Abstract
A reinforcement guide sleeve relates to improvement of a guide sleeve structure for orientation and positioning used in a front shock absorber of farm tricycle. The guide sleeve for orientation and positioning used in the existing front shock absorber of farm tricycle has the shortcoming of short sleeve body, low sleeve crown and straight port-shaped upper terminal of the sleeve crown, which affect the accuracy and stability of orientation of the guiding sleeve and making leakage of an oil seal on the upper terminal of the guiding sleeve easier. The utility model consists of a long sleeve body (1) and a high sleeve crown (2); the long sleeve body (1) and the high sleeve crown (2) are integrated, the long sleeve body (1) is arranged on the lower part, the high sleeve crown (2) is arranged on the upper part, the inner diameter of the long sleeve body is equal to that of the high sleeve crown (2), and the upper terminal of the internal wall of the high sleeve crown (2) is provided with a cone-shaped port. The cone-shaped port has a big top and a small lower part. Compared with the guiding sleeve of the front shock absorber of the original farm tricycle, the utility model lengthens the sleeve body, raises the sleeve crown, and arranges the cone-shaped port on the upper terminal of inner diameter of the high sleeve crown. The utility model has the advantages of increasing mechanical strength of the shock absorber, improving accuracy and stability of orientation of the guiding sleeve, while improving traffic safety factor.
Description
Technical field: the utility model relates to the improvement of leading in the preceding shock absorber of agricultural tricycle and locating usefulness guide pin bushing structure.
Background technology: the guide pin bushing that plays guiding and positioning action before the existing agricultural tricycle in the shock absorber exists that the cover body is short, hose-in-hose is short, the hose-in-hose upper end is the straight degree of lip-rounding, has influenced the accuracy rate and the steadiness of guide pin bushing guiding, also easily makes the oil sealing leakage of oil on the guide pin bushing.
The utility model content: the purpose of this utility model is a kind of reinforcing guide pin bushing of development, and it should have the mechanical strength that increases shock absorber, improves the accuracy rate and the steadiness of guiding, improves the safety factor of driving, and can help to overcome the characteristics of oil sealing leakage of oil.The utility model is made up of long cover body 1, high hose-in-hose 2; Long cover body 1 is connected as a single entity with high hose-in-hose 2, long cover body 1 is arranged on bottom, high hose-in-hose 2 is arranged on the top, the internal diameter of long cover body 1 equates with the internal diameter of high hose-in-hose 2, the upper end of high hose-in-hose 2 inwalls is provided with up big and down small conical orifice 3, the external diameter of long cover body 1 is less than the external diameter of high hose-in-hose 2, and the length of high hose-in-hose 2 is less than the length of long cover body 1.The guide pin bushing of shock absorber is compared before the utility model and the original agricultural tricycle, extended the cover body, increased hose-in-hose, internal diameter upper end at high hose-in-hose has conical orifice, make it have the mechanical strength that has increased shock absorber, improve the accuracy rate and the steadiness of guide pin bushing guiding, also improved the advantage of the safety factor of driving simultaneously.The conical orifice 3 of high hose-in-hose 2 inwalls upper end cooperates corresponding oil sealing can overcome the phenomenon of original oil sealing leakage of oil.
Description of drawings: Fig. 1 is an integral structure scheme drawing of the present utility model, and Fig. 2 is the structural representation of existing guide pin bushing.
The specific embodiment: present embodiment is made up of long cover body 1, high hose-in-hose 2; Long cover body 1 is connected as a single entity with high hose-in-hose 2, long cover body 1 is arranged on bottom, high hose-in-hose 2 is arranged on the top, long cover body 1 and high hose-in-hose 2 have more than the length of the cover body of existing guide pin bushing and hose-in-hose respectively and are no less than 40%, the internal diameter of long cover body 1 equates that with the internal diameter of high hose-in-hose 2 upper end of high hose-in-hose 2 inwalls is provided with up big and down small conical orifice 3, and the external diameter of long cover body 1 is less than the external diameter of high hose-in-hose 2, the length of high hose-in-hose 2 is less than the length of long cover body 1, and long cover body 1 outer wall inferior horn is a circular arc 4.
