Description

Technical Field

[0001] This utility model relates to the technical field of support equipment, and in particular to a stable support frame. Background Technology

[0002] Support tripods are common accessories used to stably support various electronic devices such as projectors, smartphones, and cameras. Their core function is to provide a stable support platform to ensure that the equipment remains stable in various usage scenarios and to prevent it from tipping over or shaking.

[0003] For ease of carrying and storage, modern support legs are generally designed with a collapsible structure. They typically include a main pole and a connecting seat fitted onto the main pole. Several support legs are hinged to the connecting seat. When not in use, the support legs are folded up close to the main pole, significantly reducing the overall volume. When in use, the connecting seat is slid on the main pole to unfold the support legs, which then form a support structure that, together with the main pole, supports the equipment placed on it.

[0004] In existing support tripods, when the support legs are unfolded to form a support structure, the main rod only contacts the inner wall of the connecting seat. The connecting seat has a relatively short length along the axial direction of the main rod, and when the main rod is fully extended, the connecting seat is close to the bottom of the main rod. At this time, the top of the main rod (which has a clamp for connecting and holding external shooting equipment) is prone to shaking, especially when the top of the main rod is set to multiple sections. When the main rod is fully opened and the length is long, the top of the main rod is more prone to shaking. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a stable support bracket to solve the technical problem in the prior art where the main rod only contacts the inside of the connecting seat, and the top of the main rod is prone to shaking.

[0006] This utility model provides a stable support frame, comprising:

[0007] Main shaft;

[0008] A sleeve is fitted onto the main rod, and at least a portion of the sleeve along the axial direction of the main rod is in contact with the outer wall of the main rod;

[0009] The connecting seat is sleeved on the sleeve;

[0010] The support leg has one end rotatably connected to the connecting seat and the other end is a free end. The support leg can be extended or retracted to the main rod.

[0011] A base is provided at one end of the main rod, and when the support leg is retracted, the free end of the support leg is close to the base;

[0012] When the support leg is extended to its maximum angle, the portion of the sleeve that is in contact with the main rod abuts against the base; when the support leg is retracted to the main rod, the portion of the sleeve that is in contact with the main rod separates from the base.

[0013] Optionally, the length of the portion of the sleeve that contacts the main rod along the axial direction of the main rod is greater than the length of the connecting seat along the axial direction of the main rod.

[0014] Optionally, a clamping member is provided at the end of the main rod facing away from the base, and the clamping member is used to clamp external electronic devices;

[0015] The sleeve includes an upper sleeve and a lower sleeve. The lower sleeve fits against the outer wall of the main rod, and a receiving gap is left between the upper sleeve and the main rod to accommodate the clamping member.

[0016] Optionally, the upper sleeve and the lower sleeve are integrally formed.

[0017] Optionally, the connecting seat is sleeved on the lower sleeve, and one end is connected to the upper sleeve.

[0018] Optionally, a screw post is provided on the side of the upper sleeve facing the connecting seat, and a connecting hole is provided on the connecting seat. The connecting hole and the screw post are coaxial, and a bolt is provided at the connecting hole. The bolt extends into the connecting hole and the screw post in sequence and is threadedly connected to the connecting seat and the screw post.

[0019] Optionally, the connector has a connecting groove, the connecting hole and the connecting groove are connected, and the screw post extends into the connecting groove.

[0020] Optionally, it also includes a reinforcing part, wherein the reinforcing part is integrally formed with the outer wall of the upper sleeve on the side facing the upper sleeve, and the reinforcing part is integrally formed with the outer wall of the lower sleeve on the side facing the lower sleeve;

[0021] The connecting seat has a clearance groove, and the reinforcing part is located in the clearance groove.

[0022] Optionally, it also includes a support rod and a locking mechanism, one end of the support rod being rotatably connected to the support foot, and the other end being rotatably connected to the base;

[0023] When the support leg is retracted, the locking mechanism is used to restrict the free end of the support leg from moving away from the main rod. The locking mechanism includes:

[0024] A first magnetic suction element is disposed on the support leg;

[0025] The second magnetic component is disposed on the support rod. When the support leg is retracted, the first magnetic component and the second magnetic component are attracted and fixed together.

[0026] Optionally, it also includes:

[0027] An unlocking mechanism, comprising an unlocking button, wherein the unlocking button is disposed on a base and the side of the unlocking button is an inclined surface;

[0028] An elastic element is disposed between the unlock button and the base;

[0029] When the support leg is retracted, the inclined surface of the unlock button approaches the free end of the support leg; when the unlock button is triggered, the unlock button moves, causing the inclined surface of the unlock button to press against the free end of the support leg, and the free end of the support leg moves away from the main rod, releasing the restriction of the locking mechanism;

[0030] When the unlock button moves toward the main rod under the action of an external force, the elastic element is compressed, and a restoring force is generated that causes the unlock button to move away from the main rod.

[0031] The technical solution of this utility model has the following advantages:

[0032] 1. The stable support bracket provided by this utility model has a sleeve, with at least a portion of the sleeve in contact with the outer wall of the main rod. When the support leg is extended to its maximum angle, the part of the sleeve in contact with the main rod will abut against the base, thereby ensuring that the part of the sleeve in contact with the main rod has sufficient length. This ensures that when the main rod is fully extended (i.e., in use), the entire distance from the base upwards on the main rod is in contact with the sleeve. Compared to the main rod only being in contact with the connecting seat, this solution forms a longer contact surface between the main rod and the sleeve from the base, rather than a contact point. This effectively prevents the top section of the main rod from shaking during use and improves the stability of the top of the main rod.

[0033] 2. The stable support legs provided by this utility model can be moved by triggering the unlock button with external force. The inclined surface of the moving unlock button can continuously squeeze the free ends of the support legs, causing all the free ends of the support legs to move away from the main rod, thereby releasing the restriction of the locking mechanism and putting all the support legs in an unfolded or unfoldable state. Compared with manually unlocking and locking the mechanism one by one, it is more time-saving and labor-saving, and the operation is more convenient and easy, requiring only external force to trigger the unlock button.

[0034] 3. The stable support leg provided by this utility model, by setting an elastic element, when the unlock button releases the restriction of the locking mechanism and the external force is removed, the compressed elastic element has elastic deformation, thereby driving the unlock button to move away from the main rod until the unlock button returns to its initial position. The unlock button can be restored without the assistance of external force, making the operation convenient. In the process of opening the support leg of this application, the unlock button at the lower end of the main rod is generally directly allowed to hit the ground. During the process of the unlock button returning to its initial position, the unlock button is always in contact with the ground. Under the action of the elastic element, the base and the main rod will be lifted up to a certain height (this height is the deformation length of the elastic element). When the support leg encounters a large friction force on the ground and is hindered from unfolding, due to the contact between the sleeve and the base, the main rod rises, which can simultaneously lift the sleeve and the support leg to a certain height to get away from the friction resistance on the ground, allowing the support leg to continue to unfold and assisting the support leg to unfold to the optimal state.

[0054] Example

[0055] Reference Figures 1-11 As shown, this utility model provides a stable support frame, including a main rod 1, a sleeve 4, a connecting seat 2, a support foot 3, and a base 5. The main rod 1 is a straight rod, the sleeve 4 is annular and sleeved on the main rod 1, the sleeve 4 and the main rod 1 are coaxially arranged, the sleeve 4 can slide on the main rod 1 along its length direction, at least a portion of the sleeve 4 along the axial direction of the main rod 1 is in contact with the outer wall of the main rod 1, the connecting seat 2 is annular and sleeved on the sleeve 4, the connecting seat 2 and the sleeve 4 are connected, the connecting seat 2 and the sleeve 4 are coaxially arranged; one end of the support foot 3 is rotatably connected to the bottom wall of the connecting seat 2, and the other end is a free end, the support foot 3 can be unfolded or retracted on the main rod 1, and the base 5 is located at the end of the main rod 1.

[0056] When the support leg 3 is retracted, it is attached to the outer surface of the main rod 1 and parallel to the main rod 1. The free end of the support leg 3 is close to the base 5, and the part of the sleeve 4 that is attached to the main rod 1 is separated from the base 5. There is a certain distance between the sleeve 4 and the base 5. During the unfolding process of the support leg 3, the sleeve 4 moves downward and the free end of the support leg 3 continues to move away from the main rod 1 until the rotation angle of the support leg 3 and the connecting seat 2 reaches the maximum, forming a support structure. When the support leg 3 is unfolded to the maximum angle, the part of the sleeve 4 that is attached to the main rod 1 abuts against the base 5.

[0057] By setting a sleeve 4, with at least a portion of the sleeve 4 in contact with the outer wall of the main rod 1, when the support leg 3 is extended to its maximum angle, the portion of the sleeve 4 in contact with the main rod 1 will abut against the base 5. This ensures that the portion of the sleeve 4 in contact with the main rod 1 has sufficient length, so that when the main rod 1 is fully extended (i.e., in use), the entire distance from the base 5 upwards on the main rod 1 is in contact with the sleeve 4. Compared to the main rod 1 only being in contact with the connecting seat 2, this solution forms a longer contact surface between the main rod 1 and the sleeve 4 starting from the base 5, rather than a contact point. This effectively prevents the top section of the main rod 1 from shaking during use and improves the stability of the top of the main rod 1.

[0058] For at least a portion of the sleeve 4 along the axial direction of the main rod 1 to be in contact with the outer wall of the main rod 1, the contact is not limited to direct contact with the main rod 1, but also includes a small gap between the main rod 1 and the sleeve 4. This small gap can ensure that the sleeve 4 can slide smoothly along the length of the main rod 1 and prevent the top of the main rod 1 from shaking. It should also be understood as the sleeve 4 being in contact with the main rod 1. Regarding the support foot 3 being extended to the maximum angle, it refers to the support foot 3 being extended to a state that can stably support the user.

[0059] Preferably, when the support leg 3 is extended to its maximum angle, the length of the part of the sleeve 4 that is in contact with the main rod 1 is the distance from the base 5 to the connecting seat 2.

[0060] As one specific implementation method, refer to Figure 3-7 As shown, a clamping member 8 is provided at the end of the main rod 1 facing away from the base 5. The clamping member 8 is used to clamp external electronic devices. When the support leg 3 is retracted, the sleeve 4 moves to the clamping member 8 to accommodate it, so that the clamping member 8 is not exposed and the external appearance is maintained.

[0061] Specifically, the sleeve 4 includes an upper sleeve 41 and a lower sleeve 42, which are coaxially arranged. The lower sleeve 42 is located on the side of the upper sleeve 41 facing the base 5. The cross-sectional area of ​​the upper sleeve 41 is larger than that of the lower sleeve 42. There is a accommodating gap between the upper sleeve 41 and the main rod 1. The accommodating gap can be used to accommodate the clamping member 8. When the support leg 3 is retracted, the sleeve 4 moves to the clamping member 8, so that the clamping member 8 is located in the accommodating gap and the clamping member 8 is hidden. The inner wall of the lower sleeve 42 is in contact with the outer wall of the main rod 1.

[0062] Furthermore, to ensure the stability of the main rod 1, the length of the part of the sleeve 4 that is in contact with the main rod 1 along the axial direction of the main rod 1 is greater than the length of the connecting seat 2 along the axial direction of the main rod 1. Specifically, the length of the lower sleeve 42 along the axial direction of the main rod 1 is greater than the length of the connecting seat 2 along the axial direction of the main rod 1, so that the area of ​​the lower sleeve 42 in contact with the main rod 1 is much larger than the inner wall area of ​​the connecting seat 2. Compared with the main rod 1 only being in contact with the connecting seat 2, this solution forms a long contact surface between the main rod 1 and the lower sleeve 42, rather than a contact point, which effectively prevents the top section of the main rod 1 from shaking during use and improves the stability of the top of the main rod 1.

[0063] Furthermore, the upper sleeve 41 and the lower sleeve 42 are integrally formed, which eliminates the assembly link between the upper sleeve 41 and the lower sleeve 42, avoids the error during the assembly of the upper sleeve 41 and the lower sleeve 42, reduces the number of parts of the support leg 3 frame, improves the assembly efficiency of the support leg 3 frame, simplifies the production process, and reduces costs.

[0064] As one specific implementation method, refer to Figure 4 and 5As shown, the connecting seat 2 is sleeved on the lower sleeve 42 and is located on the side wall of the lower sleeve 42 facing the upper sleeve 41. The end of the connecting seat 2 facing the upper sleeve 41 is connected to the upper sleeve 41.

[0065] Specifically, the connecting seat 2 and the upper sleeve 41 are detachably connected, which facilitates the installation and removal of the connecting seat 2. Furthermore, a screw post 6 is integrally formed on the side of the upper sleeve 41 facing the connecting seat 2. The screw post 6 extends along the length of the upper sleeve 41. The connecting seat 2 is provided with a corresponding connecting hole 7. When the connecting seat 2 is fitted onto the lower sleeve 42, the connecting hole 7 and the screw post 6 are coaxially arranged. A bolt is provided at the connecting hole 7. The bolt extends into the connecting hole 7 and the screw post 6 in sequence and is threadedly connected to the screw post 6 of the connecting seat 2, thereby fixing the connecting seat 2 on the upper sleeve 41. During assembly, it is only necessary to remove the bolt and rotate the bolt to screw the bolt into the connecting hole 7 and the screw post 6 in sequence to achieve installation.

[0066] Furthermore, the connecting seat 2 has a connecting groove 9 on the side facing the upper sleeve 41. The connecting hole 7 is located at the bottom of the connecting groove 9 and is connected to the connecting groove 9. When the connecting seat 2 is assembled onto the sleeve 4, the screw post 6 extends into the connecting groove 9 and fits against the inner wall of the connecting groove 9, making the screw post 6 and the connecting hole 7 coaxial. At this time, the connecting groove 9 can accommodate the screw post 6, preventing it from being exposed, and can also position and guide the screw post 6, so that the screw post 6 and the connecting hole 7 correspond during installation, without the need for manual alignment of the connecting hole 7 and the screw post 6. At the same time, when the screw post extends into the connecting groove 9, the connecting seat 2 cannot rotate on the sleeve 4. When installing the bolt, there is no need to manually restrict the rotation of the connecting seat 2 to ensure that the screw post 6 and the connecting hole 7 are always aligned, making assembly faster and more convenient.

[0067] In addition, a side wing 10 is connected to the side wall of the screw post 6. The side wing 10 is set on the side wall of the screw post 6 facing the upper sleeve 41. There are two side wings 10, which are symmetrically arranged about the screw post 6. The side wing 10 facing the upper sleeve 41 is integrally formed with the upper sleeve 41, and the side facing the screw post 6 is integrally formed with the screw post 6. By setting the side wings 10, a strengthening effect can be achieved to prevent the screw post 6 from bursting.

[0068] As another implementation method, refer to Figure 5 and Figure 6As shown, it also includes a reinforcing part 11, which is provided on the end of the upper sleeve 41 facing the lower sleeve 42. The side of the reinforcing part 11 facing the upper sleeve 41 is integrally formed with the outer wall of the upper sleeve 41, and the side of the reinforcing part 11 facing the lower sleeve 42 is integrally formed with the outer wall of the lower sleeve 42. By providing the reinforcing part 11, the connection between the upper sleeve 41 and the lower sleeve 42 can be strengthened. In order to accommodate the reinforcing part 11, the connecting seat 2 is provided with a relief groove 12. When the connecting seat 2 is assembled onto the sleeve 4, the reinforcing part 11 is located in the relief groove 12.

[0069] As one specific implementation method, refer to Figure 6 and Figure 7 As shown, in order to achieve a rotatable connection between the support leg 3 and the connecting seat 2, a rotating seat 13 is integrally formed on one end of the connection between the support leg 3 and the connecting seat 2. Rotating shafts 15 are connected to both sides of the rotating seat 13. A receiving groove 14 is opened on the side of the connecting seat 2 facing the support leg 3. The receiving groove 14 penetrates the side wall of the connecting seat 2 facing and backing the sleeve 42. A rotating groove 16 corresponding to the rotating shaft 15 is opened on the connecting seat 2. The rotating groove 16 is located on the inner side wall of the receiving groove 14. When assembling, the rotating seat 13 is placed in the receiving groove 14 and the rotating shaft 15 is located in the rotating groove 16. At this time, the rotating shaft 15 can rotate along its axis in the rotating groove 16, thereby driving the support leg 3 to rotate, thus achieving a rotatable connection between the support leg 3 and the connecting seat 2.

[0070] In this embodiment, the number of support feet 3 is set to three, but it is not limited to only three; it can also be four, five, or other numbers.

[0071] As another implementation method, refer to Figure 8-11 As shown, the support frame also includes a support rod 17 and a locking mechanism 18. The support rod 17 is located between the support foot 3 and the main rod 1. One end of the support rod 17 is rotatably connected to the support foot 3, and the other end is rotatably connected to the base 5. When the support foot 3 is extended, the support rod 17 is also extended laterally between the base 5 and the support foot 3, thereby improving the stability of the support frame. When the support foot 3 is retracted, the support rod 17 is also retracted onto the outer wall of the main rod 1 and covered by the support foot 3.

[0072] In this embodiment, the number of support rods 17 is also set to three, but it is not limited to only three. It can also be four, five or other numbers, as long as they correspond to the support feet 3.

[0073] When the support leg 3 is retracted, the locking mechanism 18 restricts the free end of the support leg 3 from moving away from the main rod 1. Specifically, the locking mechanism 18 includes a first magnetic attractor 181 and a second magnetic attractor 182. The first magnetic attractor 181 and the second magnetic attractor 182 are set as magnets that can attract each other. The first magnetic attractor 181 is set on the support leg 3, specifically on the side wall of the support leg 3 facing the main rod 1. The second magnetic attractor 182 is set on the support rod 17. When the support leg 3 is retracted, the first magnetic attractor 181 and the second magnetic attractor 182 are attracted and fixed. By setting the first magnetic attractor 181 and the second magnetic attractor 182, a contactless locking method can be achieved. The locking mechanism 18 has a simple and reliable structure. When unlocking, only a certain external force needs to be applied to overcome the magnetic attraction to unlock. It is responsive and has little wear, which greatly improves the life and ease of operation of the locking mechanism 18.

[0074] Furthermore, to facilitate the installation of the first magnetic component 181 and the second magnetic component 182, both the support foot 3 and the support rod 17 are provided with storage slots 183. The first magnetic component 181 and the second magnetic component 182 are placed and adhered in their respective storage slots 183. The storage slots 183 on the support foot 3 are located on the side wall facing the main rod 1 at the end of the support foot 3 away from the connecting seat 2. The storage slots 183 on the support rod 17 are located on the side wall near the base 5. When the support foot 3 is retracted, the storage slots on the support rod 17 are... The storage slots 183 on the support feet 3 and 183 are aligned, so that the first magnetic 181 and the second magnetic 182 can be attracted and fixed to each other. The storage slots 183 provide a stable installation position and protection position for the first magnetic 181 and the second magnetic 182, effectively preventing the first magnetic 181 and the second magnetic 182 from falling off or shifting during transportation or collision. At the same time, the storage slots 183 can also provide positioning for the installation of the first magnetic 181 and the second magnetic 182, making it convenient to install the first magnetic 181 and the second magnetic 182.

[0075] As another implementation method, refer to Figure 10 and Figure 11 As shown, it also includes an unlocking mechanism 19, which includes an unlocking button 191. The unlocking button 191 is mounted on the base 5, and the side of the unlocking button 191 facing the support leg 3 is set as an inclined surface. When the support leg 3 is retracted, the inclined surface of the unlocking button 191 is close to the free end of the support leg 3 and fits against the side wall of the free end. When the unlocking button 191 is triggered, the unlocking button 191 moves, causing the inclined surface of the unlocking button 191 to press against the free end of the support leg 3. The free end of the support leg 3 moves away from the main rod 1, releasing the restriction of the locking mechanism 18. At this time, the support leg 3 is no longer restricted by the locking mechanism 18. When the connecting seat 2 is moved downward, the support leg 3 can be easily unfolded.

[0076] By triggering the unlock button 191 with external force, the unlock button 191 can be pushed to move. The inclined surface of the moving unlock button 191 can continuously squeeze the free end of the support leg 3, causing all the free ends of the support legs 3 to move away from the main rod 1, thereby releasing the restriction of the locking mechanism 18. At this time, all the support legs 3 are in an unfolded or unfoldable state. Compared with manually unlocking the locking mechanism 18 one by one, it is more time-saving and labor-saving, and the operation is more convenient and easy. Only external force is needed to trigger the unlock button 191.

[0077] Furthermore, the unlocking mechanism 19 also includes an elastic element 192, which is disposed between the unlocking button 191 and the base 5. When the unlocking button 191 moves toward the main rod 1 under the action of an external force, the elastic element 192 is compressed and generates a restoring force that causes the unlocking button 191 to move away from the main rod 1. Specifically, the base 5 is provided with a placement groove 193, which is disposed on the end of the base 5 facing away from the main rod 1. One end of the unlocking button 191 is connected to the placement groove 193. Specifically, one end of the unlocking button 191 extends into the placement groove 193 and can slide along the groove depth of the placement groove 193. When the unlocking button 191 is triggered, the unlocking button 191 can move toward the main rod 1, thereby causing the inclined surface of the unlocking button 191 to press against the free end of the support foot 3, causing the free end of the support foot 3 to move away from the main rod 1 and release the restriction of the locking mechanism 18.

[0078] In this embodiment, the unlock button 191, located outside the placement groove 193, receives external stimulation to move. An elastic element 192 is disposed within the placement groove 193, with one end abutting against the bottom of the groove. The end of the unlock button 191 within the placement groove 193 abuts against the other end of the elastic element 192. In this embodiment, the elastic element 192 can be a spring, a sheet, or other elastic structure; no single limitation is imposed.

[0079] By setting the elastic element 192, when the unlock button 191 releases the restriction of the locking mechanism 18 and the external force is removed, the compressed elastic element 192 has elastic deformation, which can drive the unlock button 191 to move away from the main rod 1 until the unlock button 191 returns to the initial position. The unlock button 191 can be restored without the assistance of external force, making the operation convenient. In the process of opening the support leg 3 frame of this application, the unlock button 191 at the lower end of the main rod 1 is usually directly allowed to hit the ground. During the process of the unlock button 191 returning to the initial position, the unlock button 191 is always in contact with the ground. Under the action of the elastic element 192, the base 5 and the main rod 1 will be lifted to a certain height (this height is the deformation length of the elastic element 192). When the support leg 3 encounters a large friction force on the ground and is hindered from unfolding, since the sleeve 4 is in contact with the base 5, the main rod 1 rises, which can bring the sleeve 4 and the support leg 3 to rise to a certain height simultaneously to get away from the friction resistance on the ground, so that the support leg 3 can continue to unfold and assist the support leg 3 to unfold to the optimal state.

Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
