Description

Technical Field

[0001] The utility model relates to the technical field of weighing equipment, in particular to a waterproof weighing display. Background Art

[0002] The weighing display is equipped with a display screen and buttons, which can operate the electronic scale and display the value of the electronic scale. Since it involves external connection, it is difficult to achieve sealing. When the electronic scale is used to weigh wet goods, moisture can easily enter the inside of the weighing display, causing the internal circuit to be damaged by moisture.

[0003] Publication number "CN217877976U" provides a high-precision electronic scale for water-proof and moisture-proof use for aquatic products. It is known that it includes an electronic scale, which is characterized in that: two groups of gravity sensors are provided on the upper surface of the electronic scale, a cylinder is fixedly connected to the upper end of the gravity sensor, a slot is provided at the upper end of the cylinder, a scale pan is provided above the electronic scale, two groups of plugs matching the slots are fixedly connected to the lower surface of the scale pan, two groups of annular cavities are provided in the electronic scale, the annular cavities match the gravity sensors, a desiccant is placed in the annular cavities, a plurality of through openings connected to the annular cavities are provided on the upper surface of the electronic scale, and a blocking device is provided on the upper surface of the electronic scale. This patented technology can conveniently use the ring to block the through opening and the gravity sensor by setting an annular cavity, a desiccant and a matching ring, and prevent water and humidity in the air from entering the electronic scale on a large scale.

[0004] However, the above device still has the following problems during implementation:

[0005] For example, the patented technology uses a ring to block the opening and the gravity sensor to prevent water and humidity in the air from entering the interior of the electronic scale on a large scale. However, sewage will remain on the top surface for a long time, thereby corroding the ring. Long-term erosion by sewage will shorten the service life of the ring and affect its waterproof performance. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] For example, see Figure 1-4 The utility model provides a waterproof weighing display, including a scale body 1, through holes 2 are respectively opened at the four corners of the top of the scale body 1, and depth grooves 3 are opened at the top of the scale body 1 corresponding to the through holes 2, and cylinders 6 are slidably connected to the inner walls of the through holes 2, and a cleaning mechanism 4 is arranged on the outer wall of the cylinder 6, and the depth of the depth groove 3 is from shallow to deep;

[0026] Further, the cleaning mechanism 4 includes a ring 401, and the inner wall of the ring 401 slides with the outer wall of the cylinder 6, the outer wall of the ring 401 is fixedly connected with a connecting block 402, and the bottom of the connecting block 402 is provided with a sliding groove 404, the top inner wall of the sliding groove 404 is fixedly connected with a spring 403, and the bottom of the spring 403 is fixedly connected with a cleaning block 405, the outer wall of the cleaning block 405 and the inner wall of the sliding groove 404 fit and slide, and the bottom of the cleaning block 405 is squeezed by the spring 403 and set on the inner wall of the depth groove 3;

[0027] Furthermore, a gravity sensor is installed at the bottom of the through hole 2, and the top of the gravity sensor is in contact with the cylinder 6 fixed at the bottom of the scale pan 8, so that the gravity sensor can be used to weigh and display the items on the scale pan 8, and the through hole 2 is blocked by the ring 401 to prevent water from entering. For a more specific waterproof weighing process, please refer to the above-mentioned comparative document, which will not be described in detail here.

[0028] More specifically, in this embodiment, during use, the ring 401 seals the connection between the through hole 2 and the cylinder 6, which can prevent sewage from entering the through hole 2 and corroding the gravity sensor;

[0029] During normal use, when sewage flows into the depth groove 3 along the outer wall of the cylinder 6, the depth of the depth groove 3 is set from shallow to deep, so that the sewage in the depth groove 3 can be guided to flow from shallow to deep along the inner wall. Then, drainage grooves 5 are opened at the corresponding positions of the outer wall of the scale body 1 and a plurality of depth grooves 3, and the inner wall of the drainage groove 5 is connected with the inner wall of the depth groove 3, so that the sewage flowing in the depth groove 3 can be discharged to the outside through the drainage groove 5, preventing the sewage from being retained around the surface of the ring 401, thereby ensuring the service life of the ring 401;

[0030] After long-term use, impurities left by sewage are easily accumulated on the inner wall of the depth groove 3, resulting in poor drainage of the depth groove 3. Therefore, the spring 403 is used to squeeze the cleaning block 405, so that the bottom of the cleaning block 405 can be attached to the bottom of the inner wall of the depth groove 3. At this time, the connecting block 402 is driven to rotate together by the rotating ring 401, so that the cleaning block 405 rotates along the inner wall of the depth groove 3, and the impurities accumulated on the inner wall of the depth groove 3 are pushed and cleaned, and discharged from the drainage groove 5 connected to the deepest part of the inner wall of the depth groove 3, so as to clean the impurities accumulated in the depth groove 3 and make the drainage of the depth groove 3 smooth.

[0031] When the cleaning is completed, the ring 401 is continuously rotated to make the bottom slope of the cleaning block 405 contact the shallowest part of the inner wall of the depth groove 3. The cleaning block 405 can be retracted along the sliding groove 404 by squeezing the spring 403. When the cleaning block 405 is retracted to the shallowest height of the depth groove 3, it will return to the depth groove 3. At the same time, the impurities remaining on the bottom slope of the cleaning block 405 will be cleaned. In addition, due to the squeezing effect of the spring 403, the cleaning block 405 can be fixed at the shallowest height of the inner wall of the depth groove 3, which is convenient for subsequent repeated use.

[0032] Then, the magnet 11 is adsorbed on the surface of the scale body 1 to limit the height of the cross bar 7 embedded on the fixing rod 10, and the sliders 407 fixed on both ends of the cross bar 7 slide on the inner wall of the slot 406, thereby fixing the ring 401.

[0033] Embodiment 2:

[0034] On the basis of the above embodiment, a weighing pan 8 is fixedly installed on the top of the cylinder 6, and a contraction groove 12 is opened in the middle of the four sides of the weighing pan 8, and a fixing mechanism 9 is arranged in the contraction groove 12;

[0035] Further, the fixing mechanism 9 includes a tension spring 901, and one end of the tension spring 901 is fixedly connected to the inner wall of the contraction groove 12, and the other end of the tension spring 901 is fixedly connected to a sliding rod 902, and the outer wall of the sliding rod 902 slides on the inner wall of the contraction groove 12 through the tension spring 901;

[0036] More specifically, in this embodiment, during use, when it is necessary to weigh an object that is larger than the surface of the scale pan 8, the sliding rod 902 can be pulled out. At this time, the rotating rod 904 can be rotated along the inner wall of the groove 903 to an upright state. Because the pulling out of the sliding rod 902 will cause the tension spring 901 to produce an opposite force, the sliding rod 902 can be retracted into the retraction groove 12. During the retraction process, the opposite force of the tension spring 901 is used to clamp the object. The object is clamped by the fixing mechanisms 9 on the four sides to prevent the electronic scale from being placed unstably or accidentally pushed during operation, causing the object to slip.

[0037] Working principle: During normal use, when sewage flows into the depth groove 3 along the outer wall of the cylinder 6, the sewage in the depth groove 3 can be guided to flow from shallow to deep along the inner wall, and the sewage flowing in the depth groove 3 can be discharged to the outside through the drainage groove 5. At the same time, the connecting block 402 can be driven to rotate together by rotating the ring 401, so that the cleaning block 405 can rotate along the inner wall of the depth groove 3, and the impurities accumulated on the inner wall of the depth groove 3 are pushed and cleaned, and discharged from the drainage groove 5 connected to the deepest part of the inner wall of the depth groove 3, so as to clean the impurities accumulated in the depth groove 3 and make the depth groove 3 drain smoothly;

[0038] When the cleaning is completed, the ring 401 is continuously rotated to make the bottom slope of the cleaning block 405 contact the shallowest part of the inner wall of the depth groove 3. The spring 403 can be squeezed to make the cleaning block 405 shrink along the sliding groove 404 to the shallowest height of the depth groove 3 and then return to the depth groove 3. At the same time, the impurities remaining on the bottom slope of the cleaning block 405 can be cleaned. In addition, due to the squeezing effect of the spring 403, the cleaning block 405 can be fixed at the shallowest height of the inner wall of the depth groove 3, which is convenient for subsequent repeated use.

[0039] During use, when it is necessary to weigh an object that is larger than the surface of the scale pan 8, the sliding rod 902 is pulled out, and the rotating rod 904 can be rotated along the inner wall of the groove 903 to an upright state. The opposite force of the tension spring 901 is used to clamp the object. The object is clamped by the fixing mechanisms 9 on the four sides to prevent the electronic scale from being placed unstably or accidentally pushed during operation, causing the object to slip.

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