Description

Technical Field

[0001] This utility model relates to the technical field of level mounting devices, and in particular to a level receiver with a folding support device. Background Technology

[0002] A laser level, also known as a laser ink line indicator, projects a laser line onto the surface of an object using the principle of light reflection, serving as a reference line. Users observe this laser reference line to perform indoor and outdoor construction, work, and leveling. The product is widely used in engineering construction and home decoration. The level receiver is used when the laser reference line cannot be observed with the naked eye in outdoor or well-lit working environments. In this case, the laser line emitted by the level emits pulse signals, which the user receives through the receiver instead of visually locating the laser reference line.

[0003] Currently, most level receivers on the market are used by hand or fixed to additional connecting accessories. They cannot be placed on the ground alone for laser line positioning or have low work efficiency. Once the receiver is bumped, the user's work efficiency will decrease. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A level receiver with a folding support device includes a receiver body, which includes an upper shell and a lower shell. The upper shell and the lower shell are fixedly connected and enclose a cavity for accommodating internal components. A removable battery cover is provided on the side of the lower shell away from the upper shell. A foldable support plate is provided on the side of the battery cover away from the lower shell. Connecting shafts are provided at both ends of the top of the battery cover. A connecting part corresponding to the connecting shaft is provided at the top of the support plate. The connecting part is provided with a mounting hole adapted to the connecting shaft. The support plate is rotatable around the connecting shaft.

[0012] Beneficial effects:

[0013] The level receiver in this invention is equipped with foldable support feet. When the receiver is placed on the ground, the receiver changes from relying on two-point planar contact to three-point contact, thereby increasing the stability of the receiver and improving the accuracy of the receiving operation.

[0019] In the description of this embodiment, it should be noted that the terms "upper," "lower," "inner," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, unless otherwise expressly specified and limited, the terms "installation," "connection," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0020] In addition, unless otherwise specified, the components used in the following embodiments are all existing components, and their corresponding connection methods can also be achieved through conventional technical means, which will not be described in detail in this application. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example

[0022] This embodiment provides a level receiver with a folding support device, such as Figures 1 to 4 As shown, the receiver includes a main body. The main body comprises an upper housing 1 and a lower housing 2, which are fixedly connected and enclose a cavity for accommodating internal components. A detachable battery cover 3 is mounted on the side of the lower housing 2 away from the upper housing 1. The battery cover 3 is connected to the lower housing 2 via a snap-fit ​​mechanism, consistent with existing detachable battery covers. A foldable support plate 4 is provided on the side of the battery cover 3 away from the lower housing 2. Connecting shafts 31 are fixedly mounted at both ends of the top of the battery cover 3. The top of the support plate 4 has two connecting parts 41 corresponding to the connecting shafts 31, each with a mounting hole 42 adapted to the connecting shaft 31. The two connecting parts 41 are arranged on opposite sides of the top of the battery cover 3, and the distance between the two connecting parts 41 is slightly smaller than the distance between the two ends of the connecting shaft 31. Because the support plate 4 is made of elastic plastic, slight deformation can embed the connecting shafts 31 into the corresponding mounting holes 42 of the two connecting parts 41, achieving a rotatable connection between the support plate 4 and the battery cover 3. In use, the support plate 4 can rotate flexibly around the connecting shaft 31. Rotating it towards the battery cover 3 will allow it to be stored, while rotating it away from the battery cover 3 will allow it to be unfolded. After the support plate 4 is unfolded, two fulcrums are formed at the bottom ends of the receiver body, and the unfolded support plate 4 forms a third fulcrum. The three components work together to ensure that the receiver body can be stably placed on the work site.

[0023] It should be noted that, in this embodiment, the receiving cavity of the level receiver body contains conventional components such as a silicon photodiode, a signal processing circuit, a display screen, and a power supply module. The silicon photodiode receives the laser pulse signal emitted by the level, and the signal processing circuit converts the optical signal into an electrical signal to drive the display screen to show the position of the laser reference line. The connection relationships and working principles of these internal components are common knowledge in the art and will not be elaborated here.

[0024] Preferably, the battery cover 3 is provided with fixing buckles 32 on both sides. The fixing buckles 32 are elastic plastic structures, and the support plate 4 is provided with fixing slots 43 on both sides corresponding to the fixing buckles 32. When the support plate 4 is rotated towards the battery cover 3 to the storage position, the fixing buckles 32 can lock the edge of the fixing slots 43 through their own elastic deformation, thereby achieving mechanical locking of the support plate 4 and completing the storage.

[0025] Preferably, the battery cover 3 is further provided with a positioning groove 33, and the support plate 4 is provided with a corresponding positioning protrusion 44. When the support plate 4 is folded and stored, the positioning protrusion 44 can be embedded in the positioning groove 33, and the support plate 4 and the battery cover 3 are precisely fitted and positioned through the concave-convex cooperation, effectively preventing the folded support plate 4 from being accidentally unfolded due to shaking or collision.

[0026] Although the embodiments of this utility model have been described in the specification, these embodiments are merely illustrative and should not limit the scope of protection of this utility model. Various omissions, substitutions, and modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
