Description

Technical Field

[0001] This utility model relates to the field of protective cover technology, and in particular to an exit protective cover with an adjustment mechanism. Background Technology

[0002] A face shield is a protective device worn by some people when they go out. It is usually used to prevent the effects of harmful substances such as air pollution and ultraviolet radiation on the body, thereby providing protection for the face and making the body more comfortable when going out.

[0003] However, when using the protective cover, sometimes the cover may be damaged or its surface may be stained, making it inconvenient to disassemble and maintain it. This can affect other components, requiring more time to maintain and reducing the device's practicality. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an exit cover with an adjustment mechanism.

[0005] This utility model is achieved by the following technical solution: an outdoor protective cover with an adjustment mechanism, including a hat strap, with adjustment components on both sides of the hat strap, a rotating frame on the surface of the adjustment components, a limit groove on the surface of the rotating frame, and a protective cover fixedly connected to the left end of the rotating frame;

[0006] The adjustment assembly includes a limiting frame, a connecting frame fixedly connected to the inner wall of the limiting frame, a fixed shaft fixedly connected to the inner wall of the connecting frame, a first spring sleeved on the surface of the fixed shaft, a sliding plate slidably connected to the surface of the fixed shaft, a pressure frame slidably connected to the inner wall of the connecting frame, a second spring clamped to the surface of the pressure frame, a limiting slide fixedly connected to the end of the pressure frame near the hood strap, a connecting plate slidably connected to the surface of the limiting slide, and a mounting frame fixedly connected to the end of the connecting plate away from the hood strap.

[0007] The above technical solution uses pressure frames on both sides to limit the angle of the protective cover and sliding plates on both sides to connect the rotating frame with the protective cover. This design allows for easy adjustment of the protective cover to a suitable position and convenient disassembly and assembly when the protective cover needs maintenance. This makes the subsequent use of the device more convenient and stable, and improves the overall practicality of the device.

[0008] As a further improvement to the above solution, the surface of the limiting slide is slidably connected to the inner wall of the mounting bracket, and the surface of the limiting slide is engaged with the inner wall of the limiting groove.

[0009] The above technical solution provides a limit for the rotation adjustment of the rotating frame and the protective cover, preventing the protective cover from loosening during use and making the device more convenient and stable to use.

[0010] As a further improvement to the above solution, the surface of the limiting frame is rotatably connected to the inner wall of the rotating frame, and the end of the limiting frame near the mounting frame is rotatably connected to the surface of the rotating frame.

[0011] The above technical solution provides stable support for the rotation of the rotating frame, prevents the rotating frame from deviating when it drives the protective cover to rotate, and improves the practicality of the device.

[0012] As a further improvement to the above solution, the end of the second spring near the connecting plate is fixedly connected to the inner wall of the mounting bracket, and both sides of the cap strap are fixedly connected to the surface of the connecting plate.

[0013] As a further improvement to the above solution, the surface of the sliding plate is slidably connected to the inner wall of the connecting frame.

[0014] As a further improvement to the above solution, the first spring is located at one end of the sliding plate near the center of the connecting frame.

[0015] The above technical solution provides the conditions for the automatic reset of the sliding plate, making the device more convenient to use.

[0016] As a further improvement to the above solution, the surface of the sliding plate engages with the inner wall of the mounting bracket.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes the principle of pressing the sliding plates on both sides to make them slide against the inner wall of the connecting frame, thereby allowing the ends of the sliding plates to contact the limiting position between the sliding plates and the mounting frame. Then, pulling the limiting frame causes the sliding plates and other parts to detach from the mounting frame, thus releasing the limiting position between the limiting frame and the mounting frame and the rotating frame. After both limiting frames have detached, the cap strap can be pressed to deform it, allowing the rotating frame and protective cover to be removed for maintenance. After maintenance, the rotating frame and protective cover are returned to their original positions, and the sliding plates are pressed again to slide towards the center of the connecting frame and insert back into the mounting frame. After the sliding plates return to their original position, the pressure on the sliding plates is released, and the sliding plates rebound under the action of the first spring, thus locking back into the mounting frame and reinstalling the limiting frame to limit the rotating frame. This facilitates convenient disassembly and maintenance of the protective cover.

[0019] This invention uses the pressure frames on both sides to cause the limiting slide to retract a certain distance into the connecting plate, thereby lifting the part of the limiting slide that protrudes from the mounting frame and separates it from the inner wall of the limiting groove, thus limiting the rotation of the rotating frame. At this time, the angle of the rotating frame and the protective cover can be adjusted for better use of the device. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5 This embodiment of an exterior protective cover with an adjustment mechanism includes a hat strap 1, adjustment components 2 are provided on both sides of the hat strap 1, a rotating frame 3 is provided on the surface of the adjustment component 2, a limit groove 4 is provided on the surface of the rotating frame 3, and a protective cover 5 is fixedly connected to the left end of the rotating frame 3.

[0030] Adjustment assembly 2 includes a limiting frame 201, a connecting frame 202 fixedly connected to the inner wall of the limiting frame 201, a fixed shaft 203 fixedly connected to the inner wall of the connecting frame 202, a first spring 204 sleeved on the surface of the fixed shaft 203, a sliding plate 205 slidably connected to the surface of the fixed shaft 203, a pressure frame 206 slidably connected to the inner wall of the connecting frame 202, a second spring 207 clamped on the surface of the pressure frame 206, and a limiting slide 208 fixedly connected to one end of the pressure frame 206 near the cap strap 1. The surface of the device is slidably connected to a connecting plate 209. The end of the connecting plate 209 away from the cap strap 1 is fixedly connected to a mounting bracket 210. The angle of the protective cover 5 is limited by pressing the pressure brackets 206 on both sides, and the rotating bracket 3 is connected to the protective cover 5 by squeezing the sliding clamps 205 on both sides. This design achieves the ability to easily adjust the protective cover 5 to a suitable position, and also allows for easy disassembly and assembly when the protective cover 5 needs maintenance. This makes the subsequent use of the device more convenient and stable, and improves the overall practicality of the device.

[0031] The surface of the limiting slide 208 is slidably connected to the inner wall of the mounting bracket 210, and the surface of the limiting slide 208 is engaged with the inner wall of the limiting groove 4.

[0032] The surface of the limiting frame 201 is rotatably connected to the inner wall of the rotating frame 3, and the end of the limiting frame 201 near the mounting frame 210 is rotatably connected to the surface of the rotating frame 3. This structure provides a limit for the rotation adjustment of the rotating frame and the protective cover, preventing the protective cover from loosening during use, and making the use of the device more convenient and stable.

[0033] The second spring 207 is fixedly connected to the inner wall of the mounting bracket 210 at one end near the connecting plate 209, and the two sides of the cap strap 1 are fixedly connected to the surface of the connecting plate 209.

[0034] The surface of the sliding plate 205 is slidably connected to the inner wall of the connecting frame 202.

[0035] The first spring 204 is located at one end of the sliding plate 205 near the center of the connecting frame 202.

[0036] The surface of the sliding plate 205 engages with the inner wall of the mounting bracket 210.

[0037] The implementation principle of an adjustable door cover in this application embodiment is as follows: When using the cover, first, the entire device is brought to the head using the headband 1. Then, the pressure brackets 206 on both sides are pressed to drive the limiting slide 208 to retract a certain distance into the connecting plate 209. This lifts the portion of the limiting slide 208 protruding from the mounting bracket 210 and separates it from the inner wall of the limiting groove 4, thereby contacting the rotation limit of the rotating frame 3. At this time, the angle of the rotating frame 3 and the cover 5 can be adjusted for better use of the device. When the cover 5 needs maintenance, the sliding plates 205 on both sides are squeezed to slide on the inner wall of the connecting bracket 202, so that the end of the sliding plate 205 contacts the limit between the mounting bracket 210. Then, the limiting bracket 201 is pulled to disengage the sliding plate 205 and other parts from the mounting bracket 210, thereby releasing the limit between the limiting bracket 201 and the mounting bracket 210 on the rotating frame 3. After both limiting brackets 201 are disengaged, the headband 1 can be squeezed to... The rotating frame 3, along with the protective cover 5, is removed for maintenance due to deformation. After maintenance, the rotating frame 3 and the protective cover 5 are put back in, and the sliding plate 205 is pressed again to slide towards the center of the connecting frame 202 and insert it back into the mounting frame 210. After the sliding plate 205 is reset, the pressure on the sliding plate 205 is released. At this time, the sliding plate 205 rebounds under the action of the first spring 204, thereby locking itself back into the mounting frame 210, thus reinstalling the limiting frame 201 into the mounting frame 210 and limiting the rotating frame 3. This completes the disassembly and maintenance of the protective cover 5. The design of using the pressure frames 206 on both sides to limit the angle of the protective cover 5 and using the sliding plates 205 on both sides to connect the rotating frame 3 and the protective cover 5 achieves the density of easy adjustment of the protective cover 5 to a suitable position and easy disassembly and assembly when the protective cover 5 needs maintenance, making the subsequent use of the device more convenient and stable, and improving the overall practicality of the device.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
