Detailed Description

The following further description is made with reference to the embodiments shown in the drawings.

The elevator inspection safety warning device shown in fig. 1 comprises a device body 1, a guide plate 7, a limiting plate 8, a cross bar (not shown), a cross bar 3, a rotating rod 9, a motor 2, a support rod 4 and a sleeve 5. The device main body is provided with a groove; the left side and the right side of the inner wall of the groove are respectively provided with two guide grooves 6; the guide plate and the limiting plate are respectively positioned in the two guide grooves in a vertically sliding manner (the guide plate is arranged in the guide groove on the left side in the figure, and the limiting plate is arranged in the guide groove on the right side). One end of the cross rod is fixedly connected with the lower part of the guide plate, and the other end of the cross rod is fixedly connected with the lower part of the limiting plate, so that the guide plate and the limiting plate are connected into a whole.

As shown in fig. 2, the guide plate is provided with a hollow inside. The rotating rod is vertically arranged, wherein the lower part of the rotating rod extends into the guide plate, the upper end of the rotating rod extends upwards to the outside of the guide plate, and a positioning nut 10 is connected with the upper end of the rotating rod in a threaded manner; the rotating rod is rotatably connected with the guide plate through a bearing (not shown in the figure). A guide rod (not shown in the figure) for vertically guiding the positioning nut is fixed at the top of the guide plate so as to prevent the positioning nut from rotating along with the rotating rod; when the rotating rod rotates, the positioning nut moves vertically along the guide rod. The transverse bar is arranged above the transverse bar, and warning words can be pasted on the transverse bar so as to prompt people; one end of the transverse bar extends into the guide plate and is fixedly connected with the lower part of the rotating rod, and the transverse bar can be wound by rotating the rotating rod; the other end of the horizontal bar is fixedly connected with a mounting plate 11. The side surface of the limiting plate (namely the left side of the limiting plate) is provided with a mounting groove 12; the mounting plate is detachably positioned in the mounting groove through the positioning assembly.

When the warning board is used, the transverse bar is pulled out of the guide plate, the mounting plate is inserted into the mounting groove, the mounting plate is fixed through the positioning assembly, and then the transverse bar can be tensioned, so that the warning words on the transverse bar are unfolded to prompt people; after using the completion, take out the mounting panel from the mounting groove, later rotate the bull stick, twine the horizontal bar on the bull stick, realize that the rolling of horizontal bar is preserved, avoid the horizontal bar to suffer the damage. During the unfolding or rolling process of the transverse bar, the rotating rod synchronously rotates, so that the positioning nut is driven to vertically move; the rotating position and the rotating angle of the rotating rod can be limited according to the position of the positioning nut, and then the transverse bar is completely unfolded or rolled and stored. In this embodiment, when the positioning nut is attached to the top of the guide plate, the positioning nut cannot move downward continuously, and at this time, the horizontal bar is completely unfolded (see fig. 1); when the positioning nut moves to the top end of the rotating rod, the positioning nut cannot move upwards continuously, and the transverse strip is completely rolled up (not shown in the figure).

As shown in fig. 3 and 4, the positioning assembly includes a movable slot 15, a positioning rod 14, a guide block 16, a clamping edge 18 and a spring 17. The movable groove is formed in the top of the limiting plate; the positioning rod vertically penetrates through the movable groove and then extends into the mounting groove; the middle part of locating lever is encircled outward and is equipped with the round guide block, through guide block and activity tank bottom joint to avoid the locating lever to drop to the mounting groove in. The opening at the top of the movable groove is bent towards the inner side of the movable groove, so that a circle of clamping edge is formed; the spring is installed between guide block and card limit and the cover is established in the locating lever periphery, under the restriction effect on card limit, can prevent that the spring from popping out from the activity groove. And the mounting plate is provided with a positioning groove 13 which is in splicing fit with the bottom of the positioning rod.

When the fixing device is used, the positioning rod is pulled upwards, the spring between the clamping edge and the guide block is compressed under the stress, the mounting plate is inserted into the mounting groove at the moment, then the positioning rod is loosened, and under the action of gravity and the elastic force of the spring, the positioning rod is inserted into the positioning groove, so that the mounting plate can be fixed; on the contrary, when the horizontal bar needs to be rolled, the positioning rod is pulled upwards, the bottom of the positioning rod is separated from the positioning groove, the mounting plate can be taken out from the mounting groove, and the subsequent rolling operation of the horizontal bar is facilitated.

The motor is vertically fixed at the bottom of the groove; the support rod is fixed at the tail end of the motor shaft and driven by the motor; the sleeve is sleeved on the supporting rod in a threaded manner and is fixedly connected with the cross rod (namely, the sleeve is in threaded connection with the supporting rod, the supporting rod can also adopt a screw rod, and the sleeve adopts a nut). During the use, starter motor drives the bracing piece and rotates, because sleeve and horizontal pole fixed connection to the deflector and the limiting plate at horizontal pole both ends can't rotate under the effect of guide way, therefore the sleeve is along the vertical motion of bracing piece, and then drives deflector and limiting plate along vertical direction synchronous motion in the guide way through the horizontal pole, realizes the regulation of the vertical height of horizontal bar, and the crowd of adaptable co-altitude improves the suitability of device, and is nimble convenient.

Finally, it should be noted that the above-mentioned embodiments illustrate only specific embodiments of the invention. Obviously, the present invention is not limited to the above embodiments, and many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
