Description

Technical Field

[0001] This utility model belongs to the field of office supplies technology, and specifically relates to an adjustable height file organizer. Background Technology

[0002] Currently, file organizers are commonly used in corporate office environments to store and organize various types of office documents, materials, and files. Existing file organizers are generally of fixed height, with most using horizontally placed shelves for layered file storage, and the height of each shelf cannot be freely adjusted. When companies need to organize and store documents of different sizes or types, these fixed-height file organizers cannot flexibly adapt to usage needs, easily leading to wasted or insufficient space, and making file organization and retrieval inflexible and inconvenient.

[0003] To address these issues, some companies use removable shelves or pre-drilled holes for height adjustment in their file organizers. However, these solutions are cumbersome to operate and limited by the spacing of the pre-drilled holes, making precise and rapid height adjustments difficult and impractical. Therefore, companies urgently need a file organizer with a simpler structure, easier assembly, and more precise height adjustment to meet their daily office needs for flexible, convenient, and efficient layered file organization. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned defects and propose an adjustable-height file organizer. The main purpose is to solve the problem that the horizontal shelf height of the traditional file organizer is fixed, and the shelf spacing cannot be flexibly adjusted according to the actual height of the documents, materials and other items, resulting in low space utilization and difficulty in adapting to the storage needs of items of different sizes. By designing an adjustable shelf structure, the shelf height can be conveniently adjusted to meet diverse file organization and storage needs, and improve the flexibility and practicality of use.

[0005] The specific technical solution is as follows:

[0006] An adjustable-height file organizer includes:

[0007] Support base;

[0008] The support rods consist of four vertically arranged support rods forming a rectangular frame, which are fixed to the bearing base; the support rods have T-slots along the axial direction on the side facing the horizontal shelf.

[0009] The top plate is located at the top of the support rod and is fixedly connected to the support rods.

[0010] A horizontal shelf, with adjustment components connected to the corners of the horizontal shelf, and connected to the support rods through the adjustment components;

[0011] The adjustment assembly includes a slider, a brake cam, a support plate, and a connecting shaft. Two sliders are provided and connected by the connecting shaft, and are slidably sleeved in the T-slot of the support rod. The brake cam is sleeved on the connecting shaft and located between the two sliders. The support plate is connected to the brake cam and extends out from the opening of the T-slot to support the horizontal shelf. By pressing down on the support plate, the brake cam is rotated and thus locked into the T-slot.

[0012] Furthermore, the above solution includes slots for mounting corresponding support rods on both the bearing base and the top plate.

[0013] Furthermore, in the above scheme, the slider is rectangular, and the slider and the T-slot are in a clearance sliding fit.

[0014] Furthermore, in the above scheme, the thickness of the brake cam is consistent with the width of the T-slot opening.

[0015] Furthermore, the slider is coated with an iron-based alloy coating on the side of the horizontal plate and the surface of the brake cam profile.

[0016] Furthermore, the above solution includes a mounting hole at one end of the support plate corresponding to the horizontal shelf, and a positioning block corresponding to the mounting hole on the horizontal shelf.

[0017] Furthermore, in the above scheme, a torsion spring is provided between the brake cam and the slider, which causes the brake cam to twist downward toward the opening of the T-slot and lock into the T-slot.

[0018] Furthermore, in the above scheme, the torsion spring is a single-strand straight-wound torsion spring, which is mounted on the connecting shaft and its ends are respectively connected to the slider and the brake cam.

[0019] Furthermore, a connecting plate is provided between adjacent support plates in the above scheme.

[0020] Furthermore, in the above scheme, the support plate and the horizontal shelf are hinged together.

[0021] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0022] This utility model features an adjustable document organizer consisting of a vertical support rod, shelf assembly, and height adjustment mechanism, achieving flexible height adjustment and stable positioning of the shelves. The rack and pinion structure, engaged with positioning teeth, ensures the shelves remain stable and load-bearing after adjustment, preventing slippage. A wedge mechanism driven by an elastic button, combined with a return spring, allows for one-handed height adjustment, enhancing ease of use. The guide ridges and guide grooves effectively prevent shelf deflection, enhancing overall structural stability. The inverted trapezoidal cross-section positioning teeth, angled with the rack and pinion structure, further improve meshing tightness and impact resistance. Furthermore, the anti-accidental-touch flange and anti-friction coating optimize operational safety and mechanism durability, while the aluminum alloy support rod reduces overall weight while maintaining strength.

[0023] This invention comprehensively solves the problems of inconvenient adjustment and poor stability of traditional file racks, and features simple structure, efficient operation and strong adaptability. Attached Figure Description

[0032] Example 1

[0033] like Figures 1-5 As shown, this utility model discloses an adjustable height file organizer, including a support base 1, a support rod 2, a top plate 4, a horizontal shelf 3, and an adjustment component 6, for realizing stepless height adjustment of the horizontal shelf 3.

[0034] The support base 1 serves as a support unit, used to fix the support rod 2 to the top plate 4. The top plate 4 is located at the top of the support rod 2 and is fixedly connected to it. Both the support base 1 and the top plate 4 have slots for mounting the support rod 2. The support rod 2 serves as the core support of the entire document organizing rack. It consists of four vertically arranged support rods 2 forming a rectangular frame, which is fixed to the support base 1. The support rod 2 has a T-slot 5 along the axial direction on one side of the horizontal shelf 3. The support rod 2 can be made of aluminum alloy tubing or stainless steel tubing with T-slots 5, serving as the basis for adjusting the support of the adjustment assembly 6.

[0035] Adjustment components 6 are connected to the corners of the horizontal shelf 3, and are connected to the support rod 2 through the adjustment components 6. The horizontal shelf 3 is used as a support layer and can be made of iron or wood.

[0036] The adjusting assembly 6 includes sliders 7, brake cams 8, support plates 9, and connecting shafts 10. Two sliders 7 are provided and connected by the connecting shaft 10, and are slidably fitted within the T-slots 5 of the support rod 2. The brake cam 8 is fitted onto the connecting shaft 10 and located between the two sliders 7. The support plate 9 is connected to the brake cam 8 and extends out from the opening of the T-slot 5 to support the horizontal shelf 3. In use, pressing down on the support plate 9 causes the brake cam 8 to rotate and thus lock into the T-slot 5, while pressing up on the support plate 9 causes it to rotate and thus loosen the locking mechanism, thereby allowing the adjusting assembly 6 to move.

[0037] In the above scheme, the mechanical cooperation between the brake cam 8 and the T-slot 5 in the adjusting component 6 achieves fixed or movable adjustment. The horizontal shelf 3 is connected to the support rod 2 through the end corner adjusting component 6. Adjusting the adjusting component 6 achieves the adjustment of the horizontal shelf 3. Specifically, the slider 7 is slidably fitted inside the T-slot 5, the brake cam 8 is located between the two sliders 7, and the support plate 9 connects to the brake cam 8 and extends out of the T-slot 5 to support the shelf. When fixing is required, downward pressure is applied to the support plate 9, causing the brake cam 8 to rotate, making its contour fit tightly against the inner wall of the T-slot 5. The friction between the slider 7 and the T-slot 5, and between the brake cam 8 and the T-slot 5, secures it to the T-slot 5, thus fixing the height of the horizontal shelf 3. During adjustment, the horizontal shelf 3 needs to be lifted upwards, causing the support plate 9 and the brake cam 8 to rotate in opposite directions, releasing the brake cam 8 from the T-slot 5. At this time, the slider 7 can slide along the T-slot 5 to adjust the shelf height. After adjusting to the target height, pressing down the support plate 9 again completes the fixing.

[0038] Here, the support piece 9 is provided with a mounting hole 11 at one end corresponding to the horizontal shelf 3. The mounting hole 11 is used to fix the horizontal shelf 3 with a positioning block. The positioning block is fixed on the horizontal shelf 3. During installation, the positioning block is inserted into the mounting hole 11 to achieve the installation and fixation of the horizontal shelf 3.

[0039] To optimize the fit between slider 7 and T-slot 5 and ensure smooth sliding, slider 7 is rectangular, and slider 7 and T-slot 5 are in a clearance sliding fit. Of course, slider 7 can also be adjusted according to the specific shape of T-slot 5. To address the issue of wear on slider 7 and brake cam 8 during long-term sliding and clamping, leading to a shortened service life, both the side of slider 7 corresponding to the horizontal plate 3 and the contour surface of brake cam 8 are coated with an iron-based alloy coating.

[0040] Here, the thickness of the brake cam 8 is the same as the opening width of the T-slot 5. The brake cam 8 can extend out of the opening of the T-slot 5 or be completely retracted into the T-slot 5. Of course, the width of the support plate 9 is also the same as the opening width of the T-slot 5; that is, to ensure a tight fit between the brake cam 8, the support plate 9 and the opening of the T-slot 5, reducing loosening or shaking, thereby improving stability.

[0041] Here, in order to enhance the overall load-bearing capacity and overall support stability of the support plate 9, a connecting plate can be provided between adjacent support plates 9.

[0042] To avoid inconvenience caused by a rigid connection between the support plate 9 and the horizontal shelf 3, the support plate 9 and the horizontal shelf 3 can be hinged, such as by using a hinge structure. With this setting, the upward and downward movement of the horizontal shelf 3 will not affect the rotation of the support plate 9, thus allowing the support plate 9 to rotate effectively and achieve fixed or loosened adjustment.

[0043] The above scheme discloses the core components of the file organizer. Of course, depending on the needs of different scenarios, side panels or cabinet doors can be added, such as to make a file cabinet; crossbars for reinforcing the support rod 2 can also be set; these will not be elaborated here.

[0044] Example 2

[0045] Based on the above scheme, a torsion spring is provided between the brake cam 8 and the slider 7. The torsion spring causes the brake cam 8 to twist downwards toward the opening of the T-slot 5 and lock onto the T-slot 5. The torsion spring can be a single-strand straight-wound torsion spring, which is mounted on the connecting shaft 10 and its ends are connected to the slider 7 and the brake cam 8 respectively. Since the brake cam 8 is locked by gravity, the method of locking it by the weight of the horizontal shelf 3 pressing down on the support plate 9 when no documents are placed on it is unreliable and is prone to loosening and slippage due to external impact. To enhance the stability of the brake cam 8 under normal conditions, a torsion spring is provided to provide continuous torsional force so that the brake cam 8 remains locked under normal conditions.

[0046] When adjusting the height, the horizontal shelf 3 also needs to be raised. At this time, the support plate 9 drives the brake cam 8 to rotate upward against the torque of the torsion spring, so that the brake cam 8 separates from the inner wall of the T-slot 5, and the slider 7 can slide freely along the T-slot 5. When the shelf moves to the required height, the horizontal shelf 3 is released, and the torque of the torsion spring will drive the brake cam 8 to rotate automatically in the opposite direction, so that it is locked back into the T-slot 5, thus completing the height adjustment.

[0047] It is important to note that when raising the horizontal shelf 3, sufficient force must be applied to overcome the torque of the torsion spring. Insufficient force may prevent the brake cam 8 from fully disengaging, causing the slider 7 to become stuck. During adjustment, the horizontal shelf 3 should be kept under stable force to prevent excessive local friction between the brake cam 8 and the T-slot 5 due to uneven force on one side, which could affect the smoothness of sliding.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of the patent application of the present utility model. All equivalent changes, equivalent substitutions or modifications made within the technical spirit and principles indicated by the present utility model should be included within the scope of patent protection covered by the present utility model.
