Summary of the invention
The technical issues that need to address of the present invention are, a kind of adjusting device of swivel chair is provided, and have solved user's inconvenience when regulating the spring degree of compression of swivel chair, cause not reaching the problem of good seat sense comfort level.
Technical scheme of the present invention is: a kind of adjusting device of swivel chair, comprise base, the 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 vertically is interspersed with a bearing pin mobile, cylindrical body and base is connected, be provided with spring in the described cylindrical body, it is characterized in that: described spring regulating device also comprises a side handle, described side handle is a multidiameter, and the thin end of side handle is connected with the transmission mechanism of the regulating spring degree of compression.
Preferably, described mobile is provided with support chip, and perforation is arranged on the support chip, and the thin end of side handle passes perforation and connects transmission mechanism, and support chip can well the support-side handle.
Preferably, described transmission mechanism is provided with gear, the flank engagement assembling of wheel and rack, and 3 vertical sides cooperations of all the other of tooth bar are installed in the slideway, and the slideway bottom is fixed in the mobile, and tooth bar just can slide in slideway by gear driven.
Preferably, described gear centre is provided with centre bore, and side handle is carefully held and inserted and be fixed in the centre bore, but just driven gear of rotating side handle like this, and then drive tooth bar and move up and down.
Preferably, fixedly there is the spring bottom bracket on described tooth bar top, is placed with spring on the spring bottom bracket, and the spring top is pressed with the spring bracket.
Preferably, the face of described spring bracket holddown spring is provided with annular groove, can prevent that spring laterally breaks away from the 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, the present invention has following advantage: this adjusting device is provided with a side handle, side handle connects the transmission mechanism regulating spring, because side handle extends in the side of swivel chair, user's both hands hang down just tangible to handle naturally, by rotating the just degree of compression of adjustable springs of side handle, even if doing the reclining campaign, in the time of whole people's leans back, hand still can get at side handle very easily at side and regulate, thereby allows swivel chair reach an own comfortable seat sense.
Description of drawings
Accompanying drawing 2 is the schematic diagram of this adjusting device front view;
Accompanying drawing 3 is the local enlarged diagram of adjusting device transmission mechanism.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
As shown in Figure 1 to Figure 3, fixedly there is adjusting device of the present invention seat board 1 center at swivel chair, adjusting device comprises base 2, it is hinged with mobile 3 that base 2 intermediate lateral are installed with pin 32, mobile 3 is inserted with gas bar 5, foot rest 6 is fixedly arranged on the gas bar 5, there is a spring regulating device 4 in described mobile 3 near place, swivel chair the place ahead, spring regulating device 4 comprises a cylindrical body 47, be provided with spring 44 in the cylindrical body 47, cylindrical body 47 axle center vertically are interspersed with bearing pin 21 mobile 3, cylindrical body 47 and base 2 link together, transverse side at spring regulating device 4 also has a support chip 31 fixing with mobile 3, support chip 31 is provided with perforation, side handle 41 is a multidiameter, wherein thinner end passes described perforation and connects transmission mechanism 48(transmission mechanism 48 operation principles and specifically tell about below) come regulating spring 44, the butt end of side handle 41 is provided with anti-slip tank 411, makes when rotating more laborsaving.
Spring regulating device 4 has mainly comprised 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 centers, the thin end of side handle 41 inserts centre bore 421 and fixing, thereby realization side handle 41 is connected with transmission mechanism 48, gear 42 is installed with tooth bar 43 engagements, tooth bar 43 all the other 3 vertical sides except the flank of tooth are fitted in the slideway 46, slideway 46 bottoms and mobile 3 are fixing, fixedly there is spring bottom bracket 45 on the top of tooth bar 43, place spring 44 on the spring bottom bracket 45, be pressed with spring bracket 49 on the spring 44, spring bracket 49 is provided with annular groove 491 with spring 44 contact-making surfaces, prevent that spring 44 laterally breaks away from, when regulating, user's rotating side handle 41, thereby the rotation of driven gear 42, gear 42 and tooth bar 43 engaged transmission, tooth bar 43 just moves up and down in slideway, and spring bottom bracket 45 can compress or trip spring 44 when moving up and down, thereby reaches the purpose of regulating spring 44 degrees of compression.
