[0005] To address the shortcomings of existing technologies, this invention provides an easy-to-install control cabinet for electromechanical engineering, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a control cabinet for electromechanical engineering that is easy to install, including a base, a groove on the top of the base, a sliding groove inside the groove, a main body on the top of the groove, an installation device on the base, a stop device on the base, and a protective device on the base;

[0007] The installation device includes a rotating wheel, a threaded rod, a long plate, a round rod, a pressing plate, a telescopic block, a return spring, a handle, a spring sheet, and a limiting rod. The threaded rod is rotatably mounted on the front of the base. The rotating wheel is fixedly mounted on one end of the threaded rod. The long plate is slidably mounted inside a groove. The other end of the threaded rod is rotatably mounted on the front of the long plate. The handle is fixedly mounted on the front of the rotating wheel. The limiting rod is slidably mounted on the front of the long plate. A slot is formed on the circumference of the threaded rod. The round rod slides through the long plate. The pressing plate is fixedly mounted on the side of the round rod away from the main body. A movable groove is formed on the circumference of the round rod. The telescopic block is disposed inside the movable groove. The spring sheet is fixedly mounted between the telescopic block and the round rod. The return spring is fixedly mounted between the long plate and the pressing plate. By setting up the installation device, the main body can be quickly installed, while preventing excessive force from being applied to the main body and causing damage to the surface of the main body.

[0008] According to the above technical solution, the limiting rod is in contact with the threaded rod, and both ends of the limiting rod are set as inclined surfaces. The limiting rod limits the threaded rod by moving the telescopic block.

[0009] According to the above technical solution, the side of the telescopic block closest to the long plate is set as an inclined surface, and the inclined surface of the telescopic block contacts the long plate. By setting one side of the telescopic block as an inclined surface, the round rod can be reset when disassembling the main body.

[0010] According to the above technical solution, the stopping device includes a protective plate, a connecting rod, an inclined plate, a connecting plate, a stopping rod, a roller, a second return spring, and a third return spring. One end of the connecting rod is disposed inside the base, the protective plate is fixedly installed at the other end of the connecting rod, the inclined plate is fixedly installed on the side of the protective plate near the base, the second return spring is fixedly installed between the protective plate and the base, the roller is rotatably installed at the bottom of the base, the connecting plate is disposed inside the base, the third return spring is fixedly installed between the connecting plate and the base, and the stopping rod is fixedly installed at the bottom of the connecting plate. By setting the stopping device, it can effectively prevent the main body from being impacted when moving, and avoid the invention from moving after an impact, thereby causing the internal equipment of the main body to move.

[0011] According to the above technical solution, the bottom of the base is provided with multiple rollers and multiple stop rods. The stop rods are in contact with the rollers. By setting the stop rods, the rollers can be restricted after the invention is impacted, so as to prevent movement after impact.

[0012] According to the above technical solution, the side of the inclined panel near the connecting plate is set as an inclined surface, and the second reset spring is fixedly installed between the bottom of the connecting plate and the base. The reset of the connecting plate is achieved by setting the elastic force of the second reset spring.

[0013] According to the above technical solution, the protective device includes a baffle, a rotating shaft, a gear, a rack, a slider, a sleeve, a short rod, and a return spring. The sleeve is fixedly installed on the top of the base, the slider is slidably installed inside the sleeve, the return spring is fixedly installed between the slider and the sleeve, the short rod is fixedly installed on the top of the slider, a positioning groove is provided on the top of the base, the rack is fixedly installed on the top of the connecting plate, the rotating shaft is rotatably installed inside the positioning groove, the gear is fixedly installed on the circumferential surface of the rotating shaft, a sliding groove is provided on the top of the base, and the baffle is disposed inside the sliding groove. By setting up the protective device, the main body is prevented from opening after being impacted, thereby preventing the internal equipment from falling and causing damage.

[0014] According to the above technical solution, a limiting groove is provided on the side of the rack near the slider, and the side of the slider near the rack is set as an inclined surface. The slider contacts the limiting groove, and the baffle is fixedly installed with teeth on the side near the gear. The gear meshes with the teeth and the rack. By setting the slider to enter the limiting groove, the rack is limited. After being impacted, the baffle directly and slowly descends, thus failing to protect the main body.

[0015] This invention provides a control cabinet for electromechanical engineering that is easy to install. It has the following advantages:

[0016] (1) In this invention, the main body is placed at the mounting position of the base, the handle is held and the rotating wheel is rotated, the rotating wheel drives the threaded rod to rotate, the rotating threaded rod drives the long plate to move, the long plate drives the round rod to move, the round rod drives the pressing plate to move, the pressing plate moves and contacts the main body, the main body is installed by the pressing plate, the pressing plate continues to move so that the long plate moves relative to the pressing plate, so that the round rod moves relative to the long plate, so that the telescopic block is exposed, the telescopic block moves under the influence of the elastic force of the spring, the telescopic block moves and contacts the limiting rod, the telescopic block continues to move and drives the limiting rod to move, the limiting rod moves and is inserted into the groove of the circumferential surface of the threaded rod, the limiting rod limits the threaded rod, and avoids applying too much force to the main body during installation, so as to cause the surface of the main body to be deformed by force, which may cause damage to the internal equipment of the main body.

[0017] (2) When the invention is moving and hits other objects, the protective plate is impacted and moves. The movement of the protective plate causes the connecting rod to move. The movement of the connecting rod causes the inclined plate to move. The movement of the inclined plate causes the inclined surface of the inclined plate to contact the connecting plate. The inclined plate continues to move and causes the connecting plate to move downward. The downward movement of the connecting plate causes the stop rod to move. The stop rod moves and contacts the roller, restricting the roller so that the roller cannot rotate. Thus, when the base is impacted, the roller is jammed to avoid causing a more serious accident.

[0018] (3) In this invention, the connecting plate descends, causing the rack to descend, which in turn causes the gear to rotate. The rotation of the gear causes the baffle to rise, thus preventing the main body from opening after being impacted and preventing internal force movement that could cause internal malfunctions. At the same time, the rack descends, causing the inclined surface of the slider to contact the limiting groove. The rack continues to descend, causing the slider to move. When the slider moves to a point where it no longer contacts the limiting groove, it is affected by the elastic force of the No. 3 spring and moves into the limiting groove, limiting the rack. This prevents the limiting of the roller from being released directly after the impact, which could cause the invention to move in the opposite direction and cause another collision. When it is necessary to release the limiting of the rack by the slider, the short rod is pulled. The short rod moves under force, causing the slider to move. The slider moves and contacts the limiting of the rack, releasing the limiting rack. The invention can be moved to a safe position by the manual release of the limiting by the staff.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-7 One embodiment of the present invention is: a control cabinet for electromechanical engineering that is easy to install, including a base 1, a groove is provided on the top of the base 1, a sliding groove is provided inside the groove, a main body 2 is provided on the top of the groove, and an installation device is provided on the base 1.

[0029] The mounting device includes a rotating wheel 301, a threaded rod 302, a long plate 303, a round rod 304, a pressing plate 305, a telescopic block 306, a return spring 307, a handle 308, a spring piece 309, and a limiting rod 310. The threaded rod 302 is rotatably mounted on the front of the base 1. The rotating wheel 301 is fixedly mounted on one end of the threaded rod 302. The long plate 303 is slidably mounted inside the groove. The other end of the threaded rod 302 is rotatably mounted on the front of the long plate 303. The handle 308 is fixedly mounted on the front of the rotating wheel 301. The limiting rod 310 is slidably mounted on the front of the long plate 303. A slot is provided on the circumferential surface of rod 302. The round rod 304 slides through the long plate 303. The pressing plate 305 is fixedly installed on the side of the round rod 304 away from the main body 2. A movable groove is provided on the circumferential surface of the round rod 304. The telescopic block 306 is set inside the movable groove. The spring piece 309 is fixedly installed between the telescopic block 306 and the round rod 304. The return spring 307 is fixedly installed between the long plate 303 and the pressing plate 305. The main body 2 can be quickly installed by setting the installation device, while preventing excessive force from being applied to the main body 2 and causing damage to the surface of the main body 2.

[0030] The limiting rod 310 contacts the threaded rod 302. Both ends of the limiting rod 310 are set as inclined surfaces. The limiting rod 310 limits the threaded rod 302 by moving the telescopic block 306.

[0031] The side of the telescopic block 306 closest to the long plate 303 is set as an inclined surface. The inclined surface of the telescopic block 306 contacts the long plate 303. By setting one side of the telescopic block 306 as an inclined surface, the round rod 304 can be reset when the main body 2 is disassembled.

[0032] In this embodiment, during operation: the main body 2 is placed at the mounting position of the base 1, and the handle 308 is held to rotate the rotating wheel 301. The rotation of the rotating wheel 301 drives the threaded rod 302 to rotate, which in turn drives the long plate 303 to move. The movement of the long plate 303 drives the round rod 304 to move, which in turn drives the pressing plate 305 to move. The pressing plate 305 moves and comes into contact with the main body 2. The pressing plate 305 continues to move, causing the long plate 303 to move relative to the pressing plate 305, which in turn causes the round rod 304 to move relative to the long plate 303, thus exposing the telescopic block 306. The telescopic block 306 moves under the influence of the elastic force of the spring piece 309. The telescopic block 306 moves and comes into contact with the limiting rod 310. The telescopic block 306 continues to move, driving the limiting rod 310 to move. The limiting rod 310 moves and engages in the groove on the circumferential surface of the threaded rod 302, thus limiting the threaded rod 302.

[0033] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the base 1 is provided with a stop device, which includes a protective plate 401, a connecting rod 402, an inclined plate 403, a connecting plate 404, a stop rod 405, a roller 406, a second return spring 407, and a third return spring 408. One end of the connecting rod 402 is disposed inside the base 1, the protective plate 401 is fixedly installed at the other end of the connecting rod 402, the inclined plate 403 is fixedly installed on the side of the protective plate 401 near the base 1, the second return spring 407 is fixedly installed between the protective plate 401 and the base 1, the roller 406 is rotatably installed at the bottom of the base 1, the connecting plate 404 is disposed inside the base 1, the third return spring 408 is fixedly installed between the connecting plate 404 and the base 1, and the stop rod 405 is fixedly installed at the bottom of the connecting plate 404. By providing the stop device, it is possible to effectively prevent the main body 2 from being impacted when moving, and to avoid the invention from moving after an impact, thereby causing the internal equipment of the main body 2 to move.

[0034] The base 1 has multiple rollers 406 at its bottom and multiple stop rods 405. The stop rods 405 contact the rollers 406. By setting the stop rods 405, the rollers 406 can be restricted after the invention is impacted, so as to prevent them from moving after being impacted.

[0035] The inclined plate 403 is set as an inclined surface on the side near the connecting plate 404. The second reset spring 407 is fixedly installed between the bottom of the connecting plate 404 and the base 1. The reset of the connecting plate 404 is achieved by setting the elastic force of the second reset spring 407.

[0036] The base 1 is equipped with a protective device, which includes a baffle 501, a rotating shaft 502, a gear 503, a rack 504, a slider 505, a housing 506, a short rod 507, and a return spring 508. The housing 506 is fixedly installed on the top of the base 1, the slider 505 is slidably installed inside the housing 506, the return spring 508 is fixedly installed between the slider 505 and the housing 506, and the short rod 507 is fixedly installed on the top of the slider 505. A positioning groove is provided on the top of the base 1, the rack 504 is fixedly installed on the top of the connecting plate 404, the rotating shaft 502 is rotatably installed inside the positioning groove, the gear 503 is fixedly installed on the circumferential surface of the rotating shaft 502, and a sliding groove is provided on the top of the base 1. The baffle 501 is located inside the sliding groove. By setting up the protective device, the main body 2 is prevented from opening after being impacted, thereby preventing the internal equipment from falling and causing damage.

[0037] A limiting groove is provided on the side of the rack 504 near the slider 505. The side of the slider 505 near the rack 504 is set as an inclined surface. The slider 505 contacts the limiting groove. The baffle 501 is fixedly installed with teeth on the side near the gear 503. The gear 503 meshes with the teeth and the rack 504. The rack 504 is limited by setting the slider 505 to enter the limiting groove. After being impacted, the baffle 501 descends slowly and directly, thus failing to protect the main body 2.

[0038] In this embodiment, when the invention is moved and collides with other objects, the protective plate 401 is impacted and moves. The movement of the protective plate 401 causes the connecting rod 402 to move, and at the same time, the movement of the protective plate 401 causes the inclined plate 403 to move. The movement of the inclined plate 403 causes the inclined surface of the inclined plate 403 to contact the connecting plate 404. The inclined plate 403 continues to move, causing the connecting plate 404 to move downward. The downward movement of the connecting plate 404 causes the stop rod 405 to move. The stop rod 405 moves and contacts the roller 406, restricting the roller 406 and preventing it from rotating.

[0039] Simultaneously, when the base 1 is impacted, the connecting plate 404 descends, causing the rack 504 to descend as well. The descent of the rack 504 causes the gear 503 to rotate, which in turn causes the baffle 501 to rise. At the same time, the descent of the rack 504 causes the inclined surface of the slider 505 to contact the limiting groove. As the rack 504 continues to descend, the slider 505 moves. When the slider 505 moves to a point where it is no longer in contact with the limiting groove, it is moved by the elastic force of the return spring 508, entering the limiting groove and limiting the rack 504. When it is necessary to release the slider 505... When the rack 504 is limited, the short rod 507 is pulled. The short rod 507 moves under force, which drives the slider 505 to move. The slider 505 moves and releases the limitation on the rack 504. The release of the limitation on the rack 504 allows the connecting plate 404 to move under the influence of the elastic force of the return spring 408. The movement of the connecting plate 404 drives the stop rod 405 to reset. The reset of the stop rod 405 releases the limitation on the roller 406, allowing the roller 406 to continue to rotate. The staff moves the invention to a safe position and inspects the internal equipment of the main body 2.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
