Description

Technical Field

[0001] This utility model relates to photographic and video recording auxiliary equipment, and in particular to a portable stand. Background Technology

[0002] With the development of photography and videography technology, people have increasingly higher requirements for scene setup and shooting angles. In order to meet the needs of shooting and adjusting lighting at different heights and angles, it is usually necessary to set up photography equipment such as photography lights and tripods on support equipment such as tripods and rails.

[0003] Currently, when using a photography tripod, the support legs must first be opened and placed on the ground. After pulling the tripod to a suitable height, the photography equipment is installed. Then, the support legs are stepped on and the lever is pulled to a higher height by hand.

[0004] However, most current camera tripods use metal legs. When open, these legs are positioned with one end grounded and the other connected to the lever, leaving the middle section suspended. Stepping on the legs and pulling the tripod upwards can easily deform or break them, shifting the tripod's center of gravity and affecting its stability. Adding a dedicated footrest at the end of the legs, which rests on the ground, would result in components protruding from the main lever body when the tripod is folded, making it inconvenient to carry. Utility Model Content

[0005] The purpose of this invention is to solve the technical problems in the prior art where the support feet of a photography bracket are prone to deformation or breakage when stepped on, and where there are no protruding components from the rod-shaped main body when the support feet are folded up, thus effectively meeting the requirements for the stability and portability of the photography bracket.

[0006] To solve the above-mentioned technical problems, this utility model provides a portable stand, including: a base tube, which is hollow inside;

[0007] A pull rod assembly includes multiple pull rods, which are movably disposed inside the base tube and are sequentially sleeved and connected; the connected pull rods are movable relative to each other, allowing the pull rods to extend outward from the base tube or retract inward into the base tube, wherein the end of one of the pull rods is used to connect to an external device;

[0008] The support leg assembly includes at least three support legs; each support leg includes a support body and a tension rod disposed on the outer wall of the support body. The support body is a rigid component, and the tension rod is made of a different material from the support body, so that the outer surface of the tension rod undergoes greater elastic deformation relative to the support body when stepped on by a user. One end of the support body is rotatably connected to the base tube, so that the support leg can move away from the base tube, allowing the support leg assembly 30 to open and be supported on a plane of the external environment, or allowing the support leg to move towards the base tube, so that the support leg assembly is retracted to the outside of the base tube.

[0009] In some embodiments, the support body includes a fixed rod and a hinged rod connected together, the tension rod is disposed on one side of the fixed rod, and the hinged rod is connected to the side of the fixed rod opposite to the tension rod; one end of the hinged rod is rotatably connected to the base tube.

[0010] In some embodiments, the support leg assembly further includes a plurality of connecting rods, one end of which is rotatably connected to the base tube, and the other end of which is detachably connected to the other end of the hinge rod opposite to its end connected to the base tube.

[0011] In some embodiments, the base tube includes a tube body and a retainer at the end of the tube body. The retainer has a plurality of hinge slots spaced apart on its periphery. The connecting rod includes a fourth rod body and a hinge shaft at one end of the fourth rod body. The ends of the plurality of connecting rods are rotatably connected to the plurality of hinge slots in a one-to-one correspondence through the hinge shaft.

[0012] In some embodiments, the base tube further includes a collar seat sleeved on the outside of the tube body. The collar seat has a plurality of transition grooves spaced apart on its periphery. Each of the hinge rods includes a first rod body and a pivot shaft disposed at the end of the first rod body. The pivot shafts of the plurality of hinge rods are rotatably connected in the plurality of transition grooves in a one-to-one correspondence.

[0013] In some embodiments, the hinge rod further includes a connecting portion disposed at the end of the first rod body opposite to the pivot shaft, the connecting portion being a hook structure; the main body of the connecting rod is provided with a hanging hole at the end opposite to the hinge shaft, and the connecting portion is detachably connected to the hanging hole.

[0014] In some embodiments, the side of the fixed rod is provided with a sliding groove, and the tension rod is movably disposed in the sliding groove so that the tension rod can move relative to the fixed rod along its own extension direction, and the movement direction of the tension rod relative to the fixed rod is consistent with the extension direction of the tension rod.

[0015] The tension rod has multiple snap-fit ​​components on its side facing the fixing rod, and the multiple snap-fit ​​components are spaced apart along the extension direction of the tension rod; one end of the fixing rod has a slot, and the snap-fit ​​components can be elastically snapped into the slot.

[0016] In some embodiments, the fixed rod has a first receiving groove on the side opposite to the tension rod, the hinge rod is disposed in the first receiving groove, the inner surface of the fixed rod corresponding to the first receiving groove is an arc-shaped surface, and the surface of the hinge rod opposite to the fixed rod is an arc-shaped surface.

[0017] In some embodiments, the pull rod includes a rod body and a buckle disposed at one end of the rod body. The buckle protrudes from the outer wall of the rod body, and the end of the rod body away from the buckle is provided with a locking hole adapted to the buckle. When the plurality of pull rods are stretched outward in a direction away from the base tube, the buckle of one of two adjacent pull rods engages with the locking hole of the other pull rod, so that the plurality of pull rods are fixed in the stretched state.

[0018] In some embodiments, the portable stand further includes an interface, and the plurality of pull rods are stretched outward in a direction away from the base tube, enabling the plurality of pull rods to be in an extended state; among the plurality of pull rods in the extended state, the pull rod farthest from the base tube is the distal pull rod, and the interface is disposed at the end of the distal pull rod, the interface being used to connect to an external device.

[0019] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows: In the portable stand of this utility model, the support leg assembly includes a support body and a tension rod disposed on the outer wall of the support body. The support body is a rigid component, while the tension rod is made of a different material than the support body, such as a flexible component. When using the portable stand of this application, the user first opens the support leg assembly, places their foot on the outer wall of the tension rod to maintain the stability of the stand, and then adjusts the stand to the desired height. The tension rod is made of a flexible component with a low elastic modulus. Although it deforms during the elastic deformation stage, it quickly returns to its original shape after the foot is removed, making the tension rod less prone to deformation by foot pressure and exhibiting good plasticity.

[0020] The support body of the support leg assembly is made of a rigid component with increased elastic modulus. The support body, together with the tension rod, ensures that the support leg has sufficient strength and rigidity when supporting. The good plasticity of the tension rod can buffer and disperse external forces to a certain extent, preventing the support body from deforming due to excessive external forces, ensuring the overall structural strength of the support leg, and effectively enhancing the overall structural stability of the portable bracket.

Detailed Implementation

[0031] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0032] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] See Figures 1 to 4 One embodiment of this application provides a portable stand 100 including a base tube 10, a plurality of pull rods 21 and a support leg assembly 30.

[0035] The base tube 10 is hollow inside. The pull rod assembly 20 includes multiple pull rods 21, which are movably disposed inside the base tube 10 and are sequentially connected. The connected pull rods can move relative to each other, allowing the pull rods to extend outward from the base tube 10 or retract inward into the base tube 10. One end of one pull rod is used to connect to external equipment.

[0036] The foot support assembly 30 includes at least three support legs 31. Each support leg 31 includes a support body 310 and a tension rod 313 disposed on the outer wall of the support body 310. The support body 310 is a rigid component, and the tension rod 313 is made of a different material than the support body, such as a flexible component. The outer surface of the tension rod 313 is used for stepping by the user. One end of the support body 310 is rotatably connected to the base tube 10, so that the support leg 31 can move away from the base tube 10, allowing the foot support assembly 30 to open and be supported on the plane of the external environment, or allowing the support leg 31 to move towards the base tube 10, so that the foot support assembly 30 is retracted to the outside of the base tube 10.

[0037] The portable stand 100 of this application includes a base tube 10, a pull rod assembly 20, and a support leg assembly 30. The base tube 10 has a central control section that can accommodate the pull rod assembly 20. The pull rod assembly 20 extends outward from the base tube 10, allowing the stand to support external equipment at a suitable height. The support leg assembly 30 includes a support body 310 and a tension rod 313. The tension rod 313 is made of a flexible component with a low modulus of elasticity for user stepping. The support body 310 is rotatably connected to the base tube 10, allowing the support leg assembly 30 to open and close. The support body 310 is a rigid component used to support the portable stand 100 of this application.

[0038] In actual use, the user first opens the support leg assembly 30 and places it on a flat surface in the external environment. Then, the user steps on the outer surface of the tension rod 313 to adjust the portable bracket 100 to a suitable height. The tension rod 313 is made of a flexible component; although it deforms when the user steps on it, it quickly returns to its original shape after the foot is removed, making it resistant to deformation and exhibiting good plasticity. The support body 310 of the support leg assembly 30 is made of a rigid component with a higher elastic modulus than the flexible component of the tension rod 313. The support body 310, in conjunction with the tension rod 313, ensures that the support legs 31 have sufficient strength and rigidity when supported. Furthermore, the good plasticity of the tension rod 313 can buffer and disperse external forces to a certain extent, preventing the support body 310 from directly entering the plastic deformation stage due to excessive external force, effectively enhancing the overall structural stability of the portable bracket 100.

[0039] In some embodiments of this application, the base tube 10 is the main structural component of the entire bracket, including a hollow tube body 11, the internal space of which forms a receiving space. This receiving space is used to assemble the pull rod assembly 20, which includes multiple pull rods 21. The multiple pull rods 21 can extend from the receiving space to make the height of the portable bracket 100 adjustable, and the multiple pull rods 21 can be housed in the receiving space of the base tube 10, making it convenient for the user to store and carry the portable bracket 100 when it is not in use.

[0040] Specifically, multiple pull rods 21 are movably disposed inside the tube body 11 of the base tube 10, and the multiple pull rods 21 are sequentially connected. The connected pull rods can move relative to each other, allowing the multiple pull rods 21 to extend outward from the base tube 10 or retract inward into the base tube 10. In use, the multiple pull rods 21 extend outward from the base tube 10, allowing the portable stand 100 to be stretched to a suitable height. When not in use, the multiple pull rods 21 retract into the receiving space inside the base tube 10, allowing the portable stand 100 to be folded up for easy storage and carrying.

[0041] When the multiple tie rods 21 are in the extended state, relative to the base tube 10, the farthest tie rod is the far-end tie rod 211, the closest tie rod is the near-end tie rod 213, and the remaining tie rods other than the far-end tie rod 211 and the near-end tie rod 213 are the middle tie rods 212.

[0042] In some examples, the portable stand 100 also includes an interface 40 disposed at the end of the distal pull rod 211 opposite to the middle pull rod 212. The interface 40 is used to connect an external device, such as a camera, a video light, or a mobile phone. Through the interface 40, the external device can be fixed to the end of the distal pull rod 211 to achieve a stable assembly of the external device on the portable stand.

[0043] The interface component 40 may include an interface body 41 and an extension 42 connected to the interface body 41. The end opening of the distal pull rod 211 is engaged and fixed within the end opening of the interface component 40. The outer wall of the interface body 41 may be threaded to fit the screw hole of an external device, thereby achieving a screwed connection between the interface component 40 and the external device.

[0044] In some examples, a screw hole can be provided on the interface body 41, allowing the external device to be screwed into the screw hole, thereby achieving stable assembly of the external device on the portable bracket 100. In some examples, the interface body 41 can be provided with a slot 3125 that adapts to the slot of the external device, allowing the slot of the external device to be engaged in the slot 3125 of the interface body 41, thereby connecting the external device to the portable bracket 100. In some examples, the interface body 41 can also be a magnetic component, allowing the external device to be magnetically attached to the interface body 41, thereby achieving assembly of the external device with the portable bracket 100.

[0045] In some embodiments of this application, each pull rod of the pull rod assembly 20 includes a rod body 2101 and a buckle 2102 disposed at one end of the rod body 2101. The end of the rod body 2101 away from the buckle 2102 is provided with a locking hole 2103 adapted to the buckle 2102. The buckle 2102 and the locking hole 2103 at the adjacent end of the pull rod cooperate to fix the rod body 2101 in the extended state when it is stretched.

[0046] The pull rod assembly 20 may also include a locking element 22. The locking element 22 is annular and is disposed at the end of the shaft 2101 of the plurality of pull rods 21. A latch 2102 is disposed on the outer wall of the locking element 22 and protrudes from the outer wall of the shaft 2101. In some examples, the latch 2102 may be integrally formed with the locking element 22.

[0047] For the distal pull rod 211, the locking member 22 is connected to the end of the rod body 2101 of the distal pull rod 211 that is away from the interface member 40. The buckle 2102 protrudes from the side wall of the rod body 2101 of the distal pull rod 211. One end of the middle pull rod 212 connected to the distal pull rod 211 is provided with a locking hole 2103. The buckle 2102 on the locking member 22 of the distal pull rod 211 can be locked in the locking hole 2103 at one end of the middle pull rod 212, so that the distal pull rod 211 and its adjacent middle pull rod 212 are stretched into place, and the distal pull rod 211 is fixed in the extended state.

[0048] For multiple middle tie rods 212, the locking member 22 is connected to the end of the middle tie rod 212's body 2101 facing away from the distal tie rod 211, and the end near the distal tie rod 211 is provided with a locking hole 2103. When the tie rod assembly 20 needs to be extended, the latch 2102 of the locking member 22 of one tie rod of two adjacent middle tie rods 212 engages in the locking hole 2103 of the other tie rod, thereby extending the middle tie rod 212 into position and stabilizing and elongating the middle tie rod 212.

[0049] For the proximal pull rod 213, the end of the rod body 2101 near the middle pull rod 212 is provided with a locking hole 2103 that matches the buckle 2102 on the locking member 22 of the middle pull rod 212. The other end of the rod body 2101 of the proximal pull rod 213 is equipped with a base 23. The base 23 has an annular structure, and the outer wall of the base 23 includes a connected flat surface and an arc-shaped surface. The inner wall contour of the tube body 11 of the base tube 10 near the proximal pull rod 213 matches the outer wall contour of the base 23, so that when the proximal pull rod 213 is pulled out relative to the base tube 10, the base 23 and the inner wall of the tube body 11 of the base tube 10 are rigidly engaged to fix the proximal pull rod 213 in the extended state.

[0050] See Figures 5 to 7 The base tube 10 is provided with a support foot assembly 30 on the outside, which enables the portable support 100 to be supported on the ground.

[0051] The support leg assembly 30 includes at least three support legs 31. The design of multiple support legs 31 allows the portable support 100 to be stably supported on a flat surface in the external environment. Each support leg 31 includes a support body 310 and a tension rod 313 disposed on the outer wall of the support body 310. The tension rod 313 is a flexible component. When the user steps on the tension rod 313, it returns to its original shape after the foot is removed, making the tension rod 313 less prone to deformation from being stepped on.

[0052] In this application, the support body 310 is a rigid component. The support body 310 is combined with the tension rod 313. This arrangement ensures that the support leg 31 has sufficient strength and rigidity when supporting, avoids deformation of the support body 310 due to excessive external force, ensures the overall structural strength of the support leg 31, and can effectively enhance the overall structural stability of the portable bracket 100.

[0053] In some embodiments of this application, the support body 310 includes a fixed rod 312 and a hinge rod 311, with a tension rod 313 disposed on the outer wall of the fixed rod 312. The hinge rod 311 includes a first rod body 3111 and a pivot 3112 disposed at one end of the first rod body 3111. In some examples, the base tube 10 may further include a collar seat 12 sleeved on the outside of the tube body 11, with the hinge rod 311 rotatably connected to the collar seat 12.

[0054] Specifically, the collar seat 12 has multiple transition grooves 121 spaced apart around its periphery, and the pivot 3112 of the hinge rod 311 is correspondingly engaged in the transition grooves 121 of the collar seat 12. In use, the pivot 3112 rotates in the transition grooves 121, allowing the support leg 31 to rotate away from the base tube 10 to open the support leg 31, or the support leg 31 to rotate towards the base tube 10 to press against the outer wall of the base tube 10. In some examples, the end of the first rod 3111 opposite to the pivot 3112 has a connecting part 3113, which can be a hook-shaped structure.

[0055] The fixed rod 312 includes a second rod body 3121 and two rod edges 3123 respectively disposed on both sides of the second rod body 3121 and folded upwards. The surface of the second rod body 3121 is provided with a first receiving groove 3122, and the first rod body 3111 of the hinge rod 311 is inserted into the first receiving groove 3122. The two rod edges 3123 and the outer surface of the second rod body 3121 enclose two sliding grooves 3124.

[0056] The tension rod 313 includes a third rod body 3131 and opposing flanges 3132 on the inner surface of the third rod body 3131. The outer surface of the third rod body 3131 facing away from the fixed rod 312 is an arc-shaped surface, and the flanges 3132 of the third rod body 3131 and the arc-shaped surface enclose to form a second receiving groove 3133. The flanges 3132 are inserted into the sliding grooves 3124 of the fixed rod 312, and the first receiving grooves 3122 of the fixed rod 312 are inserted into the second receiving grooves 3133 of the tension rod 313. The hinge rod 311, the fixed rod 312, and the tension rod 313 are interlocked and connected, making the overall structure of the support leg more compact.

[0057] In some embodiments, a protrusion 3114 is provided at one end of the first rod body 3111 near the connecting part 3113. The protrusion 3114 is inserted into the gap formed by the protruding edge 3132 of the tension rod 313 and the slide of the fixed rod 312, which can prevent the fixed rod 312 and the tension rod 313 from disengaging from the connection of the hinge rod 311, making the connection between the hinge rod 311, the fixed rod 312 and the tension rod 313 more stable.

[0058] In the embodiments of this application, the tension rod 313 can be pulled out relative to the fixed rod 312 along its own extension direction. Specifically, the inner surface of the tension rod 313 near the fixed rod 312 is provided with a plurality of mounting grooves 3134 at intervals along its extension direction, and a snap-fit ​​member 3135 is provided in the mounting groove 3134. One end of the fixed rod 312 is provided with a slot 3125, and the snap-fit ​​member 3135 can be snapped into the slot 3125, so that when the tension rod 313 is pulled out relative to the fixed rod 312 along its own extension direction, the tension rod 313 can be fixed in the pulled-out state, thereby extending the support leg, increasing the area occupied by the support leg, and thus making the support more stable.

[0059] In the embodiments of this application, the inner surface of the hinge rod 311 is arc-shaped, so that the support leg 31, after being folded, fits against the outer wall of the base tube 10 body 11, making the portable bracket 100 compact when folded. The surface of the tension rod 313 facing away from the fixed rod 312 is arc-shaped, for the user to step on. The arc-shaped design of the tension rod 313 can, on the one hand, disperse the external force borne by the user's foot, and on the other hand, make the support leg assembly 30 present a complete cylindrical shape when folded, making it convenient for the user to hold and store.

[0060] See Figure 3 The support leg assembly 30 also includes a number of connecting rods 32 equal to the number of support legs 31. The connecting rods 32 include a fourth rod body 321, and one end of the fourth rod body 321 is provided with a hinge shaft 322 for rotatably connecting with the base tube 10.

[0061] Specifically, a retaining seat 13 is fixedly connected to the other end of the base tube 10 away from the pull-out direction of the pull rod. Multiple hinge slots 131 are provided around the retaining seat 13. The hinge shafts 322 of the connecting rod 32 are correspondingly engaged in the hinge slots 131 of the retaining seat 13, allowing the connecting rod 32 to be rotatably connected to the base tube 10. The connecting rod 32, supported between the base tube 10 and the support leg 31, further increases the stability of the support leg 31, thereby making the support structure more stable.

[0062] The fourth rod 321 of the connecting rod 32, away from the hinge shaft 322, has a hanging hole 323 for detachably connecting to the connecting part 3113 of the hinge rod 311. In some embodiments, the hook of the connecting part 3113 of the hinge rod 311 can also be a buckle 2102, a magnetic element, etc., and the structure corresponding to the end of the connecting rod 32 connected to the hinge rod 311 can be a slot 3125, a magnetic element, etc. When the support leg 31 is opened, the connecting rod 32 is connected to the connecting part 3113 of the hinge rod 311 to support the support leg 31. When the support leg 31 is retracted, the connection between the connecting rod 32 and the hinge rod 311 is released, so that the support leg 31 can rotate and retract to the outer wall of the base tube 10.

[0063] See Figure 8 , Figure 9 In some embodiments, the base tube 10's mounting base 13 is composed of a mounting base bottom 1301 and a mounting base cover 1302. The mounting base bottom 1301 and the mounting base cover 1302 are fixedly connected by screws 1303 or other means. The circumferences of the mounting base bottom 1301 and the mounting base cover 1302 are provided with corresponding shaft grooves, which together form a hinge groove 131 that is rotatably connected to the connecting rod 32.

[0064] In some embodiments, the base tube 10 of the portable support 100 further includes a locking ring 14, which is sleeved on the outer wall of the base tube 10. The outer diameter of the locking ring 14 is larger than the outer diameter of the collar seat 12, so that when the support leg assembly 30 is in the retracted state, the locking ring 14 can partially cover the outer periphery of the collar seat 12, thereby restricting the support leg assembly 30 from rotating away from the base tube 10 and preventing the support leg assembly 30 from accidentally rotating open when in the retracted state.

[0065] In actual use, first rotate the locking ring 14 upwards to allow the support leg assembly 30 to rotate outwards and open, supporting it on a flat surface of the external environment. Then, adjust the pull rod to the appropriate length as needed and connect the required equipment to the bracket. Step on the outer surface of the tension rod 313 to keep the bracket stable and continue to stretch the bracket to the required height. At the same time, pull out the tension rod 313 to adjust the length of the support leg 31, increasing the stability of the bracket. After use, first retract the tension rod 313, then disconnect the connection between the hinge rod 311 and the connecting rod 32, rotate the connecting rod 32 upwards to fold it, and the support leg assembly 30 will be folded into the outside of the base tube 10. Retract the pull rod into the base tube 10, and then rotate the locking ring 14 downwards to cover the outside of the collar seat 12, completing the bracket storage.

[0066] In this application, the tension rod 313 is made of a material with a low elastic modulus, which allows the tension rod 313 to undergo a large elastic deformation relative to the support body 310 when the user steps on it, but it quickly returns to its original shape after the foot is removed. The tension rod 313 is not easily deformed by stepping on it, exhibiting good plasticity. The support body 310 of the support leg assembly 30 is made of a rigid component with an increased elastic modulus. The support body 310, together with the tension rod 313, ensures that the support leg 31 has sufficient strength and rigidity when supporting, and the good plasticity of the tension rod 313 can buffer and disperse external forces to a certain extent, avoiding deformation of the support body 310 due to excessive external forces, ensuring the overall structural strength of the support leg 31, and effectively enhancing the overall structural stability of the portable bracket 100.

[0067] In other embodiments of this application, the tension rod 313 can also be a rigid component, such as the support body 310, which can be made of metal (steel, aluminum alloy) or engineering plastic (such as PEEK). The tension rod 313 can be made of a polymer with good toughness (such as TPU, nylon) or a composite material. The tension rod 313 has a smaller elastic modulus, a smaller yield strength, and a higher elongation at break compared to the support body 310, so that the outer surface of the tension rod 313 has greater elastic deformation than the support body 310 when stepped on by a user, and quickly returns to its original shape after the user's foot is removed.
