[0003] In the prior art, there is a utility model patent with the publication (announcement) number CN218732736U, entitled a low-voltage withdrawable switch cabinet, which includes a cabinet shell; a heat dissipation mechanism, including a mounting ring arranged inside the cabinet shell, a ventilation port provided on one side surface of the cabinet shell, the mounting ring connected to the ventilation port, a plurality of support plates fixedly connected inside the mounting ring, a fixing ring provided on one side of the plurality of support plates, the fixing ring fixedly connected to the support plate, a rotating shaft provided inside the fixing ring, the fixing ring rotates in cooperation with the rotating shaft, and a plurality of blades are provided outside the rotating shaft; the utility model starts a driving motor to drive the rotating shaft to rotate, thereby rotating the blades, sucking in the outside air, filtering the impurities through the dustproof net, and then entering the cabinet shell, and then ventilating the air inside the placement box through the heat dissipation port, and using the heat exchange principle to take away the heat, thereby achieving the purpose of heat dissipation of the placement box.

[0004] The device of this patent can dissipate heat for each layer of drawer boxes in a timely manner. However, when the device of this patent pulls out the drawer boxes in the switch cabinet, due to the large number of electronic components inside the drawer boxes and their heavy weight, it is very easy to pull out all the drawer boxes when pulling them out, which can easily cause the drawer boxes to fall and cause damage to the electronic components. Utility Model Content

[0005] The purpose of the utility model is to provide a drawable stability switch cabinet.

[0006] The technical problem solved by the present invention is that when the existing equipment pulls out the drawer box in the switch cabinet, due to the large number of electronic components inside the drawer box and the heavy weight, it is very easy to pull out the entire drawer box when pulling it out, which can easily cause the drawer box to fall.

[0007] The utility model can be implemented through the following technical solutions: a withdrawable stability switch cabinet, comprising a plurality of mounting partitions fixed in the cabinet cavity, a drawer box being provided on each mounting partition, positioning wheels being rotatably connected to both sides of the bottom wall of the drawer box, and a sliding groove for sliding the positioning wheels being provided in the inner cavity of the mounting partition;

[0008] The inner cavity of the mounting partition is provided with a limiting mechanism for limiting the different sliding positions of the positioning wheel. The limiting mechanism includes a transmission plate symmetrically slidably connected to the inner cavity of the mounting partition and corresponding one-to-one to the positioning wheel. One side of the transmission plate is equidistantly and horizontally elastically slidably connected with multiple limiting blocks. One side of the positioning wheel is provided with a slot that cooperates with the limiting block. The setting of multiple limiting blocks facilitates limiting the different sliding positions of the positioning wheel.

[0009] The further technical improvement of the present invention is that the inner cavity of the mounting partition is provided with a driving assembly that enables the two transmission plates to move relative to each other. The driving assembly includes a bidirectional screw that is rotatably connected to the inner cavity of the mounting partition. The two sections of the external thread of the bidirectional screw with opposite thread rotation directions are both threaded with a screw sleeve fixedly connected to the transmission plate. The screw sleeve is slidably connected to the inner cavity of the mounting partition. Rotating the bidirectional screw causes the two screw sleeves to move relative to each other in the inner cavity of the mounting partition.

[0010] A further technical improvement of the present invention is that one end of the bidirectional screw passes through the installation partition and the cabinet body in sequence and extends to the outside of the cabinet body, and a handle is fixedly installed on the end of the bidirectional screw extending to the outside of the cabinet body, and the outer peripheral wall of the handle is engraved with anti-slip grooves. The setting of the anti-slip grooves facilitates the staff to better rotate the handle.

[0011] A further technical improvement of the present invention is that the handle and the cabinet body are fixed by a positioning pin, and the positioning pin is provided to facilitate the position limiting of the handle, thereby preventing the handle from being reversed due to external reasons.

[0012] A further technical improvement of the present invention is that the top wall on which the partition is installed is symmetrically rotatably connected to a plurality of rollers that abut against the bottom wall of the drawer box. The rollers can be rotated by pushing the drawer box, thereby saving the staff's effort and accelerating the installation speed of the drawer box.

[0013] A further technical improvement of the present invention is that: both inner side walls of the cabinet are fixedly installed with a protrusion group, and both sides of the drawer box are provided with an inner groove that cooperates with the protrusion group. The coordinated arrangement of the protrusion group and the inner groove facilitates the stability of the drawer box when sliding and reduces the chance of the drawer box falling.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] When the drawer box needs to be pulled out of the cabinet body, the limit of the drawer box is first released. When the limit is released, the positioning pin in the rotary handle is first taken out, and then the rotary handle is turned to rotate the bidirectional screw. Since the threads on the outer surface of the bidirectional screw are two sections with opposite rotation directions, the two screw sleeves on the bidirectional screw are moved in opposite directions through the thread transmission action. The movement of the two screw sleeves can make the limit block disengage from the corresponding slot in the positioning wheel through the transmission plate. At this time, the drawer box is pulled again. After being pulled to a certain distance, the transmission plate can be reset by rotating the rotary handle in the opposite direction, and the limit block can be put into the corresponding slot in the positioning wheel again by the elastic force of the extrusion spring, thereby facilitating the limiting of different sliding positions of the drawer box, thereby reducing the probability of the drawer box falling and improving the stability of the drawer box being pulled out, thereby facilitating meeting the use needs of the staff.

[0016] 2. When the utility model is in use, the inner grooves on both sides of the drawer box correspond one to one with the protrusions in the inner cavity of the cabinet. At this time, the bottom grooves of the bottom wall of the drawer box will abut against the multiple rollers rotatably connected in the mounting partition. The rollers can be rotated by pushing the drawer box, and the rotation of the rollers facilitates the drawing and pulling of the drawer box, thereby saving the staff's effort and facilitating use.

[0028] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0029] See also Figure 1-5 As shown, this embodiment provides a technical solution, a withdrawable stability switch cabinet, including a cabinet body 1, a mounting partition 4 with multiple drawer boxes 2 fixedly installed vertically and equidistantly between the two inner side walls of the cabinet body 1, the drawer boxes 2 are arranged on the mounting partition 4, and the bottom wall of the drawer boxes 2 is penetrated by a plurality of evenly distributed mounting through holes 3, which are used to facilitate workers to install electronic components;

[0030] Both inner side walls of the cabinet body 1 are fixedly mounted with protrusion groups 11, and both sides of the drawer box 2 are provided with inner grooves 12 that match the protrusion groups 11;

[0031] Two rolling grooves 41 are symmetrically provided on the top wall of the mounting partition 4, and a plurality of rotating shafts 42 are equidistantly connected to each other between the two inner side walls of the rolling groove 41 through bearings. The outer peripheral wall of the rotating shaft 42 is fixedly sleeved with a roller 43, and the bottom wall of the drawer box 2 is provided with a bottom groove 44 that abuts against the outer peripheral wall of the roller 43. Pushing the drawer box 2 causes the roller 43 to rotate, which is conducive to quickly installing the drawer box 2 in the cabinet 1. The two inner side walls of the bottom groove 44 are rotatably connected with a rotating shaft 45, and the outer peripheral wall of the rotating shaft 45 is fixedly sleeved with a positioning wheel 46. The inner cavity of the mounting partition 4 is provided with a sliding groove 47 for the positioning wheel 46 to slide.

[0032] The inner cavity of each mounting partition 4 is provided with a limiting mechanism for limiting the positioning wheel 46. The limiting mechanism includes an inner groove 48 opened in the inner cavity of the mounting partition 4, and a bidirectional screw 49 is rotatably connected between the two inner side walls of the inner groove 48 through a bearing. One side of the bidirectional screw 49 near the end is provided with two sections of external threads with opposite thread rotation directions. The two sections of external threads of the bidirectional screw 49 with opposite thread rotation directions are threadedly sleeved with a screw sleeve 410 that is slidably connected to the inner cavity of the inner groove 48. The top wall of the screw sleeve 410 is fixedly mounted with a transmission plate 411 that is slidably connected to the inner cavity of the inner groove 48. A plurality of rectangular grooves 412 are equidistantly opened on the side of the transmission plate 411 near the positioning wheel 46. An extrusion spring 413 is fixedly mounted on the inner wall of the rectangular groove 412. The inner cavity of the rectangular groove 412 is horizontally slidably connected to a limited block 414 fixedly connected to the extrusion spring 413. A slot 415 that cooperates with the limit block 414 is provided on one side of the positioning wheel 46.

[0033] More specifically, the side of the limiting block 414 close to the positioning wheel 46 is arc-shaped, thereby facilitating the limiting block 414 to enter the slot 415 of the positioning wheel 46 .

[0034] One end of the bidirectional screw 49 passes through the mounting partition 4 and the cabinet 1 in sequence and extends to the outside of the cabinet 1. A handle is fixedly installed on the end of the bidirectional screw 49 extending to the outside of the cabinet 1, and the handle and the cabinet 1 are fixed by a positioning pin.

[0035] When the present invention is in use, the inner grooves 12 on both sides of the drawer box 2 correspond one-to-one with the protrusions 11 in the inner cavity of the cabinet 1. At this time, the bottom grooves 44 of the bottom wall of the drawer box 2 will abut against the multiple rollers 43 rotatably connected to the mounting partition 4. By pushing the drawer box 2, the rollers 43 can be rotated. The rotation of the rollers 43 facilitates the quick installation of the drawer box 2 into the cabinet 1.

[0036] When the drawer box 2 is pushed, the positioning wheels 46 connected to the bottom wall on both sides of the drawer box 2 will enter the sliding grooves 47 corresponding to the inner cavity of the mounting partition 4. When the drawer box 2 reaches the installation position in the inner cavity of the cabinet 1, the elastic force of the squeezing spring 413 can make the limiting block 414 enter the corresponding groove 415 in the positioning wheel 46, thereby facilitating the self-locking of the drawer box 2.

[0037] When the drawer box 2 needs to be drawn out of the cabinet 1, the limit of the drawer box 2 is first released. When the limit is released, the positioning pin in the handle is first taken out, and then the handle is turned to rotate the bidirectional screw 49. Since the threads on the outer surface of the bidirectional screw 49 are two sections with opposite rotation directions, the two screw sleeves 410 on the bidirectional screw 49 are moved in opposite directions through the thread transmission action. The movement of the two screw sleeves 410 can cause the limiting block 414 to disengage from the corresponding slot 415 in the positioning wheel 46 through the transmission plate 411. At this time, the drawer box 2 is pulled again. After being pulled to a certain distance, the transmission plate 411 can be reset by rotating the handle in the opposite direction, and then the limiting block 414 can be again entered into the corresponding slot 415 in the positioning wheel 46 by the elastic force of the extrusion spring 413, thereby facilitating the limiting of the different sliding positions of the drawer box 2, thereby reducing the probability of the drawer box 2 falling, and thus facilitating meeting the use needs of the staff.
