Description

Technical Field

[0001] This utility model relates to lighting fixtures, and in particular to a device that can be used for adjusting the front and rear of a lighting fixture. Background Technology

[0002] People use various types of lamps in their daily lives. Lamp fixtures can be categorized by light source (incandescent, halogen, LED, etc.) and by installation method (chandeliers, downlights, floor lamps, table lamps, etc.). Most lamps are fixed structures installed in walls or furniture, offering advantages such as not taking up floor space, high illumination height, and wide coverage, but they cannot be adjusted to meet user needs. Some lamps are adjustable, such as table lamps, where the lampshade's orientation can be adjusted by changing its position or bending the gooseneck tube; however, these adjustable lamps require significant desktop or floor space, are low to the ground, and their lighting effect is difficult to guarantee effectively. There are also some wall-mounted adjustable lamps, but their adjustment mechanisms are more complex, the positioning after adjustment is poor, and they are easily misaligned due to gravity or slight vibrations. Utility Model Content

[0003] The purpose of this utility model is to provide a device with a simple structure that can be installed on furniture or other equipment and can adjust the lamp back and forth, so as to simplify the structure and improve the convenience and stability of adjustment.

[0019] This utility model proposes a lamp adjustment device.

[0020] The lamp adjustment device of this embodiment includes an adjustment base 1 fixedly installed, an adjustment hole 11 horizontally arranged on the adjustment base, and an adjustment rod 2 installed on the adjustment base and moving along the adjustment hole. A lamp housing 3 is installed at one end of the adjustment rod, and a light source (such as a lamp board or light strip with LED beads) is installed on the lamp housing. A recessed platform 12 is provided on one side of the adjustment base, and a positioning groove 13 communicating with the adjustment hole is provided in the platform. A positioning block 4 made of rubber material is installed in the platform, and a friction part 41 is provided on the positioning block that passes through the positioning groove. The friction part contacts the adjustment rod.

[0021] like Figure 1 As shown, the adjustment base can be installed on a wall or other furniture or equipment. By pulling the adjustment rod along the adjustment hole of the adjustment base, the lamp housing and its light source can be adjusted forward and backward. Figure 2 As shown; and during the movement of the adjusting rod, the adjusting rod will continuously contact the friction part of the positioning block and generate relative movement. This can not only prevent the adjusting rod from moving too fast and causing a collision, but also provide a limit and fixation after the adjusting rod moves into place, so as to prevent the adjusting rod and the lamp housing from moving unexpectedly.

[0022] like Figures 1-4As shown in the figure, a clamping seat 5 of a "匚"-shaped structure is installed on an adjusting base 1, a screw rod 6 is screwed to the top of the clamping seat, one end of the screw rod is located above the clamping seat and connected with a rotating handle 7, and the other end of the screw rod is located in the clamping seat and connected with a pressing plate 8. A user holds the rotating handle and drives the screw rod to rotate, thereby adjusting the position of the screw rod, so that the pressing plate and the bottom of the clamping seat can be clamped and fixed on furniture or equipment, thereby forming detachable fixed installation; the installation structure is simple, convenient to operate, can be clamped and fixed on various furniture such as cabinets, tables, boards, and has wide applicability and small occupied space. The top of the adjusting base 1 is open, the clamping seat 5 is detachably installed on the top of the adjusting base through screws or screw rods, and the bottom surface of the clamping seat abuts against a positioning block 4. Besides further simplifying the structure, this can also adjust the pressure applied by the clamping seat to the positioning block, thereby changing the resistance of the positioning block to the adjusting rod, and ensuring the limiting strength of the positioning block to the adjusting rod while enabling the adjusting rod to move back and forth smoothly.

[0023] As Figure 4 , 5 shown in the figure, the inner wall of the adjusting hole 11 and the outer wall of the adjusting rod 2 are oppositely provided with a guide strip 14 and a guide groove 21 which are in concave-convex fit, and the direction of the guide strip and the guide groove is parallel to the moving direction of the adjusting rod 2, which can improve the moving accuracy and working stability of the adjusting rod. In addition, the direction of the positioning groove 13 is parallel to the moving direction of the adjusting rod 2, thereby increasing the contact area and the friction force applied to the adjusting rod, making the adjusting rod more stable after being moved in place.

[0024] In the lamp adjusting device described above, a control button 31 for controlling the operation of a light source is installed on a side of the lamp housing 3 facing away from the adjusting base 1, that is, a side facing the user, so as to facilitate user operation.

[0025] The above description is only a preferred embodiment of the present utility model, and is not intended to limit the patent scope of the present utility model. Any equivalent structural transformation made by using the description and drawings of the present utility model under the inventive concept of the present utility model, or direct / indirect application to other related technical fields, shall be included in the patent protection scope of the present utility model.
