Description
Technical field
The present invention relates to a kind of floor spring, particularly a kind of multi-functional floor spring.
Background technology
The gate floor spring is mainly formed a hydraulic damping device by hydraulic oil, body, spring, piston.Power comes from the built-in compression spring of body, and spring force is by the piston drivening rod, and connecting rod drives the wheel shaft core, rotates thereby drive door-hinge, and the door-hinge location is by being socketed in contacting of cam and locating wheel on the wheel shaft core.In motion process, piston with transmission of power to hydraulic oil, hydraulic oil then oil circuit, the chamber, a body left side by offering on the body, flow to the right chamber of body through control valve.Adjust control valve, then can regulate the flow velocity and the flow of hydraulic oil, thus indirect regulation piston and movement of springs speed.And close the door is to drive the door rotation by the wheel shaft core, promote left at the following piston of the effect of back-moving spring, the piston drivening rod, connecting rod drives the wheel shaft core, and the wheel shaft core drives the door rotation, and door is closed automatically, therefore, control valve on the body is the speed of closing of regulating, by adjusting control valve, the effect of can obtain soon, closing the door at a slow speed.This shows that hydraulically the power of closing the door of spring is from the compression spring, the effect of closing the door then is to obtain by the flow of regulating hydraulic oil.Common floor spring door leaf reaches 90 ° of location only, and brute force is opened the door to fan and is collided sometimes; Each floor spring only provides a fixing strength of closing; Along with the variation hydraulic oil of weather has the phenomenon of expanding with heat and contract with cold, cause quick-fried body, leakage of oil; The client exists sometimes and uses external force to force the situation of closing the door in the process of using, and has destroyed the internal construction of floor spring, makes defectives such as floor spring inefficacy.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, and a kind of novel floor spring is provided, and has solved the problem that common floor spring is fragile, the life-span is short.
Realize that technical scheme of the present invention is: a kind of multi-functional floor spring, comprise valve body, in the valve pocket of valve body, be provided with planker, connecting rod, piston successively, have the valve body end of planker to be provided with gland, the valve body other end is provided with end cap; Be provided with annular oil circuit between described valve body wall and the piston, this section valve body is provided with assigns the adjustment valve of regulating the hydraulic-oil quantity size and the hydraulic fluid port that communicates with oil circuit, described piston also is connected with and prevents that hydraulic oil from expanding with heat and contract with cold and cause the micro-adjusting mechanism of quick-fried machine, leakage of oil, is socketed with the big spring that is connected with piston on the described micro-adjusting mechanism.
Further: on above-mentioned multi-functional floor spring, described micro-adjusting mechanism comprises adjusting rod, regulates to pull out and rub with the hands and adjusting nut, and adjusting nut is socketed in to regulate and pulls out in the stranding, and adjusting rod one end connects adjusting and pulls out stranding, and the other end connects piston.Described adjusting rod is a cavity structure, and inside is provided with small piston and the hairspring that is connected with small piston.
Further again: on above-mentioned multi-functional floor spring, described planker is divided into planker up and down, and the front end both sides between upper and lower planker are provided with locating wheel; The one-sided wheel shaft core retainer plate that runs through valve body wall and link to each other with door-hinge is connected on up and down on the planker, be socketed with on the described wheel shaft core between planker up and down can make door-hinge rotate 90 location when spending two to cam with can make door-hinge rotate the random positioned multidirectional cam in 140 degree backs.Described two are provided with the concave surface that makes door produce cushioning effect when reaching 70 ° to flank of cam.Described internal piston is provided with and prevents the external force pressure at closing time, the safety valve of protection piston.Described safety valve comprises steel ball, safety spring and set screw.
Compared with prior art, also be connected with on the piston of floor spring provided by the present invention and prevent that hydraulic oil from expanding with heat and contract with cold and cause the micro-adjusting mechanism of quick-fried machine, leakage of oil, be socketed with the big spring that is connected with piston on the described micro-adjusting mechanism.The dynamics of spring can be regulated, adopt existing floor spring structure can't reach these requirements, must change overall structure and connected mode through the research decision, described micro-adjusting mechanism is adjusting rod, regulates to pull out and rub with the hands and adjusting device of adjusting nut composition, only need regulate during adjusting the adjusting that is located at the end cap end pull out rub with the hands spring force just along with change finely tune out with just can having no boundary make the user fully satisfaction close a strength, make same floor spring be fit to different gate-widths, weigh.Described at built-in hairspring of adjusting rod and small piston, hydraulic oil expansion promotion piston moves in the chamber to the right when temperature is high, makes the oil pressure of hydraulic oil that enough spaces be arranged; Hydraulic oil was contracted in the built-in hairspring of adjusting rod and promotes small piston and move in the chamber left when temperature was low, made hydraulic oil fill up oil cylinder and made the oil pressure held stationary.The built-in safety valve of described piston uses external force to force at closing time, when the pressure that safety valve bears reaches certain value, opens rapidly, prevents that effectively external force from forcing at closing time, and piston is impaired.Blade both sides at cam are provided with the buffering concave surface, and concave surface produces the cushioning effect as bed course when door reaches 70 °, with lower because of as wind or door leaf and the wall damage that the excessive strength of opening the door causes such as push away by force suddenly.So entirely spring be difficult for impaired, safe and reliable, long service life.
