Description
Technical Field
The utility model relates to a gate hinge of five metals trade, concretely relates to regulation needle structure of hydraulic pressure type door closing hinge.
Background
The hydraulic hinge is a full-name torsion spring type hydraulic buffering door closing hinge, and is one of several hinges with door closer functions commonly seen in the market at present; is one of the automatic door-closing hinges that was first found on the market to replace door closers.
Hydraulic hinge theory of operation: when the hinge is opened, the cam in the hinge moves axially, and the torsion spring arranged in the shaft is distorted and deformed to generate a reaction closing force; a small oil cylinder is arranged in the middle shaft of the hinge, and a cam with an oil return hole slides back and forth along the wall of the oil cylinder to generate retardation, namely hydraulic pressure is generated; when the hinge is closed, the pressure generated by torsion of the torsion spring forces hydraulic oil in the oil cylinder to flow through the small hole of the piston, and the oil flow speed is slow due to the small hole diameter of the oil hole, so that the torsion spring is prevented from closing the door quickly, and the buffer is generated.
The hinge is internally provided with an adjusting needle, namely the adjusting needle is inserted into the cam, the size of the residual gap of the oil return hole is controlled through the diameter of the adjusting needle in the oil return hole of the one-way valve, so that the flow of oil is controlled, the aim of controlling the hydraulic pressure is fulfilled, and the door closing speed and the door closing force are finally controlled.
The problem that current regulation needle exists is: with the refinement of the industry, the closing stroke of the door can be divided into different stages, such as a pre-pressing section, a door opening/closing section, a locking section and the like. For example, the door opening/closing section needs the door leaf to move at a constant speed, the pre-pressing section needs the door leaf to move at a reduced speed so as to allow people to pass through, the locking section needs to move at an increased speed so as to increase the closing speed of the door leaf, impact force is formed, and locking is completed. And the simple structure of traditional regulation needle and oil gallery cooperation department is mostly at the uniform velocity oily, especially when door leaf hasp section, appears the door leaf hasp dynamics easily and leads to the problem that the door did not close inadequately.
Disclosure of Invention
The utility model discloses a solve the not enough of above-mentioned technique, provide a regulation needle structure of hydraulic pressure type door closing hinge.
The technical scheme of the utility model: the utility model provides a regulation needle structure of hydraulic pressure type door closing hinge, the regulation needle includes the control shaft and crosses the oil axle, should cross the oil axle including inserting end and first link end, the control shaft is equipped with the external screw thread, it is the frustum type to cross the oil axle, should cross the diameter of inserting end of oil axle and be greater than first link end diameter, it is equipped with the draining groove to cross first link end one side of oil axle, and this draining groove diameter is less than first link end diameter.
By adopting the technical scheme, the control shaft of the adjusting needle is inserted into the central threaded hole of the hinge end cover, and the control shaft is matched with the central threaded hole through the external thread on the control shaft, so that a user can drive the oil shaft to relatively enter or exit the oil return hole of the one-way valve, namely, the insertion depth of the oil shaft is controlled.
Because the oil passing shaft is of a frustum structure, when the oil passing shaft is positioned at different depth positions relative to the oil return hole, the diameter of the oil passing shaft at the position opposite to the oil return hole is different, namely the oil passing gap between the oil return hole and the oil passing shaft is changed along with the change of the axial positions of the oil return hole and the oil passing shaft. The door closing speed becomes faster gradually as the gap becomes larger.
In addition, the oil drainage groove is formed in one side of the first connection end, when the oil return hole meets the oil drainage groove, the gap is suddenly enlarged, damping hydraulic pressure and spring resistance disappear, the spring releases full force, and the door closing speed and force are increased. And the relative position of the oil drainage groove and the oil return hole can be controlled through the adjustment of the screw threads, so that the section of the door leaf at which the door leaf starts to accelerate is set.
Therefore, the utility model discloses an adjust the needle structure because the setting in draining groove obtains better door effect of closing.
The utility model discloses a further setting: the control shaft and the first connection end of the oil passing shaft are arranged in a split mode, the control shaft comprises a torsion end and a second connection end, a ball hole is formed in the end face of the second connection end, a ball head matched with the ball hole is arranged on the first connection end, and the oil passing shaft is inserted into the ball hole of the control shaft through the ball head and movably connected.
Adopt above-mentioned technical scheme, traditional regulation needle is mostly integrative setting, and its defect lies in requiring the axiality extremely high, otherwise inserts the oil axle of crossing in the oil return hole, can be because of off-centre and fracture, causes the hinge trouble a lot of. And the utility model discloses a split type design, the oily axle of mistake is through the bulb and insert the downthehole swing joint that is of control axle bulb, has guaranteed promptly that the UNICOM of oily axle and control axle feeds, can avoid the oily axle fracture again.
The utility model discloses a further setting: and the control shaft is provided with a sealing ring and a mounting groove matched with the sealing ring in shape.
By adopting the technical scheme, the oil is prevented from leaking through the arranged sealing ring.
The utility model discloses a further setting: an inner hexagonal groove is formed in the end face of the torsion end of the control shaft.
By adopting the technical scheme, the user can feed through the tool rotating adjusting pin through the arranged inner hexagonal groove, and the cross groove, the square groove and other structures are the same.
