Description

Technical Field

[0001] This utility model relates to the field of drawer cabinet technology, and in particular to a drawer cabinet that is easy to operate. Background Technology

[0002] Dressers are a common type of furniture, primarily used for storing items in homes and offices. They can be categorized into standard dressers with standard-sized drawers suitable for storing items of various sizes, multi-drawer dressers containing multiple small drawers suitable for categorizing and storing small items, and combination dressers that offer more customized storage options by combining drawer units of different sizes as needed. Dressers are an indispensable piece of furniture in modern homes and offices, providing not only practical storage space but also enhancing the tidiness and aesthetics of the space.

[0003] A search revealed Chinese Patent Publication No. CN204580472U, which discloses a drawer cabinet, comprising a cabinet body and drawers disposed within the cabinet body. The drawers and cabinet body are slidably connected in a front-to-back direction. The cabinet body includes a top panel, a bottom panel, a left side panel, a right side panel, and a rear side panel. The drawers include a bottom panel, a left side panel, a right side panel, a front side panel, and a rear side panel. The drawer cabinet also includes a limiting structure, which includes a limiting hole on the rear side panel of the cabinet body and a limiting protrusion on the rear side panel of the drawer. When the drawer slides backward, the limiting protrusion engages with the limiting hole. Push the drawer to slide it into the cabinet. Once the limiting protrusion engages with the limiting hole, the drawer and cabinet are relatively locked, preventing the drawer from sliding off the cabinet during transport. Pull the drawer to disengage the limiting protrusion from the limiting hole for normal use. It is easy to operate, simple in structure, and low in cost. While it achieves the goal of preventing the drawer from sliding off the cabinet during transport, when the drawer is in use, placing heavy objects on one side of the drawer for a long time will cause uneven stress and tilt to one side, reducing its lifespan and practicality. Furthermore, the limiting protrusion will wear down after repeated use, further reducing durability and usability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a drawer cabinet that is easy to operate, aiming to improve the problem that in the prior art, if heavy objects are placed on one side of the drawer for a long time, the drawer will be unevenly stressed and tilt to one side, resulting in a reduced service life and reduced practicality.

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a drawer cabinet with simple operation, including a cabinet body 1. Multiple first guide grooves 3 are provided on the front side of the cabinet body 1, which supports the entire structure. A third guide groove 23 is provided near the edge of the front side of the first guide grooves 3. Multiple slots 24 are provided on the front side of the inner wall of the third guide groove 23, which guides the installation of the drawers. Multiple second guide grooves 11 are provided at the bottom of the inner wall of the first guide grooves 3. A V-shaped plate 28 is fixedly connected to the inner wall of the second guide grooves 11. A moving rod 6 is slidably connected to the inner wall of the third guide groove 23. Multiple first rotating shafts 5 are rotatably connected to the outer wall of the moving rod 6. The third guide groove 23 guides the sliding of the moving rod 6. The outer wall of the 5 is rotatably connected to a support block 4. The front side of the moving rod 6 is fixedly connected to a limit plate 8. The V-shaped plate 28 is used to push the support block 4 to rotate. The outer wall of the moving rod 6 is provided with a sliding plate 9 near the edge. Multiple locking blocks 7 are fixedly connected to the rear side of the sliding plate 9. The sliding plate 9 is used to drive the locking blocks 7 to move. The inner wall of the first guide groove 3 is fixedly connected to both the left and right sides of the guide rail 10. The inner wall of the guide rail 10 is slidably connected to a guide rod 12. Sliding boxes 13 are fixedly connected between adjacent guide rods 12. The guide rail 10 is used to determine the moving direction of the guide rod 12. The rear side of the guide rod 12 is fixedly connected to a self-locking structure 2. The self-locking structure 2 is used to self-lock and limit the drawer. The sliding box 13 is used to store items.

[0042] Specifically, the self-locking structure 2 can automatically lock the sliding box 13 when it is closed, preventing the drawer from sliding out accidentally. The support block 4 can rotate flexibly on the moving rod 6 with the first rotating shaft 5 to provide stable support for the drawer and prevent the drawer from tilting and shaking. The locking block 7 can be embedded in the slot 24 to lock the position of the moving rod 6 and ensure the stability of the drawer during use. The limiting plate 8 prevents the sliding plate 9 from sliding excessively and detaching from the outer wall of the moving rod 6, which would cause structural failure. The guide rail 10 can determine the sliding direction of the guide rod 12 and guide the sliding box 13 to slide along it.

[0043] Please see the appendix Figure 4 - Appendix Figure 6 The self-locking structure 2 includes a fixing block 210, the front side of which is fixedly connected to the rear side of the guide rod 12. A positioning groove 208 is formed on the inner wall of the fixing block 210, which is used to fix the entire self-locking structure 2. First sliding grooves 209 are formed on both the upper and lower sides of the inner wall of the positioning groove 208. A sliding rod 206 is slidably connected to the inner wall of the first sliding groove 209. Both the first sliding groove 209 and the positioning groove 208 are used for locking. A positioning block 207 is fixedly connected to the bottom end of the sliding rod 206, and a positioning block 207 is fixedly connected to the top end of the sliding rod 206. The outer wall of the positioning plate 204 and the sliding rod 206 is provided with a first spring 205, which is used to push the positioning block 207 to reset. Multiple fixing rods 201 are fixedly connected to the rear side of the inner wall of the first guide groove 3. The front end of the fixing rod 201 is fixedly connected to a hollow disk 203, which is used to support the hollow disk 203. The outer wall of the fixing rod 201 is provided with a sliding disk 202, and the inner wall of the sliding disk 202 is slidably connected to the outer wall of the fixing rod 201. The sliding disk 202 can help the positioning block 207 to disengage from the sliding disk 202.

[0044] Specifically, in its natural state, the first spring 205 provides an upward elastic force to the sliding rod 206, keeping it in a specific position. When subjected to an external force, the first spring 205 can compress and deform, storing energy. After the external force disappears, it quickly returns to its original shape, pushing the sliding rod 206 back to its original position. The diameter of the limiting disc 204 is larger than the width of the first groove 209. Its function is to prevent the sliding rod 206 from coming out of the first groove 209, and at the same time, it plays a limiting and buffering role during the sliding process.

[0045] Please see the appendix Figure 5 - Appendix Figure 7The sliding box 13 has a groove 14 on its front side. A rotating rod 15 is rotatably connected to the inner wall of the groove 14. The groove 14 is used to help the user pull the sliding box 13. A hollow tube 20 is rotatably connected to the outer wall of the third rotating shaft 21. A sliding rod 18 is slidably connected to the inner wall of the hollow tube 20. The hollow tube 20 is used to guide the sliding rod 18. A rotating plate 16 is rotatably connected to the outer wall of the rotating rod 15. The third rotating shaft 21 is rotatably connected to the rear side of the rotating plate 16. A second spring 19 is fixedly connected to the rear end of the sliding rod 18. The second spring 19 is used to push the sliding rod 18 to reset.

[0046] Specifically, when the sliding rod 18 slides forward under external force, the second spring 19 is gradually compressed, storing elastic potential energy. When the external force disappears, the second spring 19 quickly releases the stored elastic potential energy, pushing the sliding rod 18 to return to its initial position. This provides an automatic reset function for the movement of the sliding rod 18, which not only increases the convenience of operation but also protects other related components to a certain extent, reducing wear and damage that may be caused by frequent manual reset.

[0047] Please see the appendix Figure 3 - Appendix Figure 5 A base 26 is fixedly connected to each of the four corners at the bottom of the box 1. An anti-slip pad 27 is fixedly connected to the bottom of the base 26. The base 26 is used to support the entire box 1. A top cover 22 is fixedly connected to the top of the box 1. A hollow box 25 is fixedly connected to the front side of the sliding box 13. A second rotating shaft 17 is rotatably connected to the front end of the sliding rod 18. The hollow box 25 is used to place the sign.

[0048] Specifically, users can place various labels inside the hollow box 25 according to their storage needs to distinguish the categories of items in different drawers. The design of the top cover 22 not only provides dust protection for the items inside the box 1, preventing dust and other impurities from entering the drawer cabinet and affecting the cleanliness of the stored items, but also enhances the overall structural stability of the drawer cabinet to a certain extent, making the entire drawer cabinet more sturdy and durable. The anti-slip pad 27 increases the friction between the base 26 and the ground.

[0049] Working principle: When a heavy object is placed on one side of the sliding box 13, the sliding plate 9 is pulled forward first, thereby causing multiple locking blocks 7 to disengage from the locking slot 24. Then, the moving rod 6 is pulled along the top cover 22, which can drive multiple support blocks 4 to move along the second guide groove 11. At the same time, the support blocks 4 can gradually rotate and move upward along the V-shaped plate 28 through the first rotating shaft 5, thereby supporting the side of the sliding box 13 without the heavy object. This avoids the uneven force on the guide rail 10 caused by long-term heavy one side, which would cause the sliding box 13 to be unable to be pulled out smoothly.

[0050] When the sliding box 13 is pushed into the first guide groove 3, the hollow disk 203 can enter the positioning groove 208. Then, the chamfer of its outer wall aligns with the chamfer of the outer wall of the positioning block 207, squeezing the positioning block 207 and subsequently squeezing the sliding rod 206. This compression pushes the sliding rod 206 into the first sliding groove 209. When the positioning block 207 disengages from the hollow disk 203, it inserts between the hollow disk 203 and the sliding disk 202. At this point, pulling directly outward will not work because the hollow disk 203 has a single-sided chamfer. Therefore, pushing it backward is necessary. The sliding box 13 allows the positioning block 207 to fit against the chamfered outer wall of the sliding disk 202, thus retracting into the first groove 209. After disengaging, it enters the rear side of the sliding disk 202. At this time, pulling the sliding box 13 outward will cause the positioning block 207 to first pull the sliding disk 202 outward until the front side of the sliding disk 202 enters the sliding disk 202. Then, the chamfered rear side of the sliding disk 202 fits against the outer wall of the positioning block 207, thus allowing the positioning block 207 to be compressed back into the first groove 209 until it disengages from the hollow disk 203, thereby pulling the sliding box 13 outward.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
