Description

Technical Field

[0001] The utility model relates to the technical field of electronic scales, in particular to an electronic scale with a detachable tray. Background Art

[0002] An electronic scale is a weighing instrument that uses the principle of force and deformation of electronic strain elements to output tiny analog electrical signals, which are transmitted to a weighing display instrument through a signal cable to perform weighing operations and display weighing results. In daily life, the items to be weighed are placed in the tray of the electronic scale. The weight obtained after the numbers displayed on the electronic scale stop jumping is the weight of the item. During use, stains on the items being weighed will be stained on the tray, and the tray needs to be disassembled and cleaned frequently. Most existing electronic scales are not convenient for disassembling the tray, which affects the hygiene and safety of the electronic scale during use.

[0003] For example, a Chinese patent document discloses an electronic scale with a detachable tray (Announcement No.: CN219977559U). Although this patent uses a bracket, a block and a cylinder, when the tray needs to be removed for cleaning, the pressure plate is pressed so that one end of the pressure rod in the empty groove drives the rotating shaft to slide in the slide groove, so that the cylinder slides to the top in the cylinder and lifts up the bracket, and the L-shaped rod rotates to the bottom. Since one end of the block is arc-shaped, it will drive the block to rotate to the bottom and detach from the tray, thereby facilitating the removal of the tray for cleaning and avoiding health and safety hazards.

[0004] However, due to the fixed size of the L-shaped rod, only pallets of a single size can be limited and fixed, which limits its use and has low practicality. When the object to be weighed is large and cannot fit inside the pallet, it is usually mounted above the pallet for weighing. However, due to the obstruction of the card block, there are two protrusions above the pallet, which may cause the object to tilt and slide when it is mounted for weighing. Utility Model Content

[0027] A torsion spring 71 is fixedly connected to the front of the special-shaped block 7, which plays a role in driving the special-shaped block 7 to reset and rotate. One end of the torsion spring 71 is fixedly connected to the front inner wall of the installation cavity 4. A mounting groove 72 is provided on the upper surface of the installation block 3. The inner walls on both sides of the installation groove 72 are provided with symmetrically distributed first guide holes 73. Positioning blocks 74 are movably inserted into the inner walls of the installation groove 72. The two side surfaces of the positioning block 74 are provided with symmetrically distributed positioning grooves 75. One end of the positioning groove 75 is connected to one end of the first guide hole 73. A tray body 76 is fixedly connected to the upper surface of the positioning block 74. The tray body 76 can be provided with a plurality of different sizes to meet different usage requirements, and the tray bodies 76 of various sizes can be conveniently disassembled and assembled through the cooperation of the positioning blocks 74. The inner walls on both sides of the installation cavity 4 are provided with symmetrically distributed second guide holes 77.

[0028] The inner wall of the second guide hole 77 is movably sleeved with a movable rod 78, and the outer surface of the movable rod 78 is movably sleeved with a guide block 79, which serves to guide and limit the movement of the movable rod 78. One side surface of the guide block 79 is fixedly connected to the inner wall of one side of the installation cavity 4, and one end of the movable rod 78 is fixedly connected with a sliding ball 710, and the outer surface of the sliding ball 710 contacts the one side surface of the special-shaped block 7, and the sliding ball 710 is in sliding contact with the special-shaped block 7, thereby reducing the friction generated, facilitating the extrusion and movement of the movable rod 78, and the movable rod 78 is movable.

One end of the contraction spring 712 is fixedly connected to one side surface of the mounting block 3, and a positioning rod 713 is fixedly connected to one side surface of the connecting block 711. The restoring elastic force of the contraction spring 712 drives the positioning rod 713 to reset and move through the connecting block 711. The outer surface of the positioning rod 713 is movably connected to the inner wall of the first guide hole 73, and one end of the positioning rod 713 is movably connected to the inner wall of the positioning groove 75.

[0029] By providing a rotating disassembly device, the tray bodies 76 of different sizes can be conveniently disassembled and installed, thereby improving practicality. When in use, the top of the tray body 76 is not blocked, thereby facilitating stable installation and weighing when weighing larger objects.

[0030] Working principle: Step 1, when disassembling the tray body 76, the driving handle 6 is used to drive the driving rod 5 to rotate 90 degrees, and the rotation of the driving rod 5 drives the special-shaped block 7 to rotate, and the rotation of the special-shaped block 7 drives the torsion spring 71 to rotate to generate a reset torque, and when rotating, the sliding ball 710 is used to squeeze one end of the movable rod 78, so that the movable rod 78 moves through the cooperation of the guide block 79, thereby driving the connecting block 711 to move, and the movement of the connecting block 711 drives the contraction spring 712 to stretch, and drives the positioning rod 713 to move, so that one end of the positioning rod 713 moves out of the positioning groove 75, and then the tray can be lifted up, so that the positioning block 74 is separated from the installation groove 72, and the disassembly is completed;

[0031] Step 2, when installing the tray body 76, first drive the driving rod 5 to rotate ninety degrees through the driving handle 6, then insert the tray body 76 into the positioning groove 75 through the positioning block 74 for preliminary limiting, and release the driving handle 6. At this time, the torsion force of the torsion spring 71 drives the special-shaped block 7 to reset and rotate through the driving rod 5. When the squeezing force of the special-shaped block 7 on the movable rod 78 disappears, the reset elastic force of the contraction spring 712 drives the movable rod 78 to reset and move. The reset movement of the movable rod 78 drives the positioning rod 713 to reset and move through the cooperation of the connecting block 711, so that one end of the positioning rod 713 is inserted into the positioning groove 75, and the positioning block 74 is further limited and fixed, thereby completing the installation of the tray body 76.
