Description

A kind of type simple door lock structure

Technical field

The utility model relates to a kind of type simple door lock structures, belong to safety protection field.

Background technique

At some gates often entered and left, the gate knot used such as factories and miness gate, freight transport center gate or livestock-raising In structure, due to being frequently necessary to enter and leave, but be unable to being kept open for duration again, by it is general lock lock after, it is regular Switch lock it is cumbersome, need a kind of simple lock construction easy to use, without key, can either lock a door, also can be easily It opens.

Summary of the invention

The purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of type simple door lock structure, including peace Lock frame on the outside of doorframe, is mounted on the locking bar opening handle on the inside of doorframe and being fixedly mounted on door, the lock at lock ring The eccentric part of ring is hinged on the lock frame by hinge post, and the hinge post is greater than the lock ring with the lock frame at a distance from nearly door end Diameter, the hinge post is less than the radius of the lock ring at a distance from the lock frame far away from home end and is greater than on the outside of hinge post and lock ring Minimum range, in the case where the lock ring naturally droops state, the lower end of the lock frame is located above the lock ring center of circle, the locking bar The center of circle and the lock ring the center of circle it is contour, it is described in open handle be lever construction, one end of the lever construction passes through traction Rope is handle end around the nearly door side for connecting the lock ring after pulley, the other end of the lever construction.

The lock ring is forced always to be turned round to nature it is furthermore preferred that installing the first torsional spring between the hinge post and the lock ring Position when hanging down.

Force the handle end of the lever construction total it is furthermore preferred that the articulated position of the lever construction installs the second torsional spring It is far from doorframe.

The utility model has substantive features and progress compared with the prior art, and specifically, the utility model passes through lock The design of structure, the eccentric part of lock ring be hinged on lock frame on, and hinge post be located proximate to lock frame distal end so that lock ring be merely able to from Inside is flipped up, and can be blocked by the distal end of lock frame when from outer side to overturn, using the principle, so that locking bar is at closing time by lock ring It since lock ring can not rotate backward the locking that is stuck when jacking up, and opening the door, realizes and closes the door, opened from outside, it only need to be by lock ring top It rises, turns an angle from inside, opened from inside, then need lock ring pull-up by interior handle of opening, it is very convenient.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of type simple door lock structure in the utility model.

Fig. 2 is the structural schematic diagram locked at frame, lock ring and locking bar in the utility model.

Specific embodiment

Below by specific embodiment, the technical solution of the utility model is described in further detail.

As depicted in figs. 1 and 2, a kind of type simple door lock structure, lock frame 2, lock ring 3, installation including being mounted on 1 outside of doorframe The locking bar 6 opening handle 4 in 1 inside of doorframe and being mounted on door 5, the eccentric part of the lock ring 3 are hinged on institute by hinge post 7 State lock frame 1 on, the hinge post 7 and it is described lock 1 close end of frame at a distance from greater than the lock ring 3 diameter, enable lock ring 3 from Nearly door side is flipped up, and the hinge post 7 is less than the radius of the lock ring 3 at a distance from the lock 2 far away from home end of frame and is greater than hinge The minimum range in 3 outside of column 7 and lock ring, first is that stopping lock ring 3 to be flipped up from far away from home side, second is that retaining lock ring 3 from nearly door When side is flipped up, lock frame 2 will not to caused at its minimum range stop lead to not overturn, under 3 nature of lock ring Under the state of hanging down, the lower end of the lock frame 1 is located above 3 center of circle of lock ring, the circle in the center of circle of the locking bar 6 and the lock ring 3 The heart is contour, forms locking structure, the interior handle 4 of opening is lever construction, and one end of the lever construction is bypassed by traction rope 8 The nearly door side of the lock ring 3 is connected after pulley 9, the other end of the lever construction is handle end 10.

Working principle: door 5 be it is mobile, what doorframe 1 was usually fixed, when door 5 is closed to doorframe 1, locking bar 6 oppresses lock ring 3 It inwards rotates, lock ring 3 is jacked up, and after locking bar 6 enters on the inside of lock ring, lock ring 3 is naturally drooped, and forms locking structure, locking bar 6 is certainly When moving from inside to outside, 3 can be stapled and blocked, because lock ring can not rotate backward, when needing to open the door, peripheral operation is to be jacked up with hand Lock ring 3 rotates lock ring 3 from inside, and locking bar loses blocking, then pulls the door open, and is to push handle end 10 from internal operation, Under leverage, traction rope 8 is pulled, and lock ring is pulled up, and is turned to the inside, and locking bar loses blocking, is then pushed the door open.

In order to facilitate the reset of lock ring 3, the first torsional spring is installed between the hinge post and the lock ring and forces the lock ring total It is the position turned round to when naturally drooping.

The interior reset for opening handle 4 for convenience, the articulated position of the lever construction install the second torsional spring and force the thick stick The handle end of rod structure is always far from doorframe.

The preferred embodiment of the patent is described in detail above, but this patent is not limited to above-mentioned embodiment party Formula within the knowledge of one of ordinary skill in the art can also be under the premise of not departing from this patent objective It makes a variety of changes.
