Description

Technical Field

[0001] The present invention relates to the technical field of detecting the wear resistance of the outer layer of luggage, and specifically to a testing device and method for detecting the wear resistance of the outer layer of luggage. Background Art

[0002] During daily travel, especially during longer trips, people often need to carry various luggage to meet various daily needs during the trip. Luggage is a container for placing and carrying various items required for travel. The most common one is the rolling luggage with a handle, which is widely used during travel due to its large capacity and easy mobility.

[0003] With the development of society and the improvement of economic level, people's requirements for luggage are not only limited to being strong and having a large capacity. People are increasingly pursuing the fashionability and aesthetics of luggage. Therefore, various fashionable and beautiful luggage have been produced. However, luggage is often in a moving or handling state during use. Therefore, the outer layer of luggage is inevitably worn. Once the wear resistance of the outer layer of luggage is poor, it is easily scratched, which seriously affects the aesthetics of the luggage. Therefore, it is necessary to detect the wear resistance of the outer layer of luggage.

[0004] However, most of the existing testing devices for the wear resistance of the outer layer of luggage are to make the outer layer material of the luggage into test samples that meet the requirements, and then place the test samples into the wear resistance testing device for wear resistance testing. Although this testing method can detect the wear resistance of the outer layer material of the luggage, it cannot simulate the wear situation of the luggage during movement, so it is difficult to detect whether the easily worn outer parts of the luggage have sufficient wear resistance in various moving use scenarios, and it is impossible to more accurately and reliably detect the wear resistance of the outer layer of the luggage. For this reason, there is an urgent need for a testing device and method for detecting the wear resistance of the outer layer of luggage. Summary of the Invention

[0005] The purpose of the present invention is to provide a testing device and method for detecting the wear resistance of the outer layer of luggage to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A testing device for detecting the wear resistance of the outer layer of a luggage, comprising: a base; two vertical plates are symmetrically and fixedly connected to the top of the base, and two cross bars are symmetrically and fixedly connected to the side surfaces of the two vertical plates close to each other. Two fixing plates are fixedly connected to the side surfaces of the two cross bars close to each other. A circular rotating box is rotatably sleeved between the outer peripheral surfaces of the two cross bars. A box door is hinged to the back of the rotating box. A rotating assembly for driving the rotating box to rotate self is connected to the base. A plurality of friction plates are fixedly connected in an annular shape at equal angles between the front and rear inner side walls of the rotating box. The materials of the plurality of friction plates are different from each other. A left and right moving assembly is connected to the two fixing plates. A clamping assembly is connected to the left and right moving assembly through a lifting assembly;

[0007] The left and right moving assembly includes two moving blocks symmetrically distributed in the front and rear. The lifting assembly is connected to the bottoms of the two moving blocks. The left and right moving assembly is used to drive the lifting assembly to move left and right reciprocally;

[0008] The clamping assembly is used to clamp the luggage to be detected.

[0009] Preferably, the clamping assembly includes two first connecting plates symmetrically connected to the lifting assembly in the front and rear. Two first electric push rods are symmetrically and fixedly connected to the side surfaces of the two first connecting plates close to each other. Two connecting rods are symmetrically and fixedly connected to the output ends of the two first electric push rods. Two clamping plates are symmetrically hinged to the ends of the two connecting rods close to each other. Two second electric push rods are symmetrically hinged between the side surfaces of the two clamping plates away from each other and the side surfaces of the two first connecting plates close to each other. The advantage of such a setting is that by respectively extending and contracting the two second electric push rods, the two clamping plates can be driven to rotate in opposite directions, and then the two clamping plates are pushed by the two first electric push rods to clamp the luggage. In this way, the luggage can be driven to swing in the vertical plane, so that the edges and corners of the luggage can also be rubbed against the friction plates, so as to be able to more fully and comprehensively test the wear resistance of the outer layer of the luggage, effectively improving the test reliability of the testing device.

[0010] Preferably, the lifting assembly is two third electric push rods symmetrically and fixedly connected to the bottoms of the two moving blocks. The advantage of such a setting is that the third electric push rods can stably and reliably drive the luggage to move up and down, so as to ensure that the wear resistance test work can be carried out stably, effectively improving the reliability of the testing device.

[0011] Preferably, a flipping assembly is provided on the clamping assembly. The flipping assembly is used to drive the two clamping plates to rotate. The advantage of this setting is that the flipping assembly can drive the luggage to flip so that different sides of the luggage can rub against the friction plate, thereby reducing the number of times the staff manually adjusts the position of the luggage, reducing the labor intensity of the staff and improving the testing efficiency of the testing equipment.

[0012] Preferably, an auxiliary detection assembly is connected inside the rotating box. The auxiliary detection assembly can detect the wear resistance of local positions on the surface of the luggage. The advantage of this setting is that it can more fully and thoroughly test the wear resistance of the outer layer of the luggage, greatly improving the testing accuracy and reliability of the testing equipment.

[0013] Preferably, the auxiliary detection assembly includes multiple groups of receiving cavities that are annularly opened at equal angles on the adjacent sides of multiple friction plates. Each group of multiple receiving cavities are equidistantly distributed from front to back. Multiple groups of friction blocks are annularly and movably connected at equal angles in the multiple groups of receiving cavities. Each group of friction blocks consists of a row of friction blocks. The material of each group of multiple rows of friction blocks is the same as that of the friction plate where they are located. The cross-sectional shapes of the sides of multiple friction blocks in each row close to the axis of the rotating box are different. Each row of friction blocks is linearly distributed from left to right. The auxiliary detection assembly further includes a pushing mechanism connected to the base. The pushing mechanism is used to push a specified number of rows of friction blocks out of the receiving cavities and make them contact and rub against the outer surface of the luggage to be detected. The advantage of this setting is that friction blocks with different shapes can rub against the outer layer of the luggage, so as to more comprehensively simulate different friction scenarios, further improving the testing accuracy and reliability of the wear resistance of the luggage.

[0014] Preferably, the pushing mechanism includes multiple mounting blocks that are annularly and fixedly connected to the inner side wall of the rotating box at equal angles. The multiple mounting blocks are respectively located between multiple friction plates and the inner side wall of the rotating box. The pushing mechanism further includes multiple groups of top plates fixedly connected to the sides of multiple groups of friction blocks away from the axis of the rotating box. Multiple groups of ejector rods are annularly and fixedly connected to the sides of multiple groups of top plates away from the axis of the rotating box at equal angles. One ends of the multiple groups of ejector rods away from the axis of the rotating box are movably inserted into the outer side wall of the rotating box and extend to the outside of the rotating box. Multiple groups of elastic members are fixedly connected between the sides of multiple groups of top plates away from the axis of the rotating box and the sides of the multiple mounting blocks. The pushing mechanism further includes a jacking unit connected to the top of the base. The jacking unit is used to jack up some or all of the multiple ejector rods at the bottommost position. The advantage of this setting is that by the jacking unit jacking up some or all of the multiple ejector rods at the bottommost position, various friction blocks with different specified shapes can be made to rub against the outer layer of the luggage orderly according to the pre-setting, so as to greatly improve the testing accuracy and reliability of the wear resistance.

[0015] Preferably, the jacking unit includes a fourth electric push rod at the top of the base. A push block is fixedly connected to the output end of the fourth electric push rod. The push block is directly below the bottoms of some or all of the multiple top rods at the bottommost position. The push block moves upward to jack up some or all of the multiple top rods at the bottommost position. The advantage of this setting is that through the intermittent expansion and contraction of the fourth electric push rod, it can cooperate with the rotation of the rotating box to enable each friction block to have the opportunity to contact and rub against the outer layer of the luggage, so that different friction test schemes can be flexibly designed according to the concave and convex shapes of each side of the outer layer of the luggage, effectively improving the accuracy and reliability of the wear resistance performance test of the test equipment.

[0016] Preferably, the number of the fourth electric push rods is multiple groups. The number of each group of the fourth electric push rods is equal to the number of rows of each group of the friction blocks and is respectively located directly below a group of multiple rows of friction blocks at the bottommost position. The number of the push blocks is multiple groups. The bottoms of the multiple groups of push blocks are respectively fixedly connected to the output ends of the multiple groups of fourth electric push rods. The expansion and contraction height and whether to expand and contract of each group of multiple fourth electric push rods can be preset in advance. The jacking unit further includes a carrier plate slidably connected left and right on the top of the base. The jacking unit further includes a fifth electric push rod fixedly connected to the top of the base. The output end of the fifth electric push rod is fixedly connected to the right side surface of the carrier plate. The advantage of this setting is that by presetting the expansion and contraction height of multiple groups of fourth electric push rods, it can accurately make each friction block rub against the designated position of the outer layer of the luggage with different extrusion forces according to the preset friction test scheme, so that the test equipment can have more diverse wear resistance performance test schemes, and thus can further improve the accuracy and practicability of the wear resistance performance test.

[0017] A test method for the above solution includes the following steps:

[0018] S1: Open the door of the rotating box and place the luggage to be detected at the clamping position of the clamping assembly;

[0019] S2: Start the lifting assembly to drive the clamping assembly to move downward to a suitable height, and then start the clamping assembly to clamp the luggage;

[0020] S3: Start the lifting assembly to push the bottom surface of the luggage downward against the top surface of the lowermost friction plate through the clamping assembly, and then start the left and right moving assembly to drive the lifting assembly to move left and right reciprocally so that the bottom surface of the luggage and the top surface of the lowermost friction plate rub against each other, and then...

[0021] S4: After the friction test on one side is completed, start the lifting component to drive the luggage case to move upward away from the lowermost friction plate. Then, the staff rotates the luggage case so that different sides of the luggage case can all undergo friction tests with the lowermost friction plate. Then, take out the luggage case and observe the friction condition to determine whether the wear resistance of the luggage case is qualified;

[0022] S5: Then start the rotating component to drive the rotating box to rotate clockwise by a certain angle until another friction plate is located directly below the luggage case. Then repeat the above steps so that all sides of another new luggage case can undergo friction tests with the adjusted friction plate;

[0023] S6: Repeat step S5 until each friction plate participates in the wear resistance test. In this way, the wear resistance of the luggage case can be comprehensively evaluated for qualification.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] The present invention clamps the luggage case through the clamping component, then uses the lifting component to push the lower side of the luggage case against the top surface of the lowermost friction plate. Then, the left - right moving component drives the luggage case to move left and right reciprocally so that the bottom surface of the luggage case and the friction plate undergo friction to complete the wear resistance test. At the same time, the rotating component drives the rotating box to rotate, enabling multiple friction plates made of different materials to all participate in the test work. Thus, the wear resistance of the outer side of the luggage case can be tested more comprehensively, effectively improving the test accuracy and reliability of the test equipment.

[0049] Specifically, it can more fully and thoroughly test the wear resistance of the outer layer of the luggage, greatly improving the testing accuracy and reliability of the testing equipment.

[0050] Refer to Figures 7-9 , the auxiliary detection component 7 includes multiple groups of receiving cavities 71 that are annularly opened at equal angles on the adjacent sides of multiple friction plates 4. Each group of multiple receiving cavities 71 is equidistantly distributed from front to back. A plurality of groups of friction blocks 72 are annularly and equiangularly movably connected inside the multiple groups of receiving cavities 71. Each group of friction blocks 72 is composed of a row of friction blocks 72. The material of each group of multiple rows of friction blocks 72 is the same as that of the friction plate 4 where it is located. The cross-sectional shapes of the sides of each row of multiple friction blocks 72 close to the axis of the transfer box 3 are different.

[0054] Participate Figure 1 And Figure 2 , the jacking unit 735 includes a fourth electric push rod 7351 on the top of the base 1. A push block 7352 is fixedly connected to the output end of the fourth electric push rod 7351.

[0056] Refer to Figure 1 And Figure 2, the number of the fourth electric push rods 7351 is multiple groups, the number of each group of the fourth electric push rods 7351 is equal to the number of rows of each group of friction blocks 72 and they are respectively located directly below the bottommost group of multi-row friction blocks 72.

[0058] A test method includes the following steps:

[0059] S1: Open the door of the rotating box 3 and place the luggage to be detected at the clamping position of the clamping assembly 6;

[0060] S2: Start the lifting assembly 8 to drive the clamping assembly 6 to move downward to a suitable height, and then start the clamping assembly 6 to clamp the luggage;

[0061] S3: Start the lifting assembly 8 to push the bottom surface of the luggage downward against the top surface of the lowermost friction plate 4 through the clamping assembly 6, and then start the left and right moving assembly 5 to drive the lifting assembly 8 to reciprocate left and right so that the bottom surface of the luggage and the top surface of the lowermost friction plate 4 are rubbed, and then...

[0062] S4: After the friction test of one side is completed, start the lifting assembly 8 to drive the luggage to move upward away from the lowermost friction plate 4, and then the staff rotates the luggage so that different sides of the luggage can all be rubbed with the lowermost friction plate 4, and then take out the luggage to observe the friction situation to determine whether the wear resistance of the luggage is qualified;

[0063] S5: Then start the rotating assembly 31 to drive the rotating box 3 to rotate clockwise by a certain angle until another friction plate 4 is located directly below the luggage, and then repeat the above steps so that all sides of another new luggage can be rubbed with the adjusted friction plate 4;

[0064] S6: Repeat step S5 until each friction plate 4 participates in the wear resistance test, so as to comprehensively evaluate whether the wear resistance of the luggage is qualified.

[0065] Working principle: During the test, open the door of the rotating box 3 and place the luggage to be tested at the clamping position of the clamping assembly 6. Start the third electric push rod to drive the clamping assembly 6 to move downward to an appropriate height. Then start two first electric push rods 62 to push two clamping plates 64 towards each other until the luggage is clamped.

[0066] Then start the third electric push rod to push the bottom surface of the luggage downward against the top surface of the lowermost friction plate 4 through the clamping assembly 6. Then start the left and right moving assembly 5 to drive the clamping assembly 6 to reciprocate left and right so that the bottom surface of the luggage and the top surface of the lowermost friction plate 4 are rubbed against each other to complete the wear resistance test operation of this side.

[0067] At the same time, two second electric push rods 65 can be started to extend and contract respectively, which can drive two clamping plates 64 to rotate in opposite directions. Then, in cooperation with two first electric push rods 62 to push two clamping plates 64 to clamp the luggage, so that the luggage can be swung on the vertical plane, so that the edges and corners of the luggage can also be rubbed against the friction plate 4, so as to more fully and comprehensively test the wear resistance of the outer layer of the luggage, effectively improving the test reliability of the test equipment.

[0068] After the friction test of one side is completed, start the third electric push rod to drive the luggage to move upward away from the lowermost friction plate 4. Then start the first motor 91 to drive the rotating plate 92 to rotate, and the rotating plate 92 drives the luggage to rotate so that different sides of the luggage can be rubbed against the lowermost friction plate 4. Then take out the luggage and observe the friction condition to determine whether the wear resistance of the luggage is qualified.

[0069] Then start the rotating assembly 31 to drive the rotating box 3 to rotate clockwise by a certain angle until another friction plate 4 is located directly below the luggage. Then repeat the above steps so that all sides of another new luggage can be rubbed against the adjusted friction plate 4.

[0070] Repeat the above steps until each friction plate 4 participates in the wear resistance test, so as to comprehensively evaluate whether the wear resistance of the luggage is qualified.

[0071] And when performing a local wear resistance test on each side of the outer layer of the luggage, the fourth electric push rod 7351 can be started to intermittently extend and contract, so as to cooperate with the rotation of the rotating box 3 to enable each friction block 72 to have the opportunity to rub against the outer layer of the luggage, so that different friction test schemes can be flexibly designed according to the concave and convex shapes of each side of the outer layer of the luggage, effectively improving the wear resistance test accuracy and reliability of the test equipment.

[0072] Meanwhile, the fifth electric push rod 7354 can be activated to push the lower sides of the top rods 733 at the bottom ends of different groups of the fourth electric push rods 7351 to the lower sides. In this way, according to different telescopic schemes of multiple groups of the fourth electric push rods 7351 preset in advance, the same positions on the outer layer of the luggage can receive different magnitudes of frictional forces from the friction blocks 72. Thus, according to the preset friction test scheme, each friction block 72 can accurately rub against the designated positions on the outer layer of the luggage with different extrusion forces, so that the test equipment can have more diverse wear resistance performance test schemes. In this way, the accuracy and practicality of the wear resistance performance test can be further improved.
