Embodiment
Embodiment one
A kind ofly be used between external module and matrix fixing quick locking structure, to shown in Figure 5, be the single shaft locking structure, comprise the connecting head 11 that is arranged on the external module 1 and be arranged on connecting base 2 on the matrix as Fig. 1.
As shown in Figure 4, external module 1 is a cuboid, and its connecting head is a rectangle joint 11, is processed with lock 12 at the two ends of rectangle joint 11.
As shown in Figure 3, matrix is provided with connecting base 2, and the shape of connecting base 2 is identical with the shape of external module 1, and the rectangle joint 11 that makes its inner space can hold external module 1 is put into, and the inner space of connecting base 2 is surrounded by rectangle support 21.The bottom of connecting base 2 is fixed with a supporting base 22, has support slot 221 on the axle supporting base 22.Live axle 3 is installed in the support slot 221.One end and the middle part of live axle 3 are installed with main card hook 32 respectively, and the other end of live axle 3 is equipped with spanner 6 by driveshaft 31.The intermediate section that is positioned at two grabs 32 of live axle 3 is that cross section is orthohexagonal hexagonal rod 311.The compressing member 5 that is positioned at live axle 3 tops has smooth section 51 and bending section 52, and wherein bending section 52 is an elastic member.
As Fig. 4, shown in Figure 5, smooth section 51 of compressing member 5 is fixedly mounted on live axle 3 in the support slot 221 by screw 7, and the surface engagement of its bending section 52 and hexagonal rod 311 compresses an outerplanar of hexagonal rod 311, thereby stop any rotation of live axle 3, play spacing effect.
As shown in Figure 1 and Figure 2, during assembling, rectangle joint 11 is aimed at connecting bases 2 puts into, pull spanner 6, drive live axle 3, the hexagonal rod 311 on the live axle 3 overcome compressing member bending section 52 elastic pressure and rotate, make main card hook 32 fasten lock 12.At this moment, compressing member 5 cooperates with the another side of hexagonal rod 311, thereby compresses live axle 3.When needs separate external module 1 with matrix, only spanner 6 need be pulled toward opposite directions, make main card hook 32 and lock 12 break away from, thereby take off external module 1 from fitting seat 2.
In this embodiment, because the part drive axle segments adopts hexagonal rod to be processed into, load-carrying surface on the live axle comprises first load-carrying surface and second load-carrying surface, both are two adjacent sides of hexagonal rod, the bending section 52 of compressing member is pushed down first load-carrying surface during locking, the bending section 52 of compressing member is pushed down second load-carrying surface during release, makes that the rotation angle of spanner 6 is that work angle between grab 32 and lock 12 releases, the locking is 60 °.The outer side surface of hexagonal rod 311 and the bending section of compressing member 52 match, and have both realized 60 ° operating space, limit again and open and lock two positions.Different work angles is realized in adjacent two sides that also can adopt other many ribs rod or have a several angle.Certain first load-carrying surface and second load-carrying surface also can be non-conterminous, and the centre is provided with the smooth surface of transition, increase work angle; First load-carrying surface and second load-carrying surface can constitute for various planes, curve form or by the discontinuous strong point, line or face.
During operation, needing on spanner 6 application of force to overcome the elastic force of bending section 52 could switching position, swift to operate and not hard, has guaranteed to open and lock stability separately, can not cause because of reasons such as vibrations to get loose.The bending section 52 of compressing member adopts different bending angles can form different impacting forces, thereby also provides different folding dynamics for spanner 6.Smooth section 51 of compressing member cooperates with support slot 221, for live axle 3 provides the rotating support face, thereby need not increase parts more in addition.The opening of rectangle support 21 forms cavity, dock with external module 1, plays guiding and location, and design can guarantee the less gap of rocking under the single shaft situation than the guiding stroke of length.
Embodiment two
A kind ofly be used between external module and matrix fixing quick locking structure, to shown in Figure 8, be the twin shaft locking structure as Fig. 6.
Itself and embodiment one difference are, also comprise driven shaft 4, and follower lever 41 two ends of driven shaft 4 fixedly are equiped with secondary grab 42 respectively; The two ends of the rectangle joint 11 of external module 1 are provided with two groups of locks 12, cooperate with main card hook 32, secondary grab 42 on live axle 3 and the driven shaft 4 respectively.The structure of crank block type is used in transmission between live axle 3 and the driven shaft 4, and the main card hook 32 on the live axle 3 is provided with driving pin 33, has sliding-groove 421 on secondary grab 42.Main card hook 32 is along with live axle 3 rotates, and driving pin 33 is also sliding in the sliding-groove 421 at secondary grab when live axle 3 rotates, and this is in transmission connection and drives driven shaft 4 backward rotation, makes main card hook 32 and secondary grab 42 realize opening synchronously and locking.
Adopt the structure of twin shaft four grabs of this embodiment can realize more firm connection, and use simple, convenient.
Embodiment three
A kind ofly be used between external module and matrix fixing quick locking structure, be the twin shaft locking structure, itself and embodiment one difference are, live axle comprises two, one group of grab respectively is installed respectively on it, the opening direction of two groups of grabs is opposite, and cooperates respectively with two groups of locks on the external module.Compressing member comprises two, cooperates with two live axles respectively to compress.One end of each live axle is equipped with spanner, and is positioned at the two ends of fitting seat.When external module and matrix assembling, external module alignment fitting seat is put into, and pulled the spanner at fitting seat two ends successively, the grab on two live axles can be fastened successively two groups of locks on the external module, thereby realize connecting.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
