Embodiment two

In the fixing frame provided in this embodiment, the anti-deformation device is specifically an anti-deformation nut, and the fixing hole has a slot, and the anti-deformation nut is embedded in the slot. Please refer to FIG. 3 and FIG. 4 for details. FIG. 3 is a schematic structural view of a switch socket fixing frame provided by an embodiment of the present invention, and FIG. 4 is a front view and a top view of the fixing frame.

The edge of the fixed frame 30 is provided with a fixed hole 31, the fixed hole 31 runs through the upper and lower surfaces of the edge of the fixed frame 30, and the fixed hole 31 has a hole groove 311, the anti-deformation nut 50 is embedded in the hole groove 311, the anti-deformation nut 50 and the hole The grooves 311 are relatively movable, therefore, the anti-deformation nut 50 and the fixing frame 30 are separated.

The diameter of the fixing hole 31 matches the diameter of the locking screw 20 , so that the locking screw 20 can pass through the fixing hole 31 to fix the fixing frame 30 on the installation box 40 .

The screw hole diameter of the anti-deformation nut 50 is greater than or equal to the aperture of the fixing hole 31 , so that the locking screw 20 can pass through the anti-deformation nut 50 and then through the fixing hole 31 to fix the fixing frame 30 on the installation box 40 . The anti-deformation nut 50 may be an inner polygonal nut.

When the locking screw 20 fixes the fixing frame 30 on the installation box 40, it is screwed in to a certain extent, and the head of the locking screw 20 touches the fixing frame 30, and if it continues to be screwed in, the fixing frame 30 is pushed to be deformed, resisting The deformed nut 50 will also produce a corresponding inclination. When the inclination reaches the point where the screw thread interferes seriously with the screw thread of the locking screw 20, a self-locking phenomenon will occur. The locking screw 20 cannot be rotated, and the main frame of the fixing frame 30 will not be further deformed. The deformation of the fixing frame 30 can be reduced, and only the anti-deformation nut 50 is added, so the cost is low. Moreover, the fixing hole 31 is provided on the edge of the fixing frame 30. The fixing hole 31 is a through hole with a simple structure, and the processing process is relatively simple.

Further, the fixing hole 31 is provided with a tongue-shaped groove 312 , and the tongue-shaped groove 312 is formed on one side of the periphery of the fixing hole 31 . The tongue-shaped groove 312 can produce a small deformation, which is used to compensate for the amount of rotation pitch of the locking screw 20 , further reducing the deformation of the main frame of the fixing frame 30 .

Further, the anti-deformation nut 50 may specifically be a hexagonal nut. The hexagonal nut 50 is embedded in the hole 311 of the fixing hole 30, and when the locking screw 20 installs the fixing frame 30 to the installation box 40, a greater torque is applied to the locking screw 20, and the fixing frame 30 is deformed. As shown in Figure 5.

Further, the anti-deformation nut 50 may specifically be a round nut.

In this embodiment, because when the locking screw fixes the fixing frame on the installation box, it is screwed in to a certain extent, the head of the locking screw touches the fixing frame, and if it continues to be screwed in, the fixing frame is pushed to deform, preventing The deformed nut will also produce a corresponding inclination. When the inclination reaches the point where the thread and the thread of the locking screw are seriously interfered, a self-locking phenomenon will occur. The locking screw cannot be rotated, and the main frame of the fixing frame will not be further deformed, which can reduce the amount of the fixing frame. Deformation, and only anti-deformation nuts are added, the cost is low, and a fixing hole is provided on the edge of the fixing frame, the fixing hole is a through hole with a simple structure, and the processing process is relatively simple. Further, a tongue-shaped groove is provided on the periphery of the fixing hole. The anti-deformation nut is specifically a hexagonal nut. The locking screw first passes through the hexagonal nut embedded in the fixing hole, and then passes through the installation hole of the installation box. Since the fixing frame has an opening Tongue-shaped groove, so the hexagon nut can have appropriate movable space in the up, down, left, and right directions, and this movable space can be used to make up for the coaxiality error of the hexagon nut and the installation hole of the installation box and the difference in the number of pitch turns, so that The locking screw can smoothly pass through the hexagon nut and the installation hole of the installation box. After the locking screw is screwed into its head and contacts the fixed frame, the locking screw is integrated with the hexagon nut and basically stops rotating. When forced force is applied, the tongue-shaped groove of the fixing frame can produce a small deformation to compensate for the rotation pitch of the locking screw, so the main frame of the fixing frame will not deform further, thus further reducing the deformation of the fixing frame. Specifically, the anti-deformation nut can also be a round nut. The round nut becomes loose and rotatable during use. When the head of the locking screw touches the fixing frame, it continues to be screwed forward, pushing the tongue-shaped part of the fixing frame to deform, and at the same time The round nut will also have a corresponding inclination. When the round nut is inclined to the point where the thread interferes seriously with the thread of the locking screw, a self-locking phenomenon will occur, and the locking screw cannot be rotated. At this time, the deformation of the tongue-shaped groove is smaller than that of the round nut. The pitch of the screw, the main frame of the fixed frame will not be further deformed, thereby reducing the deformation of the fixed frame.

Embodiment three

Further, there is a slot 313 on the outer surface of the slot 311, the slot 313 is used to put the anti-deformation nut 50, and the lower edge of the slot 313 is provided with a rib 314, which is used to block the anti-deformation nut 50 from the slot. 313 came off.

Specifically, the anti-deformation nut 50 is a plastic part. It can be inserted into the hole groove 311 from the outer side of the hole groove 311 of the fixing hole 31 through the groove hole 313. The size of the groove hole 311 is larger than the size of the anti-deformation nut 50, which is convenient for placing the anti-deformation nut 50 in place, that is, the anti-deformation nut 50 Parallelly put into the hole 311 , so that the locking screw 20 can pass through the anti-deformation nut 50 smoothly.

Moreover, the anti-deformation nut 50 can move up, down, left, and right in the slot 311, and a rib 314 is provided on the slot 311, specifically located at the lower edge of the slot hole 313, protruding from the lower edge, that is, higher than the lower edge , which can prevent the anti-deformation nut 50 from falling off from the hole groove 311 . After the anti-deformation nut 50 is placed in the slot 313 , it cannot escape from the hole 311 by itself. Therefore, the anti-deformation nut 50 and the fixing frame 30 are integrated.

In this example, the anti-deformation nut can be a plastic part, which further reduces the production cost and simplifies the production process, and puts it into the slot from the slot opened on the outer side of the hole, increasing the flexibility of placing the anti-deformation nut, and After being put into the hole, it will not fall off, and it is integrated with the fixing frame, which makes the operation of installing the fixing frame to the installation box easier.

Embodiment four

In the fixing frame provided in this embodiment, the anti-deformation device is specifically a compression-resistant member, the fixing hole has a slot, and the lower end of the slot is provided with the compression-resistant member. The fixing frame is different from the fixing frame shown in FIGS. 3-6 in that: a compression-resistant piece is provided on the side of the lower end of the slot 311 of the fixing hole 31 . The compression member has a certain rigidity, and when the installation box 40 and the fixed frame 30 are installed together, the compression member is located between the upper end surface of the installation hole 41 of the installation box 40 and the lower end surface of the fixing hole 31, and the effect is when When the locking screw 20 passes through the fixing hole 31 and the mounting hole 41 to install the fixing frame 30 on the mounting box 40, an external force is applied to the locking screw 20 to compress the fixing frame 30 and the mounting box 40, and the pressure-resistant parts support The distance between the fixing frame 30 and the installation box 40 further prevents the deformation of the fixing frame 30 . The material of the anti-pressure part can be hard plastic or metal, etc., and the hardness is enough to support the pressure between the fixing part 30 and the installation box 40 when the locking screw is screwed in under the action of an external force, so that the fixing frame 30 has no deformation. or slight deformation.

Therefore, the maximum height of the compression member needs to be able to mount the fixing frame 30 on the installation box 40 by the locking screw 20, and the minimum value of the compression member is limited to prevent the large deformation of the fixing 30 during installation. The specific setting can be set according to the deformation target, generally more than 2 mm.

Referring to Fig. 7 for details, the compression member may specifically be a stacked wall. That is, the lower end side of the slot 311 is provided with a stacked wall 315 , and the stacked wall 315 has a porous structure. The porous structure of the stacked wall 315 is composed of a plurality of ribs 316 connected vertically and horizontally, and each column rib 316 can be cut with a common electrical tool such as a knife or diagonal pliers.

Further, the height of the overlapping wall 315 is equal to the height difference between the installation hole 41 of the installation box 40 and the lower end of the fixing hole 31 .

The overlapping wall 315 is disposed at the lower end of the outer edge of the inner diameter of the hole 311 , and the overlapping wall 315 has a curvature consistent with the installation position.

During installation, the main frame of the fixed frame is slightly deformed, and the lower end surface of the stacked wall of the fixed frame is in conflict with the upper end surface of the installation hole of the installation box. The locking screw cannot compress the stacked wall under the action of external force, so the main frame of the fixed frame is maintained produce large deformations.

Specifically, the compression member can also be a slender rod, that is, a slender rod is provided on one side of the lower end of the hole groove 311, and the length of the slender rod is equal to the distance between the mounting hole 41 of the mounting box 40 and the lower end of the fixing hole 31 of the fixed bracket 30. altitude difference. The elongated rod serves the same purpose as the stacked wall 315 .

In this embodiment, a pressure-resistant piece is provided at the lower end side of the slot of the fixing hole. After the fixing frame and the installation box are assembled, the pressure-resistant piece is located between the fixing frame and the installation box. After the end surface collides with the upper end surface of the mounting hole, because the compression member is rigid, it is supported between the fixing frame and the installation box, and the locking screw cannot continue to compress the compression member, which keeps the main frame of the fixing frame from further deformation.
