Description

Technical Field

[0001] This utility model relates to the technical field of door and window accessories, and in particular to a lock body accessory for doors and windows. Background Technology

[0002] Sliding windows are a common type of window, widely used due to their advantages such as not taking up indoor space, flexible opening, and low price. To improve the airtightness of sliding windows, a side-pressure window has also been developed. Locking points and lock seats are commonly used accessories for sliding doors and windows. Generally, locking points and lock seats work together to achieve functions such as locking doors and windows. The installation of locking points and lock seats is also very convenient. Generally, locking points and lock seats have inserts. The inserts are inserted into the hardware channels of the profile, and the lock seat or locking point is fixed with screws. Then, the drive rod is connected by the pins on the locking point or lock seat to complete the installation. However, because there is a certain gap between the insert and the hardware channel, the locking point and lock seat will rub against the profile during operation, making noise. At the same time, it is also easy to wear the locking point or lock seat. In addition, the locking point or lock seat only relies on the drive rod to slide, which can cause loosening during the sliding process. Utility Model Content

[0003] The present invention provides a lock body accessory for doors and windows to solve the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lock body accessory for doors and windows, comprising a locking point and a lock seat, wherein both the locking point and the lock seat include a plate, and inserts are provided on the front and rear sides of the plate, and rubber sleeves are provided on both sides of the upper side of the plate. Abutment strips are provided on the front and rear sides of the two rubber sleeves protruding toward the inserts, one end of the abutment strip is elastically connected to the rubber sleeve, and the other end is provided with a bent portion, the bent portion protruding outward from the insert.

[0005] Furthermore, the plate is convex in shape, and the two rubber sleeves are respectively disposed in the recesses on the upper sides.

[0006] Furthermore, the plate has supports for connecting the transmission rod in the recesses on both sides, and the rubber sleeve has round holes corresponding to the supports.

[0007] Furthermore, positioning blocks are provided at both ends of the insert, and a positioning hole for inserting the positioning block is provided at the end of the abutment strip away from the bend.

[0008] Furthermore, the abutment strip is aligned with the insert.

[0009] Furthermore, the adhesive sleeve is bonded to the plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by setting rubber sleeves on the locking points and locking seats, the rubber sleeves are used to isolate direct contact with the profile, preventing noise and wear on the locking points and locking seats. At the same time, the abutting strip is set, and its bent part abuts against the wall of the hardware groove. The abutting strip has a certain elasticity and can keep abutting against the hardware groove outward, filling the gap between the insert and the hardware groove, and preventing the locking points or locking seats from loosening during the sliding process.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] As shown in the attached diagram, this utility model discloses a lock body accessory for doors and windows, comprising a locking point 1 and a lock seat 2. Both the locking point 1 and the lock seat 2 include a plate 10. For example, the locking point 1 further includes a locking pin disposed on the plate 10, and the lock seat 2 further includes a mating groove disposed on the plate 10. This is an existing structure and will not be described in detail. It should be noted that the locking point 1 and the lock seat 2 cooperate with each other; one is a movable part, driven to slide by a transmission rod, and the other is a fixed part, which can be directly fixed into the hardware groove. Inserts 20 are protruding from the front and rear sides of the plate 10. Both sides of the upper side of the plate 10 are provided with rubber sleeves 30. Abutment strips 31 are protruding from the front and rear sides of the two rubber sleeves 30 toward the inserts 20. One end of the abutment strip 31 is elastically connected to the rubber sleeve 30, and the other end is provided with a bent part 311. The bent part 311 protrudes outward from the insert 20 and is close to the insert 20. A certain gap is reserved between the bent part 311 and the insert 20 for the bending part 311 to deform.

[0018] This utility model discloses a lock body accessory for doors and windows. By setting rubber sleeves 30 on the locking point 1 and the lock seat 2, the rubber sleeves 30 are used to isolate direct contact with the profile, preventing noise and wear on the locking point 1 and the lock seat 2. At the same time, the abutment strip 31 is set, and its bent part 311 abuts against the wall of the hardware groove. The abutment strip 31 has a certain elasticity and can keep abutting against the hardware groove outward, filling the gap between the insert 20 and the hardware groove, and preventing the locking point 1 or the lock seat 2 from loosening during the sliding process.

[0019] refer to Figure 3 The plate 10 is convex in shape, with two rubber sleeves 30 respectively located in the recesses on both sides of the upper side, i.e., the two rubber sleeves 30 are symmetrically placed on both sides of the plate 10. The plate 10 has support pillars 300 for connecting the transmission rod in the recesses on both sides. The rubber sleeves 30 have circular holes 3000 corresponding to the support pillars 300. The support pillars 300 connected to the transmission rod cooperate with the circular holes 3000 to assist in positioning the rubber sleeves 30. Positioning blocks 100 are provided at both ends of the insert 20. The end of the abutment strip 31 away from the bent portion 311 has a positioning hole 312 for inserting the positioning block 100. Since the abutment strip 31 is only connected to the surface of the rubber sleeve 30 at one end, and the plastic material itself is elastic, the cooperation of the positioning block 100 and the positioning hole 312 effectively prevents the abutment strip 31 from shifting.

[0020] A positioning protrusion can also be provided on the rubber sleeve 30. The locking point 1 / lock seat 2 is provided with a positioning hole 312 for the positioning protrusion to be inserted, which is also used for positioning the rubber sleeve 30 to prevent the rubber sleeve 30 from falling off the plate 10.

[0021] Specifically, the abutment strip 31 is aligned with the insert 20 to ensure that the abutment strip 31 and the insert 20 can be inserted into the hardware groove together during installation, and the bent part 311 of the abutment strip 31 abuts against the wall of the hardware groove.

[0022] Specifically, the adhesive sleeve 30 is bonded to the plate 10. The adhesive sleeve 30 has an L-shaped face that is close to the recess of the plate 10. The face and the plate 10 can be directly fixed with glue to prevent the adhesive sleeve 30 from falling off.

[0023] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
