Description

Technical Field

[0001] The utility model relates to a field, in particular to a fixed fine-adjustable floodlight. Background Art

[0002] A floodlight is a lighting device that can project light to a specific location to illuminate the area. Existing floodlights are divided into small-range single-lamp lighting devices and large-range multi-lamp lighting devices. Since existing multi-lamp devices generally use a shell and a structure in which multiple lamps are fixedly arranged, it is impossible to adjust the lamps in the multi-lamp device, and the lighting range of the lamps is very limited. If the illumination of the multi-lamp device needs to be adjusted, the entire device needs to be disassembled, which is very inconvenient in some scenes with greater lighting effects. In addition, since the lighting position of traditional floodlights is unchanged, when adjusting the light, it is necessary to constantly move the floodlight to a suitable place and then realign it, which is very troublesome.

[0003] Therefore, the existing floodlights need to be further improved. Utility Model Content

[0004] In view of the above-mentioned prior art, the technology to be realized by the present invention is: to realize the fine-tuning function of multi-lamp floodlights, and to adjust the irradiation position of the light anytime and anywhere without moving the floodlight as a whole.

A spring top plate is fixed at the top of the side groove, and a spring is arranged between the top wall of the sliding rod and the bottom wall of the spring top plate. The sliding rod is inserted on each horizontal slider.

[0010] Furthermore, the second fine-tuning device in the utility model includes two grooves arranged on the horizontal sliding block, elastic support feet are hinged in the grooves, the two elastic support feet are clamped on the adjacent walls of the two grooves, a supporting platform for installing lamps is arranged on the elastic support feet, and two resistance-increasing patterns that can be used to increase the damping feeling are arranged on the adjacent walls of the elastic support feet and the grooves.

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0022] like Figures 1 to 5A fixed fine-adjustable floodlight is shown, comprising a housing 1 and a plurality of lamps 2 arranged therein, wherein a fine-adjustment device 1 3 for adjusting the lateral irradiation position of the lamp 2 and a fine-adjustment device 2 4 for adjusting the lateral swing angle of the lamp 2 are arranged inside the housing 1, and a general adjustment device 5 for adjusting the front irradiation angle of the lamp 2 is arranged at the bottom of the housing 1. A plurality of movable lamps are arranged inside the housing, and each lamp can be moved laterally on the housing through the fine-adjustment device 1 to adjust the interval position of the irradiation between each lamp, and the fine-adjustment device 2 can swing the position of the lamp to adjust the lateral angle of irradiation between each lamp, and the general adjustment device can adjust the longitudinal angle of the entire lamp, that is, the height angle of irradiation to the front. As the overall floodlight has excellent multi-directional adjustment capabilities, it can be fixedly placed, and there is no need to frequently move the entire translucent lamp due to the adjustment of the light irradiation position.

[0023] The housing 1 of the utility model comprises a bottom shell 11, a middle layer partition 12, and a top shell 13, wherein the top of the top shell 13 is a light-transmitting plate 14. The top shell can be opened from the bottom shell, and a hinged connection or a snap-on connection can be adopted to achieve the purpose of being switchable. After the top shell is opened, the lamp is exposed from the middle layer partition, and the user can adjust each lamp at this time. The middle layer partition is used to cover the bottom shell structure to make the interface simpler. The light-transmitting plate is used to allow the lamp to irradiate and transmit light.

[0024] The fine-tuning device 3 described in the utility model includes a plurality of transverse grooves 31 arranged on the bottom shell 11, and a transverse slider 32 is arranged in the transverse groove 31. The transverse groove allows the transverse slider to slide inside, and the length of the transverse groove is longer than the transverse slider, so that the transverse slider can slide a certain distance, and the distance is not limited and can be designed by yourself. The movement of the transverse slider is used to drive the lamp to move horizontally, thereby changing the distance between lamps. Users can adopt a variety of different lighting schemes, such as: conventional lighting schemes with uniformly spaced lamps, lighting schemes where two lamps are close to each other as a group, etc.

[0025] The fine-tuning device 3 described in the utility model also includes a resistance-increasing pattern 33 arranged at the bottom of the horizontal slider 32 and the bottom of the horizontal groove 31 for increasing the damping feeling. Side grooves 34 are arranged on the left and right sides of the bottom shell 11. A sliding rod 35 that can move up and down is arranged in the side grooves 34. A spring top plate 36 is fixed at the top of the side groove 34. A spring 37 is arranged between the top wall of the sliding rod 35 and the bottom wall of the spring top plate 36. The sliding rod 35 is inserted on each horizontal slider 32. The spring is linked between the fixed spring top plate and the movable sliding rod, so the spring can drive the sliding rod to press downward. When the horizontal slider is adjusted horizontally, due to the action of the spring and the resistance-increasing pattern 1, the user can obviously feel the damping feeling when adjusting. It is necessary to apply a certain force to move the horizontal slider to a certain distance to achieve the purpose of adjustment, and this position will not automatically shift when it is not subjected to a strong external force.

[0026] The fine-tuning device 2 4 described in the utility model includes two grooves 41 arranged on the horizontal slider 32, and elastic legs 42 are hinged in the grooves 41. The two elastic legs 42 are clamped on the adjacent walls of the two grooves 41. A support platform 43 on which the lamp 2 can be installed is arranged on the elastic legs 42, and resistance-increasing patterns 2 44 that can be used to increase the damping sense are arranged on the adjacent walls of the elastic legs 42 and the grooves 41. The elastic legs can be made of plastic material with a certain toughness, and the two elastic legs can be clamped on the two adjacent walls of the two grooves. Since the elastic legs are not hingedly connected, the elastic legs can rotate in a fan shape in the grooves, and determine the angle of the support platform and thus the illumination angle of the lamp. The damping sense is increased by the resistance-increasing patterns 2. A certain force needs to be applied to move the horizontal slider a certain distance to achieve the purpose of adjustment, and the position will not automatically shift when no strong external force is applied. Users can adopt a variety of different lighting solutions, such as: a conventional lighting solution with multiple lamps at perpendicular angles to each other, a lighting solution with two lamps as a group, close to or far away from each other to form an obtuse angle or an acute angle, etc.

[0027] The total adjustment device 5 in the utility model includes a bottom plate 51 hinged at the bottom of the bottom shell 11, and a resistance-increasing pattern 3 52 is provided at the hinge between the bottom plate 51 and the bottom shell 11. The bottom plate is hingedly connected to the bottom shell, so when the bottom plate is fixed to the ground, the bottom shell can rotate along the hinge point to change the longitudinal angle of all the lamps as a whole, thereby changing the angle of illumination. The resistance-increasing pattern 3 also requires a certain force to move the horizontal slider a certain distance to achieve the purpose of adjustment, and this position will not automatically shift when no strong external force is applied.

[0028] The resistance-increasing pattern 1 33 and the resistance-increasing pattern 3 52 in the present invention are both concave-convex straight strips arranged at intervals, and the resistance-increasing pattern 2 44 is a concave-convex straight strip arranged in a fan shape. That is, a plurality of straight strips are arranged on a plane to form a concave-convex regular surface. When two planes are displaced and moved relative to each other, the straight strips and the straight strips restrict each other to increase the damping feeling. After a strong force is applied, the force exceeds the force restricted by the straight strips and the two regular surfaces can still be displaced and moved.

[0029] The middle layer partition plate 12 of the present invention is provided with a position avoidance hole 6 for the arrangement of the position avoidance horizontal slide block.
