Description

Technical Field

[0001] The utility model relates to the technical field of protective covers of laser plumb line instruments, in particular to a protective cover of laser plumb line instruments. Background Art

[0002] The laser plumb line is an optical instrument that uses the gravity line as a reference to give a plumb line. It can be used to measure small horizontal deviations relative to the plumb line, transfer the point position of the plumb line, measure the vertical profile of an object, and transfer the vertical direction.

[0003] Laser plumb lines are mainly used in the construction of high-rise buildings, high towers, chimneys, and towers, the installation of launch traps, racks, and large cylindrical mechanical equipment, the horizontal displacement measurement of dams, engineering supervision, and deformation observation. This means that some of its usage occasions are outdoors or in places with complex environments. In this case, not only will external factors such as rain and dust cause the laser plumb line to be damaged by the external environment, but falling objects and water from high altitudes will also threaten the safety of its use. Therefore, the direct exposed use of the laser plumb line will not only be easily affected by the external environment, but may also pose a safety hazard.

[0004] After searching, the Chinese utility model patent with the announcement number CN219347762U discloses a protective cover for a laser plumb line, including an upper mounting plate, a lower mounting plate, a plurality of detachable connecting parts and a glass plate; a plurality of the detachable connecting parts are arranged circumferentially between the upper mounting plate and the lower mounting plate, and the upper mounting plate, the lower mounting plate and the detachable connecting parts constitute an integral structure; a plurality of the detachable connecting parts form a hollow area between the upper mounting plate and the lower mounting plate; the glass plate is detachably connected to the upper end surface of the upper mounting plate. This application provides a protective effect for the laser plumb line by arranging an upper mounting plate and a glass plate on the top of the laser plumb line, but the protection direction of the device is single, so it cannot effectively resist the damage of external factors to the laser plumb line in a complex use environment, and cannot provide sufficient protection for it.

[0025] Example 1

[0026] See attached Figure 1-2 The present application provides a protective cover for a laser vertical leveler, including a canopy 1 and a curtain 2. The canopy 1 is fixedly connected to the top of the curtain 2 to provide more all-round protection for the laser vertical leveler, thereby reducing the degree of damage to it by the external environment and ensuring its safety in use. The canopy 1 and the curtain 2 are both made of transparent plastic soft cloth, so it is convenient to observe the status of the laser vertical leveler itself during use, and it is convenient to store the canopy 1 and the curtain 2. The canopy 1 is used for top protection of the laser vertical leveler. A sleeve 7 is provided on the top of the canopy 1, and the canopy 1 is installed on the laser vertical leveler through the sleeve 7. By sleeve 7 on the objective lens of the laser vertical leveler, the installation of the device can be achieved, thereby ensuring the convenience of loading and unloading the device. 1 comprises a tarpaulin 102 and a plurality of frames 101. The tarpaulin 102 is unfolded and folded through the frames 101. When all the frames 101 are unfolded, the tarpaulin 102 will unfold accordingly, and vice versa, the tarpaulin 102 can be folded, and the folded tarpaulin 102 can reduce the volume for easy carrying and storage. A crease can be provided on the tarpaulin 102, so that it can be folded from the crease each time it is folded, so as to help ensure the flatness of its surface. The curtain 2 is used for the outer side protection of the laser vertical collimator. A fixing sleeve 3 is provided on one side of the curtain 2. The fixing sleeve 3 is used to adapt to the eyepiece of the laser vertical collimator, that is, the eyepiece of the laser vertical collimator can be placed at the fixing sleeve 3 for fixing, so as to ensure that the normal observation effect of the laser vertical collimator is not affected when it is used.

[0027] Preferably, the sleeve 7 is sleeved on the outside of the objective lens of the laser plumb line, and a number of spring sheets 701 are equidistantly fixedly connected to the inner side of the sleeve 7, and a gasket 702 is fixedly connected to one side of the spring sheet 701. Under the elastic force of the spring sheet 701, it can be ensured that the gasket 702 will be close to the objective lens of the laser plumb line, so the sleeve 7 can be fixed by this clamping method. The material of the gasket 702 is latex, and the gasket 702 made of latex material is elastic, so it can play a cushioning role for the outer wall of the objective lens, avoiding the elastic force of the spring sheet 701 from leaving indentations on the outer wall of the objective lens, and the top end of the sleeve 7 is sleeved with a cover shell 6.

[0028] Preferably, several skeletons 101 are equidistantly connected to the outside of the sleeve 7, and the skeleton 101 is composed of an outer shell of plastic material and an inner core of a spring steel wire bundle. The skeleton 101 made of the spring steel wire bundle is elastic, so the entire canopy 1 can be elastic, so as to better cope with the threat of falling objects that may occur in complex environments. The tarpaulin 102 is fixedly connected to the top of the skeleton 101, and the surrounding curtain 2 is fixedly connected to the outside of the bottom end of the tarpaulin 102 by Velcro. The surrounding curtain 2 and the canopy 1 are connected by Velcro, so that the two can be detachably connected. Therefore, after long-term use, the two can be disassembled and cleaned separately. In addition, when installing the two, they can also be installed in the order of canopy 1 first and curtain 2 later, so as to ensure the convenience of installation of the device.

[0029] Preferably, a circular opening is provided on one side of the curtain 2, and the fixing sleeve 3 is fixedly connected to the curtain 2 at the circular opening. A plurality of limit blocks 301 are fixedly connected at equal distances on one side of the interior of the fixing sleeve 3. The material of the limit blocks 301 is rubber. The limit blocks 301 can replace the inner wall of the fixing sleeve 3 to contact the eyepiece of the laser plumb line. Therefore, it can not only clamp and limit the eyepiece through its own softness, but also ensure the stability between the fixing sleeve 3 and the eyepiece through its own friction force. A limit sleeve 401 is provided on the other side of the interior of the fixing sleeve 3, and a cover plate 4 is fixedly connected to one side of the limit sleeve 401.

[0030] Preferably, the materials of the cover plate 4 and the cover shell 6 are both PMMA (acrylic resin) plastic, and the colors of the cover plate 4 and the cover shell 6 are both transparent. The cover plate 4 and the cover shell 6 are respectively used for targeted protection of the eyepiece and the objective lens, and the transparent colors of the two can avoid blocking the laser and the observation cross mark. However, even so, the cover plate 4 and the cover shell 6 should be removed when debugging the laser plumb line to ensure that the laser will not be disturbed in any way. After the debugging is completed, the cover plate 4 and the cover shell 6 are covered to provide sufficient protection. A connecting rope 5 is fixedly connected between the cover plate 4 and the curtain 2 and between the cover shell 6 and the sleeve 7. Since the cover plate 4 and the cover shell 6 are temporarily opened, the connecting rope 5 can be used to avoid the loss of the two, and it can also avoid the trouble of properly storing the two after removing them.

[0031] Preferably, a threaded groove is formed on the outside of the sleeve 7 at the bottom end of the frame 101, and a threaded ring 8 is threadedly connected to the sleeve 7 at the threaded groove. The threaded ring 8 is used to support the frame 101 and bind the tarpaulin 102. When the canopy 1 is in an open state, the threaded ring 8 can support the frame 101 at the bottom, thereby maintaining the expanded state of the frame 101. When the canopy 1 is in a closed state, the threaded ring 8 can be sleeved on the outside of the tarpaulin 102 to bind it, thereby facilitating the storage and carrying of the canopy 1.

[0032] Working principle: After setting up and debugging the laser vertical leveler, the canopy 1 can be unfolded, and then the threaded ring 8 can be installed at the outer bottom end of the sleeve 7. At this time, the threaded ring 8 can support all the frames 101, thereby maintaining the tarpaulin 102 in an unfolded state;

[0033] Then, the sleeve 7 can be placed on the outside of the objective lens of the laser plumb line. At this time, the spring sheet 701 can allow the gasket 702 to clamp the objective lens through its own elastic force, so that the canopy 1 is installed on the top of the laser plumb line. Then, the curtain 2 can be installed on the outside of the bottom end of the canopy 1 using Velcro.

[0034] In this case, the canopy 1 and the curtain 2 can provide protection for the top and outer sides of the laser plumb line respectively; when the laser plumb line needs to be further debugged or other operations are performed on it, the cover shell 6 and the cover plate 4 can be removed respectively, and then the hand can be put into the curtain 2 to operate the knob. After the debugging is completed, the cover shell 6 and the cover plate 4 can be respectively covered on the sleeve 7 and the fixing sleeve 3 to protect the objective lens and the eyepiece;

[0035] After the use of the laser plumb line instrument, the curtain 2 can be removed from the canopy 1 first, and then the canopy 1 can be removed from the laser plumb line instrument. The threaded ring 8 can then be twisted to remove it from the fixing sleeve 3, and the frame 101 can be moved to deflect it downward to fold the canopy 1. After that, the threaded ring 8 can be put on the outside of the canopy 1, so that the threaded ring 8 can be used to maintain the folded state of the canopy 1, thereby facilitating its storage.

[0036] Example 2

[0037] See attached Figure 3 The present application provides a protective cover for a laser plumb line instrument. Compared with Example 1, in order to facilitate further debugging or operation of the laser plumb line instrument, a plurality of slits 201 are opened on the outer side of the curtain 2. The positions of the slits 201 correspond to the positions of the operating knobs on the laser plumb line instrument. The slits 201 can divide the complete curtain 2 into a plurality of curtain bodies. In this case, if it is necessary to operate the knob on the laser plumb line instrument, it is only necessary to lift up the curtain body at the corresponding position. A plurality of counterweights 202 are equidistantly fixedly connected to the bottom end of the curtain 2. The counterweights 202 can maintain the curtain body in a vertically downward flat state through their own gravity, thereby preventing the curtain body from being lifted up by the blowing of external airflow and causing its protective effect to decrease.

[0038] Working principle: After the device is installed, when the laser plumb line needs to be further debugged or operated, the curtain 2 can be lifted from the slit 201. At this time, the operating knob of the laser plumb line will be exposed, making it convenient for further debugging or operation; in addition, under normal circumstances, the counterweight block 202 will maintain the curtain 2 in a vertically downward and flat state through its own gravity, thereby ensuring the protective effect provided by the curtain 2 for the laser plumb line.

[0039] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
