Abstract
The invention discloses an isolating type screw assembly. The isolating type screw assembly comprises a rod and an isolating sleeve, wherein a head is arranged on the top of the rod; a conical part is arranged at the bottom end of the rod; threads are respectively arranged on side surfaces of the conical part and the rod; a spring washer is arranged on the lower surface of the head and sleeves the rod; a cross-shaped groove is formed in the center of the upper surface of the head; a circle of inner slots and a circle of outer slots are successively formed between the cross-shaped groove and the edge of the upper surface of the head from inside to outside; and inner projections and outer projections which are matched with the inner slots and the outer slots are respectively arranged on the inner surface of the isolating sleeve. The screw assembly is simple structure and convenient to manufacture and use, and the spring washer is combined to the isolating sleeve, so that a screw can be effectively isolated from the outside after being mounted. The isolating type screw assembly has good insulation and waterproof properties, and is particularly suitable for assembling and positioning mounting of a high-precision instrument which is used in a severe environment.
Description
Technical field
The present invention relates to a kind of screw, be specifically related to a kind of isolated screw assembly.
Background technology
At present, the screw on market is of a great variety, and purposes is different, has good connection or fastening effect, because it is easy to use, so being widely used in every field.
When assembling some high precision instruments, in order to simplify assembling procedure or reduce assembly cost, conventional screw is generally adopted to be fastenedly connected, after a period of time, screw often gets rusty, and instrument also needs to guarantee bolt portion ground connection, nothing electric leakage before measuring, or directly breaking insulating cement at the exposed parts of screw, but insulating cement easily peels off after doing, effect is undesirable.
Summary of the invention
The technical problem to be solved is to provide a kind of isolated screw assembly with good insulation, water resistance.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of isolated screw assembly, including bar portion and separation sleeve, the top in bar portion is provided with head, bottom is provided with tapering, the side in tapering and bar portion is equipped with screw thread, the lower surface of head is provided with elastic washer, elastic washer is set in bar portion, the central authorities of head upper surface are provided with cross recess, from inside to outside it is sequentially provided with in a circle slot between cross recess and the edge of head upper surface and one encloses outer slot, the inner surface of separation sleeve is respectively equipped with the internal projection with interior slot and extrapolation slot fit and outer lug.
Described interior slot and outer slot are crisscross arranged.
Described interior slot is at least two, and the quantity of outer slot is consistent with interior slot.
Described internal projection, outer lug and separation sleeve are one-body molded.
Described internal projection, outer lug, separation sleeve and elastic washer are made by insulative water-proof rubber.
Described head, bar portion and tapering are one-body molded.
Compared with prior art, the invention have the advantage that the screw assembly simple in construction of the present invention, make and easy to use, adopt elastic washer in conjunction with the mode of separation sleeve, make screw can be effectively isolated with the external world after installing, there is good insulation, water resistance, be particularly suitable for the assembling of high precision instrument and the location and installation that use in the presence of a harsh environment.

Fig. 2 be in the present invention A-A to structural representation；
Fig. 3 is the sectional structure schematic diagram of separation sleeve in the present invention.
Wherein, 1, head, 11, cross recess, 2, elastic washer, 3, bar portion, 31, tapering, 4, separation sleeve, 5, outer slot, 51, outer lug, 6, interior slot, 61, internal projection.
Detailed description of the invention:
As shown in Figure 1 to Figure 3, a kind of isolated screw assembly, including bar portion 3 and separation sleeve 4, the top in bar portion 3 is provided with head 1, bottom is provided with tapering 31, head 1, bar portion 3 and tapering 31 are one-body molded, the side in tapering 31 and bar portion 3 is equipped with screw thread, the lower surface of head 1 is provided with elastic washer 2, elastic washer 2 is set in bar portion 3, the central authorities of head 1 upper surface are provided with cross recess 11, from inside to outside being sequentially provided with in a circle between the edge of cross recess 11 and head 1 upper surface slot 6 and one encloses outer slot 5, interior slot 6 is at least two, the quantity of outer slot 5 is consistent with interior slot 6, and interior slot 6 and outer slot 5 are crisscross arranged, the inner surface of separation sleeve 4 is respectively equipped with the internal projection 61 and outer lug 51 that coordinate with interior slot 6 and outer slot 5.
In the present invention, internal projection 61, outer lug 51 are one-body molded with separation sleeve 4, internal projection 61, outer lug 51, separation sleeve 4 and elastic washer 2 are made by insulative water-proof rubber, after screw pierces parts, internal projection 61 on separation sleeve 4 and outer lug 51 being respectively aligned to interior slot 6 and outer slot 5 and is pressed into, the bottom of separation sleeve 4 contacts with elastic washer 2, to play buffer action, the contact site of elastic washer 2 and separation sleeve 4 can heat fusion, with further up to insulation, waterproof effect；Tapering 31 can make bar portion 3 be more easy to and pierce parts, time saving and energy saving.
