Technical Field
[0001] This utility model relates to the field of outdoor drawing devices, and in particular to an outdoor drawing device. Background Technology
[0002] The outdoor drawing device is used by drafters to draw geological features outdoors. The device consists of a placement board and a connecting strap. When using the device, the drafter hangs the connecting strap around their neck and places the placement board horizontally in front of their chest, so that the connecting strap and placement board form a right-angled triangle with the drafter. The drafter places the drawing on the placement board and then picks up a drawing pen to begin drawing outdoors.
[0003] In their daily work, the inventors discovered that when using the outdoor drawing device, the connecting straps are quite long. To avoid affecting carrying, drawing workers usually wrap the connecting straps together and then tie them in knots to store them, which can make storing the connecting straps quite troublesome. Utility Model Content
[0004] The purpose of this invention is to solve the problem that in actual use, due to the long length of the connecting strap, drawing workers usually wrap the connecting strap together and then tie it in a knot to avoid affecting carrying, which may make the storage of the connecting strap quite troublesome. Therefore, this invention proposes an outdoor drawing device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an outdoor drawing device, comprising a placement plate, wherein a storage component and a connecting strap are provided at the upper end of the placement plate, and a placement component is provided at the left end of the placement plate. The storage component includes a storage groove formed at the upper end of the placement plate, a storage wheel is rotatably connected to the inner wall of the storage groove, the storage wheel is fixed to the connecting strap, the other end of the connecting strap is fixed to the placement plate, a connecting shaft is fixedly connected to the left end of the storage wheel, the connecting shaft passes through the placement plate, and a ratchet is fixedly connected to the left end of the connecting shaft.
[0006] The effect achieved by the above components is as follows: by setting up a storage component, when it is necessary to store the connecting strip, the ratchet is rotated, causing the storage wheel connected to the connecting shaft to rotate, so that the connecting strip is wound up to the surface of the storage wheel in the storage groove, thereby facilitating the storage of the connecting strip as much as possible.
[0007] Preferably, a torsion spring is fixedly connected to the right end of the ratchet, and the other end of the torsion spring is fixed to the placement plate.
[0008] The effect achieved by the above components is as follows: by setting a torsion spring, the worker pulls out the connecting belt on the storage wheel, causing the storage wheel to rotate, which causes the torsion spring to deform, loosens the connecting belt, and the torsion spring to return to its original position, thereby causing the storage wheel to rotate and wrap the connecting belt around the storage wheel, thus assisting in the storage of the connecting belt.
[0009] Preferably, a mounting cover is fixedly connected to the back of the placement plate, and a pawl is rotatably connected to one side of the inner wall of the mounting cover.
[0010] The effect achieved by the above components is as follows: by setting the mounting cover and pawl, the worker pulls out the connecting belt on the storage wheel, causing the storage wheel to rotate. Under the action of the pawl, the storage wheel cannot rotate under the reset of the torsion spring, thereby limiting the storage wheel.
[0011] Preferably, a first spring is fixedly connected to one side of the pawl, and the other end of the first spring is fixed to the mounting cover.
[0012] The effect achieved by the above components is that by setting the first spring, the pawl can better fit onto the ratchet.
[0013] Preferably, an operating rope is fixedly connected to the arc surface of the pawl, and the operating rope passes through the mounting cover.
[0014] The effect achieved by the above components is: pulling the operating rope on the mounting cover releases the pawl limit.
[0015] Preferably, the placement assembly includes a placement cylinder disposed at the left end of the placement plate, a cover disposed at the upper end of the placement cylinder, a U-shaped block fixedly connected to the arc surface of the placement cylinder, the U-shaped block sliding on the placement plate, and square insert rods slidably inserted into both sides of the placement plate, the square insert rods being inserted into the U-shaped block.
[0016] The above components achieve the following effects: when it is necessary to fix the placement tube, drag the placement tube so that the U-shaped block slides on the placement plate, allowing the square insert to be inserted into the U-shaped block for fixation. Open the cover on the placement tube to store drawing tools, and then close the cover.
[0017] Preferably, a second spring is fixedly connected between the two square inserts, and the second spring is located inside the placement plate.
[0018] The effect achieved by the above components is to reset the square insert by setting a second spring.
[0019] Preferably, a pull rope is fixedly connected between the two square inserts, and the pull rope passes through the placement plate.
[0020] The effect achieved by the above components is that pulling the pull rope causes the square insertion rod to retract into the placement plate.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] In this invention, by setting up a storage component, when the connecting strap needs to be stored, the ratchet is rotated, causing the storage wheel connected to the connecting shaft to rotate, so that the connecting strap is rolled up onto the surface of the storage wheel in the storage groove. This achieves the effect of conveniently storing the connecting strap as much as possible, solving the problem that because the connecting strap is long, in order to avoid affecting carrying, the drawing workers usually wrap the connecting strap together and then tie it in a knot to store it, which may make storing the connecting strap more troublesome.

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: an outdoor drawing device includes a placement plate 1, with a storage component 2 and a connecting strap 4 at the upper end of the placement plate 1, and a placement component 3 at the left end of the placement plate 1.
[0030] The following section will explain the specific settings and functions of storage component 2 and placement component 3.
[0031] Reference Figure 2 and Figure 3As shown in this embodiment: the storage component 2 includes a storage groove 21 formed on the upper end of the placement plate 1. A storage wheel 22 is rotatably connected to the inner wall of the storage groove 21. The storage wheel 22 is fixed to the connecting belt 4, and the other end of the connecting belt 4 is fixed to the placement plate 1. A connecting shaft 23 is fixedly connected to the left end of the storage wheel 22. The connecting shaft 23 passes through the placement plate 1, and a ratchet 24 is fixedly connected to the left end of the connecting shaft 23. By setting the storage component 2, when the connecting belt 4 needs to be stored, the ratchet 24 is rotated, causing the storage wheel 22 connected to the connecting shaft 23 to rotate, so that the connecting belt 4 is wound onto the surface of the storage wheel 22 in the storage groove 21, thereby facilitating the storage of the connecting belt 4 as much as possible. A torsion spring 25 is fixedly connected to the right end of the ratchet 24, and the other end of the torsion spring 25 is fixed to the placement plate 1. By setting the torsion spring 25, when the worker pulls out the connecting belt 4 from the storage wheel 22, the storage wheel 22 rotates, causing the torsion spring 25 to rotate. Deformation loosens the connecting strap 4, the torsion spring 25 resets, and the storage wheel 22 rotates, winding the connecting strap 4 onto the storage wheel 22, thus assisting in the storage of the connecting strap 4. A mounting cover 26 is fixedly connected to the back of the placement plate 1. A pawl 27 is rotatably connected to one side of the inner wall of the mounting cover 26. By setting the mounting cover 26 and the pawl 27, the worker pulls out the connecting strap 4 from the storage wheel 22, causing the storage wheel 22 to rotate. Under the action of the pawl 27, the storage wheel 22 cannot rotate under the reset of the torsion spring 25, thus limiting the storage wheel 22. A first spring 28 is fixedly connected to one side of the pawl 27, and the other end of the first spring 28 is fixed to the mounting cover 26. By setting the first spring 28, the pawl 27 is better fitted onto the ratchet 24. An operating rope 29 is fixedly connected to the arc surface of the pawl 27. The operating rope 29 passes through the mounting cover 26. Pulling the operating rope 29 on the mounting cover 26 releases the limitation of the pawl 27.
[0032] Reference Figure 4 and Figure 5 As shown in this embodiment: the placement component 3 includes a placement cylinder 31 located at the left end of the placement plate 1. A cover 32 is provided at the upper end of the placement cylinder 31. A U-shaped block 33 is fixedly connected to the arc surface of the placement cylinder 31. The U-shaped block 33 slides on the placement plate 1. Square rods 34 are slidably inserted on both sides of the placement plate 1. The square rods 34 are inserted into the U-shaped block 33. When it is necessary to fix the placement cylinder 31, drag the placement cylinder 31 so that the U-shaped block 33 slides on the placement plate 1, so that the square rods 34 are inserted into the U-shaped block 33 for fixation. Open the cover 32 on the placement cylinder 31 to store drawing tools, and then close the cover 32. A second spring 35 is fixedly connected between the two square rods 34. The second spring 35 is located inside the placement plate 1. By setting the second spring 35, the square rods 34 are reset. A pull rope 36 is fixedly connected between the two square rods 34. The pull rope 36 passes through the placement plate 1. Pulling the pull rope 36 causes the square rods 34 to retract into the placement plate 1.
[0033] Working principle:
[0034] When using the outdoor drawing device, the worker hangs the connecting strap 4 around their neck and places the placement plate 1 horizontally in front of their chest, forming a right-angled triangle with the worker and the connecting strap 4. The worker places the drawing on the placement plate 1 and then picks up a drawing pen to begin outdoor drawing. When it is necessary to store the connecting strap 4, the ratchet 24 is rotated, causing the storage wheel 22 connected to the connecting shaft 23 to rotate. This allows the connecting strap 4 to be wound onto the surface of the storage wheel 22 within the storage groove 21, facilitating the storage of the connecting strap 4. A torsion spring 25 is also used; when the worker pulls the connecting strap 4 off the storage wheel 22, the wheel rotates, causing the torsion spring 25 to deform, releasing the connecting strap 4. The torsion spring 25 then returns to its original position, allowing the storage wheel 22 to rotate again, winding the connecting strap 4 around itself, thus aiding in the storage of the connecting strap 4. With the mounting cover 26 and pawl 27 in place, the worker pulls out the connecting belt 4 on the storage wheel 22, causing the storage wheel 22 to rotate. Under the action of the pawl 27, the storage wheel 22 cannot rotate under the reset of the torsion spring 25, thus limiting the storage wheel 22. By setting the first spring 28, the pawl 27 is better attached to the ratchet 24. Pulling the operating rope 29 on the mounting cover 26 releases the limitation of the pawl 27. When it is necessary to fix the placement cylinder 31, drag the placement cylinder 31 so that the U-shaped block 33 slides on the placement plate 1, so that the square plug 34 is inserted into the U-shaped block 33 for fixation. Open the cover 32 on the placement cylinder 31 to store the drawing tools, and then close the cover 32. By setting the second spring 35, the square plug 34 is reset. Pulling the pull rope 36 causes the square plug 34 to retract into the placement plate 1.
