Description

Technical Field

[0001] The present invention relates to the field of machinery, and in particular to an easily disassembled double-bolt locking mechanism. Background Art

[0002] In order to improve the firmness and stability of the connection, many parts are now connected and installed with two bolts. Currently, nuts are mainly used to lock the two bolts. However, this locking method of using nuts to lock the two bolts separately is time-consuming and labor-intensive. On the other hand, the tightening torque of the two bolts cannot be balanced, and the gap between the two connecting parts after locking cannot be effectively guaranteed. The connection accuracy or installation accuracy is difficult to guarantee. In addition, the locking force of the nut is limited, and the nut is easy to fall off.

[0003] Therefore, in order to achieve a secure locking of the two bolts with less effort, it is necessary to design a double-bolt locking mechanism that is easy to disassemble and assemble. Summary of the Invention

[0004] In view of this, the present invention provides an easily detachable double-bolt locking mechanism that can securely lock two bolts very simply.

[0005] The easily disassembled double-bolt locking mechanism provided by the present invention comprises a mounting sleeve and a locking assembly rotatably engaged with the mounting sleeve. The mounting sleeve is provided with two bolt holes axially disposed therein for mounting bolts. By rotating the locking assembly, two bolts installed in the mounting sleeve can be simultaneously circumferentially locked. By simultaneously installing the two bolts on the mounting sleeve and providing a rotatable locking assembly to simultaneously lock the two bolts, the locking torque applied to the two bolts can be effectively balanced, ensuring high connection and installation accuracy. Furthermore, the locking method is very simple and labor-saving. Furthermore, the circumferential locking state of the two bolts can be released by rotating the locking assembly to a certain position. Therefore, the easily disassembled double-bolt locking mechanism of the present invention can achieve not only rapid and uniform locking, but also rapid loosening.

[0006] Furthermore, the locking assembly includes a locking block rotatably mounted within the mounting sleeve, a rotary handle for axially pressing the locking block within the mounting sleeve and driving the locking block for rotation, and a connector for connecting the mounting sleeve and the rotary handle. The connector includes a connecting rod and a limit plate disposed at one end of the connecting rod. The locking block is externally mounted on the connecting rod, and the other end of the connecting rod passes axially through the mounting sleeve and is detachably connected to the rotary handle, specifically a threaded connection. The connecting rod is provided with an external thread, and the rotary handle is provided with an internal thread. A cavity for mounting the locking block is defined within the mounting sleeve. Preferably, the cavity has a circular cross-section, and preferably, the axis of the bolt hole is located on the circumference of a circle formed by the cavity wall. The locking block can be rotatably mounted within the cavity through the cooperation of the connector and the rotary handle. The mounting sleeve is provided with a connecting rod through-hole for the connecting rod to pass through. In order to better balance the locking torque, the connecting rod, locking block and mounting sleeve are arranged coaxially, the axes of the two bolt holes on the mounting sleeve are arranged coplanar with the axis of the locking block, and the axes of the two bolt holes are arranged symmetrically about the axis of the locking block.

[0007] Furthermore, the locking block includes a locking block body and multiple elastic blocks arranged circumferentially around the locking block body for circumferentially locking the bolts. The locking block can have various configurations, such as a waist-shaped or elliptical cross-section. The locking block is preferably symmetrical, with the distance between the ends of the two elastic blocks used to lock the two bolts greater than the shortest distance between the outer diameters of the two bolts, ensuring that the locking block can achieve circumferential locking of the bolts after rotation.

[0008] Furthermore, the locking block body and the elastic block are formed in one piece, and the strength of the one-piece structure is higher.

[0009] Furthermore, it also includes a preload assembly, which includes a guide rod, a pressure plate and a spring. The rotary handle is provided with an installation cavity along the axial direction. The pressure plate is slidably arranged in the installation cavity along the axial direction. The spring is arranged between the bottom of the installation cavity and the pressure plate. One end of the guide rod is provided with a push plate, and the other end passes through the connecting piece along the axial direction and is detachably connected to the pressure plate, specifically a threaded connection. The guide rod is provided with an external thread, and the pressure plate is provided with an internal thread. The spring is a compression spring. During the installation process of the locking mechanism, the spring is installed in a compressed state between the bottom of the installation cavity and the pressure plate. At this time, the spring will give an axial preload to the push plate and the connecting rod in contact with the push plate. The connecting rod is threadedly connected to the rotary handle. At this time, the rotary handle will also receive this axial preload. This axial preload will press the locking block downward, which has the effect of axially increasing the pressure on the locking block, thereby ensuring that the locking block can achieve a more secure locking of the bolt and avoid the occurrence of movement or jumping. If you need to turn the locking block, you only need to press it down slightly and use the push plate to push the pressure plate away from the end face of the connecting rod to further compress the spring. At this time, the spring will no longer have an axial pressure-increasing effect on the locking block, and the operator can easily turn the handle to drive the locking block to rotate.

[0010] Furthermore, the invention further comprises a locking sleeve, one end of which is detachably connected to the locking block and the other end of which is inserted into the rotating handle. The locking sleeve is disposed between the connecting rod and the rotating handle. Rotating the rotating handle drives the locking sleeve to rotate, thereby driving the locking block disposed at the lower end of the locking sleeve to rotate. To better achieve the rotation of the locking sleeve driven by the rotating handle, mutually cooperating positioning blocks and positioning holes can be provided on the rotating handle and the locking sleeve. The rotating handle and the locking sleeve can be threadedly connected. Alternatively, the contact surface between the rotating handle and the locking sleeve can be roughened to provide greater friction.

[0011] Furthermore, the elastic block is made of polyurethane, which has good elasticity.

[0012] The method of using the easily disassembled double-bolt locking mechanism of the present invention is as follows: when locking, the two bolts installed on the workpiece are respectively passed through the bolt holes on the mounting sleeve, and then the push plate on the guide rod is abutted against the workpiece, and then the locking block is driven to rotate by rotating the rotary handle, so that the circumferential elastic blocks of the locking block are rotated to contact the outer circumferential surfaces of the two bolts, and the two bolts can be circumferentially locked; when disassembling, the rotary handle is rotated to drive the locking block to rotate, so that the circumferential elastic blocks of the locking block are rotated to no longer contact the outer circumferential surfaces of the two bolts, and the circumferential locking state of the two bolts can be released, and loosening can be achieved.

[0013] The beneficial effects of the present invention are as follows: The easily removable dual-bolt locking mechanism provided by the present invention simultaneously secures the two bolts by simultaneously installing the two bolts on the mounting sleeve and disposing a rotatable, highly elastic locking block within the mounting sleeve. This effectively balances the tightening torque applied to the two bolts, ensuring high connection and installation accuracy. Furthermore, the locking method is simple and labor-saving, enabling rapid and uniform tightening and quick loosening. Furthermore, the provision of a preload assembly generates an axial preload, which acts as an axial pressure booster on the locking block, thereby ensuring a more secure locking of the bolts by the locking block.

[0020] Figure 1 is a cross-sectional view of the easily disassembled double-bolt locking mechanism of the present invention; Figure 2 It is a top view of the easily disassembled double-bolt locking mechanism of the present invention; Figure 3 Schematic diagram of the structure of the locking block 2 of the present invention; the left and right, up and down, inside and outside and other orientations or positional relationships in this embodiment are based on the orientations or positional relationships shown in the accompanying drawings; as shown in the figure:

[0021] The easily disassembled dual-bolt locking mechanism provided in this embodiment includes a mounting sleeve 1 and a locking assembly rotatably engaged with the mounting sleeve 1. The mounting sleeve 1 is provided with two bolt holes 10 along the axial direction for mounting bolts. By rotating the locking assembly, the two bolts installed in the mounting sleeve 1 can be simultaneously circumferentially locked. By simultaneously installing the two bolts on the mounting sleeve 1 and providing a rotatable locking assembly to simultaneously lock the two bolts, the locking torque of the two bolts can be effectively balanced, ensuring high connection and installation accuracy. The locking method is also very simple and labor-saving. At the same time, the circumferential locking state of the two bolts can be released by rotating the locking assembly to a certain position. Therefore, the easily disassembled dual-bolt locking mechanism of this embodiment can achieve not only rapid and uniform locking, but also rapid loosening.

[0022] In this embodiment, the locking assembly includes a locking block 2 rotatably mounted within a mounting sleeve 1, a rotary handle 4 for axially compressing the locking block 2 within the mounting sleeve 1 and driving the locking block 2 for rotation, and a connector for connecting the mounting sleeve 1 and the rotary handle 4. The connector includes a connecting rod 51 and a stop plate 52 disposed at one end of the connecting rod 51. The locking block 2 is externally mounted on the connecting rod 51. The other end of the connecting rod 51 axially passes through the mounting sleeve 1 and is detachably connected to the rotary handle 4, specifically, by a threaded connection. The connecting rod 51 is provided with an external thread, and the rotary handle 4 is provided with an internal thread. The mounting sleeve 1 defines a cavity for mounting the locking block 2. Preferably, the cavity has a circular cross-section, and preferably, the axis of the bolt hole 10 is located on the circumference of a circle formed by the cavity wall. The locking block 2 can be rotatably mounted within the cavity through the cooperation of the connector and the rotary handle 4. The mounting sleeve 1 is provided with a through hole for the connecting rod 51 for passing the connecting rod 51. In order to better balance the locking torque, the connecting rod 51, the locking block 2 and the mounting sleeve 1 are coaxially arranged, the axes of the two bolt holes 10 on the mounting sleeve 1 are coplanar with the axis of the locking block 2, and the axes of the two bolt holes 10 are symmetrically arranged about the axis of the locking block 2.

[0023] In this embodiment, the locking block 2 comprises a locking block body 21 and a plurality of elastic blocks 22 disposed circumferentially around the locking block body 21 for circumferentially locking the bolts. The locking block 2 can have various configurations, such as a waist-shaped or elliptical cross-section. The locking block 2 is preferably symmetrical, with the distance between the ends of the two elastic blocks 22 used to lock the two bolts being greater than the shortest distance between the outer diameters of the two bolts, ensuring that the locking block 2 can achieve circumferential locking of the bolts after rotation.

[0024] In this embodiment, the locking block body 21 and the elastic block 22 are integrally formed. The integral structure has higher strength.

[0025] In this embodiment, a preload assembly is also included, which includes a guide rod 6, a pressure plate 7 and a spring 8. The rotating handle 4 is provided with an installation cavity along the axial direction, and the pressure plate 7 is slidably arranged in the installation cavity along the axial direction. The spring 8 is arranged between the bottom of the installation cavity and the pressure plate 7. A push plate 9 is provided at one end of the guide rod 6, and the other end penetrates the connecting piece along the axial direction and is detachably connected to the pressure plate 7, specifically a threaded connection. The guide rod 6 is provided with an external thread, and the pressure plate 7 is provided with an internal thread. The spring 8 is a compression spring 8. During the installation of the locking mechanism, the spring 8 is installed in a compressed state between the bottom of the installation cavity and the pressure plate 7. At this time, the spring 8 will give an axial preload to the push plate 9 and the connecting rod 51 in contact with the push plate 9. The connecting rod 51 is threadedly connected to the rotating handle 4. At this time, the rotating handle 4 will also receive this axial preload. This axial preload will press the locking block 2 downward, exerting an axial pressure on the locking block 2, thereby ensuring that the locking block 2 can achieve a more secure locking of the bolt and avoid any movement or jumping. If it is necessary to rotate the locking block 2, it is only necessary to press it down slightly and use the push plate 9 to push the pressure plate 7 away from the end face of the connecting rod 51, so that the spring 8 is compressed in this embodiment. At this time, the spring 8 will no longer exert an axial pressure on the locking block 2, and the operator can easily turn the handle, thereby driving the locking block 2 to rotate.

[0026] This embodiment further includes a locking sleeve 3, one end of which is detachably connected to the locking block 2 and the other end of which is inserted into a rotating handle 4. The locking sleeve 3 is disposed between the connecting rod 51 and the rotating handle 4. Rotating the rotating handle 4 drives the locking sleeve 3 to rotate, thereby driving the locking block 2 disposed at the lower end of the locking sleeve 3 to rotate. To better achieve the rotation of the locking sleeve 3 by the rotating handle 4, mutually cooperating positioning blocks and positioning holes can be provided on the rotating handle 4 and the locking sleeve 3. The rotating handle 4 and the locking sleeve 3 can be threadedly connected, or the contact surface between the rotating handle 4 and the locking sleeve 3 can be roughened to provide greater friction.

[0027] In this embodiment, the elastic block 22 is made of polyurethane, which has good elasticity.

[0028] The method of using the easily disassembled double-bolt locking mechanism of this embodiment is as follows: when locking, the two bolts installed on the workpiece are respectively passed through the bolt holes 10 on the mounting sleeve 1, and then the push plate 9 on the guide rod 6 is abutted against the workpiece, and then the locking block 2 is driven to rotate by rotating the rotary handle 4, so that the circumferential elastic block 22 of the locking block 2 is rotated to contact the outer circumferential surfaces of the two bolts, and the two bolts can be circumferentially locked; when disassembling, the rotary handle 4 is rotated to drive the locking block 2 to rotate, so that the circumferential elastic block 22 of the locking block 2 is rotated to no longer contact the outer circumferential surfaces of the two bolts, and the circumferential locking state of the two bolts can be released, and loosening can be achieved.
