DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] Embodiment 1: A portable headlamp for outdoor use, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it includes a headband 1, the front part of the headband 1 is provided with an opening, the end of the headband 1 at the opening is made of plastic material, the middle part of the headband is an elastic bandage, a connecting piece 12 is slidably connected between the left and right sides of the front part of the headband 1, a searchlight 11 is installed in the middle of the connecting piece 12, four telescopic rods 112 uniformly distributed along the circumferential direction are fixedly connected to the front side of the connecting piece 12, a fixing piece 13 is fixedly connected between the telescopic parts of the four telescopic rods 112, and a force storage spring 111 is connected between the fixing piece 13 and the fixed parts of the four telescopic rods 112. The four force storage springs 111 are respectively wound around the telescopic parts of the adjacent telescopic rods 112, and blocking plates 110 are rotatably connected to the left and right sides of the fixing piece 13, a gear 19 is fixedly connected to the middle part of each blocking plate 110, and a moving component for driving the blocking plate 110 to open or close is provided on the top of the connecting piece 12.

[0036] like Figure 3 As shown, the moving assembly includes a connecting rod 14, which is fixedly connected to the top of the connecting member 12. A sliding frame 17 is slidably connected to the connecting rod 14. A pressure spring 15 is fixedly connected between the sliding frame 17 and the connecting member 12. The pressure spring 15 is wound around the connecting rod 14. Two pull ropes 16 are fixedly connected to the sliding frame 17. The pull ropes 16 are used to drive the sliding frame 17 to move. The movable ends of the two pull ropes 16 are respectively fixedly connected to one side of the headband 1 close to the connecting member 12. The headband 1 is used to drive the pull ropes 16 to tighten and contract. The bottom of the sliding frame 17 is fixedly connected to symmetrically distributed racks 18, and the two racks 18 are respectively meshed with adjacent gears 19.

[0037] When the user is not wearing the device, the open end of the front part of the headband 1 will be located inside the connecting piece 12, the drawstring 16 will be in a relaxed state, the sliding frame 17 will be located at the front end of the connecting rod 14, and the blocking plate 110 will cover the front side of the searchlight 11. When the device is used, the headband 1 is first pulled to make the headband 1 slide outward from the inside of the connecting piece 12, driving the drawstrings 16 on the left and right sides of the headband 1 to be pulled outward, thereby driving the sliding frame 17 to move backward. At this time, the pressure spring 15 is compressed, and the sliding frame 17 moves backward, driving the rack 18 to move backward. When the rack 18 moves backward, it will mesh with the gear 19 to rotate the gear 19. The rotation of the gear 19 drives the blocking plate 110 to flip outward and open, so that the blocking plate 110 automatically disengages from the obstruction of the front side of the searchlight 11, which is convenient for the searchlight 11 to illuminate.

[0038] When the device is accidentally knocked off the user's head and falls to the ground, the headband 1 contracts and the drawstring 16 is in a relaxed state. At the same time, under the elastic force of the pressure spring 15, the sliding frame 17 drives the rack 18 to move forward and reset, and the rack 18 and the gear 19 engage again, thereby driving the blocking plate 110 to rotate inward and close, thereby covering the front side of the searchlight 11 for protection.

[0039] When the device falls to the ground, the fixing part 13 collides with the ground, and the fixing part 13 is squeezed by the force so that the telescopic parts of the four telescopic rods 112 shrink inwardly, and the force storage spring 111 is deformed. Under the action of the force storage spring 111, the impact force received by the fixing part 13 is buffered, thereby buffering the impact force received by the searchlight 11 around. In summary, when the user is not wearing the device, the blocking plate 110, the fixing part 13, and the telescopic rod 112 cooperate with each other to protect the front side and the surrounding of the searchlight 11. During the wearing process, the headband 1 is stretched to drive the blocking plate 110 to flip outward and open, thereby removing the obstruction to the front side of the searchlight 11 and facilitating the lighting of the searchlight 11. When the device accidentally falls off the user's head and falls to the ground, the sliding frame 17 is driven to move by sliding the headband 1, thereby driving the blocking plate 110 to flip inward and close, so as to protect the front side of the searchlight 11.

[0040] Embodiment 2: Based on embodiment 1, Figure 5 and Figure 6 As shown, it also includes a protective mechanism for facilitating rolling and protection when the device falls to the ground. The protective mechanism is arranged on the symmetrically distributed blocking plates 110. The protective mechanism includes sleeves 2. The symmetrically distributed sleeves 2 are respectively fixed to the blocking plates 110. Four sleeves 2 are threadedly connected with screw rods 21. The four screw rods 21 are fixedly connected to the sides away from each other on the four screw rods 21. Support columns 23 are fixedly connected to the front and rear sides of each connecting plate 22. Rolling balls are arranged in the eight support columns 23. Four symmetrically distributed guide rods 24 are fixedly connected to the front side of the connecting member 12. The connecting plate 22 is slidably connected to the adjacent guide rods 24.

[0041] According to the previous steps, when the blocking plate 110 flips inward or outward, it will drive the sleeve 2 to rotate forward or reverse, thereby driving the screw 21 to move inward or outward, and further driving the connecting plate 22 and the support column 23 to move inward or outward. When the searchlight 11 falls to the ground, the connecting plate 22 and the support column 23 move outward to support the fixing part 13 and the searchlight 11 around, avoiding the searchlight 11 and the fixing part 13 from directly contacting the ground. When the ball on the support column 23 touches the ground, it rolls to reduce the friction between the searchlight 11 and the fixing part 13 and the ground, further reducing the damage to the device after falling.

[0042] like Figure 7 , Figure 8 and Fig. 9As shown, it also includes a switching mechanism for removing the obstruction of the front side of the searchlight by the blocking plate 110 and facilitating the handheld searchlight to illuminate. The switching mechanism is arranged at the bottom of the connecting member 12. The switching mechanism includes a connecting frame 3, and the connecting frame 3 is fixedly connected between the two racks 18. The left and right ends of the front part of the headband 1 are fixedly connected with sliding plates 37. Drawstrings 38 are connected between the two sliding plates 37 and the connecting frame 3. The drawstrings 38 can drive the sliding plates 37 to move. The fixed block 32 is fixedly connected to the bottom of the connecting member 12. The bottom of the fixed block 32 is fixedly connected to a fixed column 33. The lower end of the fixed block 32 is fixedly connected to a slider 36. Another slider 36 is slidably connected to the fixed column 33. Two folding connecting rods 31 are rotatably connected between the two sliders 36. The two folding connecting rods 31 are slidably connected to the adjacent sliding plates 37. A fixing component is provided at the bottom of the fixed column 33.

[0043] like Figure 7 As shown, the fixing assembly includes a thin rope 34, which is fixed to the bottom of the fixing column 33, and a pin 35 is fixed to the movable end of the thin rope 34. A plug hole is provided on the lower slider 36, and evenly distributed circular holes are also provided on the fixing column 33. The pin 35 slides in the plug hole, and the pin 35 also slides in the evenly distributed circular holes.

[0044] When the searchlight 11 is removed and hand-held for lighting, the latch 35 is pulled out, the two folding links 31 are in a folded state, and the two blocking plates 110 are flipped inward to cover the front side of the searchlight 11. At this time, the slider 36 on the fixed column 33 can be pushed upward to drive the two folding links 31 to extend and move away from each other, thereby driving the sliding plate 37 to move away from each other, and the connecting frame 3 is driven to move backward through the two drawstrings 38. Under the action of the connecting frame 3, the two racks 18 move backward and engage with the adjacent gears 19, thereby driving the symmetrically distributed blocking plates 110 to flip outward and open, so that the two blocking plates 110 cancel the coverage of the front side of the searchlight 11. At this time, the latch 35 can be inserted into the circular hole of the fixed column 33 through the insertion hole of the slider 36 on the fixed column 33, so as to fix the slider 36 on the fixed column 33, thereby keeping the blocking plates 110 flipped outward and opened, which is convenient for lighting when hand-held.

[0045] like Fig.10 and Fig.11 As shown, it also includes a buffer mechanism for buffering when the blocking plate 110 is hit. The buffer mechanism is arranged on the blocking plate 110, and the buffer mechanism includes telescopic columns 41. The symmetrically distributed telescopic columns 41 are respectively fixed on the blocking plate 110, and the telescopic parts of the four telescopic columns 41 are all fixed with blocking members 4. Linear springs 42 are fixed between the four blocking members 4 and the adjacent blocking plates 110. The four linear springs 42 are all wound on the adjacent telescopic columns 41, and the linear springs 42 have a buffering effect on the blocking plate 110.

[0046] When the device falls to the ground, the blocking plate 110 flips inward and closes to protect the front side of the searchlight 11. The blocking member 4 will first contact the ground and be squeezed with the ground. The blocking member 4 is squeezed and moves backward, causing the telescopic part of the telescopic column 41 to contract, and the linear spring 42 is deformed. Under the deformation action of the linear spring 42, the blocking member 4 will have a buffering effect, thereby having a buffering effect on the searchlight 11, thereby increasing the protection effect of the device and improving the service life of the device.

[0047] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
