Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping tool boxes, in particular to a surveying and mapping tool box convenient for transportation. Background Technique

[0002] A surveying and mapping tool box refers to a collective container for tools and equipment used to measure and draw geospatial data. Common surveying and mapping tools include theodolites, levels, as well as pencils, rulers, set squares, etc. Using a surveying and mapping tool box to accommodate multiple different devices or tools facilitates the carrying by surveying and mapping staff.

[0003] Upon retrieval, a surveying and mapping tool box with the publication number CN218802192U, which relates to the technical field of surveying and mapping engineering, includes a tool box body, a steel plate, and a shoulder strap. A telescopic winding belt mechanism is fixedly connected to the outer bottom of the tool box body. The telescopic winding belt mechanism includes a nylon belt. One end of the nylon belt is fixedly installed with a belt tube, and the shaft part of the belt tube is rotatably connected to a belt bin. In this utility model, the tool box body is carried on the back by passing the arm through the shoulder strap. The knob is rotated clockwise, the belt tube winds and contracts the nylon belt, the pawl is stuck on the outside of the ratchet wheel, and the ratchet wheel is stuck from rotating counterclockwise, thereby restricting the belt tube. The loop formed by the shoulder strap and the nylon belt shrinks. When the length of the shoulder strap is short, the button is pressed inward, the pawl is disengaged from the ratchet wheel, the length of the nylon belt is extended, and after the button is released, the pawl re-sticks to the ratchet wheel and the length is fixed. By setting the telescopic winding belt mechanism, the tool box body can be carried on the back and the length of the shoulder strap can be adjusted at the same time, improving the comfort of carrying.

[0004] Based on the above patent, by setting the telescopic winding belt mechanism, the tool box body can be carried on the back and the length of the shoulder strap can be adjusted at the same time, improving the comfort of carrying. When the tool box body is carried on the back by passing the arm through the shoulder strap and the shoulder strap feels long, the knob is rotated clockwise. The knob drives the ratchet wheel and the belt tube to rotate clockwise. The belt tube winds and contracts the nylon belt. The pawl is stuck on the outside of the ratchet wheel, and the ratchet wheel is stuck from rotating counterclockwise, thereby restricting the belt tube. The loop formed by the shoulder strap and the nylon belt shrinks. When the length of the shoulder strap is short, the button is pressed inward. The button pushes the pawl to slide on the outside of the smooth column, and the pawl is disengaged from the ratchet wheel. At this time, the nylon belt is pulled to extend the length of the nylon belt. When the pawl slides, the first spring is compressed and deformed to generate elastic force. After the button is released, the elastic force pushes the pawl to re-stick to the ratchet wheel and the length is fixed, enabling the surveying and mapping worker to carry the tool box body more comfortably. However, the above technical means only aim to improve the comfort when the staff carry the tool box, and do not enable the staff to move the tool box conveniently and labor-savingly. Therefore, the effect on reducing the labor intensity of the staff is relatively small. Content of the Utility Model

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Referring to Figure 1-6 , an embodiment provided by the present utility model: A surveying and mapping toolbox convenient for transportation, including a toolbox main body 1, a base 2 fixedly connected to the bottom end of the toolbox main body 1, a cover plate 6 rotatably connected to the rear side of the top end of the toolbox main body 1, a buckle structure is arranged between the front end of the cover plate 6 and the front end of the toolbox main body 1 for limiting the cover plate 6 after it is covered, a chute cylinder 3 is fixedly connected to the right end of the toolbox main body 1, fixed plates 7 are fixedly connected to the lower sides of the front and rear ends of the inner wall of the base 2, pressure plates 8 are slidably connected to the inner walls of the through grooves in the middle of the left and right ends of the base 2, slide bolts 10 are slidably connected to the middle parts of the left and right ends of the inner wall of the base 2, and the opposite ends of the slide bolts 10 are fixedly connected to the middle parts of the opposite ends of the pressure plates 8.

[0028] Specifically, positioning rods 13 are fixedly connected to both the left and right sides of the top end of the fixed plate 7, and square plates 11 are fixedly connected to the opposite sides of the front and rear ends of the sliding bolts 10. A connecting frame 12 is slidably connected to the outer wall of the positioning rod 13. Grooves 20 are formed on the lower sides of the opposite ends of the connecting frames 12 on the left and right sides. The distances between the upper and lower ends of the square plates 11 are the same as the distances between the upper and lower ends of the inner walls of the grooves 20. Connecting discs 14 are fixedly connected to the bottom ends of the connecting frames 12, and rollers 15 are fixedly connected to the bottom ends of the connecting discs 14. Second springs 16 are fixedly connected to the outer diameters of the positioning rods 13 near the top ends of the connecting frames 12. The other ends of the second springs 16 are fixedly connected to the inner wall top ends of the base 2 near the outer diameters of the positioning rods 13. First springs 9 are fixedly connected to the front and rear sides of the opposite ends of the pressing plate 8. The other ends of the first springs 9 are fixedly connected to the inner wall of the base 2. Lay the toolbox main body 1 horizontally, and then press the two pressing plates 8 inward, so that the pressing plates 8 push the sliding bolts 10 to slide inward, and at the same time, the first springs 9 are compressed by the force. When the sliding bolts 10 are pushed, the square plates 11 on both sides will respectively disengage from the corresponding grooves 20, releasing the limit on the connecting frames 12. Then, under the elastic force of the second springs 16, the connecting frames 12 slide outward on the outer wall of the positioning rods 13 and drive the rollers 15 to extend out of the base 2. Then release the pressing plates 8, and under the elastic force of the first springs 9, the sliding bolts 10 drive the square plates 11 to reset. Then lift and place the toolbox main body 1 upright. At this time, the top of the connecting frame 12 is blocked by the reset square plates 11, preventing the rollers 15 from retracting into the base 2.

[0029] Specifically, a telescopic rod 4 is slidably connected to the inner wall of the top end of the chute cylinder 3. The sliding between the chute cylinder 3 and the telescopic rod 4 has a damping effect. Therefore, after the telescopic rod 4 is pulled up, it will not easily slide down, and the telescopic rod 4 also has a damping effect inside. A handle 5 is fixedly connected to the top end of the telescopic rod 4. Slide the telescopic rod 4 out of the chute cylinder 3 and then stretch the telescopic rod 4 to raise the height of the handle 5. The staff can hold the handle 5 and then push the toolbox main body 1, and the bottom rollers 15 roll, realizing the movement of the toolbox main body 1, thereby providing convenience and labor saving for the staff when transporting the toolbox main body 1. A storage bag 17 is detachably connected to the inner wall of the toolbox main body 1. Through the storage bag 17 nested inside the toolbox main body 1, when the tools are put into the toolbox main body 1, the stains on their surfaces will not adhere to the inner wall of the toolbox main body 1, effectively keeping the inside of the toolbox main body 1 clean. Compared with cleaning the inner wall of the toolbox main body 1, it is simpler and more convenient to clean the storage bag 17. Hook-and-loop fasteners with barbs 19 are fixedly connected to the upper parts of the four sides of the outer wall of the storage bag 17, and hook-and-loop fasteners 18 are fixedly connected to the upper parts of the four sides of the inner wall of the toolbox main body 1. Through the cooperation of the hook-and-loop fasteners 18 and the hook-and-loop fasteners with barbs 19, the limit of the storage bag 17 is realized. When cleaning the storage bag 17, just tear it between the hook-and-loop fasteners 18 and the hook-and-loop fasteners with barbs 19 to separate.

[0030] Working principle: First, lay the toolbox main body 1 horizontally, and then press the two side pressing plates 8 inward, so that the pressing plates 8 push the sliding bolts 10 to slide inward. At the same time, the first spring 9 is compressed by the force. When the sliding bolts 10 are pushed, the two square plates 11 will respectively disengage from the corresponding grooves 20, releasing the limit on the connecting frame 12. Then, under the elastic force of the second spring 16, the connecting frame 12 slides outward on the outer wall of the positioning rod 13 and drives the rollers 15 to extend out of the base 2. Then, release the pressing plate 8, and under the elastic force of the first spring 9, the sliding bolts 10 drive the square plates 11 to reset. Then, lift and place the toolbox main body 1 upright. At this time, the top of the connecting frame 12 is blocked by the reset square plates 11 to prevent the rollers 15 from being retracted into the base 2. Then, slide the telescopic rod 4 out of the chute cylinder 3 and stretch the telescopic rod 4 to raise the height of the handle 5. The staff can hold the handle 5 and then push the toolbox main body 1, and the bottom rollers 15 roll, realizing the movement of the toolbox main body 1, thereby providing convenience and labor saving for the staff when transporting the toolbox main body 1. Through the storage bag 17 nested inside the toolbox main body 1, when the tools are put into the toolbox main body 1, the stains on their surfaces will not adhere to the inner wall of the toolbox main body 1, effectively keeping the inside of the toolbox main body 1 clean. Compared with cleaning the inner wall of the toolbox main body 1, cleaning the storage bag 17 is simpler and more convenient. Through the cooperation of the fuzzy magic tape 18 and the hook magic tape 19, the limit of the storage bag 17 is realized. When cleaning the storage bag 17, just tear it between the fuzzy magic tape 18 and the hook magic tape 19 to separate them.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
