Description

The folding safety protector

The utility model is the improvement to safety device (as the door and window of operating a switch, roll-type window or door etc.).

Safety devices such as existing roll-type window or door, the door and window of operating a switch, the cost height, floor space is big, uses inconvenience, and roll-type window or door can only spur use up and down, and stuck phenomenon occurs easily.

The purpose of this utility model provides a kind of improved safety device, to reduce cost, reduces floor space, improves ease of use.

The utility model is achieved in that at the two ends of the non-sealing or the blade of operating a switch porose, and is installed in respectively on the diaxon by the hole, and the sleeve pipe of interval action has been arranged between two blades on the axle.On the closed blade of operating a switch, two ends become arcuation, and two blade pass are crossed the two ends intersection Colaesce of this one-tenth arcuation, and are free to rotate.What connect like this operates a switch blade installation in track, the other end of track or the two ends receipts box of operating a switch.In protector, synchronous parallel movement apparatus is housed with respect to the other end of receiving box of operating a switch.On protector, also roller can be installed.

Adopt the safety device of said structure, floor space is little, and folding is flexible, both can use up and down, also can about use, material usage reduces, and cost is low, can be as required, change track shape (as arc, trapezoidal etc.), applicability is strong, and is solid durable, safe and reliable, is difficult for taking place stuck phenomenon.

Describe structure of the present utility model below with reference to the accompanying drawings in detail.

Fig. 1 and Fig. 2 have represented a kind of structure chart of the non-enclosed blade of operating a switch in the utility model.Fig. 3, Fig. 4 have represented the subssembly drawing of non-enclosed protective device.Fig. 5, Fig. 6, Fig. 7 have represented the schematic diagram that non-enclosed protective device moves in the track and the receipts box of operating a switch.Fig. 8 has represented the non-close and protect schematic representation of apparatus after the assembling.Fig. 9 has represented a kind of structure chart of the closed blade of operating a switch.Figure 10, Figure 11, Figure 12 have represented the schematic diagram that closed protective device moves in the track and the receipts box of operating a switch.Figure 13 has represented the schematic diagram after closed protective device launches in track.Figure 14,15 has represented the schematic diagram that the closed blade of operating a switch connects.Figure 16 is that the vane stress end of operating a switch in the utility model is installed situation behind the roller.Figure 17,18,19 provides three kinds of tracks and has operated a switch and receive the shape of box.Figure 20,21 has represented the structure of the another kind of non-enclosed blade of operating a switch.Figure 22 is the schematic diagram of synchronous parallel movement apparatus in the utility model.

From accompanying drawing 1-8 as can be seen, the two ends of the non-enclosed blade 1 of operating a switch are porose 2 in the utility model, and the blade pass via hole is set on the axle 3, and the sleeve pipe 4 of interval action has been housed on the axle between two blades.The catch 8 and the latch 7 of fixation have been arranged outside the protector outermost sleeve pipe after assembling, and Figure 20,21 has represented the structure of the another kind of non-enclosed blade of operating a switch.Fig. 5,6,7 has represented the situation that the non-enclosed blade of operating a switch after the assembling moves in the track 6 and the receipts box 5 of operating a switch.Wherein Fig. 5 is the situation after blade is regained fully, and Fig. 6 is the situation of blade in moving process, and Fig. 7 is the situation after blade is fully withdrawn.Track 6 wherein can have arc, shape such as trapezoidal as required.The blade 1 of operating a switch shown in Figure 1 also can be adorned gauze, organic glass, plastic sheeting etc. as required.

As can be seen from Figure 9, the both ends 10 of the closed blade 9 of operating a switch are arcuation in the utility model.Shown in Figure 14,15, blade 9 gets up by the two ends intersection Colaesce of this one-tenth arcuation, and is free to rotate.Big and small blade is staggered to be installed, and it is fixing that latch 7 is inserted in the assembling back.In Figure 13, connecing lock vane stress position (lower end) has roller 11.Figure 16 is the concrete installation situation of roller.

As shown in figure 22, in the synchronous parallel movement apparatus of the utility model, the runner of four symmetrical distributions (or sprocket wheel) 13,14,15,16 is installed on the assembly 12 of operating a switch by axle 17,18,19,20 respectively, and the assembly of operating a switch is positioned at the other end with respect to the receipts box 5 of operating a switch.The assembly 12 of operating a switch is the structure that forms between the outermost diaxon 3 in non-enclosed protective device, is blade of outermost in closed protective device.Rope (or chain) 2 is walked around runner (or sprocket wheel) 13,15, and rope (or sprocket wheel) 22 is walked around two ends, 14,16 back and fixed, and track was received in the box with operating a switch about rope (or sprocket wheel) was installed in.Because two ropes (or chain) equal in length, and the power equal and opposite in direction, the direction that act on the assembly 12 of operating a switch are opposite, therefore can guarantee protector when drawing back or regain, and synchronously parallel moving prevented the generation of stuck phenomenon.
