Description

Technical Field

[0001] This utility model relates to the field of accessories technology, specifically to a linkage locking assembly, truss, and workstation. Background Technology

[0002] In daily life, mobile workstations are a type of auxiliary vehicle, generally suitable for scenarios such as work and outdoor activities. For example, users can use mobile workstations to load photographic accessories in some shooting scenarios.

[0003] In existing technologies, mobile workstations typically include multiple support columns and multi-level storage platforms connected by these columns. The bottom storage platform is equipped with wheels for easy movement. Each storage platform can be connected to extension accessories, such as trusses, via the support columns. The trusses and support columns form a truss, which has corresponding device interfaces, allowing for the installation of photographic accessories on the mobile workstation. Generally, one of the support column or the truss is the primary component, and the other is the secondary component. These two components are connected by a connecting adapter. One end of the adapter locks the support column with a locking device, and the other end locks the truss with another locking device. Using such a connecting adapter to connect the truss and support column requires at least two locking operations, making it relatively inconvenient to use. Utility Model Content

[0004] This utility model provides a linkage locking assembly, truss, and workstation to achieve convenient and quick connection between a first object and a second object.

[0005] In a first aspect, the linkage locking assembly provided by this utility model is used to connect a first object and a second object, comprising:

[0006] The clamping assembly includes a first clamping member and a second clamping member, the first clamping member and the second clamping member forming a receiving space for accommodating the first object, one end of the first clamping member being connected to the second clamping member, and the other end being a movable end relative to the second clamping member, an opening being formed between the movable end and the second clamping member to allow the first object to enter and exit the receiving space;

[0007] A locking assembly includes a first locking portion and a second locking portion. The second locking portion is movably disposed on a second clamping member. The first locking portion is pivotally connected to the second locking portion. The first locking portion has a first position and a second position during its pivot stroke. In the first position, the first locking portion can lock the movable end, causing the clamping assembly to clamp the first object and drive the second locking portion to lock the second object onto the second clamping member. In the second position, the first locking portion avoids the movable end, allowing the opening to open and close.

[0008] In one technical solution, the linkage locking assembly further includes an elastic reset member disposed on the second clamping member, the elastic reset member being able to drive the first locking part to reset to the first position when the first locking part is in the second position.

[0009] In one technical solution, the first locking part includes a connecting rod, one end of which is a hinged end, and is hinged to the second locking part through the hinged end to realize that the first locking part is swayably connected to the second locking part. The elastic reset member is a spring, one end of which is fixed to the second clamping member, and the other end passes around from the side of the hinged end away from the first clamping member and bends toward the first locking part to form a bent part. The bent part is located on the side of the first locking part facing the second position to drive the first locking part to reset to the first position.

[0010] In one technical solution, the second locking part includes a locking block and a fixing pin. The locking block is used to cooperate with the second clamping member to lock the second object. The fixing pin is disposed on the locking block. The hinge end cooperates with the fixing pin to form a hinge structure. One end of the spring can stop the hinge end to stop the fixing pin and thus stop the locking block.

[0011] In one technical solution, the hinged end of the connecting rod and the surface that mates with the spring are arc-shaped surfaces, and the bent portion is an arc-shaped bent structure.

[0012] In one technical solution, the second clamping member has a locking groove for accommodating the second object, the second locking part is embedded in a mounting groove provided on the second clamping member, the mounting groove communicates with the locking groove, the bottom of the locking groove has a recess, the second locking part has a groove, the connecting rod extends into the groove and is hinged to the second locking part, one end of the spring is fixed in the recess, and the other end extends into the groove.

[0013] In one technical solution, the first locking portion further includes a clamping member, which is threadedly connected to the connecting rod so that the connecting rod and the clamping member can move relative to each other by rotating the clamping member, so that the first locking portion and the second locking portion can move relative to each other. The clamping member has a clamping structure that can clamp and engage with the movable end. The second locking portion has an insertion cavity for inserting the second object, so that the second locking portion can drive the second object to move, thereby locking the second object by pressing the second object onto the second clamping member.

[0014] In one technical solution, the first locking portion and the second locking portion are configured to move relative to each other. By moving the second locking portion, the second object can be locked onto the second clamping member. By moving the first locking portion, the movable end can be locked, so that the clamping assembly clamps the first object.

[0015] In one technical solution, the first locking part includes a connecting rod and a clamping member. The connecting rod is hinged to the second locking part to enable the first locking part to be oscillatingly connected to the second locking part. The clamping member is threadedly connected to the connecting rod so that the connecting rod and the clamping member can move relative to each other by rotating the clamping member, thereby enabling the first locking part and the second locking part to move relative to each other. The clamping member has a clamping structure that can clamp and engage with the movable end.

[0016] Secondly, this utility model provides a truss, which includes a support column as a first object and a truss beam as a second object. The truss beam is connected to the support column by a linkage locking assembly, which is the linkage locking assembly in the above-mentioned technical solutions.

[0017] Thirdly, this utility model provides a workbench, the workstation including a truss and multiple storage platforms, the truss being the truss in the above-mentioned technical solutions, and the multiple storage platforms being arranged in layers supported by the support columns of the truss.

[0018] The beneficial effects of this utility model are as follows:

[0019] When using the linkage locking assembly of this utility model to connect the first object and the second object, the first locking part can be moved to the second position first. At this time, the opening can be opened by the movable end of the first clamping member relative to the second clamping member, so that the first object can easily enter the receiving space. Compared with the clamping assembly being sleeved on the first object, this structure of the utility model can improve the convenience of the first object entering the receiving space. After the first object enters the receiving space, the first locking part is moved back to the first position. Since the first locking part and the second locking part are connected, the two parts are linked and can lock the first object and the second object simultaneously, improving the efficiency and convenience of connecting the first object and the second object.

[0036] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0037] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0038] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0039] In an embodiment of this utility model, in the truss of the workstation, the truss beams and support columns are connected by a linkage locking assembly. In the linkage locking assembly, the first locking part can swing relative to the second locking part, and the movable end of the first clamping member can move relative to the second clamping member, forming an opening communicating with the accommodating space between the movable end and the second clamping member. In use, the first locking part is moved to the second position, allowing the first object to enter the accommodating space through the opening, and then the first locking part is moved back to the first position. Since the first locking part and the second locking part are linked, the first locking part and the second locking part can simultaneously lock the first object and the second object, ensuring the convenience and speed of connecting the first object and the second object.

[0040] An embodiment of the workstation in this utility model:

[0041] In one embodiment, please refer to Figure 1 The workstation includes a truss 10 and multiple storage platforms 20, which are arranged in layers. Wheels 30 are installed under the bottom storage platform 20, making the workstation a mobile workstation. In other embodiments, the workstation may not be equipped with wheels 30 and can be used as a workstation for long-term use in a certain location. Of course, such a workstation can also be moved, but the movement method is transport.

[0042] Please refer to Figure 1 and Figure 2 The truss 10 includes support columns 11, truss beams 12 and linkage locking components 13. The two ends of the truss beams 12 are connected to the two support columns 11 through two sets of linkage locking components 13. That is, the support columns 11 are the first object and the truss beams 12 are the second object. The two objects are connected by the linkage locking components 13.

[0043] The truss 12 has a camera interface for connecting external camera accessories, including but not limited to NATO interface, threaded interface, Arca quick-release plate, and cold shoe interface. A truss 12 may have one or more interfaces of a single type, or multiple interfaces of different types. The specific structure of the truss 12 is prior art and will not be described in detail here.

[0044] The support columns 11 are cylindrical and arranged according to the positional relationship of the four vertices of a rectangle. The two storage platforms 20 are arranged in layers, supported by the four support columns 11. Among them, two support columns 11 extend upwards from the uppermost storage platform 20, and a truss beam 12 connects the two support columns 11. As those skilled in the art will understand, the cross-sectional shape of the support columns 11 can be changed, such as being rectangular, elliptical, pentagonal, etc., and can be solid or hollow columns.

[0045] Please refer to the structure of the linkage locking assembly 13. Figure 3 It includes a clamping assembly and a locking assembly. The clamping assembly includes a first clamping member 131 and a second clamping member 132, which together form a receiving space 133 for accommodating the first object, i.e., the support column 11. Since the support column 11 is a cylindrical structure, the two opposing sides of the two clamping members have arc-shaped recesses, which together form a channel-type receiving space 133 with a circular cross-section. The reference numerals pointing to the spatial structure in the figure are dashed lines.

[0046] In other embodiments, provided that the two clamping members can clamp the first object, a recess can be provided on only one of the two opposing sides of the two clamping members, while the other side is designed as a planar structure. In this case, the recess can have a deeper depth to ensure that the two clamping members can reach a closed state.

[0047] One end of the first clamping member 131 is connected to the second clamping member 132, and the other end is a movable end 134 relative to the second clamping member 132. An opening 135 is formed between the movable end 134 and the second clamping member 132, allowing the support column 11 to enter and exit the receiving space 133 through the opening 135. In this way, the support column 11 enters and exits the receiving space 133 radially. Compared with the structure of the clamping assembly, which can only be fitted onto the support column 11 along the axial direction, the structure of the clamping assembly in this utility model is more convenient for its combination and installation with the support column 11, improving the ease of installation of the truss beam 12 on the support column 11.

[0048] Regarding the connection method between one end of the first clamping member 131 and the second clamping member 132, in one embodiment, one end of the first clamping member 131 is hinged to the second clamping member 132, and the axis of the hinge shaft extends vertically. In other embodiments, a connecting ring can be provided on one of the corresponding ends of the first clamping member 131 and the second clamping member 132, and a connecting hook can be provided on the other end. The connection between the two can be achieved by hooking the connecting hook into the connecting ring. Of course, if the truss beam 12 is not frequently disassembled and assembled, the corresponding ends of the first clamping member and the second clamping member can be integrally formed and connected. Specifically, the connection transition between the first clamping member and the second clamping member is made thinner to make it easy to deform, so as to ensure that the movable end of the first clamping member can move easily.

[0049] Please refer to Figure 4 and Figure 5 The locking assembly has a first locking part and a second locking part. The second locking part is movably disposed on the second clamping member 132, while the first locking part is swayably connected to the second locking part, so that the first locking part has a first position and a second position in the swing stroke. In the first position, the first locking part can press and cooperate with the movable end 134 to lock the movable end 134 of the first clamping member 131, so that the clamping assembly clamps the support column 11, and at the same time drives the second locking part to move, locking the truss beam 12 on the second clamping member 132. In the second position, the first locking part avoids the movable end 134, so that the first clamping member 131 can be movably opened and closed to realize the closure of the opening 135, so that the support column 11 can enter and exit the accommodating space 133 through the opening 135.

[0050] Please refer to Figure 6 The second clamping member 132 has a locking groove 136 for accommodating and locking the truss beam 12. The locking groove 136 is located on the side of the second clamping member 132 opposite to the first clamping member 131. The cross-sectional shape of the locking groove 136 is adapted to the cross-sectional shape of the part of the truss beam 12 that connects and engages with the linkage locking assembly 13, so that the truss beam 12 cannot be dislodged from the locking groove 136. In one embodiment, the cross-section of the part of the truss beam 12 that connects and engages with the linkage locking assembly 13 is hexagonal. Therefore, the locking groove 136 is a narrow-mouthed groove with a large cavity. By blocking the opening edge of the groove, the part of the truss beam 12 that connects to the linkage locking assembly 13 can be prevented from dislodging from the locking groove 136.

[0051] The second clamping member 132 is also provided with a mounting groove 137, which communicates with the locking groove 136. The second locking part includes a locking block 138 disposed in the mounting groove 137, which can slide within the mounting groove 137. Please refer to [reference needed]. Figure 9The locking block 138 has a groove 139, which is open on three sides, having an opening facing the first locking part and a groove bottom 1310 opposite to the opening. A mounting cavity for inserting the truss beam 12 is provided on the side of the locking block 138 facing away from the first locking part, allowing the second locking part to move the truss beam 12 and press and lock it onto the second clamping member 132. In one embodiment, the mounting cavity is a groove structure 1311 with the same shape as the locking groove 136. Thus, in use, the truss beam 12 passes through the locking groove 136 and the groove structure 1311 on the locking block 138. By moving the locking block 138 into the mounting groove 137, the truss beam 12 can be locked onto the second clamping member 132. The second locking part also has a fixing pin 1312 fixed to the locking block 138, which passes through the groove 139. In other embodiments, the mounting cavity can also be a circumferentially closed through hole. Those skilled in the art will also understand that the locking groove 136 may not be provided on the second clamping member, and the truss beam 12 is pressed against the plane at the end of the second clamping member to achieve locking under the action of the second locking part.

[0052] Please refer to Figure 4 and Figure 5 The first locking part includes a connecting rod 1313 and a clamping member 1314. One end of the connecting rod 1313 is a hinged end, which is rotatably connected to the fixing pin 1312 to form a hinged structure, realizing the hinged connection between the connecting rod 1313 and the locking block 138, thereby realizing the swing connection of the first locking part on the second locking part. Please refer to [reference needed]. Figure 6 and Figure 7 The second clamping member 132 has a channel 1315 communicating with the mounting groove 137. The connecting rod 1313 extends through the channel 1315 and has a threaded structure at the extended end. The clamping member 1314 is threadedly connected to the connecting rod 1313. In this way, the first connecting assembly and the second connecting assembly are configured to move towards each other. Specifically, by rotating the clamping member 1314, the clamping member 1314 can move along the connecting rod 1313 toward the locking block 138. When the clamping member 1314 reaches the position to cooperate with the first clamping member 131, the locking block 138 can be pulled in the opposite direction by the connecting rod 1313 toward the clamping member 1314, so that the first locking part and the second locking part can move towards each other, realizing the linkage of the two parts of the locking assembly.

[0053] In other embodiments, the connecting rod 1313 may also be connected to the second locking portion via a ball joint connection structure.

[0054] Please refer to Figure 8In order to facilitate the cooperation between the clamping member 1314 and the first clamping member 131, a notch structure 1316 is provided at the movable end of the first clamping member 131. When the first locking part moves to the first position, the notch structure 1316 can avoid the connecting rod 1313. After the first locking part reaches the first position, the connecting rod 1313 is located in the notch structure 1316.

[0055] Please refer to Figure 11 The clamping member 1314 has a cylindrical structure, with an internal thread at one end for threaded connection with the connecting rod 1313. The outer circumferential surface of the cylindrical portion of the clamping member 1314 also has an annular flange 1317. The clamping member 1314 further includes a washer 1318 disposed on the side of the annular flange 1317 facing the second locking portion. The washer constitutes a clamping structure of the clamping member 1314 for clamping and engaging with the movable end 134. To prevent the washer 1318 from falling off, an anti-disengagement ring 1319 is also provided on the cylindrical portion of the clamping member 1314 to constrain the washer 1318 between the annular flange 1317 and the anti-disengagement ring 1319. During operation, the clamping member 1314 clamps the edge of the notch structure 1316 through the washer 1318.

[0056] In other embodiments, the connecting rod can also be a two-section structure: a rigid section and a flexible section. One end of the rigid section is threaded into the clamping member 1314, and the other end is connected to the flexible section. The end of the flexible section away from the rigid section is fixedly connected to the second locking part. The flexible shape allows the first locking part to swing relative to the second locking part. To ensure the reliability of the locking state of the locking assembly, the flexible section can be a rubber rod containing steel wire, allowing it to be bent and deformed but not stretched in the length direction. This ensures that the first and second locking parts will not accidentally move in opposite directions due to the extension of the flexible section, affecting the locking effect.

[0057] To facilitate the rotation of the clamping member 1314, the clamping member 1314 has an external hexagonal structure 1329 located on the side of the annular flange 1317 facing away from the gasket 1318. The locking assembly also includes a wrench 1320 sleeved on the clamping member 1314. The wrench 1320 has an internal hexagonal structure. Through the cooperation between the internal hexagonal structure and the external hexagonal structure 1329, the clamping member 1314 can be driven to rotate by the wrench 1320.

[0058] In one embodiment, the wrench 1320 is elastically and floatingly mounted on the clamping member 1314. Specifically, the cylindrical portion of the clamping member 1314 has a mounting section 1321 extending into the wrench. The cylindrical structure of the wrench 1320 is fitted onto the mounting section 1321 and the outer hexagonal structure 1329. An inner flange 1322 is provided on the inner wall of the cylindrical structure of the wrench 1320. A retaining member 1323 is threaded onto the end of the mounting section 1321. A spring 1324 is fitted onto the outside of the mounting section 1321 of the clamping member 1314. The two ends of the spring 1324 abut against the retaining member 1323 and the inner flange 1322, respectively. In this way, the wrench 1320 can be elastically and floatingly mounted on the clamping member 1314, improving the ease of installation of the wrench 1320 on the clamping member 1314.

[0059] Please refer to Figure 9 and Figure 10 The locking block 138 is also provided with a spring receiving groove 1325 on the end face facing the first locking part. A return spring 1330 is placed in the spring receiving groove 1325. The other end of the return spring 1330 abuts against the bottom of the mounting groove 137. When the truss beam 12 is unlocked, the return spring 1330 can drive the locking block 138 to reset and release the locking block 138 from locking the truss beam 12.

[0060] The linkage locking assembly also includes a resilient reset element; please refer to [link / reference needed]. Figure 4In one embodiment, the elastic reset member is a spring 1326. A recessed groove 1327 is located at the bottom of the locking groove 136. The recessed groove 1327 communicates with the mounting groove 137 and corresponds to the groove 139 on the locking block 138. One end of the spring 1326 is fixed in the recessed groove 1327 by a screw, and the other end extends into the groove 139 of the locking block 138. The end of the spring 1326 extending into the groove 139 passes around the hinge end of the connecting rod 1313 to the side facing away from the first clamping member 131, that is, it passes between the hinge end of the connecting rod 1313 and the bottom of the groove 1310, and bends towards the first locking portion to form a bent portion 1328. The spring plate 1326 stops the second locking part at the hinge end. The spring plate 1326 cooperates with the return spring 1330 in the spring receiving groove 1325 to prevent the second locking part from wobbling in the unlocked state, reducing the protrusion of the second locking part and preventing misalignment between the groove structure 1311 and the locking groove 136, which would affect the installation of the truss beam 12. Simultaneously, during assembly, before the clamping member 1314 is installed on the connecting rod 1313, or when the wrench 1320 rotates and causes the clamping member 1314 to disengage from the connecting rod 1313, the spring plate 1326 prevents the locking block 138 from dislodging from the mounting groove 137. The bent portion 1328, located on the side of the connecting rod 1313 facing the second position, can drive the first locking part to return to the first position. Specifically, the second locking part also has a fixing pin 1312 fixed on the locking block 138. The hinge end is rotatably connected to the fixing pin 1312 to form a hinge structure, realizing the hinge connection between the connecting rod 1313 and the locking block 138. In this article, the fixing pin 1312 is connected to the locking block 138, and the spring 1326 is located between the fixing pin 1312 and the locking block 138. The spring 1326 stops the fixing pin 1312, thereby stopping the locking block 138 to limit the locking block 138.

[0061] In other embodiments, the elastic reset member may be used only to drive the first locking portion to reset, and no longer to block the second locking portion. In this case, the elastic reset member may be a spring provided on the second clamping member, with one end of the spring engaging with the connecting rod 1313. When the first locking portion is in the second position, the spring is compressed by the connecting rod 1313 to provide a reset force toward the first position for the first locking portion.

[0062] In order to reduce wear between the connecting rod 1313 and the elastic reset member, in one embodiment, the surface on which the connecting rod 1313 mates with the spring 1326 is an arc-shaped surface, and the bending portion 1328 is specifically an arc-shaped bending structure.

[0063] The first locking part and the second locking part may not be configured to move relative to each other. The first locking part can only swing relative to the second locking part. In this case, a guide slope is provided between the first clamping member and the pressing member. When the first locking part swings to the first position, under the guidance of the guide slope, the first locking part moves away from the truss 12 with the second locking part. When the first locking part moves to the first position, the first locking part presses the movable end 134 of the first clamping member 131, so that the clamping assembly clamps the support column 11. The second locking part simultaneously locks the truss 12 onto the second clamping member 132.

[0064] This utility model also relates to a truss, which has the same structure as the truss in the above-described workstation embodiments, and will not be described in detail here.

[0065] This utility model also relates to a linkage locking component, which has the same structure as the linkage locking component in the above-mentioned workstation embodiments, and will not be described in detail here.

[0066] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.

The linkage locking assembly as described in claim 2, characterized in that, The first locking part includes a connecting rod, one end of which is a hinged end, and is hinged to the second locking part through the hinged end to realize that the first locking part is swayably connected to the second locking part. The elastic reset member is a spring, one end of which is fixed to the second clamping member, and the other end passes around from the side of the hinged end away from the first clamping member and bends toward the first locking part to form a bent part. The bent part is located on the side of the first locking part facing the second position to drive the first locking part to reset to the first position.

4. The linkage locking assembly as described in claim 3, characterized in that, The second locking part includes a locking block and a fixing pin. The locking block is used to cooperate with the second clamping member to lock the second object. The fixing pin is disposed on the locking block. The hinge end cooperates with the fixing pin to form a hinge structure. One end of the spring can stop the hinge end to stop the fixing pin and thus stop the locking block.

5. The linkage locking assembly as described in claim 3, characterized in that, The hinged end of the connecting rod has an arc-shaped surface that mates with the spring, and the bent portion has an arc-shaped bent structure.

6. The linkage locking assembly as described in claim 3, characterized in that, The second clamping member has a locking groove for accommodating the second object. The second locking part is embedded in the mounting groove provided on the second clamping member. The mounting groove communicates with the locking groove.
