[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] A universal assembly fixture for cover and backlight, referring to Figure 1 and Figure 2 , including a clamp base 10 , on which a receiving groove 11 for placing a cover plate 70 is opened, and the cover plate 70 is received in the receiving groove 11 .

[0025] Reference Figure 1 The clamp base 10 is rectangular in shape, and limiting columns for fixing the cover plate 70 are arranged on the four sides of the clamp base 10 . There are two limiting columns on each side of the clamp base 10 , and the plurality of limiting columns are used to fix the shape of the cover plate 70 .

[0026] Reference Figure 1The clamp base 10 is provided with a placement groove 12 relative to the position where the limiting column is placed. There are two placement grooves 12 on each side of the clamp base 10, so that multiple limiting columns are placed in the placement grooves 12 accordingly. The placement grooves 12 are opened toward the inside of the clamp base 10, and the placement grooves 12 are not connected to the receiving groove 11. The side of the placement grooves 12 away from the receiving groove 11 is connected to the outside. There are four types of limiting columns, namely the first limiting column 20, the second limiting column 30, the third limiting column 40 and the fourth limiting column 50. The four limiting columns can all be placed in the placement grooves 12. Different types of limiting columns are used to adapt to cover plates 70 with different external dimensions. The limiting columns are placed on the placement grooves 12 of the clamp base 10 to form a complete set of assembly clamps. In this embodiment, the structure of the clamp base 10 is different according to the shape of the cover plate 70 and the position of the limit column. Different clamp bases 10 can be provided with placement grooves 12 and limit columns to adapt to different shapes of the cover plate 70.

[0027] Further, refer to Figure 1 and Figure 2 , the length of the placement groove 12 is 28mm, the four types of limiting columns all include a seat body 60 and a support column 61 arranged on the seat body 60, the four types of limiting columns are all arranged in an inverted T shape, and the length of the seat body 60 of the four types of limiting columns is 28mm, so that the four types of limiting columns can be placed in the placement groove 12. The height of the seat body 60 of the four types of limiting columns is the same, which is 10mm. The height of the seat body 60 of the four types of limiting columns is the same as the thickness of the clamp base 10, so that the upper surface of the seat body 60 of the four types of limiting columns is flush with the upper surface of the clamp base 10. The lengths of the left and right edges of the seat body 60 of different types of limiting columns from the support column 61 are different, so that the outer edge of the cover plate 70 can be placed on the seat body 60 of the limiting column, and different types of limiting columns are replaced according to different outer dimensions of the cover plate 70. By setting a universal length of the placement slot 12 and a universal length of the limiting column seat 60 to match the placement slot 12, it is convenient to replace different types of limiting columns to match cover plates 70 with different external dimensions.

[0028] Reference Figure 3 The length between the left edge of the seat body 60 of the first limiting column 20 and the supporting column 61 is 1 mm, and the length between the right edge of the seat body 60 of the first limiting column 20 and the supporting column 61 is 2 mm.

[0029] Reference Figure 3 The length between the left edge of the seat body 60 of the second limiting column 30 and the supporting column 61 is 3 mm, and the length between the right edge of the seat body 60 of the second limiting column 30 and the supporting column 61 is 4 mm.

[0030] Reference Figure 3The length between the left edge of the seat body 60 of the third limiting column 40 and the supporting column 61 is 5 mm, and the length between the right edge of the seat body 60 of the third limiting column 40 and the supporting column 61 is 6 mm.

[0031] Reference Figure 3 The length between the left edge of the seat body 60 of the fourth limiting column 50 and the support column 61 is 7 mm, and the length between the right edge of the seat body 60 of the fourth limiting column 50 and the support column 61 is 8 mm.

[0032] Reference Figure 1 and Figure 2 When replacing a new cover plate 70, place the cover plate 70 in the receiving groove 11, select a limiting column that matches the outer dimensions of the cover plate 70 and place it in the placement groove 12, so that the outer edge of the cover plate 70 is located on the seat 60 of the limiting column, and the outer shape of the cover plate 70 is fixed by the support column 61 to complete the assembly. By setting different types of limiting columns and selecting matching limiting columns for cover plates 70 of different outer dimensions, the assembly fixture can be universal and can be adapted to cover plates 70 of different outer dimensions, without having to replace a new assembly fixture when replacing a new cover plate 70.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
