Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a plumb bob device for preventing knotting in building construction. Background Technology

[0002] A plumb bob, also called a vertical plumb bob, is a conical object made of metal (iron, steel, copper, etc.) primarily used for measuring the verticality of objects, and is commonly seen in construction processes. The method of using a suspended plumb bob involves suspending a relatively heavy, specially made plumb bob at a predetermined intersection point of axes, directly lowering it to each construction floor to measure the axis.

[0003] Current plumb bob devices are equipped with a fixing mechanism to secure the plumb bob to a designated position before releasing the plumb bob for measurement. However, once the plumb bob is fixed by the fixing mechanism, its position is not easy to fine-tune. If there is a certain deviation in the determined position, the plumb bob needs to be disassembled and repositioned, which is quite troublesome. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given that the existing plumb bob devices, once fixed by a fixing mechanism, are not convenient to fine-tune in position, and if there is a certain deviation in the determined position, the plumb bob device needs to be disassembled and repositioned, which is quite troublesome.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A plumb bob device for preventing knotting in construction projects, characterized in that it comprises:

[0008] The winding mechanism includes a winding shell, a connecting line disposed inside the winding shell, and a hammer fixed to the bottom of the connecting line;

[0009] The adjustment mechanism includes a support plate slidably mounted on the top of the winding shell, an adjustment groove formed on the surface of the support plate, a limiting groove formed on the side of the support plate, an adjustment slider disposed between the winding shell and the support plate, and a limiting screw threaded to the side of the adjustment slider.

[0010] The fixing mechanism includes a fixing plate fixed to the end of the support plate;

[0011] The limiting mechanism includes a rotating rod disposed at the front end of the take-up shell.

[0012] As a further embodiment of this utility model, the winding mechanism further includes a guide hole opened at the connection between the winding shell and the connecting line, and a winding shaft rotatably installed at the center of the winding shell.

[0013] As a further embodiment of this utility model: the connecting wire is coiled and wound inside the winding shell, one end of the connecting wire is fixedly connected to the hammer, and the other end of the connecting wire is fixedly connected to the winding shaft.

[0014] As a further improvement of this utility model: the connecting line passes through the bottom of the guide hole, and the winding shaft passes through the middle of the winding shell and is fixedly connected to one end of the rotating rod.

[0015] As a further embodiment of this utility model, the limiting mechanism further includes a limiting hole on the surface of the winding shell, a connecting hole on the surface of the rotating rod, an insert rod penetrating inside the connecting hole, and a pull ring fixed to the front end of the insert rod.

[0016] As a further improvement of this utility model: the connecting hole and the limiting hole are the same size, and the limiting holes are evenly distributed at equal intervals along the center position of the winding shell.

[0017] As a further embodiment of this utility model, the fixing mechanism further includes a magnet fixed to one side of the fixing plate, a fixing nail penetrating inside the fixing plate, a connecting sleeve fixed at the connection between the fixing nail and the fixing plate, and a hanging hole opened on the other side surface of the fixing plate.

[0018] As a further improvement of this utility model: the connecting sleeve is threadedly connected to the fixing nail, and the axis of the fixing nail coincides with the center line of the hanging hole.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model, through the setting of the adjustment mechanism, allows the winding mechanism to slide the adjustment slider inside the adjustment groove. With the help of the limit screw, the position of the adjustment slider is determined. When it is necessary to fine-tune the position of the plumb bob device, it is not necessary to repeatedly disassemble the plumb bob device through the fixing mechanism to meet the position adjustment of the plumb bob device.

[0021] This utility model, through the setting of a limiting mechanism, can limit the position of the rotating rod. When the insertion rod is inserted into the connection hole and the limiting hole, it can prevent the rotating rod from rotating without reason, causing the connecting wire to come out. Through the setting of a fixing mechanism, the plumb bob device can be fixed in a variety of ways to meet the different usage environments in construction engineering. Attached Figure Description

[0028] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example

[0031] Please see Figure 1 , Figure 2 and Figure 5 This is the first embodiment of the present invention, which provides a plumb bob device for preventing knotting in construction engineering, comprising:

[0032] The winding mechanism 1 includes a winding shell 101, a connecting line 6 disposed inside the winding shell 101, and a hammer 5 fixed to the bottom of the connecting line 6;

[0033] The adjustment mechanism 2 includes a support plate 201 slidably mounted on the top of the take-up shell 101, an adjustment groove 202 formed on the surface of the support plate 201, a limiting groove 203 formed on the side of the support plate 201, an adjustment slider 204 disposed between the take-up shell 101 and the support plate 201, and a limiting screw 205 threadedly connected to the side of the adjustment slider 204. The end diameter of the limiting screw 205 is larger than the width of the limiting groove 203.

[0034] The fixing mechanism 3 includes a fixing plate 301 fixed to the end of the support plate 201;

[0035] The limiting mechanism 4 includes a rotating rod 401 located at the front end of the winding shell 101.

[0036] Specifically, the winding mechanism 1 also includes a guide hole 102 opened at the connection between the winding shell 101 and the connecting line 6, and a winding shaft 103 rotatably mounted at the center of the winding shell 101.

[0037] Furthermore, the rotating take-up shaft 103 can drive the connecting wire 6 to be wound inside the take-up housing 101. The connecting wire 6 enters the take-up housing 101 through the guide hole 102, thereby preventing the connecting wire 6 from scattering and mixing together, which would cause the connecting wire 6 to become knotted.

[0038] Specifically, the connecting wire 6 is coiled and wound inside the take-up housing 101, with one end of the connecting wire 6 fixedly connected to the hammer 5 and the other end of the connecting wire 6 fixedly connected to the take-up shaft 103.

[0039] Furthermore, the connecting wire 6 can be wound inside the take-up housing 101 via the rotating take-up shaft 103.

[0040] Specifically, the connecting line 6 passes through the bottom of the guide hole 102, and the take-up shaft 103 passes through the middle of the take-up shell 101 and is fixedly connected to one end of the rotating rod 401.

[0041] Furthermore, the rotating rod 401 can drive the take-up shaft 103 to rotate.

[0042] In use, after the entire plumb bob device is fixed in a suitable position by the fixing mechanism 3, the position of the winding mechanism 1 can be adjusted by the adjusting mechanism 2, that is, the position of the plumb bob 5 can be adjusted. When adjusting, first rotate the limiting screw 205 so that the end of the limiting screw 205 is away from the support plate 201. By pulling the limiting screw 205, the adjusting slider 204 at the end of the limiting screw 205 can be driven to slide inside the adjusting groove 202. After adjusting the adjusting slider 204 to a suitable position, rotate the limiting screw 205 so that the limiting screw 205 can enter the adjusting slider 204 inward. At this time, the end of the limiting screw 205 abuts against the support plate 201, thereby determining the position of the adjusting slider 204. There is no need to repeatedly adjust the fixing mechanism 3 to disassemble the plumb bob device. Rotating the rotating rod 401 can drive the winding shaft 103 to rotate. When the winding shaft 103 rotates, the connecting line 6 can be wound up and unwound. When the plumb bob 5 is needed, the plumb bob 5 descends and the connecting line 6 is unwound. When the winding shaft 103 winds up, the plumb bob 5 rises.

[0043] In summary, the anti-knotting plumb bob device for construction engineering, through the adjustment mechanism 2, can slide inside the adjustment groove 202 via the adjustment slider 204 in the winding mechanism 1. The position of the adjustment slider 204 is determined by the limit screw 205. When the position of the plumb bob device needs to be finely adjusted, there is no need to repeatedly disassemble the plumb bob device through the fixing mechanism 3 to meet the position adjustment of the plumb bob device. Example

[0044] Please see Figure 1 and Figure 4 This is the second embodiment of the present invention, which provides an improved design for a plumb bob device for preventing knotting in construction engineering.

[0045] Specifically, the limiting mechanism 4 also includes a limiting hole 402 opened on the surface of the take-up shell 101, a connecting hole 405 opened on the surface of the rotating rod 401, an insert rod 404 passing through the connecting hole 405, and a pull ring 403 fixed to the front end of the insert rod 404.

[0046] Furthermore, the pull ring 403 can pull the insertion rod 404 to move. When the insertion rod 404 is inserted into the connection hole 405 and the limiting hole 402, it can limit the position of the rotating rod 401 to prevent the rotating rod 401 from rotating without reason, which would cause the connecting wire 6 to come out.

[0047] Specifically, the connecting hole 405 and the limiting hole 402 are the same size, and the limiting hole 402 is evenly distributed at equal intervals along the center position of the winding shell 101.

[0048] Furthermore, the multiple limiting holes 402 provided can satisfy the position determination of the rotating rod 401.

[0049] In use, once the length of the connecting wire 6 is determined, insert the rod 404 into the connecting hole 405 and the limiting hole 402. At this time, the position of the rotating rod 401 is determined and it cannot continue to rotate. When it is necessary to rotate the rotating rod 401, pull the pull ring 403. The pull ring 403 will drive the rod 404 to disengage from the connecting hole 405 and the limiting hole 402, thus unlocking the rotating rod 401.

[0050] In summary, the limiting mechanism 4 can limit the position of the rotating rod 401. When the insertion rod 404 is inserted into the connection hole 405 and the limiting hole 402, the rotating rod 401 can be prevented from rotating without reason, which would cause the connecting wire 6 to come out. Example

[0051] Please see Figure 2 and Figure 3 This is the third embodiment of the present invention, which provides a data processing system for a plumb bob device for preventing knotting in construction engineering.

[0052] Specifically, the fixing mechanism 3 also includes a magnet 305 fixed to one side of the fixing plate 301, a fixing nail 302 penetrating inside the fixing plate 301, a connecting sleeve 303 fixed at the connection between the fixing nail 302 and the fixing plate 301, and a hanging hole 304 opened on the other side surface of the fixing plate 301.

[0053] Furthermore, the fixing mechanism 3 adopts multiple fixing methods. The hanging hole 304 can hang the plumb bob on the iron nail to fix the plumb bob; while the fixing nail 302 can be inserted into the wooden board to fix the plumb bob; and the magnet 305 can be attached to the iron scaffold or iron plate to fix the plumb bob, which can meet the different usage environments in construction engineering.

[0054] Specifically, the connecting sleeve 303 is threadedly connected to the fixing pin 302, and the axis of the fixing pin 302 coincides with the center line of the hanging hole 304.

[0055] Furthermore, the connecting sleeve 303 is fixed inside the fixing plate 301. By rotating the fixing nail 302, the fixing nail 302 can be inserted into the wooden board through the thread inside the connecting sleeve 303.

[0056] When in use, different fixing methods can be selected according to different usage environments. When fixing, the hanging hole 304 can hang the plumb bob on the iron nail, the fixing nail 302 can be inserted into the wooden board, and the magnet 305 can be attracted to the iron scaffold or iron plate.

[0057] In summary, the fixing mechanism 3 allows for the use of various fixing methods to secure the plumb bob device, meeting the needs of different usage environments in construction engineering.
