Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a self-limiting light-guiding and light-emitting lighting mechanism. Background Art

[0002] Traditionally, large-area light-emitting surfaces are realized by using LEDs and reflectors, which results in a strong granular lighting effect and a large number of LEDs. The use of a light-guiding structure can reduce the number of LEDs and make the light-emitting surface more uniform, ensuring the lighting effect while reducing the cost of the entire lamp. It is currently widely used. The light-guiding luminous lamps in the prior art are generally used in vehicle lighting technology. When light-guiding luminous lamps are installed on the vehicle frame, they are generally clamped, manually limited, and then bolted. The operation is cumbersome, so a self-limiting light-guiding luminous lighting mechanism is urgently needed. Utility Model Content

[0003] The purpose of the utility model is to provide a reasonably designed self-limiting light-guiding luminous lighting mechanism to solve the above technical problems in view of the defects and shortcomings of the prior art.

[0007] An extrusion block, after the extrusion block moves through the positioning slot, is inserted into the adjustment cavity, a compression spring is fixedly arranged between the extrusion block and the inner wall of the adjustment cavity; the position of the extrusion block is matched with the positioning block to be set in conflict;

[0008] A limit block, wherein the bottom of the limit block slides through the adjustment cavity and is embedded in the upper end of the limit column inserted in the positioning groove, and the lower end of the limit column is fixedly arranged on the top surface of the light-guiding luminous lamp body;

[0009] Connecting seats, there are two connecting seats, which are respectively fixed on the opposite surfaces of the extrusion block and the limit block, and the two ends of the adjusting rod are respectively slidably embedded in the waist-shaped grooves opened on the side walls of the connecting seat through the adjusting shaft, and the middle part of the adjusting rod is rotatably arranged inside the adjusting cavity through the rotating shaft and the bearing;

[0010] The secondary self-limiting mechanism is arranged on one side of the adjusting cavity and is connected to the limiting block.

[0011] As a further improvement of the utility model, guide blocks are symmetrically fixed on the two side walls of the extrusion block, and the guide blocks are slidably embedded in the guide grooves opened on the inner side walls of the adjustment cavity; the up and down movement of the extrusion block is limited and guided by the coordinated sliding of the guide blocks and the guide grooves.

[0012] As a further improvement of the present invention, a flange is integrally formed on the side edge of the bottom of the extrusion block, and the flange is set to limit the inner top surface of the positioning groove; the position of the extrusion block is limited by the setting of the flange.

[0013] As a further improvement of the utility model, an inclined surface is provided on the side wall of the extrusion block, and after the positioning block slides over the inclined surface, it is abutted against the bottom surface of the extrusion block; the setting of the inclined surface facilitates the extrusion block to be abutted into the adjustment cavity.

[0016] A return spring is fixedly arranged between the limit plate and the slot.

[0017] Through the above technical solution design, when the extrusion block is squeezed by the positioning block to move upward, the limit block is driven to move downward through the transmission action of the adjusting rod. Due to the reverse compression force of the reset spring, the limit rod is pressed against the side wall of the limit block until the limit block descends and is stuck on the end of the limit column. At this time, the limit rod is inserted into the limit hole to perform secondary limiting on the limit block, and then perform secondary limiting on the light-guiding luminaire body.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows: the self-limiting photoluminescent lighting mechanism described in the utility model can self-limit the photoluminescent lighting lamp before the photoluminescent lighting lamp bolts are installed, without the need for manual limiting, and the positioning is more accurate and more practical. The utility model has the advantages of reasonable setting and low production cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] It also contains:

[0028] Positioning blocks 3, there are several positioning blocks 3, and they are fixed on the top surface of the light-guiding luminous lamp body 1 by bolts. The positioning blocks 3 are slidably arranged in positioning grooves 4 opened in parallel on the bottom surface of the frame mounting plate 2 to initially limit the light-guiding luminous lamp body 1. An adjustment cavity 5 is opened in the frame mounting plate 2 on the upper side of the positioning groove 4;

[0029] Extrusion block 6, after the extrusion block 6 moves through the positioning groove 4, it is inserted into the adjustment cavity 5, and a compression spring 7 is fixed between the extrusion block 6 and the inner side wall of the adjustment cavity 5 by bolts; the position of the extrusion block 6 is matched with the positioning block 3 and is set in abutment; an inclined surface is provided on the side wall of the extrusion block 6, and the positioning block 3 is set on the bottom surface of the extrusion block 6 after sliding over the inclined surface; the setting of the inclined surface facilitates the extrusion block 6 to be set in the adjustment cavity 5; guide blocks 13 are symmetrically integrally formed on the two side walls of the extrusion block 6, and the guide blocks 13 are slidably embedded in the guide groove 14 provided on the inner side wall of the adjustment cavity 5; the up and down movement of the extrusion block 6 is limited and guided by the cooperation and sliding of the guide block 13 and the guide groove 14; a flange 15 is integrally formed on the side edge of the bottom of the extrusion block 6, and the flange 15 is set to limit the inner top surface of the positioning groove 4; the position of the extrusion block 6 is limited by the setting of the flange 15;

[0030] A limit block 8, wherein the bottom of the limit block 8 slides through the adjustment cavity 5 and is embedded in the upper end of a limit column 9 inserted in the positioning groove 4, and the lower end of the limit column 9 is fixedly arranged on the top surface of the light-guiding luminous lamp body 1;

[0031] The connecting seat 10 is two and fixedly arranged on the opposite surfaces of the extrusion block 6 and the limit block 8 respectively. The two ends of the adjusting rod 11 are respectively slidably embedded in the waist-shaped grooves opened on the side walls of the connecting seat 10 through the adjusting shaft 12. The middle part of the adjusting rod 11 is rotatably arranged inside the adjusting cavity 5 through the rotating shaft 17 and the bearing.

[0032] The secondary self-limiting mechanism 16 is arranged on one side of the adjusting chamber 5 and connected to the limiting block 8 .
