DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-5 As shown, a granite ruler protection device comprises a protection box 1, the inner wall of the protection box 1 is provided with a plurality of evenly arranged square grooves 2, the inner walls of the plurality of square grooves 2 are rotatably connected with shafts 3, the outer walls of the plurality of shafts 3 are fixedly connected with rollers 4, the outer walls of the plurality of rollers 4 are fixedly connected with rubber rings 5, when the rubber rings 5 ​​roll, they will roll synchronously with the rollers 4, a telescopic column 6 is slidably penetrated at one end of the protection box 1, a baffle 7 is fixedly connected at one end of the telescopic column 6, a ruler body 8 is fixedly connected at the other end of the telescopic column 6, the ruler body 8 is a granite ruler, the ruler body 8 is in contact with the rubber ring 5, when the ruler body 8 is used, the baffle 7 is pushed and the ruler body 8 is separated from the protection box 1 under the action of the telescopic column 6, and the baffle 7 can prevent the ruler body 8 and the rubber ring 5 from separating.

[0025] In this embodiment, a box door 11 is provided at the other end of the protection box 1, and a first rubber pad 12 matching the shape of the inner wall of the protection box 1 is fixedly connected to one end of the box door 11 close to the protection box 1;

[0026] The ruler body 8 can be stored in the protective box 1 through the box door 11, and the first rubber pad 12 will squeeze and contact the ruler body 8, so as to limit the ruler body 8 and prevent shaking during movement and avoid bumping.

[0027] In this embodiment, a second rubber pad 13 is fixedly connected to one side of the inner wall of the protection box 1 corresponding to the square groove 2, and the second rubber pad 13 is arranged on the outer wall of the telescopic column 6;

[0028] The telescopic column 6 passes through the second rubber pad 13. When in use, the telescopic column 6 can be used to control the straightedge body 8 to extend out of the protective box 1 and be used for measurement. The second rubber pad 13 cooperates with the first rubber pad 12 and the rubber ring 5 to further limit and fix the straightedge body 8 to prevent shaking.

[0029] In this embodiment, both sides of the top of the protection box 1 are fixedly connected with fixed blocks 9, and the two fixed blocks 9 are rotatably connected with fixed connecting plates 10 at one end close to each other, and the two fixed connecting plates 10 are fixedly connected to the box door 11;

[0030] The box door 11 can be turned over to the top of the protection box 1 by the fixing block 9 and the fixing connecting plate 10 to avoid excessive influence on the use.

[0031] In this embodiment, the ends of the fixed connecting plates 10 that are away from each other are fixedly connected with connecting plates 15, and one end of the two connecting plates 15 is fixedly connected with triangular clamping blocks 16, and there is an elastic plate between the triangular clamping blocks 16 and the connecting plates 15. The two ends of the protective box 1 are fixedly connected with a fixed ring 14 on one side corresponding to the connecting plate 15, and the triangular clamping blocks 16 are clamped on the fixed ring 14;

[0032] When the box door 11 is to be closed, the inclined surface on the triangular clamping block 16 will first contact the fixing ring 14 and bend. When the box door 11 is completely closed, the triangular clamping block 16 will be stuck on the fixing ring 14 under the action of elasticity, completing the limiting fixation of the box door 11, and then completing the limiting fixation of the level ruler body 8.

[0033] In this embodiment, the square groove 2 is symmetrically distributed about the center line of the protective box 1, the second rubber pad 13 and the first rubber pad 12 are of the same shape and size and can contact the straightedge body 8 in all directions, and the second rubber pad 13 and the first rubber pad 12 are in close contact with each other.

[0034] It should be noted that the utility model is a granite ruler protection device. When in use, when the ruler body 8 moves back and forth in the protection box 1, it moves along the outer surface of the rubber ring 5 and causes the rubber ring 5 to rotate, thereby reducing the friction of the ruler body 8 when moving back and forth, thereby reducing the wear of the ruler body 8, and thus maintaining the brightness and beauty;

[0035] When not in use, the ruler body 8 can be stored in the protective box 1. At this time, the box door 11 is flipped over and covered on the opening of the protective box 1 so that the first rubber pad 12 is stuck into the inner wall of the protective box 1. At the same time, the triangular clamping block 16 is stuck on the fixing ring 14 to complete the limit fixation of the box door 11, and the ruler body 8 is limited by the cooperation of the second rubber pad 13 and the rubber ring 5 to prevent the ruler body 8 from shaking in the protective box 1 during carrying, thereby avoiding bumps on the ruler body 8, and then avoiding breakage, thereby extending the service life.
