Description

Technical Field

[0001] The utility model relates to the technical field of engineering measurement, in particular to a tower ruler for construction measurement which can prevent misoperation. Background Art

[0002] A tower ruler is a type of level ruler. Early level rulers were mostly made of wood, which was heavy and limited in length, making it inconvenient to carry when measuring. Later, they were gradually made of lightweight and high-strength materials such as aluminum alloy. They adopt a tower-shaped retractable form, which is convenient to pull out when in use. The range of a single elevation measurement is greatly improved. It can be retracted when carried. Because of its shape similar to a tower, it is often called a tower ruler.

[0003] In the existing leveling construction, mature professionals are needed to cooperate skillfully to prevent mistakes, resulting in two professionals being able to do only one thing, which will lead to serious occupation of talent resources; in actual construction, due to progress and cost reasons, non-professional workers are often asked to hold a ruler to cooperate in measurement. Due to the high turnover of personnel, lack of business proficiency, and uneven degree of cooperation, the ruler is often not pulled out in place or pulled out too much, and this situation is not easy to be discovered. The existing ruler cannot intuitively see whether the ruler holder's operation is standardized, nor can it track and judge the ruler status in real time during the construction process. During the construction process, the professional surveyors and the ruler holders are far apart, and the surveyors cannot find problems in time and make mistakes, which may even lead to serious quality accidents.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. The construction measuring scale which prevents misoperation has a pressure cap which pops out during the process of withdrawing the inner scale to make the first contact ring and the second contact ring contact, and then the indicator light is powered by the battery box, so that the surveying personnel can judge the normal operation specification state of the scale by observing the brightness of the indicator light during long-distance observation, and can timely discover whether the scale has errors caused by misoperation, thereby avoiding serious quality accidents.

[0021] 2. The construction measuring scale that prevents misoperation is designed to make the use status of the scale observable through the brightness of the indicator light, so that situations such as the scale being not pulled out properly or being pulled out too much can be observed by professionals at a long distance, and the person holding the scale can be notified to re-operate the scale, thereby reducing the demand for professionals during measurement. Even if the person holding the scale is not proficient in the business and the degree of cooperation is uneven due to the high turnover of personnel, the measurement can be continued with the help of another professional.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-3 A construction measuring tower ruler for preventing misoperation includes a ruler mechanism and a misoperation prompt mechanism, wherein the ruler mechanism includes:

[0028] The outer ruler 1 and the inner ruler 2 of the ruler mechanism are formed by the socket-and-spigot combination section by section;

[0029] A buckle groove 3 is provided on the outer ruler 1 and the inner ruler 2 near the bottom end surface; and

[0030] An indicator light 4 embedded in the inner ruler 2;

[0031] The misoperation prompting mechanism includes: a storage box 6 installed inside the inner ruler 2;

[0032] A pressing cap 5 is slidably received in the inner ruler 2 and is engaged with the inner buckle groove 3 of the outer ruler 1 via a through groove 10 provided on the inner ruler 2 near the bottom surface; and

[0033] A battery box 11 installed inside the inner ruler 2;

[0034] The inner wall of the storage box 6 is provided with a second contact ring 9 , and the outer edge of the pressure cap 5 located inside the storage box 6 is provided with a first contact ring 8 .

[0035] Among them, a spring 7 is arranged inside the pressure cap 5, and one end of the spring 7 away from the pressure cap 5 is arranged on the inner wall of the storage box 6. The spring 7 is provided to give the pressure cap 5 power to bulge outward, so that the pressure cap 5 bulges outward after the inner ruler 2 moves to the specified position, and then the indicator light 4 is powered, so that the remote observation professionals can judge whether the operation of the tower ruler is standardized.

[0036] Among them, the negative pole of the indicator light 4 is connected to the battery box 11 through a wire, a hidden wire groove is set in the inner wall of the inner ruler 2, and the wire is fitted in the wire groove of the inner wall of the inner ruler 2, so that another set of socket rulers can be added to the inner ruler 2.

[0037] Among them, the positive pole of the indicator light 4 is connected to the second contact ring 9 through a wire. The positive wire of the indicator light 4 is connected to the second contact ring 9, so that the battery box 11 is in a disconnected state before the pressure cap 5 reaches the buckle groove 3. Only when it reaches the specified position can it be powered through the second contact ring 9.

[0038] Among them, the pressure cap 5 and the storage box 6 are both made of insulating materials. The pressure cap 5 and the storage box 6 are used to limit the electricity transmitted from the battery box 11 to the inside of the storage box 6 to avoid electric shock to the person holding the ruler. At the same time, the range of current flow is reduced to save power loss.

[0039] Among them, the first contact ring 8 is electrically connected to the positive pole of the battery box 11 through a wire, and a sufficient discontinuity distance is formed between the first contact ring 8 and the second contact ring 9, so that the indicator light 4 can be powered off by pressing the pressure cap 5, and then the indicator light 4 is in a standby state when the outer ruler 1 and the inner ruler 2 are in a retracted state, thereby avoiding the tower ruler consuming power from the battery box 11 when being stored.

[0040] Among them, the bottom of the second contact ring 9 is arc-shaped, and the first contact ring 8 overlaps the bottom of the second contact ring 9. After the pressure of the pressure cap 5 disappears, the outer edge of the first contact ring 8 directly contacts the arc-shaped surface of the second contact ring 9 under the action of the spring 7, and the arc-shaped contact surface of the second contact ring 9 can ensure that the first contact ring 8 tends to the middle position after contact, and there is always a point of contact with the second contact ring 9.

[0041] Working principle: when using the tower ruler, the inner ruler 2 is pulled out from the outer ruler 1. After the pressure cap 5 reaches the predetermined position, the pressure force disappears and the pressure cap 5 is pushed out from the inside of the through groove 10 by the spring 7. At the same time, the first contact ring 8 contacts the second contact ring 9 as the pressure cap 5 is pushed out, so that the positive and negative poles of the indicator light 4 are in contact with the positive and negative poles of the battery box 11 through the conductive material, thereby achieving the effect of powering the indicator light 4.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
