Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a retractable vertical component verticality detection tool. Background Technology

[0002] In building construction, equipment installation and other scenarios, the verticality of vertical components is a key quality indicator that directly affects structural stability, aesthetics and subsequent installation accuracy.

[0003] A template verticality testing tool disclosed in Chinese Patent Publication No. CN214251022U, with its three telescopic joints and snap-fit ​​structure, allows for adjustment of the main telescopic rod's length according to the actual inspection height requirements. However, based on existing verticality testing tools and technologies in related fields, traditional tools are mostly multi-segment sleeve structures. Adjustment requires stretching each segment to the target length, with each segment requiring a separate locking device. The stretching length of each segment needs to be manually aligned with the scale, which can easily lead to increased total length deviation and measurement error due to accumulated errors. Furthermore, the locking mechanism of traditional tools relies on friction or mechanical snap-fits, which are prone to failure under external forces such as vibration and collisions. This results in a decrease in the fit between the scale edge and the vertical component, affecting the testing accuracy. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a retractable vertical component verticality detection tool.

[0005] The objective of this utility model is achieved through the following technical solution: a retractable vertical component verticality testing tool, comprising a receiving cylinder and a plumb bob. Folding measuring components are provided at both the upper and lower ends of the receiving cylinder. The plumb bob's suspension line is mounted on the folding measuring components above the receiving cylinder. A synchronization component is provided inside the receiving cylinder for allowing the two folding measuring components to slide towards each other. The synchronization component includes a gear rotatably disposed inside the receiving cylinder. Two racks are symmetrically meshed on the outer surface of the gear. Both racks are longitudinally slidably disposed inside the receiving cylinder. The two folding measuring components are respectively fixedly mounted on the ends of the two racks. An adjustment component is provided on the receiving cylinder for controlling the rotation of the gear and for self-locking.

[0006] Preferably, the folding measuring assembly includes a fixed base, and a top block and a scale are diagonally hinged inside the fixed base via a spring shaft.

[0007] Preferably, a magnetic block is embedded on the side of the top block facing the scale, and the scale is made of iron.

[0008] Preferably, the adjusting assembly includes a splined shaft, a worm gear, and a worm. The worm gear and the worm are both rotatably disposed inside the receiving cylinder. The worm gear meshes with the worm. The splined shaft is rotatably disposed laterally inside the receiving cylinder. The gear and the worm gear are both splinedly connected to the splined shaft.

[0009] Preferably, the receiving cylinder has first rotating holes at both ends of the worm, and both ends of the worm are connected to the first rotating holes through bearings. A knob is fixedly installed at one end of the worm outside the receiving cylinder.

[0010] Preferably, the receiving cylinder has second rotating holes at both ends of the spline shaft, and both ends of the spline shaft are connected to the second rotating holes through bearings.

[0011] Preferably, each of the two racks has a groove on the side facing the inner wall of the receiving cylinder, and a slider is fixedly provided on the inner wall of the receiving cylinder at the position corresponding to the two grooves. The slider has a T-shaped cross-section, and the groove and the slider slide in cooperation.

[0012] Preferably, a suspension area is provided on the side of the scale located above the receiving cylinder, and the suspension line of the plumb bob is installed in the suspension area.

[0013] The beneficial effects of this retractable vertical component verticality detection tool are as follows: by setting up a folding measurement component, a synchronization component, and an adjustment component, the distance between the two folding measurement components can be precisely adjusted, thereby enabling the detection of vertical components at different heights. Furthermore, by utilizing the reverse self-locking function of the adjustment component, the distance between the two folding measurement components will not expand or contract on its own even if subjected to external force collisions or vibrations after adjustment, ensuring that the measurement benchmark remains stable throughout the detection process.

[0027] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0028] like Figures 1 to 10As shown, a retractable vertical component verticality testing tool includes a receiving cylinder 1 and a plumb bob 2. Folding measuring components 3 are provided at both the upper and lower ends of the receiving cylinder 1. The suspension line of the plumb bob 2 is mounted on the folding measuring components 3 above the receiving cylinder 1. A synchronization component 4 is provided inside the receiving cylinder 1 to allow the two folding measuring components 3 to slide towards each other. The synchronization component 4 includes a gear 401 rotatably disposed inside the receiving cylinder 1. Two racks 402 are symmetrically meshed on the outer surface of the gear 401. Both racks 402 are longitudinally slidable inside the receiving cylinder 1. The measuring components 3 are fixedly installed at the ends of the two racks 402 respectively. The receiving cylinder 1 is provided with an adjusting component 5 for controlling the rotation of the gear 401 and self-locking. The side of the two racks 402 facing the inner wall of the receiving cylinder 1 is provided with a sliding groove 4021. The inner wall of the receiving cylinder 1 is provided with a slider 103 at the position corresponding to the two sliding grooves 4021. The cross-sectional shape of the slider 103 is T-shaped. The sliding groove 4021 and the slider 103 slide in cooperation. By using the sliding groove 4021 and the slider 103 to slide in cooperation, the stability of the two racks 402 when sliding in opposite directions can be ensured.

[0029] like Figure 1 , Figure 2 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the folding measuring assembly 3 includes a fixed base 301. Inside the fixed base 301, a top block 303 and a scale 304 are diagonally hinged via a spring shaft 302. A magnet 3031 is embedded on the side of the top block 303 facing the scale 304. The scale 304 is made of iron. When the top block 303 and the scale 304 are flipped into the fixed base 301, the magnet 3031 allows the top block 303 and the scale 304 to be attracted together. At this time, the attraction force between the top block 303 and the scale 304 is greater than the torque of the spring shaft 302, thereby making the top block 303 and the scale 304 attract together. When not subjected to external force, the scale 304 can remain inside the fixed base 301, reducing the overall space occupied. The scale 304 located above the receiving cylinder 1 has a suspension area 305 (composed of a groove and a column) on its side. The plumb line 2 is installed in the suspension area 305. The plumb line 2 can be tied to the suspension area 305 or stuck in the suspension area 305. When the gear 401 rotates, the two racks 402 will drive the two folding measuring components 3 to slide in opposite directions, thereby adjusting the distance between the two folding measuring components 3 as needed, and thus being able to detect vertical components of different heights.

[0030] like Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8As shown, the adjusting component 5 includes a splined shaft 501, a worm gear 502, and a worm 503. Both the worm gear 502 and the worm 503 are rotatably mounted inside the receiving cylinder 1. The worm gear 502 meshes with the worm 503, and the worm gear 503 transmission has a high transmission ratio characteristic. Fine adjustment of the worm 503 can achieve precise control of the distance between the two folding measuring components 3, meeting the requirements of high-precision testing. Simultaneously, the meshing of the worm gear 502 and the worm 503 has a reverse self-locking function (i.e., the worm gear 502 cannot drive the worm 503 to rotate). After the distance between the two folding measuring components 3 is adjusted, even if subjected to external force collision or vibration, the two folding measuring components 3 will not extend or retract on their own, ensuring that the measurement reference remains stable during the testing process. The splined shaft 501 is laterally rotatably mounted inside the receiving cylinder 1. The gear 401 and the worm gear 502 are both splinedly connected to the splined shaft 501. By rotating the worm 503 through the knob 5031, the worm 503... 03. The worm gear 502 is controlled to rotate, and then the spline shaft 501 is used to drive the worm gear 502 to rotate. The spline shaft 501 then drives the gear 401 to rotate. The receiving cylinder 1 has second rotation holes 102 at both ends of the spline shaft 501. Both ends of the spline shaft 501 are connected to the second rotation holes 102 through bearings (not labeled in the figure). The bearings can reduce the friction when the spline shaft 501 rotates and improve the stability of the spline shaft 501 during rotation. The receiving cylinder 1 has first rotation holes 101 at both ends of the worm 503. Both ends of the worm 503 are connected to the first rotation holes 101 through bearings (not labeled in the figure). A knob 5031 is fixedly installed at one end of the worm 503 outside the receiving cylinder 1. The bearings can reduce the friction when the worm 503 rotates and improve the stability of the worm 503 during rotation.

[0031] The work process is as follows:

[0032] S1: As Figure 1 and Figure 10 As shown, during use, by controlling the top block 303 and the scale 304 to flip outwards from the fixed base 301, the spring of the spring shaft 302 will be released, thereby keeping the top block 303 and the scale 304 in a horizontal state.

[0033] S2: As Figure 1 and Figure 2 As shown, after the top blocks 303 and scale 304 on both the upper and lower sides are flipped out, the plumb line 2 can be installed on the side of the scale 304 located above the receiving cylinder 1.

[0034] S3: As Figures 4 to 7As shown, after the plumb bob 2 is installed, the worm 503 is rotated by the knob 5031, so that the worm 503 controls the worm wheel 502 to rotate. Then, the worm wheel 502 drives the spline shaft 501 to rotate, and the spline shaft 501 drives the gear 401 to rotate.

[0035] S4: As Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, when gear 401 rotates, the two racks 402 will drive the two folding measuring components 3 to slide in opposite directions, thereby adjusting the distance between the two folding measuring components 3 as needed, and thus being able to detect vertical components of different heights.

[0036] S5: The worm gear 502 and worm 503 transmission has a high transmission ratio. Fine adjustment of the worm 503 can achieve precise control of the distance between the two folded measuring components 3, meeting the requirements of high-precision testing. At the same time, the meshing of the worm gear 502 and worm 503 has a reverse self-locking function. After the distance between the two folded measuring components 3 is adjusted, even if they are subjected to external force collision or vibration, the two folded measuring components 3 will not extend or retract on their own, ensuring that the measurement reference remains stable during the testing process.

[0037] S6: As Figure 2 and Figure 3 As shown, after the spacing between the two folding measuring components 3 is adjusted, the receiving cylinder 1 can be held so that the top block 303 is attached to the vertical component, and the positional relationship between the plumb bob 2 and the scale 304 can be observed to determine the verticality of the vertical component.

[0038] S7: As Figure 1 , Figure 2 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, after use, by adjusting component 5 and coordinating with synchronization component 4, the two folding measuring components 3 are controlled to move closer to each other. Then, the plumb bob 2 can be removed, and the top block 303 and scale 304 are controlled to flip into the interior of the fixed base 301. At this time, the set magnetic block 3031 can make the top block 303 and scale 304 stick together. At this time, the attraction force between the top block 303 and scale 304 is greater than the torque of the spring shaft 302, so that the top block 303 and scale 304 can remain inside the fixed base 301 when there is no external force, thus reducing the overall space occupied.

[0039] The spring shaft 302 and bearing described in this application are both known technologies, therefore their specific structures and working principles are not described in detail.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
