Abstract
The present invention relates to an automatic locking device for a protective cover of the cutting table surface of a composite saw table. In the operating process of the conversion of working modes, a protective cover can be automatically locked and released in order to prevent saw teeth from touching hands, and thus, a protecting function is obtained. The protective cover is arranged on the cutting table surface. A cover cap of the protective cover is connected with a hanging rod. A cover hook with a spring is connected with a support bracket fixed on a frame. The other end of the spring is respectively fixed on the frame and an upper connecting rod connected with a movable protective cover. The upper connecting rod is formed by the way that a middle connecting rod is connected with a lower connecting rod fixed on a rocking rod. The operation and the use are convenient. Meanwhile, the cover hook is also provided with a stopping block which is buckled in the gap of a right protecting board for linkage and automatic lock. The present invention is safe and reliable to use.
Description
Technical field
The present invention relates to a kind of portable electric power tool, the major part protective cover of compound saw, in the working mode change operating process, this protective cover can automatically lock and decontrol, thereby prevent that sawtooth from touching staff, play the automatic locking apparatus of the guard hood for bench of combined saw of protective action.
Background technology
When compound saw is operated in when cutting sth. askew pattern, how the sawtooth that platform is cut on the table top realizes automatic protection, is a unsolved difficult problem always.Just adopted the way that work top is raise in the past, table top was raised up to sawtooth is all hidden under the table top, finger is touched less than being safety.
Such means of defence, for the table top of vertical lift, operation is very inconvenient, whenever carry out the conversion of one action pattern, just need table top to be raise or put down once, so frequent operation, if because of carelessness maloperation will take place, therefore exist a lot of unsafe hidden danger.
Summary of the invention
Purpose of the present invention: be to provide a kind of compound buck to cut the automatic locking apparatus of table top protective cover, protective cover is along with the conversion of operational mode state, and can automatically lock synchronously and decontrol, uses, easy to operate, and safety, reliable.
The present invention is achieved in that the automatic locking apparatus of guard hood for bench of combined saw, protective cover is installed in platform and cuts on the table top, be connected with peg on the cover cap in the described protective cover, having the cover hook of spring is connected with support on being fixed on framework, and the in addition end of spring be separately fixed on the framework with the last connecting rod that is connected with flexible blade guard on, last connecting rod by middle connecting rod be connected with lower link on being fixed on rocking bar form.
The present invention compared with prior art, the automatic locking apparatus of this protective cover is simple in structure, is made up of the cover cap of band peg and the cover hook that has extension spring, a support.In the transfer process of mode of operation, the cover hook can break away from the peg in the cover cap automatically and decontrol, can hook the peg in the cover cap automatically again and automatically lock, operation, easy to use, cover simultaneously on the hook and to also have scotch, in the transfer process of mode of operation, can also be buckled in the breach on the right protective plate, link, self-locking, use safer, reliable.
Description of drawings

Fig. 2. structural representation of the present invention (platform is cut state).
Fig. 3. the vertical view of Fig. 1 (taking away protective cover).
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described:
Cover cap 11 has the elongated cavity of opening for upper and lower two surfaces, and has one laterally to support shelves in the middle of upper surface.
Protective cover is by on the gusset of housing 11 front ends two walls, is fixed with circular peg 1, use bearing pin on the gusset of middle two walls, and is that fulcrum is connected with dwang 5 formations with it.
Protective cover is installed in platform and cuts on the table top 9, and an end of dwang 5 is movably connected in the upper end with knife plate 10, is screwed on framework 19 with knife plate 10 lower ends, constitutes the closing device of protective cover.
One end of extension spring 6,20 is fixed on the cover hook 2, and end is separately fixed on connecting rod 8 and the framework 19 in addition.
One end of last connecting rod 8 is movably connected on the flexible blade guard 14 with bearing pin, and end is connected with fulcrum middle connecting rod 13 on framework 19 and that link to each other with lower link 12 in addition, and the end in addition of lower link 12 is fixed on the rocking bar of compound saw.
Dead man handle 16 fuses with fork 17, two openends of fork 17 flexibly connect with left and right protective plate 15,21 respectively, and left and right connecting rod 23,4 flexibly connects with left and right protective plate 15,21, dead man handle 16 is fixed on the framework cover cap 18, left connecting rod 23 be connected on framework cover cap 18 sidewalls with right connecting rod 4 corresponding positions on.
During use, if when compound saw will convert platform to and cuts pattern, to pressing down, by fork 17 connected left and right protective plate 15,21 is put down on dead man handle 16, go to protect the table top declivity and cut the sawtooth 7 that exposes on the working face, press down fuselage this moment, and locking.
Meanwhile, flexible blade guard 14 is opened, coupled last connecting rod 8 is drawn back, extension spring on the cover hook 26 is stretched, because extension spring 6 is different with the arm of force of extension spring 20, make cover hook 2 do counterclockwise to rotate along the fulcrum on the cover hook support 22, automatically break away from the peg 1 on the cover cap 11, all entering platform up to cover hook 2 cuts in the saw kerf under the table top 9, do not exceed till the work top 9, break away from cover cap 11 fully, the automatic locking apparatus that this moment, platform was cut the table top protective cover is decontroled, and the closing device of protective cover can be along following knife plate 10 free closure or openness, as shown in Figure 2.
On the contrary, if convert the pattern of cutting sth. askew to from the platform pattern of cutting, at this moment fuselage is lifted, meanwhile, flexible blade guard 14 closes up downwards automatically, and rotation removes to protect the sawtooth 7 of bottom, and coupled last connecting rod 8 is to reach, loosen extension spring 6, cover hook 2 is done the clockwise direction rotation at the fulcrum on support 22 under the effect of extension spring 20, hook peg (1) on the cover cap (11) up to putting into gear on it, the cover cap 11 that platform is cut on the table top 9 pins, and then dead man handle 16 is upwards carried, make a connected left side by fork 17, right protective plate 15,21 pack up, and make breach on the right protective plate 21 withstand scotch 3 on the cover hook 2, and making that cover hook 2 is fixing can not to be moved, it is locked that this moment, platform was cut the automatic locking apparatus of table top protective cover.Working mode change finishes, and protection puts in place fully, as shown in Figure 1.
