Abstract
The present invention essentially discloses a kind of adjusting device of swivel chair, comprise base, base is hinged with mobile, mobile is provided with tubular spring regulating device, spring regulating device, mobile, base by pinned connection together, a side handle is provided with in spring adjustment structure, the degree of compression of side handle connection for transmission mechanism regulating spring, transmission mechanism is formed primarily of rack-and-pinion, because user's both hands are usually at side during use, so can the spring degree of very convenient regulating swivel chair by side handle, even if user also can the comfort level of regulating swivel chair when doing reclining backrest.
Description
Technical field
The present invention relates to the adjusting device to swivel chair.
Background technology
At present, much use swivel chair in office furniture, because it moves flexibly, the parent sitting the comfortable clerical workforce of being subject to of sense looks at, and wherein a lot of swivel chair has spring regulating device to carry out the seat sense of regulating swivel chair.On April 18th, 2007, the CN2889011Y Chinese invention of bulletin disclosed a kind of Revolving chair adjusting device, mainly include base, being hinged with in the middle of base can base middle cover in relative rotation, base middle cover connects gas bar, spring regulating device is provided with in base middle cover, so when swivel chair does reclining campaign, base middle cover keeps static because connect gas bar, base rotates because be articulated and connected to produce, thus Compress Spring, spring provides elastic force to reach comfortable seat sense, and the regulating spring degree of compression mainly use hand-screw dynamic pressure tubular upper cover on spring, screw thread is provided with in upper cover, realize upper cover by threads turn to move up and down, thus reach the object of regulating spring compression, but this adjusting device is not too convenient, because the dead ahead of adjusting device bottom swivel chair, during swivel chair static adjustment, people needs to bend over to go to touch upper cover with hand, even to leave swivel chair to squat down adjustment, and this device is when clerical workforce does reclining campaign to chair, whole people is leans back, both hands reach dead ahead bottom swivel chair substantially, do not reach the object regulating comfort level.
Summary of the invention
The technical issues that need to address of the present invention are, provide a kind of adjusting device of swivel chair, solve user's inconvenience when the spring-compressed of regulating swivel chair is spent, and cause not reaching the problem of well sitting sense comfort level.
Technical scheme of the present invention is: a kind of adjusting device of swivel chair, comprise base, base intermediate lateral is hinged with mobile, mobile is provided with spring regulating device, described spring regulating device comprises a cylindrical body, described cylindrical body axle center is longitudinally interspersed with a bearing pin and mobile, cylindrical body and base is connected, spring is provided with in described cylindrical body, it is characterized in that: described spring regulating device also comprises a side handle, described side handle is a multidiameter, and side handle taper end is connected with the transmission mechanism of the regulating spring degree of compression.
Preferably, described mobile is provided with support chip, and support chip has perforation, and the taper end of side handle is through perforation connection for transmission mechanism, and support chip can well support-side handle.
Preferably, described transmission mechanism is provided with gear, and the flank engagement assembling of wheel and rack, all the other 3 longitudinal side-fit of tooth bar are installed in slideway, and be fixed in mobile bottom slideway, tooth bar just slides in slideway by gear driven.
Preferably, described gear centre is provided with centre bore, and side handle taper end is inserted and is fixed in centre bore, and rotating side handle like this just can driven gear, and then band carry-over bar moves up and down.
Preferably, described tooth bar top is fixed with spring bottom bracket, and spring bottom bracket is placed with spring, and spring top side pressure has spring bracket.
Preferably, the face of described spring bracket holddown spring is provided with annular groove, can prevent spring from laterally departing from spring bracket.
Preferably, described side handle butt end is provided with anti-slip tank around outer surface, can allow operate convenient, laborsaving.
After adopting technique scheme, tool of the present invention has the following advantages: this adjusting device is provided with a side handle, side handle connection for transmission mechanism regulating spring, because side handle extends in the side of swivel chair, the both hands of user hang down just tangible to handle naturally, by the degree of compression of rotary side handle just adjustable springs, even if doing reclining campaign, when whole people's leans back, hand still can get at side handle very easily at side and regulate, thus allows swivel chair reach oneself comfortable seat sense.
Accompanying drawing explanation
Accompanying drawing 1 is contained in the schematic diagram on swivel chair seat board for this adjusting device;
Accompanying drawing 2 is the schematic diagram of this adjusting device front view;
Accompanying drawing 3 is the close-up schematic view of adjusting device transmission mechanism.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
As shown in Figure 1 to Figure 3, adjusting device of the present invention is fixed with in seat board 1 center of swivel chair, adjusting device comprises base 2, it is hinged with mobile 3 that base 2 intermediate lateral is installed with pin 32, mobile 3 is inserted with gas bar 5, gas bar 5 is fixed with foot rest 6, there is a spring regulating device 4 in described mobile 3 near swivel chair front place, spring regulating device 4 comprises a cylindrical body 47, spring 44 is provided with in cylindrical body 47, cylindrical body 47 axle center is longitudinally interspersed with bearing pin 21 mobile 3, cylindrical body 47 and base 2 link together, a support chip 31 is also had to fix with mobile 3 at the transverse side of spring regulating device 4, support chip 31 is provided with perforation, side handle 41 is a multidiameter, wherein thinner end is specifically told about below through described perforation connection for transmission mechanism 48(transmission mechanism 48 operation principle) carry out regulating spring 44, the butt end of side handle 41 is provided with anti-slip tank 411, more laborsaving when making to rotate.
Spring regulating device 4 mainly includes spring 44 and transmission mechanism 48 as can be known from Fig. 3, transmission mechanism 48 is provided with gear 42, there is centre bore 421 at gear 42 center, the taper end of side handle 41 is inserted centre bore 421 and is fixed, thus realize the connection of side handle 41 and transmission mechanism 48, gear 42 engages with tooth bar 43 and installs, tooth bar 43 all the other 3 longitudinal sides except the flank of tooth are fitted in slideway 46, slideway 46 bottom and mobile 3 are fixed, the top of tooth bar 43 is fixed with spring bottom bracket 45, spring bottom bracket 45 is placed spring 44, spring 44 is pressed with spring bracket 49, spring bracket 49 and spring 44 contact surface are provided with annular groove 491, prevent spring 44 from laterally departing from, when regulating, user's rotating side handle 41, thus the rotation of driven gear 42, gear 42 and tooth bar 43 engaged transmission, tooth bar 43 just moves up and down in slideway, when moving up and down, spring bottom bracket 45 can compress or trip spring 44, thus reach the object of regulating spring 44 degree of compression.
Below only just the present invention preferably example be described, but can not be interpreted as it is limitations on claims.The present invention not only limits to and above example, its concrete structure allows to change, be polygonal column construction if side handle can be cross section, those skilled in the art can make various change and distortion according to the present invention, only otherwise depart from spirit of the present invention, the scope that claims of the present invention define all should be belonged to.
