Description

Technical Field

[0001] The present application relates to the technical field of seats, and in particular to a cover-type seat installation structure. Background Art

[0002] After the seat structure is built, it is usually necessary to wrap the seat cover and filler on the outside before proceeding to the next step. However, at present, the seat cover needs to be sewn to the structure frame through multiple pieces of cloth corresponding to different positions, which makes the seat production process more complicated. In the production of some other seats, attempts have been made to fit the one-piece all-inclusive seat cover, but the one-piece seat cover is limited by the installation method. The seats that can be assembled in this way are all straight-tube chair backs. For gaming chairs and other seats with recessed parts on the back or other special shape restrictions, they cannot be installed by fitting. Utility Model Content

[0003] In order to install a seat cover for a seat with a recessed inward shape, the present application provides a cover-type seat installation structure.

DETAILED DESCRIPTION

[0017] The present application is further described in detail below in conjunction with the accompanying drawings.

[0018] The present application embodiment discloses a cover-type seat installation structure, referring to Figure 1, including a structural frame 100, and a seat cover 110 for being mounted on the structural frame 100. A cover rod 111 needs to be provided on the structural frame 100. The specific shape of the cover rod 111 depends on the shape of the entire seat. For example, the middle part of the cover rod 111 is curved. After the seat cover 110 is installed, part of the seat cover 110 will be matched with the curved part to form a concave mechanism. Specifically, the seat cover 110 is provided with a connecting ring 112 for being mounted on the cover rod 111. The connecting ring 112 is sewn on the inner side of the seat cover 110. In this embodiment, the seat cover 110 is an integrally formed arrangement with a zipper on the side for easy installation and removal.

[0019] Reference Figure 1 , Figure 2 When the seat cover 110 is put on the structural frame 100, the connecting ring 112 will be inserted from the end of the sleeve rod 111. As the seat cover 110 is put on, the connecting ring 112 will move along the shape of the sleeve rod 111. When it moves to a specified position, for example, at the curved part ( Figure 1 The seat cover 110 is in a vertical state and is only used for illustration). A recessed portion will be formed on the seat by pulling to facilitate the installation and use of the integrated seat cover 110.

[0020] Reference Figure 2 , Figure 3 In actual use, the chair cover 110 will be subjected to external forces such as being pulled by the user's back. In order to keep the connecting ring 112 at a predetermined position without displacement, a limiting protrusion 120 is provided on the sleeve rod 111 in this embodiment for limiting the connecting ring 112 in its length direction.

[0021] The connecting ring 112 is located between two axially adjacent limiting protrusions 120 to form a limit in the length direction of the sleeve rod 111. The sleeve rod 111 is a hollow structure, and the sleeve rod 111 has a plurality of limiting grooves 121 along the circumferential direction for the limiting protrusions 120 to slide, and an elastic member for driving the limiting protrusions 120 to retreat is arranged in the limiting grooves 121. Specifically, the limiting groove 121 is arranged along the radial direction of the sleeve rod 111, and the elastic member is a return spring 122. The return spring 122 is sleeved on the outside of the limiting protrusion 120 and is located in the limiting groove 121. A limiting block 123 in the limiting groove 121 is arranged on the outer wall of the limiting protrusion 120. One end of the return spring 122 is pressed against the limiting block 123, and the other end is fixed on the inner wall of the limiting groove 121. The return spring 122 can make the limiting protrusion 120 have a tendency to retreat into the limiting groove 121. In this way, in the process of sleeve-mounting the connecting ring 112, the limiting protrusion 120 is located in the sleeve rod 111 and will not affect the connecting ring 112.

[0022] A driving member for driving the limiting protrusion 120 to protrude outward is provided on the sleeve rod 111. After the connecting ring 112 moves to the specified position, the limiting protrusion 120 is made to protrude outward by the driving member. In this embodiment, the driving member includes a driving bar 130 that moves along the extension direction of the sleeve rod 111, and a driving column 131 connected to one end of the driving bar 130 and threadedly connected to the inside of the sleeve rod 111. The driving bar 130 is inserted into the sleeve rod 111, and the driving column 131 is linear. At the same time, the end of the sleeve rod 111 is also linear, and the two are threadedly connected. Since the rest of the sleeve rod 111 may be of different shapes, the rest of the driving bar 130 is made of a flexible material, such as polyethylene or resin. By twisting the driving column 131, the driving bar 130 can be moved in the sleeve rod 111. The moving distance is short, and the limiting protrusion 120 can be lifted.

[0023] The specific lifting method is that a ball 132 for contacting the limiting protrusion 120 is provided on the driving bar 130, and in this embodiment, the driving column 131 and the driving column 131 are rotatably connected, so that when the driving column 131 rotates, it can maintain a good contact effect. In order to cooperate with the limiting protrusion 120, the contact surface 133 of the limiting protrusion 120 located at the inner end of the sleeve rod 111 is used to contact the ball 132.

[0024] Reference Figure 4 The driving bar 130 moves in a pulling manner, and a pulling spring 140 is connected to the end away from the driving column 131. When the driving column 131 moves, the driving bar 130 moves outward. The pulling spring 140 can keep the driving bar 130 in a straight state and can also reset the driving bar 130 later.

[0025] The principle of the embodiment of the present application is: first, the connecting ring 112 is sleeved on the end of the sleeve rod 111, so that the chair cover 110 is sleeved on the structural frame 100. At this time, the connecting ring 112 will move along the length direction of the sleeve rod 111. The connecting ring 112 cooperates with the shape of the sleeve rod 111 to form a recess or other specific pulling state.

[0026] At this time, when the connecting ring 112 moves to a predetermined position, a hole is reserved in the seat cover 110, which can cooperate with the screwing of the driving column 131 to make the driving bar 130 move outward for a certain distance in the sleeve rod 111. At this time, the ball 132 will abut against the inclined surface of the limiting protrusion 120 to form a resistance effect. The limiting protrusion 120 will move forward along the radial direction and protrude from the outer wall of the sleeve rod 111, forming a limit on both sides of the connecting ring 112.

[0027] When the seat cover 110 needs to be removed, the driving column 131 moves in the reverse direction, and the protrusion will move away from the limiting protrusion 120. At this time, the reset spring 122 and the pulling spring 140 reset the limiting protrusion 120, releasing the restriction on the connecting ring 112, and the connecting ring 112 can be removed.

[0028] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
