Abstract
The utility model relates to an entire weld manual hydraulic jack used for vehicle repair. A bottom base 1 is made from a steel plate with high quality density. The jack adopts the integral structure of entire weld type. The lower ends of an outer sleeve 2, an oil cylinder 4 and a pump body 8 are respectively welded in the corresponding grooves of the bottom base 1. The upper end of the outer sleeve 2 is together welded with the upper end of the oil cylinder 4. The utility model has the characteristics of no looseness, no deformation and no oil leakage. The service life of the jack is prolonged, the steel plate is sufficiently used and the cost is reduced.
Description
The utility model relates to a kind of full welded type hand-hydraulic jack, belongs to small-sized hand-operated lifting gear, is used for vehicle maintenance and repair.
The manual oil jack of QYL type of Chu Shouing in the market, produce by China's industry standard JB2104-91 regulation promulgated by the ministries or commissions of the Central Government, its base is to adopt the spheroidal graphite iron casting to form, by respective threads hole on the base respectively with oil cylinder, overcoat, the pump housing on be threaded; Oil cylinder and overcoat are also with being threaded.Though industry standard JB2104-91 promulgated by the ministries or commissions of the Central Government has respectively made regulation with the pump housing, base with being threaded of overcoat with overcoat, base with oil cylinder, oil cylinder to the base of this product, but under the lifting loading that is subjected to repeatedly, oil cylinder and overcoat, to produce elastic deformation repeatedly behind the pressurized between base and oil cylinder, overcoat, the pump housing and make in the threaded connection place and loosening, distortion to take place easily cause leakage of oil, thereby influence is with the service life of the jack that is threaded.Simultaneously, with the base of spheroidal graphite iron casting, foundry technique requires high, the cost height of product (6 yuan of per kilogram spheroidal graphite irons).
The full welded type hand-hydraulic of the utility model jack is not found in the prior art as yet.
The purpose of this utility model provides a kind of full welded type hand-hydraulic jack, and overcoat, oil cylinder, the pump housing are welded on respectively on the base that the high steel plate of matter density makes; Oil cylinder upper end and outer set upper side weld together make this jack become full welded type single piece.In use, not only prolonged service life, and reduced cost as bumping or unlikely loosening distortion and leakage of oil behind lifting pressurized repeated use.
For achieving the above object, the solution that the utility model adopts is: improving the manual oil jack of screw-type bonded assembly is the hand-hydraulic jack of full welded type single piece structure.Its base changes the high steel plate of matter density into by the spheroidal graphite iron cast molding and makes.The lower end of overcoat, oil cylinder, the pump housing is welded on respectively on the base in the corresponding grooves; Oil cylinder upper end and outer set upper side weld together make this jack become a full welded type single piece.Thereby solved the problem of easily loosening distortion and leakage of oil that is threaded, and prolonged the service life of jack.
The advantage of this full welded type hand-hydraulic jack is: (1) adopts full welded type single piece structure, cannot not have looseningly, indeformable, oil tight characteristics, has prolonged the service life of jack.(2) base made from the tailing of steel plate or steel plate is than the base matter density height of spheroidal graphite iron cast molding, the service life of having improved base; Make full use of steel, reduced cost (3 yuan of per kilogram steel plates).
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is the elevation cross-sectional view of the full welded type hand-hydraulic of the utility model jack.
As shown in Figure 1, the full welded type hand-hydraulic of the utility model jack is a single-stage, comprises base 1, overcoat 2, piston head 3, oil cylinder 4, piston rod 5, oil cylinder cover 6, pump core 7, the pump housing 8, battle pin 9, handle 10, adjusts screw rod 11.Base 1 adopts the high steel plate of matter density or the tailing of steel plate, and its periphery is made through fine limit work, makes full use of steel, cost-cutting (3 yuan of per kilogram steel plates).Corresponding a plurality of groove is arranged on the base 1.This jack adopts full welded type integral structure, and the lower end of overcoat 2, oil cylinder 4, the pump housing 8 is welded on respectively on the base 1 in the corresponding grooves; Overcoat 2 upper ends and oil cylinder 4 upper end weld togethers make that it cannot not have looseningly, indeformable, oil tight characteristics, have prolonged the service life of jack.The bearing pressure and can reach 1100Kg/cm of oil cylinder 4 and base 1 weld seam
2, stable and reliable for performance.Oil cylinder 4 has spacing hole, and hydraulic oil flows into from spacing hole and forms the store oil space between overcoat 2 and the oil cylinder 4; There is stepped hole oil cylinder 4 upper ends, and oil cylinder 4 is by the lower end of stepped hole and oil cylinder cover 6, and and piston rod 5 between put the O RunddichtringO, play sealing and dustproof effect.The below that piston head 3 is socketed in piston rod 5 is interference fit, and piston head 3 is equipped with the O RunddichtringO and seals.Piston rod 5 is put and is contained in the oil cylinder 4, and is reciprocating, and piston head 3 is the gap running-fit with oil cylinder 4, can slide up and down.Oil cylinder cover 6 is put the top that is contained in oil cylinder 4 and is socketed in and is the gap running-fit on the piston rod 5, and 6 pairs of piston rods 5 of oil cylinder cover are play the guiding role.On oil cylinder 4 and oil cylinder cover 6, the jump ring circle is housed all, to 4 restrictions of oil cylinder and positioning action; Oil cylinder cover 6 is played the effect of being convenient to keep in repair, and splitting out the jump ring circle can keep in repair.Adjustment screw rod 11 is put and is contained in the piston rod 5, works to adjust the lifting height.Handle 10 is put the top that is contained in pump core 7 by battle pin 9.Pump core 7 is arranged on and is the gap running-fit in the circular hole of the pump housing 8 and moves up and down, and pump core 7 has circular trough, is convenient to put seal ring.At the rear of handle 10 connecting rod is housed, the lower end of connecting rod is connected on the base 1, makes pump core 7 self-locking in the pump housing 8 upper ends, does not deviate from.
The principle of work of the full welded type hand-hydraulic of the utility model jack: pressing handle 10, pump core 7 is made upper and lower crank motion in the pump housing 8, in the pump housing 8, forming vacuum under the effect of O RunddichtringO, the hydraulic oil that is stored between overcoat 2 and the oil cylinder 4 is extracted in the pump housing 8 by the oil hole on the base 1, again hydraulic oil is pressed in the oil cylinder 4 by the oil hole on the base 1 through pump core 7 pressing handles 10, thereby piston rod 5 is risen, do lifting lifting campaign.As lifting lift height deficiency, adjust compensation by adjusting screw rod 11.
