The specific embodiment
With reference to Fig. 1, the first embodiment of the present invention provides a kind of shell latch assembly 10, and it comprises the first lock mounting portion 12, the second lock mounting portion 14, hinge components 16, impaction plate 18, shock plate Connection Element 20, locking nut 22, cam pin 24 and connecting pin 26.
In this example, the first lock mounting portion 12 and the second lock mounting portion 14 comprise the first and second mounting discs separately. Mounting disc 12,14 is common forms spring lock collar, and is set up on the lid and main body that lays respectively at shell.Each mounting disc 12,14 is set up the (not shown) of hole separately that is arranged in shell (not shown), so that mounting disc 12,14 can evenly be mounted with a surface of shell substantially.
Shell latch lock 10 also comprises installation elements 30 and mount pin 32.Installation elements 30 is located in the second mounting disc 14 and is set to receive mount pin 32.Hinge components 16 comprises hold-down hook 34 and the hole 36 that is located at its one end.Hold-down hook 34 arranges around mount pin 32, so that hinge components 16 is mounted for pivoting action.
Shock plate Connection Element 20 is mounted for linear movement mutually on hinge components 16.Shock plate Connection Element 20 is provided with link slot 38 and cam path 40.Substantially longitudinally extending and the basic horizontal expansion of cam path of link slot 38.On shock plate Connection Element 20, one end relative with hold-down hook 34 is provided with and impacts plate hook 44.When shock plate Connection Element 20 is when closing locked position, hook 44 is mounted for being connected with impaction plate 18 by the hole 28 of impaction plate 18.
Shell latch assembly 10 also comprises several rivets 46.
In use, the locking nut 22 that shell latch assembly 10 manually rotates with brake key 42 by user is operated.The rotation of locking nut is the linear movement of shock plate Connection Element 20 between locked position and extended position by the conversion of motion of the cam pin 24 in cam path 40.During locking nut 22 rotations, connecting pin 26 moves along link slot 38.
The second embodiment of the present invention provides a kind of shell latch assembly 50 as shown in Figures 2 and 3.The shell latch assembly 50 of the present embodiment is similar to the shell latch assembly 10 of the first embodiment, and has following modification.Identical label is preserved for corresponding feature.
In the present embodiment, on hinge components 16, be provided with circular retaining hole 52.Cam pin 24 and connecting pin 26 are all set to through the retaining hole that limits their motion.
Be arranged on a pair of spring 58 to hinge components 16 rotatable motions.Spring is mounted for that hinge components is applied to tension force makes 20 biasings of shock plate Connection Element enter the position that is locked.
Fig. 3 shows shock plate Connection Element 20, and from the position of stretching, (Fig. 3 is the motion conditions to the position (Fig. 3 d) of locking by centre position (Fig. 3 b and Fig. 3 c) a).In the position of stretching, connecting pin 26 is positioned at one end of link slot 54, and cam pin 24 is positioned at one end of closing on link slot of cam path 56.Along with the rotation of locking nut 22, cam pin 24 is moved toward the far-end of cam path, and the position of connecting pin 2 along link slot wherein between point (Fig. 3 b) mobile.Then, the rotation of locking nut makes cam pin away from the far-end of cam path, returns to further (Fig. 3 c) motion along link slot to its other end of the position of connecting pin 26 to the direction of link slot.In the position of locking, cam pin 24 is got back to its original position in cam path 56, and is close to link slot 54, and connecting pin is positioned at one end relative with its original position in link slot.
The fourth embodiment of the present invention provides shell latch assembly 60, and its part-structure as shown in Figure 4 and Figure 5.The shell latch assembly 60 of the present embodiment is similar with the shell latch assembly 50 shown in Fig. 3 to Fig. 2, and has following modification.Identical label is preserved for corresponding feature.
In the present embodiment, cam path 62 has a holding element 64, its end towards and be close to link slot 54.Holding element is the brief summary 64 that the wall from cam path 62 stretches out.Holding element is arranged for and keeps cam pin in one end of cam path and therefore keep shock plate Connection Element at its locked position.Thereby holding element 64 can prevent shell latch lock 60, for example vibrate or knock down and surprisingly opened.
As shown in Figure 5, in use, cam pin 24 is upwards crossed Bing Zigai position, maintained position that brief summary 64 enters the end that is positioned at cam path out.When shock plate Connection Element 20, from the position of stretching, (Fig. 4 a) enters the position (Fig. 4 e and Fig. 5 c) being locked, cam pin 24 enters downwards and is held position from a side of brief summary 64 (Fig. 5 a) upwards, crosses brief summary 64(Fig. 5 b) and from the opposite side (Fig. 5 c) of brief summary.From being held shifting out of position, be contrary, as shown in the order of Fig. 5 c to 5a.
