Description

Technical Field

[0001] The utility model relates to the technical field of adjustable feet, in particular to an adjustable adjustable foot. Background Art

[0002] With the development of the times and the advancement of science and technology, more and more large-scale equipment appear in our lives. When we install these equipment, in order to ensure the smooth operation of the equipment, we need to adjust the equipment to a horizontal level. In uneven positions, auxiliary tools are needed to adjust the height so that the equipment can reach a level and maintain stable operation.

[0003] Adjustment feet. The existing adjustment feet are divided into two components, including bolts and foot pads. When the equipment needs to be grounded, threaded holes are pre-reserved at different positions on the lower surface of the equipment, and then the bolts are screwed into the threaded holes. The local height of the equipment is controlled by adjusting the distance at which the bolts are screwed in, thereby achieving the adjustment of the local height of the equipment. Through the joint cooperation of several adjustment feet, the equipment can finally be leveled.

[0004] The existing adjustment feet are only screwed into threaded holes by bolts, and then contact the ground through foot pads to support the equipment. The height that the entire adjustment foot can support depends entirely on the length reserved outside after the bolts are screwed into the threaded holes when the adjustment foot is installed. Whether the level can be adjusted can only depend on the experience of the workers during installation. The height cannot be adjusted after the equipment is placed, and the practicality is low.

[0030] Specifically, a plurality of adhesive strips 204 are fixedly connected to the upper surface of the internal threaded tube 201 , and a flexible strip 206 is fixedly connected to the lower surface of the external threaded tube 202 .

[0031] Furthermore, by rotating the outer cylinder 1, the internal threaded cylinder 201 is driven to rotate, and the internal threaded cylinder 201 drives the rectangular limit block 203 to rotate through the internal rectangular cavity, and the rectangular limit block 203 is embedded in the rectangular cavity, thereby driving the threaded rod 205 to rotate, so that the threaded rod 205 is fixedly connected to the threaded hole reserved for the equipment, and after the threaded rod 205 is screwed into the threaded hole, the upper surface of the internal threaded cylinder 201 is abutted against the outer surface of the equipment, and the adhesive strip 204 on the upper surface of the internal threaded cylinder 201 is bonded to the outer surface of the equipment, thereby assisting the fixation of the internal threaded cylinder 201 to the equipment, and then by rotating the external threaded cylinder 202, the threads on the outer surface of the external threaded cylinder 202 move on the threads on the inner wall of the internal threaded cylinder 201, so that the external threaded cylinder 202 moves downward, thereby realizing the height adjustment, and the lower surface of the external threaded cylinder 202 is fixedly connected with a soft strip 206, so that the external threaded cylinder 202 plays a buffering role when supporting.

[0032] Example 2

[0033] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment. The locking assembly 3 includes a connecting tube 302 fixedly connected to the bottom of the inner cavity of the externally threaded tube 202. The outer surface of the connecting tube 302 is hinged with an outer support rod 301. The outer surface of the outer support rod 301 is fixedly connected with a driving rod 309. The end of the driving rod 309 away from the outer support rod 301 is movably connected with a connecting column 305. The lower surface of the connecting column 305 is fixedly connected with a spring 306. The bottom end of the spring 306 is fixedly connected to the bottom end of the inner wall of the externally threaded tube 202.

[0034] Specifically, a jacking column 307 is fixedly connected to the bottom end of the connecting column 305. A connecting frustum 308 is fixedly connected to the bottom end of the jacking column 307. The outer surface of the frustum abuts against two connecting rods 304. Fixedly connected to one end of each of the two connecting rods 304 passing through the external thread cylinder 202 is a pressing block 303. At one end of each of the two connecting rods 304 close to the connecting frustum 308, an oblique angle corresponding to the connecting frustum is provided. There are three outer support rods 301 in total. Rectangular grooves corresponding to the three outer support rods 301 are provided on the outer surface of the connecting column 305. One end of the outer support rod 301 is hinged to the inner wall of the rectangular groove. A ring groove is provided on the outer surface of the connecting column 305. The outer surface of the driving rod 309 abuts against the inner wall of the ring groove.

[0035] Furthermore, the connecting column 305 is bounced by the spring 306, such that the driving rod 309 is affected by the ring groove on the outer surface of the connecting column 305, thereby driving the outer support rod 301 to rotate outwards. When it is necessary to retract the outer support rod 301, by pressing the pressing block 303, the two connecting rods 304 are driven to squeeze inwards. At one end of the connecting rod 304 close to the connecting frustum 308, an oblique angle the same as the inclined surface of the frustum is provided. When the two connecting rods 304 are squeezed inwards, the connecting frustum 308 is driven to move downwards, thereby pulling the connecting column 305 downwards through the jacking column 307. At this time, the connecting column 305 drives the outer support rod 301 to rotate inwards through the cooperation of the ring groove and the driving rod 309. Rectangular grooves corresponding to the outer support rod 301 are provided on the outer surface of the connecting cylinder 302. The distance that the connecting frustum 308 drives the connecting column 305 to move downwards through the jacking column 307 is sufficient to drive the outer support rod 301 to rotate inwards and return to the rectangular groove on the outer surface of the connecting cylinder 302. Moreover, the ring groove on the outer surface of the connecting column 305 has a certain width, sufficient for the driving rod 309 to move within the ring groove when rotating. And the length of the outer support rod 301 is sufficient such that when the outer support rod 301 rotates outwards, the end far from the driving rod 309 is in threaded engagement with the inner wall of the internal thread cylinder 201.

[0036] Working principle: When the equipment needs to install the adjustment foot, the inner threaded cylinder 201 is driven to rotate by rotating the outer cylinder 1, and the inner threaded cylinder 201 drives the rectangular limit block 203 to rotate through the internal rectangular cavity, thereby driving the threaded rod 205 to rotate, so that the threaded rod 205 is fixedly connected with the threaded hole reserved for the equipment. After the threaded rod 205 is screwed into the threaded hole, the upper surface of the inner threaded cylinder 201 is abutted against the outer surface of the equipment, and the adhesive strip 204 on the upper surface of the inner threaded cylinder 201 is bonded to the outer surface of the equipment, thereby assisting the fixation of the inner threaded cylinder 201 and the equipment. Then the worker presses the two pressing blocks 303 at the same time, thereby driving the two connecting rods 304 to squeeze the connecting truncated cone 308 inward, so that the connecting truncated cone 308 pulls the connecting column 305 downward through the lifting column 307, and the annular groove on the outer surface of the connecting column 305 and the driving rod 3 09, drives the outer support rod 301 to rotate inward, so that the outer support rod 301 returns to the rectangular groove provided on the outer surface of the connecting tube 302, thereby contacting the outer support rod 301 and the inner wall of the internal threaded tube 201. After the contact is locked, continue to press the pressing block 303, and drive the outer threaded tube 202 to rotate, so that the outer threaded tube 202 moves on the thread on the inner wall of the internal threaded tube 201, so as to adjust the extended length of the external threaded tube 202. After the adjustment is completed, release the pressing block 303, and the connecting column 305 is driven by the spring 306 to rise upward, thereby driving the outer support rod 301 to rotate outward through the annular groove of the connecting column 305 and the driving rod 309, so that one end of the outer support rod 301 cooperates with the thread in the internal threaded tube 201, realizing the function of auxiliary locking, and finally realizing the installation of the adjustment foot, and adjusting it to a suitable height.
