DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] See also Figures 1 to 3 The utility model provides a glass cover positioning tool, comprising:

[0024] The positioning bracket 1 has a first end 101 and a second end 102 which are perpendicular to each other;

[0025] Three adjustment brackets are slidably connected in sequence, and the three adjustment brackets are configured as an adjustment module, and the first and second ends of the adjustment module are respectively slidably matched with the first end 101 and the second end 102 of the positioning bracket 1;

[0026] An adjustment assembly, comprising a meshing gear 6 and a rack 7, and a threaded rod 8 connected to the gear 6, wherein the rack 7 is arranged along the sliding direction of one of the adjustment brackets, the threaded rod 8 is passed through the other adjustment bracket and extends to the first end 101 of the positioning bracket 1, and the rack 7 is perpendicular to the axis of the threaded rod 8;

[0027] Among them, a fixed cavity 2 is constructed between the positioning bracket 1 and the adjustment module, and the fixed cavity 2 has a length direction and a width direction. The rack 7 and the threaded rod 8 are respectively arranged in the length direction and the width direction of the fixed cavity 2, and are used to link the corresponding adjustment bracket to approach or move away from the positioning bracket 1.

[0028] In this embodiment, a fixed cavity 2 is formed between the positioning bracket 1 and the adjustment module. The fixed cavity 2 is used to limit the glass cover plate so as to fit and assemble with the mobile phone. The fixed cavity 2 has a length direction and a width direction. The rack 7 and the threaded rod 8 are respectively arranged along the length direction and the width direction. By rotating the threaded rod 8, the meshing action of the gear 6 and the rack 7 can pull the corresponding adjustment bracket to move relatively, so that the positions of the adjustment bracket and the positioning bracket 1 can be adjusted to abut against glass cover plates of different sizes; the positioning bracket 1 has a first end 101 and a second end 102 that are perpendicular to each other. The three adjustment brackets are sequentially slidably connected to form an adjustment module. The head and tail ends of the adjustment module are respectively slidably matched with the first end 101 and the second end 102 of the positioning bracket 1. At the adjustment bracket at the head end, there are a meshing gear 6 and rack 7, and a threaded rod 8 connected to the gear 6. The threaded rod 8 is threadedly disposed through the adjustment bracket at the head end and connected to the first end 101 of the positioning bracket 1. The rack 7 and the threaded rod 8 are respectively disposed along the length direction and the width direction of the fixed cavity 2. By rotating the threaded rod 8, the adjustment bracket at the head end moves closer to the first end 101 of the positioning bracket 1, and the adjustment bracket in the middle moves closer to the adjustment bracket at the end. At this time, the gear 6 rotates synchronously and meshes with the rack 7, driving the adjustment bracket in the middle to move closer to the adjustment bracket at the head end, and the adjustment bracket at the end moves closer to the second end 102 of the positioning bracket 1, so as to realize the synchronous adjustment of the length and width of the fixed cavity 2, so as to quickly limit glass cover plates of different sizes and facilitate assembly.

[0029] Define the adjustment bracket at the head end 3 among the three adjustment brackets as the head-end adjustment bracket 3 close to the first end 101 of the positioning bracket 1, the adjustment bracket at the end 5 close to the second end 102 of the positioning bracket 1 as the end-end adjustment bracket 5, and the adjustment bracket in the middle 4 between the head-end adjustment bracket 3 and the end-end adjustment bracket 5 as the middle adjustment bracket 4. The rack 7 is fixed to the middle adjustment bracket 4, and the threaded rod 8 is disposed through the head-end adjustment bracket 3.

[0030] In this embodiment, when the threaded rod 8 is rotated, the gear 6 will rotate accordingly and mesh with the rack 7. Since the rack 7 is fixed to the middle adjustment bracket 4, the linear motion of the rack 7 will be converted into the sliding of the middle adjustment bracket 4. At the same time, since the head-end adjustment bracket 3 is penetrated by the threaded rod 8, the rotation of the threaded rod 8 will also directly push the head-end adjustment bracket 3 to slide in the direction of the first end 101 of the positioning bracket 1. By simply rotating the threaded rod 8, the length and width of the fixed cavity 2 can be adjusted simultaneously, which not only improves the work efficiency, but also enhances the flexibility and accuracy of the positioning tooling.

[0031] The head-end adjustment bracket 3 is provided with a guide groove 9 along the sliding direction of the middle adjustment bracket 4, and the rack 7 is slidably disposed in the guide groove 9.

[0032] In this embodiment, a guiding groove 9 is provided on the head-end adjusting bracket 3, and its direction is the same as the sliding direction of the middle-end adjusting bracket 4. This guiding groove 9 is used to guide the sliding of the rack 7 to ensure that the movement track of the rack 7 in the linear direction is accurate and error-free.

[0033] The rack 7 is provided with a guiding protrusion 701 adapted to the guiding groove 9, and the guiding protrusion 701 is slidably arranged in the guiding groove 9.

[0034] In this embodiment, the rack 7 is provided with a guiding protrusion 701 matching the guiding groove 9. When the rack 7 slides, the guiding protrusion 701 is in close contact with the side wall of the guiding groove 9, which plays a role in restricting the lateral movement of the rack 7 and ensures that the rack 7 can only slide along the linear direction of the guiding groove 9.

[0035] A matching first connecting rod 10 and first connecting hole 11 are provided between the head-end bracket and the middle-end bracket and between the middle-end bracket and the tail-end bracket, and the first connecting rod 10 slidably extends into the first connecting hole 11.

[0036] In this embodiment, between the head-end bracket and the middle-end bracket, and between the middle-end bracket and the tail-end bracket, the matching mode of the first connecting rod 10 and the first connecting hole 11 is adopted to realize the sliding connection between the brackets, ensuring the stability and coherence of the adjustment of each bracket during sliding.

[0037] A matching second connecting rod 12 and second connecting hole 13 are provided between the tail-end bracket and the second end 102 of the positioning bracket 1, and the second connecting rod 12 slidably extends into the second connecting hole 13.

[0038] In this embodiment, the sliding connection of the second connecting rod 12 and the second connecting hole 13 is adopted between the tail-end bracket and the second end 102 of the positioning bracket 1, echoing the connection mode between the head-end bracket and the middle-end bracket, jointly constructing a complete, highly flexible and stable positioning tooling system, which is suitable for various high-precision glass cover plate assembly and positioning tasks.

[0039] A positioning block 14 extends inwards from the inner wall of the fixed cavity 2 to form a limiting step surface.

[0040] In this embodiment, when the glass cover plate is placed in the fixed cavity 2, its edge contacts the limiting step surface, ensuring the precise positioning of the glass cover plate in the length and width directions, preventing unnecessary displacement during the movement of the adjusting bracket. Through the close contact with the limiting step surface, the position of the glass cover plate is fixed, thus ensuring the accuracy and consistency during subsequent assembly.

[0041] The positioning bracket 1 and the adjusting bracket are in an L-shaped structure.

[0042] In this embodiment, the size and angle of the L-shaped structure can be adjusted according to the specific size of the glass cover plate to ensure the best support effect and positioning accuracy.

[0043] The positioning bracket 1 is provided with a stop block 15.

[0044] In this embodiment, the stop block 15 can prevent unnecessary movement of the positioning bracket 1. When the other three adjusting brackets adjust the length and width, the immobility of the positioning bracket 1 can provide additional stability.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
