[0025] Embodiment 1: A high-pressure blower that is easy to install. The high-pressure blower that is easy to install includes: a mounting block 1.

[0026] Specifically, a plurality of symmetrically arranged fixing bolts 2 are slidably inserted into the side of the mounting block 1, and a Roots blower body 3 and a nut 4 are arranged on one end of the fixing bolt 2 in sequence from bottom to top, the Roots blower body 3 and the fixing bolt 2 are sleeved, and the nut 4 and the fixing bolt 2 are threadedly sleeved, and a plurality of limit blocks 5 arranged in a "V" shape and corresponding to the position of the nut 4 are slidably connected to the side of the mounting block 1, and a spring 6 is fixedly connected between the limit block 5 and the mounting block 1. In actual implementation, after the limit block 5 is restrained, the Roots blower body 3 is first placed on the mounting block 1, and then the fixing The bolt 2, the mounting block 1 and the Roots blower body 3 are slidably plugged in, and the nut 4 is threadedly sleeved on the fixing bolt 2, so as to fix the Roots blower body 3 on the mounting block 1. At this time, when the restraint on the limit block 5 is released, the limit block 5 will push the limit block 5 to slide and contact the nut 4 under the action of the spring 6. Because the limit block 5 is set in a "V" shape, it can limit the nut 4 from rotating left and right, thereby ensuring that the vibration generated during the operation of the Roots blower will not affect the installation of the fixing bolt 2 and the nut 4, so that the Roots blower body 3 is in a stable state when installed on the mounting block 1.

[0027] In order to facilitate the installation of the limit block 5, the side of the mounting block 1 of the present application is fixedly connected with two symmetrically arranged mounting plates 9, and one side of the mounting plate 9 is slidably plugged with a fixing rod 51 arranged in a "polygonal shape". The fixing rod 51 is fixedly connected to the limit block 5 and slidably plugged with the spring 6. The mounting plate 9 can give the limit block 5 an installation height, and the "polygonal" fixing rod 51 can prevent the limit block 5 from rotating.

[0028] In order to further ensure the installation stability of the nut 4, the upper end of the limit block 5 of the present application is rotatably connected to a plurality of screw rods 7, and the side threads of the screw rods 7 are inserted with an inclined pressure rod 8. After the limit block 5 slides into place, the screw rod 7 is rotated to drive the pressure rod 8 to slide down, so that the pressure rod 8 contacts the nut 4 and forms a blockage for the nut 4, thereby further limiting the nut 4 from sliding away from the fixing bolt 2.

[0029] In order to facilitate the installation of the screw rod 7 and the pressure rod 8, the upper end of the limit block 5 of the present application is fixedly connected with a plurality of connecting blocks 52, the screw rod 7 and the connecting block 52 are rotatably connected, and one side of the pressure rod 8 is fixedly connected with a slider 81, the slider 81 is threadedly sleeved with the screw rod 7 and is slidably connected with the connecting block 52, when the pressure rod 8 rotates, it will drive the slider 81 to slide, and the sliding of the slider 81 will drive the pressure rod 8 to slide, and under the restriction of the connecting block 52, the sliding trajectory of the pressure rod 8 can be fixed, so that the pressure rod 8 can better resist the nut 4.

[0030] In order to facilitate the restraint of the limit block 5, the upper end of the limit block 5 of the present application is fixedly connected with a protruding plate 53, and a threaded hole 54 is penetrated through the side of the protruding plate 53. The side of the mounting plate 9 is rotatably connected with a threaded rod 92 corresponding to the position of the threaded hole 54. When it is necessary to restrain the limit block 5, the limit block 5 is pushed to slide toward the end of the mounting plate 9, and then the threaded rod 92 is allowed to contact with the protruding plate 53. Then, the threaded rod 92 is rotated to allow the threaded rod 92 and the threaded hole 54 to be threadedly inserted, thereby fixing the protruding plate 53 on the threaded rod 92, and then fixing the limit block 5 at a position away from the fixing bolt 2.

[0031] In order to facilitate the installation of the fixed rod 51 and the threaded rod 92, the side of the mounting plate 9 of the present application is provided with a plurality of positioning grooves 91 for sliding and inserting the fixed rod 51 and a plurality of mounting grooves 94 for rotatably installing the threaded rod 92. The side of the threaded rod 92 is fixedly connected with a positioning block 93, and the positioning block 93 and the mounting groove 94 are rotatably connected. The positioning groove 91 can allow the fixed rod 51 to be slidably inserted into the mounting plate 9. Through the cooperation of the positioning block 93 and the mounting groove 94, it can be ensured that the threaded rod 92 will not be displaced when it is rotatably installed on the mounting plate 9.

[0032] Although 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.
