Description

Structure improved tensimeter

The utility model relates to a kind of tensimeter.

Tensimeter commonly used, as No. 107643 patent case of Taiwan patent announcement " tensimeter is set structure ", it utilizes the stationary shaft in the tensimeter, be with cam by the top, tensimeter central authorities have a circular hole to be inserted in for rotating disc, and the shell tray bottom has seat, seat holds the power lead of going into to have two not conductings, but conducting to a microswitch, microswitch are provided with one protrudes button, utilizes the rotation of turn-button, button is mended be set in a location, by the rotation of pointer, its cam can be pressed the button of microswitch, makes the power turn-on of microswitch, the tensimeter that this patent case is disclosed, the wheel face fluctuating of its cam is difference significantly, and therefore, the sensing of microswitch also can't sensitive move.No. 151376 patent case of Taiwan patent announcement " simple and easy pressure setting device ", system is made of inside and outside enclosure body, be provided with screw thread by all side wall surfaces of the formed room of inner housing and establish the control agent that a top is provided with bull stick with spiral shell, the bull stick of control agent top protrudes out outside the gland bonnet, and be intercalated in the dial plate set on the body housing body in the knob, and be subjected to knob that operation is arranged, and indicator can be set the big or small degree that following square duct enters pressure source in body inner casings body room on the cooperation knob under the indicative of settings of dial plate high scale.Press, this patent case is to utilize to adjust the bull stick rotation that body stretches out, and it is adjusted body and rotates a little, and its pressure changes the difference that promptly has greatly, and therefore, desire is done accurate adjustment and also had inconvenience.

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of manometric structure-improved is provided, and makes it can make things convenient for, adjust accurately set pressure.

The purpose of this utility model is to realize like this, a kind of structure improved tensimeter, include the tensimeter body, it is provided with can be according to the pressure pointer of pressure source action, the outer rim of table is provided with scale, it is characterized in that the body internal ring wall is made of an insulator, the external annulus of this insulator is provided with a ring conducting ring, conducting ring is connected with a power channel circuit, pointer is then led by another power turn-on circuit, body is arranged with a clamshell outward, clamshell can rotate according to body, and this clamshell inwall is provided with one and protrudes electric conductor, and this electric conductor keeps contacting with the conducting ring of body, the top of this electric conductor is provided with one and sets pointer and check plate, and check plate can make contact to power supply with the pressure pointer and lead.The bottom of clamshell is provided with a flange that protrudes in addition, and this flange can be fastened on the bottom of the conducting ring of body, makes clamshell become the location to rotate.

The setting of pressure of the present utility model can be reached easily by the rotation of clamshell, and it is easy to adjust, accurate, thereby realizes the purpose of this utility model.

The accompanying drawing drawing is described as follows:

Fig. 1 three-dimensional exploded view of the present utility model.

Fig. 2 vertical view of the present utility model.

The 3-3 cut-open view of Fig. 3 Fig. 2.

The one circuit of Fig. 4 the utility model connects establishes embodiment.

Below in conjunction with embodiment and accompanying drawing detail explanation the utility model thereof.

See also Fig. 1, the utility model includes members such as body 1, clamshell 2.Body 1 is various tensimeters commonly used, and it has a pressure pointer 11 to move according to pressure source, and its indication was coiled on 12 at quarter.The utility model mainly is to be provided with power turn-on

circuit

13,14 on this tensimeter, the ring wall of this body 1 can be insulator, be provided with a ring conducting ring 15 by its waist, conducting ring 15 is connected by power turn-on circuit 13, the introducing of power supply be can do or 14 connections of another power turn-on circuit and pressure pointer 11 drawn.

Clamshell 2 is in order to be sleeved on body 1 outer the rotation, these clamshell 2 tops can form the top shrouding with transparent glass, dust can not be invaded and pressure pointer 11, the bottom of clamshell 2 is provided with the flange 21 that protrudes circlewise, can be fastened on the bottom of conducting ring 15 by flange 21, make clamshell 2 have the position rotating of difficult drop-off; The inwall of clamshell 2 has an electric conductor 22, electric conductor 22 tops bend inwards and extend into a setting pointer and a

check plate

23,23 of check plates coil on 12 at body 1 quarter, so that can bumping with it when rotating to this present position, pressure pointer 11 connects, conduction 22 is provided with a salient point 24, can keep in touch state with the conducting ring 15 of body 1 by this salient point 24.

As Fig. 2, shown in Figure 3, the situation that combines with clamshell 2 for the utility model body 1, clamshell 2 can rotate with respect to body 1, the check plate 23 that makes this clamshell 2 is referred to coil at quarter the position of 12 required setting, when pressure pointer 11 and check plate 23 crimping, power supply then can be contacted with check plate 23 by pressure pointer 11, forms the conduction path of two power supplys.

As shown in Figure 4, be the circuit diagram of the utility model one embodiment.Pressure pointer 11 in tensimeter contacts with check plate 23, form two power turn-on paths, and when making K switch action closed, can touch the excitatory action of electromagnetic switch (RELAY m), then the normally closed contact m of electromagnetic switch leaves, therefore, motor (M) and air compressor machine (COMPRESSOR) are controlled and stop.
