Description

Rotary open type safety purse seine

Technical field

The utility model belongs to fence, relates in particular to a kind of rotary open type safety purse seine.

Background technology

When transformer station, petrol filling station and the construction of other hazardous area, carry out the place at any time and isolate, especially Gu Ding power transformation, chemical industry place, all will regularly clear up construction every year, all needs to isolate bigger scope when the time comes.In common construction, isolation rail is set is mostly with on-the-spot odds and ends to be that the supporter binding is provided with, but this mode is not suitable for the electric power place because the on-the-spot odds and ends of electric power facility all may be charged, so power department must be when fence being set with the scene in these places outside ad hoc vertical rod be supporter.

Summary of the invention

The purpose of this utility model provides a kind of rotary open type safety purse seine easy to use.

For achieving the above object, the utility model adopts following technical scheme: a kind of rotary open type safety purse seine, its center is a fixed axis, upper bearing (metal) is equipped with on top at fixed axis, lower bearing is equipped with in the bottom of fixed axis, upper bearing sleeve is housed on the upper bearing (metal), lower bearing sleeve is housed on the lower bearing, be set with rotating shaft on the fixed axis, the rotating shaft two ends link to each other with lower bearing sleeve with upper bearing sleeve respectively, safety net one end and rotating shaft are connected, safety net is coiled in the rotating shaft, there is the lower end of a sleeve to link to each other with upper bearing sleeve, sleeve middle part suit one positioning seat, on the positioning seat outer wall has, following two boss, inner rotary table is placed on the lower convex platform, and the inside door upper end is connected with inner rotary table, and inside door lower end and chassis are connected, the chassis is positioned at the lower bearing below, outer rotary table is placed on the convex platform, and the external door upper end is connected with outer rotary table, and locating ring is equipped with in the external door lower end, outer handle is arranged on the external door wall, the sleeve upper end links to each other with rotating disk, and handle is housed on the rotating disk, and loam cake is equipped with in the fixed axis upper end, on cover banking pin be housed, the pin-and-hole that matches with banking pin is arranged on the rotating disk.

The safety net other end has hook, and having on the outer rotary table can be for the hook hole of hook insertion.

Lower bearing joins with the step that is positioned at its below, and step and fixed axis are connected.

The chassis is enclosed within outside the step, and the locating ring and the chassis of external door lower end join.

The inside door edge is equipped with Internal handle.

Inside door is circular arc, and its radian is spent between 270 degree 180, and external door also is circular arc, and its radian is spent between 300 degree 180.

Adopt the safe purse seine of technique scheme, inside door and external door can be opened in any direction in 360 degree direction rotations, are contained in the safety net randomly receiving and releasing in the rotating shaft, can in very short time, the construction site be isolated with a plurality of safe purse seines, very easy to use.

The specific embodiment

Rotary open type safety purse seine as shown in Figure 1, its center is a fixed axis 1, on the top of fixed axis 1 upper bearing (metal) 19 is housed, lower bearing 3 is equipped with in the bottom of fixed axis, upper bearing sleeve 18 is housed on the upper bearing (metal) 19, lower bearing sleeve 4 is housed on the lower bearing 3, and lower bearing 3 joins with the step 2 that is positioned at its below, and step 2 is connected with fixed axis 1.Be set with rotating shaft 8 on the fixed axis 1, rotating shaft 8 two ends link to each other with lower bearing sleeve 4 with upper bearing sleeve 18 respectively, and safety net 5 one ends and rotating shaft 8 are connected, and safety net is coiled in the rotating shaft.There is the lower end of a sleeve 13 to link to each other with upper bearing sleeve 18, sleeve 13 middle part suits one positioning seat 17, the positioning seat outer wall has upper and lower two boss, inner rotary table 9 is placed on the lower convex platform, inside door 6 upper ends and inner rotary table 9 are connected, and inside door 6 lower ends and chassis 20 are connected, and chassis 20 is positioned at lower bearing 3 belows, outer rotary table 16 is placed on the convex platform, and having on the outer rotary table 16 can be for the hook hole 15 of hook insertion.External door 7 upper ends and outer rotary table 15 are connected, and locating ring 21 is equipped with in the external door lower end, and chassis 20 is enclosed within outside the step 2, and the locating ring 21 and the chassis 20 of external door lower end join.As shown in Figure 4, the safety net other end has hook 22, and outer handle 23 is arranged on the external door wall, and Internal handle 24 is arranged on the inside door wall.Sleeve 13 upper ends link to each other with rotating disk 10, and handle 14 is housed on the rotating disk 10, and loam cake 12 is equipped with in fixed axis 1 upper end, on cover banking pin 11 be housed, the pin-and-hole that matches with banking pin is arranged on the rotating disk 10.

Inside door is circular arc, and its radian is spent between 270 degree 180, and external door also is circular arc, and its radian is spent between 300 degree 180.The radian and the external door of inside door match, and can after safety net is rolled it be covered fully.

Because inner rotary table and outer rotary table are to be placed on the upper and lower boss of positioning seat, add the effect of chassis and locating ring, then inside door and external door can rotate in 360 degree directions around fixed axis, and can open in any direction.

As Fig. 2, Fig. 3, shown in Figure 4, handle is collapsible, can extract out in rotating disk 10 when needed, can roll well after using up again and get back into.

The utility model needs a plurality of safe purse seines to use simultaneously when construction, and the fixed axis lower end is fixed on the ground, pull handle, transhipment inside door, external door expose safety net, simultaneously, but extract the folding and unfolding handle out, rotating shaft, an end of pulling safety net hangs over the hook of safety net end in the hook hole on another safe purse seine outer rotary table, press banking pin it is entered in the pin-and-hole on the rotating disk, then rotating shaft can't be rotated.The same manner installs several safe purse seines in addition, then forms a construction site that requires the sealing of shape arbitrarily.

After construction finishes, will link up with from hook hole and take out, and pull up banking pin, turning handle is coiled in safety net in the rotating shaft again, and last pulling handle gets final product inside door, external door closure.
