DETAILED DESCRIPTION

[0025] In order to facilitate understanding the utility model, the utility model will be described more comprehensively below with reference to relevant drawings, the drawings show several embodiments of the utility model, but the utility model can be realized by different forms, and is not limited to the embodiments described in the text, on the contrary, provide these embodiments are to make the disclosed content of the utility model more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on another element or there can be a middle element, when an element is referred to as "connected to" another element, it can be directly connected to another element or there can be a middle element, the terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs, the terms used in the specification of the utility model are for the purpose of describing specific embodiments, and are not intended to limit the utility model, the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] Embodiment one: please refer to the attached Figure 2 A middle frame support positioning jig, comprising:

[0029] The chassis board 1 is a flat plate structure and is used to support the bottom side of the middle frame support;The lower clamping groove 11 is evenly arranged on the upper end surface of the chassis board 1, so that the bottom side of the plurality of middle frame supports can be correspondingly clamped and limited;

[0030] The side vertical plate 2 is fixed to one side of the chassis board 1 and is used as a supporting piece of the upper shelf plate 3;

[0031] The upper frame plate 3, connected to the side upright plate 2 and parallel to the base frame plate 1, is used to support the upper edge of the middle frame bracket. The upper surface of the upper frame plate 3 has evenly spaced upper slots 31 for correspondingly locking and limiting the upper edges of multiple middle frame brackets. Figure 5 As shown, the lower slot 11 and the upper slot 31 correspond to each other and are aligned. The upper shelf plate 3 is U-shaped, and the middle part of the upper shelf plate 3 is connected to the side upright plate 2. The upper slot 31 is opened on both sides of the upper shelf plate 3.

[0032] In application, multiple mid-frame brackets are fitted onto the outside of the upper frame plate 3 and placed on the base frame plate 1. The upper edge of the mid-frame bracket is inserted into the upper slot 31, while the bottom side of the mid-frame bracket is inserted into the lower slot 11. A set of lower slot 11 and upper slot 31 realizes the individual limitation of the mid-frame bracket, which can improve the problem of mid-frame bracket shaking, reduce the generation of frictional foreign matter dust, and improve the backlight yield.

[0033] Example 2: The difference between this example and Example 1 is that:

[0034] like Figures 2-5 As shown, the upper shelf 3 is vertically connected to the side upright 2. Specifically, three vertically arranged limiting strips 21 are fixed on the side upright 2. The upper shelf 3 has a limiting groove 32 on the side facing the side upright 2, which corresponds to and is aligned with the limiting strips 21. The limiting groove 32 and the limiting strips 21 are fitted together to achieve a vertical connection. For the fastening structure, a fastening block 5 is fixed at the bottom of the upper shelf 3. The fastening block 5 has a threaded hole, and a fastening bolt 4 that abuts against the side upright 2 is connected in the threaded hole.

[0035] This allows the height of the upper plate 3 to be adjusted, making it suitable for different sizes of mid-frame brackets. It is highly versatile and can reduce the production losses of special fixtures.

[0036] Everything else is the same as in Example 1.

[0037] Example 3: The difference between this example and Example 2 is that:

[0038] like Figure 4 As shown, the side plate 2 has multiple fastening holes 22 along its height direction. The fastening holes 22 are threaded holes adapted to fastening bolts 4. This arrangement allows the upper frame plate 3 to be locked at multiple different height positions to accommodate various sizes of middle frame supports, and provides good fastening stability.

[0039] The rest is the same as in Example 2.

[0040] Example 4: The difference between this example and Example 2 is that:

[0041] like Figure 6As shown in the drawings, the upper end face of the bottom frame plate 1 is provided as an inclined lower inclined surface 12, and the inclination direction thereof is in the width direction of the lower clamping groove 11; the upper end face of the upper frame plate 3 is provided as an inclined upper inclined surface 33, and the inclination direction thereof is in the width direction of the upper clamping groove 31.

[0042] In the application, when the middle frame support is placed, the guiding effect of the lower inclined surface 12 and the upper inclined surface 33 makes the middle frame support have a downward moving tendency under the action of its own gravity, thereby facilitating the clamping of the middle frame support into the lower clamping groove 11 and the upper clamping groove 31.

[0043] The other is the same as Embodiment Two.

[0044] The above has described the utility model by way of example in connection with the drawings, and obviously the specific implementation of the utility model is not limited by the above manner, as long as this kind of non-essential improvement using the method concept and technical scheme of the utility model or directly applying the concept and technical scheme of the utility model to other occasions without improvement is within the protection scope of the utility model.
