[0039] See also Figure 1-8 , this article provides a mobile workstation 100, which can be specifically a work vehicle, such as a shooting tool vehicle, but is not limited to other scenarios, including a linkage locking structure 10, the linkage locking structure 10 includes a connecting component 1 and a locking component 2, the connecting component 1 includes a first connecting member 11 for connecting a first object and a second connecting member 12 for connecting a second object, the second connecting member 12 is connected to the first connecting member 11, and has a movable end 121; one end of the locking component 2 is movably set on the first connecting member 11, and the other end is passed through the movable end 121 and protrudes from the movable end, the two ends of the locking component 2 are configured to be able to move relative to each other to lock the first object to the first connecting member 11, and to enable the movable end 121 to move to lock the second object to the second connecting member 12.

[0040] In this article, see Figure 5-6 When the user operates the locking assembly 2, the two ends of the locking assembly 2 can move relatively toward each other, so that one end of the locking assembly 2 can lock the first connecting member 11 and the first object; the other end of the locking assembly 2 can move with the movable end 121, so that the movable end 121 is pressed on the second object to lock and install the second object and the second connecting member 12. In summary, the user in this article can lock the first object and the second object through a single operation, and can conveniently and quickly complete the connection between the first object and the second object. It can be understood that the two ends of the locking assembly 2 are configured to be able to move relatively toward each other, and can also be configured to move relatively away from each other. The user can operate the locking assembly 2 in the unlocking direction, so that one end of the locking assembly 2 can unlock the first connecting member 11 and the first object, and the other end of the locking assembly 2 moves in the direction away from each other to release the support on the movable end 121, thereby unlocking the second connecting member 12 and the second object. It is worth to understand that, protruding outside the movable end 121 specifically means protruding from the side of the movable end 121 away from the first connecting member 11.

[0041] Specifically, see Figure 1-4 The mobile workstation 100 may further include a mobile body 30, the first object may be a truss 201, the second object may be a support column 202, and the interlocking locking structure 10 may install the truss 201 and the two support columns 202 to form a truss 20, and the user may install the truss 20 on the mobile body 30 as needed.

[0042] Specifically, each interlocking locking structure 10 includes a first connecting member 11, a second connecting member 12 and a locking assembly 2, the first connecting member 11 is provided with a connecting groove 111, the second connecting member 12 includes a pipe clamp, the pipe clamp is connected to the first connecting member 11, and has a movable end 121, wherein the two support columns 202 can be accommodated in the pipe clamps of the two interlocking locking structures 10, and the two ends of the truss 201 can be respectively accommodated in the connecting grooves 111 of the two interlocking locking structures 10; the locking assembly 2 is movably arranged on the first connecting member 11, and one end passes through the movable end 121, wherein both ends of the locking assemblies 2 of the two interlocking locking structures 10 can be configured to be able to move relative to each other, so that the locking assembly 2 can lock the two ends of the truss 201 in the corresponding connecting grooves 111 respectively, and the corresponding movable end 121 moves to be able to lock the corresponding support column 202 in the corresponding pipe clamp, so that the two support columns 202 can support the truss 201.

[0043] In this article, see Figure 3 One end of the locking assembly 2 is movably provided on the first connecting piece 11. When the user operates the locking assembly 2 to move and lock the two ends of the truss beam 201 in the connecting groove 111, since the other end of the locking assembly 2 passes through the movable end 121 of the pipe clamp, the user can operate the locking assembly 2 so that the trigger end of the locking assembly 2 moves toward the first connecting piece 11, thereby locking the support column 202 in the pipe clamp, thereby completing the connection between the support column 202 and the truss beam 201 more conveniently and quickly, which is convenient for the user to use.

[0044] On one hand, a transfer connecting post 2021 is provided at the bottom of the support post 202. Both the upper and lower ends of the transfer connecting post 2021 are threaded. The upper end can be threadedly connected to the support post 202, and the lower end can be threadedly connected to the tubular member of the mobile body 30, thereby completing the installation of the truss 20. It is worth noting that the middle portion of the transfer connecting post 2021 also has a plurality of mating holes 2022, which can be inserted into auxiliary tools such as wrenches to rotate the transfer connecting post 2021, thereby facilitating the removal and installation of the transfer connecting post 2021.

[0045] On the one hand, see Figure 2 、 Figure 4 Multiple expansion ports 2011 are provided on both sides of the truss beam 201. These expansion ports 2011 include at least one of a 1 / 4 threaded port, a 3 / 8 threaded port, a positioning port, and a slide bar. Specifically, the positioning port may include a 1 / 4 positioning port or a 3 / 8 positioning port, and the slide bar may include a NATO slide bar, a Manfrotto slide bar, an Aqua slide bar, or the like. These can be used to expand various accessories onto the mobile body 30, thereby increasing the storage space of the mobile body 30 and facilitating user access.

[0046] See also Figure 5-6, the locking assembly 2 includes a first locking member 21 and a second locking member 22. The first connecting member 11 has a receiving groove 112. The first locking member 21 is movably disposed in the receiving groove 112. One end of the second locking member 22 extends into the receiving groove 112 and is linked with the first locking member 21, and the other end passes through the movable end 121. The first locking member 21 and the second locking member 22 are configured to be able to move relatively towards each other or relatively away from each other, so that the first locking member 21 can lock or unlock the first object, and the second locking member 22 can press or release the pressing on the movable end 121, so that the second connecting member 12 is locked or unlocked with the second object. It can be understood that the relative movement of the first locking member 21 and the second locking member 22 towards each other can be a state where the first locking member 21 and the second locking member 22 seem to move in a direction relatively towards each other during the user's operation of locking; the relative movement of the first locking member 21 and the second locking member 22 away from each other can be a state where the first locking member 21 and the second locking member 22 seem to move in a direction relatively away from each other during the user's operation of unlocking. When the user operates the second locking member 22 to rotate in the locking direction, it can make the second locking member 22 move relatively towards the first locking member 21, thereby pressing the movable end 121, so that the movable end 121 locks the second object and the second connecting member 12. During this process, the first locking member 21 can move relatively towards the second locking member 22, so that the first locking member 21 can lock the first object to the first connecting member 11. When the user operates the second locking member 22 to rotate in the unlocking direction, it can make the second locking member 22 move relatively away from the first locking member 21, release the pressing on the movable end 121, thereby releasing the locking of the movable end 121 on the second object and the second connecting member 12; and the first locking member 21 can move relatively away from the second locking member 22, thereby unlocking the first connecting member 11 and the first object.

[0047] Please refer to FIGS. 5-7. The second locking member 22 includes a locking shaft 221 and a locking wrench 222. One end of the locking shaft 221 extends into the receiving groove 112 and is threadedly connected to the first locking member 21. The other end of the locking shaft 221 passes through the movable end 121 and engages with the locking wrench 222. Rotating the locking wrench 222 can cause the locking shaft 221 and the first locking member 21 to move relatively towards each other along the axial direction of the locking shaft 221, so as to lock or unlock the first object to the first connecting member 11, and the locking shaft 221 presses or releases the pressing of the movable end 121 to lock or unlock the second object to the second connecting member 12. The user can operate the locking wrench 222 to rotate in the locking direction. The locking wrench 222 can cause the locking shaft 221 to rotate with it. Since the locking shaft 221 and the first locking member 21 are threadedly connected, the guidance of the thread enables the first locking member 21 to move axially towards the locking shaft 221 and the locking wrench 222 to lock the first object to the first connecting member 11. On the other hand, the guidance of the thread enables the locking shaft 221 to move axially relatively towards the first locking member 21, so that the locking shaft 221 can press the movable end 121 to lock the second object and the second connecting member 12. It can be understood that during disassembly, when the user can operate the locking wrench 222 to rotate in the unlocking direction, the locking wrench 222 can cause the locking shaft 221 to rotate together. The thread guidance enables the first locking member 21 to move away from the locking shaft 221 and the locking wrench 222, thereby unlocking the first object and the first connecting member 11. And the locking shaft 221 can move axially away from the first locking member 21 to release the pressing of the movable end 121, thereby unlocking the second connecting member 12 and the second object.

[0048] Specifically, the locking wrench 222 includes a wrench 2221, a retaining member 2222, and an elastic member 2223. The wrench 2221 has a through hole 22211. One end of the locking shaft 221 protruding from the movable end 121 is received in the through hole 22211, and the wrench 2221 is in shape fit with the locking shaft 221. The retaining member 2222 is threadedly fixed to the end of the locking shaft 221 away from the first locking member 21 and is received in the through hole 22211. The elastic member 2223 is sleeved on the locking shaft 221 and is located between the retaining member 2222 and the wrench 2221. The wrench 2221 is in shape fit with the locking shaft 221, specifically an internal hexagon joint, so that the operator can drive the locking shaft 221 to rotate by rotating the wrench 2221. On the other hand, the retaining member 2222 is fixed to the locking shaft 221, and both ends of the elastic member 2223 abut against the retaining member 2222 and the wrench 2221, so that the wrench 2221 can be stably installed on the locking shaft 221. Specifically, there is also a gasket 2211 between the locking shaft 221 and the movable end 121. The first locking member 21 further includes a dental sleeve 224. The dental sleeve 224 is sleeved on the locking shaft 221 and is threadedly connected to the locking shaft 221. The setting of the dental sleeve 224 can prevent the first locking member 21 from being worn.

[0049] Please refer to Figure 6-7 , for the first locking member 21, the first connecting member 11 includes an intermediate connecting portion 113 and a connecting groove 111. The connecting groove 111 is opened in the intermediate connecting portion 113. The second connecting member 12 is connected to the intermediate connecting portion 113. The receiving groove 112 is opened in the intermediate connecting portion 113 and communicates with the connecting groove 111. The first locking member 21 can lock and install the first object in the connecting groove 111. In this embodiment, an embodiment in which the first connecting member 11 includes a connecting groove 111 is given. In this embodiment, the receiving groove 112 is opened in the intermediate connecting portion 113. When the first object slides in the connecting groove 111, a part of the structure of the first object can pass over the receiving groove 112, and the first locking member 21 can just be configured to lock the first object here. When the user operates the second locking member 22 to rotate in the locking direction, the first locking member 21 can move relatively toward the second locking member 22, so that the first locking member 21 can lock the first object in the connecting groove 111. When the user operates the second locking member 22 to rotate in the unlocking direction, the first locking member 21 can move relatively away from the second locking member 22, so that the first locking member 21 releases the locking of the first object.

[0050] In one aspect, please refer to Figure 7-8, the first locking member 21 includes a locking seat 213 and relatively arranged first and second locking portions 211 and 212. The first and second locking portions 211 and 212 are connected to the side of the locking seat 213 facing away from the second locking member 22. There is a locking space 214 between the first and second locking portions 211 and 212. The locking seat 213 is movably arranged in the receiving groove 112. The second locking member 22 can drive the locking seat 213 to move in the receiving groove 112 so that the first and second locking portions 211 and 212 can lock a first object in the locking space 214 to lock and install in the connection groove 111. Specifically, the truss beam 201 generally includes a first inclined surface 2012 and a second inclined surface 2013. The first locking portion 211 includes a third inclined surface 2111, and the second locking portion 212 includes a fourth inclined surface 2121. When the truss beam 201 is installed in the locking space 214, the user operates the second locking member 22 in the locking direction, and the first locking member 21 can move relatively towards the second locking member 22 so that the first inclined surface 2012 and the second inclined surface 2013 can respectively press against the third inclined surface 2111 and the fourth inclined surface 2121, thereby enabling the first and second locking portions 211 and 212 to lock the truss beam 201. When the user operates the second locking member 22 in the unlocking direction, the first locking member 21 can move relatively away from the second locking member 22 so that the first inclined surface 2012 and the second inclined surface 2013 can respectively release the pressing against the third inclined surface 2111 and the fourth inclined surface 2121, thereby enabling the first and second locking portions 211 and 212 to unlock the truss beam 201. The truss beam 201 can slide relative to the connection groove 111, and the user can slide the truss beam 201 down to disassemble the truss beam 201.

[0051] On the other hand, the locking seat 213 includes a mounting hole 2133. A spring 2134 is arranged in the mounting hole 2133. The spring 2134 abuts against or is connected between the locking seat 213 and the bottom of the receiving groove 112. In the locked state, the spring 2134 can tightly abut against the locking seat 213, thereby increasing the locking stability of the locking seat 213; during the unlocking process, the elastic force of the spring 2134 can assist the locking seat 213 to reset.

[0052] Finally, please refer to the figure. The middle connecting part 113 includes a middle part connecting block 1131 and a limiting shaft 1132. The accommodating groove 112 is formed in the middle part connecting block 1131. The locking seat 213 has a limiting sliding groove 2131 and a moving hole 2132. The limiting shaft 1132 is fixed to the middle part connecting block 1131 and passes through the limiting sliding groove 2131. A limiting protrusion 223 is provided at one end of the second locking member 22 away from the movable end 121. The limiting protrusion 223 is accommodated in the moving hole 2132. The limiting shaft 1132 can limit the locking seat 213 and the second locking member 22. With such a setting, the limiting sliding groove 2131 can limit the stroke of the locking seat 213. During the unlocking process, when the second locking member 22 moves relatively away from the locking seat 213, the setting of the limiting shaft 1132 can limit the limiting protrusion 223 of the second locking member 22, thereby preventing the second locking member 22 from detaching. As mentioned above, the second locking member 22 includes a locking shaft 221 and a locking wrench 222. Specifically, in this embodiment, the limiting protrusion 223 includes a limiting convex block 2232 and a connecting shaft 2231. The connecting shaft 2231 is connected to one end of the locking shaft 221 away from the locking wrench 222. The limiting convex block 2232 is connected to one end of the connecting shaft 2231 away from the locking shaft 221. The locking shaft 221 is threadedly connected to the locking seat 213. The diameter of the connecting shaft 2231 is smaller than that of the locking shaft 221. Thus, during the process of the locking shaft 221 moving relatively away from the locking seat 213, there is no structural interference between the connecting shaft 2231 and the limiting shaft 1132, and the limiting convex block 2232 can be limited by the limiting shaft 1132 to prevent the locking shaft 221 from being screwed out of the locking seat 213.

[0053] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structural transformation made under the concept of the present application using the content of the specification and drawings of the present application, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present application.
