Description

Technical Field

[0001] The utility model relates to the field of water levels for civil engineering, and more specifically to a water level for civil engineering. Background Art

[0002] A level is an instrument used to measure the horizontality or verticality of the ground or a building; it usually consists of a telescope and an accurate horizontal or vertical bubble tube, and an adjustment tripod; its working principle is based on gravity, using the position of the bubble in the horizontal bubble tube to determine whether the measured surface is horizontal or vertical.

[0003] Chinese patent authorization announcement number: CN218411144U, provides a construction engineering level. This patent can perform horizontal adjustment and calibration when the level is installed through the limit adjustment mechanism, so as to ensure that the level is installed horizontally on an uneven mounting frame. Through the protection mechanism, the objective lens of the level can be covered when the level is idle, thereby providing a certain degree of protection for the objective lens of the level.

[0004] However, in the above patent, the level objective lens is protected only by a protective mechanism, and the level is a precision instrument. If it is hit or tipped over during use, it may be damaged, thereby affecting its measurement accuracy and stability. Utility Model Content

[0005] 1. Technical issues to be solved

In case of tipping, the traction rope is retracted, and the protective plate is lifted under the rebound force of the reset spring to wrap the level body, thereby effectively preventing the level body from being damaged and improving the safety and stability of the level body.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] The cam body is provided with a plurality of support legs, and the support legs are hinged on the support legs, and a groove is formed in the support legs, and a connecting plate is slidably connected in the groove. The upper end of the connecting plate is fixedly connected with a plurality of protective plates, and the protective plates all penetrate the support legs and extend to the outer end of the support legs. The lower end of the connecting plate is fixedly connected with a return spring, and the lower end of the connecting plate is fixedly connected with a traction rope, and the traction rope penetrates the support legs and the base plate and extends to the lower end of the base plate. The lower end of the traction rope is fixedly connected with a gravity iron ball, and the lower end of the base plate is fixedly connected with a magnetic suction cover, and the magnetic suction cover is located at the outer end of the traction rope. The protective plate is used to prevent the pre-dumping level body from being collided, and the gravity iron ball is used to maintain the stability of the level body. When the level body is dumped, the traction rope is retracted, and the protective plate is lifted under the rebound force of the return spring to wrap the level body, thereby effectively preventing the level body from being damaged and improving the safety and stability of the level body.

[0010] Furthermore, a damping shaft is fixedly installed between the base plate and the carrier plate, and the traction rope also passes through the damping shaft. Through the resistance of the damping shaft itself, when the angle of the level body is adjusted, its position can be slowly controlled and kept stable.

[0011] Furthermore, a buffer sleeve is fixedly connected to the outer end of the carrier plate, and the buffer sleeve can be used to buffer and reduce damage to the level instrument as a whole after it falls over under the protection of the buffer sleeve.

[0012] Furthermore, the elastic force of the return spring is smaller than the gravity of the gravity iron ball, and the gravity of the gravity iron ball can overcome the elastic force of the return spring to pull the multiple protective plates into the groove, so that the level body can be used.

[0013] Furthermore, a retractable groove is provided on the upper end of one of the protective plates, a reel is rotatably connected to the retractable groove, a dust-proof yarn is wrapped around the outer end of the reel, and a pull block is fixedly connected to the upper end of the dust-proof yarn. The dust-proof yarn is stretched by pulling the pull block to cover the upper end of the level body. When not in use, it can not only play a protective role, but also reduce dust adhesion.

[0014] Furthermore, a fixing buckle is fixedly connected to the side end of the pull block, and a slot matching the fixing buckle is provided on the upper end of the other protective plate opposite thereto. The fixing buckle is buckled into the slot to prevent the dustproof yarn from being automatically retracted into the storage slot.
