Description

Technical Field

[0001] The utility model relates to the technical field of opening and closing mechanisms, in particular to a locking mechanism that can be opened within the range of 0° - 180°. Background Art

[0002] In the current technical field, structures involving opening and closing actions, such as the opening and closing design of boxes, mostly have certain limitations. After these structures are opened, they can often only be fixed at specific angles and cannot meet the requirements of multi-angle opening and locking, thus restricting the flexibility and convenience of operation.

[0003] Specifically, the existing box opening and closing structures usually use hinges or similar connecting parts to achieve the opening and closing functions. When these connecting parts are designed and manufactured, they can often only provide a fixed number of opening angles or can only achieve two states of fully open and fully closed. This means that during use, users cannot adjust the opening angle of the box cover according to actual needs, thus unable to achieve the best practical effect.

[0004] Based on this, in order to achieve the purpose of arbitrarily adjusting and fixing such opening and closing structures, we propose a locking mechanism that can be opened within the range of 0° - 180°. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages in the existing technology that it can often only be fixed at specific angles and cannot meet the requirements of multi-angle opening and locking, and to propose a locking mechanism that can be opened within the range of 0° - 180°.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Design a locking mechanism that can be opened within the range of 0° - 180°, including a movable body and a support body hinged at the end. On at least one side of the support body parallel to the rotation direction of the movable body, a sliding position is opened. A locking component is slidably connected in the sliding position. Fitting parts for guiding the locking component are arranged on the upper and lower sides of the sliding position. The outer side of the locking component is rotatably connected to a connecting rod, and the other end of the connecting rod is rotatably connected to the movable body.

[0008] Further, the locking component includes a magnetizable seat. A rotation hole is opened in the middle of the magnetizable seat. Two shielding bodies extending into the rotation hole are respectively embedded in the top and bottom of the magnetizable seat. A magnet is rotatably connected to the inner side of the rotation hole. One end of the magnet is fixed with a rotating shaft extending to the outside of the magnetizable seat.

[0009] Further, a cover plate is connected to the front side of the magnetizable seat through a fastener, and the cover plate is provided with a through hole for the rotation shaft to pass through.

[0010] Further, a screw rod is installed on the side surface of the movable body. Both ends of the connecting rod are respectively inserted and rotatably connected with the rotation shaft and the screw rod. A snap spring is clamped outside the rotation shaft, and the snap spring stops outside the connecting rod.

[0011] Further, the adapter is a metal guide rail, and sliding grooves adapted to the metal guide rail are respectively provided on the upper and lower sides of the magnetizable seat.

[0012] A locking mechanism that can be opened within the range of 0° - 180° proposed by the present utility model has the beneficial effects that: according to the principle of the magnetic switch in the present utility model, when the magnet does not conduct magnetism outward, the magnetizable seat can move freely at this time. By changing the position of the magnetizable seat, the movable body is driven to rotate. When reaching a predetermined angle, the magnet is rotated to make it conduct magnetism outward, and the position of the magnetizable seat is fixed with the cooperation of the adapter, so as to fix the unfolding angle of the movable body. It can control the movable body to be arbitrarily opened or locked within the range of 0° to 180°. The operation is simple and convenient. This locking structure can also be applied to fields that need to be stably opened or locked within a certain range, such as box lids, doors, windows, etc., and has strong applicability.

Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Refer to Figures 1-3This is an embodiment of the present utility model, which discloses a locking mechanism that can be opened within the range of 0° - 180°. Specifically, in this embodiment, a box is taken as an example. Of course, this structure can also be applied to some fields where products need to be stably opened or locked within a certain range, such as box lids, doors, windows, etc. The locking mechanism includes a movable body 1 and a support body 2 that are hinged at the ends. Of course, those skilled in the art know that in this embodiment, the movable body 1 can be arranged on the box cover, and the support body 2 can be arranged as the box body. The hinging method is a conventional technical means for those skilled in the art and will not be elaborated here too much;

[0019] Specifically, on at least one side surface of the support body 2 parallel to the rotation direction of the movable body 1, a sliding position 21 is opened. A locking component 3 is slidably connected in the sliding position 21. Fitting parts 22 for guiding the locking component 3 are arranged on the upper and lower sides of the sliding position 21. The outer side of the locking component 3 is rotatably connected to a connecting rod 4, and the other end of the connecting rod 4 is rotatably connected to the movable body 1.

[0020] During specific operation, the locking component 3 moves. Through the cooperation of the connecting rod 4, the movable body 1 can be supported and driven to rotate. When a predetermined angle is reached, the locking component 3 and the fitting part 22 are locked to fix the unfolded angle, so as to achieve the purpose of opening and locking within the range of 0° - 180°.

[0021] In some embodiments, the locking component 3 in the present utility model includes a magnetizable seat 31. A rotation hole 32 is opened in the middle of the magnetizable seat 31. Two shielding bodies 33 extending into the rotation hole 32 are respectively embedded on the top and bottom of the magnetizable seat 31. A magnet 34 is rotatably connected to the inner side of the rotation hole 32. One end of the magnet 34 is fixed with a rotating shaft 35 extending to the outside of the magnetizable seat 31.

[0022] Specifically, in this embodiment, the magnetizable seat 31 is made of iron, and the shielding body 33 is made of brass. It should be specifically noted that the two ends of the magnet 34 are respectively set as the south pole and the north pole. When the south and north poles of the magnet 34 rotate to face the brass at both ends respectively, since brass is non-magnetic, the magnetic lines of force of the magnet 34 enter from the north pole and exit from the south pole. Under the separation of the brass, all the magnetic lines of force are arranged inside the magnetizable seat 31, so there will be no magnetic attraction effect on the outside. On the contrary, when the magnet rotates to a perpendicular state with the two brass, the magnetic lines of force will pass through the outside of the magnetizable seat 31 to achieve the magnetic attraction effect.

[0023] On the basis of the above embodiments, in order to prevent the magnet 34 from falling out of the inside of the rotation hole 32, in this embodiment, a cover plate 36 is further connected to the front side of the magnetizable seat 31 through a fastener. The cover plate 36 is provided with a through hole for the rotation shaft 35 to pass through. Preferably, in this embodiment, the fastener is set as a bolt, and four of its matrix parts, that is, the cover plate 36 is fastened to the outside of the magnetizable seat 31 by bolts to realize the stop limit of the magnet 34.

[0024] Furthermore, in this embodiment, a screw rod 11 is installed on the side surface of the movable body 1. Both ends of the connecting rod 4 are respectively passed through and rotated with the rotation shaft 35 and the screw rod 11. Among them, a snap spring 37 is clamped on the outside of the rotation shaft 35. The snap spring 37 stops on the outside of the connecting rod 4. The design of the snap spring 37 is convenient for the assembly and disassembly of the connecting rod 4. Of course, those skilled in the art know that a ring groove should be opened on the outside of the rotation shaft 35 and the screw rod 11 for placing the snap spring 37.

[0025] In some embodiments, the adapter 22 in the present invention is a metal guide rail. Sliding grooves 5 adapted to the metal guide rail are opened on both the upper and lower sides of the magnetizable seat 31. It should be noted that the sliding position 21 in this embodiment is a groove structure. As described above, when the rotation shaft 35 rotates, the magnet 34 generates a magnetic attraction force outward. At this time, it can be magnetically fixed to the metal guide rail to complete the position fixation of the current magnetizable seat 31, so as to lock and fix the unfolding angle of the movable body 1.

[0026] In summary, the principle of the magnetic switch in the present invention is that when the magnet 34 conducts magnetism outward, the magnetizable seat 31 can move freely at this time. By changing the position of the magnetizable seat 31, the movable body 1 is driven to rotate. When reaching a predetermined angle, the magnet 34 is rotated to conduct magnetism outward, and the position of the magnetizable seat 31 is fixed under the cooperation of the adapter 22 to realize the fixation of the unfolding angle of the movable body 1. The movable body 1 can be arbitrarily opened or locked within the range of 0° to 180°. The operation is simple and convenient. This locking structure can also be applied to fields that need to be stably opened or locked within a certain range, such as box lids, doors, windows, etc., and has strong applicability.

[0027] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
