Stretchable plastic turnover box

Abstract

This utility model belongs to the field of stretchable expansion technology for turnover boxes, specifically a stretchable plastic turnover box, including: a first turnover box frame, a stretching limiting component, and a cover plate removal component. The first turnover box frame has sliding grooves on both its front and back sides. This utility model achieves this by placing the cover plate on the upper surface of a second mounting frame, then pressing down on the pressure rod to move the second inclined ring downwards, widening the gap between the limiting blocks until it inserts into the lower end of the limiting blocks. A first return spring restores the gap between the limiting blocks, clamping and limiting the second inclined ring, thus connecting the cover plate. Pressing down on the pressure rod again causes the first inclined ring to engage with the lower end of the limiting blocks. Pulling down the pressure rod moves the first inclined ring downwards to contact the second inclined ring. At this point, the first inclined ring moves upwards, widening the gap between the limiting blocks, releasing the restriction on the second inclined ring, and allowing the cover plate to be removed. This achieves the effect of limiting the cover plate through pressing.

Description

Technical Field

[0001] This utility model belongs to the field of stretchable expansion technology of turnover boxes, specifically a stretchable plastic turnover box. Background Technology

[0002] Currently, distribution cabinets are widely used in various industrial production processes. They are the final stage equipment in the entire power distribution system, providing protection, monitoring, and control for the load. Some control devices inside the distribution cabinet need to be interconnected by cables.

[0003] In the existing technology, a stretchable plastic turnover box with announcement number CN222248121U is described. This application uses a pull-out plate and baffle structure to pull the pull-out plate out from the inside of the turnover box and then pull the baffle out from the outside of the turnover box to open it, forming a larger placement space. This allows for adjustment and change of the overall space of the turnover box, enabling rapid changes in the space of the turnover box to store more items.

[0004] However, in use, the cover plate is usually restricted by bolts. Multiple bolts need to be rotated during use, and it is not possible to quickly restrict the cover plate by simply pressing it. The multi-bolt restriction usually requires rotating and adjusting each one, which is cumbersome and time-consuming, inconvenient to use, and reduces the efficiency of operation. For this reason, we provide stretchable plastic turnover boxes. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problems of restricting the cover plate by pressing and preventing the second turnover box frame from sliding freely after stretching, a stretchable plastic turnover box is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] Stretchable plastic turnover boxes, including:

[0008] The first turnover box frame has sliding grooves on both the front and back sides, and a groove at the top. A second turnover box frame is inserted inside the first turnover box frame, and a baffle is fixedly installed on one side of the second turnover box frame. A pull groove is provided on one side of the baffle.

[0009] Preferred options also include:

[0010] A stretching limiting component is installed on the front of the second turnover box frame to limit the distance the turnover box has been stretched.

[0011] Preferably, the stretching limiting component includes:

[0012] A slider is bolted to the front of the second turnover box frame. The slider is partially adapted to the slide groove. A first mounting frame is fixedly installed on the front of the slider. Two square slots are opened on the back of the first mounting frame.

[0013] Preferably, the front of the first mounting frame is provided with a protective groove, and the inside of the protective groove is provided with two threaded holes. The inside of the threaded holes is connected with a fixing bolt, and the moving and fixing bolt is fixed by a limiting plate.

[0014] Preferred options also include:

[0015] A cover plate removal assembly is installed in a groove for quick removal of the cover plate.

[0016] Preferably, the cover plate removal assembly includes:

[0017] The second mounting frame is bolted into the groove. Two limiting frames are installed on the inner side wall of the second mounting frame. Each limiting frame has a limiting groove on both sides. A movable rod is provided inside the limiting groove. A first return spring is provided on the surface of the movable rod. One end of the first return spring is fixedly connected to the inner side wall of the limiting frame, and a limiting ring is fixedly installed on the other end of the first return spring.

[0018] Preferably, the limiting ring is fixedly connected to the movable rod, the other side of the limiting ring is in contact with the inner wall of the limiting frame, a limiting block is fixedly installed at one end of the movable rod, a cover plate is provided at the upper end of the second mounting frame, a handle is installed at the middle of the upper end of the cover plate, and round holes are opened on both sides of the upper end of the cover plate.

[0019] Preferably, a pressing rod is provided inside the circular hole, a second return spring is provided on the surface of the pressing rod, an insert rod is fixedly installed at the lower end of the pressing rod, a fixing ring is fixedly installed on the surface of the insert rod, a first inclined ring is sleeved on the surface of the insert rod, and a second inclined ring is fixedly installed at the lower end of the insert rod.

[0020] The beneficial effects of this utility model are:

[0021] The cover plate disassembly assembly of this utility model allows the cover plate to be placed on the upper surface of the second mounting frame. Pressing down on the pressure rod causes the second tilting ring to move downwards, clamping and restricting the second tilting ring at the lower end of the limiting block, thus connecting the cover plate. Pressing down on the pressure rod again causes the first tilting ring to engage with the lower end of the limiting block. Pulling down on the pressure rod causes the first tilting ring to move downwards and contact the second tilting ring. At this point, the upward movement of the first tilting ring widens the gap between the limiting blocks, releasing the restriction on the second tilting ring and allowing the cover plate to be removed. This achieves the purpose of restricting the cover plate by pressing, making it convenient and easy to use.

[0022] The stretching limiting component of this utility model, when the slider is moved to the desired position in the slide groove by the second turnover box frame, the rotating fixing bolt rotates and moves in the threaded hole, so that the limiting plate is tightly attached to the surface of the first turnover box frame, thereby limiting the second turnover box frame and preventing the second turnover box frame from sliding randomly after stretching.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Specific implementation examples are given below.

[0035] Example 1:

[0036] Please see Figures 1 to 5 This utility model provides a stretchable plastic turnover box, comprising:

[0037] The first turnover box frame 1 has sliding grooves 2 on both the front and back sides, and a groove at the upper end of the first turnover box frame 1. A second turnover box frame 3 is inserted inside the first turnover box frame 1. A baffle 4 is fixedly installed on one side of the second turnover box frame 3, and a pull groove is opened on one side of the baffle 4. A stretching limiting component 5 is installed on the front of the second turnover box frame 3 to limit the distance after the turnover box is stretched. A cover plate removal component 6 is installed in the groove for quick removal of the cover plate.

[0038] In this embodiment, firstly, the pull groove is pulled to pull the second turnover box frame 3 out from the first turnover box frame 1, increasing the internal storage space; secondly, the tension limiting component 5 is used to restrict the pulled-out second turnover box frame 3 to prevent it from sliding freely; then, the cover plate disassembly component 6 is used to restrict the cover plate 607 by pressing.

[0039] Example 2:

[0040] Based on Embodiment 1, a stretching limiting component 5 is further disclosed.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the stretching limiting component 5 includes:

[0042] The slider 501 is bolted to the front of the second turnover box frame 3. The slider 501 is partially adapted to the slide groove 2. The front of the slider 501 is fixedly mounted with a first mounting frame 502. The back of the first mounting frame 502 has two square grooves 503. The front of the first mounting frame 502 has a protective groove 504. The inside of the protective groove 504 has two threaded holes 505. The inside of the threaded holes 505 is threaded with a fixing bolt 506. The moving and fixed installation of the fixing bolt 506 is fixedly mounted with a limiting plate 507.

[0043] In this embodiment, when the second turnover box frame 3 drives the slider 501 to move to the desired position in the slide groove 2, the rotating fixing bolt 506 rotates and moves in the threaded hole 505, so that the limiting plate 507 is tightly attached to the surface of the first turnover box frame 1, which restricts the stretched second turnover box frame 3, thereby preventing the stretched second turnover box frame 3 from sliding at will.

[0044] Example 3:

[0045] Based on Embodiment 1, a cover plate disassembly assembly 6 is further disclosed.

[0046] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the cover plate removal assembly 6 includes:

[0047] A second mounting frame 601, bolted into a groove, has two limiting frames 602 mounted on its inner wall. Each limiting frame 602 has a limiting groove on both sides, inside which a movable rod 603 is installed. A first return spring 604 is mounted on the surface of the movable rod 603. One end of the first return spring 604 is fixedly connected to the inner wall of the limiting frame 602, and the other end is fixedly fitted with a limiting ring 605. The limiting ring 605 is fixedly connected to the movable rod 603, and the other side of the limiting ring 605 is flush with the inner wall of the limiting frame 602. The two parts are in contact with each other. One end of the movable rod 603 is fixedly installed with a limiting block 606. The upper end of the second mounting frame 601 is provided with a cover plate 607. A handle 608 is installed in the middle of the upper end of the cover plate 607. Circular holes 609 are opened on both sides of the upper end of the cover plate 607. A pressing rod 610 is provided inside the circular hole 609. A second return spring 611 is provided on the surface of the pressing rod 610. An insert rod is fixedly installed at the lower end of the pressing rod 610. A fixing ring 612 is fixedly installed on the surface of the insert rod. A first inclined ring 613 is sleeved on the surface of the insert rod. A second inclined ring 614 is fixedly installed at the lower end of the insert rod.

[0048] In this embodiment, the cover plate 607 is placed on the upper surface of the second mounting frame 601, and then the pressing rod 610 is pressed to move the second inclined ring 614 downward, widening the gap between the limiting blocks 606 until it is inserted into the lower end of the limiting blocks 606. The first return spring 604 restores the gap between the limiting blocks 606, clamping and restricting the second inclined ring 614, so that the cover plate 607 is connected. Then, the pressing rod 610 is pressed again to make the first inclined ring 613 snap into the lower end of the limiting block 606. When the pressing rod 610 is pulled, the first inclined ring 613 moves downward and contacts the second inclined ring 614. At this time, the first inclined ring 613 moves upward to widen the gap between the limiting blocks 606, releasing the restriction on the second inclined ring 614, and the cover plate 607 can be taken out. Thus, the cover plate 607 is restricted by pressing, which is convenient to use and simple to operate.
