Description

Technical Field

[0001] The invention relates to the field of monitoring technology, in particular to a camera support component and a camera thereof. Background Art

[0002] A camera is a device that can capture images and videos. It is widely used in security, transportation, electronics, industry and other fields. In the security field, cameras can be used for real-time monitoring, crime prevention, providing evidence for incident investigations, and improving the overall level of security management, providing strong protection for people's lives and property safety. In order to provide better and stronger protection for people, it is necessary to improve the optimization of the camera's own hardware to ensure high-definition images. At the same time, the camera's field of view is also crucial. A large field of view can present more key information and provide more event clues, thereby effectively protecting people's lives and property safety.

[0003] In order to obtain a wider field of view, a solution is provided in the prior art. For example, patent application number CN202120515131.9 provides a smart adjustable surveillance camera. The patent provides a solution including a wall, a mounting bracket is provided on one side of the wall, baffles are symmetrically provided on both sides of the mounting bracket, a card slot is provided inside the mounting bracket, a clamp is provided inside the card slot, one end of a connecting rod is provided at the bottom of the clamp, a bearing is provided at the other end of the connecting rod, a connecting sleeve is provided on the outside of the outer shaft of the bearing, a first gear is provided on the top of the connecting sleeve, and a second gear is provided on the top of the first gear. The rotation of the electric motor drives the second gear to rotate, thereby causing the first gear to rotate, and then realizing the rotation of the connecting sleeve and the camera fixedly installed at the bottom thereof, so as to realize the rotation of the camera, which is convenient for observing a wider field of view. The direction of the camera can be changed by only controlling the rotation angle of the electric motor, which increases the intelligence of the camera. The longer card mounting bracket and the longer card slot provide a larger space for the installation of the fixture. However, when the mounting bracket faces a curved surface or a pipe-like arc surface, it is necessary to replace other matching bases or weld a mounting seat flush with the base on the arc surface for installation. During installation, the curvature of the mounting surface is different in size, and matching bases must be produced for mounting surfaces with different curvatures, which increases the production cost of the equipment. In addition, welding a mounting seat flush with the base on the arc surface for installation will damage the mounting surface and make the installation complicated. Summary of the invention

[0004] The object of the present invention is to provide a camera support assembly and a camera thereof, so as to solve the problem that during camera installation, a mounting bracket cannot be simultaneously adapted to arc surfaces and planes with different curvatures for installation.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A camera support assembly comprises a base plate, a chain, a chain link and a matching part, wherein chains are hinged on both sides of the base plate, the chain is composed of a plurality of hinged chain links, the chain link at one end of the chain away from the base plate is connected to the matching part, a through groove is provided on the matching part, the through groove is used to install bolts, a pre-tightening assembly is provided on the chain, and the pre-tightening assembly stretches or extrudes the chain through the extrusion of the bolts.

[0007] It is easy to understand that the base plate is hinged to the chain, and the chain is composed of a pair of hinged links. Due to the rotational connection between the links, the chain as a whole has a certain degree of flexibility. The rotation angle between the connections is adjusted to adapt to different installation surfaces. When the links are in a parallel state, the chain as a whole is in a horizontal state. This state is suitable for the case where the installation surface is a plane. When the installation surface is an arc surface, the chain is in a bent state and wrapped around the arc surface by adjusting the angle between the links. After matching the installation surface, the mating parts connecting the two ends of the chain are fixed by bolts. At the same time, the preload assembly uses the extrusion of the bolts to stretch or extrude the chain.

[0008] The lock member is a pair of locks, each of which has a first end connected to the second end of the guide rail and a second end connected to the second guide rail, the second end of the lock member being connected to the second guide rail and a third end of the lock member.

[0009] After the chain is installed on the surface of the wall facility, the chain is fixed. Since there is a gap between the connection between the chain link, the swivel seat and the pre-tightening component, the gap will cause the camera to vibrate when affected by the external environment, resulting in blurred camera images and shortening the service life of the camera. Therefore, pre-tightening components are connected to both ends of the chain. The bolts pass through the fixing part on the locking block and connect to the wall, and slide it into the through groove. When the surface of the wall facility to be installed is an arc surface, align the driving part of the locking block with the No. 1 guide groove. During the process of tightening the bolt, the bolt pushes the locking block to slide downward in the through groove. During the process, the driving part cooperates with the No. 1 guide groove. Since the driving part and the No. 1 guide groove are both V-shaped, under the action of the side walls of the two, the guide block is driven to slide in the matching part, pulling the connecting block, thereby driving the chain and tightening the chain, so that the contact between the chain link, the swivel seat and the pre-tightening component is closer. Thereby, the gaps between the chain links are eliminated. When the surface of the wall facility to be installed is flat, the driving part of the locking block is aligned with the No. 2 guide groove. As the bolt is tightened, the bolt pushes the locking block to slide downward in the through groove. During the process, the driving part cooperates with the No. 2 guide groove. Since the driving part and the No. 2 guide groove are both V-shaped, under the action of the side walls of both, the guide block is driven to slide in the matching part, push the connecting block, and squeeze the chain, so that the contact between the chain links, the swivel seat and the pre-tightening assembly is tighter, thereby eliminating the gaps between the chain links. The cooperation of the locking block with the No. 1 guide groove and the No. 2 guide groove is used to make the contact between the chain links, the swivel seat and the pre-tightening assembly on the curved surface or plane more closely, thereby eliminating the gaps between the chain links, avoiding the problem that the camera will vibrate when affected by the external environment due to the existence of the gap, resulting in blurred camera images and shortened service life, thereby improving the service life of the camera and the clarity of the image.

[0010] Preferably, the chain link includes a supporting part and a hinge part, one side of the supporting part is connected to the hinge part, and a hinge groove is opened at the lower end of the other side of the supporting part, the hinge groove is hinged to the hinge part on the adjacent chain link, the hinge groove is fitted with the upper end surface of the adjacent hinge part, and No. 1 wedge blocks are provided on both sides of the hinge groove, the No. 1 wedge blocks are made of elastic material, and the No. 1 wedge blocks are interference fit with the side of the hinge part.

[0011] During the use of the camera, due to the longitudinal gap when the chain links are connected, the chain will bend due to the weight of the camera itself, which will cause the angle of the camera to shift. At the same time, the gap will cause the camera to vibrate when affected by the external environment, resulting in blurred camera images and shortening the service life of the camera. Therefore, the hinge groove and the upper end surface of the hinge are designed to fit together, and a No. 1 wedge block is provided on both sides of the hinge groove, and the side edge of the hinge portion of the No. 1 wedge block has an interference fit. The hinge groove fits the upper end surface of the hinge portion on the adjacent chain links to limit the rotation angle and prevent the chain from lifting. At the same time, the No. 1 wedge block has an interference fit with the side edge of the hinge portion to eliminate the longitudinal gap when the chain links are connected, avoid the chain from bending, which causes the angle of the camera to shift. At the same time, the gap will cause the camera to vibrate when affected by the external environment, causing blurred camera images and shortening the service life of the camera. The service life of the camera and the clarity of the image are improved.

[0012] Preferably, a No. 1 limiting block is provided on the upper end surfaces at both ends of the support part, and a plurality of arc-shaped No. 1 matching grooves are provided on the inner side wall of the No. 1 limiting block, and the plurality of No. 1 matching grooves are distributed in an axial array along the direction of the connecting block, and a No. 2 matching groove is provided on the upper end surfaces at both ends of the support part, and a support sheet is provided in the No. 2 matching groove, and a matching block is provided on the side wall of the support sheet, and a No. 2 wedge block is provided on the outer side wall of the support sheet, and the No. 2 wedge block is located below the matching block, and the lower end surface of the No. 2 wedge block coincides with the lower end surface of the support sheet, the thickness of the No. 2 wedge block is greater than the thickness of the matching block, the No. 1 limiting block cooperates with the No. 2 matching groove, and the matching block is slidably connected with the No. 1 matching groove.

[0013] When installing the camera on the curved surface, the locking block is matched with the No. 1 guide groove through bolts, and the chain link is stretched through the connecting block. During the matching process, stress is generated between the chain links, and the stress is transmitted to the bolt through the chain. The stress causes the axial position of the bolt to shift. The shift of the bolt position will change the position between the chain links, and then a gap will be generated. The existence of the gap will cause the camera to vibrate when affected by the external environment, resulting in blurred camera images and shortening the service life of the camera. Therefore, a No. 1 limiting block and a No. 2 matching groove are provided at both ends of the chain link, a support sheet is provided in the No. 2 matching groove, and a matching block is provided on the side wall of the support sheet. There are multiple No. 1 matching grooves on the block. When the locking block cooperates with the No. 1 guide groove and the chain is pulled through the connecting block, the chain links on the chain are pulled. At this time, the chain links are tightly fitted together. In this process, the matching block comes to the corresponding No. 1 matching groove as the chain link moves and cooperates with it. By utilizing the matching of the matching block with the corresponding No. 1 matching groove when the chain link is stretched, the stress between the chain links is transferred to the matching block, avoiding the tensile stress between the chain links from being transmitted to the bolts, resulting in gaps between the chain links due to the offset of the bolt position, causing blurred camera images and shortening the service life of the camera. The service life of the camera and the clarity of the image are improved.

[0014] Furthermore, when the camera is installed on a flat surface, the No. 1 limiting block cooperates with the No. 2 matching groove, and the No. 1 limiting block squeezes the No. 2 wedge block to bend the supporting plate, thereby driving the matching block to separate from the No. 1 matching groove. The No. 2 wedge block is squeezed by the No. 1 limiting block to separate the matching block from the No. 1 matching groove, thereby preventing the matching block from hindering the mutual squeezing of the chain links, thereby ensuring the normal installation of the camera on the flat surface.

[0015] Preferably, the No. 1 wedge block is made of elastic material, a No. 1 card slot is provided on the side of the support portion, the No. 1 wedge block includes a sliding portion and an extrusion portion, the sliding portion is arranged inclined, and the No. 1 card slot is located on the vertical projection surface of the sliding portion.

[0016] The camera is affected by external factors, such as vibrations caused by wall facilities, speeding cars and wind, as well as the temperature difference between day and night, which will cause the side fitting of the hinge part and the hinge groove to loosen and shift in position, resulting in a gap between the No. 1 wedge block and the side of the hinge part. Therefore, the No. 1 wedge block is made of rubber, which has high elasticity, good flexibility, wear resistance and corrosion resistance, and can play a role in vibration reduction. At the same time, through the No. 1 card slot opened on the support part, when the hinge part cooperates with the No. 1 wedge block, the extrusion part is squeezed by the hinge part to deform it and expand toward the sliding part. At this time, the volume of the sliding part increases and is embedded in the No. 1 card slot to limit the position of the hinge part. By setting the material of the No. 1 wedge block and limiting the position of the hinge part through the No. 1 card slot, vibration and position shift between the hinge part and the hinge groove are avoided, ensuring the close fit between the No. 1 wedge block and the hinge part.

[0017] Preferably, a No. 2 card slot is horizontally opened on the inner side wall of the through slot, the driving part includes a matching layer, a deformation layer and an extrusion layer, the lower end surface of the matching layer is V-shaped and matches with the No. 1 guide groove and the No. 2 guide groove, the deformation layer is located between the matching layer and the extrusion layer, the No. 2 card slot is located within the height range of the deformation layer, and the deformation layer is made of elastic material.

[0018] The camera is affected by external factors, such as vibrations generated by wall facilities, speeding cars and wind. The vibrations are transmitted to the lock block and the bolts, which will cause the bolts to loosen and the drive part on the lock block to separate from the No. 1 guide groove and the No. 2 guide groove, thereby generating a gap. The existence of the gap will cause the camera to vibrate when affected by the external environment, resulting in blurred camera images. Therefore, a No. 2 card slot is opened on the inner wall of the through slot to make the No. 2 card slot fit with the deformation layer on the lock block. When the bolt fixes the lock block, the bolt is turned. When the matching layer matches with the No. 1 guide groove and the No. 2 guide groove, as the bolt is continuously tightened, the deformation layer is squeezed under the action of the matching layer and the extrusion layer. Since the deformation layer is made of rubber It has high elasticity, good flexibility, wear resistance and corrosion resistance. The deformation layer is deformed to make it embedded in the No. 2 card slot. The freedom of the locking block is limited by adapting the shape of the deformation layer to the No. 2 card slot. At the same time, the friction between the two and the restoring force generated by the elastic deformation of the rubber material are used to achieve fixation. At the same time, the deformation layer can play a vibration-absorbing role. By utilizing the pressure when the bolt is fixed, the deformation layer is embedded in the No. 2 card slot, thereby limiting the position of the locking block. At the same time, the setting of the deformation material plays a vibration-absorbing role, avoiding the vibration of the external environment from being transmitted to the locking block and the bolt, which will cause the bolt to loosen and the driving part on the locking block to separate from the No. 1 guide groove and the No. 2 guide groove, causing the camera image to be blurred.

[0019] Preferably, an arc groove is provided on the lower end surface of the base plate, the lower end surface of the chain link is set to be arc-shaped, the inner wall of the arc groove and the lower end surface of the support part are provided with a bonding layer, a plurality of air grooves are evenly distributed on the bonding layer, and the bonding layer is made of elastic material.

[0020] When the camera is installed on the curved surface, there is a gap between the swivel and the two sides of the chain link and the curved surface. An arc groove is opened on the lower end surface of the swivel, the lower end surface of the chain link is set to an arc shape, and a bonding layer is provided in the arc groove and on the lower end surface of the supporting part of the chain link. The chain link, swivel and the curved surface are bonded together. At the same time, the bonding layer is made of rubber, which has high elasticity, good flexibility, wear resistance and corrosion resistance. Under the action of the pre-tightening component, pressure is applied to the bonding layer through the chain and the swivel to cause it to deform. Due to the curved surface, the bonding layer is squeezed to both sides to make up for the gap between the swivel and the two sides of the chain link and the curved surface, and increase the contact area between the swivel and the chain link and the curved surface. Since the bonding layer is made of rubber, the swivel and the chain link can be kept in a pre-tightened state with the installation curved surface. At the same time, the matching block matches with the No. 1 matching groove and fixes the angle between the chain links. Maintaining the pre-tightening state can ensure that the position of the camera does not change, thereby improving the stability of the camera.

[0021] Furthermore, the deformation of the bonding layer can make the swivel seat and the connection adapt to arc surfaces of different radians. At the same time, a plurality of air grooves are evenly distributed on the bonding layer. When the pre-tightening component applies pressure to the bonding layer, the gas in the air grooves is discharged. At this time, the air grooves are in a negative pressure state, and the negative pressure of the air grooves is used to fix the swivel seat, chain links and the installation arc surface.

[0022] Preferably, the center position of the hinge part is set as the hinge point, and a plurality of protrusions are provided on the lower end surface of the hinge part. The protrusions are arranged in parallel, and the cross-section of the protrusion is triangular. The axis of the hinge direction of the protrusion and the height of the protruding teeth arranged vertically close to the support part increase from the bottom to the distal end.

[0023] When the camera mounting surface is a plane, since the lower end surface of the chain link is an arc surface and the center of the hinge part is set as the hinge point, when the No. 1 limiting block cooperates with the No. 2 matching groove, the hinge part protrudes, and a boss is set on this part of the hinge, and the cross-section of the boss is triangular. Under the action of the preload assembly, the bottom end surface of the driving part cooperates with the No. 2 guide groove, and the chain link is subjected to pressure. At the same time, pressure is applied to make the boss embed into the installation plane for fixation, thereby ensuring that the position of the chain remains unchanged.

[0024] A camera using the above-mentioned camera support assembly comprises a camera body, a support rod and a swivel seat, wherein the camera body is connected to the swivel seat through the support rod, the swivel seat is slidably connected to the upper end of the bottom plate, one side of the bottom plate is hinged to the adjacent chain link through a connecting rod, and a displacement groove is provided at the hinge, the connecting rod is slidably installed in the displacement groove, a No. 3 matching groove is provided in the bottom plate, a clamping ring is provided on the lower end surface of the swivel seat, and an annular groove is provided on the clamping ring. The clamping ring is located in the No. 3 matching groove, and the No. 3 matching groove is connected to the displacement groove, the connecting rod comprises a rotating part and a pushing part, the rotating part is connected to the adjacent chain link, the pushing part is slidably installed in the No. 3 matching groove, and a clamping block is provided on the pushing part, and the clamping block is located in the annular groove.

[0025] After selecting the installation position, the camera angle needs to be fine-tuned during the installation process to achieve a better presentation effect. The camera angle is adjusted by rotating the swivel seat. Since the swivel seat is rotatably connected to the base plate, the camera position may rotate due to environmental influences during use, such as vibrations caused by wall facilities, speeding cars and wind, resulting in a narrowing of the camera's field of view. Therefore, a ring groove is provided on the lower end face of a clamping ring at the bottom of the swivel seat. The clamping ring is coaxially rotatably installed in the No. 3 matching groove of the base plate. After the angle is adjusted, the chain is pulled by fixing the pre-tightening component to drive the adjacent base plate. When the pre-tightening component stretches and squeezes the chain link, it drives the connecting rod to slide in the displacement groove, and the sliding part of the connecting rod slides in the No. 3 matching groove, thereby driving the clamp block to slide and fit with the ring groove, and applying pressure to fix the clamp ring, thereby locking the swivel seat. The tension and pressure generated by the fixation of the pre-tightening component drive the adjacent chain links of the base plate to move, thereby making the clamp block fix the swivel seat, avoiding the problem of the swivel seat being offset due to environmental influences, resulting in a reduction in the camera's field of view, ensuring that the camera presents more key information, provides more event clues, and protects people's lives and property safety.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention uses a chain, which is composed of a plurality of hinged links. Due to the rotational connection between the links, the chain as a whole has a certain degree of flexibility. By adjusting the angles between the links, the chain can be matched with different installation surfaces, thereby realizing the installation of the camera base on arc surfaces and planes with different curvatures.

[0028] 2. The present invention uses a pre-tightening component and utilizes the pressure during bolt fixing to make the locking block cooperate with the No. 1 guide groove and the No. 2 guide groove, so as to make the chain links, the swivel seat and the pre-tightening component contact more closely on the curved surface or the plane, thereby eliminating the gaps between the chain links and avoiding the problem of changes in the field of view caused by the position offset of the camera, ensuring that the camera presents more key information, providing more event clues, and protecting people's lives and property safety.

[0029] 3. The present invention cooperates with the chain link through the pre-tightening component. When installed on the arc surface, the chain link is pulled by the cooperation of the locking block and the No. 1 guide groove, so that the matching block and the No. 1 matching groove are slidably connected to offset the stress between the chain links and avoid the displacement of the axial position of the bolt. When installed on a plane, the rotation angle is limited by the fit between the hinge groove and the upper end surface of the adjacent rotating part. At the same time, the No. 1 wedge block is interference fit with the side of the rotating part to eliminate the longitudinal gap when the chain link is connected, thereby ensuring that the camera presents more key information, provides more event clues, and protects people's lives and property safety.

[0045] Working principle: When installing the camera body 1, connect the camera body 1 and the swivel seat 12 through the support rod 11. The swivel seat 12 is rotatably installed on the base plate 2. The retaining ring 121 on the lower end surface of the swivel seat 12 is coaxially slidably connected with the No. 3 matching groove 24 on the upper end surface of the base plate 2. The retaining ring 121 rotates in the No. 3 matching groove 24 to realize the rotation of the base, thereby adjusting the angle of the camera body 1.

[0046] When the mounting surface of the camera body 1 is a plane, the chain 3 is set horizontally and fits with the mounting plane. At this time, the hinge groove 421 on the adjacent link 4 fits with the upper end surface of the hinge part 42, and the No. 1 wedge block 4211 has an interference fit on the side of the hinge part 42. The interference fit between the No. 1 wedge block 4211 and the side of the hinge part 42 eliminates the longitudinal gap when the link 4 is connected, and the chain 3 is prevented from bending. At the same time, a No. 1 wedge block 4211 is made of rubber, and the extrusion part 4213 is squeezed on the side of the hinge part 42 to deform it and expand it toward the sliding part 4212. At this time, the sliding part 4212 increases in volume and is embedded in the No. 1 slot 413 to limit the position of the hinge part 42, and vibration between the hinge part 42 and the hinge groove 421 is avoided. The locking member 542 is then locked in place by the locking means 5422 being secured to the locking member 5420 and the locking member 5420 being secured to the locking member 5420. The fixing is achieved, and at the same time, the deformation layer 5422 can play a role in buffering vibration, thereby preventing the vibration of the external environment from being transmitted to the bolt and causing loosening. The driving part 542 on the locking block 54 cannot fit with the No. 1 guide groove 522. Since the lower end surface of the chain link 4 is an arc surface, and the center of the hinge part 42 is set as a hinge point, when the No. 1 limiting block 411 cooperates with the No. 2 matching groove 412, the hinge part 42 partially protrudes, and a boss is provided on this part of the hinge part 42, and the cross-section of the boss is triangular. Under the action of the pre-tightening component, the bottom end surface of the driving part 542 cooperates with the No. 2 guide groove 523, and the chain link 4 is subjected to pressure. At the same time, the pressure is applied to make the boss embed into the installation plane for fixing, thereby ensuring that the position of the chain 3 remains unchanged. As the bolt is tightened, the bolt pushes the locking block 54 in the through groove 5 32, the driving part 542 cooperates with the No. 2 guide groove 523 during the process. Since the driving part 542 and the No. 2 guide groove 523 are both V-shaped, under the action of the side walls of the two, the guide block 52 is driven to slide in the matching part 53, push the connecting block 51, and squeeze the chain 3, so that the chain link 4, the rotating seat 12 and the pre-tightening component are in closer contact, thereby eliminating the gap between the chain links 4. As the chain links 4 are connected and continuously squeezed, when the pressure comes to the chain links 4 on both sides of the bottom plate 2, since the side edge of the bottom plate 2 and the hinged part 42 of the adjacent chain link 4 are rotatably connected through the rotating part 251 on the connecting rod 25, a displacement groove 23 is provided at the connection, and the moving groove is connected with the No. 3 matching groove 24. The pushing part 252 on the connecting rod 25 is slidably installed in the No. 3 matching groove 24.The clamping block 253 on the pushing portion 252 is located in the annular groove 122, and the chain link 4 on the side of the bottom plate 2 drives the connecting rod 25 to slide in the displacement groove 23, and the sliding portion 4212 of the connecting rod 25 slides in the No. 3 matching groove 24, thereby driving the clamping block 253 to slide and fit the annular groove 122, and applying pressure to lock the clamping ring 121, thereby fixing the rotating seat 12 to prevent the angle of the rotating seat 12 from being offset.

[0047] When the mounting surface is an arc surface, the lower end surface of the chain 3 is fitted into the mounting arc surface. At this time, the connection angle is deflected, and the driving portion 542 of the locking block 54 is aligned with the No. 1 guide groove 522, and the fixing portion 541 on the locking block 54 is bolted through the locking block 54 to connect with the wall. During the process of tightening the bolt, the bolt pushes the locking block 54 to slide downward in the through groove 532. During the process, the driving portion 542 cooperates with the No. 1 guide groove 522. Since the driving portion 542 and the No. 1 guide groove 522 are both V-shaped, under the action of the side walls of both, the guide block 52 is driven to slide in the matching portion 53, pulling the connecting block 51, thereby driving the chain 3, tightening the chain 3, making the chain link 4, the swivel seat 12 and the pre-tightening component contact more closely, thereby eliminating the gap between the chain links 4 and avoiding the camera body. 1. The problem of the change of the field of view caused by the position deviation is solved. As the bolt is tightened continuously, the deformation layer 5422 is squeezed and deformed by the action of the matching layer 5421 and the extrusion layer 5423. The freedom of the locking block 54 is limited by the shape adaptation of the deformation layer 5422 and the second card slot 5321, thereby limiting the position of the locking block 54. At the same time, the friction between the two and the restoring force generated by the elastic deformation of the rubber material are used to achieve fixation. At the same time, the deformation layer 5422 can play a role in buffering vibration, avoiding the vibration of the external environment from being transmitted to the bolt and causing it to loosen. The driving part 542 on the locking block 54 cannot fit with the second guide slot 523. During the stretching process, the chain 3 and the swivel seat 12 exert pressure on the fitting layer 22 to cause it to Deformation, due to the arc surface, the bonding layer 22 is squeezed to both sides to make up for the gap between the swivel seat 12 and the chain link 4 and the arc surface, and increase the contact area between the swivel seat 12 and the chain link 4 and the arc surface. Since the bonding layer 22 is made of rubber, the swivel seat 12 and the chain link 4 can be kept in a pre-tightened state with the installation arc surface. Maintaining the pre-tightened state can ensure that the position of the camera body 1 does not change. At the same time, a plurality of air grooves 221 are evenly distributed on the bonding layer 22. When the pre-tightening component applies pressure to the bonding layer 22, the gas in the air groove 221 is discharged. At this time, the air groove 221 is in a negative pressure state. The negative pressure of the air groove 221 is used to fix the swivel seat 12 and the chain link 4 to the installation arc surface. In the process of tightening the chain 3, displacement occurs between the chain links 4. The matching block 4122 on the supporting plate 4121 in the No. 2 matching groove 412 matches with the No. 1 matching groove 4111 corresponding to the No. 1 limiting block 411. Through the matching of the matching block 4122 and the No. 1 matching groove 4111, the stress between the chain links 4 is transferred to the matching block 4122, so as to avoid the tensile stress between the chain links 4 being transmitted to the bolt, resulting in the displacement of the axial position of the bolt. As the chain links 4 are connected and continuously tightened, when the tension comes to the chain links 4 on both sides of the bottom plate 2, since the side of the bottom plate 2 is rotatably connected with the hinged portion 42 of the adjacent chain link 4 through the rotating portion 251 on the connecting rod 25, a displacement groove 23 is provided at the connection, and the moving groove is connected with the No. 3 matching groove 24. The pushing portion 252 on the connecting rod 25 is slidably installed in the No. 3 matching groove 24.The clamping block 253 on the pushing portion 252 is located in the annular groove 122, and the chain link 4 on the side of the bottom plate 2 drives the connecting rod 25 to slide in the displacement groove 23, and the sliding portion 4212 of the connecting rod 25 slides in the No. 3 matching groove 24, thereby driving the clamping block 253 to slide and fit with the annular groove 122, and applying pressure to lock the clamping ring 121, thereby fixing the rotating seat 12, and preventing the rotating seat 12 from being offset due to the influence of the environment, causing the field of view of the camera body 1 to be reduced.

[0048] When the mounting surface of the camera body 1 is to be changed from an arc surface to a flat surface, the No. 1 limiting block 411 squeezes the No. 2 wedge block 4123 to separate the matching block 4122 from the No. 1 matching groove 4111, thereby preventing the matching block 4122 from obstructing the mutual squeezing of the chain links 4 and ensuring the normal installation of the camera body 1 on the flat surface.
