[0015] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] like Figure 1-Figure 2The switch connection bottom frame with anti-installation deformation function shown in the figure comprises a frame plate 1, the frame plate 1 is provided with a mounting hole to form a frame structure, a contact plate 2 extending downward is fixedly connected to the lower end surface of the inner wall of the mounting hole, the shape of the contact plate 2 fits the mounting hole, so that the functional part can pass through, and can be sleeved on the outer wall of the functional part, the inner wall of the mounting hole is provided with evenly distributed card grooves 6, and the card grooves 6 extend to the outer wall of the contact plate 2, the functional part has corresponding protrusions, and can be fixed to the frame plate 1 through the card grooves 6, the frame plate 1 The four corners are provided with fixing holes 4, through which the frame plate 1 can be fixed to the wall. The two sides of the frame plate 1 are fixedly connected with the clamping plates 3, and the connection relationship with the functional parts can be strengthened through the clamping plates 3. The outer wall edge of the frame plate 1 is fixedly connected with evenly distributed clamping blocks 5, and the clamping blocks 5 can be clamped into the corresponding grooves on the functional parts to further make the two fixed more tightly. The inner wall of the contact plate 2 is symmetrically provided with locking parts, which are used to penetrate the locking parts, and at the same time, the locking parts can prevent the locking parts from squeezing and deforming the frame plate 1. The locking parts include a clamping block 5 arranged at the outer wall of the frame plate 1. The limiting portion 8 on the inner wall of the contact plate 2 has an insertion hole 9 vertically penetrated in the middle of the limiting portion 8, and a convex point 10 is arranged on the top edge of the insertion hole 9 away from the frame plate 1. The convex point 10 is arranged at the top of the limiting portion 8 and is integrally formed, and the limiting portion 8 and the frame plate 1 form an inner concave surface. After the user inserts the locking member into the insertion hole 9, as the locking member goes deeper, the locking cover gradually approaches the frame plate 1, and the convex point 10 will replace the limiting portion 8 to contact the locking cover first, and when the locking cover continues to be squeezed, it will squeeze the convex point 10 and make the convex point 10 become The deformation of the convex point 10 offsets the pressure from the locking cover to a certain extent, and at the same time, the force is transmitted to the limiting portion 8, which will spread the pressure together with the frame plate 1 and the contact plate 2, and then reversely support the convex point 10. Through this design, the problem of frame plate deformation caused by direct contact between the locking cover and the frame plate 1 in the prior art is effectively solved, and because the frame plate 1 will not be deformed during locking, structural failure caused by frame plate deformation is avoided, so that the stability of the entire locking structure is greatly improved, and the locking effect is more reliable.

[0017] An indicator mark 7 is provided on the outer wall of the frame plate 1. By providing the indicator mark 7, it is convenient for the user to identify the front and back of the frame plate 1, thereby optimizing the installation steps.

[0018] The frame plate 1 is made of metal or plastic. The frame plate 1 can be made of metal or plastic, so that it has a wider range of applications.

[0019] Working principle:

[0020] After the user inserts the locking piece into the insertion hole 9, as the locking piece goes deeper, the locking cover gradually approaches the frame plate 1, and the protrusion 10 will replace the limiting portion 8 to preferentially contact the locking cover, and when the locking cover continues to be squeezed, the protrusion 10 will be squeezed and deformed. The deformation of the protrusion 10 offsets the pressure from the locking cover to a certain extent, and at the same time, the force is transmitted to the limiting portion 8, which will spread the pressure together with the frame plate 1 and the contact plate 2, and then support the protrusion 10 in the opposite direction. Through this design, the problem of frame plate deformation caused by direct contact between the locking cover and the frame plate 1 in the prior art is effectively solved, and because the frame plate 1 will not be deformed when locked, structural failure caused by frame plate deformation is avoided, the stability of the entire locking structure is greatly improved, and the locking effect is more reliable.
