Description

Technical Field

[0001] The utility model relates to the field of switch installation, in particular to a reinforced installation frame structure. Background Art

[0002] Electrical products such as switches and sockets need to be securely fixed to the installation box with screws. During the installation process, the mounting frame needs to withstand great force. Mounting frames made of plastic are not strong enough and are prone to aging and cracking. Mounting frames made of metal are not strong enough and are prone to deformation. After the bracket is deformed, there will be interference with the moving parts or uneven gaps, which will affect the appearance and performance of the product due to deformation during installation when it is finally used.

[0003] In order to optimize the performance of the mounting frame, a combination of plastic and metal materials is used. The two parts are stacked and subjected to force at the same time, but the deformation capacity of the two parts is inconsistent, which usually leads to a mismatch and uneven installation, affecting the appearance.

[0004] Therefore, the utility model provides a reinforced mounting frame structure to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A reinforced mounting frame structure, comprising:

[0007] A metal frame, wherein the metal frame is provided with symmetrically arranged mounting holes, the four corners of the metal frame are provided with sloped grooves, and the ends of the sloped grooves are provided with protrusions;

[0008] A plastic bracket, wherein the plastic bracket is provided with symmetrically arranged through holes, and also provided with symmetrically arranged convex strips along the center line of the through holes, and notches are provided at both ends of the convex strips;

[0009] The plastic bracket is stacked on the metal frame so that the mounting hole corresponds to the through hole and the convex block corresponds to the notch and abuts against the end of the convex strip.

[0010] A further solution is that a convex rib is arranged beside the mounting hole, and a reinforcing flange is arranged on the other side of the convex rib.

[0011] A further solution: the surface of the convex rib is a curved surface.

[0012] A further solution is that a side of the plastic bracket in contact with the metal frame is provided with a receiving groove matched with a reinforcing flange and a convex rib.

[0013] A further solution is that the four corners of the metal frame are also provided with spare installation holes, and the four corners of the plastic bracket are provided with spare through holes corresponding to the spare installation holes.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The metal frame and the plastic bracket are stacked, and the functional modules are installed on the plastic bracket. The metal frame bears the installation torque, and the through holes of the plastic bracket are only for screws to pass through and are not subjected to force, which can prevent the bracket from deforming and interfering with the functional module.

[0016] 2. The convex strip is engaged between the two convex blocks, and the reinforced flange and convex rib are located in the receiving groove, which can position the metal frame and the plastic bracket to prevent the metal frame and the plastic bracket from not fitting together, so that the two are combined into a whole, the structural performance is enhanced, and the thickness of the mounting frame will not be increased.

[0017] 3. The mounting frame can be overlapped on the side wall of the mounting box through the protrusions, which effectively increases the overlap length between the metal frame and the mounting box, prevents the metal frame from sinking into the mounting box due to the large opening of the mounting box, and makes the product unable to be installed. At the same time, it increases the strength of the metal frame and reduces the installation torque. BRIEF DESCRIPTION OF THE DRAWINGS

Slope grooves 15 are provided at the four corners of the metal frame 1, and a protruding block 16 is provided at the end of the slope groove 15. The block 16 can be connected to the slope groove 15 as a whole, and the thickness of the block 16 is consistent with the thickness of the slope bottom of the slope groove 15.

[0028] Furthermore, inner flanges are provided around the inner frame of the metal frame 1 , and the direction of the inner flanges is opposite to that of the reinforcing flanges 12 .

[0029] Furthermore, spare mounting holes 14 are provided at the four corners of the metal frame 1 .

[0030] See also Figure 3 The plastic bracket 2 is provided with a pair of symmetrically arranged through holes 21, and the positions of the through holes 21 correspond to the mounting holes 11. A convex strip 23 is also provided, which is symmetrically arranged along the center line of the through holes 21, and notches 24 are provided at both ends of the convex strip 23.

[0031] Furthermore, a receiving groove 25 is provided on the side of the plastic bracket 2 in contact with the metal frame 1 to cooperate with the reinforcing flange 12 and the rib 13. The surface of the rib 13 is an arc surface, which disperses the pressure received on the arc surface to the entire structure, thereby reducing the pressure at a single point.

[0032] Furthermore, spare through holes 22 corresponding to the spare mounting holes 14 are provided at four corners of the plastic bracket 2 .

[0033] See also Figure 4, the plastic bracket 2 is stacked on the metal frame 1, so that the mounting hole 11 corresponds to the through hole 21, the screw 4 passes through the through hole 21, the mounting hole 11 and the mounting box 3 are screwed together, and the outer cover 5 is covered on the plastic bracket 2. The mounting hole 11 bears the installation torque, and the through hole 21 is only for the screw to pass through, and is not subjected to force, so as to prevent the plastic bracket 2 from being deformed or cracked by force. At this time, the protrusion 16 is located in the corresponding notch 24, so that the convex strip 23 is engaged between the two protrusions 16, and the reinforcing flange 12 and the convex rib 13 are located in the accommodating groove 25, which can not only position the metal frame 1 and the plastic bracket 2 to prevent the metal frame 1 and the plastic bracket 2 from not fitting, but also can overlap the side wall of the mounting box 3 through the protrusion 16 to increase the strength of the metal frame 1 and reduce the installation torque deformation. The protrusion 16 can also increase the overlap length on the mounting box 3, so that the mounting frame can be installed on the mounting box 3 with a larger opening. The reinforcing flange 12 and the convex rib 13 are located in the receiving groove 25, which not only enhances the strength of the metal frame 1 but also avoids an increase in the thickness of the mounting frame.

[0034] The provision of the spare mounting holes 14 and spare through holes 22 provides the mounting frame with an additional spare mounting method. The mounting frame can also be directly mounted on the wall by screwing screws through the spare through holes 22 and screwing the spare mounting holes 14 .
