Abstract
The present invention provides switchboard locking device for rail vehicle capable of reducing vibration noise generated by the contact of rotary locking axis and bearing portion of a fixed main body. The fixed main body 1 is locked to the door 9 of a rolling stock distribution board storage box, the locking shaft 11 of a handle 2 is passed through a shaft hole 12 in the bearing part 10 of the fixed main body 1, and a clamp plate 5 is fitted around the rectangular shank 11a of the locking shaft 11. The handle 2 is rotatably attached to the fixed main body 1 by means of the middle flange 8 of the handle 2 and a nut 7 fitted around the locking shaft 11, and an O-ring 4 fitted in an annular groove 13 in the outer peripheral surface of the locking shaft 11 is pressed against the inner peripheral surface of the shaft hole 12.
Description
The present invention relates to the lock head device that a kind of door that is installed in distributing panel of railway vehicle is gone up, relative switchboard container moves door holder and lock.
Existing lock assembly for distributing panel of railway vehicle, the lock shaft of knob inserted lead in the axis hole of the fixed body bearing portion on being fixed in door, the stop steel plate is embedded on the square shaft of lock shaft, knob can be installed on the fixed body rotatably with the intermediate flange portion of knob and the nut that is embedded on the lock shaft.
Because when above-mentioned nut overtorquing, self rotation of lock shaft is impossible, so the degree of tightness of nut will suitably be adjusted, exists the gap between the bearing portion of the lock shaft of knob and fixed body.Pass when coming when rail truck travels, vibrates,,, destroyed the solemn silence in the vehicle so produce vibrating noise because the lock shaft of metal directly contacts with bearing portion.
Therefore, the purpose of this invention is to provide a kind of lock assembly for distributing panel of railway vehicle that can reduce the vibrating noise that produces owing to lock shaft and contacting of bearing portion.
If the reference number in the employing accompanying drawing describes, lock head device then of the present invention: fixed body 1 is fixed on the door 9 of distributing panel of railway vehicle container 16; The lock shaft 11 of knob 2 is inserted and is led in the axis hole 12 of fixed body 1 bearing portion 10; Stop steel plate 5 is embedded on the 11a of square shaft portion of lock shaft 11; Can be installed in knob 2 on the fixed body 1 rotatably with the intermediate flange portion 8 of knob 2 and the nut 7 that is embedded on the lock shaft 11; O shape circle 4 in the cannelure 13 that is embedded in lock shaft 11 outer peripheral faces is crimped on the inner peripheral surface of axis hole 12.
Fig. 1 is the front view of lock assembly for distributing panel of railway vehicle under the state of locking of one embodiment of the invention.
Fig. 2 is the vertical view of this locking device.
Fig. 3 is the rear elevation of this locking device.
Fig. 4 is the sectional view of the A-A line of Fig. 1.
Embodiment shown in the figure, knob 2 is configured in the central authorities of fixed body 1 front recess 21.In the bearing portion 10 of fixed body, be provided with the jut 17,18 of 2 restriction anglecs of rotation of diametrically contraposition, be fastened on the above-mentioned jut 17,18 owing to be embedded in the both ends of the anglec of rotation confinement plate 3 on the 11a of square shaft portion of lock shaft 11, the anglec of rotation of knob 2 is limited in 90 degree.Fixed body 1 is fixed on the door 9 by being embedded in 4 bolt 19 and nuts 20 in the installing hole 14.The locking pin seat 15 that the front end that is provided with stop steel plate 5 on the switchboard container 16 of rail truck can engage, separate.
As mentioned above, lock assembly for distributing panel of railway vehicle of the present invention, because will be embedded in O shape circle 4 in the cannelure 13 of lock shaft 11 outer peripheral faces of knob 2 is crimped on the inner peripheral surface of axis hole 12 of fixed body 1, so, when rail truck travels, even vibration passes come, the grade that does not also produce vibrating noise or vibrating noise between the bearing portion 10 of the lock shaft 11 of knob 2 and fixed body 1 reduces significantly, can guarantee the solemn silence in the rail truck.
In addition, because above-mentioned O shape circle 4 can produce appropriate frictional force between the bearing portion 10 of the lock shaft 11 of knob 2 and fixed body 1, therefore, lock shaft 11 can not rotate naturally because of the gravity of stop steel plate 5, the position that stop steel plate 5 can remain on the position of locking really or open lock.
