Description

Technical Field

[0001] This application relates to the technical field of drawer locking components, and more particularly to a partition locking device. Background Technology

[0002] In modern home, office, and industrial settings, drawers serve as a core component for storage, finding widespread application in wardrobes, desks, industrial workbenches, and other areas. Current drawer slide assemblies typically consist of a slide base fixed to the cabinet and a bottom slide connecting to the drawer body. Traditional drawer locks lack a corresponding locking mechanism, which means that a stable lock cannot be guaranteed after the drawer is pulled out. This can cause the drawer to move during the process of taking out and putting in items, thus affecting the quick operation of taking out and putting in items. Moreover, the drawer may become loose or shift during use, making it impossible to guarantee the neatness of the stored items. Utility Model Content

[0003] To improve the stability of drawers when taking items out and putting them in, this application provides a partition locking device.

[0004] The partition locking device provided in this application adopts the following technical solution: A partition locking device includes a drawer body and positioning slides disposed on both sides of the lower end of the drawer body. The positioning slides include a support body and a slide rail seat. The slide rail seat is fixedly installed on the upper end face of the support body. Bottom slide rails that slide in cooperation with the slide rail seat are installed on both sides of the lower end face of the drawer body. The bottom slide rails are fixedly connected to the drawer body. A linkage seat is also installed on the rear end face of the drawer body. The linkage seat includes a positioning seat and a linkage shaft. The positioning seats are configured in two sets, and the two sets of positioning seats are fixedly installed on both sides of the rear end face of the drawer body. Both ends of the linkage shaft are rotatably mounted on the positioning seats, and both ends of the linkage shaft are also fixedly mounted with snap-fit ​​parts. The tail of the snap-fit ​​part is connected to the positioning seat through a tension spring. Adjustable latches corresponding to the snap-fit ​​parts are also installed on the support body.

[0005] By adopting the above technical solution, two sets of positioning slides are fixedly installed on the inner wall of the cabinet. These two sets of positioning slides can then assist in supporting the drawer body, ensuring that the drawer body can slide stably on the support body during use. The cooperation between the slide rail base and the bottom slide rail provides a smooth track for the drawer to be pulled out, reduces frictional resistance, and improves the convenience of using the drawer. By installing a linkage seat on the rear end of the drawer body, and designing the linkage seat as a structure that cooperates with the linkage shaft, the linkage shaft can be positioned and installed using two sets of positioning seats, facilitating stable rotation of the linkage shaft. Simultaneously, by fixing snap-fit ​​pieces to both ends of the linkage shaft, the snap-fit ​​pieces at both ends can be rotated synchronously, allowing for easy and convenient operation by operating one end simultaneously. Furthermore, by installing adjustable latches corresponding to the snap-fit ​​pieces on the support body, the snap-fit ​​pieces and adjustable latches can be locked together under the action of a tension spring when no external force is applied. This ensures automatic locking when the drawer body is pulled out, guaranteeing the stability of the drawer body during use. To unlock, the user simply needs to manually lift the snap-fit ​​pieces to return the drawer body to its original position.

[0006] Optionally, the support body includes a base plate and a side plate. The side plate is vertically installed on one side of the base plate, and a bracket for mounting the slide rail is provided on the other side of the base plate. Both the side plate and the bracket are fixedly connected to the base plate.

[0007] By adopting the above technical solution, and designing the main body of the support as a structure in which the bottom plate and side plate fit together, it is ensured that the side plate can be fixed to the cabinet during use, and the bottom plate is designed for easy and stable installation of adjustable latches. Brackets are fixedly installed on the bottom plate, facilitating the support of the two sets of brackets for the slide rail base. This allows for the stable installation of the bottom slide rail on the lower end of the drawer body, enabling the drawer body to be pulled out and pulled out.

[0008] Optionally, the base plate is provided with a guide groove for installing an adjustable locking block, and the side plate is provided with several sets of connecting through holes evenly distributed. An anti-slip plate is fixedly installed at the head of the slide rail, and a limiting groove corresponding to the anti-slip plate is provided in the bottom slide rail.

[0009] By adopting the above technical solution, a guide groove is provided on the bottom plate, which allows the adjustable locking block to be installed in the guide groove and then slidably adjusted to change its position. This makes it easy to flexibly determine the corresponding installation position according to the drawer's usage requirements during installation. The connecting through holes on the side plate can be used to connect or fix with other components such as the cabinet, increasing the versatility of the device. The anti-slip plate and the limiting groove work together to prevent the drawer body from sliding off the slide rail, increasing the safety of the drawer.

[0010] Optionally, the positioning seat includes a main housing and an extension plate, wherein the extension plate is installed on one side of the main housing and is integrally formed with the main housing.

[0011] By adopting the above technical solution, the positioning seat is designed as a structure in which the main housing and the outer plate cooperate. During use, the main housing ensures that the linkage shaft can be stably rotated and installed, while the outer plate facilitates the positioning and installation of other components.

[0012] Optionally, the extension plate is provided with an arc-shaped groove, and a positioning bracket for mounting a tension spring is also provided on the side of the extension plate. The positioning bracket is integrally formed with the extension plate.

[0013] By adopting the above technical solution and creating an arc-shaped groove on the outer extension plate, the stability of the snap-fit ​​component during the flipping process is increased, thus improving the stability of the snap-fit ​​component in use. Simultaneously, a positioning mounting plate is provided on the side of the outer extension plate to facilitate the stable and fixed installation of the tension spring head.

[0014] Optionally, the snap-fit ​​component includes a flipping part and a triangular snap-fit ​​block. The flipping part is sleeved and fixed on the head of the linkage shaft. The triangular snap-fit ​​block is integrally formed on the lower end face of the flipping part. The tail of the flipping part is provided with an arc-shaped tail plate corresponding to the arc-shaped groove. The arc-shaped tail plate is integrally formed with the flipping part.

[0015] By adopting the above technical solution, the integrated molding design of the flipping part and the triangular locking block of the snap-fit ​​component results in a simple structure with high strength. The cooperation between the triangular locking block and the adjustable locking block enables effective snap-fitting and locking. The corresponding setting of the arc-shaped tail plate and the arc-shaped groove further limits the rotation range of the snap-fit ​​component and improves the stability of the locking.

[0016] Optionally, the adjustable locking block includes a sliding block and an inclined block corresponding to the triangular locking block. The sliding block is slidably installed in the guide groove, and the inclined block is fixedly installed on the upper end face of the sliding block.

[0017] By adopting the above technical solution, the adjustable locking block's slide block can slide in the guide groove and can be locked in different positions by tightening screws. The cooperation between the inclined block and the triangular locking block makes the locking and unlocking process smoother.

[0018] Optionally, the lower end of the slide block is fitted with a locking screw that locks with the base plate, and the lower end surface of the base plate is provided with positioning scales that cooperate with the slide block.

[0019] By adopting the above technical solution and setting the positioning scale, users can accurately adjust the position of the adjustable blocks during installation to adapt to different usage needs. After the position is determined, it can be fixed by locking screws. At the same time, it is convenient for the adjustable blocks at both ends to be installed simultaneously, avoiding deviations at both ends that may affect the overall use.

[0020] In summary, this application includes at least one of the following beneficial technical effects: The partition locking device of this application has a simple overall structure, reasonable design of each component, and is easy to install and disassemble, reducing production costs and maintenance difficulty. Through the cooperation of the snap-fit ​​parts and adjustable blocks, as well as the action of the tension spring, reliable locking of the drawer can be achieved, effectively preventing the drawer from loosening or shifting during use, ensuring the neatness of stored items. The adjustability of the adjustable blocks allows the device to adapt to different drawer sizes and usage needs. At the same time, the connecting through holes on the side panel increase the possibility of connecting the device to other components, improving the device's versatility. During use, the cooperation between the slide rail base and the bottom slide rail ensures smooth drawer operation, improving the user experience. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a partition locking device. (Refer to...) Figure 1 , Figure 2 and Figure 3A partition locking device includes a drawer body 1 and positioning slides 2 disposed on both sides of the lower end of the drawer body 1. The positioning slides 2 include a support body 21 and a slide rail seat 22. The slide rail seat 22 is fixedly installed on the upper end surface of the support body 21. Bottom slide rails 11 that slide in cooperation with the slide rail seat 22 are installed on both sides of the lower end surface of the drawer body 1. The bottom slide rails 11 are fixedly connected to the drawer body 1. A linkage seat 3 is also installed on the rear end surface of the drawer body 1. The linkage seat 3 includes a positioning seat 31 and a linkage shaft 32. The positioning seats 31 are configured in two sets, and the two sets of positioning seats 31 are fixedly installed on both sides of the rear end surface of the drawer body 1. The two ends of the linkage shaft 32 are rotatably installed on the positioning seats 31, and the two ends of the linkage shaft 32 are also fixedly installed with snap-fit ​​pieces 4. The tail of the snap-fit ​​piece 4 is connected to the positioning seat 31 through a tension spring 40. An adjustable snap block 5 corresponding to the snap-fit ​​piece 4 is also installed on the support body 21. Two sets of positioning slides 2 are fixedly installed on the inner wall of the cabinet, thus providing auxiliary support for the drawer body 1 and ensuring that the drawer body 1 can slide stably on the support body 21 during use. The cooperation between the slide rail base 22 and the bottom slide rail 11 provides a smooth track for the drawer to be pulled out, reduces frictional resistance, and improves the convenience of using the drawer. By installing a linkage seat 3 on the rear end face of the drawer body 1, and designing the linkage seat 3 as a structure in which the positioning seat 31 and the linkage shaft 32 cooperate, it is ensured that the linkage shaft 32 can be positioned and installed by two sets of positioning seats 31 during use, so that the linkage shaft 32 can rotate stably. At the same time, by fixing the locking parts 4 at both ends of the linkage shaft 32, it is ensured that the locking parts 4 at both ends can be flipped synchronously. When using it, operating one end can rotate synchronously, making it easier and more convenient to operate. At the same time, by installing an adjustable locking block 5 corresponding to the locking part 4 on the support body 21, the locking part 4 and the adjustable locking block 5 can be locked together under the action of the tension spring 40 when no external force is applied. This way, the drawer body 1 can be automatically locked after being pulled out, ensuring the stability of the drawer body 1 during use. When it is necessary to unlock, the user only needs to manually lift the locking part 4 to return the drawer body 1 to its original position.

[0032] Reference Figure 5 and Figure 6The support body 21 includes a base plate 211 and a side plate 212. The side plate 212 is vertically installed on one side of the base plate 211, and a bracket 213 for mounting the slide rail 22 is provided on the other side of the base plate 211. Both the side plate 212 and the bracket 213 are fixedly connected to the base plate 211. By designing the support body 21 into a structure in which the base plate 211 and the side plate 212 cooperate, it is ensured that the side plate 212 can be used to cooperate and fix with the cabinet. The base plate 211 facilitates the stable installation of the adjustable latch 5. The bracket 213 is fixedly installed on the base plate 211, which facilitates the support and fixation of the slide rail 22 by two sets of brackets 213. The bottom slide rail 11 on the lower end face of the drawer body 1 can be stably installed through the slide rail 22, allowing the bottom slide rail 11 to slide stably on the slide rail 22 to realize the pull-out of the drawer body 1. The base plate 211 has a guide groove 215 for installing the adjustable latch 5, and the side plate 212 has several sets of connecting through holes 214 evenly distributed. An anti-slip plate 221 is fixedly installed at the head of the slide rail 22, and a limiting groove corresponding to the anti-slip plate 221 is provided in the bottom slide rail 11. The guide groove 215 on the base plate 211 allows the adjustable latch 5 to be installed in the guide groove 215 and then slidably adjusted to change its position. This facilitates flexible determination of the installation position according to the drawer's usage requirements during installation. The connecting through holes 214 on the side plate 212 can be used to connect or fix to other components such as the cabinet, increasing the device's versatility. The cooperation of the anti-slip plate 221 and the limiting groove prevents the drawer body 1 from slipping off the slide rail 22, increasing the safety of the drawer.

[0033] Reference Figure 3 and Figure 4 The positioning seat 31 includes a main housing 311 and an extension plate 312. The extension plate 312 is installed on one side of the main housing 311 and is integrally formed with the main housing 311. By designing the positioning seat 31 into a structure where the main housing 311 and the extension plate 312 cooperate, the main housing 311 ensures that the linkage shaft 32 can be stably rotated and installed during use, while the extension plate 312 facilitates the positioning and installation of other components. An arc-shaped groove 313 is provided on the extension plate 312, and a positioning mounting plate 314 for mounting the tension spring 40 is also provided on the side of the extension plate 312. The positioning mounting plate 314 is integrally formed with the extension plate 312. By opening an arc-shaped groove 313 on the extension plate 312, the stability of the tail of the snap fastener 4 during the flipping process can be increased, and the stability of the snap fastener 4 during use can be increased. At the same time, by setting a positioning hanging plate 314 on the side of the extension plate 312, the head of the tension spring 40 can be stably fixed and installed.

[0034] Reference Figure 1 and Figure 4The locking component 4 includes a flipping part 41 and a triangular locking block 42. The flipping part 41 is sleeved and fixed to the head of the linkage shaft 32. The triangular locking block 42 is integrally formed on the lower end face of the flipping part 41. The tail of the flipping part 41 is provided with an arc-shaped tail plate 411 corresponding to the arc-shaped groove 313. The arc-shaped tail plate 411 is integrally formed with the flipping part 41. The integrally formed design of the flipping part 41 and the triangular locking block 42 of the locking component 4 results in a simple structure and high strength. The cooperation between the triangular locking block 42 and the adjustable locking block 5 can achieve effective locking and engagement. The corresponding arrangement of the arc-shaped tail plate 411 and the arc-shaped groove 313 further restricts the rotation range of the locking component 4 and improves the stability of the locking.

[0035] Reference Figure 5 and Figure 6 The adjustable locking block 5 includes a sliding block 51 and a beveled block 52 corresponding to the triangular locking block 42. The sliding block 51 is slidably installed in the guide groove 215, and the beveled block 52 is fixedly installed on the upper end face of the sliding block 51. The sliding block 51 of the adjustable locking block 5 can slide in the guide groove 215 and can be locked in different positions by the locking screw 511. The cooperation between the beveled block 52 and the triangular locking block 42 makes the locking and unlocking process smoother. The lower end of the sliding block 51 is equipped with a locking screw 511 that locks with the base plate 211, and the lower end face of the base plate 211 is provided with a positioning scale 216 that cooperates with the sliding block 51. The positioning scale 216 makes it convenient for users to accurately adjust the position of the adjustable locking block 5 during installation to adapt to different usage needs. After the position is determined, it can be fixed by the locking screw 511. At the same time, it is convenient for the two adjustable locking blocks 5 at both ends to be installed synchronously, avoiding deviations at both ends from affecting the overall use.

[0036] The implementation principle of the partition locking device in this application embodiment is as follows: During actual installation, first loosen the locking screw 511, adjust the position of the adjustable block 5 in the guide groove 215 according to actual needs, and then tighten the locking screw 511 after determining the position of the adjustable block 5 according to the indication of the positioning scale 216. Then, the bottom slide rail 11 is installed on the slide rail seat 22, ensuring that the bottom slide rail 11 can slide on the slide rail seat 22, and the drawer body 1 is prevented from sliding off the slide rail seat by bending the anti-slip plate into the limiting groove. This ensures the stable use of the drawer. When the drawer body 1 is pulled out, the locking piece 4 moves synchronously. When the triangular locking block 42 moves onto the inclined block 52, it automatically opens. When the triangular locking block 42 slides to the front face of the inclined block 52, it automatically locks with the inclined block 52 under the action of the tension spring 40. This prevents the drawer body 1 from automatically returning to its original position, making it convenient and easy to take and put away items. When the drawer needs to return to its original position, the operator manually lifts one end of the latch 4, and then the linkage shaft 32 drives the latches 4 at both ends to flip and open simultaneously to quickly unlock the drawer and automatically return the drawer body 1 to its original position. During installation, the front end of the positioning slide 2 can be slightly higher than the rear end to facilitate better return of the drawer body 1.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
