Description

Technical Field

[0001] The utility model relates to the technical field of weighing sensors, in particular to a convenient installation structure for weighing sensors. Background Art

[0002] A weighing sensor is actually a device that converts mass signals into measurable electrical signal outputs. When using a sensor, the actual working environment of the sensor should be considered first. This is crucial to the correct selection of a weighing sensor. It is related to whether the sensor can work properly, its safety and service life, and even the reliability and safety of the entire scale. Traditional weighing sensors are mostly fixed with multiple bolts, but this installation method is complicated and requires the use of external tools such as wrenches. It takes a lot of time and is not convenient for subsequent disassembly and maintenance.

[0003] For example, a weighing sensor installation structure disclosed in a Chinese patent document (Announcement No.: CN220508216U) inserts a mounting block into a mounting groove and limits the mounting plate through the mounting block, thereby quickly fixing the weighing sensor body to one side of the load-bearing frame, thereby realizing a rapid installation process of the weighing sensor body. By rotating the threaded rod and inserting the threaded rod into the limiting groove, the installation mechanism is limited, making it more stable after installation.

[0004] However, in actual use, since the handles on both sides need to be pulled before disassembly and installation to drive the installation block to work, the operator has to hold the handles with both hands respectively, making it impossible to perform installation and disassembly operations. Therefore, another operator is required to install or remove the weighing sensor, so that two people need to cooperate in the disassembly and assembly process, which makes the disassembly and assembly more cumbersome and reduces practicality.

[0027] Example

[0028] like Figure 1-5 As shown, the utility model provides a technical solution: a convenient installation structure for a weighing sensor, comprising a load-bearing frame 1, the inner bottom wall of the load-bearing frame 1 is fixedly connected with positioning columns 2 distributed in a rectangular array, the outer surfaces of the plurality of positioning columns 2 are movably sleeved with mounting plates 3, the upper ends of the positioning columns 2 are arc-shaped, so as to facilitate the insertion of the mounting plates 3 for preliminary positioning, the lower surface of the mounting plate 3 contacts the inner wall of the load-bearing frame 1, the inner bottom wall of the mounting plate 3 is fixedly installed with a weighing sensor body 4, both side surfaces of the mounting plate 3 are provided with symmetrically distributed limiting slots 5, both side surfaces of the load-bearing frame 1 are fixedly connected with symmetrically distributed mounting blocks 6, and the inner bottom wall of the mounting block 6 is fixedly connected with a first movable sleeve 7;

[0029] The outer surface of the upper end of the first movable sleeve 7 is provided with a convenient disassembly and assembly device, and the convenient disassembly and assembly device includes a second movable sleeve 8, and the inner wall of the second movable sleeve 8 is movably connected to the outer surface of the upper end of the first movable sleeve 7.

[0030] The inner top wall of the second movable sleeve 8 is fixedly connected with a contraction spring 81, one end of the contraction spring 81 is fixedly connected to the inner bottom wall of the first movable sleeve 7, and the upper surface of the second movable sleeve 8 is fixedly connected with a movable rod 82. The elastic force of the contraction spring 81 drives the second movable sleeve 8 to reset and move.

[0031] One end of the movable rod 82 passes through and extends to the upper surface of the mounting block 6. One end of the movable rod 82 is fixedly connected to a pull ring 83. The lower end of the second movable sleeve 8 is provided with symmetrically distributed sliding ball grooves 84. The pull ring 83 facilitates the upward movement of the second movable sleeve 8 by the movable rod 82. After the second movable sleeve 8 rises to a certain height, it is blocked by the top of the mounting block 6.

[0032] A rotating sliding ball 85 is slidably sleeved on the inner wall of the sliding ball groove 84, and a symmetrically distributed guide rod 86 is fixedly connected to the inner wall of one side of the mounting block 6. One end of the two guide rods 86 is fixedly connected to the inner wall of the other side of the mounting block 6, and the outer surfaces of the two guide rods 86 are movably sleeved with a moving plate 87. The rotating sliding ball 85 rolls on the inner wall of the sliding ball groove 84, thereby reducing friction during moving contact.

[0033] A limiting plug 88 is fixedly connected to one side surface of the movable plate 87, one end of the limiting plug 88 passes through and extends to the interior of the load-bearing frame 1, one end of the limiting plug 88 is movably plugged into the inner wall of the limiting slot 5, and a return spring 89 is movably sleeved on the outer surface of the guide rod 86. The inclined surface of the lower end of the limiting plug 88 serves to squeeze the inclined surface of the bottom of the limiting slot 5, thereby improving the stability after installation.

[0034] One end of the two return springs 89 is fixedly connected to the other side surface of the movable plate 87, and the other end of the two return springs 89 is fixedly connected to the other side surface of the mounting block 6. The other side surface of the movable plate 87 is fixedly connected with a pressing block 810. The elastic force of the return spring 89 drives the pressing block 810 to reset and move through the movable plate 87.

[0035] One end of the pressing block 810 passes through and extends to one side surface of the mounting block 6. A movable slide groove 811 and a limiting groove 812 are respectively provided on the upper surface of the pressing block 810. One end of the movable slide groove 811 is connected to the interior of the limiting groove 812. The inner wall of the limiting groove 812 is movably plugged into the outer surface of the second movable sleeve 8. The second movable sleeve 8 plays a role of limiting and fixing the pressing block 810 through the plug-in cooperation with the limiting groove 812.

[0036] Through the convenient disassembly and assembly device, the weighing sensor body 4 can be stably installed and limited by a single press, avoiding the traditional need for two people to cooperate in installation, improving the convenience of installation, and when disassembling, the weighing sensor body 4 can be conveniently disassembled by only pulling the pull ring 83, greatly improving the convenience and practicality of disassembly and assembly.

[0037] The working process of this utility model:

[0038] Step 1: During disassembly, the movable rod 82 is lifted and moved by the pull ring 83. The lifting movement of the movable rod 82 drives the second movable sleeve 8 to lift and move, and stretches its contraction spring 81. When the second movable sleeve 8 is lifted and moves out of the limiting groove 812, the restoring elastic force of the reset spring 89 drives the limiting plug 88 to reset and retract through the movable plate 87, so that the limiting plug 88 moves out of the limiting slot 5. At the same time, the movable slide 811 moves by sliding with the outer surface of the first movable sleeve 7 and pressing the block 810. Finally, the mounting plate 3 is lifted up to separate it from the positioning column 2, and the disassembly of the load cell body 4 is completed.

[0039] Step 2. During installation, insert the weighing sensor body 4 into the positioning column 2 through the mounting block 6 for preliminary positioning, and then push the pressing block 810 for pressing. At this time, the lower end of the second movable sleeve 8 contacts the upper end of the pressing block 810 due to the elastic force of the contraction spring 81, and the rolling of the rotating sliding ball 85 in the sliding ball groove 84 reduces the friction during movement. The movement of the pressing block 810 drives the reset spring 89 to stretch through the movable plate 87, and also drives the limiting plug 88 to move and insert into the limiting slot 5. When the limiting plug 88 is fully inserted into the limiting slot 5, the fixed installation of the weighing sensor body 4 is completed, and the second movable sleeve 8 is located at the upper end of the limiting through groove 812, and the lower end is inserted into the limiting through groove 812 through the elastic force of the contraction spring 81, thereby achieving further limiting fixation.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
