Problems solved by technology

[0004] However, these structures are either simple in design, single in function and mediocre in effect, unable to arouse the interest of consumers; or they are complex in design and functionally meet the needs of consumers, but the more complex structure makes the manufacturing cost high and is also prone to damage , and does not meet the market demand

Embodiment 1

[0066] Such as Figure 1-8 As shown, the base plate 1 of the adjustable forward-tilting swivel chair base is a one-piece cast iron stamping and forming, and the whole is horizontally arranged. A lifting wrench 7 and an adjustable tilt wrench 8 are respectively arranged on both sides of the chassis base 1 .

[0067] The middle plate 2 is installed above the chassis base 1 through the tilting axis Q; the tilting axis Q hinges the middle plate vertical wall 2. The forward tilting plate 3 is fitted on the top of the middle plate 2 through the forward tilting middle axis P'. The forward tilting pivot axis P' is hinged to the forward tilting plate vertical wall 3.b of the forward tilting plate 3 and the middle plate vertical wall 2.b of the middle plate 2.

[0068] The front end of the chassis base 1 is horizontally fitted with a tilting shaft Q. The middle part of the chassis seat 1 is the base middle plate 1.a. Open the tilting axis hole 1.a.1 of the base plate on the middle p...

Embodiment 2

[0087] Such as Figure 9-22 As shown, the base plate 1 of the adjustable forward-tilting swivel chair base is a one-piece cast iron stamping and forming, and the whole is arranged horizontally. The main body is the middle base plate 1.a, and the two sides of the base plate 1. A base plate vertical wall 1.b.

[0088] The middle plate 2 is installed above the chassis base 1 through the tilting axis Q; the tilting axis Q hinges the middle plate vertical wall 2. The forward tilting plate 3 is installed above the middle plate 2 through the forward tilting bottom rotating shaft P. The forward tilting bottom rotating shaft P is hinged to the forward tilting plate vertical wall 3.b of the forward tilting plate 3 and the base plate vertical wall 1.b of the chassis base 1 .

[0089] Each base plate vertical wall 1.b is sequentially provided with a base plate tilt pin hole 1.b.1, a base plate rotation axis hole 1.b.2, and a base plate forward tilt axis hole 1.b.3 from back to front. A...

Embodiment 3

[0108] This example Figure 23 Shown, substantially identical with embodiment 2, difference is:

[0109] The forward tilting plate 3 is fitted on the top of the middle plate 2 through the forward tilting middle axis P'. The forward tilting pivot axis P' is hinged to the forward tilting plate vertical wall 3.b of the forward tilting plate 3 and the middle plate vertical wall 2.b of the middle plate 2.

[0110] The middle plate 2 is provided with a middle plate forward tilting intermediate shaft hole 2.6.3', which is used to install the forward tilting intermediate shaft P'. The forward tilting axis P' passes through the forward tilting axis hole 1.b.3' of the base plate vertical wall 1.b of the base plate 1, and hinges the forward tilting plate 3 and the middle plate 2 so that the forward tilting plate 3 can move forward Tilting the axis of rotation P' is the axis of rotation.

[0111] The design of other places remains unchanged, adjust the distance between the large holes ...

Abstract

The invention discloses a swivel chair base capable of leaning forward in an adjustable mode. A swivel chair supporting rod is installed through a swivel chair rod hole in a subbase, an intermediate plate is installed above the subbase in a matched mode through a leaning rotation shaft, and the leaning rotation shaft is hinged to the vertical wall of the intermediate plate and the vertical wall of the subbase; a forward leaning plate is installed above the intermediate plate in a matched mode through a forward leaning bottom rotation shaft or forward leaning middle rotation shaft, and the forward leaning bottom rotation shaft is hinged to the vertical wall of the forward leaning plate and the vertical wall of the subbase; the forward leaning middle rotation shaft is hinged to the vertical wall of the forward leaning plate and the vertical wall of the intermediate plate. The swivel chair base and a chair back can lean forward simultaneously in a matched mode so as to fit the back, waist and whole pelvis of people who sit on a chair and better accord with human engineering; people feel more comfortable. The design can improve the practicality of the product, meet the requirements of consumers, and facilitate market expansion and product upgrading for enterprises.

Description

technical field [0001] The invention relates to the technical field of swivel chairs in the furniture industry, in particular to a swivel chair base with adjustable forward tilt. Background technique [0002] A swivel chair is a common piece of furniture. Existing swivel chairs can generally rotate horizontally and adjust height up and down. There are also some swivel chairs that can adjust the recline of the chair back. In particular, some swivel chairs can also ensure the tilting rocking motion of the chair back to match the posture of the human body, or to match the position of the center of gravity of different sitting postures. However, the structures and effects of various current swivel chairs are relatively single, and do not simultaneously satisfy multiple functions and human needs. [0003] For example, the design scheme of the Xiaoyao structure with the patent number DE202011002235U1 is to ensure that the seat plate can move forward and backward within a certai...
