Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to a deformable lampshade. Background Technology

[0002] Currently, the lampshades available on the market are usually limited to a fixed shape, which not only gives people a rigid and boring feeling, but also cannot change the brightness and range of the light bulb by changing the shape of the lampshade according to the user's needs.

[0003] See patent document CN 106122895 A, which discloses a decorative deformable lampshade and a lamp fixture including the lampshade. The lampshade includes a bracket for installing and removing a handle or support rod, an outer cover disposed on the outside of the bracket, consisting of multiple thin plates continuously connected to form a honeycomb or plate shape, and whose shape can be freely changed by rotating up and down, a cover plate serving as a support frame for the outer cover and whose shape can be changed by its operation, a ring connector for inserting and securing the outer cover and cover plate, which is circular in shape so as to fold or unfold the outer cover by rotating the cover plate and whose diameter is variable, and a connecting rod for moving the ring connector up and down, one end of which is rotatably connected to the bracket and the other end of which is connected to the ring connector. However, the technical problems with the deformable lampshade disclosed in patent document CN 106122895 A are: 1) It requires the setting of operating handles, ring connectors, connecting rods, rotating parts and other driving components to drive the thin plate to rotate, which is complex in structure, cumbersome in assembly and expensive; 2) It requires a handle to be inserted into the lampshade to be used, and it is inconvenient to adjust the rotation of the thin plate. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a deformable lampshade that is simple in structure, easy to assemble, low in cost, and easy to operate by deforming the lampshade deformation strip, in order to overcome the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a deformable lampshade, comprising a first lampshade fixing ring, a second lampshade fixing ring, a support frame, a first pull rope, a second pull rope, and a plurality of lampshade deformation strips.

The plurality of lampshade deformation strips are arranged sequentially and spaced apart along the outer periphery of the first lampshade fixing ring and the second lampshade fixing ring. One end of the lampshade deformation strip is inserted into the corresponding first deformation strip fixing groove, and the other end of the lampshade deformation strip is inserted into the corresponding second deformation strip fixing groove; the inner circumference of the second lampshade fixing ring is provided with a support frame positioning slot, and the support frame is engaged with the support frame positioning slot; the first lampshade fixing ring is provided with a pull rope fixing mechanism, and the second lampshade fixing ring is provided with a first pull rope through hole and a second pull rope through hole, the first pull rope through hole and the second pull rope through hole have a set distance, one end of the first pull rope passes through the first pull rope through hole and is connected to the pull rope fixing mechanism, and one end of the second pull rope passes through the second pull rope through hole and is connected to the pull rope fixing mechanism.

[0006] Preferably, the inner circumference of the second lampshade fixing ring is provided with an upwardly extending positioning ring, and the upper outer side of the positioning ring is provided with a plurality of anti-loosening hooks; the inner circumference of the first lampshade fixing ring is movably fitted onto the outer side of the positioning ring, and the anti-loosening hooks hook onto the upper side of the inner circumference of the first lampshade fixing ring.

[0007] Preferably, a damping gear is provided on one side of the inner circumference of the first lampshade fixing ring, and a plurality of dampers that contact the damping gear are provided on one side of the positioning ring of the second lampshade fixing ring. When the first lampshade fixing ring and the second lampshade fixing ring rotate relative to each other, the damping gear and the plurality of dampers engage in damping cooperation.

[0008] Preferably, three damper slots are provided at equal intervals on one side of the positioning ring of the second lampshade fixing ring, and the number of dampers is three, with the dampers installed on the corresponding damper slots.

[0009] Preferably, the lampshade deformation strip includes an upper deformation strip and a lower deformation strip that are integrally connected to each other. The upper and lower deformation strips are respectively provided with a plurality of hinges for bending deformation. The connection between the upper and lower deformation strips also has a plurality of hinges for bending deformation. The hinges are integrally connected to the upper and lower deformation strips.

[0010] Preferably, the end of the upper deformable strip is provided with an upper connector that is inserted into the fixing groove of the first deformable strip, and the end of the lower deformable strip is provided with a lower connector that is inserted into the fixing groove of the second deformable strip.

[0011] Preferably, the upper circumferential side of the first lampshade fixing ring is provided with 30-40 first deformation strip fixing grooves at equal intervals, and the lower circumferential side of the second lampshade fixing ring is provided with 30-40 second deformation strip fixing grooves at equal intervals. The number of lampshade deformation strips is 30-40, and the number of the first deformation strip fixing grooves, the second deformation strip fixing grooves and the number of lampshade deformation strips are matched.

[0012] Preferably, the support frame includes a bulb mounting ring and three "<"-shaped support frames. The bulb mounting ring is used to mount the bulb. The upper end of each "<"-shaped support frame is connected to the bulb mounting ring, and a connecting ear is provided in the middle of the "<"-shaped support frame. The support frame has three positioning slots, which are equally spaced on the inner circumference of the second lampshade fixing ring. The connecting ear of each "<"-shaped support frame is inserted into the corresponding positioning slot. The support frame also includes a pull rope guide ring. The bulb mounting ring is located above the pull rope guide ring, and the lower end of each "<"-shaped support frame is connected to the pull rope guide ring. The other ends of the first and second pull ropes pass downwards through the pull rope guide ring, and pendants are connected to the other ends of the first and second pull ropes, respectively.

[0013] Preferably, the lampshade deformation strip is any one of a metal lampshade deformation strip, a plastic lampshade deformation strip, or a wooden lampshade deformation strip.

[0014] The beneficial effects of this invention are as follows: This invention includes a first lampshade fixing ring, a second lampshade fixing ring, a support frame, a first pull rope, a second pull rope, and multiple lampshade deformation strips. The overall components are few, and the structure is relatively simple. The first lampshade fixing ring is installed on the upper side of the second lampshade fixing ring. Multiple lampshade deformation strips are arranged sequentially and at intervals along the outer periphery of the first and second lampshade fixing rings. One end of each lampshade deformation strip is inserted into a corresponding first deformation strip fixing groove of the first lampshade fixing ring, and the other end of each strip is inserted into a corresponding second deformation strip fixing groove of the second lampshade fixing ring. One end of the first pull rope passes through a first pull rope through-hole and is connected to a pull rope fixing mechanism. One end of the second pull rope passes through a second pull rope through-hole and is connected to a pull rope fixing mechanism. Installation is easy; when the user pulls the first cord, the first lampshade fixing ring rotates clockwise relative to the second lampshade fixing ring, and the second lampshade fixing ring rotates counterclockwise relative to the first lampshade fixing ring. This forces the spacing between the two ends of the multiple lampshade deformation strips to change, causing the multiple lampshade deformation strips to undergo the first type of deformation together, such as unfolding outwards. When the user pulls the second cord, the first lampshade fixing ring rotates counterclockwise relative to the second lampshade fixing ring, and the second lampshade fixing ring rotates clockwise relative to the first lampshade fixing ring. This forces the spacing between the two ends of the multiple lampshade deformation strips to change, causing the multiple lampshade deformation strips to undergo the second type of deformation together, such as retracting inwards. Therefore, the user only needs to pull the first cord and the second cord separately to control the deformation of the multiple lampshade deformation strips, making operation convenient.

[0023] The structural and working principles of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1-8 As shown, the present invention is a deformable lampshade, characterized in that it includes a first lampshade fixing ring 1, a second lampshade fixing ring 2, a support frame 3, a first pull rope 4, a second pull rope 5, and a plurality of lampshade deformable strips 6. The first lampshade fixing ring 1 is installed on the upper side of the second lampshade fixing ring 2, and the first lampshade fixing ring 1 and the second lampshade fixing ring 2 are rotatably connected to each other. A plurality of first deformable strip fixing grooves 11 are circumferentially spaced on the upper side of the first lampshade fixing ring 1, and a plurality of second deformable strip fixing grooves 21 are circumferentially spaced on the lower side of the second lampshade fixing ring 2. The plurality of lampshade deformable strips 6 are arranged sequentially and spaced along the outer periphery of the first lampshade fixing ring 1 and the second lampshade fixing ring 2, and one end of the lampshade deformable strip 6 is connected to the corresponding... The first deformable strip fixing groove 11 is inserted into the lampshade, and the other end of the lampshade deformable strip 6 is inserted into the corresponding second deformable strip fixing groove 21; the inner circumference of the second lampshade fixing ring 2 is provided with a support frame positioning slot 22, and the support frame 3 is engaged with the support frame positioning slot 22; the first lampshade fixing ring 1 is provided with a pull rope fixing mechanism 12, and the second lampshade fixing ring 2 is provided with a first pull rope through hole 23 and a second pull rope through hole 24 in the radial direction. The first pull rope through hole 23 and the second pull rope through hole 24 have a set distance. One end of the first pull rope 4 passes through the first pull rope through hole 23 and is connected to the pull rope fixing mechanism 12. One end of the second pull rope 5 passes through the second pull rope through hole 24 and is connected to the pull rope fixing mechanism 12.

[0025] This invention has fewer overall components, a simpler structure, and is easy to assemble. When the user pulls the first pull cord 4, the first lampshade fixing ring 1 rotates clockwise relative to the second lampshade fixing ring 2, and the second lampshade fixing ring 2 rotates counterclockwise relative to the first lampshade fixing ring 1. This forces a change in the spacing between the two ends of the multiple lampshade deformation strips 6, causing the multiple lampshade deformation strips 6 to undergo a first type of deformation together, for example, unfolding outwards. (See [reference]). Figure 1 When the user pulls the second pull cord 5, the first lampshade fixing ring 1 rotates counterclockwise relative to the second lampshade fixing ring 2, and the second lampshade fixing ring 2 rotates clockwise relative to the first lampshade fixing ring 1. This forces the spacing between the two ends of the multiple lampshade deformation strips 6 to change, causing the multiple lampshade deformation strips 6 to undergo a second type of deformation together, such as tucking inwards. (See [link]). Figure 2 Therefore, users only need to pull the first pull rope 4 and the second pull rope 5 respectively to control the deformation of multiple lampshade deformation strips 6, which is convenient to operate.

[0026] like Figures 3-5 As shown, the inner circumference of the second lampshade fixing ring 2 is provided with an upwardly extending positioning ring 25, and the outer side of the upper end of the positioning ring 25 is provided with several anti-loosening hooks 26; the inner circumference of the first lampshade fixing ring 1 is movably fitted onto the outer side of the positioning ring 25, and the anti-loosening hooks 26 hook onto the upper side of the inner circumference of the first lampshade fixing ring 1. In this way, when installing the first lampshade fixing ring 1 onto the second lampshade fixing ring 2, it is only necessary to press the first lampshade fixing ring 1 downwards so that the anti-loosening hooks 26 hook onto the upper side of the inner circumference of the first lampshade fixing ring 1 to complete the installation, which is simple.

[0027] like Figures 5-8 As shown, a damping gear 13 is provided on one side of the inner circumference of the first lampshade fixing ring 1, and several dampers 27 in contact with the damping gear are provided on one side of the positioning ring 25 of the second lampshade fixing ring 2. When the first lampshade fixing ring 1 and the second lampshade fixing ring 2 rotate relative to each other, the damping gear 13 and the several dampers 27 engage in damping cooperation. When the first pull rope 4 or the second pull rope 5 is pulled, the rotation of the first lampshade fixing ring 1 and the second lampshade fixing ring 2 is affected by the damping gear 13 and the dampers 27; when the first pull rope 4 or the second pull rope 5 is stopped, the first lampshade fixing ring 1 and the second lampshade fixing ring 2 will stop rotating and be positioned, thereby ensuring that the multiple lampshade deformation strips 6 can be properly positioned after deformation. Preferably, three damper slots 271 are provided at equal intervals on one side of the positioning ring 25 of the second lampshade fixing ring 2, and the number of dampers 27 is three. The dampers 27 are installed on the corresponding damper slots 271.

[0028] like Figures 1-4 As shown, the lampshade deformable strip 6 includes an upper deformable strip 61 and a lower deformable strip 62 integrally connected to each other. Each of the upper and lower deformable strips has a plurality of hinges 63 for bending and deformation. The connection between the upper and lower deformable strips 61 and 62 also has a plurality of hinges 63 for bending and deformation. Each hinge 63 is carefully designed to be bent and deformed freely.

[0029] like Figures 1-4 As shown, the end of the upper deformable strip 61 is provided with an upper connector 64 that is inserted into the first deformable strip fixing groove 11, and the end of the lower deformable strip 62 is provided with a lower connector 65 that is inserted into the second deformable strip fixing groove 21. In this way, the lampshade deformable strip 6 can be inserted into or removed from the first lampshade fixing ring 1 and the second lampshade fixing ring 2, making assembly and disassembly more convenient.

[0030] like Figures 1-4As shown, in a preferred embodiment of the present invention, the upper circumferential side of the first lampshade fixing ring 1 is provided with 30-40 first deformation strip fixing grooves 11 at equal intervals, the lower circumferential side of the second lampshade fixing ring 2 is provided with 30-40 second deformation strip fixing grooves 21 at equal intervals, and the number of lampshade deformation strips 6 is 30-40, and the number of the first deformation strip fixing grooves 11, the second deformation strip fixing grooves 21 and the lampshade deformation strips 6 are matched.

[0031] like Figures 1-4 As shown, the support frame 3 includes a bulb mounting ring 31 and three "<"-shaped support frames 32. The bulb mounting ring 31 is used to mount the bulb. The upper end of the "<"-shaped support frame 32 is connected to the bulb mounting ring 31, and the middle of the "<"-shaped support frame 32 is provided with a connecting ear 321. There are three support frame positioning slots 22, which are equally spaced on the inner circumference of the second lampshade fixing ring 2. The connecting ear 321 of the "<"-shaped support frame 32 is inserted into the corresponding support frame positioning slot 22. The three "<"-shaped support frames 32 can stably support the lampshade. After the bulb is mounted, the deformable lampshade can be combined with the bulb, and it can be used as a pendant lamp, table lamp, or floor lamp.

[0032] like Figures 1-4 As shown, the support frame 3 also includes a pull rope guide ring 33. The bulb mounting ring 31 is located above the pull rope guide ring 33. The lower end of the "<"-shaped support frame 32 is connected to the pull rope guide ring 33. The other ends of the first pull rope 4 and the second pull rope 5 pass downward through the pull rope guide ring 33, and the other ends of the first pull rope 4 and the second pull rope 5 are respectively connected to pendants 41 and 51. The pull rope guide ring 33 is provided to both fix the lower end of the "<"-shaped support frame 32 and guide the first pull rope 4 and the second pull rope 5 to ensure that the two pendants are centered.

[0033] As a preferred embodiment of the present invention, the lampshade deformation strip 6 is any one of a metal lampshade deformation strip, a plastic lampshade deformation strip, or a wooden lampshade deformation strip.

[0034] The above description is merely a preferred embodiment of the present invention. Any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical solution of the present invention shall fall within the scope of the technical solution of the present invention.
