Description

Technical Field

[0001] This utility model relates to the field of toolbox technology, specifically to a handle-type structure for a toolbox. Background Technology

[0002] In industries such as manufacturing, maintenance, and home improvement, toolboxes are important carriers for various tools. Their structural design directly affects the ease of use and safety. The handle-type structure of a toolbox is designed to make it easier for users to lift and move the toolbox.

[0003] However, existing toolboxes with a handle-style design typically use a single handle, relying on the hand to directly bear the entire weight of the toolbox and tools. The stress point of a single handle is concentrated at the top of the toolbox, making it prone to swaying from side to side when lifted. Especially during movement, the shift in the center of gravity may cause tools to collide and be damaged or the toolbox to tip over due to inertia, posing a safety hazard. Furthermore, the connection between the traditional handle and the toolbox is subjected to heavy loads over a long period of time, which can easily lead to problems such as loose screws and broken plastic parts. In particular, the welded joint between the metal handle and the toolbox may crack due to stress concentration, shortening the toolbox's lifespan. Utility Model Content

[0004] The purpose of this utility model is to provide a handle-type structure for a toolbox. This handle-type structure solves the problems of existing toolbox handle-type structures being unable to support and restrict the bottom of the box 1 during use, resulting in tool collision damage or box shaking, as well as breakage at the connection between the handle and the box.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A toolbox with a handle-type structure includes a handle disposed on the outside of the box body, and a box cover mounted on the top of the box body; it also includes a movable component for supporting the bottom of the box body when lifted; and a fixed component for restricting the movable component; the movable component includes: a fixed block, which is fixedly mounted on the outside of the box body, a slider slidably connected inside the fixed block, the handle hinged to the outer wall of the slider, a fixed strip fixedly mounted on the surface of the fixed block, a short rod hinged to the surface of the fixed strip, a fixed plate fixedly mounted on the outer wall of the box body, a movable rod hinged to the inner side of the fixed plate, the short rod hinged to the middle end of the movable rod, and a support plate fixedly mounted at the bottom of the movable rod.

[0007] Preferably, a fixing spring is fixedly installed at the bottom of the slider, and the fixing spring is fixedly installed inside the fixing block.

[0008] Preferably, the fixing component includes: a fixing rod, which is fixedly installed on the top of the slider, a limiting rod is hinged to the surface of the fixing rod, one end of a torsion spring is fixedly installed on the inner side of the limiting rod, and the other end of the torsion spring is fixedly installed on the outer wall of the fixing rod.

[0009] Preferably, a positioning block is fixedly installed on the top of the housing, a limiting block is slidably connected inside the positioning block, and a control plate is fixedly installed on the top of the limiting block.

[0010] Preferably, a telescopic rod is fixedly installed inside the positioning block, the control plate is fixedly installed on the surface of the telescopic rod, and a movable spring is fixedly installed inside the telescopic rod.

[0011] Preferably, the active components are provided in two sets, and both sets of active components are symmetrically arranged with the center line of the box as the axis of symmetry.

[0012] Preferably, the top of the box is provided with a groove, and the cross-section of the limiting block is T-shaped.

[0013] By employing the above technical solution, this utility model provides a handle-type structure for a toolbox. It possesses at least the following beneficial effects:

[0014] (1) By setting the movable components, when the handle is pulled up, the slider and the fixing bar will slide up. When the fixing bar slides up, the movable bar will swing down through the short rod against the surface of the fixing plate. When the movable bar swings down, it will drive the tray to swing down, thereby moving the tray to the bottom of the box and lifting and restricting the bottom of the box. This prevents the box from swinging back and forth due to inertia during handling, avoids the box from tilting or the tool from shaking due to unstable center of gravity when lifting, and can distribute the weight of the box to the bottom, improve the stability of carrying, reduce the risk of handle breakage and extend the service life of the toolbox.

[0015] (2) By setting the fixing component, when the slider slides upward inside the fixing block, it will also drive the fixing rod to move upward. When the fixing rod moves upward, it will drive the limiting rod to pass through the groove of the box. After the limiting rod passes through the box, the limiting rod will be reset under the action of the torsion spring, so that the limiting rod is locked at the top of the box for restriction. The limiting rod is positioned by the limiting block inside the positioning block to prevent the tray from automatically retracting due to accidental force in the support state, and to avoid the sudden action of the weight of the box on the hand, causing the tool to fall or the hand to be injured. This ensures the stability and reliability of the moving component and avoids the safety hazards caused by misoperation. Attached Figure Description

Detailed Implementation

[0024] 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. Example 1

[0025] A toolbox with a handle-type structure, such as Figures 1-3 As shown, it includes a handle 2 located on the outside of the box 1, and a box cover 3 installed on the top of the box 1;

[0026] It also includes a movable component 4 for supporting the bottom of the lifted box 1;

[0027] Fixed component 5 is used to restrict the active component 4;

[0028] First, the movable component 4 includes: a fixed block 41, which is fixedly installed on the outside of the box 1. A slider 42 is slidably connected inside the fixed block 41. The handle 2 is hinged to the outer wall of the slider 42. A fixed strip 43 is fixedly installed on the surface of the fixed block 41. A short rod 44 is hinged to the surface of the fixed strip 43. A fixed plate 45 is fixedly installed on the outer wall of the box 1. A movable rod 46 is hinged to the inner side of the fixed plate 45. The short rod 44 is hinged to the middle end of the movable rod 46. A support plate 47 is fixedly installed at the bottom of the movable rod 46. The bottom of the box 1 can be supported by the movement of the support plate 47, and the sides of the box 1 can be supported when the support plate 47 is reset.

[0029] Secondly, a fixing spring 48 is fixedly installed at the bottom of the slider 42. The fixing spring 48 is fixedly installed inside the fixing block 41. The fixing spring 48 at the bottom of the slider 42 can achieve the effect of resetting after the slider 42 has been pulled.

[0030] In this embodiment, by setting the movable component 4, when the handle 2 is pulled upward, it will drive the slider 42 and the fixing bar 43 to slide upward. When the fixing bar 43 slides upward, it will contact the movable rod 46 on the surface of the fixing plate 45 through the short rod 44 and swing downward. When the movable rod 46 swings downward, it will drive the support plate 47 to swing downward, thereby moving the support plate 47 to the bottom of the box 1 and supporting the bottom of the box 1. This prevents the weight of the box 1 from being concentrated on the handle 2, causing excessive pressure on the hand. It also avoids the box 1 from tilting or the tool from shaking due to instability when lifting. The weight of the box 1 can be distributed to the bottom, improving the stability of carrying, reducing the risk of the handle 2 breaking, and extending the service life of the toolbox. Example 2

[0031] like Figures 4-6 As shown, the fixing component 5 includes: a fixing rod 51, which is fixedly installed on the top of the slider 42. A limiting rod 52 is hinged to the surface of the fixing rod 51. One end of a torsion spring 53 is fixedly installed on the inner side of the limiting rod 52, and the other end of the torsion spring 53 is fixedly installed on the outer wall of the fixing rod 51.

[0032] Furthermore, a positioning block 54 is fixedly installed on the top of the housing 1. A limiting block 55 is slidably connected inside the positioning block 54. A control plate 56 is fixedly installed on the top of the limiting block 55. A telescopic rod 57 is fixedly installed inside the positioning block 54. The control plate 56 is fixedly installed on the surface of the telescopic rod 57. A movable spring 58 is fixedly installed inside the telescopic rod 57. The movable spring 58 inside the telescopic rod 57 can achieve the effect of resetting when the telescopic rod 57 is stretched or retracted.

[0033] Finally, there are two sets of movable components 4, and both sets of movable components 4 are symmetrically arranged with the center line of the box 1 as the axis of symmetry. The two sets of movable components 4 can achieve uniform lifting of the box 1. The top of the box 1 is provided with a groove 10, which can be used to allow the fixing rod 51 and the limiting rod 52 to pass through the box 1. The cross-section of the limiting block 55 is T-shaped, which can be used to limit the movement of the limiting block 55.

[0034] In this embodiment, by setting the fixing component 5, when the slider 42 slides upward inside the fixing block 41, it will also drive the fixing rod 51 to move upward. When the fixing rod 51 moves upward, it will drive the limiting rod 52 to pass through the groove 10 of the box body 1. After the limiting rod 52 passes through the box body 1, the limiting rod 52 will be reset under the action of the torsion spring 53, so that the limiting rod 52 is locked at the top of the box body 1 for restriction. The limiting rod 52 is positioned by the limiting block 55 inside the positioning block 54 to prevent the tray 47 from automatically retracting due to accidental force in the supported state, and to avoid the sudden action of the weight of the box body 1 on the hand, which may cause the tool to fall or the hand to be injured. This ensures the stability and reliability of the moving component 4 and avoids the safety hazards caused by misoperation.

[0035] The toolbox of this utility model has a handle-type structure. In use, the box body 1 is the main structure for storing tools. The top is closed by the box cover 3, and the toolbox is lifted by the handle 2. When the handle 2 is pulled upward, it will drive the slider 42 to slide upward inside the fixed block 41. When the slider 42 slides upward, it will drive the fixed bar 43 to slide upward. When the fixed bar 43 slides upward, it will cause the movable rod 46 on the surface of the fixed plate 45 to swing downward through the short rod 44. When the movable rod 46 swings downward, it will drive the support plate 47 to swing downward, thereby moving the support plate 47 to the bottom of the box body 1 and supporting the bottom of the box body 1. This prevents the weight of the box body 1 from being concentrated on the handle 2, which would cause the hand to bear excessive pressure. It also avoids the box body 1 from tilting or the tools from shaking due to instability when lifting. With the support of the tray 47, the weight of the box 1 can be distributed to the bottom, which can reduce hand fatigue, improve carrying stability, reduce the risk of handle 2 breakage, and make the carrying process more effortless and safer. At the same time, it can reduce tool collision damage caused by inertia when carrying the toolbox and extend the service life of the toolbox. When the box 1 is placed, the handle 2 can drive the slider 42 to reset inside the fixed block 41 through the fixing spring 48 at the bottom of the slider 42, thereby driving the tray 47 to move away from the surface of the box 1, achieving an upward swinging effect. When the tray 47 swings upward, it will support the sides of the box 1, improving the stability of the box 1 when placed.

[0036] When the slider 42 slides upward inside the fixed block 41, it also drives the fixed rod 51 to move upward. When the fixed rod 51 moves upward, it drives the limiting rod 52 to pass through the groove 10 of the housing 1. When the limiting rod 52 passes through the housing 1, the groove 10 of the housing 1 will first abut against the limiting rod 52, causing the limiting rod 52 to move closer to the surface of the fixed rod 51. After the limiting rod 52 passes through the housing 1, the limiting rod 52 will be reset under the action of the torsion spring 53, so that the limiting rod 52 is locked at the top of the housing 1 for restriction, and is restricted by the limiting block 5 inside the positioning block 54. 5. Position the limiting rod 52 to prevent its movement. When it needs to be released, the limiting block 55 can be driven to abut against the surface of the limiting rod 52 by manually clamping the control plate 56. This allows the limiting rod 52 to continue moving closer to the surface of the fixed rod 51 and releases the limitation of the limiting rod 52 on the top of the box 1, thereby achieving the effect of releasing the fixation. This prevents the tray 47 from automatically retracting due to accidental force in the supported state, avoids the sudden weight of the box 1 acting on the hand, which could cause the tool to fall or the hand to be injured, and ensures the stability and reliability of the moving component 4, avoiding safety hazards caused by misoperation.
