Description

Technical Field

[0001] The utility model relates to the field of hole openers, in particular to a hole opener for fire fighting construction. Background Art

[0002] A fire hole opener is a tool used by electricians to open holes in thin steel plates. When installed on an ordinary electric drill, the hole opener can easily cut round holes, square holes, triangular holes, straight lines and curves on the planes of various plates such as copper, iron, stainless steel and plexiglass. It is flexible, convenient and safe, and has a wide range of uses in fire protection construction.

[0003] For different hole-opening objects, some are regular objects, some are irregular objects, some are flat, and some are curved, etc., the existing hole openers cannot handle the hole-opening objects well and flexibly drill and locate them. Each hole-opening position positioning often takes a lot of time, which reduces work efficiency. For this reason, we propose a hole opener for fire-fighting construction. Utility Model Content

[0026] Furthermore, a hollow connecting rod is provided at one end of the main frame 1 corresponding to the main shaft 6, and a thread three 18 and a thread two 8 are respectively machined inside and outside the hollow connecting rod. A rectangular plate surface with connecting rods 2 19 on all four sides is provided at the end of the main frame 1 away from the main shaft 6, and support rods are provided at the four corners of the end of the rectangular plate surface away from the main shaft 6. Two connecting rods three 20 axially symmetrically distributed are welded between the two support rods. The two connecting rods three 20 are mainly used to cooperate with external ropes to bind large objects or large irregular objects, so as to achieve the positioning effect of the hole opener, ensure the hole opening accuracy of the objects to be opened, and improve work efficiency.

[0027] Furthermore, the ray intersection adjustment device consists of a connecting plate 4, an adjustment sleeve 5, four intermediate rods 3 and four laser emitters 2. The intermediate rod 3 is a cylindrical connecting rod with connecting holes at both ends. The main adjustment power of the ray intersection adjustment device comes from the staff rotating the adjustment sleeve 5, and the adjustment sleeve 5 drives the connecting plate 4 to move vertically axially, and the adjustment sleeve 5 and the connecting plate 4 are connected and rotatable with a normal gap. The angle of the laser emitter is adjusted by the intermediate rod 3 to face various open-hole objects.

A handle is provided on the end of the adjusting sleeve 5 away from the matching groove 23, and a thread four 24 is machined on the axially symmetrical center line of the adjusting sleeve 5 to cooperate with the thread two 8.

[0029] Furthermore, the connecting plate 4 as a whole is a rectangular plate surface with a center opening for mating connection with the mating groove 23. Four connecting rods 21 axially symmetrically distributed are provided at the midpoints of the four sides of the connecting plate 4.

[0031] Working principle: Assemble the hole opener for firefighting construction correctly according to the diagram, place the object to be drilled at the bottom of the main frame 1, that is, between the two connecting rods 3 20. If the object is too large, use a rope to wrap it around the two connecting rods 3 20 and fix it. Rotate the adjusting sleeve 5 with the threaded fit on the main frame 1. The adjusting sleeve 5 drives the connecting plate 4 to start vertical axial movement, thereby changing the intersection position of the rays emitted by the four laser emitters 2 through the intermediate rod 3 to cope with different objects to be drilled. By adjusting the adjusting sleeve 5, the intersection point of the rays is hit at the center point of the hole to be drilled of the object to be drilled, and start the motor 13. The output shaft of the motor 13 drives the drill bit 12 to rotate at high speed. At this time, the operator rotates the main shaft 6. The main shaft 6 and the top of the motor 13 are rotatably connected, so that the guide slider 14 of the motor 13 cooperates with the slide groove 17 of the main frame 1 and starts to move slowly downward until the hole is successfully drilled.
