DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Reference Figures 1 to 10 As shown, an embodiment of the present invention provides a fixed mounting bracket for a camera, which is used to fix a camera 300, and includes a first bracket 110, a second bracket 120, and a supporting mechanism. The first bracket 110 is set on a wall, a first ball shell 112 is fixedly set on the first bracket 110, a second ball shell 121 is fixedly set on the second bracket 120, and the camera 300 is set on the second bracket 120.

[0035] The supporting mechanism includes a connecting tube 200, a tightening assembly, two conical blocks 203 and two transmission assemblies. The length direction of the connecting tube 200 is the first direction. The two ends of the connecting tube 200 are respectively fixedly provided with connecting ball heads 202, which are deformable. The two connecting ball heads 202 are respectively rotatably arranged in the first ball shell 112 and the second ball shell 121. Each connecting ball head 202 is provided with a first through groove 130, which is arranged along the second direction, which is perpendicular to the first direction, and the first through groove 130 passes through the connecting ball head 202. A conical groove 2021 is provided in the first through groove 130, which is arranged along the first direction, which is connected to the connecting tube 200, and the radius of the conical groove 2021 gradually decreases along the direction from the two ends of the connecting tube 200 to the middle of the connecting tube 200. Each conical block 203 is slidably arranged in a conical groove 2021. The tapered block 203 and the tapered groove 2021 are arranged in parallel.

[0036] Each transmission assembly includes a rack 211, which is arranged along the first direction and slidably arranged in the connecting tube 200 along the first direction. The two racks 211 are distributed along the circumference of the connecting tube 200, and each rack 211 drives a conical block 203 to move synchronously.

[0037] The tightening assembly includes a screwing shaft 212, which is arranged along the second direction, and is slidably arranged in the connecting tube 200 along the first direction, and the screwing shaft 212 can rotate around its own axis. A gear 2121 is fixedly arranged on the screwing shaft 212, and the gear 2121 is meshed with the two racks 211.

[0038] The first bracket 110 is mounted on the wall, and then the camera 300 is mounted on the connecting base plate 122. At this time, the connecting tube 200 is still in a loose state, and the two connecting ball heads 202 can rotate freely in the first ball shell 112 and the second ball shell 121. Then, the camera 300 is directly swung to the desired position, and the screwing shaft 212 is rotated at the same time. The screwing shaft 212 drives the two racks 211 to approach each other, and each rack 211 drives a conical block 203 to move synchronously. The conical block 203 slides in the conical groove 2021, and the conical block 203 squeezes the connecting ball head 202 outward, so that the connecting ball head 202 is deformed, and the connecting ball head 202 expands outward, and then abuts against the first spherical shell 112 or the second spherical shell 121. The connecting ball head 202 is first pressed against the first spherical shell 112 or the second spherical shell 121, and then the conical block 203 is continued to be moved, so that the connecting ball head 202 and the first spherical shell 112 or the second spherical shell 121 are further locked. After locking, the connecting ball head 202 no longer rotates at will. When the connecting ball head 202 is not pressed tightly against the first ball shell 112 or the second ball shell 121, the connecting tube 200 and the camera 300 can move freely and can be adjusted to a desired position more quickly, and then the connecting tube 200 can be locked, so that the adjustment efficiency is higher.

[0039] When the shaft 212 is turned, the two conical blocks 203 are driven to move synchronously through the two racks 211, and the conical block 203 in the first spherical shell 112 moves to the connecting ball head 202 in the first spherical shell 112 to be deformed, and is pressed against the first spherical shell 112 without further locking. At this time, the movement of the conical block 203 in the second spherical shell 121 makes the connecting ball head 202 in the second spherical shell 121 not deformed, and the connecting ball head 202 in the second spherical shell 121 is not pressed against the second spherical shell 121.

[0040] Then, the screwing shaft 212 is rotated, and the rack 211 corresponding to the first ball shell 112 no longer moves. While the screwing shaft 212 rotates around its own axis, it moves along the first direction toward the first ball shell 112, and at this time, the rack 211 corresponding to the second ball shell 121 continues to drive the conical block 203 to move, until the conical block 203 moves to the connection ball head 202 and deforms to press against the second ball shell 121. When the pressing force of the two conical blocks 203 is consistent, the screwing shaft 212 is then rotated, and the screwing shaft 212 no longer moves, but continues to rotate around itself, 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 connection ball heads 202 and the first ball shell 112 and the second ball shell 121 are locked, so that the locking force at both ends of the connecting tube 200 is consistent, and the fixed mounting bracket for the camera is prevented from loosening due to inconsistent locking force.

[0041] In this embodiment, a first movable groove 201 is provided on the peripheral wall of the connecting tube 200, and the first movable groove 201 is arranged along the first direction. The screwing shaft 212 is slidably arranged in the first movable groove 201 along the first direction, and the two ends of the screwing shaft 212 are a first end and a second end. The first end of the screwing shaft 212 is arranged in the connecting tube 200, and the second end of the screwing shaft 212 is arranged outside the connecting tube 200. The gear 2121 is fixedly arranged at the first end of the screwing shaft 212.

[0042] In this embodiment, two second movable grooves 204 are further provided on the peripheral wall of the connecting pipe 200 . The second movable grooves 204 are arranged along the first direction, and the two second movable grooves 204 are arranged on both sides of the first movable groove 201 .

[0043] A plurality of first protrusions 2126 are fixedly disposed on the peripheral wall of the screwing shaft 212 . The plurality of first protrusions 2126 are distributed along the circumference of the screwing shaft 212 . Each first protrusion 2126 is disposed along the second direction, and there is a gap between two adjacent first protrusions 2126 .

[0044] The support mechanism further includes a locking assembly, which includes a locking block 220. The locking block 220 is provided with a second through slot, which is arranged along the second direction. The second end of the screwing shaft 212 is rotatably arranged in the second through slot, and the locking block 220 can slide up and down relative to the screwing shaft 212. A plurality of second protrusions 222 are fixedly arranged in the second through slot, which are distributed along the circumference of the screwing shaft 212. Each second protrusion 222 is arranged along the second direction, and each second protrusion 222 abuts against a first protrusion 2126. At least two limiting rods 223 are fixedly arranged on the locking block 220, which are arranged along the second direction, and each limiting rod 223 is slidably arranged in a second movable groove 204.

[0045] When both connecting ball heads 202 are locked, the locking block 220 is pushed, and along the second direction, the locking block 220 gradually approaches the connecting pipe 200. The movement of the locking block 220 causes each second protrusion 222 to abut against a first protrusion 2126, and the screwing shaft 212 is locked.

[0046] In this embodiment, a stopper 2122 is fixedly disposed on the peripheral wall of the first end of the screwing shaft 212. The support mechanism further includes a reset assembly, which includes a torsion spring 2123, which is rotatably sleeved on the screwing shaft 212, one end of the torsion spring 2123 is fixedly connected to the stopper 2122, and the other end of the torsion spring 2123 is disposed in one of the second movable grooves 204.

[0047] During the forward rotation of the screw shaft 212, the torsion spring 2123 accumulates force. The second protrusion 222 and the first protrusion 2126 abut against each other, thereby preventing the screw shaft 212 from rotating in the reverse direction and resetting under the action of the torsion spring 2123. At this time, the screw shaft 212 is locked. In addition, under the action of the torsion spring 2123, the first protrusion 2126 and the second protrusion 222 abut against each other, so that the locking block 220 will not fall off and reset.

[0048] In this embodiment, the reset mechanism further includes a spring 221 , which is rotatably sleeved on the twisting shaft 212 , one end of the spring 221 is fixedly connected to the locking block 220 , and the other end of the spring 221 is fixedly connected to the outer wall of the connecting tube 200 .

[0049] When the locking block 220 gradually approaches the connecting pipe 200, the spring 221 is compressed. When the first protrusion 2126 and the second protrusion 222 are pushed due to external reasons, at the moment when the second protrusion 222 crosses over the first protrusion 2126, the second protrusion 222 comes into the gap between two adjacent first protrusions 2126. At this time, the spring 221 is reset and pushes the locking block 220 to reset, so that the first protrusion 2126 and the second protrusion 222 are no longer in contact.

[0050] In this embodiment, a first limiting block 2124 and a second limiting block 2125 are fixedly disposed on the peripheral wall of the twisting shaft 212 . The first limiting block 2124 is located inside the connecting tube 200 , and the second limiting block 2125 is located outside the connecting tube 200 .

[0051] In this embodiment, two T-slots 2111 are provided in the connecting tube 200, and the T-slots 2111 are arranged along the first direction. The two T-slots 2111 are distributed along the circumference of the connecting tube 200. A T-block 205 is fixedly provided on each rack 211, and the T-block 205 is arranged along the first direction, and each T-block 205 is arranged in one T-slot 2111.

[0052] In this embodiment, a turning knob 2127 is fixedly provided on the second end of the turning shaft 212 , and the turning knob 2127 is rotated to drive the turning shaft 212 to rotate synchronously.

[0053] In this embodiment, each transmission assembly further includes a steel wire 2031 , one end of the steel wire 2031 is fixedly connected to the rack 211 , and the other end of the steel wire 2031 is fixedly connected to the tapered block 203 .

[0054] In this embodiment, a connecting base plate 122 is fixedly provided on the second bracket 120 , screws are provided on the connecting base plate 122 , and the camera 300 and the connecting base plate 122 are detachably connected via the screws.

[0055] A working process of a fixed mounting bracket for a camera: the first bracket 110 is mounted on the wall, and then the camera 300 is mounted on the connecting base plate 122. At this time, the connecting tube 200 is still in a loose state, and the two connecting ball heads 202 can rotate freely in the first ball shell 112 and the second ball shell 121. Then the camera 300 is directly swung to the position where it is desired to be placed with one hand, and then the other hand starts to rotate the screw shaft 212. When the screw shaft 212 rotates, it drives the gear 2121 to rotate synchronously. Since the gear 2121 is meshed with the two racks 211, the gear 2121 drives the two racks 211 to approach each other when it rotates. The rack 211 drives the conical block 203 to move through the steel wire 2031, and the two conical blocks 203 approach each other.

[0056] Since the connecting ball head 202 rotates in the first spherical shell 112 and the second spherical shell 121 for a long time, the connecting ball head 202 is easily worn, which causes the radius of the connecting ball head 202 to become smaller.

[0057] When the wear of the connecting ball head 202 is the same, that is, the radius of the connecting ball head 202 is the same and when the distance between the conical block 203 in the first spherical shell 112 and the first spherical shell 112 is the same as the distance between the conical block 203 in the second spherical shell 121 and the second spherical shell 121, the screwing shaft 212 is rotated, and the screwing shaft 212 rotates forward at the original position. When the screwing shaft 212 drives the conical block 203 to move synchronously through the two racks 211, the conical block 203 is in the conical groove 20 21, the conical block 203 presses the connecting ball head 202 outward, so that the connecting ball head 202 is deformed, and the connecting ball head 202 expands outward, and then abuts against the first ball shell 112 or the second ball shell 121. The connecting ball head 202 is first pressed against the first ball shell 112 or the second ball shell 121, and then the conical block 203 is continued to be moved, so that the connecting ball head 202 and the first ball shell 112 or the second ball shell 121 are further locked. After locking, the connecting ball head 202 no longer rotates at will.

[0058] When the wear of the connecting ball head 202 is different, or when the distance between the conical block 203 in the first spherical shell 112 and the first spherical shell 112 is different from the distance between the conical block 203 in the second spherical shell 121 and the second spherical shell 121, when the screwing shaft 212 is rotated forward, the two conical blocks 203 are driven to move synchronously through the two racks 211. When the conical block 203 in the first spherical shell 112 moves to cause the connecting ball head 202 in the first spherical shell 112 to be deformed, and is pressed against the first spherical shell 112 without further locking, at this time, the movement of the conical block 203 in the second spherical shell 121 causes the connecting ball head 202 in the second spherical shell 121 to not be deformed, and the connecting ball head 202 in the second spherical shell 121 is not pressed against the second spherical shell 121.

[0059] Then, when the screwing shaft 212 is rotated forward, the rack 211 corresponding to the first ball shell 112 no longer moves, and the screwing shaft 212 rotates around its own axis while moving along the first direction toward the first ball shell 112. At this time, the rack 211 corresponding to the second ball shell 121 continues to drive the conical block 203 to move until the conical block 203 moves to the connection ball head 202 and is deformed and pressed against the second ball shell 121.

[0060] When the tightening force of the two conical blocks 203 is consistent, the screwing shaft 212 is then rotated forward, and the screwing shaft 212 no longer moves but continues to rotate around itself. 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 ball heads 202 and the first ball shell 112 and the second ball shell 121 to be locked, so that the locking force at both ends of the connecting tube 200 is kept consistent, preventing the connecting tube 200 from loosening due to inconsistent locking force.

[0061] During the forward rotation of the screwing shaft 212, the torsion spring 2123 accumulates force. Then, the locking block 220 is pushed, and along the second direction, the locking block 220 gradually approaches the connecting pipe 200, and the spring 221 is compressed. The movement of the locking block 220 causes each second protrusion 222 to abut against a first protrusion 2126, thereby preventing the screwing shaft 212 from rotating in the reverse direction and resetting under the action of the torsion spring 2123. At this time, the screwing shaft 212 is locked. And under the action of the torsion spring 2123, the first protrusion 2126 and the second protrusion 222 abut against each other, so that the locking block 220 will not fall off and reset.

[0062] When the fixed mounting bracket for the camera is hit due to human reasons or other factors, the cooperation between the first protrusion 2126 and the second protrusion 222 will be pushed. At the moment when the second protrusion 222 crosses the first protrusion 2126, the second protrusion 222 comes into the gap between the two adjacent first protrusions 2126. At this time, the spring 221 is reset and pushes the locking block 220 to reset, so that the first protrusion 2126 and the second protrusion 222 are no longer in contact. At the same time, the torsion spring 2123 is reset, driving the screwing shaft 212 to rotate in the opposite direction. When the screwing shaft 212 rotates in the opposite direction, it drives the two racks 211 away from each other, and then drives the two conical blocks 203 away from each other, and the connecting ball head 202 is deformed and reset, and the connecting ball head 202 shrinks inward, so that the connecting ball head 202 and the first ball shell 112 or the second ball shell 121 are out of contact. At this time, the connecting tube 200 is no longer locked, and the connecting tube 200 can rotate freely, preventing a fixed mounting bracket for the camera from breaking and causing harm to personnel.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
