In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
The present invention will be described below by taking the first body and the second body as the splice plates, respectively. It should be appreciated that the latch may also be used with bodies other than splice plates, such as cases, cabinets, doors, and the like.
Referring to fig. 1 to 9, the invention provides a lock catch for splice plates, which is characterized by comprising a lock catch module and a driving module, wherein the lock catch module comprises a pull buckle 3 mounted on a first splice plate and an angle pin rack 4 mounted on a second splice plate and adapted to the pull buckle 3, the pull buckle is provided with a first insertion hole 31, and the first insertion hole 31 has a hole width enough to accommodate the angle pin rack 4;
the driving module is used for driving the angle pin rack 4 to move transversely, so that the angle pin rack 4 is clamped with or separated from the first insertion hole 31 of the tab 3 at the buckling position.
From the above description, the beneficial effects of the present invention are: the taper pin rack is inserted into the jack of the pull buckle under the driving of the driving module to achieve the effect of locking the first splicing plate and the second splicing plate, because the face of the taper pin rack clamped with the jack of the pull buckle is an inclined face, when the distance deviation between the first splicing plate and the second splicing plate is large, the clamping occurs at the narrow part of the width of the taper pin rack, when the distance deviation between the first splicing plate and the second splicing plate is small, the clamping occurs at the wide part of the width of the taper pin rack, therefore, when the distance deviation between the first splicing plate and the second splicing plate is in a large range, the lock catch structure can well fix the two splicing plates.
Further, the tilt-pin rack 4 has a toothed bottom edge 41 and a tilt edge 42 inclined with respect to the bottom edge 41, the tilt edge 42 forming an inclination angle of less than 6 degrees with respect to the bottom edge 41.
From the above description, the inclination angle of the bevel edge of the taper pin rack is smaller than the self-locking angle of the steel material.
Further, the hole wall 311 of the first insertion hole 31 has the same inclination direction and inclination angle as the inclined edge 42 of the taper pin rack 4.
It can be known from the above description that the jack has the pore wall of the slope that the incline direction and the inclination of the hypotenuse of taper pin rack are the same for the pore wall of the slope of jack can contact completely with the hypotenuse of taper pin rack, and inclination is less than the auto-lock angle of steel, makes no matter how big external force that the tab exerted on the taper pin rack, can not take place to slide between jack and the taper pin rack, therefore makes this hasp structure can be used for locking two concatenation objects that weight is heavier.
Further, the pull buckle 3 is installed on a first base 1 on a first splice plate, and the angle pin rack 4 is installed on a second base 2 on a second splice plate;

According to the description, the rotating hand wheel is rotated, and the hand wheel gear rotates along with the rotating hand wheel gear to drive the angle pin rack to move transversely; the gear rack transmission mode is adopted, the service life is long, the work is stable, the reliability is high, the rotating hand wheel does not need to move along with the movement of the angle pin rack, and the installation space is greatly saved.
Furthermore, a pull buckle rotating shaft 32 is arranged at the bottom end of the pull buckle 3, and the pull buckle rotating shaft 32 is installed on the first base 1 through a pull buckle compression screw 6, so that the pull buckle 3 rotates around the first base 1. In one example, the tab rotation axis 32 is arranged parallel to the splice plate surface, i.e. the tab 3 rotates around the first base 1 perpendicular to the splice plate surface to snap into the second base.
Further, a first bead positioning groove 33 is formed in the pull buckle rotating shaft 32, and a first positioning bead 13 matched with the first bead positioning groove 33 is formed in the first base 1.

Furthermore, a tab protrusion 34 is arranged at the top end of the tab 3, and a third groove 22 matched with the tab protrusion 34 is arranged on the second base 2.
From the above description, after the zipper is closed, the lock catch structure can bear the self weight of the spliced object to prevent the spliced object from sliding off.
Further, a second bead positioning groove 43 is formed in the angle pin rack 4, and a second positioning bead 25 matched with the second bead positioning groove 43 is formed in the second base 2.
From the above description, when the taper pin rack is not engaged with the tab jack, the positioning bead is engaged in the taper pin rack bead positioning groove, thereby achieving the initial position positioning of the taper pin rack.
Further, the angle pin rack 4 is installed in an angle pin groove 23 matched with the angle pin rack pressing plate 7 through the angle pin rack pressing plate 7, and the angle pin groove 23 is fixed on the second base 2.

By adopting the positioning pin structure driven by the rack, the positioning mechanism is small, the action is stable and reliable, the phenomenon of locking cannot occur, and the operation is flexible.
Further, the positioning mechanism further comprises a fan-shaped block 8 clamped between the first base 1 and the second base 2, the fan-shaped block 8 has an arc angle of 0-40 degrees in a direction perpendicular to the splicing surfaces of the first splicing plate and the second splicing plate, and the positioning pin rack 9 is inserted into the fan-shaped block 8 before being inserted into the positioning hole 24.
Further, the segment 8 has a segment center hole 81 through which the positioning pin rack 9 passes, and has a segment protrusion 82 inserted into the positioning hole 24.
According to the description, the sector block with the radian angle is added into the positioning mechanism, so that the positioning is more stable and reliable when the radian is spliced, and the two splicing plates spliced by the radian are more firmly fixed by the lock catch.
