[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] Example: Refer to Figures 1 to 5 A level ruler for decoration measurement includes a level ruler body 1, a slide groove 11 is provided inside the level ruler body 1, an auxiliary rod 2 is slidably connected to the opposite side of the slide groove 11, a gear 12 is rotatably connected to the middle of the slide groove 11, a rack 21 is fixedly installed on the opposite side of the two auxiliary rods 2, and the two racks 21 are meshed with the gear 12, a connecting block 22 is fixedly installed on the opposite side of the two auxiliary rods 2, and a grip groove 23 is provided on one side of the two connecting blocks 22, a locking mechanism is provided inside the level ruler body 1, and the locking mechanism directly acts on the auxiliary rod 2, when not in use, The auxiliary rods 2 on both sides are retracted into the inside of the slide groove 11, and the auxiliary rods 2 are fixed by using the locking mechanism, so that the length of the entire device can be reduced, which is convenient for the staff to carry. When the auxiliary rods 2 on both sides need to be used during the measurement process, the locking mechanism is first controlled to no longer fix the auxiliary rods 2. Since the racks 21 set on one side of the two auxiliary rods 2 are meshed and connected with the gear 12, when one auxiliary rod 2 is pulled to move, the other auxiliary rod 2 moves at the same time, and the movements of the two auxiliary rods 2 are opposite. At this time, the two auxiliary rods 2 can be unfolded to increase the measuring length of the device.

[0024] The locking mechanism includes a driving rod 3 movably passing through the front wall of the level ruler body 1, and a fixing block 31 is fixedly installed at the end of the driving rod 3, and a spring 32 is provided on the outside of the driving rod 3 and inside the level ruler body 1. A plurality of fixing holes 33 are opened on one side of one auxiliary rod 2, and the fixing block 31 is engaged with the fixing holes 33. The elastic force of the spring 32 is used to push the fixing block 31 toward one side of the auxiliary rod 2 and insert it into the corresponding fixing hole 33, so that the auxiliary rod 2 can be fixed. According to actual needs, the fixing block 31 is inserted into the fixing holes 33 at different positions to avoid the auxiliary rod 2 sliding back and forth during use, thereby improving the stability of the device during measurement.

[0025] The inner part of one of the connecting blocks 22 is rotatably connected with a rotating shaft 4, and the outer side of the rotating shaft 4 is fixedly installed with a connecting rod 41, and the rotating shaft 4 is slidably connected with the connecting block 22 and the level ruler body 1. A groove 42 is provided on one side of the rotating shaft 4, and a spring 2 43 is fixedly installed inside the groove 42, and a clamping block 44 is fixedly installed at the other end of the spring 2 43. Two clamping holes 45 are provided inside the connecting block 22, and the clamping block 44 is clamped with the clamping hole 45. Under normal circumstances, the connecting rod 41 is inside the level ruler body 1 and is in a horizontal state with it. At the same time, the elastic force of the spring 2 43 is used to push the clamping block 44 to clamp with the clamping hole 45, so that the connecting rod 41 can be fixed. When it is necessary to measure a right angle, the protrusion on one side of the clamping block 44 is moved toward the other side so that it is no longer clamped with the clamping hole 45, and then the connecting rod 41 is rotated until it is in a vertical state with the level ruler body 1. At this time, the rebound force of the spring 2 43 pushes the clamping block 44 to clamp with the clamping hole 45 again, so as to fix the connecting rod 41, which is convenient for the staff to measure.

[0026] Rollers 5 are fixedly installed on the opposite sides of the two auxiliary rods 2. Two limit cavities 51 are opened inside the level body 1, and the two rollers 5 are respectively slidably connected with the two limit cavities 51 to facilitate the sliding of the auxiliary rod 2. The level body 1 and the two auxiliary rods 2 are made of aluminum alloy, which can reduce the weight of the whole equipment without reducing the hardness, and is convenient for staff to carry. The thickness and height of the level body 1 are consistent with the two connecting blocks 22, so that the connecting blocks 22 can be flush with the level body 1, thereby improving the stability of the level.

[0027] The operating principle of this embodiment is as follows: when in use, the level ruler body 1 can be used to realize the function of horizontal measurement of the wall. When the measured distance is long, the staff pulls the driving rod 3 outward to drive the fixing block 31 at the end to move at the same time, so that it is no longer engaged with the fixing hole 33, thereby being able to move the auxiliary rod 2 outward. During the movement of the auxiliary rod 2, the rack 21 on one side is driven to move at the same time. Since the two racks 21 are engaged with the gear 12, the auxiliary rods 2 on both sides can be moved synchronously in opposite directions, so that the two auxiliary rods 2 can be synchronously unfolded, thereby increasing the measuring length of the level ruler and improving the actual use effect of the device. When it is necessary to measure the right angle of the wall, the protrusion on one side of the clamping block 44 is dragged toward the other side so that it is no longer engaged with the clamping hole 45, thereby being able to rotate the connecting rod 41 so that it is in a vertical state with the level ruler body 1, which is convenient for the staff to perform inspection and improves the functionality of the level ruler.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
