Embodiment

In FIG, a kind of elastic lock automatically locked, itself and be required locking, lock post 3 corresponding matching that is loaded on door, it comprises base plate 2, locking plate 5 and a torsion spring 8.

In Fig. 1, Fig. 2, perpendicular in the end, side of base plate 2 being welded and fixed a retaining plate 1, base plate 2 also can adopt the bending of same plate body and become with retaining plate 1. In Fig. 1, Fig. 3, retaining plate 1 has fixed orifices 101, can be used for fixing the utility model and railway carriage wall.

In FIG, one end of base plate 2 is provided with the guide path 201 of an opening. As shown in Figure 1, guide path 201 gradually contracts to bottom land from opening, so that lock post 3 is slipped into smoothly by guide path 201 opening and this lock post 3 is locked in the bottom land of guide path 201.

In Fig. 1, Fig. 2, perpendicular in the end, side of locking plate 5 it is welded and fixed a lift plate 4. Equally, locking plate 5 also can adopt the bending of same plate body with lift plate 4 and become.

In FIG, being provided with a lock hook 501 in one end of locking plate 5, this lock hook 501, can be fixing by the lock post 3 hook lock slipping into guide path 201 bottom land in inverted L-shaped.

Slip into resistance for what reduce lock post 3, as shown in Figure 1, the outboard end limit of lock hook 501 is provided with the leading edge 502 of arc.

Opening lock hook 501 for ease of hand rotation locking plate 5, as shown in Figure 1, Figure 2, Figure 3 shows, the other end at lift plate 4 is provided with mobile division 401.

In Fig. 1, Fig. 2, at middle part vertical welding one stud 6 of base plate 2, this stud 6 passes the through hole 504 that locking plate 5 has and is rotated by locking plate 5 and be assemblied on stud 6, and the lift plate 4 on it is oppositely arranged with retaining plate 1.

For limiting lock stops the rotation scope of plate 5, as shown in Figure 1, the end side of locking plate 5 is provided with and opens spacing edge 503, when locking plate 5 rotates to certain angle around stud 6, open the end contact of spacing edge 503 with retaining plate 1, hinder locking plate 5 to be rotated further.

As shown in Figure 1, 2, torsion spring 8 is sleeved on stud 6, and it is by nut 7 axial limiting, and its first spring pin the 801, the 2nd spring pin 802 is separately fixed on one end of retaining plate 1, lift plate 4.

The utility model is when door closes, lock post 3 slips into from the guide path 201 of base plate 2 upper shed, slide along lock hook 501 leading edge 502, under the crowded support of lock post 3, locking plate 5 overcomes torsion spring 8 elasticity and rotates around stud 6, lock post 3 slips into guide path 201 bottom land by the gap of guide path 201, lock hook 501, and now locking plate 5 overturns under the effect of torsion spring 8, and lock hook 501 coordinates with guide path 201 will lock post 3 limitation locking; When door needs to open, manually pulling the mobile division 401 being arranged on lift plate 4, locking plate 5 overcomes torsion spring 8 elasticity and rotates around stud 6, and lock post 3 is skidded off by the gap of guide path 201, lock hook 501.

The utility model structure is simple, it may also be useful to convenient, and automatically, locking effect is good in locking.
