It can greatly improve the convenience of people's lives. For example, security patrol personnel can use terminals equipped with AR functions to display images or indicate routes, making it easier for operators to complete patrol work faster and better.

[0003] Existing work terminals are generally worn directly on the head via a connecting strap, and can also be used with protective devices such as safety helmets. However, the outer wall of the safety helmet itself is relatively smooth and cannot provide sufficient friction for the connecting strap. As a result, the terminal may fall off when the operator performs strenuous actions such as running and jumping, and the overall device has poor fixation. Therefore, a patrol work terminal is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 - Figure 3This utility model provides an embodiment of an inspection terminal, comprising a cap 1 for supporting the overall device. A connecting strap 5 is sleeved on the outer wall of the cap 1. The connecting strap 5 is made of plastic, has a certain elastic deformation capability, and is hollow inside to accommodate wiring. A first rotating frame 2 for supporting a display lens 3 is hinged to the left end of the connecting strap 5. A display lens 3 for displaying images is installed at the bottom end of the first rotating frame 2. The display lens 3 is a waveguide lens for displaying content. A projection device 4 for projecting images is installed at the bottom end of the display lens 3. Both the projection device 4 and the display lens 3 are existing technologies; by energizing the projection device 4, an image can be projected onto the surface of the display lens 3. Due to the existing technology and the fact that this invention does not improve upon it, it is not described in detail. A device for controlling the projection device 4 is installed at the right end of the connecting strap 5. The main unit 6 has a battery inside, which can be used to provide power for the whole device. The bottom end of the connecting strap 5 is provided with a fixing mechanism 8 for fixing the connecting strap 5. The fixing mechanism 8 includes a positioning component and a locking component. The positioning component includes a fixing buckle 81. The top end of the fixing buckle 81 is fixedly connected to the bottom end of the connecting strap 5. The fixing buckle 81 is L-shaped and can be directly snapped into the bottom end of the brim when in use. The bottom end of the main unit 6 is fixedly connected to a storage box 82 for supporting the movement of the movable buckle 85. The inner wall of the storage box 82 is slidably connected to the movable buckle 85 for fixing the main unit 6. The right end of the movable buckle 85 is fixedly connected to a fixing spring 86 for supporting the movable buckle 85. The right end of the fixing spring 86 is fixedly connected to the inside of the storage box 82. The fixing spring 86 will push the movable buckle 85 to the left at all times. The inner wall of the first rotating frame 2 is provided with a shielding component 9 for blocking strong light.

[0031] Reference Figure 1 - Figure 3The locking assembly includes a slide bar 87 for moving the movable buckle 85. The left end of the slide bar 87 is fixedly connected to the right end of the movable buckle 85. Pulling the slide bar 87 moves the movable buckle 85. The slide bar 87 passes through and is slidably connected to the right end of the storage box 82. The right end of the slide bar 87 is rotatably connected to an unlocking block 84 for moving the slide bar 87. The right end of the main unit 6 is fixedly connected to a fixing bracket 88 for restricting the movement of the unlocking block 84. The fixing bracket 88 is L-shaped. The unlocking block 84 is inserted into the inner wall of the fixing bracket 88. When the unlocking block 84 is rotated and inserted into the interior of the fixing bracket 88, Unlocking block 84 will be restricted from moving to the right. A rubber block 89 for fixing unlocking block 84 is fixedly connected to the inner wall of fixing bracket 88. A positioning groove 810 for accommodating rubber block 89 is provided at the right end of unlocking block 84. Rubber block 89 is inserted into the inner wall of positioning groove 810. When rubber block 89 is inside positioning groove 810, unlocking block 84 will be fixed and cannot move freely. A stop block 83 for blocking the bottom opening of storage box 82 is fixedly connected to the bottom end of movable buckle 85. The left surface of stop block 83 is set as a slope. When the slope is squeezed, stop block 83 will be forced to move to the right.

[0032] Reference Figure 2 - Figure 4 The shielding assembly 9 includes a second rotating frame 93 for supporting the overall shielding assembly 9. The second rotating frame 93 is hinged to the inner wall of the first rotating frame 2. The top of the second rotating frame 93 is fixedly connected to a support frame 91 for supporting the light-blocking plate 92. The inner wall of the support frame 91 is hinged to a light-blocking plate 92 for blocking strong light. Multiple sets of light-blocking plates 92 are provided, and the multiple sets of light-blocking plates 92 are symmetrically arranged with the center line of the support frame 91 as the axis of symmetry. In this case, damping shafts are used at the hinge positions to prevent the hinge positions from rotating arbitrarily. The front surface of the connecting belt 5 is equipped with a lighting lamp 7 for providing illumination, and the outer wall of the main unit 6 is equipped with a protective cover 10 for protecting the main unit 6.

[0033] Working principle: When it is necessary to fix the terminal to the cap body 1, firstly, the connecting strap 5 is put on the outer wall of the cap body 1. Then, the fixing buckle 81 is snapped into the bottom of the cap brim. Since the fixing buckle 81 is L-shaped, it can fit well with the cap brim. Then, the main unit 6 can be moved to drive the stop block 83 to press the outer wall of the cap body 1. At the same time, the outer wall of the cap body 1 will generate a reaction force to force the stop block 83 to move to the right. The stop block 83 will drive the movable buckle 85 to move to the right in sync. When the movable buckle 85 passes the bottom of the cap body 1, the fixing spring 86 will push the movable buckle 85 to cover the bottom of the cap body 1. Then, the unlocking block 84 can be rotated to drive it into the interior of the fixing frame 88. At the same time, the rubber block 89 will be snapped into the interior of the positioning groove 810. At this time, the movable buckle 85 will be restricted from moving to the right.

[0034] When the ambient light is too strong, the support frame 91 can be rotated to move the light-blocking plate 92 to the diagonal front of the display lens 3. Then the light-blocking plate 92 can be rotated for fine adjustment to ensure that the light can be blocked, so that the operator can easily view the content displayed on the surface of the display lens 3.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
