Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a flange that can be quickly connected. Background Art

[0002] A flange is a connection tool. A flange connection refers to a detachable connection consisting of a flange, gasket, and bolts interconnected as a combined sealing structure. Flanges are categorized as threaded (threaded) flanges, welded flanges, and clamp flanges. Flange connections are widely used in the construction industry, urban water supply, boiler pressure vessels, petroleum industry, gas supply, chemical industry, food industry, fire protection, pharmaceutical industry, power plants, water conservancy, HVAC, and other industries due to their advantages such as good sealing performance, stable structure, high strength, ease of use, and low cost.

[0003] After searching, the applicant discovered a Chinese patent application titled "A Flange with a Quick Connection Effect," with publication number "CN219510354U." This patent primarily utilizes a clamping plate, a connecting rod, and a stop bolt to limit the position of two flanges and prevent them from moving. The stop bolt, through a stop ring and thread, can re-tighten the two flanges, thereby improving the stability of the connection.

[0004] The above device can achieve the purpose of limiting the two flanges and then tightening them with bolts to improve the stability of the connection through the setting of a series of structures. However, when the above device is actually used, it is necessary to first align the threaded holes on the two flanges and then fix them with a clamping plate. However, the flanges are generally circular and are prone to rolling after the threaded holes are aligned, which can easily cause the aligned threaded holes to be misaligned, making it more difficult to bolt the two flanges. Utility Model Content

[0005] The purpose of the present invention is to provide a quick-connect flange to solve the problem in the background art that the two flanges may be misaligned due to positional deviation of the threaded holes, which may cause difficulty in flange connection.

[0007] Preferably, the positioning assembly includes a positioning ring, one side of which is fixedly connected to a side of the first flange away from the connecting pipe, and the interior of the positioning ring is provided with positioning cavities having the same number as the threaded holes.

[0008] Preferably, the positioning assembly further comprises a plurality of positioning blocks, surfaces of the plurality of positioning blocks are all slidably connected to the inner walls of the corresponding positioning cavities, and the plurality of positioning blocks are all trapezoidal.

[0009] Preferably, the positioning assembly further comprises a plurality of springs, one end of each of the springs being fixedly connected to one end of the corresponding positioning block, and one end of each of the springs away from the corresponding positioning block being fixedly connected to one side of the inner wall of the corresponding positioning cavity.

[0010] Preferably, the positioning assembly also includes a mounting ring, one side of the mounting ring is fixedly connected to one side of the second flange, the inner wall of the mounting ring is provided with a plurality of sliding grooves, the inner wall of the mounting ring is provided with a plurality of positioning grooves, and the number and position of the plurality of positioning grooves correspond to the threaded holes.

[0011] Preferably, the limiting assembly includes multiple groups of limiting grooves, each group of limiting grooves has two limiting grooves, the two limiting grooves are respectively opened on the opposite side of the inner wall of the corresponding positioning cavity, the inner walls of the two limiting grooves are slidably connected to the limiting blocks, and the opposite sides of the two limiting blocks are fixedly connected to the opposite sides of the corresponding positioning blocks.

[0012] Preferably, a sealing ring is fixedly connected to a surface of the second flange close to the mounting ring, and inner walls of a plurality of threaded holes on the first flange and the second flange are both threadedly connected with bolts.

[0013] Preferably, the outer wall of the positioning ring and the inner wall of the mounting ring have the same diameter.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides Figure 1-Figure 5 The quick-connect flange shown includes a first flange 1 and a second flange 4, and a plurality of threaded holes 6 are provided on one side of the first flange 1 and the second flange 4. The first flange 1 and the second flange 4 are jointly provided with a positioning component 2 that can ensure that the threaded holes 6 on the first flange 1 and the second flange 4 are in facing positions. The first flange 1 is provided with a limiting component 3 that can limit the positioning component 2. The opposite sides of the first flange 1 and the second flange 4 are fixedly connected with a connecting pipe 5. The first flange 1 and the second flange 4 are positioned and pre-fixed by the positioning component 2, so that the threaded holes 6 on the first flange 1 and the second flange 4 can be in relative positions, thereby avoiding the problem that the first flange 1 and the second flange 4 roll before connection, causing the threaded holes 6 to be staggered and affecting the connection using bolts 7, so that the first flange 1 and the second flange 4 can be quickly connected.

[0025] like Figure 2-Figure 5 As shown, the positioning assembly 2 includes a positioning ring 201, one side of the positioning ring 201 is fixedly connected to the side of the first flange 1 away from the connecting pipe 5, and the interior of the positioning ring 201 is provided with a positioning cavity 206 with the same number as the threaded holes 6. The positioning assembly 2 also includes a plurality of positioning blocks 202, and the surfaces of the plurality of positioning blocks 202 are all slidably connected to the inner walls of the corresponding positioning cavities 206. The plurality of positioning blocks 202 are all trapezoidal. The positioning assembly 2 also includes a plurality of springs 207, one end of the plurality of springs 207 is fixedly connected to one end of the corresponding positioning block 202, and the ends of the plurality of springs 207 away from the corresponding positioning block 202 are all slidably connected to the inner walls of the corresponding positioning cavities 206. One side is fixedly connected, and the positioning assembly 2 also includes a mounting ring 204, one side of the mounting ring 204 is fixedly connected to one side of the second flange 4, and the inner wall of the mounting ring 204 is provided with a plurality of slide grooves 205, and the inner wall of the mounting ring 204 is provided with a plurality of positioning grooves 203. The depth of the plurality of positioning grooves 203 is greater than the length of the plurality of positioning blocks 202, which can facilitate the later fastening of the first flange 1 and the second flange 4 by bolts 7. The number and position of the plurality of positioning grooves 203 correspond to the threaded holes 6, so that they can cooperate with the corresponding positioning blocks 202 to fix the position between the first flange 1 and the second flange 4.

[0026] like Figure 5 As shown, the limit assembly 3 includes multiple groups of limit grooves 301, and each group of limit grooves 301 has two limit grooves. The two limit grooves 301 are respectively opened on the opposite side of the inner wall of the corresponding positioning cavity 206. The inner walls of the two limit grooves 301 are slidingly connected to the limit blocks 302. The setting of the limit blocks 302 and the limit grooves 301 can make the positioning block 202 more stable when moving. The opposite sides of the two limit blocks 302 are fixedly connected to the opposite sides of the corresponding positioning blocks 202.

[0027] like Figure 2-Figure 4 As shown, a sealing ring 8 is fixedly connected to one side of the second flange 4 close to the mounting ring 204. The setting of the sealing ring 8 can make the seal between the first flange 1 and the second flange 4 tighter. The inner walls of the multiple threaded holes 6 on the first flange 1 and the second flange 4 are commonly threadedly connected with bolts 7. The bolts 7 can ensure that the connection between the first flange 1 and the second flange 4 is more reliable. The outer wall of the positioning ring 201 is consistent in diameter with the inner wall of the mounting ring 204.

[0028] The working principle of the utility model is as follows: when the first flange 1 and the second flange 4 need to be connected, the positioning ring 201 on the first flange 1 is aligned with the inside of the mounting ring 204 and the multiple positioning blocks 202 on the positioning ring 201 are aligned with the slide groove 205 on the mounting ring 204, and then the first flange 1 is pushed toward the second flange 4, so that the positioning ring 201 is inserted into the inside of the mounting ring 204 so that one end of the positioning ring 201 contacts the sealing ring 8. At this time, the multiple positioning blocks 202 on the positioning ring 201 also enter the inside of the mounting ring 204 through the slide groove 205, and then the first flange 1 is rotated. As the first flange 1 rotates, the positioning ring 201 and the multiple positioning blocks 202 on the positioning ring 201 can be driven to rotate, and then the multiple positioning blocks 202 will be squeezed. When the multiple positioning blocks 202 are squeezed, they pass through the limiting grooves 301 and the setting of the limit block 302, multiple positioning blocks 202 will move into the corresponding positioning cavity 206 and compress the corresponding spring 207. Then, as the multiple positioning blocks 202 continue to rotate, the multiple positioning blocks 202 are aligned with the positioning groove 203 inside the mounting ring 204. At this time, the multiple springs 207 stretch instantly. As the multiple springs 207 stretch, they can push the corresponding positioning blocks 202 to stretch, so that the multiple positioning blocks 202 cooperate with the corresponding positioning groove 203, so that the relative position of the first flange 1 and the second flange 4 is fixed, and at this time, the multiple threaded holes 6 on the first flange 1 and the second flange 4 are in an aligned state, and then the first flange 1 and the second flange 4 are connected by the cooperation of multiple bolts 7 and the threaded holes 6. The original text highlights the innovative structure and does not elaborate on the existing technology.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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 replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
