Description
Technical Field
The utility model relates to a fastener for the building engineering specifically is a quick fastener for jacking.
Background
In the building engineering, the scaffold is a working platform which is set up for ensuring the smooth proceeding of each construction process. The installation of the top support in the scaffold construction is an important process. At present, the installation of the jacking usually adopts a manual fastening mode.
However, practice shows that the existing installation mode of the manual fastening jacking has the following problems in use: firstly, the upper support (one type of top support) is high in height and small in arrangement distance, so that manual fastening operation is inconvenient; secondly, the jacking quantity in the scaffold is large, and manual fastening wastes time and labor.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the mounting means in use that current manual fastening top held in the palm and have the inconvenient, waste time and energy problem of operation, provide a quick fastener for supporting on the top.
The utility model discloses an adopt following technical scheme to realize:
a quick fastening device for a jacking comprises a vertically-arranged jacking, wherein the jacking comprises a screw rod and a nut which is connected to the screw rod in a threaded manner and is provided with a handle; the locking sleeve is fixedly sleeved on the nut, the locking sleeve is vertically and fixedly arranged above the locking sleeve, the mounting pipe is provided with an internal thread, an electric hand drill with a downward drill bit is arranged above the mounting pipe, an external thread is arranged on the side wall of the drill bit, and the drill bit of the electric hand drill is screwed in the mounting pipe.
During operation, at first start the electric hand drill, the drill bit rotates and drives the installation pipe syntropy and rotate, drives the locking sleeve syntropy and rotates then, and the rotation of locking sleeve drives the nut syntropy and rotates, and in the time of the pivoted, under the cooperation of the internal screw of nut and the external screw thread of lead screw, the nut is twisted to appointed height downwards soon to realize the purpose of quick fastening nut, overcome the current mounting means in use that manual fastening top held in the palm has the inconvenient, waste time and energy problem of operation.
The lower part cover of lead screw is located the below of nut and the longitudinal section is curved registration arm, and the radius of registration arm is less than the length of handle.
The positioning pipe can position the fastening position of the nut, so that the nut is conveniently installed to a specified height, and the installation precision of the fastening device is improved; the outside of lead screw can be located fast conveniently to the structural design of registration arm arc longitudinal section with the registration arm cover, has further increased this fastener's maneuverability.
The number of the handles is two, and the two handles are symmetrically arranged on two sides of the outer side wall of the nut; two grooves are symmetrically formed in the lower end of the locking sleeve, and the two handles are correspondingly clamped in the two grooves.
The structural design convenience of recess is with locking sleeve and nut fixed connection, and then is convenient for drive the nut and rotates, can prevent to take place relative rotation between the two, and the mode of joint is convenient installs and dismantles locking sleeve simultaneously, has effectively improved the efficiency of construction.
The upper end face of the locking sleeve is integrally provided with an upper end cover, and the mounting pipe is vertically fixed in the center of the upper end cover.
The structural design of upper end cover has increased the fastness of installation pipe with locking sleeve junction, and then has increased this fastener's life.
The utility model has the advantages of reasonable design reliably, realized the mesh of quick fastening nut, the simple operation has reduced the working strength in the construction moreover, has effectively improved the efficiency of construction, and the sound construction simultaneously, easy to assemble and dismantlement have that the structure is simple and easy, the practicality is strong, the installation accuracy is high, low in manufacturing cost, long service life's advantage, are applicable to the fastening operation that the top held in the palm in the scaffold frame construction.
