Abstract

The utility model relates to a door stopper on fast moving objects, which mainly comprises a spring cover, a spring, a casing, a piston bush, a pull rod, a bolt, an inner pull handle and an outer pull handle. The bolt is fixed at the outer end of the pull rod; the inner end of the pull rod is fixed at the outer end of the piston bush; the outer end of the piston bush is limited through a supporting piece arranged inside the casing; the inner end of the piston bush is connected with one end of the limit spring; the other end of the spring is limited through the spring cover fixed on the casing; the inner pull handle and the outer pull handle are respectively fixed on the inner side and the outer side of the piston bush; a corresponding groove which can enable the pull handles to perform moving and limiting is arranged on the casing. The door stopper has the advantage that the bolt is adopted to stop the door, so that the deformation and the seizing of the door caused by the vibration of locomotive cars or passenger cars can be avoided. The two pull handles are arranged on two sides of the door, so that the door can be conveniently opened indoors or outdoors. The spring cover is in threaded connection with the casing, the spring force of the spring can be conveniently adjusted, the elastic force of the bolt can be adjusted according to the actual demand during the operation, the phenomenon that the door is seized and opened by force can not occur, and the spring can be more durably operated.

Description

Be used for the door knob device on the rapid moving object

Technical field

The utility model relates to a kind of door knob device, particularly a kind of door knob device that is used on the rapid moving object.

Background technology

What use on the door of the whole washroom on existing rapid moving object such as the locomotive is common spring latch lock, this bumps pearl if be used on the static door such as civilian construction comparatively reliable, but because the whole washroom on locomotive is in vibrational state always, be difficult to guarantee normal the use, have following defective: 1, locomotive vibration easily makes and bumps pearl distortion, stuck, and door can not be opened.2, because the handle on the door is less, bump open the door from the outside behind the pearl chucking very hard.3, because door is often stuck, has to resort to coercive measures and open, the repeated multiple times rear spring easily lost efficacy, and the door knob pearl can not be with door closure.

The utility model content

Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art and a kind of door knob device that is used on the rapid moving object is provided, make its be difficult for stuck, switch is easy.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

Be used for the door knob device on the rapid moving object, mainly form by spring cup, spring, overcoat, piston bush, pull bar, dead bolt, inside and outside handle, the pull bar outer end is dead bolt fixedly, the inner is fixed on the piston bush outer end, the piston bush outer end is spacing by the support chip that is provided with in the overcoat, one end of the inner of piston bush and limit spring joins, the other end of spring is spacing by fixing spring cup on the coat, inside and outside two sides of piston bush are fixed a handle respectively, and have on the coat and can allow handle move and spacing respective grooves.

Above-mentioned spring cup is connected with sleeve thread, and slots on spring cup.

Compared with prior art, advantage of the present utility model is:

Adopt dead bolt to remove to bump door, avoid being out of shape and make badge extremely not open because of the vibration of locomotive, passenger vehicle.

Adopt inside and outside two sides of door that two handles are set, can open easily in the indoor and outdoor.

Spring cup is connected with sleeve thread, and regulating spring elastic force can be regulated dead bolt elastic force according to the actual needs that uses, and the stuck phenomenon of prying open firmly can not occur easily, and it is more lasting that spring uses.

Therefore above-mentioned door knob device can be used on the express locomotive, boats and ships of fast moving.

Fig. 2 is the A-A sectional drawing of Fig. 1.

Fig. 3 is the upward view of the utility model embodiment.

Fig. 4 is the lateral view of the utility model embodiment.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, shown in Figure 3, be used for the door knob device on the rapid moving object, mainly by spring cup 1, spring 2, overcoat 3, piston bush 8, pull bar 5, dead bolt 6, handle 4, handle 7 is formed, dead bolt 6 is fixed on pull bar 5 outer ends, pull bar 5 the inners are fixed on the outer end of piston bush 8, the outer end of piston bush 8 is spacing by the support chip 33 that is provided with in the overcoat 3, one end of the inner of piston bush 8 and limit spring 2 joins, the other end of spring 2 is spacing by the spring cup 1 that is fixed on the overcoat 3, the fixing respectively handle 4 of inside and outside two sides of piston bush 8, handle 7, and on overcoat 3, have and can allow handle move and spacing

respective grooves

31,32.

Above-mentioned piston bush 8 and pull bar 5 can be single part, link together after also can separately making.

Limit spring one end of above-mentioned piston bush 8 is opened a cylindrical hole 81, and spring terminal places in the cylindrical hole 81, more convenient like this, better limit spring end.

Above-mentioned spring cup 1 and overcoat 3 have the screw edge of a knife 11 by being threaded on the spring cup 1, can rotate spring cup 1 by instrument like this, the elastic force of regulating spring 2 easily, thus adjust the coupling mechanism force of dead bolt.

Above-mentioned overcoat 3 its lateral surfaces also can be with installing plate 35 in addition, and installing plate is fixed on the door by installing hole on it 34 and screw, sees Fig. 4.
