Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to an anti-theft lock point transmission housing and a door and window structure. Background Art

[0002] When locking a traditional transmission housing, doors and windows are primarily secured by upper and lower locking points on either side and a middle locking point on the other side. As door and window sashes increase in height, additional locking points are often required to maintain structural stability and prevent vertical deformation of the profile. This approach not only increases the complexity of aluminum rod cutting, raising material costs and processing difficulty, but also prolongs installation time and reduces construction efficiency. Furthermore, due to the inevitable dimensional errors in window profiles and rubber strips during the production process, insufficient locking force in a multi-point locking system will weaken the seal between the profile and rubber strip, compromising the airtightness and watertightness of the entire window, reducing the energy efficiency and service life of the doors and windows.

[0003] For inward-opening and inward-tilting doors and windows, the transmission housing usually adopts a one-way transmission design, with a limited transmission distance (such as 36mm), and the transmission path needs to be precisely controlled to avoid interference. When the initial position is 0, it moves upward 18mm to achieve locking, and moves downward 18mm to achieve the inward tilt function. This design faces huge challenges when adding anti-theft lock points: on the one hand, it is necessary to ensure that the up and down movement of the transmission housing will not interfere with the added anti-theft lock points within the limited frame and sash spacing (such as 11.5mm); on the other hand, the transmission housing itself is mostly designed as a protruding notch surface, and adding anti-theft lock points directly on it can easily cause spatial conflicts, affecting the smoothness of transmission and opening and closing.

[0004] What is even more complicated is that the distance from the bottom of the groove to the surface of the groove opening is limited (such as 4.5mm). The existing inward-opening and inward-tilting doors and windows need to consider the size requirements of the installation opening of the groove bottom shell, and the transmission distance, the distance from the bottom of the groove to the surface of the groove opening, and the frame and sash spacing are all fixed values. Therefore, it is impossible to reasonably arrange the anti-theft lock points on the transmission shell and ensure that it can achieve smooth transmission without interference in different states.

[0060] See also Figure 1-3 This embodiment provides an anti-theft lock point transmission housing for achieving locking with a fixing member 1 mounted on a frame, comprising: a transmission assembly 2, the transmission assembly 2 being configured to be in transmission connection with a handle (not shown) to convert the rotational motion of the handle into linear motion of the transmission assembly 2;

[0061] The transmission assembly 2 is provided with an anti-pry locking portion 3, which is used to lock or unlock with an anti-pry locking portion 4 on the fixing member 1; and / or, the transmission assembly 2 is provided with an anti-pry locking portion 4, which is used to lock or unlock with the anti-pry locking portion 3 on the fixing member 1;

[0062] When the handle is rotated, the transmission assembly 2 moves linearly to engage or disengage the anti-theft locking member 4 from the anti-theft locking portion 3 .

[0063] In this embodiment, an anti-pry locking member 4 and an anti-pry locking portion 3 are provided between the transmission assembly 2 and the fixing member 1, so that the transmission housing can increase anti-pry locking points in a limited space, thereby improving the safety and installation efficiency of the window and reducing the processing difficulty and cost of the entire window.

[0064] Example 1:

[0065] See also Figure 1-3 This embodiment provides an anti-theft lock point transmission housing, including: a transmission assembly 2, which is used to be connected to the handle transmission to convert the rotational motion of the handle into a linear movement of the transmission assembly 2; an anti-theft locking part 3 is provided on the transmission assembly 2, and an anti-theft locking part 4 is provided on the fixing part 1.

[0066] Specifically, the transmission assembly 2 includes a rotating wheel 21 and a transmission bar 22. The rotating wheel 21 is connected to the handle transmission. A rack 221 (such as Figure 4 As shown), the rotating wheel 21 is engaged with the rack 221, and the anti-theft locking member 4 or the anti-theft locking portion 3 is arranged on the other side of the transmission bar 22.

[0067] The drive wheel 21 has a high transmission efficiency, which can effectively convert the rotational motion of the handle into the linear motion of the transmission bar 22. This efficient energy conversion reduces energy loss, makes the operation smoother, and also prolongs the service life of the system.

[0068] In this embodiment, please refer to Figure 1 The transmission housing also includes: a housing 5, the housing 5 includes a first housing 51 and a second housing 52, the first housing 51 and the second housing 52 are connected and an accommodating chamber is provided between the first housing 51 and the second housing 52, the transmission assembly 2 is provided in the accommodating chamber, the first housing 51 and the second housing 52 are both provided with a sliding groove 53 for limiting the left and right swing of the transmission bar 22, the transmission bar 22 is slidably installed in the sliding groove 53, and the middle part of the first housing 51 and the second housing 52 is provided with a mounting hole 54 for fixing the rotating wheel 21. The first housing 51 and the second housing 52 only need to set an opening 55 for the anti-theft lock 4 to enter and exit on one side to meet the entry and exit of the locking point (i.e., the anti-theft lock 4), the opening 55 can be set smaller, the strength is set better, the appearance is more beautiful, and the transmission bar 22 is shorter.

[0069] In this embodiment, please refer to Figure 2-5 The anti-pry locking member 4 includes: a locking portion 41 and an anti-pry portion 42. The locking portion 41 is connected to the anti-pry portion 42. The anti-pry locking portion 3 is provided with a locking groove 31 for limiting the movement of the locking portion 41 in the first direction and a limiting end 32 for limiting the movement of the anti-pry portion 42 in the second direction.

[0070] The combined design of the locking portion 41 and the anti-pry portion 42 on the anti-pry lock 4 integrates the locking portion 41 and the anti-pry portion 42 into one body, simplifying the structure of the anti-pry lock 4 and reducing its processing and manufacturing costs. It also significantly reduces the size of the anti-pry lock 4, making it more adaptable to situations where space in a transmission case is limited. Furthermore, the arrangement of the locking portion 41 and the locking groove 31 ensures that when the locking portion 41 moves into the locking groove 31, the locking groove 31 restricts movement of the locking portion 41 in a first direction, thereby achieving a locking effect. The design of the anti-pry portion 42 and the limiting end 32 ensures that when the anti-pry portion 42 moves into the limiting end 32, the limiting end 32 restricts movement of the locking portion 41 in a second direction, thereby achieving a locking effect.

[0071] Furthermore, the fixing member 1 further includes a mounting portion 11, one end of the locking portion 41 is connected to the mounting portion 11, and the other end of the locking portion 41 is connected to the anti-pry portion 42. The mounting portion 11 is fixed to the frame to secure the entire fixing member 1 to the frame, ensuring that the fixing member 1 remains stationary.

[0072] Specifically, the mounting portion 11 is shaped like a plate, the locking portion 41 is shaped like a cylinder, the anti-pry portion 42 is shaped like a T-shaped structure, the limiting end 32 is provided with two protrusions, and there is a gap between the two protrusions. The width of the gap is greater than or equal to the diameter of the locking portion 41, so that the locking portion 41 can slide in the gap. At the same time, the width of the gap is smaller than the diameter of the top of the anti-pry portion 42, so that when the locking portion 41 slides into the gap, the anti-pry portion 42 cannot move in the second direction. Since the anti-pry portion 42 of this embodiment is installed on the locking portion 41, the limiting end 32 is installed in the locking groove 31.

[0073] It should be noted that the moving direction of the transmission bar is set to the up-down direction, the first direction is the left-right direction, and the second direction is the front-back direction.

[0074] In this embodiment, the locking portion 41 and the anti-pry portion 42 are connected to form a T-shaped structure, and the limiting end 32 is installed on the locking groove 31. The limiting end 32 is installed on the locking groove 31, so that the limiting end 32 and the locking groove 31 are integrated, simplifying the structural design and processing of the anti-pry locking portion 3.

[0075] In this embodiment, a sliding groove 222 is provided on the other side of the transmission bar 22 (eg Figure 5 As shown), the slide groove 222 and the rack 221 are both perpendicular to the center line N of the moving direction of the transmission bar 22 (as shown Figure 5 As shown in the figure, the anti-theft locking parts 3 are symmetrically arranged, and two anti-theft locking parts 3 are respectively arranged on both sides of the slide groove 222. When the window sash is closed, the anti-theft locking part 4 is slidably installed in the slide groove 222.

[0076] The slide groove 222 and the rack 221 are both symmetrically arranged about the central vertical line N of the moving direction of the transmission bar 22, so that the entire transmission bar 22 has a vertically symmetrical structure. When assembling the transmission bar 22, there is no need to distinguish the assembly direction of the transmission bar 22, which improves the installation efficiency of the transmission housing.

[0077] In this embodiment, please refer to Figure 1 and Figure 6 The transmission housing includes: a countersunk screw 6, a hollow hexagonal screw 7 and a nut block 8. The hollow hexagonal screw 7 passes through the housing 5 and the profile 9 in sequence and is threadedly connected to the nut block 8. By tightening the hollow hexagonal screw 7, the nut block 8 is tightly attached to the inner upper wall of the profile 9, and the housing 5 and the nut block 8 clamp the profile 9. Finally, the countersunk screw 6 is passed through the middle of the hollow hexagonal screw 7 to penetrate the profile 9, and the transmission housing can be fixed on the profile 9. Since the nut thickness of the hollow hexagonal screw 7 is 1 mm, enough space can be left for the transmission bar 22 to slide.

[0078] In this embodiment, the transmission housing includes an anti-pull block 10 (such as Figure 1As shown), the anti-pull oblique block 10 is set on the shell 5, and the anti-pull oblique block 10 can prevent the shell 5 from being tilted by the force when the handle is installed.

[0079] In this embodiment, the cover 23 (such as Figure 1 As shown), the covering member 23 is installed on the transmission bar 22 to cover the anti-theft locking portion 3 exposed on the transmission bar 22, thereby improving the appearance of the transmission housing.

[0080] The working principle of the transmission housing of this embodiment is as follows: since the fixing member 1 on the frame is fixed, when the sash is opened horizontally, the transmission bar 22 is in the middle position, and the anti-theft locking portion 3 on the transmission bar 22 does not interfere with the anti-theft locking member 4, so the sash can be opened horizontally normally; when locking, the handle drives the rotating wheel 21 to rotate, and the rotating wheel 21 engages with the transmission bar 22, converting the rotation of the rotating wheel 21 into an up and down linear motion. When the handle rotates downward, the rotating wheel 21 also rotates downward, and the transmission bar 22 moves upward, causing the anti-theft locking portion 3 on the transmission bar 22 to move upward. When the anti-theft locking member 4 enters the anti-theft locking portion 3 on the transmission bar 22, they cooperate with each other to achieve the functions of locking and anti-theft (such as Figure 7 When tilting inward, the handle is rotated upward. The rotating wheel 21 rotates upward, and the transmission bar 22 moves downward. Because the opening of the transmission bar 22 is large enough, the anti-theft locking part 3 and the anti-theft locking member 4 do not interfere with each other, so the door can be tilted out smoothly.

[0081] Example 2:

[0082] In this embodiment, the anti-pry locking member 4 is provided on the transmission bar 22 , and the anti-pry locking portion 3 is provided on the fixing member 1 . The anti-pry locking member 4 is used to lock or unlock with an anti-pry locking portion 3 on the fixing member 1 .

[0083] Specifically, there is one anti-pry locking part 3, which is arranged on the fixing part 1, and the anti-pry locking part 4 is arranged on the transmission bar 22. The anti-pry locking part 4 and the rack 221 are both asymmetrically arranged about the central vertical line N of the moving direction of the transmission bar 22.

[0084] The anti-pry lock member 4 and the rack 221 are both asymmetrically arranged with respect to the central perpendicular line N of the moving direction of the transmission bar 22, so that the excess portion of the transmission bar 22 can be used to rivet the anti-pry lock member 4. As a result, the length of the groove bottom mounting opening of this embodiment is also longer than that of the embodiment 1, and the moving range of the transmission bar 22 is wider.

[0085] Furthermore, both the first shell 51 and the second shell 52 are provided with an opening 55 for the anti-theft locking member 4 to enter and exit. Figure 8 As shown), anti-pull oblique blocks 10 can also be installed on the first shell 51 and the second shell 52.

[0086] This arrangement makes the width of the groove bottom installation opening 55 wider than that of Example 1. Handles can be used on both the first shell 51 and the second shell 52. When installing the other side, there is no need to install the entire shell 5 upside down. It is only necessary to install the anti-pull bevel block 10 to the other end of the shell 5, which is simple and convenient.

[0087] In this embodiment, the housing 5 is fixed with pan head screws 56 (such as Figure 8 As shown) and fixed with the nut block 8, specifically, the transmission housing includes: a pan head screw 56 and a nut block 8, the pan head screw 56 passes through the housing 5 and the profile 9 in sequence and is threadedly connected with the nut block 8.

[0088] The combination of the pan head screw 56 and the nut block 8 can provide a stable and reliable fastening effect. The nut block 8, as an auxiliary fixing member 1, can increase the force-bearing area of ​​the fastening point and disperse the pressure, thereby improving the stability and durability of the fastening.

[0089] The working principle of the transmission housing of this embodiment is as follows: since the fixing member 1 on the frame is fixed, when the sash is opened horizontally, the transmission bar 22 is in the middle position, and the anti-theft locking member 4 on the transmission bar 22 does not interfere with the anti-theft locking portion 3 on the fixing member 1, and the sash can be opened horizontally normally (such as Figure 10 When locking, the handle drives the rotating wheel 21 to rotate, and the rotating wheel 21 engages with the transmission bar 22, converting the rotation of the rotating wheel 21 into an up-and-down linear motion. When the handle rotates downward, the rotating wheel 21 also rotates downward, and the transmission bar 22 moves upward, causing the anti-theft locking member 4 on the transmission bar 22 to move upward. When the anti-theft locking member 4 enters the anti-theft locking portion 3 on the fixing member 1, they cooperate with each other to achieve the functions of locking and anti-theft (as shown in FIG. Figure 10 b); when tilting inward, the handle is rotated upward. The wheel 21 rotates upward, and the transmission bar 22 moves downward. Because the opening of the transmission bar 22 is large enough, the anti-theft locking part 3 and the anti-theft locking member 4 do not interfere with each other, so the door can be tilted out smoothly (as shown in FIG. Figure 10 c).

[0090] Example 3:

[0091] See also Figure 11 In this embodiment, the anti-pry locking portion 3 is provided with one, and the anti-pry locking portion 3 is provided on the fixing member 1, and the anti-pry locking member 4 is provided on the transmission bar 22. The anti-pry locking member 4 and the rack 221 are both asymmetrically arranged about the center line M of the moving direction of the transmission bar 22. Specifically, the anti-pry locking portion 3 and the anti-pry locking member 4 are offset toward the handle.

[0092] In order to ensure that the anti-pry locking member 4 avoids the rack 221 during riveting, the structural design of this embodiment is different from that of embodiment 2. Specifically, the position of the anti-pry locking member 4 of this embodiment relative to the transmission bar 22 is different from that of the anti-pry locking member 4 of embodiment 2. The anti-pry locking member 4 of this embodiment is asymmetrically arranged with respect to the center line M of the moving direction of the transmission bar 22, and is symmetrically arranged with respect to the center perpendicular line N of the moving direction of the transmission bar 22, while the anti-pry locking member 4 of embodiment 2 is asymmetrically arranged with respect to the center perpendicular line N of the moving direction of the transmission bar 22, and is symmetrically arranged with respect to the center line M of the moving direction of the transmission bar 22. Therefore, the transmission bar 22 of this embodiment is shorter than that of embodiment 2. Therefore, the overall length of the transmission housing of this embodiment is shorter than that of embodiment 2, and it is more beautiful. At the same time, it is not as bulky as embodiment 2.

[0093] In this embodiment, both the first shell 51 and the second shell 52 are provided with openings 55 for the anti-theft locking member 4 to enter and exit. When the other shell 5 is installed, it is only necessary to turn the transmission housing upside down, which is simple and convenient.

[0094] In this embodiment, the housing 5 is fixed by using pan head screws 56 and nut blocks 8. Specifically, the transmission housing includes: pan head screws 56 and nut blocks 8. The pan head screws 56 pass through the housing 5 and the profile 9 in sequence and are threadedly connected to the nut block 8.

[0095] The combination of the pan head screw 56 and the nut block 8 can provide a stable and reliable fastening effect. The nut block 8, as an auxiliary fixing member 1, can increase the force-bearing area of ​​the fastening point and disperse the pressure, thereby improving the stability and durability of the fastening.

[0096] The working principle of the transmission housing of this embodiment is as follows: since the fixing member 1 on the frame is fixed, when the sash is opened horizontally, the transmission bar 22 is in the middle position, and the anti-theft locking member 4 on the transmission bar 22 does not interfere with the anti-theft locking portion 3 on the fixing member 1, and the sash can be opened horizontally normally (such as Figure 12 When locking, the handle drives the rotating wheel 21 to rotate, and the rotating wheel 21 engages with the transmission bar 22, converting the rotation of the rotating wheel 21 into an up-and-down linear motion. When the handle rotates downward, the rotating wheel 21 also rotates downward, and the transmission bar 22 moves upward, causing the anti-theft locking member 4 on the transmission bar 22 to move upward. When the anti-theft locking member 4 enters the anti-theft locking portion 3 on the fixing member 1, they cooperate with each other to achieve the functions of locking and anti-theft (as shown in FIG. Figure 12 b); when tilting inward, the handle is rotated upward. The wheel 21 rotates upward, and the transmission bar 22 moves downward. Because the opening of the transmission bar 22 is large enough, the anti-theft locking part 3 and the anti-theft locking member 4 do not interfere with each other, so the door can be tilted out smoothly (as shown in FIG. Figure 12 c).

[0097] Example 4:

[0098] See also Figure 13-15 In this embodiment, the anti-pry structure and the locking structure are separate. Specifically, the anti-pry locking member 4 is provided with a lock member 43 and a lock groove 44 for limiting the movement of the lock member 43 in the first direction, and the other of the lock member 43 and the lock groove 44 is provided on the anti-pry locking portion 3. The anti-pry locking member 4 is provided with an anti-pry member 45 and a limiting groove 46 for limiting the movement of the anti-pry member 45 in the second direction, and the other of the anti-pry member 45 and the limiting groove 46 is provided on the anti-pry locking portion 3.

[0099] The separate design of the anti-pry and locking mechanisms ensures that even if one is damaged, the other can still function, significantly reducing the maintenance and replacement costs of the transmission case. Furthermore, users can choose different combinations of anti-pry and locking mechanisms to suit their specific safety requirements, depending on their needs and scenarios.

[0100] The locking groove 44 and the limiting groove 46 are provided on the transmission bar 22 (as shown in FIG. Figure 14 As shown in FIG, the locking member 43 and the anti-pry member 45 are provided on the fixing member 1 for detailed description.

[0101] In this embodiment, the housing 5 is fixed by a hollow hexagonal screw 7 and a nut block 8 (eg Figure 16 As shown), specifically, the transmission housing includes: a hollow hexagonal screw 7 and a nut block 8. The hollow hexagonal screw 7 passes through the housing 5 and the profile 9 in sequence and is threadedly connected to the nut block 8. Different from the clamping of the nut block 8 in Example 1, the hollow hexagonal screw 7 and the nut block 8 in this embodiment are arranged inside the housing 5, so the size of the groove bottom mounting opening in this embodiment is also longer than that in Example 1. The clamping surface of the nut block 8 in the corresponding housing 5 is on the inner cavity wall 57 of the fan slot. The clamping surface of Example 1 is the upper wall of the slot, and the hollow hexagonal screw 7 must be screwed into the housing 5 before the housing 5 is riveted. In Example 1, the screw is screwed in after the housing 5 is riveted. The shape of the nut block 8 is also different. The nut block 8 in Example 1 is a whole plane, while the nut block 8 in this embodiment is a convex hull with a height of 0.6 mm on both sides. When the wall thickness of the inner cavity wall 57 of the fan slot is different, the thickness needs to be offset so as to fit tightly against the inner cavity wall 57 of the fan slot.

[0102] It should be noted that the anti-pry structure and the locking structure are not limited to a separate structural form, and this embodiment is not intended to limit it to a single form. The lock groove 44 and the lock member 43, as well as the limiting groove 46 and the anti-pry member 45 in the separate structure can also achieve a separate anti-pry locking function through different arrangements and combinations. For example, the lock groove 44 and the anti-pry member 45 are provided on the fixing member 1, and the lock member 43 and the limiting groove 46 are provided on the transmission bar 22 (e.g. Figure 17Or the lock member 43 and the anti-pry member 45 are arranged on the fixing member 1, and the lock slot 44 and the limiting slot 46 are arranged on the transmission bar 22 (as shown). Figure 18 Alternatively, the lock member 43 and the lock slot 44 are on the fixing member 1, the limit slot 46 and the anti-pry member 45 are on the transmission bar 22, and the anti-pry member 45 is provided with one (as shown in FIG. Figure 19 Alternatively, the lock member 43 and the lock slot 44 are on the fixing member 1, the limit slot 46 and the anti-pry member 45 are on the transmission bar 22, and the anti-pry member 45 is provided with two (as shown in FIG. Figure 20 Alternatively, the lock member 43 and the anti-pry member 45 are arranged on the fixing member 1, and the lock slot 44 and the limit slot 46 are arranged on the transmission bar 22 (as shown). Figure 21 shown).

[0103] It should be noted that Figure 17-21 a in the figure represents a structural schematic diagram of the transmission housing in a locked state, b represents a structural schematic diagram of the transmission housing in a flatly opened state, and c represents a structural schematic diagram of the transmission housing in an inwardly tilted state.

[0104] The working principle of the transmission housing of this embodiment is as follows: since the fixing member 1 on the frame is fixed, when the sash is opened horizontally, the transmission bar 22 is in the middle position, the locking groove 44 and the locking member 43, as well as the limiting groove 46 and the anti-pry member 45, are not interfered with each other, and the sash can be opened horizontally normally (such as Figure 22 When locking, the handle drives the rotating wheel 21 to rotate, and the rotating wheel 21 engages with the transmission bar 22, converting the rotation of the rotating wheel 21 into an up-and-down linear motion. The handle rotates downward, the rotating wheel 21 also rotates downward, and the transmission bar 22 moves upward, so that the lock groove 44 and the limit groove 46 on the transmission bar 22 move upward, so that the lock piece 43 and the anti-pry piece 45 on the frame can enter the lock groove 44 and the limit groove 46 respectively, and cooperate with each other to achieve the functions of locking and anti-prying (as shown in FIG. Figure 22 b); when tilting inward, the handle is rotated upward, the wheel 21 rotates upward, and the transmission bar 22 moves downward. Because the distance between the lock groove 44 and the limit groove 46 is long enough, the lock groove 44 and the lock member 43, as well as the limit groove 46 and the anti-pry member 45, do not interfere with each other, so the door can be tilted out smoothly (as shown in FIG. Figure 22 c).

[0105] Example 5:

[0106] See also Figure 23 In this embodiment, the anti-pry structure is replaced by a covering member 23. Specifically, the transmission assembly 2 includes: a covering member 23, the covering member 23 is installed on the other side of the transmission bar 22, the limiting end 32 is installed on the covering member 23, and the locking groove 31 is set on the transmission bar 22.

[0107] The structure of the anti-pry lock member 4 of this embodiment is the same as that of the anti-pry lock member 4 of Example 1. The limiting end 32 and the locking groove 31 are respectively installed on different components. When one structure is damaged, the other structure can still perform its own function, which greatly reduces the maintenance and replacement costs of the transmission housing.

[0108] In this embodiment, the cover 23 is retractable. When the gap between the frame and the sash is too large, the anti-pry locking member 4 may not be able to enter the anti-pry locking portion 3, and cannot play the role of locking and anti-prying. The stainless steel sheet can be stretched to reduce the gap between the anti-pry locking member 4 and the cover 23, so that the anti-pry locking member 4 can enter the cover 23, playing the role of locking and anti-prying.

[0109] For details, please refer to Figure 23-25 The transmission assembly 2 also includes: an adjusting member 24 and a clamping member 25. An accommodating portion 223 is provided on the transmission bar 22. One end of the adjusting member 24 is connected to the covering member 23, and the other end of the adjusting member 24 is connected to the clamping member 25. The clamping member 25 is installed in the accommodating portion 223 and abuts against the inner wall of the accommodating portion 223.

[0110] When the gap between the anti-theft locking member 4 and the covering member 23 needs to be adjusted, the covering member 23 is pulled to move. When the covering member 23 moves, the adjusting member 24 is driven to move, and the movement of the adjusting member 24 is driven to move the holding member 25. During the movement, the holding member 25 is always in contact with the inner wall of the accommodating portion 223. When the covering member 23 moves to a suitable position, the holding member 25 is in contact with the inner wall of the accommodating portion 223, so that the position of the covering member 23 can be fixed.

[0111] Furthermore, a plurality of adjusting members 24 and a plurality of holding members 25 are provided. The provision of a plurality of adjusting members 24 and holding members 25 can enhance the fixing effect of the covering member 23 after being pulled.

[0112] The holding member 25 may be a retaining spring or other elastic member that can always abut against the inner wall of the accommodating portion 223 and can be fixed to the adjusting member 24 .

[0113] It should be noted that the telescopic structure is not limited. This embodiment only lists one form and is not intended to limit it to one form. For example, a structural design with multiple adjustment holes, springs and balls can also be adopted. Specifically, by arranging the spring and the ball in the adjustment member 24 and providing multiple adjustment holes on the inner wall of the accommodating portion 223, the gap between the anti-theft locking member 4 and the covering member 23 can be adjusted by clamping the ball in different adjustment holes.

[0114] To ensure the anti-pry strength of the covering member 23, the thickness of the covering member 23 in this embodiment is greater than the thickness of the covering member 23 in Example 1, and the opening size of the covering member 23 is smaller than the opening size of the covering member 23 in Example 1 so that the anti-pry locking member 4 can be limited in the second direction, thereby realizing the anti-pry function.

[0115] The working principle of the transmission housing of this embodiment is as follows: since the anti-pry locking member 4 on the fixing member 1 is fixed and the anti-pry locking member 4 is not installed in the center, when the door is opened horizontally, the transmission bar 22 is in the middle position, and the anti-pry locking portion 3 on the transmission bar 22 (referring to the structure composed of the limit end 32 and the locking groove 31 on the transmission bar 22) has no interference with the anti-pry locking member 4, so the door can be opened horizontally normally; when locking, the handle drives the rotating wheel 21 to rotate, and the rotating wheel 21 engages with the transmission bar 22, converting the rotation of the rotating wheel 21 into an up and down linear motion. When the handle is rotated downward, the rotating wheel 21 also rotates downward, and the transmission bar 22 moves upward, causing the anti-pry locking portion 3 on the transmission bar 22 to move upward. When the anti-pry locking member 4 enters the anti-pry locking portion 3 on the transmission bar 22, they cooperate with each other to perform the functions of locking and anti-prying; when tilting inward, the handle is rotated upward. When the rotating wheel 21 rotates upward, the transmission bar 22 moves downward. Since the opening of the transmission bar 22 is large enough, the anti-theft locking piece 4 does not interfere with the anti-theft locking portion 3, and the bag can be folded out smoothly.

[0116] This embodiment also provides a door and window structure, including: the anti-theft lock point transmission housing of the above embodiment.
