[0036] Embodiment one

[0037] Referring to Figure 2 , which shows one example of the pig nose seat pipe clamp provided by the utility model.

[0038] As shown in the figure, the pig nose seat pipe clamp of the present example mainly comprises a decoration assembly 1, a fixed seat 2 and a clamping assembly 3.

[0039] In combination with Figures 2 to 5 , the first end portion 21 of the fixed seat 2 is fixedly connected with the decoration assembly 1, the second end portion 22 of the fixed seat 2 is rotationally connected with the clamping assembly 3, one end of the clamping assembly 3 is formed with a clamping ring 31 for cooperating with the frame of the bicycle, the other end is formed with an operating handle 32, the operating handle 32 is connected with the fixed seat 2 through an elastic connecting piece 4, the operating handle 32 is configured to drive the clamping ring 31 to relatively rotate around the second end portion 22 of the fixed seat 2 to control the opening and closing state of the clamping ring 31, the elastic connecting piece 4 is configured to provide clamping force to the operating handle 32 in the clamping state, so that the clamping ring 31 can be opened under the driving of the operating handle 32 to clamp the frame of the bicycle, after the operating handle is loosened, the clamping force of the elastic connecting piece 4 acts on the clamping ring 31 in the clamping state of the clamping ring 31, the clamping ring 31 is tightly clamped on the frame of the bicycle, so that the pig nose seat pipe clamp is directly and quickly installed on the bicycle frame, without the need to reserve any installation component on the bicycle, thereby being applicable to all bicycles and being able to adjust the installation position and the installation quantity, improving the adaptability and functionality of the pig nose seat pipe clamp.

[0040] Among them, in combination with Figures 6 to 8 , the first end portion 21 of the fixed seat 2 is formed with an axial fixing slot hole 23 for cooperating with the decoration assembly 1 in the region, and the second end portion 22 is formed with a radial pivot slot hole 24 for cooperating with the clamping assembly 3, so that the decoration assembly 1 and the clamping assembly 3 can be stably connected with the fixed seat 2 through the axial fixing slot hole 23 and the radial pivot slot hole 24 respectively.

[0041] As a preferred arrangement, the two axial fixing slot holes 23 are uniformly distributed in the first end portion 21 of the fixed seat 2 and axially extend towards the second end portion 22, forming two uniformly distributed axial long slots in the region of the first end portion 21, and further, the axial fixing slot hole 23 is further formed with a fixing nut 231, facilitating the fixation of the screw.

[0042] In combination Figure 4 And Figure 5 In combination, the end face of the decoration assembly 1 matched with the fixed seat 2 is formed with a fixed hole 11 matched with the axial fixed slot hole 23, so that after the first end 21 of the decoration assembly 1 and the fixed seat 2 abut, the screw is inserted into the axial fixed slot hole 23 through the fixed hole 11, and is fixed by the fixed nut 231 arranged in the axial fixed slot hole 23, so that the decoration assembly 1 and the fixed seat 2 can be fixedly connected.

[0043] In combination Figures 6 to 8 Further, the radial rotation shaft slot hole 23 is distributed in the second end 22 of the fixed seat 2 and is distributed in the axial direction, so that the middle region of the clamping assembly 1 is arranged in the second end 22 of the fixed seat 2, and the clamping assembly 1 and the fixed seat 2 are rotationally connected by the rotation shaft passing through the radial rotation shaft slot hole 24, so that the clamping assembly 1 can rotate relative to the fixed seat 2 and directly clamp the frame of the bicycle without reserving installation components on the frame of the bicycle.

[0044] Therefore, the axial fixed slot hole 23 and the radial rotation shaft slot hole 24 of the fixed seat 1 are respectively connected with the decoration assembly 1 and the clamping assembly 2 by the axially distributed screw and the radially distributed rotation shaft, and the screw and the rotation shaft can respectively serve as the axial reinforcing rib and the radial reinforcing rib in the fixed seat 1 to axially and radially reinforce the fixed seat 1, improve the stability and reliability of the fixed seat 1, and thus prevent the swaying of the fixed seat pipe clamp.

[0045] In combination Figure 4 And Figure 5 In combination, the clamping assembly 3 includes the first clamping arm 33 and the second clamping arm 34 which are symmetrically distributed, the middle regions of the first clamping arm 33 and the second clamping arm 34 are respectively formed with the first ear plate 331 and the second ear plate 341 matched with the second end 22 of the fixed seat 2, and the first ear plate 331 and the second ear plate 341 are respectively formed with the rotation shaft hole 35 matched with the radial rotation shaft slot hole 24, so that after the first ear plate 331 and the second ear plate 341 of the first clamping arm 33 and the second clamping arm 34 abut with the second end 22 of the fixed seat 2, the rotation shaft hole 35 coincides with the radial rotation shaft slot hole 24, the rotation shaft can pass through the rotation shaft hole 35 and be inserted into the radial rotation shaft slot hole 24, so as to rotationally connect the first clamping arm 33 and the second clamping arm 34 with the fixed seat 2 respectively, so that the first clamping arm 33 and the second clamping arm 34 can relatively rotate around the fixed seat 2.

[0046] Further, the first ear plate 331 of the first clamping arm 33 is formed with a groove 332 matched with the second ear plate 341, so that the second ear plate 341 of the second clamping arm 34 can be embedded in the groove 332 of the first ear plate 331, ensuring that the connection area of the first ear plate 331 and the second ear plate 341 is flat, and at the same time, the relative rotation angle of the first clamping arm 33 and the second clamping arm 34 is limited and guided by the groove 332, ensuring the stability of the cooperation of the first clamping arm 33 and the second clamping arm 34.

[0047] In order to enable the clamping assembly 3 to stably clamp the frame of the bicycle, one end of the first clamping arm 33 and the second clamping arm 34 is respectively formed with a first clamping opening 333 and a second clamping opening 342 extending in a circular arc shape towards the fixed seat 2, and the other end is respectively formed with a first clamping handle 334 and a second clamping handle 343 extending away from the fixed seat 2, so that the first clamping opening 333 and the second clamping opening 342 cooperatively form a circular clamping ring 31, and at the same time, the first clamping handle 334 and the second clamping handle 343 cooperatively form an operation handle 32.

[0048] Therefore, in combination with Figure 2 and Figure 3 , pressing or loosening the operation handle 32 can drive the first clamping arm 33 and the second clamping arm 34 to rotate relatively, so that the first clamping opening 333 and the second clamping opening 342 move away from each other or move close to each other, thereby controlling the opening and closing state of the clamping ring 31, facilitating the fixing and adjustment of the installation position of the pig nose seat pipe clamp, and also being able to be arranged at multiple positions of the bicycle frame, increasing the installation quantity of the pig nose seat pipe clamp.

[0049] As an example, when the operation handle 32 is pressed, the first clamping handle 334 and the second clamping handle 343 move close to each other to drive the first clamping opening 333 and the second clamping opening 342 to rotate away from each other, thereby opening the clamping ring 31, so that the clamping ring 31 can clamp the frame of the bicycle.

[0050] At the same time, by adjusting the relative rotation angle of the first clamping opening 333 and the second clamping opening 342, the opening size of the clamping ring 31 can be adjusted, so that the clamping assembly 3 can be applied to bicycle frames with different pipe diameters, such as handlebars and head tubes of bicycles, thereby being applicable to all bicycle frames without the need to reserve installation components.

[0051] Correspondingly, when the operation handle 32 is loosened, the first clamping handle 334 and the second clamping handle 343 move away from each other to drive the first clamping opening 333 and the second clamping opening 342 to rotate close to each other, thereby closing the clamping ring 31, so that the clamping ring 31 is clamped on the frame of the bicycle.

[0052] In order to ensure that the clamping ring 31 can be firmly clamped on the frame of the bicycle and is not easy to shake and fall off, the first clamping handle 334 and the second clamping handle 343 are respectively connected with the first end portion 21 area of the fixed seat 2 through the elastic connecting piece 4, and the elastic connecting piece 4 is configured to provide clamping force to the first clamping handle 334 and the second clamping handle 343 in the clamping state, so as to improve the connection stability of the clamping ring 31 and the bicycle frame.

[0053] In combination Figure 4 and Figure 5 , as a preferred setting scheme, the elastic connecting piece 4 is composed of a spring 41, and the first end portion 21 area of the fixed seat 2 is respectively provided with two groups of first connecting grooves 25 for cooperating with the spring 41, as shown in Figure 8 , the inner sides of the first clamping handle 334 and the second clamping handle 343 are also respectively provided with two groups of second connecting grooves 36 for cooperating with the spring 41, so that one end of the two groups of springs 41 is embedded in the first connecting grooves 25 of the first end portion 21 area of the fixed seat 2, and the other end is embedded in the second connecting grooves 36 of the inner sides of the first clamping handle 334 and the second clamping handle 343, and the spring 41 respectively applies a pushing force to the first clamping handle 334 and the second clamping handle 343 in the initial state, so that the pushing force is transmitted to the first clamping port 333 and the second clamping port 342 as a clamping force for pressing the clamping ring 31, so that when the clamping ring 31 closes and clamps the bicycle frame, the spring 41 can provide a clamping force for the clamping ring 31, ensuring the stable clamping of the clamping ring 31 and the bicycle frame, so that the pig nose seat pipe clamp can be directly installed on the bicycle frame without cooperation with the reserved parts, and is not easy to shake and fall off.

[0054] At the same time, in the process of repeatedly pressing the operation handle 32, the spring 41 repeatedly changes between compression and elongation, and the two ends of the spring 41 are always embedded in the first connecting grooves 25 and the second connecting grooves 36, ensuring that the spring 41 will not deviate when elongated, so that the clamping force acting on the operation handle 32 and the clamping ring 31 is stably transmitted, and displacement of the operation handle 32 and the clamping ring 31 is avoided, further improving the stability and reliability of the pig nose seat pipe clamp, and preventing it from shaking and falling off.

[0055] Further, the first clamping handle 334 and the second clamping handle 343 are configured to extend away from the fixed seat 2, so that the operation handle 32 has a larger operation space and is not easy to collide during repeated pressing.

[0056] In combination Figure 6In cooperation with the above, the two sides of the fixed seat 2 are formed with concave operation curved surfaces 26, so that the concave operation curved surfaces 26 cooperate with the first clamping handle 334 and the second clamping handle 343 extending away from the fixed seat 2 to provide more operation space for the operation handle 32, ensure that the operation handle 32 does not collide, and further increase the opening size of the clamping ring 31, so that the clamping ring 31 can be applied to bicycle frames of different pipe diameters, and the adaptability of the pig nose seat pipe clamp is improved.

[0057] In combination Figure 5 and Figure 9 Further, the ends of the first clamping opening 333 and the second clamping opening 342 are respectively formed with first extension plates 335 and second extension plates 344, and the first extension plates 335 and the second extension plates 344 are respectively distributed in opposite areas of the ends of the first clamping opening 333 and the second clamping opening 342, so that the first extension plates 335 and the second extension plates 344 are staggered to be distributed in the upper and lower areas of the bicycle frame when the clamping ring 31 clamps the bicycle frame, so as to improve the stability of the clamping ring 31.

[0058] At the same time, when the clamping ring 31 clamps the bicycle frame with a larger pipe diameter, so that the clamping ring 31 cannot be completely closed, the first extension plate 335 abuts against the upper area of the bicycle frame, and the second extension plate 344 abuts against the lower area of the bicycle frame, which can improve the clamping reliability of the clamping ring 31 on the bicycle frame with a larger pipe diameter.

[0059] In combination Figures 4 to 6 In order to further improve the clamping stability of the clamping ring 31, the end face of the fixed seat 2 is formed with an abutting curved surface 27 for cooperating with the bicycle frame, so that when the clamping ring 31 clamps the bicycle frame, the abutting curved surface 27 of the fixed seat 2, the inner sides of the first clamping opening 333 and the second clamping opening 342 respectively tightly abut against the bicycle frame, and the clamping reliability is ensured.

[0060] Further, the abutting curved surface 27 of the fixed seat 2, the inner sides of the first clamping opening 333 and the second clamping opening 342 are respectively provided with a friction layer 37, so that the friction layer 37 can increase the friction force between the abutting curved surface 27 of the fixed seat 2, the first clamping opening 333 and the second clamping opening 342 and the bicycle frame, thereby improving the clamping stability and reliability, so that the pig nose seat pipe clamp is not easy to shake and fall off.

[0061] As an example, the friction layer 37 can be composed of an existing rubber layer or a cork layer, or composed of a plurality of uniformly distributed friction ridges to improve the abutting friction force between the friction layer 37 and the bicycle frame.

[0063] In combination Figure 10 andFigure 11 In order to improve the reliability of the pig nose seat clamp, on the basis of the first embodiment, the first clamping handle 334 and the second clamping handle 343 of the clamping assembly 3 are connected by three groups of springs 41, so as to increase the clamping force provided by the three groups of springs 41 to the clamping ring 31, and ensure the stability of the connection between the clamping ring 31 and the bicycle frame.

[0064] Specifically, the first end portion 21 region of the fixed seat 2 is respectively provided with three groups of first connecting grooves 25 for cooperating with the springs 41, and the inner sides of the first clamping handle 334 and the second clamping handle 343 are also respectively provided with three groups of second connecting grooves 36 for cooperating with the springs 41, so that the three groups of springs 41 are distributed in a triangular shape, one end of each spring 41 is embedded in the first connecting groove 25 of the first end portion 21 region of the fixed seat 2, and the other end is embedded in the second connecting groove 36 of the inner side of the first clamping handle 334 and the second clamping handle 343, so as to ensure the stability of the connection between the three groups of springs 41 and the fixed seat 2 and the clamping assembly 3, and provide a larger clamping force for the clamping ring 31, so as to ensure the stable clamping of the clamping ring 31 to the bicycle frame, thereby preventing the pig nose seat clamp from shaking and falling off.

[0065] Further, the second end portion 22 of the fixed seat 2 is respectively provided with limiting blocks 28 for cooperating with the clamping assembly 3, so that the limiting blocks 28 can limit the first clamping arm 33 and the second clamping arm 34 respectively, thereby preventing the first clamping arm 33 and the second clamping arm 34 from shaking.

[0066] In combination with Figure 12 and Figure 13 , specifically, the first limiting block 281 is arranged on the side where the second end portion 22 cooperates with the first ear plate 331 of the first clamping arm 33, and is distributed near the end of the first clamping arm 33, limiting the shaking of the first ear plate 331, and correspondingly, the second limiting block 282 is arranged on the side where the second end portion 22 cooperates with the second ear plate 341 of the second clamping arm 34, and is distributed near the end of the second clamping arm 34, limiting the shaking of the second ear plate 341.

[0067] The limiting blocks 28 thus formed, the first limiting block 281 and the second limiting block 282 are staggered, which will not hinder the connection between the first ear plate 331 and the second ear plate 341 and the fixed seat 2, and can also cooperate with each other to limit the shaking of the first clamping arm 33 and the second clamping arm 34, thereby improving the stability of the pig nose seat clamp.
