Description

Technical Field

[0001] The utility model relates to the field of pipeline connection, in particular to an integrated double-clamping stainless steel elbow. Background Art

[0002] For the sake of human health and to prevent drinking water from being contaminated by pipelines, stainless steel pipes and pipe fittings are becoming more and more popular. Among them, stainless steel double-clamp pipe fittings have good pipe fittings compatibility, convenient and quick construction, superior economic performance, and strong earthquake-resistant connections. Double-clamp pipes make full use of the effective rigidity of metal materials. At the connection between pipes and fittings, both ends are crimped with calipers to achieve double-sided fixation, compressed into two hexagons, and fully anti-locking, thereby greatly improving their pull-out resistance and rotation resistance.

[0003] In the prior art, when installing pipelines, the distribution of pipelines is relatively complex, and it is inevitable that the pipelines will turn or two pipelines will cross. In this case, we need an integrated double-clamped stainless steel elbow.

[0004] At present, when fixing the one-piece double-clip stainless steel elbow, a thin-walled steel pipe is usually inserted into the double-clip stainless steel elbow, and then the connection between the thin-walled steel pipe and the stainless steel elbow is placed inside the caliper for crimping. However, in actual use, the stainless steel elbow needs to be fixed immediately after each connection with the thin-walled steel pipe. It is impossible to connect the thin-walled steel pipe and the stainless steel elbow and then crimp and fix them at the same time. In addition, there are certain requirements for the depth of the thin-walled steel pipe inserted into the stainless steel elbow. The current equipment can only rely on construction personnel to measure and draw lines in advance and then plug in, and the connection efficiency is low. Therefore, an one-piece double-clip stainless steel elbow is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an integrated double-clip stainless steel elbow, which aims to improve the problems in the prior art that a steel pipe needs to be crimped and fixed one by one, the insertion depth needs to be measured and marked in advance, and the connection efficiency is low.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an integrated double-clamped stainless steel elbow, including a steel pipe elbow, a sealing groove is opened inside the steel pipe elbow, a sealing rubber ring is clamped inside the sealing groove, a fixed ring is fixedly connected inside the steel pipe elbow, a limiting ring is fixedly connected to the front of the fixed ring, a T-slot is opened inside the fixed ring, an elastic component is fixedly connected inside the T-slot, a clamping block is fixedly connected to the outside of the elastic component, a friction groove is opened on the outside of the clamping block, and a sliding groove is opened inside the limiting ring.

[0007] As a further description of the above technical solution:

[0008] The outer circumference of the steel pipe elbow is fixedly connected with a fixed round block, and the fixed round blocks are provided in two groups, and the two groups of fixed round blocks are connected by a support rod.

[0009] As a further description of the above technical solution:

[0010] The elastic component comprises a limit spring, the bottom end of which is fixedly connected to the inner wall of the bottom end of the T-slot, the top end of which is fixedly connected to a T-block, and the outer side of the T-block is fixed to the inner side of the clamping block.

[0011] As a further description of the above technical solution:

[0012] The outer periphery of the T-block is slidably connected inside the T-slot.

[0013] As a further description of the above technical solution:

[0019] The utility model has the following beneficial effects:

[0020] 1. In the utility model, by setting a fixed ring, a limit ring and a limit spring, after the thin-walled steel pipe is inserted into the steel pipe elbow, the insertion depth of the thin-walled steel pipe is limited by the fixed ring, and the clamping block fixes the thin-walled steel pipe at the same time, so that all the steel pipe elbows and thin-walled steel pipes that need to be connected can be connected and crimped uniformly, thereby improving the connection efficiency and being more convenient to operate.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 3 The utility model provides an embodiment: an integrated double-clipped stainless steel elbow, including a steel pipe elbow 1, the two ends of the steel pipe elbow 1 are bent at ninety degrees, a sealing groove 2 is opened inside the steel pipe elbow 1, and two groups of sealing grooves 2 are arranged, which are symmetrically arranged at the two ends of the steel pipe elbow 1, and a sealing rubber ring 3 is clamped inside the sealing groove 2, and the inner side of the sealing rubber ring 3 protrudes from the inner opening of the sealing groove 2 and will not fall out from the inside of the sealing groove 2. When the thin-walled steel pipe is inserted from the inside of the steel pipe elbow 1, the sealing rubber ring 3 will contact the outer wall of the thin-walled steel pipe to provide good sealing performance. A fixed circular ring 4 is fixedly connected inside the steel pipe elbow 1 to play a fixed supporting role. When the thin-walled steel pipe is inserted into the inside of the steel pipe elbow 1, it will be blocked by the fixed circular ring 4 and cannot be inserted. Here is the standard depth of the designed steel pipe insertion, and the fixed circular ring 4 is fixedly connected to the limiting circular ring 5 on the front side, and a T-slot 6 is opened inside the fixed circular ring 4. There are multiple groups of T-slots 6, which are evenly distributed in the inside of the fixed circular ring 4.

[0030] Reference Figure 3-Figure 4, an elastic component is fixedly connected inside the T-slot 6, and the elastic component includes a limit spring 7. The bottom end of the limit spring 7 is fixedly connected to the inner wall of the bottom end of the T-slot 6, and the top of the limit spring 7 is fixedly connected to a T-block 8. When the T-block 8 is not subjected to force, the limit spring 7 will push the T-block 8 to move upward, and the outer periphery of the T-block 8 is slidably connected to the inside of the T-slot 6. The inner wall of the T-slot 6 limits the T-block 8 to move up and down only along the inner wall of the T-slot 6. A clamping block 9 is fixedly connected to the outside of the elastic component. The outer side of the clamping block 9 contacts the inner wall of the steel pipe elbow 1, and the front of the clamping block 9 is provided with an inclined surface. When the clamp When the front side of the holding block 9 is subjected to a backward force, the inclined surface on the front side of the clamping block 9 can convert part of the force into a force toward the center of the limiting ring 5. The outer side of the T-block 8 is fixed to the inner side of the clamping block 9. The outer side of the clamping block 9 is provided with a friction groove 10 for increasing the friction force of the clamping block 9. The inside of the limiting ring 5 is provided with a sliding groove 11. There are multiple groups of sliding grooves 11, which are distributed in an annular manner inside the limiting ring 5, and the position of each group of sliding grooves 11 corresponds to a group of clamping blocks 9. The outer periphery of the clamping block 9 is slidably connected to the inside of the sliding groove 11, and the sliding groove 11 limits the clamping block 9 to slide only along the inner wall of the sliding groove 11.

[0031] Reference Figure 1 A fixed round block 12 is fixedly connected to the outer periphery of the steel pipe elbow 1. Two groups of fixed round blocks 12 are provided, which are respectively fixedly connected to the two ends of the steel pipe elbow 1. The two groups of fixed round blocks 12 are connected by a support rod 13. Two groups of support rods 13 are provided, which are symmetrically arranged on the upper and lower sides of the fixed round blocks 12 to provide support for the steel pipe elbow 1.

[0032] Working principle: when you want to quickly connect the steel pipe elbow 1 and the thin-walled steel pipe, first insert a thin-walled steel pipe of an appropriate model into the interior of the steel pipe elbow 1. When the thin-walled steel pipe contacts the clamping block 9, continue to push the thin-walled steel pipe into the interior of the steel pipe elbow 1. The inclined surface of the clamping block 9 will convert part of the force of the thin-walled steel pipe into a circular force toward the limiting ring 5. At this time, the clamping block 9 will move along the sliding groove 11 toward the center of the limiting ring 5. The clamping block 9 drives the T-block 8 to move inward along the T-slot 6, compressing the limiting spring 7. The limiting spring 7 generates elastic force to make the clamping block 9 have a force to move outward, thereby providing a clamping force to clamp the thin-walled steel pipe. At the same time, when the thin-walled steel pipe contacts the fixed ring 4, the thin-walled steel pipe cannot continue to move forward. At this time, the depth meets the standard. The clamping block 9 fixes the thin-walled steel pipe, and then all the thin-walled steel pipes and steel pipe elbows 1 that need to be connected are connected, and then clamped uniformly, thereby improving the connection efficiency. When the steel pipe elbow 1 is subjected to pressure, the pressure will be transmitted from the fixed round block 12 to the support rod 13, and the support rod 13 provides oblique support force, so that the steel pipe elbow 1 will not be deformed by external force, resulting in a change in the bending angle, thereby ensuring the quality and service life of the steel pipe elbow 1.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
