[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] As Figures 1-5 shown, the utility model discloses a pressure power switch, including the upper shell 1 and lower shell 2 of fixed connection together through bolt mode, be provided with pressure chamber 3 between the upper shell 1 and lower shell 2, be provided with pressure relief assembly 11 and pressure source inlet 12 on the upper shell 1, the left and right sides of lower shell 2 are all installed with mounting side ear 21, still include the hinge 4 between each mounting side ear 21 and lower shell 2, each mounting side ear 21 all is provided with mounting hole 231 and each mounting side ear 21 all is through corresponding hinge 4 and lower shell 2 rotation connection, because each mounting side ear 21 all is through corresponding hinge 4 and lower shell 2 rotation connection, thus when needing to store and deposit pressure power switch, at this time, rotate each mounting side ear 21 towards back and then can make it towards the rear end surface of lower shell 2 close and then make the space that pressure power switch whole is located in horizontal direction reduces and then provides the convenience for depositing in the place of small horizontal space.

[0028] The pressure relief assembly 11 comprises a pressure relief sleeve 111 fixed to the upper shell 1 by welding or the like and in communication with the pressure cavity 3, a guide rod 112 slidingly installed in the pressure relief sleeve 111, and a spring 113 sleeved around the guide rod 112. The pressure relief sleeve 111 is provided with a pressure relief hole 1111. The guide rod 112 is fixedly installed below the pressure relief hole 1111 and provided with a sealing ring 1121. One end of the spring 113 is fixedly connected with the sealing ring 1121 by welding or the like, and the other end is fixedly connected with the pressure relief sleeve 111 by welding or the like. Therefore, when the pressure in the pressure cavity 3 is too large, the sealing ring 1121 will be subjected to an upward force, thereby driving the guide rod 112 to move upward relative to the pressure relief sleeve 111, and compressing the spring 113 so that the pressure can be relieved through the pressure relief hole 1111. When the pressure in the pressure cavity 3 is reduced, the elastic force of the spring 113 drives the sealing ring 1121 and the guide rod 112 to move downward, thereby preventing the pressure in the pressure cavity 3 from being relieved through the pressure relief hole 1111.

[0029] Each of the mounting side ears 21 is provided with a first magnet 211, and the lower shell 2 is provided with a second magnet 22 on the rotation track of each of the mounting side ears 21 and is attracted to the first magnet 211. Therefore, when the pressure power switch is stored, each of the mounting side ears 21 is rotated backward, and the first magnet 211 on each of the mounting side ears 21 is attracted to the second magnet 22 on the lower shell 2 during the approach of each of the mounting side ears 21 to the lower shell 2, thereby enabling each of the mounting side ears 21 to be stably positioned at the rear side of the lower shell 2 and facilitating the storage of the pressure power switch.

[0030] Preferably, each of the mounting side ears 21 is detachably installed with a mounting panel 23 by bolts or the like. Each of the mounting panels 23 is provided with a mounting hole 231. Different diameters of the mounting hole 231 can be produced during production. Since each of the mounting panels 23 is detachably connected with the corresponding mounting side ear 21, the mounting panel 23 can be adjusted according to the fasteners such as bolts before the pressure power switch is assembled with an object to which the pressure power switch is to be installed. The mounting panel 23 with a mounting hole 231 of a suitable diameter is installed on the corresponding mounting side ear 21, thereby facilitating the assembly of the two-dimensional pressure power switch.

[0031] The lower shell 2 is provided with positioning columns 13 protruding forward at each top corner, the upper shell 1 is fixedly provided with mounting seats 24 corresponding to the positioning columns 13, and each mounting seat 24 is provided with a positioning groove 241 for inserting the corresponding positioning column 13. Since the positioning columns 13 at each top corner of the lower shell 2 are inserted into the corresponding mounting seat 24 of the upper shell 1, the relative position of the upper shell 1 and the lower shell 2 can be determined before they are fixedly connected. Therefore, the positioning columns 13 and the positioning seats can facilitate the preliminary positioning of the upper shell 1 and the lower shell 2.

[0032] The number of limiting rings 5 is the same as that of the positioning columns 13. Each limiting ring 5 is detachably connected to the corresponding positioning column 13 by buckling or the like, and the front end surface of each limiting ring 5 abuts against the lower shell 2. Since each limiting ring 5 is detachably connected to the corresponding positioning column 13 and abuts against the lower shell 2, after the relative position of the upper shell 1 and the lower shell 2 is determined, each limiting ring 5 is detachably mounted on the corresponding positioning column 13. Under the limitation of each limiting ring 5, each positioning column 13 cannot move in the front-back direction relative to the upper shell 1, so that the upper shell 1 and the lower shell 2 can be stably connected together.

[0033] Each positioning column 13 is circumferentially spaced apart by a plurality of limiting insertion blocks 131. Each limiting ring 5 is made of a material that is easy to deform, such as rubber, and is provided with a limiting insertion groove 51 corresponding to each limiting insertion block 131. Since each limiting insertion block 131 is present on the positioning column 13, after each positioning column 13 is inserted into the corresponding mounting seat 24, the limiting ring 5 needs to be bent to deform and be forcibly pulled to enable the limiting insertion block 131 on the positioning column 13 to be inserted into the limiting insertion groove 51 of the limiting ring 5. At this time, since the limiting ring 5 abuts against the lower shell 2, each positioning column 13 cannot move forward or backward. Since each limiting insertion block 131 is present, the limiting ring 5 cannot rotate relative to the positioning column 13, so that the limiting ring 5 can be stably mounted on the positioning column 13 without external force. When it is necessary to detach the limiting ring 5 from the positioning column 13, the limiting ring 5 is deformed by applying force to it, so that the limiting insertion block 131 can be separated from the corresponding limiting insertion groove 51, and the limiting ring 5 can be removed from the corresponding positioning column 13.

[0034] Preferably, each limiting insertion block 131 is provided in a stepped shape with the outside being narrower than the inside. Since the outermost side of each limiting insertion block 131 is the narrowest and is first inserted into the limiting insertion groove 51 during the bending of the limiting ring 5, each limiting insertion block 131 provided in a stepped shape with the outside being narrower than the inside can be more smoothly inserted into the limiting insertion groove 51 of the limiting ring 5.

[0035] In addition, the upper shell 1 is provided with a matching ring 14 protruding rearward, and the lower shell 2 is provided with a matching groove 25 corresponding to the matching ring 14. After the positioning columns 13 of the lower shell 2 are installed into the mounting seats 24 of the upper shell 1, the matching ring 14 on the upper shell 1 is inserted into the matching groove 25 of the lower shell 2. Therefore, after the assembly of the upper shell 1 and the lower shell 2 is completed, if dust from the outside enters between the upper shell 1 and the lower shell 2, the dust will first be blocked by the matching ring 14 and thus it is difficult to enter the pressure cavity 3.

[0036] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
