Detailed Description
Referring to fig. 1 to 7, which schematically illustrate an enhanced lock base and lock point combination suitable for an oversized opening sash according to a first embodiment of the present invention, a lock base 10 is mounted on a window frame 30 of an opening sash 40, the opening sash 40 has a C-shaped groove 41 with a european standard, a transmission rod 42 is slidably disposed in the C-shaped groove 41, and a lock point 20 is mounted on the transmission rod 42.
The lock seat 10 comprises a rectangular base 11, an upper smoothly bent bulge 12 is arranged at the front end of the base 11, and a boss 13 with a right trapezoid cross section is arranged at the rear end of the base 11. A clamping groove 31 for clamping the lock base 10 is formed in the window frame 30, the clamping groove 31 comprises a bottom plate 32, two vertical baffle plates 33 are respectively arranged at two ends of the bottom plate 32, and a horizontally extending convex rib 34 is arranged on one of the baffle plates 33; the raised ribs 34 have a horizontal lower surface; when the lock base 10 is clamped in the clamping groove 31, the upper protrusion 12 of the lock base 10 is clamped against the lower surface of the protrusion rib 34, and the rear end surface of the base 11 is clamped against the other baffle 33.
The window frame 30 omits a traditional European standard C groove 41, adopts a novel clamping groove 31, utilizes a baffle 33 to clamp the rear end face of the base 11 and exposes the boss 13, utilizes a convex rib 34 to clamp the upper bulge 12 of the lock seat 10 at the other side, and mills an installation space of the wall thickness of the base 11 according to the size of an opening 35 of the clamping groove 31. The lock holder 10 can be inserted into the slot 31 by rotating the lock holder 10, and the installation is convenient (as shown in fig. 3). The base 11 has a mounting hole at the center thereof and is fixed in the slot 31 by a countersunk screw 50. The countersunk head screw 50 is fixed at a position where the bending moment and the shearing force of the lock seat 10 are small, and can reduce the stress concentration influence of the lock seat 10 caused by weakening of the screw hole.
When mounting, the lock holder 10, the window frame 30 and the beam or the pillar connecting the window frame 30 can be connected together by using the countersunk head screw 50, and the length of the countersunk head screw 50 is greater than the sum of the wall thicknesses of the lock holder 10, the window frame 30 and the beam or the pillar, so that the countersunk head screw 50 can effectively limit the displacement of the lock holder 10.
After the lock base 10 is clamped into the clamping groove 31, the protruding rib 34 restrains the Z-direction displacement of the lock base 10 within the full length range, and the baffle 33 located at the rear end face of the lock base 10 restrains the Y-direction displacement of the lock base 10 within the full length range. And countersunk screw 50 limits the displacement of lock seat 10 in X to and Z to, and the abundant joint cooperation of lock seat 10 and draw-in groove 31 has effectively avoided stress concentration, increases the bearing capacity of lock seat 10. Wherein, X is parallel to the direction of the glass panel of the opening sash, Y is perpendicular to the direction of the glass panel of the opening sash, and Z is the direction of self weight.
The lock base 10 is an integrally formed structure and is made of high-strength aluminum alloy, which may be 6061-T6, that is, the lock base 10 may be formed by extrusion of 6061-T6 aluminum alloy profile. The length of the lock base 10 can be adjusted according to the stress. The width of the upper end face a of the boss 13 is 4mm, the width of the lower end face b of the boss 13 is 5.5mm, and the height of the boss 13 is 8.5 mm.
An anchor rod 21 integrally extends from the locking point 20, the transmission rod 42 is provided with a through hole with the same diameter as the anchor rod 21, and the anchor rod 21 is riveted on the through hole. In use, the locking of the opening leaf 40 is achieved by the overlap of the locking point 20 with the boss 13. The locking point 20 is made of 304 stainless steel, and the height of the locking point 20 is 8.5 mm. The transmission rod 42 is made of 6061-T6 material, and the thickness of the transmission rod 42 is 3.2 mm; since the transmission rod 42 has a through hole with the same diameter as the anchor rod 21, the locking point 20 and the transmission rod 42 are riveted together by a spin riveting machine to form a rivet head 22 with a height of 1.1mm and a diameter of 7.0mm (within a tolerance range of +/-0.1 mm). The formed rivet head 22 is smooth and regular, and does not influence the sliding of the transmission rod 42 in the Europe standard C groove 41. The thickened transmission rod 42 is high in structural strength, good in adaptability with the European standard C groove 41, thickened in riveting thickness and enhanced in connection performance of riveting points. The design value of the lock point 20 of the present embodiment can reach 2.2 to 2.8 kN. Whereas the conventional lock point loading design value is only 0.8 kN.
Referring to fig. 8, when the lock point 20 overlaps the lock seat 10, the lock point 20 and the overlapping wall surface (boss 13) of the lock seat 10 transmit the concentrated load perpendicular to the panel c direction, the concentrated force F can make the upper end surface a of the boss 13 generate local pressure-bearing damage and deformation under the local pressure, while the utility model adopts the trapezoidal boss 13, the lower end surface b is thickened to 5.5mm, and the upper end surface a is thickened to 4 mm. The cross section of the boss 13 is thickened along with the increase of the arm of the concentrated force F, and is increased from 4mm to 5.5mm of the lower end face b (the position of maximum bending moment). The lower end face b bears the combined action of bending moment and shearing force, the shearing force is completely transmitted to the baffle 33 (the baffle 33 close to the right side in the figure) of the clamping groove 31, and the lock seat 10 and the window frame 30 are stressed cooperatively. The countersunk head screw 50 is fixed at a position with smaller bending moment and shearing force of the lock seat 10, so that the stress concentration influence of the lock seat 10 caused by weakening of screw holes is reduced. The lock seat 10 and the window frame 30 are fully connected, the functions of each contact point and each component are exerted, and the stress is reasonable.
Referring to fig. 9 to 11, the standard overlapping amount of the locking point 20 and the lock base 10 in the vertical direction is 5mm, that is, the standard overlapping amount of the locking point 20 and the boss 13 in the vertical direction is 5 mm. The vertical tolerance of the locking point 20 and the lock seat 10 is +/-3.5 mm, and the lap joint amount is 1.5mm when the locking point and the lock seat deviate to the limit position, so that the locking point and the lock seat are ensured to be safely matched. The lock point and lock seat combination has the characteristic of large adaptive deviation range.
Referring to fig. 12, for a standard lock case 10 with a handle formed as 18mm, the lock point 20 and the lock case 10 provided in this embodiment can achieve a tolerance of ± 2.5mm in the moving direction of the transmission rod 42, i.e., a window closing tolerance of ± 2.5mm, and at this time, a lock case 10 with a length of 21mm can be used. Referring to fig. 13-15, when greater window closing tolerances are required for special cases, the tolerance between the locking point 20 and the lock housing 10 in the direction of long travel of the drive rod 42 is ± 9mm, and a lock housing 10 of length 40mm can be used. The lock point and lock seat combination has the characteristic of strong tolerance capability.
Referring to fig. 16 to 18, the main structure of a second embodiment of the present invention is exemplarily shown. This embodiment differs from the first embodiment in that: a convex block 14 is further arranged at the end portion of the upper protrusion 12 of the lock base 10, an opening 35 corresponding to the convex block 14 is arranged on the protruding rib 34, and when the lock base 10 is clamped in the clamping groove 31, the convex block 14 is clamped in the opening 35. The length of the projection 14 is smaller than that of the upper projection 12, and the number of the projections 14 may be one or more. When the lock base 10 is clamped in the clamping groove 31, the convex block 14 can better limit the transverse and vertical displacement of the lock base 10 in the clamping groove 31, so that the clamping groove 31 and the lock base 10 have sufficient clamping surface matching, and any stress concentration is avoided.
In summary, the reinforced lock base and the lock point combination suitable for the oversized opening fan provided by the utility model have the advantages that when the lock base is arranged in the clamping groove, the upper bulge of the lock base is clamped against the lower surface of the convex rib, and the rear end face of the base is clamped against the other baffle plate, so that the deformation of the lock base is effectively resisted, the concentrated stress existing between the lock base and the clamping groove is reduced, and the lock base and the clamping groove have better bearing capacity. The transmission rod is provided with a through hole with the same diameter as the anchor rod, so that the locking point is tightly matched and riveted with the transmission rod, and the transmission rod has better bearing capacity.
Furthermore, the boss is of a structure with a right trapezoid cross section, namely, the unfavorable cross section of the lock base is thickened according to stress analysis, and the bearing capacity requirement under large load is met.
The above description is of the preferred embodiment of the present invention and the technical principles applied thereto, and it will be apparent to those skilled in the art that any changes and modifications based on the equivalent changes and simple substitutions of the technical solution of the present invention are within the protection scope of the present invention without departing from the spirit and scope of the present invention.
