Abstract
The utility model relates to a high temperature adjacent switch box. The bottom part of the box body is provided with a passage groove which is concave toward an internal cavity of the box body, a movable piece is arranged in the passage groove and is matched with the passage groove. The bottom part of the passage groove is provided with a peeping groove; a peeping hole is arranged on the corresponding part of a box cover; an electroplating metal plate is fixed on the bottom part of the box body through a fixing device. In addition, the buckling positions between the box cover and the box body are all provided with seal washers The utility model with favorable sealing performance and convenient assembly and disassembly can be installed on a high temperature piece and can be used in harsh environments of oil stains, corrosion, moisture, etc.
Description
The utility model relate to a kind of on high-temperature component, install and use near switch enclosure.
Near switch with the reliability height, maintenance workload is little, in the stroke field of switches, use more and more extensivelyr, but mostly be exposed installation, lead-in wire is easily bumped disconnected, and is easily aging again in oil pollution environment, is made of electronic devices and components near switch, on high-temperature component, install, can Yin Wendu too high and can't work.
Though have a kind of at present near switch enclosure, can be with in being installed near switch, but this switch enclosure is not structurally considered provision for thermal insulation, can not on high-temperature component, install and use, the fang bolt hole of this switch enclosure is in switch enclosure in addition, and dismounting is extremely inconvenient, and the displacement of movable member is subjected to the restriction of box body length, the taking-up of movable member also needs the box body of this switch is pulled down, and brings difficulty to maintenance.
The purpose of this utility model is to provide a kind of installation, maintenance convenient, and the movable member stroke is unrestricted, and cable can directly be introduced in the box, good airproof performance, and the high temperature modification that can install on high-temperature component is near switch enclosure.
The utility model is realized by following measure:
A kind of high temperature modification is near switch enclosure, comprise box body 10, be located at the lid 14 on the box body 10, its special character is, in the described box body 10 is near switch inner chamber 1, described box body 10 bottoms are provided with recessed channel slot 7 to inner chamber 1, movable member 2 is located in the channel slot 7 and is slidingly matched with it, and described channel slot 7 bottoms are provided with spies on groove 5, and described box body 10 bottoms are provided with by the fixing with it plated metal plate 8 of fixture 18; Described lid 14 be provided with box body 10 on spy on the corresponding peep-hole 15 in groove 5 positions, described lid 14 is equipped with seal washer 13 with edge, the contact matching position, center of box body 10.
Box body of the present utility model can be provided with outer convex edge 4 on 10 limits, and its edge of spying on groove 5 is provided with interior convex edge 3; Described lid 14 edges are provided with the seal groove 17 that is meshed with described outer convex edge 4, and the edge of the peep-hole 15 of described lid 14 is provided with the seal groove 16 that is meshed with described interior convex edge 3.
Fixed bin body 10 of the present utility model can comprise fang bolt 19 with the fixture 18 of plated metal plate 8, described box body 10 is provided with the cushion cover 12 that both are separated with the fang bolt 19 of plated metal plate 8 links, and the other end of described fang bolt 19 is provided with packing ring 20.
Fixture 18 of the present utility model can be arranged at the outside of box body 10.
The side of the utility model box body 10 can be provided with the line cushion rubber 9 excessively of lead-in cable line.
The accompanying drawing drawing is described as follows:
Fig. 1 is the structural representation of the utility model box body.
Fig. 2 is the structural representation of the utility model lid.
Fig. 3 is an end view of the present utility model.
Fig. 4 is the structural representation of the fixture of the utility model fixed gas and plated metal plate.
Each label declaration is as follows among the figure:
1-is near the switch inner chamber, convex edge in the 2-movable member, 3-, the outer convex edge of 4-, 5-spies on groove, 6-fang bolt hole, 7-channel slot, 8-plated metal plate, 9-crosses the line cushion rubber, 10-box body, 11-fang bolt hole, the 12-cushion cover, 13-seal washer, 14-lid, the 15-peep-hole, 16-seal groove, 17-seal groove, the 18-fixture, 19-fang bolt, 20-packing ring.
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to accompanying drawing 1～2, can place inner chamber 1 near switch, its position can longitudinally be adjusted, and when movable member 2 longitudinally arrives precalculated position near switch, can post a letter near switch.By accompanying drawing 1 as seen, channel slot 7 is a groove, allows movable member 2 to shift out along channel slot 7, thereby makes the stroke of movable member 2 unrestricted, and 7 pairs of movable members of groove 2 also have guide effect, and the assurance switch is reliably posted a letter.When lid 14 was removed, movable member 2 can be taken out above spying on groove 5, is convenient to the dismounting of movable member 2.By Fig. 3～4 as seen, fang bolt hole the 6, the 11st, on two diagonal angle external ears of box body 10, the corresponding position of lid 14 is also removed one, and the dismounting of the utility model switch enclosure is just more convenient like this.
The interior convex edge 3 of box body 10, outer convex edge 4 are meshed with the seal groove 16,17 of lid 14, are provided with seal washer 13 in the seal groove 16,17, and cable is introduced by crossing line cushion rubber 9, and these have guaranteed that the utility model has better seal.The central authorities of lid 14 are provided with peep-hole 15, cooperate the situation of movement that can observe movable member 2 with the groove 5 of spying on of box body 10.
For reducing heat conduction, fang bolt of the present utility model has only two, to reduce heat conduction path, be with thermal resistance bigger cushion cover 12 and packing ring 20 on the screw 19, cushion cover 12 and packing ring 20 can be made of exotic materials such as phenolic plastics, this switch enclosure relies on cushion cover 12 that it is built on stilts, and making between itself and the high-temperature component has a space, and air circulates betwixt.
For reducing thermal radiation plated metal plate 8 is housed also between switch enclosure and high-temperature component, make the thermal radiation of high-temperature component can not direct projection to box body 10.
Near switch, the utility model can adopt exotic material making such as phenolic plastics, near switch, can adopt nonmagnetic metal die casting such as aluminium, stainless steel for magnetic inductive for the metal induction type, and Passivation Treatment is carried out on the surface, strengthens corrosion resistance.
The utility model has solved the installation question of approach switch on high-temperature component, with existing Have technology to compare, installation and maintenance are convenient, and are simple in structure, good seal performance, and oil-stain-preventing, Anticorrosion, improvement can be used in the explosion-proof environment a little.
