Abstract
Description
Technical Field
[0001] This utility model belongs to the field of active component technology, and specifically relates to an installation structure and a device using the installation structure. Background Technology
[0002] Existing director cart support structures and quick-release column designs are mainly optimized for folding, storage, and convenient transportation. However, different technical solutions differ in mechanical structure, operational complexity, and functional expandability. The limitation of the trolley structure in patent CN222808126U lies in the complexity of the moving component structure, which relies on the linkage of multiple parts such as knob rotation and spring compression, potentially increasing the number of operation steps and maintenance difficulty. Patent CN220974221U provides a quick-release column structure and a director cart with a quick-release column structure. The quick-release column structure simplifies the mechanical principle while retaining expandability. However, existing solutions need to balance structural simplification, operational convenience, and functional expandability, especially addressing the usage threshold caused by complex folding mechanisms, while also meeting the needs for multi-scenario accessory compatibility. Utility Model Content
[0003] To address the aforementioned problems, the primary objective of this utility model is to provide an installation structure and a device using the installation structure, thereby resolving the technical issues of current installation structures being unable to expand to connect more accessories and having complex mechanical designs.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] This utility model provides an installation structure, including:
[0006] The support block is provided with a receiving cavity for accommodating the support column;
[0007] A latch is pivotally connected to the support block, and the latch engages with the support block to lock the support column located within the receiving cavity. The pivotal connection and engagement design between the latch and the support block allows for quick locking or unlocking of the support column within the receiving cavity, simplifying operation and improving loading and unloading efficiency.
[0008] Furthermore, the side wall of the support block is provided with a clearance groove, which is used to accommodate the lever;
[0009] When the latch is positioned within the clearance groove, it secures the support column within the receiving cavity. The latch and clearance groove work together to create a physical limit, resulting in more even force distribution during locking and preventing the support column from wobbling within the receiving cavity. By providing a clearance groove on the side wall of the support block, the latch can be completely retracted within the groove, avoiding the need for additional space, improving the overall structural compactness, and facilitating transportation or use in confined spaces.
[0010] Furthermore, it also includes:
[0011] A buffer section is disposed within the clearance groove, connected to the support block, and encloses the receiving cavity;
[0012] The latch is interference-fitted with the buffer section to lock the support column located in the receiving cavity.
[0013] The buffer section, with its interference fit to the latch, utilizes elastic deformation to generate continuous clamping force, preventing the support column from loosening under vibration or load, making it particularly suitable for bumpy transportation environments. By positioning the buffer section within the clearance groove, precise alignment between the latch and the buffer section is ensured when the latch is engaged.
[0014] Furthermore, the latch includes a connecting end and a free end; the connecting end is hinged to the support block via a rotating shaft; one end of the buffer part is connected between the connecting end and the support block; the other end of the buffer part is hinged to the support block; and the free end is used to engage with the buffer part.
[0015] Furthermore, it also includes:
[0016] A gasket is fitted between the buffer portion on the side away from the connecting end and the support block;
[0017] The connector passes sequentially through the rotating shaft, the end of the buffer portion, and the gasket, and is connected to the support block.
[0018] Furthermore, the buffer section is integrally connected to the support block. This integral molding design eliminates assembly gaps inherent in split structures and simplifies the assembly process.
[0019] Furthermore, a retaining wall is provided on the inner wall of the support block, protruding from the inner wall of the support block and distributed axially around the support block; the retaining wall divides the receiving cavity into a first receiving area and a second receiving area. The retaining wall increases axial positioning capability while providing a basic locking function between the latch and the support block. The first and second receiving areas are respectively used to accommodate the ends of the support column. Both the upper and lower ends of the mounting structure can be adapted to fit accessories such as support columns, and can meet the connection requirements of multiple accessory specifications.
[0020] This utility model also provides a device using the mounting structure, including the mounting structure as described above, and further including:
[0021] The base includes multiple layers of receiving frames, with adjacent receiving frames spaced apart.
[0022] Multiple support columns are provided on the base, and the multiple support columns are spaced apart between adjacent receiving frames;
[0023] The mounting structure is provided between the receiving frame and the supporting column.
[0024] The locking installation structure allows for quick and easy attachment of the support columns to the multi-layered storage frames of the base, enabling tool-free assembly and disassembly for convenient transportation or storage. The number of support columns can be increased or decreased as needed to accommodate storage frames of different sizes. The unlocking installation structure allows for quick removal or rotation and folding of the support columns, reducing the space occupied by the trolley when not in use and facilitating storage or transportation.
[0025] Furthermore, the first end of each of the supporting columns is disposed in the first receiving area; the second end of each of the supporting columns is disposed in the second receiving area. This design is suitable for mounting structures where accessories, such as supporting columns, can be adapted at both the upper and lower ends, and can meet the connection requirements of multiple accessory specifications.
[0026] Furthermore, it also includes:
[0027] A movable component is disposed at the bottom of the base and connected to the side of the receiving frame away from the supporting column. The movable component is designed to facilitate the movement of the device, making it suitable for scenarios with frequent site changes, such as film shooting and workshop logistics, allowing equipment or tools to be moved without manual handling.
[0028] Compared with the prior art, the beneficial effects of this application are as follows: The mounting structure includes: a support block with a receiving cavity for accommodating a support column; and a latch, pivotally connected to the support block, which engages with the support block to lock the support column located within the receiving cavity. The mounting structure uses the latch and the clearance groove to form a physical limit, resulting in more even force distribution during locking and preventing the support column from swaying within the receiving cavity. By providing a clearance groove on the side wall of the support block, the latch can be completely housed within the groove, avoiding the occupation of extra space, improving the overall structural compactness, and facilitating transportation or use in confined spaces.
[0029] The device utilizing this mounting structure includes the mounting structure itself, and further includes: a base comprising multiple layers of receiving frames spaced apart from each other; multiple supporting columns disposed on the base, each supporting column positioned between adjacent receiving frames; and the mounting structure itself connecting the receiving frames and the supporting columns. By extending the quick-release, stable, and adaptable advantages of the mounting structure to the overall device design, a high-strength, easy-to-store, and multi-scenario applicable solution is achieved, particularly suitable for professional equipment carriers requiring frequent assembly or transportation.

Detailed Implementation
[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0036] To achieve the above objectives, the technical solution of this utility model is as follows:
[0037] See Figures 1-4 As shown, this utility model provides an installation structure 10, including:
[0038] The support block 100 is provided with a receiving cavity 101, which is used to accommodate the support column 20.
[0039] The latch 200 is pivotally connected to the support block 100, and the latch 200 engages with the support block 100 to lock the support column 20 located in the receiving cavity 101.
[0040] The installation structure 10 uses a support block 100 and a latch 200, which are pivotally connected. The support block 100 has a receiving cavity 101 to accommodate the support column 20. The latch 200 is fastened to the support block 100 to lock the support column 20 within the receiving cavity 101. Thus, through the pivotal connection and latching design between the latch 200 and the support block 100, the support column 20 can be quickly locked or unlocked within the receiving cavity 101, simplifying operation and improving loading and unloading efficiency. Only two core components, the support block 100 and the latch 200, are needed for fixation, resulting in a simple mechanical structure, fewer potential failure points, and lower maintenance costs. The latching mechanism of the support block 100 and the latch 200 directly acts on the support column 10, avoiding complex linkage mechanisms such as springs and rotating parts, thus enhancing locking stability. The cavity 101 is designed to accommodate support columns 10 of different sizes. Compatibility is achieved by adjusting the latch 200 relative to the support block 100, thus expanding application scenarios. The support column 10 can be stably housed in the cavity 101, preventing shaking during transportation or use. At the same time, it does not need to be disassembled when folded, saving storage space.
[0041] Furthermore, the support block 100 has a clearance groove 102 on its side wall, which is used to accommodate the latch 200. When the latch 200 is positioned within the clearance groove 102, it is used to fasten the support column 20 within the receiving cavity 101. By providing the clearance groove 102 on the side wall of the support block 100, the latch 200 can be completely housed within the clearance groove 200, avoiding protruding parts occupying extra space, improving the overall structural compactness, and facilitating transportation or use in confined spaces. When the latch 200 is positioned within the clearance groove 102, it can directly fasten the support column 20. Users can complete the locking action without adjusting the latch position, reducing operation steps and achieving "one-click" locking. The clearance groove 102 limits the range of motion of the latch 200, preventing the latch 200 from accidentally swinging or colliding with other parts when not in operation, reducing the risk of accidental activation, and improving safety. The engagement of the latch 200 and the clearance groove 102 forms a physical limit, resulting in more even force distribution during locking and preventing the support column 20 from swaying within the receiving cavity 101. This is particularly suitable for load-bearing or trolley-moving scenarios. Therefore, based on the pivotal engagement of the support block 100 and the latch 200, the clearance groove 102 further optimizes the spatial layout and operational logic, enabling the simple structure to combine high efficiency and reliability.
[0042] Furthermore, the mounting structure 10 also includes: a buffer portion 300, which connects to the support block 100 and encloses it to form a receiving cavity 101; a latch 200 is interference-fitted with the buffer portion 300 to lock the support column 20 located within the receiving cavity 101. By adding the buffer portion 300, a flexible clamping force is provided when the latch 200 is locked, avoiding scratches or deformation of the support column 20 surface caused by rigid contact, thus extending its service life. Through the interference fit between the buffer portion 300 and the latch 200, a continuous clamping force is generated by elastic deformation, preventing the support column 20 from loosening under vibration or load, which is especially suitable for bumpy transportation environments. The buffer portion 300 can accommodate support columns 20 of different diameters, compensating for dimensional tolerances through elastic deformation, thus improving versatility. Therefore, the design of the buffer portion 300 can further optimize the reliability and protection of clamping.
[0043] Further, in a specific embodiment, the connecting end 201 of the latch 200 is hinged to the support block 100 via a rotating shaft 230; one end of the buffer portion 300 is connected between the connecting end 201 and the support block 100; the other end of the buffer portion 300 is hinged to the support block 100, and the free end 202 of the latch 200 is used to engage with the buffer portion 300. By hinged between the connecting end 201 and the support block 100 around the rotating shaft 230, the buffer portion 300 is fixedly installed between the connecting end 201 and the support block 100, and the other end of the buffer portion 300 is hinged to the support block 100, thus achieving a reasonable design of the structural relationship between the buffer portion 300, the latch 200, and the support block 100. The buffer portion 300 is preferably a rubber pad or an elastic bushing.
[0044] Furthermore, the mounting structure 10 also includes: a gasket 210, which fits between the side of the buffer portion 300 away from the connecting end 201 and the support block 100; and a connector 220, which sequentially passes through the rotating shaft 230, the end of the buffer portion 300, and the gasket 210 and connects to the inside of the support block 100. The connector 220 can fix the rotating shaft 230, the buffer portion 300, and the gasket 210 on the same side of the support block 100. The gasket 210 makes contact with the surface of the buffer portion 300 away from the connecting end 201 to protect the end of the buffer portion 300 and increase the service life of the buffer portion 300.
[0045] When it is necessary to lock the support column 20 housed in the receiving cavity 101, the free end 202 of the buckle 202 is engaged with the buffer part 300, the connecting end 201 of the buckle 202 rotates around the rotating shaft 230 and the free end 202 moves toward the buffer part 300 to squeeze the buffer part 300, thereby deforming the side of the buffer part 300 toward the receiving cavity 101 to lock the support column 20.
[0046] Furthermore, in other embodiments, instead of connecting the buffer portion 300 and the support block 100 via components, the buffer portion 300 and the support block 100 can be directly integrated. The buffer portion 300 is an elastic portion. The integrated connection of the buffer portion 300 and the support block 100 is preferably achieved by injection molding, thereby eliminating assembly gaps in a split structure design and avoiding the risk of failure due to loose bolts or aging connectors.
[0047] It should be noted that when the buffer part 300 and the support block 100 are connected by components, the buffer part 300 needs to be configured within the clearance groove 102. Alternatively, when the buffer part 300 and the support block 100 are integrally connected, the buffer part 300 is configured within the clearance groove 102. By directly configuring the buffer part 300 within the clearance groove 102, precise alignment between the latch 200 and the buffer part 300 is ensured when the latch is engaged, avoiding additional external space occupation and maintaining a simple overall structure.
[0048] Furthermore, a retaining wall 103 is provided on the inner wall of the support block 100. The retaining wall 103 protrudes from the inner wall of the support block 100 and is distributed axially around the support block 100. The retaining wall 103 protruding from the inner wall of the support block 100 forms a physical limit, preventing the support column 20 from axially shifting or rotating within the receiving cavity 101, thus ensuring stability. Moreover, the axial distribution of the retaining wall 103 can evenly transfer the load of the support column 20 to the support block 100, avoiding localized stress concentration that could lead to structural deformation. Therefore, in addition to providing a basic locking function between the latch 200 and the support block 100, the retaining wall 103 increases the axial positioning capability, extending its application to high-load scenarios.
[0049] Furthermore, the retaining wall 103 divides the receiving cavity 101 into a first receiving area 104 and a second receiving area 105, which are used to accommodate the ends of the support column 20, respectively. By dividing the receiving cavity 101 into the first receiving area 104 and the second receiving area 105 by the retaining wall 103, the ends of the support column 20 are fixed, forming a double locking point, which significantly improves the resistance to torsion and bending. Unlike the existing installation structures that are limited to unidirectional installation of the support column 20, the installation structure 10 of this application divides the receiving cavity 101 into the first receiving area 104 and the second receiving area 105 by the retaining wall 103. This is suitable for fitting accessories such as the support column 20 at both the upper and lower ends of the installation structure 10, and can meet the connection requirements of multiple specifications of accessories. Through the partitioned design of the retaining wall 103, the axial stability and adaptability of the support column 20 are solved while maintaining the simplicity of the structure. It is also particularly suitable for high-load or frequently disassembled application scenarios.
[0050] It should be noted that each mounting structure 10 includes two sets of latches 200, clearance grooves 102, buffer portions 300, gaskets 210, and connectors 220, corresponding to the first receiving area 104 and the second receiving area 105, respectively. These connectors are used to assemble the first end 21 of the support column 20 within the first receiving area 104 and the second end 22 of the support column 20 within the second receiving area 105. Thus, the mounting structure 10 is compatible with accessories such as support columns 20 at both its upper and lower ends, and meets the connection requirements of multiple accessory specifications.
[0051] Therefore, the installation structure 10 provided by this utility model, through the setting of a support block 100 and a latch 200, is pivotally connected. The support block 100 has a receiving cavity 101 to accommodate the support column 20, and the latch 200 is fastened to the support block 100 to lock the support column 20 configured in the receiving cavity 101. Thus, through the pivotal connection and fastening design of the latch 200 and the support block 100, the support column 20 can be quickly locked or unlocked in the receiving cavity 101, simplifying the operation steps and improving the loading and unloading efficiency. Only two core components, the support block 100 and the latch 200, are needed to complete the fixation, resulting in a simple mechanical structure, reducing failure points, and lowering maintenance costs. The fastening method acts directly on the support column 10, avoiding complex linkage mechanisms such as springs and rotating parts, and enhancing locking stability. The design of the receiving cavity 101 can adapt to support columns 10 of different sizes, and compatibility can be achieved by adjusting the fastening force of the latch 200 relative to the support block 100, expanding the application scenarios. The support column 10 can be stably housed in the receiving cavity 101 to prevent shaking during transportation or use, and it does not need to be disassembled when folded, saving storage space.
[0052] This utility model also provides a device using the mounting structure, including the mounting structure 10 as described above, and further including: a base (not labeled) and multiple supporting columns 20. The base includes multiple receiving frames 30, with adjacent receiving frames 30 spaced apart; multiple supporting columns 20 are disposed on the base, with the multiple supporting columns 20 spaced apart between adjacent receiving frames 30; the mounting structure 10 is provided between the receiving frames 31 and the supporting columns 20.
[0053] This application provides a device utilizing this mounting structure, which combines multi-layer receiving frames 30 with support columns 20. Specifically, the support columns 20 are quickly fixed between the multi-layer receiving frames 30 on the base using support blocks 100 and latches 200 of the mounting structure 10, without the need for bolts or tools, achieving tool-free assembly and disassembly, facilitating transportation or storage. The number of support columns 20 can be increased or decreased as needed to accommodate receiving frames 30 of different sizes. Furthermore, multiple support columns 20 are evenly distributed between adjacent receiving frames 30, forming a stable three-dimensional frame, improving the overall load-bearing capacity of the device and preventing deformation under single-point stress. Through the multiple structural design of the buffer section 300, the first receiving area 104, and the second receiving area 105, it is ensured that the support columns 20 will not loosen under movement or bumpy conditions. By unlocking the latches 200, the support columns 20 can be quickly removed or rotated and folded, reducing the space occupied by the trolley when not in use, facilitating storage or transportation.
[0054] Furthermore, the first end 21 of each support column 20 is disposed in the first receiving area 104; the second end 22 of each support column 20 is disposed in the second receiving area 105. The first end 21 is specifically the bottom end of the support column 20, and the second end 22 is specifically the top end of the support column 20. The receiving cavity 101 is divided by the retaining wall 103 to form the first receiving area 104 and the second receiving area 105, which is suitable for fitting accessories such as support columns 20 at both the upper and lower ends of the mounting structure 10, and can meet the connection requirements of multiple specifications of accessories. Since both ends of the support column 20 are fixed, a double-point constraint is formed to prevent the support column 20 from axial movement or rotation when the trolley moves or is loaded, thereby improving the rigidity of the overall frame. It is especially suitable for heavy equipment transportation or movement on uneven roads, avoiding structural instability due to loosening on one side.
[0055] Furthermore, an apparatus using this mounting structure further includes a movable component 40, disposed at the bottom of the base and connected to the side of the receiving frame 30 away from the supporting columns 20. When the receiving frame 30 is a square frame, four supporting columns 20 and four sets of mounting structures 10 are arranged between adjacent receiving frames 30, with the supporting columns 20 or mounting structures 10 located at the four corners of the receiving frame 30. The apparatus using this mounting structure is preferably a trolley, and the movable component 40 is preferably a wheel assembly. The design of the movable component 40 makes the apparatus easy to move and is suitable for scenarios with frequent site changes, such as film shooting and workshop logistics, allowing equipment or tools to be transferred without handling.
[0056] This application provides a device that utilizes this mounting structure. By extending the advantages of the mounting structure 10—quick disassembly, stability, and adaptability—to the overall device design, it achieves a high-strength, easy-to-store, and multi-scenario applicable trolley solution, especially suitable for professional equipment carriers requiring frequent assembly or transportation. Trolleys using this mounting structure are suitable for director's carts, tool carts, logistics carts, etc., and can carry equipment, toolboxes, or filming equipment, meeting the needs of film and television, industrial, and warehousing fields.
[0057] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
