Detailed implementation method

[0019] Next, in combination with the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Refer to Figures 1-6 , a track groove protection device for a compact shelving unit, includes a spring automatic retractor 4. The spring automatic retractor 4 is composed of a housing retractable end 40, a housing main body 41, a protection strip 42, a limit block 43 and a spring 411. Connecting rods 410 are installed on the corresponding two sides of the housing main body 41. A spring 411 is installed on the connecting rod 410. A protection strip 42 is installed on the spring 411. The protection strip 42 is located on the top of the slide rail 2.

[0021] Furthermore, it also includes a slide rail 2. A slider 3 is slidably connected to the slide rail 2. A compact shelving unit 1 is installed on the slider 3. One slider 3 is installed at each of the four corners at the bottom of the compact shelving unit 1; The compact shelving unit 1 is divided into an electric compact shelving unit and a manual compact shelving unit. It mainly equally spaces and combines the filing cabinets on the compact shelving unit 1, so that it can greatly save the floor space. Since it belongs to the prior art, its working principle will not be elaborated here too much.

[0022] Furthermore, the housing main body 41 is installed on multiple sliders 3. The top surface of the housing retractable end 40 and the top surface of the slide rail 2 are on the same horizontal line.

[0023] Further, the width of the housing retractable end 40 is less than the width of the housing main body 41 by 3 mm to 4 mm. Its main function is to limit the sliding bar 420 in the sliding groove 21. If the width of the housing retractable end 40 is set to be the same as the width of the housing main body 41, then the total width of the housing main body placement groove 20 and the sliding bar sliding groove 21 will surely be less than the width of the housing retractable end 40, that is, the sliding bar sliding groove 21 will not be able to play the role of connecting the housing main body placement groove 20 and limiting. The sliding bar 420 is installed on the corresponding two side surfaces of the protective strip 42, and the total width of the protective strip 42 and the sliding bar 420 is the same as the width of the housing retractable end 40.

[0024] Further, sliding bar sliding grooves 21 and housing main body placement grooves 20 are respectively formed in the corresponding two sides of the slide rail 2 from top to bottom. The housing main body 41 is placed in the sliding bar sliding groove 21, and the sliding bar 420 is slidably connected to the sliding bar sliding groove 21.

[0025] Further, a limiting block 43 is installed at one end of the protective strip 42. The limiting block 43 is installed on an adjacent slider 3. Here, the slider 3 is a slider 3 that is relatively far away from the adjacent one, that is, the slider 3 adjacent on the filing cabinets on two adjacent compact shelves 1; the limiting blocks 43 on two of the spring retractors 4 are installed on one side of the slide rail 2, that is, the left two spring retractors 4 shown in the attached drawings of the specification Figure 3 and Figure 1 The internal structural components of the spring retractor 4 are not all disclosed in this application document. Its internal structure is the same as that of the tape measure on the current market. The protective strip is retracted and released through the retraction and release of the spring 411. Since it belongs to the prior art, it will not be elaborated here too much.

[0026] The usage method and advantages of the present utility model: When the DC motor that is convenient for installation and fixation is in use, the working process is as follows:

[0027] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown in the figure, when using this device, when the filing cabinets on the compact filing cabinet 1 are gathered, the spring automatic retractor 4 installed on the slider 3 works, and its working state is as follows: when the slider 3 on the filing cabinet slides along the slide rail 2, the spring 411 in the spring automatic retractor 4 pays out the line. Since one end is restricted by the limit block 43, at the same time, the length of the protective strip 42 increases, so that it covers the slide rail 2. As the filing cabinets are gathered, the part of the slide rail 2 exposed to the air is covered, which can not only prevent dust from getting in, but also prevent small objects from directly falling into the slide rail 2. On the one hand, it is easy to block the sliding of the slider 3 and cause damage to the compact rack. On the other hand, it also avoids the inconvenience for users to search for and take items in a narrow space. The working principle of the spring automatic retractor 4 is the same as that of the tape measure currently in use, and its working principle and internal structure will not be elaborated here;

[0028] At the same time, the sliding strip 420 on the protective strip 42 slides in the sliding strip chute 21, which can avoid the trouble of the protective strip 42 being sunken by the dropped small objects, and has the advantages of limiting and pulling the protective strip 42 by limiting the sliding strip 420 in the sliding strip chute 21.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
