Abstract
The utility model relates to the technical field of rotary drilling rig covering part air spring opening and closing doors, in particular to a rotary drilling rig covering part air spring opening and closing door which comprises a door lock, a handle, a door, an air spring, a collision block and a door frame. The top end of the door is hinged to the top end of the door frame, the middle of the door is connected with the middle of the door frame through the air spring, the handle is arranged on the door, the door lock is mounted at the tail end of the door, and the collision block is mounted at the lower end of the door frame. The covering part door is quite convenient to open and close, the door is fixed at the maximum position and cannot fall down by locking the air spring, and a manual limit rod needed by a traditional mode is omitted.
Description
Technical field
The utility model relates to rotary drilling rig covering switching door technical field, especially a kind of rotary drilling rig cladding element gas spring switching door.
Background technology
Existing door-opening mode generally adopts hinge to lean on the manpower folding, and sight line is blocked in effort and horizontal folding meeting, repairs inconvenience, and area occupied is also larger.Realize that at present switching door mainly adopts the mode of accompanying drawing 2, accompanying drawing 3: door and doorframe are connected through the hinge, and realize 90 ° of opening and closing left and right.The folding of this kind mode door and hinge be manufactured with much relations, hinge as lubricated will be so that door folding difficulty and send the ear-piercing sound, open angle is also restricted, repairing to have good visual angle, when door reached maximum, the movement of gag lever post meeting lock door was if want to close to the doorstep, must manually gag lever post be shifted out from lockhole, be very much trouble.
The utility model content
In order to overcome the deficiency of existing technology, the utility model provides a kind of rotary drilling rig cladding element gas spring switching door.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of rotary drilling rig cladding element gas spring switching door, comprise door lock, handle, door, air spring, collision block, doorframe, top and the doorframe top of door are hinged, the door interlude is provided with air spring with the doorframe centre and is connected, door is provided with handle, the end of door is equipped with door lock, and collision block is equipped with in the doorframe lower end.
The beneficial effects of the utility model are, the utility model is so that the folding of covering door becomes particularly convenient, the self-locking of air spring can not fall so that door is fixed on the maximum position, and it is larger to have saved manual gag lever post and folding angle that traditional approach needs.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of original open-close ways structure;
Fig. 3 is A-A segment structure schematic diagram among Fig. 2;
Among the figure, 1, door lock, 2, handle, 3, door, 4, air spring, 5, collision block, 6, doorframe, 11, original door, 12, hinge, 13, original doorframe, 14, gag lever post, 15, original door lock, 16, positioning seat
The specific embodiment
Structural representation of the present utility model such as Fig. 1, a kind of rotary drilling rig cladding element gas spring switching door, comprise door lock 1, handle 2, door 3, air spring 4, collision block 5, doorframe 6, top and doorframe 6 tops of door 3 are hinged, door 3 interludes are provided with air spring 4 with doorframe 6 centres and are connected, door 3 is provided with handle 2, and the end of door 3 is equipped with door lock 1, and collision block 5 is equipped with in doorframe 6 lower ends.
Automatically door 3 is slowly flicked by air spring 4 after opening door lock 1, when stroke reaches maximum, air spring 4 self-lockings also are fixed on eminence with door 3, the folding angle determines by choosing air spring and installation site, on the doorframe 6 air spring install hinge from swivel point more close to, the folding angle is larger, and general angle can reach 135 °.Close door such as need, hold handle 2 and get final product whole moving process light and fast downwards.
The utility model is so that the folding of covering door becomes particularly convenient, the back door of unblanking can be opened automatically up, as long as selected angle is suitable, just can obtain the larger visual field, the self-locking of air spring so that the door be fixed on the maximum position, can not fall, save the manual gag lever post that traditional approach needs, have good use value.
