Description

Technical Field

[0001] The utility model relates to the field of photographic accessories, in particular to a novel anti-reversal positioning adapter. Background Art

[0002] In the field of photography, the shooting angle has a great impact on the quality of the product. A slight deviation will greatly change the photographic effect. In addition, the photography environment is complex and changeable, and loose connections often occur, and the occasional shaking of the photographic equipment also affects the photographic product effect. More seriously, due to loose connections, the photographic equipment may become loose and damaged.

[0003] The Chinese utility model discloses a photographic adapter accessory that can be reinforced and prevented from loosening (authorization announcement number CN217682740U). This photographic adapter accessory uses a turntable to reinforce the connection between the camera screw and the photographic instrument, effectively reducing the loose connection. Furthermore, the camera screw and the two adapter clamps are not connected in an integrated manner. During the process of reinforcing the connection between the camera screw and the photographic instrument, the deflection of the two adapter clamps can be adjusted. However, the turntable rotation in this technical solution cannot be operated continuously, and it is necessary to continuously switch the operation between the four reinforcement holes. Summary of the invention

[0004] The purpose of the utility model is to provide a new anti-reversal positioning adapter to solve the problems raised in the above background technology and to solve the reversal and positioning deviation problems by adopting a new and simple structural solution.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of anti-reversal positioning adapter, including an adapter foot, a connecting rod, a seal and a support seat, the adapter foot is fixedly connected to the support seat, and is characterized in that: the connecting rod is composed of a threaded rod and a head structure; the top of the support seat is provided with an inner groove for nesting the connecting rod, and the bottom is provided with a through hole connected to the inner groove, and the position of the through hole corresponds to the wrench groove of the connecting rod head structure nested in the inner groove; the seal is fixed to the support seat after passing through the connecting rod; the adapter foot reserves space for a wrench to extend from the bottom to adjust the connecting rod.

[0006] Preferably, the transfer pins are two parallel pins, and symmetrical through holes are respectively provided at one end of the transfer pin away from the support seat, and thinning cuts are respectively provided at the other end of the transfer pin close to the support seat.

[0007] Preferably, the transfer pin is a parallel tripod, one of the side pins at one end of the transfer pin away from the support seat is provided with a screw hole, and the other side pin and the middle pin are provided with through holes.

[0008] Preferably, the inner sinking tank has a built-in limiter for limiting the displacement of the connecting rod.

[0009] With this structure, since the connecting rod is connected to the support base in a nested manner, rather than being connected as a whole, the loosening problem of the photographic instrument caused by external forces is effectively reduced. Furthermore, the wrench can directly and continuously rotate the connecting rod from the reserved space of the transfer pin, and during the rotation process, the deflection of the support base can be adjusted. The transfer pin is a parallel pair of pins or three pins, which can be adapted to a variety of transfer equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION Embodiment 1:

[0020] See also Figure 1-48. The utility model provides a novel anti-reversal positioning adapter, comprising an adapter foot, a connecting rod, a sealing member and a support seat 1, wherein the adapter foot is integrally connected to the support seat 1, the connecting rod is a bolt 2 composed of a screw rod 2-3 and a bolt head 2-2, a wrench groove 2-1 is provided on the top of the bolt head 2-2, an inner recessed groove 1-1 for nesting the bolt is provided on the top of the support seat 1, a through hole 1-3 connected to the inner recessed groove is provided on the bottom, the position of the through hole 1-3 corresponds to the wrench groove 2-1 of the bolt head 2-2 nested in the inner recessed groove, and the wrench groove 2-1 is a countersunk hexagonal socket; the sealing member is a plastic pad 4, a through hole is provided in the middle, the bolt 2 passes through the through hole, and the plastic pad 4 is fixed in the rubber pad groove 1-2 on the top of the support seat by glue, the plastic pad 4 can both limit the displacement of the bolt and have a buffering function to protect the photographic instrument; the inner recessed groove 1-1 has a built-in limiter, the limiter is a plastic cylinder 3, and the plastic cylinder 3 is used to limit the displacement of the bolt.

[0021] The transfer pins are two parallel cards 1-4, and the two cards 1-4 are provided with symmetrical first through holes 1-4-1 at one end away from the support seat, and thinning cuts 1-4-2 at one end close to the support seat. Space is reserved between the two cards for a wrench to extend into the adjustment bolt from the bottom.

[0022] Connect the camera with screw holes to the bolts, and use a hexagonal wrench to insert from the bottom of the two clamps to strengthen the connection between the camera and the bolts. During the reinforcement process, if the support seat is tilted, it can be straightened and fixed in time. After that, use the matching bolts and nuts to pass through the through holes of the two clamps to connect to other equipment. Embodiment 2:

[0023] See also Figure 5-7 The adapter pin is a parallel three-card clamp 5, one side of the three-card clamp 5 away from the support seat is provided with a screw hole 5-2, and the other side and the middle foot are provided with a second through hole 5-1. A space is reserved in the middle of the three-card clamp for a wrench to extend from the bottom to adjust the bolt. Because one side of the three-card clamp has its own thread, the three-card clamp can be connected to other equipment with just a bolt.

[0024] In the present invention, the fixed connection between the transfer foot and the support seat can also adopt other connection methods, such as threaded connection and bushing connection. In addition, the limiter can also adopt irregular metal parts or objects of other materials, as long as they are built into the inner sink and prevent the bolt from moving.
