The cylindrical portion of key locked in cylindrical portion is inserted in, the square groove coordinated with the fang platform, institute are provided with the cylindrical portion of key
Square groove is stated to can be inserted into the fang platform.
The opening for preventing tie down screw from coming off is provided with by the cotter-pin hold radially opened up on the tie down screw
Pin.
The utility model L-type anti-creep locking device, due to the cylindrical portion of tie down screw rearward end locking, shield,
General tool can not be stretched into the cylindrical portion of locking to be coordinated with fang platform, end fang platform category special construction, it is necessary to matched to have spy
The L-type key of different structure coordinates, and could open anti-creep door, realize the effect of antitheft anti-creep；
In addition, climbing a setting many places cotter-pin hold according to difference is counter in the middle part of tie down screw, the anti-of various gaps is applicable to
Door is climbed, split pin can prevent screw rod from coming off, and high-altitude is counter, and to climb anti-dropout essential；
Furthermore tie down screw leading section chamfering can make screw rod it is very well pass through the anti-hole climbed on door so that this fill
Put use it is more convenient.
The present apparatus may be not only suitable for steel tower anti-creep device, and other industry is also generally applicable, as big machinery critical piece can
Set up this device, the hatch door everywhere on steamer can set up this device etc..

Fig. 8 is that L-type anti-creep locking device is arranged on the anti-schematic diagram for climbing door.
Embodiment
Below, substantive distinguishing features of the present utility model and advantage are further described with reference to example, but this practicality is new
Type is not limited to listed embodiment.
Referring to shown in Fig. 1,8, a kind of steel tower prevents the L-shaped anti-creep locking device 100 of climbing, including for through anti-creep door
Tie down screw 1, the nut 2 being welded on anti-creep door and pad 3 for being threadedly coupled with the tie down screw, the lock
Tight end has the cylindrical portion 4 that locks, and has the fang platform 5 with tie down screw one, L-shaped anti-creep locking in the cylindrical portion of locking
For device 100 equipped with L-type key 9, the L-type key has the cylindrical portion 10 of key that can be inserted in the cylindrical portion of locking, institute
The square groove 91 for being provided with the cylindrical portion of key and coordinating with the fang platform is stated, the square groove can be inserted into the fang platform.
The L-shaped anti-creep locking device 100 is two the first door frames of door frame 7, second through anti-creep door when mounted
Frame 8 is installed, and the cylindrical portion 4 of locking is spacing by the second door frame 8, and nut 2 and pad 3 are integrally fixed at described first
On frame 7, there is gap after being installed between the middle part of tie down screw, i.e. two door frames, as shown in Figure 1 installation.First door frame 7, second
Door frame 8 is connected by hinge or hinge means with door pillar 13 respectively, and the door pillar 13 and L-shaped supporting plate 15 are by bearing pin 14
It is flexibly connected, on steel tower, realizes the function of preventing climbing.
Further, hole 110 is filled by the split pin radially opened up on the tie down screw and split pin 6 is installed, it is described
Split pin is located between lock washer and the cylindrical portion of locking.
The split pin can be one, or two, even more than, it is specific unlimited, it is located at the centre of the tie down screw
Position, it is applicable to the counter of various gaps and climbs door, split pin can prevents screw rod from coming off, and high-altitude is counter, and to climb anti-dropout essential.
The tie down screw front end 11 has chamfer 5X5.
The utility model can be opened or closed anti-creep locking device by L-type key；And with antitheft, anti-creep, anti-spiral shell
The bar effect of coming off etc., use is more convenient, and device for opening has selectivity；The device of this type can use different specifications and set
