Abstract
The utility model relates to a width limit door, in particular to an adjustable width limit door which comprises two width limit door columns. At least one of the two width limit door columns is a movable door column which can be far from or close to the other door column. The movable door column is connected with a drive locking device in a transmission mode, and the drive locking device is used for enabling the movable door column to move to a corresponding place to be locked. By adjusting the distance between the two width limit door columns, the limit width can be adjusted, and the problem that the limit width of an existing width limit door is not adjustable is solved.
Description
Technical field
The utility model relates to width-limited door, particularly a kind of adjustable width-limited door.
Background technology
Road width-limited door is a kind ofly to limit oversize vehicle, lorry and be greater than the device that the object of certain width passes through, and is generally applied to the narrow places of traffic such as special traffic control, biotope, flood wall highway.Existing width-limited door mainly contains two kinds: a kind of is the structure door of steel-pipe welding, and another kind is the square pier that cement is built into.But all there is following shortcoming in above-mentioned two kinds of width-limited doors: 1. structure heaviness; 2. fixing rear its Max. Clearance _M. is unadjustable, can not regulate according to the actual requirements the Max. Clearance _M. of width-limited door.
Summary of the invention
The purpose of this utility model is to provide a kind of adjustable limiting door, the problem that can not regulate to solve the limit for width of existing width-limited door.
To achieve these goals, the utility model adopts following technical scheme: adjustable width-limited door, comprise two limit for width door pillars, at least one in these two limit for width door pillars be can away from near another movable door pillar, described movable door pillar is connected with the driving locking device for being moved to corresponding location locking.
Described driving locking device comprises the expansion bracket for driving movable door pillar to move.
Described expansion bracket is scissor angle adjustable frame.
One end of scissor angle adjustable frame is connected with movable door pillar, and the other end of scissor angle adjustable frame is connected with fixed leg, drives locking system also to comprise and is located at lock pin between scissor angle adjustable frame and fixed leg.
Described fixed leg is provided with the adjusting pin-and-hole for plug-in mounting lock pin, regulates pin-and-hole to have more than two, and each regulates pin-and-hole along arranging up and down.
Described movable door pillar is assemblied on bracing frame, and bracing frame is provided with movable pulley.
The beneficial effects of the utility model: because at least one in two limit for width door pillars of this adjustable limiting door is movable door pillar, by drive locking device can driving activity door pillar near or away from another limit for width door pillar, in the time that the Max. Clearance _M. between two limit for width door pillars meets the demands, drive locking device can make movable door pillar be locked in corresponding position.Therefore, adopt the utility model can regulate as required the distance between two limit for width door pillars, can realize the adjusting to Max. Clearance _M., solved the uncontrollable problem of Max. Clearance _M. of existing width-limited door.
Further, compared with driving slide block mechanism, expansion bracket has advantages of simple in structure and use cost is low.
Further, compared with the expansion bracket of direct rod shape, the intensity of scissor angle adjustable frame is higher, longer service life.
Further, one end of scissor angle adjustable frame is fixed on fixed leg by lock pin, can realize the locking location to scissor angle adjustable frame, thereby realize the locking location to movable door pillar, this locking locate mode has advantages of convenient operation and simple in structure, just can realize the control to shearing expansion link by manual operation.
Further, regulate pin-and-hole to have more than two, and arrange up and down, when lock pin inserts, by selecting different adjusting pin-and-holes, can realize the length adjustment of scissor angle adjustable frame, this regulative mode has advantages of convenient operation.
Further, movable door pillar is assemblied on the bracing frame with movable pulley, not only can reduce the moving resistance of movable door pillar, steady movement that can also guarantee activity door pillar.
Brief description of the drawings
Fig. 1 is the front view of the embodiment 1 of adjustable width-limited door of the present utility model;
Fig. 2 is the right view of the embodiment 1 of adjustable width-limited door of the present utility model.
Detailed description of the invention
The embodiment 1 of adjustable width-limited door of the present utility model, as shown in Figure 1-2: this is adjustable, and width-limited door comprises two limit for width door pillars 1, in these two limit for width door pillars 1, be can away from near another movable door pillar, movable door pillar is connected with the driving locking device for being moved to corresponding location locking.The spacing between two limit for width door pillars can be changed by this driving locking system, the adjusting of Max. Clearance _M. can be realized.
Drive locking device to comprise the expansion bracket for driving movable door pillar to move, this expansion bracket is scissor angle adjustable frame 3.One end of this scissor angle adjustable frame 3 is connected with movable door pillar, and the other end of scissor angle adjustable frame 3 is connected with fixed leg 4.Fixed leg 4 is provided with pile 5, downward-extension on pile 5, and fixed leg 4 is fixed on ground by ground post 5.Drive locking system also to comprise and be located at lock pin 6 between scissor angle adjustable frame 3 and fixed leg 4.Scissor angle adjustable frame comprises folding rod 31, and the end of the folding rod 31 of close fixed leg is provided with the installing hole for plug-in mounting lock pin 6.Fixed leg 4 is provided with the adjusting pin-and-hole 7 for plug-in mounting lock pin, regulates pin-and-hole 7 to have more than two, and each regulates pin-and-hole 7 along arranging up and down.Movable door pillar is assemblied on bracing frame 8, and bracing frame 8 is provided with movable pulley 9.
In the present embodiment, two limit for width door pillars are between left and right every setting, and it can move along left and right directions, and scissor angle adjustable frame can stretch left and right.Bracing frame 8 is tripod, and movable pulley 9 is positioned at the bottom of bracing frame 8 forward and backward both sides.In other embodiments, can also save bracing frame and movable pulley, can be provided with on the ground guide groove, movable post can be placed in guide groove.
