Abstract
The utility model relates to a spring-oil damping hinge core, which comprises a casing, a telescopic rod and an offsetting spring, wherein one end of the telescopic rod is extended into one end of the casing in a sliding way, and the offsetting spring is arranged in the casing; the inner end of the telescopic rod is connected with an upper piston, an oil draining hole is arranged between both ends of the upper piston, and a seal assembly is arranged between the telescopic rod and the inside of an opening end of the casing; the upper end of the offsetting spring is provided with a lower piston, and damping oil is filled between the upper piston and the lower piston. In the process of the telescopic operation of the telescopic rod of the utility model, the damping oil is transferred through the oil draining hole between both ends of the upper piston, which has the damping effect, and particularly, the reset speed of the telescopic rod is delayed; when the telescopic rod is in the final stage of resetting, because the restoring force of the spring is decreased, force applied on the piston rod can be decreased along with the decrease of the restoring force of the spring, and the speed of a rod body can be reduced under the damping action of the damping oil; thus, the speed of a door is low at the time of closure and the muting operation in the process of closing the door and a hinge can be realized.
Description
Technical field
The utility model relates to a kind of hinge, specifically is a kind of spring-oil damping hinge core, and is main as the torsion elastic component in the hinge of being connected between door and doorframe or other fixture.
Background technology
The torsion elastic component of the trivial employing of existing hinge generally is a torque spring.Its shortcoming is because the keying of hinge all with torque spring position fulcrum, does not have pooling feature, causes door to produce very big noise when opening and closing (particularly closing), in the application life of reducing hinge, also crushes user's finger simultaneously easily.
Summary of the invention
The purpose of this utility model just provides a kind of spring-oil damping hinge core, to solve the pooling feature that do not have that prior art exists, cause door when opening and closing (particularly closing), to produce very big noise, the application life of reducing hinge, and the problem that crushes user's finger easily.
The technical solution of the utility model is: comprise housing, expansion link and back-moving spring, one end of expansion link slides and stretches into an end of housing, in housing, be provided with back-moving spring, it is characterized in that: the inner at described expansion link is connected with upper piston, between the two ends of this upper piston, be provided with the draining hole, between the inside of expansion link and shell nozzle end, be provided with black box; Be provided with lower piston in described back-moving spring upper end, between described upper piston and lower piston, be filled with damping oil.
Side face at described upper piston and lower piston is provided with sealing scrobicular ring and the sealing ring of establishing within it.
Described back-moving spring is made of with one heart different two helical springs different with elastic force of diameter.
The bigger spring diameter of described elastic force is greater than the less spring diameter of elastic force.
Expansion link of the present utility model need shift by the draining hole between the upper piston two ends at damping oil in telescopic process, has played the effect of damping, has delayed the reset speed of expansion link especially greatly.The dual reset spring utilizes the reasonable combination of the performance of the different elastic restoring force of two springs, when expansion link reduces at the restoring force of the final stage that resets owing to spring, pretend the power that is used on the piston rod also reduces thereupon, body of rod speed is slowed down, guaranteed that door has very slow speed when being about to close, realize the quiet work of the hinge and the process of closing the door.

The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises housing 1, expansion link 2, upper piston 3, lower piston 4 and big or small back-moving spring 5 and 6, the right-hand member of expansion link 2 slides and stretches into the openend (left end) of housing 1, is provided with black box 7 between the inside of expansion link 2 and housing 1 openend.Right-hand member at expansion link 2 is connected with upper piston 3, is provided with draining hole 8 between the two ends of this upper piston 3.Big back-moving spring 5 and diameter and the less little back-moving spring 6 coaxial right-hand members that are arranged in the housing 1 of elastic force that diameter and elastic force are bigger, the left end of described back-moving spring is provided with lower piston 4, and the two ends of back-moving spring are by the spring base positioning and fixing of right-hand member projection that is located at lower piston 4 and back-moving spring right-hand member.Between described upper piston 3 and lower piston 4, be filled with damping oil.
Side face at described upper piston 3 and lower piston 4 is provided with sealing scrobicular ring and the sealing ring of establishing within it 9.Be equipped with installing hole at the left end of expansion link 2 and the right-hand member of housing.
Referring to Fig. 3 and Fig. 4, the utility model is when being assembled into hinge, the installing hole of housing 1 right-hand member is hinged on the right part of loam cake 11 by pin 10, the installing hole of expansion link of the present utility model 2 outer ends is hinged by the right-hand member of a pin 18 and a flexure strip 12, the hinged inside of the other end of this flexure strip 12 and hinge side cover 13 1 ends, the fulcrum O of flexure strip 12 is by the left end lower hinge of pin 14 with loam cake 11.
Operating principle of the present utility model is:
When external force P acted on expansion link 2 (referring to Fig. 1), the body of rod 2 moved (shown in Figure 2) along the P direction, and damping oil process draining hole 8 flows into the left side of upper pistons 3, because:
H
2=S
1/ π R
2, H
3=S
2/ (π R
2-π R
1 2), wherein: S
1The volume of oil during for inactive state; S
2Volume when the body of rod 2 moves to H2=0 under the pressure P effect; H
2Be expansion link 2 distance between two pistons when not being subjected to external force, H
3It is the distance that upper piston 3 moves; R
1It is the radius of expansion link 2; R is the internal diameter of shell 1.When H3＞H2, this moment, back-moving spring was compressed energy storage.
When external force P=0, back-moving spring promotes expansion link 2 to left movement.Because the active area of S1 is bigger than the active area of S2, therefore it is little to act on the pressure that the pressure ratio on the S1 acts on the S2, this moment damping oil (left side of upper piston 3) slowly flow back into the right side of upper piston 3 through draining hole 8 from the S2 higher-pressure region, expansion link 2 resets (as shown in Figure 1), has played cushioning effect.
Fig. 3 is that spring-oil damping hinge core is installed in the structure chart in the hinge.Shell hinge 1 this moment of the present utility model is in closed condition, the state of spring-oil damping hinge core is as shown in Figure 1: when executing an external force P at hinge, power passes to flexure strip spare 12 from hinge side cover 13, flexure strip spare 12 is produced along the power of fulcrum O rotation, because part 12 is connected with hinge core 1, the expansion link 2 of hinge core 1 is compressed, and this moment, hinge was opened, as shown in Figure 4.The duty of hinge core 1 as shown in Figure 2 at this moment.At this moment, spring one oil damping hinge core 1 is in the energy storage state.
As shown in Figure 4, when executing an external force P in side cover 13, the rotation of hinge core 1 impeller 12 makes side cover spare 13 slowly reset (as shown in Figure 3).
