Description

Technical Field

[0001] The utility model relates to the technical field of tool boxes, in particular to a tool box with a movable lock. Background Art

[0002] In order to facilitate the carrying and storage of various maintenance tools, various mechanical maintenance tools are usually stored in a tool box. However, the current tool box structure is relatively simple and can only be used to store maintenance tools. Due to the large variety of mechanical maintenance tools, maintenance tools are repeatedly taken out and used during carrying and use. After use, the staff only needs to put the various maintenance tools back into the tool box. However, it is easy for tools to be lost during the repeated use of maintenance tools. In addition, the existing tool box can only be used for storage and a certain limit card release. During the carrying process, due to bumps, it is easy for tools in the tool box to fall out of the card slot, causing various tools to collide and be damaged.

[0003] The existing anti-loss toolbox usually sets a sensor in the tool slot on the toolbox, and cooperates with the smart lock on the box cover. When the tool is missing, the smart lock on the box cover cannot be connected to the box body, but the cost of this structure is relatively high. And the existing buckle structure used on the toolbox usually consists of a fixed part and a movable part. The fixed part is fixed between the two objects to be fixed, and the movable part is connected to the fixed part by sliding, rotating or pressing. During the connection process, the movable part is usually locked with the fixed part by one or more locking mechanisms to maintain the connection between the two objects. The advantage of this structure is that it is simple, easy to manufacture and assemble, and low cost. However, its disadvantage is that during use, the locking and unlocking process of the buckle structure usually requires a large force or operating steps, which brings certain inconveniences to the user. Utility Model Content

[0004] The utility model aims to provide a tool box with an active latch to solve the problems of complicated locking and unlocking processes and inconvenience in use of the existing maintenance tool box.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A tool box with an active latch comprises: a box body, a fixing column vertically arranged in the middle of the box body, two locking mechanisms axially arranged on the fixing columns respectively, and two box covers arranged on both sides of the top of the box body and respectively locked or unlocked with the locking mechanisms on the fixing columns, one end of the two box covers contacting each other, and the bottom of the other end of the box covers being rotatably connected with the box body;

[0007] Symmetrical through grooves are respectively provided on both sides of the box body along the axial direction. The bottom of the locking mechanism passes through the fixed column and extends into the through groove. An anti-loss mechanism is slidably arranged in the through groove. The movable end of the anti-loss mechanism passes through the top of the box body and corresponds to the tool groove on the box body. When the end of the anti-loss mechanism located in the through groove lifts the locking mechanism, the locking mechanism is locked with the box cover.

[0008] When the toolbox of the utility model is in use, when all the tools are placed in the tool slot on the box body, the tool applies pressure to the movable end of the anti-lost mechanism, and when the end of the anti-lost mechanism lifts the locking mechanism, the locking mechanism is locked with the box cover; the anti-lost mechanism is manually driven to slide outward along the through slot, and at this time, the end of the anti-lost mechanism does not contact the locking mechanism, and the locking mechanism moves downward along the fixed column and extends into the through slot, and at this time, the box cover and the locking mechanism are unlocked, and the box cover can be rotated to open, and the tools for use are taken out from the tool slot of the box body. If the tools in the tool slot are not all placed, one of the movable ends of the anti-lost mechanism is not subjected to the pressure of the tool, and the anti-lost mechanism pulled out at this time cannot slide inward along the through slot, so that the box cover cannot be closed and locked. In order to close the toolbox smoothly, the staff will further check whether the tools inside the toolbox are complete, so as to play a reminder role and effectively prevent the maintenance tools from being lost. The anti-lost mechanism in the utility model cooperates with the locking mechanism to quickly lock or unlock the box cover, and has a simple structure, convenient operation, no complex electronic devices and sensors, etc., and saves more costs.

[0009] Furthermore, a fixing rod is connected between the inner walls on both sides of the through groove;

[0010] The anti-loss mechanism includes a plurality of movable components which are spaced apart and rotatably connected to the fixed rod, a slide plate which slides with the through slot, a limit stop post which is arranged on the top of the slide plate and located below the fixed rod, and a fixed baffle which is arranged on the top of the slide plate and located on the inner side of the limit stop post. The limit stop post corresponds to the movable components one by one, the movable end of the movable component passes through the top of the box body and corresponds to the tool slot on the box body, and the end of the slide plate which is located in the through slot is provided with a chamfered corner.

[0011] Furthermore, the above-mentioned movable component includes a first baffle, a second baffle corresponding to the first baffle, and a connecting column obliquely arranged on the second baffle, the first baffle and the corresponding second baffle are connected to the fixed rod through a torsion spring, the limit baffle column corresponds one-to-one with the first baffle, and the connecting column passes through the top of the box and corresponds to the tool slot on the box.

[0012] Furthermore, the length of the fixed baffle matches the width of the slide plate.

[0013] Furthermore, the fixing column is axially provided with a first through hole, a second through hole and a third through hole in sequence from top to bottom, and the diameter of the second through hole is larger than the diameters of the first through hole and the third through hole;

[0014] The locking mechanism includes a locking rod, the bottom of which passes through the first through hole, the second through hole and the third through hole in sequence and extends into the through groove. A limiting ring is provided on the outer wall of the locking rod located in the second through hole, and a spring is provided between the limiting ring and the top inner wall of the second through hole, and the spring is sleeved on the locking rod.

[0026] Symmetrical through slots 11 are respectively provided along the axial direction on both sides of the box body 1. The bottom of the locking mechanism 3 passes through the fixing column 2 and extends into the through slot 11. The locking mechanism 3 passes through the first through hole 21, the second through hole 22 and the third through hole 23 in sequence and extends into the through slot 11. An anti-lost mechanism 5 is slidably arranged in the through slot 11, and the movable end of the anti-lost mechanism 5 passes through the top of the box body 1 and corresponds to the tool slot on the box body 1. When the end of the anti-lost mechanism 5 located in the through slot 11 lifts the locking mechanism 3, the locking mechanism 3 is locked with the box cover 4. When the tools in the tool box need to be used, the anti-lost mechanism 5 is slid outward. At this time, the anti-lost mechanism 5 does not contact the locking mechanism 3, and the locking mechanism 3 extends into the through slot 11. At this time, the box cover 4 and the locking mechanism 3 are unlocked, and the box cover 4 can be used by rotating it open.

[0027] Specifically, a fixing rod 12 is connected between the inner walls of both sides of the through slot 11; the anti-loss mechanism 5 includes a plurality of movable components 51, a slide plate 52, a limit stop column 53 and a fixed stop plate 54, the movable components 51 are respectively spaced and rotatably connected to the fixed rod 12, the slide plate 52 is slidably matched with the through slot 11, the width of the through slot 11 is adapted to the width of the slide plate 52, the height of the through slot 11 is greater than the thickness of the slide plate 52, the limit stop column 53 is arranged at the top of the slide plate 52 and is located below the fixing rod 12, the fixed stop plate 54 is arranged at the top of the slide plate 52 and is located on the inner side of the limit stop column 53, wherein the side of the limit stop column 53 facing the outside of the through slot 11 is the outer side, and the side facing the inside of the through slot 11 is the inner side; the limit stop column 53 corresponds to the movable component 51 one by one, the movable end of the movable component 51 passes through the top of the box body 1 and corresponds to the tool slot on the box body 1, and the end of the slide plate 52 located in the through slot 11 is provided with a chamfer. Meanwhile, the length of the fixed baffle 54 in this embodiment matches the width of the slide plate 52 .

[0028] like Figure 3As shown, the movable assembly 51 includes a first baffle 511, a second baffle 512 corresponding to the first baffle 511, and a connecting column 513 obliquely arranged on the second baffle 512, and the connecting column 513 serves as the movable end of the anti-loss mechanism 5. In this embodiment, the first baffle 511 and the corresponding second baffle 512 are connected to the fixed rod 12 through a torsion spring, and the sides of the first baffle 511 and the second baffle 512 are both located on the same plane, and the first baffle 511 and the second baffle 512 are combined to form a bent connecting rod structure. Among them, the limit stop column 53 corresponds to the first baffle 511 one by one, and the connecting column 513 passes through the top of the box body 1 and corresponds to the tool groove on the box body 1. The top of the box body 1 is provided with a strip groove for the connecting column 513 to pass through, and the number of the strip grooves corresponds to the number of the connecting columns 513 one by one.

[0029] like Figure 4 As shown, the lock mechanism 3 includes a lock rod 31, the bottom of which passes through the first through hole 21, the second through hole 22 and the third through hole 23 in sequence and extends into the through groove 11, the aperture of the first through hole 21 is equal to the aperture of the third through hole 23, and the apertures of the first through hole 21 and the third through hole 23 match the rod diameter of the lock rod 31, the outer wall of the lock rod 31 located in the second through hole 22 is provided with a limit ring 32, a spring 33 is provided between the limit ring 32 and the top inner wall of the second through hole 22, and the spring 33 is sleeved on the lock rod 31, the bottom of the lock rod 31 is in an arc-shaped structure, and the top of the lock rod 31 is engaged with the box cover 4. The top inner wall of the box cover 4 is provided with a connecting block 41 corresponding to the lock rod 31, and the connecting block 41 is engaged with the top of the lock rod 31. Specifically, a mounting hole corresponding to the locking rod 31 is provided on the connecting block 41, and an annular groove is provided on the inner wall of the mounting hole in the radial direction. An arc-shaped protrusion is provided in an annular manner on the top of the locking rod 31, and the arc-shaped protrusion is engaged with the annular groove, thereby achieving the engagement between the locking rod 31 and the connecting block 41. The locking mechanism 3 is provided in at least two groups, and the number of the locking mechanism 3 corresponds to the number of the connecting blocks 41. Meanwhile, in the present embodiment, four locking mechanisms 3 are provided, and are evenly distributed at the four corners of the fixing column 2.

[0030] The tool box with active locking of the utility model is used when all tools are placed in the tool grooves on the box body 1, and the box cover 4 is rotated and closed on the box body 1. The connecting column 513 serves as the movable end of the anti-loss mechanism 5. When the tools are placed in the tool grooves, downward pressure is applied to the connecting column 513. At this time, the first baffle plate 511 and the second baffle plate 512 rotate under the pressure, and make the first baffle plate 511 higher than the height of the limit stop column 53. At this time, the slide plate 52 can slide inward along the through groove 11 of the box body 1. The end of the slide plate 52 is provided with a chamfered corner, and the bottom of the locking rod 31 is in an arc-shaped structure. The slide plate 52 is pushed to lift the locking rod 31, and the locking rod 31 moves upward along the fixed column 2 and is engaged with the connecting block 41 on the box cover 4 to achieve the locking of the box cover 4.

[0031] When it is necessary to open the box cover 4, the slide plate 52 is manually driven to slide outward along the through groove 11. Since the height of the second baffle plate 512 is lower than the height of the fixed baffle plate 54, the slide plate 52 will not slide out completely under the action of the second baffle plate 512. At this time, the slide plate 52 is not in contact with the locking rod 31, and the locking rod 31 moves downward along the fixed column 2 under the elastic force of its spring 33 and extends into the through groove 11. The limit ring 32 on the locking rod 31 can limit the axial movement position of the locking rod 31 along the fixed column 2, and the top of the locking rod 31 is loosened from the connecting block 41 on the box cover 4. At this time, the box cover 4 can be opened by rotation, and the tool for use can be taken out from the tool slot of the box body 1.

[0032] If not all the tools in the tool slot are placed, the connecting column 513 corresponding to the tool slot for taking out the tools is not subjected to the pressure of the tools. Therefore, the first baffle plate 511 and the second baffle plate 512 corresponding to the connecting column 513 rotate along the fixing rod 12 under the action of the torsion spring, and make the height of the first baffle plate 511 lower than the height of the limiting baffle column 53. Therefore, when the slide plate 52 is pushed to slide into the through slot 11, it will be limited by the first baffle plate 511 and cannot slide, and the box cover 4 cannot be closed. In order to close the tool box smoothly, the staff will further check whether the tools inside the tool box are complete, thereby serving as a reminder and effectively preventing the maintenance tools from being left behind or lost.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
