Abstract
The invention relates to a novel anti-theft latch, which comprises a latch plate, a latch rod sleeve arranged on the latch plate, a latch rod embedded into the latch rod sleeve, and a latch nose arranged corresponding to the latch plate. The latch rod comprises a cross rod and a vertical rod; the vertical rod extends outwards along a direction perpendicular to the cross rod from one end, far away from the latch nose, of the cross rod; the latch rod further comprises a rotary rod; one end of the rotary rod is hinged with one end, close to the cross rod, of the vertical rod; at least one lug is further arranged on the latch plate; the thickness of each lug is less than the thickness of the vertical rod; and a check block is further arranged on one end, far away from the latch nose, of the latch plate. By adopting the structure, an anti-theft effect of the latch can be effectively improved, so that a safety performance is greatly ensured.
Description
Technical field
The present invention relates to a kind of novel anti-theft inserted pin.
Background technology
Used as a kind of simple structure, easy to use antitheft apparatus of fixing or lock, latch is obtained in daily life
Application widely.But the problems of at the same time it is that, after being plugged, the people being located outside is by letter for existing latch
Easy instrument is easy to pin rod is rotated at random and along the axial direction movement pin rod of pin rod, so as to easily by latch
To opening, therefore, the anti-theft effect of existing latch is unsatisfactory, there is larger potential safety hazard.
The content of the invention
To overcome above the deficiencies in the prior art, the technical problem to be solved in the present invention to be to provide one kind and can effectively improve
Anti-theft effect, so as to ensure that significantly the novel anti-theft inserted pin of security performance.
The technical scheme is that：A kind of novel anti-theft inserted pin, including pin plate, the pin rod set on pin plate, be embedded
Pin rod in pin rod set, and corresponding to the pin nose installed by pin plate, pin rod includes cross bar and montant, and montant from cross bar
The one end away from pin nose along stretching out perpendicular to the direction of cross bar, pin rod further comprises bull stick, and one end of bull stick with it is perpendicular
One end of the close cross bar of bar is additionally provided with least one projection, and the thickness of projection less than the thickness of montant on pin plate to be hinged
Degree, is additionally provided with block in one end away from pin nose of pin plate.
Length of the length of above-mentioned novel anti-theft inserted pin, wherein bull stick less than or equal to montant.
Above-mentioned novel anti-theft inserted pin, wherein being equipped with screw thread in one end of one end of bull stick and the close cross bar of montant
Hole, is attached by bolt between the screwed hole of the screwed hole and montant of bull stick.
The number of above-mentioned novel anti-theft inserted pin, wherein projection is 2.
Above-mentioned novel anti-theft inserted pin, wherein the length for being smaller than montant between 2 projections.
The invention has the beneficial effects as follows：The antitheft effect of latch can be effectively improved by adopting said structure, the present invention
Really so that be difficult to open latch from outdoor, so as to ensure that significantly its security performance.
Description of the drawings
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is described in further detail.
Fig. 1 is the structural representation of novel anti-theft inserted pin.
In figure：Pin plate 1, pin rod set 2, pin rod 3, pin nose 4, cross bar 5, montant 6, bull stick 7, projection 8, block 9, bolt 10.
Specific embodiment
As shown in figure 1, a kind of novel anti-theft inserted pin, including pin plate 1, the pin rod set 2 on pin plate 1, it is embedded in pin rod
Pin rod 3 in set 2, and corresponding to the pin nose 4 installed by pin plate 1, pin rod 3 includes cross bar 5 and montant 6, and montant 6 from horizontal stroke
Along stretching out perpendicular to the direction of cross bar 5, pin rod 3 further comprises bull stick 7 for one end away from pin nose 4 of bar 5, and bull stick 7
One end is to be hinged with one end of the close cross bar 5 of montant 6, and at least one projection 8, and the thickness of projection 8 are additionally provided with pin plate 1
Less than the thickness of montant 6, block 9 is additionally provided with one end away from pin nose 4 of pin plate 1.
As a kind of embodiment being articulated and connected, for above-mentioned novel anti-theft inserted pin, wherein in one end of bull stick 7 and
One end of the close cross bar 5 of montant 6 is equipped with screwed hole, passes through bolt 10 between the screwed hole of the screwed hole and montant 6 of bull stick 7
It is attached.
In actual use, when pin rod 3 is inserted to pin nose 4, first bull stick 7 is rotated to being overlapped with montant 6
Position, the angular way that then rotary bar 5 makes which to avoid projection 8 are inserted in pin nose 4, then rotary bar 5 again so that
Montant 6 is close to pin plate 1, and montant 6 is also placed between pin rod set 2 and projection 8（So just by the anteroposterior position of montant 6
Put fixation）, bull stick 7 is subsequently rotated again so that bull stick 7 is in the position shown in Fig. 1（So just can limit cross bar 5 carries out turning
It is dynamic）.By adopting said structure, just the cross bar 5 of latch and montant 6 firmly can be clamped and fastened on position as shown in Figure 1,
Can neither rotate, can not be moved rearwards by again, so that latch is difficult from outdoor to be opened, so as to substantially increase latch
Anti-theft effect, strengthens its security performance.
Preferably, for above-mentioned novel anti-theft inserted pin, wherein length of the length of bull stick 7 less than or equal to montant 6.This
Sample, is just more beneficial for bull stick 7 and is rotated in limited area of space.
Used as further preferably, for above-mentioned novel anti-theft inserted pin, the wherein number of projection 8 is 2, and further
Ground, wherein the length for being smaller than montant 6 between 2 projections 8.
In sum, the anti-theft effect of latch can be effectively improved by adopting said structure, the present invention so that from room
It is outer to be difficult to open latch, so as to ensure that significantly its security performance.
The preferred embodiments of the disclosure and embodiment are explained in detail above in conjunction with accompanying drawing, but it is of the invention
The above-described embodiment and examples are not limited to, in the ken that those skilled in the art possess, can be not taking off
Various changes can be made on the premise of the present inventive concept.
