Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing technology, and in particular relates to an adjustable slide rail impact performance testing device. Background Technology

[0002] As a crucial component of mechanical equipment, slide rails are widely used in furniture, automobiles, rail transportation, and other fields. During use, they are frequently subjected to external impact loads, directly affecting the reliability and service life of the product. Therefore, the impact performance of slide rails is one of the key indicators for measuring their quality, and accurate and efficient impact performance testing equipment is essential for the research and development and quality control of slide rails.

[0003] Currently, existing slide rail impact performance testing devices have the following technical shortcomings:

[0004] 1. Insufficient testing accuracy: Existing devices lack high-precision displacement measurement and impact simulation components, making it impossible to accurately simulate impact loads under actual working conditions. Furthermore, it is difficult to accurately quantify key parameters such as displacement and deformation of the slide rail during the impact process, resulting in insufficient reliability of test data and affecting the objective evaluation of slide rail performance.

[0005] 2. Fixed structure and poor adaptability: Traditional testing devices have a relatively fixed structural design, making it difficult to adapt to slide rails of different lengths and specifications. When testing various types of slide rails, frequent equipment changes or fixture adjustments are required, resulting in low testing efficiency, increased operational complexity, and an inability to meet the demands of modern manufacturing for efficient and flexible testing.

[0006] 3. Lack of stability: Due to insufficient overall structural strength, the device is prone to overall shaking or loosening of local components when subjected to high impact loads. This not only affects the accuracy of test data but may also reduce the service life of the equipment and increase maintenance costs.

[0007] In summary, existing slide rail impact performance testing devices have significant shortcomings in terms of structural adaptability, testing accuracy, and stability, making it difficult to meet the increasingly demanding requirements for slide rail performance testing. Therefore, there is an urgent need to develop a slide rail impact performance testing device with adjustable structure, precise measurement, and high stability to improve testing efficiency, ensure data reliability, extend equipment lifespan, and provide effective support for slide rail design optimization and quality control. Utility Model Content

[0008] The purpose of this invention is to solve the above-mentioned problems in the prior art and to provide an adjustable slide rail impact performance testing device.

[0009] The objective of this utility model is achieved through the following technical solution:

[0010] An adjustable slide rail impact performance testing device includes a support frame with a set of parallel guide shafts and measuring scales arranged along its height direction. A slider spans the guide shafts and moves along their direction. The front of the slider is connected to a telescopic slide rail via bolts, and the back of the slider is connected to the support frame via a plunger. The installation height of the plunger is adjustable. In the initial state, the end of the plunger penetrates the support frame and extends into the slider to limit the test height of the slider; at this time, the slide rail is in an extended state. In the terminated state, the end of the plunger penetrates the support frame and disengages from the slider, and the slider falls from the test height under its own weight; at this time, the slide rail is in a retracted state. Repeating the above operation can detect the impact resistance of the slide rail at the same height. By continuously adjusting the height of the plunger, the fatigue resistance of the slide rail under impact at different heights can be detected to determine the ultimate impact height of the slide rail.

[0011] Preferably, the plunger is mounted on the bracket via a connecting plate located on the back of the bracket and connected to it by bolts; the connecting plate has a set of mounting holes for mounting the plunger.

[0012] Preferably, the bracket has a first waist-shaped hole, which is centrally located between two adjacent guide shafts; and the length of the first waist-shaped hole is greater than the length of the connecting plate; the end of the plunger is located in the first waist-shaped hole.

[0013] Preferably, the bracket is further provided with a set of bolt holes, and the connecting plate is further provided with a second oblong hole for mounting bolts, and the second oblong hole is located on both sides of the plunger.

[0014] Preferably, the end of the plunger is formed with a bevel that matches the slider.

[0015] Preferably, a set of counterweights is stacked on the top front of the slider by bolts.

[0016] Preferably, the slider has two pulleys at the bottom front end, and the pulleys are located on both sides of the slide rail.

[0017] Preferably, the length of the measuring ruler is not less than the height of the bracket.

[0018] Preferably, the guide shaft is provided with a coating.

[0019] The advantages of this utility model's technical solution are mainly reflected in:

[0020] By moving the slide rail to any height on the steel ruler using a slider, the performance parameters of the slide rail after being impacted at a certain height are simulated, thereby improving the accuracy and reliability of the test.

[0021] By setting a guide shaft on the bracket to ensure the overall structural strength of the device, and setting a slider on the guide shaft to ensure the movement direction of the slider and slide rail during the test, the shaking or loosening is reduced and the accuracy of the test data is improved.

[0022] The slide rail is fixed to the slider, and the slider drives the slide rail to move and extend. It can adapt to slide rails of different lengths and specifications, and can also test the test requirements of the same slide rail at different heights, or test the performance of different slide rails at the same height. It does not require frequent replacement of equipment or spare parts, and is highly flexible and widely applicable. Attached Figure Description

[0026] The purpose, advantages, and features of this utility model will be illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of applying the technical solutions of this utility model, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of protection claimed by this utility model.

[0027] In the description of the solution, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience and simplification of description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Also, in the description of the solution, with the operator as a reference, the direction closer to the operator is the proximal end, and the direction farther from the operator is the distal end.

[0028] like Figures 1 to 3As shown, this utility model discloses an adjustable slide rail impact performance testing device, including a support 1. A measuring ruler 12 is arranged on the support 1 along its height direction, and the length of the measuring ruler 12 is not less than the height of the support 1. The measuring ruler 12 can be used to repeatedly test the slide rail's impact resistance at the same height, or to test the slide rail's fatigue resistance under impact at different heights, so as to determine the slide rail's limit impact height.

[0029] In addition, to ensure stability during the testing process, it is preferable that a set of parallel guide shafts 11 are also provided on the bracket 1, and the guide shafts 11 are arranged along the height direction of the bracket 1.

[0030] Furthermore, a slider 13 spans the guide shaft 11 and moves along the direction of the guide shaft 11. The front of the slider 13 is connected to a retractable slide rail by bolts. Specifically, the slide rail may consist of two or more slide rail segments, with the foremost slide rail segment fixed to the slider 13. By having the slider 13 drive the slide rail to move and extend, the testing requirements of slide rails of different lengths or specifications can be met without replacing equipment or accessories. Furthermore, this invention preferably provides a coating on the guide shaft 11, which can be made of known materials including Teflon. Applying a coating to the guide shaft 11 reduces friction between the guide shaft and the slider, thereby reducing wear and extending their service life. In addition, in other embodiments, components such as ball bearings or bearings can be provided inside the slider to reduce friction between the slider and the guide shaft.

[0031] like Figures 2 to 3As shown, the back of the slider 13 is connected to the bracket 1 via a plunger 14, and the installation height of the plunger 14 is adjustable. Furthermore, the end of the plunger 14 has an inclined surface that matches the slider 13. In the initial state, the end of the plunger 14 penetrates the bracket 1 and extends into the slider 13 to limit the test height of the slider 13; at this time, the slide rail is in the extended state, and the inclined surface on the slider 13 is above the inclined surface on the plunger 14. In the terminated state, the end of the plunger 14 penetrates the bracket 1 and disengages from the slider 13, and the slider 13 falls from the test height under its own weight; at this time, the slide rail is in the retracted state, and the inclined surface on the slider 13 is below the inclined surface of the plunger 14. An external force drives the slider 13 upward. When the slider 13 contacts the plunger 14, a force is applied to the plunger 14, driving it away from the slider 13 via an inclined plane until the inclined plane on the slider 13 moves above the plunger 14. Repeating the above operation can test the impact resistance of the slide rail at the same height; by continuously adjusting the height of the plunger 14, the fatigue resistance of the slide rail under impact at different heights can be tested to determine the ultimate impact height of the slide rail.

[0032] Specifically, such as Figure 2 As shown, the plunger 14 is mounted on the bracket 1 via a connecting plate 141, which is located on the back of the bracket 1 and connected to it by bolts. Further, the bracket 1 has a first oblong hole 10, centrally located between two adjacent guide shafts 11; the length of the first oblong hole 10 is greater than the length of the connecting plate 141, allowing the connecting plate 141 to be mounted at any height on the bracket 1 along the direction of the first oblong hole 10. The bracket 1 also has a set of bolt holes for mounting the connecting plate 141; the end of the plunger 14 is located in the first oblong hole 10. The connecting plate 141 has a set of mounting holes 140 for mounting the plunger 14. The connecting plate 141 also has second oblong holes 142 for accommodating bolts, located on both sides of the plunger 14. Bolts are sequentially passed through the second oblong hole 142 and installed in the bolt holes on the bracket 1. The installation position of the connecting plate 141 is defined by the first oblong hole 10 and the second oblong hole 142, thereby determining the test height of the slide rail, so that the test height can be adjusted according to test requirements and / or slide rail specifications.

[0033] like Figure 1As shown, a set of counterweights 131 are bolted to the top front of the slider 13. The number of counterweights 131 can be adjusted as needed. The counterweights 131 can simulate the deformation of the slide rail under different forces, thereby testing the slide rail's durability. In addition, two pulleys 132 are provided at the bottom front of the slider 13, located on both sides of the slide rail. The pulleys 132 limit the two sides of the slide rail, ensuring that the slide rail will not wobble or tilt during the test, thereby improving the test quality.

[0034] like Figure 3 As shown, a buffer pad 15 is also provided at the bottom of the bracket 1. The buffer pad 15 is located directly below the slide rail to reduce the degree of deformation of the slide rail and the degree of damage to the bracket during the test, thereby improving the service life.
