Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-5, a low-voltage switch cabinet convenient to move includes a cabinet body 1, a bottom plate 5 and a bearing wheel 2; the bottom plate 5 is arranged at the lower end of the cabinet body 1, and the bearing wheels 2 are uniformly distributed on the lower bottom surface of the bottom plate 5 through the shock absorption seats 13; stepped grooves 6 are symmetrically formed in the lower surface of the bottom plate 5, mounting bearing seats 8 are fixedly arranged on the bottom plate 5 at two ends of each stepped groove 6, studs 9 are rotatably arranged on the mounting bearing seats 8, nuts 7 are symmetrically and threadedly connected to each stud 9, the nuts 7 are slidably connected with the bottom plate 5 through the stepped grooves 6, the lower end of each nut 7 is hinged to one end of a support rod 15, and the other ends of all the support rods 15 are hinged to the bearing plate 3; the same ends of the two double-end studs 9 are fixedly connected with third gears 12, wherein one third gear 12 is meshed with a second gear 11, the other third gear 12 is meshed with a first gear 10, and the first gear 10 is meshed with the second gear 11; the first gear 10 and the second gear 11 are both connected to the lower end of the bottom plate 5 through a connecting column 14, an adjusting hole 17 is formed in the center of the first gear 10, and the position of the adjusting hole 17 corresponds to the position of a conversion hole 4 formed in the lower end of the cabinet body 1; be provided with spring 16 in the shock attenuation seat 13, spring 16's effect is the shock attenuation, can select to use the spring 16 that the strength coefficient is great, and the installation cylinder and the spring 16 fixed connection of bearing wheel 2 top just cup joint with shock attenuation seat 13.
Wherein, the both sides screw thread of stud 9 are opposite to the direction of rotation, and are the triangle screw thread, and the triangle screw thread has the auto-lock nature, can ensure that bearing plate 3 is stable under any bearing state. The support bars 15 on the same stud bolt 9 are symmetrically distributed. When the bearing plate 3 is in a working state, the bearing plate is positioned below the lowest point of the bearing wheel 2; when the wheel is not in working state, the wheel is positioned on the upper side of the lowest point of the bearing wheel.
The support rod 15 on the same stud 9 is in a splayed shape when in a non-working state, the hinged parts of the support rod 15 and the bearing plate 3 are distributed far, so that the stability of the bearing plate 3 during supporting can be improved, and the inner diameter of the conversion hole 4 is larger than the inner diameter of the outer contour circumcircle of the adjusting hole 17.
When in use: the main principle part of the device is the conversion of a support part, and mainly comprises the steps of converting the support of a bearing wheel 2 into the support of a bearing plate 3 (after movement) and converting the support of the bearing plate 3 into the support of the bearing wheel 2 (before movement). Since the two processes are completely opposite, the working principle is briefly described by taking the example of the conversion from the support of the bearing wheel 2 to the support of the bearing plate 3:
firstly, the cabinet body 1 is pushed to a proper position through the bearing wheel 2, then an adjusting tool (here, an inner hexagonal wrench) is inserted into the adjusting hole 17, and then the adjusting hole 17 is driven to rotate, so that the first gear 10 is driven to rotate, the first gear 10 drives the second gear 11 and one of the third gears 12 to rotate, and the second gear 11 drives the other third gear 12 to rotate. Since the second gear 11 only serves as an idler gear to change the rotation direction at this position, the rotation direction and the rotation speed of the two third gears 12 are equal, so as to drive the two studs 9 to rotate in equal speed in equal direction. Because the nuts 7 are connected with the bottom plate 5 in a sliding manner and are in threaded connection with the stud bolts 9, when the stud bolts 9 rotate, the nuts 7 only do sliding movement relative to the bottom plate 5, and because the threads on the two sides of the stud bolts 9 are opposite in rotating direction, the two nuts 7 on the same stud bolt 9 only do opposite movement or movement in opposite directions (in the process, the two nuts 7 do opposite movement); because the two ends of the supporting rod 15 are respectively hinged with the nut 7 and the bearing plate 3, when the nut 7 on the same stud bolt 9 is far away from each other, the bearing plate 3 is pushed to the direction (i.e. supporting) far away from the stud bolt 9 by the supporting rod 15, the adjusting hole 17 is continuously rotated, the bearing plate 3 and the bottom plate 5 can be completely propped open, when the distance between the lower end surface of the supporting plate and the lower end surface of the bottom plate 5 is greater than the distance between the lowest point of the bearing wheel 2 and the lower end surface of the bottom plate 5, the supporting plate can reach a completely reliable and stable supporting state, at the moment, the bearing wheel 2 can not bear the gravity of the cabinet body 1 any more, at the moment, the adjusting hole 17 can be continuously rotated to adjust the.
The conversion process of this device is the whole conversion of whole bottom surface, and the in-process can not produce the vibration to can avoid the damage of components and parts, in addition, the adjustment structure in this device is located the inside of the cabinet body 1 completely, so can not influence the whole aesthetic measure of the cabinet body 1. The device has simple structure of parts, simple principle, low maintenance cost, stability and reliability in use, and simple rotation in the conversion process, so the operation is simple.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
