Abstract
The utility model discloses an electromagnet coil framework. The electromagnet coil framework comprises an outer barrel body (1) which is used for winding coils on the inner part, and side baffle plates (2) which are respectively arranged on the outer barrel body (1), wherein the two side baffle plates (2) are integrally formed on the outer barrel body (1); center of each side baffle plate (2) is provided with an inner barrel body (3) which is coaxial with the outer barrel body (1) in a mode of inward extending; center holes (31) matched with a guide sleeve are formed on the inner barrel bodies (3); and a sealing slot (31) is respectively arranged on the inner wall of each inner barrel body (3). The electromagnet coil framework disclosed by the utility model is equipped with the inner barrel bodies, and the sealing slots are arranged on the inner barrel bodies, so that probability that a liquid in a valve enters the coils is lowered, and safety of the electromagnet is improved.
Description
Technical field
The utility model relates to a kind of electromagnet, is specifically related to a kind of electromagnet coil skeleton.
Background technology
Electromagnet is widely used in the various valves in the hydraulic system of plant equipment, electromagnet comprises coil, armature, guide pin bushing, housing, end cap and coil rack, on armature, be provided with inserted link, inserted link stretches out outside end cap, between inserted link and end cap, be provided with sealing device, coil rack is arranged between guide pin bushing and housing, this magnet spool skeleton is for coiling, but between coil rack and guide pin bushing, be not provided with sealing device, in the time that the sealing device between inserted link and end cap is damaged, in valve, liquid can flow into from the gap between skeleton and guide pin bushing, cause coil short, cause valve normally not use, when serious, may cause whole hydraulic system spring.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to provide a kind of liquid that reduces and enters the probability of coil and improve the electromagnet coil skeleton of the fail safe of electromagnet.

Fig. 2 is the bottom surface structure schematic diagram of the utility model electromagnet coil skeleton.
Fig. 3 is the horizontal section structural representation of the utility model electromagnet coil skeleton.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The stereochemical structure of the utility model electromagnet coil skeleton as shown in Figure 1, its bottom surface structure as shown in Figure 2, its cross-section structure as shown in Figure 3, this electromagnet coil skeleton comprises the inner outer cylinder body 1 for coiling, and be separately positioned on the side shield 2 on outer cylinder body 1, two side shields 2 are all on one-body molded cylindrical shell outside 1, the center of each side shield 2 inner barrel 3 coaxial with outer cylinder body 1 that all extend internally, on inner barrel 3, offer the centre bore 32 matching with guide pin bushing, on the inwall of each inner barrel 3, all offer seal groove 31, in sealing groove 31, sealing ring is installed.The setting of inner barrel can prevent that coil from exceeding and affecting the installation of coil rack and guide pin bushing, has improved the convenience that coil rack is installed.
Outer cylinder body 1 is set to the first fillet 5 side shields 2 with the junction of side shield 2 and is set to the second fillet 6 with the junction of inner barrel 3.The setting of fillet, has avoided the right angle setting in existing design, has increased magnetic flux area, has reduced magnetic resistance, and the magnetic line of force can be passed through swimmingly, has increased electromagnetic force.
On the outer wall of outer cylinder body 1, be evenly provided with multiple strip bulges 7, this strip bulge 7 is semicylinder, and in the present embodiment, the quantity of strip bulge is 12.The setting of strip bulge makes outer cylinder body be convenient to line with the way of contact of housing to contact, avoid, because the mismachining tolerance of outer cylinder body and housing causes the phenomenon not packing into, being also convenient to the installation of outer cylinder body, improved electromagnet installation effectiveness.
The utility model is provided with inner barrel, offers seal groove on inner barrel, has reduced liquid in valve and has entered the probability of coil, the fail safe that has improved electromagnet.
These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
