Description

Technical Field

[0001] This utility model relates to the field of abrasive materials technology, and in particular to a wear-resistant steel forging. Background Technology

[0002] Wear-resistant steel forgings are steel forgings with "wear resistance" as their core performance indicator. They are mainly used in industrial settings where strong friction, impact, or wear is required.

[0003] For example, Chinese utility model patent CN210846599U discloses a wear-resistant steel forging, including a first hemisphere, a cylinder, a second hemisphere, and multiple annular wear-resistant bodies. The first hemisphere, cylinder, and second hemisphere are arranged sequentially. The outer surface of the cylinder has an external thread, and the inner side of each annular wear-resistant body has an internal thread matching the external thread. The multiple annular wear-resistant bodies are sequentially sleeved on the cylinder and threadedly connected to the cylinder. The m-th annular wear-resistant body extends outward uniformly from the side closest to the (m+1)-th annular wear-resistant body to form an annular extension, and the (m+1)-th annular wear-resistant body is recessed inward from the side closest to the m-th annular wear-resistant body to form an annular groove, where M is a positive integer. The annular extension and the annular groove are slidably connected along their own axis, and the annular extension and the annular groove have equal axial lengths along the cylinder. This utility model can prevent dust from entering the gaps between the annular wear-resistant bodies when the wear-resistant steel forging impacts with a wear-resistant liner, thereby avoiding affecting the connection between the annular wear-resistant bodies and the cylinder.

[0004] However, when the above-mentioned wear-resistant steel forging is used, the grooves of m and m+1 are used to achieve the purpose of dust entry. However, under continuous impact, the spiral connection alone is not enough to stabilize the position of the annular wear-resistant body. During repeated vibration and impact, the annular wear-resistant body will loosen. Therefore, a wear-resistant steel forging is needed. Utility Model Content

[0005] The purpose of this invention is to provide a wear-resistant steel forging that solves the problem of loosening of the annular wear-resistant body due to impact and vibration in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant steel forging, comprising a wear-resistant cylinder with threaded ribs on its outer wall, and a first annular wear-resistant body and a second annular wear-resistant body spirally connected to the outer wall of the wear-resistant cylinder. The second annular wear-resistant body has a sliding groove inside that matches the extension portion provided at the end of the first annular wear-resistant body. The extension portion of the first annular wear-resistant body abuts against a protrusion inside the second annular wear-resistant body to prevent the first annular wear-resistant body and the second annular wear-resistant body from vibrating and loosening.

[0007] Preferably, the first annular wear-resistant body includes a left wear-resistant ring, a retaining ring, and a mating groove. The end of the extension of the left wear-resistant ring is connected to a retaining ring, and a mating groove that mates with a protrusion is provided between the retaining rings.

[0008] Preferably, the second annular wear-resistant body includes a right wear-resistant ring and an adapter groove, wherein the right wear-resistant ring has an adapter groove inside that matches the extension of the first annular wear-resistant body.

[0009] Preferably, the right wear-resistant ring has a groove that matches the protrusion.

[0010] Preferably, the bump is connected to the right wear-resistant ring via an elastic element.

[0011] Preferably, the cross-section of the protrusion is triangular, and the triangular inclined surface of the protrusion is provided with a quadrilateral plane parallel to the axis of the wear-resistant cylinder.

[0012] Preferably, the elastic element is a spring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The user rotates the turntable to drive the rotating shaft, which in turn drives the second bevel gear to rotate under the constraint of the mating block. This causes the first bevel gear, which is in mesh with the first bevel gear, to rotate under the constraint of the mating block. This causes the connecting column, which is helically connected inside the first bevel gear, to move the caster body, thus achieving the purpose of lifting and lowering. When subjected to gravity, the turntable provides elastic force through the telescopic rod to hold the locking plate in place, so that the serrations of the locking plate engage with the toothed grooves of the locking plate, thereby preventing the rotating shaft from reversing and locking the caster body and the connecting column.

[0021] 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.

[0022] This utility model relates to a wear-resistant steel forging, such as Figure 1-5 As shown, the device includes a wear-resistant cylinder 1 with threaded ribs on its outer wall, and a first annular wear-resistant body 2 and a second annular wear-resistant body 3 spirally connected to the outer wall of the wear-resistant cylinder 1. The first annular wear-resistant body 2 and the second annular wear-resistant body 3 can be rotated and twisted on the outer wall of the wear-resistant cylinder 1. When the second annular wear-resistant body 3 is twisted to half the position of the wear-resistant cylinder 1, the first annular wear-resistant body 2 is then twisted to make the end of the first annular wear-resistant body 2 fit with the corresponding end of the second annular wear-resistant body 3. The interior of the second annular wear-resistant body 3 has a groove corresponding to the end of the first annular wear-resistant body 2. The sliding groove is designed to match the extension portion. The interior of the second annular wear-resistant body 3 is provided with a protrusion 4 that abuts against the extension portion of the first annular wear-resistant body 2. When the end face of the first annular wear-resistant body 2 is in contact with the end face of the second annular wear-resistant body 3, the extension portion of the first annular wear-resistant body 2 will also extend into the sliding groove of the second annular wear-resistant body 3, so that the extension portion of the first annular wear-resistant body 2 and the protrusion 4 are used in conjunction to achieve the purpose of reverse locking, and to prevent the first annular wear-resistant body 2 and the second annular wear-resistant body 3 from sliding loose due to vibration.

[0023] Among them, such as Figure 4-5 As shown, the first annular wear-resistant body 2 includes a left wear-resistant ring 21, a retaining ring 22, and a mating groove 23. The retaining ring 22 is fixedly provided on the extension of the left wear-resistant ring 21, and the mating groove 23 is provided between the retaining rings 22. The second annular wear-resistant body 3 includes a right wear-resistant ring 31 and an adapter groove 32. The adapter groove 32, which is parallel to the axis of the retaining ring 22, is opened inside the right wear-resistant ring 31. When the first annular wear-resistant body 2 and the second annular wear-resistant body 3 are fitted together, the retaining ring 22 and the mating groove 23 are inserted into the adapter groove 32. A protrusion 4 connected by an elastic element is provided at the deepest part of the adapter groove 32. The cross-section of the protrusion 4 is triangular. The relative position of the triangular inclined surface is a rectangular surface parallel to the axis of the wear-resistant cylinder 1. When the retaining ring 22 and the mating groove 23 rotate in one direction, they abut against the triangular inclined surface of the protrusion 4 so that the protrusion 4 retracts into the sliding groove opened in the right wear-resistant ring 31. When the relative position of the rotation is reached, the protrusion 4 will be inserted into the mating groove 23 due to the elastic element. At this time, the rotation position of the first annular wear-resistant body 2 can be locked to prevent it from vibrating and sliding in the opposite direction. The retaining ring 22 will abut against the relative position of the triangular inclined surface of the protrusion 4 to lock the position of the first annular wear-resistant body 2 and the second annular wear-resistant body 3 connected to the wear-resistant cylinder 1.

[0024] The protrusion 4 can be a spring, an elastic rubber component, or an elastic sheet; in this embodiment, a spring is preferred.

[0025] In practical use: by the user rotating the turntable 7 to drive the rotating shaft 6, the second bevel gear 5 rotates under the restriction of the docking block 4, causing the meshing first bevel gear 3 to rotate under the restriction of the docking block 4, so that the connecting column 2, which is spirally connected inside the first bevel gear 3, drives the caster body 1 to move, thereby achieving the purpose of lifting. When subjected to gravity, the turntable 7 provides elastic force through the telescopic rod 9 to hold the locking disc 10, so that the serrations of the locking disc 10 are engaged in the toothed groove of the locking disc 8, thereby restricting the rotation of the rotating shaft 6 to reverse, and achieving the purpose of locking the caster body 1 and the connecting column 2.
