Description

Technical Field

[0001] The utility model relates to the technical field of display terminals, in particular to a display terminal for patrol monitoring. Background Technique

[0002] Monitoring is an important part of the security prevention system. The traditional monitoring system includes a front-end camera, a transmission cable, and a video monitoring platform. The cameras can be divided into network digital cameras and analog cameras, which can be used for collecting front-end video image signals. It is a comprehensive system with strong prevention capabilities. Video monitoring is widely used in many occasions due to its intuitive, accurate, timely, and rich information content. When performing security monitoring, not only video shooting is required, but also corresponding display terminal devices are needed to display data. The data terminal device is a device at one end or the other end during data transmission, such as a computer display terminal or other terminals. The computer display terminal is an input and output device of the computer system.

[0003] Due to the need for mobility, the existing display terminals for patrol monitoring are commonly of a handheld structure. However, the handheld patrol display terminals are often dropped and damaged due to the negligence of the user during use. Therefore, some patrol display terminals are often provided with a lifting rope to further ensure the stability during holding. However, the improvement of stability by such soft materials is often limited. Therefore, we propose a display terminal for patrol monitoring to solve the problems encountered above.

[0023] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-6 As shown, a display terminal for patrol monitoring includes a handheld display terminal 1, and an installation frame 2 is fixedly connected to one side of the handheld display terminal 1; a fixing component, the fixing component includes a fixed pin 3 fixedly connected inside the installation frame 2, square grooves 4 are opened on both the upper and lower sides of one side of the installation frame 2, and the same rotating frame 5 is arranged in the two square grooves 4. The rotating frame 5 is rotatably connected to the outside of the fixed pin 3. Grooves 6 are opened at the top and bottom of the rotating frame 5, positioning blocks 7 are circumferentially distributed on the grooves 6, and chucks 8 are also fixedly connected to both the upper and lower sides of the outside of the fixed pin 3. Card slots 9 are opened on the chucks 8, and the card slots 9 are circumferentially distributed. Step grooves 10 are opened on both the upper and lower sides of one side of the rotating frame 5, slide blocks 11 are slidably connected in the step grooves 10, springs are arranged on the outside of the slide blocks 11, and one ends of the two slide blocks 11 are fixedly connected to the same bent frame 12. The installation frame 2 is used to connect the handheld display terminal 1 and the fixing component. The fixed pin 3 is used to position the rotation center of the rotating frame 5. The groove 6 is used to facilitate the installation and accommodation of the chuck 8. The positioning block 7 is used to cooperate with the card slot 9 to lock the rotating frame 5 to a specific angle of rotation to prevent it from deflecting randomly. The step groove 10 is used to facilitate the sliding of the slide block 11 therein. A limit block is arranged at one end of the slide block 11 to prevent it from disengaging from the step groove 10. One end of the spring abuts against one side surface of the limit block. When the bent frame 12 is pulled outward to make the slide block 11 slide in the step groove 10, the spring is in a compressed state, which is used to ensure that the bent frame 12 always receives a pulling force towards the side close to the installation frame 2 to ensure the contact between the bent frame 12 and the hand.

[0025] Furthermore, the maximum width of the square groove 4 is less than the thickness of the installation frame 2, and the minimum width of the square groove 4 is adapted to the thickness of the rotating frame 5. By limiting the width of the square groove 4, the rotation direction of the rotating frame 5 is limited, so that it can only rotate to the rear side of the handheld display terminal 1 for convenient holding, and can only be rotated forward to a position where it is flush with the handheld display terminal 1 to facilitate the placement and holding of the handheld display terminal 1.

[0026] Further, one end of the rotating frame 5 is an arc surface. Two circular holes 13 adapted to the outer diameter of the fixing pin 3 are provided on the rotating frame 5. The circular holes 13 facilitate the connection and disassembly of the rotating frame 5 and the fixing pin 3. The arc surface can prevent interference with the surface of the square groove 4 during rotation, facilitating installation and use.

[0027] Further, four positioning blocks 7 are provided in total. The angle between the connecting lines of the centers of adjacent positioning blocks 7 and the center of the circular hole 13 is ninety degrees. Limiting the position of the positioning blocks 7 can conveniently limit the rotation angle of the rotating frame 5, so that the rotating frame 5 can only rotate ninety degrees each time to maintain a stable state, thereby positioning the rotating frame 5 during use and facilitating the use of the user.

[0028] Further, the shape of the positioning block 7 is a hemisphere, and the cross-section of the card slot 9 is adapted to the shape of the positioning block 7. When the positioning block 7 rotates with the rotating frame 5 and is embedded in the card slot 9, the resistance provided by the card slot 9 to it increases the difficulty of further rotating the rotating frame 5, reminding the user that the rotating frame 5 has rotated in place and facilitating use.

[0029] Further, rubber pads 14 are provided on the adjacent surfaces of the bent frame 12 and the rotating frame 5. The rubber pads 14 can reduce the pressure when the bent frame 12 presses the user's hand, improving the comfort of use.

[0030] When the present utility model is specifically implemented: When it is necessary to hold the handheld display terminal 1, manually push the rotating frame 5 to rotate it around the fixing pin 3. During rotation, the positioning block 7 is detached from the card slot 9 under the action of pressure and slides on the surface of the chuck 8, while forcing the surface of the chuck 8 to deform until the positioning block 7 is embedded in another card slot 9. At this time, the user can obviously feel an increase in resistance, indicating that the rotating frame 5 has rotated to an appropriate angle. At this time, the user pulls out the bent frame 12 outward and inserts the hand into the gap between the bent frame 12 and the rotating frame 5. During the pulling process, the slider 11 will slide in the stepped groove 10 and compress the spring. Then, when the user releases the hand, under the elastic force of the spring, the slider 11 will move in the direction of retracting into the stepped groove 10 and drive the bent frame 12 to move, squeezing the user's hand to achieve stable fixation.

[0031] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to only the specific implementation manners. Obviously, according to the content of this specification, many modifications and changes can be made. This specification selects and specifically describes these embodiments to better explain the principle and practical application of the present utility model, so that those skilled in the relevant technical field can understand and utilize the present utility model well. The present utility model is only limited by the claims and their full scope and equivalents.
