Description

Technical Field

[0001] This utility model relates to the field of fire truck auxiliary equipment technology, and in particular to a flip-up drawer structure. Background Technology

[0002] Rescue fire trucks are equipped with various fire rescue equipment, special protective gear for firefighters, fire demolition tools, and fire detectors. They are dedicated fire trucks tasked with rescue missions. Rescue fire trucks typically have various drawers for storing fire equipment and tools. Since conventional drawers can only be pulled horizontally, when they are positioned high above eye level, the contents are not visible when the drawer is pulled out, making it inconvenient to access items.

[0003] For the reasons mentioned above, people have designed slanted drawers (such as the slanted drawer slide disclosed in application number 201010544813.9). When the drawer is pulled out, it slides down along the guide wheels, while the sliding block moves diagonally upwards along the slide rail. In this way, the front wheels of the drawer rotate downwards with the guide wheels as the fulcrum until they reach the maximum working position. At this point, the drawer tilts downwards, making it convenient for operators to access items. However, this slanted drawer structure is suitable for drawers with greater depth because the tilt angle of the drawer is affected by the tilt angle of the slide rail. For drawers with less depth, the tilt angle of the slide rail is also smaller, which results in the drawer tilting only slightly after it is pulled out, making it difficult for the human eye to see the items inside. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a flip-up drawer structure to solve the technical problem in the prior art that when the drawer is arranged in a high position, it is above the eye level, and when the drawer is pulled out, the human eye cannot see the items inside the drawer, making it inconvenient to store and retrieve items.

[0005] To achieve the above technical objectives, the present invention provides a flip-up drawer structure, comprising: A slide rail assembly includes a track component and a sliding component, wherein the sliding component is slidably connected to the track component and can move along the length direction of the track component; A drawer assembly connected to the slider and rotatable relative to the slider to adjust its own tilt angle; A locking assembly includes a connector and a locking member, the connector being connected to the slider and the locking member being connected to the drawer assembly, the locking member and the connector having a connected state to lock the drawer assembly and a separated state to unlock the drawer assembly.

[0006] Furthermore, the sliding member includes a straight slide rod and a rotating shaft. One end of the rotating shaft is fixedly connected to the outer end of the straight slide rod, the drawer assembly is rotatably connected to the other end of the rotating shaft, and the connecting member is fixedly connected to the other end of the rotating shaft.

[0007] Furthermore, the drawer assembly includes a drawer body and a limiting rod. A sliding groove is provided on the side wall of the drawer body. Before the drawer body is flipped over, the sliding groove on it is parallel to the straight sliding rod. The sliding groove is slidably connected to the other end of the rotating shaft. The limiting rod is fixedly installed in the drawer body and is parallel to the sliding groove. The locking member is slidably connected to the limiting rod and can reciprocate along the length direction of the limiting rod.

[0008] Furthermore, a limiting groove is formed on the limiting rod, the limiting groove including a first limiting groove segment and a second limiting groove segment. The first limiting groove segment is parallel to the sliding groove, the second limiting groove segment is perpendicular to the first limiting groove segment, and the first end of the second limiting groove segment is connected to the tail end of the first limiting groove segment. The locking member is slidably connected to the limiting groove.

[0009] Furthermore, the connecting member is a connecting shaft, which is disposed in the drawer body. One end of the connecting shaft is coaxially and fixedly connected to the other end of the rotating shaft. The locking member includes a locking shaft, a limiting pin, and two limiting caps. The locking shaft is disposed in the drawer body and is coaxial with the connecting shaft. One end of the locking shaft is engaged or disengaged from the other end of the connecting shaft. The limiting pin is perpendicular to the locking shaft and is detachably and fixedly connected to the locking shaft. The lower end of the limiting pin is slidably connected to the limiting groove. The two limiting caps are detachably and fixedly connected to the lower end of the limiting pin and slidably abut against the bottom and top surfaces of the limiting rod, respectively.

[0010] Furthermore, a fixed end face tooth is provided on the end face of the other end of the connecting shaft, and a movable end face tooth is provided on the end face of one end of the locking shaft. The movable end face tooth is engaged with or separated from the fixed end face tooth.

[0011] Furthermore, the locking shaft has a screw hole extending radially thereon, the limiting pin has a thread, the limiting pin passes through the screw hole and is screwed into the screw hole, the limiting cap is a nut, and two nuts are sleeved on the lower end of the limiting pin and are screwed into the limiting pin.

[0012] Furthermore, the locking assembly also includes a push-pull rod and an elastic element. The push-pull rod is slidably disposed within the drawer body and parallel to the slide groove. The push-pull rod can reciprocate between a first position and a second position along the length direction of the slide groove. The push-pull rod is also slidably connected to the locking element. When the push-pull rod reaches the first position, the locking element engages with the connecting element.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] This utility model provides a flip-up drawer structure, the structure of which is as follows: Figure 1 - Figure 3 As shown, the assembly includes a slide rail assembly 100, a drawer assembly 200, and a locking assembly 300. The slide rail assembly 100 includes a track member 110 and a slider member 120. The slider member 120 is slidably connected to the track member 110 and can move along the length direction of the track member 110. The drawer assembly 200 is connected to the slider member 120 and can rotate relative to the slider member 120 to adjust its tilt angle. The locking assembly 300 includes a connector 310 and a locking member 320. The connector 310 is connected to the slider member 120, and the locking member 320 is connected to the drawer assembly 200. The locking member 320 and the connector 310 have a connected state to lock the drawer assembly 200 and a separated state to unlock the drawer assembly 200.

[0019] In use, the track component 110 is fixedly connected to the cabinet body, and the sliding component 120 is slidably connected to the track component 110. When the drawer assembly 200 is pulled out, the sliding component 120 can move along the length direction of the track component 110. After the drawer assembly 200 is fully pulled out, the locking component 320 is operated to separate the locking component 320 from the connecting component 310. The locking component 320 then separates from the sliding component 120. At this time, the drawer assembly 200 can rotate relative to the sliding component 120, thereby adjusting its tilt angle. When the drawer assembly 200 reaches a suitable tilt angle, the locking component 320 is operated to separate the locking component 320 from the sliding component 120. When the connecting parts 310 are connected to each other, the locking part 320 is connected to the sliding part 120. At this time, the drawer assembly 200 is locked. After being pulled out, the drawer assembly 200 will not rotate downward relative to the sliding part 120 due to its own gravity. The drawer assembly 200 can be held in any position after being pulled out without the need for manual support, making it convenient for operators to take out and put in items. This flip-up drawer structure is suitable for placement in a high position. When the drawer assembly 200 is above eye level, after pulling out the drawer assembly 200, the drawer assembly 200 can be flipped downward to a suitable tilt angle, allowing the human eye to observe the items inside the drawer assembly 200, facilitating the storage and retrieval of items.

[0020] As a preferred embodiment, please refer to Figure 1 and Figure 2 The track component 110 includes a straight track 111 and two stops 112. The straight track 111 is horizontally arranged, and the two stops 112 are respectively fixed at both ends of the straight track 111. The sliding member 120 is slidably connected to the straight track 111. The two stops 112 can block and prevent the sliding member 120 from falling off the straight track 111.

[0021] As a preferred embodiment, please refer to Figure 1 and Figure 2 The sliding member 120 includes a straight slide rod 121 and a rotating shaft 122. One end of the rotating shaft 122 is fixedly connected to the outer end of the straight slide rod 121. The drawer assembly 200 is rotatably connected to the other end of the rotating shaft 122. The connecting member 310 is fixedly connected to the other end of the rotating shaft 122, thereby allowing the drawer assembly 200 to rotate relative to the sliding member 120.

[0022] In a preferred embodiment, the slider 120 further includes two sliding blocks, which are fixedly connected to the inner end and middle of the straight slide rod 121, respectively. Both sliding blocks are also slidably connected to the straight track 111. When the slider 120 moves outward along the length of the track 110, the middle sliding block abuts against the outer end of the straight track 111, which can limit the travel of the straight slide rod 121, allowing half of the straight slide rod 121 to slide out. At this time, the slid-out half of the straight slide rod 121 is in a suspended state, avoiding the deformation problem when the entire straight slide rod 121 is in a suspended state due to the entire slide out.

[0023] As a preferred embodiment, please refer to Figure 1 and Figure 2 The drawer assembly 200 includes a drawer body 210 and a limiting rod 220. A groove 211 is formed on the side wall of the drawer body 210. Before being flipped over, the groove 211 on the drawer body 210 is parallel to the straight sliding rod 121. The groove 211 is slidably connected to the other end of the rotating shaft 122. The limiting rod 220 is fixedly installed inside the drawer body 210 and is parallel to the groove 211. The locking member 320 is slidably connected to the limiting rod 220 and can reciprocate along the length of the limiting rod 220, thereby allowing the drawer body 210 to rotate relative to the sliding member 120, adjusting its tilt angle. It can also slide relative to the sliding member 120 to allow it to be fully pulled out. The drawer can only be flipped after it is fully pulled out. Before the drawer body 210 is fully pulled out, the locking member 320 and the connecting member 310 are in a connected state. When the other end of the rotating shaft 122 slides in the slide groove 211, it will drive the connecting member 310 to move along the length direction of the slide groove 211. Since the locking member 320 is connected to the connecting member 310, the locking member 320 will also move along the length direction of the slide groove 211. The locking member 320 can reciprocate along the length direction of the limiting rod 220. The limiting rod 220 can guide and limit the locking member 320. Under the premise that the locking member 320 can move synchronously with the connecting member 310, the locking member 320 will not rotate relative to the drawer body 210.

[0024] As a preferred embodiment, please refer to Figure 2The limiting rod 220 has a limiting groove 221, which includes a first limiting groove segment 2211 and a second limiting groove segment 2212. The first limiting groove segment 2211 is parallel to the slide groove 211, and the second limiting groove segment 2212 is perpendicular to the first limiting groove segment 2211. The first end of the second limiting groove segment 2212 is connected to the tail end of the first limiting groove segment 2211. The locking member 320 is slidably connected to the limiting groove 221. Before the drawer body 210 is fully pulled out, the locking member 320 and the connecting member 310 are in a connected state. When the other end of the rotating shaft 122 is in the slide groove 2211... When the drawer slides inward, the connecting member 310 will move along the length of the slide groove 211. Since the locking member 320 is connected to the connecting member 310, the locking member 320 will also move along the length of the slide groove 211. The first limiting groove segment 2211 of the limiting groove 221 is parallel to the slide groove 211. Therefore, the first limiting groove segment 2211 of the limiting groove 221 can guide the movement of the locking member 320 along the length of the slide groove 211, ensuring that the locking member 320 can move synchronously with the connecting member 310, and the locking member 320 will not rotate relative to the drawer body 210.

[0025] As a preferred embodiment, please refer to Figure 2The connecting member 310 is a connecting shaft 311, which is disposed inside the drawer body 210. One end of the connecting shaft 311 is coaxially and fixedly connected to the other end of the rotating shaft 122. The locking member 320 includes a locking shaft 321, a limiting pin 322, and two limiting caps 323. The locking shaft 321 is disposed inside the drawer body 210 and is coaxial with the connecting shaft 311. One end of the locking shaft 321 is engaged or disengaged from the other end of the connecting shaft 311. The limiting pin 322 is perpendicular to the locking shaft 321 and is detachably and fixedly connected to the locking shaft 321. The lower end of the limiting pin 322 is slidably connected to the limiting groove 221. The two limiting caps 323 are detachably and fixedly connected to the lower end of the limiting pin 322 and slidably abut against the bottom and top surfaces of the limiting rod 220, respectively. Because the limiting pin 322 and the locking member 320 are engaged or disengaged from the connecting shaft 122, the locking member 320 is engaged or disengaged from the connecting shaft 122. The fixed shaft 321 is detachably fixedly connected, the lower end of the limiting pin 322 is slidably connected to the limiting groove 221, and the two limiting caps 323 are detachably fixedly connected to the lower end of the limiting pin 322. The two limiting caps 323 slidably abut against the bottom and top surfaces of the limiting rod 220, respectively. Therefore, the locking shaft 321 can be limited, so that the locking shaft 321 can only move relative to the drawer body 210 and cannot rotate relative to the drawer body 210. When one end of the locking shaft 321 is engaged with the other end of the connecting shaft 311, the drawer body 210 can be locked, so that the drawer body 210 will not rotate downward relative to the sliding member 120 due to its own gravity after being pulled out. The drawer body 210 can be held in any posture after being pulled out without human support, which is convenient for operators to pick up and put down items.

[0026] As a preferred embodiment, please refer to Figure 2 The other end of the connecting shaft 311 has a fixed end face tooth 3111, and the end face of the locking shaft 321 has a movable end face tooth 3211. The movable end face tooth 3211 can engage or disengage with the fixed end face tooth 3111. When the movable end face tooth 3211 on the locking shaft 321 engages with the fixed end face tooth 3111 on the connecting shaft 311, the drawer body 210 can be locked, so that the drawer body 210 will not rotate downward relative to the sliding member 120 due to its own weight after being pulled out. The drawer body 210 can be held in any posture after being pulled out without the need for manual support, making it convenient for operators to pick up and put down items.

[0027] As a preferred embodiment, please refer to Figure 2The diameter of the connecting shaft 311 is larger than the diameter of the rotating shaft 122. One end face of the connecting shaft 311 abuts against the inner wall of the drawer body 210, thereby forming a limit and preventing the rotating shaft 122 from moving laterally within the slide groove 211.

[0028] As a preferred embodiment, please refer to Figure 2 The locking shaft 321 has a threaded hole extending radially therein, and the limiting pin 322 has a thread. The limiting pin 322 passes through the threaded hole and is screwed into the threaded hole. The limiting cap 323 is a nut. Both nuts are sleeved on the lower end of the limiting pin 322 and are screwed into the limiting pin 322. Thus, the limiting pin 322 can be limited by the two nuts, so that the limiting pin 322 can only slide along the length direction of the limiting groove 221 and cannot rotate relative to the limiting rod 220. That is, the locking shaft 321 can be limited.

[0029] As a preferred embodiment, please refer to Figure 2 and Figure 3 The locking assembly 300 further includes a push-pull rod 330 and an elastic element 340. The push-pull rod 330 is slidably disposed within the drawer body 210 and parallel to the slide groove 211. The push-pull rod 330 can reciprocate between a first position and a second position along the length direction of the slide groove 211. The push-pull rod 330 is also slidably connected to the locking element 320. When the push-pull rod 330 reaches the first position, the locking element 320 engages with the connecting element 310. When the push-pull rod 330 reaches the second position, the locking element 320 separates from the connecting element 310, and the elastic element 340 connects to the drawer. The component 200 and the push-pull rod 330 are used to bring the push-pull rod 330 to a first position. After the drawer assembly 200 is fully pulled out, operating the push-pull rod 330 can bring it to a second position. At this time, the locking member 320 is separated from the connecting member 310. The drawer assembly 200 is rotated downwards by hand. When the drawer assembly 200 reaches a suitable tilt angle, the push-pull rod 330 is released. Under the elastic force of the elastic member 340, the push-pull rod 330 returns to the first position. The locking member 320 and the connecting member 310 are engaged again to lock the drawer assembly 200.

[0030] As a preferred embodiment, please refer to Figure 2The push-pull rod 330 has a push-pull groove 331, which includes a first push-pull groove section 3311 and a second push-pull groove section 3312. The first push-pull groove section 3311 is parallel to the slide groove 211. The angle between the second push-pull groove section 3312 and the first push-pull groove section 3311 is an obtuse angle, and the first end of the second push-pull groove section 3312 is connected to the tail end of the first push-pull groove section 3311. The push-pull groove 331 is slidably connected to the upper end of the limiting pin 322. Before the drawer body 210 is fully pulled out, the locking member 320 and the connecting member 310 are in a connected state. When the other end of the rotating shaft 122 slides within the slide groove 211, it drives the connecting shaft 311 to move along the length of the slide groove 211. Since the locking shaft 321 of the locking member 320 is connected to the connecting shaft 311, the locking member 320 also moves along the length of the slide groove 211. The first limiting groove segment 2211 of the limiting groove 221 is parallel to the slide groove 211. Therefore, the first limiting groove segment 2211 of the limiting groove 221 can guide the movement of the limiting pin 322 of the locking member 320 along the length of the slide groove 211. The push-pull groove 331 The first push-pull groove section 3311 is parallel to the slide groove 211. Therefore, the first push-pull groove section 3311 of the push-pull groove 331 can guide the movement of the limiting pin 322 along the length direction of the slide groove 211. After the drawer body 210 is fully pulled out, the push-pull rod 330 is pulled outward, and the limiting pin 322 will enter the second push-pull groove section 3312 and the second limiting groove section 2212, and slide along the length direction of the second push-pull groove section 3312 and the second limiting groove section 2212. At this time, the limiting pin 322 is in the second push-pull groove section 3312 and the second limiting groove section 2212. Under the combined restraint of 12, the drawer body 210 will move away from the connecting shaft 311, thereby separating the movable end face tooth 3211 on the locking shaft 321 from the fixed end face tooth 3111 on the connecting shaft 311. When the drawer body 210 is rotated downwards by hand, and the drawer body 210 reaches a suitable tilt angle, the push-pull rod 330 is released. Under the elastic force of the elastic member 340, the push-pull rod 330 returns to the first position. The movable end face tooth 3211 on the locking shaft 321 and the fixed end face tooth 3111 on the connecting shaft 311 engage again, thereby locking the drawer body 210.

[0031] As a preferred embodiment, please refer to Figure 3 The elastic element 340 is a spring.

[0032] As a preferred embodiment, please refer to Figure 3The locking assembly 300 further includes a push-pull shaft 350, which is parallel to the push-pull rod 330. The inner end of the push-pull shaft 350 is fixedly connected to the outer end of the push-pull rod 330. The elastic element 340 is sleeved on the push-pull shaft 350. The push-pull shaft 350 can guide the elastic element 340 to prevent the elastic element 340 from tilting or shifting.

[0033] As a preferred embodiment, please refer to Figure 1 and Figure 3 The slide rail assembly 100 and the locking assembly 300 each include two components, which are arranged opposite to each other. The drawer assembly 200 also includes a handle 230, the two ends of which are fixedly connected to the outer ends of the two push-pull shafts 350. When a person pulls the handle 230 outward, the two push-pull rods 330 can be pulled outward simultaneously via the two push-pull shafts 350, thereby achieving synchronous pulling of the two push-pull rods 330 and thus synchronous unlocking of the two locking assemblies 300.

[0034] To better understand this utility model, the following is combined with... Figure 1 - Figure 3 The working principle of the technical solution of this utility model will be described in detail below: In use, the straight track 111 is fixedly connected to the cabinet body, the straight slide rod 121 is slidably connected to the straight track 111, and the rotating shaft 122 is slidably connected to the slide groove 211 on the drawer body 210. When the drawer body 210 is pulled out, the straight slide rod 121 can move along the length direction of the straight track 111, and the rotating shaft 122 can move along the length direction of the slide groove 211 until the drawer body 210 is completely pulled out. Before the drawer body 210 is fully pulled out, the movable end face tooth 3211 on the locking shaft 321 engages with the fixed end face tooth 3111 on the connecting shaft 311. When the other end of the rotating shaft 122 slides in the slide groove 211... This will cause the connecting shaft 311 to move along the length direction of the slide groove 211. Since the movable end face tooth 3211 on the locking shaft 321 engages with the fixed end face tooth 3111 on the connecting shaft 311, the locking member 320 will also move along the length direction of the slide groove 211. The first limiting groove segment 2211 of the limiting groove 221 is parallel to the slide groove 211. Therefore, the first limiting groove segment 2211 of the limiting groove 221 can guide the movement of the limiting pin 322 of the locking member 320 along the length direction of the slide groove 211. The first push-pull groove segment 3311 of the push-pull groove 331 is parallel to the slide groove 211. Therefore, the first push-pull groove segment 3311 of the push-pull groove 331 is parallel to the slide groove 211. The first push-pull groove section 3311 can guide the movement of the limiting pin 322 along the length direction of the slide groove 211. When the drawer body 210 is fully pulled out, the hand pulls the handle 230 outward, which can simultaneously pull the two push-pull rods 330 outward via the two push-pull shafts 350. The limiting pin 322 will enter the second push-pull groove section 3312 and the second limiting groove section 2212, and slide along the length direction of the second push-pull groove section 3312 and the second limiting groove section 2212. At this time, under the combined restraint of the second push-pull groove section 3312 and the second limiting groove section 2212, the limiting pin 322 will move away from the connecting shaft 311, thereby causing the locking shaft 321 to... The movable end face tooth 3211 separates from the fixed end face tooth 3111 on the connecting shaft 311. When the drawer body 210 is rotated downwards by hand, and the drawer body 210 reaches a suitable tilt angle, the push-pull rod 330 is released. Under the elastic force of the elastic element 340, the push-pull rod 330 returns to the first position. The movable end face tooth 3211 on the locking shaft 321 engages again with the fixed end face tooth 3111 on the connecting shaft 311, thus locking the drawer body 210. After being pulled out, the drawer body 210 will not rotate downwards relative to the sliding element 120 due to its own weight. The drawn drawer body 210 can remain in any posture without manual support.This flip-up drawer structure facilitates easy access for operators. Suitable for placement at a higher position, when the drawer assembly 200 is above eye level, it can be pulled out and flipped downwards to a suitable angle, allowing the contents to be easily observed and retrieved.

[0035] The flip-up drawer structure provided by this utility model has the following beneficial effects: (1) When the drawer body 210 is fully pulled out, the hand pulls the handle 230 outward, and the two push-pull rods 330 can be pulled outward simultaneously via the two push-pull shafts 350. The limiting pin 322 will enter the second push-pull groove section 3312 and the second limiting groove section 2212, and slide along the length direction of the second push-pull groove section 3312 and the second limiting groove section 2212. At this time, the limiting pin 322 will move away from the connecting shaft 311 under the joint limiting effect of the second push-pull groove section 3312 and the second limiting groove section 2212, thereby making the movable end face tooth 3211 on the locking shaft 321 separate from the fixed end face tooth 3111 on the connecting shaft 311, thereby unlocking the drawer body 210. (2) With this flip-up drawer structure, the drawer body 210 will not rotate downward relative to the sliding member 120 due to its own gravity after being pulled out. The drawer body 210 can be held in any posture after being pulled out without the need for manual support, which makes it convenient for operators to pick up and put down items. (3) This flip-up drawer structure is suitable for placement in a high position. When the drawer assembly 200 is above eye level, after the drawer assembly 200 is pulled out, the drawer assembly 200 can be flipped down to a suitable tilt angle, and the items inside the drawer assembly 200 can be observed by the human eye, making it convenient to store and retrieve items.
