Referring to fig. 1 to 6, a working lamp 1 according to a preferred embodiment of the present invention is illustrated.

The work light 1 may be installed inside a hood 2 of a vehicle 1000 so as to project light to a space where an engine of the vehicle 1000 is located from top to bottom, so that a user can conveniently observe the space where the engine is located. The user can conveniently check and repair the space where the engine is located with the aid of the working lamp 1.

It is noted that the working lamp 1 may be installed in a trunk of the vehicle 1000 for trunk illumination, or may be installed in other positions of the vehicle 1000, such as a front window of the vehicle 1000, to provide illumination during outdoor activities.

Since the work light 1 can be mounted to the vehicle 1000, for example, the hood 2, the user does not need to hold the work light 1 by hand.

Specifically, the working lamp 1 includes a lamp holder 10, at least one mounting component 20, and at least one lamp body 30, wherein the mounting component 20 is mounted to the lamp holder 10, the lamp body 30 is mounted to the mounting component 20, and the lamp holder 10 is configured to be mounted to the engine cover 2 of the vehicle 1000. The lamp body 30 is used for emitting light, the mounting assembly 20 is used for mounting the lamp body 30, and the lamp holder 10 is used for supporting the mounting assembly 20 and the lamp body 30 to the engine cover 2 of the vehicle 1000.

The engine cover 2 has an outer surface and an inner surface, wherein the inner surface of the engine cover 2 is a surface facing the space of the engine, and the outer surface of the engine cover 2 is a surface facing the sky in general. The worklight 1 can be mounted to the hood 2 and is located on the inner surface side of the hood 2.

The lamp holder 10 comprises a lamp post 11 and two fixing members 12, wherein the two fixing members 12 are respectively located at two ends of the lamp post 11, and the fixing members 12 can be fixed to the engine cover 2. The lamp post 11 is supported by the engine cover 2 via the fixing member 12.

The light pole 11 can span the space of the vehicle 1000 where the engine is located. In this embodiment, the securing element 12 is a finger. Specifically, when the worklight 1 is mounted on the hood 2, the fixing member 12 extends from the end of the lamp post 11 to the outer surface of the hood 2, wherein the end of the lamp post 11 is located on the inner surface side of the hood 2. The entire task lamp 1 can be fixed to the hood 2 by hooking the fixing member 12 to the hood 2.

Of course, it is understood that the fixing member 12 may be fixed to the hood 2 by other methods, for example, the fixing member 12 may be fixed to the hood 2 by suction, adhesion, engagement, or the like. Alternatively, the engine cover 2 is designed to mount the worklight 1.

Further, the light pole 11 is arranged to be length adjustable. The position of the lamp body 30 mounted to the lamp post 11 can be changed as the length of the lamp post 11 is changed.

The pole 11 includes a pole body 111 and an adjusting lever 112, wherein the adjusting lever 112 is connected to the pole body 111, and the relative position between the pole body 111 and the adjusting lever 112 can be changed to change the length of the entire pole 11.

One of the two fixing members 12 is disposed at an end of the pole body 111 not connected to the adjusting lever 112, and the other is disposed at an end of the adjusting lever 112 not connected to the pole body 111.

When the length of the lamp post 11 is changed, the relative positions of the two fixing members 12 provided at both ends of the lamp post 11 are also changed, so that the entire working lamp 1 can be adapted to the covers 2 of different sizes.

For example, when the hood 2 is wide, the light pole 11 may be elongated, and when the hood 2 is narrow, the light pole 11 may be shortened.

Specifically, the light pole main body 111 has a receiving cavity 1110, wherein at least a portion of the adjusting rod 112 can be received in the receiving cavity 1110, and the adjusting rod 112 can move towards the receiving cavity 1110 to reduce the total length of the whole light pole 11, and the adjusting rod 112 can also move away from the receiving cavity 1110 to expand the total length of the whole light pole 11.

The outer section of the adjusting rod 112 is slightly smaller than the inner section of the lamp post body 111, so that the adjusting rod 112 can freely move back and forth in the accommodating cavity 1110.

It should be noted that, when the adjusting rod 112 is pulled out to extend the light pole 11, the adjusting rod 112 can be automatically retracted to the light pole main body 111 by removing the acting force applied to the adjusting rod 112.

Optionally, the adjustment lever 112 is itself elastic, for example made of a spring. When the adjustment lever 112 is stretched outwardly, the adjustment lever 112 itself may be elongated to fit the hood 2 of a larger size.

Alternatively, the adjusting rod 112 may be elastically connected to the post body 111, for example, the adjusting rod 112 and the post body 111 are connected through an elastic member, and the elastic member may be located inside the receiving cavity 1110 of the post body 111. When the adjusting lever 112 is stretched outward, the adjusting lever 112 moves outward and the elastic member between the adjusting lever 112 and the pole body 111 can be stretched, so that the entire length of the pole 11 is enlarged. When the force acting on the adjusting rod 112 stretching outward is removed, the adjusting rod 112 can be retracted into the light pole body 111 by the elastic member.

Further, the length of the pole body 111 itself may be changed. The position of the lamp body 30 mounted to the post body 111 can be changed according to the change in the length of the post body 111.

Specifically, the pole body 111 includes a first connection rod 1111 and a second connection rod 1112, wherein the first connection rod 1111 is connected to the second connection rod 1112, and the first connection rod 1111 has a first receiving cavity 11110, wherein the second connection rod 1112 can be received in the first receiving cavity 11110 of the first connection rod 1111, and the first connection rod 1111 can move along a length direction of the second connection rod 1112. The outer diameter of the second connecting rod 1112 is slightly smaller than the inner diameter of the first connecting rod 1111 so that the second connecting rod 1112 can move back within the first receiving cavity 11110 of the first connecting rod 1111.

That is, the length of the lamp post 11 can be adjusted, and can be extended or shortened. When the more the second connection rod 1112 is received in the first receiving cavity 11110 of the first connection rod 1111, the smaller the length dimension exhibited by the first connection rod 1111 and the second connection rod 1112, the shorter the length of the lamp pole 11. The smaller the portion of the first receiving cavity 11110 where the second connecting rod 1112 is received in the first connecting rod 1111, the larger the length dimension exhibited by the first connecting rod 1111 and the second connecting rod 1112, the longer the length of the light pole 11.

It is noted that the outer diameter and the inner diameter herein do not mean that the first connection rod 1111 and the second connection rod 1112 are circular tubes. The outer diameter of the first connection rod 1111 may be the maximum length of the cross-section of the space occupied by the outer surface of the first connection rod 1111, and the inner diameter of the second connection rod 1112 may be the maximum length of the cross-section of the space occupied by the inner surface of the second connection rod 1112.

The first connection rod 1111 and the second connection rod 1112 may be a triangular-section tube, a rectangular-section tube, an oval-section tube, etc., and it should be understood by those skilled in the art that the shape of the first connection rod 1111 and the second connection rod 1112 is not limited thereto, by way of example only.

The light pole 11 further comprises a fastener 113, wherein the fastener 113 is located at the junction of the first connection rod 1111 and the second connection rod 1112. The fasteners 113 are connected to the first connection rod 1111 and the second connection rod 1112, respectively. By the fastener 113, the stability of the connection of the first connection rod 1111 and the second connection rod 1112 or the stability of the connection of the first connection rod 1111 and the second connection rod 1112 after the relative positions are changed can be maintained.

Alternatively, when the fastener 113 is sleeved to the first connection rod 1111 and the second connection rod 1112. Different locations of the fastener 113 may form different inner diameters to match the outer diameters of the first connection rod 1111 and the second connection rod 1112, respectively. That is, the inner diameter of the fastener 113 may be tapered from one end to the other end.

The fastener 113 may fasten the first connection rod 1111 and the second connection rod 1112 by means of friction with the first connection rod 1111 and the second connection rod 1112.

The inner surface of the fastener 113 may be threaded to facilitate a tight connection between the fastener 113 and the first and second connecting

rods

1111, 1112.

When the work light 1 needs to be received, the second connecting rod 1112 can be at least partially received inside the first connecting rod 1111, thereby facilitating to reduce the space occupied by the work light 1.

Further, the light pole 11 comprises the adjusting rod 112, wherein the adjusting rod 112 is connected to the second connecting rod 1112. The relative positions of the adjustment lever 112 and the second connection rod 1112 may be adjusted.

Specifically, the overall length of the adjustment rod 112 and the second connecting rod 1112 may be shortened or lengthened.

The second connecting rod 1112 has a second receiving cavity 11120, wherein at least a portion of the adjusting lever 112 is received in the second receiving cavity 11120 of the second connecting rod 1112, and the adjusting lever 112 is movable within the second receiving cavity 11120 along a length direction of the second connecting rod 1112.

The more the adjusting rod 112 is received in the second receiving chamber 11120 of the second connecting rod 1112, the shorter the length of the whole lamp pole 11. The smaller the portion of the adjusting rod 112 received in the second receiving chamber 11120 of the second connecting rod 1112, the longer the entire length of the lamp pole 11.

It is noted that, in the present embodiment, one of the fixing pieces 12 is disposed at the end of the adjusting lever 112 not connected to the second connecting rod 1112, and the other fixing piece 12 is disposed at the end of the first connecting rod 1111 not connected to the second connecting rod 1112.

Due to the fastener 113 provided between the first connection rod 1111 and the second connection rod 1112, the relative position between the first connection rod 1111 and the second connection rod 1112 may be maintained fixed while the adjustment lever 112 is pulled out. That is, the length of the pole body 111 can be kept fixed, and the matching with the covers 2 of different sizes can be realized by adjusting the relative positions of the adjusting lever 112 and the pole body 111.

It is worth mentioning that the user does not need to precisely adjust the adjustment lever 112 and the pole body 111. The user can stretch the adjusting rod 112 outward to the length of the light pole 11 so that the two fixing members 12 are respectively aligned with the engine cover 2 at two sides of the engine cover 2, and then the user releases his hand, and under the action of the elastic force of the light pole 11, the length of the light pole 11 is automatically reduced so that the fixing members 12 can be automatically clamped with the engine cover 2.

That is, the worklight 1 can be mounted to the hood 2 without requiring complicated operations.

Note that, similarly, the work lamp 1 engaged with the hood 2 can be detached by a simple operation. For example, a user can pull the fixing member 12 outward at one side to detach the fixing member 12 from the hood 2, and then can easily detach the worklight 1 from the hood 2.

Further, it is noted that in the present embodiment, the shortest length of the lamp holder 10 of the working lamp 1 is limited to the first connection rod 1111. The adjustment lever 112 may be received in the second connection rod 1112, and the second connection rod 1112 may be received in the first connection rod 1111. That is, the cross-sectional dimension of the adjustment lever 112 is smaller than the second connection rod 1112, and the cross-sectional dimension of the second connection rod 1112 is smaller than the first connection rod 1111.

The entire lamp holder 10 of the work lamp 1 may be received to a length slightly greater than the first connection rod 1111, and at least portions of the adjustment rod 112 and the second connection rod 1112 may be exposed to facilitate pulling out during use.

Further, the working lamp 1 comprises the mounting assembly 20, wherein the mounting assembly 20 can be mounted to the lamp post body 111 or the adjusting rod 112.

It is worth mentioning that the mounting assembly 20 is position-changeably mounted to the lamp holder 10. The position of the mounting assembly 20 can be adjusted according to the user's needs, so that the position of the lamp body 30 mounted to the mounting assembly 20 can be adjusted, and thus the illumination position can be changed to meet different illumination needs of the user.

Specifically, the mounting assembly 20 has a sliding groove 200, wherein the lamp holder 10 can pass through the sliding groove 200. The mounting assembly 20 is movable along the lamp holder 10.

The mounting assembly 20 includes a sliding block 21 and a mounting seat 22, wherein the sliding groove 200 is formed on the sliding block 21, and the mounting seat 22 is mounted on the sliding block 21. By means of the sliding blocks 21, the relative position between the mounting seat 22 and the lamp holder 10 can be changed, wherein the lamp body 30 is mounted on the mounting seat 22, so that the relative position between the lamp body 30 and the lamp can be changed, and the position of the lamp body 30 in the space of the engine cover 2 can be adjusted according to the requirement.

Further, the mounting seat 22 is rotatably connected to the sliding block 21, so that the lamp body 30 mounted on the mounting seat 22 can rotate relative to the lamp holder 10, thereby facilitating adjustment of the illumination angle and orientation of the working lamp 1.

Optionally, the sliding block 21 and the mounting seat 22 are connected through a shaft hole, and the mounting seat 22 can rotate 360 ° relative to the sliding block 21.

Specifically, a connecting shaft 26 may pass through the sliding block 21 and the mounting seat 22, and the mounting seat 22 may rotate 360 ° around the connecting shaft 26. That is, the mount 22 can be rotated 360 ° about an axis passing through the slider 21 and the mount 22. In other words, the mount 22 is rotatably shaft-connected to the slider 21.

It is worth mentioning that the sliding block 21 itself can rotate around the lamp holder 10, so that the illumination direction of the lamp body 30 mounted on the mounting seat 22 can be changed, and the sliding block 21 can move back along the lamp holder 10, so that the illumination position of the lamp body 30 mounted on the mounting seat 22 can be changed.

From the aspect of lighting effect, the sliding block 21 can move back and forth along the length direction of the lamp post 11 of the lamp holder 10, so as to drive the lamp body 30 to move back and forth along the length direction of the lamp post 11, and thus the lighting position of the lamp body 30 can be adjusted back and forth along the lamp post 11. Further, the sliding block 21 can rotate around the axis of the lamp post 11, so that the lamp body 30 can rotate around the lamp post 11, and the lamp body 30 can radiate light outwards around the lamp post 11. In other words, the lamp body 30 can rotate 360 degrees around the lamp post 11. Further, the lamp body 30 is rotatably supported on the mounting seat 22 by the mounting seat 22, so that the lamp body 30 can be adjusted in three ways to adjust the illumination direction, thereby providing a plurality of adjustment ways for users. Further, the mounting seat 22 and the sliding block 21 can rotate relatively. For the lamp body 30, a multi-dimensional adjustment is possible.

It should be noted that the number of the sliding blocks 21 may be multiple, and when there are multiple locations in the space where the engine cover 2 is located to be maintained, each of the mounting assemblies 20 may be mounted with at least one of the lamp bodies 30, and one of the working lamps 1 may be responsible for lighting at least one area. For example, when there are two service personnel, one service personnel can use one lamp body 30.

Further, different mounting assemblies 20 are independent of each other, and two maintenance personnel can adjust the mounting assemblies 20 and the lamp body 30 according to their respective requirements without affecting the other.

It is worth mentioning that, after the relative position between the slider 21 and the lamp holder 10 is adjusted, the adjusted relative position between the slider 21 and the lamp holder 10 can be maintained, so that the lamp body 30 can be maintained at the adjusted angle and position.

Specifically, the sliding block 21 of the mounting assembly 20 has an adjustment opening 210, wherein the sliding block 21 includes a first partial sliding block 211 and a second partial sliding block 212, wherein the first partial sliding block 211 and the second partial sliding block 212 surround and form the sliding slot 200, and the sliding slot 200 is located between the first partial sliding block 211 and the second partial sliding block 212.

The adjusting opening 210 is communicated with the sliding groove 200, the adjusting opening 210 is formed between an end of the first partial slider 211 and an end of the second partial slider 212, and the adjusting opening 210 is an opening between the first partial slider 211 and the second partial slider 212.

The existence of the adjusting opening 210 means that a space is left between the first part sliding block 211 and the second part sliding block 212 for adjusting the relative positions of the first part sliding block 211 and the second part sliding block 212, so as to adjust the size of the sliding chute 200.

When the adjustment opening 210 is narrowed, the first partial sliding block 211 is close to the second partial sliding block 212, so that the sliding groove 200 is narrowed, and the sliding block 21 of the mounting assembly 20 can be fastened to the lamp holder 10. When the adjusting opening 210 is enlarged, the first partial sliding block 211 is far away from the second partial sliding block 212, so that the sliding groove 200 is enlarged, and the sliding block 21 of the mounting assembly 20 can easily move back and forth on the lamp holder 10 or rotate around to the lamp holder 10.

Further, the mounting assembly 20 includes an adjusting member 23, wherein the adjusting member 23 passes through the first partial block 211 and the second partial block 212, and the adjusting member 23 can be fixed to the adjusted positions of the first partial block 211 and the second partial block 212. The adjusting member 23 may be embodied as, but is not limited to, an adjusting bolt.

It is understood that the first partial slider 211 and the second partial slider 212 may be independent from each other, or the first partial slider 211 may be connected to the second partial slider 212, or even the first partial slider 211 may be integrally formed with the second partial slider 212. In this embodiment, the first partial slider 211 and the second partial slider 212 are integrally formed.

It should be noted that, by adjusting the adjusting member 23, the distance between the first partial sliding block 211 and the second partial sliding block 212 can be changed to adjust the size of the adjusting opening 210, so that the sliding block 21 can be fastened to the lamp post 11 of the lamp holder 10 or released from the position of the lamp post 11 of the lamp holder 10. In this way, the adjusting member 23 can be easily detached from or attached to the light pole 11.

The sliding block 21 has an inner surface 213, wherein at least a portion of the inner surface 213 of the sliding block 21 is a cambered surface, and when the sliding block 21 is installed on the lamp post 11 of the lamp holder 10, the portion of the inner surface 213 forming the cambered surface is adhered to the surface of the lamp post 11, the sliding block 21 can move back and forth along the surface of the lamp post 11, and when the adjusting element 23 releases the first partial sliding block 211 and the second partial sliding block 212, so that the distance between the first partial sliding block 211 and the second partial sliding block 212 is enlarged.

It is noted that the first partial slider 211 may be connected to the second partial slider 212, and the second partial slider 212 may be independent from the first partial slider 211.

The mounting assembly 20 further includes a magnetic element 24, wherein the magnetic element 24 is disposed on the mounting base 22, the lamp body 30 can be disposed with a magnetic element 25, wherein the magnetic element 24 and the magnetic element 25 can cooperate with each other to achieve a magnetic attraction effect.

Optionally, the magnetically attracting element 24 disposed on the mounting seat 22 is a magnetically attracting metal, such as iron, cobalt, nickel or a combination thereof. The magnetically engaging member 25 disposed on the lamp body 30 is a magnetically engaging substance, such as a magnet.

Of course, the magnetic element 24 disposed on the mounting seat 22 can also be a magnetic material, such as a magnet, and the magnetic engaging element 25 disposed on the lamp body 30 can be a magnetic metal, such as iron, cobalt, nickel or a combination thereof.

The lamp body 30 is detachably mounted to the mounting seat 22 by the magnetic attraction member 24 and the magnetic attraction engagement member 25 engaging with each other. The user can conveniently replace the lamp body 30 according to his or her own needs. For example, an incandescent lamp is replaced with an ultraviolet lamp.

Further, the mounting seat 22 of the mounting assembly 20 may be implemented as a wireless charging seat, and when the lamp body 30 is mounted on the mounting seat 22, the mounting seat 22 may supply power to the lamp body 30 to prolong the service life of the lamp body 30. Of course, the energy-depleted lamp body 30 may be directly removed from the mounting seat 22 and replaced with another lamp body 30 having sufficient energy.

Further, the lamp body 30 includes a mounting bracket 31 and a light emitting portion 32, wherein the light emitting portion 32 is used for emitting light, the light emitting portion 32 is supported on the mounting bracket 31, and the light emitting portion 32 is rotatably supported on the mounting bracket 31 relative to the mounting bracket 31. The mounting bracket 31 can be mounted to the mounting base 22 by, for example, magnetic attraction, or other detachable means such as engagement or screwing.

That is, the lamp body 30 can adjust the light irradiation angle and the light irradiation direction not only by changing the relative position between the mounting seat 22 and the slider 21 and the lamp holder 10, but also by changing the relative position between the light emitting portion 32 of the lamp body 30 itself and the mounting frame 31.

It should be noted that the lamp holder 10 of the working lamp 1 may be provided with a charging device, such as a rechargeable battery or a charger, wherein the charging device may be accommodated inside the lamp holder 10 and cannot be seen from the outside. The charging device may also be mounted outside the lamp holder 10.

The damping block 1133 is limited to the first connection rod 1111 and the second connection rod 1112, so as to limit the relative movement of the first connection rod 1111 and the second connection rod 1112, thereby locking the first connection rod 1111 and the second connection rod 1112.

The mounting assembly 20 includes the sliding block 21 and the mounting seat 22, wherein the sliding block 21 is formed with the sliding slot 200, and is mounted on the lamp post 11 of the lamp holder 10 through the sliding slot 200.

The mounting assembly 20 further comprises the adjusting member 23, wherein the adjusting member 23 is disposed on the sliding block 21 so that the sliding block 21 is locked to the lamp post 11 or freely moves along the lamp post 11. In detail, the adjusting element 23 includes an elastic connecting element 231, an adjusting switch 232, and an adjusting limiting element 233, wherein the elastic connecting element 231 is connected to the adjusting switch 232 in a linking manner, and the adjusting limiting element 233 is connected to the elastic connecting element 231 in a linking manner. The adjusting member 23 has an open state in which the slider 21 can move freely along the pole 11 and a closed state in which the slider 21 and the mounting base 22 are restrained to the pole 11.

Under the condition of no external force, the elastic connecting element 231 is located at the adjustment limiting element 233 on the slide block 21 at the lower limit of the elastic force to prevent the slide block 21 from freely moving.

When the adjusting switch 232 is operated to be turned on, the elastic connecting member 231 moves along with the adjusting switch 232, so as to drive the adjusting limiting member 233 to move away from the sliding block 21, so that the sliding block 21 can move along the lamp post 111 freely.

Further, the mount 22 is rotatably mounted to the slider 21 so that the illumination direction of the lamp body 30 mounted to the mount 22 can be changed.

At least one magnetically attractive element 24 may be disposed on the mounting seat 22, and at least one magnetically attractive engagement element 25 may be disposed on the lamp body 30, so that the lamp body 30 can be magnetically attracted to the mounting seat 22 and can be conveniently detached from the mounting seat 22.

The connecting shaft 26 passes through the mounting seat 22 and the slider 21, respectively, so that the mounting seat 22 is rotatably connected to the slider 21.

Further, the mounting assembly 20 includes an alignment assembly 27, wherein the alignment assembly 27 is connected to the mounting seat 22 and the sliding block 21, respectively. The alignment assembly 27 includes at least one alignment member 271 and at least one corresponding alignment elastic support 272, wherein the alignment member 271 is supported by the alignment elastic support 272, and the alignment elastic support 272 is supported by the slider 21. When the mounting seat 22 rotates relative to the slide block 21, the alignment assembly 27 remains fixed to the slide block 21. The mounting seat 22 forms at least one limiting groove 220, wherein the alignment assembly 27 can be limited in the limiting groove 220 to be aligned.

In detail, under the action of the aligning elastic support 272, the aligning member 271 is pressed against the mounting seat 22, and when the mounting seat 22 rotates until the limiting groove 220 is aligned with the aligning member 271, the aligning member 271 enters the limiting groove 220 under the action of the aligning elastic support 272.

For the user to operate, when the alignment member 271 enters the limiting groove 220, if the mounting seat 22 is to be rotated continuously, the force required to be applied by the user needs to be increased, so that the user can sense that the mounting seat 22 and the sliding block 21 are aligned. Of course, if the user wants to continue to rotate the mounting seat 22, the user can continue to increase the force.

Alternatively, the number of the alignment members 271 may be multiple, so as to provide multiple alignment positions, and the alignment members 271 may be arranged around the connecting shaft 26.

Preferably, the surface of the alignment member 271 contacting the mounting seat 22 may be an arc surface to facilitate smooth rotation of the mounting seat 22 relative to the alignment assembly 27. For example, the alignment member 271 can be a ball structure.

The alignment assembly 27 further includes a supporting plate 273, wherein the alignment member 271 is retained on the supporting plate 273, so that each alignment member 271 is maintained in a relatively fixed position, and even the alignment member 271 and the supporting plate 273 are integrally formed.

It is understood that, in the present embodiment, the aligning member 271 protrudes into the limiting groove 220. Alternatively, the alignment member 271 may be recessed, and the mounting seat 22 may be partially raised to position the alignment member 271. In other words, the mounting seat 22 provides a limiting position, which may be a groove or a protrusion.

Further, in this embodiment, the magnetic element 24 may be implemented as an iron block, and the magnetic engaging element 25 may be a magnet. The magnetically attractive element 24 is mounted to the mounting block 22, for example, by screws to the mounting block 22.

Further, referring to fig. 13 to 14B, the first connecting rod 1111 is a large pipe, the second connecting rod 1112 is a middle pipe, and the adjusting rod 112 is a small pipe.

The second connecting rod 1112 is received within the first connecting rod 1111 and is movable back and forth along an inner wall of the first connecting rod 1111. The first connection rod 1111 and the second connection rod 1112 can be locked by the fastener 113.

The adjustment lever 112 is received by the second connection rod 1112 and is at least partially receivable by the first connection rod 1111. In other words, at least portions of the first connection rod 1111, the second connection rod 1112, and the adjustment rod 112 may overlap each other.

The connection of the first connection rod 1111 and the second connection rod 1112 will be described first. The second connecting rod 1112 has a connecting end and a free end, wherein the connecting end is located within the first connecting rod 1111 and is provided with a second connecting rod sealing ring 13 such that the connecting end of the second connecting rod 1112 and the first connecting rod 1111 form a relatively closed buffer space 130.

With the damping space, when the second connecting rod 1112 moves back relative to the first connecting rod 1111, the damping space 130 is relatively closed, so as to perform a damping function, for example, damping the impact of the second connecting rod 1112 on the first connecting rod 1111 when the second connecting rod 1112 moves fast in the first connecting rod 1111.

In detail, when the second connecting rod 1112 moves inwards, the buffer space is relatively closed, and air cannot flow in time, so that the pressure in the buffer space 130 is increased, the moving resistance of the second connecting rod 1112 is increased, and the buffer effect on the second connecting rod 1112 is achieved.

Further, the adjustment rod 112 is telescopically coupled to the second connecting rod 1112 with respect to the second connecting rod 1112. The adjustment lever 112 has a connecting end and a free end, wherein the connecting end of the adjustment lever 112 is connected to the second connecting rod 1112, and the free end of the adjustment lever 112 is connected to the fixing member 12. The lamp holder 10 further comprises an adjusting rod sealing ring 14, wherein the adjusting rod sealing ring 14 is disposed at the connecting end of the adjusting rod 112 such that a relatively closed buffer cavity 140 is formed between the connecting end of the adjusting rod 112 and the second connecting rod 1112. Similarly, the damping chamber 140 may perform a damping function when the adjustment lever 112 moves relative to the second connection rod 1112.

The lamp holder 10 further includes an elastic connection member 15, wherein one end of the elastic connection member 15 is connected to the second connection rod 1112, and the other end is connected to one of the fixing members 12. The elastic connection 15 passes through the adjustment lever 112 and elastically movably connects the adjustment lever 112 to the second connection rod 1112.

The resilient connecting member 15 passes through the adjustment rod sealing ring 14 and can still maintain a relatively closed buffer chamber 140 between the second connecting rod 1112 and the connecting end of the adjustment rod 112.

In detail, the cross-section of the adjusting rod sealing ring 14 is set to be larger closer to the connection end of the second connection rod 1112. I.e. the closer to the regulating rod 112, the smaller the cross section of the regulating rod sealing ring 14.

The adjusting rod sealing ring 14 can be designed in a trumpet shape, with the trumpet opening towards the second connecting rod 1112. The maximum cross-sectional position of the adjustment rod seal 14 contacts the second connection rod 1112. That is, the resistance at the connection of the adjustment lever 112 and the second connection rod 1112 is small.

When the adjustment lever 112 is moved outward away from the second connection rod 1112, the elastic connection member 15 is extended such that the diameter of the elastic connection member 15 becomes smaller, so that a gap is formed at the connection of the elastic connection member 15 and the adjustment lever sealing ring 14 to exhaust air. When the adjustment lever 112 is pushed inward to be close to the connection end of the second connection rod 1112, the elastic connection member 15 is automatically contracted, so that the diameter of the elastic connection member 15 becomes large, so that the connection of the elastic connection member 15 and the adjustment lever sealing ring 14 is maintained relatively closed, thereby buffering the movement of the adjustment lever 112.

Referring to fig. 17 to 21, the lamp holder 10 of the working lamp 1 is telescopic in length, so that a user can adjust the length as required and the lamp holder 10 can be fixed at an adjusted position by the fastening member 113. The lamp body 30 can be conveniently detachably mounted to the mounting assembly 20, and the mounting seat 22 of the mounting assembly 20 can be rotated with respect to the slider 21 so that the illumination direction of the lamp body 30 can be adjusted.

According to another aspect of the present invention, the present invention provides a method of operating the lamp holder 10, which includes the steps of:

the second connection rod 1112 received in the first connection rod 1111 is pushed in a direction close to the first connection rod 1111, and the impact of the second connection rod 1112 on the first connection rod 1111 is buffered by the buffering space 130 formed in the first connection rod 1111 and the second connection rod 1112.

According to an embodiment of the present invention, the adjustment lever 112 received in the second connection rod 1112 is pushed in a direction approaching the second connection rod 1112, and the impact of the adjustment lever 112 on the second connection rod 1112 is buffered by the buffer cavities 140 formed in the second connection rod 1112 and the adjustment lever 112.

According to an embodiment of the present invention, the second connecting rod 1112 and the adjusting rod 112 are elastically connected by the elastic connection member 15, and the elastic connection member 15 passes through the adjusting rod sealing ring 14 disposed at the end of the second connecting rod 1112, when the adjusting rod 112 moves in a direction away from the second connecting rod 1112, the cross section of the elastic connection member 15 is reduced so that a gap is formed between the elastic connection member 15 and the adjusting rod 112 to communicate the inside and the outside of the adjusting rod sealing ring 14, and when the adjusting rod 112 moves in a direction close to the second connecting rod 1112, the cross section of the elastic connection member 15 is enlarged so that the elastic connection member 15 and the adjusting rod 112 are closely connected, thereby preventing air in the buffer cavity 140 from flowing out to buffer the adjusting rod 112.

It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are given by way of example only and are not limiting of the invention. The objects of the present invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
