Embodiment

Below will explain orally with accompanying drawing and in detail, spirit of the present utility model and embodiment are described, have in any art and usually know that the knowledgeable is after understanding most preferred embodiment of the present utility model, when can by the technology of the utility model institute teaching, be changed and modify, it does not depart from spirit of the present utility model and scope.

Refer to shown in Fig. 1, a kind of tensimeter structure-improved of the utility model, it includes:

One hollow housing 1, is be provided with a bracing frame 12 by group below an arcuate support body 11, and is therebetween combined with a diaphragm 13.

Device 2 is sent on one top, be by bottom a space bar 21 to being provided with an ejector pin 22, and this ejector pin 22 is arranged between a stud 23, and a distance below diaphragm 13 is located at by this space bar 21, makes to form a space therebetween, and this stud 23 is mounted on bottom bracing frame 12.

One display unit 3, is mounted on diaphragm 13.

Be provided with a bag 4 between this diaphragm 13 and space bar 21, and be equiped with the liquid 5 of certain density in this bag 4, and this ejector pin 22 one end is provided with a flange 221, can to being located in stud 23.

This liquid 5 above-mentioned for hydraulic oil be preferred forms.

Above-mentionedly between this flange 221 and stud 23, be provided with an O-ring seal 231.

Solid bodies 6 ﹝ with certain density can be established separately to refer to figure 3 Shi ﹞ between this diaphragm 13 above-mentioned and space bar 21.

Refer to shown in Fig. 2, during enforcement, to be arranged on stud 23 for measuring pressure source, pressure source entered in stud 23 and pushes ejector pin 22, to promote space bar 21 by ejector pin 22, then making the force value of liquid 5 transmitting and converting in bag 4 and bag thereof push diaphragm 13, made display unit can demarcate surveyed pressure, and above-mentioned operating principle is according to F=P × A formula, belongs to existing current techique, no longer set forth at this; When entering in stud 23 when pressure source quick high-pressure; ejector pin 22 can be driven upwards jacking fast; and the flange 221 of this ejector pin 22 just can to being located in stud 23; can prevent ejector pin 22 from cruelly rushing (being commonly called as quick-fried table); cause tensimeter to damage situation to occur; and the liquid 5 be located between diaphragm 13 and space bar 21, can avoid leaking the error caused by bag 4 protection and produce.

Liquid 5 density in this bag 4 according to the pressure source that need measure, can be made a suitable density and changes, and uses to meet various product.

Refer to shown in Fig. 4, it is another device for carrying out said, by liquid 5 in the bag 4 between diaphragm 13 and space bar 21 and bag thereof, be replaced by the solid bodies 6 (as: rubber) with certain density, except the operation can installed according to same liquid state, then without the leakage shortcoming of liquid installing, and there is the surcharge of convenient installing.

In sum, tensimeter structure-improved of the present utility model, bag is mainly utilized to be protected by low pressure liquid, except Leakage prevention, also the object being convenient to install is had, the flange of ejector pin then can prevent quick-fried table from producing, and use reduces failure rate greatly, has the lifting of certain degree in practicality aspect; Therefore the utility model is technically structure improved at tensimeter, really there is concrete and breakthrough improvement.

The above is only preferred implementation of the present utility model, it is to be noted, these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model, and, after having read content of the present utility model, relevant technical staff in the field can make various change or amendment to the utility model, and these equivalent form of values fall into the application's appended claims limited range equally.
