Description

Technical Field

[0001] The utility model relates to the technical field of pet traction devices, in particular to a self-locking structure of a pet traction device switch. Background Art

[0002] With the improvement of living standards, keeping pets has become accepted by most people. Taking pets out for a stroll during leisure time has become a pleasant activity for people. People often use pet leashes to restrain their pets to prevent them from running around, or to allow them to play around with them.

[0003] In the prior art, for example, Chinese patent CN203597221U discloses a self-locking structure for a pet traction device switch, which includes a radial locking block, a switch button, and a return spring. A guide slide hole communicating with a mounting cavity is provided on the housing of the main body at the handle. One end of the radial locking block is engaged with a ratchet buckle on the outside of the turntable, and the other end is connected to the lower end of the switch button via a return spring. The upper end of the switch button is located on the outside of the main body, and a locking buckle is provided on the switch button. The switch button is locked to the guide slide hole via the locking buckle. This utility model has a compact structure and is flexible to use. The newly designed locking buckle simplifies the switch structure, and during use, only the thumb needs to be pushed forward to complete the locking operation, thereby controlling the turntable's rotatable state and limited stop state, making operation more convenient. The braking process of the switch button is simplified, making braking easier and more convenient for consumers.

[0004] In the above patent, locking can be completed by pushing the thumb forward, which can control the rotatable state and the restricted stop state of the turntable, and has a good control effect. However, when controlling the stop state of the turntable, the person's thumb needs to continuously push the switch button to make the spring continue to deform and contract, so that the locking block always contacts the surface of the turntable to stop. When used for a long time, the person's thumb is burdened, which can easily cause soreness in the person's fingers. Therefore, it is necessary to propose a new type of pet leash switch self-locking structure. Utility Model Content

[0005] The utility model mainly provides a pet traction device switch self-locking structure which is convenient for stopping the turntable of the winding traction rope for a long time, avoiding the need for a person's fingers to push the switch for a long time to control the turntable.

[0009] Preferably, the inner surface of the handle is fixedly connected to a slide rod, and the outer surface of the slide rod is slidably connected to the inner surface of the moving block, so that when the moving block moves, it will slide along the surface of the slide rod, thereby playing a guiding role.

[0010] Preferably, the outer surface of the sliding rod is sleeved with a spring, and the spring is matched with the moving block. The outer surface of the mounting rod slides through the handle and the outer surface of the tractor body in sequence, so that under the action of the spring, the spring pushes the moving block to move, so that the mounting rod drives the friction block away from the turntable.

[0011] Preferably, clamping plates are symmetrically provided on the inner surface of the mounting frame, and the relative outer surfaces of the two clamping plates are in contact with the outer surface of the tractor body, so as to facilitate clamping and fixing the two sides of the tractor body when the two clamping plates move toward each other.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] 1. In the present invention, the push block is pushed so that the movable block slides along the surface of the slide rod, and the mounting rod drives the friction block to contact the surface of the turntable, which plays a role of braking and locking. At the same time, the position of the movable block will change accordingly, so that the position of the fixing hole and the position of the touch rod coincide with each other, which is convenient for a person to push the touch rod to insert it into the fixing hole, thereby limiting the position of the movable block and preventing the spring rebound force from pushing the movable block to reset, so that the friction block will contact the surface of the turntable for a long time and be locked, thereby solving the problem in the background technology that when the turntable is stopped for a long time, the thumb of the person needs to continuously push the switch button, which causes a heavy burden on the thumb of the person and easily causes soreness in the fingers of the person.

[0016] 2. In the utility model, through the coordinated use of the cleaning component, when the pet leash is wound, the leash will pass between the two scrapers. The scrapers will remove the debris on the surface of the leash, thereby playing a cleaning role and preventing the debris from following the leash into the traction device body and causing internal blockage.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] See also Figure 1-5 The utility model provides a technical solution: a self-locking structure of a pet traction device switch, including a traction device body 1, a turntable 5 is arranged inside the traction device body 1, a baffle 2 is fixedly connected to the front surface of the traction device body 1, a handle 3 is fixedly connected to the outer surface of the traction device body 1, a push block 7 is arranged on the top of the handle 3, a moving block 8 is fixedly connected to the bottom of the push block 7, the outer surface of the moving block 8 is fixedly connected to a mounting rod 11, the outer surface of the mounting rod 11 is fixedly connected to a friction block 12, the inner top of the handle 3 is fixedly connected to a fixed block 14, and the inner surface of the fixed block 14 is slidably connected to a touch rod 15; a cleaning component 4, the cleaning component 4 is arranged on the outer surface of the traction device body 1, and the cleaning component 4 includes a mounting frame 401.

[0026] like Figure 2-3 As shown, a fixing hole 13 is provided on the rear surface of the moving block 8, and the fixing hole 13 matches the position of the touch rod 15, so that when the moving block 8 moves, the position of the fixing hole 13 coincides with the touch rod 15, and the touch rod 15 is inserted into the fixing hole 13 for limiting.

[0027] like Figure 4 As shown, a plurality of grooves 6 are equidistantly provided on the outer surface of the turntable 5. The turntable 5 and the friction block 12 are matched with each other. By providing a plurality of grooves 6 on the outer surface of the turntable 5, the friction force between the turntable 5 and the friction block 12 is increased, thereby facilitating effective braking of the turntable 5.

[0028] like Figure 4 As shown, the inner surface of the handle 3 is fixedly connected to a slide rod 9, and the outer surface of the slide rod 9 is slidably connected to the inner surface of the moving block 8, so that when the moving block 8 moves, it will slide along the surface of the slide rod 9, playing a guiding role.

[0029] like Figure 4 As shown, the outer surface of the slide rod 9 is provided with a spring 10, and the spring 10 is matched with the moving block 8. The outer surface of the mounting rod 11 slides through the handle 3 and the outer surface of the tractor body 1 in sequence, so that under the action of the spring 10, the spring 10 pushes the moving block 8 to move, so that the mounting rod 11 drives the friction block 12 away from the turntable 5.

[0030] like Figure 5 As shown, the inner surface of the mounting frame 401 is symmetrically provided with clamping plates 404, and the relative outer surfaces of the two clamping plates 404 are in contact with the outer surface of the tractor body 1, so that the two sides of the tractor body 1 can be clamped and fixed when the two clamping plates 404 move toward each other.

[0031] like Figure 5 As shown, the inner surfaces of the two clamping plates 404 are rotatably connected to the threaded rods 403, and the outer surfaces of the two threaded rods 403 are threadedly penetrated by the mounting frame 401, so that when the threaded rods 403 are threadedly rotated in the inner wall of the mounting frame 401, the clamping plates 404 are driven to move toward the outer surface of the tractor body 1.

[0032] like Figure 1-2 and Figure 4 As shown, the outer surface of the mounting frame 401 is fixedly connected to a fixing frame 402, and the inner surface of the fixing frame 402 is symmetrically fixedly connected to a scraper 405, so that when the pet leash is rolled up, the leash will move between the two scrapers 405, and the scrapers 405 will scrape off foreign matter on its surface, thereby playing a cleaning role.

[0033] The method of use and working principle of this device: When the self-locking structure of the pet traction device switch is used, the push block 7 is pushed to drive the moving block 8 to slide along the outer surface of the slide rod 9. The moving block 8 will squeeze the spring 10, causing it to deform and shrink, so that the mounting rod 11 will slide between the wrench 3 and the inner wall of the traction device body 1, driving the friction block 12 to contact the outer surface of the turntable 5. The multiple grooves 6 equidistantly provided on the outer surface of the turntable 5 increase the friction force. The idle turntable 5 rotates inside the traction device body 1 to prevent the traction rope wrapped around the outer surface of the turntable 5 from being continuously released outward when the pet runs around. When the friction block 12 contacts the surface of the turntable 5 and the brake is stopped, the position of the moving block 8 will change accordingly, so that the position of the fixing hole 13 coincides with the position of the touch rod 15. At this time, the person only needs to push the touch rod 1 5 slides in the fixed block 14, so that the touch rod 15 is inserted into the fixed hole 13 corresponding to the position to lock the movable block 8, preventing the rebound force of the spring 10 from pushing the movable block 8 to reset, so that the friction block 12 will be locked against the surface of the turntable 5 for a long time. By arranging a mounting frame 401 at the rope inlet and outlet position of the traction device body 1, the two threaded rods 403 rotating in the mounting frame 401 drive the two clamping plates 404 to contact the two sides of the mounting frame 401, so that the fixing frame 402 is fixed at the telescopic inlet and outlet position, so that when the pet traction rope is wound, the traction rope will pass between the two scrapers 405, and the scrapers 405 will remove the debris on the surface of the traction rope, thereby playing a cleaning role and preventing the debris from following the traction rope into the traction device body 1 and causing internal blockage, and the traction rope is highly practical.
