Description

Technical Field

[0001] The utility model relates to an invisible connection structure for installing a stainless steel cabinet, belonging to the technical field of connecting pieces. Background Art

[0002] During the assembly process of the cabinet, the partitions are connected by connecting pieces. In order to make the cabinet have a good appearance and be easy to disassemble and assemble, a stainless steel cabinet invisible connecting telescopic piece disclosed in application number CN202322287715.7 appears. A telescopic rod with a limit head is installed in one connecting plate, and a matching connecting piece is installed in another connecting plate. The two connecting plates are connected to the connecting piece through the telescopic rod to achieve installation. In order to make the two connecting plates tightly connected and the connecting structure not exposed, a groove needs to be opened on the connecting plate, and the connecting piece is installed in the groove. It is more convenient to open the groove on a wooden connecting plate, but it is not convenient to open the groove directly on a metal such as stainless steel. It is difficult to achieve this with metal connecting plates, and it is necessary to set a flange structure or an outer frame on metal connecting plates such as stainless steel, which makes the structure complicated, the integrity is poor, and the production cost is greatly increased. In addition, a card joint type connection structure has also appeared, that is, a movable card joint is installed on a connecting plate, and the card joint will deform and expand / contract during the movement, and a matching card connector is installed in the other connecting plate. The problem with this connection structure is that there are tolerances or errors in the production and assembly process, resulting in differences in the gap between the two connecting plates. When the card joint moves to the clamping state, it cannot be exactly clamped with the clamping part, which is prone to poor connection. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide an invisible connection structure for installing a stainless steel cabinet, which does not require slotting on a connection plate and can ensure a tight fitting connection of the connection plate, thereby solving the deficiencies of the prior art.

[0004] The technical solution of the utility model is: an invisible connection structure for installing a stainless steel cabinet, including a first embedded part, the first embedded part includes a sleeve, a spring installed in the sleeve and a telescopic rod, one end of the telescopic rod has a clamping joint, the telescopic rod can slide relative to the sleeve to make the clamping joint enter and exit the sleeve, including a second embedded part coaxially distributed with the first embedded part, the second embedded part includes an installation tube, a clamping part slidably connected to the installation tube, the installation tube is provided with a driving mechanism for driving the clamping part to slide axially, one end of the clamping part has two opposing elastic clips, the two opposing elastic clips are expanded / contracted by deformation to achieve a clamping connection with the clamping joint of the telescopic rod.

[0005] Furthermore, the installation tube is installed with a fixing piece, and the fixing piece is located between the two elastic clips. When the clamping piece slides relative to the installation tube, it resists the fixing piece and opens the two elastic clips.

[0006] The driving mechanism further comprises a gear connected to the mounting cylinder, and the clamping member comprises a rack portion meshing with the gear.

[0007] The driving mechanism further comprises a guide screw threadedly connected to the mounting tube, and a return spring arranged on the mounting tube and connected to the clamping member, wherein the clamping member has a guide surface cooperating with the guide screw.

[0008] Furthermore, a cover cap is installed on the gear to cover it.

[0009] Furthermore, a cover cap is installed on the guide screw to cover it.

[0010] Furthermore, the sleeve of the first embedded part and the mounting sleeve of the second embedded part have a connecting structure for fixing on a mounting plate.

[0011] By implementing the utility model, the first embedded part and the second embedded part are respectively embedded in the two mounting plates to be connected, and the mounting plate in which the first embedded part is embedded moves relative to the other mounting plate. During this process, the telescopic rod of the first embedded part is blocked by the other mounting plate, and the telescopic rod is restricted in the sleeve. At this time, the spring is compressed. When the first embedded part and the second embedded part are moved to be relatively aligned on the same axis, the spring pushes the telescopic rod to move outward so that the clamping joint at the outer end of the telescopic rod enters the mounting tube of the second embedded part. The driving mechanism drives the clamping part to slide in the mounting tube, so that one end of the elastic clip of the clamping part is clamped with the clamping joint of the telescopic rod, and the clamping part is kept in the clamped position and remains motionless, thereby achieving a tight fit between the connecting plates.

[0018] Embodiments of the present utility model: Figures 1 to 5 As shown, an invisible connection structure for installing a stainless steel cabinet comprises a first embedded part, which is a prior art and comprises a sleeve 1, a spring 2 and a telescopic rod 3 installed in the sleeve 1, one end of the telescopic rod 3 has a clamping joint 4, and the telescopic rod 3 can slide relative to the sleeve 1 to make the clamping joint 4 enter and exit the sleeve 1. The present application comprises a second embedded part that cooperates with the first embedded part, wherein the second embedded part comprises a mounting tube 6, a clamping part 7 that is slidably connected in the mounting tube 6, and a driving mechanism for driving the clamping part 7 to slide axially is provided on the mounting tube 6. One end of the clamping part 7 has two opposite elastic clips 8, and the two opposite elastic clips 8 are expanded / contracted by deformation to achieve clamping with the clamping joint 4 of the telescopic rod 3. Specifically, the sleeve 1 of the first embedded part and the mounting tube 6 of the second embedded part are provided with an external thread or a mounting portion 16 with a screw hole, and the first embedded part The first embedded part and the second embedded part are embedded in the two mounting plates to be connected by threaded connection or screw fixation. The mounting plate embedded with the first embedded part is pressed against the other mounting plate and then moved. During this process, the telescopic rod 3 of the first embedded part is blocked by the other mounting plate, and the telescopic rod 3 is restricted in the sleeve 1. At this time, the spring 2 is compressed. When the first embedded part and the second embedded part are moved to be relatively aligned on the same axis, the spring 2 pushes the telescopic rod 3 to move outward so that the clamping joint 4 at the outer end of the telescopic rod 3 enters the mounting tube 6 of the second embedded part. The driving mechanism drives the clamping part 7 to slide in the mounting tube 6, so that the clamping part 7 is provided with one end of the elastic clip 8 and is clamped with the clamping joint 4 of the telescopic rod 3, and the clamping part 7 is kept in the position after clamping and remains motionless. In the case where there is a difference in the gap between the two connecting plates, a perfect connection can be achieved without grooving the connecting plate.

[0019] As a preferred embodiment, the mounting tube 6 is installed with a fixing part 9, and the fixing part 9 is located between the two elastic clips 8. When connecting, the driving mechanism first drives the clamping part 7 to move outward and contact with the fixing part 9 to stretch the two elastic clips 8 apart, so that the clamping joint 4 of the telescopic rod 3 can easily enter between the two elastic clips 8, and then drives the clamping part 7 to move inward and separate from the fixing part 9. The two elastic clips 8 are reset and retracted and continue to move to the position where the clamping joint 4 is just clamped. The two elastic clips 8 are stretched apart by the fixing part 9, instead of the clamping joint 4 of the telescopic rod 3 being rigidly clamped with the two elastic clips 8, which facilitates the connection between the two.

[0020] The driving mechanism of the present application only needs to be able to drive the clamping member 7 to move axially in the mounting tube 6 and stop at a desired position. Figures 3 to 5 As shown, a gear 10 is connected to the mounting tube 6, and one end of the gear 10 is located outside the mounting tube 6, which is convenient for rotating the gear 10. The clamping member 7 has a rack portion 15 meshing with the gear 10. The clamping member 7 can be moved inward / outward by rotating the gear 10 clockwise or counterclockwise; Figures 1 to 2As shown, the driving mechanism may also include a guide screw 11 threadedly connected to the mounting tube 6, a reset spring 12 provided on the mounting tube 6 and connected to the clamping member 7, the clamping member 7 has a guide surface 13 matched with the guide screw 11, when the guide screw 11 is loosened, the reset spring 12 pushes the clamping member 7 to move outward, so that the fixing member 9 blocks the clamping member 7, and the two elastic clips 8 of the clamping member 7 are in an open state, when matched, after the clamping joint 4 of the telescopic rod 3 enters the two elastic clips 8, the guide screw 11 is tightened, and the guide screw 11 cooperates with the guide surface 13 of the clamping member 7 to push the clamping member 7 inward, and the two elastic clips 8 are reset and retracted and continue to move to a position where the clamping joint 4 is just clamped.

[0021] In order to prevent the gear 10 or the guide screw 11 from being exposed to the outside, a cover cap 14 can be installed on the gear 10 or the guide screw 11 to cover it. For example, a hexagonal hole is provided on the gear 10 or the guide screw 11 to realize the rotation operation, and the cover cap 14 is inserted into the inner hexagonal hole for easy disassembly and assembly.
