Detailed Description

The present invention will be further explained with reference to the following embodiments and accompanying drawings.

In the embodiment, as shown in fig. 1 and fig. 2: the utility model provides a duplex connects, includes two coupling 1, still includes a connecting plate 2, the both sides of connecting plate 2 are welding portion 201, middle installation department 202 that is, the below welding of welding portion 201 coupling 1, establish mounting hole 203 on the installation department 202. This embodiment combines into a dual joint through a connecting plate 2 with two coupling 1, only needs fixed connection board 2 just can accomplish two couplings 1 and even two oil pipe's installation during the installation, and is convenient rapid, and whole pipeline arrangement is also more whole pleasing to the eye moreover. The pipe joint 1 in this embodiment has an outer hexagonal shape and an inner threaded shape at both ends, which is the most common type of joint, and the pipe joint 1 may be in another form.

In the embodiment, as shown in fig. 1 and fig. 2: the connecting plate 2 is a bending plate with two low sides and a high middle part, the welding part 201 is low, and the installation part 202 is high. The mounting portion 202 is higher than the welding portion 201, which has two advantages, that is, the mounting portion 202 has a larger adjustment margin when mounted, and the mounting and positioning of the connection plate 2 and the pipe joint 1 are facilitated.

In the example, as shown in fig. 4: the pipe joint 1 and the welding portion 201 have a contact surface, and both side edges of the contact surface are fixed by fillet welding. The positions of the two welding seams are respectively a and B in fig. 4, it should be noted that the welding seam at B is only an illustration, is not a real welding seam, and the welding seam at B cannot be welded when the connecting plate 2 and the pipe joint 1 are assembled in the mold.

In the examples, as shown in FIGS. 3 to 6: the utility model provides an assembly jig of duplex, includes lower mould 3 and last mould 4, lower mould 3 is equipped with twice parallel arrangement's holding tank 301, per pass single file, a plurality of coupling 1 can be placed in the holding tank 301, it is equipped with adsorption tank 401 to go up the bottom of mould 4, be equipped with rectangular form magnet 402 in the adsorption tank 401, adsorption tank 401 shape and 2 adaptations of connecting plate, adsorbable single file, a plurality of connecting plate 2, be equipped with the location assembly structure between lower mould 3 and the last mould 4. The assembly die of this embodiment can accomplish the equipment of multiunit duplex joint, and corresponding disposable welding that also can accomplish a plurality of coupling 1 has improved production efficiency. The two-dot chain line in figure 3 is a whole welding line, and a plurality of duplex joints can be welded at one time.

In the examples, as shown in FIGS. 3 to 6: the positioning and assembling structure comprises a positioning pin 302 arranged on the lower die 3 and a positioning hole 403 arranged on the upper die 4. The positioning pins 302 have a large chamfer at the upper end thereof for easy assembly, and generally, two positioning pins 302 arranged diagonally can satisfy the requirement.

In the examples, as shown in FIGS. 3 to 6: the lower die 3 is provided with a fixing bolt 303, and the upper die 4 is correspondingly provided with a fixing hole 404 and a nut 304. The nut 304 is not necessary here, and when the requirement for deformation prevention of the duplex joint is not high, the upper die 4 may use a weight or the like instead of the nut 304 to facilitate the operation.

In the examples, as shown in FIGS. 3 to 6: one end of the accommodating groove 301 is plugged with an adjusting sheet 305. Generally, the total length of the receiving groove 301 is not an integral multiple of the length of the pipe joint 1 due to the difference of the joint specifications or the joint error, so that it is necessary to provide the adjusting piece 305 for positioning and fastening the pipe joint 1, and the adjusting piece 305 has two ways of inserting an iron piece into a gap or welding a stop.

In the examples, as shown in FIGS. 3 to 6: handles 405 are arranged at two ends of the upper die 4. The lower die 3 and the upper die 4 are assembled tightly, and the disassembly is laborious. Typically, the lower moulds 3 are spot welded to the platform so that the upper moulds 4 can be easily removed by means of handles 405.

It is obvious that the above embodiments of the present invention are only examples for illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. There is no need or no way to give poor examples of all embodiments. And that such obvious changes and modifications are within the scope of the present invention as defined by the appended claims.
