Description
Technical Field
[0001] The present invention relates to the technical field of lighting fixtures, and in particular to a lamp lifter. Background Art
[0002] At present, lamps are usually installed in fixed ways such as ceiling, embedded, and hoisting. After installation, they have poor flexibility, fixed lighting range, and cannot be adjusted according to actual use needs. Especially for industrial and mining lamps used in production areas of factories and mines, due to the high height of the above space, in order to achieve the ideal lighting effect, it is necessary to increase the number of lamps or use high-power lamps, which significantly increases the cost of use. Therefore, it is urgent to design a lifter that can adjust the height of the lamp to achieve a good lighting effect. Summary of the invention
[0003] The technical problem to be solved by the present invention is to overcome the above-mentioned problem and provide a lamp lifter capable of adjusting the height of the lamp, which can significantly enhance the lighting effect and is particularly suitable for industrial and mining lamps in factory workshops and other occasions.
[0004] The technical solution of the present invention is:
[0005] A lamp lifter described in the present invention includes a base and a cover shell, and is characterized in that: a spring seat that can move up and down is provided at the lower part of the base, and a lamp mounting plate for mounting the lamp is provided at the lower part of the spring seat; a wire rope traction mechanism for lifting and lowering the spring seat and the lamp mounting plate, a power drive mechanism for driving the wire rope traction mechanism, and a power supply control mechanism electrically connected to the power drive mechanism are provided on the base; a spring conductive coil is provided in the spring seat, and the spring conductive coil is fixedly connected between the base and the spring seat, and the two ends are electrically connected to the power supply control mechanism and the lamp respectively; a circuit travel switch is also provided on the base, which is in a state of contact or separation with the spring seat, and the circuit travel switch is electrically connected to the power supply control mechanism, and is used to control the circuit disconnection or conduction between the external power supply and the spring conductive coil and the power drive mechanism.
[0006] By means of the above structure, the present invention drives the wire rope traction mechanism through the power drive mechanism to achieve the adjustment of the up and down lifting height of the spring seat and the lamp mounting plate. When the spring seat descends relative to the base and separates the spring seat from the circuit travel switch, the power supply control switch controls the spring conductive coil and the power supply circuit on the power drive mechanism to be in a conducting state, and the lamp is lit by the energization of the spring conductive coil, and the power drive mechanism can continue to drive to achieve lifting and lowering adjustment; when the spring seat touches the circuit travel switch upward, the power supply control switch cuts off the power supply circuit on the spring conductive coil and the power drive mechanism, so that the power drive mechanism no longer drives the lifting and the lamp is extinguished.
[0007] Furthermore, in the lamp lifter of the present invention, the wire rope traction mechanism includes a wire wheel, a movable pulley, and a wire rope. The wire wheel can be rotatably arranged on the base and connected to the power drive mechanism. The movable pulley can be rotatably arranged on the lamp mounting plate. The wire rope is wound around the wire wheel and fixed to it at one end, and the other end passes through the base, the spring seat and the movable pulley in sequence downward, and then passes through the spring seat upward and is fixed to the base. This structure uses a movable pulley structure to achieve the purpose of double-line traction of the lamp mounting plate, so that the spring seat and the lamp mounting plate are more stable during the lifting process and are not easy to shake or rotate.
[0008] Furthermore, in the lamp lifter of the present invention, a wire arrangement mechanism is provided on one side of the wire winding wheel, and the wire arrangement mechanism includes a wire arrangement wheel and a wire arrangement wheel shaft, the central axis of the wire arrangement wheel shaft is parallel to the central axis of the wire winding wheel, the wire arrangement wheel is sleeved on the wire arrangement wheel shaft and can be slidably matched along the axial direction of the wire arrangement wheel shaft, and the wire arrangement wheel is provided with a circle of wire grooves, and the wire rope is wound in the wire grooves of the wire arrangement wheel and then wound on the wire winding wheel. In the process of winding the wire rope on the wire winding wheel, the wire arrangement wheel slides back and forth along the wire arrangement wheel shaft, so that the wire rope can be neatly and evenly arranged on the wire winding wheel without local stacking.
[0009] Furthermore, in the lamp lifter of the present invention, a wire guide mechanism is also included, the wire guide mechanism includes a first wire guide wheel and a second wire guide wheel, the central axis of the first wire guide wheel is perpendicular to the central axis of the wire winding wheel, the central axis of the second wire guide wheel, the central axis of the wire winding wheel, and the horizontal line are parallel, and the wire rope passes through the first wire guide wheel and the second wire guide wheel in sequence and then hangs down through the base. The setting of the wire guide mechanism can guide the direction of the wire rope and avoid the deviation of the wire rope during operation.
[0010] Furthermore, in the lamp lifter described in the present invention, a plurality of wire guide rods are provided at the outer edges of the first wire guide wheel and the second wire guide wheel, and the central axes of the wire guide rods are respectively parallel to the central axes of their corresponding wire guide wheels, and a wire guide channel is formed between the wire guide rods and the circumferential outer edges of their corresponding wire guide wheels, so that the wire rope can pass through and be pressed against the surface of the wire guide wheel to prevent the wire rope from detaching from the wire guide wheel.
[0011] Furthermore, in the lamp lifter described in the present invention, the upper end surface of the spring seat is provided with an inwardly concave annular spring cavity and a boss surrounded by the annular spring cavity, the spring conductive coil is arranged in the annular spring cavity, and the boss is in contact with or separated from the circuit travel switch; the lower end surface of the spring seat is recessed with a bottom mounting cavity, and the lamp mounting plate is detachably arranged at the bottom opening of the bottom mounting cavity.
[0012] Furthermore, in the lamp lifter described in the present invention, a power interface for connecting to an external power source is provided on the cover, and the power interface is electrically connected to the power supply control mechanism, the spring conductive coil, and the power drive mechanism.
[0013] Furthermore, in the lamp lifter described in the present invention, the power drive mechanism is a motor, and the motor is connected to the wire winding wheel to drive the motor to rotate.
[0014] Furthermore, the lamp lifter of the present invention also includes a remote control controller connected to the power supply control mechanism, which can be used to control the operation of the power drive mechanism.
[0015] Furthermore, in the lamp lifter described in the present invention, hooks are provided on the upper portion of the cover shell and the lower portion of the lamp mounting plate.
[0016] The beneficial effects of the present invention are:
[0017] 1. The present invention has a simple structure and a novel design. It can flexibly adjust the hanging height of the lamp according to actual usage conditions. The lamp is kept in a conducting and lighting state during the lifting process. The height of the lamp can be adjusted while observing the illumination range and brightness, which significantly improves the adjustment speed and lighting effect. It can be promoted and used on various lighting fixtures and has a wide range of applications, especially suitable for indoor tall factories, such as factory workshops, airport waiting halls, hangars and other places.
[0018] 2. When the lamp rises to the highest point, the present invention can automatically cut off the power supply circuit through the cooperation of the spring seat and the circuit travel switch, so that the power drive mechanism stops running and the lamp is extinguished, thereby protecting the wire traction mechanism and further improving safety and reliability.
[0019] 3. The present invention designs a movable pulley structure so that the steel wire rope forms a circular double-line traction on the lamp mounting plate, which greatly improves the lifting and lowering stability of the spring seat and the lamp mounting plate, and avoids shaking, rotation, etc. of the spring seat and the lamp mounting plate during the lifting process due to the elastic connection of the spring conductive coil.
[0020] 4. The present invention arranges a wire arrangement mechanism on one side of the winding wheel, and uses the automatic sliding of the wire arrangement wheel on the wire arrangement wheel shaft to ensure that the wire rope is arranged neatly and evenly on the winding wheel, avoiding the accumulation and twisting of the wire rope, thereby improving the wire arrangement quality.
[0021] 5. The present invention adds a wire guide wheel on the path of the wire rope, which can smoothly guide the direction of the wire rope, accurately thread the wire, and cooperate with the wire guide rod to limit the movement space of the wire rope, keeping the wire rope in a taut state during the winding and releasing process without deviation.

The base 2 is also provided with a circuit travel switch 7 which is in contact with or separated from the spring seat 3. The circuit travel switch 7 is electrically connected to the power supply control mechanism 5 and is used to control the circuit between the external power supply and the spring conductive coil 6 and the power drive mechanism 16 to be disconnected or connected.
[0027] The upper end surface of the spring seat 3 is provided with a concave annular spring cavity 301 and a boss 302 surrounded by the annular spring cavity 301. The spring conductive coil 6 is arranged in the annular spring cavity 301. The boss 302 contacts or separates with the circuit travel switch 7. The lower end surface of the spring seat 3 is recessed with a bottom installation cavity 303. The lamp installation plate 4 is detachably arranged at the bottom opening of the bottom installation cavity 303. It should be noted that the plane where the boss 302 is located should be arranged slightly higher than the upper end surface of the spring seat 3, so that it protrudes and can touch the circuit travel switch 7.
[0028] Specifically, in combination Figure 2 and Figure 3The wire rope traction mechanism includes a winding wheel 8, a movable pulley 9, and a wire rope 10. The winding wheel 8 is rotatably arranged on the base 2 and connected to a power drive mechanism 16. The power drive mechanism 16 is a motor, and the motor is connected to the winding wheel 8 to drive it to rotate. The movable pulley 9 is rotatably arranged on the lamp mounting plate 4. The wire rope 10 is wound around the winding wheel 8 and fixed to it at one end, and the other end passes through the base 2, the spring seat 3 downwards in sequence and around the movable pulley 9, and then passes through the spring seat 3 upwards and is fixed to the base 2.
[0029] A wire arrangement mechanism is provided on one side of the wire winding wheel 8, and the wire arrangement mechanism includes a wire arrangement wheel 12 and a wire arrangement wheel shaft 11. The central axis of the wire arrangement wheel shaft 11 is parallel to the central axis of the wire winding wheel 8. The wire arrangement wheel 12 is sleeved on the wire arrangement wheel shaft 11 and can be slidably matched along the axial direction of the wire arrangement wheel shaft 11. The wire arrangement wheel 12 is provided with a circle of steel wire grooves, and the steel wire rope 10 is wound in the steel wire grooves of the wire arrangement wheel 12 and then wound on the wire winding wheel 8. In this structure, the wire arrangement wheel 12 is slidably sleeved on the wire arrangement wheel shaft 11 through a bearing, and a retaining spring is respectively provided between the axial end surfaces of the wire arrangement wheel 12 and the bearing so that the two ends of the wire arrangement wheel 12 are pressed against the bearing to achieve positioning.
[0030] This embodiment includes a wire guide mechanism, which includes a first wire guide wheel 13 and a second wire guide wheel 14. The central axis of the first wire guide wheel 13 is perpendicular to the central axis of the wire winding wheel 8, and the central axis of the second wire guide wheel 14, the central axis of the wire winding wheel 8, and the horizontal line are parallel. The steel wire rope 10 passes through the first wire guide wheel 13 and the second wire guide wheel 14 in sequence and then hangs down through the base 2. A plurality of wire guide rods 15 are provided at the outer edges of the first wire guide wheel 13 and the second wire guide wheel 14. The central axes of the wire guide rods 15 are respectively parallel to the central axes of the corresponding wire guide wheels, and a wire guide channel is formed between the wire guide rods 15 and the outer edges of the circumferences of the corresponding wire guide wheels, so that the steel wire rope 10 can pass through and be pressed against the surface of the wire guide wheel. In the above structure, the wire rope 10 is led out from the wire winding wheel 8, and hangs down to the movable pulley 9 through the wire arrangement wheel 12, the first wire guide wheel 13, and the second wire guide wheel 14, and then bypasses the movable pulley 9 and returns to the base 2 upward, thereby forming a circular double-line traction for the lamp mounting plate 4, thereby improving the lifting stability.
[0031] This embodiment also includes a remote controller connected to the power supply control mechanism 5, which is used to control the operation of the power drive mechanism 16. The forward and reverse operation of the power drive mechanism 16 can be remotely controlled, and the remote controller can be used to stop the lifting after the lifting is adjusted to an appropriate height.
[0032] During installation, the structure fixes the cover 1 and the base 2 through the hook on the upper part of the cover 1, and installs the lamp through the hook on the lower part of the lamp mounting plate 4 and connects the lamp to the lower end of the spring conductive coil 6. At this time, the boss 302 of the spring seat 3 is separated from the circuit travel switch 7, and the circuit travel switch 7 gives a control signal to the power supply control mechanism 5, so that the power supply control mechanism 5 conducts the external power supply to the spring conductive coil 6 and the power supply circuit of the motor. The motor drives the wire winding wheel 8 to rotate and drive the wire rope 10 to be gradually released, and drives the spring seat 3 and the lamp mounting plate 4 to descend synchronously through the movable pulley 9, so as to adjust the height of the lamp. At this time, the lamp is always turned on and lit by the elastic force of the spring conductive coil 6. When the motor drives the wire winding wheel 8 to rotate in the opposite direction and wind the wire rope 10, the lamp gradually rises, and at this time, it can be stopped at a suitable height by a remote controller. When the lamp rises to the highest point, the boss 302 touches the circuit travel switch 7, and the circuit travel switch 7 feeds back to the power supply control mechanism 5, so that the power supply control mechanism 5 cuts off the power supply circuit of the spring conductive coil 6 and the motor, the lamp goes out, and the motor stops running.
