Description

Technical Field

[0001] This utility model belongs to the technical field of photographic auxiliary equipment, and in particular relates to a support frame and a selfie stick. Background Technology

[0002] Chinese patent CN102734765B discloses a "Tripod Support Structure and Lighting Fixture Using the Tripod Support Structure," which involves moving a movable ring along the axis of a sliding rod, thereby opening or closing the support legs via a linkage rod. This allows the support legs to be stably and firmly supported on the ground at a certain height, providing support for the lighting fixture. However, when the lighting fixture is not needed for support, the position of the movable ring on the sliding rod must be adjusted, making the operation relatively cumbersome. The switching between the closed and extended support states is not automatic, and its appearance is not aesthetically pleasing. Furthermore, it cannot maintain the closed state and may enter the extended support state at any time during use. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a support frame and a selfie stick, which can automatically retract and unfold for support, and can stably maintain the retracted state to prevent it from unfolding arbitrarily.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a support frame, comprising:

[0005] The outer tube has a hollow interior that forms a receiving cavity;

[0006] The telescopic inner tube assembly is axially movable to the outer tube;

[0007] Support legs are rotatably connected to the outside of the outer tube. When multiple support legs are retracted towards the outer tube, they fit together to cover the outer tube.

[0008] Connecting seat, used for rotatably connecting the support leg;

[0009] The connecting rod is rotatably connected at both ends to the support leg and the outer tube, respectively;

[0010] A push button, elastically connected to the bottom of the support frame, is used to drive the support legs to open away from the outer tube; it also includes:

[0011] A locking unit is used for locking and unlocking the telescopic inner tube assembly. In the unlocked position, the telescopic inner tube assembly can move axially relative to the outer tube. In the locked position, the positions of the telescopic inner tube assembly and the outer tube are determined, and the receiving cavity is not completely filled by the telescopic inner tube assembly to provide space for the axial movement of the push button.

[0012] The retraction locking unit includes multiple magnetic components embedded in the wall thickness of the support legs. When the support legs are retracted, the magnetic components of adjacent support legs are attracted to each other, so that the support legs remain in the retracted state.

[0013] When the support frame of this utility model is lifted upwards, the support legs can automatically retract under the action of gravity. Moreover, under the action of the retraction locking unit, adjacent support legs are firmly attracted and will not unfold at will, thus keeping the support frame in the retracted state, making it convenient to hold and use as a selfie stick. At the same time, when the bottom end of the telescopic inner tube assembly fills the bottom of the receiving cavity, even if the support frame is pressed against the ground, it cannot unfold and can also effectively maintain the retracted state, making it more stable to use. When the locking unit locks the telescopic inner tube assembly and the outer tube, pressing the bottom of the support frame against the ground will automatically open the support legs. The operation is quick and effortless, and multiple support legs form a stable triangular support structure.

[0014] Furthermore, the locking unit is located between the connecting seat and the telescopic inner tube assembly. The positioning of the locking unit makes operation more convenient.

[0015] Furthermore, the locking unit is a collar made of elastic material, the smallest inner diameter of which is smaller than the outer diameter of the telescopic inner tube assembly. The collar, made of elastic material, can utilize its own deformation to create frictional resistance against the telescopic inner tube assembly, allowing it to stably remain in the locked position. Once an external force is applied to pull the outer tube and the telescopic inner tube assembly, it can enter the unlocked position. This design is simple and reduces manufacturing costs.

[0016] Furthermore, the push button has an inclined driving surface, and the lower end of the support foot is provided with a beveled surface that can abut against the inclined driving surface; the magnetic attractor is positioned close to the beveled surface. The cooperation between the inclined driving surface and the beveled surface can effectively drive the movement of the support foot, while the proximity of the magnetic attractor to the beveled surface ensures that the support foot attracted by the magnetic attractor can unfold outward.

[0017] Furthermore, the retractable locking unit also includes a concave-convex positioning structure located near the magnetic attractor, which has an inclined guide surface. The inclined guide surface can effectively guide adjacent support legs to move along a preset path and accurately engage, avoiding misalignment.

[0018] Furthermore, the number of the concave and convex positioning structures is multiple, and they are distributed at intervals along the axial direction of the support foot. The arrangement of multiple concave and convex positioning structures ensures that the support foot can be correctly assembled as a whole even when the axial length is large, avoiding misalignment.

[0019] Furthermore, the concave-convex positioning structure includes a frustoconical protrusion on the wall thickness of the support foot and a frustoconical groove on the wall thickness of the adjacent support foot. The frustoconical protrusion can fall into and fill the frustoconical groove. The frustoconical protrusion and the frustoconical groove cooperate to prevent axial, circumferential, and thickness-direction offset between adjacent support feet when they are joined, thus avoiding misalignment. Moreover, due to the presence of the inclined guide surface, when adjacent support feet are close but not yet fully joined, the frustoconical protrusion and the frustoconical groove provide good guidance, guiding the adjacent support feet to move along the correct path, ensuring effective joining, and also facilitating the accurate adsorption of the magnetic components of adjacent support feet. Furthermore, the locking unit includes a lock hole in the telescopic inner tube assembly and an unlocking component movably connected to the connecting seat. The unlocking component has a protrusion that can fall into the lock hole and an elastic element opposite to the protrusion. Applying external force drives the unlocking component to move relative to the connecting seat, allowing the protrusion to disengage from the lock hole and enter the unlocked position. The locking unit has a reasonable structural design. It can be unlocked by pressing and can automatically enter the locked position. It is easy to operate and the locking is stable and effective.

[0020] Furthermore, the push button is fitted with an elastic reset member, which pushes the push button axially away from the outer tube.

[0021] This utility model also discloses a selfie stick, including the above-mentioned support frame and a clamping member disposed at the end of the telescopic inner tube assembly.

[0022] Furthermore, the number of support legs is three; a receiving space for accommodating the clamping component is formed within the support frame.

[0023] The beneficial effects of this utility model are as follows: When the support frame is lifted upwards, the support legs can automatically retract under the action of gravity. Moreover, under the action of the retraction locking unit, adjacent support legs are firmly attracted and will not unfold at will, thus keeping the support frame in the retracted state, making it convenient to hold and use as a selfie stick. When the bottom end of the telescopic inner tube assembly fills the bottom of the receiving cavity, even if the support frame is pressed against the ground, it cannot unfold and can effectively maintain the retracted state, making it more stable to use. When the locking unit locks the telescopic inner tube assembly and the outer tube, pressing the bottom of the support frame against the ground will automatically open the support legs, which is quick and effortless to operate. Multiple support legs form a stable triangular support structure. In the retracted state, the support legs cover the outer tube, and the overall shape is simple and beautiful. The clamping parts can be housed in the receiving space, and the overall storage structure is simple, providing a good user experience. Attached Figure Description

Detailed Implementation

[0041] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0042] like Figure 1 , Figure 2 As shown, a support frame includes an outer tube 1 with a hollow interior forming a receiving cavity 11, a telescopic inner tube assembly 2 axially movably connected to the outer tube 1, a support foot 3 rotatably connected to the outside of the outer tube 1, a connecting seat 5 for rotatably connecting the support foot 3, a connecting rod 4 rotatably connected at both ends between the support foot 3 and the outer tube 1, a push button 6 elastically connected to the bottom end of the support frame, a locking unit 7 for locking and unlocking the telescopic inner tube assembly 2, and a retractable locking unit 8 for keeping the support foot 3 in a retracted state.

[0043] There are multiple support legs 3. When the multiple support legs 3 are retracted towards the outer tube 1, they overlap and cover the outer tube 1. That is, in the retracted state, the outer tube 1 is not exposed in the field of vision. Figure 2 As shown, at this time, the bottom end of the telescopic inner tube assembly 2 is located at the bottom of the receiving cavity 11, and the receiving cavity 11 is completely filled by the telescopic inner tube assembly 2. The push button 6 is used to drive the support leg 3 to open away from the outer tube 1, thereby switching the support frame from the retracted state to the extended support state. When the receiving cavity 11 is completely filled by the telescopic inner tube assembly 2, the push button 6 has no room to move upward, so it cannot effectively push the support leg 3 from the retracted state to the extended support state.

[0044] When the locking unit 7 is in the unlocked position, the telescopic inner tube assembly 2 can move freely axially relative to the outer tube 1. Axial direction refers to the vertical direction shown in the diagram, which is also the length direction of the outer tube 1. When in the locked position, the positions of the telescopic inner tube assembly 2 and the outer tube 1 are determined, i.e., they are locked. At this time, the receiving cavity 2 is not completely filled by the telescopic inner tube assembly 2. Figure 7 As shown, this provides sufficient space for the axial upward movement of the push button 6, which can effectively push the support leg 3 from the retracted state to the extended support state. In this embodiment, the locking unit 7 is disposed between the connecting seat 5 and the telescopic inner tube assembly 2. Of course, in other embodiments, it can also be disposed in other positions, and there is no specific limitation.

[0045] Specifically, such as Figure 3 , 4 As shown in Figures 8, 10, and 11, the locking unit 7 includes a locking hole 71 disposed in the telescopic inner tube assembly 2, and an unlocking member 72 movably connected to the connecting seat 5. The unlocking member 72 has a protrusion 721 that can fall into the locking hole 71, and an elastic member 722 disposed opposite to the protrusion 721. When an external force is applied to drive the unlocking member 72 to move relative to the connecting seat 5, the protrusion 721 can disengage from the locking hole 71 and enter the unlocked position, at which time the elastic member 722 is in a compressed state. Once the protrusion 721 moves to the position of the locking hole 71, under the reset action of the elastic member 722, it can automatically fall into the locking hole 71, that is, in the locked state, the protrusion 721 extends into the locking hole 71, as shown in Figures 8, 10, and 11. Figure 10 As shown.

[0046] Of course, such as Figures 14-16 As shown, the locking unit 7 can also be a collar 73 made of elastic material, which is a hollow cylinder, fitted inside the connecting seat 5, and its inner diameter is smaller than the outer diameter of the telescopic inner tube assembly 2. Of course, if the inner wall of the collar 73 has a protrusion or other structure, its minimum inner diameter is smaller than the outer diameter of the telescopic inner tube assembly 2. In this embodiment, the collar 73 can be made of silicone. Utilizing the deformable nature of the collar 73, it generates frictional resistance against the outer wall of the telescopic inner tube assembly 2. When an external force is applied between the telescopic inner tube assembly 2 and the outer tube 1 to overcome the frictional resistance, both are in the unlocked position, and the telescopic inner tube assembly 2 can move axially relative to the outer tube 1. When the external force is stopped, both enter the locked position. This frictional resistance allows the telescopic inner tube assembly 2 and the outer tube 1 to remain in a relatively fixed position.

[0047] In this embodiment, the telescopic inner tube assembly 2 includes multiple inner and outer tubes that are fitted together to achieve telescopic movement. A concave blind groove 21 is formed axially, and this blind groove 21 is used to prevent rotation of the multiple inner tubes. The aforementioned locking hole 71 is located in the area of ​​the blind groove 21. Under normal conditions, the protrusion 721 falls into the blind groove 21 and moves up and down along it. At this time, the elastic element 722 is in a compressed state, and the telescopic inner tube assembly 2 moves freely relative to the outer tube 1; that is, the unlocked position is the normal state.

[0048] like Figure 5 , Figure 6 As shown, the retractable locking unit 8 includes multiple magnetic attractors 81 embedded in the wall thickness of the support legs 3. When the multiple support legs 3 are retracted, the magnetic attractors 81 of adjacent support legs 3 are attracted, thereby keeping the support legs 3 in the retracted state.

[0049] like Figure 7 , Figure 9 As shown, the push button 6 has an inclined driving surface 61, which extends inclinedly from the inside out and from top to bottom, taking the illustrated direction as an example. Correspondingly, the lower end of the support leg 3 has a chamfered surface 31, which also extends inclinedly from the inside out and from top to bottom, and the chamfered surface 31 abuts against the inclined driving surface 61. When an external force is applied to press the push button 6 upward, the inclined driving surface 61 can cooperate with the chamfered surface 31 to drive the support leg 3 to unfold outward. In order to ensure that the support leg 3 attracted by the magnetic member 81 can unfold outward, the magnetic member 81 is set close to the chamfered surface 31.

[0050] To achieve automatic downward reset of the push button 6, an elastic reset member 62 is fitted onto the push button 6. This elastic reset member 62 pushes the push button 6 axially away from the outer tube 1. The specific assembly of the elastic reset member 62 can be achieved using existing technology and will not be described in detail here.

[0051] In order to ensure that the magnetic 81 of adjacent support legs 3 can accurately engage when the support legs 3 switch from the unfolded state to the retracted state, the retracting locking unit 8 also includes a concave-convex positioning structure near the magnetic 81. The concave-convex positioning structure has an inclined guide surface 823, which can guide adjacent support legs 3 to engage accurately and avoid misalignment.

[0052] Specifically, such as Figure 6As shown, the concave-convex positioning structure includes a frustum-shaped protrusion 821 with a wall thickness of 3 on the support leg 3, and a frustum-shaped groove 822 with a wall thickness of 3 on the adjacent support leg 3. The frustum-shaped protrusion 821 protrudes outward and its outer sidewall forms the aforementioned inclined guide surface 823. The frustum-shaped groove 822 is recessed inward and its inner sidewall forms the aforementioned inclined guide surface 823. The frustum-shaped protrusion 821 can fall into and fill the frustum-shaped groove 822, that is, the frustum-shaped protrusion 821 and the frustum-shaped groove 822. The shapes and sizes are matched, so that the adjacent support feet 3 will not shift in the axial, circumferential, or thickness directions when they are assembled, thus avoiding misalignment of the adjacent support feet 3. Moreover, due to the presence of the inclined guide surface 823, when the adjacent support feet 3 are close but not yet fully assembled, the frustum-shaped protrusion 821 and the frustum-shaped groove 822 play a good guiding role, guiding the adjacent support feet 3 to move along the correct path, ensuring their effective assembly, and also benefiting the accurate adsorption of the magnetic suction parts 81 of the adjacent support feet 3.

[0053] In this embodiment, there are multiple concave and convex positioning structures, which are distributed vertically at intervals along the axial direction of the support leg 3. At least one concave and convex positioning structure is located near the magnetic suction member 81 at the bottom of the support leg 3. The arrangement of multiple concave and convex positioning structures ensures that the support leg 3 can be correctly assembled as a whole even when the axial length is large, avoiding misalignment.

[0054] The process of using the support frame of this utility model is as follows: Figure 2 In the folded state shown, when the entire support frame is pressed down to the ground, since the cavity 11 is completely filled by the telescopic inner tube assembly 2, the push button 6 has no space to move upward to compress the elastic reset member 62, and thus cannot switch the support leg 3, which is attracted by the folding locking unit 8, from the folded state to the unfolded state.

[0055] Lift the telescopic inner tube assembly 2 upwards and move it until the protrusion 721 moves along the blind groove 21 and falls into the locking hole 71. The locking unit 7 is in the locked position, the positions of the telescopic inner tube assembly 2 and the outer tube 1 are determined, and the telescopic inner tube assembly 2 does not completely fill the receiving cavity 2. Figure 7 As shown, the telescopic inner tube assembly 2 provides sufficient space for the push button 6 to move upward.

[0056] Pressing the entire support frame down onto the ground pushes button 6, compressing the elastic reset piece 62 upwards. The tilting drive surface 61 pushes the inclined cut surface 31 upwards, causing the support legs 3 to overcome the magnetic attraction of the magnetic attractant 81 and unfold outwards. As multiple support legs 3 unfold outwards, the connecting rod 4 lifts the outer tube 1 upwards. The bottom of the support legs 3 is below the horizontal level of button 6. Thus, multiple support legs 3 gradually and automatically open outwards under the action of the connecting rod 4, enabling the support frame to unfold and be used for support. The unfolding range is relatively large. Figure 13 As shown.

[0057] When it is necessary to switch the support frame from the extended support state to the retracted state, lift it upwards, and under the action of gravity, the multiple support legs 3 will automatically retract downwards and inwards.

[0058] A selfie stick includes a support frame with the above-described structure and a clamping member 9 disposed at the end of the telescopic inner tube assembly 2.

[0059] In this embodiment, there are three support feet 3, and a receiving space 91 for accommodating the clamping component 9 is formed inside the support frame. Specifically, a receiving compartment 92 is provided above the connecting seat 5, which increases the internal space. It works with the connecting seat 5 and the support feet 3 to form the receiving space 91, so as to effectively store the clamping component 9 and make the overall structure simpler.

[0060] like Figure 7 As shown, users can hold the tripod and take selfies or other photos while the support leg 3 is in the folded-back state. Figure 13 As shown, users can also switch the support leg 3 to the unfolded state to form a tripod structure, which can be used to shoot on the ground. It has a variety of uses and is convenient and flexible to use.

[0061] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
