[0048] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] This utility model provides a camera mounting device for installing a camera 100 onto a supermarket shelf 200, as shown in the reference. Figure 1The shelving 200 includes a base, uprights 201, two load-bearing columns 202, multiple shelves 203, and multiple support plates 204. The uprights 201 are vertically mounted on the base and are hollow structures that extend vertically. The two load-bearing columns 202 are located at both ends of the uprights 201 and are fixedly connected to the uprights 201. Each load-bearing column 202 has multiple hanging holes 2020 spaced apart vertically. The multiple shelves 203 are horizontally spaced apart on the side of the uprights 201, and each shelf 203 has two support plates 204 vertically and symmetrically mounted at its bottom. The support plates 204 are also connected to the load-bearing columns 202.

[0050] Example 1

[0051] like Figures 2 to 4 As shown, this embodiment provides a camera fixing device, including a fixing component 1, a battery box assembly 2, a connector 3, and a bracket assembly 4. The fixing component 1 includes a fixing plate 11 and a magnet 12. The fixing plate 11 has a mounting hole 110, which includes a first hole and a second hole that are connected. The magnet 12 is disposed on one side of the fixing plate 11 and can be attracted to the surface of the shelf 200. The battery box assembly 2 includes a box body 21 with a receiving cavity and a sealing head 22. The receiving cavity is used to install batteries, and the sealing head 22 is detachably connected to the end of the box body 21 and has an insertion hole 220 communicating with the receiving cavity. The connector 3 includes a head and a rod. The rod is fixedly connected to the box body 21, and the head can pass through the first hole. The box 21 is moved horizontally, and the rod can slide into the second hole, so that the head is prevented from falling off in the second hole, and the battery box assembly 2 is connected to the fixing assembly 1. The bracket assembly 4 includes a column 41 with a first channel and a mounting arm 42 with a second channel. One end of the column 41 is connected to the fixing plate 11, and the other end extends into the second channel and is connected to the mounting arm 42. When both the battery box assembly 2 and the bracket assembly 4 are connected to the fixing assembly 1, the column 41 is against the sealing head 22. The camera 100 is inserted into the second channel from the end away from the column 41 and is snapped into the mounting arm 42. The insertion hole 220, the first channel and the second channel are connected in sequence and a cable 300 is passed through them. The two ends of the cable 300 are electrically connected to the battery and the camera 100 respectively.

[0052] The mounting plate 11 of this camera mounting device is attached to the surface of the shelf 200 by magnet 12. The magnetic attraction allows for quick installation and position adjustment, significantly improving installation efficiency. It is especially suitable for scenarios where the layout of supermarket shelves 200 changes frequently. Furthermore, the mounting holes 110 on the mounting plate 11 adopt a design with connected first and second holes. Combined with the head and rod structure of the connector 3, the battery box assembly 2 can achieve a snap-locking action through translational movement, ensuring both connection stability and easy disassembly and maintenance. At the same time, the camera 100 only needs to be inserted into the second channel and snapped onto the mounting arm 42 to complete the installation. The operation is simple and stable. The cable 300 extends from the insertion hole 220 through the first and second channels to the camera 100. The entire cable is internally wired, avoiding damage or safety hazards caused by exposure and ensuring stable and reliable power supply.

[0053] In this embodiment, one end of the column 41 is vertically connected to the fixing plate 11, and the other end extends vertically into the second channel and is connected to the mounting arm 42. When both the battery box assembly 2 and the bracket assembly 4 are connected to the fixing assembly 1, the column 41, the mounting arm 42, and the box body 21 are perpendicular to each other. By setting the column 41, the mounting arm 42, and the battery box assembly 2 to be perpendicular to each other, mutual interference can be avoided and the monitoring field of view can be expanded while ensuring a compact and stable structure.

[0054] Specifically, such as Figure 3 and Figure 5 As shown, the mounting arm 42 has a snap-fit ​​hole 421 connected to the second channel on its side. When the camera 100 is inserted into the second channel to a preset position, the snap-fit ​​hole 421 can engage and lock the snap-fit ​​piece 101 on the side wall of the camera 100. This design enables quick installation and removal of the camera 100, which can be completed with just one hand pressing down, without the need for any tools. Furthermore, the precise fit between the snap-fit ​​piece 101 and the snap-fit ​​hole 421 provides an accurate positioning reference, effectively preventing the camera 100 from shifting.

[0055] In this embodiment, the snap-fit ​​component 101 includes a spring and a snap-fit ​​block disposed at the free end of the spring. By compressing the spring, the camera 100 can be inserted into the second channel, and when the camera 100 is inserted to the predetermined position, the snap-fit ​​block can be inserted into the snap-fit ​​hole 421 under the action of the spring. The elastic snap-fit ​​method can effectively buffer external vibrations and maintain the working stability of the camera 100 while ensuring a firm installation.

[0056] It should be noted that, in addition to the spring and locking block structures described above, the latching member 101 on the camera 100 can also adopt a telescopic structure in other embodiments. When the camera 100 is inserted into the second channel, the latching member 101 is in a retracted state. When it reaches the predetermined position, the latching member 101 automatically extends, so that its end is inserted into the latching hole 421 to achieve locking. The specific structure of the latching member 101 is not limited here, as long as it can achieve latching with the latching hole 421 and ensure the stable fixation of the camera 100.

[0057] Specifically, such as Figure 2 and Figure 3 As shown, the end of the column 41 inserted into the second channel has multiple limiting holes 410 spaced apart along the insertion direction, communicating with the first channel. The outer surface of the mounting arm 42 has connecting holes 420 communicating with the second channel. The connecting holes 420 communicate with different limiting holes 410 and fasteners are inserted through them, enabling the height adjustment of the mounting arm 42 relative to the battery box assembly 2. Thus, the camera 100 can flexibly adjust the optimal viewing angle according to the actual application scenario, and the fastener insertion and fixing method ensures connection strength while making the height adjustment process simple and quick.

[0058] In this embodiment, the fastener is a screw, the limiting hole 410 is a threaded hole, the fastener passes through the connecting hole and is screwed to the column 41. The preload generated by the threaded engagement can effectively resist vibration and impact during operation, avoid loosening problems caused by long-term use, and improve the connection strength between the mounting arm 42 and the column 41. Secondly, the threaded connection method makes the fixing operation after height adjustment simpler. Only tightening the bolt is needed to complete the locking, without the need for additional tools or auxiliary parts.

[0059] Specifically, the fixing plate 11 has multiple mounting holes 110 spaced apart along its length, and the box body 21 has multiple connectors 3 correspondingly installed along its length. The heads of the multiple connectors 3 can simultaneously pass through their corresponding first holes, and by translating the box body 21, the rods of the multiple connectors 3 can simultaneously slide into their corresponding second holes. Through multi-point fixing, the force is distributed, improving the vibration and impact resistance of the entire fixing device.

[0060] In this embodiment, two connectors 3 are provided, and correspondingly, two mounting holes 110 are also provided.

[0061] In other embodiments, there may be three connectors 3. The number of connectors 3 is not specifically limited here. The number of connectors 3 can be flexibly adjusted according to the weight of the camera 100 or the battery.

[0062] In this embodiment, connector 3 is a nut screw.

[0063] In other embodiments, the connector 3 can also be a pin.

[0064] Specifically, multiple magnet blocks 12 are provided, and the multiple magnet blocks 12 are spaced apart along the length of the fixing plate 11. The arrangement of multiple magnet blocks 12 can enhance the connection strength between the fixing plate 11 and the shelf 200, making the camera 100 more stable during shooting and reducing the impact of vibration or displacement on the shooting effect.

[0065] In this embodiment, three magnet blocks 12 are provided.

[0066] In other embodiments, four magnet blocks 12 may be provided. The number of magnet blocks 12 is not specifically limited here, and can be adaptively adjusted according to the adsorption force requirements, surface characteristics of shelf 200 and installation space limitations in the actual application scenario.

[0067] In this embodiment, the magnet block 12 is mounted on the fixing plate 1 by screws.

[0068] like Figure 4 As shown, in this embodiment, the fixing plate 11 adopts a long strip flat plate structure, and its bottom surface is fixed to the top surface of the platform 203 by magnetic blocks 12. This design makes full use of the planar support characteristics of the top surface of the platform 203, and achieves stable installation through the combination of the long strip flat plate and the magnetic blocks 12, meeting the fixing requirements without additional structural modifications.

[0069] Example 2

[0070] Figures 5 to 7 Embodiment 2 is shown, in which components that are the same as or corresponding to those in Embodiment 1 are represented by the same reference numerals as those in Embodiment 1. For simplicity, only the differences between Embodiment 2 and Embodiment 1 are described. The differences are as follows:

[0071] The fixing plate 11 includes a fixing part 111 and an L-shaped hook part 112 that is bent vertically along the edge of the fixing part 111. The fixing part 111 is attached to the bottom of the platform 203 by a magnet block 12. The mounting hole 110 is provided in the fixing part 111. The outer surface of the L-shaped hook part 112 is in contact with the inner surface of the hook structure at the edge of the platform 203, so that the hook part 112 can be supported by the hook structure.

[0072] By designing the fixing plate 11 as a combined structure including a fixing part 111 and an L-shaped hook part 112, the magnet block 12 is attracted to the bottom of the platform 203, while the hook structure of the platform 203 can directly support the weight of the fixing plate 11. This effectively avoids the risk of falling off due to continuous gravity when simply relying on magnetic attraction for installation at the bottom of the platform 203. Secondly, the close fit between the L-shaped hook part 112 and the hook structure of the edge of the platform 203 provides additional lateral restraint, preventing the device from shifting or rotating when subjected to vibration or external impact, further improving the fixing effect. This design achieves a significant improvement in installation reliability through structural complementarity, retaining the convenience of magnetic attraction while overcoming the inherent defects of installation at the bottom of the platform 203.

[0073] Specifically, the L-shaped hook portion 112 is connected to the hook structure by screws. The screw connection provides additional mechanical locking force between the fixing plate 11 and the shelf hook structure, which, together with the magnetic block 12 adsorption and structural support, forms a triple fixation guarantee of "magnetic attraction, structural limiting, and mechanical fastening". Even under extreme vibration, strong external impact, or long-term gravity, it can effectively prevent the fixing plate 11 from separating from the platform 203, greatly reducing the risk of the camera 100 falling.

[0074] Example 3

[0075] Figures 8 to 10 Embodiment 3 is shown, in which components that are the same as or corresponding to those in Embodiment 1 are represented by the same reference numerals as those in Embodiment 1. For simplicity, only the differences between Embodiment 3 and Embodiment 1 are described. The differences are as follows:

[0076] The fixing plate 11 includes a supporting part 113 and a bent part 114 that bends vertically along the edge of the supporting part 113. The supporting part 113 is placed on two opposite edges of the top of the upright plate 201 along the width direction. The mounting hole 110 is provided in the supporting part 113. The bent part 114 is attracted to the side of the upright plate 201 by a magnet 12.

[0077] By setting the support portion 113 across the two sides of the top of the upright plate 201, the installation problem of the lack of a continuous support surface at the top of the upright plate 201 is solved, effectively bearing the weight of the battery box assembly 2, the bracket assembly 4 and the camera 100. Furthermore, since the magnet 12 cannot be attached to the top surface of the upright plate 201, this embodiment sets the magnet 12 on the inner side of the bending portion 114, so that it can be attached to the side of the upright plate 201, thereby improving the installation stability.

[0078] Specifically, the fixing component 1 also includes a plug-in member 13 integrally formed by a support part 131 and two clamping parts 132. The two clamping parts 132 are located at both ends of the support part 131 and are bent and extended in the same direction. The support part 131 presses against the top surface of the load-bearing column 202. The two clamping parts 132 clamp the load-bearing column 202 together by elastic force. The bearing part 113 presses against the top surface of the support part 131 and is connected to the support part 131.

[0079] By adding the connector 13, a dual stabilization mechanism is constructed: on the one hand, the support part 131 of the connector 13 provides a complete force-bearing plane for the load-bearing part 113, dispersing the local load originally concentrated on the top edge of the vertical plate 201 into a surface load-bearing area, effectively improving the force distribution; on the other hand, the two clamping parts 132 of the connector 13 clamp the load-bearing column 202 together with elasticity, improving stability.

[0080] In this embodiment, the bearing portion 113 is connected to the support portion 331 by screws, which further improves the installation stability of the fixing plate 11.

[0081] Example 4

[0082] Figures 11 to 13 Embodiment 4 is shown, in which components that are the same as or corresponding to those in Embodiment 1 are represented by the same reference numerals as those in Embodiment 1. For simplicity, only the differences between Embodiment 4 and Embodiment 1 are described. The differences are as follows:

[0083] The fixing plate 11 is attached to the bottom surface of the platform 203 by the magnet block 12. The fixing component 1 also includes a side fixing member 14, which is integrally formed by the connecting part 141, the transition part 142 and the limiting part 143. The connecting part 141 and the limiting part 143 are located at both ends of the transition part 142 and bend and extend in the same direction. The transition part 142 is located below the support plate 204. The connecting part 141 and the limiting part 143 are located on both sides of the support plate 204. The connecting part 141 is provided with a hook 1411, which is hooked into the hook hole 2020. The limiting part 143 is provided with a U-shaped groove 1430 on the side facing the connecting part 141, and the mounting arm 42 passes through the U-shaped groove 1430.

[0084] By hooking the connecting part 1411 to the hanging hole 2020, the side fixing part 14 can be effectively prevented from loosening due to vibration. At the same time, the U-shaped groove 1430 of the limiting part 143 covers and constrains the mounting arm 42, and the side wall of the U-shaped groove 1430 can support the mounting arm 42. Together with the hook 1411, they form a double insurance mechanism to avoid the magnet block 12 from not being firmly attracted due to gravity, thereby making the installation of this fixing device more stable.

[0085] Specifically, the fixing assembly 1 also includes an elastic clamping member 15, which clamps the bottom of the support plate 204 at the end away from the side fixing member 14, and the two opposing clamping arms of the elastic clamping member 15 are respectively connected to the support plate 204 and the mounting arm 42. By fixing the mounting arm 42 to the support plate 204 through the clamping member 15, the bending stress generated by the length of the mounting arm 42 is effectively distributed, preventing it from sagging and deforming due to long-term load.

[0086] In this embodiment, the two opposing clamping arms of the elastic clamping member 15 are connected to the support plate 204 and the mounting arm 42 by self-tapping screws.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. These embodiments not explicitly written should also be considered to be within the scope of this specification.
