[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3, an embodiment of the utility model is provided: a telescopic dog traction rope testing machine, comprising a base 1 and a transmission belt 10, a C-shaped groove 3 is opened on the right side of the top of the base 1, a first bidirectional screw rod 4 is rotatably connected to the right side of the front end of the base 1, and the rear end of the first bidirectional screw rod 4 passes through the C-shaped groove 3, and the second bidirectional screw rod 5 is rotatably connected to the inner rear side of the C-shaped groove 3, and the outer wall side of the first bidirectional screw rod 4 and the second bidirectional screw rod 5 is fixedly connected to the second pulley 9, and the inner side of the C-shaped groove 3 is rotatably connected to the movable shaft 7, and the front and rear sides of the movable shaft 7 are fixedly connected to the first pulley 8, and the two first pulleys 8 are respectively connected to the corresponding second pulley 9 through the transmission belt 10. The front and rear sides of the outer walls of the first bidirectional screw rod 4 and the second bidirectional screw rod 5 are threadedly connected with a clamping plate 6, and the adjacent sides of each two clamping plates 6 are provided with a pet traction rope 12, and a detection mechanism 2 is provided on the left side of the top of the base 1, and one side of the plurality of clamping plates 6 is fixedly connected with a rubber pad 11, and the middle and lower parts of the plurality of clamping plates 6 are slidably connected to the inside of the C-shaped groove 3;

[0032] Specifically, when the first bidirectional screw 4 is rotated, the second pulley 9 thereon will rotate easily, and this process is realized through the movable shaft 7, and the corresponding first pulley 8 can also rotate smoothly with the operation of the transmission belt 10. In this way, the movable shaft 7 can be smoothly driven to rotate. During the transmission process, the first pulley 8 on the rear side of the movable shaft 7 can also drive the second pulley 9 on the second bidirectional screw 5 to rotate through the transmission belt 10. This means that the second bidirectional screw 5 can also rotate accordingly, and at this time, the clamping plates 6 on the first bidirectional screw 4 and the second bidirectional screw 5 will magically move to the middle at the same time. The cleverness of this design is that it makes it extremely simple to disassemble and fix the pet traction dog leash 12.

[0033] Reference Figure 1 , Figure 2 and Figure 4The detection mechanism 2 includes a support plate 201, which is fixedly connected to the left side of the top of the base 1. The front and rear ends of the right side of the support plate 201 are fixedly connected with a tension sensor 202. The right side of the tension sensor 202 is fixedly connected with a rope 203. The left side of the middle top of the base 1 is fixedly connected with a double-headed motor 204. The output end of the double-headed motor 204 is fixedly connected with a first rotating rod 205. The outer side of the first rotating rod 205 is fixedly connected with an active bevel gear 206. The front and rear sides of the top of the base 1 are rotatably connected with a rotating shaft 207. A driven bevel gear 208 is fixedly connected to the top of the shaft 207, and the two driven bevel gears 208 are respectively meshed with the corresponding active bevel gears 206. A plurality of movable rods 209 are rotatably connected to the left side of the middle of the top of the base 1. The movable rods 209 and the cylindrical gears 211 are both fixedly connected to the cylindrical gears 211 at the middle and lower parts of the outer sides. The cylindrical gears 211 are meshed with each other. A movable pulley 210 is fixedly connected to the middle and upper parts of the outer sides of the movable rods 209, and one end of the plurality of ropes 203 is respectively fixedly connected to the outer sides of the corresponding movable pulleys 210.

[0034] Specifically, the double-headed motor 204 can drive the first rotating rod 205 to rotate, and can also trigger a series of chain reactions. When the first rotating rod 205 rotates, the active bevel gear 206 on its outer side will also rotate accordingly. This rotating force is transmitted through the meshing of the driven bevel gear 208 and the active bevel gear 206, further driving the rotating shaft 207 to rotate. The rotation of the rotating shaft 207 is not limited to this, it also drives the cylindrical gear 211 meshing with it to rotate. In this process, the movable pulley 210 on the movable rod 209 will also rotate accordingly to wind the rope 203. This series of actions are achieved through precise mechanical design and working principles. It is worth mentioning that one end of the rope 203 is connected to the tension sensor 202. The function of the tension sensor 202 is to measure the traction force. Therefore, we can multiply the data measured by the tension sensor 202 by the number of strands of the rope 203 on both sides wound around the movable pulley 210 to obtain the traction force of the pet traction rope 12 to be measured. When the movable pulley 210 rotates, it will evenly distribute the received traction force to the ropes 203 on both sides. This design greatly reduces the force received by the tension sensor 202, thereby improving the service life of the tension sensor 202.

[0035] Reference Figure 1 and Figure 2 A controller 13 is fixedly connected to the left side of the front end of the base 1, and the controller 13 is electrically connected to the double-headed motor 204. A protective cover 14 is arranged on the outside of the controller 13, and one end of the protective cover 14 is rotatably connected to the front side of the base 1;

[0036] Specifically, the operation of the double-headed motor 204 can be controlled by the controller 13, and the protective cover 14 can protect the controller 13 from being damaged by external factors.

[0037] Reference Figure 2 and Figure 5 The detection mechanism 2 also includes a second rotating rod 212 and an arc-shaped pressing plate 216. The two second rotating rods 212 are respectively fixedly connected to one end of the corresponding first rotating rod 205. The front and rear sides of the plurality of second rotating rods 212 are fixedly connected with a disc 213. A groove 214 is provided on one side of the disc 213. A spring 215 is fixedly connected to the inner bottom of the groove 214. The top ends of the plurality of springs 215 are respectively fixedly connected to the front and rear sides of the bottom of the corresponding arc-shaped pressing plate 216. The front and rear side sizes of the plurality of arc-shaped pressing plates 216 match the internal sizes of the corresponding grooves 214.

[0038] Specifically, first pull the arc pressure plate 216 upwards. This step is to ensure that the subsequent detection process can proceed smoothly. The role of the arc pressure plate 216 is crucial. It will be closely connected with the subsequent operations. After completing the action of pulling the arc pressure plate 216 upwards, the next step is to place one end of the telescopic traction dog rope between the arc pressure plate 216 and the second rotating rod 212. This step is to ensure that the traction dog rope can be stably in the correct position to prevent unnecessary mistakes in subsequent operations. After ensuring that the traction dog rope is correctly placed, the arc pressure plate 216 can be loosened. At this time, the spring 215 will play a role and use its own elastic potential energy to drive the arc pressure plate 216 to rebound. The main purpose of this action is to limit the rope body and ensure that the telescopic traction dog rope will not accidentally fall off during the detection process.

[0039] Working principle: When using the device, first place the pet traction rope 12 between the corresponding clamping plates 6, and then rotate the first bidirectional screw rod 4. At this time, the second pulley 9 on the first bidirectional screw rod 4 will rotate accordingly, and the first pulley 8 corresponding to it on the movable shaft 7 will rotate along with it through the transmission belt 10, thereby driving the movable shaft 7 to rotate. At this time, the first pulley 8 on the rear side of the movable shaft 7 will drive the second pulley 9 on the second bidirectional screw rod 5 to rotate through the transmission belt 10, thereby making the second bidirectional screw rod 5 rotate. At this time, the clamping plates 6 on the first bidirectional screw rod 4 and the second bidirectional screw rod 5 will rotate together. The pet traction rope 12 is limited and fixed by moving it toward the middle at the same time. It is relatively simple to disassemble and fix the telescopic traction dog rope, thereby improving the detection efficiency of the subsequent telescopic traction dog rope and meeting the needs of users. Before performing the detection work, the arc-shaped pressing plate 216 is first pulled upward, and then one end of the telescopic traction dog rope is placed between the arc-shaped pressing plate 216 and the second rotating rod 212, and then the arc-shaped pressing plate 216 is released. At this time, the spring 215 will drive the arc-shaped pressing plate 216 to rebound through its own elastic potential energy to limit and clamp the rope body, so as to prevent the telescopic traction dog rope from accidentally falling off during the detection process. At this time, the double-headed motor 204 can drive the first rotating rod 205 to rotate, and the second rotating rod 212 will rotate accordingly to detect the telescopic traction dog rope. When the first rotating rod 205 rotates, the active bevel gear 206 on its outer side will rotate accordingly. Since the driven bevel gear 208 is meshed with the active bevel gear 206, it will also rotate accordingly. At this time, the rotating shaft 207 will drive the cylindrical gear 211 to rotate, and the cylindrical gear 211 meshed with it will also rotate accordingly. At this time, the movable pulley 210 on the movable rod 209 will rotate accordingly to wind the rope 203. Since one end of the rope 203 is connected to the pulling rod 203, The force sensor 202 is connected, so the data measured by the tension sensor 202 is multiplied by the number of ropes 203 on both sides of the movable pulley 210, which is the traction force of the pet traction rope 12 to be tested. When the movable pulley 210 rotates, the received traction force will be evenly distributed to the ropes 203 on both sides, so that the force received by the tension sensor 202 can be reduced exponentially, thereby increasing the service life of the tension sensor 202. The model of the double-headed motor 204 is 2543N9C2B, and the double-headed motor 204 and the tension sensor 202 are both existing technologies, so they are not described in detail in this article.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
