The present invention relates to a manual perforator for water fountain construction that is used to easily connect a new water fountain pipe without interrupting the water flowing into the main water supply pipe when connecting a new water fountain pipe in an already installed water supply water pipe. Forming the lifting screw tube so that it can be raised and lowered therein, and drilled by attaching a drill drill at the bottom of the lifting screw tube to enable more convenient and safe drilling work.

This will be described in more detail as follows.

The fixed outer cylinder 1, which maintains a predetermined length, becomes a cylindrical body, and the upper threaded portion 2a of the connector 2 is screwed to the lower threaded portion la, and the connecting screw tube 2b is protruded at the lower end of the connector 2. The inside of the fixed outer cylinder (1) has a rotary tube (4), but the upper support (4c) is penetrated into the center hole of the fixed outer cylinder (1) while the square projection (4b) is vertically exposed to expose the square projection (4b) 1) to the one-way gear (5) and to terminate the elevating screw pipe 11 to the connector (2) center hole (2) from the inside of the rotary tube, but the key groove (11a) and the rotary tube of the elevating screw pipe outer surface ( 4) Connect the key pieces 12 between the inner groove key grooves 4a of the inner part, and attach the drill drill 13 to the lower thread portion of the elevating screw tube 11 so that the lower portion is exposed to the bottom of the connector so that the elevating screw tube Insert the central threaded rod 14 into the central threaded hole (11) of (1), but the supporting portion 14a of the central threaded hole 14 is supported by the rotary tube center hole (4). While protruding upward and connected to the handle 15, the rotor (6) is covered on the outer periphery of the one-side gear (5), but the guide projection hole (7) is drilled in the one-side protruding pipe (6a), and the locking protrusion (8a) is located inside. And a contact hole 8 with a spring in the spring 9 so that the locking projection 8a is in contact with the toothed projection 5a of the one-way gear, and the handle 10 is attached to the protruding tube outer end. to be.

The present invention as described above is a water fountain installed in the coupling band 18 for the fountain work, the connection screw pipe (2b) of the connecting car (2) attached to the lower end of the fixed outer cylinder (1) newly installed on the outer surface of the main water supply pipe (17) It is attached to the screwed portion (19a) of (19) and fixed to the major part, and then by pressing the handle 15 lightly with one hand and manually reciprocating the handle 10 in the range of about 90 degrees with the other hand, Since the electron 6 rotates the one-way gear 5 clockwise, the rotary tube 4 connected to the square center hole rotates along. The elevating screw tube 11 connected to the rotary tube 4 and the key piece 12 is driven, wherein. The elevating screw tube 11 is screwed to the central threaded hole 14 and acts to descend like a driven operation, so that the drilling drill 13 installed at the lower end of the drilled hole drills the perforated part. , After drilling, the handle 15 is rotated to reverse the center screw hole 14, thereby elevating the elevating screw pipe 11.

In this way, it is possible to easily drill, but the elevating screw tube 11 which is elevated to the center hole (2) of the connector 2 in the rotary tube installed in the fixed outer cylinder 1 has a misalignment packing (in the outer periphery of the lower entrance). 3) There is no fear of water entering inside because it is waterproof even when the water contacting the lower end, the lowering operation during the drilling operation is operated by the handle 10, the restoration operation is the center with the handle 15 It is achieved by the screw rod (14), so it is not only quick during the work but also the lifting operation is performed inside the fixed outer cylinder (1), so that the lifting screw pipe (11) is concealed and filled with grease oil to oxidize the inside. Can be prevented, the operation can be made flexible, there is almost no risk of failure, and the lifting screw tube 11 is lowered by turning the handle 10 in a state where the fixed outer cylinder 1 is attached to the cold air. city Will have utility that you can use to pay less because they're easy to carry the advantage of being able to apply a large force to the perforation drill manual, yet superior functionality, as well as to be easily dismantled after drilling because.

Claims (1)

The fixed outer cylinder 1, which maintains a predetermined length, becomes a cylindrical body to allow the upper threaded portion 2a of the connector 2 to be screwed to the lower threaded portion 1a, and the connecting screw tube 2b is protruded from the lower end of the connector 2. The inside of the fixed outer cylinder (1) has a rotary tube (4) inside the upper support portion (4c) penetrating through the fixed hole (1) center hole while the square projection (4b) is vertically exposed to the vertical projection ( 4b) is connected to the one-way gear (5), and the lifting screw tube 11 is terminated to connect the connector (2) center hole (2) inside the rotary tube, but the key groove (1la) and the rotary tube on the outer surface of the lifting screw tube The key piece 12 is connected between the inner groove key grooves 4a of (4), and a drill drill 13 is attached to the lower thread portion of the elevating screw tube l1 so that the lower portion is exposed to the bottom of the connector. Insert the central threaded rod (14) into the central threaded hole (11-ga) of the tuber (1), but the supporting portion (14a) of the central threaded rod (14) is supported by the rotary tube centered hole (4-ga). As it protrudes upward, it is connected to the handle 15 and covers the rotor 6 on the outer periphery of the one-way gear 5, but drills the guide transverse hole 7 in the one-side protruding pipe 6a, and then engages the protrusion 8a inside. In which the contact hole 8 with the spring is elastically embedded in the spring 9 so that the locking projection 8a is in contact with the toothed projection 5a of the one-way gear, and the handle 10 is attached to the outer side of the protruding pipe. Manual perforator for construction.
