As shown in fig. 1, the invention provides an industrial lighting head lamp 10 with semiconductor light emitting diodes, which comprises a lamp body 11 and a head hoop 12, wherein an installation seat 13 is arranged on the head hoop 12, and the lamp body 11 is detachably connected with the installation seat 13 through a clamping device 20. As shown in fig. 2, the clamping device 20 includes: the lamp comprises a clamping seat 100, a clamping piece 200 and a movable lock disc 300, wherein the clamping seat 100 is fixedly arranged on a lamp body 11, the clamping piece 200 is fixedly arranged on a mounting seat 13, and the movable lock disc 300 is slidably arranged on the clamping piece 200. As shown in fig. 3, the clamping seat 100 is provided with a clamping blade 110, the clamping piece 200 is provided with a clamping claw 210, the clamping claw 210 is provided with a containing groove 220 matched with the clamping blade 110, two sides of the containing groove 220 are opened, the clamping blade 110 is contained in or separated from the containing groove 220, the movable lock plate 300 is provided with a limit stop block 310, and the limit stop block 310 is used for stopping two sides of the containing groove 220. The lamp body 11 is internally provided with a semiconductor light-emitting diode, has simple structure and small volume, is suitable for the working environment with small current (20-200 milliamperes), namely has small power consumption, is convenient to use and has low cost.

In this embodiment, as shown in fig. 3, the clamping member 200 is provided with a guiding rod 230, and the movable lock plate 300 is slidably disposed on the guiding rod 230 through a telescopic elastic member 320. The telescopic elastic member 320 has a spring structure, the telescopic elastic member 320 is sleeved on the guide rod 230, the guide rod 230 is provided with a collar 231, one end of the telescopic elastic member 320 is pressed against the collar 231, and the other end is pressed against the movable lock plate 300.

In the present embodiment, as shown in fig. 3, the number of the holding claws 210 is plural, the plural holding claws 210 are distributed in an annular array with the axis of the guide rod 230 as the center, and the number of the holding blades 110 matches the number of the holding claws 210. A jaw gap 240 is formed between two adjacent clamping jaws 210, the size of the clamping blade 110 is smaller than or equal to the size of the jaw gap 240, and the limiting blocking block 310 is slidably arranged in the jaw gap 240.

Under the condition of no external force, the telescopic elastic member 320 pushes the movable lock collar 300 toward the clamping member 200, so that the movable lock collar 300 is propped against the clamping claw 210, at this time, the limiting blocking block 310 is located in the claw gap 240, and both sides of the accommodating groove 220 are blocked by the limiting blocking block 310. When in use, a user wears the head band 12 on the head, and then corresponds the clamping seat 100 of the lamp body 11 to the clamping piece 200, namely, the clamping blades 110 on the clamping seat 100 correspond to the clamping jaw gaps 240, as shown in fig. 4; then, the holding blade 110 is pushed into the jaw gap 240, at this time, the holding blade 110 will abut against and push the limit stopper 310, so that the receiving groove 220 is exposed; next, the user rotates the clamping seat 100 to enable the clamping blade 110 to enter the accommodating groove 220, at this time, the limiting stop block 310 is not supported by the clamping blade 110 any more, and under the action of the telescopic elastic piece 320, the limiting stop block 310 plugs two sides of the accommodating groove 220 again, so that the clamping blade 110 cannot be separated from the accommodating groove 220, and the clamping seat 100 and the clamping piece 200 are stably connected together, namely, the lamp body 11 is mounted on the mounting seat 13;

when the lock is disassembled, a user only needs to overcome the elastic force of the telescopic elastic piece 320 to push the movable lock plate 300 to a direction away from the clamping claw 210, so that the limit stop block 310 can be far away from the accommodating groove 220; then, the user rotates the clamping seat 100 to make the clamping blade 110 rotate out of the accommodating groove 220, so that the clamping seat 100 can be smoothly separated from the clamping piece 200.

Therefore, the lamp body 11 and the mounting seat 13 of the present invention are not connected by the conventional opening elastic buckle, but are connected by the clamping connection manner of the clamping seat 100 and the clamping piece 200. After the clamping manner is adopted, the clamping seat 100 cannot be separated from the clamping piece 200 by itself, so that the lamp body 11 is prevented from falling off in the use process while the assembly and the disassembly are convenient, and the service life of the mounting seat 13 is prolonged.

Further, in consideration of the need of the user to first make the clamping blade 110 and the jaw gap 240 correspond to each other before installation, but it is difficult to make the two correspond to each other under the condition of insufficient light, in order to facilitate the operation of the user, the present invention improves the limiting block 310 and the clamping blade 110 so that the two can attract each other.

Specifically, in the present embodiment, permanent magnets (not shown) are disposed on the end of the limit stop 310 and the retaining blade 110, and the permanent magnets are used to make the limit stop 310 and the retaining blade 110 attract each other. With the help of the permanent magnet, when the clamping blade 110 approaches the limit stop block 310, the magnetic attraction force can guide the clamping blade 110 to rotate to a relatively fitting angle, so that the clamping blade 110 and the limit stop block 310 automatically correspond to each other, and the operation is convenient for a user. Preferably, the permanent magnet may adopt the principle of attraction between two opposite poles, for example, the permanent magnet on the limit stop 310 is N pole, and the permanent magnet on the clamping blade 110 is S pole. Of course, one of the limit stopper 310 and the holding blade 110 may be made of iron, and the other may be provided with a permanent magnet, so that the two may attract each other.

Further, after the clip socket 100 is connected to the clip member 200, the two sides of the clip blade 110 are blocked by the limiting stoppers 310, so that the clip blade 110 cannot be separated from the accommodating groove 220, but the clip blade 110 is not limited in the axial direction, and therefore the lamp body 11 may still shake. In order to solve the above-mentioned problems, the present invention further improves the clamping device 20.

Specifically, as shown in fig. 3, in the present embodiment, the clamping member 200 is provided with an elastic pressure stabilizing slider 250, and the elastic pressure stabilizing slider 250 is slidably disposed in the clamping claw 210 (the clamping claw 210 is provided with a containing cavity 211) through a return spring 251, and a free end of the elastic pressure stabilizing slider 250 is located in the containing groove 220. The end of the clamping claw 210 is provided with an anti-falling blocking piece 212 (the anti-falling blocking piece 212 is the groove wall of the accommodating groove 220), a clamping gap is formed between the free end of the elastic voltage-stabilizing sliding block 250 and the anti-falling blocking piece 212, and the clamping gap is smaller than the thickness of the clamping blade 110. After the clamping blade 110 enters the accommodating groove 220, the elastic voltage stabilizing slider 250 and the anti-falling blocking piece 212 can clamp the axial direction of the clamping blade 110, so as to prevent the clamping blade 110 from shaking in the accommodating groove 220.

Preferably, as shown in fig. 3, 5 and 6, the holding blade 110 is provided with a guiding inclined plane 111, the guiding inclined plane 111 is located at a side of the holding blade 110 away from the clamping piece 200, an edge of the anti-falling blocking piece 212 is provided with a resistance chamfer 213 matched with the guiding inclined plane 111, and the guiding inclined plane 111 is used for assisting the holding blade 110 to enter the accommodating groove 220, and a specific working principle will be described below.

Preferably, as shown in fig. 4, in the limit position, the limit stop blocks 310 of the movable lock plate 300 cannot completely block both sides of the receiving groove 220, that is, in the case of no external force, the movable lock plate 300 abuts against the holding claws 210, and at this time, the limit stop blocks 310 cannot completely block both sides of the receiving groove 220, but only partially block the receiving groove 220. In addition, as shown in fig. 7, in the limit position, the distance from the end of the limit stop block 310 to the anti-falling stop piece 212 is smaller than the thickness of the holding blade 110, so that the limit stop block 310 can block the holding blade 110 in the accommodating groove 220 when no external force is applied.

The following describes the working principle of the improved clamping device 20 with reference to fig. 4 to 8:

when the lamp body is connected, firstly, the user corresponds the clamping seat 100 of the lamp body 11 to the clamping piece 200 of the mounting seat 13, namely, the clamping blade 110 and the jaw gap 240 are mutually corresponding, at this time, under the action of magnetic attraction force, the clamping blade 110 and the limit stop 310 are attached together, namely, the clamping blade 110 is positioned in the jaw gap 240, and since the distance from the tail end of the limit stop 310 to the anti-falling stop 212 is smaller than the thickness of the clamping blade 110, part of the height of the clamping blade 110 is already corresponding to the accommodating groove 220, as shown in fig. 5. Then, the user rotates the card holder 100 so that the card holding blade 110 enters the receiving groove 220;

in this process, as shown in fig. 6, the clamping blade 110 rotates to make the guiding inclined surface 111 contact with the resistance chamfer 213 and press the clamping blade 110, and as the clamping blade 110 further rotates, the clamping blade 110 gradually approaches the clamping member 200 and generates an axial thrust under the action of the guiding inclined surface 111, so that the clamping blade 110 overcomes the elastic force of the return spring 251 and lifts the elastic pressure-stabilizing slider 250. Thus, when the holding blade 110 completely enters the accommodating groove 220, the return spring 251 provides a holding force for the holding blade 110 through the elastic pressure stabilizing slider 250, so as to prevent the axial shake of the holding blade 110. Meanwhile, under the action of the guide inclined surface 111, the clamping blade 110 gradually approaches the clamping piece 200, so that the limit stop block 310 is pushed to make an avoidance action; as shown in fig. 7, after the clamping blade 110 completely enters the accommodating groove 220, the limiting blocking block 310 is reset under the action of the telescopic elastic piece 320, so that part of the accommodating groove 220 is blocked again, and the clamping blade 110 cannot rotate out of the accommodating groove 220;

when the lock is detached, as shown in fig. 8, a user only needs to overcome the elastic force of the telescopic elastic member 320 to push the movable lock collar 300 towards a direction away from the clamping claw 210, so that the limit stopper 310 is away from the accommodating groove 220, i.e. the limit stopper 310 no longer seals the accommodating groove 220; then, the user rotates the clamping seat 100 to make the clamping blade 110 rotate out of the accommodating groove 220, so that the clamping seat 100 and the clamping piece 200 can be separated smoothly.

It should be noted that, in the embodiment provided with the elastic pressure stabilizing slider 250, the clamping blade 110 enters the clamping gap by way of spin extrusion. During this time, the guide inclined surface 111 and the resistance chamfer 213 play an important role, and in particular, the guide inclined surface 111 has the following benefits: firstly, when the clamping blade 110 rotates to enter the clamping gap, the guiding inclined surface 111 presses the resistance chamfer 213, so that the force in the rotating direction is partially converted into the force for pushing the clamping seat 100, so that the clamping seat 100 jacks up the elastic voltage stabilizing sliding block 250 and compresses the return spring 251, namely under the guiding action of the guiding inclined surface 111, the clamping blade 110 does not need an operator to provide a pushing force in the direction of the clamping piece 200 when entering the clamping gap, and only the rotating force is needed to be applied to the clamping seat 100, so that the connection between the clamping seat 100 and the clamping piece 200 becomes easier and more convenient; secondly, when the clamping blade 110 is to be separated from the clamping gap, the guiding inclined surface 111 will press against the resistance chamfer 213 again when the clamping blade 110 is about to rotate out, at this time, the elastic pressure stabilizing slider 250 will provide a pressure for the clamping blade 110 under the action of the return spring 251, and the guiding inclined surface 111 will convert the pressure into a torque force for assisting the clamping blade 110 to separate from the clamping gap, so that the force is more saved during separation. Moreover, at the moment that the clamping blade 110 is completely separated from the clamping gap, the pressure provided by the elastic pressure stabilizing slider 250 disappears, at this time, the clamping blade 110 is no longer subjected to other forces, and the operator has a remarkable "loose hand" feel, which means that the clamping blade 110 rotates in place, and the clamping seat 100 can be smoothly separated from the clamping piece 200.

It is further noted that, in the process of releasing the holding blade 110 from the holding gap, when the holding blade 110 is about to rotate out, the elastic pressure stabilizing slider 250 will provide a pressure to the holding blade 110 under the action of the return spring 251, and since only a portion of the elastic pressure stabilizing slider 250 is pressed against the holding blade 110 at this time, the elastic pressure stabilizing slider 250 will incline (as shown in fig. 8), that is, the holding gap of one end of the elastic pressure stabilizing slider 250 having a pressure is larger than the holding gap of the other end not having a pressure, which means that the holding gap of the other end not having a pressure is smaller than the thickness of the holding blade 110. The design is mainly used for preventing an operator from forcefully and forcefully separating the clamping blade 110 from the clamping gap and extruding the clamping blade into the next clamping gap due to inertia. After such design, since the clamping gap at the other end is smaller than the thickness of the clamping blade 110, even if the operator applies excessive force, the clamping blade 110 will collide with the elastic pressure-stabilizing slider 250 of the next clamping gap after being separated from the previous clamping gap, so that the clamping blade will not be easily pushed into the next clamping gap.

In summary, the industrial lighting head lamp 10 with semiconductor light emitting diode of the present invention can not only make the lamp body 11 and the mounting base 13 quickly detachable, but also prevent the lamp body 11 from falling off during use, and at the same time prolong the service life of the mounting base 13.

The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
