Abstract
The utility model relates to a compound mitre mode double-door protecting device for saws; particularly, which is a device protecting saw teeth in a non-operation state all the time and ensuring safety of operators; a front movable protecting cover arranged on a frame is movably connected with a connection rod; the other end of the upper connection rod is formed by a middle connection rod movably connected to the frame and a lower connection rod which is movably connected with a rocker; a rear movable protecting cover with an upper connection rod is also arranged at the position of the front movable protecting cover; the upper connection rod is connected with the upper connection rod on the front movable protecting cover. The front and the rear movable protecting covers are concentrated on the frame, which enlarges operation space; thus, the utility model has the advantages of reasonable arrangement, and safer and more reliable operation and use.
Description
The utility model relates to a kind of portable electric power tool, and the major part protective cover of compound saw particularly a kind ofly can protect the sawtooth of off working state all the time, guarantees the cut sth. askew protector of pattern double door of operator's compound saw safe in utilization.
The existing compound saw of Shi Yonging, has only a preceding flexible blade guard, but it has also fixed a fixed blade guard on the rear position of work top, and one end be connected with rocking bar on the compound saw, matched by preceding flexible blade guard and fixed blade guard, the sawtooth that exposes during with off working state protects.Because of fixed blade guard is arranged, occupied the confined space on the work top, blocked operator's sight line simultaneously again, make work top seem crowded.
The purpose of this utility model is to provide a kind of compound saw pattern double door protective device of cutting sth. askew, and it is simple in structure, has increased the operating space of work top, uses safer, reliable.
The utility model is achieved in that the compound saw pattern double door protective device of cutting sth. askew, flexibly connect by the preceding flexible blade guard and the last connecting rod that are installed on the framework, the in addition end of last connecting rod is by being movably connected in the middle connecting rod on the framework and connecting to form with lower link that rocking bar flexibly connects, and the flexible blade guard place also connects a back flexible blade guard that has a connecting rod before described, described last connecting rod flexible connection of going up on connecting rod and the preceding flexible blade guard.
Fig. 1. structural representation of the present utility model (open mode);
Fig. 2. the vertical view of Fig. 1;
Fig. 3. structural representation of the present utility model (closing up state);
Fig. 4. the rearview of Fig. 1 (partial view).
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Preceding flexible blade guard (7), work top (6), last connecting rod (9), the same with prior art.
The cross section of preceding flexible blade guard (7) is
Shape, front surface are circular arc, and the rear surface is the ladder plane, and in edge one through hole are arranged.
The cross section of back flexible blade guard (10) is
Shape has a through hole on the edge, rear surface.
Forward and backward flexible blade guard (7), (10) are utilized the through hole on it, earlier, after be enclosed within on the bearing saddle bore on the framework (1), and cover plate (8) is screwed on the end face of bearing saddle bore, make forward and backward flexible blade guard (7), (10) can not skid off.
To go up connecting rod (9), (12), one end of middle connecting rod (13) connects into rotating one with bearing pin, and end flexibly connects with forward and backward flexible blade guard (7), (10) and lower link (4) respectively in addition, and the end in addition of lower link (4) is movably connected on the rocking bar (2), and fulcrum (5) is arranged.
The place is movably connected on the framework (1), and fulcrum (11) is arranged in the middle of the middle connecting rod (13).
Framework (1) and rocking bar (2) are by axle (3), and connecting into to be the one that fulcrum rotates around axle (3) and with it.
When the pattern of cutting sth. askew is used, when the downward press box frame of operator (1), at this moment framework (1) rotates around axle (3) clockwise direction, lower link (4) also rotates around fulcrum (5) clockwise direction simultaneously, and connecting rod (13) and the connected connecting rod (9) of going up in driving, (12) rotate, thereby connected preceding flexible blade guard (7) is counterclockwise rotated, then flexible blade guard (10) clockwise direction rotates, before, back flexible blade guard (7), (10) just open automatically, and get out of the way workpiece, make the sawtooth (14) that exposes to carry out cutting operation, position as shown in Figure 1.
If the operator upwards lifts framework (1); then framework (1) counterclockwise rotates around axle (3); lower link (4) also counterclockwise rotates around fulcrum (5) simultaneously; connecting rod in the drive (13) and upward connecting rod (9), (12) rotation, and the rotation of preceding flexible blade guard (7) clockwise direction, then flexible blade guard (10) counterclockwise rotates; forward and backward flexible blade guard (7), (10) are closed up automatically; and leave workpiece, and the sawtooth that will expose (14) protects, as shown in Figure 3 the position.
The utility model compared with prior art, so double door protective device, simple in structure, only need former Front flexible blade guard place is arranged, connects again a rear flexible blade guard with upper connecting rod, and described upper connecting rod with Upper connecting rod connection before existing on the flexible blade guard forms. Forward and backward flexible blade guard is all concentrated on On the framework, take full advantage of top space, and remove on the work top, original operator's sight line of blocking Fixed blade guard makes the operating space become big, and overall structure, layout are more reasonable, so use, operation peace more Entirely, reliably.
Claims (3)
1. compound saw pattern double door protective device of cutting sth. askew, flexibly connect with last connecting rod (9) by the preceding flexible blade guard (7) that is installed on the framework (1), the in addition end of last connecting rod (9) is by being movably connected in the middle connecting rod (13) on the framework (1) and connecting to form with lower link (4) that rocking bar (2) flexibly connects, it is characterized in that: flexible blade guard (7) locates also to connect a back flexible blade guard (10) that has a connecting rod (12) before described, described last connecting rod (9) flexible connection of going up on connecting rod (12) and the preceding flexible blade guard (7).
2. protector according to claim 1 is characterized in that the cross section of back flexible blade guard (10) is
Shape has a through hole on the edge, rear surface, forward and backward flexible blade guard (7), (10) are utilized the through hole on it, earlier, after be enclosed within on the bearing saddle bore on the framework (1), and cover plate (8) is screwed on the end face of bearing saddle bore.
