Description

Technical Field

[0001] This utility model relates to the field of extraction aids, and in particular to a high-efficiency modular extraction aid. Background Technology

[0002] Modular chassis currently face multiple challenges in design and use: the excessive weight of a single module requires significant force for insertion and removal, compromising ease of operation; spatial layout is contradictory, as the reserved area for removal without an auxiliary tool occupies too much space, affecting the rational arrangement of internal components and the compact layout of components on the front panel. Furthermore, in high-density, heavy-load applications, the auxiliary tool must possess higher structural strength and reliability to reduce damage to the chassis, placing higher demands on traditional designs.

[0003] The modular pull-out aid, through innovative mechanical structure design, cleverly utilizes lever principles and spring force to achieve easy insertion, removal, and stable fixation of modules while ensuring structural strength. This design optimizes space utilization, avoids interference between the pull-out area and the internal component layout, and enhances structural reliability to meet the durability requirements of high-intensity usage scenarios, effectively improving the user experience and overall performance of the modular chassis.

[0004] Patent document CN207824777U discloses a pull-out aid, which consists of a pull-out aid pivot seat (1), a pull-out aid handle (2), a pull-out aid seat (3), a movable pivot (4), a fixed pivot (5), a rotating base rod (6), and a spring (7). The pull-out aid pivot seat (1) is provided with a rotation limiting groove (111) and a pivot seat limiting groove (112). The pull-out aid handle (2) is provided with a handle positioning rib (211), a sliding limiting pin (212), and a spring mounting post (213). The pull-out aid handle (2) is sleeved on the rotating base rod (6) and can slide along the axial direction of the rotating base rod (6). The handle positioning rib (211) can be inserted into the rotation limiting groove (111) and the pivot seat limiting groove (112). This utility model has a rotatable foldable pull-out aid structure, realizing the pull-out aid application of high-density interface board cards.

[0005] In the prior art of the aforementioned patent, the chassis is usually tightly embedded in the inner wall of the enclosure. The module is removed from the chassis using the aforementioned puller. However, during the removal process, the module and the enclosure come into contact with each other, resulting in significant friction. When removing the module using the puller handle, the hand must apply considerable force to the puller to remove the module, and there is also a risk of slipping, making it inconvenient to use. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency modular puller to address the aforementioned shortcomings in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency module puller, comprising two grooves disposed on the module body, wherein a puller is rotatably installed inside the grooves, and a roller is disposed at the end of each puller away from the module, wherein a wear-resistant layer is disposed on the surface of the roller, and a force-saving component is disposed on the puller.

[0008] As a further description of the above technical solution: a first pin is fixedly provided inside the groove, and an installation hole is provided on the pull-out part, and the pull-out part is rotatably connected to the first pin through the installation hole.

[0009] As a further description of the above technical solution: one end of the pull-out member is fixedly provided with an extension, a second pin is fixedly installed on the extension, and the roller is rotatably connected to the second pin.

[0010] As a further description of the above technical solution: three sealing gaskets are provided inside the mounting hole.

[0011] As a further description of the above technical solution: the end of the pull-out member away from the roller is provided with an upwardly bent portion.

[0012] As a further description of the above technical solution: the labor-saving component includes an abutment block fixedly installed at the bottom of the pull-out part. When the pull-out part is rotated, the abutment block can abut against the side wall of the module protrusion on the module body. The labor-saving component also includes a protrusion provided below the bending part.

[0013] This utility model provides a high-efficiency module puller. It has the following advantages: When it is necessary to remove the module body from the module shell, a portion of the bent part at the front end of the puller has a reserved space for fingers to enter and apply force. By inserting the fingers into the space at the front end of the bent part and pulling upwards, the puller rotates under the action of the first pin. During rotation, the rollers and the module shell roll against each other, causing the module shell to move upwards. The abutment block below the puller, after rotating to a suitable position, abuts against the top of the module protrusion, preventing the bending angle from being too large. Combined with the protrusion on the bent part, the fingers can be hooked below the protrusion, making it easier to remove the module body.

[0014] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0015] This application provides an overview of various implementations or examples of the technology described in this disclosure, and is not a full disclosure of the entire scope or all features of the disclosed technology. Attached Figure Description
