Technical Field

[0001] This utility model relates to the field of electric helmet technology, specifically a multifunctional electric work helmet. Background Technology

[0002] In the field of electrical work, workers are typically required to wear helmets to protect their heads from accidental injuries.

[0003] However, the inner lining of existing power work helmets is easily contaminated by sweat and dust during prolonged wear, requiring regular cleaning and maintenance. The connection between the inner lining and the outer shell of some existing helmets is complex, typically using a clamping mechanism, making installation and disassembly cumbersome. This not only increases the workload and time cost for workers when replacing or cleaning the lining but also hinders quick maintenance or adjustments in emergency situations. Therefore, developing a multi-functional power work helmet that effectively solves these problems is of significant practical importance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multifunctional helmet for power work, which solves the problem that the connection structure between the inner liner and the outer shell of some existing helmets is relatively complex, and the installation and disassembly process is cumbersome. This not only increases the workload and time cost for workers when changing or cleaning the inner liner, but also makes it difficult to quickly maintain or adjust the helmet in emergency situations.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a multifunctional electric work helmet includes an outer shell and an inner liner unit installed inside it, and a fixing unit is provided at the connection between the outer shell and the inner liner unit;

[0032] This utility model discloses a multifunctional helmet for power work.

[0033] Example 1

[0034] According to the appendix Figure 1-4 As shown, it includes an outer shell 1 and an inner liner unit 2 installed inside it, and a fixing unit 3 is provided at the connection between the outer shell 1 and the inner liner unit 2.

[0035] Liner unit 2 includes:

[0036] Inner liner 21, with sliders 211 fixedly connected to both sides of the inner liner 21;

[0037] Connecting strap 22 is installed on top of inner liner seat 21;

[0038] Fixed unit 3 includes:

[0039] Mounting base 31 is fixedly connected to the inside two sides of the outer shell 1, and the two ends of the inner liner 21 are slidably connected inside the mounting base 31;

[0040] Limiting block 32 is located at the bottom of mounting base 31;

[0041] Ejector assembly 34 is disposed within mounting base 31 and is used to assist in the quick installation and removal of inner liner 21.

[0042] Furthermore, sliders 211 are fixedly connected to both ends of the inner liner 21, and the sliders 211 are slidably connected inside the mounting base 31.

[0043] Furthermore, a connecting block 212 is fixedly connected to the top of the inner liner 21, and a connecting strip 22 is wrapped around the connecting block 212.

[0044] Furthermore, the inner liner unit 2 also includes an adjustment component 23, which is disposed on the back of the inner liner seat 21. The adjustment component 23 is prior art and is used to adjust the wearing size of the safety helmet to suit different users.

[0045] Furthermore, the fixing unit 3 also includes:

[0046] Threaded rod 33 is threadedly connected to the side of the outer shell 1. One end of threaded rod 33 passes through the outer shell 1 and is threadedly connected to the slider 211.

[0047] Knob 35 is fixedly connected to the other end of threaded rod 33.

[0048] Furthermore, the limiting block 32 and the slider 211 move against each other, and one end of the limiting block 32 is sleeved on the threaded rod 33. It is slidably connected to the mounting base 31 through the sliders 211 on both sides of the inner liner seat 21. Moving the limiting block 32 causes the limiting block 32 to abut against the slider 211. Then, by tightening the threaded rod 33, the inner liner unit 2 can be firmly fixed on the outer shell 1, so that the inner liner unit 2 can be quickly and easily installed and removed from the outer shell 1, which greatly saves the time and effort of the staff and facilitates the cleaning, replacement or maintenance of the inner liner.

[0049] Example 2

[0050] According to the appendix Figure 1-4 As shown, it includes an outer shell 1 and an inner liner unit 2 installed inside it, and a fixing unit 3 is provided at the connection between the outer shell 1 and the inner liner unit 2.

[0051] Liner unit 2 includes:

[0052] Inner liner 21, with sliders 211 fixedly connected to both sides of the inner liner 21;

[0053] Connecting strap 22 is installed on top of inner liner seat 21;

[0054] Fixed unit 3 includes:

[0055] Mounting base 31 is fixedly connected to the inside two sides of the outer shell 1, and the two ends of the inner liner 21 are slidably connected inside the mounting base 31;

[0056] Limiting block 32 is located at the bottom of mounting base 31;

[0057] Ejector assembly 34 is disposed within mounting base 31 and is used to assist in the quick installation and removal of inner liner 21.

[0058] Furthermore, the ejector component 34 includes:

[0059] Movable block 341 is slidably connected within mounting base 31;

[0060] Spring 342, one end of which is fixedly connected to moving block 341 and the other end of which is fixedly connected to mounting base 31. During insertion, slider 211 will squeeze and push out moving block 341 in the ejector assembly 34, causing spring 342 to be compressed. During disassembly, spring 342 can squeeze moving block 341 to move, thereby squeezing out a part of slider 211 for easy disassembly.

[0061] Working principle:

[0062] First, align the sliders 211 at both ends of the inner liner 21 with the mounting base 31 and slide them into the mounting base 31. During insertion, the sliders 211 will press against the moving block 341 in the ejector assembly 34, thus compressing the spring 342.

[0063] Next, move the limiting block 32 so that it abuts against the bottom end of the slider 211, thereby restricting the movement of the slider 211 and ensuring a stable connection between the inner liner 21 and the outer shell 1. Then rotate the knob 35 to drive the threaded rod 33 to rotate, so that one end of the threaded rod 33 is gradually screwed into the slider 211 until the threaded rod 33 firmly fixes the slider 211 in the mounting base 31.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
