[0002] Nowadays, pet dogs have become the companion choice for more and more people in urban life. They can bring better improvements to people's lives and relieve loneliness in life. Among them, due to the potential aggressiveness of dogs themselves, according to relevant laws and regulations, when taking dogs out of the house, they should wear dog tags and take measures such as tying dog leashes as required to prevent dogs from injuring people and spreading diseases. Therefore, leashes have become an indispensable accessory for taking dogs out today.

[0003] Among them, since the leash is an important tool for restraining dogs, it should be strength tested before leaving the factory to ensure the strength of the leash and avoid breakage of the leash caused by the dog's sudden charge. To this end, current testing equipment mostly uses a tensile machine to connect the two ends of the leash and complete the test by stretching the two ends. However, the above-mentioned testing device has a large deviation from the actual usage state, and it is difficult to imitate the impact force of a dog's sudden charge, so it needs to be improved.

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are represented by the same reference numerals.

[0028] like Figure 1-5 As shown, a dog traction rope burst test device is used to simulate the test of the dog traction rope 31, including a mounting frame 1, the top of the mounting frame 1 extends outward to form an extension portion 23, the extension portion 23 is provided with a mounting cavity 24, the connecting portion 2 is a rod and is located at the mounting cavity 24, an induction coil 25 is provided in the mounting cavity 24, an induction circuit is provided in the mounting frame 1 and is connected to the induction coil 25 through a wire, a magnet 26 is provided on the connecting portion 2, so that the induction coil 25 is sleeved outside the magnet 26, and a reset spring 27 is also provided on the connecting portion 2, and the two ends of the reset spring 27 are respectively connected to the connecting portion 2 and the mounting cavity 24 to drive the connecting portion 2 to move toward the mounting cavity 24, a connecting rope 3 is provided at the lower end of the connecting portion 2 and the upper end of the traction rope 31 is connected through the connecting rope 3, the connecting rope 3 is made of non-elastic material, and the lower end of the traction rope 31 is connected to a weight block 8.

[0029] During specific use, the weight 8 falls downward under gravity, thereby completing the explosive test of the traction rope 31. At the same time, the falling of the weight 8 can drive the connecting part 2 to move slightly, thereby driving the magnet 26 to move, so that the induction coil 25 generates an induced current, and the induction circuit obtains the size of the impact force based on the induced current.

[0030] Furthermore, in order to improve the stability of the connecting rope 3 during the falling process of the weight 8, a supporting pulley 28 is provided on the mounting frame 1 corresponding to the connecting rope 3. The supporting pulley 28 includes a connecting seat and a pulley, wherein one end of the connecting seat is fixedly connected to the mounting frame 1, and the other end is rotatably connected to the pulley. The connecting rope 3 is constrained by the interference of the pulley to improve the stability of the connecting rope 3.

[0031] Furthermore, a chamber is opened at the bottom of the mounting frame 1, and a control end 11 is formed at one end of the receiving frame 4 and is arranged corresponding to the chamber. Specifically, guide blocks 14 are provided on both sides of the control end 11, and guide grooves 15 are provided on the side walls of the chamber corresponding to the guide blocks 14. The guide blocks 14 on both sides slide and limit the guide grooves 15 on both sides respectively to limit the control end 11 to only slide up and down. Specifically, in this embodiment, the test station 6 and the initial station 7 are respectively located at the upper and lower ends of the guide groove 15.

[0032] Furthermore, the driving device 5 is disposed in the mounting frame 1 and connected to the receiving frame 4 to drive the receiving frame 4 to move up and down, thereby realizing the reciprocating movement of the receiving frame 4 between the testing station 6 and the initial station 7 .

[0033] Specifically, the driving device 5 is a cylinder, a suction cup 13 is provided at the cylinder output end, and a traction disk 12 is provided on the control end 11. When in use, the cylinder output end controls the suction cup 13 to contact with the traction disk 12, and the suction cup 13 and the traction disk 12 are further adsorbed, and the position of the control end 11 is further adjusted by the extension and retraction of the cylinder, thereby realizing the up and down driving of the receiving frame 4.

[0034] At the same time, the adsorption method of the suction cup 13 and the traction plate 12 can provide additional gravity for the receiving frame 4 through the traction plate 12 to accelerate the falling of the receiving frame 4. At the same time, the traction plate 12 can also adjust the overall stress condition of the receiving frame 4 when receiving the weight 8 to increase the service life of the receiving frame 4.

[0035] Since different traction ropes 31 have different lengths, in order to ensure the test effect of different traction ropes 31, an adjusting rope 9 is provided on the weight block 8 and the lower end of the traction rope 31 is connected through the adjusting rope 9. The adjusting rope 9 is specifically a plurality of annular connecting rings 29, and the plurality of connecting rings 29 are sequentially sleeved, and the connecting ring 29 at the end forms an opening 30 for connecting other connecting rings 29 to form an overall annular structure. The operator can adjust the connection position of the opening 30 according to the specific length of the traction rope 31 to ensure that the overall length is within the test range.

[0036] Among them, in order to support the receiving frame 4 and reduce the impact when the receiving frame 4 falls downward, the device also includes an elastic component 10, which can be set on the ground or on an extension surface formed by the bottom of the mounting frame 1 extending outward. In this embodiment, it is preferably the ground. The elastic component 10 can greatly reduce the impact force of the receiving frame 4 to extend the service life of the receiving frame 4.

[0037] Specifically, the elastic component 10 includes a plurality of mounting seats 16 , and a support spring 17 is provided on the top of the mounting seat 16 . When the support spring 17 contacts the supporting frame 4 , a gap 18 is formed between the lower end of the supporting frame 4 and the mounting seat 16 , thereby avoiding rigid contact of the supporting frame 4 .

[0038] Furthermore, when the receiving frame 4 supports the weight block 8, the pressure of the weight block 8 will cause uneven force on the receiving frame 4, which may easily cause the guide block 14 to break. Therefore, in order to improve the overall supporting strength, the guide block 14 extends downward to form an adjusting portion 19, and the adjusting portion 19 is provided with an inclined support rod 20, and the two ends of the support rod 20 are respectively connected to the adjusting portion 19 and the receiving frame 4.

[0039] Due to the support method of the mounting seat 16 and the support spring 17, the support rod 20 can be set at the bottom of the receiving frame 4 without affecting the placement position of the weight 8, thereby greatly expanding the installation range of the support rod 20.

[0040] In order to further improve the force stability of the receiving frame 4 when receiving, a support cavity 21 is opened in the guide groove 15, and an electric telescopic rod 22 is arranged in the support cavity 21. When the receiving frame 4 moves to the testing station 6, the electric telescopic rod 22 extends and contacts with the adjustment part 19 to provide a supporting force in the direction of the weight block 8, thereby further improving the force condition of the receiving frame 4 to ensure that the force of the receiving frame 4 is uniform.

[0041] The implementation principle of the burst test device of a dog traction rope 31 in the embodiment of the present application is as follows: in the initial state, the cylinder extends to drive the suction cup 13 to adsorb and fix with the traction disc 12, and the cylinder retracts to move the receiving frame 4 to the test station 6. At this time, the electric telescopic rod 22 extends to provide additional support force for the adjustment part 19. At the same time, the weight block 8 is located on the receiving frame 4, and the upper end of the traction rope 31 is connected to the connecting rope 3, and the lower end of the traction rope 31 is connected to the adjusting rope 9. The adjusting rope 9 is further adjusted according to the specific length of the traction rope 31, so that the traction rope 31 is in a relaxed state, and the traction rope The overall length of 31 plus the adjusting rope 9 is within the test length range, and the test is further started. The electric telescopic rod 22 retracts to separate from the adjusting part 19 to ensure the smooth falling of the adjusting part 19. At the same time, the suction cup 13 gives up adsorption with the traction plate 12, so that the receiving frame 4 falls to the initial station 7 and is supported by the supporting spring 17. At the same time, the weight block 8 also falls to complete the burst test of the traction rope 31. At the same time, after the weight block 8 falls, a specific impact force can be obtained through the induction coil 25. The operator can repeat the above actions to complete the fatigue test of the traction rope 31.

[0042] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
