Description

Technical Field

[0001] The utility model relates to the technical field of screen repair, in particular to a portable disassembly knife for repairing a weighing display screen. Background Art

[0002] Weighing display screens are usually used to display the weight of the object being weighed. These display screens can be independent devices or integrated with the weighing system. When performing maintenance, the screen needs to be removed. At this time, a portable disassembly knife is required to assist in the disassembly operation.

[0003] Common portable disassembly knives used for repairing weighing display screens often require manual prying of the blade to separate the screen or clips. However, there is no structure to limit the range of motion, which can easily damage the screen or clips.

[0004] Therefore, with regard to the portable disassembly knife for repairing the weighing display screen, the method of using the blade to pry and separate the screen or the buckle lacks a structure to limit the range of motion, which leads to the problem of easy damage to the screen or the buckle, which urgently needs to be solved to improve the usage scenario. Utility Model Content

[0005] In order to overcome the problem of the common portable disassembly knife used for repairing weighing display screens, the screen is pried apart or the buckle is separated by a blade, but there is a lack of a structure to limit the range of motion.

[0006] The technical solution of the utility model is: a portable disassembly knife for repairing a weighing display screen, comprising a handle, a non-slip finger sleeve installed on the left end of the handle, a fixing plate connected to the upper ends of the handle and the non-slip finger sleeve, a connecting frame is provided on the left end of the fixing plate, a fixed knife group is installed inside the connecting frame, a rotating seat is provided on the top middle part of the fixing plate, a pressing component is movably connected in the middle of the rotating seat, a limiting component is installed on the top of the handle near the right end, and a protective component is connected to the bottom of the fixing plate near the left end.

[0007] Preferably, by setting up a fixed knife group and a pressing component, the cooperation between the knife groups is utilized to separate the screen or the buckle by bidirectionally propping it apart. Compared with the common method of prying with a blade, the risk of damaging the screen or the buckle can be reduced, while improving ease of use. At the same time, by setting up a limit component, the range of working action can be limited to avoid damage to structures such as the screen due to excessive working range, so as to solve the problem that the common portable disassembly knife for repairing weighing display screens uses a blade to pry apart the screen or the buckle, but lacks a structure to limit the range of action, resulting in easy damage to the screen or the buckle.

[0008] Preferably, the fixed knife group includes a bracket, a positioning sleeve, a double-headed blade, and a first screw; the bracket is connected to the bottom of the connecting frame, a positioning sleeve is installed on the top of the bracket near the front and rear ends, and a double-headed blade is installed on the upper end of the bracket in alignment with the positioning sleeve. The positioning sleeve is connected and fixed to the connecting frame by a first screw to facilitate the installation and disassembly of the double-headed blade.

[0009] Preferably, the pressing assembly includes a rotating arm and a mounting block; the rotating arm is hinged in the middle of the rotating seat, and the mounting block is arranged at the left end of the rotating arm.

[0010] Preferably, the pressing assembly includes an auxiliary blade and a second screw; the auxiliary blade is installed in the middle of the mounting block, and the auxiliary blade is connected and fixed to the mounting block by the second screw, so as to facilitate the replacement of the auxiliary blade.

[0011] Preferably, the pressing assembly includes a return spring and a pressing plate; a return spring is connected between the bottom of the rotating arm and the fixed plate, and a pressing plate is arranged at the right end of the rotating arm. When in use, the double-headed blade and the left end of the auxiliary blade are inserted into the gap, the pressing plate is pressed downward, the left end of the rotating arm is rotated upward, and the mounting block drives the auxiliary blade to rise. The display screen is separated from the fixed buckle or glue by the double-headed blade and the auxiliary blade. Compared with the common method of prying with a blade, separation by two-way propping can reduce the risk of damaging the screen or buckle, while improving ease of use.

[0012] Preferably, the limiting assembly includes an internal threaded tube, a screw rod, and a top block; an internal threaded tube is embedded near the right end of the handle, a screw rod is connected to the inside of the internal threaded tube for transmission, a top block is installed on the upper end of the screw rod, and when the top block is rotated, the screw rod and the internal threaded tube cooperate to rise and fall, thereby limiting the expansion range and avoiding damage to the screen and other structures due to excessive working range.

[0013] Preferably, the protection component includes an anti-loss rope and a protective cover; an anti-loss rope is connected to the bottom of the fixed plate near the left end, and a protective cover is hung at the lower end of the anti-loss rope. When not in use, the protective cover is placed on the outside of the double-headed blade and the auxiliary blade to avoid scratching the user when carrying.

[0014] Beneficial effects of the utility model:

[0015] 1. By setting a fixed knife group and a pressing component, the cooperation between the knife groups is used to separate the screen or buckle by bidirectional propping. Compared with the common method of prying with a blade, the risk of damaging the screen or buckle can be reduced, and the usability is improved. At the same time, the setting of the limit component can limit the range of working action to avoid damage to the screen and other structures due to excessive working range, so as to solve the problem that the common portable disassembly knife for weighing display screen repair uses a blade to pry the screen or buckle apart, which lacks a structure to limit the range of action, resulting in easy damage to the screen or buckle;

[0016] 2. When in use, insert the left end of the double-headed blade and the auxiliary blade into the gap, press the pressing piece downward, rotate the left end of the rotating arm upward, and the mounting block drives the auxiliary blade to rise. The double-headed blade and the auxiliary blade are used to separate the display screen from the fixed buckle or glue. Compared with the common method of prying with a blade, the two-way separation can reduce the risk of damaging the screen or buckle, and improve ease of use. Turn the top block, and the screw and the internal threaded tube cooperate to rise and fall, thereby limiting the range of expansion and avoiding damage to the screen and other structures due to excessive working range.
