[0047] The embodiment of the present application provides a hollow cable tie fastener, which solves the problem in the prior art that the operator has high labor intensity when installing the fastener, cannot accurately observe the installation process and the internal connection status after installation, and cannot effectively check the installation effect.

[0048] The technical solution in the embodiments of the present application is to solve the above-mentioned problems by configuring the main structure of the fixer so that the structure of the stud can be observed from the side, and by configuring a snap joint inside the main structure that is easy to elastically deform and flip, and by the snap joint acting differently from the stud during the insertion and removal processes, the effects of low insertion force and high extraction force are achieved, thereby effectively solving the problems of high labor intensity and inability to effectively inspect the installation effect, and improving work efficiency.

[0049] In order to better understand the technical solution of the present application, the technical solution is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0050] Example 1:

[0051] like Figure 1-Figure 7 As shown, the hollow cable tie fastener of this embodiment includes a positioning ring 1, a pair of first support bodies 4, a second support body 3, a pair of clamping joints 2 and a fixing portion 5.

[0052] A positioning ring 1, the middle of which is a through hole for passing the stud 9;

[0053] a pair of first support bodies 4, one end of each of the first support bodies 4 being connected to the positioning ring 1, and the two first support bodies 4 being symmetrical about the axis of the positioning ring 1;

[0054] The second support body 3 is located between the two first support bodies 4 and one end of the second support body 3 is connected to the positioning ring 1. The second support body 3 and the first support body 4 are spaced apart.

[0055] A pair of clamping joints 2 are elastically connected to the inner side of a first support body 4 respectively, and each clamping joint 2 is provided with a plurality of teeth 22 that cooperate with the threads of the stud 9;

[0056] A fixing portion 5, used for fixing and connecting the first support 4 and the other end of the second support 3;

[0057] Among them, when the stud 9 is inserted, the two card joints 2 and the stud 9 are flipped away from each other; when the teeth 22 are embedded in the bottom of the thread from both sides of the stud 9, the fixer is connected to the stud 9; when the stud 9 is pulled out, the two card joints 2 are flipped towards each other, and the multiple teeth 22 cooperate with the thread of the stud 9 to limit the fixer.

[0058] Specifically, the holder is integrally formed, and the forming process can be left and right mold forming; the first support body 4 and the second support body 3 are spaced apart from each other, such as Figure 1 As shown, the lower ends of the first support body 4 and the second support body 3 are connected to the upper surface of the positioning ring 1, and the upper ends of the first support body 4 and the second support body 3 are connected to the fixing portion 5. After being connected with the positioning ring 1, a space and channel for accommodating the stud 9 are formed. The action process and connection status of the card joint 2 and the stud 9 can be observed from the hollow part between the first support body 4 and the second support body 3;

[0059] The card connector 2 is elastically connected to the first support 4, which facilitates the swinging of the card connector 2 relative to the first support 4, so that the insertion force when inserting the stud 9 is small;

[0060] After the stud 9 is inserted, the bottom pair of teeth 22 are embedded in the bottom of the thread from both sides of the stud 9. Generally, when installing the fixture, the fixture is inserted to the bottom until it can no longer move relative to the stud 9.

[0061] When the stud 9 is pulled out, the bottom pair of teeth 22 is engaged with the stud 9, so that the two clamping joints 2 are flipped toward each other when the fixer moves relative to the stud 9. The multiple teeth 22 squeeze the stud 9 from both sides of the stud 9 and partially embed into the bottom of the thread teeth, preventing the stud 9 from moving. Therefore, the required pulling-out force is relatively large.

[0062] The hollow cable tie fastener of this embodiment forms the external structural main body of the fastener by arranging a plurality of support bodies at intervals. A pair of clamping joints 2 that facilitate bidirectional elastic flipping are elastically connected to the support bodies. The teeth 22 on the clamping joints 2 are used to achieve clamping and limiting with the studs 9, thereby reducing the insertion force of the cable tie fastener while ensuring the connection effect, and allowing the internal connection status of the fastener after installation to be observed, thereby reducing labor intensity and ensuring the installation effect.

[0063] Example 2:

[0064] Based on the first embodiment, the main structure of the fixer is optimized to further ensure the installation effect.

[0065] like Figure 4 As shown, the number of the second supporting bodies 3 in this embodiment is two, which are arranged opposite to each other and are respectively located on both sides of the stud 9.

[0066] like Figure 5 -like Figure 7 As shown, a guide structure 8 is provided inside the first support body 4 between the clamping joint 2 and the fixing portion 5 . The two guide structures 8 are used to limit the stud 9 from both sides of the stud 9 .

[0067] like Figure 7As shown, when the stud 9 passes through the through hole and contacts the guide structure 8, the guide structure 8 can ensure that the stud 9 is located at the center of the fixture, preventing the stud 9 from deviating and falling, thereby ensuring the installation effect.

[0068] In addition, if Figure 1 ,like Figure 4 As shown, in the cross-sectional direction of the stud 9, the width of the clamping joint 2 is adapted to the width of the guide structure 8, and is used to match and limit the stud 9 so that the stud 9 is located at the center of the fixture.

[0069] The number of the second support body 3 and the first support body 4 are two and they are arranged in a cross shape. Figure 4 As shown, the second support bodies 3 located on both sides of the stud 9 also play a guiding and limiting role.

[0070] like Figure 6 As shown, the guide structure 8 includes a first elastic connecting portion 81 and an extension portion 82. The extension portion 82 is elastically connected to the first support body 4 through the first elastic connecting portion 81. A guide portion 83 is provided at the end of the extension portion 82. The guide portion 83 contacts and cooperates with the stud 9 and faces the insertion direction of the stud 9.

[0071] Specifically, such as Figure 6 As shown, the first elastic connection part 81 is U-shaped as a whole, connecting the extension part 82 and the first support body 4, so that the guide part 83 is oriented towards the insertion direction of the stud 9. At the same time, the elastic ability of the first elastic connection part 81 makes the guide part 83 have a certain elasticity when in contact with the stud 9. The guide part 83 clamps the stud 9 from both sides of the stud 9, playing a guiding and limiting role.

[0072] like Figure 1 As shown, the extension portion 82 is in a sheet shape, the guide portion 83 is a straight edge, and the thickness of the guide portion 83 is greater than the thickness of the extension portion 82 .

[0073] The thickness of the guide portion 83 is greater than the thickness of the extending portion 82 , thereby ensuring the strength of the guide portion 83 .

[0074] Example 3:

[0075] In order to further ensure the limiting effect during the cooperation between the clamping joint 2 and the stud 9, based on the above embodiment, the relevant structure of the clamping joint 2 is further optimized. The specific solution is as follows:

[0076] like Figure 6 As shown, it further includes a second elastic connection portion 21 , through which the card joint 2 is elastically connected to the first support body 4 , and a cross section of the second elastic connection portion 21 is smaller than a cross section of the card joint 2 .

[0077] Specifically, the cross section refers to a cross section that is consistent with the cross section direction of the stud 9 ; the cross-sectional size of the second elastic connecting portion 21 ensures connection strength and good deformation ability, and facilitates flipping of the card joint 2 .

[0078] like Figure 6 As shown, a limiting portion 23 is provided on the clamping joint 2 . The limiting portion 23 is located between the plurality of teeth 22 and the positioning ring 1 . There is a gap between the limiting portion 23 and the second elastic connecting portion 21 .

[0079] Specifically, such as Figure 6 As shown, the limiting portion 23 is located at the lower end of the multiple teeth 22, which is used to limit the degree of flipping of the two clamping joints 2 towards each other, thereby preventing the clamping joints 2 from flipping at too large an angle, causing the teeth 22 to disengage from the threads and the connection function to fail.

[0080] The number of teeth 22 on each clamping joint 2 is greater than or equal to four. When the stud 9 is pulled out, more threads are in contact with the teeth 22, which increases the pulling force and the stability of the connection between the fixture and the stud 9.

[0081] Example 4:

[0082] The fastener serves as an intermediate structure for setting the cable tie 7 at a certain fixed position. The cable tie 7 can be a connected fixed structure with the fastener. The hollow cable tie fastener of this embodiment is different from the above embodiment in that the fixing part 5 is sheet-shaped, and the surface of the fixing part 5 is used to connect the cable tie 7.

[0083] In another embodiment, if Figure 1 As shown, a connecting hole 6 is provided on the fixing portion 5 , and a cable tie 7 is detachably fixedly connected to the connecting hole 6 .

[0084] In the above structure, the sheet-shaped fixing portion 5 is high in strength. As a structure connecting the first support body 4 and the second support body 3, it not only enhances the overall strength of the fixer, but also provides a setting position for the cable tie 7, fixes the wire harness from one end of the fixer, and also ensures the stability of the wire harness fixation.

[0085] In addition, if Figure 1 As shown, the cross-sectional dimension of the fixing portion 5 is larger than the dimension of the virtual cross-sectional dimension formed by the cross-sectional dimensions of the first supporting body 4 and the second supporting body 3. While enhancing the strength of the fixing portion 5, when a carpet is laid on the vehicle body where the fixing stud 9 is fixed, the fixing portion 5 can contact the upper surface of the carpet or be located above the carpet after the rear fastener is installed, thereby limiting the carpet in place of the carpet fixing buckle. Specifically, the distance between the fixing portion 5 and the positioning ring 1 is equal to the thickness of the carpet or slightly larger than the thickness of the carpet.

[0086] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.
