Description
Technical field
The utility model relates to consumer goods industries, particularly relates to the improvement of the adjustable seat in a kind of angle of lying.
Background technology
At present, for the chair back lie angle regulate seat have a lot, representative as State Bureau be called " angle regulator of infusion chair back plate " in the portion that on April 3rd, 2013 announces, application number is the document of " 201210563927.7 ", propose in this case and a kind ofly drive Pneumatic assembly thus the transfusion chair regulated the angle of lying of seat in a manual manner, this case has and regulates the advantages such as easy, stable.
But people find when reality uses, no matter be Pneumatic assembly or hydraulic package, all easily there is the phenomenons such as inefficacy in it, and this type of inefficacy pole is not easily discovered after a long time use; Therefore, very easily security incident occurs in use, bring great potential safety hazard to user, meanwhile, this type of seat also has the high defect of production cost.
Utility model content
The utility model, for above problem, proposes a kind of delicate structure, easy to use and with low cost, can effectively to the angle seat chair with adjustable of lying that danger is reported to the police during use.
The technical solution of the utility model is: chair leg, a pair back leg, pair of armrests, a seat support, a chair back and adjusting part before comprising a pair, before described in a pair, chair leg and back leg described in a pair divide the both sides, front and back that are located at described seat support and are all fixedly connected with seat support, the bottom of the described chair back is hinged on the side of described seat support near back leg, and handrail described in a pair is all fixedly connected on described seat support;
Described adjusting part comprises handwheel, gangbar, driven wheel, tooth bar, slide, crossbeam and connecting rod, the axle center of described handwheel is hinged on described handrail, described driven wheel to be articulated in below described seat support and consistent with the diameter of described handwheel, and the two ends of described gangbar are hinged on described handwheel and described driven wheel respectively; Described crossbeam is fixedly connected between front chair leg and back leg, described slide is fixedly connected on above described crossbeam, described tooth bar is slidably connected in described slide, described tooth bar to be positioned at below described driven wheel and to engage with described driven wheel, and the two ends of described connecting rod are hinged on tooth bar respectively away from one end of described front chair leg and chair back one end away from described front chair leg.
Described seat also comprises alarm assemblies, described alarm assemblies comprises dc source and LED light, described dc source and LED light are all fixedly connected on described front chair leg, described tooth bar and driven wheel are made up of conductive material and described slide and connecting rod are made up of insulating materials, described gangbar bottom is made up of conductive material and top is made up of insulating materials, be communicated with by wire between described dc source with described tooth bar, described LED light is communicated with by wire with the bottom of described gangbar.
Described handwheel is provided with insulated handle.
Snap close is provided with between described handwheel and handrail.
The pure theory of mechanics of pinching with traditional rack-and-pinion in the utility model bans the type of drive of pneumatic or hydraulic pressure of the prior art, has that reliability is high, the feature of long service life.Meanwhile, once LED light is extinguished during use, then represent that the chair back of this angle is insecure, thus remind user of service to change angle of back-rest to use, or maintenance intervention assembly re-uses.There is kind of a delicate structure, the feature that easy to use, with low cost, security is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1 is front chair leg, and 2 is back legs, and 3 is handrails, and 4 is seat supports, and 5 is chair back, and 6 is adjusting parts, 61 is handwheels, and 62 is gangbar, and 63 is driven wheels, and 64 is tooth bars, and 65 is slides, 66 is crossbeams, and 67 is connecting rods, and 7 is alarm assemblies, and 71 is dc sources, and 72 is LED lights.
Detailed description of the invention
The utility model as shown in Figure 1, chair leg 1, a pair back leg 2, pair of armrests 3, seat support 4, chair back 5 and adjusting part 6 before comprising a pair, before described in a pair, chair leg 1 is located at the both sides, front and back of described seat support 4 with back leg described in a pair 2 points and is all fixedly connected with seat support 4, the bottom of the described chair back 5 is hinged on described seat support 4 near the side of back leg 2, and handrail 3 described in a pair is all fixedly connected on described seat support 4;
Described adjusting part 6 comprises handwheel 61, gangbar 62, driven wheel 63, tooth bar 64, slide 65, crossbeam 66 and connecting rod 67, the axle center of described handwheel 61 is hinged on described handrail 3, described driven wheel 63 to be articulated in below described seat support 4 and consistent with the diameter of described handwheel 61, and the two ends of described gangbar 62 are hinged on described handwheel 61 and described driven wheel 63 respectively; Described crossbeam 66 is fixedly connected between front chair leg 61 and back leg 62, described slide 65 is fixedly connected on above described crossbeam 66, described tooth bar 64 is slidably connected in described slide 65, described tooth bar 64 to be positioned at below described driven wheel 63 and to engage with described driven wheel 63, and the two ends of described connecting rod 67 are hinged on tooth bar 64 respectively away from one end of described front chair leg 1 and the chair back 5 one end away from described front chair leg 1.
Described seat also comprises alarm assemblies 7, described alarm assemblies 7 comprises dc source 71 and LED light 72, described dc source 71 and LED light 72 are all fixedly connected on described front chair leg 1, described tooth bar 64 and driven wheel 63 are made up of conductive material and described slide 65 and connecting rod 67 are made up of insulating materials, described gangbar 62 bottom is made up of conductive material and top is made up of insulating materials, be communicated with by wire between described dc source 71 with described tooth bar 64, described LED light 72 is communicated with by wire with the bottom of described gangbar 62.Like this, when adjusting part runs, two or more empty teeth or broken teeth is there is on tooth bar or driven wheel, LED light will directly be extinguished, thus give user with one intuitively visual signal user is warned, thus effectively evaded the potential safety hazard that produces because adjusting part lost efficacy.
Described handwheel is provided with insulated handle.Thus effectively promote the security of seat.
Snap close is provided with between described handwheel and handrail.Thus carry out locked after the angular adjustment of the chair back puts in place.
