[0003] The compressor is usually driven by a single-cylinder diesel engine. After the compressed air in the air tank is used, the compressor needs to increase its power, which requires the diesel engine to increase its power as well, that is, the position of the throttle lever needs to be adjusted. Currently, a cylinder is fixed on the outer wall of the diesel engine, and then the throttle lever is driven by the cylinder to move. This structure is nonlinear and can easily cause problems such as excessive fuel consumption and damage to the diesel engine. Utility Model Content

[0004] In view of this, the utility model aims to provide an air compressor and a throttle adjustment device for its power source, so as to achieve the effect of linear adjustment of the throttle lever and achieve the purpose of reducing fuel consumption.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a power source throttle adjustment device, including a hanging plate and a support plate, the hanging plate and the power source are relatively fixed, a positioning piece is provided on the support plate, the positioning piece is swingably connected to the support plate, the positioning piece is connected to the hanging plate, a power piece is connected to the support plate, the power piece is connected to a driving rod, an adjustment seat is threadedly connected to the driving rod, a support rod is connected to the adjustment seat, and the support rod is ball-connected to the throttle rod.

[0006] To implement the above technical solution, when the power piece is turned on, the power piece drives the driving rod to rotate, and the adjusting seat moves along the length direction of the driving rod through the transmission action of the thread. Since the throttle lever moves along an arc, the support plate swings along the connection with the positioning piece. When the throttle lever moves to both ends of the stroke, at the same time, the end of the support rod away from the adjusting seat tends to swing toward the power source, and since the throttle lever is rigid, the end of the support rod away from the adjusting seat will be deflected toward the support plate; similarly, when the throttle lever moves to the middle of the stroke, the support rod is reset, thereby moving the adjusting seat from one end of the driving rod to the other end of the driving rod, thus completing the full stroke of the throttle lever. Since it is threaded transmission, the throttle lever can move linearly, which not only reduces fuel consumption but also effectively controls the damage to its power source.

[0007] As a preferred solution of the utility model, the support plate is connected with a support seat, the two support seats are respectively located at two ends of the driving rod, and the driving rod is rotatably connected to the support seat through a bearing.

[0010] To implement the above technical solution, the support rod is passed through the connecting hole, and the distance between the end of the support rod and the adjusting seat can be adjusted to adapt to throttle levers in different positions. The friction between the two locking sleeves and the connecting plate can then be used to fix the support rod and the connecting plate, thereby improving practicality.

[0011] As a preferred solution of the utility model, an installation groove is provided on the hanging plate, a positioning ball is rotatably connected to the positioning piece, a positioning bolt is threadedly connected to the positioning ball, the positioning ball is in contact with the outer wall of the support plate, the positioning piece passes through the installation groove and is threadedly connected to a mounting screw sleeve, and the two mounting screw sleeves are tightly pressed against the hanging plate.

[0012] To implement the above technical solution, the hanging plate is fixed, the positioning piece is passed through the installation groove, and then the installation screw sleeve is pressed against the outer wall of the hanging plate. The friction force generated realizes the positioning of the positioning piece, thereby facilitating the adjustment of the position of the support plate and improving practicality.

[0013] As a preferred solution of the utility model, a position sensor is connected to the support plate, and the position sensor corresponds to the adjustment seat.

[0014] To implement the above technical solution, a position sensor is provided so that workers can monitor the position of the adjustment seat at any time.

[0015] As a preferred solution of the utility model, the adjustment seat includes an adjusting screw sleeve, a fixing plate, a fixing bolt, and a fixing sleeve. The adjusting screw sleeve is threadedly connected to the driving rod, and the fixing bolt passes through the adjusting screw sleeve and the fixing plate and is threadedly connected to the fixing sleeve to fix the adjusting screw sleeve and the fixing plate.

[0016] Implementing the above technical solution makes it easier to install the fixing plate and reduces maintenance costs.

[0017] As a preferred solution of the utility model, the driving rod is connected to the power member through a coupling.

[0018] The implementation of the above technical solution makes it easy to connect the power member with the driving rod, and at the same time, makes it easy to match the driving member with power members of different models, thereby improving practicality.
