[0030] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0031] Please refer to Figures 1 to 8 The embodiment of the utility model provides a snap-fit ​​chassis mounting frame and a power regulator, including a base 4, two groups of hollow cylinders 9 are arranged on both sides of the base 4, and snap-fit ​​fixing components are slidably connected in the two groups of hollow cylinders 9.

[0032] The clamping and fixing assembly includes a positioning rod 10 slidably arranged in the hollow cylinder 9, one end of the positioning rod 10 is connected to a fixing head 12, and the fixing head 12 is similar to a wedge-shaped structure and can be clamped on the bottom block 2 at the lower end corner of the power regulator body 1.

[0033] In addition, a spring 11 is sleeved on the positioning rod 10 between the hollow cylinder 9 and the fixed head 12. The two ends of the spring 11 are respectively connected to the hollow cylinder 9 and the fixed head 12. When the power regulator body 1 is placed on the base 4, the spring 11 is squeezed by the fixed head 12. Therefore, when the fixed head 12 no longer squeezes the spring 11, the spring 11 prompts the fixed head 12 to engage with the bottom block 2, so that the engaging and fixing assembly slides outward when the power regulator body 1 enters the base 4, and the four corners of the power regulator body 1 are engaged and fixed when the power regulator body 1 is in contact with the base 4.

[0034] Furthermore, a long rod 13 is provided on one side of the fixed head 12, and the lower end of the long rod 13 is slidably connected to a slide groove 17 opened on the upper side of the base 4. At the same time, a spring 18 is provided in the slide groove 17, and one end of the spring 18 is connected to the protrusion 15 at the lower end of the long rod 13. When the fixed head 12 moves outward, the long rod 13 is prompted to stretch the spring 18, and after the spring 18 loses its strength, the spring 18 tightens the long rod 13 to improve the stability of the fixed head 12 and the bottom block 2.

[0035] Furthermore, rollers 14 are rotatably provided on both sides of the long rod 13 , and the two rollers 14 are respectively located on the base 4 on both sides of the slide slot 17 . When the long rod 13 moves, the rollers 14 roll on the base 4 , so that the long rod 13 moves stably.

[0036] In order to install the power regulator body 1, a threaded hole is opened at the other end of the positioning rod 10, and a screw 16 is threadedly connected in the threaded hole. A gasket is connected to one end of the screw 16. In the space with inner walls on both sides, the screw 16 can be rotated out so that the screw 16 and the gasket are pressed against the inner wall of the installation space, and the device can be installed.

[0037] It is worth mentioning that in order to meet the installation of the device in various scenarios, a rectangular rod 5 is arranged on the outside of the base 4, and the rectangular rod 5 can be divided into two L-shaped rod bodies. The L-shaped rod body is fixed to the outside of the base 4 through an ear plate. At the same time, the two L-shaped rod bodies are connected, and each L-shaped rod body is slidably provided with multiple fixing plates 6. The fixing plates 6 can slide on the L-shaped rod bodies and correspond to the mounting holes reserved in the installation space of the device. Each fixing plate 6 can be adjusted according to the position of the mounting hole. Bolt holes 7 are opened on the fixing plates 6. The bolt holes 7 have a first length, which can further correspond to the position of the mounting holes.

[0038] On the other hand, the present application also provides a power regulator of a snap-fit ​​chassis mounting frame, including a power regulator body 1, wherein bottom blocks 2 are provided at the four corners of the lower end of the power regulator body 1, and positioning holes 3 are provided on the lower side of the bottom block 2.

[0039] In order to improve the stability of the connection between the power regulator body 1 and the base 4 , at least four plug rods 8 are provided on the base 4 , and the plug rods 8 are plugged into and matched with the positioning holes 3 .

[0040] In summary, the working principle of a snap-fit ​​chassis mounting frame and a power regulator of an embodiment of the utility model is as follows: pull the positioning rod 10 outward, so that the positioning rod 10 compresses the spring 11, and the long rod 13 stretches the spring 2 18, so that the power regulator body 1 can be placed on the base 4, and the elastic action of the spring 11 and the spring 2 18 is used to fix the power regulator body 1 by snapping, and at the same time, the positioning hole 3 on the lower side of the bottom block 2 is plugged into the insertion rod 8. During installation, the installation method is selected according to the scene, and the screw rod 16 can be rotated so that the screw rod 16 with the gasket fits with the inner wall of the space where the power regulator body 1 needs to be installed, and the power regulator body 1 can be quickly installed. Secondly, the fixing plate 6 is slid on the rectangular rod 5, so that any fixing plate 6 can correspond to the installation hole reserved at the location where the power regulator body 1 needs to be installed.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
