Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and more specifically to a locking structure and doors and windows. Background Art

[0002] In the field of door and window hardware fittings, a lock base and a lock rod cooperate with each other to play a key role in locking and unlocking doors and windows. The common installation method is as follows: the lock base or the lock rod is fixedly installed on the door and window frame part, and the corresponding lock rod or lock base is movably installed through a slot on the door and window sash part. With the continuous development and update of the industry, the traditional styles of lock bases and lock rods are difficult to meet the strict requirements of the current market in terms of price, installation convenience, etc.

[0003] For example, the existing lock base or lock rod is usually fixed on the frame part by means of a clamping block and a connecting piece, such as a clamping block and a self-tapping screw. The installation positions of the clamping block and the self-tapping screw are separately designed at both ends of the lock base or lock rod, so that the lock base or lock rod needs to be lengthened to a suitable space to accommodate the clamping block and the self-tapping screw. As a result, when the lock base and the lock rod cooperate, their lengths need to be increased to avoid interference. This method increases the material cost and causes unnecessary waste of resources. And usually, a screw and a nut are used to rotate and clamp the clamping block, and the nut and the clamping block are arranged inside the frame part. It is not easy to insert the screw into the nut and the clamping block, and it is also not conducive to adjusting the direction of the clamping block, which causes great inconvenience to the installation of the lock base or lock rod and affects the overall manufacturing and processing efficiency of the doors and windows.

[0049] Embodiment 1

[0050] See Figure 1-2 As shown, this embodiment discloses a locking structure 10, which is applied to doors and windows. The doors and windows include a frame part 20 and a sash part 30 that can be opened and closed relative to each other.

[0051] The locking structure 10 includes:

[0052] A first locking member 11, the first locking member 11 is fixedly arranged on the frame part 20 and is provided with a shaft hole 111 therethrough;

[0053] A second locking member 12, the second locking member 12 is slidably arranged on the sash part 30; the first locking member 11 is a lock base or a lock rod, and the second locking member 12 is a lock rod or a lock base corresponding to the first locking member 11;

[0054] A clamping block 13, the clamping block 13 is rotatably arranged on the first locking member 11 for clamping the frame part 20, and the clamping block 13 is provided with a first through hole 131;

[0055] The rotating shaft 14 is rotatably connected to the shaft hole 111. The rotating shaft 14 extends through the shaft hole 111 to the first through hole 131 and is connected to the first through hole 131. The rotating shaft 14 is used to drive the clamping block 13 to rotate so that the clamping block 13 clamps the frame portion 20. The rotating shaft 14 is provided with a second through hole 141, and the second through hole 141 is used to accommodate the connecting member 40, and the connecting member 40 is used to connect the first locking member 11 and the frame portion 20.

[0056] In the locking structure 10 of this embodiment, by providing the rotating shaft 14 to drive the clamping block 13 to rotate, when the locking structure is installed, the clamping block 13 is pre-placed in the frame portion 20, and rotating the rotating shaft 14 can realize the position adjustment of the clamping block 13 on the frame portion 20, facilitating the clamping block 13 to clamp the frame portion 20, and further realizing the fixation of the first locking member 11, significantly improving the installation convenience of the clamping block 13; by providing the second through hole 141 on the rotating shaft 14, the connecting member 40 can pass through and be connected to the rotating shaft 14, the clamping block 13 and the frame portion 20 in sequence, enhancing the connection stability between the first locking member 11 and the frame portion 20, and the installation positions of the connecting member 40 and the clamping block 13 are integrated into the rotating shaft 14, greatly reducing the lengths of the lock seat and the lock rod, saving material and space resources, and reducing the production and processing costs of the doors and windows.

[0057] In this embodiment, the connecting member 40 is a self-tapping screw. The self-tapping screw has high pull-out resistance and good thread locking effect, ensuring a firm connection between the first locking member 11 and the frame portion 20, and there is no need to preset thread lines and equip nuts in advance, reducing the processing steps and the use of materials, promoting the efficient assembly of the doors and windows, and at the same time improving the economic benefits of the doors and windows.

[0058] Specifically, one end of the rotating shaft 14 away from the clamping block 13 is further provided with a receiving groove 142, and the receiving groove 142 communicates with the second through hole 141; the aperture of the second through hole 141 is smaller than the width of the opening of the receiving groove 142. The receiving groove 142 is provided at the end of the second through hole 141 for receiving the wrenching end of the self-tapping screw, avoiding the wrenching end of the self-tapping screw from protruding outside the rotating shaft 14 and hindering the movement of the second locking member 12 on the first locking member 11, making the structure of the rotating shaft 14 more compact, ensuring that the first locking member 11 and the second locking member 12 do not interfere with each other, and ensuring the smooth progress of the locking and unlocking actions of the doors and windows; the setting of the receiving groove 142 also provides a limiting effect on the movement of the self-tapping screw, avoiding the risk that the self-tapping screw sinks too deep in the second through hole 141 and causes the rotating shaft 14 to be bent or broken, and also preventing the self-tapping screw from falling off from the second through hole 141, ensuring the structural stability of the locking structure 10.

[0059] Specifically, the cross-section of the second through-hole 141 is polygonal. The second through-hole 141 being polygonal facilitates the insertion of a corresponding polygonal wrench and enables the polygonal wrench to be clamped with the second through-hole 141, so as to rotate the rotating shaft 14 by rotating the polygonal wrench, reducing the difficulty of rotating the rotating shaft 14 and improving the convenience of rotating the rotating shaft 14, thereby improving the installation efficiency of the locking structure 10 and the doors and windows; moreover, the polygonal second through-hole 141 can provide a larger accommodation space for self-tapping screws compared to through-holes such as cross holes and star holes.

[0060] In this embodiment, the cross-section of the second through-hole 141 is regular hexagonal. The regular hexagonal second through-hole 141 facilitates the insertion of a regular hexagonal wrench and drives the rotation of the rotating shaft 14. The second through-hole 141 has six surrounding flat inner walls, increasing the contact area between the self-tapping screw and the second through-hole 141, facilitating the self-tapping screw to spin threads on the inner wall of the second through-hole 141 and being tightly connected to the second through-hole 141.

[0061] Embodiment Two

[0062] See Figure 3-6 As shown, this embodiment discloses a locking structure 10. Based on Embodiment One, the difference from Embodiment One is that the clamping block 13 and the rotating shaft 14 are of an integrated structure; one end of the rotating shaft 14 away from the clamping block 13 is riveted or screwed to the shaft hole 111. The integrated setting of the clamping block 13 and the rotating shaft 14 in this embodiment helps to achieve the stable rotation of the clamping block 13 following the rotating shaft 14. After the clamping block 13 is assembled in place, the rotating shaft 14 is fixed to the shaft hole 111 by riveting or screwing, realizing the fixation of the rotating shaft 14 and the first locking member 11, and further realizing the stable connection between the clamping block 13 and the first locking member 11.

[0063] The installation steps of the locking structure 10 in this embodiment: Rivet or screw the rotating shaft 14 to the shaft hole 111; Place the integrated structure of the clamping block 13 and the rotating shaft 14 in the frame groove of the frame portion 20; Insert and clamp the wrench into the second through-hole 141; Rotate the wrench until the clamping block 13 clamps the frame groove of the frame portion 20; Remove the wrench; Drive a self-tapping screw into the second through-hole 141, so that the self-tapping screw sequentially passes through the second through-hole 141, the first through-hole 131 and the frame portion 20, and is tightly connected to the rotating shaft 14, the clamping block 13 and the frame portion 20.

[0064] Embodiment Three

[0065] See Figure 2 and Figure 7-9As shown in the figure, this embodiment discloses a locking structure 10. Based on Embodiment 1, the difference from Embodiment 1 is that the rotating shaft 14 is provided with a connecting portion 143 and a limiting portion 144. The connecting portion 143 passes through the shaft hole 111 and is riveted or screwed to the clamping block 13. The limiting portion 144 is arranged at one end of the connecting portion 143 away from the clamping block 13. The maximum width of the connecting portion 143 is smaller than the aperture of the shaft hole 111, and the minimum width of the limiting portion 144 is larger than the aperture of the shaft hole 111. The shaft hole 111 is located between the limiting portion 144 and the clamping block 13. In this embodiment, the rotating shaft 14 and the clamping block 13 are separately arranged, and the limiting portion 144 and the clamping block 13 respectively limit the first locking member 11 from both sides, ensuring that the rotating shaft 14 will not break away from the first locking member 11, and realizing the stable connection between the rotating shaft 14 and the first locking member 11.

[0066] The installation steps of the locking structure 10 in this embodiment are as follows: Place the clamping block 13 in the frame groove of the frame portion 20; Pass the rotating shaft 14 through the shaft hole 111; Rivet or screw the rotating shaft 14 to the clamping block 13; Insert the wrench and engage it with the second through hole 141; Rotate the wrench until the clamping block 13 clamps the frame groove of the frame portion 20; Remove the wrench; Drive a self-tapping screw into the second through hole 141 so that the self-tapping screw sequentially passes through the second through hole 141, the first through hole 131 and the frame portion 20, and is fixedly connected to the rotating shaft 14, the clamping block 13 and the frame portion 20.

[0067] In this embodiment, the cross-section of the connecting portion 143 is a regular hexagon, and the first through hole 131 is arranged corresponding to the outer shape of the connecting portion 143. The outer wall of the connecting portion 143 is adapted to the inner wall of the first through hole 131, which is convenient for the connecting portion 143 to engage with the first through hole 131 and drive the clamping block 13 to rotate, improving the connection stability between the connecting portion 143 and the clamping block 13 and the riveting convenience between the rotating shaft 14 and the clamping block 13.

[0068] Specifically, the first locking member 11 is further provided with a limiting groove 112, the limiting groove 112 communicates with the shaft hole 111, and the aperture of the shaft hole 111 is smaller than the notch width of the limiting groove 112. The limiting groove 112 is used to accommodate the limiting portion 144. The limiting groove 112 is arranged corresponding to the limiting portion 144 and is used to accommodate the limiting portion 144, avoiding the limiting portion 144 from protruding from the surface of the first locking member 11 and hindering the movement of the second locking member 12, and improving the compactness and stability of the locking structure 10.

[0069] Embodiment 4

[0070] See Figure 10-13 As shown in the figure, this embodiment discloses a locking structure 10. Based on Embodiment 3, the difference from Embodiment 3 is that the first locking member 11 is a lock base and the second locking member 12 is a lock rod.

[0071] Specifically, the lock base includes:

[0072] The bottom plate 113 is horizontally arranged, and the shaft hole 111 penetrates through the bottom plate 113.

[0073] The vertical plate 114 is vertically arranged on the top surface of the bottom plate 113.

[0074] The panel 115 is arranged parallel to the bottom plate 113 and is fixedly connected to the top end of the vertical plate 114.

[0075] The panel 115 includes a clamping portion 1151 and an installation portion 1152; the clamping portion 1151 is fixedly connected to the vertical plate 114, and the installation portion 1152 is fixedly connected to the side surface of the clamping portion 1151 away from the vertical plate 114; the length of the installation portion 1152 is less than the length of the clamping portion 1151; the installation portion 1152 is provided with a third through hole 11521 corresponding to the shaft hole 111, and the third through hole 11521 is used to accommodate the rotating shaft 14.

[0076] The lock base of this embodiment is arranged in a double layer. The rotating shaft 14 passes through the installation portion 1152 and the bottom plate 113 in sequence and is connected to the clamping block 13. When an external force acts on the side of the lock base, such as when the end of the clamping portion 1151 receives the abutting force of the lock rod, the rotating shaft 14 provides a restraining effect on the panel 115, disperses and resists the external force, making the panel 115 and the lock base as a whole more stable, improving the stress intensity and durability of the lock base; and the clamping portion 1151 and the installation portion 1152 are connected to the vertical plate 114 in a "T" shape, saving the material of the panel 115 and reducing the production and processing cost of the doors and windows.

[0077] Specifically, the rotating shaft 14 is further provided with a support portion 145. The support portion 145 is arranged between the limiting portion 144 and the connecting portion 143. The limiting portion 144 is located at the end of the installation portion 1152 away from the bottom plate 113, and the support portion 145 is located between the installation portion 1152 and the bottom plate 113; the minimum width of the support portion 145 is greater than the aperture of the shaft hole 111, the aperture of the third through hole 11521 is greater than the maximum width of the support portion 145, and the minimum width of the limiting portion 144 is greater than the aperture of the third through hole 11521. Preferably, the limiting groove 112 is arranged on the installation portion 1152 and communicates with the third through hole 11521. The structure of the rotating shaft 14 adapts to the setting of the lock base. From the end far from the clamping block 13 to the end close to it, they are the limiting portion 144, the support portion 145, and the connecting portion 143 respectively. The support portion 145 provides a supporting force for the panel 115, enhancing the structural stability of the locking structure 10. At the same time, it avoids a large gap between the connecting portion 143 and the shaft hole 111, resulting in the rotating shaft 14 being easily deviated from the central axis during rotation or fixation, improving the compactness and reliability of the locking structure 10.

[0078] Specifically, the lock base is further provided with a screw hole 116 for passing through a self-tapping screw. The self-tapping screw in the screw hole 116 is screwed into the frame portion 20, and the setting of the screw hole 116 improves the connection stability of the lock base.

[0079] Example 5

[0080] See Figure 14-16 As shown, this embodiment discloses a locking structure 10. Among them, Figure 14-16 All are shown by taking the locking rod as the second locking member 12 as an example. The locking structure 10 of this embodiment is based on Embodiment 1, and the difference from Embodiment 1 is that: convex platforms 121 and fourth through holes 122 are respectively provided at both ends of the locking rod, a locking pin 123 is inserted through the fourth through hole 122, the locking pin 123 cooperates with the locking seat, the convex platform 121 is used to connect the transmission rod 50, and the locking pin 123 and the convex platform 121 are arranged on the side of the locking rod close to the locking seat. The locking rod of this embodiment can be fixedly connected to the frame part 20 through the rotating shaft 14 and the clamping block 13, or can be slidably connected to the fan part 30. When the locking pin 123 abuts against the locking seat, the doors and windows are locked; when the locking pin 123 is away from the locking seat, the doors and windows are in contact locking. The convex platform 121 is used to connect the transmission rod 50, so that the locking rod moves along with the transmission rod 50 to switch between the locked and unlocked states.

[0081] Specifically, the convex platform 121 is inserted into the transmission rod 50 from the side of the transmission rod 50 away from the locking seat, so that the transmission rod 50 is located between the locking seat and the locking rod. The transmission rod 50 sleeved on the convex platform 121 is used to drive the convex platform 121 and the locking rod to move. The convex platform 121 is inserted into the transmission rod 50 from the side of the transmission rod 50 away from the locking seat, avoiding occupying the surface space of the fan groove of the fan part 30. Compared with the traditional way of inserting the transmission rod 50 from the side of the transmission rod 50 close to the locking seat, it avoids the risk that the locking rod protrudes from the surface of the fan groove and the locking seat collides with the locking rod through the locking rod, so that the locking rod does not need to increase its length to avoid collision, saving the consumables of the locking rod and reducing the production and processing cost of the doors and windows.

[0082] Specifically, a rolling sleeve 15 and an anti-noise block 16 are sleeved on the locking pin 123; the rolling sleeve 15 is sleeved outside the locking pin 123; the anti-noise block 16 is arranged at the end of the locking rod away from the locking seat and is located between the rolling sleeve 15 and the locking rod. The rolling sleeve 15 can reduce friction and wear during the transmission process, and the rolling sleeve 15 and the anti-noise block 16 can effectively reduce noise, improving the transmission efficiency and service life of the locking structure 10.

[0083] Example 6

[0084] This embodiment discloses a locking structure 10, based on Embodiment 1. In this embodiment, the first locking member 11 is a locking rod, and the second locking member 12 is a locking seat. A shaft hole 111 is provided on the locking rod, and the locking rod is fixedly connected to the frame part 20 through the rotating shaft 14 and the clamping block 13; the locking seat is slidably connected to the fan part. When the locking seat and the locking rod abut against each other, the doors and windows are locked; when the locking seat and the locking rod do not contact each other, the doors and windows are unlocked.

[0085] Example 7

[0086] See Figure 1-16 As shown in Figure 1-16 , this embodiment discloses a door and window, which includes a frame part 20 and a sash part 30 that can be opened and closed relative to each other.
