DETAILED DESCRIPTION

[0021] The utility model will be further explained in detail by examples in combination with the drawings, and the following examples are the explanation of the utility model, and the utility model is not limited to the following examples.

[0022] Referring to Figures 1-7 The iron art rotating dining chair includes a seat surface 1, a base 2 and a connecting mechanism 3. The upper and lower ends of the connecting mechanism 3 are connected with the bottom end of the seat surface 1 and the top end of the base 2 respectively. The seat surface 1 is horizontally and vertically rotatably arranged above the base 2 through the connecting mechanism 3.

[0023] The utility model discloses a seat surface 1 is installed on the base 2 through the connecting mechanism 3, so as to drive the seat surface 1 to rotate horizontally and vertically, thereby achieving the purpose of adjusting the angle of the seat surface 1. Therefore, the user can adjust the seat surface 1 to the appropriate position according to the own demand and the habitual sitting posture, so that the utility model can meet the demand of the user to rotate the dining chair seat surface 1 in the horizontal direction and the vertical direction.

[0024] Referring to Figures 2-4 The connecting mechanism 3 includes a bottom plate 31, a support plate 32, a lower rail piece 33 and an upper rail piece 34. The support plate 32 is horizontally rotatably arranged on the bottom plate 31. The lower rail piece 33 and the upper rail piece 34 are respectively provided with downward protruding circular arc-shaped lower rails 35 and upper rails 36. The lower rail piece 33 and the upper rail piece 34 are perpendicular to each other. The lower rail piece 33 is fixed on the support plate 32. The roller group 37 is arranged between the lower rail piece 33 and the upper rail piece 34. The lower ends of the roller group 37 slide left and right in the lower rails 35. The upper ends of the roller group 37 slide forward and backward in the upper rails 36.

[0025] The horizontal rotation connection between the support plate 32 and the bottom plate 31 realizes the horizontal rotation of the seat surface 1 on the base 2. Since the lower track 35 is in the shape of a circular arc, when the roller set 37 moves along the lower track 35, the seat surface 1 and the upper track 36 rotate in the vertical plane in the left-right direction as a whole while moving; when the roller set 37 moves along the upper track 36, the seat surface 1 and the upper track 36 rotate in the vertical plane in the front-rear direction as a whole while moving. Therefore, the seat surface 1 in the utility model can realize rotation at various angles in the vertical plane through the movement of the roller set 37 in the upper track 36 and the lower track 35, and the movement of the roller set 37 in the upper track 36 and the lower track 35 can be carried out simultaneously, thereby improving the convenience of angle adjustment of the seat surface 1.

[0026] Referring to Figure 3 , Figure 4 , the lower track 35 and the upper track 36 are both provided with two, the two lower tracks 35 are parallel to each other, the two upper tracks 36 are parallel to each other, and any one lower track 35 and any one upper track 36 are connected with the roller set 37.

[0027] The four roller sets 37 are arranged between the two upper tracks 36 and the lower track 35, thereby improving the stability of the connection between the upper track 36 and the lower track 35 through the roller set 37, reducing the risk of the seat surface 1 falling off the base 2 due to the fracture and damage of the roller set 37 when the seat surface 1 bears a large load, and improving the safety during use of the utility model.

[0028] Referring to Figure 5 , the roller set 37 includes a connecting rod 38 and four rollers 39, wherein two rollers 39 are rotatably arranged on the front and rear sides of the lower end of the connecting rod 38 and located in the lower track 35, and the other two rollers 39 are rotatably arranged on the left and right sides of the upper end of the connecting rod 38 and located in the upper track 36.

[0029] The upper and lower ends of the roller set 37 are both symmetrically provided with two rollers 39, which are rotatably arranged in the upper track 36 and the lower track 35, thereby improving the stability of the connection between the roller set 37 and the upper track 36 and the lower track 35, reducing the friction of the roller set 37 moving in the upper track 36 and the lower track 35 through the rollers 39, and reducing the risk of the roller set 37 being stuck in the upper track 36 and the lower track 35.

[0030] Referring to Figure 3 , Figure 6The support plate 32 has two locking mechanisms 4 symmetrically arranged on its left and right sides. Each locking mechanism 4 includes a sliding member 41, a pull rod 42, and a locking member 43. The sliding member 41 is slidably mounted on the support plate 32 and its upper end contacts the bottom end of the seat surface 1. The inner end of the pull rod 42 is rotatably mounted in the lower track member 33 via a ball pin. The locking member 43 has an L-shaped limiting hole 44 in which the pull rod 42 is inserted. The limiting hole 44 includes a vertical section 45 and a horizontal section 46. One end of the horizontal section 46 is connected to the upper end of the vertical section 45.

[0031] The angle of the seat surface 1 is fixed by the locking mechanism 4. When the unlocking operation is performed, the outer end of the pull rod 42 is operated to make the pull rod 42 rotate along the ball pin. The pull rod 42 moves in the limiting hole 44 on the snap-fit ​​part 43, driving the pull rod 42 from the horizontal section 46 to the vertical section 45 and moving downward. Thus, the sliding part 41 can move downward and separate from the seat surface 1. At this time, the angle of the seat surface 1 can be adjusted under the action of the connecting mechanism 3.

[0032] When locking, the operating lever 42 moves upward from the vertical section 45 of the limiting hole 44 into the horizontal section 46. At this time, the sliding member 41 moves upward so that its upper end abuts against the seat surface 1. The horizontal section 46 prevents the lever 42 from moving downward and causing the sliding member 41 to separate from the seat surface 1. The force between the sliding member 41 and the seat surface 1 fixes the seat surface 1. The seat surface 1 can be unlocked and locked by operating the lever 42. The user can also perform the unlocking and locking operations while sitting on the seat surface 1, thus having the advantage of simple operation.

[0033] See Figure 6 , Figure 7 The sliding member 41 is provided with a positioning rod 47 that slides up and down. The upper end of the positioning rod 47 extends from the top of the sliding member 41. A spring 48 is provided between the lower end of the positioning rod 47 and the sliding member 41 to drive the positioning rod 47 to move upward. The bottom end of the seat surface 1 is provided with a plurality of positioning holes 49 for the top of the positioning rod 47 to be inserted. The top of the positioning rod 47 and the positioning holes 49 are both truncated cones that fit together.

[0034] When the seat surface 1 is in the locked state, the sliding member 41 abuts against the seat surface 1, and the upper end of the positioning rod 47 is inserted into the corresponding positioning hole 49. The spring 48 is in a compressed state and cannot be compressed further. Therefore, the positioning rod 47 cannot move downward. The seat surface 1 is fixed by the action of the positioning rod 47 and the positioning hole 49, which improves the fixing effect of the locking mechanism 4 on the seat surface 1 and reduces the risk that the seat surface 1 will not lock well due to insufficient friction between the sliding member 41 and the seat surface 1.

[0035] When the seat surface 1 is in the unlocked state, the sliding piece 41 moves downward and separates from the seat surface 1, the upper end of the positioning rod 47 is still inserted into the corresponding positioning hole 49, the spring 48 is in the compressed state but can be further compressed, thus the positioning rod 47 can move downward, at this time, an external force is applied to the seat surface 1 to push the seat surface 1, since the top end of the positioning rod 47 and the positioning hole 49 are both mutually adapted and fitted frustocones, the seat surface 1 moves and pushes the top end of the positioning rod 47 out of the positioning hole 49, under the respective actions of the seat surface 1 and the spring 48, the top end of the positioning rod 47 repeatedly inserts into and comes out of the positioning holes 49 in the respective positions in the moving track of the seat surface 1, until the seat surface 1 is adjusted to the required position, at this time, the top end of the positioning rod 47 is inserted into the corresponding positioning hole 49, the sliding piece 41 is moved upward and abuts against the seat surface 1 by operating the pull rod 42, the spring 48 is compressed to the incompressible state, so that the seat surface 1 returns to the locked state.

[0036] The interaction between the positioning rod 47 and the positioning hole 49 can further enhance the locking effect of the locking mechanism 4 on the seat surface 1, without increasing the complexity of the operation of the locking mechanism 4.

[0037] The above described in the specification of the present application is only an example of the present application. The skilled in the art of the present application can make various modifications or supplements or adopt similar ways to replace the described specific embodiments, as long as it does not deviate from the content of the specification of the present application or exceed the scope defined by the claims, which shall belong to the protection scope of the present application.
