[0040] Reference is made below Figures 1-7 The pipe connection structure 1000 according to the embodiment of the utility model is described, after the axial plug-in fit of the first connecting joint 1 and the second connecting joint 3, the radial plug-in of the buckle assembly 5 with the first connecting joint 1 and the second connecting joint 3 is carried out respectively to realize axial fixation, so that the connection strength of the pipe connection structure 1000 can be improved, the reliability and durability of connection are enhanced, and tools are not needed during installation, the operation is simple, at the same time, the number of connecting pieces used is less, and the processing cost is low.

[0041] As Figure 1 The pipe connection structure 1000 according to the embodiment of the utility model, as shown in the drawing, comprises: a first connecting joint 1, a second connecting joint 3 and a buckle assembly 5.

[0042] The first connecting joint 1 is used for being connected with the first pipe 2, the second connecting joint 3 is used for being connected with the second pipe 4, and the second connecting joint 3 is axially plug-in fit with the first connecting joint 1.I.e.the first connecting joint 1 and the first pipe 2 can be connected and fixed, and at the same time, the second connecting joint 3 and the second pipe 4 are connected and fixed, so that when the first connecting joint 1 and the second connecting joint 3 are connected, the first pipe 2 and the second pipe 4 can be relatively fixed.

[0043] It needs to be explained that the pipe connection structure 1000 is used to realize the connection and fixation of two structural members, such as realizing the pipe connection structure 1000 for connecting the flexible shaft and the steel wire rope, wherein the first pipe 2 can be the installation pipe of the flexible shaft, the flexible shaft can be arranged in the first pipe 2, and the second pipe 4 can be the installation pipe of the steel wire rope, the steel wire rope can be arranged in the second pipe 4, so that when the first connecting joint 1 and the second connecting joint 3 are connected, the flexible shaft and the steel wire rope are also relatively fixed, and the first pipe 2 can protect the flexible shaft, the second pipe 4 can protect the steel wire rope, and the connection of the first connecting joint 1 and the second connecting joint 3 can enhance the matching strength of the connection of the flexible shaft and the steel wire rope.

[0044] The buckle assembly 5 is used for radial insertion with the first connecting joint 1 and the second connecting joint 3 respectively to limit the first connecting joint 1 and the second connecting joint 3 in the axial direction. That is, after the first connecting joint 1 and the second connecting joint 3 are axially inserted and matched, the buckle assembly 5 is clamped and limited in the radial direction with the first connecting joint 1 and the second connecting joint 3 respectively, so as to realize the axial limitation of the first connecting joint 1 and the second connecting joint 3. Thus, the first connecting joint 1 and the second connecting joint 3 can be prevented from being separated from each other during use of the catheter connecting structure 1000, thereby improving the connection reliability of the catheter connecting structure 1000 to the two structural members and enhancing the durability of the connection and matching.

[0045] In addition, the first connecting joint 1 and the second connecting joint 3 are clamped and limited by the buckle assembly 5, without the need to set a separate bolt or the like connecting member for fixation, that is, without the need to use a separate wrench or the like dismounting tool to tighten and fix the bolt or the like connecting member, so as to simplify the installation steps, facilitate the operation, and improve the efficiency of installation and dismounting. At the same time, the clamping and limitation is realized by setting the buckle assembly 5, without the need to set a plurality of bolts in the circumferential direction of the first connecting joint 1 and the second connecting joint 3 as in the traditional design, such as 6 or 8 in some prior art, thereby greatly reducing the number of connecting members and lowering the setting cost.

[0046] According to the catheter connecting structure 1000 of the utility model, after the axial insertion and matching of the first connecting joint 1 and the second connecting joint 3, the radial clamping of the buckle assembly 5 is used to realize the axial limitation, which is beneficial to improve the connection reliability of the catheter connecting structure 1000, and the installation mode is simple, without the need to use a wrench or the like tool for installation, the operation is simple, the number of connecting members used is small, and the processing cost is low.

[0047] In some embodiments, the buckle assembly 5 includes a first buckle 51 and a second buckle 52, the first buckle 51 and the second buckle 52 are axially inserted and matched in the radial direction of the first connecting joint 1, and the first buckle 51 is configured to be axially limited and matched with the first connecting joint 1 and the second connecting joint 3 respectively. Thus, the first buckle 51 and the second buckle 52 can be inserted into the matching positions of the first connecting joint 1 and the second connecting joint 3 from opposite directions respectively to axially limit the first connecting joint 1 and the second connecting joint 3.

[0048] The first buckle 51 can be configured as an inner buckle, and the second buckle 52 can be configured as an outer buckle, and the first buckle 51 and the second buckle 52 are axially inserted and matched in the radial direction. Figure 5 And Figure 6 As shown in Figs. 1 and 2, the first buckle 51 and the second buckle 52 are arranged opposite to each other in the radial direction of the first connecting joint 1. Figure 6As shown, the first buckle 51 and the second buckle 52 can be configured as a U-shaped structure, that is, each of them is formed with an avoiding space for avoiding the first connecting joint 1 and the second connecting joint 3, which not only facilitates the clamping cooperation of the buckle assembly 5 but also can avoid the first connecting joint 1 and the second connecting joint 3. That is, the clamping cooperation of the first buckle 51 and the second buckle 52 can make them play the role of mutual structural reinforcement, avoid the structure fracture of the single first buckle 51 during clamping limiting, and ensure the structural strength of the buckle assembly 5.

[0049] In addition, it should be noted that the materials of the first buckle 51 and the second buckle 52 can be metal materials to ensure the structural strength of the buckle assembly 5 and ensure the limiting strength and stability. Or it can also be configured as a non-metal material to facilitate the reduction of the setting cost. That is, the material of the buckle assembly 5 is not limited to a certain specific material, such as plastic, stainless steel, various alloys, etc. during actual setting.

[0050] In some embodiments, the first connecting joint 1 is provided with a first limiting clamping groove 11, and the first buckle 51 includes a first clamping part 511 for radial insertion with the first limiting clamping groove 11, that is, when the first buckle 51 is inserted and cooperated with the first connecting joint 1, the first clamping part 511 can be radially inserted into the first limiting clamping groove 11, so that the first clamping part 511 and the inner wall of the first limiting clamping groove 11 can be limited and stopped in the axial direction of the first connecting joint 1.

[0051] And / or, in other embodiments, the second connecting joint 3 is provided with a second limiting clamping groove 31, and the first buckle 51 includes a second clamping part 512 for radial insertion with the second limiting clamping groove 31. That is, when the first buckle 51 is inserted and cooperated with the second connecting joint 3, the second clamping part 512 can be radially inserted into the second limiting clamping groove 31, so that the second clamping part 512 and the inner wall of the second limiting clamping groove 31 can be limited and stopped in the axial direction of the second connecting joint 3.

[0052] Therefore, after the first connecting joint 1 and the second connecting joint 3 are axially connected, the first buckle 51 can be radially and axially limited with the first connecting joint 1 through the first clamping part 511 and axially limited with the second connecting joint 3 through the second clamping part 512, so that the limiting and fixing of the two connecting joints can be realized through one first buckle 51, which facilitates to improve the limiting efficiency.

[0053] Specifically, as Figure 2 and Figure 3As shown, the first limiting clamping groove 11 can be configured as an annular clamping groove provided on the outer peripheral wall of the first connecting joint 1, and the second limiting clamping groove 31 can be configured as an annular clamping groove provided on the outer peripheral wall of the second connecting joint 3, that is, the first limiting clamping groove 11 and the second limiting clamping groove 31 can be configured as annular clamping grooves, so that after the first connecting joint 1 and the second connecting joint 3 are axially inserted, when the first connecting joint 1 and the second connecting joint 3 are relatively rotated to any angle, the first clamping portion 511 and the second clamping portion 512 can be radially inserted into the first limiting clamping groove 11 and the second limiting clamping groove 31 from the same direction on the same side. Therefore, it is beneficial to improve the flexibility of the insertion limiting, without separately spending time to accurately insert the first clamping portion 511 and the first limiting clamping groove 11, the second clamping portion 512 and the second limiting clamping groove 31, thereby improving the assembly efficiency.

[0054] In some embodiments, the first clasp 51 further comprises an intermediate connecting portion 513 connected between the first clamping portion 511 and the second clamping portion 512, and the first clamping portion 511 and the second clamping portion 512 are oppositely distributed. That is, as shown in the first embodiment of the present application, Figure 1 As shown, the first clamping portion 511 and the second clamping portion 512 are connected to each other through the intermediate connecting portion 513, and the first clamping portion 511 and the second clamping portion 512 are oppositely distributed in the axial direction of the first connecting joint 1 and the second connecting joint 3. In this way, after the first clamping portion 511 and the first limiting clamping groove 11 are clamped and matched, and the second clamping portion 512 and the second limiting clamping groove 31 are clamped and matched, the intermediate connecting portion 513 can play a connecting and restraining role between the two clamping portions, and then by using the connecting role of the intermediate connecting portion 513, the axial limiting of the first connecting joint 1 and the second connecting joint 3 is realized.

[0055] Among them, the first clamping portion 511 can be fixedly connected with the intermediate connecting portion 513, such as being connected by welding or other ways, and at the same time, the second clamping portion 512 can be fixedly connected with the intermediate connecting portion 513, such as being connected by welding or other ways, such as in some specific embodiments, the first clamping portion 511, the intermediate connecting portion 513 and the second clamping portion 512 can be designed in an integral molding manner to enhance the structural strength of each part of the structure, thereby enhancing the reliability of the clamping limiting.

[0056] In some embodiments, the second buckle 52 is provided with a first insertion slot 521 and a second insertion slot 522, the first clamping portion 511 is further used for insertion fitting with the first insertion slot 521, and the second clamping portion 512 is further used for insertion fitting with the second insertion slot 522. In other words, the first insertion slot 521 and the second insertion slot 522 are spaced apart on the second buckle 52, and the first insertion slot 521 and the second insertion slot 522 are open in the same direction of the second buckle 52, while the first clamping portion 511 and the second clamping portion 512 protrude and extend in the same direction of the first buckle 51.

[0057] Thus, as shown in Figure 1 、 Figure 5 and Figure 6 , when the first buckle 51 and the second buckle 52 are clamped and fitted, the first clamping portion 511 and the first insertion slot 521 are inserted in the radial direction of the first connecting joint 1, while the second clamping portion 512 and the second insertion slot 522 are inserted in the radial direction of the second connecting joint 3, so that the clamping and fitting of the first buckle 51 and the second buckle 52 can be achieved, the structure is simple, and the clamping mode is beneficial to quick connection.

[0058] In this way, after the first buckle 51 and the second buckle 52 are clamped and fitted, the first clamping portion 511 and the inner wall of the first insertion slot 521 can play a role of mutual strengthening and supporting, and the second clamping portion 512 and the inner wall of the second insertion slot 522 can also play a role of mutual strengthening and supporting, that is, the first buckle 51 and the second buckle 52 can achieve insertion and embedded type of strengthening fitting, which is beneficial to improve the overall structural strength of the buckle assembly 5, so that when there is a large separation action at the connection of the first connecting joint 1 and the second connecting joint 3, the buckle assembly 5 can also maintain sufficient limiting force to ensure the limiting strength.

[0059] In some embodiments, the first clamping portion 511 is formed with a first avoiding gap 5111, and the second buckle 52 is further provided with a first penetrating gap 5211 opposite to the first avoiding gap 5111, and the first avoiding gap 5111 and the first penetrating gap 5211 are both used for penetrating to avoid the first connecting joint 1. As shown in Figure 1 、 Figure 6 , the first clamping portion 511 includes two spaced apart first clamping plates 5112, and the first avoiding gap 5111 is formed between the two first clamping plates 5112, that is, when the first clamping portion 511 is clamped and fitted with the first connecting joint 1, the two first clamping plates 5112 are clamped on the radial sides of the first connecting joint 1, respectively, and the first connecting joint 1 penetrates the first avoiding gap 5111.

[0060] The inner side edge of the first avoiding gap 5111 can be configured as an arc-shaped edge, that is, the edge of the first clamping plate 5112 towards the first avoiding gap 5111 is configured as an arc-shaped edge, so that the first clamping plate 5112 can be closely fitted with the outer side surface of the first connecting joint 1, and the compactness of the limiting clamping is ensured. Meanwhile, the first penetrating gap 5211 of the second clamping buckle 52 can also avoid the first connecting joint 1, which is beneficial to the closer insertion of the first clamping part 511 and the first insertion slot 521.

[0061] And / or, the second clamping part 512 is formed with a second avoiding gap 5121, and the second clamping buckle 52 is also provided with a second penetrating gap 5221 opposite to the second avoiding gap 5121, and the second avoiding gap 5121 and the second penetrating gap 5221 are both used for penetrating the second connecting joint 3. As shown in Figure 1 、 Figure 6 The second clamping part 512 includes two spaced-apart second clamping plates 5122, and the second avoiding gap 5121 is formed between the two second clamping plates 5122, that is, when the second clamping part 512 is clamped and matched with the second connecting joint 3, the two second clamping plates 5122 are clamped on the radial two sides of the second connecting joint 3 respectively, and meanwhile, the second connecting joint 3 penetrates the second avoiding gap 5121.

[0062] The inner side edge of the second avoiding gap 5121 can be configured as an arc-shaped edge, that is, the edge of the second clamping plate 5122 towards the second avoiding gap 5121 is configured as an arc-shaped edge, so that the second clamping plate 5122 can be closely fitted with the outer side surface of the second connecting joint 3, and the compactness of the limiting clamping is ensured. Meanwhile, the second penetrating gap 5221 of the second clamping buckle 52 can also avoid the second connecting joint 3, which is beneficial to the closer insertion of the first clamping part 511 and the second insertion slot 522.

[0063] Therefore, by arranging the first avoiding gap 5111, the first penetrating gap 5211, the second avoiding gap 5121 and the second penetrating gap 5221, the first clamping buckle 51, the first clamping buckle 51 and the second clamping buckle 52 can be compactly installed, which is beneficial to enhancing the reliability and durability of the clamping limiting of the clamping buckle assembly 5.

[0064] It should be noted that the shapes of the first avoiding gap 5111, the first penetrating gap 5211, the second avoiding gap 5121 and the second penetrating gap 5221 are not limited to the above-mentioned circular shape, but can also be square or other shapes.

[0065] In some embodiments, one of the first buckle 51 and the second buckle 52 is provided with a clamping protrusion 53, which is suitable for clamping the other one of the first buckle 51 and the second buckle 52. That is, the clamping protrusion 53 can be arranged on the first buckle 51 to be clamped with the second buckle 52, or the clamping protrusion 53 can be arranged on the second buckle 52 to be clamped with the first buckle 51, and the arrangement is flexible and optional, and the clamping of both can be achieved.

[0066] In the specific design, as shown in Figure 6 , the second buckle 52 is provided with two clamping protrusions 53, and the two clamping protrusions 53 are arranged at the bottom of the second buckle 52 and are spaced apart and distributed at both ends of the bottom of the second buckle 52. And as shown in Figure 5 , after the first buckle 51 and the second buckle 52 are clamped and matched, the first buckle 51 extends upward into the second buckle 52, and the two clamping protrusions 53 extend to the bottom of the first buckle 51 to be clamped with the bottom surface of the first buckle 51, that is, the clamping protrusion 53 is clamped in the middle connecting portion 513, so that the first buckle 51 can be stably clamped and limited in the second buckle 52 by the two clamping protrusions 53, so that the structure of the buckle assembly 5 is more stable.

[0067] In some embodiments, at least part of the first connecting joint 1 is inserted into the second connecting joint 3; wherein one of the outer peripheral wall of the first connecting joint 1 and the inner peripheral wall of the second connecting joint 3 is provided with a limiting column 12 and the other is provided with a limiting groove 32, and the limiting column 12 is used for limiting cooperation with the limiting groove 32 along the axial direction of the first connecting joint 1. That is, the limiting column 12 can be arranged on the outer peripheral wall of the first connecting joint 1, and the limiting groove 32 can be arranged on the inner peripheral wall of the second connecting joint 3, or the limiting groove 32 can be arranged on the outer peripheral wall of the first connecting joint 1, and the limiting column 12 can be arranged on the inner peripheral wall of the second connecting joint 3, and the axial limiting and fixing of the first connecting joint 1 and the second connecting joint 3 can be realized through the cooperation of the limiting column 12 and the limiting groove 32.

[0068] Specifically, as shown in Figure 3 , the outer peripheral wall of the first connecting joint 1 is provided with a limiting column 12, and the inner wall of one end of the second connecting joint 3 is provided with a limiting groove 32, wherein the limiting groove 32 is configured as an axial portion and a circumferential portion connected, the axial portion extends along the axial direction of the second connecting joint 3 and is open at the end surface of the second connecting joint 3, and the circumferential portion extends along the circumferential direction of the inner wall of the second connecting joint 3.

[0069] Thus, when the first connecting joint 1 is axially inserted into the second connecting joint 3, the limiting post 12 enters into the axial portion from the end of the second connecting joint 3, and after being inserted to a certain depth, the first connecting joint 1 and the second connecting joint 3 can be driven to rotate, so that the limiting post 12 enters into the circumferential portion, at this time, the limiting post 12 and the limiting groove 32 can be axially limited and matched with the first connecting joint 1, thereby achieving the limiting locking of the first connecting joint 1 and the second connecting joint 3, and improving the connection reliability.

[0070] In some embodiments, the first conduit 2 is axially inserted and matched with the first connecting joint 1, one of the first conduit 2 and the first connecting joint 1 is provided with the first anti-disengagement barb structure 13, and the first anti-disengagement barb structure 13 is used for the axial limiting and matching of the other one of the first conduit 2 and the first connecting joint 1.
