Description

Technical Field

[0001] The invention relates to the field of supporting feet of equipment, in particular to a foot with a Teflon pad. Background Art

[0002] It is more laborious to adjust the load-bearing capacity of existing anchors. At the same time, the anchors need to be fixed to the bottom of the equipment, which often involves drilling. Iron filings generated during drilling may enter the screw of the anchor and get stuck in the thread, which will damage the anchor and reduce its lifespan. Summary of the invention

[0003] The problem to be solved by the present invention is to provide a foot with a Teflon pad, which can reduce the wear of the foot by iron filings when the foot is assembled with equipment and increase the service life of the foot.

[0004] In order to solve the above problems, the present invention provides a foot with a Teflon pad. In order to achieve the above purpose, the technical solution adopted by the present invention to solve the technical problem is:

[0005] A foot with a Teflon pad comprises: a foot in contact with the ground; a pad arranged on the foot; a load-bearing screw vertically arranged above the foot, the bottom of the load-bearing screw is provided with a ball head, and the upper surface of the pad is provided with a pit in contact with the ball head; a fixing plate arranged horizontally and assembled with the load-bearing screw through an internal thread; a washer, an upper washer and a lower washer connected to the thread of the load-bearing screw are respectively provided above and below the assembly point of the fixing plate and the load-bearing screw, and the upper washer and the lower washer are in contact with the fixing plate; the pad, the upper washer and the lower washer are made of Teflon material.

[0006] The beneficial effects of adopting the above technical solution are: Teflon material has an extremely low friction coefficient, so it can be used for lubrication, and its texture is relatively soft. The pit can play a good limiting role on the ball head, but it does not limit the freedom of rotation of the ball head around the vertical line. A washer with an internal thread is installed above and below the connecting and moving part of the fixed plate and the load-bearing screw. When the foot is installed or adjusted with the equipment, if iron filings fall, some of them will be stuck in the washer first. Because the washer material is softer than the load-bearing screw, the external thread of the load-bearing screw will not be damaged. If there are still iron filings entering the ball head, they will also be stuck in the pit of the pad, and the damage to the ball head will be very small. The external thread and ball head of the load-bearing screw, which need the most maintenance in the foot, are guaranteed.

[0007] As a further improvement of the present invention, the foot includes a bottom pad in contact with the ground, and also includes a conical cover plate located above the bottom pad, and the pad block is arranged between the bottom pad and the conical cover plate.

[0008] The beneficial effect of adopting the above technical solution is that the bottom foot is detachable, which is convenient for replacing and cleaning the pad. At the same time, the pad is arranged between the ball head and the bottom pad, playing a relay role, and alleviating the high pressure of the bottom pad.

[0009] As a further improvement of the present invention, the lower surface of the conical cover plate is provided with a concave receiving pit, the gasket is located in the receiving pit, the load-bearing screw passes through the top of the conical cover plate, and an adjusting nut is provided above the conical cover plate. The lower surface of the adjusting nut is in contact with the top of the conical cover plate, and the adjusting nut is assembled with the load-bearing screw through an internal thread.

[0010] The beneficial effect of adopting the above technical solution is that when the wrench turns the adjusting nut, the ball head at the bottom of the load-bearing screw rotates on the pad, and the lubricating property of Teflon can greatly reduce the wrench output.

[0011] As a further improvement of the present invention, the bottom pad is disc-shaped and made of rubber, and the edge of the conical cover plate is provided with a rib extending downward and in contact with the bottom pad.

[0012] The beneficial effect of adopting the above technical solution is that the retaining edge also plays a role in limiting the translational shedding of the bottom pad.

[0013] As a further improvement of the present invention, the horizontal cross-sectional profile of the pit is circular, the diameter of the ball head is larger than the diameter of the horizontal cross-sectional profile of the pit, and the junction between the top of the pit and the upper surface of the pad is provided with a circle of transition chamfer.

[0014] The beneficial effects of adopting the above technical solution are: the transition chamfer increases the contact area with the ball head and reduces the pressure.

[0015] As a further improvement of the present invention, when the ball head is assembled with the pit, there is a gap between the ball head and the inner wall of the pit, and the ball head does not contact the conical cover plate.

[0016] The beneficial effect of adopting the above technical solution is that the ball head does not wear against the conical cover plate in contact, and if any debris falls into the conical cover plate, the debris will fall into the gap during rotation, reducing damage to the ball head.

[0017] As a further improvement of the present invention, there are vertical connecting screws on the conical cover plate that do not contact the receiving pit, and the connecting screws connect the conical cover plate to the bottom pad.

[0018] The beneficial effect of adopting the above technical solution is that the connecting screws facilitate the detachable connection of the bottom pad and the conical cover plate, and play a role in wrapping and limiting the pad.

[0019] As a further improvement of the present invention, the internal thread where the fixing plate and the load-bearing screw are assembled has a vertically extending expansion part, the expansion part has a vertically penetrating through hole, and the upper washer and the lower washer have through holes coaxial with the through hole.

[0020] The beneficial effect of adopting the above technical solution is: because the expansion part is the part assembled with the load-bearing screw, the pressure and torsional force here are relatively large. The expansion part first expands the vertical thickness to facilitate the arrangement of the internal thread and improve the structural strength. The upper washer and the lower washer further increase the upper and lower thickness of the expansion part, thereby improving the structural strength here, and the corresponding foot can withstand a larger equipment weight.

[0021] As a further improvement of the present invention, the through hole is a second step hole and a first step hole respectively provided on the upper gasket and the lower gasket, the large hole of the second step hole faces upward, and the large hole of the first step hole faces downward, and the upper gasket and the lower gasket have the same size and shape.

[0022] The beneficial effects of adopting the above technical solution are: the stepped hole facilitates the fastener to be in a countersunk state after assembly, reducing surface protrusions, and at the same time, the upper washer and the lower washer can actually be the same part, increasing versatility and reducing manufacturing costs.

[0023] As a further improvement of the present invention, the fixing plate has a pair of adjacent vertical edges, the position of the expansion portion does not coincide with the centroid of the fixing plate, and the fixing plate has a plurality of through fixing holes.

[0024] The beneficial effect of adopting the above technical solution is that the adjacent vertical edges are convenient for corresponding to the top angles of the bottom of the fixed equipment, and the fixing holes are convenient for fasteners to pass through, so that the foot and the equipment are firmly fixed.
