Abstract

The utility model relates to a component structure of a vehicle rim, in particular to a rim lock ring safety device, which comprises a metal ring with a notch. An inner peripheral surface of the metal ring is provided with an annular projection capable of matching with an annular clamp groove on a rim, two ends at the notch of the metal ring are respectively provide with a connecting surface, the connecting surfaces are located on the same plane, each connecting surface is provided with a threaded hole, a connecting plate is lapped between the two connecting surfaces and provided with a mounting hole corresponding to the threaded holes on the two connecting surfaces, and the connecting plate is fixedly connected with the two ends of the metal ring through nails penetrating at the mounting hole and the threaded holes. The rim lock ring safety device is convenient in installation, not easy to fall and fine in safety.

Description

The rim lock safety device

Technical field

The utility model relates to a kind of block construction of vehicle rim, specifically is a kind of rim lock safety device.

Background technology

Retainer is the parts of vehicle rim, it is generally a wire loop with fracture, its inboard is provided with the projection of the annular that matches with the annular slot of wheel rim end, be installed in the elasticity of utilizing wire loop self and annular projection is snapped onto in the annular slot on the wheel rim obtain the location, its effect stops that tire deviates from wheel rim.In this structure, retainer relies on the elastic positioning card of self tight fully, and when long-time use, the retainer easy deformation comes off and lost efficacy; In addition, retainer may not snap in draw-in groove fully because of misoperation makes it when installing, and may make the retainer ejection like this and personnel are on every side damaged behind inboard inflation of tire, thereby have potential safety hazard.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of easy for installation, difficult drop-off, rim lock safety device that safety is good are provided.

Rim lock safety device of the present utility model includes a wire loop with fracture, has the annular projection that can match with the annular slot on the wheel rim on the inner peripheral surface of wire loop; Incision position at wire loop, two ends of wire loop have joint face in the same plane respectively, have tapped bore on the joint face, be overlapped with a connecting panel between two joint faces, connecting panel be provided with two joint faces on the corresponding mounting hole of tapped bore, two ends of connecting panel and wire loop are connected and fixed by the screw of cross-under at described mounting hole and tapped bore place.

Mounting hole on the described lap plate is a waist shaped hole.

The utility model has the advantages that: can fix by connecting panel after 1, retainer is in place, prevent that it from deviating from, guarantee the reliability that uses; 2, because the matching relationship of connecting panel and wire loop end, when having only annular projection on the wire loop correctly to snap in the annular slot on the wheel rim, connecting panel could be installed smoothly, thereby the hidden danger that wire loop does not snap in fully when having avoided installation has guaranteed safety.

The specific embodiment

As shown in the figure, this device includes a wire loop 1 with fracture, has the annular projection 2 that can match with the annular slot on the wheel rim on the inner peripheral surface of wire loop; Incision position at wire loop, two ends of wire loop have joint face in the same plane 3 respectively, have tapped bore 4 on the joint face, be overlapped with a connecting panel 5 between two joint faces, connecting panel be provided with two joint faces on the corresponding mounting hole 6 of tapped bore, two ends of connecting panel and wire loop are connected and fixed by the screw 7 of cross-under at described mounting hole 6 and tapped bore 4 places.Mounting hole 6 on the lap plate is a waist shaped hole, with the size that struts that reduces the screw installation difficulty and regulate wire loop.

Claims

1. rim lock safety device, include a wire loop (1) with fracture, has the annular projection (2) that can match on the inner peripheral surface of wire loop with the annular slot on the wheel rim, it is characterized in that: at the incision position of wire loop, two ends of wire loop have joint face in the same plane (3) respectively, have tapped bore (4) on the joint face, be overlapped with a connecting panel (5) between two joint faces, connecting panel be provided with two joint faces on the corresponding mounting hole of tapped bore (4) (6), two ends of connecting panel and wire loop are connected and fixed by the screw (7) of cross-under at described mounting hole and tapped bore place.

2. rim lock safety device according to claim 1 is characterized in that: the mounting hole on the described lap plate (6) is a waist shaped hole.
