Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic jacks, in particular to a separation type hydraulic jack. Background Art

[0002] The hydraulic jack is a hydraulic pump driven by manpower or electricity, which is transmitted through a hydraulic system and uses a cylinder or piston as a lifting piece. The separate hydraulic jack is separated from the hydraulic pump and connected in the middle with a high-pressure hose. It consists of a cylinder and a piston rod. The cylinder is provided with an oil hole. The bottom end of the cylinder is supported on the ground, and a piston head is installed on the upper end of the piston rod. When the hydraulic pump supplies oil to the cylinder, the piston rod moves outward along the direction of the cylinder. After the piston head lifts the equipment to be lifted to a predetermined height, it is locked with the help of a hydraulic lock in the oil circuit to ensure the lifting height of the equipment. The hydraulic jack has a compact structure, can lift heavy objects steadily, works steadily, has a self-locking effect, and has a high transmission efficiency, so it is widely used.

[0003] The hydraulic oil pump of a traditional split hydraulic jack is usually arranged on a frame, and a pressure gauge is usually arranged on the frame to detect the pressure. However, the hydraulic oil pump and the pressure gauge are always exposed outside the frame. They may be damaged by unexpected situations such as vibration, bumps or collisions during transportation or storage, thereby affecting the normal use of the split hydraulic jack and increasing the maintenance cost of the equipment. Therefore, a split hydraulic jack is proposed to address the above situation. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 A separate hydraulic jack includes a frame 1 and a hydraulic cylinder 104. A pair of handles are provided on the top of the frame 1. A hydraulic oil pump 101 and a pressure gauge 102 are provided on the top of the frame 1. A high-pressure oil pipe 103 is fixedly connected to the hydraulic oil pump 101. One end of the high-pressure oil pipe 103 away from the hydraulic oil pump 101 is fixedly connected to the hydraulic cylinder 104.

[0025] The frame 1 is provided with positioning holes 105 and receiving slots 106 , and the frame 1 is slidably fitted with a protective frame 2 .

[0026] The design of the storage slot 106 can realize the storage and placement of the cover plate 4 when the device is used, thereby reducing the space occupied by the cover plate 4.

[0027] The protective frame 2 has a cavity 201, and the top and bottom of the protective frame 2 both have openings. The front and rear ends of the protective frame 2 are each provided with a pair of screw holes 202 connected to the cavity 201. The internal threads of the screw holes 202 are matched with hand screws 3, and the protruding ends of the hand screws 3 are matched with the positioning holes 105.

[0028] In order to prevent the protective frame 2 from interfering with the installation of the high-pressure oil pipe 103 when the device is in use, Figure 1 , Figure 2 and Figure 3 As shown, a groove body connected to the cavity 201 is opened at the left end of the protection frame 2, and the groove body cooperates with the high-pressure oil pipe 103.

[0029] The top of the protection frame 2 is clamped with a cover plate 4. In order to limit the position of the installed cover plate 4, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, four slots 203 are provided on the top of the protection frame 2 , and four protrusions 401 are provided on the top of the cover plate 4 , and the protrusions 401 cooperate with the slots 203 .

[0030] During carrying and transportation, Figure 1As shown, the protective frame 2 can be raised, and then the hand screw 3 can be screwed into the screw hole 202 so that the hand screw 3 extends into the positioning hole 105. Then the cover plate 4 can be pulled out from the storage groove 106 and covered on the top of the protective frame 2, thereby effectively preventing the hydraulic oil pump 101 and the pressure gauge 102 from being bumped or hit by the external environment, reducing the risk of damage or failure of these key components. At the same time, the hydraulic oil pump 101 and the pressure gauge 102 are effectively protected during transportation, thereby reducing the risk of safety accidents caused by equipment damage and improving safety of use.

[0031] The surface of the protection frame 2 is provided with two sets of snap-fit ​​structures, which include long convex strips 501 provided at the front and rear ends of the protection frame 2 and two pairs of short convex strips 5 at the left and right ends of the protection frame 2 .

[0032] like Figure 3 As shown, the short convex strips 5 and the long convex strips 501 are both made of rubber material, and the distance between two adjacent short convex strips 5 is the same as the distance between two adjacent long convex strips 501 .

[0033] When in use, the high-pressure oil pipe 103 is wound around two adjacent short ridges 5, and along the surface of the protective frame 2, the high-pressure oil pipe 103 is wound around and clamped on the adjacent long ridges 501 and short ridges 5 in turn, thereby further facilitating transportation and carrying.
