Description

The utility model relates to the structure of a quick connector for pipe fittings, which is an improved structure for quick connection of pipes. It does not need other accessories or glue to cooperate, and completely depends on the special structure of the connector itself. Quickly complete the effect of firm connection of pipe fittings, and endow it with practical features.

Generally, there are many kinds and types of existing pipe joint structures, and the construction methods are different. For example, the more common plastic pipe joint operation is to use ordinary plastic pipe joints, apply plastic adhesive on the surface to be connected, and insert them directly into the sleeve It is very simple and quick to complete, but it is necessary to carry a can of plastic adhesive with the construction personnel during the operation and move it around the work site, and when the adhesive is insufficient, it must be replenished or replaced at any time, causing great trouble for the construction personnel. It is inconvenient, and the effect after the connection is not perfect. Often there will be gaps, leaks or even connection falls off after the event, which will greatly affect the use efficiency. Therefore, most of the more important pipelines use The operation method of metal pipes, and the general metal pipe connection, although it can enjoy better connection and use effect, but before the connection and during the operation, a set of cutting tools must be prepared at any time for each metal pipe end to be connected The male teeth are pre-machined, and the tape is wrapped around the male teeth at the pipe end to increase the tightness and anti-seepage performance between it and the female teeth on the inner edge of the metal joint, so as to achieve the purpose of connecting the metal pipes. The operation process of winding tape to seal and then screwing is not only extremely cumbersome but also requires the cooperation of multiple sets of auxiliary equipment. In terms of cost and working hours, it is difficult to meet the principle of excellent economic benefits; The rupture and leakage must be repaired and connected, but the water source cannot be temporarily closed. The operation method is the so-called running water connection pipe operation. In the past, most of them were treated with a set of expansion joints. In the state of no water at the end, and after connecting a suitable long pipe at the anhydrous end, use the two ends of the expansion joint to respectively fit the pipe fittings, and then tighten them with screws; press the rubber ring on the inner edge of the pipe fittings to be connected, It achieves a tight and stable connection effect, and the operation method of the running water connection pipe is something that cannot be achieved by ordinary plastic joints and metal joints in the past, but in terms of the price of expansion joints, it is much higher than ordinary joints, invisible It has a huge impact on its use efficiency.

The inventor is a worker who is engaged in the design and actual operation of this type of article. In view of the above-mentioned deficiencies, he has thought carefully and tried to study a simple and feasible joint structure to meet the needs of the actual situation. Based on his many years of work experience With continuous experimentation and improvement, an improved joint structure was finally successfully invented, which can meet the needs of many situations, and achieve the effect of simple, fast, economical and practical pipe fitting connection.

Therefore, the main purpose of the present utility model is to provide a quick connector structure for pipe fittings. With its simplified structure, it can be improved and installed without any other auxiliary equipment or plastic adhesive during construction work. The structure alone can To achieve the effect of connecting pipe fittings that are simple, fast and firmly combined.

The secondary purpose of the utility model is to make use of the arrangement of the annular accommodation tank, sliding ring, positioning ring and pressure hose of the utility model to pre-fill the pressure hose in the expansion space with supersaturated pressure, which can When the end of the connecting pipe fitting is inserted into the sleeve, it is only necessary to pull out the pin that locks the sliding ring, so that the pressure in the hose can be expanded and squeezed to support the outer peripheral edge of the connecting pipe fitting, and the sliding ring can be pushed to squeeze and position The ring teeth clamp the pipe fittings, easily complete the connecting process of the pipe fittings, and can be applied to the needs of various workplaces, with novel and practical features.

And the airtight snapping member group 2 is arranged at the inner edge position of the joint, and the backstop pushing member group 1 is arranged at the outer side edge position of the joint next to the airtight snapping member group 2, wherein: the backstop pushing member group 1 is connected by the horizontal tip 11 , locating ring block 12, pressure hose 13 and sliding ring 14, etc. The relative position of each component is that the horizontal tip 11 is set on the outside, and then the locating ring block 12, pressure hose 13 and sliding ring are arranged in sequence. Ring 14, etc., and the positioning ring block 12 is fixed in the outer ring groove of the inner edge of the joint with a C-shaped buckle 120, and two arc-shaped gaps are arranged on the outer periphery of the ring block, and a pair of wrench-shaped teeth 121 are arranged on the edge of the gap, and A perforation 122 is appropriately arranged on the positioning ring block 12, and the back inner edge of the positioning ring block 12 is set so that the opening faces inward.

Shaped groove structure, and the sliding ring 14 is an open groove outward Shaped structure, its groove is opposite to the groove on the back edge of the positioning ring block 12, forming a combined accommodating space for the placement of the pressure hose 13, and the pressure nozzle 131 of the pressure hose 13, Protrude out of the joint through the perforation 122, and on the periphery of the outer edge of the groove of the sliding ring 14, arc-shaped convex wings 141 with moderate width and length are correspondingly arranged, so that the two convex wings 141 can pass through the two arc-shaped gaps of the positioning ring block 12 It protrudes out, and at the same time, on both sides of the convex wing 141, there are correspondingly inversely toothed groove teeth 142, which can be locked in one direction by the swaying teeth 121 when the convex wing 141 protrudes through the gap in the outer periphery of the positioning ring block 12. The groove teeth 142 make the sliding ring 14 form a one-way moving body with a double-sided backstop structure; the airtight occlusal member group 2 is arranged on the inner part of the joint, and consists of a pair of pressing and clamping rings 21 and a soft hollow ring 22 , the extrusion ring 23 and the flexible ring valve 24 are combined. The relative position of each component is that the pressing and clamping ring 21 is next to the flat back edge of the sliding ring 14 of the backstop pushing member group 1, and then arranged in sequence It is a hollow ring 22, an extruding ring 23 and a flexible ring valve 24, etc., and the pressing and clamping ring 21 is a pair of double parallel []-shaped structures. When deformed by extrusion force transmission, there is an elastic space that can expand to the inner and outer edges for it to support the inner edge of the top head and the outer edge of the pipe to be connected, and the extrusion ring 23 is a set

Ring-shaped body, the top of which is a notch-shaped ring tooth 231, so when pushed by thrust, the ring tooth 231 can bend inward to the center due to the setting of the conical ring surface on the inner edge of the joint, forming a bite In the state of the pipe to be connected, in this way, when the airtight occlusal member group 2 passes through the push force of the reverse-stop push member group 1, it can bite and clamp the pipe to be connected by pressing and deforming the clamp ring 21 and the extrusion ring 23 , and the soft hollow ring 22 between the pressing and clamping ring 21 and the extruding ring 23, due to its own material relationship, while being pressed and transmitted, the shape is deformed from a circular tube to a flat shape under pressure, which is fully packed. The gap between the joint and the pipe to be connected, and the flexible ring valve 24 at the innermost edge of the joint, when the pipe to be connected is inserted, is affected by the friction of the outer wall of the front end of the pipe to be connected, causing the leading edge of the ball ring to bend inward, like a snowball The more the ground is rolled, the bigger it is, that is to say, once the connecting pipe is inserted into the joint, a seepage-proof and leak-proof feature can be produced by the flexible ring valve 24, and then set with the soft hollow ring 22 to achieve the effect of double-layer complete sealing and anti-seepage; the overall structure is combined and set , before the above-mentioned sets of components are set up and not pressurized, the airtight occlusal component group 2 can be set on the inner edge of the joint, and the outer edge can then be provided with the backstop pushing component group 1, or a set of concave can be added to the outermost edge of the components. The ring cover 15 increases the trimming and appearance of the outer edge, and inserts the horizontal tip 11 from the outward joint, and engages the positioning groove 143 on the front edge of the convex wing 141 of the fixed sliding ring 14, so that the sliding ring 14 remains fixed and cannot be displaced. The pressure nozzle 131 protruding from the perforation 122 is filled with pressure so that the pressure hose 13 is filled with supersaturated pressure. The pressure can be applied according to the actual situation. Fixed inside the joint, the sliding ring 14 is inserted and fixed by the horizontal pin 11, so the pressure hose 13 cannot be stretched in the accommodation space formed by the positioning ring block 12 and the sliding ring 14; As shown in Figure 4, the horizontal pin 11 is pulled out from the joint, so that the sliding ring 14 loses the clamping of the horizontal pin 11 and can slide backwards, while the supersaturated pressure in the pressure hose 13 does not move when the positioning ring block 12 And under the movable state of the sliding ring 14, the sliding ring 14 must be pushed as far as possible by its pressure, so that it produces a state of pushing backwards, and the reverse tooth-shaped groove teeth 142 on the convex wings 141 also move backwards successively. Move its one-way engagement position with the swaying teeth 121 of the positioning ring block 12, that is, after the sliding ring 14 moves backward and pushes the airtight occlusal component group 2, it cannot be restored to its original state without being removed, but if the C-shaped buckle 120 Take off the clamped state of the release positioning ring block 12 and the joint, then the entire backstop push member group 1 can be removed to achieve the reversible characteristics of preventing improper operation. The merging clamp ring 21 is pressed and deformed by force transmission to extrude the soft hollow ring 22, so that the section of the merging clamp ring 21 expands on both sides to squeeze the joint and the pipe to be connected. Close the gap between the joint and the pipe to be connected, and the extrusion ring 23 behind the hollow ring 22 also bears the extrusion force of moving forward and backward, so that the teeth of the ring gear 231 bend and occlude to the pipe to be connected, and the greater the pressure The better the occlusal effect, it can occlude the connecting pipe fittings very firmly, and complete the simple and rapid connection process of the joints, as shown in Figure 5. In addition, after the connecting pipe is inserted into the joint, the ball ring at the front edge of the flexible ring valve 24 is crimped. In the closed state, there is absolutely no risk of gaps or loosening and falling, achieving the effect of stable tight connection and reversible characteristics.

The connection of the article of the utility model, after the connecting pipe is fitted to the joint, only needs to pull out the horizontal tip 11 to complete the whole connection process, which can save about 90% of the construction time of the traditional construction method, and no auxiliary equipment is required in the process , zero material or glue, easy and fast to achieve the purpose and effect of connection, and its reversible characteristics can prevent the loss of improper operation, it is a product improvement structure with great novelty and practical value.
