Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of partition devices, and more specifically to a drawer partition. Background Technology
[0002] Drawers, as a type of furniture that facilitates storage, can utilize dividers to partition space, allowing items to be categorized and placed efficiently, thus improving space utilization. Existing technology offers several solutions for extendable dividers, suitable for drawers of different sizes. These extendable dividers feature sliding tabs that can be adjusted to fit the drawer's dimensions. Locking the tabs effectively divides the drawer. The front and back ends of the divider must be pressed firmly against the two opposite side walls of the drawer; that is, the divider's length must be slightly larger than the drawer's dimensions to ensure stability. This necessitates that the locking mechanism of the tabs in the divider be elastic. After the tabs are locked, the divider is placed inside the drawer, and the locking mechanism can elastically deform, causing the divider to contact the drawer's inner side walls. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a drawer divider that can be extended and retracted to adapt to drawers of different sizes. When locked, it can undergo elastic deformation along the length direction, so that the divider abuts against the inner side wall of the drawer.
[0004] The technical solution of this utility model is to provide a drawer divider, including a housing and a sliding piece. One end of the housing is provided with a sliding piece outlet, and the sliding piece is slidably disposed within the housing and can extend out of the sliding piece outlet. One of the housing and the sliding piece is provided with a toothed rack, and the other is provided with an elastic limiting member and an elastic limiting drive member. The elastic limiting member is elastic and is used to limit the sliding piece by inserting into the teeth of the toothed rack or to unlock the sliding piece by retracting from the teeth of the toothed rack. The elastic limiting drive member is used to drive the elastic limiting member to insert into or retract from the teeth of the toothed rack. The elastic limiting drive member is provided with a locking structure, and the housing or the sliding piece on which the elastic limiting drive member is provided is provided with a locking engagement structure. The locking structure and the locking engagement structure cooperate to lock the elastic limiting drive member when the elastic limiting member is inserted into the teeth of the toothed rack.
[0005] Compared with the prior art, the drawer divider of this utility model has the following advantages: In this utility model, the sliding piece of the drawer divider can slide relative to the shell, that is, the length of the drawer divider can be extended and retracted to adapt to drawers of different sizes; after the elastic limiting member is inserted between the teeth of the toothed rack to limit the sliding piece, it limits the relative position of the sliding piece and the shell, that is, it limits the length of the drawer divider. Because the elastic limiting member is elastic, it generates a pre-tightening force on the toothed rack when elastic deformation occurs, and the length of the drawer divider can be slightly shortened before being put into the drawer. In this way, the drawer divider of this utility model can be easily and smoothly put into the drawer. The pre-tightening force of the elastic limiting member on the toothed rack can make both the front and rear ends of the drawer divider abut against the inner side wall of the drawer.
[0006] Preferably, the elastic limiting component includes a torsion spring, and the elastic limiting drive component includes a gear and a gear drive component. The torsion spring is mounted on the gear, and the gear drive component has a drive gear ring or drive rack that meshes with the gear. The gear drive component drives the gear to rotate, and the gear drives the torsion spring to rotate, causing one end of the torsion spring to insert or disengage between the teeth of the rack. This structure is simple, and it is convenient to insert or disengage one end of the torsion spring between the teeth of the rack. The elastic limiting drive component uses a meshing connection, which facilitates locking and prevents slippage.
[0007] Preferably, the end of the torsion spring used for inserting into the toothed rack has a bent horizontal portion, which abuts against the toothed rack. With this structure, the bent horizontal portion can contact the entire tooth lateral surface line of the tooth width when inserted into the toothed rack, resulting in a large contact area. Compared to point contact, this is safer and less prone to slippage.
[0008] Preferably, each tooth on the toothed rack has a smooth relief surface and a limiting recess on its front and rear sides, respectively. The bent horizontal part enters the limiting recess and abuts against the toothed rack, or slides out of the limiting recess along the smooth relief surface. With this structure, the limiting recess can effectively limit the bent horizontal part, preventing it from sliding out of the teeth due to excessive preload of the torsion spring when the drawer divider is placed in the drawer; the smooth relief surface allows the bent horizontal part to exit smoothly from the teeth, preventing it from being obstructed during exit. The smooth relief surface can be a sloping plane or a curved surface.
[0009] Preferably, the gear drive component includes a handle with a half gear and a wrench portion, the half gear meshing with the gear; the wrench portion has a spring-loaded latch with a laterally protruding locking portion, the locking structure including the locking portion, and the locking engagement structure including a locking hole, the locking portion being able to be inserted into the locking hole to lock the handle. With this structure, locking the handle is simple and convenient; simply press the wrench portion down towards the locking hole to engage the locking portion.
[0010] Preferably, the end of the locking part is provided with a relief slope. During the process of inserting the locking part into the locking hole, the relief slope serves to avoid obstructing the housing or sliding plate where the locking hole is located. With this structure, when the wrench part is pressed down in the direction of the locking hole, the relief slope slides on the side wall of the housing or sliding plate where the locking hole is located. The locking part can be regarded as a wedge, and the relief slope avoids obstructing the housing or sliding plate, which is conducive to the smooth entry of the locking part into the locking hole.
[0011] Preferably, the housing is provided with a handle shaft and a gear shaft. The gear is rotatably mounted on the gear shaft, the half gear is rotatably mounted on the handle shaft, the locking part is provided on the housing, and the rack is provided on the sliding plate. This structure is simple and easy to assemble.
[0012] Preferably, a torsion spring connecting shaft is provided in the middle of the gear, and a torsion spring limiting part is provided on the end face of the gear. The torsion spring is sleeved on the torsion spring connecting shaft, and one end of the torsion spring is inserted into the torsion spring limiting part and limited on the gear. This structure facilitates the assembly of the torsion spring.
[0013] Preferably, the housing includes a first outer shell and a second outer shell, which are arranged opposite to each other and joined together. The first outer shell has a first limiting wall protruding towards the second outer shell on the end face where the slide outlet is located. The slide has a first groove on the side opposite to the first limiting wall. The first limiting wall is inserted into the first groove, and the slide slides within the housing. The first groove avoids the first limiting wall, and the front and rear groove walls of the first groove limit the first limiting wall. A retaining rack is disposed on the lower groove wall of the first groove. This structure facilitates pulling the slide outwards while preventing the slide from completely dislodging from the housing.
[0014] Preferably, the second outer shell has a second limiting wall protruding towards the first outer shell on the end face where the slide outlet is located. The slide has a second groove on the side opposite to the second limiting wall. The second limiting wall is inserted into the second groove, and the slide slides within the shell. The second groove avoids the second limiting wall, and the front and rear groove walls of the second groove limit the second limiting wall. This structure facilitates pulling the slide outwards while preventing the slide from completely detaching from the shell and avoiding large-scale up-and-down floating of the slide within the shell.

The housing is provided with a slide rail 8, which is jointly formed by the bottom of the inner side of the first outer shell 1 and the bottom of the inner side of the second outer shell 2.
[0026] The housing is provided with a sliding piece 3, such as Figure 1 , Figure 3 and Figure 5 As shown, the sliding piece 3 is slidably disposed within the housing and extends out of the sliding piece outlet 7. The bottom of the sliding piece 3 is slidably connected to the slide rail 8. A first groove 3-1 is provided on the side of the sliding piece 3 opposite to the first limiting wall 1-1, and the first limiting wall 1-1 is inserted into the first groove 3-1. A second groove 3-2 is provided on the side of the sliding piece 3 opposite to the second limiting wall 2-1, and the second limiting wall 2-1 is inserted into the second groove 3-2. The sliding piece 3 slides within the housing. The first groove 3-1 avoids the first limiting wall 1-1, and the front and rear groove walls of the first groove 3-1 limit the first limiting wall 1-1. The second groove 3-2 avoids the second limiting wall 2-1, and the front and rear groove walls of the second groove 3-2 limit the second limiting wall 2-1. A toothed rack 3-3 is provided on the lower groove wall of the first groove 3-1, such as... Figure 6 As shown, each tooth on the toothed rack 3-3 has a smooth surface 3-4 for avoiding movement and a limiting recess 3-5 on its front and rear sides respectively.
[0027] The housing is provided with a sliding locking element, such as... Figures 3 to 5 As shown, the sliding plate locking component includes a rack and pinion 3-3, a handle 4, a gear 5, a torsion spring 6, and a handle limiting structure. A handle shaft 1-3, a gear shaft 1-4, and a locking hole 1-2 serving as the handle limiting structure are provided on the inner wall of the first housing 1. The gear 5 is rotatably mounted on the gear shaft 1-4. The handle 4 is provided with a half gear 4-5 and a wrench portion 4-1. The half gear 4-5 is rotatably mounted on the handle shaft 1-3 and meshes with the gear 5. The wrench portion 4-1 is provided with a spring clip 4-2, which has a laterally protruding locking portion 4-4. The locking portion 4-4 can be inserted into the locking hole 1-2 to lock the handle 4. The end of the locking portion 4-4 is provided with a clearance slope 4-3, which guides the housing during the insertion of the locking portion 4-4 into the locking hole 1-2.
[0028] A torsion spring connecting shaft 5-2 is provided in the middle of gear 5, and a torsion spring limiting part 5-1 is provided on the end face of gear 5. The middle part of torsion spring 6 is sleeved on torsion spring connecting shaft 5-2. One end of torsion spring 6 is inserted into torsion spring limiting part 5-1 and limited on gear 5. The other end of torsion spring 6 is provided with a bent horizontal part 6-1, which is used to extend into the inter-tooth locking sliding piece 3 of rack 3-3, such as... Figure 6 As shown, specifically, the sliding piece 3 can be locked by entering the limiting recess 3-5 and contacting the toothed rack 3-3, or it can be unlocked by sliding out of the limiting recess 3-5 along the smooth surface 3-4.
[0029] When using the drawer divider of this utility model, first lift the lever part 4-1 to unlock the handle 4 and the sliding piece 3. Then pull out the sliding piece 3 to the length of the drawer, so that the overall length of the drawer divider is slightly larger than the length of the drawer. Turn the handle 4 downward, and the half gear 4-5 drives the gear 5 to rotate. The gear 5 drives the torsion spring 6 to rotate, and the bent horizontal part 6-1 extends into the teeth of the locking rack 3-3. Then press the lever part 4-1 down towards the housing. The locking part 4-4 causes the housing to rotate slightly outward along the relief slope 4-3 until the locking part 4-4 smoothly enters the locking hole 1-2 to lock the handle 4. At this time, the sliding piece 3 is completely locked, and the length of the drawer divider of this utility model is adjusted.
[0030] During the process of placing the drawer divider of this utility model into the drawer, the torsion spring 6 is elastic and can push the sliding plate 3 to compress the torsion spring 6, so that the overall length of the drawer divider is slightly shortened, making it easier for the drawer divider to be placed into the drawer smoothly.
