Description

Technical Field

[0001] This utility model relates to the field of rope buckle device technology, and in particular to a rope buckle device for pet leashes. Background Technology

[0002] The ends of existing pet leashes are usually tied into a loop by hand for easy gripping, or simply wrapped around the hand, without any other leash structure. This makes them inconvenient to use, and when the leash is too long, it needs to be wrapped around the hand multiple times, so the effect is not ideal.

[0003] Currently, one type of pet leash buckle device in the technology requires the user to constantly adjust the position of the leash when fixing it using the buckle structure, due to the leash being suspended in the air, which makes it impractical. In addition, the existing pet leash buckle devices all use multiple bolts for installation and removal, which is time-consuming and laborious, further reducing their practicality. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor practicality in the existing technology of using rope buckle structures to fix leashes, which require users to constantly adjust the position of the leash due to the suspension of the leash, and the fact that the leash is installed and removed using multiple bolts, which is time-consuming and labor-intensive. Therefore, this invention proposes a rope buckle device for pet leashes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a leash buckle device for pet leashes, comprising a lower housing, a connecting hole at one end of the lower housing, two fixing posts fixed on the inner bottom wall of the lower housing, a pressing plate inside the lower housing, an upper housing at the top of the lower housing, a locking plate fixed on both sides of the bottom end of the upper housing, a movable plate on both sides of the lower part of the upper housing, a locking post fixed at the opposite end of each of the two movable plates, locking holes matching the locking posts at both ends of the inner wall of the lower housing, and a driving structure inside the upper housing for driving the two movable plates to move in opposite directions.

[0006] Preferably, the driving structure includes a bidirectional screw disposed in the upper housing, with displacement plates threadedly connected to both sides of the outer wall of the bidirectional screw, and limit posts slidably connected to both ends of the two displacement plates, with connecting blocks fixed to the bottom ends of the two displacement plates, and the bottom ends of the two connecting blocks penetrating the upper housing and respectively fixed to the two movable plates.

[0007] Preferably, the inner walls at both ends of the lower housing are provided with openings, springs are fixed on the inner bottom walls of the two openings, connecting plates are fixed on the top ends of the two springs, and the opposite ends of the two connecting plates are respectively fixed to the two ends of the pressing plate.

[0008] Preferably, one end of the bidirectional screw is fixed with a connecting post, the end of the connecting post away from the bidirectional screw passes through the upper housing and is fixed with a rotating plate, one end of the bidirectional screw is rotatably connected to the upper housing, both ends of the limiting post are fixed to the upper housing, and the bottom end of the upper housing is provided with a moving groove that matches the connecting block.

[0009] Preferably, one end of the upper housing has a slot, the rotating plate is disposed in the slot, a support plate is fixed on the inner wall of the slot, a pin is provided in the support plate, and the output end of the pin is disposed in the rotating plate.

[0010] Preferably, baffles are fixed to the top of both fixed columns, guide columns are fixed to the four corners of the bottom of the upper housing, guide grooves matching the guide columns are opened at the four corners of the top of the lower housing, and a soft pad is fixed to the top of the pressing plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, when fixing the traction rope, simply place one end of the traction rope under the pressing plate. By pressing the pressing plate, the end of the traction rope can be limited, allowing the user to proceed with subsequent fixing operations without worrying about the traction rope swaying and affecting the fixing efficiency. By rotating the rotating plate, the connecting column can be rotated, which in turn drives the bidirectional screw to rotate, causing the two displacement plates to move towards or away from each other under the limitation of the limiting column. This, in turn, causes the two moving plates connected by the two connecting blocks to move towards or away from each other. When the two moving plates move towards each other, they will cause the two locking pins to disengage from the locking holes, allowing the upper shell to be removed directly for quick disassembly. When the two moving plates move in opposite directions, they will cause the two locking pins to enter the locking holes, limiting the lower and upper shells for quick installation.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, as Figure 1-4 As shown, this utility model provides a leash buckle device for pet leashes, including a lower housing 1, a connecting hole 2 at one end of the lower housing 1, two fixing posts 3 fixed on the inner bottom wall of the lower housing 1, a pressing plate 5 inside the lower housing 1, an upper housing 10 at the top of the lower housing 1, a locking plate 11 fixed on both sides of the bottom end of the upper housing 10, a movable plate 14 on both sides of the lower part of the upper housing 10, a locking post 15 fixed at the opposite end of the two movable plates 14, locking holes 22 matching the locking posts 15 at both ends of the inner wall of the lower housing 1, and a driving structure 16 inside the upper housing 10 for driving the two movable plates 14 to move in opposite directions.

[0021] The effect achieved by the entire embodiment 1 is that when one end of the traction rope is placed under the pressing plate 5, the user can press the pressing plate 5 to limit one end of the traction rope. At this time, the user can wrap the traction rope around the two fixing posts 3 and move it out of the connecting hole 2. Then, the user puts the upper shell 10 on. Through the operation of the drive structure 16, the two moving plates 14 are driven to move in opposite directions, which will drive the two locking posts 15 into the locking holes 22, thereby limiting the lower shell 1 and the upper shell 10 and fixing the upper shell 10 and the lower shell 1. After the upper shell 10 is installed, the two locking plates 11 will squeeze the traction rope in the lower shell 1 to achieve the effect of clamping and fixing. Moreover, due to the design of the fixing posts 3 wrapping, even if one end is squeezed unstable, the traction rope will not fall off, and the stability is stronger.

[0022] Example 2, as Figure 1-4 As shown, the drive structure 16 includes a bidirectional screw 1601 disposed within the upper housing 10. Displacement plates 1602 are threadedly connected to both sides of the outer wall of the bidirectional screw 1601. Limiting posts 1603 are slidably connected to both ends of the two displacement plates 1602. Connecting blocks 1604 are fixed to the bottom ends of both displacement plates 1602. The bottom ends of the two connecting blocks 1604 penetrate the upper housing 10 and are respectively fixed to two movable plates 14. Openings 7 are provided on the inner walls of both ends of the lower housing 1. Springs 8 are fixed to the inner bottom walls of both openings 7. Connecting plates 9 are fixed to the top ends of both springs 8. The opposite ends of the two connecting plates 9 are respectively fixed to the two ends of the pressing plate 5. A connecting post 17 is fixed to one end of the bidirectional screw 1601, and the connecting post 17 is located away from the bidirectional screw. One end of 1601 passes through the upper housing 10 and is fixed with a rotating plate 18. One end of the bidirectional screw 1601 is rotatably connected to the upper housing 10. Both ends of the limiting post 1603 are fixed to the upper housing 10. The bottom end of the upper housing 10 is provided with a moving groove 23 that matches the connecting block 1604. One end of the upper housing 10 is provided with a slot 21. The rotating plate 18 is located in the slot 21. A support plate 19 is fixed on the inner wall of the slot 21. A pin 20 is provided in the support plate 19. The output end of the pin 20 is located in the rotating plate 18. The top ends of the two fixed posts 3 are fixed with baffles 4. The four corners of the bottom end of the upper housing 10 are fixed with guide posts 12. The four corners of the top end of the lower housing 1 are provided with guide grooves 13 that match the guide posts 12. The top end of the pressing plate 5 is fixed with a soft pad 6.

[0023] The effect achieved by the entire embodiment 2 is that by rotating the rotating plate 18, the connecting column 17 can be rotated, thereby driving the bidirectional screw 1601 to rotate. This causes the two displacement plates 1602 to move towards or away from each other under the limitation of the limiting column 1603, thereby driving the two moving plates 14 connected by the two connecting blocks 1604 to move towards or away from each other. When the two moving plates 14 move towards each other, they will cause the two locking pins 15 to disengage from the locking hole 22. At this time, the upper housing 10 can be directly removed, achieving the effect of quick disassembly. When the two moving plates 14 move in opposite directions, they will cause the two locking pins 15 to enter into the locking hole 22, achieving the limitation of the lower housing 1 and the upper housing 10, achieving the effect of quick installation. The setting of the spring 8 ensures that there is always a gap between the pressing plate 5 and the inner bottom wall of the lower housing 1, making it easy for the user to insert one end of the traction rope. The setting of the support plate 19 and the pin 20 can limit the position of the rotating plate 18 and prevent it from rotating on its own.

[0024] Working principle: When using this device, one end of the traction rope is placed under the pressing plate 5. By pressing the pressing plate 5, the end of the traction rope can be limited. At this time, the user can wrap the traction rope around the two fixing posts 3 and move it out of the connecting hole 2. Then, the user places the upper housing 10 on top. By rotating the rotating plate 18, the user can drive the connecting post 17 to rotate, thereby driving the bidirectional screw 1601 to rotate. This causes the two displacement plates 1602 to move in opposite directions at the limit post 1603, driving the two moving plates 14 to move in opposite directions. This will drive the two locking posts 15 into the locking hole 22, achieving the limitation of the lower housing 1 and the upper housing 10, and fixing the upper housing 10 and the lower housing 1 together. After the upper housing 10 is installed, the two locking plates 11 will squeeze the traction rope in the lower housing 1 to achieve the effect of clamping and fixing. Moreover, due to the design of the fixing post 3 wrapping, even if one end is not stable, the traction rope will not fall off, resulting in stronger stability.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
