[0041] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0042] In order to enable users to better understand the working process and functions of electronic equipment such as surveillance cameras, drone anti-guns, and detection equipment, it is usually necessary to control the electronic equipment to perform related operations during their demonstration. Taking the drone anti-gun as an example, after detecting the drone, the drone anti-gun needs to rotate relative to the bracket to aim at the drone, and send a blocking signal to the drone to cut off the drone's control signal, so that the drone loses the signal and lands or returns, thereby fully demonstrating the working process and function of the drone anti-gun.

[0043] The inventor of the present application has noticed that in order to better display electronic devices, a bracket is usually used for display. A bracket is a tool used to support and display items. It can fix items to keep them stable and easy to view. It is often used in exhibitions, shopping malls, museums and other places. The bracket mainly includes a main pole and a plurality of supporting legs, and each supporting leg is fixedly connected to the main pole in an expanded state, so that after the bracket is placed on a bearing surface such as the ground or a desktop, a triangular structure can be formed between the supporting legs, the axis of the main pole and the bearing surface to ensure the stability of the bracket and avoid damage to the electronic equipment. Finally, the electronic device is installed on the end of the main pole away from the bearing surface to prevent other structures on the bracket from hindering the normal operation of the electronic device, so that the working process of the electronic device can be fully displayed.

[0044] However, since the support legs can only be kept in an expanded state after being connected to the main pole, the bracket occupies a large area. When the bracket is moved over a short distance, it cannot be directly transported using a cart or other tools. Secondly, when the bracket needs to be moved over a long distance, the support legs need to be removed from the main pole for transportation, and then reinstalled on the main pole after arriving at the destination. The above situation makes the use and transportation of the bracket very inconvenient, and when transporting over long distances, a lot of time needs to be spent on the disassembly and assembly process.

[0045] In order to solve the problem of inconvenient use of the bracket, the inventor of the present application has designed a bracket after in-depth research. The bracket includes a main rod, a support rod and a fixed rod, and the support rods and the fixed rods are multiple and one-to-one corresponding. One end of the main rod is used to install the item to be displayed, and the other end is rotatably connected to one end of each support rod, so that the multiple support rods can rotate relative to the main rod, and when each support rod is rotated to an expanded state and fixed, the end of the support rod away from the main rod is used to abut against the bearing surface, so that the support rod, the axis of the main rod and the bearing surface form a triangle to ensure the stability of the bracket, and then ensure the stability of the item to be displayed. The two ends of the fixed rod are respectively used to connect with the support rod and the main rod at a position between the support rod and the end of the main rod away from the support rod to form two connection points, and one of the connection points is a detachable connection point, and the other connection point is a rotating connection point.

[0046] When the plurality of support rods are in an expanded state, the fixing rod is abutted between the corresponding support rod and the main rod, so that the fixing rod, part of the main rod and at least part of the support rod form a triangle, and while fixing the main rod and the support rod, the stability between the main rod and the support rod is improved, thereby improving the stability of the main rod, which can meet the requirements of the display items with higher stability. When the bracket needs to be folded, it is only necessary to separate the detachable connection points, and the corresponding fixing rod and the support rod can be rotated relative to the main rod and folded to the side of the main rod, so that the bracket can be easily folded. On the one hand, the volume of the bracket can be reduced, and it can be directly packaged and transported without removing the support rod from the main rod, saving time; on the other hand, the support rod and the fixing rod are folded to the side of the main rod, so that the bottom surface of the main rod facing away from the display item is the bottom surface of the bracket, that is, the bottom surface of the bracket is a plane structure, and the bracket can be directly placed on a cart or other tool for short-distance movement, which is more convenient to transport. In addition, the support rod and the main rod can be fixed to realize the assembly of the bracket by simply rotating the support rod from the folded state to the expanded state and reconnecting the detachable connection point. The process is simple and convenient to operate and can save the assembly time of the bracket.

[0047] The bracket disclosed in the embodiment of the present application can be used not only to display surveillance cameras, drone anti-guns, detection equipment, etc., but also to display any kind of equipment.

[0048] See also Figure 1 and Figure 2 , Figure 1 A three-dimensional diagram of a bracket provided by an embodiment of the utility model is shown. Figure 2The folded state schematic diagram of the bracket provided by the embodiment of the utility model is shown. On the one hand, the embodiment of the present application provides a bracket, the bracket 100 includes: a main rod 11, a support rod 12 and a fixing rod 13, the support rod 12 and the fixing rod 13 are multiple and are arranged one by one, the main rod 11 has a first end 111 and a second end 112 opposite to each other, the first end 111 is used to install a first to-be-displayed piece for display, one end of the plurality of support rods 12 is rotatably connected to the second end 112, so that when the plurality of support rods 12 are rotated relative to the main rod 11 to the other end to be in an expanded state and fixed to each other, the other end of the support rod 12 is used to abut against a bearing surface to place the main rod 11 on the bearing surface, and one end of the fixing rod 13 is connected to the support rod 12 to form a first connection point 17 The other end of the fixing rod 13 is connected to a position on the main rod 11 between the support rod 12 and the first end 111 to form a second connection point 18. One of the first connection point 17 and the second connection point 18 is a detachable connection point, and the other is a rotating connection point. The fixing rod 13 is used to abut between the main rod 11 and the corresponding support rod 12 when multiple support rods 12 are rotated relative to the main rod 11 to the end of the support rod 12 away from the second end 112 is in an expanded state with each other, so that a triangle is formed between the fixing rod 13, part of the main rod 11 and at least part of the support rod 12 to fix the support rod 12 and the main rod 11. The support rod 12 and the fixing rod 13 are used to rotate relative to the main rod 11 and fold to the side of the main rod 11 when the corresponding detachable connection points are disassembled and separated.

[0049] The main rod 11 is a main component on the bracket 100 for mounting and supporting the first piece to be displayed. The main rod 11 has various shapes. It can be a rectangular parallelepiped with multiple planes on its side walls, which makes it easier to mount the piece to be displayed on the side walls of the main rod 11. It can also be a cylinder with the same strength and stability in all directions of its side walls, which can withstand forces from all directions, making the main rod 11 more reliable when supporting the piece to be displayed. The main rod 11 has various sizes. When the volume of the first piece to be mounted is large, in order to enable the bracket 100 to display the first piece to be displayed, the cross-sectional area of ​​the main rod 11 is also large, so that the main rod 11 can mount and support the first piece to be displayed and ensure the stability between the bracket 100 and the first piece to be displayed.

[0050] The main pole 11 includes a first end 111 and a second end 112. The first end 111 is one of the main parts of the main pole 11 for installing a first item to be displayed. The first item to be displayed may be an electronic device such as a surveillance camera, a drone anti-gun, or a detection device. When the bracket 100 needs to install multiple items to be displayed, some of the items to be displayed may be installed on the side wall of the main pole 11. For example, when a drone anti-gun and a radar device need to be installed on the bracket 100, the drone anti-gun may be installed on the first end 111, and the radar device may be installed on the side wall of the main pole 11, so that the process of cooperation between multiple electronic devices can be displayed on one bracket 100. The multiple items to be installed may be the same type of electronic device, such as multiple surveillance cameras or multiple detection devices, or may be different types of electronic devices, such as one or more drone anti-guns and one or more detection devices.

[0051] The support rod 12 is a main component of the bracket 100 for supporting the main rod 11. In order to ensure the stability of the bracket, a bracket 100 can be provided with multiple support rods 12 for supporting the main rod 11. Specifically, the number of support rods 12 can be 3, 4, 5, etc. The multiple support rods 12 are rotatably connected to the second end 112, so that the support rods 12 can be relatively along the main rod 11. Figure 1 Direction indicated by arrow C or Figure 2 When the plurality of support rods 12 are rotated to the end away from the main rod 11 to be in an expanded state and fixed, that is, when the support rods 12 are in Figure 1 When in the state shown and fixed, one end of the support rod 12 away from the main rod 11 abuts against the bearing surface, that is, the bracket 100 is placed on the bearing surface, so that the support rod 12 abuts against the bearing surface, and then a triangle is formed between the axis of the support rod 12 and the main rod 11 and the bearing surface to support the main rod 11 and maintain stability.

[0052] The fixing rod 13 is a main component on the bracket 100 for fixing the main rod 11 and the support rod 12. Since the support rod 12 and the second end 112 are rotatably connected, it is necessary to set the fixing rod 13 to abut between the main rod 11 and the support rod 12 so that the main rod 11 and the support rod 12 can be fixed to each other when the support rod 12 rotates to Figure 1 One end of the fixing rod 13 is connected to the support rod 12, and the other end is connected to the main rod 11, and the second connection point 18 formed by the connection between the fixing rod 13 and the main rod 11 is located between the first end 111 and the connection point between the support rod 12 and the second end 112, that is, when the bracket 100 is in the state shown. Figure 1 In the state shown, when the device is placed on a bearing surface and one end of the support rod 12 abuts against the bearing surface, at least a portion of the fixing rod 13 is located above the support rod 12 , making the installation of the fixing rod 13 more convenient.

[0053] The first connection point 17 indicates the connection position between the fixed rod 13 and the support rod 12, rather than a specific point on the fixed rod 13 or the support rod 12. That is, the position where the fixed rod 13 and the support rod 12 are connected is the first connection point 17. Similarly, the second connection point 18 indicates the connection position between the fixed rod 13 and the main rod 11. In addition, one of the first connection point and the second connection point is a detachable connection point, and the other is a rotating connection point. Specifically, when the first connection point 17 is a detachable connection point, the second connection point 18 is a rotating connection point. At this time, Figure 1 As shown, when the bracket 100 is folded, the fixing rod 13 and the support rod 12 are separated first, and then the fixing rod 13 is rotated in the direction indicated by the arrow C to fold it to the side of the main rod 11, and finally the support rod 12 is rotated in the direction indicated by the arrow C to fold the support rod 12 to the side of the main rod 11; when the first connection point 17 is a rotating connection point, the second connection point 18 is a detachable connection point. At this time, when the bracket 100 is folded, the fixing rod 13 and the main rod 11 are separated first, and then the fixing rod 13 is rotated in the direction indicated by the arrow C to fold it to the side of the main rod 11. Figure 2 Rotate the fixing rod 13 in the direction indicated by the arrow D to fold it to the side of the corresponding support rod 12, and finally Figure 1 The support rod 12 is rotated in the direction indicated by the middle arrow C, so that the support rod 12 is folded on the side of the main rod 11. The detachable connection points can be connected by a snap connection, or by a connection piece such as a screw or a bolt. The rotating connection points can be connected by a connection piece such as a screw, a hinge, or a latch.

[0054] In addition, the detachable connection point can not only have a detachable function, but also have a rotation function. For example, when the second connection point 18 is a detachable connection point, if the second connection point 18 is connected, the main rod 11 and the fixed rod 13 are fixed to each other, the fixed angle between the main rod 11 and the fixed rod 13 cannot be changed. Since the distance between the connection point formed by the support rod 12 and the main rod 11 and the second connection point 18 and the length of the fixed rod 13 are fixed, the size and shape of the triangle formed by the fixed rod 13, part of the main rod 11 and at least part of the support rod 12 cannot be changed, that is, the angle between the main rod 11 and the support rod 12 cannot be changed, which makes the bracket 100 unable to be adjusted according to different display environments. Therefore, in order to improve the flexibility of the bracket 100, the main rod 11 and the fixed rod 13 can also be rotatably connected so that the angle between the main rod 11 and the fixed rod 13 is adjustable, thereby being able to change the size and shape of the triangle formed by the fixed rod 13, part of the main rod 11 and at least part of the support rod 12.

[0055] Similarly, in addition to the function of rotation, the rotating connection point can also have a detachable function. For example, when the first connection point 17 is a rotating connection point, in order to enable the bracket 100 to adjust the angle between the main rod 11 and the support rod 12 according to the site requirements, a plurality of different connection points can be set on the support rod 12 for the fixed rod 13 to connect, so that the distance from the first connection point 17 to the end of the support rod 12 can be changed. At this time, if the connection points on the support rod 12 are independent of each other, when changing the position of the first connection point 17, the fixed rod 13 and the support rod 12 need to be separated first and then reconnected. Therefore, the first connection point 17 also needs to have a detachable function. Further, when the rotating connection point also has a detachable function, the fixed rod 13 can be directly removed from the bracket 100, thereby making the folding of the support rod 12 more convenient.

[0056] like Figure 1 As shown, the straight line where the connection point formed by the support rod 12 and the main rod 11 and the second connection point 18 are located can be parallel to the axis of the main rod 11, so that when the fixing rod 13 abuts between the main rod 11 and the support rod 12, the whole is located above the support rod 12, so that the end of the fixing rod 13 directly abuts against the support rod 12, thereby improving the structural strength between the main rod 11, the support rod 12 and the fixing rod 13, and thus improving the stability of the bracket 100; it may also not be parallel to the axis of the main rod 11, so that when the support rod 12 is folded to the side of the main rod 11, there is no interference between the connection structure on the main rod 11 for connecting the fixing rod 13 and the support rod 12, and the support rod 12 can be directly folded to the side of the main rod 11.

[0057] When the initial state of the bracket 100 is Figure 2 When the bracket 100 is installed, the support rod 12 is first rotated in the direction indicated by the arrow D, so that the plurality of support rods 12 are in an expanded state, that is, Figure 1 The fixed rod 13 is rotated to the corresponding expanded state between the support rod 12 and the main rod 11, so that the fixed rod 13 abuts between the support rod 12 and the main rod 11, and finally the detachable connection points are connected, so that a triangle is formed between the fixed rod 13, part of the main rod 11 and at least part of the support rod 12, thereby fixing the main rod 11 and the support rod 12. When the initial state of the bracket 100 is Figure 1 In the state shown, when the bracket 100 is folded, the detachable connection point is first separated, and then the fixing rod 13 is rotated and folded to the side of the support rod 12 or the main rod 11, and finally the support rod 12 is rotated in the direction indicated by the arrow C to fold it to the side of the main rod 11, that is, Figure 2 Shown in folded state.

[0058] The above embodiment connects the support rod 12 to the second end 112 of the main rod 11 by rotation. On the one hand, when the bracket 100 is folded or installed, it is only necessary to rotate the support rod 12, and there is no need to remove the support rod 12 from the main rod 11 and then reinstall it, which makes the use and transportation of the bracket 100 more convenient and saves time; on the other hand, the support rod 12 is connected to the second end 112, and after the support rod 12 is folded to the side of the main rod 11, the support rod 12 and the main rod 11 can overlap as much as possible, that is, when the length of the main rod 11 is relatively small, after the bracket 100 is folded, the main rod 11 can completely overlap with the support rod 12, so that the length of the support rod 12 is the same as the length of the bracket 100; when the length of the main rod 11 is relatively large, after the bracket 100 is folded, the support rod 12 can completely overlap with the main rod 11, so that the length of the main rod 11 is the same as the length of the bracket 100, thereby reducing the volume of the bracket 100 and making transportation more convenient. Secondly, the main rod 11 and the support rod 12 are fixed by the fixing rod 13. On the one hand, the fixing rod 13, part of the main rod 11 and at least part of the support rod 12 form a triangle, so that the structure between the main rod 11 and the support rod 12 is more stable; on the other hand, the second connection point 18 is located between the first end 111 and the connection point between the support rod 12 and the second end 112, so that when the bracket 100 is in the expanded state, the second connection point 18 is located above the support rod 12, and the connection status of this position can be directly observed during installation, which makes the connection more convenient and effectively improves the installation efficiency. In addition, after the bracket 100 is folded, the bottom surface of the second end 112 is the bottom surface of the bracket 100, that is, the bottom surface of the bracket 100 is a flat structure, and the bracket 100 can be directly placed on a cart or other tool for short-distance movement, which is more convenient for transportation.

[0059] When the positions of the first connection point and the second connection point remain unchanged, the triangle formed by the fixed rod, part of the main rod and at least part of the support rod is also fixed, that is, the angle formed between the main rod and the support rod remains unchanged. After the support rod is in an expanded state and fixed, the overall size of the bracket remains unchanged, and the bracket cannot be adjusted according to different display venues, and the adaptability is low. In some embodiments of the present application, such as Figure 1 and Figure 3 As shown, Figure 3 Shows Figure 1 In the enlarged schematic diagram at point A, a first adjustment portion 121 is provided on the support rod 12, and the first adjustment portion 121 has a plurality of third connection points 122 along the extension direction of the support rod 12, and the fixing rod 13 is used to connect with different third connection points 122 to adjust the fixed angle between the main rod 11 and the support rod 12.

[0060] The first adjusting portion 121 is provided with a plurality of third connection points 122 for adjusting the connection position between the fixing rod 13 and the support rod 12. The third connection points 122 are provided along the extension direction of the support rod 12. The fixing rod 13 is connected to different third connection points 122, so that the distance between the position connected to the fixing rod 13 on the support rod 12 and the end of the support rod 12 close to the second end 112 in the extension direction of the support rod 12 changes, even if Figure 1 The length L1 shown in FIG. Figure 1 As shown, since the length of the fixing rod 13 and the distance between the position on the main rod 11 where the fixing rod 13 is connected and the position where the fixing rod 13 is connected to the support rod 12 remain unchanged, in the triangle formed between the fixing rod 13, the main rod 11 and the support rod 12, when the length L1 shown in the figure increases, the angle of the relative internal angle of the support rod 12 will also increase, that is, the angle between the fixing rod 13 and the main rod 11 will increase. When the axis of the main rod 11 remains stationary, the fixing rod 13 needs to be rotated in the direction indicated by the arrow C to adjust the angle between the fixing rod 13 and the main rod 11. At this time, in order to enable the fixing rod 13 to be connected to the support rod 12, the support rod 12 also needs to be rotated in the direction indicated by the arrow C, thereby reducing the angle between the support rod 12 and the main rod 11. Similarly, when the length L1 shown in the figure decreases, the fixing rod 13 and the support rod 12 both rotate, thereby increasing the angle between the support rod 12 and the main rod 11.

[0061] The above-mentioned embodiment arranges a first adjustment portion 121 on the support rod 12, and arranges a plurality of third connection points 122 on the first adjustment portion 121 to adjust the fixed angle between the main rod 11 and the support rod 12, and then adjusts the expansion degree of the support rod 12, so that the overall height and footprint of the bracket 100 change, thereby adapting to the needs of different exhibition venues. For example, when the bearing surface for installing the bracket 100 in the exhibition venue is small, the angle between the main rod 11 and the support rod 12 is adjusted to reduce the expansion degree of the support rod 12, thereby reducing the footprint of the bracket 100, and the bracket 100 has higher flexibility and stronger adaptability.

[0062] In some embodiments of the present application, Figure 1 and Figure 3As shown, the third connection point 122 is a first through hole 123, and the first through hole 123 is used for the first fastener 124 to pass through and connect with the fixing rod 13, so that the fixing rod 13 is connected with the support rod 12. The first adjustment portion 121 is provided with a plurality of first through holes 123 along the extension direction of the support rod 12, and the first through holes 123 correspond to the third connection points 122 one by one, that is, when the first adjustment portion 121 has two first through holes 123 arranged along the extension direction of the support rod 12, the first adjustment portion 121 has two third connection points 122; when the first adjustment portion 121 has three first through holes 123 arranged along the extension direction of the support rod 12, the first adjustment portion 121 has three third connection points 122, and so on.

[0063] When adjusting the third connection point 122 connected to the fixed rod 13, the fixed rod 13 needs to be separated from the first through hole 123 corresponding to the currently connected third connection point 122, that is, the fixed rod 13 needs to be removed from the support rod 12, and then the fixed rod 13 needs to be reconnected to the new first through hole 123, so that the fixed rod 13 is connected to the new third connection point 122. Therefore, the first connection point 17 formed by the connection between the fixed rod 13 and the support rod 12 has a detachable function, and the first connection point 17 can be used as a detachable connection point, and the second connection point 18 can be used as a rotating connection point. Of course, the connection between the fixed rod 13 and the support rod 12 can also be a rotating connection, for example, the first fastener 124 is a connecting member such as a screw, a hinge, a latch, etc. After the fixed rod 13 and the support rod 12 are connected using the first fastener 124, the fixed rod 13 can rotate relative to the support rod 12. At this time, the first connection point 17 can also be used as a rotating connection point, and the second connection point 18 can be used as a detachable connection point.

[0064] In the above-mentioned embodiment, the first through hole 123 is used as the third connection point 122, and the position of each first through hole 123 on the support rod 12 is fixed, that is, the distance between each first through hole 123 and the two ends of the support rod 12 is fixed. When it is necessary to adjust the third connection point 122 connected to the fixing rod 13, the length L1 shown in the figure can be accurately adjusted to make the length L1 shown in the figure on all support rods 12 equal, thereby ensuring the stability of the bracket 100 and making the angle adjustment between the main rod 11 and the support rod 12 more convenient.

[0065] In some embodiments of the present application, Figure 1 and Figure 4 As shown, Figure 4A schematic diagram of the partial structure of the bracket provided by an embodiment of the utility model is shown, a strip hole 125 is opened on the first adjustment portion 121 along the extension direction of the support rod 12, and multiple connection positions on the strip hole 125 form multiple third connection points 122. The strip hole 125 is used for the second fastener 126 connected to the fixing rod 13 to pass through and slide inside, so that when the second fastener 126 is tightened, the fixing rod 13 is fixed to the corresponding third connection point 122.

[0066] like Figure 4 As shown, the strip hole 125 is a hole with a long and narrow shape, which is characterized by its length being greater than its width, that is, the length L2 shown in the figure is greater than the width W shown in the figure, and its shape can be a rectangle, a polygon with a certain length, etc. The second fastener 126 can be a combination of a screw and a nut, that is, after aligning the connection hole on the fixing rod 13 with the strip hole 125, after the screw is passed through the strip hole 125, the nuts are locked to the two ends of the screw, and the screw is slid so that the screw is located at different positions of the strip hole 125, so that the fixing rod 13 is connected to different third connection points 122, and then the nut is locked to fix the fixing rod 13 to the corresponding third connection point 122; it can also be a bolt, and a threaded hole can be opened on the fixing rod 13, and after the bolt is passed through the strip hole 125, it is threadedly connected with the threaded hole on the fixing rod 13. When adjusting the connection position of the fixing rod 13, the bolt is loosened, and the bolt can be slid in the strip hole 125 to adjust the connection position of the fixing rod 13, and then the bolt is tightened at the corresponding position to fix the fixing rod 13 to the corresponding third connection point 122.

[0067] The above embodiment provides the strip hole 125 so that when adjusting the connection position of the fixing rod 13, it is only necessary to loosen the second fastener 126 and slide the second fastener 126 in the strip hole 125. When the fixing rod 13 is adjusted to the desired position, the second fastener 126 is tightened to fix the fixing rod 13 to the corresponding third connection point 122, thereby completing the adjustment process of the fixing rod 13 without removing the fixing rod 13 from the support rod 12 and reinstalling it, which makes the adjustment more convenient. In addition, any connection position on the strip hole 125 can be used as the third connection point 122, and fine adjustments can be made, that is, the second fastener 126 can be moved a very small distance during the adjustment process, and the angle between the main rod 11 and the support rod 12 can be set to more different values, so that the bracket 100 has higher flexibility and stronger adaptability.

[0068] like Figure 1As shown, when the main rod is a cylinder, its side surface is a curved surface. In order to make the connection between the fixing rod and the main rod more convenient, a corresponding fixing piece can be set on the side wall of the main rod. At the same time, in order to improve the stability of the main rod and the support rod, the fixing rod can be abutted between the main rod and the support rod, that is, the center of the fixing piece and the connection point between the support rod and the main rod are set on the same straight line, and the straight line is parallel to the axis of the main rod. At this time, in the process of folding the support rod and the fixing rod, there is interference between the support rod and the fixing piece, which makes the support rod unable to fold to the side of the main rod.

[0069] In order to avoid the interference problem, in some embodiments of the present application, Figure 5 and Figure 6 As shown, Figure 5 Another perspective view of the bracket provided by the embodiment of the utility model is shown. Figure 6 A schematic diagram of a folded state of another bracket provided by an embodiment of the utility model is shown, a plurality of fixing members 113 are arranged on the main rod 11 between the support rod 12 and the first end 111, the fixing members 113 are arranged one-to-one with the fixing rod 13, the fixing members 113 and one end of the fixing rod 13 are connected to form a second connection point 18, and a receiving groove 114 is opened on the fixing member 113 along the extension direction of the main rod 11, and the receiving groove 114 is used to accommodate at least part of the support rod 12 when the support rod 12 rotates relative to the main rod 11 and folds to the side of the main rod 11.

[0070] The fixing member 113 is a main structure on the main rod 11 for connecting the fixing rod 13. The structure of the fixing member 113 is various and can be as follows: Figure 5 The structure shown is composed of two plate-like structures, and the two plate-like structures are arranged along the extension direction of the main rod 11, so that a receiving groove 114 is formed between the two plate-like structures along the extension direction of the main rod 11; it can also be a block-like structure, and the block-like structure is provided with a receiving groove 114 along the extension direction of the main rod 11. The receiving groove 114 can be a U-shaped groove, a V-shaped groove or the like, so that when the support rod 12 is folded to the side of the main rod 11, at least part of the support rod 12 can be inserted into the receiving groove 114, thereby ensuring that there is no interference between the support rod 12 and the fixing member 113.

[0071] In addition, if Figure 2 As shown, when the outer side of the support rod 12 is also wrapped with a decorative piece 14 for protecting the support rod 12 or beautifying the appearance of the bracket 100, the side wall of the fixing piece 113 can be inserted into the gap between the decorative piece 14 and the support rod 12. Of course, when the width of the receiving groove 114 is larger, the decorative piece 14 and the support rod 12 can also be accommodated in the receiving groove 114 together.

[0072] The above embodiment provides the fixing member 113, so that the fixing rod 13 can be more conveniently installed on the main rod 11, and the receiving groove 114 is provided on the fixing member 113 along the extension direction of the main rod 11, so that when the support rod 12 is folded to the side of the main rod 11, it can be at least partially inserted into the receiving groove 114, avoiding interference between the support rod 12 and the fixing member 113. In addition, the receiving groove 114 can also limit the position of the support rod 12 after folding upward, and when the side wall of the main rod 11 is also provided with a second piece to be displayed, it can effectively avoid the collision between the support rod 12 and the second piece to be displayed, thereby avoiding damage to the second piece to be displayed.

[0073] In order to ensure that the support rod is more stable after it abuts against the bearing surface, a mounting plate is usually set at the end of the support rod away from the main rod, so that the support rod and the bearing surface are connected through the mounting plate, that is, the contact area between the bracket and the bearing surface is increased to enhance the stability of the bracket. If the mounting plate is fixedly connected to the support rod, the angle between the support rod and the mounting plate is fixed, and when the angle between the support rod and the main rod is adjusted, the angle between the support rod and the bearing surface will change accordingly, making it impossible for the mounting plate to fit the bearing surface, thereby affecting the stability of the bracket.

[0074] In some embodiments of the present application, Figure 1 and Figure 7 As shown, Figure 7 Shows Figure 1 In the enlarged schematic diagram at point B, the bracket 100 also includes a mounting plate 15, one side of the mounting plate 15 is connected to the end of the support rod 12 facing away from the main rod 11, and the other side of the mounting plate 15 is used for detachable connection with the bearing surface, and a second adjustment portion 151 is provided on the mounting plate 15, and a fourth connection point 152 and a plurality of fifth connection points 153 are provided on the second adjustment portion 151. The support rod 12 is rotatably connected to the fourth connection point 152 and is used for fixed connection with different fifth connection points 153 to adjust the fixed angle between the support rod 12 and the mounting plate 15, so that the mounting plate 15 and the bearing surface are mutually attached and connected.

[0075] The mounting plate 15 is used to increase the contact area between the support rod 12 and the bearing surface to improve the stability of the bracket 100. The mounting plate 15 can be connected to the bearing surface by means of magnetic attraction, clamping, etc., that is, after the bracket 100 is placed on the bearing surface, the mounting plate 15 is connected to the bearing surface, which can prevent the bracket 100 from moving, effectively protect the stability of the bracket 100, and avoid the bracket 100 from tipping over due to the shaking of the bearing surface, and the damage to the first display item. The above connection method is simple and easy to operate, and the bracket 100 can be fixed to the bearing surface very conveniently; the mounting hole can also be opened on the mounting plate 15, and connected to the bearing surface by bolts, screws and other connecting parts, which can further improve the firmness of the connection between the bracket 100 and the bearing surface, and can effectively avoid the problem of the bracket 100 tipping over due to collision.

[0076] The position where the fourth connection point 152 on the second adjustment part 151 is located can be connected to the support rod 12 through a connection piece such as a hinge, a latch, a screw, etc. For example, a through hole is provided at the position where the fourth connection point 152 is located on the second adjustment part 151, and the connection piece is passed through the through hole and connected to the support rod 12. The fifth connection point can be an independent through hole, that is, multiple through holes are provided on the second adjustment part 151 as multiple fifth connection points, so that the angle between the support rod 12 and the mounting plate 15 is more controllable.

[0077] When the angle between the main rod 11 and the support rod 12 changes, the angle between the support rod 12 and the bearing surface will also change accordingly. In order to keep the mounting plate 15 in contact with the bearing surface, a second adjustment portion 151 is provided on the mounting plate 15. The fourth connection point on the second adjustment portion 151 is rotatably connected to the support rod 12. When adjusting the angle between the support rod 12 and the mounting plate 15, it is only necessary to rotate the support rod 12 relative to the mounting plate 15 so that the support rod 12 is connected to a different fifth connection point 153 to adjust the angle between the support rod 12 and the mounting plate 15, thereby making the mounting plate 15 fit the bearing surface.

[0078] In the above embodiment, the mounting plate 15 is provided to increase the contact area between the bracket 100 and the bearing surface, thereby effectively improving the stability of the bracket 100. The second adjusting portion 151 is provided on the mounting plate 15 to adjust the angle between the support rod 12 and the mounting plate 15. On the one hand, it is ensured that when the angle between the main rod 11 and the support rod 12 changes, the angle between the support rod 12 and the mounting plate 15 can be adjusted so that the mounting plate 15 fits the bearing surface, thereby ensuring the stability of the bracket. On the other hand, the fixed angle between the support rod 12 and the mounting plate 15 can be adjusted so that the bracket 100 is suitable for bearing surfaces with different inclination angles, thereby effectively improving the flexibility of the bracket 100. In addition, when adjusting the angle between the support rod 12 and the mounting plate 15, the support rod 12 only needs to be rotated relative to the mounting plate 15 with the fourth connection point 152 as the rotation center, so that the support rod 12 is connected to different fifth connection points 153, and the adjustment process can be completed. There is no need to remove the mounting plate 15 from the support rod 12 and then reinstall it on the support rod 12, so the adjustment is more convenient.

[0079] In order to facilitate the adjustment of the fixed angle between the support rod and the mounting plate, in some embodiments of the present application, such as Figure 7 As shown, an arc-shaped hole 154 is opened on the second adjustment portion 151 with the fourth connection point 152 as the center, and multiple connection positions on the arc-shaped hole 154 form multiple fifth connection points 153. The arc-shaped hole 154 is used for the third fastener 155 connected to the support rod 12 to pass through and slide inside, so that when the third fastener 155 is tightened, the support rod 12 is fixed to the corresponding fifth connection point 153.

[0080] Since the distance between the two positions on the support rod 12 for connecting with the fourth connection point 152 and the fifth connection point 153 is fixed, in order to ensure that the support rod 12 can be accurately connected with the fifth connection point 153, it is necessary to ensure that the distance between each fifth connection point 153 and the fourth connection point 152 is equal, that is, each fifth connection point 153 is located on the same arc line with the fourth connection point 152 as the center. An arc hole 154 can be set on the second adjustment portion 151, and the angle between the support rod 12 and the mounting plate 15 can be adjusted and fixed by a third fastener 155. The third fastener 155 is basically the same as the second fastener in type and working principle, and will not be repeated here.

[0081] The above embodiment provides the arc hole 154, so that when adjusting the angle between the support rod 12 and the mounting plate 15, it is only necessary to loosen the third fastener 155, slide the third fastener 155 in the arc hole 154, and then tighten the third fastener 155 to fix the support rod 12 to the corresponding fifth connection point 153, and the adjustment can be completed without removing the mounting plate 15 from the support rod 12 and reinstalling it, which makes the adjustment more convenient. In addition, any connection position on the arc hole 154 can be used as the fifth connection point 153, which can be fine-tuned, that is, the moving distance of the third fastener 155 can be very small, and the bracket 100 has higher flexibility and stronger adaptability.

[0082] In order to make the short-distance movement of the bracket more convenient, in some embodiments of the present application, Figure 1 As shown, a universal wheel 16 is provided on the second end 112. The universal wheel 16 is a wheel that can rotate freely and allow movement in multiple directions, and can also be called a movable wheel or a steering wheel. While being perpendicular to the ground, it can also rotate freely on the horizontal plane. During short-distance transportation, after the support rod 12 is folded on the side of the main rod 11, the universal wheel 16 on the second end 112 is perpendicular to the ground, and the bracket 100 can be directly pushed to rotate the universal wheel 16, thereby moving the bracket 100. The above-mentioned embodiment enables the bracket 100 to move by itself by providing the universal wheel 16. During short-distance transportation, there is no need to use tools such as a cart, and the transportation of the bracket 100 is more convenient. In addition, the universal wheel 16 can rotate freely on the horizontal plane. In the process of moving the bracket 100, the moving direction of the bracket 100 can be freely changed, and the transportation of the bracket 100 is more flexible.

[0083] According to another aspect of the embodiment of the present application, a display device is also provided, such as Figure 8 As shown, Figure 8 A stereoscopic diagram of a display device provided by an embodiment of the utility model is shown, wherein the display device 200 comprises a first display item 21 and a bracket 100 as described in any of the above embodiments, wherein the first display item 21 is detachably connected to the first end 111. One or more first display items 21 may be provided on the first end 111, and the first display item 21 may be an electronic device such as a surveillance camera, a drone counter-gun, or a detection device. Multiple first display items 21 may be the same, for example, multiple surveillance cameras or multiple detection devices, or may be different, for example, one or more surveillance cameras and one or more detection devices, etc.

[0084] In some embodiments of the present application, Figure 8 and Fig. 9 As shown, Fig. 9The folded state schematic diagram of the display device provided by the embodiment of the utility model is shown. The display device 200 also includes a plurality of second pieces to be displayed 22, each of which is arranged at intervals around the side wall of the main rod 11. When the support rod 12 is rotated relative to the main rod 11 and folded to the side of the main rod 11, it is located between two adjacent second pieces to be displayed 22. Taking the first piece to be displayed 21 as a drone anti-gun as an example, the drone anti-gun can work in conjunction with the radar device when in use. Specifically, the radar device can detect the drone and obtain relevant information about the drone, and then transmit the relevant information of the drone to the drone anti-gun, so that the drone anti-gun can transmit a blocking signal to the drone after obtaining the relevant information of the drone, so as to make the drone return or land.

[0085] In order to fully demonstrate the working process of the drone anti-gun and the radar device, the drone anti-gun and the radar device can be installed on the same bracket 100. At this time, the drone anti-gun can be installed on the first end 111 as the first to-be-exhibited piece 21, and the radar device can be installed on the side wall of the main rod 11 as the second to-be-exhibited piece 22. In addition, when the length of the support rod 12 is relatively large, the support rod 12 can be located between two adjacent second to-be-exhibited pieces 22 after being folded, which can avoid interference between the support rod 12 and the second to-be-exhibited piece 22, and avoid collision between the support rod 12 and the second to-be-exhibited piece 22, thereby avoiding damage to the second to-be-exhibited piece 22.
