Description

A screw-free installation structure

technical field

The utility model relates to a fast disassembling and fixing structure in the field of communication electronics, in particular to a screw-free simple and quick disassembling and fixing structure for components.

Background technique

Today's various communication and electronic devices are small in size and powerful in function, but they have high requirements for maintainability, which brings challenges to realize quick disassembly and fixation in an already compact space. Usually, parts are fixed by screws, rivets, rivets, welding, etc. The disadvantage of these methods is that equipment and tools are required for fixing and dismounting, and there is also room for operation, and even there is no way to disassemble. Therefore, in the case of tight equipment space and the need for quick tool-free disassembly and assembly, the above traditional methods are more difficult in advance, and cannot meet the requirements in many occasions.

Utility model content

The problem to be solved by the utility model is a screw-free installation structure capable of quick disassembly and assembly.

The technical solution adopted by the utility model is: the screw-free installation structure includes component one, component two and elastic elements, usually component one is a part that needs to be replaced frequently, component two is a mounting plate or a base, etc., and the elastic component is preferably a shrapnel , spring or thin steel plate, etc., the front end and/or rear end of the first component is provided with a lock tongue, and the second component is provided with a convex bridge corresponding to the position of the lock tongue, and the elastic element is fixed on the first component or the second component The front or rear end position is used to push and tighten component one after component one is loaded into component two.

The elastic element is preferably a "W"-shaped shrapnel, four vertical grooves are arranged on the front or rear end of the first or second assembly, and the "W"-shaped shrapnel is inserted into the four vertical grooves. After the groove, it is fixed under the effect of its own elastic force. Preferably, the openings of the two outermost vertical grooves in the four vertical grooves are smaller than the bottom to prevent the shrapnel from coming out.

The beneficial effects of the utility model are: the utility model pushes the lock tongue to be inserted into the convex bridge on the component two after putting the component one on the component two and deforms the elastic element, and the lock tongue is restricted by the convex bridge to realize up and down And the limit of the four degrees of freedom on the left and right, after loosening, the limit in the front and rear directions can be realized by pushing the elastic force after the deformation of the elastic element, so that the relative fixation of component 1 and component 2 can be realized. When component 1 needs to be disassembled, just Push component 1 in the opposite direction, so that the lock tongue on it is free from the restriction of the convex bridge, and the disassembly can be completed, which solves the problems of large space occupation, relying on tools, and inconvenient disassembly and assembly by traditional fixing methods, and can realize frequent needs such as dust-proof nets. The replaced parts do not need to be installed and replaced by any equipment or tools, and at the same time, a lot of internal space of the equipment can be saved.

Detailed ways

Now in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in Figure 1, the utility model takes the dust-proof net 1 which needs to be frequently disassembled as the first component as an example, and its front and rear ends are respectively provided with a deadbolt 11, as shown in Figure 2, the second component is the mounting plate 2, and the It is provided with a protruding bridge 21 corresponding to the position of the lock tongue of component 1 to limit the lock tongue. At the same time, the rear end is also provided with four vertical grooves 22 for clamping and fixing the elastic element 3. The outermost two vertical grooves The opening of the groove is smaller than the bottom to prevent the shrapnel from coming out. As shown in Figure 3, the elastic element 3 is a "W" shaped shrapnel, as shown in Figure 4, the elastic element 3 can be inserted into the four vertical grooves 22 to pass through The resilience of the elastic element 3 itself fixes it tightly on the component two 2 .

Figure 5 is a schematic diagram of the assembly of component one, component two, and elastic elements. During assembly, put component one 1 on component two 2, push component one 1, make it slide, and insert the lock tongue 11 into component two. The elastic element 3 is deformed in the convex bridge 21, and the lock tongue 11 is restricted by the convex bridge 21 to realize the four degrees of freedom of up and down and left and right. Limiting means that the relative fixation of component one and component two is achieved. When disassembling, you only need to push component one 1 in the opposite direction to make the front lock tongue on it break away from the restriction of the convex bridge, and then lift component one 1 upwards to remove it.
