Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment feet technology, and in particular to an adaptive equipment foot that is easy to assemble and disassemble. Background Technology

[0002] Equipment feet are bases used to fix and stabilize equipment. Their main function is to prevent the equipment from shaking, slipping, and tilting, and they can also be used to adjust the height of the equipment.

[0003] Currently, many pieces of machinery are placed on the ground by adjusting their height using mounting feet. Commonly used mounting feet include... Figure 1 , Figure 2 As shown, the feet of this type of equipment have the following disadvantages:

[0004] The machining process of pad 3 is relatively complex, requiring turning, milling, drilling and tapping, resulting in high machining costs;

[0005] The installation position of screw 9 has high requirements. It is necessary to achieve an effective connection between screw 2 and pad 3, but not to interfere with the spherical floating between screw 2 and pad 3. That is, the end face of screw 9 head cannot be in contact with the cylindrical surface of the annular groove of screw 2. A certain floating space needs to be left, so the installation is relatively troublesome.

[0006] The connection between screw 2 and pad 3 is not very reliable as it relies solely on the point where the head of screw 9 is inserted into the annular groove of screw 2 to hook onto it.

[0007] The two spherical surfaces of screw 2 and pad 3 cannot be guaranteed to always fit together, meaning that the adjusted equipment height is not very stable.

[0008] Therefore, it is necessary to develop an adaptive equipment foot that is easy to process, easy to install, and stable and reliable. Utility Model Content

[0009] (a) Technical problems to be solved

[0010] To address the shortcomings of existing technologies, this utility model provides an adaptive equipment foot that is easy to assemble and disassemble. It employs a structure that uses a wire retaining ring inserted into the hole in the pad and a spherical fit between the pad and the screw, which enables a reliable connection between the screw and the pad. When installing the foot, connecting or disassembling the screw and the pad becomes extremely simple; it can be directly inserted or pulled out. This reduces labor costs, improves installation efficiency, and solves the technical problems of unreliable connection between the screw and the pad and cumbersome installation in existing technologies.

[0011] (II) Technical Solution

[0012] To achieve the above objectives, this utility model provides the following technical solution: a self-adaptive equipment foot that is easy to assemble and disassemble, comprising several equipment bases installed below the equipment, a screw rod being threaded into the center of each equipment base, a pad being provided on the bottom spherical surface of the screw rod, a first hexagonal nut being threadedly connected to the screw rod being installed on the top of the equipment base, an installation groove being machined in the center of each pad, the installation groove comprising a chamfered groove opening, a small diameter groove, and a large diameter groove machined sequentially from top to bottom, a semi-circular retaining ring groove being further machined on the groove wall of the small diameter groove, and a wire retaining ring for holes being installed in the retaining ring groove.

[0013] Furthermore, the top of the screw includes a hexagonal wrench position for turning the screw after the wrench is engaged in the wrench position, so that the equipment base moves up and down along the axis of the screw.

[0014] Furthermore, the screw has an annular groove machined near its bottom, which connects to the screw head machined at the bottom. The diameter of the screw head is larger than the inner diameter of the wire retaining ring for the hole, while the diameter of the annular groove is smaller than the inner diameter of the wire retaining ring for the hole.

[0015] Furthermore, the first hexagonal nut is tightened onto the screw, with its lower surface fitting against the upper surface of the equipment base, thereby locking the relative position of the adjusted screw and the equipment base.

[0016] Furthermore, the pad is a cylinder, and the bottom of its mounting groove, that is, the bottom near the large-diameter groove, is machined with an inner spherical surface. The bottom surface of the screw is also machined with an outer spherical surface. Therefore, the bottom of the screw and the pad are fitted together by the outer spherical surface and the inner spherical surface to form a spherical fit.

[0017] Furthermore, a first central through hole is machined inside the screw, and a second central through hole is machined below the large-diameter groove of the pad. The first central through hole and the second central through hole are located on the same axis. Chemical anchors are inserted and installed in the first central through hole and the second central through hole, and the bottom of the chemical anchors is fixed to the foundation with a chemical agent.

[0018] Furthermore, a flat washer is fitted onto the upper end of the chemical anchor, the bottom surface of the flat washer is in contact with the top surface of the screw, and a second hexagonal bolt is threaded onto the upper end of the chemical anchor, the bottom surface of the second hexagonal bolt is in contact with the top surface of the flat washer and tightened.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, this utility model provides an adaptive device foot that is easy to assemble and disassemble, and has the following beneficial effects:

[0021] This invention provides a self-adaptive equipment foot that is easy to process, install, and is stable and reliable. When installing the foot, connecting or disconnecting the screw and the pad becomes exceptionally simple; it can be directly inserted or pulled out, reducing labor costs and improving installation efficiency. The connection between the screw and the pad is also highly reliable, facilitating equipment movement or transportation and reducing labor input. When the equipment is placed on the ground, even if the workshop floor is not level, the pad can automatically adapt and stably bear the weight of the equipment. Once the equipment is positioned and adjusted to the required height and no further movement is needed, the use of chemical anchors ensures stable equipment height. This foot has a simple design, is easy to install, and is stable and reliable, greatly facilitating production and assembly. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 3-5An easy-to-assemble and disassemble self-adaptive equipment foot includes several equipment bases 101 installed below equipment 1. The equipment base 101 is characterized by a screw rod 2 threadedly connected to its center. A pad 3 is fitted onto the spherical surface of the bottom of the screw rod 2. A first hexagonal nut 4 threadedly connected to the screw rod 2 is installed on the top of the equipment base 101. A mounting groove is machined at the center of the pad 3. The mounting groove includes a chamfered groove 301, a small-diameter groove 302, and a large-diameter groove 303 machined sequentially from top to bottom. A semi-circular retaining ring groove 304 is further machined on the wall of the small-diameter groove 302, and a wire retaining ring 5 is installed within the retaining ring groove 304.

[0030] In the above embodiment, the top of the screw 2 includes a hexagonal wrench position 201 for tightening the screw 2 after the wrench is engaged in the wrench position 201, so that the equipment base 101 moves up and down along the axis of the screw 2; the screw 2 has an annular groove 202 near the bottom, which connects to the screw big end 203 machined at the bottom. The diameter of the screw big end 203 is larger than the inner diameter of the wire retaining ring 5 for the hole, while the diameter of the annular groove 202 is smaller than the inner diameter of the wire retaining ring 5 for the hole; the first hexagonal nut 4 is tightened on the screw 2, and its lower surface is in contact with the upper surface of the equipment base 101, so that the relative position of the adjusted screw 2 and the equipment base 101 is locked.

[0031] In the above embodiment, the pad 3 is a cylinder, and the bottom of its mounting groove, i.e., the bottom near the large-diameter groove 303, is machined with an inner spherical surface 305. The bottom surface of the screw 2 is also machined with an outer spherical surface 204. Therefore, the bottoms of the screw 2 and the pad 3 form a spherical fit through the interaction of the outer spherical surface 204 and the inner spherical surface 305. The screw 2 has a first central through hole 205 machined inside, and the pad 3 has a second central through hole 306 machined below the large-diameter groove 303. The first central through hole 205 and the second central through hole 306 are located on the same axis. Chemical anchors 6 are inserted and installed in the first central through hole 205 and the second central through hole 306. The bottom of the chemical anchors 6 is fixed to the foundation with a chemical agent. A flat washer 7 is fitted onto the upper end of the chemical anchor bolt 6. The bottom surface of the flat washer 7 is in contact with the top surface of the screw 2. A second hexagonal bolt 8 is threaded onto the upper end of the chemical anchor bolt 6. The bottom surface of the second hexagonal bolt 8 is in contact with the top surface of the flat washer 7 and tightened.

[0032] The working principle of the above embodiments is as follows:

[0033] During installation, when the wire retaining ring 5 is inserted into the retaining ring groove 304, the chamfer 301 at the orifice acts as a guide, facilitating installation. Since the diameter of the small-diameter groove 303 is smaller than the center diameter of the wire retaining ring 5, the wire retaining ring 5 will not easily come out of the retaining ring groove 304. Because the diameter of the retaining ring groove 304 is larger than the outer diameter of the wire retaining ring 5, the wire retaining ring 5 can move horizontally within the retaining ring groove 304. When the screw 2 is inserted into the mounting slot of the pad 3, because the diameter of the screw's large end 203 is larger than the inner diameter of the wire retaining ring 5, the wire retaining ring 5 will expand and undergo elastic deformation within the retaining ring groove 304. After the screw's large end 203 passes through, the annular groove 202 is positioned at the location of the wire retaining ring 5. Because the diameter of the annular groove 202 is smaller than the inner diameter of the wire retaining ring 5, the wire retaining ring 5 returns to its original shape. In this way, the retaining groove 304 of the pad 3 locks the wire retaining ring 5 for the hole, and the wire retaining ring 5 for the hole locks the screw 2, thus achieving a reliable connection between the screw 2 and the pad 3.

[0034] Because the workshop floor is not level and may even tilt in multiple directions, the feet of equipment 1 need to be able to accommodate installation under such conditions. The spherical fit between pad 3 and screw 2 can meet this requirement. Pad 3 and screw 2 can float at a certain angle of 360 degrees with the center of the sphere as the reference. The large-diameter groove 303 of pad 3 also provides enough space for floating. When the bottom surface of pad 3 tilts in any direction and is not perpendicular to the axis of screw 2, the spherical fit between pad 3 and screw 2 is still good. Therefore, pad 3 can still stably bear the weight of equipment 1.

[0035] Once the equipment 1 is positioned, the screw 2 can be turned by engaging the wrench in position 201, allowing the equipment base 101 to move up and down along the axis of the screw 2, thus adjusting the height of the equipment 1. When the desired height is achieved and no further movement is needed, the chemical anchor 6 passes through the central through hole 205 of the screw 2 and the central through hole 306 of the pad 3. The bottom of the chemical anchor 6 is fixed to the foundation with a chemical agent. The flat washer 7 is fitted onto the chemical anchor 6, with its bottom surface fitting against the top surface of the screw 2. The second hexagonal nut 8 is threaded onto the chemical anchor 6 and tightened, with its bottom surface fitting against the top surface of the flat washer 7. In this way, the spherical surfaces of the screw 2 and the pad 3 remain in contact, ensuring that the adjusted height of the equipment 1 is stable.
