Description

Technical Field

[0001] The present invention relates to the technical field of buckles, and in particular to a buckle structure, and more particularly to a buckle structure for connecting a buckle ring on a pet collar. Background Art

[0002] In today's society, it is very common for families to keep pets, among which cats and dogs are the most common pets. When people go out to walk their pets, in order to prevent the pets from getting lost or accidentally hurting people, a leash that restricts the pet's movement becomes an indispensable tool. The leash is generally connected to the buckle on the pet's collar through a buckle to restrict the pet's movement. However, in the buckles of the existing pet leash buckles, the contact point between the movable bolt and the hook-shaped buckle body is too close to the opening of the hook-shaped buckle body, which makes it difficult to insert the buckle on the collar into the buckle. For people with poor eyesight, or in the morning and evening when the vision is poor, or when the dog is actively jumping, it is even more difficult to insert the buckle on the collar, which is very inconvenient to use, especially for the elderly. Moreover, because the contact point between the movable bolt and the hook-shaped buckle body is too close to the opening of the hook-shaped buckle body, at certain angles, the buckle can detach from the hook-shaped buckle body and surround the movable bolt, such as Figure 1 and Figure 2 When the pet exerts force, the buckle on the collar will push the movable bolt, which may cause it to slide out of the buckle directly, or the buckle may push the switch of the movable bolt and slide out of the buckle. Therefore, there is a risk and probability of slipping out, which poses a safety hazard. Summary of the invention

[0003] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a buckle structure which is easy to use and safe.

[0004] The technical solution adopted by the present invention to solve the technical problem is:

[0005] A buckle structure includes a hook-shaped buckle body and a movable bolt, the hook-shaped buckle body includes a question mark-shaped main body and a blocking section arranged at the upper end of the question mark-shaped main body, an opening is formed between the lower end of the blocking section and the question mark-shaped main body, the lower end of the movable bolt is hinged to the lower end of the question mark-shaped main body, a reset device is provided between the movable bolt and the question mark-shaped main body, the upper end of the movable bolt elastically contacts the upper end of the question mark-shaped main body, a accommodating cavity is formed between the movable bolt and the question mark-shaped main body, and the blocking section is located outside the accommodating cavity.

[0006] As an improvement of the above technical solution, the upper end of the blocking section and the upper end of the question mark-shaped body are smoothly connected, and the middle part of the blocking section is bent toward the direction close to the question mark-shaped body.

[0007] As an improvement of the above technical solution, the lower end of the blocking section is bent in a direction away from the question mark-shaped main body.

[0008] As an improvement of the above technical solution, the upper end of the movable bolt is bent toward the upper end of the question mark-shaped body.

[0009] As an improvement of the above technical solution, the movable bolt includes a bolt body and a limit block arranged at the upper end of the bolt body, the lower end of the bolt body is hinged to the question mark-shaped body, the upper end of the bolt body is elastically in contact with the question mark-shaped body, the limit block is connected to one side of the bolt body close to the question mark-shaped body, and a limit groove is correspondingly provided on the question mark-shaped body, and the limit groove can accommodate the limit block.

[0010] As an improvement of the above technical solution, a handle is provided on the side of the upper end of the bolt body.

[0011] As an improvement of the above technical solution, a portion of the handle protrudes from the space surrounded by the question mark-shaped body and the blocking section.

[0012] As an improvement of the above technical solution, a connecting block is provided at the lower end of the bolt body, a first pin hole is provided on the connecting block, and a second pin hole is correspondingly provided at the lower end of the question mark-shaped body. The movable bolt and the question mark-shaped body are connected by a pin shaft passing through the first pin hole and the second pin hole, and the movable bolt can rotate relative to the pin shaft.

[0013] As an improvement of the above technical solution, the reset device is a torsion spring, which is sleeved on the pin shaft, one end of the torsion spring abuts against the movable bolt, and the other end of the torsion spring abuts against the question mark-shaped body.

[0014] As an improvement of the above technical solution, a storage groove is opened at the lower end of the question mark-shaped body, and the reset device is placed in the storage groove.

[0015] The beneficial effects of the present invention are:

[0016] The hook-shaped buckle body of the buckle structure includes two parts: a question mark-shaped main body and a barrier section. The upper end of the movable bolt is elastically in contact with the upper end of the question mark-shaped main body, that is, the contact point between the movable bolt and the hook-shaped buckle body is located in the middle of the hook-shaped buckle body, and the barrier section is located outside the accommodating cavity formed by the movable bolt and the question mark-shaped main body. In this way, when installing the buckle into the buckle structure, the buckle can be easily installed on the buckle structure by simply putting the buckle on the barrier section and moving the buckle in the direction of the accommodating cavity. In other words, the barrier section can assist the buckle in being introduced into the accommodating cavity, which greatly facilitates the introduction and installation of the buckle into the buckle structure. Moreover, the barrier section is located outside the accommodating cavity, which can prevent the buckle from sliding off the hook-shaped buckle body, and the stopper cannot surround the movable bolt. In this way, no matter how much force is applied to the buckle, the buckle cannot push the movable bolt, so that the buckle will not slide out of the buckle structure, eliminating the risk and probability of the buckle sliding out, and is safe to use.

[0025] See also Figure 3 and Figure 4 A buckle structure of the present invention includes a hook-shaped buckle body 1 and a movable bolt 2. The hook-shaped buckle body 1 includes a question mark-shaped main body 11 and a blocking section 12 arranged at the upper end of the question mark-shaped main body 11, an opening 13 is formed between the lower end of the blocking section 12 and the question mark-shaped main body 11, the lower end of the movable bolt 2 is hinged to the lower end of the question mark-shaped main body 11, a reset device 3 is provided between the movable bolt 2 and the question mark-shaped main body 11, the upper end of the movable bolt 2 elastically contacts the upper end of the question mark-shaped main body 11, a accommodating cavity 4 is formed between the movable bolt 2 and the question mark-shaped main body 11, and the blocking section 12 is located outside the accommodating cavity 4.

[0026] See Figure 5 The question mark-shaped main body 11 and the barrier section 12 are an integrated structure. The question mark-shaped main body 11 includes an upper curved section 111, a middle inclined section 112 and a lower vertical section 113. An inclined long strip space 114 is formed between the barrier section 12 and the curved section 111 and the inclined section 112. The vertical length of the long strip space is greater than the horizontal width. The opening 13 and the accommodating cavity 4 are both part of the long strip space 114.

[0027] Moreover, the upper end of the blocking segment 12 is smoothly connected to the upper end of the question mark-shaped body 11, the middle portion of the blocking segment 12 is bent toward the direction close to the question mark-shaped body 11, and the lower end of the blocking segment 12 is bent toward the direction away from the question mark-shaped body 11. In this embodiment, the upper end of the blocking segment 12 is smoothly connected to the curved segment 111, the middle portion of the blocking segment 12 is bent toward the direction close to the inclined segment 112, and the lower end of the blocking segment 12 is bent toward the direction away from the inclined segment 112. Of course, there may be other situations, for example, the middle portion of the blocking segment 12 is bent toward the direction close to the vertical segment 113, and the lower end of the blocking segment 12 is bent toward the direction away from the vertical segment 113.

[0028] In this way, along the direction of the buckle being introduced into the accommodating cavity 4, the opening 13 is first larger and then smaller. The first larger is to facilitate the buckle to enter the opening, and the latter smaller is to reduce the probability of the buckle slipping out of the accommodating cavity 4. In addition, the lower end of the blocking section 12 is bent in a direction away from the question mark-shaped main body 11, which can also better prevent the buckle from sliding off the hook-shaped buckle body 1.

[0029] See also Figure 4 The upper end of the movable bolt 2 is bent toward the upper end of the question mark-shaped body 11 to form a blocking section 25. One end of the blocking section 25 is in elastic contact with the curved section 111. The blocking section 25 and the curved section 111 are perpendicular to each other at the contact point. The movable bolt 2 includes a bolt body 21 and a limit block 22 provided at the upper end of the bolt body 21. The lower end of the bolt body 21 is hinged to the question mark-shaped body 11. The upper end of the bolt body 21 is the blocking section 25. The design of the blocking section 25 enables the buckle ring to apply a thrust to the movable bolt 2 from the accommodating cavity 4 at the contact position between the movable bolt 2 and the hook-shaped buckle body 1. The thrust direction is always in the direction of pushing the movable bolt 2 closer to the hook-shaped buckle body 1, that is, the thrust direction is in the direction of locking the movable bolt 2. The buckle ring cannot be squeezed out of the movable bolt 2, which can effectively prevent the buckle ring from being detached from the buckle structure.

[0030] See also Figure 6 and Figure 7 The limit block 22 is connected to the side of the bolt body 21 close to the question mark-shaped main body 11, specifically, the limit block 22 is connected to the side of the bolt body 21 close to the inclined section 112, and the inclined section 112 is correspondingly provided with a limit groove 14, and the limit groove 14 can accommodate the limit block 22. In this embodiment, the limit block 22 is an inverted triangle, and the upper end surface of the inverted triangle is smoothly connected to the bolt body 21, and the limit groove 14 is a cube, and the notch of the limit groove 14 faces the long strip space 114.

[0031] In addition, a handle 23 is provided on the side of the upper end of the plug body 21. A portion of the handle 23 protrudes from the space surrounded by the question mark-shaped main body 11 and the blocking section 12. The handle 23 and the portion of the plug body 21 provided with the handle 23 are bent toward the inclined section 112, making it more comfortable for fingers to press the handle 23.

[0032] Furthermore, a connecting block 24 is provided at the lower end of the bolt body 21, and a first pin hole is provided on the connecting block 24. The shape of the connecting block 24 is a part of a circle, and the first pin hole is arranged at the center of the circle. A second pin hole 16 is correspondingly provided at the lower end of the question mark-shaped main body 11. The movable bolt 2 and the question mark-shaped main body 11 are connected by a pin shaft 5 passing through the first pin hole and the second pin hole 16, and the movable bolt 2 can rotate relative to the pin shaft 5.

[0033] Specifically, the vertical section 113 is provided with a storage groove 15, the notch of the storage groove 15 faces the long strip space 114, the storage groove 15 is connected with the limiting groove 14, the connecting block 24 and the lower part of the bolt body 21 are both located in the storage groove 15, the pin 5 passes through the storage groove 15, the reset device 3 is a torsion spring, the torsion spring is located in the storage groove 15, the torsion spring is sleeved on the pin 5, one end of the torsion spring abuts against the movable bolt 2, and the other end of the torsion spring abuts against the vertical section 113. The restoring force of the torsion spring causes the upper end of the movable bolt 2 to rotate in the direction of the blocking section 12 to seal the accommodating cavity 4, and the lower part of the bolt body 21 blocks the notch of the storage groove 15. The lower side of the storage groove 15 is an inclined surface 151, and the inclined surface 151 forms an obtuse angle with the bottom of the storage groove 15. Liquid or small debris falling into the storage groove 15 from the limiting groove 14 can fall from the lower end of the inclined surface 151 after the handle 23 is pressed toward the inclined section 112. The lower side of the bolt body 21 is also inclined accordingly.

[0034] In addition, the outer side of the lower end of the question mark-shaped main body 11, that is, the outer side of the vertical section 113, is provided with anti-slip grooves 19, which are multiple vertical protrusions. The lower end of the hook-shaped buckle body 1 is movably connected to an annular body 6, specifically, the lower end surface of the hook-shaped buckle body 1 is provided with a cylinder 17, and the lower end surface of the cylinder is provided with a limiting column 18. The annular body 6 is provided with a cylindrical hole, and the cylindrical body 17 is inserted into the cylindrical hole. The diameter of the cylindrical hole is smaller than the diameter of the limiting column 18.
