Description

Technical Field

[0001] This invention relates to the field of home furnishings, and more particularly to a children's chair, chair parts, and a method for locking and fixing the chair parts. Background Technology

[0002] Chairs are crucial to children's healthy growth and are essential tools for their learning. Most children's chairs and study chairs on the market feature adjustable seat or backrest height, and the seat or backrest is usually fixed to the main frame by a plug-in connection.

[0003] Wenxing's patent application, CN206275483U, discloses a children's growth and health chair. During operation, the backrest is secured to the frame with clips. To move the backrest up or down, the clips are released, allowing for stepless adjustment. After moving the backrest to the desired position, the clips are then secured again. The seat cushion is secured to the frame with both clips and a pin, ensuring 100% stability and child safety. To move the seat cushion up or down, the clips are released, and the knob is rotated 30 degrees, disengaging the pin from its hole. Move the seat up and down to the desired position, then pull the knob outwards 90° to return it to its original position. The pin will retract into the pin hole, securing the fixing clip. The fixing screw will lock the elastic pin, and the spring will press against the inner surface of the aluminum alloy fixing clip. The entire fixing knob is movable. When the knob is rotated 90° clockwise, it will rotate from the bottom to the top of the aluminum alloy fixing clip, and the fixing boss will lock the knob, causing the pin to exit the insertion hole. When rotated 90° counterclockwise, the knob will rotate from the top to the bottom of the aluminum alloy fixing clip, and the pin will insert into the insertion hole.

[0004] In the existing technology, since the clamping force of the fixing clip is constant and the clamping action occurs instantaneously, when adjusting the height of the chair seat or backrest, it is necessary to repeatedly open and close the fixing clip to ensure that the chair seat or backrest moves to the designated position. This causes the adjustment process to be repeated and also makes the locking structure more complicated. Summary of the Invention

[0005] To address the problems of complex locking structures and repetitive adjustment processes in existing technologies, the present invention aims to provide a locking and fixing method for a child chair, chair components, and chair components. The structure of the present invention is simpler, the operation is simpler, the adjustment process is simpler, and it can prevent the seat and backrest from wobbling up and down, ensuring the stability and reliability of the chair.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a locking and fixing method for a chair component, used to adjust the height between the seat or backrest and the main frame. The chair component includes a main frame and a sleeve. The sleeve is fitted onto the main frame. A movable first adjusting seat and a second adjusting seat are installed on the sleeve. The first adjusting seat slides with the sleeve and can extend out of the sleeve to abut against the main frame. The second adjusting seat is connected to the first adjusting seat in a way that the spacing is adjustable. The second adjusting seat and the sleeve are connected by an elastic element. The elastic element pushes the second adjusting seat to make the first adjusting seat abut against the main frame. When adjusting the height of the sleeve on the main pipe: reduce the distance between the second adjusting seat and the first adjusting seat, so that the pressure applied by the elastic element to the second adjusting seat is reduced, thereby reducing the pressure between the first adjusting seat and the main pipe. Then move the sleeve to the specified height. Then increase the distance between the second adjusting seat and the first adjusting seat, so that the pressure applied by the elastic element to the second adjusting seat is increased, thereby increasing the pressure between the first adjusting seat and the main pipe, so that the first adjusting seat and the main pipe are pressed together, and the sleeve is fixed on the main pipe.

[0007] Preferably, a connecting rod is fixed on the second adjusting seat, the connecting rod is inserted into the first adjusting seat, and the connecting rod is threadedly connected to the first adjusting seat; when adjusting the height of the sleeve on the main pipe: the length of the connecting rod inserted into the first adjusting seat can be adjusted by rotating the second adjusting seat, thereby adjusting the distance between the second adjusting seat and the first adjusting seat.

[0008] Preferably, the sleeve has an opening facing the main tube, and the elastic element, the second adjusting seat and the first adjusting seat are all disposed in the opening. One end of the second adjusting seat is connected to the first adjusting seat, and the other end of the second adjusting seat extends out of the sleeve.

[0009] Preferably, a handle is fixed to one end of the second adjusting seat that extends out of the sleeve; when adjusting the height of the sleeve on the main pipe, the first adjusting seat and the main pipe can be forcibly separated by pulling the handle outward.

[0010] Preferably, the first adjusting seat is covered with a friction block, which increases the friction between the first adjusting seat and the main pipe.

[0011] Preferably, the elastic element includes a spring, with its two ends abutting against the sleeve and the second adjusting seat, respectively.

[0012] A chair component, characterized in that it is capable of implementing the locking and fixing method of any one of claims 1-6.

[0013] A children's chair, characterized in that: it includes a chair component as described in any one of claims 7, and further includes a backrest, a seat, and legs; two positioning components are installed on the main tube, one above the other; the backrest is connected to the positioning component located on the upper side; the seat is connected to the positioning component located on the lower side; and the legs are installed at the bottom of the main tube.

[0014] Preferably, the chair back is connected to the upper sleeve in a way that allows it to swing up and down.

[0015] Preferably, the seat is connected to the sleeve located on the lower side in a manner that allows it to slide back and forth.

[0016] The beneficial effects of the technical solution of the present invention are as follows: The above method and structure adjust the pressure between the sleeve and the main pipe through the gap between the first adjusting seat and the second adjusting seat. This not only simplifies the structure for locking the sleeve and the main pipe, but also makes the pressure and friction between the main pipe and the sleeve adjustable. Furthermore, the above method can adjust the position of the sleeve on the main pipe without completely separating the sleeve and the main pipe. Thus, the position of the sleeve can be adjusted without the user having to hold the sleeve by hand, making the sleeve position adjustment process more continuous, shorter in time, and providing a better user experience.

[0025] like Figure 2-5 The chair component shown includes a main tube 1 and a positioning assembly. The positioning assembly includes a sleeve 51, a mounting base 53, a first adjusting seat 54, a second adjusting seat 55, a spring 57, and a connecting rod 56. The sleeve 51 is fitted onto the main tube 1, and the mounting base 53 is fixed to the sleeve 51. The mounting base 53 has an opening facing the main tube 1. The first adjusting seat 54, the second adjusting seat 55, the spring 57, and the connecting rod 56 are installed in the opening of the mounting base 53. The first adjusting seat 54 is located between the main tube 1 and the second adjusting seat 55. Between seats 55, the first adjusting seat 54 and the mounting seat 53 are slidably fitted. One end of the connecting rod 56 is threadedly connected to the first adjusting seat 54, and the other end of the connecting rod 56 is fixedly connected to the second adjusting seat 55. Part of the second adjusting seat 55 extends out from the mounting seat 53. The spring 57 is sleeved on the second adjusting seat 55. The two ends of the spring 57 abut against the second adjusting seat 55 and the inner wall of the opening, respectively. The spring 57 pushes the second adjusting seat 55 to make the first adjusting seat 54 extend out from the mounting seat 53 and abut against the main pipe 1.

[0026] In this preferred embodiment, the connecting rod 56 includes a threaded portion, a splined portion, and a fixed portion arranged sequentially. The threaded portion is threadedly connected to the first adjusting seat 54, and the splined portion and the fixed portion are inserted into the central hole of the second adjusting seat 55. The splined portion is splinedly connected to the second adjusting seat 55, and the second adjusting seat 55 is fixedly connected to the fixed portion by screws.

[0027] In this preferred embodiment, such as Figure 4 and Figure 5 As shown, a handle 58 is fixed on the second adjusting seat 55. To facilitate the connection of the handle 58, the connecting rod 56, and the second adjusting seat 55, the second adjusting seat is inserted into the handle 58. The end of the fixed part of the connecting rod 56 has a threaded hole. The threaded part of the screw 59 passes through the central hole of the handle 58 and is threadedly connected to the threaded hole on the connecting rod 56. When the screw 59 is tightened, the screw 59 pulls the connecting rod 56 through the thread, causing the connecting rod 56 to be locked with the second adjusting seat 55 through the spline. The screw 59 presses the handle 58 and the second adjusting seat 55 together through its head, thereby completing the connection between the second adjusting seat 55, the connecting rod 56, and the handle 58. More preferably, the handle 58 is fitted with a cap, which is located at the central hole of the handle 58 and covers the screw 59.

[0028] In this preferred embodiment, such as Figure 4 and Figure 5 As shown, a mounting sleeve 52 is installed and fixedly connected to the sleeve 51, and a mounting base 53 is fixed on the mounting sleeve 52.

The backrest 2 is connected to the positioning component located on the upper side, the seat 3 is connected to the positioning component located on the lower side, and the legs 4 are installed at the bottom of the main tube 1.

[0032] In this embodiment, for ease of description, the positioning component located on the upper side is called the chair back positioning component, and the positioning component on the lower side is called the chair seat positioning component. The difference between the chair back positioning component and the chair seat positioning component lies in the different connection methods between the first adjustment seat 54 and the main pipe 1; wherein, as shown... Figure 3 and Figure 4 As shown, the first adjusting seat 54 in the chair back positioning assembly is covered with a friction block 541. The first adjusting seat 54 abuts against the main tube 1 through the friction block 541. The friction block 541 not only increases the friction strength between the sleeve and the main tube 1, but also reduces the gap between the first adjusting seat 54 and the mounting seat 53, thereby improving the stability of the connection between the sleeve 51, the main tube 1, and the chair back 2. Figure 3 and Figure 5 As shown, in the chair seat positioning assembly, the first adjustment seat 54 has a protruding locking protrusion 542, and the main tube 1 is provided with multiple vertically oriented locking slots 11. The locking protrusion 542 on the first adjustment seat 54 is inserted into the locking slots 11 on the main tube 1. This not only improves the load-bearing capacity of the chair seat positioning assembly, but also ensures a stable connection between the chair seat 3 and the main tube 1.

A positioning seat 50 is sleeved on the connecting bracket 21, and the positioning seat 50 is fixed to the front side of the mounting cylinder 52 in the chair back positioning assembly. The positioning seat 50 has an arched positioning hole 501, and the connecting bracket 21 has a matching positioning hole 501, allowing the connecting bracket 21 to swing on the positioning seat 50.

[0034] In this preferred embodiment, such as Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the chair seat 3 is connected to the mounting cylinder 52 located on the lower side in a way that allows it to slide back and forth. Specifically, a load-bearing bracket 31 is fixed to the front side of the mounting cylinder 52 in the chair seat positioning assembly. A base plate 32 is fixed to the load-bearing bracket 31. A mounting plate 33 is slidably mounted on the base plate 32, and the mounting plate 33 is located above the base plate 32. The soft padding of the chair seat 3 is fixed to the mounting plate 33. A movable positioning rod 36 is mounted on the mounting plate 33. The base plate 32 has multiple positioning holes 501 arranged back and forth, and the positioning rod 36 is inserted into the positioning holes 501. A cover 38 is fixed to the bottom of the chair seat 3, and the cover covers the base plate and the mounting plate.

[0035] Further preferred, such as Figures 6 to 8 As shown, a U-shaped first positioning plate is fixed to the side of the mounting plate 33, with the opening of the first positioning plate facing outwards.

Figure 10 As shown, the positioning rod 36 includes a first connecting part 361, a second connecting part 362, a third connecting part 363, and a fourth connecting part 364 connected in sequence. The first connecting part 361 and the fourth connecting part 364 extend horizontally, the fourth connecting part 364 is located in front of and above the first connecting part 361, the second connecting part 362 is vertically arranged, and the third connecting part 363 is arranged front and back; as shown Figures 6 to 9 As shown, the first connecting part 361 is located below the first positioning plate 332 and the second positioning plate 333. The second connecting part 362 extends upward from bottom to top between the first positioning plate 332 and the second positioning plate 333. The fourth connecting part 364 extends from the oblong hole on the first connecting part 361 and can be inserted into the second positioning hole 322 provided on the side of the base plate 32. The second positioning plate 333 is fixed with a first positioning pin 34 and a second positioning pin 35, which are arranged vertically. The third connecting part 363 of the positioning rod 36 passes between the first positioning pin 34 and the second positioning pin 35. A torsion spring 37 is sleeved on the third connecting part 363, and the two legs of the torsion spring 37 are respectively connected to the second positioning plate 333 and the second connecting part 362. The first positioning plate 332 and the second positioning plate 333 are fixedly connected by the first positioning pin 34 and the second positioning pin 35.

[0036] Further preferred, such as Figure 6 and Figure 7 As shown, the mounting plate 33 has two sliding holes 331 arranged on the left and right sides. The sliding holes 331 extend back and forth.
