Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a portable measuring device for decoration and renovation. Background Art

[0002] When measuring the verticality of a wall during renovation, a plumb bob is usually used. However, the plumb line on the existing plumb bob is easily tangled when not in use, making it inconvenient to use again.

[0003] Publication No. CN211626494U discloses a portable measuring device for decoration design, including a pendant, a hanging ring fixedly connected to the middle of the upper end of the pendant, a plumb line tied to the hanging ring, and a connecting block fixedly connected to the end of the plumb line away from the hanging ring. A line accommodating cavity is bored inside the pendant, and a rotating hole and a rotating groove are respectively provided on the upper and lower sides of the line accommodating cavity. The rotating hole and the rotating groove are all bored on the pendant, and the rotating hole, the rotating groove and the line accommodating cavity are located on the same central axis. A reel is inserted into the rotating hole, and the reel passes through the rotating hole and the line accommodating cavity and extends into the rotating groove. The outer end of the reel near the lower side is fixedly connected to a connecting ring, which matches the connecting block. Four evenly distributed long wire entry holes are bored on the outer end of the pendant, and the long wire entry holes match the line accommodating cavity, so that the plumb line can be stored in the pendant, effectively avoiding the situation where the plumb line is tangled, and is convenient for next use. However, the following problems still exist in the actual use of this patent:

[0004] When the above device is in use, all the lines need to be pulled out from the line cavity, held in the hand, and then used. As a result, every time the line is stored, all the lines need to be reeled in regardless of the actual length used, which is inconvenient to use. In addition, the reel is small in size, and it is extremely inconvenient to rotate it a large number of times by hand.

[0005] A portable measuring device for decoration and renovation is proposed to solve the above problems. Utility Model Content

[0027] See also Figure 1 - Figure 5 The utility model provides a technical solution: a portable measuring device for decoration and renovation, comprising a pendant 1 and a wire body 101 installed on the right side of the top surface of the pendant 1;

[0028] A winding assembly 2 is provided above the pendant 1, and the winding assembly 2 includes a winding bin 201. A locking assembly 3 is provided between the winding bin 201 and the pendant 1. The top of the winding bin 201 is fixedly connected to a lifting ring 202, the internal rotation of the winding bin 201 is connected to a rotating shaft 203, the middle of the rotating shaft 203 is fixedly connected to a winding wheel 204, and one side of the winding wheel 204 is fixedly connected to a ratchet 205. One side of the winding bin 201 is externally connected to a connecting disk 206, and a crank 207 is installed on one side edge of the connecting disk 206; the crank 207 and the connecting disk 206 facilitate the rotation of the rotating shaft 203, thereby facilitating the winding of the wire body 101.

[0029] Among them, a bending rod 208 is provided above the ratchet 205, and a clamping strip 209 is rotatably connected to the bending rod 208. The clamping strip 209 is engaged with the ratchet 205, and a return spring 213 is rotatably installed on the outer side of the clamping strip 209; the clamping strip 209 allows the ratchet 205 to rotate only in one direction, which facilitates the release and locking of the wire body 101, and there is no need to release all the wire bodies each time.

[0030] The top end of the clamping strip 209 is fixedly connected to a connecting rod 210 , and the top end of the connecting rod 210 is fixedly connected to a pressing plate 211 .

[0031] A avoidance groove 212 is provided on one side of the top of the winding bin 201, and the avoidance groove 212 is slidingly connected to the connecting rod 210. The crank handle 207 is rotatably connected to the edge of the side of the connecting disk 206 away from the winding bin 201, and the bending rod 208 is fixedly connected to the winding bin 201.

[0032] The end of the reset spring 213 away from the clamping strip 209 is rotatably connected to the inner wall of the winding bin 201, the bottom end of the wire body 101 is fixedly connected to the top of the pendant 1, and the top end of the wire body 101 passes through the bottom of the winding bin 201 and is fixed on the winding wheel 204; the force transmitted to the ratchet 205 by the pendant 1 through the rotating shaft 203 will cause the ratchet 205 to generate an extrusion force on the clamping strip 209. At this time, the reset spring 213 will be subjected to the extrusion force but will not be deformed.

[0033] A connecting shaft is fixedly connected to the middle of the connecting disk 206 . One end of the connecting shaft away from the connecting disk 206 extends into the winding bin 201 and is fixedly connected to the end of the rotating shaft 203 .

[0034] The locking assembly 3 includes a first docking ring 301 fixed to the bottom of the winding bin 201, a second docking ring 302 is fixedly connected to the top surface of the pendant 1, a fixing bar 303 is fixedly connected to the outer side of the second docking ring 302, a protrusion 304 is fixedly connected to the outer side of the first docking ring 301, a movable rod 305 is slidably connected to the middle part of the protrusion 304, one end of the movable rod 305 is fixedly connected to a pull ring 306, the other end of the movable rod 305 is fixedly connected to a trapezoidal block 307, and a first spring 309 is fixedly connected between the trapezoidal block 307 and the protrusion 304; the first spring 309 is in the initial state under normal conditions, and the wire body 101 passes through the center of the first docking ring 301 and the second docking ring 302.

[0035] The first spring 309 is sleeved on the outside of the movable rod 305 .

[0036] A groove 308 is provided on one side of the top of the fixing bar 303, and the groove 308 is engaged with the trapezoidal block 307; the groove 308 can limit the position of the fixing bar 303 by engaging with the trapezoidal block 307, so that the second docking ring 302 and the first docking ring 301 fit together.

[0037] Working principle: Before using this portable measuring device for decoration, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5As shown, first, the whole device has a hand-holding point by holding the lifting ring 202, which is convenient for carrying and transporting. When the device needs to be used, the thumb is used to push the pressure plate 211 while holding the lifting ring 202, so that the clamping bar 209 rotates and disengages the ratchet 205. At this time, the pull ring 306 is pulled to move the movable rod 305, thereby pulling the trapezoidal clamping block 307 out of the groove 308. At this time, the pendant 1 drives the fixing bar 303 to fall by its own weight, thereby driving the rotating shaft 203 and the winding wheel 204 to rotate through the wire body 101, and finally the pendant 1 can be quickly dropped and released;

[0038] When it falls to the estimated height, the thumb releases the pressure plate 211, causing the return spring 213 to push the clamping bar 209 to rotate and reset, thereby re-engaging it with the ratchet 205. At this time, the ratchet 205 and the rotating shaft 203 cannot rotate, so that the line body 101 can be quickly released and stopped quickly to maintain the target length;

[0039] When the wire 101 is not needed, the crank 207 is held and the connecting disk 206 is shaken to rotate the shaft 203, so that the ratchet 205 can push the clamping strip 209 out of position through the inclined surface, so that the shaft 203 can rotate smoothly, and finally all the wires 101 are wound on the winding wheel 204.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
