Description

Technical Field

[0001] This application relates to the field of measurement technology, and in particular to a level. Background Technology

[0002] A spirit level, as a common measuring tool, has multiple measurement methods such as horizontal and vertical, and is widely used in fields such as construction, mechanical installation, and carpentry.

[0003] Currently, for ease of measurement, spirit levels typically include digital displays, lighting, and other electrical components. These require batteries to power these components, which are usually housed in a battery compartment that is then embedded into the spirit level's outer casing. Installing the battery compartment involves screws that penetrate the compartment and secure it to the spirit level's outer casing. This installation method has the following drawbacks: it requires drilling screw holes at corresponding locations on the spirit level's outer casing, increasing manufacturing difficulty and the risk of casing deformation, thus reducing the spirit level's accuracy.

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or there may be an intermediate component.

However, their use herein is for illustrative purposes only and is determined based on the exemplary orientations shown in the accompanying drawings, and does not represent the only possible implementation. Since the embodiments disclosed in this application can be arranged in different orientations, these terms indicating orientation are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature and the second feature are in indirect contact through an intermediate medium. Furthermore, "above," "over," and "on top" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] It should be noted that "axial arrangement" means that the overall arrangement direction is along the axial direction, including but not limited to axial extension, and may be at an angle to the axial direction.

[0035] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0036] like Figures 1-10 As shown, this application discloses a spirit level. The spirit level includes a battery box 1, a housing 2, and a mounting bracket 3. The housing 2 has a cavity 210 inside, and an opening 2111 on its side wall for the battery box 1 to pass through. The mounting bracket 3 is disposed within the cavity 210, and has a receiving cavity 310 communicating with the opening 2111, within which the battery box 1 is constrained.

[0037] It is understandable that by setting a mounting bracket 3 inside the outer casing 2, the battery box 1 is installed in the receiving cavity 310 of the mounting bracket 3, without the need for direct installation to the outer casing 2. This avoids the problem of easy deformation of the outer casing 2 caused by opening holes in the outer casing 2 when installing the battery box 1, ensuring the integrity and flatness of the outer casing 2, and helping to maintain the measurement accuracy of the level.

[0038] like Figure 4 and Figure 6As shown, a portion of the battery box 1 is located within the opening 2111. This restricts the movement of the battery box 1 along the length or width of the outer casing 2. Since the battery box 1 is constrained by the mounting bracket 3, the movement of the mounting bracket 3 relative to the outer casing 2 along the length or width of the outer casing 2 is also restricted.

[0039] There are various ways to constrain the battery box 1 and the mounting bracket 3, including snap-fit ​​connections and other methods. In this embodiment, the battery box 1 and the mounting bracket 3 are respectively provided with connection holes for connecting mounting parts 4.

[0040] Furthermore, such as Figure 6 , Figure 8 and Figure 9 As shown, the connection hole on the battery box 1 is defined as the first connection hole 111, and the connection hole on the mounting bracket 3 is defined as the second connection hole 3311. A positioning post 331 is provided on the mounting bracket 3 at the position corresponding to the first connection hole 111. The direction in which the battery box 1 is removed through the opening 2111 is defined as the first direction A. The positioning post 331 extends along the first direction A. The second connection hole 3311 is located on the positioning post 331 and extends along the length of the positioning post 331. It can be understood that this increases the connection area between the mounting component 4 and the mounting bracket 3, thereby increasing the reliability of the connection between the battery box 1 and the mounting bracket 3.

[0041] Mounting component 4 can be a bolt. In this embodiment, mounting component 4 is a screw, and the second connecting hole 3311 is a threaded hole that is threaded to the screw.

[0042] like Figure 6 As shown, the battery box 1 is provided with a positioning groove 11 that engages with the positioning post 331, and the first connecting hole 111 is located on the groove plate of the positioning groove 11. It can be understood that the engagement of the positioning groove 11 and the positioning post 331 can position the battery box 1, which facilitates the installation of the mounting component 4 and also increases the reliability of the connection between the mounting bracket 3 and the battery box 1.

[0043] In addition, such as Figures 1-5 As shown, the outer casing 2 includes a housing 21 and an end cap 22. The cavity 210 is located inside the housing 21. At least one end of the housing 21 is provided with an opening 214 for the mounting bracket 3 to enter and exit the cavity 210. The end cap 22 can open or close the opening 214. Thus, when the mounting bracket 3 needs to be installed, it is only necessary to remove the end cap 22 so that the mounting bracket 3 can enter the cavity 210 through the opening 214.

[0044] In one embodiment, one end of the housing 21 may be provided with an opening 214. In this embodiment, as shown... Figure 3 As shown, both ends of the housing 21 are provided with openings 214, and the mounting bracket 3 can enter the cavity 210 from one of the openings 214.

[0045] Furthermore, such as Figure 7 As shown, the side wall with the opening 2111 on the housing 21 is defined as the first side wall 211, and the side wall on the housing 21 opposite to the first side wall 211 is defined as the second side wall 212. A guide portion and a guide groove 213 are matched and fitted between the second side wall 212 and / or the first side wall 211 and the side wall of the mounting bracket 3. One of the guide portion and the guide groove 213 is provided on the housing 21 and extends along the length of the housing 21, while the other of the guide portion and the guide groove 213 is provided on the mounting bracket 3. Thus, through the guiding fit of the guide portion and the guide groove 213, the movement of the mounting bracket 3 can be guided, facilitating the installation of the mounting bracket 3.

[0046] In one embodiment, the first sidewall 211 and the second sidewall 212 may be arranged at intervals relative to each other along the width direction of the housing 21. In this embodiment, as... Figure 7 As shown, the first sidewall 211 and the second sidewall 212 are arranged at intervals relative to each other along the thickness direction of the housing 21.

[0047] In addition, the length direction of the shell 21 is defined as the second direction B, such as Figure 8 As shown, the mounting frame 3 includes a frame 31, and the area enclosed by the frame 31 is the aforementioned receiving cavity 310. The width direction of the frame 31 is defined as the third direction C, and the third direction C forms an angle with the second direction B. The length direction of the frame 31 is the same as the length direction of the housing 21.

[0048] In this embodiment, such as Figure 8 As shown, the accommodating cavity 310 is provided with two connecting plates 33 arranged at intervals along the second direction B, and each connecting plate 33 is provided with two positioning posts 331 arranged at intervals along the third direction C.

[0049] In addition, at least one corner of the frame 31 is provided with an extension 32 extending outward along the third direction C, and a guide or guide groove 213 is provided on the extension 32.

[0050] Schematic illustration: Extensions 32 are provided at both corners of the frame 31, spaced diagonally apart. In this embodiment, as... Figure 8 As shown, the above-mentioned extension 32 is provided at each of the four corners of the frame 31, and the extensions 32 at the two corners arranged opposite to each other along the second direction B extend in a direction away from each other.

[0051] like Figure 6As shown, the projection of the opening 2111 in the opposite direction of the first direction A is located within the receiving cavity 310, thus preventing the mounting bracket 3 from dislodging from the opening 2111. In this embodiment, the four extensions 32 are located around the opening 2111, so the four extensions 32 cannot dislodge from the opening 2111, thereby preventing the mounting bracket 3 from dislodging from the receiving cavity 310 through the opening 2111.

[0052] Indicatively, a guide groove 213 may be provided on the extension 32. This embodiment is described with the guide part provided on the extension 32 as an example.

[0053] like Figure 7 and Figure 8 As shown, the extension 32 has protrusions 321 on both sides facing the first sidewall 211 and the second sidewall 212, and the protrusions 321 are the aforementioned guide portions. The side of the protrusion 321 facing the frame 31 is defined as the first side surface, which is an inclined surface 3211 that gradually slopes outward along the first direction A. The guide groove 213 has an inclined groove surface 2131 that matches the inclined surface 3211. In this way, the matching arrangement of the inclined surface 3211 and the inclined groove surface 2131 can better guide the installation of the mounting bracket 3.

[0054] like Figure 1 , Figures 3-6 As shown, the aforementioned level also includes a cover plate 5, and a battery box 1 for installing the battery 7. Specifically, as... Figure 4 , Figure 6 , Figure 9 and Figure 10 As shown, the battery box 1 has a battery compartment 12 for installing batteries 7. The battery compartment 12 is connected to the opening 2111. The cover 5 is provided on the battery box 1 and can be opened or covered. When the cover 5 is installed in the battery box 1, the cover 5 covers the opening 2111.

[0055] Understandably, the presence of the cover 5 protects the battery, reduces the entry of dust and dirt into the battery compartment 12, and extends the battery's lifespan; in addition, it prevents the battery from falling out of the battery compartment 12.

[0056] In one embodiment, the first end of the cover plate 5 is rotatably connected to the battery box 1 via a mounting shaft, and the second end of the cover plate 5 can be constrained onto the battery box 1. In this embodiment, as... Figure 4 , Figure 9 and Figure 10As shown, the first end of the cover plate 5 is provided with a mounting part 51 that can be detachably connected to the battery box 1. When the mounting part 51 is installed on the battery box 1, the mounting part 51 can rotate relative to the battery box 1, thereby driving the cover plate 5 to rotate to open and close the battery compartment 12. That is, the battery compartment 12 is opened or closed by rotating the cover plate 5. Specifically, the first end of the battery box 1 is provided with a mounting groove 13. The mounting groove 13 has an opening 130 on the side away from the second side wall 212, and a limiting plate 14 is provided on the side of the mounting groove 13 away from the second side wall 212 to cover part of the opening 130. The periphery of the opening 130 and the limiting plate 14 surround to form an opening 131 for the mounting part 51 to enter and exit the mounting groove 13. The mounting part 51 extends along the length direction of the cover plate 5 and can swing back and forth relative to the mounting groove 13 along the first direction A. When the cover plate 5 closes the battery compartment 12, the mounting part 51 abuts against the limiting plate 14.

[0057] Understandably, the limiting plate 14 restricts the upward movement of the mounting part 51. By adopting the aforementioned mounting method, the first end of the cover plate 5 can be installed on the battery box 1 more conveniently and quickly.

[0058] In addition, such as Figure 9 and Figure 10 As shown, the side of the limiting plate 14 facing the first clearance opening 50 is an arc-shaped convex surface 141 protruding in the direction of the first clearance opening 50, and the side of the first clearance opening 50 is an arc-shaped concave surface 501 that matches the arc-shaped convex surface 141.

[0059] Furthermore, the second end of the cover plate 5 is snapped into the corresponding position of the battery box 1 via a snap-fit ​​structure 6. Specifically, as shown... Figure 4 , Figure 9 and Figure 10 As shown, the snap-fit ​​structure 6 includes an elastic snap-fit ​​61 and a snap-fit ​​portion 151 that engages with the elastic snap-fit ​​61. In this embodiment, the elastic snap-fit ​​61 is disposed at the second end of the cover plate 5. Specifically, in order to better cover the opening 2111, the first end of the cover plate 5 has a first clearance opening 50 for the clearance limiting plate 14, and the mounting portion 51 is disposed within the first clearance opening 50. The second end of the cover plate 5 has a second clearance opening 52, and the elastic snap-fit ​​61 is disposed within the second clearance opening 52.

[0060] Additionally, the battery compartment 1 has an opening 15 for inserting a resilient latch 61. The side of the opening 15 extends inward to form the aforementioned latching portion 151. The resilient latch 61 has a latching slot 611 that engages with the latching portion 151. Alternatively, the latching portion 151 can be a latching interface that engages with the resilient latch 61, located at the second end of the battery compartment 1. This allows for easier and quicker installation of the second end of the cover 5 onto the battery compartment 1.

[0061] In addition, in order to fix the cover plate 5 to the battery box 1, the cover plate 5 can be fixed to the battery box 1 with screws.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
