Description

Technical Field

[0001] This utility model relates to the field of dining chair technology, specifically a detachable and washable dining chair. Background Technology

[0002] A dining chair is a type of seating specifically designed for dining, typically used in restaurants, cafes, hotels, or homes. Its main function is to provide a comfortable seat, allowing users to relax and enjoy their meals.

[0003] The existing technology has the following defects or problems: Existing technology, publication number CN218515439U, discloses a dining chair, including a seat, a backrest fixedly connected to one side of the seat, a support plate below the seat, a motor on the side of the support plate near the backrest, a screw driven by the motor's output end, a threaded sleeve on the outer ring of the screw, a fixing block fixedly connected to the outer ring of the threaded sleeve near the backrest, and a fixing block fixedly connected to the middle of one side of the backrest on the side away from the threaded sleeve. Limit rods are fixedly connected to both sides of the top of the support plate, and insertion holes for matching the limit rods are opened on both sides of the bottom of the backrest. In use, this device effectively assists people in using the dining chair. The toothed plate and gear installed under the support plate move the chair forward and backward, while the motor rotates the screw, causing the threaded sleeve to move and the chair to rise and fall. This avoids the problem of existing dining chairs having a single standard size that cannot adapt to people of different ages and body shapes, improving the practicality of the dining chair, increasing user comfort, and facilitating its promotion.

[0004] The aforementioned equipment makes it difficult to install or remove the dining chairs during use, which can lead to incomplete cleaning and affect the hygiene of the chairs. Furthermore, some existing washable dining chairs lack stability, potentially causing instability when sitting or standing, thus impacting the dining experience.

[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a detachable and washable dining chair, which solves the existing problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a detachable and washable dining chair, including a seat surface, a backrest fixedly connected to the top of the seat surface, and multiple chair legs fixedly connected to the bottom of the seat surface. The bottom of the backrest is slidably connected to the outside of two rear chair legs. Sliding grooves are respectively opened on the left and right sides of the rear end of the seat surface. Sliding pins are slidably connected inside the sliding grooves. Limiting rings are fixedly connected to the outside of the sliding pins. Springs are sleeved on the outside of the sliding pins. A circular plate is fixedly connected to the left side of the sliding pins. A pull ring is provided on the left side of the circular plate. Openings are respectively opened on the adjacent sides of the multiple chair legs. Two armrests are fixedly connected to the top of the seat surface. Two connecting rods are fixedly connected to the lower ends of the two armrests. Bolts are threadedly connected to the front of the seat surface. A quick-fixing assembly is provided at the bottom of the seat surface.

[0008] As a preferred technical solution of this utility model, the quick fixing component includes a fixing frame, and the four corners of the top of the fixing frame are respectively provided with inner cavities. A limiting plate is slidably connected inside the inner cavity, and a protrusion is fixedly connected to the top of the limiting plate. A compression spring is provided inside the inner cavity.

[0009] As a preferred technical solution of this utility model, the outer sides of the two sliding pins are respectively slidably connected to the inner walls of the bottom ends of the left and right sides of the backrest, and the outer sides of the two sliding pins are respectively slidably connected to the inner walls of the top ends of the chair legs on the rear sides.

[0010] As a preferred embodiment of this utility model, the rear sides of the two armrests are respectively fixedly connected to the front ends of the left and right sides of the backrest, and the bottom ends of the plurality of connecting rods are respectively fixedly connected to the top ends of the left and right sides of the seat surface.

[0011] As a preferred technical solution of this utility model, the top ends of the two front chair legs are respectively fixedly connected to the inner wall of the bottom front end of the chair surface, and the inner walls of the two armrests are threadedly connected to the outer sides of the two bolts.

[0013] In a preferred embodiment of this utility model, the outer side of the protrusion is slidably connected to the inner wall of the inner cavity, and the bottom end of the protrusion is fixedly connected to the top end of the limiting plate.

[0014] Compared with the prior art, this utility model provides a detachable and washable dining chair, which has the following beneficial effects:

[0015] 1. A detachable and washable dining chair, comprising a sliding groove, a sliding pin, a limiting ring, a spring, a circular plate, and a pull ring. Pulling the pull ring moves the circular plate, which in turn moves the sliding pin, causing it to be pulled out from inside the backrest and legs. This allows the backrest and legs to separate from the seat. Simultaneously, the limiting ring compresses the spring, allowing the backrest to be quickly disassembled. The seat cushion, backrest, or other detachable and washable parts can then be removed, enabling thorough cleaning and disinfection of the chair and ensuring its hygiene.

[0016] 2. A detachable and washable dining chair, comprising an opening, a fixing frame, an inner cavity, a limiting plate, a protrusion, and a compression spring. The fixing frame is pressed into the chair leg through the opening. The chair leg compresses the protrusion, causing the protrusion to push the limiting plate downward. The limiting plate then compresses the inner cavity. When the fixing frame moves to the accurate position on the chair leg, the inner cavity provides a restoring force, causing the protrusion to open and close against the inner wall of the chair leg, thereby fixing the dining chair and ensuring that it will not wobble or tip over during use, and facilitating maintenance and replacement.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4In this embodiment: a detachable and washable dining chair includes a seat 1, a backrest 2 fixedly connected to the top of the seat 1, and multiple chair legs 3 fixedly connected to the bottom of the seat 1. The tops of two front chair legs 3 are respectively fixedly connected to the inner wall of the bottom front side of the seat 1. The bottom of the backrest 2 is slidably connected to the outside of two rear chair legs 3. Sliding grooves 4 are respectively opened on the left and right sides of the rear end of the seat 1. Sliding pins 5 are slidably connected inside the sliding grooves 4. The outsides of two sliding pins 5 are respectively slidably connected to the inner walls of the tops of the rear chair legs 3 on both sides, and to the inner walls of the bottom left and right sides of the backrest 2. Limiting rings 6 are fixedly connected to the outside of the sliding pins 5. A spring 7 is fitted around the movable pin 5. A circular plate 8 is fixedly connected to the left side of the sliding pin 5. A pull ring 9 is provided on the left side of the circular plate 8. Openings 10 are respectively provided on the adjacent sides of multiple chair legs 3. Two armrests 11 are fixedly connected to the top of the seat 1. The inner walls of the two armrests 11 are threadedly connected to the outer sides of two bolts 13. The rear sides of the two armrests 11 are respectively fixedly connected to the left and right front ends of the backrest 2. Two connecting rods 12 are respectively fixedly connected to the lower ends of the two armrests 11. The bottom ends of multiple connecting rods 12 are respectively fixedly connected to the top of the left and right sides of the seat 1. The front side of the seat 1 is threadedly connected to two bolts 13. A quick-fixing assembly is provided at the bottom of the seat 1.

[0024] In this embodiment, when the pull ring 9 is pulled to move the sliding pin 5 to the left, the sliding pin 5 will disengage from the inner wall of the top of the rear chair leg 3 and the inner walls of the bottom of the left and right sides of the backrest 2. At this time, the backrest 2 is no longer limited by the sliding pin 5 and can be slid upward along the rear chair leg 3 to be removed, thereby realizing the separation of the backrest 2 from the seat 1 and the chair leg 3, which facilitates the disassembly and cleaning of the seat 1 and the backrest 2. The bolt 13 realizes the stable connection between the armrest 11 and the seat 1. The armrest 11, the seat 1, and the backrest 2 form a stable overall frame structure, which enhances the overall stability and comfort of the seat.

[0025] Example 2

[0026] like Figure 1 - Figure 4 As shown, the quick-fixing assembly includes a fixing frame 14, the outside of which is slidably connected to the inner wall of the opening 10. The top four corners of the fixing frame 14 are respectively provided with inner cavities 15. The inner cavity 15 is slidably connected to a limiting plate 16. The top of the limiting plate 16 is fixedly connected to a protrusion 17. The outside of the protrusion 17 is slidably connected to the inner wall of the inner cavity 15. The bottom of the protrusion 17 is fixedly connected to the top of the limiting plate 16. The outside of the protrusion 17 is in contact with the inner wall of the opening 10. A compression spring 18 is provided inside the inner cavity 15.

[0027] In this embodiment, when the fixing frame 14 is installed in the appropriate position, the spring 18 applies an upward thrust to the limiting plate 16 under the elastic force of the spring 18. Since the top of the limiting plate 16 is fixedly connected to the protrusion 17, this thrust will cause the protrusion 17 to press tightly against the inner wall of the opening 10. Through the friction between the protrusion 17 and the inner wall of the opening 10 and the radial limiting effect of the protrusion 17 on the opening 10, the fixing frame 14 is relatively fixed in the opening 10, thereby ensuring the stability of the connection between the fixing frame 14 and the chair leg 3; when it is necessary to disassemble the fixing frame 14, it is necessary to overcome the elastic force of the spring 18. This can be done by pressing the protrusion 17 into the inner cavity 15, causing the protrusion 17 to drive the limiting plate 16 to slide downward against the elastic force of the spring 18. When the protrusion 17 is fully retracted into the inner cavity 15, so that it no longer contacts the inner wall of the opening 10 or no longer effectively limits the opening 10, the fixing bracket 14 can slide freely on the inner wall of the opening 10, and can then be pulled out from the opening 10 to complete the disassembly operation of the fixing bracket 14 and the chair leg 3.

[0028] The working principle and usage of this utility model are as follows: When the pull ring 9 is pulled to move the sliding pin 5 to the left, the sliding pin 5 will disengage from the inner wall of the top of the rear chair leg 3 and the inner walls of the bottom of the left and right sides of the backrest 2. At this time, the backrest 2 is no longer limited by the sliding pin 5 and can be slid upward along the rear chair leg 3 to be removed, thereby realizing the separation of the backrest 2 from the seat 1 and the chair leg 3, which facilitates the disassembly and cleaning of the seat 1 and the backrest 2. The bolt 13 realizes the stable connection between the armrest 11 and the seat 1. The armrest 11, the seat 1, and the backrest 2 form a stable overall frame structure, which enhances the overall stability and comfort of the seat. When the fixing bracket 14 is installed in the appropriate position, under the elastic force of the compression spring 18, the compression spring 18 will apply an upward pushing force to the limiting plate 16. Since the top of the limiting plate 16 is fixedly connected to the protrusion 17, this pushing force will make the protrusion 17 press tightly against the inner wall of the opening 10. The friction between the protrusion 17 and the inner wall of the opening 10, as well as the radial limiting effect of the protrusion 17 on the opening 10, achieves relative fixation of the fixing frame 14 within the opening 10, thus ensuring the stability of the connection between the fixing frame 14 and the chair leg 3. When it is necessary to disassemble the fixing frame 14, the elastic force of the compression spring 18 needs to be overcome. This can be achieved by pressing the protrusion 17 into the inner cavity 15, causing the protrusion 17 to drive the limiting plate 16 to slide downwards against the elastic force of the compression spring 18. When the protrusion 17 is fully retracted into the inner cavity 15, so that it no longer contacts the inner wall of the opening 10 or no longer effectively limits the opening 10, the fixing frame 14 can slide freely on the inner wall of the opening 10, and can then be pulled out of the opening 10, completing the disassembly operation of the fixing frame 14 and the chair leg 3.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
