Embodiment Construction

[0041] refer to figure 1 , an installation device for municipal buildings, comprising an upper cylinder 10 connected vertically, a lower cylinder 20 and a transmission assembly a connected up and down.

[0042] refer to figure 1 , a guide rod 30 is movably inserted in the upper cylinder body 10, and the bottom end of the guide rod is provided with a tip 31 cooperating with the screw head of the grub screw. Evenly distributed through holes 41, grub screws are installed in the through holes, the center line of the through holes is parallel to the centerline of the guide rod, the distance between the through holes and the rotating drum shaft is equal to the distance between the guide rod and the rotating drum rotating shaft 42.

[0043] The upper cylinder 10 includes an outer cylinder 11 and an inner cylinder 12, and the outer cylinder and the inner cylinder are connected by a connecting plate 13 between the outer cylinder and the inner cylinder. A vertical slider chute is prov...

Abstract

The invention discloses installation equipment used for civic buildings. The installation equipment comprises an upper barrel and a lower barrel. A guide rod capable of rising, falling and rotating is movably inserted into the upper barrel. A rotating drum is mounted in the lower barrel and provided with a plurality of through holes distributed in the circumferential direction. A rotating shaft of the rotating drum is parallel to the guide rod. The guide rod is aligned with the through hole located under the guide rod in an up-down manner. The through holes are used for accommodating flat head screws. The bottom end of the guide rod is provided with a pointed portion matched with the flat head screws. When the equipment is used, an electric head of an electric tool is in embedded fit with the top of the guide rod, the guide rod is pressed downwards, and the electric head drives the guide rod to rotate to enable the bottom of the guide rod to be in embedded fit with the screw head of one flat head screw; and then the lower end of the lower barrel is placed to a position needing screw fastening, and the electric head is continued to be pressed downwards until the lower end of one flat head screw makes contact with a wood board. After the flat head screw in one through hole is used, the rotating drum enables the next through hole to be aligned with the guide rod in an up-down manner, and thus, efficient and continuous operation is conducted conveniently.

Description

technical field [0001] The invention belongs to the field of municipal buildings, and in particular relates to installation equipment for municipal buildings. Background technique [0002] Prior art In the operation of municipal construction projects, it is often necessary to use a screwdriver to screw flat-head screws into wooden boards. Due to the instability of manual work, the screws are often twisted crookedly, making the fastening effect unsatisfactory. [0003] The invention patent application with the application number 201610496210.3 discloses a municipal building installation tool, which includes an upper cylinder and a lower cylinder arranged coaxially. A liftable and rotatable guide rod is inserted in the upper cylinder, and a guide rod is installed in the lower cylinder. There is a rotating drum, on which a number of through holes distributed along the circumference are opened, the rotation axis of the rotating drum is parallel to the guide rod, and the guide ro...
