DETAILED DESCRIPTION

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 As shown, a right-angle measuring ruler for internal and external angles in building construction includes a main ruler 1, a measuring instrument 2 fixedly connected to the upper surface of the main ruler 1, a secondary ruler 3 rotatably connected to the inner cavity of the right part of the main ruler 1, a protective component 4 fixedly connected to the front of the secondary ruler 3, a fixing component 5 overlapping the left side of the protective component 4, and the rear of the fixing component 5 fixedly connected to the front of the main ruler 1.

[0028] First, under the action of the protective component 4 and the fixing component 5, the auxiliary ruler 3 can be firmly fixed in the inner wall of the main ruler 1. When it is needed, simply open the fixing component 5 so that the auxiliary ruler 3 can rotate along the rear part of the main ruler 1 under the action of the protective component 4, thereby performing the detection of the inner and outer right angles under the action of the detector 2.

[0029] like Figure 2 , Figure 3 As shown, the fixing component 5 includes a second fixing block 51, the rear of which is fixedly connected to the front of the main scale 1, and a second protective rubber sleeve 52 is fixedly connected to the outer wall of the second fixing block 51, the rear of which is fixedly connected to the front of the main scale 1; the protective component 4 includes a first fixing block 41, the rear of which is fixedly connected to the front of the auxiliary scale 3, and a first protective rubber sleeve 42 is fixedly connected to the outer wall of the first fixing block 41, the inner wall of the rear part of the first protective rubber sleeve 42 is fixedly connected to the outer wall of the auxiliary scale 3, and the left side of the first protective rubber sleeve 42 overlaps with the right side of the second fixing block 51.

[0030] The front sections of the auxiliary ruler 3 and the fixing component 5 are protected by the fixing block 41 and fixing block 51. At the same time, the upper and lower sides of the protective rubber sleeve 42 are provided with grooves, which makes it easy for the user to move the auxiliary ruler 3 during use, thereby improving the user's feel and providing protection.

[0031] like Figure 4 As shown, a movable block 53 is movably sleeved in the inner cavity of the right part of the fixed block 2 51. The right part of the outer wall of the movable block 53 is movably sleeved in the inner cavity of the left part of the fixed block 1 41. A movable rod 54 is fixedly connected to the left side of the movable block 53. A limiting seat 55 is slidably connected to the left part of the outer wall of the movable rod 54. The lower surface of the limiting seat 55 is fixedly connected to the bottom of the inner cavity of the fixed block 2 51. A limiting block 1 57 is fixedly connected to the left side of the movable rod 54 and the limiting block 1 57 is located on the left side of the limiting seat 55.

[0032] Through the action of the limiting seat 55 and the moving rod 54, the moving block 53 can move stably left and right in the inner cavity of the right part of the fixed block 51, thereby playing a guiding role.

[0033] Protective pads 59 are fixedly connected to both sides of the limiting block 57, and the outer walls of the two protective pads 59 are respectively movably connected to the inner cavity of the fixing block 51.

[0034] The protective pad 59 prevents the limiting block 57 from colliding with the inner cavity of the fixing block 51 when it moves under the action of the spring 56, thus providing a buffering and protective function.

[0035] like Figure 5 , Figure 7 As shown, the outer wall of the limiting block 57 is movably sleeved with the inner cavity of the fixed block 51. The front of the limiting block 57 is fixedly connected to the push block 58, which is located in front of the fixed block 51. The inner cavity of the moving block 53 is fixedly connected to two guide rods 515. The outer walls of the front and rear parts of the two guide rods 515 are slidably connected to two locking blocks 510. The outer walls of the two locking blocks 510 are slidably connected to the inner cavities of the front and rear parts of the moving block 53, respectively. The outer walls of the opposite parts of the two locking blocks 510 are respectively locked with the inner cavity of the left part of the fixed block 41. The opposite surfaces of the upper and lower parts of the two locking blocks 510 are fixedly connected to springs 516. The opposite surfaces of the four springs 516 are respectively fixedly connected to the front and rear sides of the middle part of the two guide rods 515. The inner walls of the four springs 516 are movably sleeved with the outer walls of the front and rear parts of the two guide rods 515, respectively.

[0036] By pushing the push block 58, the limiting block 57 can push the moving rod 54 to the right under the guidance of the limiting seat 55, thereby moving the moving block 53 to the right into the inner cavity of the fixed block 41. At this time, under the action of the spring 516, the two locking blocks 510 can be locked into the inner cavity of the fixed block 41, thereby restricting and fixing the moving block 53 in the inner cavity of the fixed block 41, which facilitates quick fixing and is easy to operate.

[0037] Spring 56 is movably sleeved on the outer wall of the right part of the moving rod 54. The left side of spring 56 is fixedly connected to the right side of the limiting seat 55. The right side of spring 56 is fixedly connected to the left side of the moving block 53. Pull rope 511 is fixedly connected to the opposite face of the middle of the two locking blocks 510. The outer wall of the left part of the pull rope 511 is slidably connected to the inner cavity of the moving block 53 and the moving rod 54 respectively. Limiting block 512 is fixedly connected to the left side of the pull rope 511. Limiting block 512 is located to the left of limiting block 57. The outer wall of limiting block 512 is slidably connected to the inner cavity of fixed block 51. Push block 513 is fixedly connected to the front of limiting block 512. Push block 513 is located in front of fixed block 51.

[0038] By moving the push block 2 513, the limit block 2 512 can pull the pull rope 511 to the left, so that the two locking blocks 510 can move towards each other under the action of the guide rod 515. When the two locking blocks 510 move into the inner cavity of the moving block 53, the moving block 53 can move back into the inner cavity of the fixed block 2 51 under the action of the spring 1 56, so as to facilitate quick opening and use.

[0039] like Figure 6 As shown, auxiliary wheels 514 are attached to the front and rear sides of the right part of the pull rope 511, and the two auxiliary wheels 514 are located on the left side of the guide rod 515. The outer walls of the upper and lower parts of the two auxiliary wheels 514 are rotatably connected to the inner cavity of the moving block 53.

[0040] The movement of the pull rope 511 is restricted by the action of the two auxiliary wheels 514, thereby playing a role in auxiliary guidance.

[0041] The working principle of this utility model is as follows: First, by moving the second push block 513, the second limit block 512 can pull the pull rope 511 to the left, thereby allowing the two locking blocks 510 to move towards each other under the action of the guide rod 515. When the two locking blocks 510 move into the inner cavity of the moving block 53, the moving block 53 can then move back into the inner cavity of the second fixed block 51 under the action of the first spring 56. At this time, by moving the first protective rubber sleeve 42, the auxiliary ruler 3 can rotate along the rear part of the main ruler 1 under the action of the protective component 4, thereby... The inner and outer right angles are tested under the action of the detector 2. After use, the auxiliary ruler 3 is moved back into the inner cavity of the main ruler 1. By pushing the push block 58, the limiting block 57 can push the moving rod 54 to the right under the guidance of the limiting seat 55, so that the moving block 53 moves to the right into the inner cavity of the fixed block 41. At this time, under the action of the spring 516, the two locking blocks 510 can be locked into the inner cavity of the fixed block 41, so that the moving block 53 is restricted and fixed in the inner cavity of the fixed block 41, thus facilitating quick fixation.
