Description

Technical Field

[0001] The utility model relates to the technical field of adjusting feet, and particularly relates to a lifting adjusting foot. Background Art

[0002] An adjusting foot is a device for adjusting height, usually used for the bottom support of furniture, machinery and equipment, etc. As one of the common spare parts in mechanical equipment, the adjusting foot is mainly used to adjust the level, height and tilt angle of the machinery and equipment. It controls the height of the adjusting foot by rotating a nut, so that the machine can be stably supported. At the same time, the adjusting foot has a certain buffering and shock-absorbing effect, which can reduce the noise and vibration generated by the machine due to vibration.

[0003] During the process of adjusting the height of the machinery and equipment, by rotating the support foot, the distance between the support foot and the threaded sleeve is increased to achieve the purpose of adjusting the height of the machinery and equipment.

[0004] During the process of adjusting the height of the machinery and equipment, the traditional adjusting foot is not lubricated regularly, so it may cause rust on the external surface thread of the support foot, making the adjusting foot unable to rotate to adjust the height and reducing its service life.

[0017] (III) Beneficial effects

[0018] The present invention provides a lifting adjustment foot. It has the following beneficial effects:

[0019] 1. Through the extrusion assembly, by pressing the extrusion block to move downward, the connecting rod is driven to slide downward, pushing the extrusion plate to move downward, so that the extrusion plate pushes the support rod to move downward, thereby pushing the baffle plate to squeeze the sponge, causing the lubricating oil in the sponge to flow downward along the inclined surface of the support plate and flow out downward through the oil leakage hole, so that the lubricating oil flows downward along the thread on the inner surface of the threaded sleeve, lubricating the inner wall of the threaded sleeve and the outer surface of the support foot, thus facilitating screwing and increasing the service life of the adjustment foot.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Embodiment 1

[0030] Refer to Figure 1 、 Figure 2 And Figure 3, which is the first embodiment of the present utility model. This embodiment provides a lifting-adjustable foot, including a threaded sleeve 1, a support foot 2 is threadedly connected inside the threaded sleeve 1. A chute 201 is opened at the inner axis of the support foot 2, an extrusion assembly 3 is arranged in the chute 201, and a support assembly 4 is arranged on the inner surface of the threaded sleeve 1;

[0031] The extrusion assembly 3 includes an extrusion block 301 slidably connected in the chute 201. A connecting rod 302 is fixedly connected to the upper surface of the extrusion block 301. A groove 202 is opened on the upper surface of the support foot 2. One end of the connecting rod 302 extends into the groove 202 and is fixedly connected to an extrusion plate 304. A telescopic spring 303 is fixedly connected to the upper surface of the extrusion block 301. The other end of the telescopic spring 303 is fixedly connected to the inner surface of the chute 201, and the telescopic spring 303 is sleeved on the outer surface of the connecting rod 302.

[0032] Specifically, an oil injection port 101 inclined downward is opened on the outer surface of the threaded sleeve 1.

[0033] Furthermore, through the extrusion assembly 3, by pressing the extrusion block 301 to move downward, the connecting rod 302 is driven to slide downward, pushing the extrusion plate 304 to move downward, so that the extrusion plate 304 pushes the support rod 402 to move downward, thereby pushing the baffle 403 to squeeze the sponge 5, so that the lubricating oil in the sponge 5 flows downward along the inclined surface of the support plate 401 and flows out downward through the oil leakage hole 405, so that the lubricating oil flows downward along the thread on the inner surface of the threaded sleeve 1, lubricating the inner wall of the threaded sleeve 1 and the outer surface of the support foot 2, thus facilitating screwing and increasing the service life of the adjustable foot.

[0034] Embodiment 2

[0035] Referring to Figure 1 、 Figure 3 And Figure 4 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0036] The support assembly 4 includes a support plate 401 movably connected to the inner wall of the threaded sleeve 1. An oil leakage hole 405 is opened on the outer surface of the support plate 401 near the thread. A support rod 402 is slidably connected inside the support plate 401. One end of the support rod 402 is fixedly connected to a baffle 403. A support spring 404 is fixedly connected to the upper surface of the support plate 401, and the other end of the support spring 404 is fixedly connected to the lower surface of the baffle 403. A sponge 5 is fixedly connected to the inner top wall of the threaded sleeve 1. The support spring 404 is sleeved on the outer surface of the support rod 402;

[0037] Specifically, the other end of the support rod 402 extends to the outside of the support plate 401. A cross-shaped slot is provided at the bottom of the support plate 401. The sponge 5 is saturated with lubricating oil. The sponge 5 is in the shape of an inverted frustum. The support plate 401 is threadedly connected to the inner surface of the threaded sleeve 1, and the support plate 401 is in the shape of a frustum. A stud 102 is threadedly connected to the upper surface of the threaded sleeve 1. The stud 102 can be replaced with a square plate 6, and the square plate 6 is movably connected to the upper surface of the threaded sleeve 1.

[0038] Furthermore, through the support assembly 4, the baffle 403 can squeeze the sponge 5, causing the lubricating oil inside the sponge 5 to flow out, thereby lubricating the threaded connection between the threaded sleeve 1 and the support foot 2. By using the support spring 404, when the pressing plate 304 moves away from the support rod 402, the support spring 404 drives the baffle 403 away from the sponge 5, facilitating the next lubrication process, thus improving the practicality of the device, making it convenient to turn the support foot 2 and adjust the height of the adjusting foot.

[0039] Working principle: The staff first turns the support foot 2 so that the support foot 2 moves into the threaded sleeve 1. When the support foot 2 is turned to a certain distance, press the extrusion block 301 to move downward, thereby driving the connecting rod 302 to slide downward and pushing the pressing plate 304 to move downward. The pressing plate 304 then pushes the support rod 402 downward, thus pushing the baffle 403 to squeeze the sponge 5. The lubricating oil in the sponge 5 flows downward along the inclined surface of the support plate 401 and flows out downward through the oil leakage hole 405, causing the lubricating oil to flow downward along the thread on the inner surface of the threaded sleeve 1 to lubricate the inner wall of the threaded sleeve 1 and the outer surface of the support foot 2, making it convenient to turn. Release the extrusion block 301, and use the support spring 404 to drive the baffle 403 away from the sponge 5. Use the telescopic spring 303 to drive the connecting rod 302 to move outward, thereby driving the pressing plate 304 away from the support rod 402. Pour lubricating oil into the sponge 5 through the oil pouring port for the next lubrication process.
