Description

Technical Field

[0001] The utility model relates to the field of air ducts, in particular to a pseudo four-way connector used for staggered cross collision of air ducts. Background Art

[0002] An air duct is a piping system used to transport and distribute air. It is widely used in construction, industry and transportation. It plays an important role in air conditioning systems and ventilation systems and is used to transport air and air mixtures. The main functions of an air duct include ensuring the quality and comfort of indoor air. It can also be used for gas transportation and discharge in industrial production processes. When installing the air duct in a staggered cross-collision manner, a four-way connector is required. A four-way connector is a pipe fitting or pipe connector, also known as a pipe four-way or a four-way pipe fitting, a four-way joint, which is used at the branch point of the main pipeline. There are four-way connectors of equal diameter and different diameter. The ends of the equal-diameter four-way connectors are all the same size. The main pipe sizes of the different-diameter four-way connectors are the same, while the branch pipe sizes are smaller than those of the main pipes.

[0003] After searching, the pseudo four-way connector for the staggered cross collision of air ducts with announcement number CN218152831U specifically discloses a pseudo four-way connector for the staggered cross collision of air ducts, whose structure includes a box body with a rectangular shape and openings on four sides, each opening is respectively equipped with a connecting pipe, and the connecting pipes on two opposite surfaces of the box body are a group, totaling two groups, a partition plate is provided in the box body, and the box body is divided into two non-communicating areas by the partition plate and respectively connected to the two groups of connecting pipes, and the two groups of connecting pipes are respectively connected to two air ducts perpendicular to the horizontal plane. The advantages of the utility model: reasonable structural design reduces the difficulty of construction and the difficulty of duct layout processing, no need to bend up and down, easy to install, solves the problem of insufficient staggered space for narrow technical sandwich air ducts, solves the problem of pipeline growth, increased resistance and reduced wind speed due to bending and avoiding of air ducts, improves aesthetics, and can be produced in a standardized manner.

[0004] During use, the existing pseudo four-way connectors for staggered cross collision of air ducts need to be strengthened and fixed after the air duct connection is installed. Otherwise, if the air duct connection only relies on the internal pipe connection of the connector, when encountering situations such as external pipe dragging, it is easy for the pipe to detach from the connector, resulting in air duct leakage, etc., and the above-mentioned comparative cases also lack other means to strengthen the external pipe connection. Therefore, after long-term use, the ability to strengthen fixation is lacking. When the air duct dragging causes leakage at the connection, frequent manual maintenance is required, thereby delaying the use of the entire air duct.

[0005] Therefore, it is necessary to invent a pseudo four-way connector for staggered cross collision of air ducts to solve the above problems. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-5 A pseudo four-way connector for staggered cross collision of air ducts shown includes a four-way body 1, which is used to connect different air ducts;

[0028] The air duct opening 9 is arranged outside the cross-body 1, and is used for the air duct to pass through the cross-body 1, and a fixed slide groove 10 is opened on one side of the air duct opening 9, and a fixed slider 11 is movably connected inside the fixed slide groove 10, and a positioning bolt 12 is penetrated outside the fixed slider 11;

[0029] A cross-connecting plate 13 is arranged on one side of the fixed slider 11 and is used for connecting and installing a damping reset rod 14, and a clamping pipe clamp 15 is fixedly installed on one end of the damping reset rod 14. An anti-dropping pipe sleeve 16 is arranged on the outside of the clamping pipe clamp 15. When facing the dragging of the air duct, the anti-dropping pipe sleeve 16, which is larger than the clamping pipe clamp 15, will resist against one side of the clamping pipe clamp 15 and together with the clamping pipe clamp 15 increase the friction and resistance of the air duct and reduce the dragging force. In this way, the pseudo four-way connector of the staggered cross collision of the air duct can not only connect the internal air duct itself, but also strengthen the connection and fixing ability of the air duct from the outside.

[0030] like Figure 1 , Figure 2 and Figure 3When the air duct is connected with the air filter 1, a fixing bolt 3 is inserted into the air filter 1, and a fixing bolt 3 is inserted into the air filter 1. When the air duct is connected with the air filter 1, a fixing bolt 3 is inserted into the air filter 1, and a fixing bolt 3 is inserted into the air filter 1. When the air duct is connected with the air filter 1, a fixing bolt 3 is inserted into the air filter 1, and a fixing bolt 3 is inserted into the air filter 1.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, the fixed block 7 fixedly installed at the bottom of the upper bending tube seat 8 is engaged with the fixed slot 6 opened above the lower bending tube seat 5, and the fixed slot 6 is used in conjunction with the fixed block 7. The upper bending tube seat 8 and the lower bending tube seat 5 are conveniently connected through the fixed slot 6 and the fixed block 7, so that the air duct installed in the through groove of the lower bending tube seat 5 can be fixed, the clamping pipe hoop 15 is movably connected to the four-way body 1, and the damping reset rod 14 is symmetrically arranged with the central axis of the air duct opening 9. The clamping pipe hoop 15 on both sides can clamp and fix the air duct passing through the middle of the four-way body 1 from the outside of the four-way body 1.

[0032] The practical working principle of the present invention is as follows: first, take out the air duct that needs to be connected and installed, and directly open the closing plate 4 through the fixing bolts 3 to facilitate the connection and installation of the internal air duct, and insert one end of the air duct from the air duct opening 9 outside the four-way body 1, and let the air duct follow the direction of the groove inside the upper bent pipe seat 8 and directly enter the groove and exit, without the need for tedious operations such as bending and cutting the pipe up and down. The overall structure is simple and convenient for installation, and can also solve the problem of staggered cross collision of air ducts in a narrow space. Then, the air duct is sent out from the air duct opening 9 on the other side of the four-way body 1. The other air duct can be installed in the four-way body 1 according to the above operation, and then the upper bent pipe seat 8 and the lower bent pipe seat 5 are connected through the fixing slot 6 and the fixing block 7, so that the air duct installed in the through slot of the lower bent pipe seat 5 can be fixed, and then the anti-detachment pipe sleeve 16 can be set on the outside of the air duct, and the external clamping can be adjusted by the fixing slider 11 The position of the pipe clamp 15 is then tightened, and the positioning bolt 12 is then tightened to determine the current clamping pipe clamp 15, and then the damping reset rod 14 is pulled to shrink, so that the clamping pipe clamps 15 on both sides can clamp and fix the air ducts of different sizes passing through the middle of the four-way body 1 from the outside of the four-way body 1, and when facing the dragging of the air duct, the anti-drop pipe sleeve 16 that is larger than the clamping pipe clamp 15 will resist on one side of the clamping pipe clamp 15 and together with the clamping pipe clamp 15 increase the friction and resistance of the air duct and reduce the dragging force. In this way, the pseudo four-way connector of the staggered cross collision of the air duct is not only connected to the internal air duct itself, but also strengthens the connection and fixing ability of the air duct from the outside. In this way, the staggered cross collision connection of the air duct is installed, and finally, after completing the installation of all the air ducts according to the above operations, the device can be maintained daily, and the use process of the pseudo four-way connector for the staggered cross collision of the air duct is completed.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
