[0022] Understandably, referring to Figures 1 to 4 The door and window lock box of this utility model includes a box body 100 and a transmission mechanism 200. The box body 100 includes a plastic part 110, a square shaft 120, a slider 130, and two housings 140. The two housings 140 are respectively connected to both sides of the plastic part 110. The housings 140 are provided with guide strips 141. The square shaft 120 is rotatably connected to the plastic part 110. The square shaft 120 is provided with a lever 121 protruding radially. The slider 130 has a guide groove 131 and an opening. The guide bar 141 is located in the guide groove 131, the lever 121 is located in the opening groove 132, and the end face of the slider 130 away from the square shaft 120 is provided with a connecting part 133; the transmission mechanism 200 includes a base plate 210 and a slide plate 220. The base plate 210 is fixedly connected to the housing 140, the slide plate 220 is slidably connected to the base plate 210, and the slide plate 220 is fixedly connected to the connecting part 133. The slide plate 220 is fixedly connected with a hanging point rivet 221.

[0023] Two housings 140 are respectively connected to both sides of the plastic part 110. A square shaft 120 is rotatably connected to the plastic part 110. A guide strip 141 is arranged in a guide groove 131, and a lever 121 is arranged in an opening groove 132, so that when the square shaft 120 drives the lever 121 to rotate, it can drive the slider 130 to slide along the length direction of the guide strip 141. A base plate 210 is fixedly connected to the housing 140, and a sliding plate 220 is slidably connected to the base plate 210. By setting the sliding plate 220 and the connecting part 133 to be fixedly connected, the slider 130 can push the sliding plate 220 to move, which can drive the hanging point rivet 221 to move, so that the hanging point rivet 221 can lock or unlock the position of the door or window.

[0024] By cooperating with the guide bar 141 and the guide groove 131, the movement direction of the slider 130 can be limited, making the movement of the slider 130 stable. This can guide the movement direction of the slider 130, reduce the possibility of movement deviation of the slider 130, prevent the movement of the slider 130 from jamming, and thus avoid user misoperation that could cause the slider 130 to deform or break, thereby improving the reliability of the door and window lock box.

[0025] It should be noted that the guide bar 141 is arranged in the guide groove 131 to guide the movement direction of the slider 130 on the housing 140. This can reduce the possibility of the slider 130 shaking or deviating, prevent the slider 130 from jamming, and enable the square shaft 120 to stably push the slider 130 to move smoothly. It can also avoid stress concentration between the lever 121 and the slider 130, thereby preventing the slider 130 from being damaged or failing and improving the reliability of the door and window lock box.

[0026] The guide strip 141 is integrally formed with the housing 140, so that one side of the housing 140 protrudes from the other side to form the guide strip 141. This not only simplifies the processing steps, but also enhances the structural strength of the housing 140, which helps to improve the reliability of the door and window lock box.

[0027] In addition, the hanging point rivet 221 is fixedly connected to the slide plate 220, and the connecting part 133 is fixedly connected to the slide plate 220. The slide plate 220 can be driven to slide on the base plate 210 by the slider 130, thereby driving the hanging point rivet 221 to move so that the hanging point rivet 221 can be locked into or locked into the door and window frame, thereby locking or unlocking the position of the door and window and improving the convenience of use.

[0028] Understandably, referring to Figure 2 and Figure 3 The housing 100 also includes a positioning rivet 150, which is fixedly connected to the two housings 140. The slider 130 has a positioning groove 134, and the positioning rivet 150 passes through the positioning groove 134. The positioning rivet 150 is fixedly connected to the two housings 140, and the slider 130 has a positioning groove 134, which is arranged parallel to the guide bar 141. By setting the positioning rivet 150 in the positioning groove 134, additional constraints are provided for the slider 130, which can more accurately limit the movement direction of the slider 130, further reducing the possibility of movement deviation and wobbling of the slider 130, effectively preventing the slider 130 from jamming, thereby avoiding damage to the slider 130 due to user misoperation and improving reliability.

[0029] In addition, by setting the positioning rivet 150, the slider 130 can be pressed tightly onto the housing 140, so that the guide bar 141 can be stably placed in the guide groove 131, thereby stabilizing the position of the slider 130, avoiding the possibility of the slider 130 becoming loose from the housing 140, and improving reliability.

[0030] Understandably, referring to Figure 2 and Figure 4The base plate 210 has a connection port 211, and the connecting part 133 passes through the connection port 211. The base plate 210 abuts against the end face of the slider 130. The connection port 211 on the base plate 210, with the connecting part 133 passing through it, allows the base plate 210 to abut against the end face of the slider 130, thereby limiting the position of the slider 130, stabilizing its movement, reducing the possibility of positional deviation, and improving movement stability.

[0031] It should be noted that the connecting part 133 extends from the connecting port 211 so that the end face of the slider 130 can abut against the base plate 210. The base plate 210 can limit the position of the slider 130, thereby guiding the movement direction of the slider 130 and reducing the possibility of the slider 130's position shift. Moreover, the base plate 210 can prevent the guide bar 141 from coming out of the guide groove 131, making the position of the slider 130 stable and preventing the slider 130 from getting stuck.

[0032] Specifically, refer to Figure 4 Along the width direction of the box body 100, the connecting part 133 is located in the middle of the box body 100. By setting the connecting part 133 in the middle of the width direction of the box body, not only can the slider 130 be balanced during movement, reducing the possibility of the slider 130 tilting or jamming during movement, but the layout of the box body 100 can also be optimized, making the assembly of the box body 100 easier and improving the structural compactness and assembly convenience.

[0033] It should be noted that the two housings 140 are respectively connected to both sides of the plastic part 110. Both housings 140 are provided with guide strips 141. By setting the connecting part 133 in the middle of the housing width direction, it is convenient to assemble the slider 130, so that the slider 130 can be flexibly installed on either guide strip 141, thereby improving the convenience of assembly.

[0034] Understandably, referring to Figure 2 and Figure 5 The housing 100 also includes a nut 160, which is slidably connected to the plastic part 110. A first stop 161 and a second stop 162 are respectively provided at both ends of the nut 160. The first stop 161 and the second stop 162 are staggered along the circumference of the nut 160, and either the first stop 161 or the second stop 162 can abut against the housing 140. The nut 160 is slidably connected to the plastic part 110 so that the nut 160 can move axially out of the housing 100, allowing the first stop 161 or the second stop 162 to abut against the housing 140. This allows it to adapt to different specifications of doors and windows, meeting the needs of left-opening or right-opening doors and windows, and improving the versatility of the door and window lock box.

[0035] The first stop 161 and the second stop 162 are offset circumferentially from the nut 160. When the nut 160 extends to one side of the housing 100, the first stop 161 can abut against the housing 140; when the nut 160 extends to the other side of the housing 100, the second stop 162 can abut against the housing 140. The cooperation of the first stop 161 and the second stop 162 can limit the movement position of the nut 160 and allow the nut 160 to extend to either side of the housing 100, improving the convenience of installation.

[0036] It should be noted that the box body 100 is located inside the door and window, the square shaft 120 is connected to the handle, and the bolts are inserted through the door and window. The bolts are threaded to the box body 100. In order to improve the connection stability of the bolts, the bolts are often inserted through the stiffening plate of the door and window, and the bolt axis is parallel to the extension direction of the stiffening plate, which weakens the structural strength of the door and window and also makes the installation of the box body 100 inconvenient. By setting the nut 160 to slide and connect the plastic part 110, the cantilever distance of the bolt can be shortened, the positional stability of the bolt can be improved, and there is no need to place the bolts on the stiffening plate of the door and window. This not only facilitates the installation but also improves the connection strength and enhances the usability of the door and window lock box.

[0037] Specifically, refer to Figure 2 The transmission mechanism 200 also includes a connecting component 230, which includes a snap rivet 231 and a snap 232. The snap rivet 231 passes through the base plate 210 and the snap 232, and the snap 232 is used to engage with the door or window. The snap 232 is fastened to the door or window, and the snap rivet 231 passes through the base plate 210 and the snap 232. The snap rivet 231 can press the snap 232 tightly onto the door or window, so that the transmission mechanism 200 can be fixed to the door or window. This increases the number of installation points for the door and window lock box, reduces the stress on the bolts, and improves the connection stability of the door and window lock box.

[0038] It should be noted that the doors and windows are provided with mounting grooves. By installing the buckle 232 in the mounting groove, the buckle 232 can be pressed tightly against the wall of the mounting groove by the buckle rivet 231, thereby improving the stability of the connection.

[0039] Among them, the snap rivet 231 can be a rivet, bolt, screw, etc., which will not be described in detail here.

[0040] Understandably, referring to Figure 2There are two slide plates 220. One slide plate 220 is fixedly connected to the connecting part 133. The slide plate 220 is provided with a rack part 222. The base plate 210 is rotatably connected to a gear 212, and the gear 212 meshes with the rack part 222. Both slide plates 220 are provided with rack parts 222, and the gear 212 is rotatably connected to the base plate 210. By providing two rack parts 222 that mesh with the gear 212, when the connecting part 133 pushes one slide plate 220 to move, the rack part 222 can drive the gear 212 to rotate. This allows the gear 212 to push the rack part 222 on the other slide plate 220 to move. This allows the two hanging point rivets 221 to move away from or towards each other, reducing the force on a single hanging point rivet 221, reducing the possibility of stress concentration, and improving reliability.

[0041] Specifically, refer to Figure 2 The base plate 210 has limit grooves 213 at both ends, and the hanging point rivets 221 are slidably connected in the limit grooves 213. The limit grooves 213 at both ends of the base plate 210, and the two hanging point rivets 221 are respectively arranged in the two limit grooves 213. The position of the hanging point rivets 221 can be limited by the limit grooves 213, effectively preventing the hanging point rivets 221 from deviating or shaking during the movement, improving the stability and accuracy of the movement of the hanging point rivets 221, and thus ensuring the accuracy of the door and window locking and unlocking operations.

[0042] Understandably, referring to Figure 2 and Figure 3 The lever 121 has a protruding abutment portion 122, which is arc-shaped and abuts against the side wall of the opening groove 132. The abutment portion 122 is positioned on the lever 121 and located within the opening groove 132. By designing the abutment portion 122 to be arc-shaped, a smoother contact with the side wall of the opening groove 132 is achieved, effectively reducing friction during the abutment process and decreasing wear caused by frequent friction between the lever 121 and the slider 130, thus extending the service life of both the lever 121 and the slider 130. Simultaneously, the arc-shaped abutment portion 122 can disperse stress, preventing stress concentration that could damage components, improving the stability and reliability of the door and window lock box, making locking and unlocking operations smoother, reducing the possibility of jamming, and enhancing the user experience.

[0043] Understandably, referring to Figure 1 and Figure 3 The square shaft 120 has a recess 123, which is rectangular in shape. The rectangular shape of the recess 123 facilitates handle connection, prevents slippage of the handle within the recess 123, and avoids transmission errors caused by loosening, thus ensuring more precise and reliable locking and unlocking operations for the door and window lock box.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
