Based on this, it is particularly necessary to design a new type of construction machinery instrument. Content of the Utility Model

[0003] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a construction machinery instrument, which has a simple structure, reasonable design, high strength, high installation versatility, long service life, strong practicality, and is easy to promote and use.

[0004] In order to achieve the above purpose, the utility model is realized through the following technical solutions: a construction machinery instrument, including a touch display screen, an upper bracket, a PCB board, a rear cover, a USB interface, a connector, and a lid. The touch display screen is installed on the surface of the upper bracket. The upper bracket and the rear cover are fixedly connected by M4 screws to form the housing of the instrument. The PCB board is installed inside the housing and is fixed on the upper bracket by M4 screws. The USB interface and the connector are installed on the PCB board. The USB interface is located at the bottom end of the PCB board, and the connector is located above the USB interface. Installation positions corresponding to the USB interface and the connector are provided on the rear cover, and a lid is installed on the rear cover.

[0012] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] Referring to Figures 1-3 , the following technical solutions are adopted in this specific embodiment: An engineering machinery instrument includes a touch display screen 1, an upper bracket 2, a PCB board 3, a rear cover 4, a USB interface 5, a connector 6 and a lid 7. The touch display screen 1 is installed on the surface of the upper bracket 2. The upper bracket 2 and the rear cover 4 are fixedly connected by M4 screws 8 to form the housing of the instrument. The PCB board 3 is installed inside the housing. The PCB board 3 is fixed on the upper bracket 2 by M4 screws 8. A USB interface 5 and a connector 6 are installed on the PCB board 3. The USB interface 5 is located at the bottom end of the PCB board 3, and the connector 6 is located above the USB interface 5. Installation positions corresponding to the USB interface 5 and the connector 6 are provided on the rear cover 4, and a lid 7 is installed on the rear cover 4.
