Description

Technical Field

[0001] This utility model relates to an ISOFIX connector knurled crimp screw. Background Technology

[0002] An ISOFIX connector is a device for securing child safety seats to a vehicle. ISOFIX is a new standard for installing child seats in cars, making installation quick and easy. Child seats equipped with ISOFIX can be easily secured to the car's ISOFIX connectors, increasing safety.

[0003] ISOFIX connectors typically include a connector housing, a connection mechanism, and a button assembly. The connector housing is responsible for securing it to the child seat, while the connection mechanism connects to the rigid connection part on the car seat. Usually, screws are fixed on the connector housing to secure it to the child seat. Currently, most screws on the connector housing are fixed by welding, which is not only unsightly but also time-consuming and material-costing. Utility Model Content

[0004] This utility model provides an ISOFIX connector knurled crimp screw.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] An ISOFIX connector knurled rivet screw includes a connector housing. The bottom surface of the connector housing has a first through hole, and the top surface has a second through hole. The diameter of the first through hole is larger than the diameter of the second through hole. A fixing screw is provided at the second through hole. The fixing screw includes a nut and a screw rod. The top of the screw rod has a knurled portion. The distance from the outermost end of the knurled portion to the central axis of the screw rod is greater than the radius of the second through hole and less than the radius of the first through hole. The fixing screw protrudes from the inside of the second through hole.

[0007] Preferably, the connector housing is a hollow square tube, and through sliding holes are provided on both the left and right sides of the tube wall. The sliding holes are used to connect the button assembly. A connecting mechanism is provided inside the connector housing, and the button assembly passes through the sliding holes and is connected to the connecting mechanism.

[0008] Preferably, an upwardly extending annular protrusion is provided on the top outer side of the second through hole.

[0009] Preferably, the lower end of the knurled portion is provided with threads.

[0010] Preferably, the knurled portion is provided with knurling that is vertically arranged around the screw, and the height of the knurling protrusion is higher than that of the thread.

[0011] Preferably, the distance from the outermost end of the thread to the central axis of the screw is less than the radius of the second through hole.

[0012] Preferably, the thread is located on the top outer side of the connector housing.

[0013] Compared with the prior art, the ISOFIX connector knurled rivet screw of this utility model has a knurled part on the top of the screw shank. The diameter of the knurled part is larger than the diameter of the second through hole. The top of the screw passes through the first through hole and then the second through hole. Since the diameter of the knurled part is larger than the diameter of the second through hole, the knurled part is pressed into the second through hole by external force. The screw is fixed to the connector housing by friction. The thread is located on the top of the connector housing, and a child safety seat can be fixed at the top of the screw. The fixing method of the screw is simple and can save a lot of costs. Moreover, the appearance after fixing is beautiful, which can improve the consumer experience. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 3 As shown, the ISOFIX connector knurled rivet screw includes a connector housing 1. The interior of the connector housing 1 is a hollow square tube. The left and right sides of the tube wall of the connector housing 1 are provided with through sliding holes 11. The sliding holes 11 are used to connect the button assembly 3. The connector housing 1 is provided with a connecting mechanism. The button assembly 3 passes through the sliding holes 11 and is connected to the connecting mechanism.

[0019] The connector housing 1 has a first through hole 12 on its bottom surface and a second through hole 13 opposite to the first through hole 12 on its top surface. The second through hole 13 has an upwardly extending annular protrusion 131 on its top outer side. The diameter of the first through hole 12 is larger than the diameter of the second through hole 13.

[0020] A fixing screw 2 is provided at the second through hole 13. The fixing screw 2 includes a nut and a screw rod. The top of the screw rod is provided with a knurled part 21, and a thread is provided below the knurled part 21. The knurled part 21 is provided with knurling that is vertically arranged around the screw rod, and the height of the knurling is higher than that of the thread. The distance from the outermost end of the knurled part 21 to the central axis of the screw rod is greater than the radius of the second through hole 13 and less than the radius of the first through hole 11. The distance from the outermost end of the thread to the central axis of the screw rod is less than the radius of the second through hole 13.

[0021] The fixing screw 2 is installed by passing it upwards from the bottom of the first through hole 12 through the first through hole 12 and the second through hole 13. After the thread of the fixing screw 2 passes through the second through hole 13, the knurled part 21 is pressed into the annular protrusion 131 of the second through hole 13 by external force. The fixing screw 2 is fixed on the connector housing 1 by friction. The thread is located on the top outer side of the connector housing 1. A child safety seat can be installed and fixed on the upper end of the fixing screw 2. The fixing method of the fixing screw 2 is simple and can greatly save material and production time costs. The appearance after fixing is also beautiful.

[0022] This utility model of ISOFIX connector knurled rivet screw features a knurled portion 21 on the top of the screw shank of the fixing screw 2. The diameter of the knurled portion 21 is larger than the diameter of the second through hole 13. The top of the fixing screw passes through the first through hole 12 and then the second through hole 13. Since the diameter of the knurled portion 21 is larger than the diameter of the second through hole 13, external force is used to press the knurled portion 21 into the second through hole 13. Friction force fixes the fixing screw 2 onto the connector housing 1. The thread is located on the top of the connector housing 1, allowing for the fixing of a car seat at the top of the fixing screw 2. The fixing method of the fixing screw 2 is simple and saves a lot of costs. Moreover, the appearance after fixing is aesthetically pleasing, which can improve the consumer experience.
