[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] Embodiment

[0022] See Figures 1-3 as shown:

[0023] The present utility model provides a thin snap fastener, including: an object A to be snap-connected, a fixing block 10, and a snap connection component 20.

[0024] The fixing block 10 is fixed on an object adjacent to the object A to be snap-connected; one end of the snap connection component 20 is rotatably connected to the fixing block 10, and the other end forms a snap connection with the object A to be snap-connected, so as to snap the object A to be snap-connected and the object provided with the fixing block 10 together to form a tight connection. The entire snap connection process is convenient and easy to operate. In addition, the connection between the entire snap connection component 20 and the fixing block 10 is detachable. When the snap connection component 20 needs to be repaired or replaced, only the snap connection component 20 needs to be disassembled and replaced, so there is no need to remove the fixing block 10, avoiding repeated installation of the fixing block 10, not only reducing the maintenance difficulty, but also being able to avoid losses between the fixing block 10 and the connected object caused by disassembly and assembly. Especially when installing furniture boards, the wear, looseness and abnormal noise at the connection between the metal part and the board caused by disassembly and assembly can be significantly reduced.

[0025] In specific applications, a U-shaped notch 11 is provided on the fixing block 10. The snap connection component 20 is mainly composed of a rotating shaft 21 and a C-shaped snap connector. There are two rotating shafts 21, which are respectively arranged on both sides of the C-shaped snap connector, and the two rotating shafts 21 are respectively axially connected to the connection holes 131 on the inner walls of both sides of the U-shaped notch 11. The depth of the U-shaped notch 11 can limit the rotation amplitude of the C-shaped snap connector, thereby avoiding excessive rotation of the C-shaped snap connector.

[0026] The snap connection component 20 further includes a spring 12. An installation hole 111 is provided in the U-shaped notch 11 of the fixing block 10. The C-shaped snap connector can be set into three parts in specific applications, a rectangular plate 22 and two quarter-circular plates 23. The two quarter-circular plates 23 are respectively connected to both sides of the rectangular plate 22 and jointly enclose a C-shaped snap plate. One end of the spring 12 is inserted into the installation hole 111, and the other end is in contact connection with the inner wall of a quarter-circular plate 23 of the C-shaped snap plate. The rotating shafts 21 are arranged at both ends of the rectangular plate 22.

[0027] With the above settings, during use, two quarter - circular arc plates 23, one is located in the U - shaped notch 11 to limit the rotation amplitude of the entire C - type clamping plate, and the other forms a clamping connection with the object A to be clamped. At the same time, under the extrusion force of the spring 12, it can prevent the entire C - type clamping plate from loosening after clamping, thus maintaining the stability of the entire buckle during use.

[0028] A through - hole 13 is provided on the fixed block 10. The through - hole 13 is used to install a connecting bolt 14. The connecting bolt 14 passes through the through - hole 13 to fix the fixed block 10 on an object adjacent to the object A to be clamped. And there are two through - holes 13, which are respectively located on both sides of the U - shaped notch 11.

[0029] During specific application, a groove with the same size as the fixed block 10 can be reserved in advance on the object where the fixed block 10 is installed. The fixed block 10 is fixed in the groove of the object through the connecting bolt 14, and then the clamping component 20 is installed, so as to avoid disassembling and assembling the fixed block 10 during the later maintenance of the clamping component 20, reduce the maintenance procedures, and improve the daily maintenance efficiency.

[0030] To facilitate the replacement of the entire C - type clamping plate, the connecting hole 131 is communicated with the through - hole 13. A notch for the installation and removal of the rotating shaft 21 is provided on the connecting hole 131. During actual use, the notch can be on both connecting holes 131 or only on one connecting hole 131, as long as it is convenient for the two rotating shafts 21 of the C - type clamping plate to be installed into the connecting hole 131.

[0031] During specific application, the nut of the connecting bolt 14 covers the notch. Thus, after the rotating shaft 21 is installed into the connecting hole 131, it can be restricted by the nut of the connecting bolt 14 to prevent it from falling out of the connecting hole 131. In addition, when the C - type clamping plate is deformed after long - term use, or when the extrusion force of the spring 12 on the C - type clamping plate fails and the spring 12 needs to be replaced, only slightly rotate the connecting bolt 14 to release the restriction of the nut of the connecting bolt 14 on the rotating shaft 21, and then the entire C - type clamping plate can be removed for replacement and repair.

[0032] To make the clamping between the entire C - type clamping plate and the object A to be clamped stable during actual use, the maximum distance between the two quarter - circular arc plates 23 of the C - type clamping plate can be equal to the sum of the thicknesses of the fixed block 10 and the object A to be clamped. Or a notch is opened on the contact surface between the object A to be clamped and the C - type clamping plate, so that after the entire C - type clamping plate and the object A to be clamped form a clamping connection, the entire contact surface is flatter, and it is not easy to shake between the two after clamping. Such a setting makes the buckle have a better use effect during application, especially when installing furniture, improving the flatness and stability of the connection.

[0033] It should be noted that if there are directional indications involved in the embodiments of the present utility model, such as up, down, left, right, front, back..., then the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture as shown in the drawings. If the specific posture changes, the directional indications will also change accordingly. In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

Taking "A and / or B" as an example, it includes scenario A, or scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, "a plurality of" means more than two. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist.
