Technical Field

[0001] This utility model belongs to the field of level measurement technology, and in particular relates to a levelness measuring device. Background Technology

[0002] Levelness refers to the degree of parallelism between an actual plane and the geoid, and it can be applied to various engineering projects. Levelness measuring devices require support brackets during use. Existing levelness measuring devices have a relatively small measurable range after being fixed in place; to expand the range, they need to be moved to the next location for measurement. After moving, the levelness of the measuring equipment needs to be readjusted, causing inconvenience for users. Utility Model Content

[0003] In view of this, the present invention aims to provide a levelness measuring device to solve the above problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

The bracket is horizontally positioned, and a slide rail is provided on the upper surface of the bracket, on which the levelness measuring instrument is slidably mounted. Two support legs are respectively positioned below both ends of the bracket. Each support leg includes a first connecting section, a second connecting section, a threaded ring, a support rod, a slide rod, a baffle, a slip ring, and a spring. The first connecting section is connected to the lower part of the bracket. The upper end of the second connecting section has a first threaded section, and the lower end of the second connecting section has a second threaded section. The first threaded section is inserted into and screwed onto the first connecting section. The threaded ring is sleeved on and screwed onto the second threaded section.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] As shown in the figure, a levelness measuring device includes a bracket 1, a levelness measuring instrument 2, and support legs 3. The bracket 1 is horizontally positioned, and a slide rail 11 is provided on the upper surface of the bracket 1. The levelness measuring instrument 2 is slidably mounted on the slide rail 11. There are two support legs 3, which are respectively located below both ends of the bracket 1. Each support leg 3 includes a first connecting section 31, a second connecting section 32, a threaded ring 33, a support rod 34, a sliding rod 35, a baffle 36, a slip ring 37, and a spring 38. The first connecting section 31 is connected to the lower part of the bracket 1, and the upper end of the second connecting section 32 is provided with a first threaded section 321. The lower end of the second connecting section 32 is provided with a second threaded section 322. The first threaded section 321 is inserted into the first connecting section 31 and screwed to the first connecting section 31. The threaded ring 33 is sleeved on the second threaded section 322 and screwed to the second threaded section 322. Three support rods 34 are hinged on the side wall of the threaded ring 33. A slide rod 35 is also connected below the second connecting section 32. A baffle 36 and a slip ring 37 are sequentially sleeved on the slide rod 35 from top to bottom. The baffle 36 is fixed on the slide rod 35 by a fixing structure. A spring 38 is sleeved on the slide rod 35 below the slip ring 37.

[0025] The levelness measuring instrument is slidably mounted on the support, allowing for a wider measurement range from the same position and reducing the number of times the device needs to be moved. The outriggers consist of a first connecting section and a second connecting section connected by threads, allowing for adjustment of the outrigger length. The threaded ring on the second connecting section also connects to three support rods. When the support rods are extended, they support the ground, increasing the stability of the support. The position and opening angle of the support rods can also be adjusted via the threaded ring, thereby adjusting the levelness of the support and the stability of the outriggers.

[0026] For example, the baffle 36 is threadedly connected to the slide bar 35.

[0027] Alternatively, fastening bolts are screwed onto the side wall of the baffle 36.

[0028] The baffle can be used to limit the position of the spring. By adjusting the position of the baffle, the extended state of the support rod can be adjusted.

[0029] When the baffle is adjusted to the appropriate position, the support rod unfolds and supports the ground. At the same time, the lower end of the sliding rod also contacts the ground for support, increasing the contact points with the ground and improving stability.

[0030] For example, the upper end of the first connecting segment 31 is hinged to the bracket 1, and the hinge is fixed by a fastening bolt 6. The hinge method facilitates the storage of the support leg, and the fastening bolt is used to fix the support leg.

[0031] For example, the lower surface of the bracket 1 is provided with a groove 12 to facilitate the concealment of the support leg 3.

[0032] Specifically, the lower surface of the bracket 1 is also provided with a movable plate 5 that blocks the outside of the groove 12, and the movable plate 5 is slidably disposed. The movable plate can be used to confine the support leg within the groove to prevent the support leg from coming out of the groove when stored or moved.

[0033] More specifically, there are two movable plates 5, and the side wall of the bracket 1 is provided with a sliding groove 13, in which the movable plates 5 are slidably disposed. When storing, the movable plates can be moved to the side opposite to the support legs, making it convenient for storing or using the support legs.

[0034] For example, it also includes elastic rings 4, with three elastic rings 4 set on the outside of the support rod 34 to fix the support rod 34. Due to the action of the spring, the support rod is in an unfolded state, which is not convenient for storage. The elastic rings can fix the closed support rod, making it convenient for storage.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
