Description

Technical Field

[0001] The invention relates to the technical field of support connection of brackets, in particular to a support bracket with a suction cup. Background Art

[0002] With the continuous improvement of living standards, the ranks of photography enthusiasts are growing. Support frames such as gimbal tripods are one of the essential tools for photography enthusiasts. The gimbal tripod is used to fix the shooting equipment to avoid discomfort in the hands or arms caused by long-term holding of the shooting equipment by users, and to ensure the stability of the shooting equipment during shooting, so as to obtain good shooting effects. A tripod is usually used to support the camera in photography. Generally, a tripod can be switched between the unfolded and folded states, and can be used in scenes where it is held by a handle or supported by a bracket. For many indoor activities (such as gyms or dance studios) that require shooting and recording, the best support method is to adsorb the shooting equipment to a wall or mirror, so users need to purchase an additional shooting bracket with an adsorption function. Summary of the invention

[0003] The present invention provides a support frame with a suction cup to expand the support state of the support frame to meet the support needs of users in more shooting scenes.

[0004] The present invention discloses a support frame with suction cups, which comprises a base and a plurality of legs rotatably connected to the base, each of the legs being provided with at least one suction cup along its radial inner side; when the plurality of legs are in a folded and closed state, all the suction cups are in a space enclosed by the plurality of legs.

[0005] In one embodiment, the supporting leg comprises a flexible metal strip, and the flexible metal strip can be bent and shaped at will under the action of external force.

[0006] In one of the embodiments, each of the legs includes a rubber sleeve wrapped around the outside of the flexible metal strip, and the suction cup is arranged on the outer side wall of the rubber sleeve; the suction cup and the rubber sleeve are an integrally-molded structure formed by injection molding.

[0007] In one of the embodiments, the rubber sleeve is provided with a plurality of spaced apart notches along the axial direction of the leg, the notches extend radially outward from the leg to open at the edge of the rubber sleeve, and the notches provide deformation space for the bending change of the flexible metal strip.

[0008] In one of the embodiments, in any one of the legs, the notch groove is symmetrically arranged with respect to the radial direction of the leg.

[0009] In one embodiment, the inner side wall of the notch groove is connected to the outer side wall of the rubber sleeve in an arc-shaped chamfer.

[0010] In one embodiment, multiple legs can rotate relative to the base to a flat state. In the flat state, the inner side walls of the multiple legs are in the same plane, the adsorption surface of the suction cup protrudes from the bottom surface of the base, and the suction cup can adsorb on a support plane.

[0011] In one embodiment, the base includes a seat body and an outer ring. The outer ring is rotatably sleeved on the side circumference of the base. The installation groove is provided on the side circumference of the seat body. The outer ring is provided with a plurality of circumferentially spaced gaps. The number of the installation grooves, the legs, and the gaps are all multiple and equal; the gaps are offset from the installation grooves, and the outer ring limits the maximum unfolding angle of the legs turning outwards; when the outer ring rotates to any gap aligned with the installation groove, the gap provides a swinging space for the legs to continue turning outwards, so that the legs can pass through the gaps and switch to the flat state.

[0012] In one embodiment, on any of the legs, the number of the suction cups is multiple and arranged at intervals along the axial direction of the legs;

[0013] In one embodiment, the maximum lateral width of the suction cup in the radial direction perpendicular to the leg is not greater than the lateral width of the corresponding leg.

[0014] From the above technical solutions, it can be seen that the embodiments of the present invention have at least the following advantages and positive effects:

[0015] The embodiment of the present invention provides a support frame with suction cups. The inner side of the legs is provided with suction cups. When the multiple legs are in a folded and close state, the suction cups are in the space surrounded by the multiple legs, and the adsorption surface is protected; when the inner side of the legs is exposed, the suction cups can adsorb on a support plane, such as a mirror surface, a ceramic tile wall surface, etc., so as to fix the support frame on the support plane, facilitating the user to install the shooting device on the base for use. The support frame with suction cups of the present application has a flexible and variable use state, can adapt to various shooting scenarios, and has strong practicability.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0027] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0028] With reference to Figures 1-3 , the present application provides a support frame 10 with suckers, which includes a base 100 and multiple legs 210 rotatably connected to the base 100. The base 100 is used to directly or indirectly install a shooting device; the multiple legs 210 form a tripod main body 200 for use as a support component. At least one sucker 300 is provided on the inner side of each leg 210 along its radial direction. When the multiple legs 210 are in a folded and closed state, the sucker 300 is located within the space enclosed by the multiple legs 210 ( Figure 1 as shown). When the inner side of the leg 210 is exposed, the sucker 300 can adsorb on a support plane, such as a mirror surface, a ceramic tile wall surface, etc., so as to fix the support frame 10 on the support plane, facilitating the user to install the shooting device on the base 100 for use. The support frame with suckers of the present application has a flexible and variable use state, can adapt to various shooting scenarios, and has strong practicability.

[0029] Preferably, with reference to Figures 1-3 , the base 100 has a first surface 110 and a second surface 120. The first surface 110 is used to install an external photographic component. In one embodiment, the first surface 110 is provided with an installation part 130. The installation part 130 includes a magnetic absorption adapter ring 131. The edge of the magnetic absorption adapter ring 131 is rotatably connected to the first surface 110 through a swing arm 132. The swing arm 132 can swing relative to the base 100, and the magnetic absorption adapter ring 131 synchronously swings relative to the base 100 until the magnetic absorption adapter ring 131 abuts against the outer side wall of the leg 210 ( Figure 1 as shown). Alternatively, the installation part 130 can also be a clamping seat with a telescopic function (not shown in the figure). Optionally, in other embodiments, the installation part 130 can also be a cold shoe seat, a pan-tilt head, a dovetail plate and other structures. Therefore, in the present application, the setting or not of the swing arm 132 and the magnetic absorption adapter ring 131 is not limited.

[0030] Preferably, with reference to Figure 3 and Figure 4, in one embodiment, the leg 210 includes a flexible metal strip 220 that extends along the axial direction of the leg 210. The flexible metal strip 220 can be bent and shaped arbitrarily under the action of an external force by utilizing the ductility and rigidity of the metal, that is, the user can distort and deform the leg 210 arbitrarily and fix it in the required state. Therefore, no matter what state the tripod body 200 is in, the suction cup 300 can be exposed for use on the adsorption plane for support. For example, when the tripod body 200 is in the support state, a part of the support end 212 can be bent and deformed and fixed, so that the suction cup 300 located at the position of the support end 212 adsorbs on the support surface to improve the support stability of the entire support frame 10 in the support state; in addition, the user can also bend and deform different legs individually to flexibly change the support space position of the support frame 10 to adjust the shooting angle of the shooting device; moreover, the leg 210 can also be bent and deformed and wound around a railing for fixed hanging, etc. Therefore, the flexible metal strip 220 greatly increases the flexibility and usage state of the entire support frame 10 to meet and adapt to more shooting needs of users. Optionally, the flexible metal strip 220 can be made of materials such as aluminum and iron with good ductility. It should be noted that in other embodiments, the leg 210 can also be rigid and cannot be bent and deformed arbitrarily and fixed, and the support height of the entire support frame 10 can also be controlled by controlling the swing angle of the leg 210, and the shooting angle can be adjusted by adjusting the spatial position of the mounting portion 130.

[0031] Preferably, with reference to Figure 3 and Figure 4 , in one embodiment, the leg 210 includes a rubber sleeve 230 covering the outside of the flexible metal strip 220. The suction cup 300 is provided on the side wall of the rubber sleeve 230, and the suction cup 300 and the rubber sleeve 230 are an integrally injection-molded structure. If the flexible metal strip 220 is exposed to the air for a long time, it will be corroded and damaged, so the rubber sleeve 230 is used to protect the flexible metal strip 220. Moreover, the rubber sleeve 230 has elasticity. When the flexible metal strip 220 is straightened, the rubber sleeve 230 can fix the flexible metal strip 220 and recover to a certain extent, reducing the damage of the flexible metal strip 220 during the twisting process. Optionally, the flexible metal strip 220 can be detachably inserted into the rubber sleeve 230, so that the rubber sleeve 230 can be conveniently replaced, and thus the suction cup 300 can be replaced. It should be noted that without considering the protection of the flexible metal strip 220, the setting of the rubber sleeve 230 is not limited. Of course, in other embodiments, the suction cup 300 can also be detachably installed on one side of the rubber sleeve 230.

[0032] Preferably, with reference to Figure 3 and Figure 4, in one embodiment, the rubber sleeve 230 is provided with a plurality of notch grooves 240 arranged at intervals along the axial direction of the leg 210. The notch grooves 240 extend radially outward along the leg 210 and open at the edge of the rubber sleeve 230. During the bending deformation of the flexible metal strip 220, the edge of the rubber sleeve 230 is stretched and undergoes elastic deformation. The notch grooves 240 provide a deformation space for the bending change of the flexible metal strip 220, greatly reducing the elastic damage of the rubber sleeve 230. Here, when the user bends the flexible metal strip 220, it is relatively easy and labor-saving, without having to overcome the elastic force of the rubber sleeve 230 to bend and deform the flexible metal strip 220. Further, preferably, the notch grooves 240 are symmetrically arranged relative to the radial direction of the leg 210 to enhance the bending flexibility of the flexible metal strip 220. It should be noted that in this application, whether the notch grooves 240 are provided or not is not limited; the setting state of the notch grooves 240 is also not limited.

[0033] Preferably, in one embodiment, with reference to Figure 3 and Figure 4 , the inner side wall of the notch groove 240 is connected to the outer side wall surface of the rubber sleeve 230 by an arc chamfer, that is, smoothly connected. This effectively reduces the cutting feeling of the entire leg and improves the user's comfort in using the entire support frame 10 (such as the comfortable feeling of holding, or the comfortable feeling during the operation of bending the leg 210, etc.); on the other hand, the smooth connection between surfaces can also increase the smoothness of the lines and the aesthetic appearance of the entire support frame 10. It should be noted that without considering the comfort or aesthetics of the entire support frame 10, whether the inner side wall of the notch groove 240 is connected to the outer side wall of the rubber sleeve 230 by an arc chamfer is not limited.

[0034] Preferably, with reference to Figures 1-3 , in one embodiment, in one embodiment, if the leg 210 is made of a rigid material and cannot be bent and deformed, in order to realize the adsorption function of the suction cup 300, multiple legs 210 can be rotated relative to the base 100 to a flat state. In the flat state, the inner side walls of multiple legs 100 are in the same plane, and the adsorption surface of the suction cup 300 protrudes from the bottom surface of the base 100 (i.e., the second surface 120). The suction cup 300 can adsorb on the support plane. When the suction cup 300 adsorbs on the plane, the second surface 120 is lower than the adsorption surface of the suction cup 300 and will not produce a convex feeling to affect the adsorption function of the suction cup 300. Optionally, the leg 210 here can be made of a flexible metal strip 220 ( Figure 4 shown), whether the leg 210 can be rotated to a flat state is not limited; the leg can also be made of a non-bendable rigid material, and the suction cup 300 is used to adsorb and support the plane through the flat state.

[0035] Specifically, the tripod body 200 includes a plurality of legs 210. Each leg 210 has a rotating end 211 and a supporting end 212 that are opposite to each other along its axial direction. The rotating end 211 is rotatably connected to the base 100, and the leg 210 can swing up and down relative to the base 100 to change the angle between the leg 210 and the second surface 120, so that the tripod body 200 can be switched between a handle state, a bracket state, and a laying state. Figure 1 It is shown that the tripod body 200 is in the handle state, and the plurality of legs 210 are in a side-by-side and close-together posture (i.e., in a folded and close-together state). At this time, the user can hold the entire support frame 10 and use it as a selfie stick. Figure 2 It is shown that the tripod body 200 is in the bracket state, and the plurality of legs 210 are in an angular posture. At this time, the user can support the entire support frame 10 on a flat or uneven support surface and use it as a bracket. Figure 3 It is shown that the tripod body 200 is in the laying state, and the plurality of legs 210 are in a scattered and laid-out posture along the side circumference of the base 100. Among them, one or more suction cups 300 are provided on the inner side of each leg 210. In the laying state, the adsorption surface of the suction cup 300 faces away from the first surface 110, and the suction cup 300 can adsorb on the support plane, where the support plane includes but is not limited to a mirror surface, a smooth tabletop, and a wall surface, etc. Optionally, here, the number of legs 210 is at least three, and the support frame 10 is a tripod, which has strong stability in the bracket state; the rotating end 211 is rotatably connected to the edge of the second surface 120, so that the volume of the base 100 tends to be miniaturized.

[0036] Preferably, with reference to Figures 4-6 , in an embodiment, one of the rotating end 211 and the side circumference of the base 100 is provided with a mounting block 213, and the other is provided with a mounting groove 141. The mounting block 213 is limited in the mounting groove 141, and the mounting block 213 can rotate on the inner side wall of the mounting groove 141 and drive the leg 210 to swing, realizing the rotational connection of the rotating end 211 to the base 100. It should be noted that in other embodiments, the mounting groove 141 and the mounting block 213 may not be provided, as long as the structure that can realize the rotational connection of the rotating end 211 to the side of the base 100 should be protected.

[0037] Preferably, with reference to Figures 4-6, in one embodiment, the base 100 includes a base body 140 and an outer ring 150. The outer ring 150 is rotatably sleeved on the side circumference of the base body 140. An installation groove 141 is provided on the side circumference of the base body 140, and a plurality of circumferentially spaced notches 151 are provided on the outer ring 150. The number of the installation grooves 141, the legs 210, and the notches 151 are all multiple and equal. When the notches 151 are misaligned with the installation grooves 141, the outer ring 150 limits the maximum expansion angle of the legs 210 turning outwards; when the outer ring 150 rotates to a position where any notch 151 is aligned with the installation groove 141, the notch 151 provides a swinging space for the legs 210 to continue turning outwards, so that the legs 210 can pass through the notches 151 and switch to the tiled state. Specifically, when the support frame 10 is in the handle state or the support state, the installation grooves 141 and the notches 151 are staggered along the circumferential direction of the base 100, and the outer ring 150 covers the side circumferential opening of the installation groove 141, which can prevent the legs 210 from swinging outwards to the tiled state; when the outer ring 150 rotates to a position where any notch 151 is aligned with the installation groove 141, the notch 151 provides a large enough swinging space for the legs 210, and at this time the legs 210 can swing outwards to the tiled state( Figure 6 ). It should be noted that the mutual cooperation of the base body 140 and the installation groove 141, the outer ring 150 and the notch 151 is a specific way to realize the switching between different states of the tripod main body 200, that is, a specific structural way to control the angle between the legs 210 and the second surface 120 (the expansion angle of the legs 210). In other embodiments, the expansion angle of the legs 210 can also be controlled by the limiting grooves arranged at intervals in the thickness direction of the base 100. Therefore, in this application, the setting or not of the base body 140 and the installation groove 141, the outer ring 150 and the notch 151 is not limited, and as long as it can control the expansion angle of the legs 210 in different ways, the structural way should be protected.

[0038] Preferably, referring to Figure 2 or Figure 3 , in one embodiment, on any leg 210, the number of the suction cups 300 is multiple and arranged at intervals along the axial direction of the leg 210. The multiple suction cups 300 arranged at intervals can increase the adsorption force and improve the adsorption stability. It should be noted that, without considering the adsorption stability, the number of the suction cups 300 on one leg 210 is not limited.

[0039] Preferably, referring to Figure 3, in one embodiment, during the process of the suction cup 300 adsorbing on a plane, it is necessary to press and evacuate, and the diameter of the suction cup 300 will change. The maximum radial dimension of the suction cup 300 is not greater than the radial dimension of the corresponding leg 210, so that the inner side of the leg 210 provides a wide enough mounting surface for the suction cup 300. Such a design enables the suction cups 300 on each leg 210 to adsorb without affecting each other, thereby improving the adsorption effect. It should be noted that without considering the adsorption effect, in this application, the relative radial dimensions of the suction cup 300 and the leg 210 are not limited.

[0040] Although the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be construed broadly within the spirit and scope defined by the appended claims.
