Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses a fixed portable frame of spirit level convenient to leveling. Referring to fig. 1, the fixed portable frame of spirit level is provided with backup pad 2 including fixing base 1 that is used for installing the spirit level below fixing base 1, and the lower fixed surface of backup pad 2 is connected with lifter 3, and the side of lifter 3 is connected with three supporting legs 4 that support in ground, and three supporting legs 4 are around the axis evenly distributed of lifter 3.

Referring to fig. 1, a supporting spring 11 is disposed between the fixing base 1 and the supporting plate 2, and upper and lower ends of the supporting spring 11 are respectively fixedly connected to the lower surface of the fixing base 1 and the upper surface of the supporting plate 2. Be connected with locking Assembly 5 between fixing base 1 and the backup pad 2, locking Assembly 5 locks each other between fixing base 1 and the backup pad 2 to restriction fixing base 1 and backup pad 2 take place relative displacement.

When leading to whole this portable slope of putting up because the ground slope, fixing base 1 is the tilt state also, can become flexible locking Assembly 5 this moment to adjust fixing base 1 and be comparatively horizontally state, pass through locking Assembly 5 with fixing base 1 and backup pad 2 again and lock. The fixing base 1 of the adjustable installation level is in a horizontal state.

Referring to fig. 2, since the spring does not move in a direction, in order to reduce the possibility of lateral movement of the fixing base 1 when the fixing base 1 is adjusted, a guide assembly 6 for guiding the adjustment of the fixing base 1 is connected to the fixing base 1.

Referring to fig. 2, the guiding assembly 6 includes at least three guiding rods 61, four guiding rods 61 in this embodiment, evenly distributed and ball-hinged with the lower surface of the fixing base 1. The guide rod 61 is in the shape of a quadrangular prism, a guide hole 62 penetrating the support plate 2 is formed in the upper surface of the support plate 2, and the guide rod 61 penetrates through the guide hole 62. When adjusting fixing base 1 and making fixing base 1 tend to the level, guide bar 61 plays the guide effect for fixing base 1's regulation along guiding hole 62 up-and-down motion, prevents that fixing base 1 from taking place the displacement of horizontal direction.

Referring to fig. 3, the locking assembly 5 includes four fixing blocks 51 fixedly connected to the lower surface of the support plate 2, a connecting hole 52 penetrating through the fixing block 51 is formed in the lower surface of each fixing block 51, and the axis of each connecting hole 52 is located on the same vertical line as the axis of the adjacent guide hole 62. Each guide rod 61 penetrates through the adjacent connecting holes 52, the side wall of each fixing block 51 is in threaded connection with a supporting rod 53, and the supporting rods 53 penetrate through the side wall of the fixing block 51 and are tightly supported with one side wall of each guide rod 61.

Referring to fig. 2 and 3, when the fixing base 1 needs to be adjusted, the abutting rod 53 on each fixing block 51 is loosened, the abutting rod 53 is separated from the guide rod 61, and then the fixing base 1 can be adjusted to enable the fixing base 1 to tend to be horizontal. Finally, the abutting rods 53 are screwed, so that each abutting rod 53 abuts against the guide rod 61.

Referring to fig. 1, the elevating rod 3 includes a threaded rod 31 connected to the lower surface of the supporting plate 2, the threaded rod 31 being disposed vertically downward, and a sleeve 32 being threadedly connected to the outer side of the threaded rod 31. When rotating threaded rod 31 and making threaded rod 31 to the direction motion of keeping away from or being close to sleeve pipe 32, lifter 3 can accomplish and go up and down, so be convenient for adjust this portable height of putting up, and lifter 3's simple structure, the operation when needing lifter 3 to go up and down is also comparatively simple.

Referring to fig. 4, the three support legs 4 are respectively hinged with the outer side wall of the sleeve 32, a circular mounting plate 7 is fixedly connected with the outer side wall of the sleeve 32, and the outer side edge of the mounting plate 7 far away from the sleeve 32 is bent downwards to form a vertical part 71. The mounting plate 7 is located above the junction of the support leg 4 and the sleeve 32. Three joint groove 72 has been seted up to the lower surface of vertical portion 71, and when supporting leg 4 needed to be supported in ground, to keeping away from sleeve pipe 32 direction rotation supporting leg 4 until every supporting leg 4 and its nearly joint groove 72 joint of distance, supporting leg 4 can be comparatively stable support in ground this moment.

When this portable frame need be accomodate or transported, to the direction that is close to sleeve pipe 32 rotation supporting leg 4 makes supporting leg 4 contact sleeve pipe 32, this portable frame comparatively saves space this moment, is convenient for accomodate and transport.

Referring to fig. 4, the end of each support leg 4 far from the sleeve 32 gradually shrinks towards the direction far from the sleeve 32, so that when the portable stand is applied to the soil bottom surface, the support legs 4 can be inserted into the ground to make the portable stand stably supported on the ground.

The implementation principle of the fixed portable frame of spirit level convenient to leveling of this application embodiment is: when the fixing base 1 inclines due to the inclination of the ground, the abutting rods 53 on each fixing block 51 are loosened, the abutting rods 53 are separated from the guide rods 61, then the fixing base 1 can be adjusted to enable the fixing base 1 to tend to be horizontal, and finally the abutting rods 53 are screwed, so that each abutting rod 53 abuts against the guide rods 61.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
