Abstract
The utility model provides an observing door fastening device for a pavement roller. The utility model is characterized in that a rectangular boxlike fixing plate is embedded on the front side of the observing door; a folded plate is fixed on the back side of the observing door; fastening shaft with the screws are arranged on the fixing plate and the folded plate; a bolt with the matching thread hole is arranged on the fastening shaft; a spring which can make the bolt replacement is arranged on the fastening shaft; the outer end of the fastening shaft is hinged with a convertible handle in the fixing plate. The vibration and noise problems of the observing door generated by the vibration of the road roller are solved. The problem that the handle of the observing door is easy to be opened because of touching is solved. In addition the utility model also has the advantages of simple structure and easy production.
Description
Technical field
The utility model relates to a kind of road roller that is used for road construction, and especially a kind of road roller is observed door locking device.
Background technology
Development along with highway construction, vibratory roller is widely used, road roller when work water tank domestic demand has fills enough water and could guarantee the motor operate as normal, therefore but be arranged with the observation door of switch at water tank, its construction of switch of observing door mainly is that door handle drives dead bolt on the lock shaft and rotates an angle and dial on the doorframe limit and realize.The door switch of this structure can not be locked and be observed door, can produce vibration and noise along with the vibration of road roller steel wheel, even vibration makes dead bolt throw off the doorframe limit, and automatically open door, in addition, the handle of lock shaft outer end protrudes in a surface, also opens door when touching because of carelessness easily, and therefore existing door switch is neither attractive in appearance also dangerous.
Summary of the invention
The utility model provides a kind of road roller simple in structure, the friction noise to observe door locking device for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of road roller is observed door locking device, by door and doorframe thereof, be embedded in the rectangle fixed head on the door, be packed in the flap at a back side, be vertically mounted on rotatable lock shaft and axial restraint pin on fixed head and the flap, be installed in the dead bolt on the lock shaft, be installed in the handle of lock shaft outer end, and the locating piece that is packed in fixed door of doorframe margin and dead bolt fastening position is formed, be shaped on screw thread on the described lock shaft, the dead bolt that is connected with lock shaft is shaped on the screw that is complementary with it, an end also is installed on the lock shaft is fixed on its axle, the other end is fixed on the back-moving spring on the dead bolt.
The utility model can also adopt following technical measures:
Described rectangle fixed head is a rectangular box, and described handle is one and is hinged on the lock shaft outer end and is collapsible into handle in the rectangle fixed head.
Advantage and the good effect that the utlity model has are: because the dead bolt that has a back-moving spring and lock shaft for being threaded, not only make the observation door lock firmly but also with door be pressed on the doorframe, eliminated vibration and noise; Because the rectangle fixed head is a rectangular box, the handle that is hinged on the lock shaft outer end can be folded in the fixed head, not only attractive in appearance but also safety; The utility model also has advantage simple in structure, that be easy to make in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, observing the fixed head 5 that door 7 fronts are inlaid with rectangular box shape, the back side of observing door is fixed with flap 1, rotatable lock shaft 2 is installed on fixed head and flap, the inner of lock shaft is equipped with axial restraint pin 8, and the outer end of lock shaft is hinged with the handle 6 that may be folded in the fixed head.In order to realize observing the locking of door, be shaped on screw thread on the lock shaft, the dead bolt 3 that has matching threaded hole is installed on lock shaft by screw thread, the spring 4 that dead bolt is resetted also is installed on the lock shaft, one end of spring is welded on the dead bolt, its other end is welded on the lock shaft, and the twisting resistance that can utilize spring like this is the position of dead bolt fixedly.On doorframe 9, be equipped with and limit the locating piece 10 of observing door and dead bolt fastening position, as shown in Figure 2.
Operating principle:
At closing time, the handle 6 that turns clockwise drives lock shaft 2 and dead bolt 3 together turns clockwise, and when dead bolt contact locating piece 10, dead bolt stops operating, and lock shaft continues rotation, drives dead bolt and moves to doorframe 9, till compressing.
When opening the door, be rotated counterclockwise handle 6 drive lock shafts 2 and be rotated counterclockwise, unclamp dead bolt 3, dead bolt is got back to initial position under the twisting resistance effect of spring 4, observe door and be opened.
