Description

Technical Field

[0001] The utility model belongs to the technical field of detection rulers, and in particular relates to a detection ruler. Background Art

[0002] When the construction site quality inspectors and project managers collect and inspect the data on the construction site, they need to inspect the horizontality of the ground and the verticality of the wall. At present, a spirit level is mostly used for this work. However, in the prior art, the spirit level only has the function of measuring the level. Some spirit levels also have scale lines to measure the length. However, due to the residues left over from the construction, there are often some brittle cement blocks or even a whole large cement layer on the ground and corners. As a result, it is necessary to place the spirit level at the junction of the wall and the ground for measurement. This part of the uneven cement block or cement layer may cause the spirit level to tilt and make it impossible to measure accurately. If you want to knock this part off, you need to carry other tools, which is inconvenient. For this reason, we propose a new multi-functional inspection ruler to solve this problem. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a detection ruler, which can clean the cement blocks adhering to the ground and walls that affect the measurement without carrying other tools, thereby expanding the functionality of the level ruler.

[0004] To achieve the above objectives, the utility model provides the following technical solutions: a detection ruler comprises a ruler body, a gripping portion is provided between the front and back surfaces of the ruler body, a bottom mounting groove is provided at the bottom of the ruler body, an auxiliary cleaning device is slidably installed at the bottom of the bottom mounting groove, a first mounting cavity and a second mounting cavity are provided inside the auxiliary cleaning device, a shifting groove is provided between the first mounting cavity, the second mounting cavity and one side surface of the auxiliary cleaning device, a mounting plate is slidably installed inside the first mounting cavity and the second mounting cavity, one end of the mounting plate is connected with a shifting block, a fixing seat is provided at the bottom of the shifting block, a fixing slot is provided inwardly on the side surface of the fixing seat, a scraper is fixedly installed at the bottom of the mounting plate inside the first mounting cavity, a crushing cone is fixedly installed at the bottom of the mounting plate inside the second mounting cavity, a telescopic cavity is provided inwardly on one side surface of the auxiliary cleaning device, a telescopic rod is inserted and installed inside the telescopic cavity, a spring is sleeved on the outer side of the telescopic rod, one end of the telescopic rod is connected to the connecting plate, and an insert block is provided on one side surface of the connecting plate.

[0005] The beneficial effects of the utility model are as follows: when cement blocks adhere to the ground and wall surfaces to be measured, a scraper or a crushing cone can be selected as needed. Taking the use of a scraper as an example, the push block and the mounting plate are pushed downward through the finger hole on the push block to release the magnetic attraction between the magnetic attraction plate on the mounting plate and the magnetic attraction plate inside the first mounting cavity. When the fixing seat slides to the top of the plug-in block, the connecting plate is pulled outward through the finger ring to make the telescopic rod extend outward from the inside of the telescopic cavity, compressing the spring and moving the plug-in block accordingly. When the plug-in block leaves the bottom of the fixing seat, the fixing seat slides downward. Align the fixed slot with the plug block, then release the finger ring, and under the action of the spring's rebound force, the plug block is inserted into the fixed slot to fix the fixed seat, thereby fixing the scraper. At this time, the cement block can be scraped off with the scraper extended from the first installation cavity. When encountering harder cement blocks, the crushing cone can be taken out of the second installation cavity in the same way, and the cement block can be crushed using the sharper part at the bottom of the crushing cone. Without carrying other tools, the cement blocks that affect measurement and are adhered to the ground and walls can be cleaned, thereby expanding the functionality of the level ruler.

[0006] To take measurements:

[0007] As a further improvement of the above technical solution: a first bubble tube is provided on the inner side of the top of the ruler body, a second bubble tube is provided on the side of the ruler body, and a measuring scale line is provided on the front side of the ruler body.

[0008] The ruler body has the functions of a conventional level ruler, and can measure the levelness through the first bubble tube and the second bubble tube, and can measure the length by setting the measuring scale lines.

[0009] To facilitate the movement of the dial block:

[0010] As a further improvement of the above technical solution: a finger hole is opened inwardly on the side surface of the shift block.

[0011] The beneficial effect of this improvement is that the finger hole facilitates the shifting of the shifting block, and the finger can be inserted into the finger hole when shifting.

[0012] To prevent the mounting plate from sliding during use:

[0013] As a further improvement of the above technical solution: the inner top walls of the first installation cavity, the second installation cavity and the top of the installation plate are all provided with magnetic attraction plates.

[0014] The beneficial effect of this improvement is that the first mounting cavity and the mounting plate, as well as the second mounting cavity and the mounting plate, are magnetically fixed by means of magnetic plates, thereby preventing the mounting plates from sliding during use.

[0015] To facilitate replacement of the auxiliary cleaning device:

[0016] As a further improvement of the above technical solution: a countersunk screw hole is passed through the front side of the ruler body and the inner side of the bottom mounting groove, a screw hole is also opened on the front side of the auxiliary cleaning device, and the ruler body and the auxiliary cleaning device are fixed by connecting the countersunk screw hole and the screw hole with a locking screw.

[0017] The ruler body and the auxiliary cleaning device are fixed by connecting the countersunk screw hole and the screw hole with a locking screw. When a new auxiliary cleaning device needs to be replaced, the auxiliary cleaning device can be slid out along the bottom mounting groove for replacement by unscrewing the locking screw.

[0018] To pull the connecting plate:

[0019] As a further improvement of the above technical solution: a finger ring is pinned on the other side of the connecting plate.

[0020] The finger ring is used to pull the connecting plate to move.

[0021] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

A spring 20 is sleeved on the outer side of the telescopic rod 21, and one end of the telescopic rod 21 is connected to a connecting plate 22, and a plug block 23 is provided on one side of the connecting plate 22.

[0031] When cement blocks adhere to the ground and wall to be measured, the scraper 17 and the crushing cone 18 can be selected as needed. Taking the use of the scraper 17 as an example, the shifting block 12 and the mounting plate 11 are shifted downward through the finger hole 13 on the shifting block 12 to release the magnetic attraction between the magnetic attraction plate 16 on the mounting plate 11 and the magnetic attraction plate 16 inside the first mounting cavity 8. When the fixing seat 14 slides to the top of the plug-in block 23, the connecting plate 22 is pulled outward through the finger ring 24, so that the telescopic rod 21 extends outward from the inside of the telescopic cavity 19, compressing the spring 20, and the plug-in block 23 also moves accordingly. When the plug-in block 23 leaves the bottom of the fixing seat 14, the fixing seat 14 moves downward. Slide to align the fixed slot 15 with the insert block 23, then release the finger ring 24, and under the action of the rebound force of the spring 20, the insert block 23 is inserted into the fixed slot 15 to fix the fixed seat 14, thereby fixing the scraper 17. At this time, the cement block can be scraped off by the scraper 17 extending from the first installation cavity 8. When encountering harder cement blocks, the crushing cone 18 can be taken out of the second installation cavity 9 in the same way, and the cement block can be crushed by the sharper part at the bottom of the crushing cone 18. Without carrying other tools, the cement blocks that affect the measurement and adhere to the ground and walls can be cleaned, thereby expanding the functionality of the level ruler.

[0032] A first bubble tube 3 is provided on the inner side of the top of the ruler body 1 , a second bubble tube 4 is provided on the side of the ruler body 1 , and a measuring scale line 5 is provided on the front of the ruler body 1 .

[0033] The ruler body 1 has the functions of a conventional level ruler, and can measure the levelness through the first bubble tube 3 and the second bubble tube 4, and can measure the length through the setting of the measuring scale line 5.

[0034] A finger hole 13 is formed inwardly on the side surface of the shifting block 12 .

[0035] The finger hole 13 facilitates the movement of the shifting block 12 , and the finger can be inserted into the finger hole 13 during the movement.

[0036] The inner top walls of the first installation cavity 8 , the second installation cavity 9 and the top of the installation plate 11 are all provided with magnetic attraction plates 16 .

[0037] The first mounting cavity 8 and the mounting plate 11 as well as the second mounting cavity 9 and the mounting plate 11 are fixed by magnetic attraction through the magnetic attraction plate 16 to prevent the mounting plate 11 from sliding during use.

[0038] A countersunk screw hole penetrates between the front side of the ruler body 1 and the inner side of the bottom mounting slot 6, and a screw hole is also opened on the front side of the auxiliary cleaning device 7. The ruler body 1 and the auxiliary cleaning device 7 are fixed by connecting the countersunk screw hole and the screw hole with a locking screw 25.

[0039] The ruler body 1 and the auxiliary cleaning device 7 are fixed by connecting the countersunk screw hole and the screw hole with a locking screw 25. When a new auxiliary cleaning device 7 needs to be replaced, the locking screw 25 can be unscrewed to slide the auxiliary cleaning device 7 along the bottom mounting slide groove 6 for replacement.

[0040] A finger ring 24 is pinned to the other side of the connecting plate 22 .

[0041] The finger ring 24 is used to pull the connecting plate 22 to move.

[0042] Working principle and use process of the utility model: when the device is used, the ruler body 1 has the functions of a conventional level ruler, and the levelness can be measured through the first bubble tube 3 and the second bubble tube 4.
