Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of liquid crystal television, especially relates to a fixed structure of adaptive assembly of liquid crystal television key unit. BACKGROUND

[0002] At present, the assembly of liquid crystal television is fixed through the mode of screw and catch, and the parts similar to key and the like which are used frequently usually require mechanical fixing such as screw to ensure the stable fixing of the whole key unit, but such structure usually comprises a plurality of different kinds of materials which are installed in stack to form an integral unit, and the shrinkage expansion coefficients of different materials are different in high-temperature or low-temperature environment, which often causes assembly interference or uneven gap between different materials, and affects the appearance quality and product life. SUMMARY

[0003] Technical scheme: in order to solve the above technical problems, the utility model provides a fixed structure of adaptive assembly of liquid crystal television key unit, and specifically comprises a key unit, a back plate, a limiting screw one and a rivet column;The fixed hole is arranged on the key unit support, the rivet column is arranged on the corresponding position of the back plate, the limiting screw one is installed in the fixed hole, so that the back plate and the key unit are connected;Wherein the diameter d1 of the fixed hole is greater than the diameter d2 of the rivet column on the back plate.

[0004] As improvement, it further includes adaptive assembly structure, television shell and rear shell screw;The adaptive assembly structure is a reinforcing rib structure, is integrally formed with the television shell, and is distributed around the key unit and abuts against the key unit;The television shell fixes the key unit through the rear shell screw.

[0005] As improvement, the adaptive assembly structure includes right side edge limiting rib, upper side edge limiting rib, left side edge limiting rib and lower side edge limiting rib four units, which are all non-enclosing limiting structures and are uniformly distributed around the key unit.

[0006] Beneficial effects: the fixed structure provided by the utility model does not need to change the present production process, and makes the television rear shell and the key unit adaptively cooperate by improving the fixing mode of the key and the mode of the television rear shell structure, improves the assembly gap, improves the appearance taste, and reduces the production cost. BRIEF DESCRIPTION OF DRAWINGS

[0007] Figure 1 It is the fixed structure structure schematic drawing of the utility model key unit.

[0008] Figure 2 It is the fixed structure structure schematic drawing of the utility model key unit.

[0009] Figure 3The utility model discloses a self-adaptive assembly structure's structural schematic diagram.

[0010] In the drawing: key unit 1, self-adaptive assembly structure 2, backplate 3, limit screw one 4, rivet column 5, right side edge limit rib position 21, upper side edge limit rib position 22, left side edge limit rib position 23, lower side edge limit rib position 24. DETAILED DESCRIPTION

[0011] The utility model discloses a self-adaptive assembly structure's structural schematic diagram.

[0012] As shown in Figure 1 The utility model provides a kind of fixed method of self-adaptive assembly of liquid crystal television key unit, and specifically includes key unit 1, backplate 3, limit screw one 4, rivet column 5;Fixed hole is set on the bracket of key unit 1, rivet column 5 is set on the corresponding position of backplate 3, and backplate 3 and key unit 1 are connected by installing limit screw one 4 in fixed hole;Wherein fixed hole diameter d1 is greater than the diameter d2 of rivet column 5 on backplate 3.This design makes key unit can be freely moved by the diameter of rivet column is less than the opening diameter of key unit.

[0013] Further, it further includes self-adaptive assembly structure 2, television housing 6, rear shell screw 7;Self-adaptive assembly structure 2 is reinforcing rib structure, and is integrally formed with television housing 6, and is distributed around key unit 1 and abuts against key unit 1;Television housing 6 fixes key unit 1 by rear shell screw 7.Through the design of rib structure, the size and position can be adjusted according to demand.

[0014] As shown in Figure 2 Self-adaptive assembly structure 2 includes right side edge limit rib position 21, upper side edge limit rib position 22, left side edge limit rib position 23, lower side edge limit rib position 24, and four rib positions are not surrounded limit structure, and are placed around key unit 1 respectively. Figure 3 As shown in

[0015] In the utility model, the fixed hole diameter of key unit bracket is greater than the diameter of fixed convex or rivet column on backplate, so that it can be freely moved in up-down and left-right directions, then using screw with larger head is fixed on rivet column to limit the movement of key unit in front-back direction, to prevent key unit from falling off.

[0016] In addition, a rib position is added on the TV rear shell assembled with the key unit, the gap between the key unit and the TV rear shell is controlled by adjusting the size of the rib position, and the assembly is more stable by fixing the TV rear shell to press the key unit.

[0017] Meanwhile, the key unit less affected by the ambient temperature is released and not forced to be fixed, so that it cannot be detached and can move freely, and the assembly gap and reliability are adjusted by adding a rib position on the rear shell which is easily affected by the ambient temperature, so that when the rear shell shrinks and expands due to the temperature, the key unit can automatically adjust the position with the shrinkage and expansion of the rear shell, and the overall appearance taste is guaranteed.

[0018] The above-mentioned embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application.
