Abstract

An antitheft cat eye comprises an inner casing and an outer casing which are connected through an inner thread and an outer thread. The inner wall and the outer wall of each of the inner casing and the outer casing are respectively provided with a plurality of inner longitudinal grooves and a plurality of outer longitudinal grooves. Among all the inner and outer longitudinal grooves, openings of at least one pair of the inner and outer longitudinal grooves align to each other and are inserted with a locking bar, and therefore, when the inner and outer casings are respectively inserted into a prepared hole of the cat eye from the interior and the exterior of a door and are connected and screwed almost tightly through the inner and outer threads, the openings of one of pairs of the inner and outer longitudinal grooves align to each other, and the locking bar is inserted into the inner and outer longitudinal grooves from the door to have the inner and outer casings locked tightly; in this case, thefts cannot unscrew and remove the outer casing by rotating the outer casing from outside the door and cannot insert an unlocking tool into the prepared hole of the cat eye from outside the door to open the door for stealing, so that antitheft performance of the cat eye is greatly improved; therefore, the antitheft cat eye is more reasonable in structure and higher in antitheft performance.

Description

Burglarproof peep hole

[technical field]

The utility model relates to a kind of opal (being again door scope) being arranged on door.

[background technology]

We know, the current burglarproof peep hole being installed on door, substantially be that inside and outside sleeve pipe with " protruding " font, mesopore is threaded connection respectively and is clamped in door and installs from the inside and outside insertion opal of door preformed hole, in the hole of outer tube, be provided with optical lens or electronic camera system to observe situation outdoors.This opal, because undesirable just can disassemble outer tube make outdoors inside and outside sleeve pipe separately by rotary sleeve pipe after, then from opal preformed hole, stretching into unlocking tool opens door and steals, thereby leave potential safety hazard to security door, therefore this current class opal need to improve, and this is the applicant's purpose just.

Prior art is compared, the beneficial effects of the utility model are: due to interior, in outer tube, on outer wall, be respectively equipped with in some, outer wall longitudinal fluting, when tight condition, have at least a pair of in, the opening of outer wall longitudinal fluting aligns, like this, when interior, outer tube is respectively in door, outer reeve opal preformed hole and pass through in, external screw thread connects to be screwed to while almost tightening to be made in a couple wherein, the opening of outer wall longitudinal fluting aligns, then locking rod is internal from being inserted into this in door, in outer wall longitudinal fluting, be lockable in, outer tube, in this case, undesirable just cannot back-out by rotary sleeve pipe from door, lay down outer tube, thereby cannot open door and steal from outdoors unlocking tool being stretched into opal preformed hole, also just greatly improved the theftproof of opal, so more reasonable structure of the present utility model, theftproof performance is higher.

Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:

[utility model content]

The purpose of this utility model is to be to overcome the deficiencies in the prior art, a kind of more reasonable structure is provided, can have improved the burglarproof peep hole of theftproof performance.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:

A burglarproof peep hole, includes the inside and outside sleeve pipe linking together by internal and external screw thread, is respectively equipped with some inside and outside wall longitudinal flutings on the inside and outside wall of described inside and outside sleeve pipe; In all inside and outside wall longitudinal flutings, have at least the opening of a pair of inside and outside wall longitudinal fluting to align and be inserted with locking rod.

In to the improvement project of above-mentioned burglarproof peep hole, at described locking rod tail end, be provided with collar, at the inwall tail end of described inner sleeve, be provided with for holding the draw-in groove that holds of collar.

In to the improvement project of above-mentioned burglarproof peep hole, the inwall longitudinal fluting in described inner sleeve pore has one, and the outer wall longitudinal fluting of outer tube has six at least.

[accompanying drawing explanation]

Fig. 1 is the schematic perspective view of the utility model embodiment;

Fig. 2 is the assembling schematic diagram of the utility model embodiment;

Fig. 3 is the structural representation of the utility model embodiment;

Fig. 4 is the enlarged drawing of the local I of Fig. 3.

[specific embodiment]

The utility model is a kind of burglarproof peep hole, as shown in Figures 1 to 4, include the inside and outside sleeve pipe 1,2 linking together by internal and external screw thread, in the hole of this outer tube 2, be provided with optical lens or electronic camera system, on the inside and outside wall of described inside and outside sleeve pipe 1,2, be respectively equipped with some inside and outside wall longitudinal flutings 11,21, in all, outer wall longitudinal fluting 11, in 21, have at least in one pair, outer wall longitudinal fluting 11, 21 opening aligns and is inserted with locking rod 3, like this, when interior, outer tube 1, 2 respectively in door, outer reeve opal preformed hole and pass through in, external screw thread connects to be screwed to while almost tightening to be made in a couple wherein, outer wall longitudinal fluting 11, 21 opening aligns, then locking rod 3 is internal from being inserted into this in door, in outer wall longitudinal fluting, be lockable in, outer tube 1, relatively rotating between 2, in this case, undesirable just cannot back-out by rotary sleeve pipe 2 from door, lay down outer tube, thereby cannot open door and steal from outdoors unlocking tool being stretched into opal preformed hole, also just greatly improved the theftproof of opal, so more reasonable structure of the present utility model, theftproof performance is higher.

Preferably, in the present embodiment, described locking rod 3 is generally steel wire, at its tail end (i.e. that one end contrary with its insertion end), be provided with the collar 31 of arc, at the inwall tail end of described inner sleeve 1, be provided with and hold draw-in groove 12 for what hold collar 31, in locking rod is inserted into, in a couple between outer tube, outer wall longitudinal fluting 11, in the time of in 21, what collar 31 was compressed into inner sleeve holds draw-in groove 12, so both facilitate staff to grab and on collar, inserted or taken out locking rod, people in again can overslaugh room sees through opal and observes situation outdoors, all right further fixedly locked rod, prevent from dropping out.

The present embodiment is as preferred embodiment, inwall longitudinal fluting 11 in inner sleeve 1 hole has one, and the outer wall longitudinal fluting 21 of outer tube 2 has six (being advisable with 8 to 10) at least, by outer wall longitudinal fluting 21, distribute closelyer like this, just can when making inside and outside sleeve pipe 1,2 clamp door, more easily make this inwall longitudinal fluting 11 aim at that the most contiguous outer wall longitudinal fluting 21.When opening a plurality of inwall longitudinal fluting 11 in inner sleeve 1 hole, be unfavorable on the contrary inserting locking rod, because inside and outside longitudinal fluting itself is just very tiny, because inside and outside longitudinal fluting is when all many, in the time of at this moment will finding relative that of opening to inside and outside longitudinal fluting, easily see dazzledly.

Be only the utility model preferred embodiment in sum, be not used for limiting practical range of the present utility model, i.e. all equivalences of doing according to the content of the utility model claim change and modify, and all should belong to technology category of the present utility model.
