Abstract
The utility model relates to a vehicle weighing-appliance sensor dustproof cover which is a seal cover sheathed at the lower part of the vehicle weighing-appliance sensor and outside the lower bearing component on the baseplate. The configuration is a flexible elastic cover in the shape of a barrel. The upper end is supported by a digital sensor seal weld opening, and the lower end is supported by a baseplat. So the lower segment of the sensor and the sensor connecting component are covered to form a closed space. The utility model thoroughly solves the hidden trouble that when working, the dust wedges into the dustproof ring and the sensor to cause the abnormal damage of the sensor, protects the sensor to prolong the service life, and ensures the measuring accuracy and the stability of the vehicle weighing-appliance. The application of the sensor dustproof cover reduces the maintaining frequency of the sensor and increases the stability of the vehicle weighing-appliance. The application of the sensor dustproof cover is according to the JJG539-97 regulations to check, so the mobility, accuracy and the discrimination of the free scale are qualified. The declination of the eccentric load testing and the measuring range testing are both smaller than the declination required by the checking regulation.
Description
Technical field:
The utility model belongs to the electronic vehicle weighing apparatus parts, particularly electronic vehicle weighing apparatus digital transducer dirt-proof boot.
Background technology:
Present original digital transducer adopts dust ring to carry out proofing dust and protecting; the operation of weighing than rugged environment in; because shaking of sensor makes between dust wedging dust ring and the sensor; need artificial regular maintenance; as maintain the untimely dust ring that will cause and lost efficacy; thereby cause the improper damage of sensor, influence the measuring accuracy and the stability of truck scale.
Summary of the invention:
Technical problem to be solved in the utility model is: a kind of truck scale pickup dust-proofing cover is provided, and thorough solution is because of environmental factor and can not in time maintain the improper damage of the sensor that causes.Improved the stability of truck scale measuring process.
The technical solution of the utility model is:
A kind of truck scale pickup dust-proofing cover is characterized in that: it is the outer sealing shroud of following pressure part that is enclosed within on truck scale sensor bottom and the foundation plate, and its profile is the flexible resilient cover of tubbiness.
A kind of pickup dust-proofing cover is enclosed within the hypomere of digital transducer.The upper end is supported by digital transducer seal weld interface, and the lower end is supported by foundation plate, covers sensor hypomere and sensor web member assembly, forms confined space.
The pickup dust-proofing cover is elastomeric material, can disassembled and assembled freely.Because the characteristic of elastomeric material, in the truck scale weighing process, with sensor shake the generation elastic deformation, prevent that foreign material from invading confined space.
The utility model effect is:
Between dust wedging dust ring and the sensor, cause the hidden danger of the improper damage of sensor when thoroughly solving the truck scale operation, protection extension sensor its serviceable life, guarantee the measuring accuracy and the stability of truck scale.The pickup dust-proofing cover is used, and has reduced sensor daily servicing number of times, the truck scale stable performance.The pickup dust-proofing cover is used, and examines and determine by the JJG539-97 rules, and empty scale mobility, accuracy, resolving ability etc. are qualified, the deviation that unbalance loading test and range test all require less than vertification regulation.

Embodiment:
A kind of pickup dust-proofing overlaps 1, is enclosed within the hypomere of digital transducer 2.Press the sensor mounting means, place truck scale digital transducer installation site.The upper end is supported by digital transducer seal weld interface 3, and the lower end is supported by foundation plate 4, covers sensor hypomere and sensor web member assembly: following pressure part 5, dust-proof cushion 6 forms confined space.
The pickup dust-proofing cover is elastomeric material, can disassembled and assembled freely.Because the characteristic of elastomeric material is in the truck scale weighing process, with sensor shake the generation elastic deformation, prevent that foreign material from invading confined space.
