[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0027] See also Figures 1 to 6 As shown, an auxiliary drawing tool for foundation surveying and mapping includes a first pad 1, a fixing member 3 and two second pads 2, and the two second pads 2 are respectively hingedly arranged on both sides of the width direction of the first pad 1. In this embodiment, the hinge structure is a hinge structure in the prior art, which will not be described here. It should be noted that when the hinge structure is adopted, the hinge structure needs to be arranged on the back side of the first pad 1 and the second pad 2 to avoid affecting the drawing of the staff.

[0028] The fixing member 3 is used to keep the first pad 1 and the two second pads 2 in the unfolded state. In this embodiment, the fixing member 3 is slightly U-shaped and is arranged on one side of the length direction of the first pad 1, including a bottom plate 31 and side plates 32 fixed on both sides of the bottom plate 31 in the width direction, wherein the length of the fixing member 3 is greater than the width of the first pad 1, so that the bottom plate 31 and the two side plates 32 of the fixing member 3 are sleeved on one side of the length direction of the first pad 1 and the two second pads 2.

[0029] During implementation, the staff uses the hinge structure to keep the first pad 1 and the two second pads 2 in the unfolded state, and then takes the fixing member 3 and sets the fixing member 3 on one side of the length direction of the first pad 1 and the two second pads 2. It should be noted that since the length of the fixing member 3 is greater than the width of the first pad 1, the two ends of the fixing member 3 respectively exceed the joint of the first pad 1 and the second pad 2, and extend toward the corresponding second pad 2, so as to keep the first pad 1 and the two second pads 2 in the unfolded state. Preferably, there are two fixing members 3, and the two fixing members 3 are respectively clamped on both sides of the length direction of the first pad 1 to further limit the unfolded state of the first pad 1 and the two second pads 2.

[0030] A first fixing groove 5 is provided on one side of the first pad 1 in the length direction. Preferably, first fixing grooves 5 are provided on both sides of the first pad 1 in the length direction, and a clamping portion 4 is fixed on the inner side of the bottom plate 31 for clamping with the first fixing groove 5. That is, when the fixing member 3 is sleeved on one side of the first pad 1, the clamping portion 4 and the first fixing groove 5 are used to clamp the fixing member 3 and the first pad 1, thereby making the fixing member 3 and the first pad 1 more firmly fixed, and preventing the fixing member 3 from loosening during drawing.

[0031] In this embodiment, the first fixing groove 5 includes a positioning hole 51 provided on the outer side wall of the first pad 1 and a slot 52 connected to the inner side of the positioning hole 51. Figure 5 As shown, the first fixing groove 5 is an inverted T-shaped structure, and the inner diameter of the clamping groove 52 is larger than the inner diameter of the positioning hole 51. The clamping portion 4 includes two clamping plates 41 fixedly arranged on the bottom plate 31 at intervals, and the free ends of the two clamping plates 41 extend obliquely in a direction away from each other, and a clamping block 42 is convexly provided on one side of the two clamping plates 41 away from each other. When the clamping portion 4 cooperates with the first fixing groove 5, the two clamping blocks 42 are clamped on the side wall of the clamping groove 52 close to the positioning hole 51.

[0032] During implementation, the two card plates 41 and the two card blocks 42 of the clamping part 4 pass through the positioning hole 51 and move into the inside of the card slot 52, so that the card blocks 42 are clamped in the card slot 52. It should be noted that the two card plates 41 have a certain elasticity and can be made of plastic materials in the prior art, which is not limited here. When the card plate 41 is located inside the positioning hole 51, the two card plates 41 are squeezed by the inner side wall of the positioning hole 51, and the two card plates 41 are in a deformed state. When the card blocks 42 move to the inside of the card slot 52, they are no longer squeezed, so the two card plates 41 return to the initial state, and the card blocks 42 are clamped in the inside of the card slot 52. Preferably, the side of the two card blocks 42 away from each other is a beveled surface 421, and the beveled surface 421 extends obliquely from bottom to top in the direction away from the card plate 41, so as to facilitate the card blocks 42 to move into the inside of the card slot 52, that is, to facilitate the docking and clamping of the clamping part 4 and the first fixing groove 5.

[0033] In this embodiment, the fixing member 3 is further provided with a pull rod assembly 6 for releasing the engagement state between the engaging portion 4 and the first fixing groove 5. The pull rod assembly 6 comprises a rod body 61, a pull rope 62 and a pull ring 63. The rod body 61 is arranged on the outer side of the bottom plate 31. The bottom end of the rod body 61 slides through the bottom plate 31 to extend to the free ends of the two clamping plates 41 and is located between the two clamping plates 41. The bottom end of the rod body 61 is penetrated with a pull rope 62. The two ends of the pull rope 62 are respectively fixedly connected with the two clamping plates 41. The pull ring 63 is fixedly arranged at the top of the rod body 61. During implementation, the staff pulls the pull ring 63, and the pull ring 63 drives the rod body 61 to move away from the clamping plate 41. At this time, the pull rope 62 penetrated at the bottom of the rod body 61 is pulled, so that the free ends of the two clamping plates 41 move in a direction close to each other until the clamping block 42 is no longer engaged with the clamping groove 52, and then the staff can take out the fixing member 3. Preferably, a recess 311 for accommodating the pull ring 63 is formed on the outer side surface of the bottom plate 31 , so as to store the pull ring 63 .

[0034] Furthermore, the two second pads 2 are provided with second fixing grooves 7 on one side away from the first pad 1, wherein the structure of the second fixing grooves 7 is the same as that of the first fixing grooves 5, and both are adapted to the engaging portion 4. During implementation, when the staff has finished drawing and needs to fold and store the first pad 1 and the two second pads 2, the fixing member 3 connected to the first fixing groove 5 is first taken out, and then the fixing member 3 is connected to the second fixing groove 7, and then the second pads 2 are folded to facilitate the storage of the fixing member 3.

[0035] When the utility model is implemented, before drawing, the staff rotates the two second pads 2 through the hinge structure, and puts the first pad 1 and the two second pads 2 in the unfolded state, and then takes the fixing member 3, and puts the fixing member 3 on one side of the length direction of the first pad 1, and at the same time, the clamping part 4 is clamped with the first fixing groove 5. At this time, the second pad 2 is in a state that cannot be folded, so that the staff can lay the drawing on the auxiliary drawing tool. When the auxiliary drawing tool needs to be stored, the pull ring 63 is pulled, and the clamping block 42 is no longer clamped with the clamping groove 52 through the cooperation of the rod body 61 and the pull rope 62, so that the staff can take out the fixing member 3, and then clamp the fixing member 3 in the second fixing groove 7. At this time, the staff can rotate the second pad 2 for storage, so as to facilitate the carrying of the auxiliary drawing tool.

[0036] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of 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.
