Abstract
The utility model discloses a fastening structure of an electromagnetic valve coil, which includes a main body, a coil, a solenoid, an O-shaped ring and a coil fastening nut, wherein the solenoid is locked on the main body; the coil is sleeved on the solenoid; the O-shaped ring is sleeved on the solenoid and locked through the coil fastening nut; a hub shaped groove matched with the coil fastening nut is arranged on the joint surface of the coil and the coil fastening nut; anticlockwise radial convex ribs are arranged on the tight fit surface of the coil fastening nut and the coil, and the included angle between the convex ribs and the rotating diameter is 15 DEG; a regular hexagonal structure convenient for using a spanner is arranged on the non-tight fit surface of the nut; and 8 friction-reducing strip-shaped convex points are arranged on the contact surface of the inner hole of the coil fastening nut and the solenoid. The fastening structure of the electromagnetic valve coil solves the problems in the mounting and using processes that the nut is stripped, loosened and inconvenient to maintain through changing the thread material composition and the fastening and mounting structure.
Description
Technical field
The utility model relates to a kind of electromagnetic valve coil fastening structure, the particularly fastening nut of this electromagnetic valve coil fastening structure.
Background technique
The solenoid valve that in hydraulic system, uses at present, what its coil fastening nut material adopted is Reinforced Nylon 66 engineering plastics, and the pneumatic tool through special use is in addition fastening, and fastening structure all is simple screw threads for fastening.In actual use; Causing the sliding tooth of nut to reach easily when often shaking for a long time when pneumatic gun is tightened and in the using process of valve group owing to its simple screw threads for fastening structure becomes flexible; Use special-purpose pneumatic tool fastening simultaneously, extremely inconvenient for the later period maintenance of solenoid valve.
The model utility content
The utility model technical problem to be solved is a kind of electromagnetic valve coil fastening structure of design, to improve sliding tooth, loosening the reach problems such as keeping in repair inconvenience of nut in installation and using process.
For solveing the technical problem, the utility model comprises: body, coil, electric screwed pipe, O shape circle and coil fastening nut; Electric screwed pipe is locked at above the body, and coil is enclosed within above the electric screwed pipe, and O shape snare is locked through the coil fastening nut on electric screwed pipe; Coil has the wheel hub connected in star that cooperates the coil fastening nut with coil fastening nut junction plane; Coil fastening nut and coil close-fitting face have the convex tendon of counterclockwise radiation; And this convex tendon and rotating diameter are 15 ° of angles; The non-close-fitting face of nut has the convenient spanner regular hexagon structure of using, and the endoporus of coil fastening nut and electric screwed pipe surface of contact have 8 long strip salient points that reduce to rub.
The positive progressive effect of the utility model is: through changing the fastening mounting structure of thread material composition, improve sliding tooth, loosening the reach problems such as keeping in repair inconvenience of nut in installation and using process to reach.

Embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.
Shown in Fig. 1, Fig. 2, Fig. 3 A, Fig. 3 B, the utility model comprises body 1, coil 2, electric screwed pipe 3, O shape circle 4 and coil fastening nut 5; Electric screwed pipe 3 is locked at above the body 1, and coil 2 is enclosed within above the electric screwed pipe 3, and O shape circle 4 is enclosed within above the electric screwed pipe 3 through 5 lockings of coil fastening nut; Coil 2 has the wheel hub connected in star that cooperates coil fastening nut 5 with coil fastening nut 5 junction planes; Coil fastening nut 5 and coil 2 close-fitting faces have the convex tendon 51 of counterclockwise radiation; And this convex tendon and rotating diameter are 15 ° of angles; The non-close-fitting face of nut has the convenient spanner regular hexagon structure 52 of using, and the endoporus of coil fastening nut 5 and electric screwed pipe 3 surface of contact have 8 long strip salient points 53 that reduce to rub.
Wherein, body is the cuboid cast iron workpiece that the runner design is arranged; Coil is the workpiece that the copper wire winding is arranged, and energising can produce electromagnetic force, and coil has the wheel hub connected in star that cooperates the coil fastening nut with coil fastening nut junction plane; Electric screwed pipe is an accurate processing assembly parts, uses with the coil collocation; O shape loop material is that nitrile rubber is used for the water vapor seal between coil and the electric screwed pipe; Coil fastening nut material adopts Reinforced Nylon 66 to add 20% glass fibre; Itself and coil close-fitting face have the convex tendon of counterclockwise radiation; And this convex tendon and rotating diameter are 15 ° of angles; The non-close-fitting face of coil fastening nut has the convenient regular hexagon structure of using spanner, and coil fastening nut and endoporus and electric screwed pipe surface of contact have 8 long strip salient points that reduce to rub, and are used for fastening coil and cooperate with body.
Electric screwed pipe is locked at above the body; Coil closely cooperates with body on electric screwed pipe through coil fastening nut, O shape snare, and coil electricity produces magnetic field, and the push rod in the render electrical screwed pipe is released; Coil loosening with the electric screwed pipe collocation position not at that time; Electric screwed pipe thrust performance can obviously descend, and functional issues can appear in solenoid valve, so the locking property of coil fastening nut has proposed very high requirement.
The utility model has been done following 4 breakthrough designs when the coil fastening structure is improved:
The firstth, the material composition of coil fastening nut has been made improvement, adopted engineering plastics Reinforced Nylon 66 to add the composition of 20% glass fibre, this combined material has improved the yield strength that the nut gear thread part divides greatly.
The secondth, coil fastening nut and coil registration interface designs be the convex tendon of 15 ° of counterclockwise radiation with rotating diameter; When clockwise tightening nuts; Increased the torsion of rotary nut; Prevented the generation of sliding tooth, convex tendon cooperates with groove above the coil, and it is loosening to prevent well that coil from causing in the vibrations process.
The 3rd is the regular hexagon structure that has designed convenience use spanner at the non-close-fitting face of nut, and has designed anti-skidding groove at each face of hexagonal.
The 4th is to have designed 8 long strip salient points that reduce to rub at coil fastening nut endoporus and electric screwed pipe surface of contact, when utilizing the salient point guiding, guarantees that nut is concentric with electric threaded pipe, has reduced the friction between nut and the electric screwed pipe simultaneously.
Though more than described the embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these mode of executions.Therefore, the protection domain of the utility model is limited appended claims.
