Abstract

The invention belongs to the technical field of chairs and in particular relates to a novel rotator mechanism of a rotating chair. The novel rotator mechanism comprises bolts, a rotator mechanism, a positioning tooth, a fixed tooth holder, a thrust ball bearing, a rotating shaft, a deep-groove ball bearing, a spring and an operating arm. The invention is characterized in that the operator's chair is fixedly arranged on the bed of the rotator mechanism through the bolts; the rotating shaft is fixedly connected on the bed through the bolts; the thrust ball bearing, a spacer, the deep-groove ball bearing and a check ring are arranged between the fixed tooth holder and the rotating shaft; the lower end of the rotating shaft is fastened with a nut through a pin; the positioning tooth is inserted in the fixed tooth holder; and the operating arm is connected with the positioning tooth through a pin shaft. Through the novel rotator mechanism, an operator on a special vehicle can rotate the chair 360 degrees and firmly fix the chair in any of thirty positions in the circumferential direction without the risk of swash. The novel rotator mechanism solves the problem that the chair swashes due to the gap resulting from cylindrical pin positioning and can not rotate smoothly, is a preferred and ideal rotating chair mechanism for special vehicle manufacturers, and is well accepted by users.

Description

A kind of swivel mechanism of novel rotary seat

Technical field:

The invention belongs to the chair technical field, be specifically related to a kind of swivel mechanism of novel rotary seat.

Background technology:

At present, require the operator can multi-faceted operating instrument instrument on the special vehicle, require the operator seat can 360 degree rotations; Arbitrary stationkeeping, still, the rotational structure great majority of the rotary seat that uses on the special vehicle now are to adopt traditional rotating as ball with steel ball; Be the structure with the cylinder pin hole location, the gapped seat that causes in cylinder pin hole location of this structure rocks, and when long-time the use; There is the not smooth phenomenon of rotation that generation is often arranged; Like this, being difficult to satisfy the special vehicle operator can multi-faceted operating instrument instrumentation, causes work inconvenience.

Summary of the invention:

The purpose of this invention is to provide a kind of employing by duplex bearing rotation, gear shaping formula flank location structure, rotatable 360 degree of seat, arbitrary position of circumferential 30 positions does not have the swivel mechanism of a kind of novel rotary seat of location, gap, to overcome above-mentioned deficiency.

The objective of the invention is to realize by following technical scheme:

A kind of swivel mechanism of novel rotary seat; By bolt, swivel mechanism, positioning teeth, fixedly toothholder, thrust ball bearing, spacer, S. A., pin, nut, cover, deep groove ball bearing, back-up ring, seat, spring, bearing pin, motion arm, journal stirrup, cover are formed; It is characterized in that: operator seat is installed on the seat of swivel mechanism by bolt; S. A. by bolted connection fixing present on, fixedly installed thrust ball-bearing casing, spacer, deep groove ball bearing, back-up ring between toothholder and the S. A., the S. A. lower end is fastenedly connected by pin and nut; Installation sleeve and be fixed as one on seat one side with seat; Bearing pin is installed in the cover, and installing and locating tooth on the bearing pin, positioning teeth insert fixedly in the toothholder tooth; Motion arm passes through bearing pin to be installed on the present journal stirrup, and motion arm is connected with positioning teeth through bearing pin, connects to form a kind of swivel mechanism of novel rotary seat on cover is present through bolt; The tooth of said positioning teeth and fixedly toothholder for closely cooperating; Said positioning teeth has three teeth; Said fixedly toothholder is the border toothing, has 30 teeth.

Advantage of the present invention is:

The present invention is mainly used in the rotating mechanism on the rotatable seat of operator on the special vehicle, adopts by duplex bearing rotation, gear shaping formula flank location structure, realizes steadily rotation; Location, no gap provides seat 360 degree rotations, realizes arbitrary location positioning of circumferential 30 positions; Fixation does not have and rocks; Solved the gapped seat that causes in cylinder pin hole location and rocked, and when long-time the use, the not smooth problem of rotation has been arranged; Be the swivel mechanism of first-selected, the desirable a kind of novel rotary seat of each special vehicle producer, can receive user's favorable comment surely.

The specific embodiment:

Embodiment:

Like Fig. 1-shown in Figure 5; The swivel mechanism of a kind of novel rotary seat of the present invention; Be by operator seat 1,

bolt

2,14,16, swivel mechanism 3, positioning teeth 4, fixedly toothholder 5, thrust ball bearing 6, spacer 7, S. A. 8, pin 9, nut 10, cover 11, deep groove ball bearing 12, back-up ring 13, seat 15, spring 17,

bearing pin

18,19, motion arm 20, journal stirrup 21, cover 22 are formed; It is characterized in that: operator seat 1 is fixedly mounted on the seat 15 of swivel mechanism 3 by bolt 2; S. A. 8 is fastened on the seat 15 by bolt 16, fixedly installed thrust ball-bearing casing 6, spacer 7, deep groove ball bearing 12, back-up ring 13 between toothholder 5 and the S. A. 8, and S. A. 8 lower ends are fastenedly connected by pin 9 and nut 10; Installation sleeve 22 and be fixed as one on seat 15 1 sides with seat 15; Bearing pins 18 are installed in the cover 22, and installing and locating tooth 4 on the bearing pin 18, positioning teeth 4 insert fixedly in toothholder 5 teeth; Motion arm 20 is installed through bearing pin 19 on present 15 the journal stirrup 21, and motion arm 20 is connected with positioning teeth 4 through bearing pin 18, and cover 11 is fixed to be present through bolt 14 and connected to form a kind of swivel mechanism of novel rotary seat on 15; The tooth of said positioning teeth 4 and fixedly toothholder 5 for closely cooperating; Said positioning teeth 4 has three teeth; Said fixedly toothholder 5 is the border toothing, has 30 teeth.

Embodiment 1:

As shown in Figure 1, operator seat 1 is to be installed on the seat 15 of swivel mechanism 3 through bolt 2, realizes 360 degree rotations, circumferential 30 location positioning.

As shown in Figure 2, the present invention structurally is divided into rotating part (the first half) and fixed part (the latter half).Operator seat 1 is to be fixed on the seat 15 of swivel mechanism 3 through bolt 2; S. A. 8 is fastened on the seat 15 through bolt 16; S. A. 8 is installed in fixedly on the toothholder 5 through deep groove ball bearing 12, spacer 7 and thrust ball bearing 6; S. A. 8 upper ends are through back-up ring 13 axial limitings, and S. A. 8 lower ends are fastenedly connected by nut 10 and pin 9; Positioning teeth 4 is installed in the cover 22 through bearing pin 18, and cover 22 is mounted on the seat 15, and with seat 15 be one, positioning teeth 4 is through the pressure fixing toothholder 5 of spring 17, realization is to rotational fixation; Motion arm 20 is installed through bearing pin 19 on present 15 the journal stirrup 21, and motion arm 20 1 ends are used for operation, the other end be connected with positioning teeth 4 through bearing pin 18.When an end of stepping on motion arm 20, the other end of motion arm 20 is stirred positioning teeth 4 through bearing pin 19 and is up moved, positioning teeth 4 and the fixedly teeth groove disengagement of toothholder 5, and the first half of rotating mechanism can rotate freely by 360 degree through bearing; Unclamp operation arm 20, positioning teeth 4 be down motion under the returning place force effect of spring 17, positioning teeth 4 insert fixing toothholder 5 teeth groove in; Cover 11 is through on the bolt 14 fixing present 15, and cover 11 mainly works to block the protection inner structure.

As shown in Figure 3 because the flank of tooth of positioning teeth 4 and fixedly the flank of tooth of toothholder 5 be domatic, under the returning place force effect of spring 17, the tooth of positioning teeth 4 and fixedly the tooth of toothholder 5 closely cooperate, realizes that no gap locatees.

Like Fig. 4-shown in Figure 5, positioning teeth 4 has three teeth, and fixedly toothholder 5 is the border toothing, has 30 teeth, can realize that circumferential 30 diverse locations are spacing.
