DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1: Please refer to Figure 1-3 A relay with a protection function in this embodiment includes a relay body 1 and a protection box 2. A protection mechanism is arranged on the outside of the relay body 1. The protection box 2 is movably mounted on the outer surface of the relay body 1. A base 3 is fixedly mounted on the inner bottom wall of the protection box 2. The bottom of the base 3 is movably connected to the bottom of the relay body 1. A plurality of heat dissipation holes 4 are opened inside the protection box 2.

[0022] A box door is rotatably installed on the front side of the protection box 2 , which facilitates the maintenance of the relay body 1 , so that the relay body 1 can be maintained without taking it out of the protection box 2 .

[0023] There are two protective mechanisms, which are respectively located on the left and right sides of the relay body 1 , so as to achieve the purpose of fixing and protecting the relay body 1 from the left and right sides, thereby preventing the relay body 1 from loosening during use.

[0024] It should be noted that when the relay body 1 is in use, its internal structural connection methods are all existing technologies, and the relay body 1 is also an existing mature product, so it will not be described in detail in the present utility model.

[0025] Among them, a through groove is opened on the inner top wall of the protective box 2, the size of which is larger than the size of the relay body 1. Its function is to facilitate the removal of the relay body 1 from the protective box 2, so that the protective box 2 can protect relay bodies 1 of different sizes.

[0026] By adopting the above technical scheme, by setting up a protection mechanism, the relay body 1 can be protected, so that the relay body 1 is more stable during use and will not become loose due to long-term use. At the same time, the relay body 1 can also be protected and the service life of the relay body 1 will not be shortened. By setting up the heat dissipation holes 4, the purpose of heat dissipation of the relay body 1 is achieved, so that the relay body 1 will not be damaged due to excessive temperature during use, thereby improving the practicality of the relay with protection function.

[0027] Example 2: Please refer to Figure 1-2 On the basis of the first embodiment, the protection mechanism includes an electric telescopic rod 501 fixedly installed on the inner top wall of the protection box 2, a support plate 502 is fixedly installed on the bottom of the electric telescopic rod 501, and an extrusion disk 503 is rotatably installed on the front side of the support plate 502, a slide rod 504 is fixedly installed on the left side wall of the inner cavity of the protection box 2, a mounting plate 505 is slidably installed on the outer surface of the slide rod 504, a block 506 is fixedly installed on the right side of the mounting plate 505, a connecting column 507 is fixedly installed on the left side of the mounting plate 505, a fixed plate 508 is slidably connected to the outer surface of the slide rod 504, the right side of the fixed plate 508 is fixedly connected to the left side of the connecting column 507, a support rod 509 is fixedly installed on the left side of the fixed plate 508, a moving block 510 is fixedly installed on the left side of the support rod 509, and a spring 511 is movably installed on the outer surface of the slide rod 504, and the left and right sides of the spring 511 are respectively fixedly connected to the left side wall of the inner cavity of the protection box 2 and the left side of the fixed plate 508.

[0028] Among them, the moving block 510 is a right triangle when viewed from the front, and the outer surface of the extrusion plate 503 is pressed against the hypotenuse of the right triangle. The purpose is to enable the extrusion plate 503 to squeeze the moving block 510, so that the moving block 510 can move left and right, which is convenient for clamping and fixing the relay body 1.

[0029] In addition, when the clamping block 506 clamps and fixes the relay body 1 , the spring 511 is in a stretched state, so that the spring 511 can drive the fixing plate 508 to move to the left.

[0030] Among them, a controller is fixedly installed on the top of the protection box 2, and the two electric telescopic rods 501 are electrically connected to the controller, which enables the two electric telescopic rods 501 to work simultaneously.

[0031] It should be added that the electrical components appearing in the present invention are all electrically connected to an external main controller, and the main controller can be a conventional known device that controls a computer, etc. The circuits and controls involved in the present invention are all existing technologies and will not be elaborated on here.

[0032] Among them, there are card slots on the left and right sides of the relay body 1, and the size of the card slots is adapted to the size of the card block 506, which can fix the relay body 1 from the left and right sides, thereby making the relay body 1 more stable when in use and protecting the relay body 1.

[0033] By adopting the above technical scheme, the electric telescopic rod 501, the support plate 502, the extrusion plate 503, the slide rod 504, the mounting plate 505, the block 506, the connecting column 507, the fixing plate 508, the support rod 509, the moving block 510 and the spring 511 are used in coordination with each other, so that the relay body 1 can be fixed, and the relay body 1 can remain stable during use, thereby protecting the relay body 1 and improving the safety of the relay with protection function.

[0034] The working principle of the above embodiment is:

[0035] When the relay body 1 needs to be protected, the relay body 1 is first placed from the top of the protection box 2 into the inside thereof, so that the relay body 1 is placed above the base 3, and then the two electric telescopic rods 501 are started at the same time, so that the two electric telescopic rods 501 respectively drive the two support plates 502 to move downward at the same time, so that the two support plates 502 respectively drive the two extrusion plates 503 to move downward at the same time, and the two extrusion plates 503 respectively squeeze the two moving blocks 510 at the same time, so that the two moving blocks 510 move to the opposite side, and the two moving blocks 510 respectively drive the two fixed plates 508 and the two mounting plates 505 to move to the opposite side on the two sliding rods 504 at the same time, so that the two fixed plates 508 respectively stretch the two springs 511 at the same time, and then the two mounting plates 505 respectively drive the left and right sides of the card blocks 506 to move to the opposite side at the same time, so that the card blocks 506 are respectively connected with the card slots on the left and right sides of the relay body 1, so that the relay body 1 is fixed, so that the relay body 1 can be protected.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
