Description
Technical field
The present invention relates to a kind of railway freight-car side door self-locking device, belong to railway freight-car car door accessory technical field.
Background technology
At present, the mode of closing of railway freight-car side door is that the latch on the door shutting tail gate is that car door strip plate gets in the room of knocker, and the rotation locking plate that revolving door is buckled enters in the knocker groove, promptly pins car door.But because the vibrations of train and other factor affecting are rotated locking plate accident in knocker and deviate from, and car door is in runaway condition, be prone to take place major accident in actual use.The measure of generally taking is: at knocker and latch is that strip plate centre is thrown timber wedge into or used iron wire knocker to be bundled on the rotation locking plate; The rotation locking plate gap enlargement distortion of repeatedly using timber wedge that door is buckled; Can't continue to use; Use the iron wire binding to waste time and energy, operational difficulty during operation especially in the winter time or in the bad weather.
Summary of the invention
In order to overcome above-mentioned deficiency, the purpose of this invention is to provide a kind of railway freight-car side door self-locking device, this railway freight-car side door self-locking device has effectively solved the difficult problem that side door can't self-locking, uses simple, convenient.
The technical solution adopted for the present invention to solve the technical problems is: railway freight-car side door self-locking device is made up of spring, time locking bar, lock, base, bolt, alignment pin, lock body, hinge, steel ball, last locking bar, and lock is circular, and its lower end is provided with base; The centre of base is provided with through hole; The lock upper end is provided with hinge, and the upper end of hinge is respectively equipped with the hole of bead that matches with steel ball, and the lower end is provided with the annular groove around alignment pin; One end of lock body is provided with down locking bar and last locking bar; Be provided with the slotted hole that can place spring in the middle of the body of rod of following locking bar and last locking bar, be equipped with steel ball between the termination of spring and the hole of bead of hinge, the other end of lock body is provided with alignment pin; Lock body is installed on the hinge, is slided by alignment pin and locatees.
The invention has the beneficial effects as follows: the rotation locking plate that door is buckled pins and can unexpectedly eject, and uses fast, saves the activity duration, and is convenient, simple in structure, improves the traffic safety of railway freight-car.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is a railway freight-car side door self-locking device structural representation of the present invention.
Fig. 2 is a railway freight-car side door self-locking device side-looking structure chart of the present invention.
Fig. 3 is that railway freight-car side door self-locking device of the present invention uses sketch map.
Among the figure 1, spring, 2, locking bar down, 3, lock, 4, base, 5, bolt, 6, alignment pin, 7, lock body, 8, hinge, 9, steel ball, 10, go up locking bar, 11, knocker, 12, latch.
The specific embodiment
Like Fig. 1-shown in Figure 2, railway freight-car side door self-locking device by spring, down locking bar, lock, base, bolt, alignment pin, lock body, hinge, steel ball, go up locking bar and form, lock 3 is a circle; Its lower end is provided with base 4, and the centre of base 4 is provided with through hole, and lock 3 upper ends are provided with hinge 8; The upper end of hinge 8 is respectively equipped with the hole of bead that matches with steel ball 9; The lower end is provided with the annular groove around alignment pin 6, and an end of lock body 7 is provided with down locking bar 2 and last locking bar 10, is provided with the slotted hole that can place spring 1 in the middle of the body of rod of following locking bar 2 and last locking bar 10; Be equipped with steel ball 9 between the hole of bead of the termination of spring 1 and hinge 8; The other end of lock body 7 is provided with alignment pin 6, and lock body 7 is installed on the hinge 8, is screwed into annular groove slip location by alignment pin 6.
Its use is as shown in Figure 3; Base on the railway freight-car side door self-locking device 4 usefulness bolt are connected knocker 11 1 sides of car door, and following locking bar 2 is positioned at knocker 11 tops, will descend locking bar 2 and last locking bar 10 to rotate that a layback moves to car door outside; Following locking bar 2 rotates together with lock body 7; Steel ball 9 in the lock body 7 slides on hinge 8 and deviates from the hole of bead, and the knocker 11 on the car door can be opened at this moment, and latch 12 breaks away from knockers 11 can open car door; After the lorry loading, with closing of the door, latch 12 is spacing by knocker 11, and locking bar 2 rotates along hinge 8 together with lock body 7 under rotating, and will descend locking bar 2 bogie car knockers 11 tops, in the hole of bead that steel ball 9 gets in the hinges 8 under the effect of spring 1 knocker 11 is pinned.
