Description

TECHNICAL FIELD

[0001] The utility model relates to the field of middle frame fixing, especially to a middle frame buckle mechanism of preventing falling off. BACKGROUND

[0002] In the design of traditional middle frame buckle mechanisms, screws or adhesives are usually used to connect the middle frame and the back shell. However, these traditional methods have many drawbacks in actual application. First of all, when the product is subjected to external forces such as impact, falling, etc., the screws or adhesives are prone to failure, causing the middle frame and the back shell to fall off or loosen, thereby affecting the overall stability and reliability of the product. This is particularly evident during long-term use, posing a safety hazard during use.

[0003] Secondly, the traditional fixing method is relatively cumbersome, requiring pre-tightening of the screws and then tightening with a wrench or other tool, which is time-consuming and labor-intensive. At the same time, the adhesives also need to be cured, increasing the production cycle. These factors make the assembly and maintenance process complex, reducing production efficiency. SUMMARY

[0004] The purpose of the utility model is to provide a middle frame buckle mechanism that prevents falling off to solve the problems raised in the background technology.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0008] One side of the fixed plate is fixed with a limiting block.

[0009] The protrusion and the groove formed on the lower side of the clamping block are in close sliding contact, which enables the clamping block to slide along the groove while maintaining close contact with the back shell when subjected to external force. In addition, the bottom of the clamping block is in close sliding contact with the fixed plate, which further ensures the stability and reliability of the clamping block during movement. One side of the fixed plate is also fixed with a limiting block, which plays a key role in the assembly process. When the back shell is combined with the middle frame, one side of the back shell will first come into close contact with the limiting block, and then the other side of the back shell will come into close contact with the protrusion of the clamping block as the assembly progresses. Because the side of the clamping block facing the limiting block is inclined, this design enables the back shell to gradually compress the compression spring and slide the clamping block inward during the pushing-in process. Once the back shell is fully in place, the elastic force of the compression spring will push the clamping block outward, making it tightly clamped into the reserved slot, thereby ensuring the stable connection between the middle frame and the back shell, effectively preventing the parts from falling off and loosening.

[0010] Preferably, the reserved slot and the clamping mechanism are provided with at least four groups.

[0011] Preferably, the protrusion and the groove are in close sliding contact.

[0012] Preferably, one side of the back shell is in close contact with the limiting block, and the other side is in close contact with the protrusion.

Embodiment 1

[0030] Reference Figures 1-8 A kind of anti-falling middle frame buckle mechanism, comprising: main screen 1, the lower side of main screen 1 is fixed with middle frame 2, the lower side of middle frame 2 is fixed with back shell 3, the outside of back shell 3 is equipped with reserved slot 4, the inside of middle frame 2 is fixed with buckle mechanism 5, buckle mechanism 5 is located in one side of reserved slot 4;Wherein

[0031] Buckle mechanism 5 includes fixed plate 51, the upper side of middle frame 2 is fixed with fixed plate 51, recess 52 is equipped on fixed plate 51, one side of fixed plate 51 is fixed with compression spring 53, one side of compression spring 53 is fixed with clamping block 54, the lower side of clamping block 54 is equipped with protruding block 55;And

[0032] One side of fixed plate 51 is fixed with limit block 56.

[0033] The protruding block 55 formed on the lower side of the clamping block 54 and the recess 52 form a close sliding relationship, this design makes the clamping block 54 can slide along the recess 52 when subjected to external force, while maintaining close contact with the back shell 3. In addition, the bottom of the clamping block 54 and the fixed plate 51 are in close sliding relationship, which further ensures the stability and reliability of the clamping block 54 during movement. One side of the fixed plate 51 is also fixed with a limit block 56, which plays a key role in the assembly process. When the back shell 3 is combined with the middle frame 2, one side of the back shell 3 will first contact the limit block 56, and then as the assembly proceeds, the other side of the back shell 3 will contact the protruding block 55 of the clamping block 54. Since the side of the clamping block 54 facing the limit block 56 is inclined, this design allows the back shell 3 to gradually compress the compression spring 53 during insertion, and the clamping block 54 to slide inward. Once the back shell 3 is in place, the spring force of the compression spring 53 will push the clamping block 54 to move outward, allowing it to tightly snap into the reserved slot 4, thereby ensuring a secure connection between the middle frame 2 and the back shell 3, achieving a secure connection between the middle frame 2 and the back shell 3, effectively preventing the parts from falling off and loosening.

[0034] Reserved slot 4 and buckle mechanism 5 are at least equipped and provided with four groups.

[0035] The protruding block 55 and the recess 52 are in close sliding relationship.

[0036] One side of the back shell 3 is in close contact with the limiting block 56, and the other side is in close contact with the protrusion 55.

[0037] The bottom of the clamping block 54 is in close sliding contact with the fixed plate 51.

[0038] The compression spring 53 is provided with at least two groups.

[0039] The side of the clamping block 54 facing the limiting block 56 is in an inclined structure.

[0040] Working principle: please refer to Figures 1-8 As shown, first of all, the design of this anti-falling middle frame buckle mechanism aims to ensure the stable connection between the middle frame 2 and the back shell 3. When assembling these components, the main screen 1 is fixed on the upper side of the middle frame 2, while the back shell 3 is fixed on the lower side of the middle frame 2. The outer side of the back shell 3 is pre-provided with reserved slots 4, which provide space for the installation and operation of the buckle mechanism 5. The core components of the buckle mechanism 5 include the fixed plate 51 fixed on the upper side of the middle frame 2, and the groove 52 opened on the fixed plate 51, which not only provides a track for the sliding of the clamping block 54, but also ensures that the clamping block 54 can move stably under the action of the compression spring 53. The compression spring 53 is fixed on one side of the fixed plate 51 and connected with the clamping block 54, providing an outward thrust for the clamping block 54, so that it can be tightly fitted in the reserved slot 4 of the back shell 3.

[0041] The ingenious design of the clamping block 54, with the protrusion 55 on its lower side in close sliding contact with the groove 52, allows the clamping block 54 to slide along the groove 52 while maintaining close contact with the back shell 3 when subjected to external force. In addition, the bottom of the clamping block 54 is in close sliding contact with the fixed plate 51, which further ensures the stability and reliability of the clamping block 54 during movement. One side of the fixed plate 51 is also fixed with a limiting block 56, which plays a key role in the assembly process. When the back shell 3 is combined with the middle frame 2, one side of the back shell 3 will first come into close contact with the limiting block 56, and then as the assembly progresses, the other side of the back shell 3 will come into close contact with the protrusion 55 of the clamping block 54. Due to the inclined structure of the side of the clamping block 54 facing the limiting block 56, this design allows the back shell 3 to gradually compress the compression spring 53 during the pushing-in process, and makes the clamping block 54 slide inward. Once the back shell 3 is in place, the elastic force of the compression spring 53 will push the clamping block 54 to move outward, making it tightly clamped into the reserved slot 4, thereby ensuring the stable connection between the middle frame 2 and the back shell 3, effectively preventing the parts from falling off and loosening. At the same time, at the contact point between the limiting block 56 and the back shell 3, professional glue can be added for bonding at this contact point, further increasing the overall structural strength.
