Abstract
The utility model discloses a damper used for a cylinder cover. The damper comprises a damping rod (1), a shell body (2), an internal piston rod (3) and an external piston rod (4), wherein the damping rod (1) is in screw joint with the shell body (2), the external piston rod (4) is connected with the shell body (2) in a sleeved mode, the internal piston rod (3) is connected with the inner side of an internal hole of the external piston rod (4) in a sleeved mode, one end of the internal piston rod (3) is provided with a groove for insertion of one end of the damping rod (1), one end, inserted into the groove of the internal piston rod (3), of the damping rod (1) is provided with a liquid channel (1.1) communicating the end face of the damping rod (1) and the side face of the damping rod (1), a section of damping holes (1.2) are formed inside the liquid channel (1.1) which is a straight hole channel, the liquid channel (1.1) uses straight holes, and therefore damping liquid can stably and smoothly pass through the liquid channel, namely mechanism motions are stable and smooth, and damping effects are good.
Description
Technical field
The utility model relates to the mechanical motion field, is a kind of damper that is used for cylinder head concretely.
Background technique
Damper, be so that the resistance of motion to be provided, the device of depletion kinergety, at present, the damper that is used for cylinder mainly comprises damper rod 1 ' as shown in Figure 1, housing, inner piston rod and outer piston cover, damper rod 1 ' is spirally connected with housing, outer piston cover and housing socket, inner piston rod is socketed in the endoporus of outer piston cover, inner piston rod one end is provided with and is used for the groove that damper rod 1 ' one end embeds, the end that damper rod 1 ' embeds the inner piston rod groove is provided with fluid passage 1.1 ', fluid passage 1.1 ' one end opening is positioned at the lower end surface of damper rod 1 ', fluid passage 1.1 ' the other end opening is positioned at the side of damper rod 1 ', is provided with one section damping hole 1.2 ' in the fluid passage 1.1 '.Form because this fluid passage 1.1 ' is communicated with by two sections straight holes, the axis of two sections straight holes is 90 ° of angles, so damp liquid is not steady, smooth and easy when fluid passage 1.1 ' circulation, this just causes inner piston rod bumpy motion, smooth and easy, and damping is bad.
The model utility content
The technical problems to be solved in the utility model is, a kind of mechanism kinematic steady and smooth, damper that is used for cylinder head that damping is good of making is provided.
For solving the problems of the technologies described above, a kind of damper that is used for cylinder head of the present utility model, comprise damper rod, housing, inner piston rod and outer piston cover, damper rod and housing are spirally connected, outer piston cover and housing socket, inner piston rod is socketed in the endoporus of outer piston cover, inner piston rod one end is provided with and is used for the groove that damper rod one end embeds, the end that damper rod embeds the inner piston rod groove is provided with the fluid passage that is used to be communicated with damper rod end face and side, be provided with one section damping hole in the fluid passage, described fluid passage is the straight hole passage.
As preferably, the angle of described fluid passage axis and damper rod axis is 30 ° ~ 60 °.
After adopting said structure, the utlity model has following advantage: fluid passage adopts straight hole, makes damp liquid more steady, smooth and easy by fluid passage the time, even mechanism kinematic steady and smooth more, damping is good.
As improvement, the end that described damper rod embeds the inner piston rod groove is provided with ball recess, and the fluid passage lower ending opening is positioned at ball recess.Adopting damper rod one end face is ball recess, makes that damp liquid is easier to converge, and damping is better.
