Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engines, and more specifically to an engine throttle cable plate. Background Art
[0002] The engine throttle basically includes two forms, namely electronic throttle and cable throttle. Each of these two forms has its own advantages and disadvantages. The electronic throttle uses computer control to adjust the throttle opening and closing, while the cable throttle relies on a steel wire to pull the throttle valve to achieve. The electronic throttle has no steel wire cable, and its structure is relatively complex; while the cable throttle includes a steel wire cable, and its structure is relatively simple.
[0003] For an excavator, due to the relatively complex working scenario and harsh working conditions, in order to reduce the failure rate, it is a more common choice to use the traditional cable throttle. When arranging the throttle cable, it is necessary to arrange the specific structure according to the model and type of the engine. However, sometimes due to the engine structure limitation, it is not easy to set the cable structure at the cable plate, and the engine needs to be modified. However, this modification requires the authorization of the engine factory. If the authorization is not obtained, it will be very troublesome to set the cable plate. Summary of the Invention
[0004] One advantage of the utility model is to provide an engine throttle cable plate, which has a simple structure and is convenient to use. The auxiliary plate cleverly changes the direction of the cable, so that it is easy to set the cable structure without modifying the engine.
[0005] To achieve at least one of the above advantages of the utility model, the utility model provides an engine throttle cable plate. A cable plate is provided on the engine, and an auxiliary plate is installed on the cable plate.

The installation seat of the throttle cable is arranged on the installation slot, and the cable of the throttle cable is connected to the third through hole.
[0008] According to an embodiment of the utility model, a limiting block is provided on the side of the auxiliary plate, and a limiting groove is provided at the corresponding position of the cable plate. The limiting block and the limiting groove are connected in an interference fit manner.
[0009] According to an embodiment of the utility model, another first through hole is provided at the other end of the auxiliary plate. The first through hole corresponds to the cable hole on the cable plate, and the first through hole and the cable hole are connected by a pin shaft.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation to the present invention.
[0021] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of one element can be one, while in other embodiments, the number of this element can be multiple.

[0022] The present invention provides an engine 1 throttle cable plate 2. A cable plate 2 is provided on the engine 1. An auxiliary plate 3 is installed on the cable plate 2. A first through hole 31 is provided in the middle of the auxiliary plate 3. The bolt of the cable plate 2 passes through the first through hole 31. The auxiliary plate 3 extends downward from the first through hole 31, and a third through hole 33 is provided at its end. The engine 1 also includes a housing 5. An installation plate 4 is provided on the housing 5. An installation slot 42 is provided on the installation plate 4. The installation seat of the throttle cable is arranged on the installation slot 42. The cable of the throttle cable is connected to the third through hole 33. A limiting block 34 is provided on the side of the auxiliary plate 3. A limiting slot is opened at the corresponding position of the cable plate 2. The limiting block 34 and the limiting slot are connected in an interference fit manner. Another first through hole 31 is provided at the other end of the auxiliary plate 3. The first through hole 31 corresponds to the cable hole on the cable plate 2, and the first through hole 31 and the cable hole are connected by a pin shaft. The third through hole 33 and the installation slot 42 are on the same horizontal line. An installation through hole 41 is provided on the installation plate 4. The installation through hole 41 corresponds to the bolt hole on the engine 1 housing 5 and is connected by a bolt.
[0023] Embodiment 1 of the present invention is as follows:
[0024] For the engine 1 throttle cable plate 2, a cable plate 2 is provided on the engine 1. Due to the limitation of the engine 1 structure, the cable plate 2 rotates clockwise to adjust the throttle, but the cable structure needs to be installed on the upper part. When the cable plate 2 is pulled to the right, due to the current structure limitation of the engine 1, an installation plate 4 cannot be provided on the right side of the cable plate 2.
[0025] To solve the above problems, an auxiliary plate 3 is installed on the cable plate 2. The upper half of the auxiliary plate 3 has the same structure as the cable plate 2. Its lower part extends downward. A first through hole 31 is provided in the middle. The bolt of the cable plate 2 passes through the first through hole 31 and rotates around the bolt and the first through hole 31.
[0026] The auxiliary plate 3 extends downward from the first through hole 31 to the end and is provided with a third through hole 33. The third through hole 33 has the same function as the wire-drawing hole on the original wire-drawing plate 2, that is, it is connected to the throttle wire;
[0027] By means of the auxiliary plate 3, the connection position of the throttle wire is transferred from above to below. The wire-drawing plate 2 also rotates clockwise, but the pulling direction is changed from pulling to the right to pulling to the left, effectively solving the problem that there is no position on the right side of the wire-drawing plate 2 to set the mounting plate 4.
[0028] The side of the auxiliary plate 3 is provided with a limit block 34, and a limit groove is opened at the corresponding position of the wire-drawing plate 2. The limit block 34 and the limit groove are connected in an interference fit manner. Through the connection of the limit block 34 and the limit groove, it is ensured that the auxiliary plate 3 and the wire-drawing plate 2 will not shift. The other end of the auxiliary plate 3 is provided with a first through hole 31. The first through hole 31 corresponds to the wire-drawing hole on the wire-drawing plate 2, and the first through hole 31 and the wire-drawing hole are connected by a pin shaft. The pin shaft can also be replaced by a bolt for firm connection.
[0029] A mounting plate 4 is provided on the housing 5 of the engine 1. The mounting plate 4 is located on the left side of the auxiliary plate 3. The mounting plate 4 is provided with a mounting through hole 41. The mounting through hole 41 corresponds to the bolt hole on the housing 5 of the engine 1 and is connected by a bolt. The mounting plate 4 is provided with a mounting slot 42. The mounting seat of the throttle wire is arranged on the mounting slot 42. The wire of the throttle wire is connected to the third through hole 33. The third through hole 33 and the mounting slot 42 are on the same horizontal line.
[0030] It should be noted that the terms "first", "second" and "third" in the present invention are only for descriptive purposes, do not represent any order, and cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.
