Description

Technical Field

[0001] The invention relates to the technical field of compact shelving parts and components, in particular to a compact shelving standard insert that is telescopically adjustable. Background Art

[0002] The label insert in the compact shelving is a crucial component. Its main function is to provide clear identification and classification to help users quickly locate the required information. Label inserts are usually installed on each layer. By displaying specific item categories or storage information, they greatly improve the search efficiency and avoid confusion and misplacement of items. From a structural point of view, label inserts generally consist of three parts: a base, a slot and a label. The base is the part fixed to the edge or side of the shelf, usually made of durable materials to ensure its stability and durability. The slot is the main functional area of ​​the label insert, designed as an opening that can be easily inserted and removed, and can effectively accommodate labels or cards. Labels are paper or plastic cards with information or classifications written on them, which are convenient for users to identify and use. Some label inserts may be equipped with transparent protective covers to further protect the labels from damage; for example, the stable storage archive compact rack disclosed in the authorization announcement number CN210989029U includes a rack guide rail, on which a compact rack is arranged in sequence, and the rectangular space of the compact rack is divided into a plurality of storage compartments; the compact rack is provided with storage baffle rods at the lower part of the outer port of each layer of the storage compartment, respectively, and at least one blocking box sleeve is slidably installed on the storage baffle rod corresponding to each of the storage compartments, and a blocking box baffle is fixedly provided on the blocking box sleeve, and a plurality of baffle slots are respectively provided on the transverse partition plate and the bottom plate of the compact rack, and an inserting portion is provided on the blocking box baffle, and the archive box at the end Inserting the blocking box baffle into the nearby baffle slot can effectively block the file box, reduce the occurrence of file box tilting, tipping, and file box falling. In order to facilitate users to timely understand the content of each file box in this technical solution, it is necessary to use a label plug for the installation of the indicator label. However, with the rapid development of the structure and function of the compact shelving, the shelves inside the compact shelving are set to slide up and down and slide left and right to adjust the spacing. At this time, the fixed-length structure setting of the label plug makes it difficult to flexibly and stably install it between the upper and lower shelves. That is, when the user adjusts the shelf according to the actual height of the stored items, the fixed-length label plug may no longer accurately identify the items on that layer. If the height of the shelf changes greatly, the originally designed label plug will appear too long or too short, resulting in unclear information display, and even the need to redesign and replace the label plug, which is very inconvenient in actual operation. At the same time, once the fixed-length label plug is installed in a certain position, if the shelf slides up and down, the fixity of the label plug will also be affected, resulting in problems such as loosening, tilting or falling off during use. This instability not only affects the readability of information, but may also cause damage to the label and affect the overall storage management effect. Summary of the invention

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1, by Figures 1 to 4 The present invention comprises an external square mouth tube 1, both ends of the internal part of the external square mouth tube 1 are threadedly installed with external threaded struts 2 that penetrate the external part of the external square mouth tube 1, the ends of the external threaded struts 2 are used to contact with the compact shelving layers, and elastic feedback structures are arranged at the positions of the two ends of the internal part of the external square mouth tube 1, and the force of the elastic feedback structure is proportional to the screwing distance of the external threaded struts 2, and the outer wall surfaces of the two ends of the external square mouth tube 1 are arranged with multi-wheel straightening guide structures 5 for contacting the outer wall of the external threaded struts 2. The structural design of the multi-wheel straightening guide structure 5 also enables the external threaded struts 2 to maintain a good guiding effect whether moving upward or downward during the adjustment process, ensuring that it will not lose balance due to adjustment; The fan-shaped notch 7 is arranged on the outer wall of one side of the external thread support rod 2. An elastic self-expanding label connector 8 is arranged inside the fan-shaped notch 7. The elastic self-expanding label connector 8 is used for installing a note card. The elastic self-expanding label connector 8 automatically moves after the external thread support rod 2 is removed from the outer square tube 1. A rubber disc 6 is fixed to one end of the external threaded support rod 2 away from the external square mouth tube 1, and a round chamfer is provided at the edge of the upper surface of the rubber disc 6, so that the rubber disc 6 reduces the abutment damage between the layer plates caused by the external threaded support rod 2.

[0019] Embodiment 2, based on embodiment 1, Figure 5 , Figure 6 and Figure 7 It is given that the inner wall of the external square tube 1 is provided with an internal thread groove 101 extending toward both ends, and the external thread support rod 2 is composed of an external thread bottom column 201, a connecting rod 202 and an annular retaining edge 203. The external thread bottom column 201 is threadedly installed at the internal thread groove 101, and the connecting rod 202 is fixed at the center position of the end of the external thread bottom column 201. The end of the connecting rod 202 penetrates to the outside of the external square tube 1, and the annular retaining edge 203 is integrally formed at one end of the surface of the connecting rod 202. When the user manually screws the two external thread support rods 2, the external thread bottom column 201 cooperates with the internal thread groove 101 on the inner wall of the external square tube 1, and the external square tube 1 and the external thread support rod 2 can be adjusted in length by rotation to adapt to the distance between different layer plates; The elastic feedback structure includes a square baffle 3 integrally formed at one end of the outer square mouth tube 1 and a force spring 4 fixed on both sides of the bottom end of the square baffle 3, the bottom end of the force spring 4 is in contact with the upper surface of the annular rib 203, the outer diameter of the annular rib 203 is greater than the inner diameter of the square baffle 3, and the inner diameter of the square baffle 3 is equal to the outer diameter of the connecting rod 202. When the external threaded bottom column 201, the connecting rod 202, and the annular rib 203 rotate upward, the force spring 4 located between the square baffle 3 and the annular rib 203 is squeezed, and the elastic force generated by the force spring 4 is proportional to the upward movement distance of the annular rib 203, that is, the longer the moving distance of the external threaded bottom column 201 and the connecting rod 202 is, the greater the user's twisting resistance is, so that force feedback can be provided at all times when the external threaded support rod 2 is screwed out, reminding the user of the current screwing distance, which can effectively prevent the user from negligence during operation and improve the safety and accuracy of the standard insertion operation; The multi-wheel straightening guide structure 5 includes a straight plate 501 bolted and fixed to the front, rear, left and right outer walls of the outer square mouth tube 1, a rotating shaft 502 rotatably installed at the ends between two adjacent straight plates 501, and a pulley 503 fixed at one end of the rotating shaft 502. The outer wall of the outer square mouth tube 1 is provided with a hollow groove 504 for the pulley 503 to penetrate into the inner part of the outer square mouth tube 1. The pulley 503 contacts the outer wall surface of the annular retaining edge 203. The outer square mouth tube 1, the external threaded support rod 2 and the straight plate 501 are all made of aluminum alloy. The components are made of gold material. When the external threaded support rod 2 rotates toward the outside of the external square mouth tube 1, the outer wall surface of the connecting rod 202 contacts the pulley 503, and the hollow groove 504 on the outer wall of the external square mouth tube 1 allows the pulley 503 to enter the interior of the external square mouth tube 1. When the external threaded support rod 2 rotates in the external square mouth tube 1, the design of the pulley 503 and the rotating shaft 502 can reduce the friction force of the external threaded support rod 2 to move out, making the movement of the external threaded support rod 2 smoother and reducing the risk of tilting due to friction.

[0020] Embodiment 3, based on embodiment 2, Figure 8 It is given that the elastic self-expanding label connector 8 includes a hollow shaft 801 fixed inside the fan-shaped notch 7, curved arms 802 fixed at both ends of the surface of the hollow shaft 801, and a flat-mouthed stopper 804 sleeved on the hollow shaft 801, an inner concave hole 204 for the end of the curved arm 802 to enter is provided on one side outer wall of the annular retaining edge 203, torsion springs 805 are installed on the upper and lower surfaces of the hollow shaft 801 of the flat-mouthed stopper 804, a reinforced column 803 is fixed between two adjacent curved arms 802, a stopper rod 806 is provided at one end of the flat-mouthed stopper 804, a protruding portion at one end of the torsion spring 805 abuts against an outer wall of one side of the reinforced column 803, and a protruding portion at the other end of the torsion spring 805 abuts against an outer wall of one side of the stopper rod 806; The hollow shaft 801 is fixedly installed in the fan-shaped notch 7, and the end of the curved arm 802 away from the hollow shaft 801 extends to the inner concave hole 204 and is fixed. When all the components of the elastic self-expanding label connector 8 are removed from the outer square tube 1, since the flat mouth stopper 804 loses the blocking restriction of the inner surface of the outer square tube 1, the torsion spring 805 gradually recovers to the initial shape from the compressed deformation state, that is, the torsion spring 805 forces the flat mouth stopper 804 to deflect around the hollow shaft 801 until it is unfolded, and the user can stick the label card to be used on the flat surface of the flat mouth stopper 804 by bonding; A slot 8041 is provided on the outer wall of the flat stopper 804 away from the hollow shaft 801. For a label card in the form of a hard card, the side of the hard label card is slid and inserted into the slot 8041 until the hard label card is fully inserted and stabilized. The simple installation and removal method allows employees to quickly complete label replacement, thereby reducing time waste caused by improper label management. When the user does not use the label insert, the user presses the elastic self-expanding label connector 8 back into the fan-shaped notch 7, and the external threaded support rod 2 can be normally screwed and immersed in the external square tube 1 for easy storage and next use.

[0021] When the embodiment of the present application is in use, first, the external square tube 1 serves as a support for the entire marking structure, which can accommodate two externally threaded struts 2 and provide a firm fixation, and the rectangular design of the external square tube 1 has excellent stability, so that it can be firmly fixed between the two shelves and provide necessary support. The user ensures that the external square tube 1 and its accessories are not damaged, checks whether the externally threaded struts 2, the elastic feedback structure and the multi-wheel straightening guide structure 5 are installed in place, and ensures that all components are clean and free of debris so that subsequent operations can be carried out smoothly. Then the user places the marking in a vertical posture between the upper and lower shelves of the compact shelving, and rotates the externally threaded struts 2 according to the specific height between the two shelves to adjust the combined length between the external square tube 1. The externally threaded struts 2 can be shortened by rotating clockwise, and vice versa. When adjusting, refer to the obstruction indication of the reverse force of the elastic feedback structure to ensure that the externally threaded struts 2 reach the expected screwing distance. The user applies appropriate screwing pressure. In this process, the multi-wheel straightening guide structure 5 will help The external threaded support rod 2 is used to help the external threaded support rod 2 to remain upright and prevent it from tilting. When the external threaded support rod 2 reaches the predetermined height, the user needs to continue rotating until the top of the external threaded support rod 2 is firmly against the shelf of the compact shelving. This step is crucial and determines the stability of the label. Appropriate abutment pressure will help ensure the stable installation of the external threaded support rod 2 and avoid loosening during subsequent use. Once the external threaded support rod 2 is firmly installed, the elastic self-expanding label connector 8 and the external threaded support rod 2 are moved out of the external square mouth tube 1, and the elastic self-expanding label connector 8 loses the obstruction of the inner wall of the external square mouth tube 1, the elastic self-expanding label connector 8 will automatically expand from the fan-shaped notch 7. The user can install a note card on the expanded elastic self-expanding label connector 8 to clearly mark the file content in the area. After completing the above steps, the user should check the stability of the label, gently shake the external square mouth tube 1 and the external threaded support rod 2 to ensure that it will not loosen, and at the same time confirm that the contact between the external threaded support rod 2 and the shelf is tight to ensure the safety of the entire structure.
