Abstract

The utility model discloses a metal bar connector, which belongs to the technical field of metal welding. The connector of the utility model comprises connecting pipes sheathed on the outer sides of two joints and an explosive layer and a protecting layer which are coated at the outer sides of the connecting pipes. The utility model with novel design and idea can provide convenience to metal bar welding of high layer building industries and operation in fields and remote mountain areas.

Description

A kind of connector

The utility model relates to the metal welding techniques field, especially relates to a kind of blast connector that metal bar connects that is used for.

The fixed connection method that is widely used in the metal club-shaped material at present mostly adopts electric welding or gas welding etc., the enforcement of these methods must depend on special equipment, as electric welding machine, oxygen cylinder etc., and also have auxiliary equipment and professional operating personnel such as specific purpose tool, these conditions in the open air or outlying mountain area's operation be too far behind to catch up, particularly at engineering first-aid repair, then more need shorten the time and raise the efficiency as the connection that need carry out metal bar in speedily carrying out rescue work, therefore the research of metal bar method of attachment and instrument is more and more to adapting to varying environment, and ensuring the quality of products and raising the efficiency proposes new problem.

The purpose of this utility model is to improve the deficiency of prior art, and provides a kind of energy to be suitable for the varying environment requirement, guarantees the bar quality of connection, improves the connector that metal bar connects that is used for of operating efficiency.

The purpose of this utility model is achieved in that a kind of connector, comprises the splicing sleeve that is socketed in side outside two connectors, and its special character is that this connector comprises explosive layer and the protective layer that contain in the splicing sleeve outside.

Compared with the prior art the utility model has following good effect: the first is taked to be provided with explosive layer and protective layer in the outside of splicing sleeve owing to this device, only need a flame detonator or the electric cap ignition charge layer can affixed two metal bar joints, no matter thereby under which kind of condition, all can adapt to; It two is that the operating process of this device is simple, makes two bar joints in conjunction with firmly after the blast, reliable in quality, and can finishing in operating process only several seconds, and the operating efficiency height is compared with electric welding, gas welding and to be had tangible operation effectiveness; Its three since this apparatus structure simple, easy to operate, need not power supply and special equipment, instrument and professional, saving equipment and investment in human resources.

The concrete structure of a kind of connector of the utility model is provided by the following drawings and embodiment.

Fig. 1 is the structural representation of a kind of connector of the utility model.

Fig. 2 is another structural representation of a kind of connector of the utility model.

Fig. 3 is that the A of Fig. 2 is to view.

Describe the detail and the operation principle of a kind of connector of the utility model in detail below in conjunction with accompanying drawing.

Embodiment 1

A kind ofly be applicable to double thread steel or the fixedly connected connector (referring to accompanying drawing 1) of round steel in field construction or the open-air pole guy, with the material of seamless steel pipe as splicing sleeve 1, process the size of certain-length as requested, and be processed with 3 * 60 ° chamfering at the circular port inwall of both ends of the surface 4, remove impurity such as greasy dirt on the steel pipe circular port inside and outside wall, rust staining then with cleaning agent; The too newborn explosive of the stratiform of 5 millimeters thick (slurry explosives) made that length dimension than splicing sleeve 1 lacks 20 millimeters strip and with it tightly around the outside of splicing sleeve 1, other make wide be 50 millimeters the too newborn explosive of strip (slurry explosives) layer at both ends the too newborn explosive outside each tightly around a week, so that form explosive layer 2; After this tightly enclose around explosive layer 2 with the waxdip moistureproof paper, to form protective layer 3 around 3-5.More than constitute the static structure of a kind of connector of the utility model.

Embodiment 2

A kind of connector (referring to accompanying drawing 2) that under field construction or the certain environmental conditions polygon steel is connected that is applicable to, make the material of splicing sleeve 1 with seamless Steel Bar During or equal strength carbon steel bar, process the size of certain-length as requested, and endoporus is processed into is regular hexagon, and the inwall end of both ends of the surface 4 is processed with 3 * 45 ° chamfering, then with impurity such as the greasy dirt on cleaning agent removal splicing sleeve 1 inside and outside wall, rust stainings; Make that tubulose and the outside are matrix the trinitrotoluene of the constant weight die cavity of packing into and the uniform one charge tube 2 of density; and with suit splicing sleeve 1 in the tube chamber of charge tube 2; two ends differ 10 millimeters; immerse low temperature paraffin behind the suit; tightly enclose around explosive layer 2 with moistureproof paper again, and form protective layer 3 with paraffin bonding back around 3-5.More than constitute another static structure of a kind of connector of the utility model.

When this connector is being used for Steel Bar During when fixedly connected; as long as required two fixedly connected joints are inserted the inner chamber of the splicing sleeve 1 of this connector that is suitable for; after an end of protective layer 3 is fixed 8# flame detonator (or 8# electric cap) with the mode of adhesive tape or rope binding; light (or power supply) with fire and detonate, can finish the fixedly connected of two metal bars.As for increasing the bonding strength between two metal bars, can be processed with screw thread with suitable screw die in its periphery respectively at the leading portion of two joints, to increase the intensity between splicing sleeve 1 and two joints.

Claims

1, a kind of connector comprises the splicing sleeve that is socketed in side outside two connectors, it is characterized in that this connector comprises explosive layer and the protective layer that contain in the splicing sleeve outside.

2, connector according to claim 1 is characterized in that described splicing sleeve tube chamber is a circle hole shape, also can be polygon, and its end face inner chamber is provided with chamfering.

3, connector according to claim 1 and 2 is characterized in that described explosive layer shape is concave shape, and density evenly and be one also can superpose for multilayer.

4, connector according to claim 1 and 2 is characterized in that described protective layer is to be twined by moistureproof waxed paper to be wrapped to form, also can dipping one deck paraffin after and winding package paper.
