Abstract
The utility model relates to a spring tube pressure gage which comprises joints, a scale disk, a suspension adjustable gear transmisson mechanism (machine core for short), a pull rod, a pointer, a spring tube, etc., wherein, a support which is formed by an upper and a lower parallel planes is arranged between the scale disk and the machine core, the support is in a shape like the Chinese character'shi and is provided with a plurality of connecting holes. The support can be made into a plurality of shapes such as into an H shape, a shape like the Chinese character'shi'or a shape like the Chinese character'tu'according to the actual demand, that is the size of the diameter of the scale disc. The appearance of the bearing surface of the support is generally made into arc shape and can also be made into geometry.
Description
The utility model relates to a kind of tensimeter, particularly a kind of topping up corrosion-proof type bourdon gauges.
General bourdon gauges all is made up of joint, bourdon tube, pointer, gear train, dial, shell etc.And fixing of the gear shaft center of its gear train often need realize by special-purpose orientation tool one centre frame.It is desirable that such tensimeter assembly precision is owed, and body seal is poor, and internal works is subject to external environment and corrodes, and workload is bigger during maintenance.At present commercially available is exactly the bourdon gauges of this form usually.In order to improve sealing property and assembly precision, someone proposes to adopt being connected between watchcase and the joint advanced welding process to replace traditional method that makes it to be connected with securing member, as Jap.P.-openly specially permit J59-188531, U.S. Pat 4896583 etc.Though improved the sealing energy and the reliability that is connected of shell like this, but the structure of part is complicated in addition, requirement on machining accuracy is very high, particularly the center of gear drive is depended on the accuracy of central hole location on the joint base fully, and the center of dial also be cannot say for sure to demonstrate,prove, so manufacturing cost is also higher.
The utility model is exactly on the basis of adopting above-mentioned welding process, and internal mechanism has been done necessary improvement, promptly provides a kind of making easy " ten " font support.This support is used for fixing outstanding the dress adjustable gear drive and the installation dial except suitable, and can guarantee the consistance of both centers.Therefore, this bourdon gauges can not only guarantee the parts firm and reliable connection, and assembling and setting and maintenance are all very convenient.
The utility model is to adopt following frame mode to realize: except can, it comprises joint, dial, outstanding adjustable gear drive, pull bar, pointer, the bourdon tube etc. adorned, and a support that is " ten " font that is made of upper and lower two parallel planes is set at dial with hanging to adorn between the adjustable gear drive.One of punching out is used for determining the center pit of center and has in its and arranged on left and right sides being used for fixing the outstanding hole that adjustable gear passes mechanism of adorning on the lower plane of support, upper and lower on last plane respectively is shaped on the screw that is used for installing dial, the carrying plane profile of support is made generally in circular arc, also can be made into other geometric configuration.In addition, actual needs according to the dial diameter, support can also be made multiple shapes such as " worker ", " scholar ", " soil " word, and the hole on the support and the diameter of screw, quantity and pitch-row also can be adorned the installation dimension of adjustable gear drive and the physical size of dial is decided as required according to outstanding.
Adopt the bourdon gauges of said structure, can guarantee to be installed in the outstanding center of pointer when deflection of adorning on the adjustable gear drive, make outstanding the dress on the last plane that adjustable gear drive can be fixed on instrument connector reliably simultaneously, dial also can be connected on the last plane of support securely, like this when installing and removing arbitrarily, and connect when needing to adjust the initial engagement position of gear, its center can remain unchanged, promptly heavy rational good, like this, not only guaranteed assembly precision but also make maintenance easy accessibility, low cost of manufacture.
Therefore, this support is set in tensimeter, both has been applicable to topping up type bourdon gauges, also be applicable to the tensimeter of other type.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is structural representation-front elevation of the present utility model.
Fig. 2 is structural representation-side view of the present utility model.
With reference to Fig. 1, Fig. 2, to adorn adjustable gear together with pull bar 6 outstanding passes on the plane of band screw that mechanism 5 is placed on joint 1, placement " ten " font support 4 is adorned on the train wheel bridge of adjustable gear drive 5 in outstanding then, will use screw-driving on joint 1 behind the outstanding arc-shaped slot of adorning on the adjustable gear drive 5 of left and right two aperture 7a, 7b aligning on " ten " font support 4 at this moment.Before tightening, the other end with pull bar 6 is fixed on the pipe end of bourdon tube 9 with axial screw earlier, and adjusts the outstanding initial engagement position of adorning adjustable gear drive 5.Fixing outstanding the dress on the basis of adjustable gear drive 5, just can the instrument adjustment finish the back with screw by screw 3a, 3b on " ten " font support 4, dial 2 is fixed on the last plane of " ten " font support 4, at last pointer 8 is pressed into outstanding the dress on the gear shaft of adjustable gear drive 5.Hole 3a, 3b on " ten " font support 4, but the size of 7a, 7b and center pit 7c and the distance pressing force watch case internal diameter between each hole outstanding adorn the actual needs of the installation dimension of adjustable gear drive 5 and the diameter of dial 2 etc. and decide.
Claims (4)
1, a kind of bourdon gauges, comprise joint 1, dial 2, outstandingly adorn adjustable gear drive 5, pull bar 6, pointer 8, bourdon tube 9 etc., it is characterized in that being provided with one between the adjustable gear drive 5 and being " ten " font support 4 with hanging to adorn by what upper and lower two parallel planes constituted at dial 2.
2, by the described bourdon gauges of claim 1, it is characterized in that on the lower plane of described support 4 that one of punching out is used for determining the center pit 7c of center and have in its and arranged on left and right sides being used for fixing outstanding hole 7a, the 7b that adorns adjustable gear drive 5, the upper and lower on last plane respectively is shaped on screw 3a, the 3b that is used for installing dial 2.
3, by claim 1,2 described bourdon gaugess, it is characterized in that the carrying plane profile of described " ten " font support 4 is made generally in circular arc, also can be made into other geometric configuratioies.
4, by claim 1,2 described bourdon gaugess, it is characterized in that described " ten " font support 4 also can make multiple shapes such as " worker ", " scholar ", " soil " word by the actual needs of the diameter of dial 2, middle pore-forming 7c on " ten " font support 4, hole 7a, 7b, the diameter of screw 3a, 3b, quantity and pitch-row also can be adorned the installation dimension of adjustable tooth gear train 5 and the physical size of dial 2 is decided as required according to outstanding.
