Description
Technical field
The present invention relates to tube expander field, more particularly, to a kind of tube expander shown and limit expander amount.
Background technology
Many plastic conduits, as the pipelines such as PE-X, PE-RT, PB have good memory ability, i.e. at port by spreading
After, can substantially be contracted to original size after the regular hour, sliding tight type pipe fitting make use of this memory effect of tubing just
Fit sealing should be realized.In the installation process of sliding tight type pipe fitting, first use expanding tool will have the tubing of memory effect
Port opens, and is then inserted by sliding tight type pipe fitting rapidly in the tubing of enlarging, after tube opening shrinks, with sliding clamping tool
Cutting ferrule is advanced and slips into compression tubing so that sliding tight type pipe fitting is integrated into one with tubing.Plastic conduit in expanding procedure, for
Avoid that expander amount is excessive to be damaged tubing, need several times and be gradually increased expander amount to carry out expander.If there is no expander
Amount accurately display, only is difficult to hold each expander amount with sensation, it is easy to damage tubing, thus affects connection effect.And, no
The ability of same its memory effect of tubing has bigger difference, and therefore its maximum expander amount is the most different.For solving this problem,
Tube expander is configured with the adaptive different tubing of different expander heads at present, causes expander head specifications and models more, adds instrument
Cost；Meanwhile, need to often change different expander heads, increase installation workload, reduce installation effectiveness.
Existing tube expander many employings hinge arrangement, manual or hydraulic-driven, its advantage is that radial direction expander amount is big,
Shortcoming is cannot accurately to know each expander amount.Owing to existing tube expander expander amount is relatively big, at plastic conduit in expanding procedure,
For avoiding tubing is damaged, need several times and be gradually increased expander amount to carry out expander, owing to there is no expander amount indication mechanism,
Each expander amount can only be held with sensation, it is easy to damage tubing, thus affect connection effect.Another shortcoming is, is expanding not
With plastic tube time need to be equipped with different expander heads, cause expander head specifications and models more, add the cost of instrument；Meanwhile,
Need to often change different expander heads, increase installation workload, reduce installation effectiveness.
Summary of the invention
The present invention is directed to the deficiency of existing product, it is provided that a kind of tube expander shown and limit expander amount, this tube expander
Installation personnel can be allowed accurately to hold each expander amount, it is to avoid expander amount is excessive to be damaged tubing；Can limit the most simultaneously
Big expander amount, can be used for the enlarging of different tubing, reduces the kind of expander head, improve installation effectiveness.
For solving above-mentioned technical problem, technical scheme is as follows:
A kind of tube expander shown and limit expander amount, including fixed handle, flexible handle and cone, described fixed handle and
Flexible handle passes through pin and rod hinge connection, and fixed handle is provided with a hole, location, and described cone passes this hole, location, cone one
End is connected with flexible handle by pin, and the other end is free end, by, in applying external force to flexible handle, changing activity
The angle of handle and fixed handle, thus band movable cone hole, location spacing under do movable；Described tube expander also includes
Expander amount indication mechanism, described expander amount indication mechanism includes the tooth that the tooth bar that is arranged in cone is mutually ratcheting with described tooth bar
Travelling gear that bar gear is mutually ratcheting with described rack pinion and the display dial being in transmission connection with described travelling gear, institute
State display dial and be provided with the first pointer for showing expander amount.
When, in cone moving process, its amount of movement is converted on display dial by tooth bar by rack pinion and travelling gear
The rotation of the first pointer, owing to cone amount of movement and expander amount are proportionate relationship, therefore by observing display dial the first pointer
Indicated scale i.e. may know that expander amount.
In the preferred scheme of one, described pyramid side is provided with the first inclined-plane, and described tube expander also includes expander amount
Limiting mechanism, described expander amount limits mechanism and includes spacer pin, the first bevel gear, the second bevel gear, spur gear and adjusting knob,
One end of described spacer pin is provided with the second inclined-plane matched with described first inclined-plane, and spacer pin is entered by fixed handle locating surface
Row location, can only move up and down, and spacer pin and the first bevel gear are threaded connection, the first bevel gear and the second bevel gear phase
Ratcheting, described adjusting knob and the second bevel gear are connected by same axle, and adjusting knob is connected by gear drive with spur gear,
Spur gear is also in transmission connection with display dial, and described display dial is provided with the second pointer for showing maximum expander amount.
Spacer pin and the first bevel gear are threaded connection, and therefore having self-locking property, i.e. spacer pin will not be because of being subject to
Axial force and change position.By adjusting knob, on the one hand drive spur gear to rotate, thus drive the second pointer on display dial
Rotate, maximum expander amount can be set by observing the second pointer indication scale；On the other hand the second bevel gear is driven to rotate, from
And driving the first bevel gear to rotate, the first bevel gear drives spacer pin to move up and down by helicitic texture, makes the second of spacer pin
Inclined-plane changes with the first chamfer distance of cone, thus limits the distance that cone moves forward, and then reaches to limit it
The purpose of big expander amount, can arbitrarily limit maximum expander amount, can be used for the enlarging of different tubing, reduce the kind of expander head
Class, improves installation effectiveness.
In the preferred scheme of one, the length of described second pointer and the first pointer is different, in order to distinguishes and expands in real time
Pipe amount and the instruction of the maximum expander amount of restriction.
In the preferred scheme of one, described second pointer be shorter in length than the first pointer.
In the preferred scheme of one, described fixed handle and flexible handle are equipped with Handheld Division, in order to operator
Hand-held.
Compared with prior art, technical solution of the present invention provides the benefit that: the open one of the present invention can show and limit
The tube expander of expander amount, described tube expander also includes that expander amount indication mechanism, described expander amount indication mechanism include being arranged on cone
Rack pinion that tooth bar on body is mutually ratcheting with described tooth bar and the mutually ratcheting travelling gear of described rack pinion and with institute
Stating the display dial that travelling gear is in transmission connection, described display dial is provided with the first pointer for showing expander amount.Work as cone
In moving process, its amount of movement is converted into the rotation of the first pointer on display dial by rack pinion and travelling gear by tooth bar
Turn, owing to cone amount of movement and expander amount are proportionate relationship, therefore by observing the scale indicated by display dial the first pointer
I.e. may know that expander amount, therefore can show expander amount in real time, installation personnel can be allowed accurately to hold each expander amount, it is to avoid once expand
Pipe amount is excessive to be damaged tubing.
