Description

Technical Field

[0001] The utility model relates to the technical field of damping buffers, in particular to a damping buffer with adjustable height. Background Art

[0002] A buffer damper is installed at the bottom of the elevator shaft. When the car descends to the lowest point, the bottom of the car is close to the top of the buffer damper. When inspecting the elevator, elevator maintenance personnel usually need to stand at the bottom of the elevator shaft. At this time, the bottom of the car should be at least 2 meters high, but the height of the buffer damper is usually about 0.8 meters, which does not play a role in safety protection. Therefore, other tools are needed to prevent the car from moving downward during actual maintenance.

[0003] If the existing damping buffer is designed to be telescopic, the height requirement still cannot be met, and the overlap between the two sections of the telescopic damping buffer is small when it is extended, so it is likely to bend or tilt when subjected to severe impact, posing a safety hazard.

[0004] Therefore, it is necessary to invent a highly adjustable damping buffer to solve the above problems. Utility Model Content

[0005] In order to address the deficiencies in the prior art, the purpose of the utility model is to provide a height-adjustable damping buffer, which solves the problem that when the elevator is inspected and repaired in actual use, the height of the buffer damper is usually about 0.8 meters, which does not play a safety protection role and requires other tools to prevent the car from moving downward. If the damping buffer is designed to be telescopic, when it is in the telescopic state and is subjected to severe impact, the damping buffer will bend or tilt.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0007] A height-adjustable damping buffer comprises a damping buffer body, wherein the bottom end of the damping buffer body is connected to an upper base, a cushion block is arranged at the bottom end of the upper base, upper connecting rods in a "door" structure are hinged on both sides of the upper base, a lower connecting rod in a "door" structure is hinged at the bottom end of the upper connecting rod, and the bottom end of the lower connecting rod is detachably connected to a lower base.

[0008] As a preferred solution of the utility model, the side wall of the upper connecting rod is rotatably connected with a diagonal brace, the end of the diagonal brace is provided with a hook groove with a side opening for hooking the upper connecting rod on the opposite side, and a stopper is provided at the position where the upper connecting rod and the diagonal brace groove are adapted.

[0009] As a preferred solution of the utility model, one side wall opposite to the plurality of lower connecting rods is provided with a clamping plate, and one end of the clamping plate contacting each other is clamped with a clamping tooth for ensuring the support stability of the lower connecting rod.

[0010] As a preferred solution of the utility model, a pull rod for tightening multiple clamping plates is provided at the top of the inner wall of the lower connecting rod, a nut for locking and fixing is provided at the end of the pull rod, and a screw fixing seat is provided at a position matching the nut at the bottom end of the inner wall of the lower connecting rod on the opposite side.

[0011] As a preferred solution of the utility model, a screw placement groove for accommodating the pull rod and the nut is opened at the bottom end of the lower connecting rod.

[0012] As a preferred solution of the utility model, the width of the lower connecting rod is smaller than the width of the upper connecting rod.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] In the utility model, the raising and lowering of the damping buffer is achieved by folding and unfolding two sets of connecting rods. The upper connecting rod and the lower connecting rod can be folded so that the pad is fitted with the lower base to achieve normal operation of the damping buffer. The "door"-shaped arrangement of the upper connecting rod and the lower connecting rod can ensure the overall strength and stability of the damping buffer in the supporting state. During maintenance, the damping buffer can be lifted and the diagonal brace can be rotated. The purpose of increasing the height of the damping buffer can be achieved by locking the pull rod and the screw fixing seat. The entire connecting rod structure uses pull rods and diagonal braces, so that the overall component has higher stability and impact resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0021] The utility model provides Figure 1-4 A height-adjustable damping buffer shown in the figure includes a damping buffer body 1, wherein the bottom end of the damping buffer body 1 is connected to an upper base 2, a pad 21 is arranged at the bottom end of the upper base 2, upper connecting rods 3 in a "door" structure are hinged on both sides of the upper base 2, a lower connecting rod 5 in a "door" structure is hinged at the bottom end of the upper connecting rod 3, and the bottom end of the lower connecting rod 5 is detachably connected to a lower base 7, and the damping buffer body 1 is raised by the support of the upper connecting rod 3 and the lower connecting rod 5, and the height of the damping buffer body 1 is lowered by separating the upper connecting rod 3 and the lower connecting rod 5 on both sides, and the connecting rod length is controllable and the stability is good in the supported state.

[0022] The side wall of the upper connecting rod 3 is rotatably connected with a diagonal brace 4, and the end of the diagonal brace 4 is provided with a hook groove with a side opening for hooking the upper connecting rod 3 on the opposite side. A stopper is provided at a position where the upper connecting rod 3 and the diagonal brace 4 groove are adapted. The stopper can be a pin or a bolt. Through the setting of the diagonal brace 4, when the damping buffer body 1 is in the expanded state, the stopper is hooked by the diagonal brace 4, so that the upper connecting rod 3 and the diagonal brace 4 form a plurality of triangular structures, thereby achieving the purpose of fixing the upper and middle parts of the upper equipment, so that the overall equipment has higher stability and impact resistance.

[0023] A clamping plate 6 is provided on one side wall opposite to the plurality of lower connecting rods 5 . One end of the clamping plates 6 that contacts each other is clamped with a clamping tooth for ensuring the supporting stability of the lower connecting rod 5 . The clamping teeth are clamped with each other, thereby improving the load-bearing stability of the lower connecting rod 5 .

[0024] A pull rod 8 for tightening multiple clamping plates 6 is provided at the top end of the inner wall of the lower connecting rod 5, and a nut 82 for locking and fixing is provided at the end of the pull rod 8. A screw fixing seat 81 is provided at a position matching the nut 82 at the bottom end of the inner wall of the opposite lower connecting rod 5. By rotating the nut 82, the clamping teeth of the lower connecting rod 5 can be squeezed inward to ensure the stability of the support of the two groups of lower connecting rods 5 and ensure the stable operation of the top assembly.

[0025] The bottom end of the lower connecting rod 5 is provided with a screw placement groove 51 for accommodating the pull rod 8 and the nut 82. The purpose of setting the screw placement groove 51 is that when the equipment is in a folded state, the pull rod 8 inside the lower connecting rod 5 is accommodated in the screw placement groove 51, so that the cushion block 21 can fit tightly with the lower base 7, so that when the device is in a folded state, the damping buffer body 1 still has good stability.

[0026] The width of the lower connecting rod 5 is smaller than that of the upper connecting rod 3. When the device is in a folded state, the lower connecting rod 5 can be stored inside the upper connecting rod 3, so that the damping buffer body 1 can accurately meet the use requirements during the operation of the car.

[0027] The utility model realizes the raising and lowering of the damping buffer by folding and unfolding two sets of connecting rods. The upper connecting rod 3 and the lower connecting rod 5 can be folded so that the cushion block 21 fits with the lower base 7 to realize the normal operation of the damping buffer. The "door"-shaped arrangement of the upper connecting rod 3 and the lower connecting rod 5 can ensure the overall strength and stability of the damping buffer in the supporting state. During maintenance, the damping buffer can be lifted and the diagonal brace 4 can be rotated. The purpose of increasing the height of the damping buffer can be achieved by locking the pull rod 8 and the screw fixing seat 81. The entire connecting rod structure uses the pull rod 8 and the diagonal brace 4, so that the overall component has higher stability and impact resistance.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
