[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-8 The technical solution provided by this utility model is as follows:

[0028] Example 1:

[0029] In this embodiment, a mobile phone back cover strength testing mechanism includes a body. An electronic winding reel is provided on the top of the outer wall of the body. A connecting rope is installed around the inner wall of the electronic winding reel. An electromagnetic plate is provided on the outer wall of the connecting rope. The electromagnetic plate can be separated when the power is off and will be attracted when the power is restored. A hook is connected to one end of the connecting rope. A bottom hanging rope is provided on the outer wall of the hook. One end of the bottom hanging rope is connected to a base plate. A sleeve is installed on the bottom of the outer wall of the base plate. A telescopic rod is installed on the inner wall of the sleeve. A spring is installed around the outer wall of the telescopic rod. A base block is connected to one end of the telescopic rod. A locking block is provided on the outer wall of the base block. A pressing spring is installed on one end of the locking block. A strength testing pen is installed on the inner wall of the base block.

[0030] In this embodiment, a chuck is installed on the top of the base plate, and hanging rods are provided on both sides of the outer wall of the chuck. A counterweight is provided on the outer wall of the hanging rod, and a locking bolt is movably installed on the top of the counterweight.

[0031] In this embodiment, a placement platform is installed at the bottom of the inner wall of the machine body, a detection adjustment light is installed on one side of the placement platform, and a sealing plate is provided at the bottom of the outer wall of the machine body.

[0032] In this embodiment, the inner wall of the sleeve is provided with a cavity, which is L-shaped. The cavity of the sleeve allows the locking block to move or be fixed within the cavity.

[0033] In this embodiment, the three-dimensional view of the card block is cylindrical, and the diameter of the outer wall of the card block is adapted to the diameter of the sleeve cavity, so that the card block can slide inside the sleeve cavity.

[0034] In this embodiment, the outer wall of the base block is provided with an annular protrusion, and the inner wall of the annular protrusion of the base block is provided with a cavity. The strength test pen is installed on the inner wall of the annular protrusion of the base block, and the user needs to hold the base block to complete the subsequent adjustment operation.

[0035] In this embodiment, the inner wall of the base block is provided with a cavity, and a pressing spring is installed in the cavity of the base block and connected to one end of the locking block. The user can press the locking block to cause the pressing spring connected to one end of the locking block to retract, thereby causing the locking block to retract into the cavity of the base block.

[0036] Working principle: When in use, the user first places the phone on the sealing plate, then cuts off the power to the electromagnetic plate, which then separates. The hook then pulls the bottom hanging rope down, and the bottom plate connected to one end of the bottom hanging rope also falls. When the bottom plate falls, the strength testing pen will perform a pressure test on the phone back cover on the sealing plate. During the test, since the detection adjustment light is parallel to the placement platform, the light emitted by the detection adjustment light can make the phone back cover on the placement platform show whether there is a dent, thereby further judging the strength of the phone back cover.

[0037] Secondly, if the user needs to test the local pressure on the back cover of the phone, the user only needs to hold the annular protrusion on the bottom block and rotate the bottom block. When the bottom block rotates, the locking block will move to one side of the sleeve cavity. At this time, the user presses the locking block to cause the pressing spring connected to one end of the locking block to contract, thereby causing the locking block to contract into the cavity of the bottom block. Finally, the user holds the bottom block and pushes it against the inner wall of the sleeve, causing the pressure test pen to contract into the cavity of the sleeve. Then, the user releases the locking block, causing the pressing spring to drive the locking block to reset. Finally, the user holds the locking block and rotates it to the other side of the sleeve cavity to lock the pressure test pen. By repeating this operation multiple times, an independent pressure test pen can be retained. In this way, during pressure testing, the remaining pressure test pen can be used to perform local pressure testing on the back cover of the phone, either individually or in a localized manner.

[0038] Finally, the user can add a weight to the hanging rod on the outer wall of the chuck and then fix it by rotating the locking bolt. The increased weight of the chuck will increase the pressure of the strength testing pen, thereby controlling the downward pressure of the strength testing pen and testing the strength of the phone back cover under different pressures. The user then reconnects the electromagnetic plate to power and starts the electronic winding reel. After the electronic winding reel starts, it will rotate to lower the connecting rope. When the connecting rope is lowered, the electromagnetic plate will re-contact and attract the rope. At this time, the user can control the electronic winding reel to rewind the connecting rope. This completes the practical work.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
