Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to a tripod that is easy to deploy quickly. Background Technology

[0002] A tripod is a piece of equipment used for mounting photographic equipment for fixed-point shooting. Existing tripods include a center column, a sliding sleeve, several legs, and several support rods. The sliding sleeve passes through the center column and can slide up and down along it. The legs are spaced apart around the sliding sleeve and rotatably connected to it. The support rods are also spaced apart around the center column and rotatably connected to both the center column and the legs. When the sliding sleeve moves down, it causes the legs to fold outward and the support rods to fold down, thus unfolding the tripod. When the sliding sleeve moves up, it causes the legs to fold inward and the support rods to fold up, thus folding the tripod. Because existing tripods unfold by pushing the sliding sleeve to rotate the legs and support rods, the tripod cannot open quickly and automatically, resulting in poor ease of operation. Utility Model Content

[0003] The purpose of this invention is to provide a tripod that can be easily and quickly unfolded, in order to solve the problem that existing tripods unfold by pushing a sliding sleeve to rotate the legs and support rods, and the tripod cannot be opened quickly on its own, resulting in poor ease of operation.

[0004] This utility model is achieved through the following technical solution:

[0005] A tripod for easy and quick deployment includes a central column, a sliding sleeve, and several legs. The sliding sleeve passes through the central column and can slide along the central column. The several legs are spaced apart in the circumferential direction of the sliding sleeve and are rotatably connected to the sliding sleeve. The legs can rotate around their connection point with the sliding sleeve to switch between an deployed state and a retracted state. The central column and the legs are provided with a drive assembly and a locking structure. The drive assembly is used to deploy the legs outward to switch to the deployed state, and the locking structure is used to lock the legs in the retracted state.

[0006] Furthermore, the drive assembly includes a support rod, an inner torsion spring, and an outer torsion spring. The support rod is rotatably connected to the central column and the support leg, respectively. The inner torsion spring is located at the end of the support rod connected to the central column and has two free ends that abut against the central column and the support rod, respectively. The outer torsion spring is located at the end of the support rod connected to the support leg and has two free ends that abut against the support leg and the support rod, respectively. The support rod is driven by the inner and outer torsion springs to rotate outward, thereby switching the support leg to the unfolded state.

[0007] Furthermore, the support rod has an inner shaft portion and an outer shaft portion, the central column is rotatably connected to the support rod at the inner shaft portion, the support leg is rotatably connected to the support rod at the outer shaft portion, the inner torsion spring is rotatably connected to the support rod at the inner shaft portion, and the outer torsion spring is rotatably connected to the support rod at the outer shaft portion.

[0008] Furthermore, the support rod has an outer fixed groove into which the free end of the outer torsion spring is inserted; and / or the support rod has an inner fixed groove into which the free end of the inner torsion spring is inserted.

[0009] Furthermore, the central column has a limiting hole for the free end of the inner torsion spring to be inserted.

[0010] Furthermore, the drive assembly includes a double torsion spring, which has an inner torsion part, an outer torsion part, and a connecting spring part. The inner torsion part is rotatably connected to the central column and has a free end that abuts against the central column. The outer torsion part is rotatably connected to the support leg and has a free end that abuts against the support leg. The connecting spring part connects the inner torsion part and the outer torsion part. The support leg is driven by the double torsion spring to flip outward and switch to the unfolded state.

[0011] Furthermore, the central column is provided with an inner limiting hole for the free end of the inner torsion part to be inserted, and the support leg is provided with an outer limiting groove for the free end of the outer torsion part to be placed.

[0012] Furthermore, the locking structure includes a locking seat on the central column and a locking hole on the leg. The locking seat can move up and down relative to the central column and has a latch. When the leg is retracted and close to the central column, the latch engages with the locking hole to lock the leg in the retracted state. When the locking seat moves upward, the latch moves away from the locking hole to release the leg.

[0013] Furthermore, the central column is provided with an elastic element that drives the locking seat to move downward so that the buckle locks the buckle hole.

[0014] Furthermore, a connecting rod is provided on the central column, the locking seat is slidably connected to the central column via the connecting rod, and the elastic element passes through the connecting rod and elastically abuts against the central column and the locking seat respectively.

[0015] The advantage of this technical solution is that by configuring a drive component between the central column and the legs to switch the legs to the extended state and a locking structure to lock the legs in the retracted state, the legs can quickly extend outward when the locking structure is unlocked, without having to push the sliding sleeve to extend them. This makes the operation simple and quick. At the same time, the locking structure can lock the legs when they are retracted, making them easy to store. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1: As Figure 1-10 As shown, the tripod that is easy to deploy quickly includes a central column 1, a sliding sleeve 2, and several legs 3. The sliding sleeve 2 passes through the central column 1 and can slide along the central column 1. Several legs 3 are distributed at intervals in the circumference of the sliding sleeve 2 and are rotatably connected to the sliding sleeve 2. The legs 3 can rotate around their connection with the sliding sleeve 2 as an axis to switch between the deployed state and the retracted state. The central column 1 and the legs 3 are provided with a drive assembly 4 and a locking structure 5. The drive assembly 4 is used to make the legs 3 extend outward to switch to the deployed state, and the locking structure 5 is used to lock the legs 3 in the retracted state. This embodiment provides a tripod that is easy to unfold quickly, solving the problem that existing tripods unfold by pushing a sliding sleeve to rotate the legs and support rods, and the tripod cannot be opened quickly on its own, resulting in poor ease of operation. The main solution is to configure a drive component 4 between the central column 1 and the legs 3 to switch the legs 3 to the unfolded state and a locking structure 5 to lock the legs 3 in the retracted state. When the locking structure 5 is unlocked, the legs 3 can quickly unfold outward without having to push the sliding sleeve 2 to unfold, making the operation simple and quick. At the same time, the locking structure 5 can lock the legs 3 when they are retracted, making them easy to store.

[0033] In Embodiment 1 of this utility model, the driving assembly 4 includes a support rod 401, an inner torsion spring 402, and an outer torsion spring 403. The support rod 401 is rotatably connected to the central column 1 and the support leg 3, respectively. The inner torsion spring 402 is located at the end of the support rod 401 connected to the central column 1 and has two free ends that abut against the central column 1 and the support rod 401, respectively. The outer torsion spring 403 is located at the end of the support rod 401 connected to the support leg 3 and has two free ends that abut against the support leg 3 and the support rod 401, respectively. When the support rod 401 is driven to rotate outward by the inner torsion spring 402 and the outer torsion spring 403, it causes the support leg 3 to unfold outward and switch to the unfolded state. The above configuration involves configuring the drive assembly 4 as a support rod 401 rotatably connected to the central column 1 and the support leg 3, an inner torsion spring 402 located at the end of the support rod 401 connected to the central column 1 and abutting against the central column 1 and the support rod 401, and an outer torsion spring 403 located at the end of the support rod 401 connected to the support leg 3 and abutting against the support leg 3 and the support rod 401. This configuration allows the support rod 401 to rotate outwards driven by the inner torsion spring 402 and the outer torsion spring 403, thereby enabling the support leg 3 to unfold outwards and switch to the unfolded state. This achieves rapid unfolding of the support leg 3 and provides good support when the support leg 3 is in the unfolded state.

[0034] In Embodiment 1 of this utility model, the support rod 401 has an inner shaft portion 404 and an outer shaft portion 405. The central column 1 is rotatably connected to the support rod 401 via the inner shaft portion 404, the support leg 3 is rotatably connected to the support rod 401 via the outer shaft portion 405, the inner torsion spring 402 is rotatably connected to the support rod 401 via the inner shaft portion 404, and the outer torsion spring 403 is rotatably connected to the support rod 401 via the outer shaft portion 405. This arrangement, by configuring the inner shaft portion 404 rotatably connected to the central column 1 and the outer shaft portion 405 rotatably connected to the support leg 3 on the support rod 401, with the inner torsion spring 402 disposed on the inner shaft portion 404 and the outer torsion spring 403 disposed on the outer shaft portion 405, ensures a reasonable, compact, stable, and effective assembly of the support rod 401, central column 1, support leg 3, inner torsion spring 402, and outer torsion spring 403, resulting in excellent driving performance.

[0035] In Embodiment 1 of this utility model, the support rod 401 has an outer fixed groove 406 for inserting the free end of the outer torsion spring 403 and an inner fixed groove 407 for inserting the free end of the inner torsion spring 402. This arrangement, by configuring the outer fixed groove 406 for inserting the free end of the outer torsion spring 403 and the inner fixed groove 407 for inserting the free end of the inner torsion spring 402 on the support rod 401, ensures stable assembly of the outer torsion spring 403 and the inner torsion spring 402 with the support rod 401 and provides excellent driving performance.

[0036] In Embodiment 1 of this utility model, the central column 1 has a limiting hole 101 for inserting the free end of the inner torsion spring 402. The above-mentioned arrangement, by configuring the limiting hole 101 on the central column 1 for inserting the free end of the inner torsion spring 402, makes the assembly of the inner torsion spring 402 and the central column 1 stable and the driving effect good.

[0037] In Embodiment 1 of this utility model, when the plurality of legs 3 are switched to the folded state, they enclose to form a cavity (not shown in the figure) for accommodating the central column 1 and the drive assembly 4. By configuring the plurality of legs 3 to enclose to form a cavity for accommodating the central column 1 and the drive assembly 4 when switched to the folded state, the storage size of the leg frame, which is easy to unfold, is small when the plurality of legs 3 are switched to the folded state.

[0038] In embodiment 1 of this utility model, the locking structure 5 includes a locking seat 6 on the central column 1 and a locking hole 301 on the support leg 3. The locking seat 6 can move up and down relative to the central column 1 and has a latch 601. When the support leg 3 is folded up and close to the central column 1, the latch 601 engages with the locking hole 301 to lock the support leg 3 in the folded state. When the locking seat 6 moves upward, the latch 601 moves away from the locking hole 301 to release the support leg 3. The above arrangement, by configuring the locking seat 6 on the central column 1, configuring the latch 601 on the locking seat 6, and configuring the locking hole 301 on the support leg 3, allows the support leg 3 to be locked in the folded state when it is folded up and close to the central column 1 through the engagement of the locking hole 301 and the latch 601. At the same time, the locking seat 6 can be pressed to move upward and release the support leg 3, making the operation quick and simple.

[0039] In Embodiment 1 of this utility model, the central column 1 is provided with an elastic element 7 that drives the locking seat 6 to move downward, causing the buckle 601 to engage with the locking hole 301. Specifically, the elastic element 7 is a spring. The above arrangement, by configuring the elastic element 7 on the central column 1 to drive the locking seat 6 to move downward, causing the buckle 601 to engage with the locking hole 301, ensures a stable engagement between the buckle 601 and the locking hole 301, resulting in a good locking effect.

[0040] In Embodiment 1 of this utility model, a connecting rod 8 is provided on the central column 1, and a locking seat 6 is slidably connected to the central column 1 via the connecting rod 8. An elastic element 7 is passed through the connecting rod 8 and elastically abuts against the central column 1 and the locking seat 6 respectively. The above arrangement, by configuring the connecting rod 8 on the central column 1 to slide with the locking seat 6 and configuring the elastic element 7 on the connecting rod 8, makes the assembly of the elastic element 7 stable.

[0041] Example 2: Figure 11-13 As shown, the difference between this embodiment and Embodiment 1 is that the driving assembly 4 includes a double torsion spring 408. The double torsion spring 408 has an inner torsion part 409, an outer torsion part 410, and a connecting spring part 411. The inner torsion part 409 is rotatably connected to the central column 1 and has a free end that abuts against the central column 1. The outer torsion part 410 is rotatably connected to the support leg 3 and has a free end that abuts against the support leg 3. The connecting spring part 411 connects the inner torsion part 409 and the outer torsion part 410. The support leg 3 is driven by the double torsion spring 408 to flip outwards and switch to the unfolded state. The above configuration, by configuring the driving assembly 4 as a double torsion spring 408, allows the support leg 3 to be driven by the double torsion spring 408 to flip outwards and switch to the unfolded state, resulting in a simple structure and convenient implementation.

[0042] In embodiment 2 of this utility model, the central column 1 is provided with an inner limiting hole (not shown in the figure) for the free end of the inner torsion part 409 to be inserted, and the support leg 3 is provided with an outer limiting groove (not shown in the figure) for the free end of the outer torsion part 410 to be inserted. The above arrangement, by configuring the inner limiting hole on the central column 1 for the free end of the inner torsion part 409 to be inserted, and configuring the outer limiting groove on the support leg 3 for the free end of the outer torsion part 410 to be inserted, makes the double torsion spring 408 stably assembled and provides good driving force.
