Description

Technical Field

[0001] The utility model relates to the technical field of product display racks, in particular to a lighting device for a product display rack. Background Art

[0002] In the display and shooting of industrial products, artworks, etc., lighting devices are often used to improve the display effect or shooting effect of the products. Because the lighting angle of existing lighting devices is not adjustable or the degree of adjustment is limited, it is not possible to flexibly adjust the lighting angle according to factors such as the lighting environment of the exhibition hall, the shape and structural characteristics of the designed exhibits, and the impact of objects outside the exhibits on the surrounding environment, which can easily limit the improvement of the lighting effect of the exhibits. Moreover, for relatively large exhibits, it is necessary to arrange lighting lamps at multiple angles at different heights, which not only increases the cost, but also makes it difficult to achieve the ideal uniformity of the lighting effect. Utility Model Content

[0003] In order to overcome the above technical problems, the utility model provides a lighting device for a product display stand, whose lighting angle has a wide adjustment range. The lighting angle of the lighting device can be flexibly adjusted during the product display process, which helps to improve the lighting effect during the product display process.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a product display stand lighting device, including a stand body, a reflector, a lighting unit and a fixing part. The stand body includes a base and a vertical plate fixed to the right side of the base, and the reflector is arranged on the upper part of the vertical plate. On the base, a slide groove is formed at the left position close to the lower end of the vertical plate. A linear groove extending in the vertical direction is formed at the lower part of the vertical plate.

[0005] The lighting unit includes a carrier, a plurality of lamp beads distributed on the carrier, and a controller fixed on the carrier. A pivot is provided at the lower end of the carrier and the pivot can match with a slide groove provided on the base, so that the lower end of the carrier can move back and forth in a straight line relative to the base in the left and right directions.

[0006] The fixing part includes an inner rod, an outer rod and a nut, and an axial through hole is formed on the outer rod. Both ends of the inner rod extend out of the through hole of the outer rod, and a ball block is arranged on the left end of the inner rod. A groove for accommodating the ball block is arranged on the support frame, and a cover plate is arranged at the end of the groove to confine the ball block in the groove, so that the outer rod can move in space relative to the support frame.

[0007] A threaded countersunk hole is formed at the left end of the through hole of the outer rod, and an external threaded surface 1 matching the threaded countersunk hole is formed on the left outer wall of the inner rod. By screwing the right end of the inner rod or the right end of the outer rod, the matching length of the external threaded surface 1 and the threaded countersunk hole can be adjusted, and the length of the inner rod on the left side of the vertical plate can be adjusted.

[0008] The outer rod passes through the linear groove and a radial flange is formed at the left end of the outer rod, so that the outer diameter of the flange is larger than the groove width of the linear groove, so that the left end of the outer rod cannot pass through the linear groove.

[0009] An external thread section matching the nut is formed at least on the outer wall of the right end of the outer rod. Screwing the nut can switch the outer rod between a state of being fixedly connected to the vertical plate and a state of being relatively movable with the vertical plate.

[0010] Optionally, a support platform is further included and the support platform is matched with the base through a pivot structure, so that the support platform can rotate around a vertical axis relative to the base.

[0011] Optionally, the reflective plate is hingedly matched with the upper portion of the vertical plate, so that the reflective plate can be flipped upward and downward relative to the vertical plate, and the angle formed by the reflective plate relative to the horizontal plane can be adjusted.

[0012] A locking portion is provided between the reflector and the vertical plate, and the locking portion can selectively switch the reflector between a fixed state relative to the vertical plate and a state capable of flipping relative to the vertical plate.

[0013] Optionally, the locking portion includes a roller portion and a rope.

[0014] A rivet post is arranged at the left end of the reflective plate and one end of the rope is fixed on the rivet post.

[0015] The rotating roller part is fixed on the top of the vertical plate, and comprises a roller with a radial flange formed at the lower end and a rotating block with an insertion rod formed at the lower end.

[0016] The radial flange on the roller is inserted into the sink groove formed on the top surface of the vertical plate, and a cover is fixedly provided at the upper end of the sink groove. The cover can prevent the radial flange from moving upward. The cover is fixed to the top surface of the vertical plate by bolts.

[0017] The other end of the rope is fixed on the roller and when the roller rotates around the vertical axis relative to the vertical plate, the rope can be wound around the wall of the roller and can be released from the roller.

[0018] The insert rod on the rotary block matches the cylinder cavity of the roller, so that the rotary block can move up and down in the vertical direction relative to the roller.

[0019] A prismatic countersunk hole is formed at the lower end of the rotary block, and a plurality of insert arms are formed around the circumference of the prismatic countersunk hole. A slot corresponding to the insert arm is provided on the cover, and the insert arm can prevent the rotary block from rotating around the vertical axis after being inserted into the slot.

[0020] When the rotary block moves upward relative to the roller until the lower end of the insertion rod corresponds to the upper part of the cylinder cavity of the roller, screwing the rotary block can cause the roller to rotate around the vertical axis.

[0021] When the rotary block moves downward relative to the roller until the lower end of the insertion rod corresponds to the lower part of the roller cavity and the insertion arm is inserted into the slot, the prismatic countersunk hole can be plugged and matched with the prismatic surface formed at the upper end of the roller, thereby preventing the roller from rotating around the vertical axis.

[0022] Optionally, a first inner cylinder and a second inner cylinder are fixedly provided in the cylinder cavity of the roller.

[0023] The inner cavity of the second inner cylinder is a prism hole, and correspondingly, a prism section is formed at the lower part of the insertion rod to match the prism hole.

[0024] The inner cavity of the first inner cylinder is a circular hole and the inner diameter of the first inner cylinder is greater than the inner diameter of the second inner cylinder.

[0025] An axial flange is formed on the upper end of the second inner cylinder and extends upward relative to the upper end of the roller. The outer wall of the axial flange is formed into a prismatic surface that can correspond to and match the prismatic countersunk hole.

[0026] Optionally, the lower end of the roller is formed into a spherical surface that protrudes axially downward.

[0027] The beneficial effect of the utility model is that the lighting angle of the lighting device of the product display stand involved in this patent has a wide adjustment range, and the lighting angle of the lighting device can be flexibly adjusted during the product display process, so that the lighting light shines downward from the upper part of the product, which helps to make the lighting light cover the product in a soft and more uniform state, and helps to improve the lighting effect during the product display process.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0033] like Figures 1 to 3 The product display stand lighting device shown in the figure includes a stand body 10 , a support table 20 , a reflector 30 , a lighting unit 40 , a fixing part 50 and a roller part 60 .

[0034] The frame body 10 includes a base 11 and a vertical plate 12 fixed to the right side of the base 11. A slide groove 111 is formed on the base 11 at a left position close to the lower end of the vertical plate 12. A linear groove 121 extending in the vertical direction is formed at the lower part of the vertical plate 12.

[0035] The support platform 20 is matched with the base through a pivot structure and is correspondingly arranged on the left side of the base 11. The support platform 20 can rotate around a vertical axis relative to the base 11. Exhibits are placed on the upper end surface of the support platform 20 and can rotate synchronously with the rotation of the support platform 20 relative to the base 11.

[0036] The reflective plate 30 is hingedly disposed on the upper end of the vertical plate 12 .

[0037] The lighting unit 40 includes a carrier, a plurality of lamp beads distributed on the carrier, and a controller fixed on the carrier. A pivot is provided at the lower end of the carrier and the pivot can match the slide slot 111 provided on the base 11, so that the lower end of the carrier can move back and forth in a straight line relative to the base 11 in the left and right directions, and the lighting unit 40 or the lower end of the carrier can move relative to the base 11 in the left and right directions to adjust the angle formed by the carrier relative to the horizontal plane.

[0038] The fixing portion 50 includes an inner rod 51, an outer rod 52 and a nut 53. A through hole (or shaft hole) is formed in the outer rod 52 along its axial direction. The inner rod 51 is longer than the outer rod 52 and both ends of the inner rod 51 are kept in a state of extending out of the through hole on the outer rod 52.

[0039] A ball block 511 is provided on the left end of the inner rod 51. A groove for accommodating the ball block 511 is provided on the carrier, and a cover plate is provided at the end of the groove to confine the ball block 511 in the groove, so that the inner rod 51 can rotate around its axis in space relative to the carrier. In this way, when the carrier is at different angles relative to the horizontal plane, the direction of the inner rod 51 relative to the horizontal plane can be adjusted so that the axis of the inner rod 51 is consistent with the horizontal direction as much as possible.

[0040] A threaded countersunk hole 522 is formed at the left end of the through hole of the outer rod 52, and an external threaded surface 1 512 matching the threaded countersunk hole 522 is formed on the left outer wall of the inner rod 51. By screwing the right end of the inner rod 51 or the right end of the outer rod 52, the matching length between the external threaded surface 1 512 and the threaded countersunk hole 522 can be adjusted, and the length of the inner rod 51 on the left side of the vertical plate 12 can be adjusted.

[0041] The outer rod 52 passes through the linear groove 121 and a radial flange 521 is formed at the left end of the outer rod 52, so that the outer diameter of the flange 521 is larger than the groove width of the linear groove 121, so that the left end of the outer rod 52 cannot pass through the linear groove 121, so that the left end of the outer rod 52 can be kept in the state of being on the vertical plate 12 or on the left side of the linear groove 121. The flange 521 can be an annular flange extending radially outward.

[0042] An external thread section matching the nut 53 is formed on the right side of the outer wall of the outer rod 52, and the outer diameter of the external thread section can be smaller than the groove width of the linear groove 121. The outer diameter of a section of the outer rod 52 corresponding to the linear groove 121 is made consistent with the groove width of the linear groove 121. By screwing the nut 53, the outer rod 52 can be switched between a state of being fixedly connected to the vertical plate 12 and a state of being relatively movable with the vertical plate 12.

[0043] The reflector 30 is hingedly matched with the upper part of the vertical plate 12, so that the reflector 30 can be flipped upward and downward relative to the vertical plate 12, and the angle formed by the reflector 30 relative to the horizontal plane can be adjusted to adjust the lighting angle.

[0044] A locking portion is provided between the reflector 30 and the upright plate 12 . The locking portion can selectively switch the reflector 30 between a fixed state relative to the upright plate 12 and a state in which the reflector 30 can be flipped relative to the upright plate 12 .

[0045] like Figures 1 to 3 As shown, the locking portion includes a roller portion 60 and a rope 70 .

[0046] A rivet post 31 is provided at the left end of the reflector 30 and one end of the rope 70 is fixed to the rivet post 31 .

[0047] The roller portion 60 is fixed on the top of the vertical plate 12 and includes a roller 61 with a radial flange 611 formed at the lower end and a rotary block 65 with an insertion rod 651 formed at the lower end.

[0048] The radial flange 611 on the roller 61 is inserted into the recessed groove 123 formed on the top surface of the vertical plate 12, and a cover 62 is fixedly provided at the upper end of the recessed groove 123. The cover 62 can prevent the radial flange 611 from moving upward. The cover 62 is fixed to the top surface of the vertical plate 12 by bolts.

[0049] The other end of the rope 70 is fixed on the roller 61 and when the roller 61 rotates around the vertical axis relative to the vertical plate 12, the rope 70 can be wound around the wall of the roller 61 and can be released from the roller 61.

[0050] The insert rod 651 on the rotary block 65 matches the cylinder cavity of the roller 61 , so that the rotary block 65 can move up and down relative to the roller 61 in the vertical direction.

[0051] A prismatic counterbore 653 is formed at the lower end of the rotary block 65, and a plurality of insert arms 654 are formed around the circumference of the prismatic counterbore 653. A slot 621 corresponding to the insert arm 654 is provided on the cover 62, and the insert arm 654 can prevent the rotary block 65 from rotating around the vertical axis after being inserted downward into the slot 621.

[0052] When the rotary block 65 moves upward relative to the roller 61 until the lower end of the insertion rod 651 corresponds to the upper part of the cylinder cavity of the roller 61, screwing the rotary block 65 can cause the roller 61 to rotate around the vertical axis.

[0053] When the rotary block 65 moves downward relative to the roller 61 until the lower end of the insertion rod 651 corresponds to the lower part of the cylinder cavity of the roller 61 and the insertion arm 654 is inserted into the slot 621, the prismatic countersunk hole 653 can be plugged and matched with the prismatic surface formed at the upper end of the roller 61 (in the illustrated scheme, formed at the upper end of the outer peripheral surface of the axial flange 642 shown in the figure), thereby preventing the roller 61 from rotating around the vertical axis and tightening the rope 70 to keep the reflector 30 at a certain tilt angle relative to the horizontal plane.

[0054] Specifically, a first inner cylinder 63 and a second inner cylinder 64 are fixedly disposed in the cylinder cavity of the roller 61, and the second inner cylinder 64 is located directly above the first inner cylinder 63. The inner cavity of the second inner cylinder 64 is a prism hole 641, and correspondingly, a prism section 652 is formed at the lower part of the insertion rod 651 to (optionally) match the prism hole 641.

[0055] The inner cavity of the first inner cylinder 63 is a circular hole and the inner diameter of the first inner cylinder 63 is larger than the inner diameter of the second inner cylinder 64. Thus, when the prism section 652 of the insert rod 651 moves relative to the roller 61 to the upper part of the cylinder cavity of the roller 61, the prism section 652 can correspond to the prism hole 641, and at this time, the roller 61 can be rotated around the vertical axis by screwing the rotary block 65. When the prism section 652 of the insert rod 651 moves relative to the roller 61 to the lower part of the cylinder cavity of the roller 61, the prism section 652 can correspond to the axial hole of the first inner cylinder 63, because a radial spacing is formed between the outer wall of the prism section 652 and the inner wall of the first inner cylinder 63, screwing the rotary block 65 will not drive the roller 61 to rotate. It is required that the axial length of the first inner cylinder 63 (or the axial hole height of the first inner cylinder 63) is greater than the axial length (prism surface) of the prism section 652. In this way, when the prism section 652 moves downward to the upper part of the axial hole of the first inner cylinder 63 (at this time, the lower end of the insert arm 654 has not been inserted into the slot 621 or there is still a vertical distance between the lower end of the insert arm 654 and the upper end surface of the cover 62), the rotary block 65 can be rotated to adjust each of the insert arms 654 on it to correspond to the upper part of each slot 621, and the roller 61 will not be driven to rotate around the vertical axis relative to the vertical plate 12. After each of the insert arms 654 corresponds to the upper part of each slot 621, the prism section 652 is continued to move downward relative to the first inner cylinder 63, so that the lower end of the insert arm 654 is inserted into the slot 621, so that the rotary block 65 and the roller 61 can be prevented from rotating around the vertical axis relative to the vertical plate 12.

[0056] An axial flange 642 is formed at the upper end of the second inner cylinder 64 and the axial flange 642 extends upward relative to the upper end of the roller 61. The outer wall of the axial flange 642 is formed as a prismatic surface that can correspond to and match the prismatic counterbore 653.

[0057] The lower end of the roller 61 is formed into a spherical surface protruding axially downward, so that a point-to-surface matching relationship is formed between the lower end of the roller 61 and the inner bottom surface of the sink 123, which helps to reduce the friction resistance when the roller 61 rotates relative to the vertical plate 12.

[0058] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. The present invention can be improved in many aspects without violating the overall concept, and those familiar with the technology can modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical concept disclosed by the present invention should still be covered by the claims of the present invention.
