Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic diagram of a preferred embodiment of an integrated handcart wheel hub provided by this utility model; Figure 2 for Figure 1 The diagram shows a disassembled structural diagram of the main body of the wheel hub. Figure 3 for Figure 2 The diagram shows the structural schematic of the retaining ring section. Figure 4 for Figure 2 The structural schematic diagram of the rear view of the protective steel ring shown shows an integrated handcart wheel hub, including: a hub body 10, a retaining ring 101 provided on the outer side of the hub body 10, and a protective component 20 provided on the outer side of the retaining ring 101.

[0023] The protective component 20 includes a protective steel ring 201 disposed on the outside of the retaining ring 101. A sliding groove 202 is provided on the inner side of the protective steel ring 201. A docking post 203 is provided on the inner side of the sliding groove 202 that can slide up and down along its length. A docking groove 204 is provided on the side of the retaining ring 101 away from the hub body 10.

[0024] With the setting of the docking post 203, the spring 205 provides a continuous upward force. Therefore, when the docking post 203 is connected to the inside of the docking groove 204 and rotated to the left, the docking post 203 will rise on the protruding part of the docking groove 204 under the action of the spring 205, thereby locking the docking post 203 inside the docking groove 204. This allows the protective steel ring 201 to connect with the retaining ring 101. With the setting of the bolt 207, the protective steel ring 201 is fixed on the outside of the retaining ring 101. When the wheel hub is impacted, since the protective steel ring 201 is on the outside of the retaining ring 101, the retaining ring 101 will not easily deform. The protective steel ring 201 can be replaced only when necessary.

[0025] A spring 205 is provided at the bottom of the inner wall of the sliding groove 202, and the top of the spring 205 is fixedly connected to the bottom of the docking column 203.

[0026] The retaining ring 101 has a threaded hole 206 on the side away from the hub body 10, and the protective steel ring 201 is rotatably threadedly connected to a bolt 207 on the side away from the hub body 10.

[0027] The protective steel ring 201 and the retaining ring 101 are prevented from separating by bolts 207, and the protective steel ring 201 and the retaining ring 101 are prevented from rotating by auxiliary bolts 207 between the mating groove 204 and the mating post 203, thereby achieving fixation.

[0028] The inner side of the hub body 10 is provided with a reinforcing plate 102, and the inner side of the hub body 10 is provided with an integrated bearing seat 103. The inner side of the reinforcing plate 102 is fixedly connected to the outer side of the integrated bearing seat 103.

[0029] The integrated bearing housing 103 improves the service life of the wheel hub body 10, and the reinforcing plate 102 improves the impact resistance of the wheel hub body 10.

[0030] A bearing 104 is provided on the inner side of the integrated bearing housing 103, and a rotating rod 105 is provided on the inner side of the bearing 104.

[0031] A dust cover 106 is provided on the side of the integrated bearing housing 103 away from the hub body 10 and on the circumferential side of the rotating rod 105.

[0032] The working principle of the integrated handcart wheel hub provided by this utility model is as follows:

[0033] Step 1: When using, press the connecting post 203 of the protective steel ring 201 inward and connect it to the inside of the connecting groove 204. After it is fully inserted, rotate the protective steel ring 201. When rotating, the connecting post 203 will gradually approach the protrusion of the connecting groove 204. Then, under the action of the spring 205, the connecting post 203 will be engaged in the protrusion of the connecting groove 204, preventing the protective steel ring 201 and the retaining ring 101 from rotating relative to each other. At this time, the bolt 207 also coincides with the threaded hole 206. Tighten it to complete the fixation.

[0034] Step 2: When the wheel hub is impacted, the protective steel ring 201 is located outside the retaining ring 101, so the protective steel ring 201 will bear the impact. Therefore, the retaining ring 101 will not easily deform, and the protective steel ring 201 can be replaced only when necessary.

[0035] Compared with related technologies, the integrated handcart wheel hub provided by this utility model has the following beneficial effects:

[0036] With the installation of the docking post 203, docking groove 204, bolt 207, and threaded hole 206, the protective steel ring 201 is firmly fixed to the outside of the retaining ring 101. When the wheel hub is impacted, the protective steel ring 201 will bear the impact because it is located on the outside of the retaining ring 101. As a result, the retaining ring 101 will not easily deform. The protective steel ring 201 can be replaced only when necessary. The structure is compact, which not only improves the impact resistance of the wheel hub body 10, but also reduces the maintenance cost of the wheel hub.
