Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-4, it is the steering steel wire fixing structure of the present invention, which comprises a steering steel wire 1 and a lens holder 2 connected to the steering steel wire 1. Two mounting holes 3 for mounting the steering steel wires 1 are symmetrically arranged in the lens bracket 2, and the mounting holes 3 penetrate through the lens bracket 2. The entrance of mounting hole 3 is provided with the fixed protrusion 4 that is used for the riveting to turn to 1 tip of steel wire, and the cross section of fixed protrusion 4 is preferred to be arc, is convenient for rivet. During the assembly, the one end fixing of turning to steel wire 1 sets up in mounting hole 3, carries out the riveting fixed on mounting hole 3 through fixed protruding 4 riveting to the tip of turning to steel wire 1.
More specifically, the mounting hole 3 includes a mounting portion 5 and a connecting portion 6 communicating with the mounting portion 5, the aperture of the connecting portion 6 is smaller than that of the mounting portion 5, and the outer diameter of the steering wire 1 is smaller than that of the connecting portion 6, so that the steering wire 1 can pass through the inside of the lens holder 2. In order to strengthen the connection strength between the steering steel wire 1 and the lens bracket 2 and avoid the falling of the steering steel wire 1, a steel wire fastener 7 is arranged on the end part of the steering steel wire 1, and the steel wire fastener 7 is clamped in the mounting hole 3. Preferably, the outer diameter of the wire fastening member 7 is smaller than the inner diameter of the mounting portion 5 and larger than the inner diameter of the connecting portion 6, so that the end portion of the steering wire 1 can be well clamped in the mounting hole 3, and the steering wire 1 is connected more firmly and cannot fall off.
Of course, the end part of the steering steel wire 1 can be knotted to form a fixing knot, and the fixing knot is clamped in the mounting hole 3, so that the steel wire fastening piece 7 does not need to be additionally arranged, parts are effectively reduced, and the cost is reduced while the installation is facilitated. Likewise, the outer diameter of the fixing knot is smaller than the inner diameter of the mounting portion 5 and larger than the inner diameter of the connecting portion 6, so that the end portion of the steering wire 1 can be well caught in the mounting hole 3. It is obvious by the above-mentioned scheme, the utility model discloses a fixed arch 4 is direct to be fixed steel wire fastener 7 or knot for it is fixed to turn to steel wire 1 easily installation, fixed easy operation, and the fastening is effectual.
