[0078] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0079] Some embodiments of the present invention are described in detail. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0080] Example

[0081] like Figures 1 to 7 As shown, this embodiment provides a locking device 100. The locking device 100 is used to unlock or lock a target part 210.

[0082] For details, please refer to Figure 1 and Figure 2 , the locking device 100 includes a support assembly 10, a cover plate 20, a base 30 and a lifting assembly 40. The cover plate 20 and the base 30 are arranged opposite to each other and spaced apart. The support assembly 10 is arranged on the base 30, and the support assembly 10 is located between the cover plate 20 and the base 30. The support assembly 10, the cover plate 20 and the base 30 together enclose a receiving space 50. The receiving space 50 is used to receive the target part 210. The lifting assembly 40 includes a connecting member 41 and a connecting shaft 42, and the connecting member 41 is provided with an inclined slide 43. In this embodiment, the slide 43 can be a hole passing through the connecting member 41, or a groove not passing through the connecting member 41. One end of the connecting shaft 42 is received in the slide 43, and the other end is connected to the support assembly 10. The connecting member 41 connects the support assembly 10 and the cover plate 20. Furthermore, the connecting member 41 can slide relative to the supporting assembly 10 and the cover plate 20 , thereby driving the connecting shaft 42 to slide along the slideway 43 to adjust the distance between the base 30 and the cover plate 20 .

[0083] When the locking device 100 in this embodiment unlocks or locks the target part 210, it only needs to drive the connecting member 41 to slide relative to the cover plate 20 and the supporting assembly 10 to adjust the distance between the cover plate 20 and the base 30. Thus, the accommodation space 50 is expanded or reduced, making it easier to place the target part 210 in the locking device 100 or unlock the target part 210 placed in the accommodation space 50.

[0084] In some embodiments, the connecting member 41 is further provided with a connecting groove 411, and the extending direction of the connecting groove 411 is the first direction X. The first direction X intersects with the extending direction of the slideway 43. A connecting base 21 is provided at one end of the cover plate 20. A buckle (not shown) is provided at the bottom end of the connecting base 21, and the buckle is slidably connected to the connecting groove 411. The arrangement of the buckle and the connecting groove 411 facilitates smoother sliding of the connecting member 41 relative to the cover plate 20 and the supporting assembly 10.

[0085] In some embodiments, the locking device 100 further includes a push-pull member 60, which is located at one side of the support assembly 10. The push-pull member 60 is located at a side of the cover plate 20 close to the base 30, and the connecting member 41 is fixedly connected to the push-pull member 60. The connecting member 41 is pulled away from the support assembly 10 or pushed toward the support assembly 10 by the push-pull member 60, so that the connecting member 41 moves back and forth in the slideway 43, thereby adjusting the distance between the cover plate 20 and the base 30.

[0086] In the present embodiment, the slideway 43 extends obliquely from the side of the connecting member 41 away from the cover plate 20 and the push-pull member 60 to the side of the connecting member 41 close to the cover plate 20 and the push-pull member 60. The number of slideways 43 is three, and the extension directions of the three slideways 43 are the same. In other embodiments, the slideway 43 may also extend obliquely from the side of the connecting member 41 close to the cover plate 20 and away from the push-pull member 60 to the side of the connecting member 41 away from the cover plate 20 and close to the push-pull member 60. At the same time, when the number of slideways 43 is multiple, the extension lengths and inclination angles of the multiple slideways 43 may be different. According to the specific situation of actually needing to raise the distance between the cover plate 20 and the base 30, the connecting shaft 42 can be selected to be placed in different slideways 43.

[0087] It is mainly explained that when one or more slideways 43 extend obliquely from the side of the connecting member 41 close to the cover plate 20 and away from the push-pull member 60 to the side of the connecting member 41 away from the cover plate 20 and close to the push-pull member 60, and the connecting shaft 42 slides and connects the slideway 43. In this case, when the push-pull member 60 is pulled outward, the connecting shaft 42 moves along the slideway 43 in the direction away from the cover plate 20, and the connecting shaft 42 drives the cover plate 20 to descend through the support assembly 10 to lock the target member 210. Conversely, when the push-pull member 60 is pushed inward, the connecting shaft 42 moves along the slideway 43 in the direction close to the cover plate 20, and the connecting shaft 42 drives the cover plate 20 to rise through the support assembly 10 to unlock the target member 210.

[0088] In the locking device 100, please combine Figure 1 When the target part 210 needs to be unlocked or placed in the locking device 100, first, the push-pull member 60 drives the connecting member 41 to move in a direction away from the support assembly 10, and the connecting member 41 slides relative to the support assembly 10 and the cover plate 20. Since one end of the connecting shaft 42 is slidably connected to the slideway 43, and the other end is connected to the support assembly 10. Therefore, the connecting shaft 42 slides in the slideway 43 in a direction away from the base 30 under the sliding of the connecting member 41, and the cover plate 20 rises relative to the base 30, thereby increasing the distance between the base 30 and the cover plate 20. At this time, the accommodating space 50 is enlarged, which facilitates the convenient placement of the target part 210 in the accommodating space 50. When the target part 210 needs to be unlocked, the push-pull member 60 drives the connecting member 41 to move in a direction close to the support assembly 10, and the connecting shaft 42 slides in the slideway 43 in a direction close to the base 30, so as to drive the cover plate 20 to descend relative to the base 30, thereby reducing the distance between the base 30 and the cover plate 20. At this time, the cover plate 20 locks the target component 210 into the receiving space 50 .

[0089] It should be noted that, in the present embodiment, the slide 43 includes an inclined guide section (not shown) and a stop section (not shown) located at opposite ends of the guide section and horizontally arranged along the first direction X. This ensures the stability of the cover 20 relative to the base 30 when the distance between the cover 20 and the base 30 is maximum or minimum. At the same time, in some embodiments, the number of slides 43 may be one or more. When the number of slides 43 is multiple, the multiple slides 43 are spaced apart. The inclination angles of the multiple slides 43 and one side of the connecting member 41 may be the same or different. And the extension directions of the multiple slides 43 may also be the same or different. This application does not limit this.

[0090] In some embodiments, the push-pull member 60 includes a first push-pull plate 61, a second push-pull plate 62 and a connecting plate 63. The first push-pull plate 61 and the second push-pull plate 62 are arranged opposite to each other and spaced apart along the second direction Y, the second direction Y is the extension direction of the cover plate 20, and the second direction Y is perpendicular to the first direction X. One end of the connecting plate 63 is fixedly connected to the first push-pull plate 61, and the other end is fixedly connected to the second push-pull plate 62. One end of the first push-pull plate 61 away from the connecting plate 63 and one end of the second push-pull plate 62 away from the connecting plate 63 are both connected to the support assembly 10. A push-pull handle 64 is provided in the middle of the connecting plate 63. The production personnel can pull the push-pull handle 64 outward (i.e., along the first direction X, in the direction away from the connecting member 41) or push it inward (i.e., along the first direction X, in the direction close to the connecting member 41). Alternatively, a connecting portion (not shown) may be provided in the middle of the connecting plate 63, and the connecting portion is used to connect a driving member (not shown), and the driving member drives the connecting plate 63 through the connecting portion to pull the first push-pull plate 61 and the second push-pull plate 62 in a direction away from the support assembly 10, or to push the first push-pull plate 61 and the second push-pull plate 62 in a direction close to the support assembly 10. The driving member may be a motor, and the present application does not limit the type of the driving member.

[0091] In some embodiments, please combine Figure 1 and Figure 2 , the support assembly 10 includes a support member 11 and a support base 12. The support base 12 is located on a side of the base 30 close to the cover plate 20, one end of the support member 11 penetrates the support base 12 to connect to the base 30, and the other end is connected to the cover plate 20. In this embodiment, the number of the support members 11 and the support base 12 is two, and the two support members 11 and the two support bases 12 are located on opposite sides of the accommodating space 50 along the second direction Y. The two support members 11 are fixedly connected to the opposite ends of the cover plate 20 to ensure the balance and stability of the cover plate 20 when locking the target member 210. At the same time, the number of the connecting shaft 42 and the connecting member 41 is also two. After the first push-pull plate 61 is fixedly connected to one connecting member 41, one end of a connecting shaft 42 is slidably connected to the connecting member 41, and the other end is transmission-connected to one support member 11. After the second push-pull plate 62 is fixedly connected to another connecting member 41, one end of another connecting shaft 42 is slidably connected to the connecting member 41, and the other end is transmission-connected to another support member 11.

[0092] For details, please refer to Figures 4 to 7The support member 11 includes a first support rod 13, a second support rod 14 and a fixing member 15. The first support rod 13 and the second support rod 14 are arranged opposite to each other and spaced apart along the first direction X, and one end of the first support rod 13 and the second support rod 14 away from the support base 12 are fixedly connected to the cover plate 20. The fixing member 15 is partially placed between the first support rod 13 and the second support rod 14, and abuts against the cover plate 20 and the support base 12. The first support rod 13 and the second support rod 14 are respectively arranged to abut against one end of the cover plate 20, so that the cover plate 20 can be supported more stably, so that the cover plate 20 is more tightly locked when the target member 210 is locked.

[0093] In this example, see Figure 6 and Figure 7 The first support rod 13 includes a first lifting portion 131 and a first supporting portion 132, one end of the first supporting portion 132 is movably connected to the first lifting portion 131, and the other end thereof penetrates the supporting base 12. The second support rod 14 includes a second lifting portion 141 and a second supporting portion 142, one end of the second supporting portion 142 is movably connected to the second lifting portion 141, and the other end thereof penetrates the supporting base 12. In this way, the first lifting portion 131 can rise or fall relative to the first supporting portion 132 in a direction away from / close to the supporting base 12, and the second lifting portion 141 can rise or fall relative to the second supporting portion 142 in a direction away from / close to the supporting base 12.

[0094] For further information, please refer to Figure 4 The fixing member 15 includes a first fixing block 151 and a second fixing block 152, and the first fixing block 151 and the second fixing block 152 are arranged opposite to each other along the second direction Y. The first fixing block 151 is fixedly connected to the second fixing block 152, and the opposite ends of the first fixing block 151 respectively abut the first lifting part 131 and the second lifting part 141. The second fixing block 152 is located in the space surrounded by the first support rod 13, the second support rod 14, the cover plate 20 and the support base 12, and the second fixing block 152 abuts the cover plate 20 and the support base 12. Please combine Figure 5 , the connecting shaft 42 is fixedly connected to the first fixed block 151. In this embodiment, the diameter of the first lifting part 131 is set to be larger than the diameter of the first supporting part 132, and the diameter of the second lifting part 141 is set to be larger than the diameter of the second supporting part 142. One end of the first fixed block 151 abuts against one end of the first lifting part 131 close to the first supporting part 132, and the other end of the first fixed block 151 abuts against one end of the second lifting part 141 close to the second supporting part 142. In this way, when the connecting shaft 42 slides in the slideway 43. The first fixed block 151 can drive the first lifting part 131 to rise or fall relative to the first supporting part 132 and the second lifting part 141 to rise or fall relative to the second supporting part 142.

[0095] It is understandable that, although the term "diameter" is used for explanation, the term "diameter" should be understood in a broad sense, and the term "diameter" only refers to the direction of the cross section of the first lifting portion 131 and the cross section of the first supporting portion 132, and does not limit the shape of the cross section. For example, in this embodiment, the cross section of the first lifting portion 131 and the cross section of the first supporting portion 132 are both circular, and in other embodiments, the cross section of the first lifting portion 131 and the cross section of the first supporting portion 132 may be elliptical, semicircular, triangular, square, etc.

[0096] In some embodiments, a moving gap 80 is formed between the second fixing block 152 and the first supporting rod 13 , and the moving gap 80 is connected to the accommodating space 50 . When the connecting shaft 42 slides in the slideway 43 , the second fixing block 152 moves back and forth in the moving gap 80 .

[0097] In this embodiment, please also refer to Figure 1 , Figure 4 and Figure 5 When the push-pull member 60 is pulled outward, the connecting member 41 slides relative to the connecting base 21 under the pulling force of the push-pull member 60, and at the same time, the push-pull member 60 drives the second fixed block 152 to move in the moving gap 80 in the direction away from the first support rod 13. After the second fixed block 152 abuts against the second support rod 14, the push-pull member 60 continues to be pulled outward, and the connecting shaft 42 will slide along the slideway 43 in the direction close to the cover plate 20. The connecting shaft 42 drives the first fixed block 151 and the second fixed block 152 to rise. Since the first fixed block 151 abuts against the first lifting part 131 and the second lifting part 141, the first fixed block 151 drives the first lifting part 131 and the second lifting part 141 to rise to link the cover plate 20 to rise. The accommodating space 50 is enlarged, which is convenient for the placement of the target part 210 or unlocking the target part 210. On the contrary, when the push-pull member 60 is pushed inward, the connecting shaft 42 will slide along the slideway 43 in a direction away from the cover plate 20, and the first lifting part 131 and the second lifting part 141 will descend to link the cover plate 20 to descend. The connecting shaft 42 continues to slide along the slideway 43 in a direction away from the cover plate 20, and the second fixing block 152 and the second support rod 14 are separated.

[0098] For further information, please refer to Figures 1 to 4 The locking device 100 further includes a positioning column 31 and a pull plate 32. A receiving groove 33 is provided on the side of the base 30 away from the cover plate 20. The pull plate 32 is placed in the receiving groove 33. The positioning column 31 passes through the base 30 to fix the pull plate 32. The pull plate 32 is connected to the support assembly 10. The positioning column 31 is used to position the target part 210 placed in the receiving space 50. Figure 2As shown, the base 30 is provided with a first mounting hole 34 and a through hole 35. In this embodiment, the through hole 35 is located in the middle of the base 30, and the first mounting hole 34 is located on one side of the through hole 35. The first support rod 13 and the second support rod 14 pass through the first mounting hole 34 and are fixedly connected to the base 30. Figure 3 The through hole 35 is connected to the receiving groove 33. A hollow cylindrical tube is provided in the middle of the pull plate 32, and the cylindrical tube passes through the through hole 35. The positioning column 31 is sleeved and connected to the cylindrical tube of the pull plate 32. Figure 4 The first support rod 13 and the second support rod 14 are both provided with a snap-fitting groove 16 at one end close to the base 30, and the outer wall of the pull plate 32 is snapped into the snap-fitting groove 16. The pull plate 32 is used to transmit the first support rod 13 and the second support rod 14 to drive the cover plate 20 to move in a direction close to the base 30.

[0099] In this embodiment, the other end of the pull plate 32 away from the base 30 is driven to connect to an external power member (not shown), and the external power member drives the pull plate 32 to move away from the cover plate 20, so that the pull plate 32 drives the first support rod 13, the second support rod 14 and the cover plate 20 to move toward the base 30. The external power member is a hydraulic cylinder. In other embodiments, the external power member can also be other components besides the hydraulic cylinder, and the present application is not limited to this.

[0100] On the one hand, the setting of the positioning column 31 can prevent the target part 210 placed in the accommodating space 50 from shaking and damaging the target part 210 when it is not positioned. On the other hand, after the cover plate 20 is pressed against the target part 210, the first support rod 13, the second support rod 14 and the cover plate 20 are driven by the pull plate 32 to move the cover plate 20 toward the base 30 again, so that the cover plate 20 further locks the target part 210. It is ensured that the target part 210 can be completely and firmly fixed in the locking device 100.

[0101] Figures 1 to 7The locking device 100 shown, first, pulls the push-pull member 60 outward, so that the connecting shaft 42 slides along the direction of the slideway 43, and the sliding force of the connecting shaft 42 drives the first lifting part 131 to rise in the direction away from the base 30. The rise of the first lifting part 131 also links the cover plate 20 to rise, and the accommodating space 50 is increased, which is convenient for placing the target part 210 in the accommodating space 50. At the same time, the positioning column 31 located in the middle of the base 30 and the pull plate 32 positions the target part 210 on the base 30 to prevent the target part 210 from shaking. Then, push the push-pull member 60 inward, so that the connecting shaft 42 slides in the opposite direction of the slideway 43, and the sliding force of the connecting shaft 42 drives the first lifting part 131 to descend in the direction close to the base 30. The descent of the first lifting part 131 links the cover plate 20 to descend. Finally, the cover plate 20 will press against the target part 210 to lock. The locking device 100 can quickly lock or unlock the target part 210 , thereby improving the disassembly efficiency of the target part 210 .

[0102] like Figures 8 to 10 As shown, this embodiment further provides a locking device 200. The locking device 200 includes a locking device 100 and a target part 210.

[0103] In some embodiments, please refer to Figure 8 and Fig. 9 The cover plate 20 includes a pressure head 22, and a snap-in hole 23 is provided in the middle of the cover plate 20. The pressure head 22 snaps into the snap-in hole 23. In this embodiment, the pressure head 22 includes two hollow cylindrical tubes, and the two cylindrical tubes are coaxially arranged, and the outer wall diameters of the two cylindrical tubes are different. In this way, the outer walls of the two cylindrical tubes form a step surface, and the inner wall of the snap-in hole 23 can also be provided with a step surface. When the pressure head 22 snaps into the snap-in hole 23, the step surface formed by the outer walls of the two cylindrical tubes fits the step surface formed by the inner wall of the snap-in hole 23.

[0104] Furthermore, the pressing head 22 is provided with a locking hole 221, and the locking hole 221 passes through two cylindrical tubes, and the inner wall of the locking hole 221 is provided with a pressing surface P2. An inclined surface P1 is provided at one end of the target part 210, and the inclined surface P1 extends obliquely from one end of the target part 210 to the middle of the target part 210. When the cover plate 20 moves toward the base 30 to press the target part 210 placed in the locking device 100, the pressing surface P2 fits the inclined surface P1. In other embodiments, the pressing surface P2 can also be directly provided on the inner wall of the engaging hole 23. When the cover plate 20 is subjected to a downward force and is pressed toward the target part 210, one end of the target part 210 passes through the engaging hole 23, so that the pressing surface P2 fits the inclined surface P1.

[0105] It should be noted that an inclined surface P1 is provided at one end of the target part 210 , so that when the cover plate 20 descends to press the target part 210 , it is ensured that the target part 210 can be more firmly engaged in the locking hole 221 .

[0106] In some embodiments, Fig.10 As shown, the other end of the target part 210 is provided with a second mounting hole 211, the inner wall of the second mounting hole 211 is provided with a thread groove 212, and the outer wall of the positioning column 31 is provided with a thread protrusion 311, and the thread protrusion 311 is placed in the thread groove 212. In this embodiment, first, the end of the positioning column 31 close to the cover plate 20 is extended into the second mounting hole 211. Then, the target part 210 is rotated so that the thread protrusion 311 is placed in the thread groove 212. In this way, one end of the target part 210 is positioned on the positioning column 31. Then, the target part 210 is locked by the cover plate 20, which ensures the stability of the target part 210 fixed to the locking device 100.

[0107] The above implementation modes are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above preferred implementation modes, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
