The bracket of the surveillance camera head of the embodiment has the following technical effects:
Firstly, by respectively stirring the horizontal locking cam 22 and the vertical locking cam 25 to axially rotate, the horizontal rotating frame 21 or the vertical rotating frame 24 can be respectively fixed or movably rotated, so that maintenance personnel can conveniently rotate and adjust the horizontal direction and the vertical direction, and the maintenance personnel can conveniently and quickly lock the horizontal locking cam 22 and the vertical locking cam 25 without other tools; secondly, when in maintenance, a maintenance person is at a high position, the movable range of the maintenance person is limited, the maintenance person can position and adjust the positions of the horizontal locking cam 22 and the vertical locking cam 25 only by touching, the body does not need to be rotated to the position of the cam, and the safety of the maintenance person is improved; finally, since the horizontal locking cam 22 and the vertical locking cam 25 are provided on the horizontal locking shaft 23 and the vertical locking shaft 26, the cams are not lost during maintenance.
Further, as shown in fig. 3, one end of the horizontal locking shaft 23 is connected to the bottom of the horizontal rotating frame 21; the horizontal locking cam 22 comprises a first cam body 221 connected with the bottom of the horizontal locking shaft 23, two first through holes 222 penetrating through the first cam body 221, a first locking end 223 and a first unlocking end 224 which are arranged on the first cam body 221, wherein the distance between the first locking end 223 and the first through hole 222 is larger than the distance between the first unlocking end 224 and the first through hole 222, when the first cam body 221 rotates to a locking position, the first locking end 223 abuts against the bottom surface of the mounting assembly 1, and when the first cam body 221 rotates to an unlocking position, the first unlocking end 224 abuts against the bottom surface of the mounting assembly 1.
Further, the horizontal locking shaft 23 includes a first shaft body 231 and a first shaft hole 232 disposed at the bottom of the first shaft body 231, and the first shaft body 231 and the first cam body 221 are connected with the first shaft 233 of the first through hole 222 by penetrating the first shaft hole 232.
The horizontal locking cam 22 is connected with the horizontal locking shaft 23 through the first rotating shaft 233, the first cam body 221 rotates by taking the first rotating shaft 233 as an axis, when the first cam body 221 rotates to a locking position, namely, when the first locking end 223 abuts against the bottom surface of the mounting assembly 1, the first rotating shaft 233 pulls the horizontal locking shaft 23 to move towards the mounting assembly 1 due to the fact that the distance between the first locking end 223 and the first rotating shaft 233 is larger than the distance between the first unlocking end 224 and the first rotating shaft 233, and the horizontal rotating frame 21 is driven to be pressed on the mounting assembly 1; when the first cam body 221 rotates to the unlocking position, that is, when the first unlocking end 224 abuts against the bottom surface of the mounting assembly 1, the first rotating shaft 233 no longer forces the horizontal rotating frame 21 to press against the bottom surface of the mounting assembly 1 because the distance between the first unlocking end 224 and the first rotating shaft 233 is smaller than the distance between the first locking end 223 and the first rotating shaft 233, and the horizontal rotating frame 21 can rotate relative to the mounting assembly 1.
Further, the vertical locking cam 25 includes a second cam body 251 connected to an end of the horizontal rotating frame 21, two second through holes 252 penetrating through the second cam body 251, a second locking end 253 and a second unlocking end 254 disposed on the second cam body 251, a distance between the second locking end 253 and the second through hole 252 is greater than a distance between the second unlocking end 254 and the second through hole 252, when the second cam body 251 rotates to the locking position, the second locking end 253 abuts against a side surface of the horizontal rotating frame 21, and when the second cam body 251 rotates to the unlocking position, the second unlocking end 254 abuts against a side surface of the horizontal rotating frame 21.
Further, the vertical locking shaft 26 includes a second shaft body 261 and a second shaft hole 262 disposed at the bottom of the second shaft body 261, and the second shaft body 261 and the second cam body 251 are connected by a second rotating shaft 263 penetrating through the second shaft hole 262 and the second through hole 252.
The vertical locking cam 25 is connected with the vertical locking shaft 26 through a second rotating shaft 263, the second cam body 251 rotates by taking the second rotating shaft 263 as an axis, when the second cam body 251 rotates to a locking position, namely, when the second locking end 253 is propped against the side surface of the horizontal rotating frame 21, the second rotating shaft 263 pulls the vertical locking shaft 26 to move towards the horizontal rotating frame 21 and drives the vertical rotating frame 24 to press the side surface of the horizontal rotating frame 21 because the distance between the second locking end 253 and the second rotating shaft 263 is larger than the distance between the second unlocking end 254 and the second rotating shaft 263; when the second cam body 251 rotates to the unlocking position, that is, when the second unlocking end 254 abuts against the side surface of the horizontal rotating frame 21, the second rotating shaft 263 no longer forces the vertical rotating frame 24 to press against the side surface of the horizontal rotating frame 21 because the distance between the second unlocking end 254 and the shaft is smaller than the distance between the second locking end 253 and the second rotating shaft 263, and the vertical rotating frame 24 can rotate relative to the horizontal rotating frame 21.
Further, the horizontal locking shaft 23 further includes a first limiting cap 234 disposed at a top end of the first shaft body 231, the horizontal rotary frame 21 includes a horizontal rotary frame main body 211, a first disc 212 disposed at a bottom end of the horizontal rotary frame main body 211, and a first opening 213 disposed on the first disc 212, a bottom surface of the first limiting cap 234 abuts against a top surface of the first disc 212, and the first shaft body 231 passes through the first opening 213.
Further, a first elastic member (not shown) is provided between the first stopper cap 234 and the first disk 212. The first elastic member may increase friction between the first stopper cap 234 and the first disk 212 in the locked state.
Further, as shown in fig. 4 and 5, the bottom surface of the first disc 212 is provided with a plurality of first rotating teeth 215 arranged around the circumference of the first opening 213, the mounting assembly 1 includes a bracket arm 11 and a connection part 12 provided at an end of the bracket arm 11 for providing the horizontal rotating frame 21, and the connection part 12 includes a circular groove 121 and two first latch teeth 122 provided at the bottom surface of the circular groove 121 and capable of being snapped in or out between the first rotating teeth 215. When the horizontal locking cam 22 rotates to the locking position, the first rotating shaft 233 pulls the horizontal locking shaft 23 to drive the horizontal rotating frame 21 to move towards the mounting assembly 1, the first clamping teeth 122 are clamped between the two first rotating teeth 215, and the horizontal rotating frame 21 and the mounting assembly 1 are relatively fixed; when the first locking cam rotates to the unlocking position, the first latch 122 is disengaged from between the two first rotating teeth 215, and the horizontal rotating frame 21 can rotate relatively to the mounting assembly 1.
When the locking force in the horizontal direction is provided by the horizontal locking cam 22, that is, when locking is performed only by the static friction force between the horizontal rotating frame 21 and the mounting assembly 1, problems such as slipping easily occur due to factors such as friction during long-term use, and thus locking failure is caused. Therefore, by providing the first rotating teeth 215 and the first latch 122, the locking force in the locked state will be provided by the biting force of the structure, and the locking force of the horizontal locking cam 22 is ensured to keep the first rotating teeth 215 and the first latch 122 meshed, so that the locking force of the horizontal locking cam 22 can be effectively reduced and the service life can be prolonged.
Further, referring to fig. 3 again, the vertical locking shaft 26 further includes a second limiting cap 264 disposed at a top end of the second shaft 261, the vertical rotating frame 24 includes a vertical rotating frame body 241, a second disc 242 disposed at a side end of the vertical rotating frame body 241, and a second opening 243 disposed on the second disc 242, a side surface of the second limiting cap 264, which is close to the vertical rotating frame 24, abuts against a side surface of the second disc 242, which is far from the vertical rotating frame 24, and the second shaft 261 passes through the second opening 243.
Further, a second elastic member 244 is disposed between the second cap 264 and the second disc 242. The second elastic member 244 may increase friction between the second cap 264 and the second disc 242 in the locked state.
Further, referring to fig. 3 and 6, a plurality of second rotating teeth 245 are disposed on a side of the second disc 242 adjacent to the vertical rotating frame 24 and circumferentially arranged around the second opening 243, and two second latches 216 are disposed on a side of the horizontal rotating frame body 211 adjacent to the vertical rotating frame body 241, wherein the second latches 216 can be engaged with or disengaged from the second rotating teeth 245.
Likewise, when the locking force in the vertical direction is provided by the vertical locking cam 25, that is, when locking is performed by only the static friction force between the horizontal rotation frame 21 and the mounting assembly 1, problems such as slipping easily occur due to factors such as friction during long-term use, resulting in locking failure. Therefore, by providing the second rotating teeth 245 and the second latch teeth 216, the locking force in the locked state will be provided by the biting force of the structure, and the locking force of the vertical locking cam 25 can ensure that the second rotating teeth 245 and the second latch teeth 216 remain in engagement, so that the locking force of the vertical locking cam 25 can be effectively reduced while the service life is prolonged.
Further, referring to fig. 5 again, the mounting assembly 1 further includes a fixing portion 13 disposed at an end of the bracket arm 11 away from the connecting portion 12 and configured to be disposed on a fixing plane, and a side surface of the bracket arm 11 is contracted from the fixing portion 13 toward the connecting portion 12. The fixing portion 13 is used for being installed on a fixing plane, the larger the contact surface between the fixing portion and the fixing plane is, the better the fixing effect is, and the connecting portion 12 is used for bearing the surveillance camera head, and the size of the connecting portion is smaller than that of the fixing portion 13, namely, the weight of the connecting portion 12 is reduced, the overweight of the end of the connecting portion 12 is avoided, and the fixing portion 13 is easy to fall off from the fixing plane.
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, and alternatives falling within the spirit and principles of the invention.
