Description

Technical Field

[0001] The utility model relates to the technical field of laser levels, in particular to a laser level for construction. Background Art

[0002] Laser levels are a common tool for measuring angles. In the machinery and construction industries, they are used to measure tilt angles relative to the horizontal, flatness and straightness, and the horizontal and vertical positions of equipment installations. Especially for verticality measurements, the magnetic function allows high-strength levels to attach to vertical work surfaces, eliminating the need for manual support, reducing labor intensity and improving measurement accuracy.

[0003] When the current laser level is used, a line of light with uniform brightness is formed after passing through the light emitting lamp to assist the operator. However, the current light emitting lamps are all protected by a rectangular shell on their outer wall. Due to the rectangular frame, breakpoints may appear when used in special positions. Figure 1 As shown, it is not conducive to full use. In addition, it is extremely inconvenient to disassemble the body when replacing the protective cover. Therefore, we propose a construction laser level to solve the above problems. Utility Model Content

[0007] Preferably, the cylindrical protective tube is made of one of transparent plastic material and transparent glass material.

[0008] Preferably, a protective frame is provided around the luminous lamp.

[0009] Preferably, external threads are provided at equal intervals around the lower end of the cylindrical protection tube, and the lower end of the cylindrical protection tube is screwed onto the side wall of the level body through the external threads.

[0011] Preferably, the upper ends of the two arc-shaped slots are provided with threaded through holes, the clamping block is provided with a limiting hole, and the stud passes through the threaded through holes and extends into the limiting hole.

[0012] In the present invention, the previous rectangular protective cover is replaced with a cylindrical protective tube, which greatly improves the brightness of the laser lines emitted by the light-emitting lamp. In addition, there are no breakpoints for special angles, thereby ensuring use. When the damaged protective tube needs to be replaced, the cylindrical protective tube can be rotated to unscrew it, and then a new protective tube can be replaced and screwed on the thread. When firm fixation is required, the protective tube is replaced with a tube body with a card block structure, the card block is placed into the arc-shaped card slot through the notch, and then the tube body is rotated, and then two of the card blocks are firmly fixed with studs to ensure the strength and stability of the installation.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0023] Reference Figure 2-4 A construction laser level includes a level body 1, with light-emitting lamps 4 installed on the upper end and one side of the level body 1. A cylindrical protective tube 2 is provided on the outer side of the light-emitting lamp 4, and a protective cover 3 is fixed to one end of the cylindrical protective tube 2. The cylindrical protection fully realizes the frameless processing and solves the problem of breakpoints after the laser is irradiated.

[0024] The cylindrical protective tube 2 is made of a transparent plastic material or a transparent glass material, which fully meets the lighting requirements. The corresponding material is selected according to the usage, and no refraction occurs under the premise of improving light transmittance;

[0025] External threads 5 are provided at equal intervals around the lower end of the cylindrical protective tube 2. The lower end of the cylindrical protective tube 2 is screwed onto the side wall of the level body 1 through the external threads 5. Through the threaded connection, quick installation and disassembly can be achieved, which can facilitate operators to quickly disassemble and install and reduce labor costs. Example

[0026] Reference Figure 5-7 , the difference between this embodiment 2 and embodiment 1 is that this embodiment 2 also includes four blocks 6 fixed at equal intervals around the lower end of the cylindrical protective tube 2, and a mounting opening 8 is provided at the upper end of the level body 1. Four arc-shaped slots 12 are provided at equal intervals on the side wall around the mounting opening 8, and a notch 11 is provided at the upper end of the arc-shaped slot 12. The four blocks 6 respectively penetrate the four notches 11 and extend into the arc-shaped slot 12, two of which are connected to the arc-shaped slot 12 through studs 9, and threaded through holes 10 are provided at the upper ends of the two arc-shaped slots 12. A limiting hole 7 is provided on the block 6, and the stud 9 penetrates the threaded through hole 10 and extends into the limiting hole 7. Through the combination of the block 6 and the stud 9, a stable and firm installation can be achieved, ensuring stable durability.

[0027] In the present invention, the previous rectangular protective cover is replaced with a cylindrical protective tube 2, which greatly improves the brightness of the laser lines emitted by the light-emitting lamp 4. In addition, there are no breakpoints for special angles, thereby ensuring usage. When the damaged protective tube needs to be replaced, the cylindrical protective tube 2 can be rotated to unscrew it, and then a new protective tube can be replaced and screwed on. When firm fixation is required, the protective tube is replaced with a tube body with a card block 6 structure, and the card block 6 is placed into the arc-shaped card groove 12 through the notch 11, and then the tube body is rotated, and then two of the card blocks 6 are firmly fixed using studs 9 to ensure the strength and stability of the installation.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
