Accompanying drawing explanation
Fig. 1 is an embodiment's of the present utility model schematic diagram;
Fig. 2 is relevant fixed base and bar hole schematic diagram thereof embodiment illustrated in fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, an embodiment of the present utility model is, a kind of casing connects fast lock, and it comprises lock shaft 106; Described lock shaft one end arranges fixed block, the other end arranges hangs pin 101, between described fixed block and described extension pin, order arranges spring 105, fastening stud 104, for inserting outside the second fixed base 103, the rear rotation of the first fixed base 102 by described extension pin order, fixes; The bar hole of described fastening stud setting and described extension pin form fit, be used for through described extension pin, and described fastening stud extension arranges shank on the other hand, be used for rotating described fastening stud self, described second fixed base of fastening outside and described the first fixed base.For example, utilize like this screw-tightened principle, increase handle, realize and just can realize unclamping and fastening function of connected component without assistant tool.
Preferably, described casing connects in fast lock, and the pitch of described fastening stud is set to 4 to 8 millimeters.Preferably, described casing connects in fast lock, and the pitch of described fastening stud is set to 5 millimeters.Like this, rotate when mounted 70 to 120 degree, for example 90-degree rotation, just can realize unclamping and fastening function of connected component, in other words, by increasing pitch, for example pitch is 5MM, change conventional criteria pitch, realize rotation small angle and produce large stroke, thereby reduce the repeated work of rotation.
Preferably, as shown in Figure 1, described casing connects in fast lock, and described lock shaft also arranges labeling section 107, for the sense of rotation of fastening stud described in mark.For example, as shown in Figure 1, described lock shaft also arranges two labeling section, indicates the direction that screws and get loose of described fastening stud, in order to avoid the setter blindness application of force causes damage parts.
Preferably, described casing connects in fast lock, and described lock shaft, at described fastening stud place, arranges two orthogonal buckle positions.For example, preferred, fastening stud is without assistant tool, and 90-degree rotation just can be realized unclamping and fastening function of connected component, before 90-degree rotation, with afterwards, lays respectively in buckle position, is convenient to keep original position not move, convenient control.
Preferably, described casing connects fast lock and also comprises the second fixed plate and the first fixed plate that are set in sequence between described fastening stud and described extension pin, and described the first fixed plate arranges respectively same described bar hole with described the second fixed plate.Like this, can protect described the second fixed base and described the first fixed base, for example, the second fixed plate is arranged between described fastening stud and described the second fixed base, and the first fixed plate is arranged between described the first fixed base and described extension pin; Preferably, the one side that the second fixed plate contacts described the second fixed base arranges rubber layer, and the one side that the first fixed plate contacts described the first fixed base arranges rubber layer.
Preferably, described casing connects fast lock and also comprises described the second fixed base and described the first fixed base.Like this, can be used as an over all Integration in each casing or between each casing, convenient carrying and installation.
