Abstract
The utility model relates to a dial bench scale with two surfaces, comprising a load bearing mechanism, a zero adjusting mechanism, a transmission mechanism, and pointer displaying mechanisms. The transmission mechanism is composed of a gear long shaft and racks. Racks positioned on the middle part of the gear long shaft are meshed with the racks. Bevel gears arranged on the two ends of the long shaft are separately meshed with bevel gears of the pointer displaying mechanisms on the two sides of the utility model. The two edges of the gear shaft is supported on a bearing seat through a positioning bearing. The utility model has the advantages of simple structure and convenient installation and debugging. Besides, the utility model can ensure the synchronization and accuracy of the display of pointers on two surfaces.
Description
The utility model relates to desk-top equalizer technology field, particularly a kind of two-sided dial-type platform balance.
Existing a kind of two-sided dial-type platform balance, its structure is made up of support mechanism, null setting, endplay device, gear train and indicating mechanism, referring to shown in Figure 1.This support mechanism is realized steadily moving up and down by the structure of parallelogram ABLF, and connecting rod CD and CE that an end is articulated in bearing bar drive rocking bar MO and GN swing, and then cause that both sides rack drives tooth axle, pointer rotate.Said structure is owing to adopt the independent rocking bar of two covers---and gear train is realized two-sided scale demonstration, its pin joint is a lot of in addition, cumulative errors is bigger, every cover is rocking bar independently---and the accumulated error of gear train is not the same, thereby, after the inevitable impact shock, its two-sided pointer demonstration will occur significantly asynchronous, is difficult to satisfy request for utilization in transportation and use.In addition, also there are defectives such as structure is complicated, installation is loaded down with trivial details, debugging difficulty is big in this platform balance.
The purpose of this utility model be to provide in order to overcome above-mentioned weak point a kind of simple in structure, Installation and Debugging convenient, can guarantee the two-sided dial-type platform balance of two-sided pointer display synchronization.
The purpose of this utility model is achieved in that a kind of two-sided dial-type platform balance, comprise the support mechanism of forming by load-bearing frame, main spring, last brace, following brace, pointer indication mechanism and null setting and the load-bearing plate formed by pointer, bevel gear shaft and hairspring, a tooth bar is equipped with in the upright position on the load-bearing frame, bevel gear is equipped with at the wheel and rack meshed gears major axis two ends that are positioned at its middle part, this bevel gear respectively with the engagement of the bevel gear of both sides pointer indication mechanism, gear major axis both sides are bearing on the bearing seat by alignment bearing.Described pointer indication mechanism is packed on the bearing seat.
Advantage of the present utility model is simple in structure, Installation and Debugging are convenient, double inclined plane pointer indication mechanism is by same major axis transmission, do not have design error, thereby it is synchronous and accurate to have guaranteed that two pointers show, moreover, two bevel gears of gear major axis and two bevel gear and pointer indication mechanism are installed on the same bearing seat, this just can guarantee its relative position precision, has further guaranteed two-sided pointer display synchronization and accurate, also installs for parts and has brought convenience.
Fig. 1 is existing a kind of two-sided dial-type platform balance principle of work synoptic diagram.
Fig. 2 is the main TV structure synoptic diagram after the utility model removes load-bearing plate.
Fig. 3 is the partial sectional view of Fig. 2.
By following embodiment the utility model is further elaborated.
Referring to Fig. 2, shown in Figure 3, the two-sided dial-type platform balance of present embodiment is made up of support mechanism, null setting, gear train, pointer indication mechanism and load-bearing plate.Support mechanism by load-bearing frame 1, go up brace 3, brace 14 and two main springs 4 being mounted between the upper and lower brace (3,14) are formed down.Support mechanism is fixed on the iron-clad 17 by parallel-crank mechanism 18, can guarantee the stationarity of support mechanism motion.Last brace 3 is suspended on hanger 21 tops, and following brace 14 is connected with load-bearing frame 1 bottom.Be equiped with null setting between iron-clad 17 tops and hanger 21, it is made up of zeroing nut 2, hanger 21, stage clip 19.One cover pointer indication mechanism respectively is housed on the inclined-plane, platform balance both sides, and it is made up of pointer, index dial, bevel gear 22, hairspring 11 and transparent scale cover 5.Hairspring 11 can guarantee the engagement of two bevel gears (10,22) single face end face.Index dial is fastened on the iron- clad 17, and 5 protections of transparent scale cover are made with ABS plastic in the outside.Bevel gear 22 is bearing on the bearing seat 12.The gear train of this platform balance is made up of tooth bar 6 and gear major axis 8.Tooth bar 6 is vertically fixed on the load-bearing frame 1 interior center by supporting member 16 and stator 15, and makes spur gear 7 normal engaged of tooth bar 6 and gear major axis 8 centres by extension spring 20.Gear major axis 8 both sides on bearing seat 12, and are fixed with high-precision bearing 9 by sleeve supporting on its axle, to reduce the friction force that axial force that bevel gear was produced causes.Bearing seat 12 then is fixed on the base 13.Gear major axis 8 two ends respectively are fixed with a bevel gear 10, respectively with corresponding bevel gear 22 engagements.At last, on load-bearing frame 1, load onto load-bearing plate, make things convenient for customers and weigh when buying extensive stock.
Claims (2)
1, a kind of two-sided dial-type platform balance, comprise the support mechanism of forming by load-bearing frame, main spring, last brace, following brace, pointer indication mechanism and null setting and the load-bearing plate formed by pointer, bevel gear shaft and hairspring, a tooth bar is equipped with in the upright position on the load-bearing frame, bevel gear is equipped with at the wheel and rack meshed gears major axis two ends that it is characterized in that being positioned at its middle part, this bevel gear respectively with the engagement of the bevel gear of both sides pointer indication mechanism, gear major axis both sides are bearing on the bearing seat by alignment bearing.
2, two-sided dial-type platform balance according to claim 1 is characterized in that described pointer indication mechanism is packed on the bearing seat.
