Description

Technical Field

[0001] This invention relates to the field of display cabinet support device technology, and more specifically, to an integrated shelf device for display cabinets. Background Technology

[0002] In the field of display case support systems, traditional display case shelves are usually modular, placed inside the display case, and then fixed layer by layer according to the requirements of the goods to be displayed. When loading goods, the goods can only be put in from one side of the display case door, which is not only inefficient, but also prone to causing the goods piled up in front of the door to slip off and become unevenly stacked.

[0003] Secondly, the modular structure of traditional display cabinet shelves makes adjusting shelf height and position cumbersome, requiring disassembly and reinstallation of the shelves.

[0004] Furthermore, traditional display case shelves limit the placement and display effect of goods. There is a need for a new display case support device that can solve the problems of traditional display case shelves, improve the efficiency of retrieving and placing goods, and provide more flexible adjustment of shelf positions and enhanced product display. This method does have certain inefficiencies when placing goods.

[0005] Therefore, there is a need to provide a display case support device that facilitates the retrieval and placement of goods.

[0006] In view of this, we propose an integrated shelving device for display cases.

A fixing protrusion is integrally formed at the outer corner position of the top surface of the bottom corner bracket. A rotating shaft is integrally formed on the inner protrusion of the top surface of the bottom corner bracket. The rotating shaft is rotatably connected to the inside of two circular protrusions at the bottom position of the inner side wall of the supporting vertical beam through a bearing.

[0022] In the technical solution of the present invention, the same locking pin is slidably inserted into the interior of both fixed protrusions. The external dimensions of the locking pin are adapted to the internal dimensions of the through hole of the fixed protrusion. The end of the locking pin is rotatably connected to a pin body bend via a bearing. A shock-absorbing pad is adhered and fixed to the inner side wall of the bottom corner bracket near the bottom.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. The display case uses an integrated shelving device. When the movable support mechanism needs to be pulled out of the display case, by installing a bottom folding mechanism at the bottom of the four support beams and aligning the position of the bottom corner bracket, the bottom level of the bottom casters of the bottom corner bracket can be kept consistent with the bottom level of the pulley, allowing the movable support mechanism to be easily pulled out of the cabinet shell.

[0028] 2. The display case uses an integrated shelving device. When the movable support mechanism needs to be reinstalled inside the display case, the guide groove inside the outer shell of the cabinet, together with the sloping groove on the bottom surface of the guide groove front wall, facilitates the guide wheels to easily enter the interior of the guide groove. At the same time, when the guide wheels slide to the predetermined position, the fixing groove set on the bottom surface of the guide groove wall can prevent the movable support mechanism from moving arbitrarily.

[0029] 3. This display case uses an integrated shelf device. By moving the lever in the moving component, the relative position of the movable buckle in the fixed component is changed. This, along with the traction rope, changes the position of the limit slider above the moving slider, bringing the bent end of the stop rod closer to the limit block. At this point, inserting a pin into the insertion hole and the through hole of the buckle body ensures that the adjustable bracket is fixed on the support beam. Removing the pin allows the fixing component to return to its original position under the elastic force of the first and second pressure springs, thus allowing the height of the adjustable bracket to be freely adjusted. At the same time, moving the movable block inward ensures that the overall structure of the display rack is fixed in the position of the four sets of adjustable brackets. Attached Figure Description

[0062] Furthermore, the fixed frame 21 is welded and fixed to the supporting vertical beam 20, and the supporting horizontal beam 22 is fixedly connected to the outer wall of the supporting vertical beam 20 by bolts. The length of the supporting horizontal beam 22 is adapted to the length of the guide groove 101. The beam support 23 is fixedly connected to the bottom surface of the supporting horizontal beam 22 by screws. The guide wheel 24 is rotatably connected to the inside of the beam support 23. A rubber handrail 25 for easy movement of the entire movable support mechanism 2 is glued and fixed to the outer wall of the fixed frame 21 at the front top position.

[0063] Furthermore, the supporting vertical beam 20 is used to ensure the overall strength of the mobile support mechanism 2, the beam slide 201 is used to facilitate the movement of the overall structure of the adjustable bracket 4, the limiting block 202 is used to limit the position of the adjustable bracket 4 on the supporting vertical beam 20, the fixed frame 21 is used to provide a fixed base point for the rubber handrail 25, and at the same time, it works with the supporting horizontal beam 22 to fix the four supporting vertical beams 20 into a whole. The supporting horizontal beam 22 is used to provide a fixed base point for the beam bracket 23, the beam bracket 23 is used to provide a rotation base point for the guide wheel 24, and the rubber handrail 25 is used to facilitate the operator to pull the mobile support mechanism 2.

[0064] In this embodiment, as Figures 10-12 As shown, the bottom of each of the four supporting vertical beams 20 is provided with a bottom folding mechanism 3. The bottom folding mechanism 3 includes a bottom corner bracket 30 that is rotatably connected to the supporting vertical beam 20, a tension spring 36 that is connected between the inner side wall of the bottom corner bracket 30 and the bottom surface of the fixed frame 21, and a bottom caster 38 that is provided at the bottom of the bottom corner bracket 30.

[0065] Furthermore, a frame slot 301 with an arc-shaped longitudinal cross-section is provided on the inner side wall of the bottom corner bracket 30 near the center position. A fixing protrusion 31 is integrally formed on the outer corner of the top surface of the bottom corner bracket 30. A rotating shaft 32 is integrally formed on the inner protrusion of the top surface of the bottom corner bracket 30. The rotating shaft 32 is rotatably connected to the inside of two circular protrusions at the bottom of the inner side wall of the supporting vertical beam 20 through a bearing.

[0066] Furthermore, the same locking pin 33 is slidably inserted into the interior of both fixing protrusions 31. The external dimensions of the locking pin 33 are adapted to the internal dimensions of the through hole of the fixing protrusion 31. The end of the locking pin 33 is rotatably connected to the pin body bend 34 via a bearing. The shock-absorbing pad 35 is adhered and fixed to the inner side wall of the bottom corner bracket 30 near the bottom. The two ends of the tension spring 36 are respectively locked and fixed to the center of the inner groove wall of the frame slot 301 and the bottom surface of the fixing frame 21 via integrally formed hooks. The bottom surface of the bottom corner bracket 30 is fixedly connected to the wheel bracket 37 by screws. The bottom caster 38 is rotatably connected to the inside of the wheel bracket 37.

[0067] Furthermore, the bottom corner bracket 30 is used to ensure the overall structural strength of the bottom folding mechanism 3, the frame slot 301 is used to provide a fixed base point for the pin bend 34 and storage space after shrinking, and the rotating shaft 32 is used to allow the bottom corner bracket 30 to change its relative position with the supporting vertical beam 20. After manually rotating the two bottom corner brackets 30 to a state perpendicular to the bottom surface, the pin 33 is inserted into the through hole of the fixing protrusion 31 and the through hole of the supporting vertical beam 20. After it is fully inserted, the pin bend 34 is rotated to ensure the bottom corner bracket is securely attached. When the bottom corner bracket 30 is retracted, after the locking pin 33 is pulled out, the bottom corner bracket 30 changes its relative position with the support beam 20 under the elastic force of the tension spring 36. The shock-absorbing pad 35 is used to alleviate the impact force generated between it and the fixed frame 21. The wheel bracket 37 is used to provide a rotation base point for the caster 38. The caster 38 is used to keep the movable support mechanism 2 at the same horizontal height as the pulley 13 after it is pulled outward, so as to ensure the overall stability of the movable support mechanism 2.

[0068] In this embodiment, as Figures 13-17 As shown, several sets of horizontally arranged and linearly distributed adjustable brackets 4 are provided on the inner sidewalls of the four supporting vertical beams 20. The adjustable brackets 4 include a movable component 40 slidably connected to the inner sidewall of the supporting vertical beam 20, a fixed component 41 disposed on the top of the movable component 40, and a pin 42 disposed inside the movable component 40 and the fixed component 41.

[0069] Furthermore, the moving component 40 includes a moving slider 401, a block support 402 integrally formed on the front side wall of the moving slider 401 with a longitudinal cross section of right angle triangle, a lever 403 rotatably connected at both ends of the top of the two block supports 402 near the top position, and two limiting protrusions 404 integrally formed on the outer side wall of the moving slider 401 near the top position.

[0070] Furthermore, the inner wall of the movable slider 401 is provided with a block slot 4010 that matches the size of the supporting vertical beam 20. At the four corners of the top surface of the movable slider 401, there are storage holes 4011 for providing a place for the first pressure spring 411. The inner wall of the block slot 4010 of the movable slider 401 is provided with a slanted groove 4012 with a longitudinal cross section of an inverted right triangle. On the extension plate of the front side wall of the movable slider 401, there are two limiting grooves 4013 with a longitudinal cross section of an inverted T shape. The block support 402 is provided with a through hole 4020 that matches the size of the pin 42 at the middle position inside.

[0071] The movable slider 401 is used to ensure the overall structural strength of the movable component 40. The block slot 4010 is used to facilitate the movement of the movable slider 401 on the supporting vertical beam 20. The inclined groove 4012 is used to change the relative position of the stop rod 414 when it moves downward. The limiting groove 4013 is used to limit the range of movement of the movable latch 416. The block bracket 402 is used to provide rotation space for the movable buckle 417. The insertion hole 4020 is used to cooperate with the buckle through hole 4170 to insert the pin 42 and ensure the fixed position of the movable buckle 417. The lever 403 is used to facilitate changing the position of the movable buckle 417. The limiting protrusion 404 is used to cooperate with the limiting bracket 413 to limit the maximum upward movement distance of the fixed component 41.

[0072] In this embodiment, as Figures 13-17 As shown, the fixing component 41 includes a limiting slider 410, a first pressure spring 411 disposed at the four corners of the bottom surface of the limiting slider 410, two snap-fit ​​sliders 412 disposed on the top surface of the limiting slider 410, two limiting brackets 413 disposed at the front and rear ends of the bottom surface of the limiting slider 410, a blocking rod 414 rotatably connected to the inner side wall of the limiting slider 410, two traction ropes 415 disposed on the bottom surface of the blocking rods 414, a movable locking block 416 disposed near the end of the two traction ropes 415, a movable buckle 417 disposed at the end of the two traction ropes 415, and a second pressure spring 418 disposed at the end of the top surface of the movable buckle 417.

[0073] Furthermore, the two ends of the first pressure spring 411 are welded and fixed to the bottom surface of the limiting slider 410 and the bottom hole wall of the receiving hole 4011, respectively. The snap-fit ​​slider 412 and the limiting bracket 413 are integrally formed with the limiting slider 410. The longitudinal section of the blocking rod 414 is L-shaped. The two ends of the traction rope 415 are heat-fused to the bottom surface of the blocking rod 414 and the top surface of the movable buckle 417. The movable block 416 is slidably connected to the inside of the limiting slide groove 4013. The movable buckle 417 has a buckle body through hole 4170 that matches the size of the insertion hole 4020. The upper and lower ends of the second pressure spring 418 are welded and fixed to the top surface of the movable buckle 417 and the bottom surface of the front extension plate of the movable slider 401, respectively.

[0074] Furthermore, the limiting slider 410 is used to ensure the stability of the overall structure of the fixing assembly 41, the first pressure spring 411 is used to provide an upward force to the limiting slider 410 through its own elasticity, and the locking slider 412 is used to ensure that the limiting slider 410 can be slidably connected to the inner wall of the supporting vertical beam 20. Moving the lever 403 causes the position of the movable buckle 417 to change, so that the movable buckle 417 pulls the traction rope 415, causing the blocking rod 414 to move downwards along with the limiting slider 410. After moving downwards, the blocking rod 414 contacts the groove wall of the inclined groove 4012, and its own position changes. The rotation causes the bottom bending plate to contact the top of the limiting block 202, thereby changing the position of the movable buckle 417 and keeping the adjustable bracket 4 fixed on the inner side wall of the supporting vertical beam 20. As the traction rope 415 moves, it drives the movable block 416 to move in the limiting slide groove 4013 toward the square of the placement frame 5, so that the placement rod 52 enters the groove on the outer side wall of the movable block 416, thereby ensuring the fixation of the overall structure of the placement frame 5. The second pressure spring 418 is used to make the movable buckle 417 return to its original position without external force through its own elasticity.

[0075] In this invention, the same set of placement racks 5 are provided between the adjustable brackets 4 on the same horizontal line;

[0076] Furthermore, the placement rack 5 includes a square frame 50, a lifting strip frame 51 welded and fixed to the top front surface of the square frame 50, several placement rods 52 linearly distributed and welded and fixed to the inner side of the frame wall of the square frame 50, and a reinforcing rod 53 welded and fixed to the top rear end position of the several placement rods 52. The longitudinal section of the lifting strip frame 51 is inverted U-shape, and the longitudinal section of the placement rods 52 is inverted L-shape.

[0077] The square frame 50 is used to ensure the strength of the overall structure. The lifting frame 51 is used to facilitate the placement and retrieval of the square frame 50 by the operator. The placement rod 52 is used to place the goods and provide a placement platform. The reinforcing rod 53 is used to connect several placement rods 52 into a whole to ensure the strength of the placement rack 5.

[0078] Furthermore, it should be noted that due to the advanced nature of this technical solution, this invention has broad application prospects in the field of display case support devices. By making the display case into a single unit and installing rotatable wheels on the base plate, the display case can be easily pulled out of the cabinet for the placement and organization of goods. This design can greatly improve operational efficiency and save time and labor costs.

[0079] The technological application prospects of this invention are mainly reflected in the following aspects:

[0080] 1. Retail Industry: Display cases are common display tools in retail stores. With the display case support device of this invention, goods can be conveniently placed and organized, improving the effect and attractiveness of the goods display, thereby increasing sales and profits.

The display case support device of this invention can provide a convenient display and arrangement method, protect the safety of the displayed items, and improve the exhibition effect.

[0083] In summary, the present invention has a very wide range of applications and is suitable for various places that need to display and exhibit goods or items, such as retail stores, shopping malls, and exhibitions. As people's requirements for display effects and display methods continue to increase, the market demand for the present invention will also continue to grow.

[0084] When using the integrated shelf device for the display cabinet of the present invention, firstly, the display cabinet 1 is moved to the designated position by the pulley 13, and then the entire movable support mechanism 2 is pulled outward by the rubber handle 25 on the top front fixed frame 21 of the movable support mechanism 2.

[0085] Subsequently, after the two support beams 20 axially distributed at the front end of the movable support mechanism 2, together with the bottom folding mechanism 3 at the bottom, are pulled out to the outside of the cabinet shell 10, the bottom corner brackets 30 in the two sets of bottom folding mechanisms 3 are manually moved to a state perpendicular to the bottom surface, and the locking pin 33 is inserted between the two fixing protrusions 31. Then, the pin body bend 34 is rotated to ensure that the position of the locking pin 33 is fixed after insertion.

[0086] Continue to pull the entire movable support mechanism 2 outward by pulling the rubber handle 25. After the two support beams 20 axially distributed at the rear end of the movable support mechanism 2, together with the bottom folding mechanism 3 at the bottom, are pulled out to the outside of the cabinet shell 10, repeat the operation of the bottom folding mechanism 3 to easily pull the movable support mechanism 2 to the outside of the cabinet shell 10.

[0087] Subsequently, the lever 403 is moved to change the position of the movable buckle 417, so that the movable buckle 417 pulls the traction rope 415, which in turn moves the stop rod 414 and the limit slider 410 downward together. After the stop rod 414 moves downward, it contacts the groove wall of the inclined groove 4012 and rotates its own position, so that the bottom bending plate can contact the top of the limit block 202, thus ensuring that the adjustable bracket 4 is fixed on the support beam 20.

[0088] As the traction rope 415 moves, it drives the moving block 416 to move towards the square shape of the placement frame 5 within the limiting slide groove 4013, so that the placement rod 52 enters the groove on the outer wall of the moving block 416, thereby ensuring the fixation of the overall structure of the placement frame 5.

[0089] The height between multiple sets of placement racks 5 can be adjusted by pulling out the pin 42 inserted into the socket 4020 and the buckle through hole 4170.
