Description

Technical Field

[0001] The present invention relates to the technical field of travel or camping equipment, and in particular to a suitcase durability detection device capable of conveniently changing the load. Background Art

[0002] With the progress of the times, people no longer use traditional cloth packages to carry personal belongings when traveling long distances. Instead, they gradually use more novel suitcases. Compared with cloth packages, suitcases are not only larger in size and can store more things, but also have wheels installed on the bottom of the suitcases, making it more convenient for people to carry them in daily life.

[0003] Before suitcases leave the factory and enter the market, they undergo random inspections to ensure quality assurance for consumers. Conventional suitcase testing devices offer limited functionality. Sometimes, the durability of the suitcase's rollers under varying loads requires manual adjustment with weights, which is cumbersome. Furthermore, manual fixation is required during testing, impacting testing efficiency. Furthermore, when testing the roller's durability, the protrusions on the conveyor belt don't accurately simulate real road surfaces, affecting test accuracy. Therefore, we propose a suitcase durability testing device that allows for convenient load adjustment.

[0009] Furthermore, the lower end of the adjustment ring is fixedly connected to a screw, the middle outer side of the screw is engaged with a fixed sleeve, the outer side of the screw is provided with a thread, the inner side of the fixed sleeve is provided with a screw tooth, and the thread and the screw tooth are adapted in size and shape.

[0010] Furthermore, the lower end of the screw is fixedly connected to a transmission block, the side of the transmission block is provided with an inclination angle, the lower end of the transmission block is fixedly connected to a pressure rod, and elastic springs are provided on both sides of the pressure rod.

[0011] Furthermore, the left end of the transmission block is slidably connected to a sliding block, the left end of the sliding block is fixedly connected to an extrusion block, an air bag is provided on the left side of the extrusion block, and the left end of the air bag is fixedly connected to an air pipe.

[0012] Furthermore, the end of the air supply pipe away from the airbag is fixedly connected to a fixed cavity, the interior of the fixed cavity is slidably connected to a sliding piston, the right end of the sliding piston is fixedly connected to a connecting rod, the right end of the connecting rod is fixedly connected to a fixed plate, a return spring is fixedly connected above the left end of the fixed plate, and the end of the return spring away from the fixed plate is fixedly connected to the fixed cavity.

[0013] Furthermore, the inner bottom surface of the support frame is fixedly connected to a support seat, the upper end of the support seat is movably connected to a driving roller, a belt slides on the outside of the driving roller, and an irregular protrusion is provided above the outer side of the belt.

[0014] Compared with the prior art, the present invention provides a suitcase durability testing device that can conveniently change the load, which has the following beneficial effects:

[0015] 1. This suitcase durability testing device with convenient load change is as follows: first, the suitcase is placed on top of the belt. According to the test requirements, the adjustment ring is manually rotated. The adjustment ring drives the screw to rotate synchronously, causing the screw to move downward. The downward movement of the screw pushes the transmission block to move downward synchronously. When the transmission block moves, it drives the pressure rod downward. The pressure rod moves downward close to the suitcase and applies force on the suitcase. Because the elastic coefficient of the elastic spring is constant, the corresponding load force can be increased by adjusting the specified length. The required load force can be quantitatively and accurately applied by the change of the scale on the indicator needle indicating the scale, thereby achieving the beneficial effects of conveniently changing the load force and simple operation.

[0016] 2. This suitcase durability testing device that conveniently changes the load, when adjusting the load force, the rotation of the screw will drive the transmission block to move downward. Because the side of the transmission block is an inclined surface, the inclined surface of the transmission block will squeeze the sliding block to move to the left. When the sliding block moves to the left, it will drive the extrusion block to move to the left. The extrusion block squeezes the airbag to the left, so that the gas in the airbag flows into the fixed cavity through the air pipe. The gas pushes the sliding piston to the right. The sliding piston drives the fixed plate to move to the right through the connecting rod, close to the suitcase. When the fixed plates on both sides are close to the suitcase, they are clamped and fixed to prevent shaking during the test, thereby achieving the beneficial effect of automatic fixation and anti-shaking.

[0017] 3. This suitcase durability testing device with convenient load change applies load and fixes by rotating the adjustment ring, turns on the external drive, and the drive roller rotates under the drive of the external drive. When the drive roller rotates, it drives the belt to rotate synchronously. Under the action of the fixed structure of the suitcase, the roller slides on the surface of the belt. Because the outer side of the belt is provided with irregular raised blocks, it can well simulate the actual road conditions, which can effectively improve the accuracy of the test, thereby achieving the beneficial effect of accurate and effective testing.

[0027] Working principle: This suitcase durability testing device with convenient load change, when the suitcase needs to be properly tested, first place the suitcase on top of the belt 26, and manually rotate the adjusting ring 7 according to the test requirements. The adjusting ring 7 drives the screw 10 to rotate synchronously. When the screw 10 rotates, the thread engages with the teeth inside the fixed sleeve 11, causing the screw 10 to move downward. The downward movement of the screw 10 pushes the transmission block 12 to move downward synchronously. When the transmission block 12 moves, it drives the pressure rod 13 downward, and the pressure rod 13 moves downward close to the suitcase, applying force above the suitcase. Because the elastic coefficient of the elastic spring 14 is constant, the corresponding load force can be increased by adjusting the specified length. The required load force can be quantitatively and accurately applied by indicating the scale change on the scale 8 through the indicator needle 9, thereby achieving the beneficial effects of conveniently changing the load force and simple operation.

[0028] This suitcase durability testing device that conveniently changes the load, when adjusting the load force, the rotation of the screw 10 will drive the transmission block 12 to move downward. Because the side of the transmission block 12 is an inclined surface, the inclined surface of the transmission block 12 will squeeze the sliding block 15 to move to the left. When the sliding block 15 moves to the left, it will drive the extrusion block 16 to move to the left. The extrusion block 16 squeezes the airbag 17 to the left, so that the gas in the airbag 17 flows into the fixed cavity 19 through the air pipe 18. The gas pushes the sliding piston 20 to move to the right. The sliding piston 20 drives the fixed plate 22 to move to the right through the connecting rod 21 to approach the suitcase. When the fixed plates 22 on both sides are close to the suitcase, they are clamped and fixed to prevent shaking during the test, thereby achieving the beneficial effects of automatic fixation and anti-shaking.

[0029] This suitcase durability testing device with convenient load change applies load and fixes by rotating the adjustment ring 7, turns on the external drive, and under the drive of the external drive, the driving roller 25 rotates, and the driving roller 25 drives the belt 26 to rotate synchronously when rotating. Under the action of the fixed structure of the suitcase, the roller slides on the surface of the belt 26. Because the outer side of the belt 26 is provided with irregular raised blocks, it can well simulate the actual road conditions, which can effectively improve the accuracy of the test, thereby achieving the beneficial effect of accurate and effective testing.
