Description

Technical Field

[0001] The utility model belongs to the technical field of tool boxes, in particular to a tool box body for engineering measurement. Background Art

[0002] Engineering surveying refers to the process of measuring, recording and analyzing the ground, buildings, structures, land, etc. using surveying technology and instruments during the construction process to obtain various geographic and spatial data, and then process, analyze and apply these data. Engineering surveying is an important part of engineering construction. It provides accurate geographic and spatial information for engineering design, planning, construction and management, and ensures the quality and safety of engineering projects. Engineering surveying requires many tools and instruments, and workers usually use tool boxes to carry tools.

[0003] When measuring on site, workers need to record the measurement data and draw a simple diagram based on the site to facilitate later understanding. Due to the limitation of the measurement site, workers usually record and draw on the top of a relatively flat toolbox. However, since the toolbox is relatively short, workers need to squat and bend over to record. If workers maintain this posture for a long time, their backs will be very sore.

DETAILED DESCRIPTION

[0029] 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. Example

[0030] A tool box for engineering measurement, such as Figure 1As shown, it includes a box body 2, a box cover 1 and a placement portion 3; wherein a tool storage space is provided in the box body 2, the box cover 1 is hinged to the box body 2, and the placement portion 3 is connected to the bottom of the box body 2; the tool storage space is used to store measuring tools and testing instruments. The box cover 1 is hinged to the box body 2 to facilitate opening the box body 2.

[0031] like Figures 2 to 3 As shown, the placement portion 3 includes a bottom plate 4, a support leg 5, a connecting seat 10, a rotating shaft 8, a limiting head 16 and a limiting rod 14;

[0032] The bottom plate 4 and the connecting seat 10 are both fixedly connected to the bottom of the box body 2, the rotating shaft 8 is rotatably connected to the connecting seat 10, the supporting leg 5 is fixedly connected to the rotating shaft 8 and the supporting leg 5 is arranged vertically to the rotating shaft 8, one side of the rotating shaft 8 penetrates the connecting seat 10 and is fixedly connected to the limiting head 16, one side of the limiting head 16 is provided with a square limiting hole 15, and the limiting rod 14 is movably connected to the bottom plate 4 and can be inserted into the limiting hole 15 to fix the angular position of the limiting head 16. In a feasible solution, the limiting rod 14 is fixedly connected to a limiting sleeve matching the shape of the limiting rod 14, and the limiting rod 14 is movably inserted in the limiting sleeve. Fixing the angular position of the limiting head 16 is to fix the angular position of the rotating shaft 8 and the supporting leg 5. It should also be noted that the width of the bottom plate 4 should be greater than the height of the connecting seat 10, that is, when the tool box body is placed on the ground, only the bottom plate 4 is in contact with the ground, thereby protecting other structures in the placement part 3 and preventing other structures in the placement part 3 from being crushed.

[0033] Specifically, when in use, after arriving at the site, first open the box cover 1, take out the measuring tools and testing instruments in the box body 2, and close the box cover 1. Pull out the limit rod 14 from the limit hole 15, at this time, the limit head 16 will no longer be restricted and can rotate. Rotate the support leg 5 90 degrees so that the support leg 5 is perpendicular to the bottom surface of the box body 2. Since the limit hole 15 is a square structure, the limit rod 14 can just be inserted into the limit hole 15 and fix the angle position of the limit head 16, thereby fixing the angle position of the rotating shaft 8 and the support leg 5. In this way, all the support legs 5 in the placement part 3 are opened. The support leg 5 can raise the height of the box body 2 and the box cover 1, so as to facilitate the staff to record data and draw manuscripts on the box cover 1. Since the height of the box body 2 and the box cover 1 is raised, the staff does not need to bend down to work when using it, making the operation more convenient. In addition, with this design, after the on-site measurement and recording is completed, the tool box can be quickly restored, which is convenient for carrying the tool box.

[0034] In a preferred embodiment, Figure 1As shown, both the box body 2 and the box cover 1 adopt a sandwich structure, which effectively improves the protective performance of the box body 2 and the box cover 1. This structure can withstand greater external forces and effectively protect the internal testing tools and testing instruments. At the same time, the selection of the sandwich material can also be adjusted according to the characteristics required by the actual situation, such as moisture-proof and fire-proof, to ensure the safety of the measuring tools and testing instruments during transportation and storage.

[0035] In a preferred embodiment, Figure 5 As shown, a contact plate 22 made of rubber material is provided at the bottom of the bottom plate 4. The contact plate 22 made of rubber material enables the bottom plate 4 to contact the ground more stably, ensuring the stability of the tool box body when it is placed on the ground.

[0036] In a preferred embodiment, Figure 1-4 As shown, the bottom of the box body 2 is located in the support legs 5 on the left and right sides, and the support legs 5 on the same side are connected together by a connecting rod 9. The support legs 5 on the same side are connected together by the connecting rod 9 to ensure the stability of the support legs 5. After the support legs 5 on the same side are connected by the connecting rod 9, a frame structure is formed, so that the support legs 5 are more stable and less likely to shake.

[0037] In a preferred embodiment, Figure 4 As shown, the bottom of the support leg 5 is connected with a foot 20. The foot 20 is used to increase the contact area between the support leg 5 and the ground, so that the support leg 5 can be more stable.

[0038] In a preferred embodiment, Figure 4As shown, the support leg 5 includes an outer cylinder 501 and an inner rod 502, one side of the inner rod 502 is movably arranged in the outer cylinder 501, a plurality of bolt holes are evenly spaced along the axial direction on the inner rod 502, and a connecting groove 18 is arranged on one side of the outer cylinder 501 near the bottom; the outer cylinder 501 and the inner rod 502 are connected by a locking bolt 17, and the locking bolt 17 passes through the connecting groove 18 and the bolt hole in sequence and fixes the relative position of the outer cylinder 501 and the inner rod 502. Specifically, the connecting groove 18 is a waist-shaped groove. It should be noted here that the interval between the bolt holes on the inner rod 502 should ensure that there is always a bolt hole that can cooperate with the connecting groove 18. For example, if the length of the connecting groove 18 is 10 cm, the interval between adjacent bolt holes should be less than 10 cm. The support leg 5 is designed as an outer cylinder 501 and an inner rod 502 in order to enable the support leg 5 to be retractable, so as to facilitate the storage of the support leg 5 while increasing the length of the support leg 5. When the length of the support leg 5 needs to be adjusted, the locking bolt 17 is removed, and the inner rod 502 is pulled out of the outer cylinder 501 or inserted into the outer cylinder 501. After the overall length of the support leg 5 is determined, the locking bolt 17 is passed through the connection slot 18 and the bolt hole in sequence and locked, thereby fixing the length of the support leg 5. In addition, the box can be stably placed on an uneven ground by adjusting the height of each support leg 5, which is convenient for the staff to record data or draw manuscripts.

[0039] In a preferred embodiment, Figure 4 As shown, a circle of contact portion 19 is fixedly connected to the edge of the connecting groove 18 on the outer cylinder 501, and the contact portion 19 can be made of wood material, and the contact portion 19 is used to directly contact the locking bolt 17. The locking bolt 17 needs to be tightened to lock the outer cylinder 501 and the inner rod 502, so the contact portion 19 is used as an intermediate component to prevent the outer cylinder 501 from being deformed. The deformation of the outer cylinder 501 will cause the inner rod 502 to be unable to move normally.

[0040] In a preferred embodiment, Figure 5 As shown, an axial limit portion 11 is fixedly connected to the rotating shaft 8 at a position close to the connecting seat 10, and the axial limit portion 11 is used to limit the position of the rotating shaft 8 in the axial direction. By providing the axial limit portion 11, the rotating shaft 8 can be effectively prevented from moving in its axial direction, thereby ensuring the stability of the supporting leg 5.

[0041] In a preferred embodiment, Figures 2 to 3As shown, a square through hole 21 is provided on the base, and the limit rod 14 is movably arranged in the through hole 21, and a stopper 6 is fixedly connected to one end of the limit rod 14 away from the limit head 16; pulling holes are provided on both sides of the through hole 21 on the base, and both sides of the stopper 6 are fixedly connected to the pull rod 13, and the pull rod 13 penetrates the pulling hole; a tension spring 12 is connected to the pull rod 13, and the other end of the tension spring 12 is connected to the connecting seat 10. Further optimized, a pull ring 7 is fixedly connected to the stopper 6. Specifically, when the support leg 5 needs to be released during use, the stopper 6 is pulled through the pull ring 7, and the stopper 6 drives the limit rod 14 to leave the limit hole 15. After the position of the support leg 5 is adjusted, the pull ring 7 is released, the tension spring 12 is reset and drives the pull rod 13 to reset, the pull rod 13 drives the stopper 6 to reset, and the stopper 6 drives the limit rod 14 to reset. This design can facilitate the control of the limit rod 14, thereby realizing rapid adjustment of the angle position of the support leg 5, and facilitating rapid placement of the tool box.
