The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in FIG. 1, the present invention provides an industrial lighting head lamp 10 with semiconductor light emitting diodes, which comprises a lamp body 11 and a head band 12, wherein the head band 12 is provided with a mounting seat 13, and the lamp body 11 and the mounting seat 13 are detachably connected through a clamping device 20. As shown in fig. 2, the latch 20 includes: joint seat 100, joint spare 200 and activity locking disc 300, joint seat 100 fixed mounting is on lamp body 11, and joint spare 200 fixed mounting is on mount pad 13, and activity locking disc 300 locates on joint spare 200 slidable. As shown in fig. 3, the clamping seat 100 is provided with a clamping blade 110, the clamping member 200 is provided with a clamping claw 210, the clamping claw 210 is provided with an accommodating groove 220 matched with the clamping blade 110, two sides of the accommodating groove 220 are open, the clamping blade 110 is accommodated in or separated from the accommodating groove 220, the movable locking disc 300 is provided with a limiting block 310, and the limiting block 310 is used for blocking two sides of the accommodating groove 220. The semiconductor light emitting diode is arranged in the lamp body 11, and the LED lamp is simple in structure, small in size, suitable for a low-current (20-200 milliamperes) working environment, low in power consumption, convenient to use and low in cost.

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

In the present embodiment, as shown in fig. 3, the number of the catching claws 210 is plural, the plural catching claws 210 are distributed in an annular array centering on the axis of the guide rod 230, and the number of the catching blades 110 matches the number of the catching 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 that 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 flexible elastic member 320 will push the movable locking disc 300 toward the clamping member 200, so that the movable locking disc 300 is supported on the clamping claw 210, at this time, the limiting blocking block 310 is located in the claw gap 240, and the limiting blocking block 310 will block the two sides of the accommodating groove 220. When in use, a user wears the head band 12 on the head, and then the clamping seat 100 of the lamp body 11 corresponds to the clamping piece 200, i.e. the clamping blades 110 on the clamping seat 100 correspond to the jaw gaps 240, as shown in fig. 4; then, the clamping blade 110 is pushed into the jaw gap 240, and at this time, the clamping blade 110 will abut against and push the limiting stopper 310, so that the accommodating 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, because the limiting blocking block 310 is no longer supported by the clamping blade 110, under the action of the telescopic elastic member 320, the limiting blocking block 310 plugs up the 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 member 200 are stably connected together, that is, the lamp body 11 is installed on the installation seat 13;

when the locking device is disassembled, a user only needs to overcome the elastic force of the elastic member 320 to push the movable locking disk 300 towards the direction far away from the clamping claw 210, so that the limiting blocking block 310 can be far away from the accommodating groove 220; subsequently, the user rotates the engaging seat 100 to rotate the engaging blade 110 out of the receiving slot 220, so as to smoothly separate the engaging seat 100 from the engaging member 200.

Thus, the lamp body 11 and the mounting seat 13 of the present invention are not connected by the conventional open type elastic snap, but by the snap connection between the snap seat 100 and the snap member 200. This kind of joint mode makes the joint back, and joint seat 100 can't break away from joint spare 200 by oneself to lamp body 11 drops in preventing the use again when making things convenient for the dismouting, and prolonged the life of mount pad 13.

Further, considering that a user needs to correspond the clamping blade 110 and the clamping jaw gap 240 to each other before installation, but the two are difficult to correspond to each other under the condition of insufficient light, in order to facilitate the operation of the user, the invention improves the limiting blocking block 310 and the clamping blade 110 so that the two can attract each other.

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

Furthermore, after the clamping seat 100 is connected to the clamping member 200, although the two sides of the clamping blade 110 are blocked by the limiting blocking block 310, so that the clamping blade 110 cannot be separated from the accommodating groove 220, the clamping blade 110 is not limited in the axial direction, and therefore the lamp body 11 still shakes. To solve the above problems, the present invention provides a further improvement of the latch 20.

Specifically, as shown in fig. 3, in the present embodiment, the elastic pressure-stabilizing slider 250 is disposed on the clip 200, the elastic pressure-stabilizing slider 250 is slidably disposed in the holding claw 210 through the return spring 251 (the receiving cavity 211 is disposed in the holding claw 210), and the free end of the elastic pressure-stabilizing slider 250 is disposed in the receiving cavity 220. The end of the holding claw 210 has an anti-falling blocking piece 212 (the anti-falling blocking piece 212 is the groove wall of the receiving groove 220), and a clamping gap is formed between the free end of the elastic pressure-stabilizing slider 250 and the anti-falling blocking piece 212, and the clamping gap is smaller than the thickness of the holding blade 110. After the clamping blade 110 enters the receiving groove 220, the elastic pressure-stabilizing slider 250 and the anti-dropping block piece 212 can clamp the axial direction of the clamping blade 110, thereby preventing the clamping blade 110 from shaking in the receiving groove 220.

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

Preferably, as shown in fig. 4, in the extreme position, the limit stopper 310 of the movable lock disk 300 cannot completely block the two sides of the accommodating groove 220, that is, the movable lock disk 300 abuts against the retaining claw 210 without external force, and at this time, the limit stopper 310 does not completely block the two sides of the accommodating groove 220, but only partially blocks the accommodating groove 220. Moreover, as shown in fig. 7, in the extreme position, the distance from the end of the spacing block 310 to the anti-falling block piece 212 is smaller than the thickness of the retaining blade 110, so that it can be ensured that the spacing block 310 can block the retaining blade 110 in the receiving slot 220 when no external force is applied.

The following explains the working principle of the improved latch device 20 with reference to the above structure, and please refer to fig. 4 to 8 together:

when connecting, firstly, the user makes the clamping seat 100 of the lamp body 11 correspond to the clamping member 200 of the mounting seat 13, that is, the clamping blade 110 corresponds to the claw gap 240, at this time, under the action of the magnetic attraction force, the clamping blade 110 is attached to the spacing block 310, that is, the clamping blade 110 is located in the claw gap 240, and since the distance from the end of the spacing block 310 to the anti-falling block piece 212 is smaller than the thickness of the clamping blade 110, a part of the height of the clamping blade 110 corresponds to the accommodating groove 220, as shown in fig. 5. Then, the user rotates the catching seat 100 so that the catching blade 110 enters the receiving groove 220;

in this process, as shown in fig. 6, the retaining blade 110 rotates to make the guiding inclined surface 111 contact and press the resistance chamfer 213, and as the retaining blade 110 further rotates, the retaining blade 110 will gradually approach the clip member 200 and generate an axial pushing force under the action of the guiding inclined surface 111, so that the retaining blade 110 overcomes the elastic force of the return spring 251 and jacks up the elastic pressure-stabilizing slider 250. Thus, when the catching blade 110 completely enters the receiving groove 220, the return spring 251 provides a pressing force to the catching blade 110 through the elastic pressure-stabilizing slider 250, thereby preventing the catching blade 110 from shaking axially. Meanwhile, under the action of the guide inclined surface 111, the clamping blade 110 gradually approaches the clamping piece 200, so that the limiting blocking block 310 is pushed to make an avoiding action; as shown in fig. 7, after the retaining blade 110 completely enters the accommodating slot 220, the limiting and blocking block 310 is reset under the action of the telescopic elastic member 320, so as to block part of the accommodating slot 220 again, so that the retaining blade 110 cannot rotate out of the accommodating slot 220;

during disassembly, as shown in fig. 8, the user only needs to overcome the elastic force of the elastic member 320 to push the movable locking disc 300 toward the direction away from the holding claws 210, so as to make the limiting blocking block 310 away from the accommodating slot 220, i.e. the limiting blocking block 310 no longer blocks the accommodating slot 220; then, the user rotates the engaging seat 100 to rotate the engaging blade 110 out of the receiving slot 220, so as to smoothly separate the engaging seat 100 from the engaging member 200.

It is noted that, in the embodiment provided with the elastic stabilizer blade 250, the catching blade 110 enters the clamping gap by means of rotational compression. During this period, the guide inclined surface 111 and the resistance chamfer 213 play an important role, and specifically, the guide inclined surface 111 has the following advantages: firstly, when the clamping blade 110 is to rotate to enter the clamping gap, the guide inclined plane 111 is pressed on the resistance chamfer 213, so that the force in the rotating direction is partially converted into a force for pushing the clamping seat 100, the clamping seat 100 jacks up the elastic pressure-stabilizing slider 250 and compresses the return spring 251, that is, under the guiding action of the guide inclined plane 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 needs 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, when the clamping blade 110 is to be rotated out, the guide inclined surface 111 thereon will press the resistance chamfer 213 again, at this time, the elastic pressure-stabilizing slider 250 will provide a pressure to the clamping blade 110 under the action of the return spring 251, and the guide inclined surface 111 will convert the pressure part into a torque force assisting the clamping blade 110 to be separated from the clamping gap, so as to make the separation more labor-saving. Moreover, at the moment when the clamping blade 110 is completely separated from the clamping gap, the pressure provided by the elastic pressure-stabilizing slider 250 disappears, and at this moment, the clamping blade 110 is not subjected to other acting forces, so that the operator has an obvious "loose-hand" feeling, which means that the clamping blade 110 rotates in place and the clamping seat 100 can be smoothly separated from the clamping member 200.

It should be further noted that, in the process of separating the holding blade 110 from the clamping gap, when the holding blade 110 is about to rotate out, the elastic pressure-stabilizing slider 250 provides a pressure to the holding blade 110 under the action of the return spring 251, and since only part of the elastic pressure-stabilizing slider 250 is pressed against the holding blade 110 at this time, the elastic pressure-stabilizing slider 250 tilts (as shown in fig. 8), that is, the clamping gap at one end of the elastic pressure-stabilizing slider 250 with pressure is larger than that at the other end without pressure, which means that the clamping gap at the other end without pressure is smaller than the thickness of the holding blade 110. The design is mainly used for preventing the operator from exerting too much force during operation, so that the clamping blade 110 is extruded into the next clamping gap due to inertia immediately after being separated from the clamping gap. With this design, since the clamping gap at the other end is smaller than the thickness of the clamping blade 110, even if the operator uses too hard force to separate the clamping blade 110 from the previous clamping gap, the clamping blade will collide with the elastic pressure-stabilizing slider 250 of the next clamping gap, so that the clamping blade will not be squeezed into the next clamping gap easily.

In summary, the industrial lighting headlamp 10 with semiconductor light emitting diodes of the present invention can not only make the lamp body 11 and the mounting seat 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 seat 13.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
