Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly to an angle detection tool for building structures. Background Art

[0002] In the field of construction engineering, in order to ensure that the structural angles of buildings meet the design requirements, angle detection tools are required for measurement. The existing angle detection tools have the following problems: 1. The detected angles are relatively single, that is, the same detection tool can only detect specific angles. For example, it can only perform verticality detection and cannot meet the measurement requirements of other degrees; 2. The functions are relatively single, and it is difficult to quickly switch between a vertical ruler and a straight ruler. When angle and length measurements are required, the staff has to replace different detection tools, which not only increases the complexity of the operation but also reduces work efficiency. Moreover, in some special measurement scenarios, such as narrow spaces or high-altitude operations, frequent tool replacement may also pose safety hazards; 3. The non-adjustability of the measured length. The length range that the existing tools can detect is usually fixed or the adjustment range is very limited. When encountering building structures with large changes, the corresponding measurement requirements cannot be met. Summary of the Invention

Detailed implementation mode

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0047] Please refer to Figure 1 - Figure 12 , the present invention provides a technical solution for an angle detection tool for building structures: the angle detection tool for building structures includes a main body column 1, the end of the main body column 1 is rotatably connected to a secondary body column 2, a limiting groove 412 is provided on the side wall of the secondary body column 2, and a locking component for locking the secondary body column 2 is further provided on the main body column 1;

[0048] The locking component includes a locking fixed plate 401 connected to one side wall of the main body column 1. The side wall of the locking fixed plate 401 is provided with an avoidance groove 407 with a small opening and a large inner cavity. A first sliding hole 415 that can communicate with the limiting groove 412 is formed at the inner opening of the avoidance groove 407, and a second sliding hole 409 is formed at the outer opening of the avoidance groove 407 and penetrates through the outer wall of the locking fixed plate 401;

[0049] The locking component further includes a limiting head 408 slidably arranged in the avoidance groove 407. A locking section 416 is connected to the inner end of the limiting head 408, a pulling column 410 passing through the second sliding hole 409 is connected to the outer end of the limiting head 408, and an anti - detachment head 414 located outside the second sliding hole 409 is connected to the end of the pulling column 410;

[0050] The locking component further includes a locking spring 411 sleeved on the pulling column 410. The two ends of the locking spring 411 respectively abut against the limiting head 408 and the groove wall of the avoidance groove 407, so that: the locking section 416 passes through the first sliding hole 415 and is placed in the first sliding hole 415.

[0051] In this embodiment, scale marks are provided on both the main column 1 and the auxiliary column 2, so that the corresponding angles and lengths can be measured easily. In the locking assembly, when the avoidance groove 407 is directly opposite to the limiting groove 412, and the locking section 416 can be inserted into the limiting groove 412, the angle between the auxiliary column 2 and the main column 1 is exactly 90°, so this embodiment is suitable for measuring the verticality of the wall structure. When measuring other angles (not 90°) or lengths, the anti-slip head 414 can be pulled outward to make the limiting head 408 disengage from the limiting groove 412, so that the auxiliary column 2 can be rotated as needed to facilitate the corresponding measurement. Among them, the locking spring 411 can give the pulling column 410 an elastic support force, so that the limiting head 408 always maintains a tendency to pass through the first sliding hole 415.

[0052] It can be seen that the locking component designed in this embodiment is mainly for the locking work when the auxiliary body column 2 and the main column 1 are at a vertical angle. In this way, the stability of the verticality detection work can be improved; when the locking component is unlocked, the auxiliary body column 2 can be switched to other angles (including 180°) relative to the main column 1, so that other angles and lengths can be measured conveniently.

[0053] In order to realize the rotatable connection between the auxiliary body column 2 and the main body column 1, preferably, the end of the main body column 1 is connected with an articulated frame, and the articulated frame has two spaced connection ears A101;

[0054] The end of the auxiliary body column 2 is connected with a connecting ear B201 which can be placed between the two connecting ears A101. The connecting ear B201 passes through and is linked with a linking column 3. The two ends of the linking column 3 pass through the two connecting ears A101 respectively.

[0055] In this embodiment, when the auxiliary body column 2 is rotated, the two connecting ears A101 can limit the connecting ears B201 and the linkage column 3 to prevent the auxiliary body column 2 from shaking greatly during the rotation process and affecting the accuracy of the measurement.

[0056] Preferably, the outer side wall of the locking and fixing plate 401 is connected with a mounting box 403;

[0057] One end of the linkage column 3 passes through the locking and fixing plate 401 and is connected to the switching assembly 4;

[0058] The switching assembly 4 includes a first limiting gear 402 sleeved on the end of the linkage column 3 and located outside the locking fixing plate 401;

[0059] The switching assembly 4 further includes a sliding column 404 slidably disposed in the installation box 403, the inner end of the sliding column 404 is connected to a second limiting gear 406 that can cooperate with the first limiting gear 402, and the outer end of the sliding column 404 passes through the installation box 403 and is connected to a pulling head 413 located outside the installation box 403;

[0060] The switching assembly 4 also includes a switching spring 405 sleeved on the sliding column 404, and the two ends of the switching spring 405 respectively abut against the second limiting gear 406 and the inner wall of the installation box 403, so that: the second limiting gear 406 abuts against the first limiting gear 402 and the two are in a meshing state.

[0061] In this embodiment, the switching assembly 4 is suitable for locking when the angle between the auxiliary column 2 and the main column 1 is non-vertical. The outer wall of the first limiting gear 402 and the inner wall of the second limiting gear 406 are provided with a plurality of teeth meshing with each other.

[0062] During application, when it is necessary to adjust the angle between the auxiliary column 2 and the main column 1, the pulling head 413 is pulled outward to make the teeth of the second limit gear 406 disengage from the teeth of the first limit gear 402, and then the auxiliary column 2 is rotated relative to the main column 1 to a specific angle, including 180°, that is, a straight line state, and then the pulling head 413 is reset to make the first limit gear 402 re-engage with the first limit gear 402 under the elastic support of the switching spring 405. In this way, the aforementioned angle state can be locked.

[0063] In order to facilitate sliding of the pulling head 413 , a plurality of anti-slip grooves are provided on the annular surface of the pulling head 413 .

[0064] In order to improve the sliding stability of the sliding column 404, preferably, a clearance hole 417 for the sliding column 404 to pass through is opened on the installation box 403, and a limiting protrusion 418 is provided on the inner wall of the clearance hole 417;

[0065] The sliding column 404 is provided with a limiting groove 419 which can cooperate with the limiting protrusion 418 .

[0066] In this embodiment, Figure 6 As shown, limiting protrusions 418 are provided on both sides of the inner wall of the clearance hole 417 , and correspondingly, limiting grooves 419 cooperating with the limiting protrusions 418 are provided on both sides of the sliding column 404 .

[0067] Preferably, it also includes a display component 7;

[0068] The display assembly 7 includes a display fixing plate 701 connected to the other side wall of the main column 1, and a dial 702 is connected to the display fixing plate 701;

[0069] The other end of the linkage column 3 passes through the display fixing plate 701 and the scale plate 702 in sequence and is connected to an indicating needle 703 located in the scale plate 702 .

[0070] In this embodiment, when the secondary body column 2 is rotated, the linkage column 3 and the indicating needle 703 are driven to rotate. By reading the relative position of the indicating needle 703 relative to the scale disk 702, the rotation angle of the secondary body column 2 can be known.

[0071] As Figure 2 , Figure 6 and Figure 7 shown, the locking fixing plate 401 is located outside a connecting ear A101, while the display fixing plate 701 is located outside another connecting ear A101. The locking fixing plate 401 and the display fixing plate 701 can jointly limit the rotation state of the secondary body column 2.

[0072] To prevent impurities from entering the scale disk 702, preferably, a shielding piece 704 made of a transparent material that shields the indicating needle 703 is connected to the outer end of the scale disk 702.

[0073] Preferably, telescopic sliding openings 606 and adjusting through openings 607 communicating with the telescopic sliding openings 606 are provided on both the main body column 1 and the secondary body column 2, and rotation holes 604 communicating with the adjusting through openings 607 are provided on both the main body column 1 and the secondary body column 2;

[0074] A telescopic column 601 is slidably connected to the telescopic sliding opening 606. An adjusting seat 605 is connected to the end of the telescopic column 601, and a threaded hole 602 is provided on the adjusting seat 605;

[0075] An adjusting assembly 6 for adjusting the position of the telescopic column 601 is arranged in the adjusting through opening 607. The adjusting assembly 6 includes a threaded column 603 rotatably arranged in the adjusting through opening 607 and cooperating with the threaded hole 602. The top end of the threaded column 603 passes through the rotation hole 604 and is connected with an adjusting handle 608.

[0076] In this embodiment, scale marks are provided on the telescopic column 601 to facilitate measuring the corresponding length. When the lengths of the main body column 1 and the secondary body column 2 are limited, the adjusting handle 608 can be rotated to rotate the threaded column 603. Through the cooperation of the threaded column 603 and the adjusting seat 605, the telescopic column 601 can be slid out of the main body column 1 or the secondary body column 2 to compensate for the corresponding length measurement.

[0077] The telescopic sliding opening 606 can penetrate the bottom end of the main body column 1 or the secondary body column 2.

[0078] To improve the sliding stability of the telescopic column 601, preferably, a positioning groove 609 is provided on the side wall of the telescopic column 601;

[0079] A positioning protrusion 610 capable of cooperating with the positioning groove 609 is provided on the inner wall of the telescopic sliding opening 606.

[0080] In this embodiment, as Figure 8As shown, positioning grooves 609 can be provided on both sides of the telescopic column 601. Correspondingly, positioning protrusions 610 that cooperate with the positioning grooves 609 are provided on both sides of the inner wall of the telescopic sliding opening 606.

[0081] Preferably, support assemblies 8 are provided on both sides of the main column 1;

[0082] The support assembly 8 includes a fixed head 801 connected to the side wall of the main column 1. A rotating column 802 that can rotate relative to the fixed head 801 is connected through the fixed head 801. The two rotating columns 801 are connected to drive the same support plate 803.

[0083] In this embodiment, when the support plate 803 is rotated to a state where the angle with the main column 1 is 90°, the contact area with the wall structure can be increased. In this way, the measurement stability can be improved; when this embodiment needs to be carried, the support plate 803 is rotated to a state where it fits with the main column 1 to reduce the occupied space and facilitate carrying.

[0084] Among them, to facilitate exerting force on the support plate 803, a hand-held hole 807 is provided on the support plate 803, and the hand-held hole 807 can be arc-shaped.

[0085] Preferably, a limiting assembly for limiting the position of the support plate 803 is further provided on the side wall of the main column 1;

[0086] A limiting installation groove 804 with a small opening and a large inner cavity is provided on the side wall of the main column 1. A limiting plate 808 located in the inner cavity of the limiting installation groove 804 is connected in the limiting installation groove 804 through a limiting spring 805. A resistance block 806 that can pass through the opening of the limiting installation groove 804 is connected to the outside of the limiting plate 808;

[0087] The limiting spring 805 acts on the limiting plate 808, so that: the resistance block 806 abuts against the support plate 803.

[0088] In this embodiment, the limiting assembly is used to position the state of the support plate 803. Specifically, the limiting spring 805 can give the resistance block 806 a supporting force to abut against the support plate 803, so as to limit the real-time position state of the support plate 803. To facilitate the rotation of the support plate 803, the working surface of the resistance block 806 acting on the support plate 803 should be arc-shaped. The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific embodiments of the present invention are only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, other embodiments obtained without departing from the technical solution of the present invention should be included within the protection scope of the present invention.
