Example 1:

as shown in fig. 1 to 8, the present embodiment relates to a connecting assembly, which includes a base member 1 and a hook member 2 detachably connected to the base member 1, wherein the base member 1 and the hook member 2 are respectively provided with a first connecting portion 10 and a second connecting portion 20. The first connecting portion 10 and the second connecting portion 20 can be used for connecting a tire chain, which is described in embodiment 2.

As shown in fig. 3-5, two side walls of the base plate 11 of the base member 1 are bent upwards to form L-shaped bent portions 12, a sliding groove 13 is enclosed between the L-shaped bent portions 12 at two sides and the base plate 11 therebetween, and a notch 131 of the sliding groove 13 extends to the end of the base member 1; and the side wall of the slide groove 13 is constructed as a catching portion 14. In the above embodiment, the L-shaped bent portions 12 on both sides define the width C of the sliding groove 13, and define the height d of the sliding groove 13 in the thickness direction. As shown in fig. 7 and 8, the front end of the hook member 2 is constructed with a hook 21, and the hook 21 is a sheet body that is adapted to the sliding groove 13 in the thickness direction, that is, the finger hook 21 is constructed as a sheet body having a thickness slightly smaller than the height d of the sliding groove 13. A clamping groove 22 is formed on one side end part of the clamping hook 21, and a hook part 23 is formed on the clamping hook 21 at the outer end of the clamping groove 22; and, the end corner of the outer end of the hook 21 far away from the hook part 23 is constructed into a circular arc section 24 which is opened towards the card slot 22.

The width C of the sliding groove 13 is smaller than the width a of the hook 21 but larger than the distance b between the bottom of the locking groove 22 and the other side wall of the hook 21, and in the process of connecting the hook member 2 to the base member 1, the width C of the sliding groove 13 is smaller than the width a of the hook 21, so that the hook 21 cannot be directly inserted into the sliding groove 13 from the notch 131 along the length direction. The end corner of the outer end of the hook 21 far from the hook 23 is configured as an arc section 24 with an opening facing the slot 22, and the arc section 24 is configured to enable the hook 21 to extend into or withdraw from the sliding slot 13 from the notch 131 only in an inclined state that the arc section 24 is attached to the inner side wall of the slot 22, as shown in fig. 2. Because the width C of the sliding groove 13 is greater than the distance b between the bottom of the clamping groove 22 and the other side wall of the clamping hook 21, the hook member 2 is righted after the hook part 23 is positioned in the sliding groove 13, so that the clamping part 14 can be positioned in the clamping groove 22, and the hook part 23 hooks the inner side end of the clamping part 14; the base component 1 and the hook component 2 are connected and fixed.

Due to the above-described structural and dimensional restrictions, the hook member 2 can be disengaged from the base member 1 only in the above-described tilted state, and the base member 1 and the hook member 2 can be surely connected without disengagement in the case of non-manual operation.

In a further aspect, an elastic component 3 is disposed on the base member 1. When the clamping part 14 is positioned in the clamping groove 22 or the hook 21 is released from the clamping part 14, the elastic part 3 can act on the hook 21 to limit the hook 21 from being released from the clamping part 14. In the scheme, the elastic part 3 is arranged on the base component 1, so that the hook 21 is further limited to be separated from the clamping part 14, and the base component 1 and the hook component 2 are ensured not to be separated. In a specific embodiment, the elastic component 3 is an elastic piece connected and fixed on the base member 1, and an elastic bayonet 32 is formed between an elastic end 31 of the elastic piece and the base member 1. When the fastening portion 14 is positioned in the fastening groove 22, the elastic end 31 of the elastic piece and the base member 1 are located at two sides of the thickness direction of the fastening hook 21, and the elastic piece elastically supports against the arc section 24 of the fastening hook 21. In this scheme, an elastic bayonet 32 is formed between the elastic piece and the base member 1, so that the hook 21 is located in the elastic bayonet 32, and the elastic piece can be elastically supported on the arc section 24 of the hook 21. Thereby ensuring that the base member 1 and the hook member 2 do not disengage.

In a further embodiment, the bottom caliber e of the card slot 22 is greater than the opening caliber f thereof, and the length g of the clamping area 141 of the clamping portion 14 is greater than the opening caliber f of the card slot 22 but less than the bottom caliber e of the card slot 22. The engaging portion 14 is inserted into the engaging groove 22 in an inclined state. In a specific scheme, the outer side wall of the clamping groove 22 is configured to be inclined gradually outwards from the open end to the bottom, the bottom of the clamping groove 22 extends towards the inner side end to form a limiting bayonet 221, and the caliber of the limiting bayonet 221 is slightly larger than the thickness of the clamping area 141 of the clamping portion 14. When the clamping portion 14 is positioned in the clamping groove 22, a part of the clamping portion 14 extends into the limiting bayonet 221. In this technical solution, the clamping groove 22 is configured in a shape with a large bottom caliber e and a small opening caliber, the length g of the clamping area 141 of the clamping portion 14 is greater than the opening end of the clamping groove 22, so that the clamping portion 14 cannot be directly loaded into or separated from the opening of the clamping groove 22, and one end of the clamping portion must be loaded into or withdrawn from the clamping groove 22 first, so that the connection stability of the base member 1 and the hook member 2 can be ensured.

a second object of the present invention is to provide an anti-skid chain, which comprises a chain body and a connecting assembly. The chain body comprises an outer side chain, an inner side chain and a plurality of transition chains connected between the outer side chain and the inner side chain. The coupling assembly is as described in example 1, and the base member 1 and the hooking member 2 are respectively coupled to both end portions of the outer side chain. The base member 1 and the hook member 2 are provided with a first connecting portion 10 and a second connecting portion 20, two end portions of the outer side chain are respectively connected to the first connecting portions 10 of the base member 1 and the hook member 2, and the second connecting portions 20 of the base member 1 and the hook member 2 are respectively connected to a transition chain.
