[0038] Refer to Figures 1 to 4 , Figure 1 , which is a schematic structural diagram of the support leg assembly 10 in an embodiment of the present utility model. Figure 2 , which is a side view of the support leg assembly in an embodiment of the present utility model. Figure 3 is Figure 2 the sectional view at A-A in Figure 4 is Figure 2 the enlarged view at B in

[0039] An embodiment of the present utility model provides a support leg assembly 10 for a photography support frame. The support leg assembly 10 includes:

[0040] A support assembly 100, the support assembly 100 at least includes a first sleeve 102 and a second sleeve 104 sleeved with the first sleeve 102. The second sleeve 104 can move along the inner wall of the first sleeve 102 under the action of an external force;

[0041] The first locking assembly 110, the first locking assembly 110 includes a fixed seat 112 and a locking member 116. The fixed seat 112 is installed at one end of the second sleeve 104 extending into the first sleeve 102. There is a gap 112a between the outer wall of the fixed seat 112 and the inner wall of the first sleeve 102, and a threaded hole 112b is provided in the middle; the locking member 116 includes a connecting sleeve 115 threadedly connected to the fixed seat 112 and a locking member 116 connected to the connecting sleeve 115. The locking member 116 is partially inserted into the gap 112a;

[0042] The actuating rod 200, the actuating rod 200 extends into the connecting sleeve 115 and is used to drive the connecting sleeve 115 to rotate.

[0043] The support foot assembly 10 proposed in this embodiment is an important part of the photographic support frame and can be flexibly applied to a handheld monopod or a ground tripod. Specifically, if one support foot assembly 10 is used, it can be connected to the receiving seat of the photographic support frame to form a handheld monopod, or multiple support foot assemblies 10 can be combined to form a stable tripod. Whether these support frames are used for handheld or ground placement, they can carry various devices, such as cameras or auxiliary equipment such as lighting equipment.

[0044] The support assembly 100 in this embodiment not only provides a basic support function but also has a telescopic function to meet the needs of different heights. The support assembly 100 is at least composed of two sleeves, namely the first sleeve 102 and the second sleeve 104. Usually, the first sleeve 102 is used as a fixed sleeve and is connected to the receiving seat of the support frame. The second sleeve 104 partially extends into the first sleeve 102. Under the action of an external force, the second sleeve 104 can move relative to the first sleeve 102. This external force can be applied by the user or due to the action of gravity, especially when a counterweight is provided at one end of the second sleeve 104 away from the first sleeve 102, the gravity effect can be enhanced.

[0045] It should be noted that the inner diameter of the first sleeve 102 is larger than the outer diameter of the second sleeve 104 to ensure smooth telescoping between the two. Regarding material selection, the first sleeve 102 and the second sleeve 104 can use metal materials such as aluminum alloy or steel, or other lightweight and high-strength materials, such as carbon fiber. When the second sleeve 104 moves to the desired position, it needs to be locked with the first sleeve 102 to prevent the position from changing. For this purpose, the first locking assembly 110 is used for locking. The first locking assembly 110 includes a fixed seat 112 and a locking member 116. The fixed seat 112 is installed at one end of the second sleeve 104 extending into the first sleeve 102, and the locking member 116 is movably connected to the fixed seat 112 (for example, through a screw connection) to achieve the locking or unlocking function.

[0046] When using the support foot assembly 10 of this embodiment for photographic support, first, apply an external force to move the second sleeve 104 along the inner wall of the first sleeve 102 and adjust it to the required height. At this time, the user can use the first locking assembly 110 to lock the first sleeve 102 and the second sleeve 104.

[0047] During the locking process, insert the moving rod 200 into the connecting sleeve 115 and connect it to the connecting sleeve 115 movably. Since the connecting sleeve 115 is threadedly connected to the base, when the moving rod 200 rotates, the connecting sleeve 115 will move towards the fixed seat 112 in the approaching direction, so that the locking member 116 is partially inserted into the gap 112a between the outer wall of the fixed seat 112 and the inner wall of the first sleeve 102, generating frictional force to lock the positional relationship between the two. In this way, the support assembly 100 can be stably positioned at the set position and provide firm support.

[0048] When the user needs to adjust the height or store the support foot assembly 10, drive the connecting sleeve 115 away from the fixed seat 112 with the moving rod 200, thereby releasing the locked state between the first sleeve 102 and the second sleeve 104, enabling the second sleeve 104 to slide freely to a new position for height adjustment or convenient storage. In this way, the user can easily adjust the height and, in the case of frequent height adjustment, greatly improve the operation efficiency.

[0049] In the technical solution of this embodiment, the support assembly 100 at least includes a first sleeve 102 and a second sleeve 104 partially extending into the first sleeve 102. The second sleeve 104 can move relative to the first sleeve 102 under the action of an external force to achieve rapid height adjustment. When adjusted to the appropriate height, drive the locking member 116 with the moving rod 200 to make it fill and tightly press the gap 112a between the outer wall of the fixed seat 112 and the inner wall of the first sleeve 102, thereby generating frictional force between the two to lock the positions of the two sleeves. When unlocking, drive the locking member 116 with the moving rod 200 to withdraw from the gap 112a between the outer wall of the fixed seat 112 and the inner wall of the first sleeve 102, thereby releasing the locked state. The cooperation between the first locking assembly 110 and the moving rod 200 makes the height adjustment and locking simple and convenient, avoiding complex mechanical structures, with easy operation and simplified steps.

[0050] Continue to refer to Figure 4 , in this embodiment, a card slot 115a is provided at one end of the connecting sleeve 115, and the end of the locking member 116 that does not extend into the gap 112a is connected to the card slot 115a.

[0051] In this embodiment, the formation of the card slot 115a ensures that when driving the locking member 116 into the gap 112a between the outer wall of the fixed seat 112 and the inner wall of the first sleeve 102, the connecting sleeve 115 can stably drive the locking member 116. Conversely, when the locking member 116 exits from the gap 112a, it can also remain stable. This design effectively prevents the possible failure of the locking member 116 during operation, ensuring that the locking and unlocking processes are smooth and reliable. Specifically, the locking member 116 is arranged in a sleeve shape, its outer wall is in close contact with the first sleeve 102, a part of its inner wall is inserted into the gap 112a, and the inner wall can be in close contact with the outer wall of the fixed seat 112.

[0052] The locking member 116 can be made of an elastic material, such as rubber or polyurethane. The advantage of using an elastic material is that during the installation of the locking member 116, the elastic material can undergo appropriate deformation, making it easier to assemble the locking member 116 onto the connecting sleeve 115 to ensure a tight fit. The elastic material can also improve the contact quality between the locking member 116 and the fixed seat 112 and the first sleeve 102, providing stronger friction force during locking, thereby enhancing the stability of the overall device.

[0053] By providing the card slot 115a on the connecting sleeve 115 and using the elastic locking member 116, this embodiment realizes reliable control of the locking member 116 during the locking and unlocking processes, preventing loosening or failure during use. The application of the elastic material not only simplifies the assembly process but also improves the locking effect, making the support assembly 100 more stable and reliable during height adjustment at different levels, suitable for photographic needs in various usage environments.

[0054] Refer to Figure 5 and Figure 6 , Figure 5 is the structural exploded view of the support leg assembly 10 in an embodiment of the present utility model, Figure 6 is Figure 5 the enlarged view at D in

[0055] In this embodiment, the outer wall of the fixed seat 112 has a taper.

[0056] Specifically, the portion of the fixing seat 112 exposed outside the second sleeve 104 is designed to be conical, and a conical hole is also formed inside the locking sleeve. The reason for designing the fixing seat 112 to be conical is that when the locking operation is performed, the fixing seat 112 with a taper can better guide the locking member 116 to smoothly enter the gap 112a between the fixing seat 112 and the inner wall of the first sleeve 102. In other words, during the locking process, the conical fixing seat 112 can act as a guide to allow the locking member 116 to enter the correct position along the direction of the cone surface, thereby reducing the resistance during installation and ensuring the accuracy of positioning. At the same time, the conical hole of the locking sleeve and the conical structure of the fixing seat 112 are adapted to each other, ensuring that the two can fit closely during locking, thereby improving the locking efficiency and stability. Through the cooperation of the conical fixing seat 112 and the tapered hole locking sleeve, the locking member 116 can enter the gap 112a more smoothly, avoiding the jamming or misalignment problems that may occur during the locking process.

[0057] Continue reading Figure 6 In this embodiment, the locking member 116 is circumferentially structured with a plurality of openings 116b.

[0058] In this embodiment, the locking member 116 may be made of elastic material and have an opening 116b formed in its circumferential direction. The opening 116b is designed so that the locking member 116 can be unfolded under the abutment of the fixing seat 112, so as to better contact the inner wall of the first sleeve 102 and further increase the friction. This design ensures that in the locked state, the abutting ring can give full play to its elastic characteristics, and through close contact with the inner wall of the first sleeve 102, the overall friction is increased, thereby making the support structure more stable.

[0059] See also Figure 7 and Figure 8 In this embodiment, a through hole 115b is formed in the middle of the connecting sleeve 115, so that the movable rod 200 passes through the through hole 115b. Specifically, the through hole 115b is arranged in a polygonal shape, so that the shape and size of the movable rod 200 are adapted to the through hole 115b.

[0060] In this embodiment, the actuating rod 200 is polygonal, specifically, it can be a triangle, a quadrilateral or a hexagon, etc. A polygonal through hole 115b matching the shape of the actuating rod 200 is penetrated through the middle of the connecting sleeve 115, so that the actuating rod 200 can be firmly inserted into the connecting sleeve 115 and effectively transmit the rotational power.

[0061] The reason for adopting the polygonal structure is to enable the driving rod 200 to achieve efficient power transmission when driving the connecting sleeve 115 to rotate, preventing sliding and power loss. At the same time, the matching design of the polygonal through hole 115b and the polygonal driving rod 200 also allows the connecting sleeve 115 to move freely in the axial direction, which is crucial for the depth locking of the first sleeve 102 and the second sleeve 104. By allowing axial movement while maintaining rotational power transmission, the support structure can flexibly perform height adjustment and locking operations.

[0062] The beneficial effect of this design is that the power transmission reliability during rotation is ensured and energy loss is reduced through the polygonal matching between the driving rod 200 and the connecting sleeve 115. At the same time, since this structure retains the possibility of axial movement, it is suitable for application scenarios that require frequent height adjustment, improving the overall usability and structural stability.

[0063] Continue to refer to Figure 5 , in this embodiment, the support assembly 100 includes a plurality of first sleeves 102 and second sleeves 104 that are sleeved in sequence. Specifically, the support assembly 100 may further include a third sleeve, at least a part of the third sleeve extends into the second sleeve 104, and the third sleeve can move relative to the second sleeve 104 under an external force;

[0064] And a second locking assembly, provided at one end of the third sleeve extending into the second sleeve 104, and the second locking assembly is configured to be linked with the first locking assembly 110.

[0065] In this embodiment, a sleeve, that is, the third sleeve, is added to the support assembly 100. At least a part of the third sleeve extends into the second sleeve 104, and it can move freely relative to the second sleeve 104 under an external force. By adding the third sleeve, the possibility of height adjustment of the support assembly 100 is further increased, enabling the user to more flexibly adjust the height of the support. Of course, in addition to the third sleeve, the support assembly 100 can continue to be increased, such as a fourth sleeve, a fifth sleeve, etc., to meet the height adjustment requirements in a larger range.

[0066] The locking method between the third sleeve and the second sleeve 104 in this embodiment is similar to the locking method between the first sleeve 102 and the second sleeve 104 in the foregoing embodiment, and both are realized through the locking assembly. Specifically, the locking of the third sleeve is achieved by the second locking assembly, and the second locking assembly is provided at one end of the third sleeve extending into the second sleeve 104 and works in linkage with the first locking assembly 110. Such a design ensures the linkage between the sleeves when locking or unlocking, thus making the height adjustment operation more convenient and efficient.

[0067] By adding a third sleeve and its linkage locking structure, the advantage of this design is that it can provide a larger height adjustment range, and through the linkage between multiple locking components, the entire support system is more stable and reliable during the adjustment process, avoiding the loosening or incoordination problems that may occur when adjusting each sleeve separately, thereby enhancing the overall user experience and safety of the support assembly 100.

[0068] Through this linkage design, the first locking component 110 and the second locking component can work together, greatly simplifying the operation steps for the user to adjust and lock the support assembly 100. The user only needs to perform a single rotation action to simultaneously lock or unlock multiple sleeve parts. This linkage design not only improves the convenience of operation but also ensures the synchronization between the sleeves, thereby further enhancing the stability and safety of the overall support system.

[0069] Continue to refer to Figure 9 and Figure 10 , in this embodiment, the support foot assembly 10 further includes a connecting seat 300, and the connecting seat 300 is connected to one end of the first sleeve 102 away from the second sleeve 104; the support foot assembly 10 further includes a transmission assembly 400, and the transmission assembly 400 is arranged on the connecting seat 300 and is connected to the actuating rod 200, and the transmission assembly 400 is used to transmit the driving force for rotating it to the actuating rod 200.

[0070] In this embodiment, the support foot assembly 10 further includes a connecting seat 300, and the connecting seat 300 is arranged at one end of the first sleeve 102 away from the second sleeve 104. The connecting seat 300 not only plays a fixing role but also is provided with a transmission assembly 400 to achieve the driving function for the actuating rod 200. The transmission assembly 400 is installed on the connecting seat 300 and is connected to the actuating rod 200, and the transmission assembly 400 is used to transmit the driving force to the actuating rod 200 so that it can rotate.

[0071] Specifically, the design of the transmission assembly 400 can be diverse. For example, an oil cylinder, a motor, etc. can be used as the driving force source. These driving devices can provide sufficient power, and transmit the force to the actuating rod 200 through the transmission assembly 400, so that the actuating rod 200 rotates, and then the locking operation of the support foot assembly 10 is realized. The oil cylinder can provide hydraulic drive and drive with high stability, while the motor can precisely control the rotation speed and direction to adapt to different application requirements.

[0072] By arranging the transmission assembly 400 on the connecting seat 300, the adjustment process of the support foot assembly 10 in this embodiment becomes more efficient and convenient. The transmission assembly 400 can provide reliable power output, so that the user no longer needs to apply manual force when making height adjustments, greatly enhancing the convenience and accuracy of the operation.

[0073] Refer to Figure 9 , in this embodiment, the transmission assembly 400 includes a rack 401, and the actuating rod 200 is provided with a gear 201 adapted to the rack 401.

[0074] In this embodiment, the transmission assembly 400 includes a rack 401, and the actuating rod 200 is provided with a gear 201 that cooperates with the rack 401. The cooperation design of the rack 401 and the gear 201 is used to convert rotational motion into linear motion, so as to realize precise adjustment of the height of the support foot assembly 10.

[0075] During operation, the gear 201 on the actuating rod 200 meshes with the rack 401 in the transmission assembly 400. When the actuating rod 200 rotates, the gear 201 drives the rack 401 to move linearly, so as to realize the height adjustment of the second sleeve 104 relative to the first sleeve 102. This design provides a large transmission ratio, making the adjustment process more labor-saving. At the same time, through the close meshing of the gear 201 and the rack 401, the accuracy of the adjustment is ensured.

[0076] Through the cooperation of the rack 401 and the gear 201, the user can easily realize the height adjustment of the support foot assembly 10 while maintaining the stability and reliability of the system. In addition, the transmission efficiency of this structure is high, and it has good load capacity, which is suitable for various photography support requirements, whether it is an indoor or outdoor shooting environment.

[0077] The present utility model further provides a photography support frame 50, refer to Figure 10 , the photography support frame 50 includes a bearing seat 500, at least one driving assembly 600 and a plurality of support foot assemblies 10 as described in the foregoing embodiments. The specific structure of the support foot assembly 10 refers to the above embodiments. Since the photography support frame 50 adopts all the technical solutions of all the above embodiments, it at least has all the technical effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, the bearing seat 500 is connected to the connecting seat 300 of the plurality of support foot assemblies 10. The bearing seat 500 is used to mount photographic equipment. The driving assembly 600 is installed on the bearing seat 500 or the connecting seat 300 of the support foot assembly 10, and the driving assembly 600 is used to output power to the transmission assembly 400 of the support foot assembly 10;

[0078] Among them, the driving assembly 600 is a hydraulic pump or a motor.

[0079] In this embodiment, the carrier base 500 is connected to the connecting base 300 of the plurality of support leg assemblies 10, and the carrier base 500 is used for installing a photographic device. The driving assembly 600 is installed on the carrier base 500 or the connecting base 300 of the support leg assembly 10, and is mainly used to provide power to the transmission assembly 400 of the support leg assembly 10 to achieve the height adjustment and locking functions of the support leg assembly 10.

[0080] Among them, the driving assembly 600 can be a hydraulic pump or a motor. For example, when a scene with large thrust and high stability is required, a hydraulic pump can be selected as the driving assembly 600, and the transmission assembly 400 is driven hydraulically to achieve precise adjustment and stable locking of the support leg assembly 10. In the case where precise control is required, a motor can be used as the driving assembly 600, and precise control of the transmission assembly 400 is achieved through electric drive.

[0081] By using the driving assembly 600, the photographic support frame 50 in this embodiment can be more conveniently and efficiently adjusted in height.
