Description

Technical Field

[0001] The utility model relates to the technical field of pet traction devices, in particular to a small dog leash switch structure. Background Art

[0002] A dog leash, also commonly known as a dog leash or lead, is a tool used to pull and control a dog's movements. Suitable for small and medium-sized dogs, they come in a variety of styles and are very comfortable for dogs to wear.

[0003] Currently, existing dog leashes are relatively large, most with handles, and are not compact enough. However, with the increasing number of people keeping small pets such as small dogs and cats in the domestic market, traditional dog leashes are too bulky. To reduce the size of a dog leash, or even eliminate the handle, the traditional dog leash switch structure would need to be scaled down. However, this approach is insufficient for smaller dog leashes or similar handle-less dog leashes. Therefore, it is necessary to propose a small dog leash switch structure to address this issue. Utility Model Content

[0004] To address these shortcomings, the present invention provides a compact dog leash switch structure, designed to improve the bulkiness of conventional dog leashes. If a dog leash needs to be smaller, or even have its handle removed, the conventional dog leash switch structure would need to be scaled down proportionally. This approach is difficult to meet the needs of smaller dog leashes or similar dog leashes without handles.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a small dog leash switch structure, which comprises a dog leash component and a switch structure.

[0007] The dog leash assembly includes a dog leash housing and a leash, the dog leash housing is provided with a first through hole, the first through hole is provided with a notch, the dog leash housing is rotatably connected to a winding rod, two ends of the winding rod are fixed with a disc, the surface of the disc is fixed with a positioning tooth, the leash is wound in the disc, and the end of the leash extends to the outside of the dog leash housing; the switch structure includes a push button, a locking block, a button and a spring, a slide groove is formed around the push button, the push button is slidably arranged in the first through hole through the slide groove, a second through hole is formed inside the push button, one end of the locking block is fixed with a locking tooth, the locking tooth is engaged with one side of the positioning tooth, the locking block is mounted on the bottom of the push button by a screw, the button is slidably arranged in the first through hole, and blocks are fixed on both sides of the button, the blocks are movably engaged in the notch, and the spring is installed between the button and the locking block.

[0008] In one embodiment of the present invention, a guide groove is provided inside the second through hole, and guide ribs matching the guide groove are fixed on both sides of the button, and the guide ribs slide in the guide groove.

[0009] In one embodiment of the present invention, a first positioning groove is formed on the surface of the locking block, and a positioning rib matching the first positioning groove is fixed to the bottom of the push button, and the positioning rib is engaged with the inside of the first positioning groove.

[0010] In one embodiment of the present invention, a groove matching the button, the stopper and the guide rib is formed on the upper surface of the locking block, and the button, the stopper and the guide rib are movably connected in the groove.

Positioning teeth 132 are fixed on the surface of the disc 131. The leash 120 is wound in the disc 131, and the end of the leash 120 extends to the outside of the dog leash housing 110.

[0026] See also Figure 1-Figure 3 and Figure 5-Figure 7 The switch structure 200 includes a push button 210, a locking block 220, a button 260 and a spring 270. A sliding groove 211 is formed around the push button 210. The push button 210 is slidably set at the first through hole 111 through the sliding groove 211. A second through hole 212 is formed inside the push button 210. One end of the locking block 220 is fixed with a locking tooth 224, and the locking tooth 224 is engaged with one side of the positioning tooth 132. The locking block 220 is installed at the bottom of the push button 210 by a screw 230. The button 260 is slidably set inside the first through hole 111. Stoppers 261 are fixed on both sides of the button 260. The stoppers 261 are movably engaged in the notch 112. The spring 270 is installed between the button 260 and the locking block 220.

[0027] A guide groove 213 is defined within the second through hole 212. Guide ribs 262 are fixed to both sides of the button 260, matching the guide grooves 213. The guide ribs 262 slide within the guide grooves 213. The guide grooves 213 and guide ribs 262 provide greater stability for the push button 210 and the locking block 220 during movement. A first positioning groove 221 is formed on the surface of the locking block 220. A positioning rib 250 is fixed to the bottom of the push button 210, matching the first positioning groove 221. The positioning rib 250 engages with the interior of the first positioning groove 221. The positioning ribs 250 and the first positioning groove 221 provide greater stability for the push button 210 and the locking block 220 during movement, while also facilitating positioning and assembly.

[0028] The locking block 220 has a groove 222 formed on its upper surface that matches the button 260, the stopper 261, and the guide rib 262. The button 260, the stopper 261, and the guide rib 262 are movably connected in the groove 222. The groove 222 facilitates the upward and downward movement of the button 260, the stopper 261, and the guide rib 262. The locking block 220 has a nail hole 223 formed on its surface that matches the screw 230. The push button 210 has a protrusion 240 formed on its surface. The protrusion 240 has a threaded hole 241 formed inside it that matches the screw 230. The screw 230 passes through the nail hole 223 and is threadedly connected to the interior of the threaded hole 241. The screw 230 is used to conveniently install and secure the button 260 and the stopper 261.

[0029] A positioning column 263 matching the spring 270 is fixed on the button 260, one end of the spring 270 is sleeved on the positioning column 263, and a second positioning groove 2221 matching the spring 270 is formed inside the groove 222, and the other end of the spring 270 is placed inside the second positioning groove 2221. The positioning column 263 and the second positioning groove 2221 can facilitate the positioning of the spring 270, making the spring 270 more stable during elastic expansion and contraction.

[0030] Specifically, the working principle of the switch structure of the small dog leash is as follows: when the button 260 is pressed, the block 261 and the guide rib 262 will move downward into the groove 222 under the elastic action of the spring 270, so that the block 261 will be below the first through hole 111. At the same time, the push button 210 is manually pushed forward, and the push button 210 and the lock block 220 move together. The locking tooth 224 on the lock block 220 will move away from the positioning tooth 132 on the disc 131. At this time, the switch is in the unlocked state, and the leash 120 can be freely extended. When the push button 210 is slid backward, the latching teeth 224 on the locking block 220 move to the side of the positioning teeth 132, and the stopper 261 aligns with the notch 112. Under the elastic action of the spring 270, the button 260 and the stopper 261 are simultaneously pushed upward, and the stopper 261 is stuck in the notch 112 and cannot move. At this time, the leash 120 is locked and cannot be pulled out. This can meet the requirements of opening and closing small retractable dog leashes and can be used on handleless, oval-shaped, and other special-shaped dog leashes. It is easy to carry and compact. When in use, the dog leash can be locked and unlocked by simply pressing, pushing forward, or pulling backward, making it easier and more convenient to use.
