Description

The rolling door theftproof lock

Technical field

The utility model belongs to lockset, makes the field especially for the lockset of rolling door.

Background technology

At present, generally the Rolling Door Lock of Shi Yonging is made up of locking bolt (round steel) and lock tube (circle fixes on the ground, has the collar of lockhole).During switch lock, make the lock core rotation,, the locking bolt occurred level is moved, extract out or insert in the hole of lock tube by a leverage with key.Be characterized in, be fixed on lock tube on the ground, protrude all the time on ground, become a roadblock, especially after rolling door is opened,, make troubles and inconvenient the pedestrian who passes in and out in the built-in fitting mode.

The utility model content

Task of the present utility model is to provide a kind of rolling door theftproof lock, and its lock tube can not form roadblock after rolling door is opened.This task is realized by following design: a kind of rolling door theftproof lock, occurred level moves when comprising with lock core interlock, switch lock locking bolt and lock tube, it is characterized in that, also comprise the lock frame: constitute with the identical pipe nipple sleeve pipe of two internal diameters that connects firmly on this base plate by base plate, have a hole on this base plate, this two pipe nipples sleeve pipe is along same axis direction setting, and the center of circle of hole is positioned on this axis; Described locking bolt is made of lock and the force rod that is welded on the about medium position of lock; Two pipe nipple sleeve pipe snares are on lock; Described force rod at the back point on the lock to the distance of lock front end face greater than the distance between the two pipe nipple sleeve pipes less than the distance of pipe nipple sleeve pipe front end face to pipe nipple sleeve pipe front end; Described lock tube is made of the cylindrical pullover and pile body that mutual spiral connects, and this pullover diameter is slightly less than hole diameter, has the lockhole of a diameter greater than the lock diameter on pullover.More than in the design, lock tube adopts the two parts that connected by spiral to form, and constitutes detachable structure.After rolling door is opened, can take off easily and connects, protrude on the ground pullover with pile body, because the pile body of lock tube is pre-buried underground and can keep flushing with ground, thereby, the novel disadvantage that has the lock tube roadblock after the existing rolling door unlatching of having eliminated.This is novel to have characteristics simple in structure, easy to use.

The specific embodiment

Fig. 1 Fig. 2 Fig. 3 illustrates, and locking bolt is made up of lock 3 and force rod 3a, and lock 3 adopts round steel, and force rod 3a is welded on the about medium position of lock, has eyelet 3b on the force rod, is used to connect the leverage that links with lock core.Referring to Fig. 4, lock frame 4 is made up of base plate two pipe nipple sleeve pipe 4a, the 4b identical with internal diameter, has a hole 4c on the base plate, and two pipe nipple sleeve pipe 4a, 4b are welded on the base plate along same axis direction, and the center of circle of hole 4c is positioned on this axis.Lock tube is made of cylindrical pullover 2 and the pile body 1 that mutual spiral connects, and pullover 2 diameter (external diameter) is slightly less than hole 4c diameter, has lockhole 2a on pullover, and its diameter is greater than the diameter of lock 3.Lock 3 is inserted among two pipe nipple sleeve pipe 4a, the 4b, force rod 3a less than the distance of pipe nipple sleeve pipe 4b front end face to pipe nipple sleeve pipe 4a front end face, can break away from the effect that can not deviate from again greater than the distance between the two pipe nipple sleeve pipes (i.e. distance between the two sleeve pipe adjacent both ends faces) to the distance of lock front end face at the back point on the lock (before and after so-called with respect among Fig. 1 about figure for) from pipe nipple sleeve pipe 4a from the tapered end of lock tube when being moved horizontally to right stop to play locking bolt.Among Fig. 1, pullover 2 bottoms of lock tube are screw rod; Pile body 1 is the inboard sleeve pipe that has the silk mouth.Also pullover bottom can be designed to the sleeve pipe of silk mouthful, and pile body is designed to screw rod and cooperatively interacts.During installation, the base plate of locking frame is connected firmly on the rolling door bottom girder by bolt or welding, the pile body 1 of lock tube is embedded in the ground, and its upper surface flushes with ground.Last locking bit for convenience of locking bolt, be among the lockhole 2a of lock 3 accurate insertions pullover 2, referring to Fig. 4, make the part of the hole 4c on lock frame 4 base plates topped by pipe nipple sleeve pipe 4a institute less than semicircle, along its axis direction excision part, make its shape of cross section and hole 4c except by the shape behind the covered portion similar (being the pullover embodiment shown in Fig. 1 Fig. 2) pullover 2 upper cylinder.In the use, when closing rolling door, be screwed on the pile body 1 pullover 2, the rolling door of leaving behind with key turn lock core, drives locking bolt and is moved to the left, and lock 3 inserts to finish among pullover 2 the lockhole 2a and locks; When opening rolling door,, drive locking bolt and be moved to the left with key turn lock core, lock 3 is deviate from from pullover 2 lockhole 2a, finish and unblank, take off pulloverly 2 after unblanking, cover plate shown in Figure 55 is screwed on the pile body 1 (can offer on the projection of cover plate 5 silk mouthful).
