Technical Field

[0001] This utility model relates to the field of automotive engine impeller technology, and in particular to a high-temperature resistant automotive engine impeller. Background Technology

[0002] With the development of automotive engine technology and the progress of the times, the automotive engine impeller, as an important component of the automotive engine, mainly performs the bidirectional conversion of fluid kinetic energy and mechanical energy. Moreover, there are many materials that can be used to make automotive engine impellers, including high-temperature resistant materials, high-hardness materials, high-strength materials, etc.

[0003] According to the currently published patent number 201921661324.4, the automotive engine impeller, by setting the inner cavity of the drive shaft mounting hole to be adapted to the outer surface of the drive shaft, enables the drive shaft to be installed into the inner cavity of the drive shaft mounting hole, allowing the drive shaft to drive the drive shaft mounting hole to rotate, and preventing excessive gap between the drive shaft mounting hole and the drive shaft from causing shaking during operation, thus increasing the stability of the equipment, the existing automotive engine impeller, in use, only restricts the range of restriction in a single place, which makes it easy for the shaft to generate relative movement after long-term friction with the hole, affecting the subsequent use effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing automotive engine impellers, which, due to their limited limitation at a single point during use, are prone to relative motion caused by long-term friction between the shaft and the hole, thus affecting subsequent performance. Therefore, this invention proposes a high-temperature resistant automotive engine impeller.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-temperature resistant automobile engine impeller, comprising:

[0007] The impeller body has a connecting rod inserted into its bottom end, and a second limiting groove is provided at the top end of the connecting rod. A fixing block is fixed to the outer wall of the connecting rod, and an end cap is fitted onto the outer wall of the connecting rod. A first limiting groove is provided at the bottom end of the impeller body, and an insert rod is fixed to the top end of the inner side of the impeller body.

[0008] Preferably, the top end of the impeller body is provided with blades.

[0009] Preferably, the inner wall of the first limiting groove is in contact with the outer wall of the fixing block, and four sets of the first limiting groove are provided.

[0010] Preferably, the upper part of the inner wall of the end cap is threaded to the impeller body, and the lower part of the inner wall of the end cap is threaded to the connecting rod.

[0011] Preferably, the insertion rod has a cuboid structure, and the insertion rod and the second limiting groove are connected by insertion.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by setting up a fixing block, connecting rod, impeller body, etc., after the connecting rod is inserted into the inner side of the impeller body, the second limiting groove is inserted into the cuboid structure of the rod. At the same time, the fixing block enters the corresponding first limiting groove, realizing multi-point limiting work. This makes the limiting range between the connecting rod and the impeller body large, and it is not easy for the relative movement to occur due to long-term friction between the connecting rod and the rod. Therefore, it can effectively improve the long-term use effect of the impeller. Attached Figure Description

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1-3A high-temperature resistant automotive engine impeller includes an impeller body 1. A connecting rod 4 is inserted into the bottom end of the impeller body 1, and a second limiting groove 8 is formed at the top end of the connecting rod 4. A fixing block 5 is fixed to the outer wall of the connecting rod 4, and an end cap 6 is sleeved on the outer wall of the connecting rod 4. A first limiting groove 3 is formed at the bottom end of the impeller body 1. The inner wall of the first limiting groove 3 fits against the outer wall of the fixing block 5, and four sets of first limiting grooves 3 are provided. After the fixing block 5 moves with the connecting rod 4, it can enter the corresponding first limiting groove 3 to complete the limiting work. A rod 7 is fixed to the inner top of the body 1. The rod 7 has a cuboid structure and is inserted into the second limiting groove 8. After the connecting rod 4 is inserted into the inner side of the impeller body 1, the second limiting groove 8 can be sleeved on the outer side of the rod 7 to achieve the purpose of limiting the impeller body 1 and the connecting rod 4. The top of the impeller body 1 is provided with blades 2. Both the impeller body 1 and the blades 2 are made of high temperature resistant materials. The high temperature resistant materials are available in the prior art, so they will not be described in detail. This makes the high temperature resistance of the automobile engine impeller excellent.

[0021] The upper part of the inner wall of the end cover 6 is threaded to the impeller body 1, and the lower part of the inner wall of the end cover 6 is threaded to the connecting rod 4. The end cover 6, the outer wall of the connecting rod 4, and the bottom of the impeller body 1 are connected by threaded connection by hand, so that the end cover 6 can abut against the fixing block 5, thus the stability between the connecting rod 4 and the impeller body 1 is better.

[0022] Working principle: In use, the operator first inserts the connecting rod 4 into the inner side of the impeller body 1. The second limiting groove 8 at the top of the connecting rod 4 can then be fitted onto the outer side of the insert rod 7. At the same time, the fixing block 5 moves with the connecting rod 4 and enters the corresponding first limiting groove 3 to complete the limiting work. Subsequently, the operator manually performs a synchronous threaded connection between the end cover 6 and the outer wall of the connecting rod 4 and the bottom end of the impeller body 1, so that the end cover 6 can abut against the fixing block 5. This results in good stability between the connecting rod 4 and the impeller body 1. (It should be noted that the specific model and specifications of the electrical parts involved in this solution need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.)

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
