Description

Technical Field

[0001] This application relates to the field of seating technology, and more specifically, to a special seat for live streaming. Background Technology

[0002] With the rapid development of the online live streaming industry, the demand for comfortable and adjustable chairs among live streamers is increasing. As a core piece of equipment for long-term work, live streaming chairs are usually equipped with headrests on the backrest to provide support for the user's head and neck.

[0003] Currently, in the process of adjusting the headrest of a chair, the headrest can only provide support for the user's head and neck in a fixed position, which is difficult to meet the user's comfort needs. Some chairs have headrests that can be adjusted up and down and angled to adapt to different sitting postures in the height direction as much as possible. However, during the adjustment process, the user needs to get up to adjust the position of the headrest structure. During the adjustment, the user's head and neck lose contact with the headrest, so they cannot intuitively feel the impact of the headrest position change. This requires the user to get up and operate repeatedly, increasing the user's frustration.

[0004] Therefore, a special chair for live streaming is needed to solve the above problems. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide a special chair for live streaming, comprising: a chair, a support frame fixedly connected to the upper end of the chair by two fixed rods, a guide rail mounted on the support frame, a sliding frame capable of vertical movement mounted on the guide rail, a support seat capable of vertical swinging mounted at the front end of the sliding frame, a baffle capable of vertical sliding on the support frame, two symmetrical slots at the rear end of the support frame, guide strips corresponding to the front and rear of the two slots fixedly mounted at the front end of the baffle, the guide strips and the slots being interference-fitted, four corner holes distributed on the end face of the support frame, threaded parts inserted into the holes, the threaded parts being threadedly fixedly connected to the guide rail, the width of the baffle being greater than the distance between the two left and right holes, the front end of the support seat abutting against the user's head area, curved stops fixed at the left and right ends of the support seat, four curved stops symmetrically arranged vertically, and headrests fixed at adjacent curved stops.

[0007] Preferably, two guide rails are provided symmetrically on the left and right sides. The guide rails extend vertically and fit against the front end face of the support frame. Sliding grooves are provided at the far ends of the two guide rails. Insertion holes are evenly distributed vertically on the rear sidewalls of the sliding grooves on both sides. Two vertically symmetrical insertion sleeves are fixed on the rear end faces of the two guide rails. Threaded grooves are provided on the insertion sleeves, which are connected to the guide rails and the insertion sleeves from front to back. The four threaded grooves and the four corresponding threaded parts are on the same axis. The insertion sleeves are inserted into the sidewalls of the insertion holes, and the threaded grooves are connected to the threaded parts.

[0008] Preferably, the rear end of the sliding frame has an opening that can fit against the front ends of the two guide slides, and both ends of the sliding frame are fixed with protrusions that fit against the far ends of the two guide slides. The near ends of the two protrusions are fixed with insertion blocks, which are slidably connected to the sidewall of the sliding groove. Two left-right distributed support blocks are fixed on the front sidewall of the opening of the sliding frame. The support blocks can fit against and support the front end of the support frame. The front end of the sliding frame is fixed with two left-right symmetrical connecting seats. The support seats are rotatably connected between the two connecting seats. Each of the two protrusions has an insertion rod that can slide back and forth. The far ends of the two insertion rods are fixed with sliding rods. Rotary disks are rotatably connected to the left and right ends of the sliding frame. Arc-shaped sliding grooves are opened in the rotating disks. The arc-shaped sliding grooves are arranged in an arc shape, and the inner end of the arc-shaped sliding grooves is located near the center of the rotating disk. Straight sliding grooves are opened on the sliding frame.

[0009] Preferably, there is an overlapping area between the arc-shaped sliding groove and the straight sliding groove. Rotating rods are fixedly mounted on the mutually distant ends of the two rotating disks. Sleeves are fixedly connected to the rotating rods. A torsion spring is provided on the outer periphery of the rotating rod. The torsion spring includes a torsion spring fixedly connected to the sleeve and a convex ring fixedly connected to the torsion spring. The convex ring is disposed on the outer periphery of the rotating rod and fixedly connected to the end face of the sliding frame. A rotating wheel is fixedly mounted on the outer periphery of the sleeve. Uniformly distributed grooves are formed on the outer periphery of the rotating wheel. A contraction cavity is formed inside the insertion block. The insertion rod slides back and forth with the side wall of the contraction cavity. The insertion rod can be inserted into the uniformly distributed insertion holes.

[0010] Preferably, the front end portion of the connecting seat, and the left end face of the connecting seat located on the left side, is provided with a push block that can move left and right. The push block includes a sliding plate located at the outer end of the connecting seat and a rod inserted into the connecting seat. The outer periphery of the sliding plate is provided with circumferentially evenly distributed protrusions. An arc-shaped sliding cavity is formed inside the connecting seat. The arc-shaped sliding cavity is located at the rotational connection between the connecting seat and the support seat. A push plate that can slide left and right and has the same size as the side wall of the arc-shaped sliding cavity is provided inside the arc-shaped sliding cavity. The rod is fixedly connected to the push plate. A spring (such as...) is connected between the push plate and the side wall of the arc-shaped sliding cavity. Figure 9 As shown, the spring is fixedly connected to the side wall of the arc-shaped cavity at the left end of the push plate. The right side wall of the arc-shaped cavity is provided with a uniformly distributed insertion groove along the arc direction of the arc-shaped cavity. The rear end of the support base is connected to a spring plug that can be set inside and outside and is set on the left end of the support base. The spring plug can be inserted into the insertion groove. The spring plug is inserted into the end of the connecting base in a hemispherical shape. The radius of the round head of the spring plug is larger than the opening depth of the insertion groove. The push plate can abut against the spring plug.

[0011] Preferably, the support base includes a support frame located at the front end and fitting against the headrest, and a rotating plate located at the rear end and rotatably connected to the connecting seat. A connecting rod is connected between the rotating plate and the connecting seat, and the connecting rod is fixedly connected to the support base and rotatably connected to the two connecting seats.

[0012] The beneficial effects of this application are as follows:

[0013] 1. Through the cooperation of the guide rail, sliding frame and support seat, the support seat can be adjusted in height and angle on the basis of the seat. This allows users to selectively adjust the position and angle of the headrest supporting the head and neck according to their own needs. Moreover, the user does not need to lift their head off the support seat during the adjustment process. This allows users to more intuitively feel the changes in the support seat's impact on the support through their head position, eliminating the annoyance of repeatedly getting up to adjust the position of the support seat.

[0014] 2. The plug rod is inserted into the plug hole, so that the cylindrical part of the plug rod contacts the side wall of the plug hole. This reduces the possibility of the plug rod slipping and dislodging from the plug hole during use. Similarly, the spring plug and the plug groove are engaged to further improve the stability of the support base, so that the support base can provide stable support for the user's head and neck.

[0015] 3. The concave and convex design of the rotating wheel and the push block allows users to intuitively feel the adjustment position without having to visually observe the position of the rotating wheel and the push block, making it convenient, quick, and easy to use.

[0038] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] Referring to Figures 1-4, a special chair for live streaming includes: a seat 10, with a support frame 20 fixedly connected to the upper end of the seat 10 via two fixed rods; a guide slide 30 mounted on the support frame 20; a sliding frame 40 capable of vertical movement mounted on the guide slide 30; a support seat 60 capable of vertical swinging mounted at the front end of the sliding frame 40; a baffle 21 capable of vertical sliding on the support frame 20; two symmetrical slots 22 at the rear end of the support frame 20; guide strips corresponding to the front and rear of the two slots 22 fixedly mounted at the front end of the baffle 21; the guide strips and slots 22 are interference-fitted; four corner holes 23 are provided on the end face of the support frame 20; threaded parts 24 are inserted into the holes 23; the threaded parts 24 can be partially threadedly fixed to the guide slide 30; the width of the baffle 21 is greater than the distance between the two holes 23; the front end of the support seat 60 abuts against the user's head area; the support seat 60... The left and right ends are fixed with curved stops, and there are four curved stops symmetrically arranged vertically. Headrests are fixed at the adjacent curved stops. The support frame 20 is fixedly installed on the top of the seat 10 by a fixing rod. The head position of the user when sitting on the seat 10 is set at the support frame 20. According to the user's height, the vertical height of the support seat 60 can be adjusted at the guide rail 30. Similarly, the vertical tilt angle of the support seat 60 can be adjusted at the sliding rail 40.

[0040] Referring to Figure 2-5, two guide rails 30 are symmetrically arranged on the left and right sides, and the guide rails 30 extend vertically and fit snugly against the support frame.

[0041] On the front end face of the support frame 20, sliding grooves 31 are provided at the far ends of the two guide slides 30. The rear sidewalls of the sliding grooves 31 on both sides are connected by evenly distributed insertion holes 32. Two symmetrically arranged insertion sleeves 33 are fixed to the rear end face of each guide slide 30. Threaded grooves 34 are provided on the insertion sleeves 33, connecting the guide slide 30 and the insertion sleeves 33. The four threaded grooves 34 and the corresponding four threaded parts 24 are on the same axis. The insertion sleeves 33 are inserted into the sidewalls of the insertion holes 23. Threaded grooves 34 are connected to the threaded parts 24, and the threaded parts 24 are threadedly connected to the threaded grooves 34. Before assembly, by removing the two guide slides 30, the protruding ends of the guide slides 30 with the insertion sleeves 33 are inserted from the front end of the support frame 20 backwards. The two insertion sleeves 33 on one guide slide 30 are inserted into the upper and lower insertion holes 23. The user then temporarily supports the support frame 20 by removing the threaded part 24 and inserting it into the socket 23 (plug sleeve 33) from the rear end of the support frame 20. This allows the threaded part 24 to connect with the inner threaded groove of the plug sleeve 33, thus fixing the left and right guide slides 30 in place. After that, the user removes the baffle 21 and inserts it from the rear end of the support frame 20 in a vertical direction, so that the baffle 21 and the side wall of the slot 22 are interference-fitted to block the socket 23.

[0042] Reference Figure 6-11The sliding frame 40 has an opening at its rear end that can fit against the front ends of the two guide frames 30. Both ends of the sliding frame 40 have protrusions that fit against the far ends of the two guide frames 30. The near ends of the two protrusions each have a connecting block 41 that slides against the sidewall of the sliding groove 31. Two left-right distributed support blocks 42 are fixed on the front sidewall of the opening of the sliding frame 40. These support blocks 42 fit against the front end of the support frame 20. The front end of the sliding frame 40 has two symmetrical connecting seats 43. A support seat 60 is rotatably connected between the two connecting seats 43. Each of the two protrusions has a sliding rod 45 that can slide back and forth. The far ends of the two connecting rods 45 each have a sliding rod 46. Rotary disks 47 are rotatably connected to both ends of the sliding frame 40. Arc-shaped sliding grooves 48 are formed within the rotating disks 47. The arc-shaped sliding grooves 48 are arc-shaped and... The inner end of the sliding frame 40 is located near the center of the rotating disk 47. A straight sliding groove 49 is provided on the sliding frame 40. There is an overlapping area between the arc sliding groove 48 and the straight sliding groove 49 (the arc sliding groove 48 and the straight sliding groove 49 are away from the center of the rotating disk 47). Rotating rods are fixedly provided at the far ends of the two rotating disks 47. A sleeve 51 is fixedly connected to the rotating rod. A torsion spring 50 is sleeved on the outer periphery of the rotating rod. The torsion spring 50 includes a torsion spring fixedly connected to the sleeve 51 and a convex ring fixedly connected to the torsion spring. The convex ring is located on the outer periphery of the rotating rod and is fixedly connected to the end face of the sliding frame 40. The two ends of the torsion spring 50 are fixedly connected to the sliding frame 40 and the sleeve 51, respectively. A rotating wheel 52 is fixedly provided on the outer periphery of the sleeve 51. A uniformly distributed groove is provided on the outer periphery of the rotating wheel 52. A contraction cavity 53 is provided in the insertion block 41. The insertion rod 45 slides back and forth with the side wall of the contraction cavity 53. It can be inserted and mated with the evenly distributed insertion holes 32;

[0043] Two plug-in blocks 41 on the sliding frame 40 are inserted into the side wall of the sliding groove 31. The plug-in blocks 41 can slide up and down in the sliding groove 31. The plug-in rods 45 extending from the plug-in blocks 41 are inserted into the plug-in holes 32 to limit and fix the sliding frame 40. During the use of the sliding frame 40, the two connecting seats 43 at the rear end abut against the end face of the support frame 20 to distribute the force transmitted from the support seat 60. When adjusting the height, the user sits on the seat 10 with their head partially in contact with the support seat 60, thus more intuitively feeling the support change brought about by the height adjustment of the sliding frame 40. Specifically, the user rotates the rotating wheels 52 at both ends, causing the rotating wheels 52 to drive the fixedly connected sleeve 51 to rotate. The sleeve 51, in conjunction with the rotation of the rotating rod of the rotating disk 47, drives the connected torsion spring 50 to move. The torsion spring 50 overcomes its own elasticity and twists, and the rotating disk 47 follows the fixedly connected sleeve 51. The synchronous rotation causes the position of the arc groove 48 on the rotating disk 47 to change. The arc at the arc groove 48 gradually moves closer to the center of the rotating disk 47. Under the abutting cooperation of the sliding rod 46 with the arc groove 48 and the straight groove 49, the insertion rod 45 is driven to retract into the shrinkage cavity 53, thereby causing the insertion rod 45 to lose its insertion cooperation with the side wall of the insertion hole 32. This allows the sliding frame 40 to move freely on the guide frame 30 for height adjustment. By inserting a push spring into the shrinkage cavity 53 to abut against the insertion rod 45, the reset effect of the insertion rod 45 is improved, preventing jamming.

[0044] The front end of the connecting seat 43, and on the left end face of the left end of the connecting seat 43, is provided with a push block 54 that can move left and right. The connecting seat 43 is provided with a push block 54 for adjusting the angle. The push block 54 includes a sliding plate located at the outer end of the connecting seat 43 and a rod inserted into the connecting seat 43. The outer periphery of the sliding plate is provided with circumferentially evenly distributed protrusions. An arc-shaped sliding cavity 57 is opened in the connecting seat 43. The arc-shaped sliding cavity 57 is located at the rotational connection between the connecting seat 43 and the support seat 60. The arc-shaped sliding cavity 57 is provided with a push plate 55 that can slide left and right and has the same size as the side wall of the arc-shaped sliding cavity 57. The rod is fixedly connected to the push plate 55. A spring 56 is connected between the push plate 55 and the side wall of the arc-shaped sliding cavity 57. Figure 9As shown, spring 56 is fixedly connected to the side wall of the arc-shaped cavity 57 at the left end of push plate 55. Insertion slots 58 are uniformly distributed along the arc direction of arc-shaped cavity 57 on the right side wall of arc-shaped cavity 57. The rear end of support base 60 is connected to spring plug 59 which can be set inside and outside and is set on the left end of support base 60. Spring plug 59 can be inserted into insertion slot 58. Spring plug 59 is hemispherical when inserted into connecting base 43. The radius of the round head of spring plug 59 is larger than the opening depth of insertion slot 58. Push plate 55 can abut against spring plug 59.

[0045] Similarly, by pushing the push block 54 into the connecting seat 43, the push block 54 causes the push plate 55 to move inward against the spring force of the spring 56. The end face of the push plate 55 can fit against the side wall of the arc-shaped cavity 57 and the round head of the spring insert 59. Under the abutment of the push plate 55, the cylindrical end of the spring insert 59 is pulled out from the insertion groove 58 and retracted into the support seat 60. The round head of the spring insert 59 fits against the side wall of the insertion groove 58, thereby reducing the resistance to changing the vertical angle of the support seat 60. The user can apply a push to the support seat 60 by leaning back and swinging the head up and down. When the spring insert 59 is applied, it further retracts into the support seat 60 under the abutment of the insertion groove 58, and then completely disengages from the insertion fit with the insertion groove 58, thus realizing the support seat 60. The vertical angle can be adjusted. After the adjustment is completed, the pusher 54 is released, and the pusher 55 and spring insert 59 are reset under the action of the spring. During use, the two adjustments can be distinguished by the indentation of the rotating wheel 52 and the protrusion of the pusher 54, which makes it easy to use.

[0046] Referring to Figures 1-11, the support base 60 includes a support frame located at the front end and fitting against the headrest, and a rotating plate located at the rear end and rotatably connected to the connecting seat 43. A connecting rod 61 is connected between the rotating plate and the connecting seat 43. The connecting rod 61 is fixedly connected to the support base 60 and rotatably connected to both connecting seats 43. The headrest is bound or fixed to the front end of the support base 60, and the user's neck abuts against the headrest, while the head abuts against the front end of the support base 60. With the connection of the connecting rod 61, the connecting seat 43, and the support base 60, the support base 60 can swing up and down, thereby enabling the support base 60 and the headrest to provide support for the user's head and neck.

[0047] Working process or usage method:

[0048] 1. The user sits on the seat 10 with their head against the front surface of the support seat 60. The height of the support seat 60 is adjusted at the guide rail 30, and the tilt of the support seat 60 is adjusted at the sliding frame 40. Specifically, by pushing the two rotating wheels 52 to rotate, the user controls the insertion rod 45 located in the insertion block 41 to retract inward, thus disengaging the insertion rod 45 from the insertion hole 32. The user can then push the rotating wheels 52 to move the sliding frame 40 up and down, thereby causing the support seat 60 connected to the sliding frame 40 to move up and down synchronously. Adjustments can be made according to the user's preference during this movement. Afterward, the rotating wheels 52 are released, and with the connection of the torsion spring 50, the insertion rod 45 is pushed back to its original position. The user can then slightly push the sliding frame 40 up and down to insert the insertion rod 45 into the corresponding height of the insertion hole 32 for adjustment. Similarly, by pushing the push block 54, the user can move the push plate 55... When the spring insert 59 is squeezed, and the spring insert 59 is engaged with the insertion slot 58, the support base 60 is pushed to swing up and down as the user's head moves up and down. After adjustment, the spring insert 59 is reset and inserted back into the insertion slot 58 to achieve positioning by releasing the push plate 55.
