Technical Field

[0001] The utility model relates to the technical field of construction auxiliary equipment, and more specifically, to a line-casting instrument. Background Art

[0002] A laser projector is an instrument that projects a visible laser. It is generally used to mark horizontal or plumb lines on a target surface. Due to its widespread use, laser projectors are often used in a variety of situations. However, the brightness of the light in existing laser projectors cannot be adjusted. Consequently, when the environment is dark, the light cannot be dimmed, resulting in wasted energy. Conversely, when the environment is bright, the light cannot be brightened, making the light unclear. Furthermore, existing laser projectors are inconvenient to operate, requiring manual operation of buttons on the instrument to operate it. Utility Model Content

[0003] The present invention overcomes two deficiencies in the prior art: (1) the line projection instrument cannot adjust the brightness of the light; (2) the light on the line projection instrument can only be adjusted by pressing a button on the line projection instrument, which is very troublesome to operate. The present invention provides a line projection instrument that can adjust the brightness of the light at any time, so that the appropriate light intensity can be set according to the strength of the environment, and has strong practical performance; in addition, the line projection instrument can be remotely controlled, making the operation of the line projection instrument more convenient.

Not only is it easy to operate, but the intensity of the light emitted by the projector can also be adjusted according to the actual environment. For example, when the environment is dark, the linear light spot can be dimmed through the external control device, which can save energy loss in the projector while ensuring clarity, thereby increasing the overall battery life of the projector. When the environment is brighter, the linear light spot can be brightened through the external control device, allowing the operator to see more clearly and facilitating construction operations.

When the external control device sends a command to the control component wirelessly, the control component receives and recognizes the command, thereby adjusting the light-emitting component, thereby adjusting the intensity of the light-emitting component, or controlling the light-emitting component to turn on and off. Therefore, by setting up the control component, the intensity of the light-emitting component can be directly controlled wirelessly from the outside, thereby achieving remote control of the intensity of the linear light spot.

[0010] Preferably, the control component is a wireless signal device, and the wireless signal device is connected to the housing via a wired connection.

[0011] By connecting an external wireless signal device, the structure of the line casting instrument itself can be reduced. When wireless remote control is required, the external signal device and the line casting instrument are connected, so that the line casting instrument without remote control can be set to a line casting instrument with remote control function.

[0012] Preferably, an interface is provided on the side wall of the shell, and the wireless signal device is connected to the interface.

[0022] Preferably, an arc-shaped avoidance groove is provided on the end surface of the vertical bracket facing the shell.

[0023] The provision of the arc-shaped avoidance groove facilitates the rotation of the shell and prevents the shell from interfering with the vertical bracket during rotation.

[0024] Compared with the existing technology, the beneficial effect of the present invention is that by providing a control component, the intensity of the light-emitting component can be directly controlled wirelessly from the outside, thereby realizing remote control of the intensity of the linear light spot. Not only is it easy to operate, but the intensity of the light emitted by the projector can also be adjusted according to the actual environment.

[0031] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0032] Example 1: Reference Figures 1 to 5As shown, a line projection instrument includes: a shell 1 and a light-emitting component capable of emitting a linear light spot and a control component arranged in the shell 1. The control component can adjust the light intensity of the light-emitting component.

[0033] The brightness of the light of the line projection instrument in the prior art cannot be adjusted, so when the environment is dark (for example, in an indoor environment), the brightness cannot be dimmed, which will result in a waste of electricity and a greater impact on the human eye when in use; and when the environment is bright (for example, in an outdoor environment), the brightness of the light cannot be brightened, making the light not very clear. In addition, the line projection instrument in the prior art is inconvenient to operate, and it is necessary to manually operate the buttons on the line projection instrument to operate the line projection instrument. For example, a decorator is decorating a house on one side of the room, and the line projection instrument is placed on the other side of the room. This requires the decorator to walk to one side of the line projection instrument to operate the line projection instrument, making the operation extremely inconvenient; in addition, during operation, the operator's hands may be dirty (such as cement or putty powder), causing damage to the line projection instrument during operation. Therefore, in this application, a control component and an external control device 2 are provided to remotely operate the light intensity of the line projection instrument.

[0034] In this application, a control component is provided, which can be wirelessly connected to an external control device 2, so that the control component can be operated remotely and wirelessly. When the external control device 2 sends a command to the control component wirelessly, the control component receives and recognizes the command, thereby adjusting the light-emitting component, thereby adjusting the intensity of the light-emitting component, or controlling the light-emitting component to be turned on and off. Therefore, by providing a control component, the intensity of the light-emitting component can be directly controlled wirelessly from the outside, thereby achieving remote control of the intensity of the linear light spot. Not only is it easy to operate, but the intensity of the light emitted by the projector can also be adjusted according to the actual environment. For example, when the environment is dark, the linear light spot can be dimmed through the external control device 2, which can save energy loss in the projector while ensuring clarity, thereby increasing the overall battery life of the projector. When the environment is bright, the linear light spot can be brightened through the external control device 2, allowing the operator to see more clearly and facilitating construction operations.

[0035] In addition, the control component in this application adopts PWM pulse width modulation, and controls the charging current by adjusting the PWM period and PWM duty cycle, thereby controlling the current in the light-emitting component and thus achieving stepless control of the light intensity.

[0036] Example 2: Reference Figures 1 to 5As shown, a line projection instrument includes: a shell 1 and a light-emitting component capable of emitting a linear light spot and a control component arranged in the shell 1. The control component can adjust the light intensity of the light-emitting component. The control component can be wirelessly connected to an external control device 2. The external control device 2 sends instructions to the control component in a wireless manner, thereby controlling the brightness of the light-emitting component.

[0037] The light-emitting component includes a first light-emitting component and a second light-emitting component, and the light-emitting component, the first light-emitting component and the second light-emitting component all belong to the existing technology; the light spot emitted by the first light-emitting component is a linear vertical light spot in the vertical direction, and the light spot emitted by the second light-emitting component is a linear horizontal light spot in the horizontal direction. The linear vertical light spot and the linear horizontal light spot intersect to form a cross-shaped light spot.

[0038] In this embodiment, the control component is disposed inside the housing 1 , and the control component is a Bluetooth control module disposed inside the housing 1 .

[0039] In one embodiment, the external control device 2 is a mobile phone, which is connected to the Bluetooth control module in the housing 1 via Bluetooth, so that the remote adjustment of the light of the projection meter can be achieved through the mobile phone. In addition, through the Bluetooth control module connection, Bluetooth has the characteristics of fast speed and stable data transmission, and the mobile phone can be connected to the projection meter via Bluetooth very conveniently and quickly. In addition, an APP dedicated to operating the projection meter can be set in the mobile phone, and different instructions can be issued to the projection meter through remote operation of the APP. For example, the intensity of the linear light spot emitted by the first light-emitting component and the second light-emitting component can be adjusted at the same time; or the intensity of the linear light spot emitted by the first light-emitting component or the second light-emitting component can be adjusted separately. For example, the light spot emitted by the first light-emitting component can be dimmed separately, and the light spot emitted by the second light-emitting component can be brightened, so as to achieve separate adjustment of the first light-emitting component and the second light-emitting component.

[0040] In one embodiment, the external control device 2 is a remote control. The remote control can be directly connected to the Bluetooth control module in the housing 1 via Bluetooth. Of course, the control component can also be set as an infrared receiver, and the remote control directly controls the line caster via infrared rays. Different instructions are issued to the line caster through the operation of the remote control. For example, the intensity of the linear light spot emitted by the first light-emitting component and the second light-emitting component can be adjusted at the same time; or the intensity of the linear light spot emitted by the first light-emitting component or the second light-emitting component can be adjusted separately. For example, the light spot emitted by the first light-emitting component can be dimmed separately, and the light spot emitted by the second light-emitting component can be brightened, so as to achieve separate adjustment of the first light-emitting component and the second light-emitting component.

[0041] In addition, the control component can also feed back the internal situation of the line casting instrument to the external control device 2 in a timely manner, for example, feeding back the power status of the line casting instrument to the remote control or mobile phone.

[0042] In this application, a control component is provided, which can be wirelessly connected to an external control device 2, so that the control component can be operated remotely and wirelessly. When the external control device 2 sends a command to the control component wirelessly, the control component receives and recognizes the command, thereby adjusting the light-emitting component, thereby adjusting the intensity of the light-emitting component, or controlling the light-emitting component to be turned on and off. Therefore, by providing a control component, the intensity of the light-emitting component can be directly controlled wirelessly from the outside, thereby achieving remote control of the intensity of the linear light spot. Not only is it easy to operate, but the intensity of the light emitted by the projector can also be adjusted according to the actual environment. For example, when the environment is dark, the linear light spot can be dimmed through the external control device 2, which can save energy loss in the projector while ensuring clarity, thereby increasing the overall battery life of the projector. When the environment is bright, the linear light spot can be brightened through the external control device 2, allowing the operator to see more clearly and facilitating construction operations.

[0043] In addition, the control component in this application adopts PWM pulse width modulation, and controls the charging current by adjusting the PWM period and PWM duty cycle, thereby controlling the current in the light-emitting component and thus achieving stepless control of the light intensity.

[0044] Example 3: Reference Figures 1 to 5 As shown, a line projection instrument includes: a shell 1 and a light-emitting component capable of emitting a linear light spot and a control component arranged in the shell 1. The control component can adjust the light intensity of the light-emitting component. The control component can be wirelessly connected to an external control device 2, and the external control device 2 sends instructions to the control component in a wireless manner.

[0045] The light-emitting component includes a first light-emitting component and a second light-emitting component, and the light-emitting component, the first light-emitting component and the second light-emitting component all belong to the existing technology; the light spot emitted by the first light-emitting component is a linear vertical light spot in the vertical direction, and the light spot emitted by the second light-emitting component is a linear horizontal light spot in the horizontal direction. The linear vertical light spot and the linear horizontal light spot intersect to form a cross-shaped light spot.

[0046] In this embodiment, the control component is a wireless signal transmitter externally connected to the line-casting instrument. This means the wireless signal transmitter and the line-casting instrument are two independent devices. The wireless signal transmitter is connected to the line-casting instrument via a wired connection. An interface 3 is provided on the side wall of the housing 1. The wireless signal transmitter is connected to this interface 3, allowing commands to be wirelessly transmitted from the external control device 2 to the external signal transmitter, which then controls and adjusts the light-emitting assembly.

[0047] External signal devices include but are not limited to Bluetooth controllers and infrared light wave controllers.

[0048] In one embodiment, the interface 3 is a type-C interface 3. Setting the type-C interface 3 can facilitate charging of the line thrower, and at the same time, the wireless signal transmitter can also be connected to the line thrower through the type-C interface 3, so that the structure of the line thrower is more concise.

[0049] In one embodiment, the external control device 2 is a mobile phone, which is connected to an external signal transmitter via Bluetooth, so that the light of the projection instrument can be remotely adjusted through the mobile phone. In addition, the external signal transmitter is connected via Bluetooth, which has the characteristics of fast speed and stable transmission. The mobile phone can also be very conveniently connected to the projection instrument via Bluetooth, making the operation more convenient. In addition, an APP dedicated to operating the projection instrument can be set in the mobile phone, so that different instructions can be issued to the projection instrument through the operation of the APP. For example, the intensity of the linear light spot emitted by the first light-emitting component and the second light-emitting component can be adjusted at the same time; or the intensity of the linear light spot emitted by the first light-emitting component or the second light-emitting component can be adjusted separately. For example, the light spot emitted by the first light-emitting component can be dimmed separately, and the light spot emitted by the second light-emitting component can be brightened, so as to achieve separate adjustment of the first light-emitting component and the second light-emitting component.

[0050] In one embodiment, the external control device 2 is a remote control. The remote control can be directly connected to the external signal transmitter via Bluetooth. Of course, the external control device 2 can also be set as an infrared receiver, and the remote control directly controls the line caster via infrared rays. By operating the remote control, different instructions can be issued to the line caster. For example, the intensity of the linear light spot emitted by the first light-emitting component and the second light-emitting component can be adjusted at the same time; or the intensity of the linear light spot emitted by the first light-emitting component or the second light-emitting component can be adjusted separately. For example, the light spot emitted by the first light-emitting component can be dimmed separately, and the light spot emitted by the second light-emitting component can be brightened, thereby realizing separate adjustment of the first light-emitting component and the second light-emitting component.

[0051] In addition, the external signal device can also feed back the internal situation of the line casting instrument to the external control device 2 in a timely manner, for example, feeding back the power level of the line casting instrument to the remote control or mobile phone.

[0052] In this application, a control component is provided, which can be wirelessly connected to an external control device 2, so that the control component can be operated remotely and wirelessly. When the external control device 2 sends a command to the control component wirelessly, the control component receives and recognizes the command, thereby adjusting the light-emitting component, thereby adjusting the intensity of the light-emitting component, or controlling the light-emitting component to be turned on and off. Therefore, by providing a control component, the intensity of the light-emitting component can be directly controlled wirelessly from the outside, thereby achieving remote control of the intensity of the linear light spot. Not only is it easy to operate, but the intensity of the light emitted by the projector can also be adjusted according to the actual environment.

When the environment is bright, the linear light spot can be brightened through the external control device 2, allowing the operator to see more clearly and facilitating construction operations.

[0053] In addition, the control component in this application adopts PWM pulse width modulation, and controls the charging current by adjusting the PWM period and PWM duty cycle, thereby controlling the current in the light-emitting component and thus achieving stepless control of the light intensity.

[0054] Example 4: This example is similar in structure to Example 1, Example 2, or Example 3, except that the line casting instrument in this application further includes a mounting bracket 4, which includes a horizontal bracket 41 and a vertical bracket 42. The vertical mounting bracket 4 is disposed at one end of the horizontal bracket 41.
