[0002] In construction, engineering surveying equipment includes GPS signal receivers, theodolites, total stations, gyroscopes and the data necessary for measurement. It is a general term for equipment used to measure one or several types of quantities. In telecommunications technology, it refers to equipment used to measure various electrical, magnetic, and optical parameters or generate test signals. Measuring equipment is the basis of technical, quality and economic work. Measuring equipment management is an important part of enterprise management and is of great significance to improving product quality, saving energy, reducing consumption, etc. It can directly or indirectly affect the product quality and economic benefits of the enterprise.

[0003] In the prior art, the inventors found that there are at least the following problems in the technology:

[0004] (1) The existing measuring instruments are generally equipped with a supporting tripod at the bottom when in use, but the existing supporting frame is not convenient to adjust the installation angle and length of the supporting frame when in use, which also causes poor stability of the device when used on an unstable ground;

[0005] (2) When the measuring instrument is testing, it will sample multiple groups of measuring points. Therefore, the device will be fixed at the same coordinate point and only rely on adjusting the measuring direction to change. Therefore, when changing the measuring point, the position of the entire device needs to be adjusted, which is very inconvenient. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a construction engineering measurement device, which has the advantages of conveniently adjusting the installation angle and length of the support frame and facilitating the adjustment of the measurement angle of the measuring instrument, thereby solving the problems raised in the background technology.

[0007] The utility model provides the following technical solution: a construction engineering measurement device, comprising a base, the upper surface of the base is fixedly connected to a cover box by bolts, the base and the interior of the cover box form a spherical cavity, and an inlaid universal ball is movably inlaid inside, the top of the inlaid universal ball is fixedly connected to a turntable seat, a measuring instrument is fixedly installed on the upper surface of the turntable seat, the bottom end of the inlaid universal ball is fixedly connected to a hand rod, the edges of the lower surface of the base are fixedly connected to hinged heads, a support arm is rotatably connected in the hinged head, a slide rod is slidably inserted at the bottom end of the support arm, and a pointed head is fixedly connected to the bottom end of the slide rod.

[0008] Preferably, the number of the hinged joints is three, and they are arranged in a circle about the lower surface of the base.

[0009] Preferably, the bottom end of the support arm is fixedly connected with a petal-shaped threaded barrel, the petal-shaped threaded barrel is slidably sleeved on the surface of the sliding rod, and a locking threaded barrel is threadedly sleeved on the surface of the petal-shaped threaded barrel.

[0010] Preferably, a sliding block is fixedly connected to the top of the sliding rod, a groove is provided on the side of the sliding block, an inner convex strip is fixedly connected to the inner wall of the supporting arm, and the inner convex strip is slidably engaged with the groove.

[0011] Preferably, a threaded rod is threadedly inserted into the side wall of the cover box, one end of the threaded rod is fixedly connected to a handle, and the other end of the threaded rod is fixedly connected to an abutment plate, and one side surface of the abutment plate is in contact with the surface of the internally embedded universal ball.

[0012] Preferably, a dustproof rubber sleeve is fixedly connected to the bottom end of the base, and the bottom end of the dustproof rubber sleeve is fixedly connected to the surface of the hand lever.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By providing a support arm, when placing the device, the support arm is rotated to unfold the three support arms separately to form a tripod to provide support for the device. At the same time, the bolts on the hinge joint can be rotated to fix the unfolded support arms, and the unfolding angle of the support arms can be adjusted. When the placement ground is not flat enough, the locking threaded cylinder can be manually loosened to allow the slide rod to slide at the bottom end of the support arm, so that the height of the pointed head can be adjusted separately, so that the bottom end of the pointed head can contact the ground to provide good support for the device, thereby ensuring that the device can be used normally in different terrains, greatly reducing the limitations of the device when used, and improving the accuracy of measurement.

[0015] 2. By providing an embedded universal ball, after the base and the cover box are fixedly connected by bolts, the embedded universal ball can be movably embedded in the cavity formed by them. After the device is placed stably, the hand lever can be held manually to drive the embedded universal ball to rotate, so as to adjust the inclination angle of the measuring instrument. After its position is confirmed, the handle can be turned manually to drive the threaded rod to move in the side wall of the cover box, so that the abutment plate moves accordingly, so that the inner wall of the abutment plate is closely fitted with the surface of the embedded universal ball, thereby increasing the friction between the embedded universal ball and the position of the embedded universal ball. At this time, the measuring instrument can be rotated to measure the target, which greatly improves the convenience of the surveyor in performing fixed-point multi-target measurement.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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] Reference Figure 1-4 A construction engineering measurement equipment comprises a base 1, the upper surface of the base 1 is fixedly connected with a cover box 2 by bolts, the base 1 and the interior of the cover box 2 form a spherical cavity, and an inner universal ball 3 is movably inlaid inside, the top of the inner universal ball 3 is fixedly connected with a turntable seat 4, a measuring instrument 5 is fixedly installed on the upper surface of the turntable seat 4, the bottom end of the inner universal ball 3 is fixedly connected with a hand lever 6, the edges of the lower surface of the base 1 are fixedly connected with hinged joints 11, a support arm 12 is rotatably connected in the hinged joint 11, a slide rod 13 is slidably inserted at the bottom end of the support arm 12, and a pointed head 14 is fixedly connected to the bottom end of the slide rod 13.

[0023] Among them, there are three hinged heads 11, which are arranged in a circle about the lower surface of the base 1. The support arms 12 are rotated to unfold the three support arms 12 respectively to form a tripod to provide support for the device. At the same time, the bolts on the hinged heads 11 can be rotated to fix the unfolded support arms 12, and the unfolding angle of the support arms 12 can be adjusted.

[0024] Among them, the bottom end of the support arm 12 is fixedly connected with a petal-shaped threaded tube 18, which is slidably sleeved on the surface of the slide rod 13. The surface of the petal-shaped threaded tube 18 is threadedly sleeved with a locking threaded tube 19. The locking threaded tube 19 is manually loosened to allow the slide rod 13 to slide on the bottom end of the support arm 12, so that the height of the pointed head 14 can be adjusted separately, so that the bottom end of the pointed head 14 can contact the ground to provide good support for the device.

[0025] Among them, the top of the slide rod 13 is fixedly connected with a slider 15, and a groove 17 is opened on the side of the slider 15. The inner wall of the support arm 12 is fixedly connected with an inner convex strip 16. The inner convex strip 16 is slidably engaged with the groove 17, which greatly improves the structural stability of the slide rod 13.

[0026] Among them, a threaded rod 8 is threadedly inserted into the side wall of the cover box 2, one end of the threaded rod 8 is fixedly connected to a handle 10, and the other end of the threaded rod 8 is fixedly connected to an abutment plate 9. One side surface of the abutment plate 9 fits with the surface of the embedded universal ball 3. When the handle 10 is turned by hand, the threaded rod 8 moves in the side wall of the cover box 2, so that the abutment plate 9 moves accordingly, so that the inner wall of the abutment plate 9 fits tightly with the surface of the embedded universal ball 3, thereby increasing the friction between the embedded universal ball 3 and the position of the embedded universal ball 3. At this time, the measuring instrument 5 can be rotated to measure the target.

[0027] The bottom end of the base 1 is fixedly connected with a dustproof rubber sleeve 7, and the bottom end of the dustproof rubber sleeve 7 is fixedly connected to the surface of the hand lever 6 to prevent the bottom of the embedded universal ball 3 from being stained with dust.

[0028] Working principle: when the device is in use, when placing the device, the support arm 12 is rotated, and the three support arms 12 are unfolded separately to form a tripod to provide support for the device. At the same time, the bolts on the hinge joint 11 can be rotated to fix the unfolded support arms 12, and the unfolding angle of the support arms 12 can be adjusted. When the ground on which the device is placed is not flat enough, the locking threaded cylinder 19 can be manually loosened to allow the slide rod 13 to slide at the bottom end of the support arm 12, so that the height of the pointed head 14 can be adjusted separately, so that the bottom end of the pointed head 14 can contact the ground to provide good support for the device, thereby ensuring that the device can be used normally in different terrains. In use, after the base 1 and the cover box 2 are fixedly connected by bolts, the embedded universal ball 3 can be movably embedded in the cavity formed by them. After the device is placed stably, the hand lever 6 can be held manually to drive the embedded universal ball 3 to rotate, so as to adjust the inclination angle of the measuring instrument 5. After its position is confirmed, the handle 10 can be turned manually to drive the threaded rod 8 to move in the side wall of the cover box 2, so that the abutment plate 9 moves accordingly, so that the inner wall of the abutment plate 9 is closely fitted with the surface of the embedded universal ball 3, thereby increasing the friction between the embedded universal ball 3 and the position of the embedded universal ball 3. At this time, the measuring instrument 5 can be rotated to measure the target.
