Description

Technical Field

[0001] This utility model belongs to the field of pet supplies technology, and in particular relates to a pet collar tension adjuster. Background Technology

[0002] With the increasing popularity of pet ownership, pets are participating more and more in outdoor activities in their daily lives, such as walks, training, and travel. To ensure pet safety and facilitate effective management by owners, leashes or adjustable loops are commonly used for restraint and management when pets are out. To accommodate different body sizes and activity levels, leashes or adjustable loops need to have adjustable tension.

[0003] Currently, there are two main types of adjustment structures: one type uses knots, buckles, D-rings, or Velcro to fix the length of the rope. Although the structure is simple, it is prone to loosening after repeated use or stress, resulting in poor stability. The other type has a sliding lock on the rope, which can be manually slid to change the effective length. This is relatively convenient to operate, but the locking principle mainly relies on the friction between the contact surfaces. When the pet suddenly breaks free or moves violently, the sliding may fail. Furthermore, after long-term use, the contact surfaces wear down, causing the clamping force to decrease and making it difficult to maintain the set tightness.

[0004] Therefore, a pet collar tension adjuster is particularly needed to solve the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of existing adjustment structures, such as easy loosening after repeated use, easy slippage of friction lock, and decreased clamping force after wear, making it difficult to stably maintain the set tightness, this utility model provides a pet collar tightness adjuster.

[0006] This utility model is achieved through the following technical means: a pet collar tension adjuster, including a pull cord, a fixed plate, a cover, a pressure plate, screws, a docking frame, a support plate, a limiting frame, a pressure block, an adjusting rod, and a nut. The cover is fixedly connected to the lower part of the fixed plate. The pull cord passes through the fixed plate, with one end of the pull cord remaining inside the fixed plate and the other end extending to the outside of the fixed plate to form a loop. The pressure plate is attached to the lower surface of one end of the pull cord. The pressure plate is installed and fixed inside the fixed plate by two symmetrically arranged screws. The docking frame is fixedly connected to the cover. The support plate is fixedly connected to the inside of the fixed plate. The limiting frame is fixedly connected to the support plate. The lower part of the limiting frame is inserted into the docking frame. The pull cord passes through the inside of the limiting frame. The pressure block is slidably arranged inside the limiting frame. An adjusting rod is rotatably arranged on the top of the pressure block. The adjusting rod passes through the limiting frame and rotatably engages with the limiting frame. A nut is rotatably arranged on the upper part of the fixed plate. The nut is threadedly engaged with the adjusting rod.

[0007] As a preferred option, the pull rope is made of high-strength, wear-resistant nylon braided rope.

[0008] Preferably, the lid is fixed to the mounting plate by ultrasonic welding.

[0009] Preferably, a rubber gasket is provided on the top surface of the tablet.

[0010] Preferably, the bottom surface of the pressing block is also provided with a rubber gasket.

[0011] Preferably, the top of the adjusting rod is in contact with the top of the nut, and the pressure block is located at a high position inside the limiting frame.

[0012] Beneficial effects: This utility model, by setting a limiting frame, a pressure block, an adjusting rod, and a nut, can reliably adjust and stably lock the tightness of the loop formed by the pull rope. Users only need to rotate the nut clockwise or counterclockwise to drive the adjusting rod to move the pressure block down or up along the limiting frame, thereby tightening or releasing the pull rope. The operation is simple and improves the convenience of use. Attached Figure Description

[0021] Example: Pet collar tightness adjuster, such as Figures 1-7As shown, the assembly includes a pull rope 1, a fixing plate 2, a cover 3, a pressure plate 4, screws 5, a connecting frame 6, a support plate 7, a limiting frame 8, a pressure block 9, an adjusting rod 10, and a nut 11. The pull rope 1 is made of high-strength, wear-resistant nylon braided rope, possessing excellent flexibility and tensile strength. The cover 3 is ultrasonically welded to the lower part of the fixing plate 2, ensuring a stable connection between the cover 3 and the fixing plate 2. The pull rope 1 passes through the fixing plate 2, with one end remaining inside the fixing plate 2 and the other end extending to the outside of the fixing plate 2, forming a loop. A pressure plate 4 is attached to the lower surface of one end of the pull rope 1. The pressure plate 4 is installed and fixed inside the fixing plate 2 by two symmetrically arranged screws 5, ensuring that the pressure plate 4 continuously presses against one end of the pull rope 1, preventing it from coming loose. A rubber gasket is provided on the top surface of the pressure plate 4, which contacts the lower surface of one end of the pull rope 1 to prevent the pressure plate 4 from directly squeezing the pull rope 1. Wear and tear. A docking frame 6 is fixedly connected to the cover 3. A support plate 7 is fixedly connected inside the fixed plate 2. A limit frame 8 is fixedly connected to the support plate 7. The lower part of the limit frame 8 is inserted into the docking frame 6. The assembly and positioning of the cover 3 and the fixed plate 2 are achieved through the precise docking of the docking frame 6 and the limit frame 8. The pull rope 1 passes through the inside of the limit frame 8. A pressure block 9 is slidably set inside the limit frame 8. The bottom surface of the pressure block 9 is also provided with a rubber pad. An adjustment rod 10 is rotatably set on the top of the pressure block 9. The adjustment rod 10 passes through the limit frame 8 and rotates with the limit frame 8. A nut 11 is rotatably set on the upper part of the fixed plate 2. The nut 11 is threadedly engaged with the adjustment rod 10. The top of the adjustment rod 10 keeps in contact with the top of the nut 11. The pressure block 9 is located at a high position inside the limit frame 8 (that is, the pressure block 9 is not pressed tightly on the pull rope 1 at the beginning, so that the user can manually adjust the tightness of the pull rope 1 loop).

[0022] In the initial state, the pressure plate 4 continuously presses one end of the pull rope 1 under the action of the screw 5 to prevent one end of the pull rope 1 from coming out of the fixed plate 2. At this time, the pressure block 9 is in the high position of the limit frame 8 and does not apply pressure to the pull rope 1. The user can freely pull the outer end of the pull rope 1 to adjust the tightness of the ring formed by the pull rope 1. When the tightness is adjusted properly, the user rotates the nut 11 clockwise (with the top of the fixed plate 2 as the observation surface). Since the nut 11 is threadedly engaged with the adjusting rod 10, the rotation of the nut 11 is converted into the downward linear movement of the adjusting rod 10, which in turn drives the pressure block 9 to move down synchronously along the limit frame 8. The pressure block 9 then presses the pull rope 1 segment located below it, and locks the pull rope 1 through friction, thereby fixing the ring size.

[0023] If the tightness of the ring needs to be readjusted, rotate the nut 11 counterclockwise. The adjusting rod 10 will move the pressure block 9 upward, releasing the pressure on the pull rope 1. Then, the pull rope 1 can be pulled freely again to adjust the tightness. The whole process only requires rotation, which is simple and efficient.
