Description

Technical Field

[0001] The invention relates to the technical field of trachea, in particular to a trachea quick-connecting device. Background Art

[0002] Cutting torches are widely used in steel structure production, shipbuilding and other operations. The cutting torch belt is generally a rubber tube. Straight-through joints are often used for gas pipe extension and repair. The function of the cutting torch is to mix oxygen and acetylene in proportion to form a preheating flame, and spray high-pressure pure oxygen onto the workpiece to be cut, so that the cut metal burns in the oxygen jet, and the oxygen jet blows away the slag (oxide) generated by the combustion to form a cutting seam. The cutting torch is the main tool for gas cutting workpieces. The cutting torch is divided into two types: injection and suction type and isobaric type according to the different mixing methods of oxygen and acetylene in the preheating flame. Among them, the injection and suction type cutting torch is the most commonly used. Cutting torches are divided into ordinary cutting torches, heavy-duty cutting torches, and welding and cutting torches according to their uses. Gas pipe joints have a series of advantages such as advanced structure, good performance, easy use, no welding, and no need to expand the pipes. Therefore, ferrule-type pipe joints have been widely used in the hydraulic and pneumatic systems of various types of machinery. Joints are generally divided into two types, plastic joints and metal joints. Plastic joints have lower production costs and simpler manufacturing processes. At the same time, the pressure resistance is only 1 MPa. Metal joints are more expensive due to their complex manufacturing processes and high requirements for materials. Metal joints are resistant to pressure and high temperature, and are the first choice for use in some high-demand environments.

[0003] The insertion depth of traditional quick connectors is difficult to control during actual use, and the insertion depth of the air pipes on both sides is not equal. During use, pulling the air pipe can easily cause the shorter inserted side to loosen and leak, ultimately leading to an accident. Summary of the invention

[0004] The purpose of the present invention is to solve or at least alleviate the problems existing in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a trachea quick connection device, comprising a connecting mechanism and a trachea assembly, the connecting mechanism comprising a connecting assembly, and a symmetrically arranged mounting assembly is installed on the connecting assembly, the connecting assembly comprises a connecting pipe, and the two ends of the connecting pipe are conical structures, a mounting ring is fixedly connected at the midpoint of the connecting pipe, the mounting assembly comprises a mounting sleeve fixedly connected to the mounting ring, and the outer wall of the mounting sleeve is provided with two symmetrical arc-shaped openings, the inner walls of the two arc-shaped openings are both installed with adjustment assemblies, and the inner wall of the mounting sleeve is provided with two arc-shaped plates driven by the adjustment assemblies, and the outer walls of the opposite sides of the two arc-shaped plates are fixedly connected with multiple protrusions.

[0006] By adopting the above structure, the connection mechanism is provided to facilitate the quick and stable connection of two tracheal components.

Two symmetrically arranged adjustment plates are fixedly connected to the outer wall of the top of the driving seat.

[0010] By adopting the above structure, the adjustment plates are provided to facilitate pulling the driving seat to move.

The rotating rollers are rotatably installed on the two adjustment plates.

[0012] By adopting the above structure, the rotation of the cam drives the rotating roller to rotate in the annular groove. The rotation of the cam is convenient to directly drive the adjustment plate to lift, and when the adjustment plate lifts, it directly drives the arc-shaped plate to move.

When the worm rotates, it directly drives the rotation of two cams through the worm wheel, thereby facilitating the adjustment of the position of the arc plate. Moreover, the cooperation between the worm and the worm wheel has a self-locking function, thus ensuring the stable pressing of the arc plate.

[0015] In a possible implementation manner, two symmetrically arranged arc-shaped grooves are formed on the outer wall of one side of the mounting sleeve, and limiting grooves are formed on the inner walls of one sides of the two arc-shaped grooves.

A protective pad is fixedly connected to the bottom outer wall of the sliding plate. Three springs are fixedly connected between the sliding plate and the inner wall of the groove.

[0022] By adopting the above structure, the spring is compressed by the sliding seat, which facilitates the reverse pressing of the auxiliary sleeve. The arrangement of the protective pad facilitates the protection of the auxiliary sleeve.

[0023] In a possible implementation manner, the pressing component includes a fixed seat fixedly connected to the inner wall of the mounting groove, and a rubber pad is fixedly connected to the bottom outer wall of the fixed seat.

[0035] Embodiment 2 Based on Embodiment 1, this embodiment introduces the specific structure of the pressing component 24 in a trachea quick-connection device. Figure 9 As shown, the pressing component 24 includes a fixed seat 33 fixedly connected to the inner wall of the installation groove, and a rubber pad 34 is fixedly connected to the bottom outer wall of the fixed seat 33.

[0036] Working principle: During installation, first sleeve the trachea 22 on the outer wall of the connecting pipe 5. When one end of the trachea 22 abuts against the mounting ring 6, then rotate the rotating part 21. When the rotating part 21 rotates, it directly drives the worm 20 to rotate. The rotation of the worm 20 directly drives the two cams 17 to rotate through the worm gear 19. When the cams 17 rotate, the rotating rollers 27 rotate in the annular groove 26, and then it is convenient to cooperate with the adjusting plate 18 to directly pull the driving seat 14 to slide in the adjusting seat 12. When the driving seat 14 drives the connecting plate 15 to push the arc plate 11 to press the trachea 22, first rotate the auxiliary sleeve 23 before pressing the trachea 22. When the auxiliary sleeve 23 rotates, it directly drives the limit block 25 to insert into the limit groove 9. At this time, the auxiliary sleeve 23 and the installation sleeve 7 are engaged with each other. When the auxiliary sleeve 23 and the installation sleeve 7 come into contact, the pressing component 24 is squeezed. During the squeezing, the sliding plate 31 compresses the spring 30 in the groove 29, thereby improving the stability of the connection of the auxiliary sleeve 23, or stably connecting the auxiliary sleeve 23 through the rubber pad 34 on the fixed seat 33.
