Description

Technical Field

[0001] This utility model relates to the field of locking structure technology, specifically a magnetic positioning quick locking structure. Background Technology

[0002] A locking device is a means of quickly and reliably securing or releasing mechanical parts, commonly found in industrial and automated equipment as well as everyday consumer goods. Its core function is to achieve tool-free fastening and disassembly through a mechanical structure.

[0003] The working principle of a locking device is to convert external force into clamping force through an internal mechanical structure, thereby achieving self-locking or quick release. For example, a thumb-type locking device compresses a spring by rotating a knob to push the clamping plate.

[0004] Existing locking devices are basically axially rotating and locked by a knob, or by a spring and steel ball. In actual use, the above-mentioned locking devices are suitable for places with axial space, but not for products with no axial operating space. Therefore, the overall structure has limited applicable environment and reduces the effectiveness of use. To address this, this utility model proposes a magnetic positioning quick locking structure. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic positioning quick-locking structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetic positioning quick-locking structure, comprising a locking shell, a conical groove inside the locking shell, a directional protrusion on one inner wall of the conical groove, a first magnet fixedly installed at the tail end of the conical groove inside the locking shell, a plunger hole on the outer wall of the locking shell, a rotating plunger inside the plunger hole, a conical component adapted to the conical groove on the outside of the locking shell, a second magnet fixedly installed inside the conical component, a directional groove on the side of the conical component, and a locking hole on the outer wall of the conical component.

[0007] Preferably, the tapered groove and the tapered component are in clearance fit.

[0008] Preferably, a screw hole is provided at the center of the inside of the tapered component.

[0009] Preferably, a positioning pin hole with unequal distances from the center is provided on the outer side of the screw hole and inside the tapered member.

[0010] Preferably, the first magnet and the second magnet are strong magnets that attract each other.

[0011] Preferably, a locking pin is fixedly installed on the lower surface of the bottom end of the rotating plunger.

[0012] Preferably, a fixing hole is provided on the outer surface of the tail end of the locking shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The locking structure of this utility model uses the cooperation between the conical structures to ensure a tight fit between the conical surfaces. This connection structure has no frame and will not wobble, effectively improving stability. It can be positioned and attracted by a strong magnet, so that the conical part and the locking shell can be firmly attracted together.

[0015] Meanwhile, the rotating plunger can lock the structure, which solves the problem of insufficient magnetic attraction in a limited space, improves the connection strength, and the plunger locking combined with the strong attraction of the magnet can meet the needs of both large and small forces in actual use, thus improving applicability.

[0016] Furthermore, this utility model, by providing directional limiting protrusions and grooves on the conical groove and the conical part, can effectively prevent the problem of mutual rotation between the locking shell and the conical part through the cooperation of the protrusions and grooves, and has a good limiting effect.

[0017] In summary, the locking structure of this utility model, through magnetic attraction and rotating plunger structure, realizes the fastening and connection between two structural components or products. At the same time, the insert-type hidden locking connection can effectively solve the problem that traditional locking devices are unsuitable and cannot be connected when there is no axial operating space. This effectively improves the applicability of the locking structure, reduces usage limitations, and improves the performance. Furthermore, through the use of conical surfaces, a frameless fit connection between two structural components can be achieved, preventing shaking and effectively improving stability. The protrusions and grooves on the conical surfaces achieve structural orientation, preventing mutual rotation between the connecting parts. Attached Figure Description

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-5 An embodiment of this utility model is provided: a magnetic positioning quick locking structure, including a locking shell 1, a conical groove 2 is provided inside the locking shell 1, a directional protrusion 6 is provided on one side inner wall of the conical groove 2, a magnet 3 is fixedly installed at the tail end of the conical groove 2 and inside the locking shell 1, a plunger hole 4 is provided on the outer wall of the locking shell 1, a rotating plunger 5 is provided in the plunger hole 4, and a locking pin is fixedly installed on the lower surface of the bottom end of the rotating plunger 5.

[0028] Furthermore, the locking shell 1 is provided with a conical part 7 that is adapted to the conical groove 2. The conical groove 2 and the conical part 7 are fitted with a gap. In use, the conical part 7 can be inserted into the conical groove 2 of the locking shell 1. In order to ensure the magnetic adsorption and positioning effect, a second magnet 13 is fixedly installed inside the conical part 7. The first magnet 3 and the second magnet 13 are strong magnets that attract each other. Thus, the conical part 7 can achieve a certain positioning and connection effect through the magnetic adsorption between the two magnets after being inserted into the conical groove 2 of the locking shell 1.

[0029] In this embodiment, the tapered member 7 has a directional groove 12 on its side. The directional groove 12 can cooperate with the directional protrusion 6 when the tapered member 7 is inserted, thereby having a certain directional limiting effect and preventing the tapered member 7 from rotating in the tapered groove 2.

[0030] In this embodiment, in order to limit and lock the tapered part 7 and avoid increasing the strength of the fastening connection, a locking hole 9 is provided on the outer wall of the tapered part 7;

[0031] In this structural design, after the conical part 7 is inserted into the conical groove 2, the plunger hole 4 can be aligned with the locking hole 9. Then, a rotating plunger 5 is installed in the two aligned holes. The locking pin at the bottom of the rotating plunger 5 can be inserted between the two holes, thus achieving a certain positioning and locking effect. This prevents the conical part 7 from dislodging from the conical groove 2, providing a good fastening and locking effect and improving the structural connection strength. For specific details, please refer to the attached instruction manual. Figure 5 As shown.

[0032] In this embodiment, a screw hole 8 is provided at the center of the conical part 7, and a positioning pin hole 10 with unequal distances from the center is provided on the outside of the screw hole 8 and inside the conical part 7. The unequal distance positioning pin hole 10 can serve as a reminder for installation in either direction. After the conical part 7 is installed, the locking hole 9 can be aligned with the plunger hole 4 to avoid reverse installation of the conical part, improve the structural fit and use effect, and have a good installation reminder function. The screw hole 8 can cooperate with the positioning pin hole 10 to fix the conical part 7 on the external product.

[0033] In this embodiment, in order to facilitate the installation of the locking shell 1, a fixing hole 11 is provided on the outer surface of the tail end of the locking shell 1.

[0034] Working principle: When the quick locking structure of this utility model is in use, the locking shell 1 can be installed on one of the products that need to be connected through the fixing hole 11, while the conical part 7 can be installed on another product that needs to be connected through the screw hole 8 and the positioning pin hole 10. In this way, the locking shell 1 and the conical part 7 can be installed on two products respectively.

[0035] Then, the conical piece 7 is inserted into the conical groove 2 of the locking shell 1. During the insertion of the conical piece 7, the positioning groove 12 and the positioning protrusion 6 need to be aligned, and one side of the locking hole 9 and one end of the plunger hole 4 should be in the same direction to avoid reverse installation when the conical piece 7 is inserted.

[0036] During the insertion of the conical piece 7, the first magnet 3 inside the locking shell 1 can attract each other with the second magnet 13 inside the conical piece 7, thereby achieving a certain magnetic positioning effect.

[0037] After magnet 3 and magnet 13 attract each other, the plunger hole 4 can be aligned vertically with the locking hole 9. Then, the rotating plunger 5 is installed in the two aligned holes. The locking pin at the bottom of the rotating plunger 5 can be inserted between the two holes, thus achieving a certain positioning and locking effect. This prevents the conical part 7 from dislodging from the conical groove 2, providing a good fastening and locking effect and improving the structural connection strength. For specific details, please refer to the attached instruction manual. Figure 5 As shown, the two products can be quickly locked together using the above method.

[0038] This utility model uses the cooperation between the conical structures to ensure a tight fit between the conical surfaces. This connection structure has no frame and will not cause shaking, effectively improving stability. It can be positioned and attracted by a strong magnet, so that the conical part 7 and the locking shell 1 can be firmly attracted together.

[0039] Meanwhile, the rotating plunger 5 can lock the structure, which solves the problem of insufficient magnetic attraction in a limited space, improves the connection strength, and the plunger locking combined with the strong attraction of the magnet can meet the needs of both large and small forces in actual use, thus improving applicability.

[0040] Furthermore, this utility model provides directional limiting protrusions and grooves on the conical groove 2 and the conical part 7. Through the cooperation of the protrusions and grooves, the problem of mutual rotation between the locking shell 1 and the conical part 7 can be effectively prevented, and it has a good limiting effect.

[0041] In summary, the locking structure of this utility model, through magnetic attraction and rotating plunger structure, realizes the fastening and connection between two structural components or products. At the same time, the insert-type hidden locking connection can effectively solve the problem that traditional locking devices are unsuitable and cannot be connected when there is no axial operating space. This effectively improves the applicability of the locking structure, reduces usage limitations, and improves the performance. Furthermore, through the use of conical surfaces, a frameless fit connection between two structural components can be achieved, preventing wobbling and effectively improving stability. The protrusions and grooves on the conical surfaces achieve structural orientation, preventing mutual rotation between the connecting parts.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
