Description

[Technical field]

[0001] The present invention relates to the field of support devices, and more particularly to fully deployable support legs. [Background technology]

[0002] Support devices are often used to support devices such as projectors, mobile phones, and cameras. A common support structure is a tripod. To facilitate storage, tripods are designed as structures that can be retracted and extended at any time. For example, the prior application of patent application number CN201921123317.9 discloses a support leg in which the support leg is retracted into a stick when not in use, making it easy to carry, and when it needs to be used, the elastic engagement mechanism is pressed and the support leg is slightly extended from the position where it is in close contact with the stick. However, such extension only changes the support leg into an extendable state, and the extension width is very limited, and the support leg needs to be manually rotated to fully extend it.

[0003] Therefore, there is potential for further optimization to solve the problem of the support legs needing to be manually rotated to be fully extended. [Prior art documents] [Patent documents]

[0024] The achievement of the objectives, functional features and advantages of the present invention will be further explained with reference to the drawings in combination with the embodiments.

[0025] The technical means in the embodiments of the present invention will be described below clearly and completely with reference to the drawings in the embodiments of the present invention, but it is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative labor are all included in the protection scope of the present invention.

[0026] In addition, when there are directional indications (e.g., up, down, left, right, front, back, etc.) in the embodiments of the present invention, the directional indications are only used to interpret the relative positional relationships, movement conditions, etc. between each component in a certain posture (as shown in the drawings), and when the certain posture changes, the directional indications also change accordingly.

[0027] In addition, when there is a description of "first", "second", etc. in the embodiments of the present invention, the description of "first", "second", etc. is used for explanation only, and should not be understood as indicating or suggesting the relative importance or implying the number of technical features shown. Therefore, the features defined by "first", "second", "third" can explicitly or implicitly indicate that at least one of the features is included. In addition, the technical means between each embodiment can be combined with each other, but this combination must be based on what a person skilled in the art can realize. If the combination of technical means is mutually contradictory or cannot be realized, it should be considered that such combination of technical means does not exist and is not within the protection scope required by the present invention.

[0028] 1 and 2, a conventional support leg generally includes a stick 1 and a support leg 2 for supporting the stick 1, one end of the support leg 2 is rotatably connected to the stick 1 or a connection base fitted to the stick 1, and the other end is a free end. When the free end of the support leg 2 is fully extended, the support leg 2 supports the stick 1, and the stick 1 may be connected to a filming device, a mobile phone, an auxiliary light, etc., and therefore the support leg 2 is common in live broadcasting and filming scenes. After use, the free end of the support leg 2 can be retracted to the stick 1 for convenient carrying. As described in the background art, when the conventional support leg needs to be used, the elastic engagement mechanism can be directly pressed to release the restriction on the support leg 2, but the support leg 2 in such a restricted state is not automatically extended, but is only slightly extended from the position in close contact with the stick, and it is necessary to manually rotate the support leg in order to fully extend the support leg 2 and stably support the stick 1.

[0029] In order to solve the above problems, the present invention provides a fully poppable support leg, and referring to FIG. 3, the support leg includes: a stick 1 provided with a connection base 5; a stretchable support leg 2, one end of which is rotatably connected to a connection base 5 and the other end of which is a free end, and when the free end of the support leg 2 approaches the stick 1, the support leg 2 is contracted, and when the free end of the support leg 2 moves away from the stick 1, the support leg 2 is extended; a locking assembly 3 that engages with the free end of the support leg 2 when the support leg 2 is retracted to limit the movement of the support leg 2 relative to the stick 1 and releases the limit after being triggered; The reinforcing rib 4 has one end rotatably connected to the support leg 2 and the other end rotatably connected to the stick 1 or the lock assembly 3, and a first elastic member 42 is provided between the reinforcing rib 4 and the support leg 2, and when the free end of the support leg 2 engages with the lock assembly 3, the first elastic member 42 elastically deforms to generate a restoring force, and when the lock assembly 3 releases the restriction, the restoring force of the first elastic member 42 causes the free end of the support leg 2 to separate from the stick 1 and be fully extended.

[0030] In this embodiment, the tripod being fully extended means that the support leg 2 is extended to a state where it can support or stably support the stick 1; generally, when the tripod is fully extended, the support leg 2 needs to be rotated by a large angle; however, in the prior art, the elastic engagement mechanism only releases the restriction on the support leg 2, and the support leg cannot be automatically extended, and furthermore cannot be automatically fully extended.

[0031] In this embodiment, the triggering manner of the locking assembly 3 may be pressing, rotating or impacting.

[0032] Compared with the prior art, one end of the reinforcing rib 4 of the present invention is rotatably connected to the support leg 2, and the other end is rotatably connected to the stick 1 or the lock assembly 3. A first elastic member 42 is provided between the reinforcing rib 4 and the support leg 2. When the free end of the support leg 2 engages with the lock assembly 3, the first elastic member 42 elastically deforms to generate a restoring force. When the lock assembly 3 releases the restriction, under the action of the restoring force, the free end of the support leg 2 separates from the stick 1 and is fully extended. The ingenious design of the first elastic member 42 solves the problem in the prior art that after the restriction by the lock assembly 3 is released, the support leg 2 is in a slightly extended state and needs to be manually rotated to fully extend the support leg. With the technical means of the present invention, after the restriction by the lock assembly 3 is released, the entire support leg can be fully extended, which is more convenient to use.

[0033] In this embodiment, the number of the support legs 2 of the support leg is three, but is not limited thereto, and may be four, five or other numbers.

[0034] 4 to 6, a first rotating shaft 41 is provided on the reinforcing rib 4, the first rotating shaft 41 is rotatably connected to the support leg 2, and a first elastic member 42 is a torsion spring which is fitted onto the first rotating shaft 41. When the free end of the support leg 2 engages with the lock assembly 3, the torsion spring is twisted to generate a torsion force, and when the lock assembly releases the restriction, the torsion force of the torsion spring causes the free end of the support leg 2 of the support leg to move away from the stick 1 and fully extend.

[0035] The first rotating shaft 41 and the reinforcing rib 4 may be an integral structure, and the first rotating shaft 41 may be rotatably connected to the support leg 2, i.e., the reinforcing rib 4 may be rotatably connected to the support leg 2.

[0036] In this embodiment, at least two first grooves 44 are provided on the support leg 2, and both ends of the first rotating shaft 41 are inserted into the first grooves 44, forming a structure in which the first rotating shaft 41 rotates within the first groove 44, and both ends of the first rotating shaft 41 protrude from the reinforcing rib 4, and the protruding portions of both ends may be inserted into the first grooves 44.

[0037] An easily conceivable equivalent technical means is one in which another removable additional structure is provided on the support leg 2, and the first groove 44 is provided on the removable additional structure, and such technical means should be considered to be equivalent to the first groove 44 being provided directly on the support leg, for example, a position regulating block 43 is provided on the support leg, and the first groove 44 is provided on the position regulating block 43.

[0038] As a preferred technical measure, the support leg 2 is further provided with a position restricting block 43, which is disposed at the opening of the first groove 44 to restrict the first rotating shaft 41 from sliding out of the first groove 44, the first groove 44 being a groove position on the support leg 2, and the position restricting block 43 being detachable from the support leg 2; thus, during the production process, when the first rotating shaft 41 is installed, the first rotating shaft 41 is first inserted into the opening of the first groove 44, and then the position restricting block 43 is connected to the support leg 2 to seal the opening of the first groove 44, thereby restricting the first rotating shaft 41 from sliding out of the first groove 44, which makes the production process more convenient; in this embodiment, the cross section of the first groove 44 is a U-shaped structure, and during installation, the first rotating shaft 41 is inserted into the first groove 44 through the U-shaped opening, and the position restricting block 43 is disposed at the opening of the U-shaped structure.

[0039] As a preferred technical means, the torsion spring includes a main body portion 420, and a first force arm 422 and a second force arm 421 extending from the main body portion 420, the main body portion being fitted onto the first rotating shaft 41, the first force arm 422 abutting against the support leg portion 2, and the second force arm 421 abutting against the reinforcing rib 4.

[0040] In this embodiment, the position restriction block 43 has a first through hole 431, the torsion spring includes a main body 420 and a first force arm 422 and a second force arm 421 extending from the main body 420, the first force arm 422 is restricted in position by passing through or abutting against the first through hole 431, the reinforcing rib 4 has a second through hole, the second force arm 421 is restricted in position by passing through or abutting against the second through hole, and the second force arm 421 is restricted in position by the reinforcing rib 4, when the free end of the support leg 2 engages with the lock assembly 3, the first force arm 422 and the second force arm 421 are twisted to generate a torsional force, and when the lock assembly 3 releases the restriction on the free end of the support leg 2, the torsional force causes the support leg 2 to rotate and fully extend.

[0041] As an easily conceivable equivalent technical means, the first through hole is directly provided in the support leg 2, or no through hole is provided, and the first force arm 422 directly abuts on the position regulating block 43, or the through hole is changed to a groove structure, Such a technical means should be considered to be equivalent to the first through hole 431 being provided in the position restriction block and abutting against the first force arm 422.

[0042] In this embodiment, the reinforcing ribs 4 and the supporting legs 2 are provided in correspondence with each other, and each supporting leg 2 is provided with a corresponding reinforcing rib 4 .

[0043] In this embodiment, the connection base 5 is fitted onto the stick 1, and the connection base 5 can slide relative to the stick 1 when the support leg 2 is retracted or extended.

[0044] 7 to 11, the lock assembly 3 includes a fixed base 32, a trigger button 31, and a second elastic member 34, the fixed base 32 is connected to the stick 1, the second elastic member 34 is provided between the trigger button 31 and the fixed base 32, and an engagement structure is provided at one end of the trigger button 31, and when the support leg 2 is contracted, the engagement structure limits the movement of the support leg 2 relative to the stick 1, i.e., limits the support leg 2 from being extended, and when the trigger button 31 is pressed, the engagement structure moves to release the restriction on the support leg 2.

[0045] In this embodiment, the engagement structure is driven to move by pressing to release the restriction, thereby avoiding the forced separation of the support leg 2 and the stick 1 with a large force, and the structural design is ingenious. The fixed base 32 may be an integral structure with the stick 1, or may be two independent structures connected by adhesive, bolts, or other methods, and the second elastic member 34 may be a spring or a leaf spring.

[0046] In this embodiment, one end of the fixed base 32 is connected to the stick 1, and the other end is provided with a second groove. One end of the second elastic member 34 is accommodated in the second groove and abuts against the bottom of the second groove, and the other end is fitted into the trigger button 31 or abuts against the trigger button 31.

[0047] When the trigger button 31 is pressed, the second elastic member 34 is compressed, causing the trigger button 31 to displace and move the engagement structure, and after the trigger button 31 is released, under the action of the second elastic member 34, the engagement structure is returned to its initial position by the trigger button 31, allowing secondary pressing or collision.

[0048] In this embodiment, in addition to pressing, the support leg can also be directly thrown onto the ground. When the ground hits the trigger button 31, after the trigger button 31 receives the pressure of the ground, it will compress the second elastic member 34 to release the restriction on the free end of the support leg, and then under the action of the torsion spring, it will automatically spring out and fully extend, and the whole process is very convenient.

[0049] In this embodiment, in order to better restrict the second elastic member 34 from being compressed only in the axial direction, a position limiting cover 33 is further provided. The position limiting cover 33 is provided above the groove of the fixed base 32 and forms an accommodating space together with the groove of the fixed base 32. The second elastic member 34 is located within the accommodating space, and the cross-section of the accommodating space is slightly larger than the cross-section of the second elastic member 34, thereby ensuring that the second elastic member 34 is compressed or stretched only along its own axial direction. Preferably, the second elastic member 34 is a spring. In this embodiment, an opening is provided in the position limiting cover 33, and the end of the trigger button 31 that is not fitted with the second elastic member 34 passes through the opening, forming a structure that allows the trigger button 31 to be inserted into the accommodating space.

[0050] A pressing cap is provided on the top of the end of the trigger button 31 where the second elastic member 34 is not fitted, which makes it easier to press.

[0051] In this embodiment, an extension portion 313 is provided at the end of the trigger button 31 that is fitted into the second elastic member 34, the extension portion 313 surrounds the trigger button 31 in the axial direction, and the engagement structure is provided on the extension portion 313. When the trigger button 31 compresses the second elastic member, the engagement structure is driven to move in a direction that compresses the second elastic member 34, and when the engagement structure moves, the restriction on the support leg 2 is released.

[0052] The engagement structure is a first bump 312, and a second bump is provided on the support leg 2, the first bump 312 and the second bump abut against each other to restrict the movement of the support leg 2 relative to the stick 1, when the trigger button 31 is pressed, the first bump 312 moves downward and separates from the second bump to release the restriction on the support leg 2, and after the trigger button 31 is released, the first bump 312 moves upward and returns to the original locked position due to the restoring force of the second elastic member 34. In this embodiment, when the first bump 312 is in the locked position, it passes through the position restriction cover and abuts against the second bump.

[0053] In this embodiment, when the support leg 2 needs to be retracted, it is sufficient to directly rotate the support leg 2 manually and bring it closer to the stick 1. During the retraction process, the second bump 21 on the support leg will first move along the slope of the first bump 312 and press the first bump 312 downward. After the support leg 2 is completely retracted, the first bump 312 will be pushed out again and return to the locking position, abutting against the second bump 21, thereby restricting the extension of the support leg 2.

[0054] Referring to FIG. 12, in this embodiment, in order to assist the support leg 2 to be fully extended, an extrusion block 311 is provided on the side of the end of the trigger button 31 where the second elastic member 34 is not fitted, and when the trigger button 31 is pressed, the engagement structure releases the restriction on the support leg 2, and the extrusion block 311 moves in accordance with the trigger button 31 to push out the support leg 2 so that it moves in the direction of extension, thereby assisting the support leg 2 to be fully extended.

[0055] In this embodiment, the extrusion block 311 is arranged to protrude from the side of the trigger button 31 and has a slope structure, and the slope guides the support leg 2 to move along the slope when the extrusion block 311 moves, and when the extrusion block 311 contacts the support leg 2 and extrudes the support leg 2 from its original position, the contact point with the extrusion block 311 on the support leg 2 becomes the extrusion point, and when the trigger button 31 is not pressed, the extrusion block 311 does not contact the extrusion point, and after the trigger button 31 is pressed, the extrusion point moves against the slope of the extrusion block 311, and the support leg 2 gradually moves away from its original locked position until the extrusion point can no longer extrude the support leg 2.

[0056] In this embodiment, a connection base is provided on the stick 1, one end of the support leg 2 is rotatably connected to the connection base 5, and the other end is a free end, and when the free end of the support leg 2 engages with the lock assembly 3, the support leg 2 is in a contracted state, and when the free end of the support leg 2 is not engaged with the lock assembly 3, the support leg 2 is in an extended or extendable state.

[0057] In this embodiment, one end of the reinforcing rib is rotatably connected to the support leg 2, and the other end is rotatably connected to the fixed base 32 or directly to the stick 1, and the reinforcing rib can greatly improve the stability of the support leg.

[0058] The above is merely a preferred embodiment of the present invention, and does not limit the scope of protection of the present invention. In the concept of the present invention, the equivalent structural transformation made based on the contents of the specification and drawings of the present invention, or the direct / indirect application to other related technical fields are all included in the scope of protection of the present invention.
