Technical Field
[0001] This utility model relates to the field of starter air guide cover technology, specifically a starter air guide cover. Background Technology
[0002] A lawnmower is a mechanical tool used for trimming lawns, vegetation, etc. It consists of a blade disc, engine, wheels, walking mechanism, blades, handle, and control unit. Currently, lawnmower engines are started by a hand-operated starter. When the starter is pulled, it drives the engine crankshaft to rotate through the starter cup, thus starting the engine. At the same time, the starter impeller rotates with the engine crankshaft to provide cooling for the engine, thus achieving the functions of starting and airflow. Therefore, a starter air duct needs to be designed.
[0003] Traditional starter air guide covers are usually fixed with three or more screws, and the screws are installed at a high height, requiring the use of double-ended bolts for support. However, double-ended bolts are quite long and need to run through the entire air guide cover during installation, which increases the complexity and inconvenience of later installation, and also increases the problem of bolt consumption. Utility Model Content
[0004] The purpose of this utility model is to provide a starter air guide cover, which solves the problems of the existing starter air guide cover being cumbersome to install and requiring multiple bolts for fixing, which increases the consumption of bolts in the later stage and is not conducive to rapid installation.
[0005] To achieve the above objectives, a starter air guide cover is provided, including an air guide cover and a crankshaft housing. The bottom of one end of the front of the air guide cover is fitted with the bottom of one end of the back of the crankshaft housing. Mounting lugs are provided on the bottom of both sides of the crankshaft housing. Bolts are provided through the bottom of both sides of the air guide cover and are connected to the mounting lugs.
[0006] According to the aforementioned starter air guide cover, the bottom of one end of the back side of the air guide cover is evenly provided with mesh holes, and the mesh holes are connected to the inside and outside of the air guide cover.
[0007] According to the aforementioned starter air guide cover, four sets of limiting lugs are installed on the inner side of the air guide cover. The interior of each of the four sets of limiting lugs is provided with an intermediate wheel and a drive rope, and the drive rope cooperates with the intermediate wheel.
[0008] According to the aforementioned starter air guide cover, both sides of the bottom of the air guide cover are provided with through holes, and bolts pass through the interior of the through holes.
[0009] According to the starter air guide cover, each of the two sets of mounting lugs has a lug boss at one end near the air guide cover, and the lug boss has a through threaded hole inside, and the lug boss is inserted into the through hole and connected with a bolt.
[0010] According to the starter air guide cover, each of the two sets of mounting lugs has a support block on one side of its front end that is close to each other, and the support block is connected to the crankcase.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the structural design of the air guide cover, bolts, crankcase and mounting lugs, the installation consumption of traditional double-ended bolts can be reduced, and there is no need to use double-ended bolts to achieve the through-operation of the entire air guide cover installation. Finally, through the design of the mounting lugs and the cooperation of the bolts, the support function of the fixed connection between the air guide cover and the crankcase can be realized, which improves the convenience and flexibility of the later installation. Only two thread tightening operations are required during installation, so that the bolts can be directly fixed to the mounting lugs, reducing double-ended bolts, reducing costs, and making the installation simpler and more convenient.
[0012] Finally, through the design and coordination of the limiting lug, intermediate wheel and drive rope, the drive rope can be limited by the addition of the limiting lug, so as to prevent the drive rope from deviating during the pulling process and ensure the stability of the drive rope when pulling in the later stage.
[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the 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.
[0023] Please see Figure 1-6 This utility model provides a technical solution: a starter air guide cover, including an air guide cover 1 and a crankshaft housing 2. The bottom of one end of the front of the air guide cover 1 is attached to the bottom of one end of the back of the crankshaft housing 2. Mounting lugs 3 are provided on the bottom of both sides of the crankshaft housing 2. Bolts 5 are provided through the bottom of both sides of the air guide cover 1, and the bolts 5 are connected to the mounting lugs 3. This solves the problem that the installation of the existing starter air guide cover is relatively cumbersome and requires multiple bolts for fixing, which increases the consumption of bolts in the later stage and is not conducive to quick installation.
[0024] The bottom of one end of the back of the air guide shroud 1 is evenly provided with mesh holes 4, which are connected to the inside and outside of the air guide shroud 1. The mesh holes 4 facilitate the entry of air during operation. Four sets of limiting lugs 6 are installed on the inner side of the air guide shroud 1. The four sets of limiting lugs 6 are respectively provided with intermediate wheels 8 and drive ropes 7. The drive ropes 7 cooperate with the intermediate wheels 8. Through the design of the limiting lugs 6, the installation and limiting of the drive ropes 7 can be easily realized, ensuring the stability of its later operation. At the same time, the drive ropes 7 can also realize the rotation operation of the intermediate wheels 8. There are through holes on the bottom of both sides of the air guide shroud 1, and bolts 5 pass through the through holes to facilitate the installation of bolts 5. In the through-operation, each of the two sets of mounting lugs 3 has a lug boss at one end near the air guide shroud 1, and the lug boss has a through threaded hole inside. The lug boss is inserted into the through hole and connected to the bolt 5. The design of the lug boss makes it easy to insert into the through hole later, which further increases the tightness of the connection between the air guide shroud 1 and the crankcase 2. Finally, the design of the bolt 5 and the through threaded hole can realize the fixed connection between the air guide shroud 1 and the crankcase 2. Each of the two sets of mounting lugs 3 has a support block on one side of the front that is close to each other, and the support block is connected to the crankcase 2, which facilitates the improvement of the stability and firmness of the mounting lugs 3 during later installation.
[0025] Working principle: During use, the operator can directly pick up the air guide cover 1 and above to align it with the crankcase 2. Then, through the design of the through holes on both sides of the bottom of the air guide cover 1, the external of the mounting lug 3 can be easily fitted. Finally, the bolt 5 is taken and screwed into the mounting lug 3 through the through hole thread, and the threaded connection between the air guide cover 1 and the crankcase 2 can be completed. This structural design also reduces the need to tighten the double-ended bolts, thereby reducing the cost of using double-ended bolts and improving the convenience and flexibility of later installation. At the same time, the design of the bolt 5 and the mounting lug 3 increases the firmness of the connection between the air guide cover 1 and the crankcase 2, and it also eliminates the need for the double-ended bolts to penetrate the entire outside of the air guide cover 1, increasing the convenience and flexibility of later installation and use.
[0026] During use, the operator can directly pull the drive rope 7 to drive the intermediate wheel 8 to rotate. The rotation of the intermediate wheel 8 will then rotate the impeller installed on the outside, which will generate air cooling. The design of the air guide shroud 1 will enable the air cooling operation. Finally, the design of the limiting lug will limit the intermediate wheel 8 and the drive rope 7, increasing the stability of the operation of the drive rope 7 in the later stage.
[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
