Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sprocket wheels, and in particular relates to a sprocket wheel structure with a protective structure. Background Art
[0002] A sprocket is a wheel with cog-type sprocket teeth. It is a mechanical part with a specific tooth shape. It is used to mesh with blocks with accurate pitch on the link chain or cable to achieve power transmission. The sprocket needs to have sufficient strength and wear resistance to ensure stability and durability when transmitting power and movement. At the same time, parameters such as the number of teeth, diameter and tooth shape of the sprocket will affect the transmission effect.
[0003] The sprocket structures currently on the market have the following problems when applied:
[0004] 1. In the actual use of the traditional sprocket structure, usually the blocks with accurate pitch on the chain ring or cable are meshed to transmit power, but the outer cylinder structure is directly exposed to the outside, which is easy to cause wear after a long time of operation. Therefore, there is no protective structure for the outer cylinder when in use;
[0005] 2. When most sprocket structures are used, the sprocket body is often an integrated structure. Once the outside or inside of the sprocket body is damaged to varying degrees, it is not convenient for the staff to repair it later, and it is also time-consuming and laborious. Therefore, it does not have a replaceable structure when used. Utility Model Content
[0006] The utility model aims to provide a sprocket structure with a protective structure to solve the technical problems raised in the background technology.
[0007] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: a sprocket structure with a protective structure, comprising a sprocket body and an outer cylinder, the top of the sprocket body is connected to the outer cylinder, a bottom plate is provided on the outside of the outer cylinder, a reinforcing plate is provided above the bottom plate, a top plate is provided above the reinforcing plate, a magnetic ring is provided at the bottom of the top plate, the magnetic ring is embedded in the top of the outer cylinder, an insertion rod is provided at the bottom of the bottom plate, the insertion rod is inserted into the outside of the sprocket body, and a reinforcing ring is provided on the outside of the reinforcing plate.
[0008] Preferably, an inner cylinder is provided inside the outer cylinder, a keyway is provided inside the inner cylinder, a limit plate is provided outside the inner cylinder, a cross clamp is provided at the bottom of the limit plate, the limit plate and the cross clamp are inserted into the outer cylinder, a hexagon socket bolt is provided inside the outer cylinder, a thread groove is provided outside the inner cylinder, and the hexagon socket bolt is threadedly connected to the thread groove.
[0009] Preferably, a slot is provided on the top of the sprocket body, a metal slot is provided on the top of the outer cylinder, an insert rod is provided inside the slot, and the magnetic ring is adsorbed inside the metal slot by magnetic force.
[0010] Preferably, the top of the bottom plate is connected to the lower ring body, the bottom of the top plate is connected to the upper ring body, a reinforcing plate is provided on the top of the lower ring body, and an upper ring body is provided on the top of the reinforcing plate.
[0011] Preferably, a limiting groove and a cross-clip groove are provided inside the outer cylinder, the limiting plate is inserted into the limiting groove, and the cross-clip plate is embedded in the cross-clip groove.
[0012] Preferably, a mounting groove and a through hole are provided on the outside of the outer cylinder, a hexagon socket bolt is provided inside the mounting groove, and the hexagon socket bolt passes through the through hole.
[0013] The sprocket structure with a protective structure of the utility model has the following advantages:
[0014] 1. The sprocket structure with a protective structure can protect the outer cylinder by installing a reinforcing plate, a reinforcing ring, a top plate, a bottom plate, an insertion rod, and a magnetic ring on the outside of the outer cylinder. Before using the sprocket body, the protective structure is first taken out, and the bottom plate and the top plate are sleeved on the outside of the outer ring body, so that the insertion rod and the magnetic ring are inserted into the sprocket body and the outside of the outer cylinder. At the same time, a reinforcing plate and a reinforcing ring are installed between the top plate and the bottom plate, which can be used to improve the connection strength of the protective structure. Therefore, when in use, it has a structure for protecting the outer cylinder, and the protective effect is strong;
[0015] 2. This sprocket structure with a protective structure can replace a damaged sprocket structure by installing an inner cylinder, a limit plate, a cross clamp, a mounting groove, an inner hexagonal bolt and other structures inside the inner cylinder. When the sprocket structure is worn during long-term use, it is only necessary to reversely twist the inner hexagonal bolt inside the mounting groove to remove the limit plate and the cross clamp outside the inner cylinder from the outer cylinder. In this way, the outer cylinder and the inner cylinder can be disassembled, and a new outer cylinder or inner cylinder can be taken out and installed again with the inner hexagonal bolt. In this way, the damaged sprocket structure can be replaced at the same time, and the operation is also relatively simple. BRIEF DESCRIPTION OF THE DRAWINGS
