Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
The structure of a kind of mangetic core assembly two-bolt lock fixing apparatus of the present utility model as shown in Figure 1, Figure 2, Figure 3 and Figure 4, comprises spool 1, spring 3 and spring fixed seat 4; The lower end of described spring fixed seat 4 is provided with low groove 43, the centre of described spring fixed seat 4 is provided with aperture 41, described spring fixed seat 4 is also provided with a macropore 42, described macropore 42 is arranged on the side of described aperture 41, partially overlaps between described macropore 42 and aperture 41; The joint 11 that described spool 1 comprises top 10, bottom 12 and is arranged between top 10 and bottom 12, the radius at described top 10 is greater than the radius of aperture 41, and the radius at described top 10 is less than the radius of described macropore 42; In addition, also comprise fixed plate 2, the centre of described fixed plate 2 is provided with matching hole 21, the side of described matching hole 21 is provided with the mounting groove 23 be connected with outside, described joint 11 is through described matching hole 21, described fixed plate 2 is arranged in described low groove 43, and described spring 3 is arranged between described fixed plate 2 and described bottom 12, and described fixed plate 2 enters described macropore 42 for preventing described joint 11.
Wherein, described fixed plate 2 is fixedly mounted in described low groove 43, and the difference of the radius size of described matching hole 21 and the radius size of described joint 11 is less than the distance of the described aperture 41 hole heart to the described macropore 42 hole heart.The restriction of above distance ensures that, after fixed plate 2 is installed, spool 1 can not to move in macropore 42 thus to come off from aperture 41.The upper end of described spring fixed seat 4 is also provided with upper groove 45.Upper groove 45 may be used for the placement at top 10.
