Description

Technical Field

[0001] This utility model relates to the field of home appliance security inspection technology, and in particular to an anti-pinch follow-up device for refrigerator security inspection lines. Background Technology

[0002] During the production process of refrigerators, electrical safety aspects (such as grounding measures, overload protection, leakage current, etc.) need to be tested. In order to improve testing efficiency, most home appliance manufacturers now adopt online testing methods, that is, relevant safety tests are carried out while the refrigerator is running on the production line.

[0003] During the testing process, the refrigerator needs to be powered on. As the refrigerator moves along the production line, its power cord, plug, or other foreign objects may get stuck in the seams between the chain plates of the production line, which may cause problems such as the power cord being pinched or the line being damaged. In severe cases, it may even drag the refrigerator over.

[0004] Therefore, it is necessary to design a follow-up device that can avoid wire clamping in order to facilitate the safety inspection of refrigerators. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model discloses an anti-pinch follow-up device for refrigerator security inspection lines, comprising a frame, a chain, a drive motor, junction boxes, sockets, and a plug separation assembly. Each end of the frame has a set of sprockets, and the chain is driven by these sprockets. The drive motor is located at one end of the frame and is driven by one of the sprockets. Several junction boxes are sequentially arranged on the chain, and a socket is provided between every few junction boxes, with the socket located inside each junction box. The plug separation assembly is driven by the sockets. The seams between adjacent junction boxes are covered by a covering assembly. Further, the covering assembly includes a rubber pad and a first bolt. One side of the rubber pad is attached to the top of the junction box by the first bolt, and the other side of the rubber pad covers the top of the adjacent junction box.

[0006] Furthermore, the covering assembly includes a flexible cloth, a pressure plate, and a second bolt. A flexible cloth is provided above the junction box between two adjacent sockets, and the two ends of the flexible cloth are respectively connected to the side of the junction box through the pressure plate and the second bolt.

[0007] Furthermore, the plug separation assembly includes a top plate, a guide shaft, a roller, and a wedge block. The top plate is disposed above the socket. The guide shaft passes through the socket longitudinally and is connected to the top plate at its upper end and rotatably connected to the roller at its lower end. The wedge block is fixedly disposed on the frame with its wedge surface facing upward.

[0008] Furthermore, a spring is sleeved on the outside of the guide shaft between the top plate and the socket, and the two ends of the spring are respectively connected to the bottom of the top plate and the top of the socket.

[0009] Furthermore, a power supply board is located inside the frame below the socket, and multiple brushes are connected to the bottom of the socket via conductive blocks, with the brushes making slidable contact with the power supply board.

[0010] Furthermore, the main shaft of the drive motor is provided with a drive sprocket, and a driven sprocket is coaxially provided on one side of the sprocket. The drive sprocket and the driven sprocket are connected by a transmission chain.

[0011] Furthermore, the chain and frame are provided with protective covers on their outer sides.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a drive motor and chain to drive the socket to rotate in a cycle following the refrigerator detection line. The refrigerator plug is plugged into the socket. When the socket moves above the plug separation component, the plug separation component automatically lifts the plug, separating it from the socket. The seam between the junction boxes is covered by a cover component to prevent power cords or other foreign objects from entering the seam, thereby ensuring the safe operation of the security inspection line.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0027] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0028] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. 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 a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Example 1:

[0030] like Figure 1-2As shown, the anti-pinch follow-up device for the refrigerator security inspection line in this embodiment includes a frame 1, a chain 2, a drive motor 3, a junction box 4, a socket 5, and a plug separation assembly. Each end of the frame 1 is provided with a set of sprockets 6. The chain 2 is connected to the sprockets 6 at both ends. The drive motor 3 is located at one end of the frame 1 and is connected to one of the sprockets 6. The specific transmission connection method is as follows: the main shaft of the drive motor 3 is provided with a drive sprocket 7, and a driven sprocket 8 is coaxially provided on one side of the sprocket 6. The drive sprocket 7 and the driven sprocket 8 are connected by a transmission chain 9. Thus, through the cooperation of the drive motor 3, the drive sprocket 7, the driven sprocket 8, and the sprocket 6, the chain 2 can be driven to rotate.

[0031] A number of junction boxes 4 are arranged sequentially on the chain 2, and a socket 5 is provided between each number of junction boxes 4, and the socket 5 is located inside the junction box 4.

[0032] A protective cover 10 is provided on the outside of the chain 2 and the frame 1 to cover and protect the chain 2 and the frame 1, and to prevent foreign objects from entering the device.

[0033] The plug separation assembly is connected to the socket 5, and the seam between adjacent junction boxes 4 is covered by a cover assembly.

[0034] like Figure 3 As shown, the covering assembly includes a rubber pad 11 and a first bolt 12. One side of the rubber pad 11 is mounted on the top of the junction box 4 via the first bolt 12, and the other side of the rubber pad 11 covers the top of the adjacent junction box 4. The rubber pad 11 can effectively cover the seam between two adjacent junction boxes 4, preventing power cords, plugs, or other foreign objects from entering the seam and causing safety hazards. Furthermore, when the junction box 4 rotates to the end of the chain 2 for reversal, the rubber pad 11 will automatically separate from the junction box 4, and after the reversal is completed, it will cover the seam between the junction boxes 4 again.

[0035] like Figure 4-5 As shown, the plug separation assembly includes a top plate 13, a guide shaft 14, a roller 15, and a wedge block 16. The top plate 13 is positioned above the socket 5. The guide shaft 14 passes through the socket 5 longitudinally and is connected to the top plate 13 at its upper end and rotatably connected to the roller 15 at its lower end. The wedge block 16 is fixedly mounted on the frame 1 with its wedge surface facing upward.

[0036] A spring 17 is sleeved on the outside of the guide shaft 14 between the top plate 13 and the socket 5. The two ends of the spring 17 are connected to the bottom of the top plate 13 and the top of the socket 5, respectively.

[0037] When the roller 15 contacts the wedge block 16, the guide shaft 14 is gradually lifted upwards, and the top plate 13 is also lifted upwards, thereby causing the plug inserted into the socket 5 to fall off, realizing the automatic separation of the plug from the socket 5.

[0038] like Figure 6As shown, a power supply board 18 is located inside the frame 1 below the socket 5. Multiple brushes 20 are connected to the bottom of the socket 5 through conductive blocks 19. The brushes 20 slide in contact with the power supply board 18, thus enabling the power supply to the socket 5 during the operation of the device.

[0039] Example 2:

[0040] like Figure 7-8 As shown, the covering assembly in this embodiment includes a flexible cloth 21, a pressure plate 22, and a second bolt 23. A flexible cloth 21 is provided above each junction box 4 between two adjacent sockets 5. The two ends of the flexible cloth 21 are connected to the sides of the junction box 4 via the pressure plate 22 and the second bolt 23, respectively. The flexible cloth 21 can be made of soft and elastic materials such as nylon, polyester fiber, or spandex to meet the operational requirements of the junction box 4 and the sockets 5.

[0041] The chain 2 and the frame 1 are all shielded by protective covers 10 on the front, back, left and right sides, so as to effectively protect the chain 2 and the frame 1 and prevent foreign objects from entering the device.

[0042] The other structures in this embodiment are similar to those in Embodiment 1, and will not be described again here.

[0043] When this utility model is in operation, the refrigerator runs along the security inspection line on one side of the device. During the inspection, the staff first plugs the refrigerator into the socket 5 at one end of the frame 1 to supply power to the refrigerator, thus enabling the safety inspection of the refrigerator during operation.

[0044] When socket 5 moves to the other end of frame 1, the detection is completed, and the refrigerator can be powered off. When roller 15 contacts wedge block 16, guide shaft 14 and top plate 13 are pushed upward, causing the plug in socket 5 to fall off, thus powering off the refrigerator.

[0045] During the inspection, the seams between junction boxes 4 are covered by a covering component and the surrounding area is covered by a protective cover 10, preventing power cords, plugs or other foreign objects from entering the seams, thus ensuring the safe operation of the security inspection line.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
