Description

Technical Field

[0001] The present invention relates to the technical field of pipeline fitting manufacturing, and more specifically, to a novel quick groove connector. Background Art

[0002] Currently, there are generally two ways to control the groove size of quick-release joints: the first is to use a concentric circle or eccentric circle design and control the size through the arc radius; the second is to use an ellipse design and control the size through the major axis and minor axis of the ellipse. The use of concentric circles and uneven inner cavity compression design of ellipses will cause excessive compression of the rubber ring, prone to rubber fatigue, reduce the elastic life of the rubber ring, and increase the leakage probability of the rubber ring.

[0003] The support in the middle of the housing usually adopts a single bevel design. During the bolt tightening process of the product, when the groove diameter exceeds the limit size, it is easy to cause an increase in the bolt shear force. Without disassembling the nut, the gap between the housing and the housing cannot be adjusted during installation, thus reducing the installation efficiency.

[0004] Most of the top of the outer shape adopts a semi-circular flat top design, which is prone to concentrated bending moment stress. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a novel quick groove connector aiming at the above deficiencies, achieving the purposes of torque balance on both sides of the joint, small bolt shear force, high bending moment capacity, simple operation, and high working efficiency.

[0006] To solve the above technical problem, the technical solution of the present invention is: a novel quick groove connector, including two connector bodies, and bolt heads are respectively provided at both ends of the connector body. It is characterized in that: connection devices are respectively provided between the connector body and the bolt heads at both ends.

[0007] An optimized scheme is that the connection device includes a male angle provided on one side of the connector body and a female angle provided on the other side of the connector body;

[0008] The male angles and female angles at both ends of the connector body are arranged corresponding to the central axis of the connector body, and the shapes of the male angles and female angles correspond to each other.

[0009] An optimized scheme is that a support block is provided on the connector body between the male angle and the female angle. The upper surface of the support block has an included angle with the central axis of the connector body. The inclination directions of the support blocks at both ends of the connector body are opposite and the two included angles are complementary.

[0010] An optimized scheme is that the bolt head at one end or both ends of the connector body is provided with an opening.

[0011] An optimized scheme is that a counterbore for preventing the nut from moving is provided at the opening.

[0012] An optimized solution is that two card slots are provided on both sides of the inner cavity of the connector body. The surface of the card slot is in the shape of a polyline composed of multiple continuous arcs and straight lines, and the two ends of the card slot are straight lines tangent to the adjacent arcs.

[0013] An optimized solution is that the outer surface of the connector body is semi-circular spherical.

[0014] The present invention adopts the above technical solutions. Compared with the prior art, it has the following advantages: When in use, the male angle and the female angle are combined yin and yang, which can balance the torque on both sides of the connecting device, reduce the shear force of the bolts, have good sealing performance and high assembly accuracy; the support block can adjust the middle gap at the joint of the two connector body joints, adjust the perimeter after the two connector bodies are combined, and adjust the pre-tightening force of the bolts at the end of the joint. The structural design is reasonable; the two connector bodies are fitted with card slots, and the size is controlled by the perimeter; a sunk groove for preventing the nut from moving is provided at the opening, so that the two connector bodies can be more conveniently and quickly installed; the outer part of the connector body adopts a semi-circular spherical design, and the surface is semi-circular spherical, which can improve the bending moment capacity during use; the operation is simple when in use, and the work efficiency is greatly improved.

[0023] The present invention will be described in detail below with reference to the accompanying drawings.

[0024] Example 1, as shown in the attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 A new type of fast groove connector, as shown in the figure, includes two connector bodies 6. One end of the connector body 6 is provided with a first bolt head 4, and the other end is provided with a second bolt head 5. Connection devices are respectively arranged between the connector body 6 and the first bolt head 4 and the second bolt head 5. The connection device includes a male angle 1 arranged on one side of the connector body 6 and a female angle 2 arranged on the other side of the connector body 6. The male angles 1 and female angles 2 at both ends of the connector body 6 are arranged corresponding to the central axis of the connector body 6 and the shapes of the male angles 1 and female angles 2 correspond to each other. A support block 3 is arranged on the connector body 6 between the male angle 1 and the female angle 2. The upper surface of the support block 3 has an included angle with the central axis of the connector body 6. The inclination directions of the support blocks 3 at both ends of the connector body 6 are opposite and the two included angles are complementary.

[0025] When in use, the male angle 1 and the female angle 2 are in male-female cooperation, which can balance the torque on both sides of the connection device, reduce the shear force of the bolts, and have good sealing performance. The support block 3 can adjust the intermediate gap at the joint of the two connector bodies, adjust the perimeter after the two connector bodies are fitted, and adjust the pre-tightening force of the bolts at the end of the joint.

[0026] The first bolt head 4 is provided with an opening 9, and a counterbore 10 for preventing the nut from moving is arranged at the opening 9. The second bolt head 5 can also be provided with an opening, which is not drawn in this embodiment. Those skilled in the art should clearly understand that this can more conveniently and quickly install the two connector bodies 6.

[0027] The inner cavity of the connector body 6 is provided with two card slots 7. The card slots 7 are arranged on both sides of the connector body 6. The surface of the card slot 7 adopts a multi-segment line design, which is a multi-segment line shape composed of a plurality of continuous arcs and straight lines. The two ends of the card slot 7 are straight lines 11 tangent to the adjacent arcs. The two connector bodies 6 are fitted with the card slots 7, and the size is controlled by the perimeter of the multi-segment line.

[0028] The outside 8 of the connector body adopts a semi-circular spherical design, and the surface is semi-circular spherical, which can improve the bending moment capacity during use.

[0029] When in use, the rubber ring is installed in the two pieces of connector body 6, and the first bolt head 4 and the second bolt head 5 are inserted into the bolts and tightened with nuts. The first bolt head 4 is provided with an opening 9, or it can be not opened like the second bolt head 5. The opening 9 can be understood as: the distance between the bolt and the nut can be adjusted more quickly, the bolt rod can be quickly removed from the sink 10, the installation gap between the two shells can be increased more quickly, and the pipe joint can be more easily inserted into the rubber ring and the shell. When installing, the shell and the rubber ring are inserted into the end of the pipe together, and the other part is inserted into the end of the other pipe. At this time, a ring-shaped shell is formed and embedded in the grooves of the two pipes. There are bolts and nuts at the bolt heads at both ends of the connector body 6. Tighten the nuts in turn and fix the nuts in the sink 10 to prevent the nuts from falling out by themselves. Adjust the body gap of the connector according to the pipe diameter.

[0030] This new type of quick groove connector can better adapt to multiple pressures such as axial pressure, angular deflection and rotation angle between the pipe connection ends, and can well adapt to the expansion, contraction and deflection angle between the pipes. It can ensure that the pipes can work under high pressure for a long time and prevent the two ends of the pipes from separating due to various excessive pressures. At the same time, this new type of quick installation groove connector is easy to operate and greatly improves work efficiency. This utility model patent is applicable to all groove connection methods.

[0031] The above is an example of the best implementation of the present invention, and the parts not described in detail are common knowledge of ordinary technicians in the field. The protection scope of the present invention shall be based on the content of the claims, and any equivalent transformation based on the technical enlightenment of the present invention is also within the protection scope of the present invention.
