Description
Technical field
The utility model relates to a kind of floor spring, the floor spring that particularly a kind of structure is simplified.
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.One way valve and safety valve according to existing technology piston are splits, and structure is more loaded down with trivial details, and one way valve is to utilize the steel ball sealing, and leaks easily, and sealing performance is relatively poor; Safety valve is to utilize steel ball, and is spring sealed.Steel ball is located on the safety valve, and volume is bigger.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of floor spring simple in structure is provided.
For solving the problems of the technologies described above, technical scheme provided by the utility model is: a kind of floor spring simple in structure, comprise valve body, and in the valve body chamber, be provided with oil cylinder and Transmission Room; Be provided with hydraulic mechanism in the described oil cylinder, the oil cylinder front end is provided with protecgulum, is provided with transmission mechanism in the described Transmission Room, and transmission mechanism is provided with the wheel shaft core that links to each other with door-hinge, is provided with the gland that sealing Transmission Room and cover are acquired a core at the Transmission Room upper wall; Described valve body, protecgulum, wheel shaft core, gland are formed a seal chamber, and described hydraulic mechanism comprises piston, connects the connecting rod of piston and transmission mechanism, the spring on the connecting rod; Be provided with annular oil circuit between valve body wall and the piston, this section valve body is provided with assigns the hydraulic fluid port of adjusting valve and communicating with oil circuit; Piston is provided with collection safety valve and the integrated integrating device of one way valve, and described safety valve is a device of forcing to protect at closing time floor spring internal construction function in external force, described one way valve be the control hydraulic oil flow to device.
Further: on the simple floor spring of said structure, described integrating device comprises steel ball, emergency valve seat, safety valve plug screw and the sealing ring that is socketed in integrating device neck end successively.Described transmission mechanism also comprise planker, down planker, be clipped in up and down planker and make the cam of locating behind the door-hinge rotational angle, the wheel shaft core retainer plate is connected under the planker on the planker; Between described planker up and down and the connecting rod is to flexibly connect.
Compared with prior art; floor spring simple in structure provided by the utility model; piston is provided with collection safety valve and the integrated integrating device of one way valve; described safety valve is a device of forcing to protect at closing time floor spring internal construction function in external force, described one way valve be the control hydraulic oil flow to device.The utility model changes the structure and the sealing means of safety valve, and split is made into disjunctor, and one way valve adopts the sealing of " O " type circle, is difficult for leaking, and is durable; Safety valve sealing steel ball is located in the emergency valve seat, has dwindled volume, it is impaired that piston is difficult for, safe and reliable, long service life.
Description of drawings
Fig. 1 is that vertical portion of the present utility model structure is shown view;
Fig. 2 is that the utility model transverse part structure is shown view;
Wherein 1 valve body, 2 protecgulums, 3 wheel shaft cores, 4 glands, 5 pistons, 6 connecting rods, 7 springs, 8 are adjusted planker on valves, 9 steel balls, 10 emergency valve seats, 11 safety valve plug screws, 12 " O " type circle, 13,14 times plankers, 15 cams.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model floor spring is further specified below in conjunction with the drawings and specific embodiments:
Shown in accompanying drawing 1-2, a kind of floor spring simple in structure comprises valve body 1, is provided with oil cylinder and Transmission Room in the valve body chamber; Be provided with hydraulic mechanism in the described oil cylinder, the oil cylinder front end is provided with protecgulum 2, is provided with transmission mechanism in the described Transmission Room, and transmission mechanism is provided with the wheel shaft core 3 that links to each other with door-hinge, is provided with the gland 4 that sealing Transmission Room and cover are acquired a core 3 at the Transmission Room upper wall; Described valve body 1, protecgulum 2, wheel shaft core 3, gland 4 formed a seal chamber, and described hydraulic mechanism comprises piston 5, connects the connecting rod 6 of piston and transmission mechanism, the spring 7 on the connecting rod; Be provided with annular oil circuit between valve body wall and the piston 5, this section valve body is provided with assigns the hydraulic fluid port of adjusting valve 8 and communicating with oil circuit; Piston 5 is provided with collection safety valve and the integrated integrating device of one way valve, and described safety valve is a device of forcing to protect at closing time floor spring internal construction function in external force, described one way valve be the control hydraulic oil flow to device."
