Abstract

The utility model discloses a safety lock for an engine hood, which comprises an installing bracket, an opening handle, a lock hook, a torsional spring, a safety fixing plate and a pullback spring. The utility mode is characterized in that a pin shaft penetrates through the opening handle, the torsional spring and the safety fixing plate to be riveted with the lock hook; one end of the torsional spring is clamped on the opening handle, and the other end is clamped on the safety fixing plate; the lower end of the pullback spring is fixed on the lock hood, and the upper end is fixed on the installing bracket; the opening handle is vertically arranged in grizzly screens of an engine; when the engine hood is opened, the opening handle extends out of the grizzly screens of the engine; and when the engine hood is closed, the opening handle retracts into an engine bay. The utility model has the advantages of convenient opening, convenience, beautiful appearance, practicality and the like.

Description

The hood safety lock

Technical field

The utility model relates to a kind of motor protecgulum open system, relates in particular to the design of hood safety lock.

Background technology

Hood safety lock different automobile types adopts different structure designs at present, but the design of aspects such as its function and opening ways is similar substantially, Fig. 1 is typical two kinds, wherein the opening ways of Fig. 1 a is that open front and back, and the opening ways of figure b is opened about being, the position of present existing unlatching handle is shown in A part among Fig. 2, as can be seen from Figure 2, as present traditional main flow design, after hood is opened, need remove to touch the unlatching handle of hood safety lock with hand.May cause following problem like this:

May be when 1, hand touches the unlatching handle by scratch.

2, open inconvenience.Cause that the client complains.

Therefore, change the traditional design mode, provide a kind of unlatching easily the hood safety lock become the technical problem that those skilled in the art press for solution.

Summary of the invention

Technical problem to be solved in the utility model is under the condition that guarantees hood safety lock basic function, solves the user when opening the hood safety lock, can't observe a difficult problem of opening handle position.Provide a kind of simple in structure, open hood safety lock easily, to overcome the above-mentioned defective that prior art exists.

The technical scheme of the utility model technical solution problem is as follows:

A kind of hood safety lock comprises mounting bracket, opens handle, latch hook, torsion spring, insurance fixed head and extension spring, it is characterized in that, bearing pin passes unlatching handle, torsion spring, insurance fixed head and latch hook and is riveted together; One of torsion spring is connected to be opened on the handle, and the other end is connected on the insurance fixed head; Described extension spring lower end is fixed on the latch hook, and the upper end is fixed on the mounting bracket; Described handle is provided with perpendicular to the motor grid, and when hood was opened, described handle stretched out in the motor grid, and when hood was closed, handle was withdrawn in the enging cabin.

By above disclosed technical scheme as can be known, when hood U-shape lock button during with the closing of hood assembly, the U-shape lock button moves downward and strikes hood safety lock latch hook, when continuing to move downward, clash into mutually with the insurance fixed head, the insurance fixed head is subjected to bump and will travels forward, and drive unlatching handle 2 travels forward under the effect of torsion spring, thereby make handle when hood is closed, handle is hidden in the enging cabin, and external surface does not have handle and exposes; As a same reason, when hood was opened, the U-shape lock button moved upward, and discharged the insurance fixed head, and handle is ejected in grid, and personnel easy to use open.

The specific embodiment

Further specify the utility model below in conjunction with accompanying drawing.

Shown in Fig. 3,4, the utility model hood safety lock, comprise mounting bracket 1, unlatching handle 2, latch hook 3, torsion spring 4, insurance fixed head 5 and extension spring 6, it is characterized in that bearing pin 7 passes unlatching handle 2, torsion spring 4, insurance fixed head 5 and latch hook 3 and is riveted together; 4 one of torsion springs are connected to be opened on the handle 2, and the other end is connected on the insurance fixed head 5; Described extension spring 6 lower ends are fixed on the latch hook 3, and the upper end is fixed on the mounting bracket 1, and described handle 2 lower ends are provided with draw-in groove 21, and described torsion spring 4 one ends snap onto in the draw-in groove 21.

As shown in Figure 5, described handle 2 is provided with perpendicular to motor grid 8, and when one grade of lock was opened, hood was opened, and described handle 2 stretches out (Fig. 5 shown in the B handle position) in the motor grid, thereby is convenient to open; When hood 9 was closed, handle 2 was withdrawn in the enging cabin (as handle position shown in the C among Fig. 5), and the car load external surface does not have handle to expose.
