Description

Technical Field

[0001] The utility model relates to the technical field of photographic accessories, in particular to a tripod leg tube structure. Background Art

[0002] A tripod generally consists of a leg (the main body), a pan head, a quick-release plate, and various accessories (such as a center column, spikes, and a tripod bag). The leg is the base of the tripod, providing support and stability. Currently, tripod legs often feature a multi-stage telescopic design, allowing the tripod to adjust its height to suit different shooting needs.

[0003] In the prior art, legs with a multi-stage telescopic design typically have support plates installed on the inner top of each level of the telescopic sleeve. The elasticity of the support plates significantly enhances the leg's support force, enabling it to better support products or displayed items. This enhanced support helps ensure that the leg remains stable when carrying heavy objects and is less likely to bend or break. Furthermore, the elasticity of the support plates allows the user to adjust the leg's height as needed. By adjusting the degree of compression of the support plates, the overall length of the leg can be easily changed to accommodate usage scenarios at different heights.

[0004] Traditional tripods require two internal support plates, making them prone to falling during maintenance. Consequently, currently available support plates are typically integrated. However, these integrated plates are connected at the top, forming a single piece, while the individual support plates are stacked axially. This occupies a considerable amount of space when stored, making it difficult to use. To address this issue, we have proposed a tripod leg tube structure that effectively addresses these drawbacks. Utility Model Content

[0006] The utility model is realized by the following technical solutions: a tripod leg structure, including a leg body, a plurality of stages of telescopic sleeves are sequentially arranged from the outside to the inside of the leg body, and a sheet body is provided on both sides of the upper end of each stage of the telescopic sleeve, and further comprising:

[0007] Connecting ribs, which are integrally formed between two sheets at the same level and are provided with at least one connecting rib. The two sheets at the same level and the connecting ribs cooperate to form a supporting sheet body that is movably sleeved on the upper end of the telescopic sleeve. The positions of the connecting ribs at different levels are staggered.

[0008] The positioning component is arranged between the supporting piece body and the telescopic sleeve at the same level, and is used to prevent the supporting piece body from separating from the telescopic sleeve at the same level.

[0011] Optionally, a receiving groove is provided on the top of the sheet body, and the end of the connecting rib is integrally formed in the receiving groove.

[0012] Optionally, the gap between the two sheets at the same level forms two telescopic guide grooves, and a guide rail that matches each telescopic guide groove is fixedly connected axially to the inner side of the telescopic sleeve of the outer level.

[0013] Optionally, the positioning assembly includes positioning holes provided on both sides of the telescopic sleeve, and positioning posts corresponding to the positioning holes are fixedly connected to the support plate body at the same level.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example: See Figures 1 to 5 A tripod leg structure includes a leg body 1 connected to the tripod frame for supporting the tripod. Several stages of telescopic sleeves 2 are sequentially arranged within the leg body 1 from the outside to the inside. Each stage of telescopic sleeve 2 has a plate 3 on both sides of its upper end. It should be noted that in this embodiment, there are three stages of telescopic sleeves 2, with a plate 3 located between adjacent stages.

[0026] Furthermore, the leg body 1 is a profiled tube, and the outermost telescopic sleeve 2 needs to move relative to the profiled tube. Therefore, the outermost telescopic sleeve 2 does not use the plate 3 proposed in this embodiment. Instead, a profiled support plate adapted to the profiled tube is provided at the top. This profiled structure allows the outermost telescopic sleeve 2 and the leg body 1 to move axially relative to each other, but not to rotate relative to each other, eliminating the need for an additional guide structure.

[0027] The specific structure of the special-shaped support sheet, such as Figure 6 As shown, a non-enclosed annular piece 9 is movably sleeved on the upper end of the outermost telescopic sleeve 2. The non-enclosed design can reserve a certain amount of deformation space, which is convenient for assembly on the outermost telescopic sleeve 2. A special-shaped support body 10 that slides with the inner surface of the special-shaped tube is fixed on the outer surface of the non-enclosed annular piece 9. The design of the special-shaped structure allows the outermost telescopic sleeve 2 and the leg tube body 1 to move relative to each other in the axial direction. Positioning grooves are provided on both sides of the outermost telescopic sleeve 2, and positioning rods 11 corresponding to each positioning groove are fixedly connected to the inner surface of the non-enclosed annular piece 9. When the non-enclosed annular piece 9 is assembled on the outermost telescopic sleeve 2, the positioning rods 11 need to be inserted into the positioning grooves to prevent the special-shaped support piece from falling off the outermost telescopic sleeve 2.

[0028] Further, such as Figure 4 and Figure 5 As shown, the gap between the two sheets 3 of the same level forms two telescopic guide grooves 7; the inner sides of the two telescopic sleeves 2 located at the outer level are fixedly connected axially with guide rails 8 that match each telescopic guide groove 7 one by one. Through the mutual cooperation between the telescopic guide grooves 7 and the guide rails 8, the inner and outer telescopic sleeves 2 can move relative to each other along the axial direction.

[0029] This embodiment also includes connecting ribs 4 and positioning components 5. The connecting ribs 4 are integrally formed between two plates 3 at the same level, with at least one being provided. This integrated design prevents them from falling off, improving stability during use. The two plates 3 at the same level and the connecting ribs 4 cooperate to form a support plate body that is flexibly sleeved onto the upper end of the telescopic sleeve 2. The connecting ribs 4 at different levels are staggered to reduce the storage volume of the support plates when stacked axially. This results in a simple, compact structure that facilitates use.

[0030] In this embodiment, if Figure 3 As shown, in the non-assembled state, the support sheet body is in a naturally expanded state, and the connecting rib 4 is a V-shaped structure; Figure 4 As shown, in the assembled state, the support piece body is sleeved on the upper end of the telescopic sleeve 2, and under the obstruction of the outer telescopic sleeve 2, the support piece body is in a stressed bending state, and the V-shaped structure provides deformation recovery force for the support piece body to make the support piece body in close contact with the outer telescopic sleeve 2.

[0031] like Figure 2 and Figure 4 As shown, a receiving groove 6 is provided on the top of the sheet body 3, and the end of the connecting rib 4 is integrally formed in the receiving groove 6. When the supporting sheet bodies of different levels are axially stacked, the connecting ribs 4 are staggered in the receiving groove 6, thereby further reducing the storage volume.

[0032] The positioning assembly 5 is provided between the supporting piece body and the telescopic sleeve 2 at the same level, and is used to prevent the supporting piece body from being separated from the telescopic sleeve 2 at the same level. Figure 3 and Figure 5 As shown, the positioning assembly 5 includes positioning holes 501 opened on both sides of the telescopic sleeve 2, and positioning posts 502 corresponding to the positioning holes 501 are fixedly connected to the support plate body at the same level.

[0033] In this embodiment, the positioning column 502 is directly fixed to the side of the sheet body 3. When the support sheet body is installed to the top of the telescopic sleeve 2 of the same level, the support sheet body is in a stressed and bent state, so that the positioning column 502 can be inserted into the corresponding positioning hole 501; when the telescopic sleeve 2 of this level is inserted into the telescopic sleeve 2 of the outer level, due to the obstruction of the outer level telescopic sleeve 2, the support sheet body is always in a stressed and bent state, so that under the action of the positioning column 502 and the positioning hole 501, the support sheet body will not fall off from the top of the telescopic sleeve 2 of the same level.

[0034] During use, the support piece body is bent, and the bent support piece body is positioned and installed on the top of the corresponding telescopic sleeve 2 through the cooperation of the positioning column 502 and the positioning hole 501. Then, through the internal cooperation of the telescopic guide groove 7 and the guide rail 8, the telescopic sleeve 2 is axially inserted into the telescopic sleeve 2 of the outer stage. Repeating this process can successfully assemble the leg tube with a multi-stage telescopic design. During use, the support piece body of each stage is always in a stressed and bent state. The V-shaped structure provides the support piece body with a force to recover its deformation, so that the support piece body is in close contact with the telescopic sleeve 2 of the outer stage, thereby utilizing friction to enhance the supporting force of the leg tube. When the leg tube with a multi-stage telescopic design is retracted, the connecting ribs 4 on the support piece bodies of different stages are staggered. Therefore, when the support piece bodies of each stage are axially stacked, the storage volume can be reduced.

[0035] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.
