[0002] The tape measure is a common measuring tool in daily life. The one that everyone often sees is the steel tape measure, which is commonly used in construction and decoration, and is also one of the essential tools for the family. It is divided into fiber tape measures, tape measures, waist circumference rulers, etc. Lu Ban ruler and Wen Gong ruler are also steel tape measures. The tape measure can be rolled up because there is a spring inside the tape measure. When it is pulled out to measure the length, the length of the ruler and the spring is actually lengthened. The brake assembly is pressed to prevent the tape from retracting. Once the measurement is completed and the brake assembly is released, the spring inside the tape measure will automatically shrink, and the tape will also shrink under the action of the spring force, so the tape measure will roll up. In order to adapt to construction conditions with limited light at night, a fluorescent tape measure has been produced on the market. By using fluorescent materials to print scale lines on the tape, it is easier to read the tape measure.

[0003] However, when the existing fluorescent tape measure is used in a dark environment, a light source needs to be used to illuminate the tape to make it fluoresce. The applicability of the fluorescent tape measure is not strong. This solution solves this technical problem. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0022] See also Figure 1-Figure 4 A night-time tape measure comprises a housing 1, a rotating shaft 2 rotatably disposed in the housing 1, a tape 3 wound on the rotating shaft 2, and a brake assembly detachably abutting against the tape 3, wherein the brake assembly is slidably disposed on the side of the housing 1, and the scale lines on the tape 3 are printed with fluorescent material;

[0023] A lamp bead 4 is arranged on the shell 1 above the tape 3, a battery 5 connected to the lamp bead 4 is arranged in the shell 1, a solar panel 6 connected to the battery 5 is arranged on the outer side of the shell 1, and a lamp bead switch 7 is arranged between the lamp bead 4 and the battery 5.

[0024] One end of the lamp bead 4 is connected to one end of the battery 5 by a wire 41, the other end of the lamp bead 4 is provided with a conductive sheet 1 42, and the other end of the battery 5 is provided with a conductive sheet 2 43. The conductive sheet 1 42 and the conductive sheet 2 43 are arranged close to each other and have an overlapping length along the sliding direction of the brake block 81. The lamp bead switch 7 is provided with a conductive block 71 which can be detachably contacted with the conductive sheet 1 42 and the conductive sheet 2 43 respectively, and the lamp bead switch 7 is arranged on the brake assembly.

[0025] The brake assembly includes a brake block 81 with one end detachably abutting against the ruler tape 3, and a brake button 82 connected to the other end of the brake block 81. The housing 1 is provided with a through hole 11, and the brake block 81 and the brake button 82 are respectively slidably arranged on both sides of the through hole 11;

[0026] The lamp bead switch 7 includes a connecting column 72 that slides through the brake button 82, a button 73 connected to one end of the connecting column 72, a conductive block 71 connected to the other end of the connecting column 72, and a spring 74 is sleeved on the outer side of the connecting column 72. One end of the spring 74 abuts against the button 73, and the other end of the spring 74 abuts against the brake button 82.

[0027] An abutment block 9 is disposed in the housing 1 at a position corresponding to the brake block 81 . The abutment block 9 and the brake block 81 are disposed on two sides of the ruler tape 3 , respectively.

[0028] A groove 10 is provided on the surface of the brake button 82 .

[0029] The specific working process of this utility model:

[0030] When using the night measuring tape in a dark environment, one hand presses the button 73 of the lamp bead switch 7, the button 73 overcomes the elastic force of the spring 74 and drives the conductive block 71 to move through the connecting column 72. Under the support of the brake block 81, the conductive block 71 contacts the conductive sheet 1 42 and the conductive sheet 2 43 at the same time, so that a path is formed between the battery 5 and the lamp bead 4, and the lamp bead 4 lights up. The other hand gradually draws out the tape 3, and at the same time, the hook of the tape 3 is hung at the starting point of the object to be measured with the help of the light of the lamp bead 4. When the tape 3 is drawn out to the end point of the object to be measured, the lamp bead switch 7 can be released, the spring 74 pops up, and drives the conductive block 71 to separate and disconnect from the conductive sheet 1 42 and the conductive sheet 2 43 respectively, and the lamp bead 4 goes out. Since the scale lines of the tape 3 are all illuminated by the lamp bead 4 when the tape 3 is drawn out, the fluorescent scale lines on the tape 3 can be clearly displayed.

[0031] The finger that releases the lamp bead switch 7 is moved into the groove 10 of the brake button 82, and the brake button 82 is pushed. The brake button 82 drives the brake block 81 to abut against one side of the tape 3, and the other side of the tape 3 abuts against the abutment block 9, locking the position of the tape 3 to prevent the tape 3 from retracting. At this time, the scale line reading of the object being measured can be recorded through the fluorescent scale line; if the on-site environment is complex and it is inconvenient to read, press the lamp bead switch 7 when the tape 3 is locked, and illuminate the object being measured through the lamp bead 4 to obtain a clearer reading;

[0032] It should be noted that see Figure 2 , Figure 3 Since the battery 5, the lamp bead 4, the wire 41, the conductive sheet 1 42 and the conductive sheet 2 43 are all fixedly arranged on the inner side of the shell 1, when the brake button 82 and the brake block 81 of the brake assembly slide, it will not affect the connection relationship between the conductive sheet 1 42 and the conductive sheet 2 43. The passage and disconnection of the conductive sheet 1 42 and the conductive sheet 2 43 are affected by the conductive block 71. The conductive sheet 1 42 and the conductive sheet 2 43 have an overlapping length along the sliding direction of the brake block 81, and the sliding stroke of the conductive block 71 is less than the overlapping length of the conductive sheet 1 42 and the conductive sheet 2 43. Therefore, no matter where the brake block 81 slides, the conductive sheet 1 42 and the conductive sheet 2 43 can be controlled by the conductive block 71.

[0033] When the data needs to be re-measured in a short time, there is no need to press the lamp bead switch 7, and it is only necessary to measure again with the help of the fluorescent scale line. When the fluorescent scale line becomes dark, the lamp bead switch 7 can be pressed at any time to supplement the fluorescent scale line with light.

[0034] By arranging a solar panel 6 on the outside of the housing 1, the solar panel 6 charges the battery 5 in the housing 1 to store energy when there is sufficient light, and then the battery 5 supplies power to the lamp bead 4, and the lamp bead 4 can illuminate the fluorescent scale lines on the tape 3 at any time in dim light, thereby improving the fluorescent luminous effect of the tape 3, making the fluorescence of the tape 3 more durable, reducing the dependence on the external ambient light, and making the tape measure more suitable for night use;

[0035] The button 73 of the lamp bead switch 7 is arranged on the brake button 82, and it is more convenient and quick to use fingers to brake the ruler tape 3 and start the switch operation of the lamp bead 4, and the measurement can be completed without the cooperation of multiple people;

[0036] The brake button 82 is provided with a groove 10, and the brake button 82 is operated by the finger in the groove 10 to lock the tape 3. The finger position is limited by the groove 10, avoiding erroneous operation caused by the finger contacting the button 73 of the lamp switch 7, and the night tape measure is convenient and reliable to use.

Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
