Description

Technical Field

[0001] This utility model relates to the field of gas spring testing technology, and in particular to a device for testing the number of times a gas spring has been extended and contracted. Background Technology

[0002] The gas spring extension fatigue cycle testing equipment is mainly used to simulate the reciprocating extension and retraction of gas springs during long-term use. By setting parameters such as the number of cycles and speed, it detects the performance changes under continuous force, such as the attenuation of extension force, sealing performance, and structural integrity. This allows for the evaluation of the fatigue life and reliability of the gas spring, providing data support for product quality improvement, selection, and industry standard formulation.

[0003] In the field of gas spring performance testing, existing testing equipment has significant limitations. Different equipment employs testing methods that lack unified standards and are out of touch with actual usage environments. For example, they ignore complex operating conditions such as vibration and temperature changes, leading to significant deviations between test data and real-world usage conditions. This makes it difficult to accurately reflect product performance. Furthermore, the equipment is generally bulky and cumbersome, with complex internal structures, making installation and debugging tedious. Relocation requires professional personnel and hoisting equipment, consuming substantial manpower and resources and severely limiting its flexibility, making it difficult to meet diverse and multi-scenario testing needs.

[0004] Therefore, this application provides a gas spring extension fatigue cycle testing device to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and to propose a device for testing the fatigue cycles of gas spring extension and contraction.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a gas spring extension fatigue cycle testing device, including a base frame, and further comprising:

[0007] A reciprocating motor is installed at the top of the base frame. A bending connecting rod is installed on one side of the reciprocating motor. A handlebar stem is installed at the other end of the bending connecting rod. A fixed post is rotatably installed at the bottom of the handlebar stem. A gas spring body is installed on one side of the handlebar stem. The other end of the gas spring body is connected to one side of the fixed post.

[0008] Furthermore, a support frame is provided on the top of the base frame, and a guide plate is provided on the top of the support frame. One side of the guide plate is fixedly connected to the reciprocating motor, and the bottom of the reciprocating motor passes through the guide plate and is connected to the bending connecting rod.

[0009] The beneficial effects of adopting the above-mentioned further solution are as follows: a support frame is provided at the top of the base frame to provide support, and a guide plate at the top of the support frame is used to fix the reciprocating motor to ensure that the motor is installed firmly. The bottom of the reciprocating motor passes through the guide plate and is connected to the bending connecting rod. When the reciprocating motor is running, it can output power stably through the guide plate to drive the bending connecting rod to move, providing a power basis for the operation of subsequent components.

[0010] Furthermore, a counting sensor is provided on one side of the bottom of the reciprocating motor, and a counter is provided on the top of the reciprocating motor.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the counting sensor on one side of the bottom of the reciprocating motor can monitor the motion state, and the counter on the top can record the number of times the gas spring extends and retracts.

[0012] Furthermore, a base is provided on the side of the base away from the support frame, and the top of the base is connected to the bottom of the fixed column.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the base is provided on the side of the base frame away from the support frame, and its top is connected to the bottom of the fixed column, providing stable support for the fixed column and ensuring structural stability during gas spring testing.

[0014] Furthermore, positioning holes are provided on both sides of the base.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the positioning holes on both sides of the base can be used to achieve precise positioning and stable installation of the base through bolts and other connecting parts.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] The base frame serves as the basic load-bearing component, with a reciprocating motor mounted on top as the power source. Its output shaft is connected to a bending connecting rod, which converts the motor's rotational motion into the reciprocating motion of the handlebar stem. The bottom of the handlebar stem is rotatably connected to a fixed post, with a gas spring body connected to one side. The other end of the gas spring body is connected to the fixed post. In this way, the motor's operation drives the handlebar stem to move, causing the gas spring body to repeatedly extend and retract, thus enabling the testing of its extension and retraction fatigue cycles.

[0024] 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.

[0025] like Figures 1-4 As shown, this utility model provides a technical solution: a gas spring extension fatigue cycle testing device, including a base frame 1, and further including:

[0026] A reciprocating motor 6 is installed on the top of the base frame 1. A bending connecting rod 4 is installed on one side of the reciprocating motor 6. A handlebar tube 8 is installed at the other end of the bending connecting rod 4. A fixed column 11 is rotatably installed at the bottom of the handlebar tube 8. A gas spring body 9 is installed on one side of the handlebar tube 8. The other end of the gas spring body 9 is connected to one side of the fixed column 11. The base frame 1 serves as the basic load-bearing component. The reciprocating motor 6 installed on the top is the power source. Its output shaft is connected to the bending connecting rod 4, which can convert the rotational motion of the motor into the reciprocating motion of the handlebar tube 8. The bottom of the handlebar tube 8 is rotatably connected to the fixed column 11, and one side is connected to the gas spring body 9. The other end of the gas spring body 9 is connected to the fixed column 11. In this way, the motor drives the handlebar tube 8 to move, causing the gas spring body 9 to repeatedly extend and retract, thereby achieving the test of its extension and retraction fatigue number.

[0027] Furthermore, such as Figures 1-4 As shown: A support frame 2 is provided on the top of the base frame 1, and a guide plate 3 is provided on the top of the support frame 2. One side of the guide plate 3 is fixedly connected to the reciprocating motor 6. The bottom of the reciprocating motor 6 passes through the guide plate 3 and is connected to the bending connecting rod 4. The support frame 2 on the top of the base frame 1 serves as a support, and the guide plate 3 on its top is used to fix the reciprocating motor 6 to ensure that the motor is installed firmly. The bottom of the reciprocating motor 6 passes through the guide plate 3 and is connected to the bending connecting rod 4. When the motor is running, it can stably output power through the guide plate 3 to drive the bending connecting rod 4 to move, providing a power basis for the subsequent component movements.

[0028] The above solutions still have counting problems, such as... Figures 1-4As shown: In this scheme, a counting sensor 5 is provided on one side of the bottom of the reciprocating motor 6, and a counter 7 is provided on the top of the reciprocating motor 6. The counting sensor 5 on one side of the bottom of the reciprocating motor 6 can monitor the motion status, and the counter 7 on the top can record the number of times the gas spring extends and retracts.

[0029] Working principle: such as Figures 1-4 As shown, the base frame 1 serves as the fundamental load-bearing component of the entire equipment. A support frame 2 is mounted on one side of its top, and a base 10 is mounted on the other side. A guide plate 3 is installed on the top of the support frame 2 to fix the reciprocating motor 6, ensuring stable installation and providing a stable operating foundation. The output shaft of the reciprocating motor 6 is connected to a bent connecting rod 4, converting the motor's rotational motion into the reciprocating motion of the riser tube 8. The bottom of the riser tube 8 is rotatably connected to the base 10 via a fixing column 11, with a gas spring body 9 connected to one side. The other end of the gas spring body 9 is connected to the fixing column 11. When the reciprocating motor 6 operates, it outputs power stably through the guide plate 3, driving... The moving bending linkage 4 moves, which in turn drives the upright tube 8 to swing back and forth around the fixed column 11, causing the gas spring body 9 to repeatedly extend and retract, thus testing its extension and retraction fatigue number. The counting sensor 5 set on one side of the bottom of the reciprocating motor 6 can monitor the motor's motion status in real time, and the counter 7 set on the top records the extension and retraction number of the gas spring body 9 according to the signal feedback from the sensor, making it convenient for users to obtain test data. The positioning holes 12 on both sides of the base 10 can be used to achieve precise positioning and stable installation of the base 10 on the base frame 1 through bolts and other connecting parts, ensuring structural stability throughout the test process and improving the accuracy and reliability of the test results.
