[0003] The opening and closing methods of doors and windows can be divided into sliding type, casement type, lifting type, etc. In sliding doors and windows, due to the limitation of their own sliding structure, their sealing performance is poor and it is difficult to meet the requirements of some environments with high usage requirements. For this reason, some sliding doors and windows that can achieve side-pressing sealing have emerged on the market. After such doors and windows are slid and closed, by rotating the handle, the doors and windows can be gradually shifted towards the door frame direction, and the sealing strips on the doors and windows are tightly pressed against the door frame, thereby improving the sealing performance when the doors and windows are closed.

[0004] Among them, in order to realize the locking and fixing of doors and windows, a lock point structure is usually required to be arranged on the transmission bar. The existing lock point structures on the market are usually as Figure 1 shown, which includes a lock pin and a fixing seat arranged on the lock pin, and the fixing seat is clamped in the transmission bar. With such an arrangement, when the lock pin is subjected to a large lateral force (the lateral direction is the front-back direction in the figure), the fixing seat is likely to disengage from the transmission bar, causing the position of the lock pin to shift, and further resulting in the failure of the lock point structure to lock the doors and windows.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0034] Embodiment 1

[0035] Refer to Figures 2-5, the present utility model provides a locking point structure 1 for a push-pull side-pressing door and window, including a base 11, a locking pin 12, and a locking pin sleeve 13. The base 11 passes through the transmission bar 2 from the back side of the transmission bar 2, and the locking pin 12 is fixedly connected to the base 11 from the front side of the transmission bar 2; the locking pin sleeve 13 is located on the front side of the transmission bar 2 and sleeved on the outer periphery of the locking pin 12. Wherein, a first limiting convex ring 131 is provided on the locking pin sleeve 13. When the locking pin 12 is connected to the base 11, the first limiting convex ring 131 on the locking pin sleeve 13 abuts against the front side of the transmission bar 2 in a mating manner.

[0036] Thus, by sleeving the locking pin sleeve 13 on the locking pin 12, and the first limiting convex ring 131 which abuts against the front side of the transmission bar 2 is provided on the locking pin sleeve 13. With such a setting, when the locking pin 12 is subjected to a large lateral force, the position of the locking pin 12 can be prevented from shifting through the abutting cooperation between the first limiting convex ring 131 and the transmission bar 2, thereby ensuring the stable and firm position of the locking pin 12, and thus improving the stability and reliability of the locking point structure 1.

[0037] Furthermore, an axle pad 14 is further included and arranged between the locking pin sleeve 13 and the locking pin 12. A second limiting convex ring 141 is provided on the axle pad 14, and the second limiting convex ring 141 is located between the first limiting convex ring 131 and the front side of the transmission bar 2. Preferably, the axle pad 14 is made of a plastic material.

[0038] Thus, by providing the axle pad 14, direct contact between the locking pin sleeve 13 and the transmission bar 2 can be avoided, resulting in wear. And when the axle pad 14 is worn, it is also convenient to disassemble and replace it, with simple and convenient operation.

[0039] Referring again to Figures 2-5 , specifically, a threaded hole 112 is formed on the base 11. One end of the locking pin 12 is provided with a screw rod portion 121 that is threadedly connected to the threaded hole 112. The other end of the locking pin 12 is provided with a nut portion 122, and an adjustment hole 123 that can cooperate with an external adjustment tool is formed on the nut portion 122; preferably, the adjustment hole 123 is a hexagonal groove hole; the locking pin sleeve 13 includes a first body in a sleeve shape, and the first limiting convex ring 131 is annularly arranged on the outer side wall of the first body. Wherein, a first through groove 132 for the axle pad 14 and the locking pin 12 to pass through is formed inside the first body, and a step surface 133 that can abut against the nut portion 122 of the locking pin 12 is provided on the first through groove 132; the axle pad 14 includes a second body in a sleeve shape, and the second limiting convex ring 141 is annularly arranged on the outer side wall of the second body. Wherein, a second through groove 142 for the locking pin 12 to pass through is formed inside the second body, a snap ring 143 is annularly arranged on the inner side wall of the second through groove 142, and a card slot 124 that is snap-fitted with the snap ring 143 is annularly arranged on the outer side wall of the locking pin 12.

[0040] Thus, when it is necessary to assemble the locking point structure 1, first, the shaft pad 14 is sleeved on the outer periphery of the locking pin 12 through the second through groove 142 of the shaft pad 14 until the snap ring 143 is engaged with the card slot 124. At this time, the assembly of the shaft pad 14 and the locking pin 12 is completed. Subsequently, the second body of the shaft pad 14 is inserted into the first through groove 132 of the locking pin sleeve 13, and the second limiting convex ring 141 abuts against the first limiting convex ring 131 to achieve limiting, thereby realizing the preliminary positioning of the locking pin sleeve 13 and the locking pin 12. Then, after the locking pin 12 is fixedly connected to the base 11 by threading, the nut portion 122 on the locking pin 12 abuts against the step surface 133 of the locking pin sleeve 13 and drives the locking pin sleeve 13 to be pressed and fixed. At this time, the first limiting convex ring 131 is pressed against the transmission bar 2 through the second limiting convex ring 141, and thus the assembly of the locking point structure 1 is completed.
