[0002] In a mechanical motion system, after the motion mechanism reaches a predetermined position, if it is necessary to keep the motion mechanism stationary for a certain period of time to prevent erroneous movement, the motion mechanism must be locked; however, in many cases only one-way locking is required to achieve the desired purpose.

The reducer is connected to the motor up and down, and the reducer is placed on the top. The transmission shaft key of the screw shaft is connected to the gear, and is arranged at the output end of the reducer through a bearing. The motor and the reducer transmit torque through the gear meshing between the shafts. The motor drives the screw shaft to move the sliding shaft through the reducer, and the fixed locking support is locked and unlocked relative to the transmission locking support through the action of the rocker rod.

[0055] DETAILED DESCRIPTION

[0056] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0057] The present invention provides a controllable movable connector, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a sleeve 1, a first stop and distance nut 2, a steel ball 6, a connecting piece 8, a second stop and distance nut 9, a sleeve rod 10, a first retaining ring 31 and a second retaining ring 32. A first mounting mechanism is provided at one end of the sleeve 1, and a sleeve internal thread is provided inside the other end of the sleeve 1. The connecting piece 8 is a tubular structure. A connecting piece external thread and a connecting piece first internal thread are provided on the outside and inside of one end of the connecting piece 8, respectively. A connecting piece second internal thread is provided on the inside of the other end of the connecting piece 8. The connecting piece 8 is threadedly connected with the sleeve internal thread of the sleeve 1 through the connecting piece external thread; the first stop and distance nut 2 and the second stop and distance nut 9 are both annular structures. The first stop and distance nut 2 and the second stop and distance nut 9 are respectively provided with a first stop and distance nut external thread and a second stop and distance nut external thread. The first stop and distance nut 2 is mounted on the sleeve internal thread of the connecting piece 8 through the first stop and distance nut external thread. The second fixing nut is matched with the external thread of the second stop and spacing nut and is installed on the second internal thread of the connector 8. One end of the sleeve rod 10 passes through the second stop and spacing nut 9 and the first stop and spacing nut 2 in sequence and extends to the interior of the sleeve 1. The other end of the sleeve rod 10 is provided with a second mounting mechanism, wherein the first mounting mechanism and the second mounting mechanism are used to install equipment that needs to be removably connected, including installing the equipment that needs to be removably connected on the first mounting mechanism and fixing the second mounting mechanism; or installing the equipment that needs to be removably connected on the second mounting mechanism and fixing the first mounting mechanism; or installing the equipment that needs to be removably connected on the first mounting mechanism and fixing the first mounting mechanism; or installing the equipment that needs to be removably connected on the first mounting mechanism and the second mounting mechanism respectively, so as to realize the removable connection between different equipment; the present invention realizes the macro one-way locking connection, the two-way locking connection and the two-way freely released removable connection by fine-tuning the first plug plate 311 and / or the second plug plate 321, realizes different connection states between different components, and is simple to operate and convenient to control.

[0058] Furthermore, if Figure 1As shown, the first plug plate 311 and the second plug plate 321 extend from the first snap ring 31 and the second snap ring 32 respectively, and the connecting piece 8 is provided with a first plug hole and a second plug hole; the first stop distance nut 2, the connecting piece 8, the second stop distance nut 9, and the sleeve rod 10 form an accommodating space, and the steel ball 6 is installed in the accommodating space, wherein the accommodating space is a wedge-shaped space, and the wedge-shaped space in the present invention includes a variety of space forms, wherein the wedge-shaped space can be set to be close to the first stop distance nut 2 on the large gap side or close to the first stop distance nut 2 on the small gap side; specifically, when the wedge-shaped space is close to the first stop distance nut 2 on the large gap side, the steel ball 6 is installed in the accommodating space. When the ball 6 moves close to the second stop and distance nut 9, it is squeezed by the connector 8 and the sleeve rod 10 due to the narrowing of the accommodation space. At this time, the sleeve 1 and the sleeve rod 10 can move relatively close to each other but cannot move away from each other, that is, the connector can move shorter but cannot be extended, and the length limit control of the mobile connector is realized; when the wedge-shaped space is close to the first stop and distance nut 2 with a small gap, when the steel ball 6 moves close to the first stop and distance nut 2, it is squeezed by the connector 8 and the sleeve rod 10 due to the narrowing of the accommodation space. At this time, the sleeve 1 and the sleeve rod 10 can move relatively away from each other but cannot move close to each other, that is, the connector can move longer but cannot be shortened, and the length limit control of the mobile connector is realized. The first snap ring 31 and the second snap ring 32 are sequentially mounted on the connector 8 along the direction close to the second internal thread of the connector, and the first plug plate 311 and the second plug plate 321 respectively pass through the first plug hole and the second plug hole and extend into the accommodation space.

[0059] Specifically, the first locking and spacing nut 2 can be used to adjust the size of the accommodating space according to the actual needs of the connector, so as to achieve the adjustment of the locking sensitivity and the actual control needs of the connector.

[0060] Furthermore, if Figure 1 , Figure 2 , Figure 3 As shown, the first plug board 311 and the second plug board 321 extend to one end of the accommodation space and have a structure that changes from wide to narrow, or a structure that changes from narrow to wide, such as a wedge-shaped structure or a cone-shaped structure.

[0061] Furthermore, in a preferred embodiment, a motion transmission member 4 is further included, the motion transmission member 4 is installed inside the connecting member 8 and sleeved on the sleeve rod 10, the motion transmission member 4 is a structure that is narrowed from wide to narrow in the direction of radially extending outward, for example, the outer circumferential portion of the motion transmission member 4 is a wedge-shaped structure, and another example is a cone-shaped structure, the first plug plate 311 and the second plug plate 321 extend to one end of the accommodating space and are respectively a structure that is narrowed from wide to narrow in the direction of extension, when the first plug plate 311 and the second plug plate 321 are both close to the sleeve rod 10 and move, the first plug plate 311 and the second plug plate 321 are respectively moved to the motion transmission member 4. The motion transmission member 4 is on both sides of the first plug plate 311 and the second plug plate 321, respectively. At this time, the motion transmission member 4 is in contact with and squeezed with the first plug plate 311 and the second plug plate 321; in a variation, the motion transmission member 4 is in a structure that changes from narrow to wide along the direction of radially outward extension, and the first plug plate 311 and the second plug plate 321 extend to one end of the accommodating space and are in a structure that changes from narrow to wide along the direction of extension. When the first plug plate 311 and the second plug plate 321 move away from the sleeve rod 10, the first plug plate 311 and the second plug plate 321 move close to both sides of the motion transmission member 4, respectively. At this time, the motion transmission member 4 is in contact with and squeezed with the first plug plate 311 and the second plug plate 321, respectively.

[0062] Specifically, a limiting member is provided at one end of the sleeve rod 10 extending into the interior of the sleeve 1, and the limiting member can effectively prevent the sleeve rod 10 from being pulled out of the sleeve 1 and separating the sleeve rod 10 from the sleeve 1, so that the sleeve rod 10 and the sleeve 1 are always in a connected state, playing a good limiting role.

[0063] Specifically, Figure 1 As shown, in a preferred example, it also includes a steel ball sleeve 5, which is installed in the accommodating space, and the steel ball 6 is embedded in the steel ball sleeve 5, the upper end and the lower end of the steel ball 6 respectively protrude from the upper end and the lower end of the steel ball sleeve 5, and the upper end and the lower end of the steel ball 6 are respectively in contact with the connecting piece 8 and the sleeve rod 10; in a preferred example, the steel ball sleeve 5 is an annular structure, and the steel balls 6 are evenly or unevenly arranged along the circumference of the steel ball sleeve 5.

[0064] Specifically, Figure 1 As shown, it also includes a pressure return spring 7, which is installed in the accommodating space, one end of the pressure return spring 7 is installed on the second stop and distance nut 9, and the other end of the pressure return spring 7 is installed on the steel ball sliding sleeve 5; or the other end of the pressure return spring 7 is a free end, which can squeeze the pressure return spring 7 or leave the pressure return spring 7 when the steel ball sliding sleeve 5 moves.

[0065] Further, in a preferred embodiment, Figure 1As shown, one end of the pressure return spring 7 close to the motion transmission member 4 is a free end. When the second plug plate 321 or the motion transmission member 4 moves close to the steel ball 6, the second plug plate 321 or the motion transmission member 4 pushes the steel ball sleeve 5 to move, thereby driving the steel ball 6 and the steel ball sleeve 5 to move together. When the steel ball sleeve 5 drives the steel ball 6 to move close to the pressure return spring 7, the pressure return spring 7 is squeezed and shortened. When the force pushing the steel ball sleeve 5 is released, the spring rebound force of the pressure return spring 7 drives the steel ball sleeve 5 to drive the steel ball 6 to move away from the second stop distance nut 9.

[0066] It should be pointed out that the position of the pressure return spring 7 can be adjusted by adjusting the installation position of the second stop distance nut 9 on the connecting piece 8, so that the pressure return spring 7 is in a suitable position, and can cooperate with the steel ball sliding sleeve 5 to drive the steel ball 6 to make reciprocating motion, thereby realizing the movable state and the locked state of the connector. The structural design is exquisite and the operation is convenient.

[0067] Specifically, Figure 1 , Figure 2 , Figure 3 As shown, the movement of the first plug plate 311 and the second plug plate 321 may be achieved by various structural forms in addition to installing the first loosening screw 11 and the second loosening screw 12 .

[0068] Furthermore, if an electric actuator is used, in a preferred example, the electric actuator uses a motor or a linear motor to achieve the movement of the first plug plate 311 and the second plug plate 321 by motor drive or linear motor drive; for example, a pneumatic actuator can be used. In a preferred example, a pneumatic regulating valve or a pneumatic switch valve is used to drive the movement of the first plug plate 311 and the second plug plate 321.

[0069] Furthermore, the movement of the first plug board 311 and the second plug board 321 may be achieved by driving a phase change material actuator, a thermal expansion actuator, an intelligent material actuator, or an electromagnetic actuator.

[0070] Specifically, the phase change material actuator controls the temperature of the phase change material to achieve volume change to achieve driving force. For example, when the temperature of the phase change material rises to a certain value, the volume increases. The volume change causes the phase change material actuator to be displaced, thereby driving the first plug plate 311 and the second plug plate 321 to move.

[0071] Specifically, the thermal expansion actuator uses the thermal expansion characteristics of the device to achieve volume change and ultimately achieve driving force to drive the first plug plate 311 and the second plug plate 321 to move.

[0072] The smart material actuator controls any material including piezoelectric material, magnetostrictive material, conductive polymer material, electrorheological fluid, and magnetorheological fluid to realize driving force, thereby driving the first plug board 311 and the second plug board 321 to move.

[0073] The electromagnetic actuator realizes driving force by controlling the electromagnetic coil, generating magnetic force drive by energizing the coil, or generating current work by magnetic induction of the magnet to drive the first plug plate 311 and the second plug plate 321 to move.

[0074] Specifically, Figure 1 , Figure 2 , Figure 3 As shown, when the first tightening screw 11 and the second tightening screw 12 are tightened, the inner circles of the first clamping ring 31 and the second clamping ring 32 become smaller and tighten as a whole, so that the first plug plate 311 and the second plug plate 321 move closer to the axial direction of the connecting member 8 respectively.

[0075] The working principle of the present invention is described below by taking the first mounting mechanism and the second mounting mechanism as an example in which the first device and the second device are mounted respectively, and the first clamping ring 31 and the second clamping ring 32 are mounted respectively with the first loosening screw 11 and the second loosening screw 12, as follows:

[0076] like Figure 1As shown, the first device is installed at the leftmost end of the sleeve 1, and the second device is installed at the rightmost end of the sleeve rod 10. The accommodating space is a wedge-shaped structure. When the second device can only move to the left but not to the right relative to the sleeve 1, the large gap side of the wedge-shaped space is close to the first stop and distance nut 2, and the first tightening screw 11 is tightened. At this time, the diameter of the inner ring of the first clamping ring 31 becomes smaller due to the locking force of the first tightening screw 11, and the first plug plate 311 moves close to the sleeve rod 10. Due to the obstruction of the first stop and distance nut 2, the first plug plate 311 drives the motion transmission member 4 to move rightward when it moves close to the sleeve rod 10, thereby pushing the steel ball sliding sleeve 5 to drive the steel ball 6 to move, and finally the steel ball sliding sleeve 5 drives the steel ball 6 to move close to the second stop and distance nut 9. Since the area where the steel ball 6 is close is gradually narrowed and squeezed, the movement of the sleeve rod 10 to the right is restricted at this time, and the relative distance between the first device and the second device reaches the maximum; but since the space on the left side of the steel ball 6 is gradually widened, when the sleeve rod 10 moves to the left, the steel ball 6 is blocked by the sleeve The friction force of the rod 10 causes the rod 10 to slightly move to the left, thereby releasing the locked state of the steel ball 6, that is, the movement of the sleeve rod 10 to the left is not restricted, and the sleeve rod 10 can move to the left under the drive of the external force; when the first device and the second device move to the predetermined position and need to be fixed, the first loosening screw 11 and the second loosening screw 12 are tightened at the same time. Due to the obstruction of the first stop and spacing nut 2, the first plug plate 311, the motion transmission member 4, and the second plug plate 321 approach and squeeze the steel ball 6 in turn. At this time, due to the extension of the first plug plate 311, the motion transmission member 4, and the second plug plate 321, the left and right sides of the steel ball 6 are squeezed, that is, there is no active gap. At this time, the first device and the second device cannot move relative to each other, that is, the relative positions of the first device and the second device are fixed; similarly, when the large gap side of the wedge-shaped space is close to the second stop and spacing nut 9, the sleeve 1 and the sleeve rod 10 can be extended and moved, and the sleeve 1 and the sleeve rod 10 can be restricted from shortening and moving, or the connector can be locked in both directions.

[0077] It should be noted that when it is necessary to achieve one-way locking of the first device or the second device, it can be achieved not only by tightening the first tightening screw 11, but also by only tightening the second tightening screw 12, that is, when tightening the second tightening screw 12, since the motion transmission member 4 and the second plug plate 321 are blocked by the first stop and spacing nut 2, the second plug plate 321 approaches and pushes the steel ball sliding sleeve 5 to drive the steel ball 6 to move close to the second stop and spacing nut 9, so that the upper and lower ends of the steel ball 6 are respectively squeezed against the connecting member 8 and the sleeve rod 10, thereby achieving one-way locking and realizing one-way locking of the equipment.

[0078] In practical applications of the present invention, the adjustment of the connector includes the adjustment of various conditions, including not only the adjustment from a unidirectional movable state to a locked fixed state, from a bidirectional movable state to a locked fixed state, but also the adjustment from a fixed locked state to a unidirectional movable state or to a bidirectional movable state, which can be achieved by adjusting the first snap ring 31 and / or the second snap ring 32. At the same time, the structure of one end of the first snap ring 31 and the second snap ring 32 extending into the accommodating space can be either a structure that changes from wide to narrow or a structure that changes from narrow to wide. Therefore, the adjustment from a movable connection state to a locked fixed state or from a locked fixed state to a movable connection state in the present invention can be achieved by moving the first snap ring 31 and / or the second snap ring 32 in a radially outward direction or by moving the first snap ring 31 and / or the second snap ring 32 in a radially inward direction. In practical applications, the design can be made according to needs. Therefore, the present invention has a flexible structure and a wide range of applications. It can be applied to various occasions of mobile connectors and has important promotion significance.
