Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cab tilt pump device used for a cab over truck.

[0002]

[Prior art]

 Generally, in a cab-over truck, a cab-tilt pump device is equipped in the case of a cab-tilt type.

FIG. 4 shows an example of a conventional cab tilt pump device, in which 1 is a tilt pump body, 2 is a drive motor for the tilt pump body 1, and 3 is a drive rod for manually operating the tilt pump body 1. Reference numeral 4 denotes a short tubular socket, one end of which is pivotally supported by a bracket 5 of the tilt pump main body 1 by a shaft 11 and one end side required position is connected to a drive rod 3 for manual operation by a shaft 12; It is a dustproof cover that covers one end side of the drive rod 3 and the socket 4, and the tilt motor body 1 is normally driven by the drive motor 2 to carry out the cab tilt. If the drive motor 2 fails, insert a tool 7 such as a screwdriver into the open end of the socket 4, and attach the socket 4 to the bracket 5 at the pivot point. As a fulcrum, the tilt pump main body 1 is operated by reciprocating up and down and driving the manual operation drive rod 3 of the tilt pump main body 1 to perform a cab tilt.

[0004]

[Problems to be solved by the device]

 However, in the cab tilt pump device as described above, when performing the cab tilt manually, it is necessary to prepare a tool 7 such as a driver. If the tool 7 is not provided, the cab tilt cannot be performed. Had.

In view of the above situation, the present invention intends to provide a cab tilt pump device capable of performing a cab tilt manually without preparing a tool such as a driver.

[0006]

[Means for Solving the Problems]

 According to the present invention, a drive rod for manual operation of the tilt pump body is connected to a required position on one end side of an extendable lever whose one end is pivotally supported by the tilt pump body, and the tilt pump body is contracted. It is characterized in that a locking tool for fixing and holding a required position on the other end side of the lever to the tilt pump body is attached.

[0007]

[Action]

 Therefore, in the unlikely event that the drive motor of the tilt pump body breaks down, after releasing the lever that is fixedly held on the tilt pump body by the locking tool from the locking tool in the contracted state, When the lever is extended, the lever is reciprocated up and down with the pivot point of the tilt pump body as the fulcrum, and when the drive rod for manual operation of the tilt pump body is driven, the tilt pump body operates and the cab tilt is released. Done.

After the manual cab tilt is finished, the lever is fixedly held on the tilt pump body by engaging the lever with the locking tool while the lever is contracted.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of the present invention. In the drawings, the parts denoted by the same reference numerals as those in FIG. 4 represent the same parts, and the basic structure is shown in FIG. Although it is similar to the conventional one, the feature of the present embodiment is that, as shown in FIGS. 1 to 3, the tilting pump main body 1 is provided with a drive rod 3 for manual operation and one end thereof is a bracket of the tilting pump main body 1. 5 connects the required position on one end side of the expandable lever 8 pivotally supported on the shaft 11 with the shaft 12, and connects the required position on the other end side of the lever 8 in the contracted state to the tilt pump body 1. The point is that a locking tool 9 for fixing and holding the tilt pump body 1 is attached.

The lever 8 is formed by connecting a plurality of tubes 8a whose diameters are changed stepwise in a telescopic manner. A screw (not shown) is provided on the outer side of the connecting portion of each tube 8a. Further, the lock nut 10 screwed to the screw is provided, and the lever 8 can be expanded and contracted with the lock nuts 10 loosened. By tightening the lock nuts 10, the lever 8 is contracted as shown in FIG. Or in an extended state as shown in FIG.

Further, as shown in FIG. 2, the engaging member 9 is composed of a leaf spring having an open upper surface and curved portions 9a formed on both left and right sides which substantially match the outer diameter of the lever 8 and is contracted. By pressing the lever 8 in the closed state against the open end of the locking tool 9, the elasticity of the locking tool 9 expands the open end, and by further pressing down the lever 8, the lever 8 moves to the curved portion 9a. It is settled and fixedly held by the tilt pump body 1, and when the lever 8 is used, the lever 8 is pushed up so that the lever 8 can be easily disengaged from the locking tool 9.

With the configuration as described above, if the drive motor 2 should fail, the lever 8 fixed to the tilt pump body 1 is pushed up by the locking device 9 in the contracted state. When the lock nuts 10 are loosened, the levers 8 are extended and then the lock nuts 10 are tightened, the levers 8 are held in the extended state as shown in FIG. When the lever 8 is reciprocally moved up and down about a shaft 11 which is a pivot point with respect to the bracket 5, and the drive rod 3 for manual operation of the tilt pump body 1 is driven, the tilt pump body 1 is actuated and a cab tilt is performed. .

After the manual cab tilt is finished, from the state shown in FIG. 3, each lock nut 10 is loosened, the lever 8 is contracted, and then each lock nut 10 is tightened. As shown in the drawing, when the lever 8 is held in the contracted state and is pressed against the open end of the locking tool 9 in this state, the locking tool 9 expands the open end by its elasticity, and further lowers the lever 8 to move the lever 8 downward. 8 is accommodated in the curved portion 9a and is fixedly held by the tilt pump body 1.

Thus, the cab tilt can be performed manually without preparing a tool such as a driver.

The cab tilt pump device of the present invention is not limited to the above-mentioned embodiment, and various modifications can be made without departing from the scope of the present invention.

[0017]

[Effect of device]

 As described above, according to the cab tilt pump device of the present invention, the cab tilt pump device of the present invention has an excellent effect that the cab tilt can be manually performed without preparing a tool such as a driver.
