[0024] Various specific embodiments of the present application will be described below with reference to the accompanying drawings that form a part of this specification. It should be understood that although terms indicating directions, such as "front", "rear", "up", "down", "left", "right", etc., are used in this application to describe various example structural parts and elements of the present application, these terms are used here only for the purpose of convenience of explanation and are determined based on the example orientations shown in the accompanying drawings. Since the embodiments disclosed in this application can be set in different directions, these directional terms are only for illustration and should not be regarded as limitations. Where possible, the same or similar figure numbers used in this application refer to the same parts.

[0025] Figure 1A is a perspective view of an embodiment of a retaining clip, Figure 1B yes Figure 1A A three-dimensional image from another angle, Figure 1A and Figure 1B The figure shows the appearance of the tube retaining clip. Figure 1A and Figure 1BAs shown, tube retaining clip 100 includes a clamping portion 110 and an inserting portion 120, with clamping portion 110 connected to inserting portion 120. Clamping portion 110 is used to clamp a component, such as a tube. Inserting portion 120 is used to connect to a mounting portion, such as by inserting into a channel of the mounting portion. Retaining clip 100 is used to connect a tube to a mounting portion, such as connecting a tube used to accommodate a zipper cord in a vehicle to a panel of the vehicle.

[0026] The plug-in portion 120 includes a pin portion 171, a flange portion 172 and a pawl 175. The pin portion 171 is connected to the clamping portion 110. The flange portion 172 extends outward from the pin portion 171 and obliquely in a direction away from the clamping portion 110. The flange portion 172 is arranged close to the clamping portion 110. The pawl 175 extends outward from the outer peripheral edge of the pin portion. The pawl 175 includes a plurality of thorn-like structures arranged in sequence. When the plug-in portion 120 enters the channel of the installation portion, the pawl 175 can engage with the inner wall of the channel of the installation portion, thereby connecting the retaining clip to the installation portion. The flange portion 172 is used to limit the depth of the retaining clip 100 inserted into the channel of the installation portion along the insertion direction. In addition, the flange portion 172 has a certain elasticity and can contact the surface of the installation portion, thereby playing a sealing role at the installation channel.

[0027] The clamping portion 110 includes a support seat 103, a first elastic arm 104, and a second elastic arm 105. The support seat 103 includes a base 108, a first support portion 121, and a second support portion 122. The base 108 has a bottom 131, a first side portion 132, and a second side portion 133. The plug-in portion 120 is connected to the bottom 131. In the length direction of the retaining clip 100, the first side portion 132 and the second side portion 133 extend from both ends of the bottom 131 toward a direction away from the plug-in portion 120. In one embodiment of the present application, the height of the first side portion 132 is less than the height of the second side portion 133. The first support portion 121 extends from the first side portion 132 toward a direction away from the plug-in portion 120, and the second support portion 122 extends from the second side portion 133 toward a direction away from the plug-in portion 120.

[0028] The first elastic arm 104 extends obliquely from the distal end 123 of the first support portion 121 toward the base 108, thereby forming an angle between the first elastic arm 104 and the first support portion 121, and a distance between the distal end 143 of the first elastic arm 104 and the first support portion 121. The first elastic arm 104 has a certain degree of elasticity, so that when subjected to force, its distal end 143 can move toward the first support portion 121.

[0029] Similarly, the second elastic arm 105 extends obliquely from the distal end 124 of the second support portion 122 toward the base 108, thereby forming an angle between the second elastic arm 105 and the second support portion 122, and a distance between the distal end 153 of the second elastic arm 105 and the second support portion 122. The second elastic arm 105 has a certain degree of elasticity, so that when subjected to force, its distal end 153 can move toward the second support portion 122.

[0030] The first support portion 121 and the second support portion 122 have similar structures, but differ in height. The first elastic arm 104 and the second elastic arm 105 have similar structures, but differ in height. In the height direction of the retaining clip, the second support portion 122 is taller than the first support portion 121, and the second elastic arm 105 is taller than the first elastic arm 104. Both the distal end 143 of the first elastic arm 104 and the distal end 153 of the second elastic arm 105 are spaced apart from the base 108. The distal end 143 of the first elastic arm 104 is closer to the base 108 than the distal end 153 of the second elastic arm 105.

[0031] The base 108 has a first recess 161 and a second recess 162, with the first recess 161 located below the second recess 162. Along the length of the retaining clamp, the first recess 161 is approximately located in the middle, while the second recess 162 is located between the first recess 161 and the second support portion 122 and arranged toward the first elastic arm 104. The first recess 161 and the distal end 143 of the first elastic arm 104 define a first space 191 capable of accommodating a first component. The second recess 162, the outer side of the first elastic arm 104, and the distal end 153 of the second elastic arm 105 define a second space 192 capable of accommodating a second component. In one embodiment of the present application, the first and second components are both pipes, with the diameter of the first component being larger than that of the second component. The pipe retaining clamp in this embodiment can clamp pipes of different diameters to accommodate different application scenarios.

[0032] Figure 2 yes Figure 1A Side view of the retaining clip. Figure 2As shown, the first recess 161 is recessed from the top of the base 108 toward the bottom 131 of the base 108. The inner wall 244 of the first recess 161 includes an arc segment 221. The arc segment 221 extends circumferentially and extends over half of the circumference of the inner wall 244 of the first recess 161. The arc segment 221 has a first end 222 proximate to the first support portion 121 and a second end 224 proximate to the second support portion 122. The second end 224 is higher than the first end 222 in the height direction H. An opening 225 is formed between the first and second ends 222, 224. The opening 225 is slightly smaller than the diameter of the first component. The distal end 143 of the first elastic arm 104 is arranged toward the opening 225. The end surface of the distal end 143 of the first elastic arm 104 is arc-shaped and substantially aligns with the circumference of the inner wall 244 of the first recess 161. The size of the first component matches the circumference of the inner wall 244 of the first recess 161. When the first component is located in the first space 191, the first component contacts the end face of the distal end 143 of the first elastic arm 104 and the inner wall 244 of the first recess 161, thereby being clamped in the first space 191.

[0033] The second recess 162 extends from the first end 222 of the first recess 161 toward the second elastic arm 105 and is recessed toward the second support portion 122. The inner wall of the second recess 162 is generally arc-shaped. The second elastic arm 105 includes an upper section 251, a middle section 252, and a lower section 253. The outer side of the middle section 252 (i.e., the side away from the first support portion 121) protrudes outward to form a protrusion 258. The outer side of the lower section 253 has a first retaining portion 277, and the outer side of the upper section 251 has a second retaining portion 278. The second recess 162 is arranged toward the first retaining portion 277.

[0034] The distal end 143 of the first resilient arm 104 has a raised resilient arm abutment 288 facing the first support portion 121. The first support portion 121 has a mating portion 289 that is higher than the inner surface of the first support portion 121. The resilient arm abutment 288 can abut against the mating portion 289. The protruding configuration of the resilient arm abutment 288 and the mating portion 289 creates a hollow portion between the first resilient arm 104 and the first support portion 121, thereby providing a certain degree of elasticity for the first retaining portion 277. The first retaining portion 277, the second recess 162, and the distal end 153 of the second resilient arm 105 collectively define a second space 192. The distal end 153 of the second resilient arm 105 is configured in an arc shape to match the shape of the second component.

[0035] In another embodiment of the present application, the elastic arm abutting portion 288 and the matching portion 289 may be protrudingly provided, so that a hollow portion can be formed between the first elastic arm 104 and the first supporting portion 121 .

[0036] Figure 3AA side view of the retaining clip and the first component in FIG1 , Figure 3B yes Figure 1A A side view of the retaining clip holding the first component. Figure 3A and Figure 3B As shown, the first component 301 can be installed into the first space 191 from above the retaining clip. In one embodiment of the present application, the first component 301 is a cylindrical tube. When installing the first component 301, push the first component 301 into the space between the first elastic arm 104 and the second elastic arm 105, apply force to the first component 301, so that the first elastic arm 104 and the second elastic arm 105 are deformed toward the first support portion 121 and the second support portion 122 respectively, and the first component 301 enters the second space 192. Then continue to apply force to the first component 301, squeeze the first elastic arm 104 to continue to deform toward the first support portion 121, and the first component 301 enters the opening 225 of the first recess 161. Continue to apply force to the first component 301, the base 108 has a small amount of elasticity, and the first component 301 can pass through the opening 225 and enter the first space 191. At this time, the first elastic arm 104 recovers its deformation and is located above the first component 301 , and the first component 301 is clamped between the first elastic arm 104 and the first recess 161 .

[0037] join Figure 3B As shown, when the first component 301 is installed in place in the first space 191, the first recess 161 can limit the downward movement of the first component 301 along the length direction L and the height direction H, and the first elastic arm 104 can limit the upward movement of the first component 301 in the height direction H, so that the first component 301 is stably clamped in the first space 191. The arc segment of the first recess 161 exceeds a semicircle, and the opening 225 is smaller than the diameter of the first component 301, so the first component 301 is not easily removed from the first space 191.

[0038] Figure 4A A side view of the retaining clip and the second component in FIG1 , Figure 4B yes Figure 1A A side view of the retaining clip holding the second component. Figure 3A and Figure 3BAs shown, the second component 401 can be installed into the second space 192 from above the retaining clamp. In one embodiment of the present application, the second component 401 is a cylindrical tube. When installing the second component 401, the second component 401 is pushed into the space between the first elastic arm 104 and the second elastic arm 105, and force is applied to the second component 401, so that the first elastic arm 104 and the second elastic arm 105 are deformed toward the first support portion 121 and the second support portion 122 respectively, and the second component 401 enters the second space 192. At this time, the elastic arm abutment portion of the first elastic arm 104 abuts against the first support portion, and the second elastic arm 105 recovers its deformation and is located above the second component 401. The second component 401 is clamped between the first elastic arm 104, the second elastic arm 105 and the second recess 162.

[0039] join Figure 3B As shown, when the second component 401 is installed in the second space 192, the second component 401 compresses the first retaining portion 227 of the first elastic arm 104, causing it to bend and deform toward the first support portion 121, forming a recess that matches the shape of the second component 401. The first retaining portion 227 contacts the second component 401. The second recess 162 has an arc-shaped inner wall that matches the deformation of the second component 401 and contacts the second component 401. The distance between the lower end of the first retaining portion 227 and the lower end of the second recess 162 is less than the diameter of the second component 401, preventing the second component 401 from moving further toward the base 108. The second recess 162 and the first retaining portion 227 simultaneously restrict the movement of the second component 401 in the length direction L. The distal end of the second elastic arm 105 is located above the second component 401, limiting the upward movement of the second component 401 in the height direction. Therefore, the second component 401 is restricted by the first holding portion 227 , the second elastic arm 105 and the second recess 162 and cannot move in any direction, so that the second component 401 is stably clamped in the second space 192 .

[0040] The elastic arm abutment portion 288 of the first elastic arm 104 cooperates with the matching portion 289 of the first support portion 121, so that the first elastic arm 104 and the first support portion 121 form a hollow portion 405, and the hollow portion 405 forms a deformation space, so that the first retaining portion 227 can bend toward the first support portion 121 to better contact the second component 401.

[0041] In the present application, the size of the second component 401 is larger than that of the first component 301 , so that the first component 301 can smoothly pass through the second space 192 .

[0042] Figure 5A is a perspective view of a retaining clip according to a second embodiment of the present application. Figure 5B yes Figure 5AAnother perspective view of the retaining clip. Figure 6 yes Figure 5A Side view of the center retaining clip.

[0043] Figure 5A The embodiment shown is Figure 1A The embodiment shown is similar except that Figure 5A The illustrated embodiment includes a third elastic arm, thereby forming a third space 593 to clamp a third component that is larger than the second treatment element.

[0044] like Figure 5A 、 Figure 5B and Figure 6 As shown, Figure 1A Similar to the embodiment shown, the retaining clip 500 includes a clamping portion 510 and a plug-in portion 520. The plug-in portion 520 is connected to the Figure 1A The clamping portion 510 includes a support base 503, a first elastic arm 504, a second elastic arm 505 and a third elastic arm 506.

The structure of the base 508 is the same as Figure 1A The base 508 of the middle retaining clip 100 has the same structure. The height of the first support portion 521 is higher than Figure 1A The height of the first support portion 121 in the middle retaining clip 100, the first elastic arm 504 is connected to the middle of the first support portion 521, the third elastic arm 506 is connected to the top of the first support portion 521, and the first elastic arm 504 and the third elastic arm 506 are arranged side by side with a spacing.

[0045] The first elastic arm 504 and Figure 1A The first elastic arm 104 has the same structure and has a first retaining portion 527 and a second retaining portion 528. The second elastic arm 505 has a third retaining portion 529. The second elastic arm 505 has an elastic arm abutting portion 628, and the second supporting portion 522 has a matching portion 629, so that the third retaining portion 529 of the second elastic arm 505 has a Figure 1A The first retaining portion 227 has a similar effect.

[0046] and Figure 1ASimilar to the illustrated embodiment, a third space 593 is formed between the second retaining portion 528, the third retaining portion 529, and the distal end 556 of the third elastic arm 506. The third component can be clamped in the third space 593. The second retaining portion 528, the third retaining portion 529, and the distal end 556 of the third elastic arm 506 can all contact the third component, thereby clamping the third component and restricting its movement. The second retaining portion 528, the third retaining portion 529, and the distal end 556 of the third elastic arm 506 contact three parts of the third component. The closest distance between two adjacent parts of the three parts of the third component is less than the diameter of the third component, thereby stably clamping the third component in the third space.

[0047] When the third component is installed in place in the third space 593, the first elastic arm 504 and the second elastic arm 505 are deformed toward their respective support parts and can apply a certain elastic force to the third component, so that the third component is not easy to move.

[0048] In this embodiment, the first space 591, the second space 592, and the third space 593 match the sizes of the first, second, and third components. The size of the third component is set to be larger than the size of the second component, and the size of the second component is larger than the size of the first component, so that components of various sizes can be easily installed.
