In this embodiment, the second bracket 120 is fixedly provided with a connection base plate 122, the connection base plate 122 is provided with a screw, and the camera 300 and the connection base plate 122 are detachably connected through the screw.
The working process of the fixed mounting bracket for the camera comprises the following steps: the first bracket 110 is mounted on the wall surface, and then the camera 300 is mounted on the connection base plate 122. At this time, the connection pipe 200 is still in a loose state, and the two connection balls 202 can freely rotate in the first ball housing 112 and the second ball housing 121. Then, the camera 300 is directly swung to a desired position by holding the camera by hand, and then the other hand starts to rotate the screwing shaft 212, and when the screwing shaft 212 rotates, the gear 2121 is driven to synchronously rotate, and when the gear 2121 is meshed with the two racks 211, the gear 2121 drives the two racks 211 to mutually approach. The rack 211 drives the tapered blocks 203 to move through the steel wire 2031, and the two tapered blocks 203 approach each other.
Since the connection ball 202 rotates within the first and second ball cases 112 and 121 for a long time, the connection ball 202 is easily worn, resulting in a smaller radius of the connection ball 202.
When the wear of the connecting ball 202 is the same, that is, the radius of the connecting ball 202 is the same, and when the distance between the conical block 203 in the first ball shell 112 and the distance between the conical block 203 in the second ball shell 121 and the second ball shell 121 is the same, the screwing shaft 212 rotates in the normal direction at the original position, the screwing shaft 212 drives the conical block 203 to synchronously move through the two racks 211, the conical block 203 slides in the conical groove 2021, the conical block 203 presses the connecting ball 202 outwards, so that the connecting ball 202 deforms, the connecting ball 202 expands outwards, and then abuts against the first ball shell 112 or the second ball shell 121, the connecting ball 202 abuts against the first ball shell 112 or the second ball shell 121, and then the conical block 203 continues to move, so that the connecting ball 202 and the first ball shell 112 or the second ball shell 121 are further locked, and the connecting ball 202 does not rotate randomly after locking.
When the wear of the connecting ball 202 is different, or when the distance between the conical block 203 in the first ball shell 112 and the first ball shell 112 is different from the distance between the conical block 203 in the second ball shell 121 and the second ball shell 121, the screwing shaft 212 is rotated forward, and the two conical blocks 203 are driven to move synchronously by the two racks 211, when the conical block 203 in the first ball shell 112 moves to deform the connecting ball 202 in the first ball shell 112 and is propped against the first ball shell 112 without further locking, the movement of the conical block 203 in the second ball shell 121 causes the connecting ball 202 in the second ball shell 121 to not deform, and the connecting ball 202 in the second ball shell 121 is not propped against the second ball shell 121.
When the screwing shaft 212 is rotated in the forward direction, the rack 211 corresponding to the first spherical shell 112 does not move any more, the screwing shaft 212 rotates around the axis of the screwing shaft, and moves along the first direction towards the direction close to the first spherical shell 112, and at the moment, the rack 211 corresponding to the second spherical shell 121 continues to drive the conical block 203 to move until the conical block 203 moves until the connecting ball 202 deforms to be tightly propped against the second spherical shell 121.
When the tightening force of the two conical blocks 203 is consistent, the screwing shaft 212 is rotated forward, the screwing shaft 212 does not move any more and continues to rotate around the screwing shaft 212, and the screwing shaft 212 continues to drive the two racks 211 to move, so that the two conical blocks 203 continue to move to the two connecting balls 202 and the first spherical shell 112 and the second spherical shell 121 to be locked, the locking forces at the two ends of the connecting pipe 200 are kept consistent, and the connecting pipe 200 is prevented from loosening when the locking forces are inconsistent.
During the forward rotation of the screw shaft 212, the torsion spring 2123 stores the force. Thereafter, the locking block 220 is pushed, and in the second direction, the locking block 220 gradually approaches the connection pipe 200, and the spring 221 is compressed. The movement of the locking block 220 causes each of the second protrusions 222 to abut against one of the first protrusions 2126, thereby preventing the twisting shaft 212 from being reversely rotated to return under the action of the torsion spring 2123, and at this time the twisting shaft 212 is locked. And under the action of the torsion spring 2123, the first bump 2126 and the second bump 222 are abutted against each other, so that the locking block 220 cannot fall off and reset.
When the fixed mounting bracket for the camera is impacted due to human factors or other factors, the first bump 2126 and the second bump 222 are pushed, the second bump 222 comes into a gap between two adjacent first bumps 2126 at the moment when the second bump 222 crosses the first bump 2126, at this time, the spring 221 is reset, and pushes the locking block 220 to reset, so that the first bump 2126 and the second bump 222 are not contacted any more, and at the same time, the torsion spring 2123 is reset, the screwing shaft 212 is driven to reversely rotate, the screwing shaft 212 drives the two racks 211 to be away from each other when reversely rotating, the two conical blocks 203 are driven to be away from each other, the connecting ball 202 is deformed and reset, the connecting ball 202 is retracted inwards, and then the connecting ball 202 and the first ball 112 or the second ball 121 are separated from contact, at this time, the connecting pipe 200 is not locked, and the connecting pipe 200 can freely rotate, so that the fixed mounting bracket for the camera is prevented from being broken, and injury is caused to personnel.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
