Description

Technical Field

[0001] The invention belongs to the technical field of square tube cabinets, and in particular relates to a cabinet structure that can be quickly spliced ​​and combined. Background Art

[0002] Early electrical equipment cabinets mainly adopted plate welding or riveting structures. Although they can meet basic protection needs, they are insufficient in mechanical strength, heat dissipation performance and installation convenience. At present, metal square tubes are gradually being used in cabinet manufacturing. Using metal square tubes as the main supporting structure can ensure that the cabinet has sufficient mechanical strength and stability, and also has good processing convenience. However, in the prior art, most cabinets need to disassemble the two side doors of the cabinet during splicing and cabinet use, which prolongs the installation time. In addition, the general splicing lock structure adopts a pull-bolt lock. Although it has high convenience of use, it is easily affected by the initial welding accuracy of the pull-bolt lock, resulting in gaps in the cabinet splicing or small splicing space, and it cannot be completely locked, which ultimately affects the flatness and sealing of the entire splicing surface.

[0003] Therefore, it is necessary to provide a cabinet structure that can be quickly spliced ​​and combined to solve the problems raised in the above background technology. Summary of the invention

When the cabinets are spliced ​​and combined, there is no need to disassemble the side doors. On the one hand, it can ensure that the internal space of each cabinet maintains a sealed independence, and on the other hand, it can shorten the installation time and reduce the workload.

[0042] In this embodiment, a limiting hole 17 is opened on one side of the locking unit 4 of the frame 1, and the cross-section of the limiting hole 17 is an inverted L-shaped structure. A positioning pin is horizontally arranged on the locking unit 4, and the positioning pin is slidably connected to the limiting hole 17; a lifting plate 18 is vertically slidably connected in the mounting groove 16, and a lifting spring 19 is connected below the lifting plate 18.

[0043] As a preferred embodiment, a guide groove 31 is provided on the locking plate 3, and the guide groove 31 is obliquely distributed; it should be noted that the installation height of the locking unit 4 is higher than the locking plate 3, and in the specific splicing and assembly, the positioning pin on the locking unit 4 is manually pushed to slide along the limiting hole. At this time, the locking unit 4 first moves horizontally and extends into the installation groove in the adjacent cabinet, and then the locking unit 4 moves vertically downward, so as to be gradually connected and assembled with the locking plate 3, and the locking unit 4 can slide along the guide groove 31, and the gap in the cabinet is gradually reduced during splicing.

[0044] In this embodiment, the locking unit 4 includes:

[0045] The main distribution plate 41 has a plurality of inner slots arranged vertically therein, each of which is fixed with a shaping plate 42, and a sliding hole is provided in the middle of the shaping plate 42;

[0046] The pull rod buckles 43 are arranged one by one corresponding to the shaping plates 42, and each of the pull rod buckles 43 is slidably connected in the sliding hole, and an inner spring 44 is sleeved on the pull rod buckle 43;

[0049] The T-shaped bar 5 is fixed on the side wall of the main distribution plate 41 , and a connecting groove 51 is correspondingly opened in the locking plate 3 , and the T-shaped bar 4 is slidably connected to the connecting groove 51 .

[0050] In this embodiment, the inner spring 44 pulls the pull rod buckle 43 to slide toward the side close to the lock plate 3 under the action of elastic force; the lock plate 3 has stop blocks 32 fixed on both sides inside, and the stop blocks 32 limit the end of the pull rod buckle 43;

[0051] The upper and lower sides of the end of the pull rod buckle 43 are set as arc structures, so that when the main matching plate 41 and the lock plate 3 are slidably assembled, the pull rod buckle 43 can freely slide up and down along the guide groove 31 of the lock plate 3;

[0052] The length of the pull rod buckle 43 gradually increases from top to bottom, that is, the connection and assembly between the lock unit 4 and the lock plate 3 is mainly achieved by sliding a plurality of arranged pull rod buckles 43 along the guide groove 31. When the two cabinets are almost seamlessly spliced, the corresponding pull rod buckles 43 are at each stop block 32, and the stop blocks 32 form a horizontal limit lock on the pull rod buckle 43, thereby ensuring a high-strength splicing and locking between the two cabinets.

[0053] In the present embodiment, the locking unit 4 and the locking plate 3 are gradually slidably connected, the distance between the main distribution board 41 and the locking plate 3 is gradually reduced, and each pull rod buckle 43 contacts and locks with the stop block 32 in the locking plate 3 in sequence; and the effective locking number of the pull rod buckle 43 and the stop block 32 in the present invention can increase as the cabinet gap becomes smaller, that is, as the splicing gap decreases, more locking points will be activated, which significantly enhances the connection strength and reduces the possibility of loosening; and the presence of multiple locking points provides a redundant design, even if some locking points fail, other locking points can still ensure sufficient connection strength.

[0054] As a preferred embodiment, the main distribution plate 41 is vertically provided with an inner straight groove, a linkage rod 6 is slidably connected in the inner straight groove, and the positioning pin 61 is fixed to the linkage rod;

[0055] A plurality of side top shafts 62 corresponding to the dial plate 45 are distributed on the side wall of the linkage rod 6, and one end of each side top shaft 62 is vertically fixed on the linkage rod 6;

[0056] A fixing piece 63 is fixed on the slider 48 in each of the dial plates 45 , and the other end of the side top shaft 62 is in contact with the fixing piece 63 , and the contact surface thereof is set to be an inclined structure.

[0057] In this embodiment, a compression spring is connected to the upper end of the linkage rod 6, and the other end of the compression spring is connected to the side wall of the inner straight groove; the compression spring can press the linkage rod 6 vertically downward under the action of elastic force, and at this time, the side top shafts 62 on the linkage rod 6 drive the slider 48 to slide to the side away from the positioning pin 61 through the inclined contact with the fixing member 63; that is to say, during the specific splicing, when the two cabinets are completely and initially docked and positioned, the lock unit 4 in one of the cabinets is moved along the limiting hole 17 through the positioning pin 61, and at this time, the T-shaped bar 5 on the main distribution plate 41 can be slidably assembled with the connecting groove 51, and because the positioning pin 61 is only subjected to horizontal and vertical downward thrusts, the compression spring on the linkage rod 6 is in a spring-supported state, so that the levers 46 in each adjustment plate 45 on the main distribution plate 41 can A horizontal pulling effect is provided to the pull rod buckle 43, and the stop block 32 forms a horizontal limit lock for the pull rod buckle 43. At the same time, the arc-shaped surface on the lower side of each pull rod buckle 43 can ensure that the pull rod buckle 43 can slide downward along the guide groove 31 normally. When the cabinets are almost seamlessly spliced, multiple pull rod buckles 43 are at the stop blocks 32 at corresponding positions, thereby forming multiple locking points, which significantly enhances the connection strength; and during splicing and disassembly; the positioning pin is manually adjusted, and the positioning pin 61 is pushed vertically upward by water. The compression spring on the linkage rod 6 is in a compressed state, and the lever 46 in the dial plate 45 has a small horizontal pulling force on the pull rod buckle 43. The pull rod buckle 43 can be pulled away from the stop block 32 under the action of the elastic force of the inner spring 44, which facilitates the pull rod buckle and the stop block 32 to achieve a certain separation effect, thereby improving the lubricity of pulling and disassembly.
