[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] such as Figures 1 to 9As shown, the utility model is a kind of laser leveler side sliding switch waterproof mechanism, it is mainly by seat (1), side sliding switch (2), silica gel pressing plate (3), switch support (5) and button waterproof silica gel piece (6) is formed, it needs to be stated, the seat (1) described and demonstrated in the utility model is the base of laser leveler, not the complete structure of laser leveler, because the technology of the utility model is mainly in the switch of base, its structural relationship is after being assembled with switch support (5) It can be linked to realize work, so only describe base also meet the structure and principle required to be shown.

[0026] The assembly structural relationship of the utility model is as follows:

[0027] The seat (1) is provided with window (10) for the inside and outside linkage of side sliding switch (2) and switch support (5) movable assembly, wherein switch support (5) is clamped in the inner side of seat (1), located in the rear of window (10);Silica gel pressing plate (3) and button waterproof silica gel piece (6) are arranged between side sliding switch (2) and switch support (5);The silica gel pressing plate (3) is connected with the button waterproof silica gel piece (6) clamped in window (10) by locking screw (4), and the silica gel pressing plate (3) and button waterproof silica gel piece (6) are also based on locking screw (4) Reinforced installation is set in window (10).

[0028] Among them, the outer edge of window (10) is formed with positioning convex part (9) and screw hole, the positioning convex part (9) is for the embedding fixing of button waterproof silica gel piece (6), such structure setting not only can make button waterproof silica gel piece (6) quickly positioning, also can not produce shaking displacement when locking screw (4) is screwed, make assembly work more smoothly, more importantly, positioning convex part (9) is formed on the convex edge of window (10), it can be more closely with button waterproof silica gel piece (6) after locking screw (4) is screwed, avoid liquid to seep into the gap between them.

[0029] To achieve the active assembly of internal and external linkage, the side sliding switch (2) is integrally formed with a locking guide post (20), the silicone pressure plate (3) is provided with a sliding slot (30) for the locking guide post (20) to pass through, the waterproof silicone button part (6) is designed with a linkage hole (60) for the locking guide post (20) to be locked, and the switch bracket (5) is formed with a screw hole (50) for the locking guide post (20) to be inserted. Specifically, after the side sliding switch (2) passes through the sliding slot (30) of the silicone pressure plate (3), it is connected to the linkage hole (60) with an interference fit, and the length of its extended part can also reach the screw hole (50) of the switch bracket (5) for insertion assembly. Therefore, the installation position of the side sliding switch (2) is fixed by the linkage hole (60) and the screw hole (50). It can be further explained that the diameter of the sliding slot (30) is larger than the maximum diameter of the locking guide post (20). Since the sliding slot (30) is the travel slot for the left and right sliding of the side sliding switch (2), it is necessary to ensure the smooth sliding of the side sliding switch (2). In addition, it is worth mentioning that the switch bracket (5) is also threadedly connected to the locking guide post (20) inserted in its screw hole (50) by a locking screw (4) to reinforce the installation. This prevents the side sliding switch (2) from coming loose from the screw hole (50) and the linkage hole (60) when the side sliding switch (2) is moved left and right for a long time, which would cause abnormal use or no longer be effective in waterproofing.

[0030] Regarding the waterproof silicone button component (6), it is molded with an auxiliary groove (61) to align and position the protrusion (9), thereby achieving embedded fixation. More importantly, it is designed and molded with a V-shaped structure based on flexible silicone material. The V-shaped structure is molded in both vertical and horizontal directions, presenting a bidirectional wave-shaped structure design. The first flexible surface (62), the second flexible surface (63), and the third flexible surface (64) are horizontal upward V-shaped structures, while the fourth flexible surface (65) and the fifth flexible surface (66) constitute a vertical V-shaped structure. Such a structural design has significant positive effects. For example, the distribution of the V-shaped structure in the horizontal direction is two on the left, which can provide tensile deformation, and three on the right, which can provide compressive deformation. The V-shaped structure in the vertical direction is to limit the height to the maximum, which facilitates the tensile deformation with the maximum stroke. At the same time, it can prevent the edges from falling off during tensile deformation, allowing the waterproof silicone button component (6) to be tightly installed inside the window (10) without gaps, avoiding water vapor or liquid seepage. Furthermore, through design and research, the waterproof silicone part (6) for the button, with a thickness of 0.3 mm and a hardness of 30 degrees, can minimize the impact of the material's own elasticity on the movement of the sliding switch, and at the same time achieve more than 5,000 reciprocating switching movements without deformation or damage.

[0031] The side sliding switch (2) is formed with a toggle protrusion and anti-slip texture to enhance the user experience and practicality.

[0032] The silicone pressure plate (3) is also set in the window (10) by interference fit based on the elastic deformation characteristics.

[0033] This utility model can be divided into internal waterproofing and external waterproofing to achieve the research and development purpose. The external waterproofing is that the silicone pressure plate (3) and the button waterproof silicone part (6) are tightly attached to each other with the cooperation of the locking screw (4), and both are interference fit assembly in the window (10). In addition, the sliding groove hole (30) on the silicone pressure plate (3) is opened in a position that is biased towards the center and has a certain height, so it can be used for external waterproofing to prevent liquid or water vapor from seeping in here. The internal waterproofing is based on the connection between the switch bracket (5) and the side sliding switch (2). The side sliding switch (2) and the linkage hole (60) of the button waterproof silicone part (6) are fitted with an interference fit, which can be regarded as the first layer of internal waterproofing design. The side sliding switch (2) passing through the linkage hole (60) is also inserted into the screw hole (50) of the switch bracket (5) and connected with a tightening screw (4). This can be regarded as the second layer of internal waterproofing design. With this design, even if liquid or water vapor enters between the silicone pressure plate (3) and the button waterproof silicone part (6) through the sliding groove hole (30), it is difficult to seep out at the linkage hole (60) which is an interference fit. Even if it can seep out at the linkage hole (60), the linkage hole (60) is still tightly attached to and fitted with the switch bracket (5), and the switch bracket (5) is screwed with a locking screw (4) for pressure reinforcement, which is the final waterproofing. Therefore, this utility model can achieve a waterproofing effect at the switch.

[0034] This utility model provides a waterproof mechanism for a side-sliding switch applied to a laser level. This structure enables the side-sliding switch (2) to work smoothly in left and right movements while also being waterproof, and does not affect the feel and function of the button when sliding.
