Description

Self-folding tape measure box structure

The utility model relates to a tape measure box structure that can be retracted and unfolded by itself, in particular to a tape measure box structure that can be automatically and manually operated so that the tape measure can be retracted and unfolded by itself.

With the improvement of the quality of modern life, the use of furniture space such as furnishings and purchases in ordinary families is almost inseparable from measuring the size. Therefore, in the past, it was regarded as a tape measure that was only used by professional construction workers, electric welders, etc. The tape box has been popularized in almost every family, especially with the advancement of industrialization and the high labor cost. The existing family affairs must be done by yourself. It is inevitable to measure the size to achieve a neat and beautiful appearance. The tape measure box is suitable Various sizes are the most widely used; however, in the use of tape measure boxes, most of them must be operated by two people, and one person pulls one end for measurement, which makes it inconvenient to use and greatly restricted in use. Therefore, how to design a single-person An operable and more convenient tape measure is a major issue in the field of measuring tools today.

The purpose of this utility model is to solve the above-mentioned "two-person problem" in measurement, and provide a more convenient self-folding tape measure box structure.

The purpose of this utility model is achieved in this way: a tape measure box structure that can be retracted by itself is characterized in that a DC power supply and a motor that can be used for forward and reverse switching are preset in an appropriate place in the tape measure box. The shaft center is set in the shape of a screw rod, and the screw rod is engaged with a gear for transmission. The gear is sleeved on a horizontal shaft. A tension spring is sleeved at the appropriate place on the other end of the horizontal axis, and the other end of the tension spring is fixed on the protruding column in the tape measure box body. There is an S-shaped arc block under the horizontal axis, and several pieces on the tape measure can be engaged with the gears. The holes on the gear and the tape are replaced by the embossing wheel and the embossing line on the tape respectively, and the dial is set on the outer cover of the embossing wheel, and the dial is set in the outer guide groove of the tape measure box; DC The power supply is provided with a connecting guide piece, and a pressing block with a spring is arranged at the guiding piece, and a shrapnel is connected to the upper front end of the pressing piece.

The positive and progressive effect of the utility model is that the tape measure box can be operated automatically or manually, can be retracted and retracted by itself, and can be operated by a single person when measuring objects, which improves the convenience of its measurement.

Below in conjunction with accompanying drawing, the utility model is described in detail:

Fig. 1 is a three-dimensional exploded view of the internal components of the tape measure box of the present invention.

Fig. 2 is a combined sectional view of the tape measure box of the present invention.

Fig. 3 is a cross-sectional view of the action combination of the tape measure box of the present invention.

Fig. 4 is a schematic diagram of a preferred embodiment of another type of tape measure box of the present invention.

Fig. 5 is a schematic diagram of an embodiment of the embossing wheel and the tape measure embossing line in the tape measure box of the present invention.

Fig. 6 is a perspective view of the tape measure case in Fig. 5 .

Fig. 7 is a three-dimensional appearance view of another preferred embodiment of the tape measure case in Fig. 6 .

First of all, it should be explained that the tape measure box 1 can be roughly divided into two types: wide-handle type and pocket type, as shown in Figures 2 and 6 and Figures 4 and 7, as shown in Figures 1-4. A new type of tape measure box structure that can be retracted by itself. A DC power supply 10 and a motor 11 that can be switched between forward and reverse are preset in a suitable place in the tape measure box 1. The power supply 10 can control whether the motor 11 is running or not. ; and its main feature is: the axis of the motor 11 is set in the shape of a screw rod 110, and the screw rod 110 is meshed with a gear 12 for transmission, and the gear 12 is sleeved on a horizontal shaft 13, and the end of the horizontal shaft 13 And set a screw sleeve 14 to fix the gear 12, and set a tension spring 15 at the appropriate place of the other end of the transverse shaft 13, and the other end of the tension spring 15 is fixed on the boss 16 in the tape measure box 1 body, and the tension spring 15 can make horizontal shaft 13 have upward pulling force, be provided with S-type arc block 17 again in tape measure box 1, move up and down with pulling horizontal shaft 13, as manual or automatic control. And the tape measure 18 is provided with several hole positions 181 which can be engaged with the gear 12, and the tape measure 18 can be moved out when the motor 11 rotates; The upper hole position 181 is manual without contact.

In addition, the utility model is a tape measure box structure that can be retracted by itself, wherein the gear 12 cooperates with the hole 181 on the tape measure 18, and can also be replaced by the embossing wheel 19 and the embossing line 182 on the tape measure 18 to cooperate with each other. transmission, and the embossing wheel 19 is covered with a dial 20 as the embossing wheel 19 moves up and down, as manual and automatic control, and the dial 20 can move in the outer guide groove 100 of the tape measure box 1, like a screw sleeve 14 moves in the guide groove 100 the same.

In addition, the utility model is a tape measure box structure that can be retracted by itself, wherein the DC power supply 10 is provided with a guide piece 101 for connection, and the guide piece 101 is provided with a pressure block 103 with a spring 102, which is pressed The block 103 can touch the shrapnel 104, which is in contact with the guide piece 101. The motor 11 can be turned on by pressing the pressing block 103, and the motor 11 can be stopped by the elastic force of the spring 102 when the pressing block 103 is released.
