Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a portable insulation gap measuring ruler. Background Art

[0002] A gap measuring ruler is a tool used to measure the size of the gap between objects. It is mostly used in industrial production to ensure assembly accuracy and inspect processing quality. It is also used in industries such as automobile maintenance and construction engineering. It has a wide range of uses. However, the gap measuring rulers currently used are inconvenient to carry because of their long size and sharp tip, which can easily cause accidental injuries. Therefore, we propose a portable insulation gap measuring ruler. Utility Model Content

[0003] The main purpose of the utility model is to provide a convenient insulation gap measuring ruler, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A portable insulation gap measuring ruler comprises an upper measuring ruler, a storage bin is fixedly mounted on the rear surface of the upper measuring ruler, a carrying ring is fixedly mounted on the upper end of the upper measuring ruler, a lower measuring ruler is movably mounted on the output end of the storage bin, and a knob-type spiral sleeve is spirally mounted on the surface of the lower measuring ruler.

[0006] Preferably, a retractable sliding opening is provided on the rear surface of the storage bin.

[0007] Preferably, a screw rod is fixedly mounted on the rear surface of the lower measuring ruler near the upper end.

[0008] Preferably, the spiral rod passes through the contraction slide and is spirally connected to the knob-type spiral sleeve.

[0009] Preferably, the front surfaces of the upper measuring ruler and the lower measuring ruler are both printed with scale lines.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In the utility model, the portable insulation gap measuring ruler can completely store the lower measuring ruler inside the storage compartment and fix it by screwing the knob-type spiral sleeve, thereby reducing the length of the ruler when carried and preventing the tip of the lower measuring ruler from poking or scratching the human body, which is safer and more reliable.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0017] like Figure 1-3 As shown, a portable insulation gap measuring ruler includes an upper measuring ruler 1, a storage compartment 3 is fixedly mounted on the rear surface of the upper measuring ruler 1, a carrying ring 2 is fixedly mounted on the upper end of the upper measuring ruler 1, a lower measuring ruler 4 is movably mounted on the output end of the storage compartment 3, and a knob-type spiral sleeve 5 is spirally mounted on the surface of the lower measuring ruler 4;

[0018] A retractable slide 31 is provided on the rear surface of the storage bin 3; a spiral rod 41 is fixedly installed on the rear surface of the lower measuring ruler 4 near the upper end; the spiral rod 41 passes through the retractable slide 31 and is spirally connected to the knob-type spiral sleeve 5; the front surfaces of the upper measuring ruler 1 and the lower measuring ruler 4 are both printed with scale lines, which are used for measurement. When the spiral rod 41 is pushed to the bottom end of the retractable slide 31, the scale lines on the lower measuring ruler 4 are just connected with the scale lines on the upper measuring ruler 1 in length, and there is no dimensional error.

[0019] It should be noted that the present invention is a convenient insulation gap measuring ruler. When in use, the user screws the knob-type spiral sleeve 5 to loosen it, and then pushes it downward, so that the spiral rod 41 drives the lower measuring ruler 4 to extend from the lower end of the storage bin 3 until the spiral rod 41 is pushed to the very end of the contraction slide 31, and then screws the knob-type spiral sleeve 5 to press it tightly against the edge of the contraction slide 31 to fix it, thereby fixing 4 for measurement use. When not in use, it is retracted into the storage bin 3 for storage and fixation, thereby reducing its length and space occupation, making it more convenient to carry, and preventing the tip of the lower measuring ruler 4 from hurting people, which is safe and practical.

[0020] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
