Specific embodiment

In the following, the utility model is further described in each preferred embodiment in conjunction with shown in each attached drawing.

The location structure of uncapping of hydraulic cushion squelch type meal furnace is described in further detail below in conjunction with shown in each attached drawing.

Referring to 1 to Fig. 7, in this example, design production is suitable for the location structure of uncapping of hydraulic cushion squelch type meal bell, institute State hydraulic cushion squelch type meal furnace, including meal furnace body 1, lid 2, connector 3 and buffering silencing apparatus 4；The connector 3 wraps Include shaft 32 and the linking arm being connected as one with shaft 32 30；The connector 3 is solid by the card lid 33 at its 32 both ends of shaft It is scheduled on meal furnace body 1, the fixing axle 39 that shaft 32 can be fixedly connected in the inner, with card lid 33 around position rotates；Lid 2 and connector 3 linking arm 30 is fixedly connected；The buffering silencing apparatus 4 is mounted in the shaft 32 of connector 3, is located at two fixing axles 39 Between；The buffering silencing apparatus includes sub- axis 41, mother's axle 42 and tubular shell 43, spring 44 and hydraulic bjuffer 45；It is described Sub- axis 41 and hydraulic bjuffer 45 are mounted on the both ends in tubular shell 43, and the mother's axle 42 is mounted on sub- axis 41 and hydraulic cushion Between device 45, it is connected as one；When the lid open or close, the sub- axis 41 for buffering silencing apparatus is not rotated, tubular shell 43 rotate with shaft 32, and mother's axle 42 is moved left and right along the axial line of turbotype structure, stretch or squeeze the spring being coupled 44, it drives hydraulic bjuffer 45 to discharge thrust or resistance, is uncapped or buffered with power-assisted and close lid.

Location structure of uncapping is mounted on buffering silencing apparatus, including 5, first pairs of positioning rollers 6 of arc-shaped Location resilient piece With second pair of positioning rollers 7, the tubular shell around sub- axis one end nearly nozzle 430 at, be respectively set there are two penetrate through its The one-shaped slot 432 of shell wall, first pair of positioning rollers are distinguished in installation slotted eye, first pair of positioning rollers axial line and pipe The axis parallel of shape shell, the axle center connecting line L of two positioning rollers pass through the axle center O of tubular shell；The tubular shell The shell wall of nozzle 430 be provided with sagging concave station 431, the arc-shaped Location resilient piece 5 is on concave station 431, described first Arc-shaped 5 lower section of Location resilient piece is tightly coated on to positioning rollers；The cambered surface of first pair of positioning rollers is higher by tubular The inner wall of the nozzle 430 of shell；Have on the shell wall of sub- axis 41 in the tubular shell a pair of one-shaped recessed Slot 410, second pair of positioning rollers 7 are embedded in groove 410, and the cambered surface of second pair of positioning rollers 7 is higher by sub- axis 41 Shell wall, the axis parallel of second pair of positioning rollers 7 axial line and tubular shell, the axle center connection of two positioning rollers Line H passes through the axle center O of tubular shell.When cap closure, from the axle center connecting line L of first pair of positioning rollers and second pair of positioning The axle center connecting line H of roller bearing is not overlapped.

Referring to Fig. 6 and Fig. 7, when cap closure, from the positioning rolling of connecting line L to second pairs of the axle center of first pair of positioning rollers The angle of the axle center connecting line H of axis is dwell angle θ；When lid open it is vertical live when, the axle center connecting line L of first pair of positioning rollers with The angle of the axle center connecting line H of second pair of positioning rollers is fixed angles α, and the value of fixed angles α is determined according to the radius of positioning rollers； When lid stands position, the angle of lid and horizontal line M are the orientation angle β that uncaps；It can be adjusted by setting dwell angle θ and fixed angles α The whole orientation angle β that uncaps: such as when cap closure, dwell angle θ sets 80 °；When lid is opened, tubular shell will drive disposed within First pair of positioning rollers and elastic slice rotate together, when first pair of positioning rollers and second pair of positioning rollers interlock, positioning rolling Axis can jack up elastic slice, and elastic slice deformation, elastic force increases；When positioning rollers have crossed its maximum points of tangency, positioning rollers are by elastic slice Pressure is fallen after rise, and lid is pushed without external force at this time then founds firmly motionless, then orientation angle of uncapping at this time β=θ-α, the angle of orientation angle α in this example Degree is 5 °, i.e. 75 ° of angle of lid and horizontal line M whens hover.Arc-shaped Location resilient piece 5 be made of using elastic material, can root Its thickness and hardness are adjusted according to the weight of lid until can be vertical firmly motionless by lid.

On the basis of the above embodiments, one or more pairs of positioning rollers can be installed again on sub- axis, according to angle above-mentioned It spends setting method according to need, lid opening is made to be erected at different angle.

Embodiment described above only expresses preferred embodiments of the present invention, and description is more specific and detailed Carefully, but it should not be understood as limiting the scope of the patent of the utility model；It should be pointed out that for the general of this field For logical technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these are all Belong to the protection scope of the utility model；Therefore, all equivalents and modification done with the utility model claims range, It should belong to the covering scope of the utility model claims.
