Description

Technical Field

[0001] The utility model relates to the field of installation and fixing of embedded instruments and meters, and in particular to an easily detachable annular buckle structure. Background Art

[0002] With the continuous progress of society and the continuous development of the times, the installation and fixing method of embedded instruments in daily life or work is usually to stick the panel of the instrument to the surface of the chassis, and then use screws to support the back of the chassis, so as to achieve the purpose of fixing the embedded instrument. However, this installation method is very cumbersome in the actual installation process of embedded instruments. First, the installer needs to snap the embedded instrument into the hollow chassis panel from the outside, and then the installer needs to fix the embedded instrument by tightening the screws on the back of the chassis. Since it is fixed on the back of the chassis surface, the installer needs to tighten the screws with his backhand, and the installer cannot use force in the process of tightening the screws, resulting in the screws not being completely tightened, and the embedded instrument may fall at any time, so this operation method is very inconvenient. Similarly, this installation method is also very inconvenient during disassembly. The disassembly personnel will also be unable to use force in the process of removing the screws because they are dismantled with their backhands, which increases the difficulty of disassembly.

[0003] At present, there are structures for installing embedded instruments, such as a Chinese patent with patent number CN206479570U that discloses an embedded instrument installation mechanism, in which slide grooves are opened on both sides of the four corners of the shell, and buckles are set in the slide grooves. The top of the buckle is an elastic structure, and the bottom of the buckle is engaged with the shell slot through the buckle teeth. The instrument is fixed by the buckle elastic structure. When dismantling such a design, the buckles at the four corners need to be removed separately to realize the removal of the instrument, which is difficult and troublesome to operate. Therefore, a structure with simple structure and easy to dismantle is urgently needed. Utility Model Content

[0004] The utility model provides an easily disassembled annular buckle structure, aiming to solve the problem that the existing structure for installing embedded instruments is troublesome to operate during disassembly.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an easily disassembled annular buckle structure, used for installing and fixing an embedded instrument on a chassis panel, comprising an annular buckle, an elastic module is arranged on the front end face of the annular buckle, hooks are arranged on two symmetrical sides of the annular buckle, protrusions are arranged on the end faces of the hooks facing each other, a plurality of slots are opened on both side faces of the shell of the embedded instrument, and the tail of the hook is bent outward to form a handle.

[0006] Further, the protrusion is a latching tooth inclined toward a side away from the elastic structure, and the direction of the latching groove is opposite to the direction of the latching tooth.

[0007] Furthermore, the elastic module includes ribs around the end surface of the annular buckle, and a strip-shaped gap is opened between the ribs and the annular buckle.

[0008] Furthermore, the latching teeth include at least two, the distance between the two latching teeth is 1.5 mm, and the tooth height of the latching teeth is 0.9 mm-1 mm.

[0009] Furthermore, the card slots include 8-12, the interval between two card slots is 1.5mm, and the depth of the card slots is 1mm-1.1mm.

[0010] Furthermore, the annular buckle is made of ABS+PC material.

[0022] Example

[0023] Reference Figure 1-2As shown, the utility model discloses an easily detachable annular buckle 20 structure, which is used for installing and fixing an embedded instrument 10 on a chassis panel, including an annular buckle 20, and an elastic module 203 is arranged on the front end face of the annular buckle 20. The elastic module 203 includes ribs around the end face of the annular buckle 20, and a strip-shaped gap is opened between the ribs and the annular buckle 20, and the strip-shaped gap provides a deformation space for the ribs. When installing, the embedded instrument 10 is inserted from the opening of the chassis panel, and the annular buckle 20 is inserted from the rear of the embedded instrument 10. When the annular buckle 20 is installed in place, the ribs are squeezed to deform them, providing a thrust pre-tightening effect to the annular buckle 20, so that the annular buckle 20 can be stably installed on the chassis panel.

[0024] Reference Figure 1-2 As shown, hooks are arranged on both sides of the annular buckle 20 symmetrically, and protrusions are arranged on the end faces of the hooks facing each other. A plurality of slots 101 are opened on both sides of the shell of the embedded meter 10, and the tail of the hook is bent outward to form a handle 202. Specifically, the protrusion is a tooth 201 inclined toward the side away from the elastic structure, and the direction of the slot 101 is opposite to the direction of the tooth 201. During installation, the embedded meter 10 is inserted from the opening of the chassis panel, and the annular buckle 20 is inserted from the tail of the embedded meter 10. When the annular buckle 20 is installed in place, the tooth 201 is stuck in the slot 101, so that the embedded meter 10 is fixed in the annular buckle 20. When the embedded meter 10 needs to be removed, the handle 202 is moved to make the tooth 201 disengage from the slot 101, and the embedded meter 10 can be taken out of the annular buckle 20. Compared with existing products on the market, the overall structure of the embedded meter 10 is simpler, and the installation and disassembly operations are convenient.

[0025] In this embodiment, there are at least two latch teeth 201, the spacing between the two latch teeth 201 is 1.5mm, and the tooth height of the latch teeth 201 is 0.9mm-1mm. The slots 101 include 8-12, the spacing between the two slots 101 is 1.5mm, and the groove depth of the slots 101 is 1mm-1.1mm. The spacing between the latch teeth 201 and the slots 101 is 1.5mm, because when the spacing between the latch teeth 201 is too small, the latch teeth 201 are easily damaged. At the same time, the tooth height of the latch teeth 201 is 0.9mm-1mm, and the groove depth of the slots 101 is 1mm-1.1mm, so that the latch teeth 201 can be completely clamped in the slots 101, avoiding the problem of loose clamping.

[0026] In addition, the annular buckle 20 is made of ABS+PC material. The front end of the annular buckle 20 supports the chassis panel, has a large elastic deformation, and is in a deformed state for a long time, which has high requirements for plastic materials. It is made of ABS+PC material, which greatly enhances flexibility and fatigue resistance. At the same time, the deformation of the elastic structure is adjusted, and it is not easy to deform and break even in the case of vibration.

[0027] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
