1 to 9 , an embodiment of the present application provides a locking sleeve, including:

Cylinder 1;

A rotating disk 2 is rotatably disposed on the cylinder 1;

A locking assembly, disposed on the cylinder 1 and connected to the assembly surface 22 of the rotating disk 2, the locking assembly comprising at least two locking members 3 spaced apart from each other; and

The connecting component includes an Archimedes spiral 21 track and a counter-rail 31 that matches the Archimedes spiral 21 track. The Archimedes spiral 21 track is formed on the assembly surface 22. The counter-rail 31 is formed on the connecting surface 32 of the locking member 3 and is used for being embedded and connected with the Archimedes spiral 21 track.

By rotating the rotating disk 2, the Archimedean spiral 21 on the rotating disk 2 will rotate synchronously, and under its action, the matching rail 31 will move synchronously, thereby driving the movement of the locking member 3 connected thereto. During the rotation of the rotating disk 2, each locking member 3 moves toward or away from each other, thereby adjusting the distance between each locking member 3. Each locking member 3 is used to be connected to a component to be locked. By adjusting the distance between each locking member 3, components to be locked of different models or structures can be adapted, so that components to be locked of different styles can be locked by the locking sleeve provided by the present application, thereby improving the wide applicability of the device, greatly reducing the cost of the device, and improving the work efficiency of production and preparation.

The number of locking members 3 is not limited in this application. Two locking members 3 can be provided, and the clamping or locking of the part to be locked can be achieved through the two locking members 3. Of course, three or more locking members 3 can also be provided, and the reliability of the connection between the locking assembly and the part to be locked can be improved by cooperating with different positions of the locking member with multiple locking members 3. Of course, the number of locking members 3 can also be selected according to the specific structural features of the part to be locked. For example, when the part to be locked that is used to cooperate with the locking assembly is a triangle, it is preferred that there are three locking members 3, and the three locking members 3 correspond to the three planes of the triangle of the part to be locked, so as to ensure stable locking.

Similarly, the structural style of the locking member 3 is not limited in this application, wherein the locking member 3 can be arranged in a V-shaped structure, and the two locking members 3 are arranged symmetrically to each other, so as to lock and fix the part to be locked. Of course, the locking member 3 can also be a plate-like structure, a style that matches the outer peripheral side of the part to be locked 3, or other structural styles, so as to achieve connection with the outer peripheral side of the part to be locked. At this time, the part to be locked can be a bolt with an external hexagonal structure, etc. Of course, the locking member 3 can also be arranged in a conical structure to be embedded in the part to be locked, for example, multiple locking members 3 cooperate with each other to achieve a cross structure with an adjustable distance. At this time, the part to be locked can be a screw with an embedded hole on the top. The cross structure connecting the locking members 3 is adjusted to a size distance that matches the screw, so that the screw can be matched and locked.

Specifically, a guide member 4 is also provided in the cylinder 1, and a plurality of guide tracks are provided on the guide member 4, each of the guide tracks is used to cooperate with each of the locking members 3, and the guide tracks are extended along the radial direction of the rotating disk 2; the moving direction of the locking members 3 is guided by the guide tracks to ensure that under the rotation of the rotating disk, each of the locking members 3 can stably move in a direction close to or away from each other to adjust the diagonal diameter between each of the locking members 3.

The guide rail is opened on the guide member 4 along the axial direction of the rotating disk 2, and the locking member 3 includes a first part 33, a second part 34 and a locking end 35 connected to each other, wherein the locking end 35 is used to cooperate with the component to be locked, the counter rail 31 is formed on the first part 33, and the second part 34 is used to cooperate with the guide rail, and the size of the first part 33 is larger than the cross-sectional size of the guide rail to ensure that the locking member 3 can be stably set on the guide member 4.

Optionally, the guide member 4 is detachably arranged on the cylinder 1, so when a part to be locked with a special shape needs to be adapted, the guide member 4 only needs to be removed from the cylinder 1, and it will be removed from the cylinder 1 with the locking member 3, and then a guide member 4 with a locking member 3 adapted to the part to be locked can be installed on the cylinder 1, which greatly reduces the cost of the device. The detachable connection between the guide member 4 and the cylinder 1 can be screwed or other matching methods.

1 to 9 , in some embodiments, at least a portion of the outer peripheral side of the rotating disk 2 protrudes from the barrel 1 , and a rotating tooth 23 is provided on the rotating disk 2 protruding from the barrel 1 ; the setting of the rotating tooth 23 facilitates the user to rotate the rotating disk 2 , thereby facilitating operation.

Optionally, a rotating opening is provided at a circumferentially corresponding position of the cylinder 1 and the rotating disk 2, and the outer peripheral side of the rotating disk 2 protrudes from the cylinder 1 through the rotating opening, and the rotating shifting teeth 23 are formed on the circumference of the rotating disk 2; by setting the outer peripheral side of the rotating disk 2 to protrude from the cylinder 1, the user can act on any part of the rotating disk 2 according to the environment or operating habits to make the rotating disk 2 rotate.

In some embodiments, a positioning assembly 5 is further provided in the cylinder 1, and the positioning assembly 5 includes a buckle 51 and a slot 52 that are embedded and matched. The side of the rotating disk 2 away from the assembly surface 22 is a positioning surface 24, and the slot 52 is arranged on the positioning surface 24, and multiple buckles 51 are arranged at intervals in the circumference of the rotating disk 2. The buckle 51 is movably arranged on the cylinder 1 along its embedding direction; after the rotating disk 2 rotates to rotate the positions of multiple locking members 3 to match the parts to be locked, the rotating disk 2 is fixed by the positioning assembly 5 to avoid damage to the parts to be locked caused by the continued rotation of the rotating disk 2, or the rotating disk 2 is accidentally rotated in the opposite direction to cause improper assembly between the locking member 3 and the parts to be locked. Therefore, by mutually embedding the buckle 51 and the slot 52, by clamping the buckle 51 in the slot 52, the rotating disk 2 can be fixed relative to the cylinder 1. At this time, the user continues to swing the rotating disk 2, and the rotating disk 2 will not change its position, thereby ensuring the reliability of the position of the locking member 3.

The positioning surface 24 is provided with a plurality of positioning teeth 25 at intervals along the circumference of the rotating disk 2, and the clamping grooves 52 are formed between adjacent positioning teeth 25. Through the arrangement of the positioning teeth 25, a plurality of equidistant and evenly distributed clamping grooves 52 can be formed on the rotating disk 2 to ensure that the rotating disk 2 can cooperate with the buckle 51 after rotating to any position, thereby fixing the locking member 3.

The slot 52 is opened along the axis of the rotating disk 2, so the buckle 51 moves back and forth along the axis of the rotating disk 2, thereby realizing the embedded fit or the cancellation of fit with the slot 52. Specifically, the cylinder 1 may be provided with a movable slot, which is opened along the axis of the rotating disk 2, and the buckle 51 is movably arranged in the movable slot.

Of course, the movement of the buckle 51 can be achieved by driving a driving component, for example, an electric push rod or a cylinder is provided in the cylinder 1, and its movable end is connected to the buckle 51 to drive the movement of the buckle 51. In addition, the buckle 51 can also be moved by other means.

Referring to Figures 1 to 9, specifically, the locking sleeve also includes a limit card cover 6 rotatably arranged in the cylinder body 1, and a plurality of guide through holes 61 cooperating with the buckle 51 are opened on the limit card cover 6. The limit card cover 6 rotates to drive the buckle 51 to move in the direction away from the slot 52 under the guiding action of the guide through holes 61; a reset member 7 is arranged in the cylinder body 1, and the reset member 7 is connected to the buckle 51 to drive the buckle 51 to move in the direction close to the slot 52; a guide portion is formed on the inner wall of the guide through hole 61. During the rotation of the limit card cover 6 and under the action of the guide portion, the buckle 51 will move in the direction away from the rotating disk 2, thereby compressing the reset member 7 and separating the buckle 51 from the slot 52. When the guide through hole 61 of the limit card cover 6 is aligned with the buckle 51, the buckle 51 will move toward the direction close to the slot 52 under the restoring force of the restoring member 7, so as to be embedded in the slot 52 and fix the rotating disk 2. Optionally, the restoring member 7 can be a spring or the like.

In some embodiments, annular tracks 62 are formed on the opposite sides of the rotating disk 2 and the limiting chuck 6, and the two annular tracks 62 are arranged opposite to each other. The two annular tracks 62 are assembled with each other to form a complete and closed channel, and a plurality of balls 8 are arranged at intervals in the channel to ensure the stable rotation of the rotating disk 2 and the limiting chuck.

In some embodiments, the barrel 1 is provided with a connection opening 101, and the side wall of the connection opening 101 is provided with at least one connection portion 102, wherein the connection opening 101 is used to connect with a force-applying component, and the force-applying component acts on the barrel 1 to realize the rotation of the barrel 1 to lock the component to be locked. The connection portion 102 is used to cooperate with the force-applying portion of the force-applying component to ensure the reliability of the connection between the force-applying component and the barrel 1.

1 to 9 , an embodiment of the present application further provides a locking device, comprising a wrench 9 and the locking sleeve described in the aforementioned embodiment, wherein the wrench 9 is connected to the locking sleeve to drive the movement of the locking sleeve.

Among them, the wrench 9 is a force-applying component used to connect with the cylinder 1. The wrench 9 is provided with a force-applying portion, which includes a pressure rod 10 movably arranged on the wrench 9, and a groove 11 is opened on the pressure rod 10. The wrench 9 is also provided with a positioning steel column 12, which is movably arranged, and a reset spring 13 is arranged between the bottom of the pressure rod 10 and the wrench 9; therefore, when the pressure rod 10 is pressed downward, the positioning steel column 12 will enter the groove 11 on the pressure rod 10 under the action of the pressure rod 10, so that the positioning steel column 12 is located inside the wrench 9, and the wrench 9 can be matched with the connecting opening 101 at this time. After the wrench 9 enters the cylinder 1, the pressure rod 10 is released, and the positioning steel column 12 is squeezed out of the groove 11 under the action of the reset spring 13, protruding the wrench 9, and matching with the connecting portion 102 on the connecting opening 101, so as to be connected.
