Technical Field
[0001] This utility model relates to the field of toolboxes, and in particular to a pull-out combination toolbox. Background Technology
[0002] Toolboxes serve as storage containers for tools and various loose parts, and can be used in various aspects of production, daily life, and maintenance. They have a wide range of uses. In factories, small hardware fasteners are generally stored and carried in hardware toolboxes. Toolboxes are divided into mobile and fixed types, among which mobile toolboxes are further divided into hand-held, pull-out, and rolling types, etc.
[0003] Traditional pull-out toolboxes mostly consist of a box body and multiple drawers fitted inside. Tools are stored in the drawers, and to use them, the drawers are pulled out. For example, patent CN202122810126.3 mentions a pull-out multi-layer toolbox, including a handle, a top cover, a middle cover, a bottom cover, an inner liner, and a rotary switch. The handle is located on the front top of the top cover. Multiple middle covers are located between the top and bottom covers, each with an inner liner embedded in it. A rotary switch is located at the front end of each middle and bottom cover. The rotary switch is connected to a locking rod, which locks into the inner bottom of the front end of the next middle or top cover. Sliding grooves are located on the top sides of the middle and bottom covers, and sliding rails are located on the bottom sides of the top and middle covers, with adjacent sliding rails sliding in conjunction with the sliding grooves.
[0004] The aforementioned pull-out multi-layer toolbox uses a knob and locking lever for each layer's middle cover to lock with the upper or lower cover. This means that each layer's middle cover needs to be unlocked by rotating the corresponding knob, which is very cumbersome. Furthermore, this locking structure means that while pulling out the upper layer's middle cover unlocks it, all the lower layers' middle covers remain locked. This is because pulling out the upper layer's middle cover also pulls out the lower layers' covers. Moreover, due to the limitations of the slide rails and grooves, once the upper layer's middle cover is pulled out, the lower layer's middle cover cannot be unlocked; it must first be pushed back into place before the lower layer can be unlocked and pulled out. In actual use, it's impossible for users to accurately remember the location of different tools, leading to the need to pull out the middle covers multiple times to retrieve the required tool, which is extremely inconvenient. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a pull-out combination toolbox that is easy to lock and unlock.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a pull-out combination toolbox, the innovation of which is: it includes a box body and tool boxes stacked in sequence in the box body;
[0007] The toolbox has a cavity for storing tools. At least two of the toolboxes can be pulled out relative to the box body and are defined as movable toolboxes. The box body is also provided with a locking component for synchronously locking or unlocking all the movable toolboxes. The locking component includes a locking rod, and a locking block corresponding to each movable toolbox is provided on one side of the locking rod. A locking groove for moving the locking block into or out is also opened on the side of the movable toolbox. The locking rod is driven by a driving component to switch back and forth between a first position and a second position.
[0008] In the first position, the locking block on the locking lever is placed in the locking slot of the movable tool box, which is the locked state, and the movable tool box is fixed to the box body;
[0009] In the second position, the locking block on the locking lever is outside the locking slot of the movable toolbox. This position is the unlocked state, and the movable toolbox can be pulled out arbitrarily relative to the box body.
[0010] Furthermore, the drive assembly includes a rotating gear mounted on the housing, and a rack structure meshing with the rotating gear is also provided on one side of the locking lever. The rotating gear is driven to rotate by a knob, which in turn causes the locking lever to switch back and forth between a first position and a second position.
[0011] Furthermore, the outer wall of the housing is also equipped with markings on the knob to identify the locked state, unlocked state, and rotation direction.
[0012] Furthermore, the activity tool box includes a box body, with a locking groove on the side end of the box body to allow the locking block to move in or out, and a clearance groove on the side of the box body below the locking groove to allow the locking block to move. At the same time, a support guide section is formed on the side of the box body above the clearance groove to cooperate with the locking block, and the locking groove is formed on the support guide section.
[0013] Furthermore, the outer side of the box has a pull-out groove that allows a person to insert their hand and pull the box.
[0014] Furthermore, there are two locking components, located on both sides of the box, and locking slots that cooperate with the locking components are opened on both sides of the movable tool box.
[0015] Furthermore, in each of the stacked tool boxes, the tool box located on the top layer is fixed to the box body and is defined as the fixed tool box. The tool boxes located below the fixed tool box are all movable tool boxes. A box cover is also provided on the top of the fixed tool box. One side of the box cover is hinged to the fixed tool box, and the other side is fixed to the fixed tool box by a buckle. A handle is also hinged to the box cover.
[0016] Furthermore, the box body includes a bottom plate, side plates, and a sealing plate. There are two side plates and one sealing plate. The two side plates are respectively connected to the two sides of the sealing plate, and the side plates and the sealing plate work together to form a U-shaped structure that allows the movable tool box to be pulled out in one direction. The bottom end of the side plate is fixed to the bottom plate by bolts. A cavity is also opened on the side plate to accommodate the placement and vertical movement of the locking rod. A guide post is also provided in the cavity. At the same time, a guide groove is opened on the locking rod to accommodate the movement of the guide post. The bottom end of the sealing plate is inserted and fixed to the bottom plate, and the two sides of the sealing plate are also inserted and fixed to the side plates.
[0017] The advantages of this utility model are as follows: the toolbox of this utility model, through the cooperation of the locking rod, the locking block and the locking groove on the movable toolbox, can realize the synchronous locking or unlocking of all movable toolboxes with just one action, which is very convenient.
[0018] The locking lever is operated by a combination of a rotating gear, a knob, and a rack on the locking lever, resulting in a simple structure and easy operation. The markings on the housing are for use with the knob, allowing personnel to rotate the knob to the desired position.
[0019] The design of the movable toolbox uses a locking groove and a clearance groove to cooperate with the locking block. The locking groove is used to lock the locking block, while the clearance groove serves two purposes: first, it allows the locking block to pass through, so that the movable toolbox can be pulled out smoothly; second, when the movable toolbox is pulled out or pushed in, the cooperation between the locking block and the support guide section formed above the clearance groove creates a cooperation similar to a slide rail or slider, thereby guiding and supporting the translation of the movable toolbox, making the pulling out or pushing in of the movable toolbox smoother.
[0020] Using two locking components together to lock the toolbox provides a more stable lock and avoids the problem of one side of the toolbox becoming loose, which can occur when using a single-sided lock.
[0021] The box design adopts a combination structure of bottom plate, side plate and sealing plate. The side plate and sealing plate of different height can be replaced according to different numbers of tool boxes, making it more applicable. The sealing plate is connected to the bottom plate and side plate by plugging and fixing, thereby reducing the number of bolts required and making the structure simpler. Attached Figure Description

[0031] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0032] like Figures 1-9 The pull-out combination toolbox shown includes a box body 1 and tool boxes stacked sequentially in the box body. The tool boxes have cavities for storing tools. The tool boxes are divided into two types: movable tool boxes 2 and fixed tool boxes 3. The movable tool boxes 2 can be pulled out relative to the box body, while the fixed tool boxes 3 are directly fixed to the box body 1.
[0033] The box 1 includes a bottom plate 11, side plates 12, and a sealing plate 13. There are two side plates 12 and one sealing plate 13. The two side plates 12 are respectively connected to the two sides of the sealing plate 13, and the side plates 12 and the sealing plate 13 work together to form a U-shaped structure that allows the movable tool box 2 to be pulled out in one direction. The bottom end of the side plate 12 is fixed to the bottom plate 11 by bolts. On both sides of the bottom of the side plate 12, there is a protruding fixing protrusion 121. At the same time, there is a fixing groove 111 on the bottom plate 11 to accommodate the fixing protrusion 121. After the fixing protrusion 121 is inserted into the fixing groove 111, the bolt passes through the fixing groove 111 and is threaded to the fixing protrusion 121, thereby realizing the fixation between the side plate 12 and the bottom plate 11.
[0034] The bottom end of the sealing plate 13 is inserted and fixed to the bottom plate 11. A first insertion block 131 is provided on both sides of the bottom of the sealing plate 13. A first insertion groove 112 is opened on the bottom plate 11 to accommodate the insertion of the first insertion block 131. The two sides of the sealing plate 13 are also inserted and fixed to the side plate 12. A second insertion block 132 is provided on both sides of the sealing plate 13. A second insertion groove 122 is opened on the side plate 12 to accommodate the insertion of the second insertion block 132. The box design adopts a combined structure of bottom plate 11, side plate 12 and sealing plate 13. The side plate 12 and sealing plate 13 of different heights can be replaced to match the bottom plate 11 according to the number of tool boxes, without the need for a complete replacement, thus expanding the scope of application. The sealing plate 13 is connected to the bottom plate 11 and side plate 12 by plugging and fixing. The sealing plate 13 is fixed by plugging and fixing in multiple directions, thus eliminating the need for bolts to fix the sealing plate 13, thereby reducing the number of bolts required and making the structure simpler.
[0035] In this utility model, the topmost toolbox is a fixed toolbox 3. Below the fixed toolbox 3 are two movable toolboxes 2. Above the fixed toolbox 3 is a lid 4. One side of the lid 4 is hinged to the fixed toolbox 3, and the other side of the lid 4 is fixed to the fixed toolbox 3 by a buckle 42. A hinged handle 41 is also hinged to the lid 4, and a groove is provided on the lid 4 to accommodate the handle 41. The hinged handle 41 is designed to facilitate the movement of the entire toolbox by lifting it, while the groove on the lid 4 allows the handle 41 to be placed inside the groove when not in use, preventing it from protruding outside the toolbox.
[0036] The tool box 3 is fixed to the side plates 12 by bolts on both sides. A pair of protruding positioning protrusions 125 are provided on the side plates 12. Positioning grooves 32 that mate with the positioning protrusions 125 are also provided on both sides of the tool box 3. A pair of mounting plates 31 are also provided on each side of the tool box 3. A mounting groove 126 for the long strip 31 to be embedded is provided on the upper surface of the positioning protrusions 125. A through hole for bolts to pass through is provided on the mounting plate 31. An internal thread blind hole for threaded engagement with the bolt is provided on the positioning protrusions 124. During installation, the tool box 3 is quickly positioned between itself and the two side plates 12 by the engagement of the positioning protrusions 125 and the positioning grooves 32, and the mounting plate 31 and the mounting groove 126. Then, bolts are passed through the through holes on the mounting plate 31 and threadedly fixed to the positioning protrusions 125, thus completing the installation of the tool box 3.
[0037] One side of the fixed tool box 3 is supported on the sealing plate 13. A pair of third plug-in blocks 133 are also provided on the sealing plate 13. At the same time, a third plug-in slot is opened at the bottom of the fixed tool box 3 to accommodate the insertion of the third plug-in blocks 133. Through the cooperation of the third plug-in blocks 133 and the third plug-in slot, the fixed tool box 3 and the sealing plate 13 are relatively fixed. This also provides another upper limit for the fixing of the sealing plate 13 in a different direction, ensuring the stability of the sealing plate 13.
[0038] The housing 1 is also equipped with two locking components for simultaneously locking or unlocking all the movable toolboxes 2. These two locking components are located on opposite sides of the housing 1. Using two locking components in conjunction to lock the movable toolboxes 2 ensures a more stable lock and avoids the problem of one-sided loosening that can occur when using a single-sided lock.
[0039] like Figure 6 , Figure 7 As shown, the locking assembly includes a locking rod 5, which is a long strip-shaped structure. A cavity 123 is also provided on the side plate 12 to accommodate the locking rod 5 and allow it to move up and down. A pair of vertically distributed guide posts 124 are also provided in the cavity 123. At the same time, a guide groove 51 is also provided on the locking rod 5 to allow the guide posts 124 to extend into and move. Through the cooperation of the guide posts 124 and the guide groove 51, the locking rod 5 can play a guiding and limiting role when it moves up and down in the cavity 123, ensuring the smooth up and down movement of the locking rod 5.
[0040] On one side of the locking lever 5, there is a locking block 52 corresponding to each of the movable tool boxes 2. The movable tool box 2 includes a box body. A locking groove 21 is opened at the side end of the box body 2 to allow the locking block 52 to move in or out. On the side of the box body, below the locking groove 21, there is also a clearance groove 22 for avoiding the locking block 52 and allowing the locking block 52 to move. At the same time, a support guide section 23 is formed on the side of the box body above the clearance groove 22, which cooperates with the locking block 52. The locking groove 21 is opened in the support guide section. On the side plate 12, a support block 120 is also provided on the side plate 12 to cooperate with the support guide section 23. There are two support blocks 120 that cooperate with the same movable tool box 2. A gap is left between the two support blocks 120 to accommodate the locking block 52. The support block 120 and the locking block 52 cooperate with the support guide section 23 to form a support guide, so as to ensure that the movable tool box 2 can be guided and supported when it is pulled out or pushed into the box 1, and to ensure that the movable tool box 2 moves smoothly.
[0041] There is also a pull-out groove 24 on the outside of the box, which allows a person to reach in and pull the box. The design of the pull-out groove 24 on the outside of the box is to facilitate the person to pull out the tool box 2.
[0042] The locking lever 5 is driven by a drive assembly to switch back and forth between a first position and a second position.
[0043] In the first position, the locking block 52 on the locking lever 5 is placed in the locking groove 21 of the movable tool box 2. This position is the locked state, and the movable tool box 2 is fixed to the box body 1.
[0044] In the second position, the locking block 52 on the locking lever 5 is located outside the locking slot 21 of the movable tool box 2. This position is the unlocked state, and the movable tool box 2 can be pulled out arbitrarily relative to the box body 1.
[0045] The drive assembly includes a rotating gear 127 mounted on a side plate 12 of the housing 1. The side plate 12 also has a mounting cavity 128 for the rotating gear 127 to be embedded and installed, and the mounting cavity 128 is connected to the cavity 123. A rack structure 53 that meshes with the rotating gear 127 is also provided on one side of the locking rod 5. The rotating gear 127 is placed in the mounting cavity 128, and one side of the rotating gear 127 passes through the mounting cavity 128 and is connected to a knob 129. The knob 129 drives the rotating gear 127 to rotate and drive the locking rod 5 to move up and down, thereby switching back and forth between the first position and the second position.
[0046] On the outer wall of the side panel 12, at the knob 129, there are also markings for identifying the locked state, unlocked state, and rotation direction. The markings on the side panel 12 are designed to work in conjunction with the knob 129 so that personnel can quickly rotate the knob 129 to the desired position.
[0047] Working principle: Under normal conditions, the locking lever 5 is in the high position. At this time, each locking block 52 on the locking lever 5 is placed in the locking groove 21 of the movable tool box 2, that is, in the first position. When it is necessary to pull out the movable tool box 2 to take out tools, the operator turns the knob 129 according to the marking. The rotation of the knob 129 drives the rotating gear 127 to rotate, which in turn drives the locking lever 5 to move downward through the cooperation of the rack structure 53 on the locking lever 5, that is, from the first position to the second position. At this time, each locking block 52 on the locking lever 5 moves from the locking groove 21 to the clearance groove 22, releasing all the locking of the movable tool box 2. At this time, the operator can pull out the movable tool box 2 arbitrarily through the pull-out groove 24 to select the required tools.
[0048] After use, push the movable toolbox 2 back into the housing 1, then turn the knob 129 in the opposite direction to drive the locking lever 5 to move upward, and move it from the second position to the first position again, thus locking all the movable toolboxes 2.
[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
