[0001] The utility model relates to the technical field of traction devices, and particularly relates to a traction device for pet dogs. Background Art

[0002] A traction device for pet dogs, usually called a leash or dog chain, is an essential equipment when pet dogs go out. The primary function of the leash is to ensure the safety of pet dogs outdoors. Through the leash, the owner can control the movement of the dog, prevent it from getting lost, being involved in traffic accidents or attacked by other animals.

[0003] However, the length of the traditional traction device for pet dogs is fixed, which limits the activity range of pet dogs, has poor flexibility, and the leash is connected to the collar on the pet dog's neck through a buckle, with a tight connection. When an emergency occurs, it is difficult to unfasten, thus there are certain potential safety hazards. In view of the above problems, the inventor proposes a traction device for pet dogs to solve the above problems. Summary of the Utility Model

[0004] In order to solve the problems of the telescopic and automatic unfastening of the traction rope for pet dogs; the purpose of the utility model is to provide a traction device for pet dogs.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: A traction device for pet dogs, including a body, a winding groove is opened inside the body, a rotating rod is rotatably connected inside the winding groove, a clockwork spring is fixedly installed on the outer side of the rotating rod, a traction rope is wound around the outer side of the clockwork spring and inside the winding groove, fixed frames are fixedly connected to both sides of the body, locking mechanisms are arranged inside the fixed frames, the two locking mechanisms are mirror-symmetrically distributed, a through groove is opened on the front side of the body, one end of the traction rope movably passes through the through groove and is fixedly connected to a connecting frame, a collar is arranged on one side of the connecting frame, a clamping mechanism is arranged between the connecting frame and the collar, and a fixed ring is fixedly connected to the side of the body away from the locking mechanism.

[0006] Preferably, the locking mechanism includes a ratchet wheel, the ratchet wheel is rotatably connected to one side of the body and inside the fixed frame, the rotating shaft of the ratchet wheel is fixedly connected to the winding groove, a fixed block is fixedly connected to the side of the fixed frame close to the ratchet wheel, a pawl is rotatably connected to the side of the fixed frame close to the fixed block, the front end of the pawl is movably inserted into the tooth groove of the ratchet wheel, a first spring is fixedly connected between the pawl and the fixed block, unlocking grooves are opened at the tops of the fixed frames, the top end of the pawl movably extends to the outside of the unlocking groove, and the pawl is slidably clamped in the unlocking groove.

[0007] The lock member is a pair of locks, each of which is connected to the control frame by a toothed connection, and the toothed connection member is a pair of locks, each of which is connected to the control frame by a toothed connection.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] 1. By movably inserting the front end of the insertion rod into the slot and inserting the clamping block into the slot, the elastic force of the slot makes the clamping slot and the clamping block more tightly connected, thereby limiting the withdrawal of the insertion rod. When an emergency occurs, by pulling the traction rope with force, the clamping block and the inclined surface of one side of the slot are used to simultaneously push the two clamping blocks away from each other, so that the clamping block is disengaged from the inside of the slot, thereby releasing the restriction on the withdrawal of the insertion rod, making it easier to separate the collar and the traction rope, and further improving the safety of the traction device when in use.

[0010] 2. By moving the pawl on one side and compressing spring 1, the pawl is disengaged from the inside of the ratchet, and the restriction on the rotation of the ratchet in the extension direction is released, so that the traction rope can be pulled out from the inside of the winding groove and the clockwork spring is wound. After stretching to the appropriate position, the pawl is released and the elastic force of spring 1 is used to re-engage the pawl in the slot of the ratchet, thereby restricting the rotation in the extension direction of the corresponding ratchet. When the extension length of the traction rope needs to be shortened, the pawl on the other side is moved to release the restriction on the rotation in the winding direction of the corresponding ratchet, and then the elastic force of the clockwork spring is used to realize automatic winding of the traction rope, which is flexible and convenient to operate.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment: As Figures 1-5 shown, the present utility model provides a traction device for pet dogs, including a body 1. A winding groove 2 is opened inside the body 1. A rotating rod 10 is rotatably connected inside the winding groove 2. A clockwork spring 11 is fixedly installed on the outer side of the rotating rod 10. A traction rope 3 is wound around the outer side of the clockwork spring 11 and inside the winding groove 2. Fixed frames 4 are fixedly connected to both sides of the body 1. Locking mechanisms 5 are arranged inside the fixed frames 4. The two locking mechanisms 5 are mirror-symmetrically distributed. A through groove 6 is opened on the front side of the body 1. One end of the traction rope 3 movably penetrates through the through groove 6 and is fixedly connected to a connecting frame 7. A collar 8 is arranged on one side of the connecting frame 7. A clamping mechanism 9 is arranged between the connecting frame 7 and the collar 8.

[0020] The locking mechanism 5 includes a ratchet 51, which is rotatably connected to one side of the machine body 1 and located inside the fixed frame 4. The rotating shaft of the ratchet 51 is fixedly connected to the winding groove 2. A fixed block 52 is fixedly connected to the side of the fixed frame 4 close to the ratchet 51. A pawl 53 is rotatably connected to the side of the fixed frame 4 close to the fixed block 52. The front end of the pawl 53 is movably inserted in the tooth groove of the ratchet 51. A spring 54 is fixedly connected between the pawl 53 and the fixed block 52.

[0021] By adopting the above technical solution, when it is necessary to extend the traction rope 3, the pawl 53 on one side is moved and the spring 1 54 is compressed to make the pawl 53 disengage from the inside of the ratchet 51, and the restriction on the rotation of the ratchet 51 in the extension direction is released, thereby facilitating the traction rope 3 to be pulled out from the inside of the winding groove 2 and the winding spring 11 is wound. After it is extended to the appropriate position, the pawl 53 is released and the elastic force of the spring 1 54 is used to re-engage the pawl 53 in the clamping groove of the ratchet 51, thereby restricting the rotation of the corresponding ratchet 51 in the extension direction. When it is necessary to shorten the extended length of the traction rope 3, the pawl 53 on the other side is moved to release the restriction on the rotation in the winding direction of the corresponding ratchet 51, and then the elastic force of the winding spring 11 is used to realize the automatic winding operation of the traction rope 3.

[0022] The clamping mechanism 9 includes an insertion rod 91, which is fixedly connected to the side of the connecting frame 7 away from the body 1. A clamping slot 92 is provided on the outer side of the front end of the insertion rod 91. A connecting seat 93 is fixedly connected to one side of the collar 8. A slot 94 is provided on the side of the connecting seat 93 away from the collar 8. The front end of the insertion rod 91 is movably inserted into the slot 94. Slide grooves 95 are provided inside the connecting seat 93 and on both sides of the slot 94. A clamping block 97 is slidably clamped inside the slide groove 95, and the side of the clamping blocks 97 close to each other is movably clamped in the slot 92.

[0023] By adopting the above technical solution, when the traction rope 3 is connected to the collar 8, the front end of the insertion rod 91 is movably inserted into the interior of the slot 94, and the clamping block 97 is inserted into the interior of the clamping slot 92, thereby limiting the withdrawal of the insertion rod 91. When an emergency occurs, the traction rope 3 is pulled hard to make the clamping block 97 disengage from the interior of the clamping slot 92, thereby releasing the restriction on the withdrawal of the insertion rod 91 and facilitating the separation of the collar 8 and the traction rope 3.

[0024] The sides of the clamping blocks 97 that are away from each other are fixedly connected to the guide rods 96 , and the ends of the guide rods 96 that are away from each other are movably extended to the outside of the connecting seat 93 .

[0025] By adopting the above technical solution and providing the guide rod 96 , the movement of the clamping block 97 can be guided.

[0026] A spring 98 is provided between the side of the clamping block 97 that is away from each other and the inner wall of the sliding groove 95 . The spring 98 is movably sleeved on the outer side of the guide rod 96 .

[0027] By adopting the above technical solution and providing the spring 98 , the clamping block 97 can be easily reset. At the same time, the elastic force of the spring 98 can make the clamping block 97 and the clamping slot 92 more firmly connected.

[0028] The top of the fixed frame 4 is provided with an unlocking slot 55 , and the top of the pawl 53 movably extends to the outside of the unlocking slot 55 , and the pawl 53 is slidably engaged in the unlocking slot 55 .

[0029] By adopting the above technical solution and providing the unlocking groove 55 , the pawl 53 can slide along the inside of the unlocking groove 55 , thereby completing the unlocking operation.

[0030] The inner wall of the slot 92 away from the body 1 and the front end of the insertion rod 91 are both configured as inclined surfaces.

[0031] By adopting the above technical solution, by setting the inner wall of the slot 92 away from the side of the body 1 and the front end of the insertion rod 91 to be inclined, it is easier to install and disassemble the insertion rod 91 and the connecting seat 93.

[0032] A fixing ring 12 is fixedly connected to a side of the body 1 away from the locking mechanism 5 .

[0033] By adopting the above technical solution and providing the fixing ring 12, the device can be better held in the hand.

[0034] Working principle: When using the traction rope, when it is necessary to extend the traction rope 3, by toggling the pawl 53 on one side and compressing the spring 1 54, the pawl 53 is disengaged from the inside of the ratchet 51, and the restriction on the rotation of the ratchet 51 in the extension direction is released, thereby facilitating the traction rope 3 to be pulled out from the inside of the winding groove 2 and the winding spring 11 is wound. After stretching to a suitable position, the pawl 53 is released and the elastic force of the spring 1 54 is used to re-engage the pawl 53 in the clamping groove of the ratchet 51, thereby restricting the rotation of the corresponding ratchet 51 in the extension direction. When it is necessary to shorten the extended length of the traction rope 3, by toggling the pawl 53 on the other side, the restriction on the rotation in the winding direction of the corresponding ratchet 51 is released, and then the elastic force of the winding spring 11 is used to realize the automatic winding of the traction rope 3.

[0035] When connecting the traction rope 3 to the collar 8, the front end of the insertion rod 91 is movably inserted into the interior of the slot 94, and the clamping block 97 is inserted into the interior of the clamping groove 92. By the elastic force of the slot 94, the clamping groove 92 and the clamping block 97 are clamped more tightly, thereby restricting the pulling out of the insertion rod 91. When an emergency occurs, by pulling the traction rope 3 forcefully, with the cooperation between the clamping block 97 and the inclined surface on one side of the clamping groove 92, the two clamping blocks 97 are simultaneously pushed to move away from each other, so that the clamping block 97 is disengaged from the interior of the clamping groove 92, thereby releasing the restriction on the pulling out of the insertion rod 91 and facilitating the separation of the collar 8 and the traction rope 3.

[0036] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
