Description

Technical Field

[0001] This utility model belongs to the field of drawer slide testing technology, specifically relating to a device for testing the wear resistance of drawer slides. Background Technology

[0002] In today's furniture manufacturing industry, drawer slides are an important component of drawers. The wear resistance of drawer slides directly affects their service life. Before leaving the factory, wear resistance testing is required to ensure their quality. Existing testing methods mostly rely on manual operation of the drawer slides to reciprocate and observe the wear, which has problems such as low efficiency and inconsistent testing conditions. Moreover, existing traditional devices can only simulate a single environment, which may lead to insufficient reliability of the test results. Therefore, it is necessary to design a drawer slide wear resistance testing device. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a device for testing the wear resistance of drawer slides.

[0004] The objective of this utility model can be achieved through the following technical solution: A drawer slide rail wear resistance testing device includes a base, with support feet provided at the four corners of the bottom of the base. The base is characterized by having two symmetrical mounting plates, each with mounting holes for mounting drawer slide rails. A platform is provided on the base, and a push rod motor is horizontally mounted on the platform. The base also includes a spraying mechanism for spraying powder and water mist. The spraying mechanism includes a column, a support plate, a powder spraying component, and a water mist spraying component. The column is vertically mounted on the base, and the support plate is positioned above the column and hinged to it. The powder spraying component is located at one end of the mounting plate, and the water mist spraying component is located at one end of the mounting plate. The support plate is slightly higher than the two mounting plates.

[0005] The working principle of this utility model is as follows: The operator installs the drawer slide rails that need to be tested for wear resistance on two mounting plates, installs the drawer on the drawer slide rails, and connects the push rod of the push rod motor to the drawer pull ring. The push rod motor drives the drawer to reciprocate on the drawer slide rails to test its wear resistance. If it is necessary to simulate a dusty or humid home environment, a spraying mechanism can be used to simulate the environment for the two sets of slide rails respectively. At the same time, the operator can add weight to the drawer to simulate the situation when placing items in it during use. In addition, when it is necessary to disassemble the drawer slide rails and the drawer before or after the test, the operator can rotate the support plate to the side to prevent the support plate from causing inconvenience to the disassembly operation. The automated device drives the drawer to reciprocate on the drawer slide rails, which improves efficiency and can simulate various home environments, increasing the reliability of the test results.

[0006] The powder spraying assembly includes a hopper, a conveyor, a pressure chamber, and a nozzle. The hopper is located above a support plate, the conveyor is located inside the support plate and its upper end is connected to the hopper, the pressure chamber is connected to the lower end of the conveyor, the nozzle is connected to the pressure chamber, and a screen is connected below the nozzle.

[0007] Using the above structure, the operator adds powder to the hopper, and the powder enters the pressure chamber through the conveyor. The powder is then sprayed through the nozzle to simulate a dusty household environment. At the same time, the filter screen is used to sieve the powder to prevent fragments from damaging the slide rail.

[0008] The water mist spraying assembly includes a water storage tank, a spray pipe, an air pipe, and a pump body. The water storage tank is located above the support plate. One end of the spray pipe is connected to the bottom of the water storage tank, and the other end of the spray pipe is inserted through the support plate. The air pipe is connected to the middle of the spray pipe, and the pump body is installed in the middle of the air pipe. One end of the air pipe is inserted through the support plate and connected to the outside.

[0009] Using the above structure, the operator adds water to the water storage tank, pressurizes the water to the required high pressure through the air pipe and pump body, and then sprays it out in an atomized state through the nozzle to simulate the humid environment in the home.

[0010] With the above structure, the drawer pull ring can be secured and locked by extending and retracting the buckle of the connecting buckle.

[0011] The base is equipped with a display screen and buttons.

[0012] With the above structure, the number of tests can be displayed through the screen and buttons, and the start, pause and stop of the reciprocating motion of the drawer slide can be controlled.

[0013] Compared with existing technologies, this drawer slide wear resistance testing device has the following advantages: through the setting of the spraying mechanism and the push rod motor, there is no need for operators to manually drive the drawer to move back and forth on the drawer slide, which improves the testing efficiency. It can also simulate household environments such as dust, humidity and load, which increases the reliability of the test results. Attached Figure Description
