Description

Waterproof anti-off type bellows connector

technical field

The utility model relates to a bellows connecting piece, in particular to a connecting piece which can prevent water leakage and disengagement at the joint of the bellows.

Background technique

At present, there are 3 methods specially used for bellows connectors on the market: clamp-type connector connection, sleeve connection and socket connection after the pipe itself is flared. These three connection methods have their own shortcomings: although the clamp-type connector can prevent the connected pipe from being disengaged, its semicircular structure cannot prevent water seepage or leakage at the connection; sleeve connection and pipe flare socket Although the connection and matching sealing ring can prevent water leakage, it cannot avoid the situation that the connection is disengaged due to improper construction or later geological subsidence.

Contents of the invention

In order to overcome the problem that the current connectors or connecting mechanisms cannot prevent water leakage and disengagement at the joints of corrugated pipes at the same time, the purpose of this utility model is to provide a waterproof and detachable corrugated pipe connector, which can prevent the pipe from connecting It can prevent water leakage at the joints, and can prevent the joints from being disengaged, and the installation is quick and convenient.

The technical solution adopted by the utility model to solve the technical problem is: the waterproof and anti-off type bellows connector, which is characterized in that it is composed of a sleeve with a pin hole, a pin and an "O"-shaped sealing ring, and the pin is composed of Composed of a pin cap and a wedge-shaped barb, the upper part of the wedge-shaped barb is connected with a pin cap, and the "O"-shaped sealing ring is inserted into the trough at the end of the two adjacent bellows to be connected, and the "O"-shaped The ends of the two adjacent bellows of the sealing ring are respectively inserted into the two ends of the sleeve with the pin hole, the wedge-shaped barb of the pin passes through the pin hole and the wedge-shaped barb is inserted into the bellows that has been inserted into the sleeve In the wave trough, the pin cap of the pin is located outside the outer wall of the sleeve, and the sleeve and two adjacent bellows are fixed by pins to prevent the two from being disengaged.

The pin is cylindrical, the upper part is a pin cap, and the lower part is connected with two symmetrically distributed wedge-shaped barbs. The two wedge-shaped barbs can be hooked on the inner wall of the sleeve to prevent the pin from detaching from the sleeve.

The outer shape of the sleeve is cylindrical, and 2-4 pin holes are uniformly distributed along the circumferential direction on the wall at both ends of the sleeve.

The beneficial effect of the utility model is that it not only prevents water leakage after the bellows is connected, but also prevents the disconnection of the connection.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in the accompanying drawings, the waterproof and anti-off type bellows connector described in the utility model is characterized in that it is composed of a sleeve 1 with a pin hole 2, a pin 3 and an "O"-shaped sealing ring 6, and the pin 3 It consists of a pin cap 4 and a wedge-shaped barb 5. The upper part of the wedge-shaped barb 5 is connected to the pin cap 4. The "O"-shaped sealing ring 6 is inserted into the trough at the end of two adjacent bellows 7 to be connected. Insert the ends of two adjacent bellows that have been covered with "O"-shaped sealing rings 6 into the two ends of the sleeve 1 with the pin hole 2 respectively, pass the wedge-shaped barb 5 of the pin 3 through the pin hole 2 and The wedge-shaped barb 5 is correspondingly inserted into the trough of the bellows 7 that has been inserted into the sleeve 1, the pin cap 4 of the pin 3 is located outside the outer wall of the sleeve 1, and the sleeve 1 passes through the two adjacent bellows 7. Pin 3 is fixed to prevent the two from being disengaged.

In Fig. 2: the pin 3 is cylindrical, the upper part is a pin cap 4, and the lower part has two symmetrically distributed wedge-shaped barbs 5.

The implementation process is as follows:

When implementing the connection, first put the "O" type sealing ring 6 into the first trough at the end of the bellows 7, and then insert the end of the bellows 7 into the cylindrical sleeve with a hole to a depth of about half, so that the sleeve 1 The pin hole 2 on the top is facing a trough of the bellows 7, and the lower half of the pin 3 is inserted into the corresponding trough on the bellows 7 through the pin hole 2 on the sleeve 1, as shown in Figure 5; the pin cap 4 stay on the outer wall of the sleeve 1, and the two wedge-shaped barbs 5 of the pin 3 are hooked on the inner wall of the sleeve 1 to prevent the pin 3 from detaching from the sleeve 1, as shown in Figure 4; the other pin on the sleeve 1 is the same Hole 2 is loaded with pin 3.

Install another section of bellows according to the above steps. As shown in Figure 5, the bellows has been connected. In the figure, the "O" type sealing ring 6 plays the role of preventing water leakage at the joint; the pin 3 is fixed on the sleeve 1 through the pin cap 4 and the wedge-shaped barb 5, and the sleeve 1 and bellows 7 are fixed by pin 3 to prevent the two from being disengaged.
