[0026] Example

[0027] Reference Figures 1-4 A retractable pet leash, including

[0028] Outer shell 1;

[0029] The cover plate 2, handle 3, positioning wheel 4, limit wheel 5, fixed box 6, control plate 7 and positioning rod 16 are connected together. The cover plate 2 is movably connected to the front side of the outer shell 1. The handle 3 is fixedly connected to the right side of the outer shell 1. The positioning wheel 4 is rotatably connected to the inner wall of the outer shell 1. The limit wheel 5 is fixedly connected to the front side of the positioning wheel 4 and passes through the cover plate 2. The fixed box 6 is fixedly connected to the top of the outer shell 1. The control plate 7 is slidably connected to the top of the handle 3. The positioning rod 16 is slidably connected to the inside of the fixed box 6 and the bottom of the positioning rod 16 extends into the inside of the outer shell 1. The outer wall of the positioning wheel 4 is provided with multiple positioning grooves at equal intervals and the positioning grooves are adapted to the positioning rod 16.

[0030] The positioning mechanism is connected to the positioning rod 16 and is used to fix the positioning wheel 4.

[0031] Through the above-mentioned mechanism: the handle 3 makes it easy to pick up; the positioning wheel 4 makes it easy to fix the limiting wheel 5; the limiting wheel 5 makes it easy to wind the traction rope; the control plate 7 makes it easy to drive the positioning mechanism; the positioning mechanism makes it easy to drive the positioning rod 16 to move; and the positioning rod 16 cooperates with the positioning groove to fix the positioning wheel 4, thereby fixing the limiting wheel 5 and thus fixing the traction rope.

[0032] As a preferred embodiment of this utility model, the positioning mechanism includes: a control plate 7, a push rod 9, a reset plate 10, an unlocking rod 11, and an unlocking plate 14;

[0033] The control plate 7 is slidably connected to the top of the handle 3. The push rod 9 is fixedly connected to the left side of the control plate 7, and the left side of the push rod 9 extends into the interior of the fixed box 6. The reset plate 10 is slidably connected to the interior of the fixed box 6. The right side of the reset plate 10 is fixedly connected to the left side of the push rod 9. The unlocking rod 11 is rotatably connected to the front side of the reset plate 10. The unlocking plate 14 is slidably connected to the interior of the fixed box 6, and the bottom of the unlocking plate 14 is fixedly connected to the top of the positioning rod 16. The front side of the unlocking plate 14 is rotatably connected to the rear side of the unlocking rod 11. By pushing the control plate 7 to the left, the push rod 9 will move to the left. The movement of the push rod 9 will push the reset plate 10 to the left. At this time, the movement of the reset plate 10 will push the unlocking rod 11 to move upward and drive the unlocking plate 14 to move upward. The upward movement of the unlocking plate 14 will drive the positioning rod 16 to move upward and disengage from the positioning groove, thus unlocking the positioning wheel 4 and unlocking the traction rope.

[0034] As a preferred embodiment of this utility model, a support plate 12 is fixedly connected to the inner wall of the fixed box 6. The left side of the support plate 12 is slidably connected to the right side of the unlocking plate 14. The support plate 12 facilitates the limiting of the unlocking plate 14, so that the unlocking plate 14 can move stably and vertically.

[0035] As a preferred embodiment of this utility model, a reset spring 13 is fixedly connected to the right side of the support plate 12. The right side of the reset spring 13 is fixedly connected to the left side of the reset plate 10. Through the elastic force of the reset spring 13, the reset plate 10 can be easily pushed to the right to reset and drive the control plate 7 to reset.

[0036] As a preferred embodiment of this utility model, a positioning spring 15 is fixedly connected to the top inner wall of the fixed box 6. The bottom of the positioning spring 15 is fixedly connected to the top of the unlocking plate 14. Through the elastic force of the positioning spring 15, the unlocking plate 14 can be easily pushed down to reset, thereby driving the positioning rod 16 to engage with the positioning groove.

[0037] As a preferred embodiment of this utility model, a limiting sleeve 8 is fixedly connected to the top of the handle 3. The inner wall of the limiting sleeve 8 is slidably connected to the outer wall of the control plate 7. The limiting sleeve 8 facilitates the limiting of the control plate 7, so that the control plate 7 can move horizontally in a stable manner.

[0038] The working principle of this utility model is as follows: In actual use, the leash is sleeved on the outer wall of the limiting wheel 5, and one end of the leash extends to the outside of the outer shell 1. When in use, the leash is sleeved on the pet. When the leash needs to be released, the control plate 7 is manually pushed to the left. When the control plate 7 moves, it drives the push rod 9 to move to the left. The limiting sleeve 8 can limit the control plate 7, allowing it to move stably laterally. The push rod 9 moves the reset plate 10 to the left, which compresses the reset spring 13. Simultaneously, the reset plate 10 moves the unlocking rod 11 upward, which in turn pushes the unlocking plate 14 upward. This upward movement of the unlocking plate 14 compresses the positioning spring 15, and simultaneously, the unlocking plate 14 moves the positioning rod 16 upward, disengaging it from the positioning groove, thus unlocking the positioning wheel 4. Pulling the traction rope extends it out of the outer casing 1. By releasing the control plate 7, the reset spring 13 pushes the reset plate 10 to the right to reset. When the reset plate 10 moves, it drives the push rod 9, which in turn drives the control plate 7 to the right to reset. At the same time, the movement of the reset plate 10 pulls the unlocking rod 11. At this time, the positioning spring 15 loses its restraint and pushes the unlocking plate 14 down. The movement of the unlocking plate 14 drives the positioning rod 16 down to engage with the positioning groove and fix the positioning wheel 4, thereby fixing the limit wheel 5. At this time, the traction rope is fixed. When it is necessary to rewind the traction rope, push the control plate 7 to move the positioning rod 16 to unlock the positioning wheel 4. Then, directly rotate the limit wheel 5 on the front side of the cover plate 2 to drive the limit wheel 5 and the positioning wheel 4 to rotate and rewind the traction rope. After rewinding, releasing the control plate 7 will automatically fix the positioning wheel 4, which is convenient to use.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
