Therefore, owing to there is above-mentioned technological deficiency in prior art, be those skilled in that art's technical problems urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is for providing a kind of EX PACKING GLAND, and be intended to solve the EX PACKING GLAND existed in prior art and there is poor sealing performance, coefficient of safety is low, the problem of preventing dust fire performance difference.
For achieving the above object, the utility model provides following technical scheme:
A kind of EX PACKING GLAND, mainly comprise top connection body, lower contact body, annular groove, sealing bluff piece, first ring-shaped rubber pad, ring baffle, conical internal thread and leather packing, annular groove is provided with in described top connection body, the first ring-shaped rubber pad is provided with in described annular groove, described top connection body lower end connects sealing bluff piece, described sealing bluff piece is provided with external screw thread, described lower contact body upper center is provided with the conical internal thread coordinated with described sealing bluff piece, ring baffle is provided with outside described conical internal thread, described lower contact body bottom is provided with external screw thread, leather packing is provided with in the externally threaded end of described lower contact body bottom.
Preferably, also comprise the second ring-shaped rubber pad, described second ring-shaped rubber pad is located at the end of described ring baffle.
Usefulness of the present utility model is: by being provided with sealing bluff piece in top connection body bottom, and on lower contact body, be provided with the conical internal thread matched, thus can in wiring process along with threaded engagement gradually deeply, make fastening effect stronger; And be provided with leather packing in lower contact body bottom and be provided with the second ring-shaped rubber pad in the end of ring baffle, thus make sealing effectiveness stronger, effectively prevent entering of dust.The utility model structure is simple, easy to use, good dustproof effect, and joint connects closely, and explosion-proof performance is good.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
In figure: 1 is top connection body; 2 is lower contact body; 3 is annular groove; 4 is sealing bluff piece; 5 is the first ring-shaped rubber pad; 6 is ring baffle; 7 is conical internal thread; 8 is leather packing; 9 is the second ring-shaped rubber pad.
Embodiment
The utility model provides a kind of EX PACKING GLAND, and the utility model structure is simple, easy to use, good dustproof effect, and joint connects closely, and explosion-proof performance is good.
Below in conjunction with the accompanying drawing in the utility model embodiment, carry out clear and detailed description to the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of EX PACKING GLAND as shown in Figure 1, mainly comprise top connection body 1, lower contact body 2, annular groove 3, sealing bluff piece 4, first ring-shaped rubber pad 5, ring baffle 6, conical internal thread 7 and leather packing 8, annular groove 3 is provided with in described top connection body 1, the first ring-shaped rubber pad 5 is provided with in described annular groove 3, thus when the wiring such as cable enter, realize sealing effectiveness.Described top connection body 1 lower end connects sealing bluff piece 4, and top connection body 1 is fixedly connected with sealing bluff piece 4, realizes being connected with lower contact body 2 by sealing bluff piece 4.Described sealing bluff piece 4 is provided with external screw thread, described lower contact body 2 upper center is provided with the conical internal thread 7 coordinated with described sealing bluff piece 4, can in sealing bluff piece 4 and conical internal thread 7 connection procedure, the diameter reducing sealing bluff piece 4 gradually, thus clamping cables etc.Be provided with ring baffle 6 outside described conical internal thread 7, ring baffle 6 is for dust-break, and described lower contact body 2 bottom is provided with external screw thread, is provided with leather packing 8 in the externally threaded end of described lower contact body 2 bottom.When cable passes from lower contact body 2, by the effect of leather packing 8, can seal between cable and lower contact body 2, prevent dust etc. from entering.
Further, also comprise the second ring-shaped rubber pad 9, described second ring-shaped rubber pad 9 is located at the end of described ring baffle 6.Thus the sealing property that further enhancing between top connection body 1 and lower contact body 2, dirt exclusion capabilities is stronger.
By being provided with sealing bluff piece 4 in top connection body 1 bottom, and on lower contact body 2, be provided with the conical internal thread 7 matched, thus can in wiring process along with threaded engagement gradually deeply, make fastening effect stronger; And be provided with leather packing 8 in lower contact body 2 bottom and be provided with the second ring-shaped rubber pad 9 in the end of ring baffle 6, thus make sealing effectiveness stronger, effectively prevent entering of dust.The utility model structure is simple, easy to use, good dustproof effect, and joint connects closely, and explosion-proof performance is good.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.Be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
