Description

Technical Field

[0001] This utility model relates to the field of laser instruments, and specifically to a frame for supporting a pendulum. Background Technology

[0002] Laser levels utilize laser beams to project laser lines onto walls and floors, significantly improving construction accuracy and efficiency. They are simple, efficient, and convenient to operate. Laser levels automatically level themselves through a built-in pendulum, which requires at least two pendulum axes connected to the frame to achieve automatic leveling.

[0003] To reduce size, existing laser instruments typically use a regular square frame to support the pendulum, with the pendulum body mounted below and the circuit board above. The pendulum shaft assembly is usually mounted on the same plane as the square frame. Since the pendulum shaft assembly generally has shafts in two directions and related assembly parts, the structure is complex. Especially in compact laser instruments, the space inside the square frame is small. When assembling the pendulum shaft inside the square frame, the direction of the pendulum shaft is blocked by the edge of the square frame, resulting in insufficient operation space for assembly. This makes it difficult to assemble bolts and nuts on the pendulum shaft. Utility Model Content

[0004] The purpose of this utility model is to provide a frame for supporting a pendulum, which solves the problem of inconvenient assembly of existing frames.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A frame for supporting a pendulum includes a frame and a pendulum axis assembly assembled within the frame. The pendulum axis assembly includes a first axis for assembly with the frame and a second axis for connection with the pendulum. The first axis and the second axis are cross-connected. The frame has at least one clearance space corresponding to the position of the second axis, so that the end of the second axis is exposed.

[0007] As a preferred embodiment of this utility model, the frame is provided with at least one pair of mounting parts for mounting the circuit board. In this embodiment, the mounting parts provided on the frame fix the circuit board to the top of the frame by fasteners.

[0008] As a preferred embodiment of this utility model, the mounting part extends upwards towards the frame, and the clearance space is set between the mounting parts. According to usage habits, the switch and circuit board of the laser instrument should preferably be set at the top. In order to make the structure of the laser instrument compact, this embodiment directly sets the mounting part on the frame for mounting the circuit board, and sets the clearance space between the mounting parts, which not only leaves operating space, but also helps to stabilize the structure and save materials.

[0009] As a preferred embodiment of the present invention, the frame is further provided with a bearing sleeve, and the first shaft is rotatably connected to the bearing sleeve. The bearing sleeve is used to install the first shaft and is assembled and connected to the first shaft through a bearing.

[0010] As a preferred embodiment of this utility model, a bearing is provided inside the bearing sleeve. The end of the first shaft is assembled with the bearing, and a nut is sleeved on the end surface of the first shaft. A flange is also provided on the inner side of the bearing sleeve. The nut is used to press the bearing onto the flange for fixation. This embodiment proposes an assembly method between the first shaft and the bearing sleeve, which is beneficial for the assembly of compact structures.

[0011] As a preferred embodiment of this utility model, a support part is further provided below the frame, wherein a plurality of docking holes are provided below the frame, and the support part is used to assemble and connect with the docking holes to support the frame. This embodiment forms a complete frame by providing a support part, which is convenient for installation inside the laser instrument housing.

[0012] As a preferred embodiment of this utility model, the mating hole has a stepped inner diameter, the support part penetrates into the large end of the mating hole, and the top end of the support part has a threaded groove. The small end of the mating hole is used to install a fixing bolt to connect with the support part, which facilitates the connection between the support part and the frame.

[0013] As a preferred embodiment of this utility model, the first shaft and the second shaft are perpendicular to each other and their axes intersect. This solution sets the cross shaft in this way, which saves the space occupied by the swing shaft and facilitates the miniaturization of the structure.

[0014] The beneficial effects of this utility model are as follows: This solution provides clearance space on the frame to allow space for the connection between the second axis and the pendulum body, which facilitates the tightening of bolts / screws that may occur during the connection and debugging of the pendulum body. This frame structure is conducive to setting a cross-shaped pendulum axis and can be completely set inside the frame, which is conducive to the development of miniaturized structure.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1-5 As shown, a frame for supporting a pendulum includes a frame 1 and a pendulum shaft assembly 2 assembled within the frame 1. The pendulum shaft assembly 2 includes a first shaft 21 for assembly with the frame 1 and a second shaft 22 for connection with the pendulum. The first shaft 21 and the second shaft 22 are cross-connected. At least one clearance space 103 is provided on the frame 1 corresponding to the position of the second shaft 22, so that the end of the second shaft 22 is exposed.

[0024] This embodiment provides a clearance space 103 on the frame to allow space for the connection between the second shaft 22 and the pendulum body, facilitating the tightening of bolts / screws. During implementation, the clearance space 103 can be formed by a curved archway to make the frame 1 continuous. The pendulum shaft assembly 2 is installed inside the frame 1. Then, when assembling the pendulum body, the bolts / screws that may be used on the second shaft 21 are tightened through the position of the clearance space 103.

[0025] Preferably, the frame 1 is provided with at least one pair of mounting portions 102 for mounting the circuit board 4. The mounting portions 102 provided on the frame 1 are used to fix the circuit board 4 on the frame 1 by means of fasteners 5.

[0026] Please see Figure 2 As a further optimization of this embodiment, the mounting part 102 extends upwards towards the frame 1, and the clearance space 103 is disposed between the mounting parts 102. According to usage habits, the circuit board 4 should preferably have the laser device at the top. In order to make the laser device structure compact, this solution directly sets the mounting part 102 on the frame 1 for mounting the circuit board 4, and the clearance space 103 is disposed between the mounting parts 102, which not only leaves operating space, but also helps to stabilize the structure and save materials.

[0027] Preferably, multiple mounting parts 102 can be provided, extending from the top of the frame 1. Only one pair of mounting parts 102 needs to be provided at the edge of the frame 1 where a clearance space 103 needs to be provided. Alternatively, two clearance spaces 103 can be provided, with corresponding clearance spaces 103 provided at both ends of the second shaft 22.

[0028] In another embodiment, the frame 1 is also provided with a bearing sleeve 101, and the first shaft 21 is rotatably connected to the bearing sleeve 101. The bearing sleeve 101 is used to install the first shaft 21, and it is assembled and connected to the first shaft 21 through a bearing 23.

[0029] Specifically, a bearing 23 is provided inside the bearing sleeve 101. The end of the first shaft 21 is assembled with the bearing 23, and a nut 24 is sleeved on the end surface of the first shaft 21. A flange 105 is also provided inside the bearing sleeve 101. The nut 24 is used to press the bearing 23 onto the flange 105 for fixation. This method is conducive to the assembly of compact structures.

[0030] Preferably, in order to make the frame complete, this solution provides a support part 3 below the frame 1. The frame 1 has several docking holes 104 below it. The support part 3 is used to assemble and connect with the docking holes 104 to support the frame 1. By setting the support part 3, a complete frame 1 is formed, which is convenient to install inside the laser instrument housing.

[0031] Specifically, the mating hole 104 has a stepped inner diameter, the support part 3 penetrates into the large end of the mating hole 104, and the top end of the support part 3 has a threaded groove. The small end of the mating hole 104 is used to install a fixing bolt to connect with the support part 3, so as to facilitate the connection between the support part 3 and the frame 1.

[0032] As an alternative implementation, the support 3 can also extend outward from the side of the frame 1 and ultimately be used to fix and connect with the housing of the laser device to support the frame 1.

[0033] As a preferred embodiment, to achieve a compact structure, the first axis 21 and the second axis 22 are further arranged to be perpendicular to each other and their axes intersect. This arrangement of the cross axis saves space occupied by the pendulum axis and facilitates structural miniaturization. For details, please refer to [link to relevant documentation]. Figure 5 A bushing is provided on the second shaft 22, through which the first shaft 21 passes. After the through connection, a positioning pin is provided in the radial direction to fix the junction of the first shaft 21 and the second shaft 22.

[0034] Assemble the swing body with the second axis 22, tighten the bolts / screws through the clearance space 103, then install the circuit board 4 on the mounting part 102, and finally assemble and connect the frame 1 with the support part 3.

[0035] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
