Description

Technical Field

[0001] The utility model relates to the technical field of locking mechanisms, in particular to a quick locking mechanism. Background Art

[0002] At production or equipment installation sites, structural components often need to be quickly installed. When locking with bolts, each bolt needs to be inserted and tightened, which is not very convenient for subsequent disassembly. Therefore, a quick locking mechanism is needed to install and secure the structural components. The prior art has a locking structure that combines an inclined surface with a locking thread. This allows for quick locking between two workpieces to be locked. After locking, the structure self-locks to prevent loosening. However, its structure is still relatively complex, and its operation is still not convenient enough, requiring further improvement. Utility Model Content

[0020] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the embodiments described are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to a locking connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-Figure 2 As shown, an embodiment of the present invention provides a quick locking mechanism, comprising a locking seat 1, a locking shaft 2, and an adjustment seat 3. The locking seat 1 is provided with a center hole, into which the locking shaft 2 is inserted. A shoulder is provided near the first end of the locking shaft 2, and a spring 4 is provided between the shoulder and the locking seat 1, elastically connecting the locking shaft 2 and the locking seat 1. At least two limiting nuts are sleeved near the second end of the locking shaft 2, and the adjustment seat 3 is sleeved on the locking shaft 2 and located between the two limiting nuts. Preferably, the adjustment seat 3 and the locking shaft 2 are interference fit, so that the locking shaft 2 can rotate synchronously when the adjustment seat 3 is rotated.

[0024] In this embodiment, a first stop block 5 is provided at the first end of the locking shaft 2, and a second stop block 6 is provided on the locking seat 1. Both the first stop block 5 and the second stop block 6 are used for locking. For example, the first structural component and the second structural component are both provided with connecting holes. The first stop block 5 is disposed within the connecting hole of the first structural component, and the second stop block 6 is disposed within the connecting hole of the second structural component. The locking shaft 2 then moves relative to the locking seat 1 to bring the first stop block 5 and the second stop block 6 closer together, thereby securing the first structural component to the second structural component. During this process, the spring 4 is compressed. When quick disassembly is required, the locking shaft 2 is simply released. Under the action of the spring, the first stop block 5 and the second stop block 6 move away from each other, thereby enabling the first structural component to be removed relative to the second structural component.

[0025] In this embodiment, the end of the adjustment seat 3 opposite to the locking seat 1 is provided with an adjustment surface that is annular as a whole, and the adjustment surface is composed of a spiral surface 7 and a plane 8. The first end of the spiral surface 7 is connected to the second end of the plane 8 by a step transition, with a height difference, and the second end of the spiral surface 7 is smoothly connected to the first end of the plane 8. Correspondingly, the locking seat 1 is provided with a connecting pin 9, which maintains contact with the adjustment surface. When the connecting pin 9 contacts the first end of the spiral surface 7, the distance between the adjustment seat 3 and the locking seat 1 is the shortest, that is, the distance between the first limit block 5 and the second limit block 6 is the farthest, and the state is unlocked at this time. When the adjustment seat 3 is rotated so that the connecting pin 9 gradually contacts the second end of the spiral surface 7 and transitions to the first end of the plane, the distance between the adjustment seat 3 and the locking seat 1 increases, that is, the distance between the first limit block 5 and the second limit block 6 decreases, and the state is gradually switched to the locked state. Under the action of the plane and the spring 4, the adjustment seat 3 can maintain its position. When unlocking is required, just continue to rotate the adjustment seat 3 so that the connecting pin 9 moves to the second end of the plane and crosses the step. The spring 4 releases its elastic energy to make the adjustment seat 3 quickly approach the locking seat 1, thereby switching to the unlocked state again.

[0026] Therefore, when switching between the locked and unlocked states, one only needs to rotate the adjustment base 3, which is more convenient than twisting a bolt. As a preferred embodiment, the present embodiment further provides a handle 10 on the adjustment base 3. When rotating the adjustment base 3, one only needs to hold the handle 10, further improving the convenience of operation.

[0027] At the same time Figure 3 As shown, as a preferred embodiment, in this embodiment, a connecting block 11 is provided on the first structural component, and the connecting block 11 is provided with a first connecting hole 12 and a second connecting hole 13. The first connecting hole 12 and the second connecting hole 13 are transitioned by a connecting groove 14. The size of the connecting groove 14 matches the size of the first end of the locking shaft 2, the size of the first connecting hole 12 matches the size of the first limiting block 5, and the second connecting hole 13 is provided with a countersunk surface, and the size is smaller than the first connecting hole 12. Therefore, when installing the second structural component, the first connecting hole of the connecting block 11 can be inserted into the first end of the locking shaft 2 first, and then the connecting block 11 can be lowered to allow the first end of the locking shaft 2 to enter the second connecting hole 13 from the connecting groove 14. The adjusting seat 3 is rotated to move the locking shaft 2 so that the first limiting block 5 enters the first connecting hole 12 and locks it. The above process is reversed during disassembly and will not be repeated here.

[0028] Therefore, the quick locking mechanism provided in this embodiment, through the arrangement of the locking seat 1, the locking shaft 2, the adjustment seat 3, etc., can make the locking and unlocking of structural components more convenient, thereby improving the installation, disassembly and maintenance efficiency of the structure or equipment.

[0029] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
