Description

Technical Field

[0001] This utility model relates to the field of tripod technology, and more specifically, to a tripod that can be opened and closed quickly. Background Technology

[0002] In many fields such as photography, observation, and surveying, tripods are crucial tools for stabilizing various equipment, and their performance directly affects the final work results. Traditional tripod designs often have many limitations, making it difficult to meet the diverse needs of modern users for efficiency, ease of operation, and stability.

[0003] However, existing tripods have the following problems when in use:

[0004] Tripods typically employ complex mechanical connection methods, such as direct fastening of multiple sets of nuts and bolts. The lack of flexible and reliable linkage design between the legs and connecting components results in users having to spend a lot of time loosening and tightening multiple bolts one by one during the tripod deployment process. This operation is cumbersome and inefficient, especially in outdoor shooting or emergency work scenarios, where this inefficient deployment and folding method seriously affects the work progress.

[0005] This utility model features a combination of rotating holes and grooves, connecting arms and rods, sliding grooves and sliding columns to ensure smooth deployment and retraction of the tripod, precise trajectory, and uniform force distribution on each component. This provides reliable support for the equipment being carried, effectively reducing the risk of swaying and displacement, and ensuring stability even in complex environments. Users can quickly deploy or retract the tripod by operating a single leg, making operation simple and saving time on equipment installation and storage. It can efficiently meet the usage needs of different scenarios. Utility Model Content

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a tripod that can be opened and closed quickly.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-opening and closing tripod, comprising: a base, a connecting piece movably connected to the upper end of the base, legs surrounding the outer side of the connecting piece, a fixing piece at the upper end of the connecting piece, a connecting rod fixedly installed at the bottom of the connecting piece, a connecting arm nested and fixedly installed on the outer surface of the connecting rod, the connecting arm being fixedly connected to the bottom of the legs, three legs, each leg having a sliding groove at its upper end, and the connecting piece being rotatably installed below the fixing piece via a connecting column.

[0008] A further preferred embodiment: each of the triangular portions at the upper end of the base is provided with a rotating hole, which is rotatably connected to a fixing bolt.

[0009] A further preferred embodiment: a through hole is provided in the middle of the upper end of the connecting piece, the through hole is rotatably connected to the connecting post, a first connecting hole is provided on the inner side of the upper end of the connecting arm, and a second connecting hole is provided on the outer side of the upper end of the connecting arm.

[0010] A further preferred embodiment: the first connecting hole is fixedly connected to the connecting rod, and the second connecting hole is fixedly connected to the leg piece.

[0011] A further preferred embodiment: the upper end of the leg piece is threaded with a fixing bolt, the fixing bolt is threadedly connected to the fixing piece, the bottom of the fixing bolt is provided with a rotating groove, the bottom of the fixing bolt is embedded in the rotating hole, and the rotating groove is rotatably connected to the base.

[0012] A further preferred embodiment: a limiting groove is formed at the bottom of the leg piece, and a limiting post is fixedly installed on the outer side of the limiting groove, and the limiting post is rotatably connected to the second connecting hole.

[0013] A further preferred embodiment: each of the upper triangular portions of the fixing plate is provided with a connecting hole three, which is threadedly connected to the fixing bolt. A sliding column is fixedly installed on one side of the bottom of each connecting hole three, and the sliding column is slidably connected to the sliding groove.

[0014] A further preferred embodiment: a stabilizing bolt is threaded to the middle of the upper end of the fixing plate, and a connecting post is nested at the bottom of the stabilizing bolt.

[0015] Beneficial effects:

[0016] 1. With connecting rods and connecting arms, when the user pulls any leg outward, the upper outer side of the connecting arm is rigidly connected to the leg through connecting hole two, allowing the movement of the leg to be directly transmitted to the connecting arm. The connecting arm is nested on the connecting rod, and its upper inner connecting hole one is fixed to the connecting rod. In this way, the connecting arm starts to rotate around the connecting rod as the axis. Since the connecting rod is fixed to the bottom of the connecting piece, the rotation of the connecting arm will cause the connecting piece to rotate as well, which in turn causes the other two legs to unfold outward in sync, ultimately forming a stable triangular support structure quickly and smoothly. The whole process is seamless, efficient and convenient. In the folding process, pushing a leg inward also uses the tight connection between the connecting arm, the leg, and the connecting rod. The inward displacement of the leg drives the connecting arm to rotate in the opposite direction around the connecting rod. This rotational force is transmitted to the connecting piece, causing the other legs to fold inward in coordination, allowing the tripod to quickly return to its initial compact state, making it easy to carry and store.

[0017] 2. By incorporating sliding grooves and sliding columns, during tripod deployment, the sliding columns on the fixed plate and the sliding grooves on the upper ends of the legs act as guides. The sliding columns slide stably along the sliding grooves, defining a precise trajectory for the outward movement of the legs. This effectively prevents problems such as swaying or misalignment of the legs due to uneven force or external interference during deployment, ensuring that each leg moves smoothly and accurately to the appropriate position according to design requirements. This quickly and reliably forms a stable triangular support structure, greatly improving the success rate and efficiency of deployment operations. During retraction... In this stage, when pushing inward from any leg piece, the cooperation between the sliding column and the sliding groove is equally crucial. The sliding column slides in the opposite direction along the sliding groove, guiding the leg pieces to retract inward in an orderly manner, so that the three leg pieces 3 can neatly and uniformly return to the initial state of tightly surrounding the connecting piece. Moreover, this design of the sliding groove and the sliding column also enhances the stability of the overall tripod structure. During the use of the tripod, whether bearing the weight of the equipment or encountering slight shaking or vibration from the outside, the sliding column always fits in the sliding groove, restraining the slight displacement of the leg pieces, making the tripod's support structure more stable.

[0018] 3. By incorporating a rotating groove and a rotating hole, when the user pulls the legs outward to initiate the tripod's unfolding process, the bottom of the fixing bolt engages with the rotating hole at the upper triangular section of the base. Furthermore, the rotating groove at its bottom fits tightly with the base, providing a stable and flexible pivot point for the leg movement. This ensures that the legs can smoothly rotate around the rotating hole with the fixing bolt as the axis when expanding outward, preventing jamming due to rotational obstruction and making the unfolding action seamless. On the other hand, precise rotational constraints ensure that the leg movement trajectory is strictly controllable and will not deviate from the intended path. The predetermined path ensures that the three legs can extend outwards precisely and synchronously, quickly establishing a stable triangular support structure, greatly improving the ease of operation and deployment efficiency. During the retraction phase, when the legs are pushed inwards, the rotating groove and rotating hole continue to work together. The rotating hole serves as a fixed reference point, and the rotating groove, in conjunction with the base, guides the fixing bolts to rotate smoothly in reverse, allowing the legs to retract smoothly inwards along the predetermined reverse trajectory. Just like the deployment process, this ensures the smoothness and accuracy of the retraction action, allowing the tripod to quickly return to its initial compact state, making it convenient to carry and store.

[0019] 4. In summary, this type of quick-opening tripod, through the design of rotating holes, connecting rods, connecting arms, legs, sliding grooves, and sliding columns, provides a key fulcrum for the rotation of the legs by the rotating hole at the upper triangular part of the base. This hole, in conjunction with the rotating groove at the bottom of the fixing bolt, ensures smooth and precise extension and retraction of the legs. The connecting rod at the bottom of the connecting piece connects to the connecting arm nested within it. The inner side of the connecting arm is fixed to the connecting rod via connecting hole one, while the outer side connects to the legs via connecting hole two. This allows the movement of the legs to drive the connecting piece to rotate synchronously, achieving rapid opening and closing. The sliding groove at the upper end of the legs slides in conjunction with the sliding column on one side of connecting hole three on the fixing piece, precisely guiding and limiting the legs when they are extended or retracted, preventing displacement deviations and ensuring that the tripod can quickly and stably switch between a retracted portable state and an extended support state to meet different usage needs.

[0027] The following will refer to the appendix in the embodiments of this utility model. Figures 1-6 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0028] Please see Figure 1-6In this embodiment of the invention, a quick-opening and closing tripod includes: a base 1, a connecting piece 2 movably connected to the upper end of the base 1, legs 3 arranged around the outer side of the connecting piece 2, a fixing piece 4 at the upper end of the connecting piece 2, a connecting rod 202 fixedly installed at the bottom of the connecting piece 2, a connecting arm 203 nested and fixedly installed on the outer surface of the connecting rod 202, the connecting arm 203 being fixedly connected to the bottom of the legs 3, three legs 3, each leg 3 having a sliding groove 301 at its upper end, and a fixing bolt 302 threadedly connected to the upper end of each leg 3, the fixing bolt 302 being threadedly connected to the fixing piece 4. A stabilizing bolt 403 is threadedly connected to the upper center of the fixing plate 4. A connecting post 404 is nested at the bottom of the stabilizing bolt 403. The connecting plate 2 is rotatably mounted below the fixing plate 4 via the connecting post 404. Rotating holes 101 are provided at the triangular portion of the upper end of the base 1. The rotating holes 101 are rotatably connected to the fixing bolts 302. A rotating groove 303 is provided at the bottom of the fixing bolts 302, and the bottom of the fixing bolts 302 is embedded inside the rotating holes 101. The rotating groove 303 is rotatably connected to the base 1. When the tripod is in its unused, folded state, the three legs 3 tightly surround the outside of the connecting plate 2. When the tripod needs to be unfolded, grasp the upper part of any one of the legs 3 and apply force outward. The leg 3 will rotate around the connection point between the connecting arm 203 and the connecting rod 202. Since the connecting arm 203 is fixed to the bottom of the leg 3 and nested on the connecting rod 202, as the leg 3 unfolds outward, it causes the connecting arm 203 to rotate around the connecting rod 202. Because the connecting arm 203 is fixedly connected to the connecting rod 202, it will cause the entire connecting piece 2 to rotate, and the other two legs 3 will also unfold synchronously, gradually forming a stable supporting triangular structure. During this process... The bottom of the fixing bolt 302 is embedded in the rotating hole 101 and the rotating groove 303 is rotatably connected to the base 1, providing a flexible and stable rotation fulcrum for the unfolding action of the leg piece 3, ensuring that the unfolding process of the leg piece 3 is smooth and there will be no jamming or deviation from the predetermined trajectory. When the tripod needs to be folded up after use, start from any one of the leg pieces 3 and push inward to make the leg piece 3 fold around the connection part of the connecting arm 203 and the connecting rod 202 and fold towards the connecting piece 2. The other two leg pieces 3 will also fold inward in the same way during this process, and finally return to the initial state of tightly surrounding the connecting piece 2.

[0029] In this embodiment of the invention, a through hole 201 is provided in the middle of the upper end of the connecting piece 2, and the through hole 201 is rotatably connected to the connecting post 404. A first connecting hole 204 is provided on the inner side of the upper end of the connecting arm 203, and a second connecting hole 205 is provided on the outer side of the upper end of the connecting arm 203. The first connecting hole 204 is fixedly connected to the connecting rod 202, and the second connecting hole 205 is fixedly connected to the leg piece 3. A limit groove 304 is provided at the bottom of the leg piece 3, and a limit post 305 is fixedly installed inside and outside the limit groove 304. The limit post 305 is rotatably connected to the second connecting hole 205. The through hole 201 in the middle of the upper end of the connecting piece 2 is rotatably connected to the connecting post 404. This design plays a key pivotal role in the overall operation of the tripod, enabling operations such as unfolding, retracting, and stabilizing the tripod. When the connecting piece 2 rotates flexibly around the connecting post 404 through the through hole 201, the fixed piece 4 and the connecting piece 2 maintain a relatively fixed positional relationship while also being able to rotate relative to each other to a certain extent. This coordinates with the movement of the leg piece 3, ensuring the continuity and adjustability of the entire tripod structure. When the leg piece 3 rotates through the connecting arm 203, the limiting groove 304 can limit the displacement distance of the connecting arm 203 to prevent it from rotating excessively. The limiting post 305 is connected to the connecting arm 203, so that when the connecting arm 203 rotates, it can drive the leg piece 3 to rotate. The limiting post 305 is rotatably connected to the second connecting hole 205, so that when the leg piece 3 reaches the retracted position, it can rotate further through the second connecting hole 205, allowing the leg piece 3 to be better retracted to the inner side near the tripod.

[0030] In this embodiment of the invention, each of the upper triangular portions of the fixed plate 4 is provided with a connecting hole 401, which is threadedly connected to a fixing bolt 302. A sliding post 402 is fixedly installed on one side of the bottom of each connecting hole 401, and the sliding post 402 is slidably connected to a sliding groove 301. The fixed plate 4 is fixed above the connecting plate 2 through the threaded connection between the connecting hole 401 and the fixing bolt 302, so that the leg plate 3 can maintain a relatively stable connection with the fixed plate 4 after being unfolded or retracted and fixed in position, thereby ensuring the stability of the overall tripod structure. The sliding post 402 is fixedly installed on one side of the bottom of the connecting hole 401 and slidably connected to the sliding groove 301 at the upper end of the leg plate 3. This design... The sliding column 402 provides effective guidance and limiting functions for the movement of the leg piece 3. During the tripod unfolding process, when the leg piece 3 moves outward, the sliding column 402 slides along the sliding groove 301, so that the movement trajectory of the leg piece 3 is limited to a reasonable range, avoiding the leg piece 3 from swinging or misaligning off the predetermined direction. This ensures that the leg piece 3 can be accurately and smoothly unfolded to the appropriate position according to the design requirements, thereby forming a stable triangular support structure. Similarly, when the leg piece 3 is retracted, the sliding cooperation between the sliding column 402 and the sliding groove 301 can also guide the leg piece 3 to retract smoothly inward, so that it can orderly return to the initial compact state, improving the convenience and accuracy of the tripod opening and closing operation.

[0031] Working principle: When the tripod is in its unused, folded state, the three legs 3 are tightly wrapped around the outside of the connecting piece 2. All components are in a relatively static and compact initial position. The user grasps the upper part of any one leg 3 and applies force outward. Because the leg 3 can rotate around the connection point between the connecting arm 203 and the connecting rod 202, and because the connecting arm 203 is fixed to the bottom of the leg 3 and nested on the connecting rod 202, the outward unfolding of the leg 3 simultaneously causes the connecting arm 203 to rotate around the connecting rod 202. Since the connecting arm 203 is fixedly connected to the connecting rod 202, when the connecting arm 203 rotates... When in motion, the entire connecting piece 2 rotates, causing the other two leg pieces 3 to unfold synchronously. During the unfolding of the leg pieces 3, the bottom of the fixing bolt 302 is embedded in the rotating hole 101 at the upper triangular part of the base 1, and the rotating groove 303 is rotatably connected to the base 1, providing a flexible and stable rotation fulcrum for the unfolding action of the leg pieces 3, ensuring that the unfolding process of the leg pieces 3 is smooth and there will be no jamming or deviation from the predetermined trajectory. The connecting hole 401 at the upper triangular part of the fixing piece 4 is threadedly connected to the fixing bolt 302, fixing the fixing piece 4 above the connecting piece 2. At the same time, the bottom of the connecting hole 401... The sliding column 402 on the side is slidably connected to the sliding groove 301 at the upper end of the leg piece 3, providing guidance and limiting functions for the movement of the leg piece 3. When the leg piece 3 moves outward, the sliding column 402 slides along the sliding groove 301, limiting the movement trajectory of the leg piece 3, so that it unfolds accurately and smoothly to the appropriate position, and finally gradually forms a stable supporting triangular structure. When the tripod needs to be folded up after use, start from any leg piece 3 and push the selected leg piece 3 inward, causing the leg piece 3 to retract around the connection part of the connecting arm 203 and the connecting rod 202 towards the connecting piece 2. The other two leg pieces 3 will also retract around this connection. During the process, the legs fold inwards simultaneously. When the connecting arm 203 rotates, the limiting groove 304 can limit the displacement distance of the connecting arm 203 to prevent it from rotating excessively. The limiting post 305 is connected to the connecting arm 203, so that when the connecting arm 203 rotates, it can drive the legs 3 to rotate. The limiting post 305 is rotatably connected to the second connecting hole 205, so that when the legs 3 reach the folded position, they can rotate further through the second connecting hole 205, so that the legs 3 can be better folded up close to the inside of the tripod. Finally, the three legs 3 return to the initial state of tightly surrounding the connecting piece 2, completing the folding of the tripod.
