Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, and in particular to an aluminum cast adapter pipe that is easy to connect and fix. Background Technology

[0002] Aluminum alloy casting is a process in which molten aluminum alloy is poured into a mold and cooled to solidify to obtain a casting with the desired shape and performance. Among them, aluminum cast adapters produced by aluminum alloy casting are joints used to connect or switch pipelines. These products are widely used in industry, agriculture, fire protection and automotive modification due to their lightweight, corrosion resistance and good mechanical properties.

[0003] In existing aluminum cast pipe fittings, the connection to the pipeline is generally fixed with bolts. When aligning the aluminum cast pipe fitting with the flange at the end of the pipeline, multiple adjustments are required to align the mounting holes on the flange, which is cumbersome. Current solutions typically involve installing a positioning block on the flange mating head of the aluminum cast pipe fitting to engage with the mating slot on the pipeline port for positioning. However, this also requires multiple adjustments to ensure proper engagement of the positioning block and slot, which is similarly cumbersome. These factors contribute to the inconvenience of connecting aluminum cast pipe fittings.

[0004] Therefore, this utility model proposes an aluminum cast adapter that is easy to connect and fix to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum cast adapter that is easy to connect and fix, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum cast adapter that is easy to connect and fix, comprising an adapter body and a connecting flange disposed on the adapter body; the connecting flange is further provided with bolt mounting holes for bolt connection; The connecting flange on the main body of the adapter pipe is mated with the connecting flange at the end of the connecting pipe, and is pre-positioned by a set calibration and positioning component.

[0007] Preferably, the calibration positioning component includes a positioning guide block fixedly disposed on the connecting flange side of the adapter head body; One of the positioning guide blocks is fixedly installed on each of the four sides of the connecting flange.

[0008] Preferably, a guide auxiliary slope is provided at the bottom front end of the positioning guide block.

[0009] Preferably, a connecting screw groove is also provided on the front end face of the positioning guide block.

[0010] Preferably, the calibration and positioning component further includes auxiliary components; The auxiliary component includes a stabilizing pressure plate with a through-hole, and the stabilizing pressure plate and the positioning guide block are fixedly connected by fastening screws.

[0011] Preferably, an auxiliary filling ramp is provided on one side of the stabilizing pressure plate, which is used in conjunction with the guide auxiliary ramp on the bottom side of the front end of the positioning guide block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model designs an aluminum cast adapter that is easy to connect and fix, which includes an adapter body and a connecting flange provided on the adapter body; the connecting flange is also provided with bolt mounting holes for bolt connection; wherein the connecting flange on the adapter body is mated with the connecting flange at the end of the adapter, and is pre-positioned by a set calibration and positioning component.

[0013] For the installation and connection of the adapter pipe body and the connecting pipe, a calibration and positioning component is set to provide a pre-positioning effect to improve the connection convenience of the adapter pipe body. Specifically, this solution sets positioning guide blocks on the four sides of the connecting flange on the adapter pipe body.

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution: an aluminum cast adapter that is easy to connect and fix, including an adapter body 1 and a connecting flange 3 provided on the adapter body 1; the connecting flange 3 is also provided with bolt mounting holes 4 for bolt connection; The connecting flange 3 on the main body 1 of the transfer pipe is connected to the connecting flange 3 at the end of the connecting pipe 2, and is pre-positioned by the set calibration and positioning components.

[0018] For the installation and connection of the adapter connector body 1 and the connecting connector 2, a calibration and positioning component is set to provide a pre-positioning effect to improve the connection convenience of the adapter connector body 1. Specifically, this solution sets positioning guide blocks 501 on the four sides of the connecting flange 3 on the adapter connector body 1. When the connecting flange 3 on the adapter connector body 1 and the connecting flange 3 at the end of the connecting connector 2 are connected, the positioning guide blocks 501 can quickly align the two connecting flanges 3, thereby aligning the bolt mounting holes 4 on the two connecting flanges 3, avoiding multiple debugging operations. Moreover, this pre-positioning work is easy to observe and convenient for operators.

[0019] According to the appendix Figure 1-2 As shown, the calibration and positioning component includes positioning guide blocks 501 fixedly installed on the side of the connecting flange 3 on the adapter body 1. One positioning guide block 501 is fixedly installed on each of the four sides of the connecting flange 3. That is, when the adapter body 1 and the connector 2 are connected and installed, the connecting flange 3 on the adapter body 1 is aligned with the connecting flange 3 at the end of the connector 2. During this process, it is necessary to ensure that the bolt mounting holes 4 on the two connecting flanges 3 are quickly aligned to avoid multiple adjustments, thus improving the installation efficiency of the adapter body 1. Specifically, the positioning guide blocks 501 on the four sides of the connecting flange 3 on the adapter body 1 move to the side positions of the connecting flange 3 at the end of the connector 2, i.e., the positioning guide blocks 501 contact the connecting flange 3 at the end of the connector 2, thereby providing a limiting action to ensure that the connecting flange 3 on the adapter body 1 is aligned with the connecting flange 3 at the end of the connector 2.

[0020] Then from the appendix Figure 2As shown, when the connecting flange 3 on the main body 1 of the adapter pipe is connected to the connecting flange 3 at the end of the connector pipe 2, that is, when the positioning guide block 501 on the side of the connecting flange 3 on the main body 1 of the adapter pipe contacts and limits the connection with the side of the connecting flange 3 at the end of the connector pipe 2, in order to improve its convenience.

[0021] This solution also provides a guide auxiliary slope 502 at the bottom front end of the positioning guide block 501. The purpose of setting the guide auxiliary slope 502 here is that when the positioning guide block 501 is docked and limited with the connecting flange 3 at the end of the connecting pipe head 2, if the end side wall of the connecting pipe head 2 comes into contact with the guide auxiliary slope 502, the connecting flange 3 on the main body 1 of the adapter pipe head can be pressed, so that the two connecting flanges 3 can also be quickly released. Here, the guide auxiliary slope 502 can reduce the end cotton area at the front end of the positioning guide block 501. That is, when the positioning guide block 501 is limited with the connecting flange 3 at the end of the connecting pipe head 2, if the positioning guide block 501 comes into contact with the front side of the connecting flange 3 at the end of the connecting pipe head 2, it will block the positioning guide block 501. However, when the front side of the connecting flange 3 at the end of the connecting pipe head 2 comes into contact with the guide auxiliary slope 502, the docking and limiting work of the connecting flange 3 can continue, which has better operational flexibility.

[0022] Combined with the appendix Figure 3-4 As shown, after the positioning guide block 501 in the calibration positioning assembly sets the connection flange 3 on the adapter body 1 and the connection flange 3 at the end of the adapter 2 for docking and limiting, the two connection flanges 3 are then fixedly connected with bolts.

[0023] To further improve its stability, this solution also provides a connecting screw groove 503 on the front end face of the positioning guide block 501; the calibration positioning component also includes an auxiliary component; the auxiliary component includes a stabilizing pressure plate 601, in which a through insertion hole 602 is provided, and the stabilizing pressure plate 601 and the positioning guide block 501 are fixedly connected by fastening screws 603; an auxiliary filling inclined block 604 is also provided on one side of the stabilizing pressure plate 601, which works in conjunction with the guide auxiliary inclined surface 502 on the bottom side of the front end of the positioning guide block 501.

[0024] That is, after connecting the connecting flange 3 on the main body 1 of the adapter pipe and connecting the connecting flange 3 at the end of the connector pipe 2 with bolts, the auxiliary filling inclined block 604 on one side of the stabilizing pressure plate 601 is inserted into the guide auxiliary inclined surface 502 on the bottom front side of the positioning guide block 501. At the same time, the stabilizing pressure plate 601 contacts the connecting flange 3 at the end of the connector pipe 2. Finally, the stabilizing pressure plate 601 is fixed with the fastening screw 603. That is, the fastening screw 603 is inserted into the through hole 602 on the stabilizing pressure plate 601 and then threaded into the connecting screw groove 503 at the end of the positioning guide block 501 until the fastening screw 603 is tightened. This provides an auxiliary function for the connection stability between the connecting flange 3 on the main body 1 of the adapter pipe and the connecting flange 3 at the end of the connector pipe 2.
