Abstract

The utility model relates to a retractable band tape box structure. A DC power and a motor with positive rotation and reverse rotation switch are prearranged in the proper position in a band tape box. The shaft center of the motor is set up into a spiral rod shape, and the spiral rod is in mutual engagement transmission with a gear. The gear is sheathed on a cross shaft of which end is provided with a thread sleeve, and is arranged in a guide groove out of the band tape box. The proper position of the other end of the cross shaft is sheathed with an extension spring of which the other end is fixed on a convex column in the band tape box. The lower part of the cross shaft is provided with an S-shaped arc block; the band tape is provided with a plurality of hole sites which can be engaged with the gear mutually. The band tape box can be automatically operated or manually operated. The utility model can be operated by one man when measuring the object. The measuring convenience of the utility model is enhanced.

Description

Auto-retractable flexible rule box structure

The utility model relates to a kind of auto-retractable flexible rule box structure, particularly a kind ofly can reach manual operation automatically, makes the tape measure flexible rule box structure of folding and unfolding voluntarily.

Raising along with modern life quality, general family is in the utilization in furniture spaces such as ornaments, purchase, almost be unable to do without and measure size, therefore be regarded as having only professional building worker, electric welder in the past ... or the like, the flexible rule box of Shi Yonging, now be popularized for almost each family, especially industrialization progress, cost of labor is surging, affairs must do it yourself to finish in the existing family, unavoidable measure size be definitely need, in the hope of neat appearance, and be employed the most extensive with the suitable various sizes size of flexible rule box; But, on flexible rule box uses, mostly must operate with two people, one people draws an end to measure, and causes to use and goes up inconvenience, is restricted widely in the use, therefore how to design single the operation and tape measure more easily, be key subjects of survey instrument circle now.

The purpose of this utility model is to solve " double problem " in the above-mentioned measurement, and a kind of auto-retractable more easily flexible rule box structure is provided.

The purpose of this utility model is achieved in that a kind of auto-retractable flexible rule box structure, its characteristics are: the default direct current power supply and of appropriate location just can done in flexible rule box, the motor that counter-rotating is switched, it is shaft-like that this axle center of motor is set as spiral, this screw rod then with the mutual interlock transmission of a gear, this gear is nested with on a transverse axis, this transverse axis end is provided with a swivel nut, and place in the outer guide groove of flexible rule box, the sheathed extension spring of the appropriate location of this transverse axis other end, this extension spring other end is fixed on the tape measure box body convex post, this transverse axis below is provided with S type arc piece, establish on the tape measure several can with the gear position, hole of interlock mutually; Position, hole on this gear and the tape measure substitutes with the embossed lines on embossed wheel and the tape measure respectively, and at this embossed wheel overcoat to dial plate, this group plate is located in the outer guide groove of flexible rule box; The direct supply place is provided with the connection guide card, and is provided with the briquetting of tool one spring at the guide card place, and the top front end of briquetting is connected with a shell fragment.

But positive progressive effect of the present utility model is the operation of this flexible rule box automatic or manual, folding and unfolding voluntarily, but one man operation when measuring article has improved the convenience of its measurement.

Below in conjunction with accompanying drawing the utility model is elaborated:

Fig. 1 is a flexible rule box inner member three-dimensional exploded view of the present utility model.

Fig. 2 is a flexible rule box assembled sectional view of the present utility model.

Fig. 3 is a flexible rule box combination of actions cut-open view of the present utility model.

Fig. 4 is the flexible rule box preferred embodiment synoptic diagram of another pattern of the utility model.

Fig. 5 is the interior embossed wheel of flexible rule box of the present utility model and the embodiment synoptic diagram of tape measure embossed lines.

Fig. 6 is the stereo appearance figure of the flexible rule box of Fig. 5.

Fig. 7 is the stereo appearance figure of another preferred embodiment of flexible rule box of Fig. 6.

At first be noted that, flexible rule box 1 just in appearance summary can be divided into wide type and pocket two kinds of patterns, as Fig. 2,6 and Fig. 4,7 shown in, as Fig. 1-shown in Figure 4, a kind of auto-retractable flexible rule box structure of the utility model, the default direct current power supply 10 and of appropriate location can be made the motor 11 that forward and backward is switched in flexible rule box 1, whether is turned round by this this motor 11 of power supply 10 may command; And its principal feature is: these motor 11 axle center are set as screw rod 110 shapes, screw rod 110 then with a gear 12 mutual interlock transmissions, and gear 12 is nested with on a transverse axis 13, and transverse axis 13 ends and establish a swivel nut 14 with fixed gear 12, again at the transverse axis 13 sheathed extension spring 15 of appropriate location of end in addition, extension spring 15 end in addition then is fixed on the interior projection 16 of flexible rule box 1 body, can make transverse axis 13 have the power that upwards lifts by extension spring 15, in flexible rule box 1, be provided with S type arc piece 17 again, do upper and lower moving to pull transverse axis 13, to control as manual or automatic.And establish on the tape measure 18 several positions, hole 181 can with gear 12 interlock mutually, can when motor 11 rotates, tape measure 18 be moved out outward; And S type arc piece 17 is stirred transverse axis 13 upwards the time, and then the position, hole on gear 12 and the tape measure 18 181 is contactless and be manual mode.

In addition, a kind of auto-retractable flexible rule box structure of the utility model, wherein this gear 12 cooperates with position, hole 181 on the tape measure 18, can also embossed wheel 19 and tape measure 18 on embossed lines 182 substitute, mutually transmission is done in interlock, and these embossed wheel 19 overcoats do embossed wheel 19 upper and lower moving to dial plate 20, with as manually and automatically controlling, and this group plate 20 can move in the guide groove 100 outside flexible rule box 1, moves in guide groove 100 as swivel nut 14.

Also have, a kind of auto-retractable flexible rule box structure of the utility model, wherein these direct supply 10 places are provided with guide card 101 and connect, and be provided with the briquetting 103 of tool one spring 102 at guide card 101 places, can touch shell fragment 104 by briquetting 103, touch logically mutually, push down briquetting 103 and can rotate by conducting motor 11 with guide card 101, decontrol briquetting 103 then by the elastic force of spring 102, can stop motor 11 and rotate.
