Description
Technical field
The utility model relates to LOAD CELLS field, especially relates to the LOAD CELLS of a kind of weldless steel tube sealing.
Background technology
Parallel girder LOAD CELLS is one of sensor the most frequently used in LOAD CELLS, is widely used in the industry fields such as electronic scales, kitchen scale, jewelry scale, is indispensable core component in industry and agricultural automation system.The advantage of parallel girder LOAD CELLS is that precision is high, measurement range is wide, the life-span is long, structure is simple, good frequency response, can work under severe conditions, be easy to realize miniaturization, integration and diversification of varieties etc.
Conventional sensor adopts sylphon seal technology, the sensor of traditional bellows-type, in order to sensor accuracy after installing corrugated tube is unaffected, corrugated tube wall thickness only has 0.15mm usually, corrugated pipe wall is thin, and often easily damage, the breakage of corrugated tube directly can cause the damage of whole sensor; In addition, corrugated pipe wall is thin, sensor also can be made to be not suitable for high pressure water cleaning, and be very easy to dirt deposits in the groove of corrugated tube, should not clean, be not suitable for the application of some food weighing-appliances.
Utility model content
The purpose of this utility model is the defect overcoming prior art, provides the LOAD CELLS that a kind of weldless steel tube seals, and adopts stainless-steel tube to replace sylphon seal elastic body, to make whole sensor in the circular appearance without seamed edge corner angle, is easy to cleaning; And stainless-steel tube wall thickness, not fragile.
For achieving the above object, the utility model proposes following technical scheme: a kind of LOAD CELLS of weldless steel tube sealing, comprise sealed steel pipe shell, the elastic body be sealed in described steel tube shell, be mounted on foil gauge in described elastic body and pcb board, the described elastomeric left and right sides is symmetrically arranged with a stress diaphragm, described sealed steel pipe is welded and fixed on described stress diaphragm, and described pcb board is electrically connected with described foil gauge
Preferably, described sensor also comprises cable interface.
Preferably, described sealed steel pipe shell is seamless stainless steel pipe shell, and described sealed steel pipe shell is hollow cylindric.
Preferably, described sealed steel pipe shell adopts laser bonding mode to be welded and fixed on described stress diaphragm.
Preferably, the wall thickness of described sealed steel pipe shell is 2mm.
The beneficial effects of the utility model are: 1, the utility model is by the circular structure of whole sensor configuration design, and whole sensor is without seamed edge, corner angle, and such sensor is not easy to damage, and without corner angle design, sensor is very easily cleaned; 2, the utility model devises dual stressed films slice structure to Sensor Elastic Element, is welded on two diaphragms by a weldless steel tube shell, has both reached high strength and the seal request of sensor, reaches again the food hygiene requirement without dead angle seamed edge.

Embodiment
Below in conjunction with accompanying drawing of the present utility model, clear, complete description is carried out to the technical scheme of the utility model embodiment.
Shown in composition graphs 1, Fig. 2, the LOAD CELLS of a kind of weldless steel tube sealing that the utility model discloses, comprises sealed steel pipe shell 10, elastic body 20, foil gauge 30, pcb board 40 and cable interface 50.Sealed steel pipe shell 10 is for sealing elastomer 20, and during enforcement, sealed steel pipe shell 10 can adopt seamless stainless steel pipe shell, and profile is hollow cylindric.Like this, whole sensor profile is without seamed edge, corner angle, and such sensor is not easy to damage, and without corner angle design, sensor is very easily cleaned.And compared with only having 0.15mm with the ripple wall thickness of traditional sensors, the utility model have employed the thick solid drawn tube stainless steel casing of 2mm, reaches durable, non-damageable object.
Elastic body 20 is encapsulated in sealed steel pipe shell 10, and elastic body 20 is the core parts of sensor, can produce elastic deformation under external force.
Have hole slot 21 in the middle part of elastic body 20, foil gauge 30 is pasted in the hole slot 21 of elastic body 20, for together producing distortion with elastic body 20 under external force.Preferably, the left and right sides of elastic body 20 is symmetrically arranged with a stress diaphragm 22, and sealed steel pipe 19 adopts laser bonding mode to be welded and fixed on stress diaphragm 22, so both reaches high strength and seal request, reaches again the food hygiene requirement without dead angle seamed edge.
Pcb board 40 is electrically connected with foil gauge 30, and is encapsulated by PCB cover plate 41, for the resistance of foil gauge 30 is converted to electric signal, is transferred out by cable interface 50.
Technology contents of the present utility model and technical characteristic have disclosed as above; but those of ordinary skill in the art still may do all replacement and the modification that do not deviate from the utility model spirit based on teaching of the present utility model and announcement; therefore; the utility model protection domain should be not limited to the content that embodiment discloses; and various do not deviate from replacement of the present utility model and modification should be comprised, and contained by present patent application claim.
