Description

Technical Field

[0001] The invention relates to a clamping structure, in particular to a magnetically controlled clamping structure. Background Art

[0002] The clamping structure is a widely used connection method for connecting parts. The common clamping structure at present is to directly fix the installed parts on the installation surface with a buckle, and the buckle needs to be manually operated to control the opening and closing of the buckle. Chinese utility model patent document CN220791675U discloses a high-strength connection structure of an intelligent storage shelf, which is a clamping structure, including a connecting member and a cross bar, a clamping groove is fixedly opened on one side of the connecting member, and the cross bar can be placed inside the clamping groove. A clamping box is fixedly installed on both sides of the width direction of the connecting member, and the clamping box leads to the inside of the clamping groove. A movable plate, a clamping block, a reset spring and a pull rod are arranged inside the clamping box, wherein the clamping block extends into the inside of the clamping groove under the restriction of the reset spring, and the cross bar is correspondingly provided with a clamping groove to accommodate the clamping block. When the cross bar is inserted into the clamping groove, the clamping block falls into the clamping groove of the cross bar, that is, the clamping is completed, and a pull rod is arranged inside the clamping box, and the clamping block can be pulled back into the clamping box by pulling the pull rod to release the clamping.

[0003] The clamping structure in the above technical solution has the following disadvantages: 1. The clamping needs to be released by manually pulling the pull rod, which is quite laborious; 2. For ease of operation, the pull rod is exposed outside the component, which not only poses a risk of damage by accidental collision or human damage, but also affects the appearance. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a magnetically controlled snap-in structure, which saves effort in releasing the operation and makes the product more aesthetically pleasing when applied to the product.

[0005] In order to solve the above technical problems, the present invention provides a magnetically controlled clamping structure, including a clamping ring and a clamping column that can be axially inserted and installed in the clamping ring, a clamping block is provided on the side of the clamping ring, the clamping block radially extends into the clamping ring, and an annular clamping groove is correspondingly opened on the clamping column; the clamping column is inserted into the clamping ring, and the clamping block is radially pushed during the insertion process to make it radially avoid, until the clamping groove is aligned with the clamping block, then the clamping block automatically resets and clamps into the clamping groove to realize clamping; the clamping block is made of a material that can be subjected to magnetic force, and can be subjected to magnetic force to achieve radial avoidance and leave the clamping groove, thereby releasing the clamping.

[0006] Furthermore, the reset member drives the clamping block to achieve automatic reset.

[0007] Further, the return element is a return spring.

[0008] Furthermore, a concave hole is formed on the clamping block, and the reset member extends into the concave hole.

[0009] Furthermore, the magnetically controlled snap-in structure comprises a snap-in box, the front part of the snap-in box is the snap-in ring, and the snap-in block and the reset member are located inside the snap-in box.

[0010] Furthermore, the clamping post and the clamping box are made of a material that is not affected by magnetic force.

[0011] Furthermore, a mounting plate for installation and fixing is provided, and the clamping column is installed on the mounting plate.

[0012] Furthermore, the clamping column is perpendicular to the mounting plate.

[0013] Furthermore, a mounting plate for installation and fixing is provided, and the clamping ring is mounted on the mounting plate.

[0014] Further, the clamping ring is axially parallel to the mounting plate.

[0015] By adopting such a structure, firstly, when it is applied to fields such as furniture where the aesthetics of the product needs to be considered, since the snap-in structure only needs to use magnetic suction to control the snap-in block to release the snap-in, there is no need to manually touch the snap-in block for operation. Therefore, there is no need to set a pull rod exposed on the surface of the product for the snap-in block, which not only avoids accidental collision or human damage, but also makes the product more aesthetically pleasing. In addition, the release of the snap-in is controlled by magnetic suction, and there is no need to manually pull the pull rod, which is more labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention is further described in detail below in conjunction with specific implementation methods.

[0025] Card connection structure Figure 1 and Figure 2 As shown, the clamping column 1 is vertically mounted on a mounting plate 4 for mounting and fixing, and the clamping box 2 is mounted on a mounting plate 5 for mounting and fixing. Figure 3 As shown, the front of the snap-in box 2 is provided with a snap-in ring 25, and the snap-in ring 25 is axially parallel to the mounting plate 5. The rear of the snap-in box 2 is provided with a U-shaped snap-in block 21, as shown in FIG. Figure 5 As shown, the clamping block 21 is mounted on the rectangular baffle 211. Figure 6 As shown, a connecting hole 26 is opened on the side of the clamping ring 25, and the clamping block 21 radially extends into the clamping ring 25 from the connecting hole 26. The clamping column 1 is axially inserted into the clamping ring 25, and the clamping block 21 is radially pushed during the insertion process, so that the clamping block 21 avoids in the radial direction. Figure 4 As shown, the bottom surface of the clamping block 21 is symmetrically provided with four recessed holes 23, which are evenly distributed. The front ends of the four return springs 22 extend into the recessed holes 23 respectively, and the rear ends abut against the bottom 24 of the clamping box 2. Figure 3 As shown, the reset spring 22 is compressed due to the radial avoidance of the clamping block 21. An annular clamping groove 3 is opened around the side wall in the middle of the clamping column 1. During the insertion process of the clamping column 1, the clamping block 21 is radially pushed until its clamping groove 3 is aligned with the clamping block 21. The reset spring 22 serves as a reset member of the clamping block 21, driving the clamping block 21 to automatically reset radially so that it is clamped into the clamping groove 3 to achieve clamping. When the clamping needs to be released, Figure 7 As shown, a magnet 27 is placed on the back of the box bottom 24. The clamping block 21 is made of stainless steel that is subject to magnetic force. The clamping block 21 will be attracted by the magnet 27 and radially avoid leaving the clamping groove 3, thereby releasing the clamping, and the clamping column 1 can be retracted outside the clamping ring 25. The clamping column 1 and the clamping box 2 should be made of stainless steel that is not subject to magnetic force, so as not to affect the magnetic effect of the clamping block 21.

[0026] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
