Abstract
The utility model discloses an omnidirectional jack, belonging to the technical field of the application technique of the hydraulic lifting tool. The purpose of the utility model is to make the jack have the effect of omnidirectional use without additionally providing auxiliary equipment. A vent hole is arranged on the outer wall of the oil tank, a partitioning device is arranged in the oil tank which is used for partitioning the oil and the air in the oil tank, the partitioning device is arranged between the vent hole and the oil in the oil tank, a diaphragm, a piston, or a telescopic soft pocket can be used as the partitioning device, and the partitioning device is made of rubber, plastic, or oilproof soft materials. The structure is good for the omnidirectional use of the jack, having the advantages of simple structure and simple manufacturing.
Description
The utility model belongs to Hydraulic for lifting load tool applications technical field.
Its structure of existing jack is: use oil pump piston 8 with the extraction of the fluid in the fuel tank 2, under the effect of check valve 6,4, the oil pressure of extracting out is gone into oil cylinder 3 forces piston 1 rising in it to reach the lifting purpose, after finishing using, open fuel-return valve 5 and make in-oil cylinder fluid backflow fuel tank 2, finish the lifting recuperation.The structural requirement jack of this jack can only be uprightly or is tilted to be no more than under the situation of miter angle and could use.For this reason, the designer who has separates the fuel tank hydraulic gear with piston rising mechanism, and with oil pipe two mechanisms is connected.Can only overcome above-mentioned shortcoming, but the jack of this separation uses trouble, and limited by tubing pressure, lifting weight only is 1/3 of traditional mechanism.Chinese patent 92204797.9 is introduced a kind of comprehensive jack, in existing jack structure, set up a fuel tank that can keep horizontal direction and when being inverted, produced the problem that the oil in the body fuel tank can not be extracted out by the oil pump tamponade, and reach the purpose of the comprehensive lifting of jack to augment jack.But this complex structure, use inconvenience must be carried additional fuel tank at any time and just can be used.
Therefore, the purpose of this utility model is: traditional jack is improved, and it is had does not increase auxiliary equipment, just can carry out the effect of comprehensive lifting, support.
The utility model realizes that the method for purpose is: air extractor vent 11 handlebar fuel tank inner fluid and air partitioning device spaced apart from each other in fuel tank are arranged on the fuel tank outer wall, this partitioning device is in fuel tank between air extractor vent 11 and the fuel tank inner fluid, partitioning device is a barrier film, barrier film one end is positioned at fuel tank 2 inside and outside wall tops, the other end is positioned at oil cylinder outer wall bottom, partitioning device also can be the lower end that piston, piston 12 are positioned at fuel tank air extractor vent 11, and the piston lower end is a fluid, and piston is ring-like piston.Partitioning device also can be flexible soft capsule, and soft capsule is positioned at fuel tank, and its bottom communicates with air extractor vent, and is fixed on the fuel tank upper end, and its top can be flexible to the fuel tank bottom.The piston of partitioning device, barrier film and flexible soft capsule are made by rubber or plastics or other grease proofing soft material.
Said structure has reached the purpose of this utility model, adopts this structure not need to add auxiliary equipment, can reach the effect of comprehensive use jack.The jack of conventional confguration is inverted when using, and air separates the oil in the fuel tank 2 with oil pump piston 8, and oil pump can not be extracted oil out the purpose of fuel tank out of reach lifting.No matter overcoming above-mentioned shortcoming, is inverted the partitioning device that the utility model adopts, still the partitioning device that tilts adopts and shrinks, extension or compacted form separate fluid and air, make the oil pump piston total energy extract the interior oil of fuel tank out, and reach the effect of comprehensive use jack.
Below in conjunction with Figure of description the utility model most preferred embodiment is described.
Fig. 1, be the scheme drawing of barrier film for the utility model partitioning device
Fig. 2, for practical partitioning device be the scheme drawing of piston
Fig. 3, be the scheme drawing of utility model partitioning device for flexible soft capsule
Fig. 4, be the partitioning device barrier film work scheme drawing of utility model
Embodiment 1: make piston 1, fuel tank 2, oil cylinder 3, check valve 4, fuel-return valve 5, check valve 6, oil pump oil cylinder 7, oil pump piston 8 and handle 9 as Fig. 1 and Fig. 4 with orthodox method, and install by orthodox method.
Establish air extractor vent 11 and communicate with fuel tank inner septum 10 one sides on fuel tank 2 outer walls, air extractor vent 11 optimal selections are on the fuel tank top, and an end of barrier film and fuel tank inside and outside wall the end sealing fixedly other end are positioned at oil cylinder outer wall bottom fixing seal.Barrier film is spaced from each other fluid and air extractor vent in fuel tank.
During use, press oil pump plug cock 8, extract the fluid in the fuel tank 2 out, fluid reduces air gradually and enters in the fuel tank by air extractor vent 11, under atmospheric effect, the barrier film of being made by rubber or plastics or other grease proofing soft material moves to the fuel tank outer wall gradually, thereby the fuel tank inner fluid is pressed to the fuel tank bottom.When so no matter jack is any angle, all can make in oil pump and each connection pipe to be full of fluid all the time, reach the effect of comprehensive support.After finishing using, open fuel-return valve 5, the oil backflow fuel tank in the oil cylinder 3 extrudes fuel tank with the air of the barrier film other end.
Embodiment 2(is as shown in Figure 2) in fuel tank, make piston 12 around oil cylinder 3, piston is ring-like piston, and its internal diameter is identical with the oil cylinder internal diameter, and its external diameter is identical with the fuel tank internal diameter.Piston is placed in the fuel tank, and its one side communicates with air extractor vent 11, and another side is positioned on the fuel tank fluid like this that piston 12 will ventilate and the fuel tank inner fluid separates.During use, air presses piston to move downwards, makes each pipeline of jack be full of fluid all the time, and time spent fluid backflow fuel tank rises piston air is extruded fuel tank.Piston is made with rubber, plastics or grease proofing soft material.
Embodiment 3(such as Fig. 3) air and fluid partitioning device are flexible soft capsule 13, soft capsule 13 is made by rubber or plastics or grease proofing soft material, make its bottom of wrinkle shape and communicate with air extractor vent, and fixing seal is on fuel tank.During use, when the fuel tank inner fluid moved downwards, air is oppressed soft capsule separated fluid of soft capsule and air, and its effect is identical with piston and barrier film.Soft capsule is made of rubber or plastics or grease proofing soft material.
The utility model also not only is confined to above-mentioned form, because the fundamental point of foregoing invention is with partitioning device fluid in the fuel tank and air to be separated, this separating except that above-mentioned described, also can adopt various ways.For example fuel tank is made of the soft material sealing of grease proofing leakproof, collapsible at the ambient pressure lower fuel tank, still can keep reaching above-mentioned effect, say the modification that still separates air assembly from this point for the utility model, still protected by the utility model claim.
