Description

Technical Field

[0001] This utility model pertains to manual measuring tools, specifically a level. Background Technology

[0002] A spirit level is used to measure horizontality, angles, and verticality. Besides relying on the measured area via its reference surface, it sometimes needs to be attached to the measured area using a magnet. Therefore, securely and reliably assembling the magnet to the level increases its durability. Currently, the magnets in spirit levels are typically fixed in blind holes in the level body using methods such as embedding or gluing, which is not secure enough. Utility Model Content

[0003] This invention addresses the instability caused by the magnets in existing spirit levels being fixed to blind holes in the spirit level body through methods such as embedding or bonding, and provides a spirit level that can securely and reliably assemble the magnets into the spirit level body.

[0004] To achieve the above objectives, the present invention provides a spirit level comprising a spirit level body and a spirit level bubble mounted on the spirit level body, with at least two magnets spaced apart along the length of the spirit level body. The spirit level is characterized in that each magnet is fixed to the spirit level body via a fixing structure, the fixing structure comprising a first receiving hole, a second receiving hole, and a base. The first receiving hole extends from the side of the spirit level body into the body of the spirit level body. The second receiving hole intersects with the first receiving hole and extends from the body of the spirit level body towards the bottom surface. The base is located in the first receiving hole, and the outline of the base is larger than the outline of the second receiving hole. The magnet is fixed to the base and located in the second receiving hole. The first receiving hole is covered and blocked.

[0005] When this spirit level is placed against the part being measured with its bottom surface as the reference surface, it can be attracted to the part being measured by a magnet. Since the magnet is fixed to the base and located in the second receiving hole, one end of the magnet can be as close as possible to the bottom surface, resulting in a strong magnetic attraction.

[0006] This level is designed so that the base is positioned within the first receiving hole, and the profile of the base is larger than that of the second receiving hole. Therefore, the base is constrained within the first receiving hole and will not detach from it through the second receiving hole. The magnet is fixed to the base, allowing for a more secure and reliable assembly, unlike the less secure fit caused by blind holes where the magnet is embedded or bonded to the level body. Thus, when the magnet is fixed to the base within the second receiving hole, it can be securely and reliably assembled to the level body.

[0007] Preferably, the seat is located at the edge of the second receiving hole. This securely fixes the seat to the ruler body and prevents the seat from coming out of the ruler body through the second receiving hole.

[0008] Preferably, a pad is placed inside the first receiving hole, which is pressed between the base and the ruler body, with the pad and the magnet located on opposite sides of the base. Accordingly, the pad presses the base into the first receiving hole to secure it and prevent it from becoming loose.

[0009] Preferably, the side of the ruler body is provided with a groove extending along its length and intersecting with each of the first receiving holes, and the cap is strip-shaped and fitted into the groove. Accordingly, each of the first receiving holes is covered and sealed by a single cap, simplifying the assembly of the cap.

[0010] Preferably, the ruler body is equipped with a retractable pin that extends into the groove, and the cover has a pin hole. The pin is inserted into the pin hole to prevent the cover from moving along the groove. This securely and reliably assembles the cover onto the ruler body.

[0011] Preferably, at least one end of the groove has a port, and the cap is fitted into the groove through the port. Assembly is convenient.

[0012] Preferably, the pin hole is a blind hole. This ensures the cap has a neat shape and prevents the pin from being exposed and touched, thus preventing the pin from coming out of the pin hole and causing the cap to loosen or fall off after it is assembled onto the ruler.

[0013] In one embodiment, the ruler body has grooves on both opposite sides, and a cap is fitted into each groove. The ruler body has a through hole, with both ends extending to the corresponding grooves. Two pins are placed inside the through hole, and an elastic element is placed between the two pins. The pins are inserted into the pin holes of the corresponding caps by the elastic force of the elastic element. Accordingly, two pins are arranged in one through hole, and the two pins use the same elastic element to insert into the corresponding pin holes to fix the two caps. The structure is simple and compact.

[0014] In another embodiment, the ruler body has a blind hole containing a pin and an elastic element. The pin is inserted into the pin hole of the cover by the elastic force of the elastic element. This structure secures one bar magnet, and if the fit between the pin and the pin hole is damaged, it does not affect the securing of the other bar magnet.

[0015] Preferably, the groove includes an opening and a bottom, the width of the bottom being greater than the width of the opening, and the cap includes a main body and an edge, the main body of the cap being located at the opening of the groove, and the edge of the cap being located at the bottom of the groove. This facilitates the insertion of the cap from the port into the groove, reliably fixes the magnet to the groove, and ensures the cap's stability.

[0016] Preferably, the cap and the groove fit tightly together. For example, the cross-sectional profile of the cap is larger than that of the groove, thus ensuring that the cap and the groove are tightly assembled after the cap is installed in the groove. Alternatively, when installing the cap in the groove, adhesive bonding can be used to achieve a tight fit and fixation.

[0017] Preferably, the magnet is fixed to the base to form an assembly, and the height of the assembly is less than the height of the first receiving hole. This facilitates first fixing the magnet to the base to form the assembly, ensuring the firmness of the assembly between the magnet and the base, and then assembling the assembly as a whole into the ruler body, ultimately ensuring the firmness of the magnet assembly.

[0018] Preferably, one end of the magnet is wrapped by the seat to ensure the secure assembly of the magnet.

[0019] Preferably, the second receiving hole extends to the bottom surface in an open shape, or the second receiving hole is covered by the bottom surface. When the second receiving hole extends to the bottom surface in an open shape, the distance between the magnet and the part being measured can be shortened as much as possible, increasing the magnetic attraction of the magnet. When the second receiving hole is covered by the bottom surface, the magnet can be concealed, preventing exposure and damage, and it is equivalent to encapsulating the magnet inside the second receiving hole, ensuring that the magnet will not fall off the ruler.

[0020] Preferably, the side and top surfaces of the level are provided with viewing windows for observing the corresponding spirit level. This allows for viewing the measurement results through different viewing windows when changing the level's orientation and the measurement reference.

[0021] This invention fixes a magnet to a ruler body via a fixing structure. The fixing structure includes a first receiving hole, a second receiving hole, and a seat. The first receiving hole extends from the side of the ruler body into the body. The second receiving hole intersects with the first receiving hole and extends from the body into the bottom surface. The seat is located in the first receiving hole, and the outline of the seat is larger than the outline of the second receiving hole. The magnet is fixed to the seat and located in the second receiving hole. The first receiving hole is covered and blocked. The seat will not detach from the first receiving hole through the second receiving hole. Fixing the magnet to the seat allows for a more secure and reliable assembly, unlike the less secure blind holes caused by embedding or bonding magnets to the ruler body. Therefore, when the magnet is fixed to the seat and located in the second receiving hole, the magnet can be securely and reliably assembled to the ruler body.

[0022] When this spirit level is placed against the part being measured with its bottom surface as the reference surface, it can be attracted to the part being measured by a magnet. Since the magnet is fixed to the base and located in the second receiving hole, one end of the magnet can be as close as possible to the bottom surface, resulting in a strong magnetic attraction.

[0053] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0054] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this utility model are intended to cover non-exclusive inclusion, such as a method or product that includes a series of technical features, not limited to those technical features explicitly listed, but also including other technical features that may be included in the method or product but not explicitly listed.

[0055] In the description of this utility model, it should be understood that the technical features defined by terms such as "first" and "second" which have a sequential concept are only for the purpose of clearly describing the defined technical features and making the defined technical features clearly distinguishable from other technical features, and do not represent that they are named in this way in actual implementation. Therefore, they should not be construed as limitations on this utility model.

[0056] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0057] Figure 1-14 A level ruler is shown, either fully or partially.

[0058] In the illustrated structure, the level includes a level body 100 and a bubble level 200 assembled on the level body.

[0059] The ruler 100 has a bottom surface 133, opposing first and second side surfaces 131 and 132, and a top surface 134. To facilitate multi-angle measurements based on a single measurement reference surface (such as the bottom surface), four bubble levels 200 are mounted on the ruler 100. Figure 5 In the figure, four spirit levels, from left to right, maintain angles of 30°, 45°, 90°, and 0° with the bottom surface 133 of the ruler, respectively. Viewing windows 160 for observing the corresponding spirit levels are provided on the two sides and top surface of the ruler. Thus, when changing the posture of the level for measurement, the measurement results can be viewed through different viewing windows. In other embodiments, the ruler 100 can be other shapes, such as a right angle formed by two perpendicular sides or a triangle formed by three sides, and the number of spirit levels 200 and their angles with the measurement reference plane can be changed as needed.

[0060] Four magnets 700 are spaced apart along the length of the ruler body 100, each magnet 700 being fixed to the ruler body 100 by a fixing structure. The fixing structure includes a first receiving hole 150, a second receiving hole 140, and a seat 600. The first receiving hole 150 extends from the side of the ruler body into the body. The second receiving hole 140 intersects with the first receiving hole 150 and extends from the body of the ruler body towards the bottom surface 133. The seat 600 is located in the first receiving hole 150. The contour D2 of the seat 600 is larger than the contour D1 of the second receiving hole. Taking the second receiving hole 140 as a circular hole and the outer contour of the seat 600 as a cylindrical surface as an example, their contours are represented by their diameters. The magnets 700 are fixed to the seat 600 and located in the second receiving hole 140, while the first receiving hole 150 is covered and blocked by a cover 500.

[0061] When the level is placed against the part being measured with the bottom surface 133 as the reference surface, the level can be attracted to the part being measured by the magnet 700. Since the magnet 700 is fixed to the base and located in the second receiving hole 140, one end of the magnet 700 can be as close as possible to the bottom surface 133, and the magnetic attraction force is large.

[0062] The spirit level is designed so that the base 600 is positioned within the first receiving hole 140, and the outline of the base 600 is larger than the outline of the second receiving hole 140. Therefore, the base 600 is constrained within the first receiving hole 150 and will not disengage through the second receiving hole 140. The magnet 700 is fixed to the base 600, allowing for a more secure and reliable assembly, unlike the less secure fit caused by blind holes where magnets are embedded or bonded to the spirit level body. Thus, when the magnet is fixed to the base and positioned within the second receiving hole, it can be securely and reliably assembled to the spirit level body.

[0063] like Figure 7 , Figure 13 As shown, the seat 600 is located at the edge 141 of the second receiving hole. This securely fixes the seat to the ruler body and prevents the seat from coming out of the ruler body through the second receiving hole.

[0064] like Figure 7 , Figure 14 As shown, a pad 800 is placed inside the first receiving hole 150 and pressed between the base 600 and the ruler 100. The pad 800 and the magnet 700 are located on opposite sides of the base 600. Accordingly, the pad presses the base into the first receiving hole to fix the base and prevent it from becoming loose.

[0065] like Figure 8-11 As shown, the ruler body 100 has grooves 110 extending along its length and intersecting with each of the first receiving holes 150 on both sides. The cover 500 is strip-shaped and fitted into the grooves 110. Accordingly, each of the first receiving holes is covered and sealed by a cover, simplifying the assembly of the cover.

[0066] like Figure 6 , Figure 8-10 As shown, the ruler body 100 is equipped with a retractable pin 300 extending into the groove 110, and the cover 500 is provided with a pin hole 501. The pin 300 is inserted into the pin hole 501 to prevent the cover from moving along the groove. This securely and reliably assembles the cover onto the ruler body. In the illustrated structure, both ends of the groove 110 are provided with ports 111. The cover 500 is fitted into the groove 110 through the ports 111, facilitating assembly. This makes it easy to fit both flexible and rigid strip-shaped covers into the groove. In other embodiments, the groove may be closed at both ends without ports, allowing for the fitting of flexible strip-shaped covers.

[0067] like Figure 6 , Figure 10 As shown, pin hole 501 is a blind hole. This ensures the cover has a neat shape and prevents the pin from being exposed and touched, thus preventing the pin from coming out of the pin hole and causing the cover to loosen or fall off after it is assembled onto the ruler.

[0068] like Figure 6 , Figure 8-10 As shown, the ruler body 100 has grooves 110 on both opposite sides, and a cap 500 is installed in each groove. The ruler body 100 has a through hole 120, with both ends extending to the corresponding grooves 110. Two pins 500 are placed inside the through hole 120, and an elastic element 400 is placed between the two pins 500. The pins are inserted into the pin holes of the corresponding caps by the elastic force of the elastic element. Accordingly, two pins are arranged in one through hole, and the two pins are inserted into the corresponding pin holes by the same elastic element to fix the two caps. The structure is simple and compact. In other embodiments, the ruler body has a blind hole, in which a pin and an elastic element are placed. The pin is inserted into the pin hole of the cap by the elastic force of the elastic element. The pins in this structure fix one bar magnet. When the fit between the pin and the pin hole is damaged, it does not affect the fixation of the other bar magnet.

[0069] like Figure 11As shown, the groove 110 includes an opening 112 and a bottom 113. The width W1 of the bottom is greater than the width W2 of the opening. The cover 500 includes a main body 502 and an edge 503. The main body 502 of the cover is located at the opening 112 of the groove, and the edge 503 of the cover is located at the bottom 113 of the groove. Therefore, it is convenient to insert the cover into the groove from the port, and the magnet can be reliably fixed in the groove, ensuring the cover's firmness.

[0070] In the illustrated structure, the cap 500 and the groove 110 are tightly fitted together. If the cross-sectional profile of the cap is larger than that of the groove, the cap and the groove will be tightly assembled after the cap is fitted into the groove. Alternatively, adhesive bonding can be used to achieve a tight fit when the cap is fitted into the groove.

[0071] like Figure 12-14 As shown, magnet 700 is fixed to base 600 to form assembly 900. The height H2 of assembly 900 is less than the height H1 of the first receiving hole. This facilitates first fixing the magnet to the base to form the assembly, ensuring the secure assembly of the magnet and the base, and then assembling the assembly as a whole into the ruler body, ultimately ensuring the secure assembly of the magnet. Furthermore, one end of magnet 700 is wrapped by base 600 to ensure the secure assembly of the magnet. Therefore, when assembling the magnet, if... Figure 12 As shown, the assembly 900 is inserted into the first receiving hole 150; when the magnet 700 is as shown... Figure 13 When corresponding to the second receiving hole 140, the magnet 700 moves into the second receiving hole 140 as shown. Figure 14 As shown, the seat 600 is located in the second receiving hole 140 and the empty edge 141 of the second receiving hole; then the strip-shaped cover 500 is inserted into the groove 110 to complete the assembly of the magnet.

[0072] In the illustrated structure, the second receiving hole 140 extends to the bottom surface 133 in an open shape, which can minimize the distance between the magnet and the measured part and increase the magnetic attraction of the magnet. In other embodiments, the second receiving hole 140 is shielded by the bottom surface, which can shield the magnet and prevent it from being exposed and damaged. It is also equivalent to encapsulating the magnet in the second receiving hole, ensuring that the magnet will not fall off the ruler.

[0073] In the illustrated structure, both ends of the first receiving hole are exposed on one side, so the first receiving hole is covered by a cap on both sides of the ruler. In other embodiments, one end of the first receiving hole may be exposed on one side and the other end may be closed, in which case it is only necessary to cover the exposed end with a cap.
