Abstract
A kind of chain wheel sleeve reinforcing bar connector, including sprocket wheel screw shell and chain；Sprocket wheel screw shell includes head internal screw thread, tail portion internal screw thread, sprocket ring and whelp；Reinforcing bar one is connect with the head of screw shell with screw thread pair, and reinforcing bar two is connect with the tail portion of screw shell with screw thread pair；Chain is set on the outside of sprocket ring, affects chain, and sprocket wheel screw shell gradually rotates, and realizes the installation or removal of sprocket wheel screw shell.Present invention efficiently solves the problems that screw shell disassembling operations space is larger, realize screw shell in the installation and removal in small space or hidden region.
Description
Technical field
The present invention relates to rebar connecting technology field, in particular to a kind of chain wheel sleeve reinforcing bar connector.
Background technique
Screw shell is that reinforcing bar connects one of most common mode, but the installation and removal restrictive condition of screw shell compared with
More, common wrench, there are the requirement of a minimum rotation angle, works as threaded connecting sleeve when mounting and dismounting threaded coupling sleeve
Common wrench just can not be applicable in when cylinder is located at deeper narrow space, buried depth or hidden region；Box spanner, right-angle wrench are only capable of
Apply torsion after being inserted on screw element axis direction, it is then helpless for the threaded coupling sleeve for connecting two reinforcing bars.
When screw shell is connected for the reinforcing bar between concrete prefabricated element, to guarantee the close of seam docking, warp
It often needs to provide the pretightning force of reinforcing bar, in the actual construction process, anti-spiral shell using the acting on drawing of reverse thread rotation in sleeve
The reinforcing bar pretightning force numerical value that line provides drawing is difficult to control relatively coarse.
Summary of the invention
In view of the above drawbacks of the prior art, the present invention provides a kind of chain wheel sleeve reinforcing bar connector, realizes minimum sky
Between and hidden region screw shell connector installation and removal, while realizing pre- between two reinforcing bars of screw shell connection
The accurate control of clamp force.
To achieve the above object, the invention discloses a kind of chain wheel sleeve reinforcing bar connectors, include at least one sprocket wheel spiral shell
Line sleeve and a chain；The sprocket wheel screw shell includes head internal screw thread, tail portion internal screw thread, sprocket ring and whelp；Institute
State reinforcing bar one end setting external screw thread, the head internal screw thread phase of the end external screw thread of the reinforcing bar one and the sprocket wheel screw shell
It matches and connects, external screw thread, the end external screw thread of the reinforcing bar two and the sprocket wheel thread bush is arranged in the end of the reinforcing bar two
The tail portion internal screw thread of cylinder matches and connects；The chain is set on the outside of the sprocket ring.
Preferably, the chain is driving chain, and the pin shaft spacing of the chain and the spacing of the whelp match,
The chain is affected, the sprocket wheel screw shell gradually rotates, and realizes the installation or removal of the sprocket wheel screw shell.
Preferably, the head internal screw thread of the sprocket wheel screw shell and the hand of spiral and screw pitch of tail portion internal screw thread are identical；
The sprocket wheel screw shell is installed in advance on reinforcing bar one or reinforcing bar two, after reinforcing bar one and reinforcing bar two are aligned, affects the chain
Item, gradually second reinforcing bar is stretched out and is screwed into rotation to the sprocket wheel screw shell from a reinforcing bar, realizes connection.
Further technical solution is, the head internal screw thread of the sprocket wheel screw shell and the tail portion internal screw thread
Hand of spiral is opposite；After the completion of the reinforcing bar one and the reinforcing bar two are connected, the chain, opposite hand of spiral are affected
So that two reinforcing bars gradually tense in opposite directions, realize that the preferably preload of docking reinforcing bar acts on.
Further technical solution is, the head internal screw thread of the sprocket wheel screw shell and tail portion internal screw thread it is described
Hand of spiral is identical, screw pitch is different；After the completion of the reinforcing bar one and the reinforcing bar two are connected, the chain is affected, it is different
Screw pitch two reinforcing bars are gradually tensed in opposite directions, realize docking reinforcing bar preload act on and reach connects reinforcing bar between pretightning force
The purpose accurately controlled.
Preferably, the end external screw thread of the head internal screw thread of the sprocket wheel screw shell and the reinforcing bar one it
Between, between the tail portion internal screw thread of the sprocket wheel screw shell and the end external screw thread of the reinforcing bar two lubricant is set, subtract
The frictional resistance of minor thread rotation.
The present invention has below beneficial to benefit.
Present invention efficiently solves the problems that the operating space of screw shell dismounting is larger, realize screw shell narrow
The installation and removal in small space or hidden region；And realize screw shell connection two reinforcing bars between pretightning force it is accurate
Control.

Attached drawing 2: chain wheel sleeve reinforcing bar connector assembling figure.
Specific embodiment
Embodiment.
As depicted in figs. 1 and 2, a specific embodiment of the invention includes a sprocket wheel screw shell 1 and a transmission chain
Item 2；Sprocket wheel screw shell 1 includes head internal screw thread 101, tail portion internal screw thread 102, sprocket ring 103 and whelp 104, sprocket wheel spiral shell
The head internal screw thread 101 of line sleeve 1 and the hand of spiral and screw pitch of tail portion internal screw thread 102 are identical；Outer spiral shell is arranged in one 3 end of reinforcing bar
Line 301, the end external screw thread 301 of reinforcing bar 1 match and connect with the head internal screw thread 101 of sprocket wheel screw shell 1, reinforcing bar two
External screw thread 401,102 phase of tail portion internal screw thread of the end external screw thread 401 and sprocket wheel screw shell 1 of reinforcing bar 24 is arranged in 4 end
Match and connects；Driving chain 2 is set to 103 outside of sprocket ring, and driving chain 2 includes pin shaft 201, carrier bar 202, sleeve and rolling
Column, 201 spacing of pin shaft of driving chain 2 and the spacing of whelp 104 match.
Between the head internal screw thread 101 of sprocket wheel screw shell 1 and the end external screw thread 301 of reinforcing bar 1, sprocket wheel screw shell
