[0033] The specific embodiments of the utility model will be described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but are not used to limit the scope of the utility model.
[0034] As Figs. 1 to 4 The anti-falling laser leveling instrument comprises a leveling instrument body 1, and a laser scanning head 2 is arranged at the upper end of the leveling instrument body 1. The difference lies in that an anti-falling top cover 3 is arranged at the upper end of the laser scanning head 2, so as to protect the laser scanning head 2 in case of accidental falling. Specifically, the anti-falling top cover 3 comprises a top cover body 4 connected with the laser scanning head 2, and an anti-falling protection frame 5 is arranged outside the top cover body 4. In order to realize effective combination, the anti-falling protection frame 5 and the top cover body 4 are combined by injection molding. At the same time, in order to realize effective buffering effect and absorb external stress impact during falling, a buffer cavity (not shown in the figure) is arranged inside the anti-falling protection frame 5, and a buffer lining (not shown in the figure) is filled in the buffer cavity. In this way, the stress is absorbed through the deformation of the buffer lining.
[0035] In combination with a preferred embodiment of the utility model, a plurality of positioning holes 6 are distributed on the top cover body 4, and positioning screws are preset in the positioning holes 6. In this way, the anti-falling top cover 3 is installed on the flatness detector body 1 through screw connection. Meanwhile, the edges of the top cover body 4 are distributed with extension connecting edges, and the extension connecting edges are connected with the anti-falling protection frame 5. Thus, the extension connecting edges can fill the connecting tolerance between the top cover body 4 and the anti-falling protection frame 5, so that the integrated integrity after injection molding can be satisfied, and the connecting sand hole will not appear. In addition, a plurality of reinforcing ribs 7 are distributed between the top cover body 4 and the extension connecting edge. In this way, when directly impacted from the top, the edge cracking can be avoided. Furthermore, a guide label 8 is arranged on the top cover body 4. Thus, during subsequent installation and injection molding, the staff can quickly identify and complete the correct connection.
[0036] Further, the top end of the top cover body 4 is distributed with a recess structure, and a stress release hole 9 is distributed at the center position of the recess structure. In this way, when stress impact is received, the stress can be transmitted to the stress release hole 9 through the recess structure. Then, the impact stress is dissipated through the deformation of the stress release hole 9, so that the stress is not concentrated at a certain point of the top cover body 4, and the cracking is avoided.
[0037] In combination with the actual implementation, the anti-falling protection frame 5 includes a frame body, the center of the frame body is provided with an embedding groove 10, and the top cover body 4 is embedded in the embedding groove 10. In this way, the pre-positioning before injection molding is satisfied. Meanwhile, the corners of the frame body are provided with buffer blocks 11. When accidental falling occurs, the buffer blocks 11 are preferentially contacted with the falling surface, so that the stress absorption buffer is realized. In order to avoid the cracking of the middle section, the edge of the frame body is provided with a reinforcing block 12, and the cross section of the reinforcing block 12 is a triangular structure. In this way, the appropriate edge reinforcement can be realized. In addition, the buffer block 11 is a conical protrusion. Thus, the uniform stress diffusion can be realized through the shape of the buffer block 11, so that the stress is not concentrated at some points. Furthermore, a plurality of deformation grooves 13 are distributed on the buffer block 11. In this way, when impact occurs, the stress impact received by the buffer block 11 can be reduced through the deformation of the deformation groove 13, so that the service life is improved.
[0038] Further, the buffer lining is a swelling agent lining or a foamed material lining. In this way, when stress impact is received, the anti-falling protection frame 5 can realize moderate deformation as a whole, so that the anti-falling effect is improved.
[0039] During manufacturing, the anti-falling protection frame 5 adopts a rubber coating design, and the buffer lining is filled in the buffer cavity. After injection molding is completed, the anti-falling protection frame 5 and the anti-falling top cover 3 can be covered by rubber coating, and the positioning holes 6 are separately processed. In this way, the integrated structure is better.
[0040] Meanwhile, the top cover body 4 can be processed by ABS material or nylon material. The encapsulating material is selected from TPE material or TPU material, and has better ductility and elasticity. Moreover, after the encapsulation is completed, the buffer cavity is filled with a swelling agent or foaming material. In this way, the effect of thickening filling can be achieved, and the encapsulation surface will not appear to be shrunk or scratched, and has better elastic buffering effect.
[0041] It can be seen from the above description and the drawings that the present application has the following advantages:
[0042] 1. The top cover body can be stably combined with the body of the leveling instrument, improving the convenience of assembly.
[0043] 2. The top cover body has a stress release hole, which can absorb certain stress impact through the deformation of the stress release hole.
[0044] 3. The anti-falling protection frame is provided with a buffer lining, which can realize flexible contact with hard objects such as the ground, and reduce the impact of knocking.
[0045] 4. The buffer block is provided, which can better cope with the impact caused by falling and improve the anti-falling ability.
[0046] 5. The encapsulation design can be adopted, and the injection molding is combined to make the entire anti-falling top cover have better integrity.
[0047] In addition, the indication of the direction or position relationship described in the present application is based on the direction or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or structure must have a specific direction or be operated in a specific direction, so it cannot be understood as a limitation of the present application.
[0048] The above is only the preferred embodiment of the present application, and is not used to limit the present application. It should be pointed out that for ordinary skilled persons in the technical field, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be regarded as the protection range of the present application.
