Description

Technical Field

[0001] This utility model relates to the field of fatigue testing technology for luggage handles, and more specifically, it relates to a fatigue testing machine for luggage handles. Background Technology

[0002] Luggage handles feature a retractable design, allowing users to easily drag suitcases, reducing the burden of carrying them by hand and providing a convenient way to carry them. The handles are typically made of high-strength materials, possessing excellent load-bearing capacity and durability, ensuring stable and reliable operation in various usage environments.

[0003] To ensure that the luggage handle does not break or deform during repeated extension and retraction and use, and to guarantee long-term stability and reliability, improve user experience and product lifespan, the luggage handle needs to undergo fatigue resistance testing before leaving the factory.

[0004] A Chinese patent document with authorization announcement number CN220932595U discloses a fatigue testing machine for luggage pull rods. When testing luggage pull rods, it is necessary to manually place the luggage to be tested on the base, and after the test is completed, it is also necessary to manually remove it for unloading. Moreover, unloading and loading cannot be carried out at the same time, which affects the efficiency of luggage pull rod fatigue testing.

[0005] Furthermore, the above solution only uses a hook to pull the handle of the bag. However, during the fatigue test of the handle, the handle needs to be repeatedly raised and lowered. While the hook can flexibly pull the handle upwards, it may detach from the handle when pulling downwards, affecting the test results. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the problems existing in the prior art, this utility model provides a fatigue testing machine for luggage pull rods, thereby solving the technical problems mentioned in the background art regarding the poor testing efficiency and poor results of the existing fatigue testing machines for luggage pull rods.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A fatigue testing machine for luggage pull rods includes a conveyor frame, a conveying assembly on the conveyor frame, a support frame on the conveyor frame, two first electric push rods symmetrically arranged on the bottom side of the support frame, a side clamping plate at the output end of the first electric push rod, two driving blocks symmetrically arranged on the top inside of the support frame, a synchronous opposing movement assembly between the two driving blocks and the support frame, a second electric push rod at the bottom end of the driving block, a top pressure plate at the top end of the second electric push rod, a third electric push rod at the rear of the support frame, a connecting frame at the bottom end of the third electric push rod, and a handle clamping assembly on the connecting frame.

[0011] The present invention is further configured such that the handle clamping assembly includes a bottom lifting frame, the bottom lifting frame is disposed at the bottom end of the connecting frame, and a top pressing assembly is disposed above the bottom lifting frame.

[0012] The present invention is further configured such that the top pressing assembly includes a fourth electric push rod, which is disposed at the top of the connecting frame. A top pressing frame is disposed at the bottom of the fourth electric push rod, and a button pressing block is disposed at the bottom of the top pressing frame. The top pressing frame is lowered by controlling the fourth electric push rod, so that the top pressing frame presses and fixes itself to the bottom of the top handle of the luggage pull rod, and at the same time, the button pressing block presses against the button on the handle, thereby allowing the pull rod to extend and retract freely. The top pressing frame and the bottom lifting frame cooperate to control the reciprocating extension and retraction detection of the pull rod.

[0013] The present invention is further provided with anti-slip pads on the side clamping plate, the top pressure plate, the bottom lifting bracket and the top clamping bracket. The anti-slip pads can improve the surface anti-slip effect of the side clamping plate, the top pressure plate, the bottom lifting bracket and the top clamping bracket, thereby improving the clamping stability during the test of the luggage handle.

[0014] The present invention is further configured such that the conveying assembly includes conveying rollers, two sets of conveying rollers are symmetrically arranged on the conveying frame, a conveyor belt is arranged between the two sets of conveying rollers, and a conveying motor is arranged on the conveying frame in conjunction with the conveyor belt. When the conveying motor is started, the conveying rollers are rotated by the conveying motor, thereby controlling the conveyor belt to convey the bags.

[0015] The present invention is further configured such that a support plate is provided on the conveyor frame, and the upper surface of the support plate is slidably attached to the bottom of the upper belt surface of the conveyor belt. When the bag is being inspected, it is positioned on the support plate. The support plate can improve the load-bearing capacity of the conveyor belt during bag inspection and enhance the stability of bag inspection.

[0016] This invention is further configured such that the synchronous opposing movement assembly includes a bidirectional screw, which is rotatably mounted on a support frame via bearings. A drive motor is mounted on the support frame in conjunction with the bidirectional screw. The drive block and the bidirectional screw are threadedly engaged. During the process of pressing the top of the luggage, the drive motor can be activated to control the rotation of the bidirectional screw. Through the threaded engagement between the bidirectional screw and the drive block, and the sliding limit relationship between the drive block and the limit rod, the two sets of drive blocks can move synchronously inward or outward. The movement of the drive blocks can control the movement of the second electric push rod, which in turn controls the movement of the top pressure plate. This allows for adjustment of the distance between the two sets of top pressure plates, enabling flexible adjustment of the pressing position of the top pressure plate according to the width of different luggage models, thus improving the flexibility and stability of the pressing process during luggage inspection.

[0017] The present invention is further configured such that a limiting rod is provided on the support frame, and the driving block is slidably sleeved on the limiting rod. The setting of the limiting rod can restrict the rotation and movement of the driving block, thereby improving the movement stability of the driving block.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a fatigue testing machine for luggage pull rods, which has the following beneficial effects:

[0020] 1. This utility model sets up a conveyor frame with a conveyor assembly on it. The conveyor assembly includes cooperating conveyor rollers, a conveyor motor, and a conveyor belt. When conducting fatigue testing on luggage handles, the luggage to be tested is placed on the conveyor belt, the motor is started, and the motor controls the movement of the conveyor belt to move the luggage. This can be combined with existing visual tracking cameras, infrared detectors, and other related detection and positioning equipment to control the movement of the luggage to the detection position and then stop. The above-mentioned related applications are existing known technologies and will not be elaborated on in this utility model. After the luggage is transported to the detection position for testing, the conveyor belt can continue to be controlled to move, thereby realizing the unloading of the luggage after the testing is completed. This improves the efficiency of luggage testing and reduces the time wasted on loading and unloading during the fatigue testing of luggage handles.

[0021] 2. This utility model sets up a support frame, on which a first electric push rod and side clamps are installed to cooperate with each other. After the bag is transported to the testing position by the conveyor belt and stops, the first electric push rod is activated. The first electric push rod can control the movement of the side clamps. The cooperation of the two sets of side clamps achieves clamping and fixing of the side of the bag to be tested. At the same time, the second electric push rod is activated. The second electric push rod controls the top pressure plate to descend, so that the top pressure plate presses and fixes the top of the bag on both sides of the pull rod. This achieves the pressing and fixing of the top of the bag during the pull rod fatigue test. Thus, the cooperation of the top pressure plate and the side clamps achieves stable clamping of the bag pull rod during the fatigue test.

[0022] 3. This utility model incorporates a handle clamping assembly, which includes a bottom lifting frame and a top pressing frame that cooperate with each other. By controlling the lifting and lowering of the connecting frame via a third electric push rod, the bottom lifting frame can be positioned inside the handle of the bag to be tested as the bag moves on the conveyor belt. This positions the handle between the top pressing frame and the bottom lifting frame. After the bag is clamped and fixed, the third electric push rod is controlled to raise the connecting frame, which in turn raises the bottom lifting frame, bringing its bottom end into contact with the bottom of the top handle of the bag handle. Simultaneously, a fourth electric push rod controls the lowering of the top pressing frame, pressing it firmly against the bottom end of the top handle of the bag handle. This also presses the button block against the button on the handle, allowing the handle to extend and retract freely. The third electric push rod is then controlled to reciprocate, causing the bottom lifting frame and the top pressing frame to work together to reciprocate the bag handle, thus achieving the fatigue resistance test of the bag handle.

[0040] In summary:

[0041] This utility model sets up a conveyor frame 1, on which a conveyor assembly is set. The conveyor assembly includes a conveyor roller 15, a conveyor motor 17, and a conveyor belt 16 that cooperate with each other. When conducting fatigue resistance testing of luggage handles, the luggage to be tested is placed on the conveyor belt 16, the motor is started, and the motor controls the operation of the conveyor belt 16 to realize the transfer of luggage. Here, it can be used in conjunction with existing visual tracking cameras, infrared detectors, and other related detection and positioning equipment to control the movement of luggage to the detection position and then stop. The above-mentioned related applications are existing known technologies and will not be described in detail in this utility model. After the luggage is transported to the detection position for testing, the conveyor belt 16 can continue to be controlled to move, thereby realizing the unloading of luggage after the testing is completed, thus improving the efficiency of luggage testing and reducing the time wasted on loading and unloading luggage during the fatigue resistance test of handles.

[0042] This utility model sets up a support frame 2, on which a first electric push rod 3 and a side clamping plate 4 are installed. After the bag is transported to the testing position by the conveyor belt 16 and stops, the first electric push rod 3 is activated. The first electric push rod 3 can control the movement of the side clamping plate 4. The two sets of side clamping plates work together to clamp and fix the side of the bag to be tested. At the same time, the second electric push rod 6 is activated. The second electric push rod 6 controls the top pressure plate 7 to descend, so that the top pressure plate 7 presses and fixes the top of the bag on both sides of the pull rod. This achieves the pressing and fixing of the top of the bag during the pull rod fatigue test. Thus, the cooperation of the top pressure plate 7 and the side clamping plate 4 achieves stable clamping of the bag pull rod during the fatigue test.

[0043] During this process, the drive motor 20 can be started to control the rotation of the bidirectional screw 19. Through the threaded engagement between the bidirectional screw 19 and the drive block 5, and the sliding limit relationship between the drive block 5 and the limit rod 21, the two sets of drive blocks 5 can move inward or outward synchronously. The movement of the drive block 5 can control the movement of the second electric push rod 6, and the movement of the second electric push rod 6 can control the movement of the top pressure plate 7, thereby adjusting the distance between the two sets of top pressure plates 7. This allows for flexible adjustment of the pressing position of the top pressure plate 7 according to the width of different models of suitcases, improving the flexibility and stability of the pressing during the inspection of the suitcase.

[0044] In this utility model, a handle clamping assembly is provided, which includes a bottom lifting frame 10 and a top pressing frame 12 that cooperate with each other. In this way, the connecting frame 9 is raised and lowered by the third electric push rod 8, so that when the bag moves on the conveyor belt 16, the bottom lifting frame 10 can be located inside the bag handle to be tested, so that the handle of the handle is located between the top pressing frame 12 and the bottom lifting frame 10. After the bag is clamped and fixed, the third electric push rod 8 is controlled to drive the connecting frame 9 to rise, and the connecting frame 9 drives the bottom lifting frame 10 to rise, so that the bottom end of the bottom lifting frame 10 is in contact with the bottom of the top handle of the bag handle.

[0045] At the same time, the top pressing frame 12 is lowered by the fourth electric push rod 11, so that the top pressing frame 12 is pressed and fixed to the bottom end of the top handle of the luggage pull rod, and the button pressing block 13 is pressed on the button on the handle, so that the pull rod can be freely extended and retracted.

[0046] Then, the third electric push rod 8 is controlled to reciprocate up and down, so that the bottom lifting frame 10 and the top pressing frame 12 work together to drive the luggage handle to reciprocate up and down, thus realizing the fatigue resistance test of the luggage handle;

[0047] After the test is completed, the restrictions on the handle of the bag pull rod by the bottom lifting frame 10 and the top pressing frame 12 are released. The conveyor belt 16 can be controlled to move back a suitable distance so that the pull rod is disengaged from the bottom lifting frame 10. Then, the bottom lifting frame 10 is controlled to rise and the bag that has been tested is unloaded by the conveyor belt 16.
