Of course, they are merely examples and are not intended to limit the present utility model.

[0037] Reference is made below to Figures 1-3 describe the locking device 200 according to an embodiment of the present utility model.

[0038] As Figures 1-3 shown, the locking device 200 according to an embodiment of the present utility model includes: a locking box 10, a locking member 20, and a guiding member 30.

[0039] The locking box 10 is adapted to be installed on the ground, and a locking cavity 11 is formed in the locking box 10. The locking member 20 is movably disposed in the locking box 10 to selectively protrude from the locking box 10. Unlocking surfaces 21 and locking surfaces 22 are alternately formed on the outer circumference of the locking member 20 in the circumferential direction. The guiding member 30 is received in the locking cavity 11 and cooperates with the locking member 20. The guiding member 30 is adapted to drive the locking member 20 to rotate in the circumferential direction to switch the positions of the unlocking surface 21 and the locking surface 22.

[0040] It should be noted that after the locking box 10 is installed on the ground, a locking cavity 11 is formed inside the box. The guiding member 30 is disposed in the locking cavity 11, and the guiding member 30 cooperates with the locking member 20. In this way, when the locking member 20 moves in the locking box 10, that is, when the locking member 20 moves in the locking cavity 11, it will be guided by the guiding member 30, so that the locking member 20 can rotate axially to switch the positions of the unlocking surface 21 and the locking surface 22. Furthermore, it is easier to use the locking member 20 to lock the to-be-locked member, and the locking surface 22 can prevent the to-be-locked member from being disengaged.

[0041] Wherein, the to-be-locked member can abut against the unlocking surface 21 of the locking member 20. In this way, the locking member 20 will be pressed into the locking box 10 by the to-be-locked member. In this way, when the locking member 20 moves, it can be guided by the guiding member 30 to rotate, and then switch the unlocking surface 21 to the locking surface 22 and fix the to-be-locked member.

[0042] Thus, the locking member 20 can move within the locking box 10, and when the locking member 20 moves towards the inside of the locking cavity 11, it can be guided by the guiding member 30 to rotate circumferentially, so that the locking member 20 can switch between the unlocking surface 21 and the locking surface 22, thereby being able to fix the member to be locked.

[0043] According to the locking device 200 of an embodiment of the present utility model, when the member to be locked presses against the unlocking surface 21, the locking member 20 can be pressed into the locking box 10. The locking member 20 can switch the unlocking surface 21 to the locking surface 22 under the guidance of the guiding member 30, thereby fixing the member to be locked, making the locking method of the member to be locked simpler. At the same time, the locking member 20 will not disengage from the locking box 10.

[0044] In some embodiments, as Figures 1-3 shown, a guiding inclined surface 31 extending circumferentially and gradually decreasing in height is formed on the guiding member 30. A guiding portion 23 cooperating with the guiding inclined surface 31 is provided on the locking member 20. The locking member 20 moves towards the direction of being received in the locking cavity 11 to rotate under the cooperation of the guiding portion 23 and the guiding inclined surface 31.

[0045] It should be noted that when the locking member 20 moves towards the direction of being received in the locking cavity 11, the guiding portion 23 on the locking member 20 can cooperate with the guiding inclined surface 31 on the guiding member 30. The guiding inclined surface 31 extends circumferentially on the guiding member 30 and gradually decreases in height. In this way, when the locking member 20 moves, the guiding portion 23 and the guiding inclined surface 31 cooperate to make the locking member 20 rotate, and further make the unlocking surface 21 and the locking surface 22 of the locking member 20 switch, making the use of the locking device 200 more convenient.

[0046] Thus, the guiding portion 23 of the locking member 20 will cooperate with the guiding inclined surface 31 of the guiding member 30. In this way, when the locking member 20 moves towards the direction of being received in the locking cavity 11, the locking member 20 rotates under the cooperation of the guiding portion 23 and the guiding inclined surface 31, so that the locking member 20 can switch between the unlocking surface 21 and the locking surface 22.

[0047] In other embodiments, as Figures 1-3 shown, the guiding portion 23 of the locking member 20 is configured as a strip-shaped protrusion, and the edge of the strip-shaped protrusion is formed as an inclined surface. The inclined surface at one end of the strip-shaped protrusion facing the guiding member 30 cooperates with the guiding inclined surface 31. At the same time, a limiting member 12 is provided at one end of the locking box 10 connected to the locking member 20. The limiting member 12 is also formed with an inclined surface and cooperates with the inclined surface at the other end of the strip-shaped protrusion. The limiting member 12 can prevent the locking member 20 from rotating too much each time, that is, the locking member 20 can only switch between the unlocking surface 21 and the locking surface 22 once each time it moves, thereby ensuring the locking effect of the locking member 20.

[0048] In some embodiments, such as Figures 1-3 As shown, the guiding member 30 is configured as a cylindrical body, and a guiding inclined surface 31 continuously extending in the circumferential direction is formed at the top end of the cylindrical body.

[0049] It should be noted that the guiding member 30 is configured as a cylindrical body, so that the locking member 20 will partially extend into the cylindrical body during movement, so that the locking member 20 moves along the length direction of the cylindrical body during movement, which ensures the fixed direction of the locking member 20 during movement. At the same time, the guiding inclined surface 31 formed at the top end of the cylindrical body extends continuously in the circumferential direction. When the locking member 20 moves in the direction of being received in the locking cavity 11, the guiding portion 23 of the locking member 20 can cooperate with the guiding inclined surface 31 to ensure that the locking member 20 can rotate, and then switch the unlocking surface 21 and the locking surface 22 of the locking member 20.

[0050] Therefore, the guiding member 30 configured as a cylindrical body can ensure that the movement direction of the locking member 20 does not change during the movement of the locking member 20, so that the locking effect of the locking member 20 during locking is better. At the same time, a guiding inclined surface 31 is formed at the top end of the cylindrical body, so that the cooperation between the guiding portion 23 and the guiding inclined surface 31 is easier, and thus it is more convenient to guide the locking member 20.

[0051] In some embodiments of the present application, the guiding inclined surfaces 31 are configured as a plurality of circumferentially spaced apart at the end of the cylindrical body, and the guiding portions 23 are configured as a plurality corresponding to the plurality of guiding inclined surfaces 31. Each guiding inclined surface 31 gradually decreases in height in the same circumferential direction. The plurality of guiding inclined surfaces 31 and the plurality of guiding portions 23 are in one-to-one correspondence and cooperation, so that the relative movement between the guiding portion 23 and the cylindrical body is more stable, avoiding the inclination of the cylindrical body during movement, and ensuring the smooth rotation of the locking member 20.

[0052] Such as Figure 7 As shown, the guiding inclined surfaces 31 in the present application are configured as two symmetrically arranged ones, and the two guiding inclined surfaces 31 are arranged in a surrounding and enclosing manner. The guiding member 30 is composed of two semi-cylindrical bodies, and each guiding inclined surface 31 is arranged at the end of the semi-cylindrical body.

[0053] In some embodiments of the present application, in the projection in the axial direction of the cylinder body, the guiding inclined surface 31 is configured as an annular shape, and the guiding inclined surface 31 extends spirally along the axis of the cylinder body. The projection in the axial direction of the barrel body can be understood as that the guiding inclined surface 31 is the end face of the cylinder body, that is, the end face used for cooperating with the locking member 20. And the guiding inclined surface 31 is a complete annular shape, which increases the contact area with the locking member 20. No matter what position state the locking member 20 is in, it can cooperate with the guiding inclined surface 31, improving the reliability of the cooperation of the locking device 200. In addition, the guiding inclined surface 31 is configured to extend spirally along the axis of the cylinder body, making the processing method of the guiding inclined surface 31 more convenient. It can be formed by processing or cutting the end face structure of the cylinder body. The processing is simple and the forming is convenient.

[0054] In some embodiments, as Figures 1-3 shown, the locking device 200 further includes: an elastic member 32, and the elastic member 32 is received in the cylinder body and connected to the locking member 20.

[0055] It should be noted that the elastic member 32 is arranged in the cylinder body and connected to the locking member 20. In this way, when the locking member 20 moves towards the guiding member 30, it will press against the elastic member 32. After the unlocking surface 21 and the locking surface 22 of the locking member 20 are switched, the elastic member 32 will apply an elastic force to the locking member 20, so that the locking member 20 can protrude from the locking box 10, thereby realizing locking and unlocking.

[0056] Thus, by arranging the elastic member 32 in the cylinder body and the elastic member 32 is also connected to the locking member 20, after the unlocking surface 21 and the locking surface 22 of the locking member 20 are switched, the elastic member 32 can act on the locking member 20 to reset the locking member 20 and realize locking or unlocking.

[0057] Among them, the elastic member 32 can be configured as a spring. In this way, it is easier to arrange the elastic member 32 in the cylinder body, and the connection with the locking member 20 is simpler. After being squeezed by the locking member 20, the spring can provide an elastic force to the locking member 20 so that the locking member 20 can be reset.

[0058] In some embodiments, as Figures 1-3 shown, the locking member 20 is configured as a column and is adapted to move axially to be received in the cylinder body. An unlocking surface 21 inclined relative to the axis and a locking surface 22 arranged parallel to the axis are formed at the end of the locking member 20.

[0059] It should be noted that the locking member 20 is configured as a column, which makes the rotation of the locking member 20 easier. At the same time, an unlocking surface 21 inclined relative to the axis and a locking surface 22 parallel to the axis are formed on the end surface of the locking member 20. In this way, when the unlocking surface 21 abuts against the member to be locked, the member to be locked can press against the inclined unlocking surface 21 and cause the locking member 20 to move towards the cylinder body, so that the locking member 20 rotates and switches the unlocking surface 21 to the locking surface 22, and the locking surface 22 abuts against the member to be locked to achieve locking.

[0060] Therefore, the locking member 20 is configured as a column, which makes the rotation of the locking member 20 easier. At the same time, the unlocking surface 21 is inclined relative to the axis, and the locking surface 22 is parallel to the axis. In this way, the unlocking surface 21 can abut against the member to be locked and be squeezed by the member to be locked, so that the locking member 20 rotates, so that the locking member 20 can be switched from the unlocking surface 21 to the locking surface 22 and fix the member to be locked.

[0061] In some embodiments, as Figures 1-3 shown, the locking device 200 further includes: a locking member 40, and the locking member 40 selectively locks the locking member 20 with the locking box 10 to limit the locking member 20 from protruding from the locking housing.

[0062] It should be noted that the locking member 40 selectively locks the locking member 20 with the locking box 10, that is, when the locking member 20 protrudes from the locking housing and the locking surface 22 abuts against the member to be locked, the locking member 40 locks the locking member 20 with the locking box 10, so that the locking member 20 will not move again, thereby ensuring the fixing effect of the locking member 20 on the member to be locked. At the same time, when the locking member 40 does not lock the locking member 20 with the locking box 10, the locking member 20 can move and unlock, so that the member to be locked can move again.

[0063] Therefore, the locking member 40 can lock the locking member 20 with the locking box 10 so that the locking member 20 will no longer move, so that the locking member 20 can keep protruding from the locking housing, thereby better fixing the member to be locked, and the locking member 40 can also make the locking member 20 and the locking box 10 unlocked, so that the locking member 20 can move and unlock.

[0064] In some embodiments, as Figures 1-3 shown, the locking member 40 is configured as a locking pin and is adapted to move radially along the guiding structure on the locking box 10, and a magnetic attracting member 41 is provided on the locking pin to selectively adsorb to the locking box 10 or the locking member 20.

[0065] It should be noted that the locking member 40 is configured as a locking pin, and the locking pin can move radially along the guiding structure on the locking box 10. In this way, when the locking pin moves towards the locking member 20, it can be inserted into the locking member 20 to lock the locking member 20. When the locking pin moves in the direction away from the locking member 20, the locking pin can unlock the locking member 20 so that the locking member 20 can rotate. At the same time, a magnetic attachment 41 is also provided on the locking pin. In this way, when the locking pin locks the locking member 20, the magnetic attachment 41 adsorbs to the locking member 20, and the magnetic attachment 41 can enhance the fixing effect of the locking pin, so as to better lock the locking member 20. When the locking pin does not lock the locking member 20, the magnetic attachment will adsorb to the locking box 10, which ensures that the locking pin will not fall off from the locking box 10 and avoid loss.

[0066] Thus, the locking member 40 is configured as a locking pin and moves radially along the guiding structure. In this way, the locking pin can move towards the locking member 20 and be inserted into the locking member 20 to lock the locking member 20, or the locking pin moves away from the locking member 20 to unlock the locking member 20. At the same time, when the magnetic attachment 41 on the locking pin adsorbs to the locking member 20, it can strengthen the fixing effect of the locking pin to ensure the locking effect of the locking member 20, and when the magnetic attachment 41 adsorbs to the locking box 10, it can prevent the locking pin from being lost.

[0067] In some embodiments, as Figures 1-3 shown, the magnetic attachments 41 are configured as two and are respectively arranged at both ends of the locking pin.

[0068] It should be noted that the magnetic attachment 41 can be divided into a first magnetic attachment 411 and a second magnetic attachment 412, and the two are located at both ends of the locking pin. In this way, when the locking pin locks the locking member 20, the first magnetic attachment 411 adsorbs to the locking member 20, and the second magnetic attachment 412 adsorbs to the locking box 10, so as to further improve the locking effect of the locking pin. When the locking pin does not lock the locking member 20, the first magnetic attachment 411 adsorbs to the locking box 10 to prevent the locking pin from being lost.

[0069] Thus, two magnetic attachments 41 are provided. In this way, when the locking pin locks the locking member 20, the two magnetic attachments 41 can respectively adsorb to the locking member 20 and the locking box 10, so as to further improve the locking effect of the locking pin.

[0070] In some embodiments, as Figures 1-3 shown, the locking device 200 further includes: a support platform 50, the support platform 50 is arranged on the top of the locking box 10, and a through hole adapted for the locking member 20 to pass through is formed on the support platform 50.

[0071] It should be noted that the support platform 50 is arranged on the top of the locking box 10, and a through hole for passing through the locking member 20 is arranged on the support platform 50. In this way, the support platform 50 can guide the locking member 20 to a certain extent, so as to ensure that the movement direction of the locking member 20 remains unchanged. At the same time, the support platform 50 can support the member to be locked, so that the locking member 20 can better lock the member to be locked.

[0072] Among them, the support platform 50 can be constructed as a U-shaped plate. One side of the two sides of the U-shaped plate is connected to the locking box 10, and the other side is in contact with the member to be locked. In this way, it can provide a certain support for the member to be locked.

[0073] Therefore, the support platform 50 is arranged on the top of the locking box 10, so that the support platform 50 can provide a certain support for the member to be locked. At the same time, a through hole is also arranged on the support platform 50 and the locking member 20 will pass through the through hole, so that the support platform 50 will play a certain guiding role for the locking member 20.

[0074] The present utility model also proposes a locking assembly 1000.

[0075] As Figures 4-6 shown, the locking assembly 1000 according to an embodiment of the present utility model includes: a locking device 200 and a moving platform 100.

[0076] The locking device 200 is constructed as the locking device 200 in any one of the above embodiments, and a locking hole adapted to cooperate with the locking member 20 is formed on the moving platform 100.

[0077] It should be noted that when the moving platform 100 moves to the locking device 200, the side surface of the moving platform 100 will abut against the unlocking surface 21 and press the locking member 20 into the locking box 10. The guiding portion 23 of the locking member 20 cooperates with the guiding member 30 so that the locking member 20 rotates. After the member to be locked switches the unlocking surface 21 to the locking surface 22, the locking hole of the moving platform 100 will be aligned with the locking member 20. The locking member 20 protrudes from the locking box 10 under the action of the elastic member 32. In this way, the locking member 20 will pass through the locking hole to fix the moving platform 100.

[0078] Furthermore, the locking member 40 on the lock can lock the locking member 20 when the locking member 20 fixes the moving platform 100, so that the locking member 20 cannot move anymore, so that the moving platform 100 can be well fixed when it is located on an inclined plane or a vehicle.

[0079] According to the locking assembly 1000 of the embodiment of the utility model, the side of the mobile platform 100 can be abutted against the unlocking surface 21 of the locking member 20, so that the locking member 20 is pressed into the locking box 10, and the guide portion 23 of the locking member 20 cooperates with the guide component 30, so that the locking member 20 can rotate in the circumferential direction, thereby switching the unlocking surface 21 to the locking surface 22. At the same time, after the switching is completed, the locking member 20 will protrude from the locking box 10 under the action of the elastic member 32, so that the locking member 20 will cooperate with the locking hole to fix the mobile platform 100, which makes the locking method of the member to be locked simpler, and the locking member 20 will not detach from the locking box 10.
