DETAILED DESCRIPTION

[0038] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] This embodiment shows an adjustable elastic blind plate suitable for different sizes of U positions, such as Figure 1-9 As shown, it includes a blind plate body 1,

[0040] The blind plate body 1 is provided with snap fasteners 2 symmetrically arranged on the left and right, and more than two pairs of limit grooves 6 symmetrically arranged on the upper and lower sides;

[0041] The blind plate body 1 is also provided with blocking grooves 3 on the upper and lower sides;

[0042] The elastic blind plate also includes an elastic stop bar 4 inserted into the stop bar groove 3 and limited in the limit groove 6;

[0043] The elastic retaining strip 4 has a latch 41 that is matched and connected with the limiting groove 6;

[0044] The left and right bottom sides of the elastic stop bar 4 are provided with elastic members 42 which can be inserted into the stop bar groove 3 . The elastic member 42 has a free end 421 which abuts against the bottom of the stop bar groove 3 .

[0045] Elastic blind plate in free state: the elastic baffle 4 is inserted into the baffle groove 3, the free end 421 of the elastic member 42 is against the bottom of the baffle groove 3, the elastic member 42 pushes the elastic baffle 4 outward, and the latch 41 cooperates with the limiting groove 6 to limit the further outward movement distance of the elastic baffle 4, so that the elastic blind plate is limited to a certain height in the free state.

[0046] Elastic blind plate in compressed state: The elastic blind plate in free state presses the elastic baffle 4 to make the elastic baffle 4 move further inward in the limit groove 6 and the baffle groove 3, thereby compressing the elastic member 42, so that the height of the elastic blind plate is temporarily reduced.

[0047] Assembly process of elastic blind plate height = U-position height:

[0048] Take the installation of the elastic blind plate described in this application in the U position of the cabinet in the same row as an example: Figure 3and Figure 6 As shown, a plurality of elastic blind plates in a free state are respectively aligned with the square holes corresponding to the U positions of the cabinet by means of their respective snap fasteners 2 and are snap-fastened, without the need to press the elastic stop strips 4 to adjust the height of the blind plates.

[0049] Assembly process of elastic blind plate height > U-position height:

[0050] For example, if the standard U-position height is 44.45 mm, the elastic blind plate of the present application is 46.45 mm high in the free state, and the elastic blind plate height is greater than the standard U-position height. Taking the installation of the elastic blind plate described in the present application in the U-position of the cabinet in the same row as an example: Figure 5-7 As shown, for example, the elastic blind plate is installed from bottom to top, and the snap-fitting piece 2 of the first elastic blind plate is aligned with the square hole corresponding to the U position of the cabinet to be snap-fitted;

[0051] Use the elastic stopper 4 of the second elastic blind plate to squeeze the elastic stopper 4 of the first elastic blind plate to temporarily reduce the height of the elastic blind plate, so as to ensure that the buckle 2 of the second elastic blind plate can be aligned with the square hole corresponding to the U position of the cabinet for buckle fixing;

[0052] Continue to assemble other flexible blind plates according to this step as needed.

[0053] In the present application, the elastic blind plate in the compressed state can adapt to the standard high U position or the U position slightly exceeding the standard height, and the elastic blind plate in the free state can adapt to the U position exceeding the standard height. In the present application, an elastic blind plate can adapt to cabinets with U positions of different sizes and has strong compatibility.

[0054] For example, Figure 7 As shown, the elastic retaining strip 4 has an avoidance groove 43 on the outer side of the latch 41 , and the free end 421 of the elastic member 42 falls into the avoidance groove 43 when under pressure, compressing the elastic member 42 so that the height of the elastic blind plate is temporarily reduced.

[0055] For example, Figure 2-5 As shown, the cross-section of the elastic stop strip 4 is T-shaped with a wider upper part and a vertical lower part. The elastic member 42 is provided at the T-shaped lower part. In the free state, the free end 421 pushes the bottom of the stop strip groove 3, and the elastic member 42 pushes the T-shaped lower part of the elastic stop strip 4, so that the elastic blind plate is limited to a certain height in the free state.

[0056] The T-shaped upper portion can abut against other elastic blind plates adjacent thereto and press the free end 421 to adjust the height of the elastic blind plate to be temporarily reduced.

[0057] This embodiment shows one of the T-shaped upper parts, such as Figure 2 and Fig. 9 As shown, the upper cross-section of the T-shape is triangular.

[0058] This embodiment shows another T-shaped upper part, which is not shown in the figure, and the cross-section of the T-shaped upper part is rectangular.

[0059] It should be noted that the T-shaped upper portion is not limited to the cross-section of the triangle or rectangle as described in the embodiment, and a square or semicircular shape may also be implemented similarly.

[0060] For example, Figure 5-6 As shown, the buckle 2 is used to buckle and fix with the square hole 51 of the cabinet U position 5, and includes a front plug tongue 21, a side plug tongue 22 and a rear plug tongue 23.

[0061] This embodiment shows one of the side plug tongues, which are not shown in the figure. The side plug tongue 22 is a spring piece that tilts outward from the back to the front. The side plug tongue 22 tilted outward is adjusted so that the buckle 2 can pass through the square hole 51, and then the square hole 51 is opened by the side plug tongue 22 to achieve buckle fixation. When disassembling, a certain external force is applied behind the U position 5 to pull out the buckle 2.

[0062] This embodiment shows another side tongue, such as Figure 5-6 As shown, the side tongue 22 is a spring piece with one end fixed to the blind plate body 1, extending and bending back to have an adaptive surface 221 and a back pressure surface 222. When the adaptive surface 221 is close to the square hole 51, the buckle 2 is further pressed, and the adaptive surface 221 is squeezed inward and adaptively passes through the square hole 51, and then the back pressure surface 222 back-presses the square hole 51 to achieve buckle fixation. When disassembling, a certain external force is applied behind the U position 5 to pull out the buckle 2.

[0063] The utility model uses the fastener 2 to realize quick and convenient installation or removal of the blind plate.

[0064] For example, Figure 3-5 As shown, the U bit includes at least one of 1U high U bit, 1U+1 high U bit and 1U+2 high U bit.

[0065] For example, Figure 3-5 As shown,

[0066] If the height of the 1U high U position is 44.45mm, Figure 5 As shown, the elastic stop bar 4 needs to be pressed with great force and assembled into the square hole corresponding to the U position of the cabinet;

[0067] If the height of 1U+1 high U position is 45.45mm, Figure 4 As shown, the elastic stop bar 4 needs to be pressed and assembled into the square hole corresponding to the U position of the cabinet;

[0068] If the height of 1U+2 high U position is 46.45mm, Figure 3 As shown, the elastic stop strip 4 can be directly assembled in the square hole corresponding to the U position of the cabinet without pressing.

[0069] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
