White LEDs are regarded as the fourth-generation lighting source to replace fluorescent lamps and incandescent lamps. LEDs change the principle of tungsten wire light emission in incandescent lamps and trichromatic phosphor light emission in fluorescent lamps, and use electric field to emit light, with the advantages of high luminous efficiency, no radiation, long lifespan, low power consumption, and environmental protection. In building construction, there are many night operations and operations in enclosed spaces. Therefore, LED lighting equipment is widely used in construction to meet the lighting needs of on-site construction operations. The lamp holders of existing LED lighting lamps are adjustable, and different lighting ranges and effects can be achieved by adjusting the height of the lamp holder and fixing it.

[0003] For this reason, a Chinese invention authorization patent with the patent number CN105135377B discloses a lighting lamp holder, including a base, a chute is fixedly arranged inside the base, a pulley is slidably arranged in the chute through a transmission mechanism, and the transmission mechanism drives the pulley to move linearly along the chute; a telescopic frame is arranged on the base and fixedly connected to the pulley, and the telescopic frame makes a lifting movement driven by the pulley; a lamp holder is fixedly arranged at the top of the telescopic frame; a lighting lamp is fixedly arranged on the lamp holder. The pulley moves linearly along the chute driven by the transmission mechanism, and the telescopic frame further makes a lifting movement driven by the pulley, thereby realizing a telescopic lighting lamp holder, which is simple to operate, convenient to use, and meets the requirements of green construction.

[0004] However, through the cooperation of the pulley, chute, telescopic frame, handle, and stop piece, the above device can only adjust and fix the height of the lamp holder, and it is not convenient to adjust the angle of the lighting lamp on the lamp holder, which will also affect the lighting effect to a certain extent and the use flexibility is poor. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the present invention provides a lamp holder fixing device for an LED lighting lamp, which has the advantages that the sliding transmission part can be flexibly matched with the height adjusting part and the angle adjusting part to realize the adjustment of the height of the lighting lamp and the irradiation angle, with flexible use and wide application range, and the brushing part occupies a small space and is convenient for timely cleaning of the lighting lamp to ensure its light output effect, thereby effectively enhancing the lighting efficiency. It solves the problem that in the prior art, through the cooperation of the pulley, chute, telescopic frame, handle, and stop piece, only the height of the lamp holder can be adjusted and fixed, and it is not convenient to adjust the angle of the lighting lamp on the lamp holder, which will also affect the lighting effect to a certain extent and the use flexibility is poor.

[0006] The present invention is implemented as follows. A lamp holder fixing device for an LED lighting lamp includes a base, on which a support tube is fixedly installed. A height adjusting member is slidably connected inside the front of the support tube. The height adjusting member includes a support plate, and the top of the support plate is connected to a toothed disc through a bearing. A lighting lamp head is fixedly installed on the toothed disc. An angle adjusting member is slidably connected inside the back of the support tube. The angle adjusting member includes a rack. A sliding transmission member is disposed through between the two sides of the support tube. The sliding transmission member includes a gear. The front end of the gear is meshed and connected to the middle of the support plate, and the rear end of the gear is meshed and connected to the rack. A brushing member is fixedly installed on the front of the support tube, and the lower end of the brushing member can perform a brushing movement on the end face of the lighting lamp head.

[0007] With this setting, during use, through the cooperation of the sliding transmission member and the height adjusting member, the height adjustment operation of the lighting lamp head is realized. Then, by pushing the sliding transmission member to cooperate with the angle adjusting member, the angle adjustment operation of the lighting lamp head is realized, which is convenient for quickly adjusting the lighting range, saving time and effort, and being flexible and effective in enhancing the lighting efficiency. If it is necessary to clean the dust on the lampshade at the end face of the lighting lamp head, the angle adjusting member can be made to drive the lighting lamp head to rotate downward to realize the cooperation with the brushing member, so that the brushing member sweeps the dust on the lampshade of the lighting lamp head, thereby effectively ensuring the light output effect of the lighting lamp head, which is beneficial to further enhancing the lighting efficiency.

[0008] Preferably, a guiding block is fixedly connected to the front of the support plate, a guiding groove is formed on the front of the support tube, and the guiding block slides along the guiding groove. Teeth are provided in the middle of the back of the support plate and are meshed with the gear. Uniformly distributed first fixing grooves are formed on both side walls of the support plate, and first fixing members are installed on both side walls of the support tube. The first fixing member includes a first fixing block, and the first fixing block is slidably clamped into the first fixing groove.

[0009] With this setting, during use, the guiding block slides along the guiding groove, effectively ensuring the stability of the connection structure between the support plate and the support tube, making the telescopic movement of the support plate driving the lighting lamp head for height adjustment operate smoothly, which is beneficial to ensuring the adjustment efficiency and accuracy. When adjusting the height of the lighting lamp head, the rotation of the gear can drive the teeth to move upward, thereby facilitating the driving of the support plate to move upward. At this time, the first fixing block will repeatedly make an elastic clamping or sliding out movement in the first fixing groove until the support plate drives the lighting lamp head to reach the specified height. At this time, the gear disengages from the teeth, causing the support plate to stop moving upward, and the first fixing block is clamped into the corresponding first fixing groove to firmly limit the support plate, thereby realizing the effective positioning of the height adjustment position.

[0010] Preferably, the first fixing member further includes a fixing cylinder fixedly connected to the side wall of the support tube. The first fixing block is wedge-shaped and slidably connected to the inside of the fixing cylinder.

A first limiting block is fixedly connected to the first fixing block, and a first limiting groove is formed in the fixing cylinder. The first limiting block slides along the first limiting groove.

[0011] With this arrangement, during use, when the support plate moves upward or downward, due to the elastic force of the first spring and the driving force during the movement of the support plate, the first fixing block squeezes the first spring and retracts into the fixing cylinder, that is, disengages from the first fixing groove, and the first fixing block resets and extends out of the fixing cylinder and slides into the first fixing groove. When the support plate stops moving, the first fixing block will snap into the first fixing groove at the corresponding position to achieve stable support for the support plate, and it is flexible to use.

[0012] Preferably, the bottom end of the support plate is fixedly connected to a support box through a support rod. The support box is slidably connected to the back of the support tube. An accommodation cavity is provided inside the support box. The rack is located on the accommodation cavity and is slidably connected thereto. Installation grooves are formed at both ends of the top of the accommodation cavity, and second fixing members are provided on the installation grooves.

[0013] With this arrangement, during use, the stability of the connection structure between the rack and the support box is effectively improved. When the support plate moves for height adjustment, it will drive the support box and the rack to move synchronously. When performing angle adjustment operations, it is convenient for the rack to maintain a stable meshing connection state with the gear disc of the lighting head, which is convenient for operation.

[0014] Preferably, the second fixing member includes a second fixing block. The second fixing block is wedge-shaped and slidably connected to the installation groove. One end of the second fixing block is fixedly connected to the installation groove through a second spring. A second limiting block is fixedly connected to the side wall of the second fixing block. A second limiting groove is formed in the groove wall of the installation groove. The second limiting block slides along the second limiting groove. Uniformly distributed second fixing grooves are formed on both side walls of the rack, and the other end of the second fixing block slides into the second fixing groove.

[0015] With this setting, during use, when the gear drives the rack to move telescopically, due to the elastic force of the second spring and the driving force during the movement of the rack, the second fixing block squeezes the second spring and retracts into the mounting groove, that is, disengages from the second fixing groove, and the second fixing block resets and extends out of the mounting groove and slides into the second fixing groove. When the rack stops moving, the second fixing block will snap into the second fixing groove at the corresponding position to achieve stable support for the rack, and then achieve stable support for the toothed disc by the rack, thereby achieving adjustment and fixation of the rotation angle of the lighting head, with flexible use.

[0016] Preferably, a sliding seat is penetrated and arranged between the two sides of the support tube. The gear is located inside the sliding seat, and one end of the gear is connected to the sliding seat through a bearing. A motor is fixedly installed on the inner wall of the sliding seat, and the output end of the motor is fixedly connected to the other end of the gear.

[0017] With this setting, during use, start the motor to drive the gear to rotate, and then drive the tooth and the support plate to move telescopically through the rotating gear to achieve the height adjustment operation of the lighting head, and drive the rack to move telescopically through the rotating gear, and then drive the toothed disc to rotate by the rack, thereby achieving the angle adjustment operation of the lighting head.

[0018] Preferably, a slider is fixedly connected to the middle of the outer wall of the sliding seat. Sliding grooves are opened on both side walls of the support tube. The slider moves back and forth along the sliding groove. The rear end surface of the slider is fixedly connected to the sliding groove through a straight spring. A handle is fixedly connected to the outer side wall of the slider.

[0019] With this setting, during use, when performing the angle adjustment operation of the lighting head, hold the handle and push the sliding seat. At this time, the slider moves along the sliding groove and squeezes the straight spring, so that the sliding seat can drive the gear to move, and the gear can be moved to the meshing position with the rack, and then drive the rack to move telescopically, and the rotation of the toothed disc can be realized to adjust the irradiation angle of the lighting head. When performing height adjustment, release the handle. At this time, the straight spring drives the gear to reset to the tooth of the support plate, so that the gear and the tooth are meshed, and then drive the telescopic movement on the support plate to achieve the height adjustment operation of the lighting head. After all adjustments are completed, just turn off the motor, with flexible and fast use.

[0020] Preferably, the brushing member includes a bent pipe, the bent pipe is fixedly connected to the front surface of the support tube, an elastic plastic rod is slidably connected inside the bent pipe, the upper end of the elastic plastic rod penetrates and extends out of the outside of the bent pipe, the lower end of the elastic plastic rod is fixedly connected to a brushing plate, and bristles are fixedly connected to the inner side of the brushing plate, and the bristles are closely attached to the end surface of the lighting head.

[0021] With this setting, during use, when dust covers the end face lampshade of the lighting lamp head and affects the light output and illumination effect, the rack drives the gear disk to rotate downward, that is, drives the lighting lamp head to rotate downward, so that the side wall of the lighting lamp head abuts against the upper end of the elastic plastic rod, and then pushes the upper end of the elastic plastic rod to gradually retract into the bent pipe, driving the lower end of the elastic plastic rod to gradually extend obliquely upward out of the bent pipe, and then driving the brush sweeping plate to extend upward, so that the bristles closely adhere to the surface of the lampshade to push and sweep the dust. When the lighting lamp head rotates upward and disengages from the elastic plastic rod, it can drive the elastic plastic rod and the brush sweeping plate to reset. The dust on the lighting lamp head can be conveniently cleaned by the brushing member, and it occupies a small volume on the lamp holder and is not easy to block and interfere with the lighting lamp head during use, effectively ensuring its light output effect and enhancing the lighting efficiency, which is conducive to further enhancing the use efficiency of this device.

[0022] Preferably, a stopper is fixedly connected to the upper end of the elastic plastic rod, and the stopper and the end of the bent pipe are fixedly connected by an inclined spring, and the side wall of the lighting lamp head abuts against the stopper.

[0023] With this setting, during use, when the side wall of the lighting lamp head abuts against the upper end of the elastic plastic rod, it will abut against the stopper and squeeze the inclined spring, which is convenient for the bristles at the lower end of the bent pipe to extend out to push and sweep the end face of the lighting lamp head. After cleaning, when the lighting lamp head rotates upward and disengages from the stopper, the inclined spring can drive the stopper, the brush sweeping plate and the bristles to reset, and the operation is convenient.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the combined action of the sliding transmission member and the height adjustment member, the height adjustment operation of the lighting lamp head is realized.
