Description
Technical field
The utility model relates to the instrument and meter structure, and more particularly, it relates to a kind of protective device of balance.
Background technology
At the non-working condition of balance, especially in the transportation, for guaranteeing that sensor damages because of overload, need provide protection, thereby prolong the serviceable life of sensor and balance.
Summary of the invention
The purpose of this utility model is, a kind of protection mechanism of balance is provided, and prevents that balance sensor when non-working condition from damaging because of overload.
The purpose of this utility model is achieved through the following technical solutions, and the balance protection mechanism according to the utility model proposes comprises support member, scale susceptor body and scale pan carriage; Support member is rotatable, and its lower end is supported on the scale susceptor body, and the upper end is provided with draw-in groove, and draw-in groove can fasten with scale pan carriage or break away from during the support member rotation.During engaging, scale pan carriage can not free length travel; Support member is at least one position of rotation, and draw-in groove can break away from hole clipping, makes the vertical free displacement of scale pan carriage.The scale susceptor body is arranged on the scale body, and scale pan carriage is used to support the scale pan, and links to each other with sensor.
The support member lower end is provided with groove, correspondingly is provided with card-bit part on the scale susceptor body, engages with groove.Like this, the support member lower end is supported on the pedestal, and can prevents that support member from coming off when released state.
On support member, also projection can be set, and be supported on the pedestal.Like this, can make supports support more firmly on pedestal, prevent that support member from producing axial displacement greatly because of scale pan carriage load when lock-out state.
Draw-in groove is located at both sides, support member upper end, on the scale pan carriage hole clipping is set, and draw-in groove fastens with hole clipping or breaks away from during the support member rotation, thereby supported of scale pan carriage is engaged or breaks away from support member.Hole clipping shape and support member upper end shape and draw-in groove shape match, and the support member upper end can be passed from draw-in groove, and draw-in groove can rotate in hole clipping, and support member rotates to an angle, and draw-in groove can engage with hole clipping, thereby make the scale pan carriage can not axial displacement.
Better, support member upper end two side bayonet slot height differences correspondingly are provided with differing heights hole clipping wall at the hole clipping periphery, cooperate with draw-in groove respectively, are convenient to control the anglec of rotation of support member.
In the support member bottom cue mark can be set, be convenient to judge support member position of rotation of living in when rotated, simultaneously, the support member location pointer can correspondingly be set on the scale body, be in locking (being that scale pan carriage engages with support member) and released state (being that scale pan carriage and support member break away from) to determine balance easily.
By structural arrangements mode of the present utility model,, can prevent effectively that balance from damaging because of overload at the non-working condition lower sensor owing to be provided with protection mechanism in the balance.The utility model compact conformation, easy to use, low cost of manufacture is with a wide range of applications.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Accompanying drawing is depicted as a kind of preferred embodiment of the present utility model.This balance protection mechanism comprises support member 1, scale susceptor body 2 and scale pan carriage 3, and wherein scale susceptor body 2 is arranged on the scale body 4, and 3 on scale pan carriage supports the scale pan, and links to each other with sensor.
As shown in Figure 1 and Figure 2, support member 1 is rotatable, and its upper end 10 integral body are flat prismatic, both sides establish square draw-in groove 12 and 12 ', the bottom land 121 and 121 of two side bayonet slots ' concordant, draw-in groove 12 is than draw-in groove 12 ' high slightly.
As shown in Figure 3, scale pan carriage 3 has and draw-in groove 12,12 ' the hole clipping 31 that fastens, shape can be passed for the upper end 10 of support member as shown in Figure 4, and do not touch during support member 1 rotation with hole clipping 31, in addition, hole clipping wall 311 and 311 ' the bottom concordant, hole clipping wall 311 is than hole clipping wall 311 ' high slightly, so that draw-in groove 12 engages with hole clipping wall 311, draw-in groove 12 ' then and hole clipping wall 311 ' engage.This is provided with the rotation screens that helps support member 1, and distinguishes its state of living in.
Support member lower end 11 has groove 14, and above groove 14, a side of support member also fixedly installs projection 13; Pedestal 2 has the cavity 23 that holds support member 1, its sidewall 21 is provided with elasticity card-bit part 210, when support member 1 places cavity 23, its groove 14 fastens with pedestal card-bit part 21, simultaneously, projection 13 on the support member just in time is supported in the top 211 of pedestal sidewall 21, and pedestal 2 overhead view synoptic diagram as shown in Figure 5.Support member 1 bottom is circular, and arrow cue mark 15 is set, and scale body bottom then has the designator 41 of support member state of living in.
This protection mechanism installation and indicating mode are shown in Fig. 6-9.
Shown in Figure 6, support member 1 is passed from base cavity 23, groove 14 on support member fastens with pedestal card-bit part 21, at this moment, the support member top is passed from scale pan carriage hole clipping 31, and the bottom land 121,121 of draw-in groove 12 ' higher slightly than hole clipping wall 311, the 311 ' bottom of scale pan carriage, so as during support member 1 rotation and the hole clipping wall do not touch.
Figure 7 shows that, 1 dextrorotation of support member among Fig. 6 is turn 90 degrees, and this moment, the draw-in groove 12 of support member upper end was sticked on the scale pan carriage hole clipping wall 311, draw-in groove 12 ' then and hole clipping wall 311 ' engage, simultaneously, 13 of the projections of support member lower end are supported on the pedestal sidewall top 211.Like this, 1 pair of scale pan carriage of support member 1 has carried out axial restraint, and carriage 1 can not axially carry out free displacement, thereby makes the load of the scale pan not be delivered to sensor by scale pan carriage 3, perhaps reduces the pressure that transmitted, plays the effect of protection sensor.
Figure 8 shows that, with the support member among Fig. 71 again clockwise direction rotated for 90 ends, at this moment, support member upper end draw-in groove 12,12 ' respectively and scale pan carriage hole clipping wall 311,311 ' disengaging, and support member lower end projection 13 still is supported on the pedestal sidewall top 211, and like this, scale pan carriage 3 can be done axial free displacement by hole clipping 31, load on the scale pan can be sent to sensor 5 by carriage 3, realizes the normal weighing of balance.
When needs remove this support member 1 from scale body 4, get final product by above-mentioned opposite procedure operation.In addition, be clear expression support member 1 present position, support member 1 bottom is provided with indication piece 15, simultaneously, is provided with the locking and unlocking mark 41 in scale body 4 bottoms, as shown in Figure 9.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all belongs within the scope of technical solutions of the utility model any simple modification, equivalent variations or modification that above embodiment did.
