Description

Technical Field

[0001] This utility model relates to the field of fire safety equipment technology, and specifically discloses a fire helmet that facilitates the installation and disassembly of a searchlight. Background Technology

[0002] Fire helmets are widely used in various firefighting scenarios, such as urban fire rescue, forest fire fighting, chemical accident handling, and earthquake relief. In these scenarios, firefighters need to quickly and accurately determine the location of the fire source and the situation of trapped personnel. Searchlights, which are easy to install and remove, provide reliable lighting support, helping to improve work efficiency and rescue success rates.

[0003] Chinese patent CN212938195U2 discloses a fire helmet that facilitates the installation of a searchlight. The helmet includes a helmet body and a protrusion. The helmet body has a helmet opening at its bottom, a cape attached to one side, and a helmet visor attached to the top. A limiting groove is formed on the side of the helmet visor near a first sliding groove, and a goggle is connected to the side of the baffle near the limiting groove. A fourth sliding groove is formed at one end of a fixing rod, and a second spring is connected to one side of the fourth sliding groove. The protrusion is connected to one end of the second spring. This fire helmet, which facilitates the installation of a searchlight, is equipped with a rotating block and a clamping plate. When the searchlight is pulled up and down by hand, and the applied force exceeds the friction between the rotating block and the clamping plate, the rotating block will rotate via a support frame. When the searchlight is adjusted to a suitable angle, the force is released, fixing the searchlight's position and completing the adjustment of the searchlight's illumination angle.

[0004] The aforementioned device is inconvenient to disassemble after the searchlight is installed, resulting in complicated installation and removal, low work efficiency, inability to repair or replace the searchlight in a timely manner when it is damaged, and limited adjustable range, making it impractical. Therefore, a fire helmet that facilitates the installation and removal of searchlights is needed to solve this problem. Utility Model Content

The searchlights are easy and quick to install and remove, making it convenient to repair and replace them, thus increasing work efficiency. The direction and angle of the searchlights can be easily adjusted with a wider range of adjustment, making it highly practical.

[0006] This utility model is implemented as follows: a fire helmet that facilitates the installation and disassembly of a searchlight includes a fire helmet body and a searchlight body. A fixing block is fixedly connected to the right end face of the fire helmet body. An adjustment mechanism is provided on the right side of the fixing block. The adjustment mechanism includes a first damping shaft fixedly connected to the right end face of the fixing block. A C-shaped frame is rotatably connected to the right end face of the first damping shaft. A second damping shaft is rotatably connected inside the C-shaped frame. A connecting plate is fixedly connected to the outer wall of the second damping shaft. A mounting plate is fixedly connected to the right end face of the connecting plate.

[0007] The upper surface of the mounting plate is provided with a mounting groove, and a mounting block is provided inside the mounting groove. A fixing plate that abuts against the right end surface of the mounting plate is fixedly connected to the right end surface of the mounting block. The searchlight body is installed on the right end surface of the fixing plate.

[0008] The mounting plate has two symmetrically distributed locking mechanisms inside. Each locking mechanism includes a placement groove formed on the inner side wall of the mounting slot. A locking block is slidably connected inside the placement groove. A spring is provided between the locking block and the inner side wall of the placement groove. The front and rear end faces of the mounting block are each provided with a corresponding locking groove.

[0009] As a preferred embodiment of the present invention, a fire helmet for easy installation and disassembly of a searchlight, the end of the locking block away from the mounting groove is fixedly connected to a connecting rod, and the other end of the connecting rod passes through the mounting plate and is slidably connected to the mounting plate.

[0010] As a preferred embodiment of the present invention, which facilitates the installation and disassembly of a searchlight in a fire helmet, the end of the locking block near the mounting block is configured as an inclined surface.

[0011] As a preferred embodiment of the present invention, a fire helmet that facilitates the installation and disassembly of a searchlight, the left end face of the mounting block is fixedly connected to a baffle that abuts against the left end of the mounting plate.

[0012] As a preferred embodiment of this utility model of a fire helmet that facilitates the installation and disassembly of a searchlight, the right end face of the mounting plate is fixedly connected with two symmetrically distributed limiting strips, and the left end face of the fixing plate is provided with two limiting grooves that match the limiting strips.

[0014] As a preferred embodiment of the present invention, which facilitates the installation and disassembly of a searchlight, the other end of the connecting rod extends to the outside of the mounting plate and is fixedly connected with a pull ring.

[0015] The beneficial effects of this utility model are:

[0016] (1) This fire helmet that facilitates the installation and disassembly of searchlights uses the lower end face of the mounting block to press the locking block, allowing the locking block to fully enter the interior of the mounting groove. At the same time, the spring is compressed. When the lower end face of the mounting block abuts against the bottom surface of the mounting groove, the mounting groove and the locking groove are aligned. At this time, the locking block is pressed into the interior of the locking groove by the spring, and the mounting block is locked in place. The connecting rod is pulled by the pull ring, causing the connecting rod to move the locking block out of the interior of the locking groove. Then the mounting block is moved upward, which in turn moves the baffle, the fixing plate and the searchlight body, making it easier to disassemble the searchlight body. This increases work efficiency and facilitates the maintenance and replacement of the searchlight.

[0017] (2) This fire helmet, which is easy to install and disassemble, can rotate the C-frame, the second damping shaft, the connecting plate and the mounting plate through the first damping shaft, and can flip the connecting plate, the mounting plate and the clamping mechanism up and down through the second damping shaft, thereby changing the direction and angle of the searchlight body, with a wider adjustment range and strong practicality.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-4 A fire helmet for easy installation and disassembly of a searchlight includes a fire helmet body 1 and a searchlight body 11. A fixing block 2 is fixedly connected to the right end face of the fire helmet body 1. An adjustment mechanism is provided on the right side of the fixing block 2. The adjustment mechanism includes a first damping shaft 3 fixedly connected to the right end face of the fixing block 2. A C-shaped frame 4 is rotatably connected to the right end face of the first damping shaft 3. A second damping shaft 5 is rotatably connected inside the C-shaped frame 4. A connecting plate 6 is fixedly connected to the outer wall of the second damping shaft 5. A mounting plate 7 is fixedly connected to the right end face of the connecting plate 6.

[0026] The upper surface of the mounting plate 7 is provided with a mounting groove 8, and a mounting block 9 is provided inside the mounting groove 8. A fixing plate 10 that abuts against the right end of the mounting plate 7 is fixedly connected to the right end of the mounting block 9. The searchlight body 11 is installed on the right end of the fixing plate 10.

[0027] The mounting plate 7 has two symmetrically distributed clamping mechanisms inside. The clamping mechanism includes a placement groove 15 opened in the inner side wall of the mounting groove 8. A clamping block 16 is slidably connected inside the placement groove 15. A spring 17 is provided between the clamping block 16 and the inner side wall of the placement groove 15. The front and rear end faces of the mounting block 9 are provided with corresponding clamping grooves 18.

[0028] In this embodiment: During use, the mounting block 9 is inserted into the mounting groove 8. The lower end face of the mounting block 9 presses the locking block 16, causing the locking block 16 to fully enter the interior of the placement groove 15. At the same time, the spring 17 is compressed. When the lower end face of the mounting block 9 abuts against the inner bottom surface of the mounting groove 8, the placement groove 15 and the locking groove 18 are aligned. At this time, the spring 17 presses the locking block 16 into the interior of the locking groove 18, thus fixing the mounting block 9. This makes it easier to fix the fixing plate 10 and the searchlight body 11, making the operation simpler and facilitating the maintenance and replacement of the searchlight.

[0029] The first damping shaft 3 allows the C-frame 4, the second damping shaft 5, the connecting plate 6, and the mounting plate 7 to rotate. The second damping shaft 5 allows the connecting plate 6, the mounting plate 7, and the clamping mechanism to flip up and down, thereby changing the direction and angle of the searchlight body 11. This provides a wider adjustment range and greater practicality.

[0030] As a technical optimization of this utility model, the end of the card block 16 away from the mounting groove 8 is fixedly connected to a connecting rod 19, and the other end of the connecting rod 19 passes through the mounting plate 7 and is slidably connected to the mounting plate 7.

[0031] In this embodiment: the connecting rod 19 facilitates the movement of the locking block 16, allowing the locking block 16 to enter the interior of the placement groove 15.

[0032] As a technical optimization of this utility model, the end of the card block 16 near the mounting block 9 is set as an inclined surface.

[0033] In this embodiment: Since the end of the card block 16 near the mounting block 9 is set as an inclined surface, it is convenient to squeeze the card block 16.

[0034] As a technical optimization of this utility model, a baffle 12 that abuts against the left end of the mounting plate 7 is fixedly connected to the left end face of the mounting block 9.

[0035] In this embodiment: the left end of the baffle 12 and the mounting plate 7 abut against each other, thereby limiting the mounting block 9 in the left and right directions and making the mounting block 9 more stable.

[0036] As a technical optimization of this utility model, two symmetrically distributed limiting strips 14 are fixedly connected to the right end face of the mounting plate 7, and two limiting grooves 13 matching the limiting strips 14 are opened on the left end face of the fixing plate 10.

[0037] In this embodiment: the limiting strip 14 is slidably connected inside the limiting groove 13 to limit the mounting block 9 in the front and back directions, making the mounting block 9 more stable.

[0038] As a technical optimization of this utility model, the left and right end faces of the card block 16 are fixedly connected to limit posts, and the left and right inner walls of the mounting groove 15 are provided with sliding grooves that match the limit posts.

[0039] In this embodiment: the locking block 16 drives the limiting post to slide inside the slide groove, making the movement of the locking block 16 more stable.

[0040] As a technical optimization of this utility model, the other end of the connecting rod 19 extends to the outside of the mounting plate 7 and is fixedly connected with a pull ring 20.

[0041] In this embodiment, the connecting rod 19 can be easily pulled by the pull ring 20.

[0042] The working principle and usage process of this utility model are as follows: When in use, the mounting block 9 is inserted into the interior of the mounting groove 8. The lower end face of the mounting block 9 presses the locking block 16, causing the locking block 16 to fully enter the interior of the placement groove 15. At the same time, the spring 17 is pressed. When the lower end face of the mounting block 9 abuts against the inner bottom surface of the mounting groove 8, the placement groove 15 and the locking groove 18 are aligned. At this time, the spring 17 presses the locking block 16 into the interior of the locking groove 18, thus fixing the mounting block 9. This makes it easier to fix the fixing plate 10 and the searchlight body 11, and the operation is simpler.

[0043] When disassembly is required, pull the two connecting rods 19 by pulling the two pull rings 20 respectively, so that the two connecting rods 19 drive the two locking blocks 16 to move backward, so that the two locking blocks 16 enter the interior of the mounting groove 15 and disengage from the interior of the locking groove 18. Then, move the mounting block 9 upward, which in turn moves the baffle 12, the fixing plate 10 and the searchlight body 11, thereby facilitating the disassembly of the searchlight body 11, improving work efficiency and making it easier to repair and replace the searchlight.

[0044] The first damping shaft 3 allows the C-frame 4, the second damping shaft 5, the connecting plate 6, and the mounting plate 7 to rotate. The second damping shaft 5 allows the connecting plate 6, the mounting plate 7, and the clamping mechanism to flip up and down, thereby changing the direction and angle of the searchlight body 11. This provides a wider adjustment range and greater practicality.
