Description

Technical Field

[0001] This utility model relates to the field of limiting mechanisms, and in particular to a toolbox drawer with an anti-slip limit. Background Technology

[0002] Drawers are a common storage device in toolboxes. When unlocked, drawers can be easily pulled out and closed, making them very convenient. However, since toolboxes are frequently moved during use, drawers can easily slide out due to vibrations, causing items to fall out or accidentally collide with surrounding objects. To prevent this, locks are typically used, but this requires a key for each drawer, which is inconvenient and can cause problems if damaged or lost. To address these issues, our company has developed a series of anti-slip mechanisms, such as CN200720067985 - A drawer limiting mechanism, CN201120172084 - Drawer anti-slip mechanism, etc. However, these anti-slip mechanisms involve many parts, making assembly complex and production costs high. Furthermore, with prolonged use, issues with fit can cause the lock hook to become stuck on the guide rail and difficult to release. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a toolbox drawer with an anti-slip limit, which can prevent slippage, and has a simpler structure, is less prone to jamming, and has a lower production cost.

[0004] To solve the above-mentioned technical problems, the present invention provides a toolbox drawer with an anti-slip limit, comprising a drawer and an anti-slip handle. Two slide rails are symmetrically installed on both sides of the drawer, each slide rail having an anti-slip groove at its top. The anti-slip handle is installed on the upper edge of the front panel of the drawer. The anti-slip handle further includes a handle plate, a connecting block, a locking hook plate, and a return spring. The handle plate is bent in the middle to form an assembly plate and a hand control plate. A pivot mounting groove is provided on the inner side of the handle plate along the bending line. A locking hook assembly groove parallel to the pivot mounting groove is provided on the inner side of the assembly plate. There are two locking hook plates, each consisting of a locking hook and a retaining plate. The locking hook and the retaining plate are perpendicular to each other, and the shape of the retaining plate is interference-fitted with the locking hook assembly groove. The plates are respectively engaged at both ends of the locking hook assembly slot; there are two connecting blocks, symmetrically fixed on both sides of the upper edge of the front panel of the drawer. Each connecting block has a mounting surface, a ramp surface, a positioning surface and a rotating shaft. The mounting surface is attached and fixed to the front panel of the drawer. The rotating shafts of the two connecting blocks are symmetrically installed at both ends of the rotating shaft mounting slot. At this time, the locking hooks on the two locking hook plates can just extend into the top of the slide rail on the corresponding side and hook the anti-slip hanging groove; the ramp surface is set between the rotating shaft and the mounting surface. The positioning surface is located on the other side of the rotating shaft. The ramp surface has a spring mounting position. The return spring is installed on the spring mounting position to open the ramp surface and the assembly plate until the inside of the hand control plate abuts against the positioning surface. At this time, the assembly plate is just perpendicular to the mounting surface.

[0005] In a preferred embodiment of this utility model, the bending angle of the handle plate and the angle between the ramp surface and the mounting surface are both obtuse angles. The sum of the difference between the bending angle and the angle between the ramp surface and the positioning surface, and the supplementary angle of the angle between the ramp surface and the mounting surface, is 90°. The bending angle of the handle plate and the angle between the ramp surface and the mounting surface are both between 90° and 150°.

[0006] In a preferred embodiment of the present invention, the mounting surface is provided with a plurality of screw mounting holes and at least two mounting positioning posts, and the front end panel of the drawer is provided with corresponding screw through holes and mounting positioning holes.

[0013] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0014] Please see Figures 1 to 5 The embodiments of this utility model include: A toolbox drawer with anti-slip limit is provided. The toolbox drawer with anti-slip limit includes a drawer 2 and an anti-slip handle 1. Two slide rails 3 are symmetrically installed on both sides of the drawer 2. Each slide rail 3 has an anti-slip groove at its top. The anti-slip handle 1 is installed on the upper edge of the front panel of the drawer 2. The anti-slip handle 1 also includes a handle plate 101, a connecting block 102, a locking hook plate 103, and a return spring 104. The handle plate 101 is bent in the middle to form an assembly plate 1012 and a hand control plate 1011. A pivot mounting groove 1012 is provided on the inner side of the handle plate 101 along the bending line. A locking hook assembly groove 1014 parallel to the pivot mounting groove 1013 is provided on the inner side of the assembly plate 1012. There are two locking hook plates 103. Both are composed of locking hooks 1031 and locking plates 1032. The locking hooks 1031 and locking plates 1032 are perpendicular to each other. The shape of the locking plates 1032 is interference-fitted with the locking hook mounting groove 1014. The locking plates 1032 of the two locking hook plates 103 are respectively inserted into the two ends of the locking hook mounting groove 1014. There are two connecting blocks 102, which are symmetrically fixed on both sides of the upper edge of the front panel of the drawer 2. Each connecting block 102 is provided with a mounting surface 1024 and a ramp surface 1024. 023. Positioning surface 1025 and rotating shaft 1021; mounting surface 1024 is attached and fixed to the front panel of the drawer 2; the rotating shafts 1021 of the two connecting blocks 102 are symmetrically inserted into the two ends of the rotating shaft mounting groove 1013; at this time, the locking hooks 1031 on the two locking hook plates 103 can just extend into the top of the slide rail 3 on the corresponding side and hook the anti-slip hanging groove; the inclined surface 1023 is set between the rotating shaft 1021 and the mounting surface 1024. The positioning surface 1025 is located on the other side of the rotating shaft 1021. A spring mounting position 1026 is provided on the ramp surface 1024. The reset spring 104 is installed on the spring mounting position 1026 to spread the ramp surface 1024 and the assembly plate 1012 so that the inside of the hand control plate 1011 abuts against the positioning surface 1025. At this time, the assembly plate 1012 is just perpendicular to the mounting surface 1024, that is, parallel to the bottom surface of the drawer 2.

[0015] The bending angle of the handle plate 101 and the angle between the ramp surface 1023 and the mounting surface 1024 are both obtuse angles between 90° and 150°. The sum of the difference between the bending angle and the angle between the ramp surface 1023 and the positioning surface 1025, and the supplementary angle of the angle between the ramp surface 1023 and the mounting surface 1024, is 90°. In actual implementation, the bending angle is generally 120°, and the angle between the ramp surface 1023 and the mounting surface 1025 is 115°. By adopting the above angle relationship, it can be ensured that when the return spring 104 is fully extended, the mounting surface 1012 of the handle plate 101 is exactly parallel to the bottom surface of the drawer 2. This allows the ramp surface 1023 to have about 65° of rotation space, providing sufficient space for the locking hook plate 103 to rotate until the locking hook 1031 disengages from the anti-slip groove when the drawer is pulled.

[0016] The mounting surface 1024 has three screw mounting holes 1028 and two mounting positioning posts 1029. All screw mounting holes 1028 and mounting positioning posts 1029 are distributed along a straight line, and the two mounting positioning posts 1029 are located on the outside of all screw mounting holes 1028. The front panel of the drawer 2 has corresponding screw through holes and mounting positioning holes. In this way, when the connecting block 102 is fixed to the front panel of the drawer 2, the mounting positioning posts 1029 can be quickly positioned before the drawer 2 and the anti-slip handle 1 are connected with screws, improving the overall assembly efficiency.

[0017] The connecting block 102 is provided with multiple structural cavities 10210, and the openings of all structural cavities 10210 are on the mounting surface 1024. The structural cavities 10210 can effectively reduce the total weight of the connecting block 102 while meeting the strength requirements of actual use, thereby reducing production costs. Furthermore, the openings of the structural cavities 10210 are on the mounting surface 1024, which can be covered during assembly to prevent affecting the overall appearance.

[0018] The spring mounting position 1026 is located at the inner end of the connecting block 102, and a positioning post is provided on the spring mounting position 1026. This arrangement of the spring mounting position 1026 facilitates the manual installation of the return spring 104 at the end of the assembly process, and the positioning post on the spring mounting position 1026 can effectively prevent the return spring 104 from falling off during use.

[0019] The connecting block 102 has a hook clearance groove 1027 at its outer end, and a handle baffle 1022 is provided on the outer side of the hook clearance groove 1027. The shape of the handle baffle 1022 is just enough to close the end of the handle plate 101 on the corresponding side. The hook clearance groove 1027 can provide space for the hook plate 103 to rotate, while the handle baffle 1022 can block both ends of the handle plate 101, preventing accidental damage to both ends of the handle plate 101 and improving the overall visual appearance.

[0020] The locking plate 1032 is provided with a reverse tooth groove, and a reverse tooth 1033 is installed in the reverse tooth groove. By setting the reverse tooth 1033, the locking plate 1032 can be prevented from slipping after insertion, thereby improving the stability of the locking hook plate 103 assembly.

[0021] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
