Abstract
A self-locking mechanism for a non-maintained door leaf relates to a self-locking mechanism to solve problems of complicated operation and time- and labor-consumption due to that conventional non-maintained door leaves are locked by door fasteners and closed manually. The self-locking mechanism consists of a latch bolt, a connecting plate, a positioning plate, a spring, a case and a pull rod; one end of the case is open; the open end of the case is detachably connected with the connecting plate; the positioning plate is mounted in the case and two ends of the positioning plate are fixedly connected with the case; a first through hole is reserved in the connecting plate; a second through hole is reserved in the positioning plate; the first and second through holes are coaxially disposed; the latch bolt goes through the first and second through holes and is slidingly connected with the positioning plate; one end of the pull rod is mounted in the case and rotatably connected with the latch bolt; and the spring is mounted on the pull rod and positioned between the latch bolt and the other end of the case. The self-locking mechanism is used for automatically locking non-maintained door leaves of a plurality of burglarproof doors.
Description
Technical field
The utility model relates to a kind of self-locking mechanism.
Background technology
The non-hold-open door fan pass of existing security door often adopts the door latch type locking, realizes the switch of non-hold-open door fan by the manual operation of bolt, troublesome poeration, and waste time and energy.
The utility model content
The purpose of this utility model provides a kind of self-locking mechanism that is used for non-hold-open door fan, often adopts the door latch type locking to solve present non-hold-open door fan pass, closes troublesome poeration, and the problem that wastes time and energy by what the non-hold-open door of manual realization was fanned.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: described self-locking mechanism is by oblique tongue, junction plate, location-plate, spring, housing and pull bar constitute, one end of described housing is uncovered, and the opening end and the junction plate of housing removably connect, it is affixed that described location-plate is contained in housing two ends and housing interior and location-plate, described junction plate is provided with first through hole, described location-plate is provided with second through hole, first through hole and the coaxial setting of second through hole, described oblique tongue passes first through hole and second through hole and location-plate and is slidingly connected, one end of described pull bar is contained in the housing and spins with oblique tongue, and described spring is contained on the pull bar and between the other end inwall of tiltedly tongue and housing.
The utlity model has following beneficial effect: the utility model has realized that closing the door of non-hold-open door fan and locking action finish in the lump, has avoided loaded down with trivial details, the problem that wastes time and energy of manual operation process.The non-hold-open door fan of the utility model is closed flexibly, good stability, and unlatching and lock operation are convenient, with low cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1 and Fig. 2, the self-locking mechanism of present embodiment is by oblique tongue 1, junction plate 2, location-plate 3, spring 4, housing 5 and pull bar 6 constitute, one end of described housing 5 is uncovered, and the opening end of housing 5 and junction plate 2 removably connect, it is affixed that described location-plate 3 is contained in housing 5 two ends and housings 5 interior and location-plate 3, described junction plate 2 is provided with the first through hole 2-1, described location-plate 3 is provided with the second through hole 3-1, the first through hole 2-1 and the coaxial setting of the second through hole 3-1, described oblique tongue 1 passes the first through hole 2-1 and the second through hole 3-1 and location-plate 3 and is slidingly connected, one end of described pull bar 6 is contained in the housing 5 and with oblique tongue 1 and spins (employing thread connecting mode), and described spring 4 is contained on the pull bar 6 and between the other end inwall of tiltedly tongue 1 and housing 5.
The specific embodiment two: in conjunction with Fig. 2 present embodiment is described, the described oblique tongue 1 of present embodiment, housing 5 and pull bar 6 coaxial settings, accurate positioning when this structure can guarantee the utility model installation.Other composition and annexation are identical with the specific embodiment one.
Operating principle: the utility model be installed in top, the below in the security door or be installed in simultaneously above or below, guarantee that oblique tongue 1 contacts with upper door frame or lower door frame, pull bar 6 is connected with door lock, when opening door lock, drives pull bar 6 motions, the oblique tongue 1 of pull bar 6 pullings slides, with spring 4 compression, when reach requirement that door leaf cuts out apart from the time, tiltedly tongue 1 is under the effect of spring 4 elastic force, be inserted in the preformed hole of doorframe, to reach the effect of locking door leaf.
