Description

Technical Field

[0001] The invention relates to the field of lamp installation, and in particular to a display cabinet pole lamp installation structure. Background Art

[0002] The background technology of display cabinet pole lights is an indispensable and important part of modern commercial display design. With the increasing competition in the business environment and the improvement of consumers' requirements for shopping experience, the lighting design of display cabinets is no longer limited to basic lighting functions, but pays more attention to how to enhance the attractiveness of products through lighting effects and enhance customers' shopping experience. Pole lights are a common lighting form in display cabinets. Their background technology integrates knowledge from multiple fields such as optics, electronics, materials science, and design aesthetics. First of all, in the selection of light sources, modern pole lights generally use LED technology. This light source has the advantages of high energy efficiency, long life, and environmental protection. It can meet the needs of supermarket display cabinets to be continuously opened for a long time, while reducing energy consumption and operating costs. When installing existing display cabinet pole lamps, a common method is to tightly embed an I-shaped ring-shaped black rubber plug into a preset groove of the display cabinet, and then insert the display cabinet pole lamp into the through hole in the center of the rubber plug. Its stability mainly depends on the friction between the outer wall of the pole lamp and the inner wall of the rubber plug through hole. However, when the staff needs to adjust the height of the display cabinet pole lamp, they must overcome this friction, which is more laborious. In addition, after repeatedly pulling and moving the display cabinet pole lamp, the rubber plug may face the risk of deformation, which will not only weaken the fixing effect of the rubber plug on the pole lamp, but also may cause the pole lamp to tilt, thereby affecting its normal use and display effect.

An annular slide plate 22 is rotatably connected to the top of the shell 1, and an inclined groove 23 is provided on the top of the annular slide plate 22, and the positioning rod 21 is located in the inclined groove 23. After the shell 1 is fixed, the installer can twist the annular slide plate 22.

[0035] Further, a first bevel gear 37 is welded on the outer peripheral wall of each threaded rod 12, a ring plate 2 38 is welded on the inner wall of the housing 1, and a plurality of mounting plates 2 39 are welded on the top of the ring plate 2 38. A threaded rod 2 40 is rotatably connected between each two mounting plates 2 39, and a second bevel gear 41 is welded on the outer wall of one side of each threaded rod 2 40. Each second bevel gear 41 is respectively meshed with each first bevel gear 37, and a threaded block 42 is threadedly connected on the outer peripheral wall of each threaded rod 2 40. The two mounting plates A limiting rod 2 60 is welded between the two 39, and the threaded block 42 is slidably set on the limiting rod 2 60. The set limiting rod 2 60 can limit the threaded block 42 during the movement process; a mounting frame 2 43 is welded on the top of each threaded block 42, and a sliding rod 3 44 is welded on the outer wall of each mounting frame 2 43. A sliding block 3 45 is slidably set on the outer peripheral wall of each sliding rod 3 44, and a spring 57 is slidably set on the outer peripheral wall of the sliding rod 3 44. The spring 57 is connected to the sliding block 3 45 and the outer peripheral wall of the mounting frame 2 43. The top of each slider 45 is welded with an abutment plate 46, and the rotating threaded rod 12 drives the first bevel gear 37 to rotate, and the first bevel gear 37 drives the second bevel gear 41 and the threaded rod to rotate, and the second threaded rod drives the threaded block 42, the mounting frame 2 43, the slide bar 3 44, the slider 3 45 and the abutment plate 46 to move, so that the abutment plate 46 abuts against the inner circumferential wall of the preset groove 59 opened on the display cabinet 58; the outer wall of the mounting frame 2 43 is welded with a linear slide rail 48, and the slider 3 45 A linear slider 49 is welded to the bottom and is slidably arranged in the linear slide rail 48. The linear slide rail 48 and the linear slider 49 can limit the slider three 45 during the movement; a tooth plate 47 is welded to the top of each abutment plate 46, and each tooth plate 47 is respectively engaged with each tooth block 35. The installer releases the pressure rod 25, and the connecting plate 29, the mounting frame 33 and the tooth block 35 are reset obliquely downward along the direction of the oblique rod 28. During this process, the tooth block 35 is re-engaged with the tooth plate 47.

[0036] Working principle: During installation, the housing 1 is placed in the preset slot 59 provided on the display cabinet 58, and then the installer uses two fingers of the left hand to push the pressure rod 25 to move into the inner cavity of the housing 1, and the pressure rod 25 drives the circular plate 26 to move, and the circular plate 26 pulls the pull rope 32 to move, and the pull rope 32 pulls the pull ring 31, the connecting plate 29 and the tooth block 35 to move obliquely upward along the inclined rod 28, so that the tooth block 35 is separated from the tooth plate 47, and then the contact tooth block 35 limits the position of the tooth plate 47;

[0037] Then, while the installer keeps pressing the pressure rod 25, he twists the worm 3 to rotate, and the worm 3 drives the worm wheel 6, the rotating rod 14 and the gear 17 to rotate, and the gear 17 drives the ring gear 5 to rotate, and the ring gear 5 drives the gear 2 10, the rotating rod 2 9, the universal joint 11 and the threaded rod 12 to rotate, and the threaded rod 12 drives the C-type plate 13 to move upward, and the C-type plate 13 drives the clamping plate 15 to move upward. Because the clamping plate 15 abuts against the inclined plate 16, and the contact between the clamping plate 15 and the inclined surface is an inclined surface, the clamping plate 15 will move along the inclined surface of the inclined plate 16 toward the outside of the shell 1 during the upward movement. As the clamping plate 15 continues to move upward, the top of the clamping plate 15 abuts against the top of the inner cavity of the display cabinet 58, thereby keeping the shell 1 stable in the vertical direction. Fig.12 As shown;

[0038] At the same time, the rotating threaded rod 12 will drive the first bevel gear 37 to rotate, the first bevel gear 37 drives the second bevel gear 41 and the threaded rod to rotate, and the second threaded rod drives the threaded block 42, the second mounting frame 43, the third slide bar 44, the third slide block 45 and the abutment plate 46 to move, so that the abutment plate 46 abuts against the inner circumferential wall of the preset groove 59 opened on the display cabinet 58, and then the installer releases the pressure rod 25, and the set connecting plate 29, the first mounting frame 33 and the tooth block 35 are reset obliquely downward along the direction of the inclined rod 28. In this process, the set tooth block 35 is re-engaged with the tooth plate 47, so that the tooth block 35 resumes the limit fixation of the tooth plate 47 and the abutment plate 46, and the abutment rod in a stable state keeps the shell 1 stable in the horizontal direction;

[0039] It should be noted that the elastic force of the spring five 57 is greater than that of the spring three 30, and the elastic force of the spring three 30 is greater than that of the spring four 36. The tooth block 35 is slidably arranged on the slide rod two 34. When the tooth block 35 is reset obliquely downward along the oblique rod 28, the tooth block 35 can be adaptively fine-tuned left and right, so that the tooth block 35 can be smoothly plugged into the tooth plate 47.

[0040] This device drives the clamping plate 15 to move upward by twisting the worm 3, so that the clamping plate 15 can fix the shell 1 on the display cabinet 58 with different wall thicknesses. At the same time, the worm 3 can drive the abutment plate 46 to move horizontally, and the abutment plate 46 is slidably set on the slide bar 3 44. When the aperture of the preset slot is small, the abutment plate 46 can be adaptively contracted along the slide bar 3 44, so that the abutment plate 46 can abut on the inner wall of the preset slot with different apertures, and the set tooth block 35 can be inserted into the tooth plate 47 to limit and fix the tooth plate 47, so that the abutment plate 46 can fix the shell 1 at the center of the preset slot with different apertures. The shell 1 can be fixed in the preset slot body 59 with different wall thicknesses and different apertures within a certain range by the clamping plate 15 and the abutment plate 46, which expands the scope of use of the device to a certain extent.

[0041] After the shell 1 is fixed, the installer can twist the annular slide plate 22. Since the positioning rod 21 is located in the inclined groove 23 of the annular slide plate 22, when the annular slide plate 22 rotates, the positioning rod 21 will move away from the center of the shell 1. At the same time, the positioning rod 21 will drive the clamping block 19 to move, so that the clamping block 19 disengages from the clamping groove 24, thereby releasing the limiting fixation of the clamping block 19 on the main body 2 of the pole lamp. At this time, the installer can freely adjust the height of the main body 2 of the pole lamp more easily.
