Detailed Description

The invention will be further illustrated with reference to the following examples:

directional terms used in this patent, such positional relationships are based on the orientation or positional relationship shown in fig. 1 and 5, 6, 7, are for convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present application.

Fig. 4 and 5 are schematic structural views of the quick coupling 1 and its inner clamping part; fig. 6 shows a test fitting 01 for testing the sealing of a component using the quick coupling 1. Two annular structures for clamping the quick structure are designed on the test connector 01, and the two annular structures are used for clamping two elastic pieces 11 of the quick connector 1, so that the quick connector is sealed. In the sealed test process of component tradition that uses quick-operation joint 1, need pass through quick-operation joint 1 interface is stopped up on the test connection 01 elder generation corresponding element, then lets in high pressure test gas through all the other pipeline imports, sees the atmospheric pressure transform in keeping a period, and atmospheric pressure is stable inconvenient, then proves that this component is airtight good, at this moment pulls down the component, needs will test connection 01 demolishs in step, at this moment will vigorously press quick-operation joint 1 thereby conveniently extract press button 12 test connection.

After the test is completed, the conventional way of handling is to use a sealing head 02 as shown in fig. 7 to seal off the pipeline component product using the quick connector 1, so as to prevent dust from entering the interior of the pipeline component. The upper part of the sealing head 02 is directly in a cylindrical shape and can be directly inserted into the middle of the two elastic sheets 11 of the quick connector 1, and the quick connector is plugged through a middle wafer. Due to the fact that no clamping mechanism is arranged, the quick connector can be conveniently plugged and pulled out, and the lower portion of an element of the quick connector is convenient to use.

In the embodiment shown in fig. 1 to 5, a novel sealing plug structure is used to replace the functions of both the test connection 01 and the sealing head 02. The quick connector screwing sealing plug is used on a quick connector 1, the structure of the quick connector 1 is shown in fig. 4 and 5, the quick connector 1 comprises elastic sheets 11 which are bilaterally symmetrical, the elastic sheets 11 are rhombic in the connector, pressing buttons 12 are symmetrically arranged on the front and the back of the elastic sheets 11, when the front and the back of the elastic sheets are pressed through the pressing buttons 12, the middle of each elastic sheet 11 is deformed, and the left and right distance between the middle of each elastic sheet 11 is increased; the quick coupling 1 is a conventional coupling which is commonly used in connection with urea pipes and will not be described in more detail here.

The quick-joint screwing sealing plug is shown in figures 1, 2 and 3 and comprises a circular sheet-shaped sealing sheet 2, wherein the upper part of the sealing sheet 2 is provided with a cylindrical insertion head 3; the lower part of the sealing piece 2 is provided with a vertical operating piece 4, the inserting head 3 is provided with a clamping block 31 which is convex corresponding to the quick coupling 1, when the sealing plug is inserted into the middle of the left and right elastic pieces 11 of the quick coupling 1, the clamping block 31 can penetrate through the middle of the left and right elastic pieces 11, and when the sealing plug is twisted, the clamping block 3 can be clamped in the middle of the elastic pieces 11. When the sealing plug is processed, the sealing sheet 2, the insertion head 3 and the operation sheet 4 are directly formed by integral injection molding by using a mold. The processing process is convenient and the cost is low.

The quick connector screwing sealing plug is mainly used in a urea pipe and used for keeping the interior of the urea pipe sealed, so that the interior of the urea pipe is kept clean in the assembly process of a diesel engine produced by a part manufacturer. This sealing plug needs to be used with a corresponding quick coupling 1 in the urea line, which sealing plug can be mounted and dismounted either by pressing the press knob 12 of the quick coupling 1 as in a conventional sealing plug. The position of the clamping block 31 on the insertion head 3 can be aligned, so that the clamping block 31 is directly inserted into the quick connector 1 from the middle of the left elastic sheet 11 and the right elastic sheet 11 of the quick connector 1, then the operation sheet 4 at the lower part of the handheld sealing sheet 2 controls the insertion head 3 and the clamping block 31 to rotate, the clamping block 31 is clamped into the middle position of the elastic sheet 11, the pipe orifice of the quick connector 1 is tightly attached to the sealing sheet 2, and locking and sealing are achieved. When the sealing plug needs to be detached, the operating sheet 4 rotates the latch on the insertion head 3, so that the latch 31 rotates to the front and rear positions, and the sealing plug can be conveniently pulled out.

Thus, when the pipeline element corresponding to the quick connector 1 is used, the sealing plug can be used in a sealing test and a subsequent process, and the sealing plug does not need to be replaced. This quick-operation joint spinner sealing plug simple structure processing is convenient, and is with low costs, use through the mode of rotatory locking simultaneously, the operation is faster, the installation is swift with the dismantlement, sealing requirement when not only can satisfying the test, can satisfy the swift requirement that the customer used simultaneously, the production corresponds the firm that has 1 pipeline part of quick-operation joint also need not design middle replacement step, holistic production efficiency has been improved greatly, the replacement process in the middle has been left out, greatly reduced manufacturing cost. Meanwhile, the product does not need to strongly press the pressing button 12 of the quick connector 1 for disassembly, so that the quick connector 1 is prevented from being damaged in the pressing process, and the yield of the product when reaching a user is guaranteed.

In a specific design, as shown in fig. 1, fig. 2 and fig. 3, the latching blocks 31 are respectively formed on the left and right sides of the insertion head 3, so that the latching blocks 31 can simultaneously clamp the elastic piece 11 portion of the quick connector 1 on both sides of the insertion head 3. The stress is more balanced, and the use effect is better. In a specific design, the latch 31 has a flat block shape. The edge of the fixture block 31 is processed into a circular arc shape. This makes it easier to insert the insertion head 3 with the latch 31 from the interface of the quick connector 1. Meanwhile, the arc shape of the edge of the clamping block 31 ensures that more acting points exist when the insertion head 3 is rotationally locked, and the sealing effect of the sealing sheet 2 is ensured.

In a specific design, as shown in fig. 1, 2 and 4, vertical edge strips 41 are formed on the front and rear sides of the lower portion of the operating plate 4, and an arc-shaped groove 42 is formed in the middle of the edge strip 41. The structural design enables the operation sheet 4 to bear larger torsion under the condition of using less materials, and the locking effect is ensured.
