The double-clamping locking mechanism comprises a base and a pulling fastener connected with the base, the pulling fastener is an eccentric structure, a fixing post is disposed in the middle of the base, a press plate is sleeved on the fixing post, the eccentric pulling fastener is hinged at the end of the fixing post and disposed outside the press plate, at least two clamping grooves are arranged on the surface, which is opposite to the base, of the press plate, and the clamping grooves are symmetric relative to the fixing post. The at least two symmetric clamping grooves are disposed between the base and the press plate, pipes are clamped in the clamping grooves under action of the pulling fastener, and accordingly the double-clamping locking mechanism can simultaneously clamp the two pipes.
Description
Technical field
The utility model relates to a kind of locking mechanism, especially a kind of can be to the double fastener that two parts clamp tight locking mechanism.
Background technique
Locking mechanism is easy to use because of it, clamp and to loosen operation all very easy, and this body structure is also fairly simple, used widely in existing manufacturing industry, locking mechanism has a variety of forms, such as with bolt or screw lock, it is exactly with bolt the connecting sheet clamping tube to be formed locking that pipe in the picture construction industry connects, but this locking mechanism shows trouble slightly, operate with instrument, only uses handwheel locking under the less situation of clamping force.
A kind of off-centre that now commonly used is pull the tight mechanism of padlock, the rotation of pulling button by off-centre changes the locking length of screw rod or the angle of articulation of clamping, thereby produces clamping force, when not having external force, pull button and also can not automatically reply, can guarantee to pull the tight validity of clip.But this tight mechanism of padlock of pulling is used for clamping pipe fitting, thereby changes the parts clamping of the shape of pipe fitting with pipe fitting inside, and the extended length that perhaps shortens screw rod realizes clamping.
Patent Office of the People's Republic of China has announced a CN2544089Y patent on April 9th, 2003, name is called anticreep elevator pin, constitute by pin main body, axle sleeve, axle, back-up ring, pin, spring, lock ring, locking bar, ring, utilize wobbler action to produce moment of torsion, make lock ring fasten the elevator ear and be pressed on the pin main body and realize self-locking, utilize locking bar and elevator ear empty calorie extremely to realize double insurance simultaneously.But the pin configuration more complicated of this structure is assembled cumbersomely, and this pin can only realize being in the locking of the pipe fitting on the same line, can not be with two pipe fittings lockings that separate.
Summary of the invention
The purpose of this utility model provides the tight locking mechanism of a kind of double fastener, and once-through operation can clamp two pipe fittings simultaneously, and two pipe fittings are fixing simultaneously.
The utility model has solved the shortcoming that once can only clamp a pipe fitting in the prior art, and a kind of two pipe fittings that once can clamp are provided, and also has the function of unclamping automatically simultaneously.
The technological scheme that its technical problem that solves the utility model adopts is: the tight locking mechanism of a kind of double fastener, comprise base and the button of pulling that links to each other with base, pull button and be eccentric structure, the neutral position that it is characterized in that base is provided with fixing column, be equipped with pressing plate on the fixing column, the hinged off-centre in the end of fixing column is pulled button, and off-centre is pulled the outside that button is arranged on pressing plate, the face that pressing plate is relative with base is provided with clamping slot, at least two of clamping slots and with respect to the fixing column symmetry.Fixing column couples together pressing plate and base and forms a H shape structure, off-centre pulls that button is hinged on the fixing column end and in the outside of pressing plate, can change gap between pressing plate and the base when button is pulled in rotation like this, clamping slot between pressing plate and the base can be placed pipe fitting, when changing, the gap between pressing plate and the base just pipe fitting can be clamped or loosens, clamping slot is at least two, can clamp at least two pipe fittings simultaneously like this.
As preferably, the cross section of clamping slot is an arc, is provided with spring between base and the pressing plate.Clamping slot is the structure of arc, with can increase area of contact after pipe fitting contacts, the clamped back of pipe fitting just can not drop out like this, spring between base and the pressing plate can keep the gap between pressing plate and the base, thereby conveniently pipe fitting is snapped onto in the clamping slot, in that unclamp can also the self-relaxation clamping slot when pulling button, make things convenient for pipe fitting to deviate from.
As preferably, base and pressing plate are square, clamping slot totally two be parallel to each other, the center line of base and the center line of pressing plate are provided with projection, spring is nested with on projection, projection and fixing column are in the same line.Projection is set is used for fixing spring, rotation is pulled to withhold when contracting spring and can not deflected.
As preferably, the clamping slot that is provided with between pressing plate and the base is three, is triangularly arranged, and fixing column is in leg-of-mutton middle.This is another kind of scheme, and three clamping slots can clamp three pipe fittings, and rotation is pulled button and can be clamped simultaneously three pipe fittings.
As preferably, be fixed with inserts on the clamping slot of base and pressing plate, the shape of inserts and clamping slot matches.Inserts can increase the frictional force of clamping slot, and inserts can also be protected pipe fitting simultaneously, prevents that pipe fitting from causing surface breakdown after clamped.
As preferably, on the pressing plate position corresponding with pulling the tight sense of rotation of padlock be provided with bossed can with pull the contacted locating column of button.Pull button and be eccentric structure, pull the button rotation and can cross this position clamping force will diminish, locating column is set just can will pulls the position of button rotation back control maximum clamping force through the position of maximum clamping force.
As preferably, fixing column is square, and the neutral position of pressing plate is provided with the square hole that matches with fixing column, and the end of fixing column is provided with the rotary shaft hole vertical with fixing column, pulls button and is hinged to rotary shaft hole by rotating shaft.Square hole and the fixing column formation guide structure that matches is pulled the button rotation simultaneously pressing plate is depressed, and squarely can prevent the pressing plate rotation, guarantees that the clamping slot on the pressing plate concerns with the position between the clamping slot on the base.
As preferably, pull the length of the width of button greater than square hole, the eccentric face of pulling button is towards pressing plate.The relation of pulling between button and the square hole guarantees to pull button energy of rotation clamping platen.
The beneficial effects of the utility model are: the clamping slot of at least two symmetries is set between base and the pressing plate, and under the effect of pulling button, base and pressing plate are clamped in pipe fitting in the clamping slot, two pipe fittings can be clamped simultaneously.
