Description

Background Art

[0002] Nowadays, consumers pay more and more attention to the convenience and experience of use, improve product competitiveness, and enhance consumer experience. The connection between the current plastic bracket and the plastic chassis is usually fixed with a hook. To release the fixation of the two parts, the user needs to use his fingers to buckle the hook to release the fixation. Because the two parts must fit firmly, the hook is often required to fit more tightly, resulting in the user needing more force when he wants to release the two parts by buckling the hook with his fingers. The user's fingers will be very uncomfortable or even injured in this process. In addition, the user's fingers cannot buckle the hook because the hook fits too tightly, and can only buckle the hook with the help of other tools. The user experience is very poor. For this reason, we propose a connection structure between the plastic bracket and the plastic chassis. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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.

[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The present invention provides a technical solution: a plastic bracket and a plastic chassis connection structure, comprising a plastic bracket body 1 and a plastic chassis body 2, the top of the plastic chassis body 2 is provided with a connecting groove 4 with a cylindrical structure, and the bottom of the plastic bracket body 1 is integrally provided with a connecting seat 3 with a cylindrical structure, and the cooperation between the connecting seat 3 and the connecting groove 4 facilitates the clamping connection between the connecting seat 3 and the connecting groove 4.

[0025] The connecting seat 3 is connected in the connecting groove 4, and the inner wall of the connecting groove 4 is equidistantly provided with L-shaped clamping seats 6. The outer side of the connecting seat 3 away from one end of the plastic bracket body 1 is equidistantly provided with an arc-shaped clamping plate 5, and the arc-shaped clamping plate 5 is clamped in the L-shaped clamping seat 6. The bottom of the inner wall of the connecting groove 4 is provided with a locking component 21 for quickly clamping the plastic bracket body 1 on the plastic chassis body 2.

[0026] It should be noted that the arc-shaped clamping plate 5 is integrally arranged with the plastic bracket body 1, and the L-shaped clamping seat 6 is equidistantly arranged on the inner wall of the connecting groove 4. The three L-shaped clamping seats 6 are arranged symmetrically with the center. When the connecting seat 3 is clamped into the connecting groove 4, the arc-shaped clamping plate 5 and the L-shaped clamping seat 6 are staggered. After insertion, they are rotated at a certain angle so that the arc-shaped clamping plate 5 is clamped inside the L-shaped clamping seat 6, thereby realizing the connection between the connecting seat 3 and the connecting groove 4 on the plastic chassis body 2.

[0027] See also Figure 4 , Figure 5 , Figure 6 and Figure 7The locking assembly 21 includes a protruding plate 12 , the inner wall of the connecting seat 3 is integrally provided with the protruding plate 12 , and the end of the protruding plate 12 away from the plastic bracket body 1 is integrally provided with a locking plate 13 , and the bottom of the locking plate 13 is integrally provided with a locking block 14 .

[0028] It should be noted that the connecting seat 3 is inserted into the connecting groove 4 and rotated at a certain angle, and the arc-shaped clamping plate 5 is clamped in the L-shaped clamping seat 6. At this time, the locking block 14 at the bottom of the locking plate 13 is clamped between the protrusion 10 and the hook 9, so that the plastic bracket body 1 and the plastic chassis body 2 are clamped and fixed.

[0029] An arc-shaped groove 7 is provided at the bottom of the inner wall of the connecting groove 4, and an unlocking rod 8 is integrally provided on the inner wall at one end of the arc-shaped groove 7, a hook 9 is integrally provided on one side of the unlocking rod 8 located inside the connecting groove 4, and a protrusion 10 is integrally provided on the bottom of the inner wall of the connecting groove 4 located outside the arc-shaped groove 7, and a locking block 14 is clamped between the protrusion 10 and the hook 9.

[0030] It should be noted that when the present invention is used, the connecting seat 3 at the bottom end of the plastic bracket body 1 is correspondingly inserted into the connecting groove 4 on the plastic chassis body 2, so that the arc-shaped card plate 5 on the connecting seat 3 is correspondingly inserted between the two adjacent L-shaped card seats 6 in the connecting groove 4, and the locking plate 13 is placed at the position of the arc-shaped ramp plate 11. After insertion, the plastic bracket body 1 is rotated clockwise. After rotating a certain angle, the locking block 14 at the bottom of the locking plate 13 is clamped between the protrusion 10 and the hook 9 to make it engaged and connected. When the plastic bracket body 1 needs to be disassembled, it is only necessary to press the pressing block 17 at the end of the unlocking rod 8 at the bottom of the plastic chassis body 2 to make the hook 9 push the end of the locking plate 13 toward the inside of the connecting groove 4. The bottom height of the locking block 14 is located above the protrusion 10, and then it is rotated counterclockwise for a certain angle to release the engagement, and the plastic bracket body 1 can be directly pulled out.

[0031] See also Figure 5 Two arc-shaped ramp plates 11 are integrally provided on one side of the protrusion 10 away from the arc-shaped groove 7 .

[0032] It should be noted that during the rotation process after the connecting seat 3 is connected to the connecting groove 4, the locking block 14 slides toward the arc-shaped ramp plate 11, and slides through the arc-shaped ramp plate 11 to be clamped between the protrusion 10 and the hook 9, thereby realizing the clamping connection between the plastic bracket body 1 and the plastic chassis body 2.

[0033] See also Figure 4 The end of the locking plate 13 is provided with a second inclined surface 16 that cooperates with the arc-shaped ramp plate 11, and the end of the locking block 14 is provided with a first inclined surface 15 that cooperates with the arc-shaped ramp plate 11.

[0034] It should be noted that after the locking block 14 slides onto the arc-shaped ramp plate 11 , the second inclined surface 16 at the bottom of the locking block 14 slides on the arc-shaped ramp plate 11 , making the connection and disassembly process smoother and reducing the friction and difficulty that may occur during operation.

[0035] See also Figure 8 A pressing block 17 is integrally provided at the end of the unlocking rod 8 located on one side outside the plastic chassis body 2 , and the bottom plane of the pressing block 17 is located above the bottom plane of the plastic chassis body 2 .

[0036] It should be noted that the pressure block 17 is integrally arranged on the unlocking rod 8. When the pressure block 17 is pressed, the unlocking rod 8 can be pressed toward the inside of the connecting groove 4, and the hook 9 on the unlocking rod 8 lifts the locking plate 13, so that the locking block 14 on the locking plate 13 is away from the arc groove 7. During the rotation of the plastic bracket body 1, the locking block 14 slides down along the arc-shaped ramp plate 11, so that there is no locking structure between the plastic bracket body 1 and the plastic chassis body 2, and the plastic bracket body 1 can be directly pulled out.

[0037] See also Figure 8 An arc-shaped double-way arrow 18 is arranged outside the arc-shaped groove 7 at the bottom of the plastic chassis body 2, and an unlocking mark 19 and a locking mark 20 are arranged at both ends of the arc-shaped double-way arrow 18 at the bottom of the plastic chassis body 2, and the locking mark 20 is located at one end of the pressing block 17.

[0038] It should be noted that the arc-shaped bidirectional arrow 18 can indicate the direction of the connection rotation. When the plastic bracket body 1 is fixed, it rotates toward one end of the locking mark 20, and when unlocked, it rotates toward one end of the unlocking mark 19.

[0039] See also Figure 5 The three L-shaped card seats 6 are centrally symmetrically arranged, and the three L-shaped card seats 6 and the plastic chassis body 2 are an integrated structure.

[0040] It should be noted that the integrated structure of the L-shaped card holder 6 and the plastic chassis body 2 reduces the gaps between components, saves space, and avoids redundant connectors and components, which helps to improve the compactness of the product and reduce the overall weight.
