Description

Technical Field

[0001] The utility model relates to the field of photographic equipment, in particular to a photographic base which is easy to flip. Background Art

[0002] Cameras, camcorders, mobile phones, etc. are used as shooting equipment. In order to make the shooting effect more perfect, they will be equipped with a lot of photographic equipment, such as tripods, hanging rail mobile brackets, etc. When installing the shooting equipment on these photographic equipment, a photographic base is needed. When using, fix the shooting equipment on the photographic base, and then fix the bottom of the photographic base on the photographic equipment. The purpose is to save money and facilitate installation. When different photographic equipment needs to be replaced, just remove the photographic base from the photographic equipment and then install it on another photographic equipment, so that one photographic base can be used with multiple photographic equipment. However, when using a single photographic equipment, different angles are often used for shooting, such as horizontal shooting, vertical shooting, etc. At present, in order to facilitate users to adjust the angle of the shooting equipment, it is generally chosen to set a direction adjustment ball head on the photographic base, and the direction adjustment ball head is used to control the direction of the shooting equipment. However, there is a problem with the direction-adjusting ball head, that is, it controls the direction of the shooting device through the friction between the ball head and the photographic base. This results in that when the photographer applies a large force to the shooting device, the ball head will overcome the friction and cause deflection. Therefore, many photographers have reported that the ball-head type photographic base will slip as soon as it touches the shooting device. Utility Model Content

[0032] Reference Figures 1 to 6 , a photographic base that is easy to flip, comprising:

[0033] A bottom plate 10, wherein a mounting position 11 is disposed on the bottom plate 10, a pivoting platform 12 is disposed on the base, a mounting cavity 13 is disposed at the front end of the pivoting platform 12, and a limiting structure is disposed in the mounting cavity 13;

[0034] A fixing seat 20, the fixing seat 20 is located above the bottom plate 10, a fixing position 21 is provided on the surface of the fixing seat 20, a front connecting body 23 and a rear connecting body 22 are provided on the fixing seat 20, the rear connecting body 22 is pivotally connected to the rear end of the pivoting platform 12 through a first pivot axis, and an axis hole 231 is provided on the front connecting body 23;

[0035] A movable locking column 30, wherein the movable locking column 30 is inserted into the installation cavity 13 and cooperates with the limiting structure, wherein the limiting structure restricts the movable locking column 30 to move forward and backward in the installation cavity 13, and a bolt hole 31 coaxial with the first pivot axis is provided on the front end surface of the movable locking column 30;

[0036] A locking assembly, the locking assembly comprising a first clamping member and a plurality of second clamping members meshing with each other, the second clamping members being arranged in a ring shape with the bolt hole 31 as the center, the first clamping member and the second clamping member being respectively arranged on the front end surface of the movable locking column 30 and the rear end surface of the front connecting body 23;

[0037] The adjusting handle 40 has a rod body disposed inside the adjusting handle 40 . The inner side of the adjusting handle 40 is used to abut against the outer surface of the front connecting body 23 . An external thread 401 is disposed at the end of the rod body. The rod body passes through the shaft hole 231 and is screwed into the bolt hole 31 .

[0038] The mounting position 11 on the base is used to fix with photographic equipment, and the fixing position 21 is used to install the shooting equipment. Under normal circumstances, the adjusting handle 40 is rotated to make the external thread 401 at the end of the rod body screw into the bolt hole 31 on the front end face of the movable locking column 30. Since the movable locking column 30 is restricted by the limiting structure and can only move back and forth in the mounting cavity 13 but cannot rotate, the movable locking column 30 will be pulled out toward the outside of the mounting cavity 13 during the rotation of the adjusting handle 40, and the first clamping member and the second clamping member are respectively arranged on the front end face of the movable locking column 30 and the rear end face of the front connecting body 23, so that After the bottom surface of the adjusting handle 40 is attached to the outer side of the front connecting body 23 and the movable locking column 30 is pulled outward to a certain extent, the first clamping part will engage with the second clamping part. At this time, the fixed seat 20 cannot be flipped relative to the base plate 10. When the angle of the fixed seat 20 needs to be adjusted, the adjusting handle 40 drives the rod body to rotate, thereby driving the movable locking column 30 to move toward the inside of the installation cavity 13, thereby releasing the engagement between the first clamping part and the second clamping part, so that the fixed seat 20 can swing freely. By engaging the first clamping part with the corresponding second clamping part, the orientation angle of the fixed seat 20 can be conveniently adjusted.

[0039] For further optimization, it is preferred that the first clamping member is a clamping pin 232 arranged on the rear end face of the front connecting body 23, and the clamping pin 232 is inserted into the installation cavity 13, and the second clamping member is a positioning notch 32 arranged on the front end face of the movable locking column 30. Of course, it can also be set in reverse.

[0040] On this basis, preferably all the positioning notches 32 are evenly arranged in a circular array on the front end surface of the movable locking cylinder 30 , so that when the latch 232 is engaged with each positioning notch 32 , the rotation angle of the fixing seat 20 is the same.

[0041] For further optimization, it is preferred that the number of the bayonet pins 232 is the same as the number of the positioning notches 32, and all the bayonet pins 232 are evenly arranged on the rear end face of the front connector 23 in a circular array with the axial hole 231 as the center. Through this structure, when the connection is made, a bayonet pin 232 is inserted into each positioning notch 32, so that the force balance between the bayonet pins 232 and the positioning notches 32 can be maintained, the strength is higher, and it is less prone to fatigue, thereby extending the service life.

[0042] For further optimization, it is preferred that a plurality of protruding teeth 33 are provided in a ring shape on the front end surface of the movable locking cylinder 30 , and the positioning notch 32 is formed between two adjacent protruding teeth 33 .

[0043] In other embodiments, the first clamping member may be a plurality of first clamping teeth protruding from the front end surface of the movable locking column 30, all the first clamping teeth are connected end to end to form a first annular rack, the rear end surface of the front connecting body 23 is provided with an annular groove, the second clamping member may be a plurality of second clamping teeth arranged in the annular groove, all the second clamping teeth are connected end to end to form a second annular rack, and the first annular rack and the second annular rack are meshed with each other.

[0044] For further optimization, it is preferred that an elastic member connected to the movable lock column 30 is also provided in the installation cavity 13, and the elastic member gives the movable lock column 30 a force to move toward the outside of the installation cavity 13. At this time, the rod body needs to be able to move freely forward and backward along the shaft hole 231. Through this structure, in the process of rotating the adjustment handle 40 to move the movable lock column 30 along the rod body toward the inside of the installation cavity 13, the user also needs to press the adjustment handle 40 by hand against the outside of the front connecting body 23, and then the first clamping member can be smoothly separated from the second clamping member, so that the fixed seat 20 and the bottom plate 10 can be smoothly flipped and adjusted. When the user lets go, the elastic member will drive the movable lock column 30 and the adjustment handle 40 to move toward the outside of the installation cavity 13, so that the first clamping member and the second clamping member are engaged under the action of the elastic member, and at this time the adjustment handle 40 will drive the rod body to be partially exposed outside the front connecting member. This design is to avoid the problem that the user accidentally turns the adjustment handle 40, thereby causing the fixed seat 20 to rotate.

[0045] In this solution, the inner end of the movable lock column 30 is preferably provided with an auxiliary hole 301 , and the elastic member is a compression spring 50 inserted in the auxiliary hole 301 . By providing the auxiliary hole 301 at the inner end of the movable lock column 30 , space can be saved.

[0046] In other implementations, the elastic member may also be an elastic column, two mutually repelling magnets, etc.

[0047] For further optimization, in order to facilitate assembly, the front connector 23 is preferably screwed to the fixed seat 20. In this way, the front connector 23, the adjustment handle 40 and the movable lock column 30 are first installed, and then the rear connector 22 on the fixed seat 20 is pivotally connected to the base plate 10. After that, the movable lock column 30 is installed as a whole into the installation cavity 13, and the front connector 23 is screwed to the fixed seat 20, so that the installation is more convenient.

[0048] If the front connector 23 and the rear connector 22 are integrally formed on the fixing seat 20, then either the first clip or the second clip needs to be set on the rear end face of the front connector 23, and the first clip or the second clip cannot protrude from the rear end face of the front connector 23, or additional accessories are needed to adjust the position and fix it, which is more troublesome.

[0049] In the present embodiment, the rod body preferably includes a front smooth rod section 41 and a rear connecting section, the external thread 401 is arranged on the connecting section, and a limiting ring 42 for abutting and limiting the position of the movable locking column 30 is arranged between the connecting section and the smooth rod section 41. The purpose of the limiting ring 42 is to limit the position of the movable locking column 30, that is, the movable locking column 30 can only move on the rod body to abut against the surface of the limiting ring 42 at most.

[0050] In this embodiment, the limiting structure is preferably a limiting cavity 14 arranged on the bottom surface of the installation cavity 13, the cross-section of the movable lock column 30 is non-circular, and the movable lock column 30 is inserted in the limiting cavity 14, so that the rotation of the movable lock column 30 is limited by the shape of the limiting cavity 14.

[0051] In other embodiments, two limiting through holes running through the front and back may be provided on the movable lock column 30 , and two pins inserted into the limiting through holes may be provided in the installation cavity 13 , thereby limiting the rotation of the movable lock column 30 .

[0052] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
