[0002] In the field of modern mechanical maintenance and assembly, small jacks are widely used as a common lifting tool for positioning and adjusting various precision equipment. However, during use, due to the lack of effective fixing and limiting measures, the jacks often slip or become unstable, which not only affects work efficiency, but may also cause equipment damage or safety accidents.

[0032] The following is combined with Figure 1-6 The present invention is described in further detail.

[0033] Embodiment 1

[0034] like Figure 1-Figure 6 As shown, in order to solve the existing problems, in this embodiment, the present invention discloses a small jack for fixing and limiting large and small pipes of an oil receiver, including a base 1, a jack component 2 is connected to the top of the base 1, a lifting plate 3 is connected to the top of the jack component 2, a pressing component 4 is connected to the top of the lifting plate 3, and a clamping component 5 is connected to the top of the lifting plate 3.

[0035] The jack component 2 includes a rotating base 201 connected to the top of the base 1, a rotating bracket 202 is connected to the top of the rotating base 201, the rotating bracket 202 is rotatably connected to a rotating connecting rod 203, and the end of the rotating connecting rod 203 away from the rotating bracket 202 is rotatably connected to a transmission connecting rod 204.

[0036] A locking bolt 205 is provided on the side of the rotation connection between the rotating connecting rod 203 and the transmission connecting rod 204, and the transmission connecting rod 204 is symmetrically arranged on both sides of the rotating connecting rod 203. A nut 206 is connected to the outer side of the transmission connecting rod 204, and the nut 206 is threadedly connected to the locking bolt 205. The end of the transmission connecting rod 204 away from the rotating connecting rod 203 is rotationally connected to the bottom of the lifting plate 3 through a rotating connection bracket; a threaded member 207 is rotationally connected to the side of the transmission connecting rod 204, and the threaded members 207 are symmetrically arranged on both sides of the rotating base 201, and the two threaded members 207 are threadedly connected with a bidirectional screw 208.

[0037] The pressing component 4 includes a support column 401 connected to the top of the lifting plate 3, the top of the support column 401 is connected to a top bracket, the top of the top bracket is connected to an electric telescopic rod 402, the side of the top bracket is rotatably connected to a rotating connector 403, and the end of the rotating connector 403 away from the top bracket is connected to a telescopic rod 404.

[0038] The specific working principle is: this device can effectively improve the stability of the lifting and limiting fixation of the large and small tubes of the oil receiver. Compared with the traditional jack, the top of this device has a limiting structure, which can prevent the large and small tubes of the oil receiver from rolling during the process of lifting the large and small tubes of the oil receiver, thereby improving the stability of the transportation of the device.

[0039] When the device is in use, the distance between the two threaded members 207 can be controlled by rotating the bidirectional screw 208, thereby realizing the rotation control of the transmission connecting rod 204. When the lifting plate 3 is lifted to a suitable height, rotating the locking bolt 205 can make the transmission connecting rods 204 on both sides clamp the middle rotating connecting rod 203, thereby realizing the locking effect at the current height.

[0040] At this time, the large and small tubes of the oil receiver are placed on the top of the spring base 408, and the elastically sliding arc-shaped abutment parts 409 can abut against the two sides of the large and small tubes of the oil receiver, so as to prevent the large and small tubes of the oil receiver from rolling accidentally. At this time, the electric telescopic rod 402 is started, driving the connecting part 406 to move downward, and the two rotating telescopic rods 404 are driven to extend and retract outward through the structure of the transmission part 407, and rotate at the same time, so that the arc-shaped pressing part 405 at the bottom of the telescopic rod 404 contacts and presses the arc surface at the top of the large and small tubes of the oil receiver.

[0041] At this time, the other end of the large and small tubes of the oil receiver extends into the fixed ring 502. At this time, the rotating ring 503 is rotated to guide the transmission column 506 through the arc groove 507 and the sliding groove 504 at the same time, so that as the rotating ring 503 rotates, the multiple groups of clamping parts 505 are moved closer to the center of the circle, thereby achieving the clamping effect of the large and small tubes of the oil receiver.

[0045] The clamping component 5 includes a clamping base 501 connected to the top of the lifting plate 3. The top of the clamping base 501 is connected to a fixed ring 502 through a connecting column. The side of the fixed ring 502 is rotatably connected to a rotating ring 503. The outer arc surface of the rotating ring 503 is provided with an anti-slip groove.

[0046] The rotating ring 503 is provided with a penetrating sliding groove 504, and a transmission column 506 is slidably connected to the inner wall of the sliding groove 504. A clamping piece 505 is connected to one end of the transmission column 506, and the clamping piece 505 faces the center direction of the fixed ring 502. An arc groove 507 is provided on the side of the fixed ring 502 close to the rotating ring 503, and the transmission column 506 is slidably connected to the inner wall of the arc groove 507.

[0047] The specific working principle is: through the combination of the rotating ring 503 and the fixed ring 502 of the device, the synchronous sliding effect of several clamping parts 505 can be achieved, thereby achieving uniform clamping of the tubular structure, preventing the raw materials from accidentally sliding during the use of the device, and at the same time, through the circumferentially distributed clamping part 505 structure, the device can achieve compatibility with oil receiver pipes of different diameters within a certain range with a stable clamping effect.
