Technical Field
The utility model relates to a construction technical field, specifically speaking relates to a telescopic screw binding.
Background
Roof is often hugged closely in the installation of indoor roof cable testing bridge, because indoor roof is generally higher, execute the installation and the reinforcement that the staff only relied on self height can't carry out the crane span structure, often install with the help of ascending tools such as ladder or stool, when carrying out crane span structure jib screw fastening with the help of ladder or stool, every screw that has fastened just need remove stool or ladder, carry out the fastening of next jib screw again, this kind of method need frequently remove stool or ladder, construction speed is slow, constructor is under construction with the help of stool or ladder ascending a height, still can have certain danger of dropping.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model provides a telescopic screw binding, including the sleeve, vice pole and the mobile jib that connect gradually, just vice pole and mobile jib cup joint, are provided with a plurality of regulation holes along the axial interval on the vice pole, are provided with at least one regulation hole on the mobile jib, and vice pole and mobile jib are connected to the fitting pin through the regulation hole of screw in vice pole and mobile jib to realize the regulation of binding length, the sleeve is used for fastening or dismantling the space top screw.
Optionally, an operating rod is further vertically connected to an end of the main rod opposite to the auxiliary rod.
Optionally, the length of the secondary rod is 1.5m-2.5m.
Optionally, the main rod has a length of 1.5m-2.5m.
Optionally, the sleeve is a hexagonal sleeve.
Optionally, a base is further provided, a through hole is provided on the base, and the lower end of the main rod passes through the through hole, so that the operating rod is arranged on the upper surface of the base.
Optionally, a plurality of balls are embedded in the upper surface of the base, and the operating rod is arranged on the balls.
Optionally, the bottom of the base is provided with rollers.
Compared with the fastening and the disassembly of screws on the top of the space by adopting a climbing tool in the past, the telescopic screw fastener has the advantages that the length is adjustable, the screws on the top of the space can be conveniently fastened or disassembled, the fastener is convenient to take materials, the manufacturing cost is low, and the telescopic screw fastener is manufactured in one step and can be recycled and used permanently. Meanwhile, potential safety hazards are reduced, and the construction efficiency is greatly improved.
Drawings
The above features and technical advantages of the present invention will become more apparent and readily appreciated from the following description of the embodiments thereof, taken in conjunction with the accompanying drawings.
FIG. 1 is a schematic view illustrating a retractable screw fastener according to an embodiment of the present invention;
fig. 2 is a schematic view showing a retractable screw fastener with a base according to an embodiment of the present invention.
Detailed Description
The embodiments of the present invention will be described below with reference to the accompanying drawings. Those of ordinary skill in the art will recognize that the described embodiments can be modified in various different ways, or combinations thereof, without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Furthermore, in the present description, the drawings are not drawn to scale and like reference numerals designate like parts.
The telescopic screw fastener of the present embodiment includes a sleeve 1, a sub-rod 2, a main rod 3, and an operating rod 4.
The auxiliary rod 2 can be made of a steel pipe with the length of DN25mm multiplied by 2mm, the other end of the auxiliary rod 2 is connected with one end of the main rod 3, and the auxiliary rod 2 is provided with an adjusting hole 21 along the axial direction every 100mm, for example. The length of the auxiliary rod 2 can be selected according to actual needs, and is generally 1.5m-2.5m.
The mobile jib 3 can adopt DN30mm 2mm steel pipe, and the other end of mobile jib 3 welds with DN20mm 2mm 200 mm's action bars 4, is provided with an adjustment hole 21 on the mobile jib 3, aligns through the arbitrary regulation hole position with auxiliary rod 2 to link together auxiliary rod 2 and mobile jib 3 through fastening pin or bolt etc. thereby realize using the regulation of length. The length of the main rod can be selected according to actual needs, and is preferably 1.5m-2.5m.
The operating rod 4 is made of a steel pipe with the length of 200mm, and the operating rod 4 is vertically welded with the main rod 3 and used for applying rotating force.
Further, a base 5 is further provided, a through hole is provided on the base 5, and the lower end of the main rod 3 passes through the through hole, so that the operating rod 4 abuts against the upper surface of the base 5. This makes it possible to secure the screw without manually lifting the main bar. In order to make the operation rod 4 rotate smoothly, a plurality of balls 51 can be embedded on the upper surface of the base 5, and the operation rod 4 rotates on the balls without labor. In addition, rollers 52 may be provided on the bottom of the base 5 to facilitate pushing into place.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
