Industry accessories, it is made of following sections: pressure cylinder, piston rod, piston, seal guide sleeve, filler (inert gas or
Person's gas mixture), control element and cylinder outer control element (referring to controllable gas spring) and connector etc. in cylinder, principle is closed
Inert gas is filled in pressure cylinder, and perhaps gas mixture makes the intracorporal pressure of chamber higher than several times or tens times of atmospheric pressure,
Realize the movement of piston rod to the pressure difference generated less than the cross-sectional area of piston using the cross-sectional area of piston rod.
Existing pneumatic rod structure is fixed, and cylinder barrel is that integral type cylinder needs after cylinder barrel internal damage by piston rod and end
Lid is unloaded and could be overhauled to cylinder barrel inside, and along with cylinder barrel diameter is narrow, bucket diameter is deep, and internal overhaul is more troublesome, to spread out
A kind of air-leg that cylinder barrel is removable, such as Publication No. CN207673645U are born, authorized announcement date is on July 31st, 2018,
The patent of entitled " a kind of air-leg just repaired ", the air-leg threadedly connect cylinder barrel and lower cylinder barrel,
And be fixedly connected using lock and lock ring, to realize the detachable of air-leg, facilitate maintenance, but screw thread is set and is agreed with
Degree requires relatively high, and technique is relatively cumbersome, must cooperate lock and lock ring, and input cost is high, is unfavorable for promoting the use of.
Utility model content
Existing above-mentioned in order to overcome the shortcomings of, the utility model provides a kind of splicing type air-leg, is existed by setting
The plug connector of splice ends realizes being detachably connected for cylinder barrel.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of splicing type air-leg, including cylinder
Cylinder, end cap and piston rod, cylinder barrel both ends are respectively arranged with left end cap and right end cap, and cylinder barrel is by left cylinder cylinder and right cylinder cylinder structure
Right cylinder cylinder end is socketed in by plug connector at, left cylinder cylinder, plug connector by be arranged in left cylinder cylinder end outer wall grafting boss and
The inserting groove that right cylinder cylinder end outer wall is arranged in is constituted, and grafting boss and inserting groove are adapted.
Further, including plug connector is at least provided with three groups, and plug connector is circumferentially uniform as the center of circle using cylinder barrel center
It is arranged in cylinder drum outer wall.
Further, including inserting groove is L-type, and inserting groove includes orthogonal guide groove and limiting slot.
Further, the inserted terminal including left cylinder cylinder and right cylinder cylinder is arranged with sealing ring by seccotine.
Further, the silica-gel antiskid set for increasing friction is equipped with including grafting boss outer cover.
The utility model has the beneficial effects that replacing existing threaded connection by simply plugging socket mode, not
Under the premise of influencing cylinder barrel sealing, so that the installing and dismounting of cylinder barrel is more convenient, the more conducively internal overhaul of cylinder barrel.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the grafting boss of the utility model and the grafting schematic diagram of inserting groove.
1. left end cap in figure, 2. right end caps, 3. left cylinder cylinders, 4. right cylinder cylinders, 5. grafting boss, 6. inserting grooves, 61. guiding
Slot, 62. limiting slots, 7. sealing rings, 8. silica-gel antiskid sets, 9. air bags, 10. piston rods.
Specific embodiment
If Fig. 1 is the structural schematic diagram of the utility model, a kind of splicing type air-leg, including cylinder barrel, end cap and piston
Bar 10, cylinder barrel both ends are respectively arranged with left end cap 1 and right end cap 2, and cylinder barrel is made of left cylinder cylinder 3 and right cylinder cylinder 4, left cylinder cylinder
3 are socketed in 4 end of right cylinder cylinder by plug connector, and plug connector is existed by the grafting boss 5 and setting that 3 end outer wall of left cylinder cylinder is arranged in
The inserting groove 6 of 4 end outer wall of right cylinder cylinder is constituted, and grafting boss 5 and inserting groove 6 are adapted, plug connector at least provided with three groups, and
Plug connector is circumferentially uniformly arranged on cylinder drum outer wall as the center of circle using cylinder barrel center, and the inserted terminal of left cylinder cylinder 3 and right cylinder cylinder 4 passes through
Seccotine is arranged with sealing ring 7, and 1 medial surface of left end cap is provided with the air bag 9 buffered for piston rod 10.In 3 end of left cylinder cylinder
Positioning table for being arranged right cylinder cylinder 4 is set, so that after right cylinder cylinder 4 is set in 3 end of left cylinder cylinder, the outer surface of left and right cylinder barrel is
It flushes, grafting boss 5 is arranged in the positioning table outer wall of left cylinder cylinder 3 by welding manner, it is convex that 4 end of right cylinder cylinder corresponds to grafting
Platform 5 offers inserting groove 6, when needing to be plugged and fixed, 4 sets of right cylinder cylinder is connected on left cylinder cylinder 3, certain angle is then turned over, makes
It obtains grafting boss 5 to be completely fixed with inserting groove 6, to realize being fixedly connected for left and right cylinder barrel, inserting mode is convenient and efficient, than passing
System thread connecting mode facilitates very much, and manufacture craft is also simple, is bonded with by seccotine on the Mosaic face of left and right cylinder barrel close
Seal 7 will not influence the normal use of air-leg to avoid the leakage of gas in cylinder barrel.
As shown in Fig. 2, inserting groove 6 is L-type, inserting groove 6 includes orthogonal guide groove 61 and limiting slot 62, and grafting is convex
5 outer cover of platform is equipped with the silica-gel antiskid set 8 for increasing friction, when fixed, the corresponding grafting boss 5 of guide groove 61 is inserted into, so
After turn over certain angle so that grafting boss 5 is transferred to limiting slot 62, to realize being fixedly connected for left cylinder cylinder 3 and right cylinder cylinder 4,
The silica-gel antiskid set 8 being arranged outside grafting boss 5 is conducive to increase the friction of grafting boss 5 and 6 inner wall of inserting groove, to prevent grafting convex
Platform 5 is deviate from, and the connective stability of left and right cylinder barrel is enhanced, and when needing to overhaul cylinder barrel inside, past need to only be plugged and fixed
Opposite direction rotates left cylinder cylinder 3, then extracts grafting boss 5 out of inserting groove 6, easy for assemble or unload quick, easily real
Now to the inspection operation inside cylinder barrel.
It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art
Understand, in the case where not departing from spirit and scope as defined in the appended claims, many modifications can be made, change or wait
Effect, but all will fall within the protection scope of the utility model.
