Description

Technical Field

[0001] The present invention relates to the technical field of luggage detection, and particularly to an easy-to-position luggage walking bump and wear test device. Background Art

[0002] The luggage walking bump and wear test is a kind of test method used to detect the abrasion resistance and structural strength of suitcases and travel bags with wheels during walking use.

[0003] In the current market, the design standards and technical parameters of luggage walking bump and wear testing machines have been very mature. For example, according to the design standard QB / T2920-2010, the belt circumference of the testing machine is 380 cm and the width is 76 cm, which can simulate the actual use conditions of boxes of different sizes. The technical parameters show that the test speed can be adjusted between 0 and 5 km / h, the time can be set between 0 and 999.9 hours, and it has a power failure memory function to ensure the integrity and accuracy of data during the test.

[0004] Currently, the bump plates on the conveyor belt during the experiment are arranged in two rows at evenly spaced intervals. This design is to simulate the bump situations that luggage may encounter during actual use and ensure the accuracy and reliability of the test. However, in actual situations, the bump situations experienced by the wheels at the bottom of the luggage are different, so there are defects in the experiment. Therefore, the present invention provides an easy-to-position luggage walking bump and wear test device. Summary of the Invention

[0005] In view of the above deficiencies in the prior art, the present invention provides an easy-to-position luggage walking bump and wear test device, which can adjust the positions of the two rows of bump plates on the conveyor belt so that the two rows of bump plates can be flush or asymmetric, enabling the luggage to be tested in two environments.

[0006] The present invention provides the following technical solution: An easy-to-position luggage walking bump and wear test device, including a base and a bump running belt installed inside the base;

[0007] The bump running belt includes two adjusting rollers, and two conveyor belts are driven on the two adjusting rollers. Bump plates for the luggage to walk and bump are distributed on both conveyor belts, and the bump plates on the two conveyor belts are symmetric with each other. The luggage straddles the two conveyor belts. Both ends of the two adjusting rollers are provided with frames, and the two frames are installed on both sides of the inner wall of the base;

[0008] The adjusting roller is driven by a transmission device. When the transmission device drives the adjusting roller to rotate clockwise, the two transmission belts rotate synchronously, and the rollers distributed on the left and right sides of the luggage can contact the bump board at the same time; when the transmission device drives the adjusting roller to rotate counterclockwise, one transmission belt does not move, and the other transmission belt drives reversely. After the bump boards on the two transmission belts are staggered, when the transmission device rotates clockwise again, the rollers distributed on the left and right sides of the luggage contact the bump board alternately front and back;

[0009] A rectangular seat is installed on the base, and two walking rollers are arranged inside the rectangular seat. The positions of the two walking rollers in the rectangular seat are adjusted by a driving structure, so that the two walking rollers can be hidden at both ends of the rectangular seat, and the bump running belt conducts a bump test on the luggage. When the two walking rollers are adjusted onto the bump running belt, the luggage conducts a wear test on the walking rollers;

[0010] A rectangular plate is installed at the top of the rectangular seat. A movable frame that can move back and forth is arranged at the front end of the rectangular plate, and a lifting structure for hanging and taking the handle of the luggage is arranged on the movable frame. Two support frames that can slide and are used to limit the position of the luggage are arranged on the rectangular plate.

[0011] Preferably, a support beam is arranged between the two side frames, and a pedal for supporting the transmission belt is installed on the support beam, and the transmission belt during transmission can slide on the pedal.

[0012] Preferably, baffles for blocking the edges of the transmission belts are installed on both of the two side frames.

[0013] Preferably, the adjusting roller includes a connecting shaft installed between the two side frames. A belt pulley A and a belt pulley B that can rotate are arranged on the connecting shaft. A helical tooth groove is arranged at one end of the belt pulley A. One-way wheels are arranged at both ends of the belt pulley B. The belt pulley A drives the one-way wheel on the belt pulley B to rotate unidirectionally through the helical tooth groove. A positioning wheel is installed on the connecting shaft, and a helical tooth groove in contact with the one-way wheel is also arranged on one side of the positioning wheel, so that the belt pulley A rotates clockwise to drive the belt pulley B to rotate synchronously. When the belt pulley A rotates counterclockwise, the belt pulley B stops moving.

[0014] Preferably, protrusions for preventing the transmission belt from falling off are arranged at both ends of the belt pulley A and the belt pulley B.

[0015] Preferably, the one-way wheel includes a round wheel installed on the belt pulley B. Grooves are arranged at intervals on the edge of the round wheel, and a helical tooth block is hinged inside the groove. A return spring for ejecting the helical tooth block is installed inside the groove, and the helical tooth block on the round wheel can slide unidirectionally along the direction of the helical teeth in the helical tooth groove.

[0016] Preferably, the driving structure includes a guide post installed in a rectangular seat, and two slidable movable seats are arranged on the guide post, and the walking rollers are arranged on the movable seats. A bevel gears are installed at the shaft ends of the two walking rollers, and rotatable B bevel gears are arranged on the two movable seats. The A bevel gears are meshed with the B bevel gears. Spline shafts are arranged in the middle of the two B bevel gears, and the two B bevel gears slide on the spline shafts. The two ends of the spline shaft are installed on the inner wall of the rectangular seat through shaft seats, and the spline shaft is driven by a motor, so that the motor drives the spline shaft to rotate. Under the meshing of the A bevel gears and the B bevel gears, the walking rollers are driven to rotate.

[0017] Preferably, two hydraulic cylinders for pushing the movable seats to move are arranged inside the rectangular seat, so that the B bevel gears on the movable seats slide on the spline shafts to adjust the positions.

[0018] Preferably, the lifting structure includes a support rod that can slide up and down in a movable frame. A rotatable connecting pipe is arranged on the support rod. An L-shaped block is arranged on the connecting pipe, and two slidable pull rods are arranged on the L-shaped block. A positioning hook for hanging a luggage case is arranged at the bottom end of the pull rod, a convex cap is installed at the top end of the pull rod, and a spring is arranged on the pull rod between the L-shaped block and the convex cap.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1). With the design of two conveyor belts, by adjusting the symmetry relationship of the bump plates on the conveyor belts, the luggage case can be straddled on the two conveyor belts for testing, which can better simulate diverse and irregular road conditions in real life. This design makes the test closer to the actual use scenario in real life, so as to more accurately predict the performance and durability of the luggage case in actual use;

[0021] (2). The asymmetric configuration of the bump plates creates different test scenarios, which helps to detect the durability of the luggage case under different conditions. This comprehensive test method improves the reliability of the experimental results and provides more valuable feedback for product design and quality control;

[0022] (3). By integrating the walking wheels and the conveyor belts into one device, two experiments of bumping and abrasion of the luggage case can be completed, which can simulate the walking bumping and abrasion conditions of the luggage case during actual use. The structure is compact and the floor area is small, which is suitable for use in environments with limited space such as laboratories or production workshops;

[0023] (4). The design of the lifting structure and the support frame is used to test the luggage case, which facilitates the positioning of the luggage case and increases the applicability and flexibility of the device. It can simulate the left and right shaking during the bumping of the luggage case. This design enables the device to meet the test requirements of various specifications and types of luggage cases on the market. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0033] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present disclosure with reference to the accompanying drawings of the embodiments of the present disclosure. In order to keep the following description of the embodiments of the present disclosure clear and concise, the detailed descriptions of known functions and known components are omitted in the present disclosure to avoid unnecessarily confusing the concepts of the present invention.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3, An easily positioned luggage walking bump and wear test device, including a base 1 and a bump running belt 2 installed inside the base 1. The bump running belt 2 includes two adjusting rollers 21, and two transmission belts 22 are driven on the two adjusting rollers 21. Bump plates 23 for the luggage to walk bumpily are distributed on both transmission belts 22, and the bump plates 23 on the two transmission belts 22 are symmetrical to each other. The luggage straddles the two transmission belts 22. Both ends of the two adjusting rollers 21 are provided with frames 24, and the two frames 24 are installed on both sides of the inner wall of the base 1. A support beam 25 is provided between the two frames 24, and a pedal 26 for supporting the transmission belt 22 is installed on the support beam 25, and the transmission belt 22 during transmission can slide on the pedal 26. Baffles 27 for blocking the edges of the transmission belt 22 are installed on both of the two frames 24.

[0035] The two adjusting rollers 21 are used as driving rollers to drive the two transmission belts 22 for transmission, so that the two transmission belts 22 slide on the pedal 26. The two transmission belts 22 are supported by the pedal 26, so that the luggage can perform a bump and wear test on the two transmission belts 22.

[0036] The adjusting roller 21 is driven by a transmission device. When the transmission device drives the adjusting roller 21 to rotate clockwise, the two transmission belts 22 rotate synchronously. In this way, the rollers distributed on the left and right sides of the bottom of the luggage, although on the two transmission belts 22, can simultaneously contact the bump plates 23, causing the rollers at the bottom of the luggage to bump simultaneously. At this time, the bump plates 23 on the two transmission belts 22 are symmetrical left and right, so as to detect the quality of the luggage.

[0037] When the transmission device drives the adjusting roller 21 to rotate counterclockwise, one transmission belt 22 does not move, and the other transmission belt 22 drives reversely. After the bump plates 23 on the two transmission belts 22 are staggered, when the transmission device rotates clockwise again, the rollers distributed on the left and right sides of the bottom of the luggage contact the bump plates 23 alternately front and back. At this time, the bump plates 23 on the two transmission belts 22 are asymmetrical and staggered. In this way, the rollers distributed on the left and right sides of the bottom of the luggage contact the bump plates 23 at different positions, simulating that the luggage may move on various road surfaces with different flatness. Therefore, the bump plates 23 on the two transmission belts 22 with asymmetric settings can better simulate these diverse road conditions, making the test results closer to the actual situation.

[0038] Refer to Figure 4 and Figure 5, the adjusting roller 21 includes a connecting shaft 211 installed between two side frames 24, and rotatable A belt roller 212 and B belt roller 213 are provided on the connecting shaft 211. One end of the A belt roller 212 is provided with an inclined tooth groove 214. One-way wheels 215 are provided at both ends of the B belt roller 213, and the A belt roller 212 drives the one-way wheels 215 on the B belt roller 213 to rotate unidirectionally through the inclined tooth groove 214. A positioning wheel 216 is installed on the connecting shaft 211, and an inclined tooth groove 214 in contact with the one-way wheel 215 is also provided on one side of the positioning wheel 216.

[0039] When the A belt roller 212 rotates clockwise to drive the B belt roller 213 to rotate synchronously, the inclined tooth groove 214 on the A belt roller 212 drives the one-way wheel 215 at one end of the B belt roller 213 to rotate, while the one-way wheel 215 at the other end of the B belt roller 213 idles in the inclined tooth groove 214 of the positioning wheel 216. In this way, the A belt roller 212 and the B belt roller 213 rotate synchronously clockwise, enabling the two transmission belts 22 to be synchronously driven to detect the bumps during the walking of the luggage.

[0040] When the A belt roller 212 rotates counterclockwise, the inclined tooth groove 214 on the A belt roller 212 idles on the one-way wheel 215 at one end of the B belt roller 213, while the inclined tooth groove 214 of the positioning wheel 216 catches the one-way wheel 215 at the other end of the B belt roller 213 to prevent the B belt roller 213 from rotating counterclockwise. Therefore, the B belt roller 213 stops moving. In this way, the A belt roller 212 rotates counterclockwise, driving one transmission belt 22 to drive reversely, causing the bump plates 23 on the two transmission belts 22 to stagger and separate. In this way, the position of the bump plates 23 on the transmission belt 22 is adjusted. Then the A belt roller 212 rotates clockwise again. When detecting the bumps during the walking of the luggage, the road surface is simulated through the transmission belts 22 with different distributed bump plates 23.

[0041] Protrusions for preventing the transmission belts 22 from falling off are provided at both ends of the A belt roller 212 and the B belt roller 213. In this way, the two transmission belts 22 are driven on the A belt roller 212 and the B belt roller 213, and are not easily fallen off, and the two transmission belts 22 are prevented from touching each other.

[0042] The adjusting roller 21 is driven by a transmission device, and the transmission device is driven by a belt pulley and a belt, and is driven by a motor. The belt pulley is installed on the A belt roller 212, and the motor can be installed on the support beam 25. The motor drives the belt pulley thereon to rotate, and drives the belt pulley on the A belt roller 212 to rotate under the belt drive, as Figure 3 .

[0043] Refer to Figure 6, the one-way wheel 215 includes a round wheel 217 mounted on the B belt roller 213. Grooves are provided at intervals on the edge of the round wheel 217, and a bevel gear block 218 is hinged inside the groove. A return spring for ejecting the bevel gear block 218 is installed inside the groove. When the bevel gear block 218 on the round wheel 217 can slide unidirectionally along the bevel direction of the bevel gear groove 214, when the bevel gear block 218 on the round wheel 217 is in the reverse direction, the bevel gear block 218 is stuck in the bevel gear groove 214 and cannot continue to rotate.

[0044] Refer to Figure 1 , a rectangular seat 3 is installed on the base 1, and two walking rollers 4 are provided inside the rectangular seat 3. The positions of the two walking rollers 4 in the rectangular seat 3 are adjusted by a driving structure 9, so that the two walking rollers 4 can be hidden at both ends of the rectangular seat 3. In this way, there is no obstruction on the bumpy running belt 2, and the bumpy running belt 2 can conduct a bump test on the luggage. When the two walking rollers 4 are adjusted onto the bumpy running belt 2, the luggage conducts a wear test on the walking rollers 4.

[0045] Refer to Figure 7 , the driving structure 9 includes a guide post 91 installed inside the rectangular seat 3, and two slidable movable seats 92 are provided on the guide post 91. The walking roller 4 is arranged on the movable seat 92. A bevel gear 93 is installed at the shaft ends of the two walking rollers 4, and a rotatable bevel gear 94 is provided on each of the two movable seats 92. The bevel gear 93 meshes with the bevel gear 94. A spline shaft 95 is provided in the middle of the two bevel gears 94, and the two bevel gears 94 slide on the spline shaft 95. The two ends of the spline shaft 95 are installed on the inner wall of the rectangular seat 3 through shaft seats, and the spline shaft 95 is driven by a motor. Two hydraulic cylinders 96 for pushing the movable seat 92 to move are provided inside the rectangular seat 3, so that the bevel gear 94 on the movable seat 92 slides on the spline shaft 95 to adjust the position.

[0046] The hydraulic cylinder 96 is used to push the movable seat 92 to slide on the guide post 91 and the spline shaft 95 to adjust the positions of the two movable seats 92. Then the motor drives the spline shaft 95 to rotate. Under the meshing of the bevel gear 93 and the bevel gear 94, the walking roller 4 is driven to rotate. In this way, the walking wear of the luggage can be detected. Compared with the transmission belt 22 that can only detect the bumpy situation of the luggage, the walking roller 4 can detect the wear of the luggage rollers. The two cooperate to detect the two experimental processes of the bump wear of the luggage.

[0047] Refer to Figure 1 , a rectangular plate 5 is installed at the top of the rectangular seat 3. A movable frame 6 that can move back and forth is provided at the front end of the rectangular plate 5, and a lifting structure 7 for hanging and taking the handle of the luggage is provided on the movable frame 6. The position of the movable frame 6 is adjusted back and forth, and the lifting structure 7 is used to hook the handle of the luggage to tilt the luggage, so that the rollers at the front end of the luggage can conduct a walking test on the walking roller 4 or the transmission belt 22.

[0048] Two support frames 8 that can slide and are used to limit the luggage are provided on the rectangular plate 5. Adjust the positions of the two support frames 8 to position the luggage so that the luggage can be walking-tested on the two walking rollers 4 or the conveyor belt 22 in a vertical state.

[0049] Refer to Figure 8 , the lifting structure 7 includes a support rod 71 that can slide up and down in the movable frame 6. A rotatable connecting pipe 72 is provided on the support rod 71. An L-shaped block 73 is provided on the connecting pipe 72, and two slidable pull rods 74 are provided on the L-shaped block 73. A positioning hook 75 for hanging the luggage is provided at the bottom end of the pull rod 74. A convex cap is installed at the top end of the pull rod 74. A spring 76 is provided on the pull rod 74 between the L-shaped block 73 and the convex cap.

[0050] When the luggage is walking on the walking roller 4 or the conveyor belt 22 and encounters the bump plate 23, the luggage will shake left and right. To create this phenomenon, the lifting structure 7 is used to simulate the walking situation of the luggage. When the bottom rollers of the luggage are jolted during walking, the luggage receives a backward pulling force, causing the handle on the luggage to drive the positioning hook 75 to move backward. In this way, the positioning hook 75 pulls the pull rod 74 to move and reset under the action of the spring 76, so that when the luggage is walking on the walking roller 4 or the conveyor belt 22, it shakes left and right, and the forces on the left and right sides of the handle on the luggage are also different. The connecting pipe 72 can rotate. In this way, when the positioning hook 75 hooks the handle on the luggage, it can provide a good positioning effect and facilitate the positioning of the luggage. When the forces on the left and right sides of the handle on the luggage are applied, it will pull the positioning hook 75, causing the pull rod 74 to move and then reset under the action of the spring 76. In this way, the luggage shakes left and right during the walking test, not limited to the shaking caused by bumps. If the positioning hook 75 cannot position the handle of the luggage, the positioning hook 75 can be replaced with a positioning clip to prevent the handle of the luggage from detaching.

[0051] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
