Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the locking point device of the present embodiment includes a base 1, an adjusting seat 2, and an adjusting member 3. The base 1 is provided with an installation cavity 11 with an opening at the front end; the adjusting seat 2 is arranged in the mounting cavity 11 and can move back and forth in the mounting cavity 11, and a locking point 4 extending out of the mounting cavity 11 is arranged on the adjusting seat 2; the adjusting piece 3 is in threaded connection with the adjusting seat 2, one end of the adjusting piece 3 is rotatably connected to the bottom of the mounting cavity 11, and the other end of the adjusting piece is provided with an operating part 31. Preferably, in order to realize the threaded connection between the adjusting part 3 and the adjusting seat 2, an internal thread through hole can be formed in the adjusting seat 2, and an external thread matched with the internal thread is formed in the adjusting part 3. One end of the adjusting member 3 is rotatably connected to the bottom of the mounting cavity 11, so that the adjusting member 3 can rotate without moving in the axial direction. The operation portion 31 is used for connecting with an external tool or as a structure that can be twisted by fingers so as to rotate the adjusting member 3 by means of the external tool or the fingers, and when the operation portion is used for connecting with the external tool, it can be set as a hexagonal counter bore, a cross counter bore, a sub counter bore, etc. so that the adjusting member 3 can be rotated by means of a tool such as a hexagonal wrench, a cross screwdriver, a sub screwdriver, etc. Through setting up front end open-ended installation cavity 11 on base 1, but set up regulation seat 2 of back-and-forth movement in installation cavity 11, set up lock point 4 on adjusting seat 2 to with regulating part 3 and regulation seat 2 threaded connection, and with the rotatable bottom of connecting in installation cavity 11 of one end of regulating part 3, the other end sets up operation portion 31. When adjusting the fore-and-aft position of lock point 4, only need twist through operation portion 31 and move regulating part 3, because regulating part 3 and regulation seat 2 threaded connection, can promote when regulating part 3 rotates and adjust the back-and-forth movement of seat 2 to adjust the fore-and-aft position of lock point 4, convenient operation.

As shown in fig. 1-4, a narrowing table 12 is disposed at an opening position of the mounting cavity 11, and a flange 21 capable of blocking the narrowing table 12 is disposed on the adjusting seat 2. The narrowing table 12 and the flange 21 are designed to limit the limit position of the forward movement of the adjusting seat 2, so that the adjusting seat 2 can be prevented from being separated from the mounting cavity 11. For sharing the power that lock point 4 was strikeed (including the front striking that probably takes place when closing door and window or the reverse of probably taking place when opening door and window drags), be equipped with on the lateral wall of installation cavity 11 a plurality of with the parallel protruding muscle 13 of axis of installation cavity 11, be equipped with on the regulation seat 2 with the recess 22 that protruding muscle 13 position corresponds, protruding muscle 13 card is located in the recess 22. Under the non-limit state, a certain gap exists between the flange 21 of the adjusting part 3 and the narrowing platform 12, the adjusting seat 2 is separated from the bottom of the installation cavity 11 by the adjusting part 3, the end where the locking point 4 is located is suspended in the installation cavity 11, when the locking point 4 is impacted, the impact force is transmitted to the adjusting seat 2, so that the adjusting seat 2 deforms (or has a deformation tendency), and due to the existence of the convex rib 13 and the groove 22, the deformation of the adjusting seat 2 can enable the groove wall of the groove 22 to compress the convex rib 13, so that the impact force is transmitted to the convex rib 13; and because one end of the adjusting piece 3 is connected to the bottom of the installation cavity 11, after the convex rib 13 shares the impact force, the rest part of the impact force is transmitted to the bottom of the installation cavity 11 through the adjusting piece 3. Therefore, most of the impact force is shared, and only a small amount of force acts on the connecting thread between the adjusting piece 3 and the adjusting seat 2, so that the damage to the connecting thread is effectively reduced, and the service life and the stability of the locking point device are higher. Further, for better sharing the force of the locking point 4 being hit, the locking point 4 is disposed at one end of the adjusting seat 2, and the adjusting member 3 is disposed at the other end of the adjusting seat 2 far away from the locking point 4. The locking point 4 and the adjusting piece 3 are respectively arranged at two opposite ends of the adjusting seat 2, so that the distance between the locking point 4 and the adjusting piece is longer, the adjusting seat 2 is easier to deform when the locking point 4 is impacted, and more impact force is shared by the convex ribs 13; the lock point 4 is farther from the adjusting piece 3, so that the adjusting piece 3 can be operated by an external tool more conveniently, and the interference with the lock point 4 can be avoided when the adjusting piece 3 is operated.

As shown in fig. 1, 4, and 5, in order to adjust the eccentric position of the locking point 4 (when the door and window frame and the door and window sash are not in the same plane range, the locking point 4 and the locking hole seat are easily misaligned, so that the eccentric position needs to be adjusted), the locking point 4 includes a locking head 41 provided with a boss 411 and a connecting column 42 eccentrically disposed with the locking head 41, the adjusting seat 2 is provided with a connecting hole 23, and the connecting column 42 is rotatably disposed in the connecting hole 23. The adjustment of the eccentric position is a conventional adjustment and will not be described in detail here. For the better impact transmission that receives lock point 4 for adjusting seat 2, lock point 4 still includes and keeps off platform 43, tapered end 41 set up in the one end of keeping off platform 43, spliced pole 42 set up in the other end of keeping off platform 43, just keep off the surface that platform 43 was equipped with spliced pole 42 one end and support and lean on adjust seat 2 surface.

As shown in fig. 1, 2 and 6, the base 1 includes an inner housing 14 and a bottom plate 15; the inner base 14 is provided with a cavity 141, the bottom plate 15 is blocked at the bottom of the cavity 141 to form the mounting cavity 11, and one end of the adjusting member 3 is rotatably connected to the bottom plate 15. A cylindrical table 32 is arranged at one end of the adjusting part 3, which is connected with the bottom plate 15, and a positioning hole 151 corresponding to the cylindrical table 32 is arranged on the bottom plate 15; when the adjuster 3 is rotated by the operating portion 31, the cylindrical table 32 rotates in the positioning hole 151. The locking device comprises a transmission strip 5, the base 1 further comprises an outer shell 16 connected with the transmission strip 5, and the outer shell 16 is coated outside the inner base 14. The driving strip 5 and the outer shell 16 are integrally formed plastic pieces. The base 1 is designed to include an inner housing 14, a bottom plate 15 and an outer housing 16 for easy processing and assembly. Preferably, the cylindrical table 32 is riveted to the positioning hole 151, but can rotate within the positioning hole 151. The transmission strip 5 with shell body 16 sets up to integrated into one piece's working of plastics, interior pedestal 14 and bottom plate 15 are the metalwork for the wholeness of lock point device is better, has also improved the structural strength and the reliability of lock point device, and the cost is also lower.

It should be understood that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same, and those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some technical features; and all such modifications and alterations should fall within the scope of the appended claims.
