Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-5 is please referred to, the utility model provides a kind of technical solution: a kind of damper upper end housing that stability is high, Including damper shell 1, piston rod 2, the first link block 3, rubber block 4, connection inner sleeve 5, the second link block 6, fixed block 7, connect Outer cover 8, spring 9, groove 10, connecting rod 11 and sliding block 12 are connect, the inside of damper shell 1 is connected with piston rod 2, and piston rod 2 top is equipped with the first link block 3, and rubber block 4 is located at the outside of piston rod 2, and the outside of rubber block 4 is connected in connection Set 5, the outside of connection inner sleeve 5 is provided with the second link block 6, and the second link block 6 is connected by fixed block 7 with outer cover 8 is connect It connects, the second link block 6 constitutes detaching structure, and the thickness of 26 upsides of the second link block, 2 rubbers on connection outer cover 8 The sum of the thickness of blob of viscose 4,2 thickness for connecting inner sleeve 5 and diameter dimension of piston rod 2 are equal on connection outer cover 8 The internal diameter of side, when connection outer cover 8, the second link block 6, rubber block 4 and connection 5 upper surface of inner sleeve are in the same horizontal position When, it can closely be connect with piston rod 2, so that connection outer cover 8 is fixed on piston rod 2, fixed block 7 is in the second link block 6 Upper spaced set, and the lower section of the second link block 6 is inclined to set, makes to fix stronger, makes the second link block 6 to moving down Internal diameter is gradually reduced when dynamic, fixed block 7 runs through the second link block 6, and fixed block 7 uses the side being threadedly coupled with outer cover 8 is connect Formula is connected, it may be convenient to the second link block 6 be connected with outer cover 8 is connect, spring 9 is located at the upper table of damper shell 1 Face, and the upside of spring 9 is connected with connection outer cover 8, the inside of connection outer cover 8 reserves fluted 10, and groove 10 passes through connection Bar 11 is connected with sliding block 12.

Such as the surface concave-convex surface structure of Fig. 3 and Fig. 4 rubber block 4, and rubber block 4 with connect inner sleeve 5 using pasting connection Mode be connected, and rubber block 4 is in " C " font with the cross-sectional shape for connecting inner sleeve 5, is made by the second link block 6 , to closely connect with piston rod 2, and the surface concave-convex surface structure of rubber block 4, rubber can be increased when extruding with reduced inner diameter Frictional force between blob of viscose 4 and piston rod 2 makes to fix stronger；

It is sliding if Fig. 5 sliding block 12 constitutes rotational structure, and the spaced set in groove 10 of connecting rod 11 in connecting rod 11 Block 12 reduces frictional force when connection outer cover 8 moves up and down between connection outer cover 8 and damper shell 1 by rotation, makes to connect Outer cover 8 does not influence the damping effect of damper when mobile, and increases the durability of the device.

Working principle: when using the stability high damper upper end housing, 8 sets of outer cover will be connected first in damper 1 outside of shell, then welds spring 9 with outer cover 8 is connect, then by 5 sets of inner sleeve of rubber block 4 and connection on piston rod 2, then The upper surface of rubber block 4 and connection outer cover 8 is maintained at the same horizontal plane, then the second link block 6 is inserted into connection 5 He of inner sleeve It connects between outer cover 8, then presses the second link block 6 downwards, since the lower section of the second link block 6 is oblique, second connects Block 6, rubber block 4 and connection inner sleeve 5 are connect in " C " font, there are certain notches, will when the second link block 6 moves down Second link block 6, rubber block 4 and connection inner sleeve 5 squeeze, and reduce opening, when the upper end of the second link block 6 is moved to and connects When 8 top of outer cover is parallel, opening disappears, and connection outer cover 8, the second link block 6, connection inner sleeve 5 and rubber block 4 are closely connected, Then fixed block 7 is inserted into from the top of the second link block 6, after the second link block 6 with connect the threaded connection of outer cover 8, both Connection outer cover 8 is fixed on piston rod 2, so that installation process is completed, and the surface of the first link block 3 is in thread-like structure, The objects such as the device and vehicle frame are facilitated to be connected, when this apparatus is used, zone of action piston bar of first link block 3 by power 2 move up and down on damper shell 1, and piston rod 2 drives connection outer cover 8 to move up and down, and connect and are provided with cunning on outer cover 8 Block 12, sliding block 12 is being rotated in groove 10 by connecting rod 11, and sliding block 12 is in contact with damper shell 1, in this way can be with Prevent connection outer cover 8 from the displacement of horizontal direction occurs, increase the stability of the device, and reduce connection outer cover 8 it is mobile when with subtract The frictional force that device shell 1 generates is shaken, does not influence the damping effect when device uses, and connects outer cover 8 and passes through spring 9 and subtract Shake device shell 1 is connected, and has both increased the damping effect of the device, and avoids connecting outside outer cover 8 and damper in compression process Shell 1 is in contact, and increases the durability and stability of the device, here it is the high damper upper end housing of stability use it is entire Process.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
