Description

Technical Field

[0001] The invention relates to the field of detachable rotating shaft hinges, and in particular to a detachable rotating shaft hinge. Background Art

[0002] Hinge generally refers to hinges, which are mechanical devices designed to connect two solid objects and allow relative rotation between these objects. The structure of the hinge can contain movable components or be made of materials that can be folded. In daily life and furniture manufacturing, hinges are particularly common in the installation of cabinets. Depending on the material, hinges are mainly divided into two categories: stainless steel hinges and iron hinges. In order to improve the user experience, people have also developed hydraulic hinges (also known as damping hinges). The characteristic of this hinge is that when the cabinet door is closed, it can provide a buffering function, effectively reducing the noise generated when the cabinet door collides with the cabinet body, thus bringing a quieter and more comfortable experience to users.

[0003] The hinges currently used, especially those used to connect large objects, mainly rely on screws to achieve a detachable connection. However, due to the frequent rotation of the hinge leaves, this often causes the screws to gradually loosen. Once the screws are loose, it will affect the smooth rotation of the connected objects. If this situation is not discovered and handled in time, it may lead to serious consequences.

[0004] In order to solve the above problems, a detachable rotating shaft hinge is proposed in the present application. Summary of the invention

[0005] 1. Purpose of the invention In order to solve the technical problems existing in the background technology, the present invention proposes a detachable rotating shaft hinge. The present invention can increase the pressing force between the second connecting piece and the connected object by installing an auxiliary pressing mechanism. In addition, when the connected object and the second connecting piece are loose, the auxiliary pressing mechanism can respond and promptly remind the user to pay attention to the loose condition.

[0006] (II) Technical solution In order to solve the above problems, the present invention provides a detachable rotating shaft hinge, comprising a rotating shaft body and a connecting piece 1 connected to the rotating shaft body, wherein a connecting piece 2 is rotatably connected to the rotating shaft body, and the connecting piece 2 is staggered with the connecting piece 1; A receiving groove is formed on one side of the connecting piece 2, and an entrance is formed on the side of the connecting piece 2. An auxiliary pressing mechanism for pressing against the mounting surface is provided inside the receiving groove, and the auxiliary pressing mechanism has a first state and a second state; In the first state, the auxiliary pressing mechanism is unresponsive; In the second state, the auxiliary clamping mechanism expands to assist in expansion and reduce shaking.

[0007] Preferably, the auxiliary clamping mechanism includes a clamping bolt, a movable plate, a clamping plate and a spring. The clamping plate and the movable plate are parallel to each other and are respectively slidably connected to the accommodating groove. The clamping plate and the movable plate are connected by a spring. The clamping bolt is threadedly sleeved on the connecting plate 2, and the insertion end of the clamping bolt is pressed toward the movable plate.

[0008] Preferably, the insertion end of the clamping bolt is rotatably sleeved with a ball that is rollingly connected to the movable plate.

[0009] Preferably, an X-cross rod is provided between the clamping plate and the movable plate, and the two ends of the X-cross rod close to the clamping plate are connected to the clamping plate through a rotating shaft and a connecting block, and the other two ends of the clamping plate are rotatably connected to a rotating wheel through a rotating shaft.

[0010] Preferably, an annular groove is provided in the middle of the rotating wheel, and the annular groove is connected to a ball via a connecting rope.

[0011] Preferably, a torsion spring is movably sleeved on the outer periphery of the rotating shaft on the X-cross rod, and the end of the torsion spring is fixedly connected to the X-cross rod.

[0012] Preferably, a rack is embedded on one side of the movable plate facing the pressing plate, and a tooth groove matched with the rack is formed on one side of the outer circumference of the rotating wheel.

[0013] Preferably, both the connecting piece 1 and the connecting piece 2 are provided with mounting holes for screws to pass through.

[0014] The above technical solution of the present invention has the following beneficial technical effects: Connecting piece 2 is responsible for connecting the object that needs to rotate, while connecting piece 1 is connected to the stationary object. During the specific connection process, connecting piece 2 is placed in the placement slot of the rotating object and fixed with screws. At this time, the clamping plate is facing the placement slot of the rotating object. When the clamping bolt is rotated, it will drive the moving plate to compress the spring, thereby storing energy. The compressed spring will react to the clamping plate, causing it to exert pressure on the connection of the rotating object, thereby increasing the tension after installation and reducing the occurrence of looseness.

[0015] If the connection between the second connecting piece and the rotating object is loose, the elastic force of the spring will push the clamping plate out of the receiving groove, reducing or eliminating the existing gap, playing an auxiliary fixing role, and avoiding the inconvenience of movement caused by the gap. At the same time, as the rotating object rotates, if the connection is loose, the clamping plate will continue to move in or out of the receiving groove. During this process, the X-cross rod will rotate with the rotating shaft on it as the center, thereby driving the rotating wheel to roll along the length direction of the rack. The rotation of the rotating wheel will drive the connecting rope and the ball to rotate, and the ball will then hit the moving plate and respond, thereby reminding the user that there is an abnormal loose phenomenon.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0023] like Figure 1-5 As shown, a detachable rotating shaft hinge proposed by the present invention comprises a rotating shaft body 1 and a connecting piece 1 2 connected to the rotating shaft body 1, the connecting piece 2 3 is connected to an object to be rotated, and the connecting piece 1 2 is connected to a stationary object, the connecting piece 2 3 is placed in a placement groove of the rotating object and connected by screws, and mounting holes for screws to pass through are provided on the connecting piece 1 2 and the connecting piece 2 3, and the number of mounting holes is multiple to increase the tightness of the connecting piece 1 2 and the connecting piece 2 3 after installation, and the rotating shaft body 1 is rotatably connected with the connecting piece 2 3, and the connecting piece 2 3 is staggered with the connecting piece 1 2; A receiving groove 31 is formed on one side of the connecting piece 2 3, and the receiving groove 31 forms an entry toward one side of the connecting piece 2 3. An auxiliary pressing mechanism 4 for pressing against the mounting surface is provided inside the receiving groove 31. The auxiliary pressing mechanism 4 is provided in multiple groups, and the auxiliary pressing mechanism 4 has a first state and a second state. In the first state, the auxiliary clamping mechanism 4 has no response; In the second state, the auxiliary clamping mechanism 4 expands to assist in the expansion and reduce the shaking.

[0024] In an optional embodiment, the auxiliary clamping mechanism 4 includes a clamping bolt 41, a movable plate 42, a clamping plate 43 and a spring 44. The clamping plate 43 and the movable plate 42 are parallel to each other and are respectively slidably connected to the accommodating groove 31. The clamping plate 43 and the movable plate 42 are connected by a spring 44. There are multiple springs 44, which are evenly divided into two groups, and the two groups of springs 44 are symmetrically arranged. The clamping bolt 41 is threadedly sleeved on the connecting plate 2 3, and the insertion end of the clamping bolt 41 presses against the movable plate 42. After the clamping bolt 41 is fully extended into the accommodating groove 31, the clamping bolt 41 can no longer rotate. At this time, there is a gap between the movable plate 42 and the side wall of the accommodating groove 31 away from the entrance.

[0025] It should be noted that the tightening bolt 41 is rotated, and the tightening bolt 41 drives the moving plate 42 (the moving plate 42 is a metal plate that responds when struck) to compress the spring 44 to store energy. The spring 44 is compressed, and acts on the connection between the tightening plate 43 and the rotating object, increasing the tension after installation, thereby reducing the loosening phenomenon. When the connection between the connecting piece 2 3 and the rotating object is loose, the spring 44 drives the tightening plate 43 to move out of the receiving groove 31, reducing the existing gap, thereby playing an auxiliary role in use, thereby reducing the inconvenience of movement caused by the gap.

[0026] Furthermore, the insertion end of the clamping bolt 41 is rotatably sleeved with a ball that is rollingly connected to the movable plate 42. In order to increase the smoothness when the clamping bolt 41 presses against the movable plate 42, the ball is located at the insertion end of the clamping bolt 41, thereby increasing the smoothness of the clamping bolt 41 when rotating.

[0027] In an optional embodiment, an X-cross rod 45 (the X-cross rod 45 is composed of two rod bodies) is provided between the clamping plate 43 and the movable plate 42. The two ends of the X-cross rod 45 close to the clamping plate 43 are connected to the clamping plate 43 through a rotating shaft and a connecting block 46. One connecting block 46 is fixedly connected to the clamping plate 43, and the other connecting block 46 is slidably connected to the clamping plate 43. When the two rod bodies of the X-cross rod 45 rotate, one connecting block 46 can slide along the clamping plate 43 so that the rod body can rotate. The two connecting blocks 46 are symmetrically arranged, and the other two ends of the clamping plate 43 are rotatably connected with a rotating wheel 47 through a rotating shaft.

[0028] Furthermore, in order to respond and accommodate, an annular groove 471 is opened in the middle of the rotating wheel 47. Under the action of the annular groove 471, it plays a role of accommodating and storing. The annular groove 471 is connected to the ball 49 through the connecting rope 48. When the connecting ball 49 rotates, it can be rotated out of the annular groove 471 to collide with the movable plate 42 for response.

[0029] The connecting ball 49 is a bell so that it responds when struck.

[0030] In order to increase the restoring effect of the X-cross rod 45 when it rotates, a torsion spring is movably sleeved on the outer periphery of the rotating shaft of the X-cross rod 45, and the end of the torsion spring is fixedly connected to the X-cross rod 45. The two ends of the torsion spring are respectively fixedly connected to the adjacent X-cross rod 45, so that after the clamping plate 43 and the movable plate 42 are separated, the torsion spring can restore to drive the X-cross rod 45 to rotate.

[0031] In an optional embodiment, in order to increase the stability of the rotating wheel 47 during rotation, a rack 410 is embedded on the side of the movable plate 42 facing the clamping plate 43, and a tooth groove adapted to the rack 410 is provided on one side of the outer periphery of the rotating wheel 47. The tooth groove is provided in a circle on the outer periphery of the rotating wheel 47, so that when the rotating wheel 47 rotates, it adapts to the rack 410, and then when it rolls along the length direction of the rack 410, its rotation stability is increased.

[0032] Since the connecting ball 49 is located inside the annular groove 47 and the tooth groove is located on one side of the outer circumference of the rotating wheel 47, when the connecting ball 49 rotates, it can only hit the moving plate 42 to respond.

[0033] In the present invention, the connecting piece 2 3 is responsible for connecting the object that needs to be rotated, while the connecting piece 1 2 is connected to the stationary object. In the specific connection process, the connecting piece 2 3 is placed in the placement groove of the rotating object and fixed by screws. At this time, the clamping plate 43 is facing the placement groove of the rotating object. When the clamping bolt 41 is rotated, it will drive the moving plate 42 to compress the spring 44, thereby storing energy. The compressed spring 44 will react to the clamping plate 43, causing it to apply pressure to the connection of the rotating object, thereby improving the tension after installation and reducing the occurrence of looseness.

[0034] If the connection between the connecting piece 23 and the rotating object is loose, the elastic force of the spring 44 will push the clamping plate 43 out of the receiving groove 31, reduce or eliminate the existing gap, play an auxiliary fixing role, and avoid the inconvenience of movement caused by the gap. At the same time, as the rotating object rotates, if the connection is loose, the clamping plate 43 will continue to move in or out of the receiving groove 31. During this process, the X-cross rod 45 will rotate with the rotating shaft on it as the center, thereby driving the rotating wheel 47 to roll along the length direction of the rack 410. The rotation of the rotating wheel 47 will drive the connecting rope 48 and the ball 49 to rotate, and the ball 49 will then hit the moving plate 42 and respond, thereby reminding the user that there is an abnormal loose phenomenon.

[0035] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
