Abstract

An electric bolt lock gun comprises a gun body, a driving unit, a pull rod, a control unit, and a trigger. The gun body is composed of two half-sectioned housings each extended with a grip, wherein the two half-sectioned housings together form a muzzle along an axis, a front chamber, a rear chamber and a rear through hole. The driving unit includes a driving outer sleeve body having an electromagnetic coil and a magnetic movable inner sleeve body having one end provided with a reset retaining part and sheathed with a reset elastic member and an opposite end fit into the driving outer sleeve body, and is mounted in the rear chamber by the driving outer sleeve body. The pull rod has a stepped end portion having two steps of different diameters, in which an external threaded segment formed at a front end of the small diameter segment extends through the rear through hole into the gun body to pass through the driving outer sleeve body and project beyond the muzzle. The control unit is provided with a power cord and a power supply control wire that is connected to the driving unit for discharging of accumulated electricity and comprises a controller that is mounted in the grip to face outwards. The trigger is pivoted to the gun body to correspond to a front side of the controller. With this configuration, the external threaded segment of the front end of the pull rod that is driven by electrical power can be set in engagement with an inner thread of a bolt to conduct a forcible expansion operation in order to greatly increase working efficiency in usage.

Description

Electric anchor locking gun

The invention relates to an electric anchor bolt locking gun; in particular to an externally threaded rod front end threaded by an electric power, which is directly screwed with the inner end of the anchor bolt to perform a tensioning operation, thereby greatly improving the working efficiency in use, and Avoid the troublesome assembly of the rivet in the anchor bolt, simplify the structure of the anchor bolt, reduce the cost and shorten the delivery period, and innovate the inventor of the electric anchor bolt locking gun with multiple use progress.

According to Announcement No. 234973, and applying for the new patent application of "Gecko Gun Structure Improvement" No. 82211361, as described in paragraph 4 of page 5 of the specification, the corresponding operation of the cross-sectional embodiment diagram of the third figure: the above structure The gecko nail 1 is placed in the nail base 41, and the shifting piece 22 is driven by the front and rear displacement of the handle 20 to cause the dialing seat 21 to tilt up and down to catch the transmission rod 40 during the first displacement. When the second piece is displaced, the dialing piece 21 and the dialing piece simultaneously catch the transmission rod 40, so that the transmission rod 40 has three points of force, and the transmission rod 40 is driven to be displaced backward, and the plate base 30 thereof The transmission rod 40 is prevented from being displaced backward when the gecko nail 1 advances inward. When the transmission rod 40 drives the gecko nail 1 to be displaced backward, the stop piece 50 blocks the gecko screw seat 2 from moving forward, and the tail end of the gecko screw seat 2 is urged. 2A is pressed forward to a certain point, so that the gecko screw seat 2 is fixed on the wall, and then the plate machine 31 is buckled so that the objects are actuated by the springs s1, s2, and s3 to release the transmission rod 40, so that the transmission rod 40 is restored. To the original location.

For the operation as described above, first make a hole with the depth equivalent to the anchor bolt (Gecko screw base 2) on the installed wall surface, and then place the anchor bolt (Gecko screw seat 2) at the end end (reference number 2A). The thread is screwed with an externally threaded rivet (Gecko nail 1) and placed in the wall hole, and then the rivet (Gecko nail 1) is placed in the nail seat 41 of the Gecko gun of the cited case, and the handle 20 is displaced forward and backward. The dialing piece 22 drives the transmission rod 40 to be displaced rearward, so that the anchor claw protrudes to fix the gecko in the wall hole and then the rivet (gecko nail 1) is withdrawn, and the anchor bolt (gecko screw seat 2) is left in the A variety of different fixed uses are available on the walls.

The new patent structure of "Gecko Gun Structure Improvement" in the above-mentioned announcement No. 234973 can only be used in manual operation, which is not only slow in operation but also inferior in work efficiency, which is one of its disadvantages.

Furthermore, as in the previous structural operation combination of the previous case, as shown in the first figure, the inside of the anchor 2 (ie, the Gecko screw seat) must be pre-threaded with a pull stud 1 (ie, the gecko nail is cited) ), the head of the rivet 1 (ie, the gecko nail) can be pulled relative to the nail seat of a walled gun, so that the anchor 2 (ie, the gecko screw seat) is in the wall hole. An operator who can be forced by a gecko gun. This will cause the manufacturer of the anchor bolt 2 (ie, the Gecko screw seat) currently on the market to be screwed with a gecko gun in each anchor bolt 2 (ie, the Gecko screw seat). The operation of the pull stud 1 (ie, the cited gecko nail) will affect the delivery period due to the extension of working hours, which is the second disadvantage.

Finally, in each anchor bolt 2 (ie, the Gecko screw seat in the citation), a rivet 1 (ie, the gecko nail) that cooperates with the gecko gun is required to be screwed, and the rivet 1 will be added. The cost of the preparation of the wall nails does not match the cost of assembly work. Economic efficiency is the third of its shortcomings.

Therefore, how to solve the current general anchor bolt structure is limited by the use of the gecko gun must be assembled to pull the nail to extend the working hours, and affect the delivery schedule control and increase the working hours, the cost of preparation, and can only provide manual operation The inventors who have made many inconveniences, such as slow speed and inefficient efficiency, are the difficult points to be solved in this case.
