Secondly, the manufacturing cost is high. Therefore, there is an urgent need for a reset trigger mechanism for an elevator buffer to solve the above technical problems. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a reset trigger mechanism for an elevator buffer to solve the problems of the existing reset trigger mechanism of the elevator buffer, which usually has a complex structure, a cumbersome reset action, poor effects after long-term use, and secondly, a high manufacturing cost, as mentioned in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A reset trigger mechanism for an elevator buffer includes a cylinder block. A spring is arranged on the outer side of the top of the cylinder block. An oil seal is arranged at the top inside the cylinder block. A piston rod is arranged at the axis of the cylinder block. A pressure accumulator sponge is arranged inside the cylinder block and directly below the oil seal. A piston is arranged directly below the pressure accumulator sponge. An oil injection hole is arranged at the bottom of the cylinder block. A check valve is arranged at the top of the oil injection hole. A chamber is arranged at the middle inside the cylinder block. The piston is located in the chamber. The bottom of the piston rod is connected with a reset pressing block. A pressing column is connected to the center of the lower end of the reset pressing block. A reset spring is sleeved on the pressing column. A ring is arranged directly below the reset pressing block. The lower end of the pressing column passes through the center of the ring and is connected with a first connecting block. Both sides of the inner side wall of the chamber are connected with second connecting blocks. Both sides of the top of the first connecting block are connected with lower contacts. Both bottoms of the two second connecting blocks are connected with upper contacts.
[0007] As a preferred technical solution of the utility model, the check valve is communicated with the chamber through a conveying channel.
[0008] As a preferred technical solution of the utility model, a sealing rubber ring is sleeved on the outer side of the reset pressing block, and the sealing rubber ring can move up and down along the inner side wall of the chamber.

At this time, the reset spring is compressed, and the upper contact point and the lower contact point on the first connecting block and the second connecting block are separated, so that the traction machine is powered off. When the elevator car or the counterweight leaves the buffer, the reset spring resets, causing the upper contact point and the lower contact point to come into contact, closing the circuit, and enabling the traction machine to be in a normal use state. Thus, the structure is simple, the reset is simple, the effect is still good after long-term use, and the manufacturing cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and do not limit the utility model. Additionally, it should be noted that for the sake of convenience of description, only the parts related to the utility model are shown in the drawings. In the drawings of the embodiments of the present utility model: Different types of hatching lines in the figures are not marked according to the national standard, nor are the materials of the components required. It is to distinguish the cross-sectional views of the components in the figures.
[0021] Please refer to Figures 1-4 , a reset trigger mechanism for an elevator buffer, including a cylinder block 1. A spring 2 is arranged on the outer side of the top of the cylinder block 1. An oil seal 3 is arranged at the inner top of the cylinder block 1. A piston rod 6 is arranged at the axis of the cylinder block 1. A pressure accumulator sponge 4 is arranged inside the cylinder block 1 and directly below the oil seal 3. A piston 5 is arranged directly below the pressure accumulator sponge 4. An oil injection hole 8 is arranged at the bottom of the cylinder block 1. A check valve 7 is arranged at the top of the oil injection hole 8. A chamber 17 is arranged at the middle inside the cylinder block 1. The piston 5 is located inside the chamber 17. The bottom of the piston rod 6 is connected with a reset pressing block 9. A downward pressing column 11 is connected to the center of the lower end of the reset pressing block 9. A reset spring 12 is sleeved on the downward pressing column 11. A ring 19 is arranged directly below the reset pressing block 9. The lower end of the downward pressing column 11 passes through the center of the ring 19 and is connected with a first connecting block 15. Second connecting blocks 13 are connected to both sides of the inner side wall of the chamber 17. Lower contacts 16 are connected to both sides of the top of the first connecting block 15. Upper contacts 14 are connected to the bottom of both second connecting blocks 13.
[0022] Among them, the check valve 7 is communicated with the chamber 17 through a conveying channel 18, so that the oil path is unobstructed and enters the cylinder block 1 from the side, thus avoiding affecting the reset structure.
[0023] Among them, a sealing rubber ring 10 is sleeved on the outer side of the reset pressing block 9. The sealing rubber ring 10 can move up and down along the inner side wall of the chamber 17, so that the up and down movement of the reset pressing block 9 can be realized.
[0024] Among them, the lower contacts 16 are directly opposite to the upper contacts 14, so as to achieve a stable electrical connection.
[0025] Among them, the downward pressing column 11 is located between the two second connecting blocks 13, so as not to affect the up and down movement of the downward pressing column 11.
[0026] Among them, there is a gap between the reset pressing block 9 and the ring 19, so that the reset spring 12 has enough compression and extension space.
[0027] Working principle and usage process of the present utility model: First, when the elevator car touches and presses down the buffer, it will drive the piston rod 6 to move downward and press down the reset block 9, causing the reset block 9 to move downward and drive the downward pressing column 11 to move downward. At this time, the reset spring 12 is compressed, and the upper contact 14 and the lower contact 16 on the first connecting block 15 and the second connecting block 13 are separated, cutting off the power supply of the traction machine. When the elevator car or the counterweight leaves the buffer, the reset spring 12 resets, causing the upper contact and the lower contact to come into contact, closing the circuit, and putting the traction machine in a normal working state. This makes the structure simple, the reset simple, and the effect remains good after long-term use. The manufacturing cost is low. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
