Description

Shock absorber adjustment device

This creation is related to shock absorbers, especially one that can adjust the structure of the shock absorber.

According to the locomotive, the locomotive has become one of the important means of transportation in life. The general locomotive will install shock absorbers on the front and rear wheels, which are mainly used to buffer the vibration of the vehicle due to uneven road surface or braking. The situation of discomfort such as sinking, so that the locomotive rider is more comfortable and safe on the ride.

However, most of the shock absorbers installed in original vehicles cannot change their shock-absorbing strength, so it is impossible to achieve the most appropriate shock-absorbing effect in response to different road conditions. Therefore, some knights will be more comfortable in order to achieve riding comfort. The adjustable shock absorber mainly adjusts the relaxation and compression of the spring in the shock absorber by an adjusting device to achieve a better cushioning effect. However, when the aforementioned shock absorber is to be adjusted, it needs to be adjusted by a special hand tool, so there is still inconvenience in use.

The main purpose of this creation is to provide a convenient operation Change the structure of the shock absorber strength.

Therefore, in order to achieve the above object, the present invention provides an adjustment device for a shock absorber, which mainly includes: a body having a constant hole in the axial direction, and a guiding groove at the bottom of the body is connected to the through hole, At least one limiting slot is disposed in the axial direction of the slot wall of the guiding slot; an adjusting button includes a head and an actuating rod disposed at a bottom end of the head, the actuating rod is disposed through the through hole of the body, and The outer edge of the actuating rod is provided with an external thread; and a pushing plate is disposed at the bottom of the body, and the pushing plate has a sleeve disposed on the guiding groove of the body, and the outer edge of the sleeve corresponds to the limiting groove There is a limiting portion, and the sleeve is axially provided with a screw hole screwed to the actuating rod.

When the adjusting button is rotated, the operating rod can be rotated, and the pushing plate is tilted to adjust the distance of the external thread of the operating rod, so that the pushing plate moves up and down along the limiting slot. The upper tube is moved up and down with respect to the outer tube of the shock absorber, thereby compressing or elongating the spring in the shock absorber to achieve the effect of adjusting the strength of the shock absorber.

Referring to FIG. 1 to FIG. 5, a preferred embodiment of the adjusting device (1) for a shock absorber is mainly composed of: a body (2), an adjusting button (3) and a push-up a disc (4), the adjusting button (3) is disposed inside the body (2), the pushing disc (4) is disposed inside the body (2) and on an opposite side of the adjusting button (3), And screwed into the adjustment button (3); wherein:

The main body (2) is provided with a constant hole (21) in the axial direction, and a receiving groove (22) is connected to the through hole (21) at the top of the main body (2), and the bottom of the receiving groove (22) The wall is provided with two corresponding positioning slots (23). In this embodiment, the two positioning slots (23) are opposite in a symmetrical position, but are not used to limit the structure and number thereof, and the number of positioning slots (23) is the least. The bottom of the body (2) is provided with a guiding groove (24) communicating with the through hole (21), and at least one limiting groove (25) is disposed in the axial direction of the groove wall of the guiding groove (24), in this embodiment The plurality of limiting slots (25) are provided, and the limiting slots (25) are semi-circular and spaced apart, but are not used to limit the appearance thereof; further, the receiving slots of the body (2) (22) There is a polygonal convex ring (26) around which the hand is urged by the operator; and the outer edge of the convex ring (26) is externally threaded on the outer edge of the body (2) ( S1), the external thread (S1) is screwed to an outer tube (5), as shown in FIG.

The adjusting button (3) comprises a head (31) and an actuating rod (32) disposed at a bottom end of the head (31). In the embodiment, the operating rod (32) is composed of the head (31) extends integrally, but is not intended to limit its structure. The head (31) is disposed in the accommodating groove (22), and the accommodating groove (22) is partially exposed, and the exposed top end is provided with a polygonal convex portion (33), the convex portion (33) The main purpose is to facilitate the operator's hand to apply force; the bottom end of the head (31) of the adjusting button (3) is provided with a bead groove (34) corresponding to each of the positioning grooves (23), and each of the bead grooves (34) is accommodated. An elastic member (35) is disposed between the elastic member (35) and the positioning groove (23). Furthermore, the actuating rod (32) is disposed through the through hole (21) of the body (2) and partially penetrates the guiding groove (24), and the actuating rod (32) of the guiding groove (24) The outer edge is provided with an external thread (S2), and the adjusting button (3) is axially provided with a through hole (37) extending through the head portion (31) and the actuating rod (32), and the hole wall of the through hole (37) is provided Having an internal thread (S3), the perforation (37) can be screwed by an adjusting bolt (S4), thereby rotating the adjusting bolt (S4) to adjust the damping oil flow inside the shock absorber, since it is not the scope of the present application, Therefore, the detailed structure will not be described again.
