft 23 and is a square slot for accommodating the positioning block 34; a screw 32, one end of which is rotatably connected to the inner wall of the positioning hole 31, and the screw 32 rotates at one end of the fixed shaft 23, thereby moving the positioning block 34; and a mounting bracket 33, one end of which is fixedly connected to the front of the fixed base 24, and the mounting bracket 33 is L-shaped for mounting... The frame 33 is used to limit the movement of the positioning block 34, so that the positioning block 34 cannot rotate; the positioning block 34 is threaded to one end of the screw 32, and one end of the positioning block 34 is slidably inserted into the inner cavity of the positioning hole 31. By rotating the screw 32, the positioning block 34 is driven along the screw 32, so that one end of the positioning block 34 slides into the inner cavity of the positioning hole 31, limiting the fixed shaft 23, so that the fixed shaft 23 and the limiting block 22 cannot rotate, thus ensuring the stability of the adjusting rod body 1.

[0035] The positioning block 34 is square in shape. One end of the positioning block 34 is slidably inserted into the mounting bracket 33. The positioning block 34 slides on the mounting bracket 33. The bottom of the limiting block 22 is inclined. The fixing block 25 has mounting holes in a rectangular array. The mounting holes are used to insert bolts for fixing the fixing block 25.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
