[0002] As an important equipment for power distribution, low-voltage cabinet plays an important role in modern power distribution network and engineering construction. A low-voltage cabinet is usually equipped with multiple drawers. In order to ensure the stability of the drawers during use and movement, rollers are set on the sides of the drawers, and the drawer placement chamber on the cabinet body is provided with a slide groove adapted to the rollers.

[0003] However, in actual use, in order to ensure that the drawer can be accurately positioned after being pushed in, the above-mentioned rollers and slide grooves need to have a high degree of adaptability. As a result, it is difficult for the staff to find the correct pushing position when assembling the drawer, which can easily damage the rollers. Secondly, due to the deviation in the matching position of the rollers and the slide grooves, greater resistance is likely to be generated during the push-in process of the drawer. This is very likely to cause damage to the components in the drawer due to violent operation by some staff, thereby causing losses. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0036] See also Figure 1-Figure 8 In an embodiment of the present invention, a drawer structure of a low-voltage cabinet includes a drawer body 1 and an integrated frame adapted to the drawer body 1, the integrated frame is installed in the drawer placement chamber of the low-voltage cabinet, and further, the two wall panels 2 are provided with a plurality of mounting holes, and in actual production, the staff can fix the wall panels 2 to the drawer placement chamber of the low-voltage cabinet through the mounting holes. The integrated frame includes two oppositely arranged wall panels 2 and a plurality of connecting rods 3 connecting the two wall panels 2, a roller 101 is respectively provided on both sides of the drawer body 1, and a guide plate 4 is respectively provided on the inner walls of the two wall panels 2, and a guide groove 401 is provided on the guide plate 4, and the cross-sectional throughput of the guide groove 401 is greater than the rolling space occupied by the roller 101;

[0037] The drawer structure of the low-voltage cabinet also includes:

[0038] An elastic transverse movement mechanism is provided with one group on each inner wall of the two wall panels 2. The elastic transverse movement mechanism is connected to a pressure-limiting mechanism. The elastic transverse movement mechanism is triggered after the drawer body 1 is pushed into the integrated frame through the roller 101 and the guide groove 401, and can prompt the pressure-limiting mechanism to perform regular actions on the drawer body 1. At the same time, the two groups of locking mechanisms arranged on the drawer body 1 can be locked with the two wall panels 2 respectively.

[0039] The cross-sectional throughput of the guide groove 401 is greater than the rolling space occupied by the roller 101, that is, the width of the guide groove 401 is greater than the diameter of the roller 101, and the cross-sectional width of the guide groove 401 is greater than the thickness of the roller 101. Therefore, by increasing the size of the guide groove 401, when the drawer body 1 needs to be pushed in, compared with the existing drawer guide means (that is, the guide wheel and the guide rail are fully adapted), the staff can find the position more quickly. At the same time, during the process of pushing the drawer body 1 in, a margin is left in the guide groove 401, so the smoothness of the process of pushing the drawer body 1 can be significantly improved;

[0040] During the process of pushing the drawer body 1, the elastic transverse movement mechanism is triggered and will move along the length direction of the wall panel 2. During the process of pushing the drawer body 1, the pressure-limiting mechanism is triggered to apply pressure to the drawer body 1. The pressure on the drawer body 1 is divided into a downward force component and a force component toward the middle of the two wall panels 2. Therefore, the drawer body 1 can be centered between the two wall panels 2 to ensure the stable assembly of the drawer body 1 and avoid the drawer body 1 from loosening. Finally, after the drawer body 1 is pushed to the end of the stroke and the plug on its rear end face is connected to the socket in the cabinet, the drawer body 1 can be locked with the wall panel 2 through the locking mechanism.

[0041] In summary, the drawer structure increases the size of the guide groove 401 that cooperates with the roller 101, so that when the drawer body 1 needs to be pushed in, the staff can quickly find the correct position, and during the pushing process of the drawer body 1, a margin is left in the guide groove 401, thereby significantly improving the smoothness of the push-in process of the drawer body 1. During the pushing process of the drawer body 1, the pressure limiting mechanism can stabilize the drawer body 1 to regularize the position of the drawer body 1, and finally the locking mechanism locks the drawer body 1 with the wall panel 2. Through the mutual cooperation between various mechanisms and components, the drawer structure is easy to use and its smoothness when pushed in is significantly improved, thereby avoiding damage to components inside the drawer due to violent operation of the operator when resistance occurs during the pushing process.

[0042] Please refer again Figure 2 , Figure 5 as well as Figure 6 The elastic transverse movement mechanism includes a driven plate 17 movably arranged on the wall panel 2, and the driven plate 17 cooperates with a column 10 fixed to the side of the drawer body 1. The driven plate 17 is connected to two groups of elastic telescopic parts installed on the wall panel 2, and a two-way telescopic component connected to the pressure limiting mechanism is provided on the driven plate 17.

[0043] In detail, the elastic telescopic member includes a cylinder 13 fixed on the inner wall of the wall panel 2, a telescopic rod 14 slidably fitted with the cylinder 13, and a second cylindrical spring 16 sleeved on the outer circumference of the telescopic rod 14, one end of the telescopic rod 14 is connected to the driven plate 17, and the other end is fixed to a table 15 slidably arranged inside the cylinder 13, and one end of the second cylindrical spring 16 is connected to the table 15, and the other end is connected to the inner wall of the cylinder 13.

[0044] The wall plate 2 is provided with a guide frame 27, and the pressure limiting mechanism includes a connecting block 28 slidably embedded in the guide frame 27, a second triangular block 12 installed at an end of the connecting block 28 away from the wall plate 2, and a cross bar 26 installed at the bottom of the connecting block 28. The second triangular block 12 cooperates with the first triangular block 11 fixed to the side of the drawer body 1, and the cross bar 26 is slidably connected to a transmission block 23, and the transmission block 23 is connected to the two-way telescopic assembly.

[0045] A slider 18 is slidably engaged with the driven plate 17, and the bidirectional telescopic assembly includes two movable cylinder members 19 fixed to the slider 18 and two vertical rods 20 slidably engaged with the two movable cylinder members 19 respectively. The vertical rod 20 is fixed to a ring body 1901 slidably arranged inside the movable cylinder member 19, and the outer periphery of the vertical rod 20 is sleeved with a third cylindrical spring 21 and a fourth cylindrical spring 22 respectively located on both sides of the ring body 1901, the head ends of the third cylindrical spring 21 and the fourth cylindrical spring 22 are connected to the ring body 1901, and the tail ends abut against the inner wall of the movable cylinder member 19.

[0046] When the drawer body 1 is pushed in, after the column 10 contacts the driven plate 17, the column 10 will push the driven plate 17 to move together. Accordingly, the driven plate 17 drives the telescopic rod 14 to slide toward the outside of the cylinder 13, the second cylindrical spring 16 is compressed, and the transmission block 23 slides along the length direction of the cross bar 26. At this time, the movable cylinder 19 will slide downward on the driven plate 17, and the third cylindrical spring 21 is compressed. When the plug on the rear end face of the drawer body 1 is close to the socket in the cabinet, the third cylindrical spring 21 is compressed. The vertical rod 20 moves downward, and the transmission block 23 pulls the cross bar 26 and the connecting block 28 downward, so that the inclined surfaces of the second triangular block 12 and the first triangular block 11 are tightly attached, and the pressure on the first triangular block 11 is decomposed into a downward component and a component toward the middle of the two wall panels 2. Therefore, the drawer body 1 can be automatically regularized to ensure that the plug on the rear end face of the drawer body 1 can be aligned with the socket in the cabinet. Finally, the operator continues to push the drawer body 1 for a short distance to complete the docking of the plug and the socket.

[0047] It should be added that, in a specific implementation, after the second triangular block 12 acts on the first triangular block 11, the resistance when the operator finally pushes the drawer body 1 will be significantly increased, thereby being able to effectively prompt the operator, so that when the plug on the rear end face of the drawer body 1 is combined with the socket in the cabinet, a deceleration effect is achieved, thereby preventing the operator's excessive thrust from causing damage to the plug and the socket.

[0048] The slider 18 is provided with a first boss 24, and the ends of the two uprights 20 away from the transmission block 23 are fixed with a second boss 25, and the first boss 24 and the second boss 25 extend into the guide groove and the rectangular groove provided on the wall plate 2, respectively, and are slidably connected with the wall plate 2. Figure 8The rectangular slot body includes a first slide slot 201, a second slide slot 202, a third slide slot 203 and a fourth slide slot 204 which are connected to each other. The guide slot body includes an inclined section 205 and a straight section 207 which are connected to each other.

[0049] Specifically, after the column 10 contacts the driven plate 17, as the operator pushes the drawer body 1, the column 10 pushes the driven plate 17 to move together, and accordingly, the first boss 24 slides along the inclined section 205. Since the second boss 25 is located in the first slide groove 201 at this time, the vertical rod 20 cannot move in the vertical direction, so the first boss 24 slides with the wall plate 2 through the inclined section 205, and the first boss 24 drives the slider 18 to move downward on the driven plate 17, and the movable cylinder 19 moves downward with the slider 18, and then the third cylindrical spring 21 is compressed;

[0050] When the first protrusion 24 moves to the end of the straight section 207 close to the inclined section 205, the plug on the rear end face of the drawer body 1 is close to the socket in the cabinet (the displacement distance between the two is less than the width of the second slide groove 202), and the second protrusion 25 moves to the second slide groove 202. Therefore, the third column spring 21 rebounds, and the vertical rod 20 moves downward, so that the second protrusion 25 passes through the second slide groove 202 and drops into the third slide groove 203. Correspondingly, the vertical rod 20 can pull the cross bar 26 and the connecting block 28 downward through the transmission block 23, so that the inclined surfaces of the second triangular block 12 and the first triangular block 11 are attached to each other, so that the drawer body 1 is subjected to force and automatically regularized, so that the plug on the rear end face of the drawer body 1 is aligned with the socket in the cabinet.

[0051] It should be emphasized that the second slide groove 202 is wider than the third slide groove 203, the first slide groove 201 and the fourth slide groove 204. The reason for setting the width of the second slide groove 202 to be larger is that after the above operation, the operator can continue to push the drawer body 1 so that the plug on the rear end surface of the drawer body 1 can be smoothly combined with the socket in the cabinet.

[0052] When the drawer body 1 needs to be pulled out, the locking mechanism releases the locking state of the drawer body 1 and the wall panel 2, and then the drawer body 1 can be pulled outward. At this time, the second cylindrical spring 16 rebounds (the elastic coefficient of the second cylindrical spring 16 is relatively large), and the first boss 24 slides along the straight section 207. After the first boss 24 slides into the inclined section 205, the movable cylinder 19 moves upward, and the fourth cylindrical spring 22 is compressed until the second boss 25 enters the fourth slide groove 204. The fourth cylindrical spring 22 rebounds, causing the vertical rod 20 to rise, and the second boss 25 is reset to the connection between the fourth slide groove 204 and the first slide groove 201, and the second triangular block 12 is lifted and separated from the first triangular block 11.

[0053] Please refer again Figure 8 The locking mechanism comprises a guide cylinder 5 rotatably mounted on the drawer body 1, a rotary rod 7 slidably fitted with the guide cylinder 5, and a locking member 6 fixed with the rotary rod 7. The wall plate 2 is provided with a slot 206 adapted to the locking member 6. The rotary rod 7 is also connected to an elastic positioning member provided inside the guide cylinder 5. The elastic positioning member comprises a boss 8 slidably provided in the guide cylinder 5 and fixed with the rotary rod 7, and a first cylindrical spring 9 provided inside the guide cylinder 5. One end of the first cylindrical spring 9 is connected to the boss 8, and the other end is connected to the inner wall of the guide cylinder 5. The boss 8 is also provided with two protrusions, and the inner wall of the guide cylinder 5 is provided with two strip grooves adapted to the protrusions.

[0054] Finally, the operator pushes the drawer body 1 so that the plug on the rear end surface of the drawer body 1 is smoothly combined with the socket in the cabinet. Then, the operator pushes the rotary rod 7 toward the inside of the drawer body 1. Accordingly, the rotary rod 7 drives the boss 8 to slide in the guide cylinder 5 and compresses the first cylindrical spring 9. When the compression amount of the first cylindrical spring 9 reaches the maximum, the rotary rod 7 cannot be pushed. At this time, the locking member 6 is aligned with the card slot 206. The operator rotates the rotary rod 7 again so that the locking member 6 is stuck in the card slot 206.

[0055] Among them, the purpose of setting a raised portion on the raised platform 8 and setting a strip groove on the inner wall of the guide cylinder 5 is to ensure that the guide cylinder 5 can rotate synchronously with the rotary rod 7 to avoid distortion of the first columnar spring 9. Because the first columnar spring 9 is in a compressed state after the locking member 6 is inserted into the slot 206, the elastic support of the first columnar spring 9 can effectively ensure the stability of the locking member 6 in the slot 206 to avoid the locking member 6 and the slot 206 from falling off accidentally.

[0056] As another embodiment of the present invention, a method for installing a drawer structure of a low-voltage cabinet is also proposed, comprising the following steps:

[0057] Step 1: Install the integrated frame into the drawer of the low-voltage cabinet;

[0058] Step 2: The roller 101 enters the guide groove 401 to push the drawer body 1 to move into the placement chamber;

[0059] Step 3: The elastic transverse movement mechanism is triggered, and when the plug on the drawer body 1 is close to the socket in the chamber, the pressure limiting mechanism is triggered to regularize the drawer body 1;

[0060] Step 4: Continue to push the drawer body 1 so that the plug on the drawer body 1 is connected to the socket in the chamber;

[0061] Step five: lock the drawer body 1 and the two wall panels 2 through a locking mechanism.

[0062] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
