New description: [New technical field] This creation is about a shock absorber with enhanced shock absorption structure, especially a shock absorber installed on the front wheel of the locomotive and the front frame as shock absorber. [Prior Art] Please refer to the seventh figure. A shock absorber (90) is used as a common shock absorber at the bottom end of the locomotive. It is used to absorb the front wheel and touch the ground during locomotive driving. And the vibration generated. The prior art shock absorber tube (90) conceptually includes an outer tube and an inner tube (92), wherein the lower end of the outer tube (91) is fixedly coupled to the front wheel, and one end of the inner tube (92) is relatively slipperable The ground is disposed in the outer tube (91), and the other end is fixed on the shoulder of the uranium fork, and is provided with elastic elements between the two movable inner and outer tubes (g) (g2) (for example: spring ), so that the inner and outer tubes (g 1 ) ( g 2 ) can be buffered and absorbed by the expansion and contraction of the elastic element during the shock-slip relative movement, and the inner and outer tubes (91) (92) Further, the oil is further injected, thereby increasing the resistance between the inner and outer tubes (91) (92) relative movement to enhance the shock absorbing capability, however, the resistance provided by the oil pressure is shocked by the shock absorber (g 〇) At this time, the reaction time of the inner and outer tubes (91) (92) to be relatively moved at the moment of shock is prolonged, which affects the immediacy of the shock absorbing action. Such a design is insufficient for the comfort of the locomotive driving. Where. [New content] In view of the above-mentioned shortcomings of the prior art, the present invention designs a shock absorber with an enhanced shock absorbing structure, which has an improved structure to increase the reaction speed of the shock absorbing action. M342325 In order to achieve the above objectives, the technical means adopted in this creation is to set up a shock absorber tube with a reinforced shock absorbing structure, which comprises an external officer with a top opening at the top and a push-inner tube at the outer ring. The end portion is slidably disposed in the opening of the outer tube, and a positioning portion is disposed on the outer ring wall surface at the end; the pushing member is sleeved on the positioning portion of the inner tube, and a perforation is formed through the end portion And the outer ring wall surface is outwardly protruded and formed into a convex ring wall; between the parts: the elastic element is pushed against the convex ring wall of the pushing member and the outer tube is pushed. When the creation is used, the inner tube can be used. Fixed on the shoulder of the front frame, = outside! * Correspondingly connected to the front wheel, and the shock absorber is subjected to vibration and then the inner tube is relatively moved in the outer tube for telescopic shock absorption, because the component can -Additional auxiliary shock absorption effect, so you can increase the avoidance and shock effect. In addition, the elastic force of the elastic element can be used to shorten the reaction time of the inner and the opposite movements, so that the shock absorber is better. The purpose of the reverse is to have a gain for the suspension trip. [Embodiment]: As shown in the first and second figures, the shock absorber of the reinforced shock absorbing structure of the present invention includes an outer tube (1 〇), an inner tube (2), a pusher (3 〇), and An elastic element (40). The outer tube (10) is hollow inside and has an opening at the top end thereof. (11) The outer portion of the tube (11) can be filled with oil, and the outer ring of the outer tube (11) is flared to form a pushing portion (12). M342325 The inner tube (20) is slidably disposed in the opening (11) of the outer tube (10) at one end thereof, and a positioning portion (21) is disposed on the outer wall surface at the other end thereof. Further referring to the third and fourth figures, in the first embodiment, the positioning portion (21) may include a threaded section (211), and a bulge is formed at the wall surface of the threaded section (211). The limiting ring is convex (212), and in the second embodiment, the positioning portion (21) may include a concavely formed annular groove (213). The pushing member (30) is sleeved and fixed on the positioning portion (21) of the inner tube (20). The ringing member (30) is a ring-shaped sleeve, and a through hole (31) is formed on the outer wall of the inner tube (2〇). And the outer ring wall surface is outwardly protruded and formed into a convex ring wall (32), and in the first embodiment, the through hole (31) may further be provided with a thread to be correspondingly and screwed to the fixed portion. (21) The threaded section (21丨), the top end of which can be used to limit displacement by pushing up to the limit ring protrusion (212); in the second embodiment, the pushing member (3〇) The top wall corresponds to the annular groove (213) of the fixing portion (21), and a limiting collar (33) (for example, a C-ring) is sleeved on the annular groove (213) to limit the pushing member (3〇). ) Moved up. The aforementioned elastic member (40) may be a spring that is pushed between the convex ring wall (32) of the pushing member (3〇) and the pushing portion (12) of the outer tube (1〇). Please refer to the fifth and sixth figures. In this application, the inner tube (20) can be fixed to the shoulder seat (71) of the front fork frame (70), and the outer tube (1叼 correspondingly fixed and fixed) When the front wheel is vibrated and the inner tube (2〇) is relatively moved in the outer tube (10) for telescopic shock absorption, the elastic element (40) can provide an additional auxiliary shock absorbing effect. In addition to the shock absorption effect of the shock absorber, the design of the M342325 elastic element (40) can be used to move relative to the inner and outer tubes (20) (10). The reaction time can be reached for the movement, and for the shock absorbers, the 士士#, ,, 3 has "good points"; in the first embodiment: the user can adjust the pusher by screwing (10) The position of the adjustment bomb 1 ± 70 pieces (40) of the degree of tightness 'to make the shock absorber more flexible in use to correspond to different road conditions.
