[0036] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0037] Please also read Figures 1 to 5 The combined explosive-searching helmet provided by the utility model is now described. The combined explosive-searching helmet comprises a helmet body 10, two slider modules 20 and a mask 30. The two sides of the helmet body 10 are provided with a slide rail module 11; the two slider modules 20 are respectively slidably matched with the two slide rail modules 11, and the slider module 20 has a rotating part 21 and a fastener 22, and the fastener 22 is used to fix the position of the slider module 20 on the slide rail module 11; the mask 30 comprises two support arms 31 and an explosion-proof shell 32 fixed between the two support arms 31, and the two support arms 31 are respectively connected to the two rotating parts 21.

[0038] Compared with the prior art, the combined explosive-searching helmet provided in this embodiment, when applied to an explosive-searching environment, can connect the mask 30 to the slider module 20, slide the slider module 20 into the slide rail module 11 and fix it through the fastener 22 to complete the installation of the mask 30; when applied to an ordinary environment, the fastener 22 is disassembled, and the slider module 20 is slid out of the slide rail module 11, and the mask 30 is detachable. The combined explosive-searching helmet of the utility model utilizes the slide rail assembly of the helmet itself, and realizes the installation of the mask 30 through two slider modules 20, which can improve the bulletproof effect of the helmet compared to the traditional installation by punching holes on the helmet; the mask 30 in the present application is convenient to disassemble and adjust through the slider module 20, and the position of the slider module 20 can be adjusted according to different usage scenarios, or it can be decided whether to disassemble the mask 30 according to different usage scenarios, which is more convenient and flexible to use.

[0039] In some embodiments, an improved implementation of the slider module 20 may be as follows: Figure 2 and Figure 4 See the structure shown. Figure 2 and Figure 4The slide rail module 11 has a slide 12 and a plurality of positioning holes 13 arranged in the slide 12; the slider module 20 also includes a sliding portion 23 and an abutment bar 24, the sliding portion 23 is rotatably connected to the rotating portion 21, and the sliding portion 23 is slidably connected to the slide 12; one end of the abutment bar 24 is fixed to the sliding portion 23, and the other end is provided with a clamping block 25; the fastener 22 is used to push the end of the abutment bar 24 so that the clamping block 25 on the abutment bar 24 is clamped and matched with the corresponding positioning hole 13. During actual installation, the sliding slider module 20 can be slid according to the size of the mask 30 to drive the mask 30 to move forward and backward. When the sliding slider module 20 needs to be slid, the fastener 22 is separated from the abutment strip 24. Since one end of the abutment strip 24 is fixed to the sliding part 23, the other end will fit on the side of the sliding part 23 facing the helmet body 10 under its own elasticity, so that the clamping block 25 is separated from the positioning hole 13, and the position of the sliding part 23 in the slideway 12 can be freely slid to adjust the position; after the adjustment is completed, the fastener 22 is screwed, and the fastener 22 abuts against one end of the abutment strip 24 where the clamping block 25 is set, pushing the clamping block 25 to move toward the positioning hole 13. At this time, the abutment strip 24 is bent until the clamping block 25 is clamped with the positioning hole 13, and the rotation of the fastener 22 is stopped to complete the fixation of the slider module 20.

[0040] The abutting strip 24 in this structure has a certain elasticity, and the matching state between the clamping block 25 and the positioning hole 13 can be conveniently switched through the fastener 22, which is convenient for operation.

[0041] Optionally, the fastener 22 is a screw, and the fastener 22 is connected to the sliding portion 23 . By screwing the fastener 22 , the end of the fastener 22 can abut against the end of the abutting strip 24 , thereby pushing the clamping block 25 to move toward the positioning hole 13 .

[0042] In some embodiments, an improved implementation of the sliding portion 23 may be as follows: Figure 1 , Figure 4 and Figure 5 See the structure shown. Figure 1 , Figure 4 and Figure 5 The sliding portion 23 is provided with a groove 26 on the side facing the helmet body 10, and the abutting strip 24 is located in the groove 26. The extending direction of the groove 26 is parallel to the extending direction of the abutting strip 24. When the end of the abutting strip 24 provided with the clamping block 25 moves in the direction of approaching or moving away from the positioning hole 13, it is always kept in the groove 26, but the clamping block 25 will protrude from the groove 26 and clamp the positioning hole 13. The groove 26 plays a role of limiting the abutting strip 24, thereby improving the matching accuracy of the clamping block 25 and the positioning hole 13.

[0043] In some embodiments, an improved embodiment of the above-mentioned abutment strip 24 can be adopted as follows Figures 2 to 3 See the structure shown. Figures 2 to 3The abutting strip 24 is also provided with a bending portion 27, which is located at one end of the abutting strip 24 close to the clamping block 25 and is bent in a direction away from the helmet body 10, and is used to abut the side wall of the sliding portion 23. The length of the bending portion 27 is greater than the moving stroke of the abutting strip 24 and one end of the clamping block 25, so that when the fastener 22 pushes the end of the abutting strip 24 to move close to or away from the positioning hole 13, a guiding function can be achieved.

[0044] It should be noted that the abutment strip 24 and the groove 26 can be provided selectively or simultaneously. When they are provided simultaneously, the guiding effect of the abutment strip 24 is better, and the matching accuracy of the clamping block 25 and the positioning hole 13 is further improved.

[0045] In some embodiments, an improved implementation of the sliding portion 23 may be as follows: Figures 2 to 3 See the structure shown. Figures 2 to 3 The side of the sliding part 23 facing away from the helmet body 10 is provided with a plurality of ribs 28. By providing the ribs 28, the structural strength of the sliding part 23 can be increased, and when the sliding part 23 is pushed to move in the slideway 12, the position of the ribs 28 can be moved, which makes the operation more convenient and avoids slipping.

[0046] In some embodiments, an improved implementation of the rotating part 21 can be as follows: Figure 2 , Figure 3 and Figure 5 See the structure shown. Figure 2 , Figure 3 and Figure 5 A side wall of the rotating part 21 away from the support arm 31 is provided with a limit plate 29. Since the support arm 31 needs to be installed on the rotating part 21, the limit plate 29 is provided on the rotating part 21, which can facilitate the positioning of the support arm 31, reduce the difficulty of assembly, and shorten the assembly time.

[0047] In some embodiments, a specific connection method between the support arm 31 and the rotating part 21 can be as follows: Figures 2 to 4 See the structure shown. Figures 2 to 4 A rotating shaft 33 is connected between each arm 31 and the corresponding rotating part 21. The rotating part 21 is provided with a plurality of adjustment holes 210, and the plurality of adjustment holes 210 are located at the periphery of the rotating shaft 33. A positioning assembly 40 is also provided on the arm 31, and the positioning assembly 40 has a plug-in portion for plugging and matching with different adjustment holes 210 to adjust the opening and closing angle of the mask 30. For example, there are three adjustment holes 210, and the three adjustment holes 210 correspond to three gears respectively: one is that the mask 30 is located in the front, one is that the mask 30 is opened and closed 45 degrees upward, and one is that the mask 30 is located at the top of the helmet body 10.

[0048] When in use, the mask 30 can be adjusted to different postures by cooperating with the plug-in part and different adjustment holes 210, which is convenient for use; the mask 30 can be opened and closed at various angles and the slider module 20 can slide on the slide rail module 11 to adjust the position of the mask 30, so that the mask 30 can be adjusted to more postures and applied to more scenarios.

[0049] In some embodiments, a specific implementation of the positioning assembly 40 can be as follows: Figure 1 See the structure shown. Figure 1 The arm 31 is provided with a through hole, and the positioning assembly 40 includes a nut 41 and a bolt 42. The nut 41 is fixed to the arm 31, and the middle hole of the nut 41 is coaxial with the through hole; the bolt 42 is screwed to the nut 41, and the bolt 42 forms a plug-in portion. When the mask 30 is rotated and adjusted, the head of the bolt 42 does not protrude from the side of the arm 31 facing the rotating portion 21. After the mask 30 is rotated and adjusted, the bolt 42 can be screwed, and the bolt 42 passes through the through hole and plugs into the corresponding adjustment hole 210. At this time, the mask 30 cannot continue to rotate, and its posture is fixed.

[0050] Specifically, a knob 43 is fixedly connected to the outer periphery of the bolt 42, and an anti-skid pattern is arranged on the outer periphery of the knob 43. The bolt 42 is rotated by turning the knob 43, and since the anti-skid pattern is arranged on the knob 43, the bolt 42 can be rotated conveniently and the adjustment is fast.

[0051] In some embodiments, a specific connection method between the explosion-proof shell 32 and the support arm 31 can be as follows: Figure 1 See the structure shown. Figure 1 The explosion-proof shell 32 is detachably connected to the support arm 31. The detachable method can be connected by threaded connectors, magnetic suction, adhesive bonding, etc., which is convenient for replacing the explosion-proof shell 32. The explosion-proof shell 32 of different thicknesses can be replaced according to different usage scenarios.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
