According to the arc type nail-free anti-theft door back locking device, decomposition of force is utilized, the locking arm is arranged to be in a bent shape, the hinged manner is adopted, and the door pushing axial force is decomposed into radial force beneficially so that the effect that the larger the door pushing force is, the larger the locking force is can be achieved; and the arc type nail-free anti-theft door back locking device is convenient and easy to use and does not need drilling during installation.
Description
Technical field
Invention belongs to door closer engineering device technique field and in particular to a kind of circular arc type exempts to follow closely antitheft door closer.
Background technology
Existing frequently-used room door-locking mechanism has mechanical lock and electronic lock, and electronic lock is generally used in the door of hotel, comprising:
Electronic induction lock, fingerprint induction lock, acoustic control induction lock etc., but the electronic product of these new and high technologies lock equally exists shortcoming,
The electronic magnetic card opening the door easily is replicated, and fingerprint is easily replicated, and sound is easily replicated, and these door locks use in reality
In, happen occasionally to be cracked by stranger and open, burglary insurance coefficient is not high.At present people are in the Inner door lock of private residence is implemented, often
Use is mechanical lock, and mechanical lock is typically mounted on door and wall, reaches, by latch or linked set, the effect locked, but
It is that in reality, many anti-lock devices are relatively backward, can break disconnected easily because of long-term stress, stranger is easily accessible in room.For
The complex place of this environment in hotel and hotel, some are not provided with inside door anti-lock device, and guest is placed on the property in room
Safety is difficult to ensure, safety effect is not very satisfied.The apartment with hotel-styled services also having, because door is not allow to hole, for a long time
The guest staying in the inside can not install mechanical lock in door and wall privately, and manager still has standby key, exists certain
Potential safety hazard.
Content of the invention
For above-mentioned deficiency, the invention provides a kind of circular arc type exempts to follow closely antitheft door closer, the circular arc of the present invention
It is very easy to use that formula exempts to follow closely antitheft door closer, can carry with and lock effect it is not necessary to holing and just can reaching, lock performance
By force, by force mode open extremely difficult.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of circular arc type exempt to follow closely antitheft door closer it is characterised in that: include baffle plate, hammerlock, base, connecting bolt, described baffle plate
One side contact with the shop front, it is hinged with hammerlock that bearing pin is passed through in another mirror image face, described baffle plate and hammerlock hinged place be provided with for
Limit the opening of the hinged range of activity of hammerlock, the movable end of described hammerlock is provided with screw thread mouth, described connecting bolt afterbody and spiral shell
Stricture of vagina mouth connects, and the head of connecting bolt is connected in base, is provided with rotary knob between described hammerlock and base, described rotation
Knob is screwed in connecting bolt, and described rotary knob is contacted with ground by rotary squeezing base.
Specifically, described baffle bottom is provided with the supporting plate matching with door bottom, and described supporting plate and baffle plate are mutually perpendicular to.
Specifically, described baffle plate and supporting plate are provided with cushion pad with door touching position.
Specifically, described hammerlock is in arc-shaped, and the circular arc bearing of trend of described hammerlock movable end points to ground.
Specifically, it is provided with knob in the middle part of described hammerlock.
Specifically, described base is provided with plastic anti-skid pad.
In sum, the present invention is due to employing such scheme, the invention has the advantages that
(1) present invention is provided with rotary knob using between described hammerlock and base, and described rotary knob is screwed in connecting bolt
In, the form that described rotary knob is contacted with ground by rotary squeezing base, opposite house and ground applying radial force, reach locking
The effect of door, convenient and simple, installation of need not holing.
(2) present invention utilizes force resolution, and hammerlock is arranged to arc-shaped, by way of hinged, is conducive to pushing
Axial force is decomposed into radial force, reaches and more firmly pushes, the bigger effect of coupling mechanism force.
Brief description
Fig. 1 is that a kind of circular arc type of the embodiment of the present invention 1 exempts to follow closely antitheft door closer structural representation.
In figure part name and sequence number:
Baffle plate 1, supporting plate 101, opening 102, hammerlock 2, knob 201, connecting bolt 3, base 4, plastic anti-skid pad 5, rotation
Knob 6, bearing pin 7, cushion pad 8, door 9, ground 10.
Specific embodiment
With reference to embodiment, to the present invention, a kind of circular arc type exempts to follow closely antitheft door closer, is described further.
Embodiment 1:
A kind of circular arc type exempts to follow closely antitheft door closer, as shown in figure 1, including baffle plate 1, hammerlock 2, base 4, connecting bolt 3, described gear
Plate 1 bottom is provided with the supporting plate 101 matching with door 9 bottom, and described baffle plate 1 and supporting plate 101 are provided with buffering with door 9 touching position
Pad 8, described supporting plate 101 and baffle plate 1 are mutually perpendicular to, and the one side of described baffle plate 1 is contacted with door 9 face, and bearing pin 7 is passed through in another mirror image face
Hinged with hammerlock 2, described hammerlock 2 is in arc-shaped, and the circular arc bearing of trend of described hammerlock 2 movable end points to ground 10, described lock
It is provided with knob 201, described baffle plate 1 and hammerlock 2 hinged place are provided with for limiting the hinged activity model of hammerlock 2 in the middle part of arm 2
