Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of distribution box installation support, in particular to a distribution box bracket. Background Art
[0002] A distribution box is a device that integrates electrical switching elements into a closed or semi-enclosed metal cabinet. As non-standard automation technology becomes increasingly mature, many companies' small equipment needs to be connected to a distribution box separately. The installation and fixing positions of the distribution box are random and changeable, and need to adapt to various complex environments. The existing distribution box bracket has a high manufacturing cost and the layout design is not well considered. For example, there are great safety hazards in terms of heat dissipation and fixing methods. For this reason, there is an urgent need for a distribution box bracket that can not only achieve effective heat dissipation, but also adapt to different installation requirements and has extremely low manufacturing costs.

[0021] 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 some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0022] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0023] like Figures 1 to 5 As shown, the utility model includes a flat support plate 1 and four groups of square tubes 2 installed at the bottom of the support plate 1. The front, rear, left and right sides of the upper end surface of the support plate 1 are provided with card slots 3. The front and rear card slots 3 are provided with card plates a301 that can move forward and backward along the card slot 3, and the left and right card slots 3 are provided with card plates b302 that can move left and right along the card slot 3. The card plates a301 and b302 are connected to the inner walls of their respective card slots 3 through springs 303. The function of the springs 303 is to pre-tighten the distribution box when it is placed on the support plate 1. At the same time, after the countersunk bolts 9 are locked, the springs still give an inward pulling force , so that even if the countersunk bolt 9 is loose, it will be firmly pressed against the distribution box; a rectangular bayonet 304 is provided in the middle position of the lower end surface of each slot 3 along the center direction of the support plate 1; the width of the front and rear slots 3 is greater than the width of the left and right slots 3, and each card plate a301 and card plate b302 are clearance-matched with the slots 3 in which they are located, and a countersunk hole that completely penetrates from top to bottom is provided at the center position of the upper end of each card plate a301 and card plate b302; a countersunk bolt 9 that can pass through the bayonet 304 is installed in the countersunk hole, and the countersunk bolt 9 is fixed by the gasket 901 and the nut at the bottom of the bayonet 304 to fix the specific position of each card plate.
[0024] Each group of square tubes 2 contains three and all are three-layer nested structures. The bottom square tube 2 is the outermost layer, and a shock absorber 6 is installed below it. The shock absorber 6 can provide buffering and shock absorption for the square tube 2 and the components above it in a complex working environment; a cylindrical counterweight block 7 is installed at the bottom of each shock absorber 6, the purpose of which is to increase the bottom weight, stabilize the device and give full play to the chassis structure of the shock absorber 6 at the bottom; a universal wheel 8 with a brake is arranged under each counterweight block 7 to ensure the fixation and movement of the device.
[0025] Each of the square tubes 2 is provided with arc rectangular notches of the same size, so that the three layers of nested square tubes 2 can be bolted through the height of the notched square tubes 2 using conventional bolts.
[0026] A plurality of rows of air ducts 4 are arranged on both sides of the slot 3. The air ducts 4 in different directions intersect and penetrate each other. The air ducts do not affect the support of the upper end surface of the support plate 1. At the same time, space is reserved at the bottom of the distribution box installed above. That is, the function of the air ducts 4 is to be more conducive to the heat dissipation of the distribution box above.
[0027] A stepped groove 5 is provided at the center of the support plate 1, and a magnet 501 is installed at the bottom of the stepped groove 5. The bottom of the stepped groove 5 is sealed by a 2 mm acrylic cover plate 502. The function of the magnet 501 is to magnetically attract the bottom of the distribution box above, and only for some distribution box shell materials that can be adsorbed.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
