Description

Technical Field

[0001] The utility model relates to a storage rack, in particular to a storage rack with adjustable telescopic degree. Background Art

[0002] The storage rack is a commonly used shelf for placing sundries. As the application of storage racks in family life becomes more and more extensive, the design of storage racks becomes more and more important. In order to realize the foldable design of the storage rack and reduce the occupied space when not in use, the utility model patent CN220512456U discloses a storage rack, including a base and a load-bearing net, and the base is provided with a winding shaft for winding up the load-bearing net; the two sides of the base are also provided with support members; one end of the support member is rotatably connected to the base, and the other end of the support member is rotatably connected to the provided pull plate. When the pull plate is pulled, the load-bearing net is spread out, and at this time, the support members on both sides of the base can support the pull plate while preventing the load-bearing net from bending downward due to the load. Since the load-bearing net is rolled up by the winding shaft, the space occupied by the device can be reduced when not in use. However, during use, it was found that although the storage rack can be folded, it has only one state when opened, that is, fully unfolded. This is mainly because the design of the support member is unreasonable. The support member is a hinge rotation connection structure. Since there is a reset member (that is, a coil spring structure) that has a certain winding force when the carrying net is pulled open, the hinge structure cannot provide supporting force when it is not fully opened. Therefore, the carrying net can only be used when the support member is fully opened, and it cannot be reasonably extended and adjusted according to the size of the items placed by the user. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to provide a storage rack with adjustable telescopic degree.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a storage rack with adjustable telescopic degree, comprising a base and a pull plate arranged on one side of the base, a winding support net is fixed to the inner side of the pull plate, the other end of the winding support net is fixedly connected to the winding shaft in the base, the winding shaft is arranged in the base through a winding spring structure, and a plurality of telescopic rods for supporting the winding support net are arranged under the winding support net, and the two ends of each telescopic rod are respectively fixedly connected to the base and the pull plate.

[0005] Furthermore, in order to ensure that the winding support net does not rebound after being stretched, the sum of the damping of all telescopic rods is greater than the winding force of the coil spring structure when the telescopic rods are fully extended, and a certain limiting effect is played by the damping of the telescopic rods.

[0006] Furthermore, a horizontal hanging rod is fixed to the bottom edge of the pull plate pair.

[0007] Furthermore, a slot structure with a barbed hook-shaped cross section is provided on the inner side surface of the pull plate, and one end of the winding support net is wound on the fixed clamping rod, and the fixed clamping rod is clamped in the slot structure.

[0008] Furthermore, a stop edge bent toward the base is provided at the top end of the pull plate, and the pull plate is formed in one piece.

[0009] Furthermore, a slot structure with a G-shaped cross section is provided at the bottom edge of the pull plate, and both ends of the suspension rod are bent upward and then inward, so that the bent parts of both ends of the suspension rod are inserted into the slot structure.

[0010] Furthermore, there are at least two telescopic rods between the base and the pull plate, and each telescopic rod has at least three-section telescopic structures.

[0011] Furthermore, detachable plugs are fixed at both ends of the base, and the coil spring structures at both ends of the winding shaft are respectively fixed on the inner sides of the plugs at both ends.

[0012] Furthermore, a plurality of hooks are arranged at intervals on the bottom of the base.

[0013] The utility model has the following advantages: the utility model optimizes the telescopic support structure, which can make the winding support net stay at an arbitrarily extended position of the telescopic rod, so that the user can make reasonable telescopic adjustments according to the size of the article; in addition, the winding support net is often pulled out with force at one end, that is, the end fixedly connected to the pull plate, and is fixed by the card slot structure and the fixed card rod, which not only makes the pulled-out end of the winding support net more evenly fixed and firmly fixed, but also effectively prevents the winding support net from being torn due to uneven fixation; the pull plate forms a structure that is not easy to bend and deform, ensuring that the overall support is more firmly when the pull plate is pulled out.

[0019] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. In the description of the utility model, it should be noted that the orientation or position relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The present embodiment is described in detail below with reference to the accompanying drawings:

[0022] This embodiment provides a shelf with adjustable telescopic degree. Please refer to the attached drawings in the specification for details. Figure 1-5 .

[0023] like Figure 1-5 As shown, a storage rack with adjustable telescopic degree comprises a base 1 and a pull plate 2 arranged on one side of the base 1, a winding support net 3 is fixed to the inner side of the pull plate 2, the other end of the winding support net 3 is fixedly connected to the winding shaft 4 in the base 1, the winding shaft 4 is arranged in the base 1 through a coil spring structure, a plurality of telescopic rods 5 for supporting the winding support net 3 are arranged below the winding support net 3, at least two telescopic rods 5 are arranged between the base 1 and the pull plate 2, each telescopic rod 5 has at least three-section telescopic structure, such as eight sections, so that the telescopic rod after being pulled out is as much as 5 times the original length, so that the storage rack of the utility model is more compact when contracted and has a larger supporting surface when pulled open, the two ends of each telescopic rod 5 are respectively fixedly connected to the base 1 and the pull plate 2, such as by plugging, bolts and screws, strong glue bonding and fixing blocks, as long as the two ends of each telescopic rod 5 can be firmly fixed to meet daily use.

[0024] The sum of the damping of all telescopic rods 5 is greater than the winding force of the coil spring structure when the telescopic rod 5 is in a fully extended state. In this way, it can be ensured that when the telescopic rod 5 is extended to any length, the resistance formed by its damping is greater than the winding force of the coil spring structure, ensuring that the winding support net 3 is pulled out and the telescopic rod 5 does not retract after being extended. Furthermore, the umbrella rod structure similar to the current telescopic umbrella has an elastic protrusion structure at the telescopic part, which can fully meet the extension and retraction of the telescopic rod 5.

[0025] In order to facilitate the installation of the winding support net 3, the inner side surface of the pull plate 2 is provided with a slot structure 7 with a barbed hook cross-section. One end of the winding support net 3 is wound on the fixed clamping rod 8, and the fixed clamping rod 8 is clamped in the slot structure 7. In this way, the entire edge of one end of the winding support net 3 can be fixed, which not only makes the fixation more firm, but also has a good supporting effect on the items on the winding support net 3, and is easy to install.

[0026] The top of the pull plate 2 is provided with a stopper 9 bent toward the base 1. The pull plate 2 is formed in one piece. The stopper 9 plays a role similar to a handle, which is convenient for pulling out the pull plate 2 when using the winding support net 3. The two ends of the base 1 are fixed with detachable plugs 11, and the coil spring structures at both ends of the winding shaft 4 are respectively fixed to the inner side of the plugs 11 at both ends. For easy installation and disassembly, the bottom edges of the pull plates 2 are fixed with horizontal hanging rods 6, and the bottom of the base 1 is provided with multiple hooks 12 at intervals, which is convenient for hanging other items.

[0027] A slot structure 10 with a G-shaped cross-section is provided on the bottom edge of the pull plate 2. The two ends of the hanging rod 6 are bent upward and then inward, so that the bent parts at both ends of the hanging rod 6 are inserted into the slot structure 10. Similarly, it is convenient to insert and fix the hanging rod 6, and the installation is faster. In addition, the slot structure 10, the slot structure 7 and the retaining edge 9 also make the entire pull plate 2 play a role in strengthening the pull plate 2, so that the pull plate 2 forms a structure that is not easy to bend and deform, ensuring that the overall support is more firm when the pull plate 2 is pulled out.

[0028] The working principle of the utility model is as follows: when the winding support net 3 needs to be pulled out for use, the pull plate 2 is pulled to overcome the damping of the telescopic rod 5 and the winding force of the coil spring structure, so that the pull plate 2 drives the winding support net 3 to be pulled out. After being pulled out, since the sum of the damping of all the telescopic rods 5 is greater than the winding force of the coil spring structure when the telescopic rod 5 is fully extended, the telescopic rod 5 can be stopped at any extended position through the damping of the telescopic rod 5, so that the winding support net 3 can be stopped at any extended position of the telescopic rod 5, which is convenient for users to perform reasonable telescopic adjustment according to the size of the items.

[0029] In addition, one end of the winding support net 3, that is, the end fixedly connected to the pull plate 2, is often pulled out with force, and is fixed by the slot structure 7 and the fixed clamping rod 8, which not only makes the pulled-out end of the winding support net 3 more evenly fixed and firmly fixed, but also effectively prevents the winding support net 3 from being torn due to uneven fixation; the pull plate 2 is provided with an external slot structure 10, a slot structure 7 and a stop edge 9, so that the pull plate 2 forms a structure that is not easy to bend and deform, thereby ensuring that the overall support is more firmly when the pull plate 2 is pulled out.

[0030] Of course, the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
