Description

Technical Field

[0001] This utility model relates to the field of measuring equipment technology, specifically a laser leveling instrument. Background Technology

[0002] A laser leveling instrument is a measuring instrument that integrates laser emission and automatic leveling functions. It is widely used in construction, decoration, engineering and other fields to quickly and accurately project horizontal or vertical laser lines as construction baselines.

[0003] A search revealed a Chinese patent (CN216081478U) disclosing an automatic laser level, comprising a level body. The level body includes an outer protective shell and an inner protective shell, arranged sequentially from the outside in. A groove is formed at the center of the bottom of the inner wall of the outer protective shell. A sliding rod is fixedly connected inside the groove. Several symmetrical sliding blocks are slidably connected to the outer surface of the sliding rod and the inside of the groove. A spring is fixedly connected to the top of one side of each sliding block. Several symmetrical connecting blocks are fixedly connected to the bottom of the inner protective shell. Symmetrical connecting rods are hinged to both sides inside each connecting block. This design effectively weakens and mitigates vibration and impact forces, protecting the device and reducing its sway. It improves the laser level's performance in resisting vibration and impact, enhancing its protective stability and facilitating its use.

[0004] However, in actual use, the above-mentioned patents and existing patents mainly address the issue of shockproof housings, which mostly use rotary switches. Since laser leveling devices are usually used in construction and decoration projects, the working environment may be subject to vibration or accidental contact, causing the knob to rotate unexpectedly and thus changing the opening and closing state of the device. Therefore, we propose a laser leveling device. Utility Model Content

[0005] The technical problem to be solved by this application is that the above-mentioned patents and existing patents mainly address the problem of shockproof housings, which mostly use rotary switches. Since laser leveling instruments are usually used in construction and decoration projects, the working environment may be subject to vibration or accidental contact, causing the knob to rotate unexpectedly, thereby changing the opening and closing state of the device.

[0006] To address the aforementioned technical problems, this application provides a laser slewing device, comprising a slewing device body and a rotary switch rotatably connected to the outside of the slewing device body. One end of the rotary switch is fitted with a rotating cylinder, and a first motor with its output end connected to the rotating cylinder is fitted on one side of the slewing device body. An electric telescopic rod is installed inside the rotating cylinder, and a trapezoidal block is connected to the output end of the electric telescopic rod. The top and bottom of the trapezoidal block slidably abut against wedge blocks that are slidably engaged with the slewing device body. The two wedge blocks are connected by a limiting component.

[0007] In some embodiments, the outer side of the pacing instrument body is provided with a groove adapted to the size of the rotating drum and the first motor, and the top and bottom of the groove are provided with slots adapted to the size of the wedge block.

[0008] In some embodiments, the top and bottom wedges are provided with grooves for placing a limiting component on their adjacent sides. The limiting component includes an outer fixing frame installed at the bottom of the top wedge and an inner fixing frame installed at the top of the bottom wedge. Each of the outer and inner fixing frames has a support rod that is slidably connected to it on one side. A spring is connected between the top and bottom support rods.

[0009] In some embodiments, the upper end of the pacifier body is provided with laser windows in both horizontal and vertical directions. Two second motors in both horizontal and vertical directions are installed inside the two laser windows respectively. The output end of the second motor is connected to a rotating rod. A laser emitting module is installed at the end of the rotating rod away from the second motor. A glass plate located outside the laser emitting module is installed in the laser window.

[0010] In some embodiments, a placement slot is provided at the lower end of the instrument body, in which a battery is placed. A maintenance door covering the placement slot is hinged to the lower end of the instrument body. An external battery pack interface is installed on the maintenance door. A power management circuit is installed on the top of the placement slot.

[0011] In some embodiments, the inside of the instrument body is further provided with a wireless communication module, and the outside of the instrument body is further provided with a wireless receiver.

[0012] This utility model has at least the following beneficial effects:

[0013] An electric telescopic rod is installed to push the trapezoidal block to slide, so that the two wedge blocks unfold and fix the body of the leveling instrument, forming a mechanical lock on the knob switch. This locking method can effectively prevent the knob switch from rotating and changing the open or closed state of the equipment due to vibration or accidental contact. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1-3 This utility model provides a technical solution: a laser slewing device, including a slewing device body 1 and a rotary switch 2 rotatably connected to the outside of the slewing device body 1. A rotating cylinder 3 is installed at one end of the rotary switch 2. A first motor 4 with its output end connected to the rotating cylinder 3 is installed on one side of the slewing device body 1. An electric telescopic rod 5 is installed inside the rotating cylinder 3. A trapezoidal block 6 is connected to the output end of the electric telescopic rod 5. The top and bottom of the trapezoidal block 6 slide against wedge blocks 7 that slide and engage with the slewing device body 1. The two wedge blocks 7 are connected by a limiting component 8.

[0022] Furthermore, the rotary switch 2 is electrically connected to the power supply of the caliper body 1. The rotating cylinder 3 connects the rotary switch 2 and the first motor 4, transmitting the rotational force of the first motor 4 to the rotary switch 2. The rotary switch 2 controls the opening and closing state of the caliper body 1. The output end of the electric telescopic rod 5 is connected to the trapezoidal block 6, converting the power of the first motor 4 into the linear motion of the trapezoidal block 6. Through the extension and retraction of the electric telescopic rod 5, the trapezoidal block 6 is driven to slide inside the rotating cylinder 3, thereby affecting the state of the wedge block 7 and securing the caliper body 1 to prevent accidental activation. The outer side of the caliper body 1 is provided with a groove 101 that matches the size of the rotating cylinder 3 and the first motor 4. The top and bottom of the groove 101 are provided with slots 102 that match the size of the wedge block 7. The groove 101, whose size matches the rotating cylinder 3 and the first motor 4, provides installation space for the rotating cylinder 3 and the first motor 4.

[0023] The top and bottom wedge blocks 7 are provided with grooves 701 for placing the limiting component 8 on their adjacent sides. The limiting component 8 includes an outer fixing frame 801 installed at the bottom of the top wedge block 7 and an inner fixing frame 802 installed at the top of the bottom wedge block 7. A support rod 803 is provided on one side of the outer fixing frame 801 and the inner fixing frame 802 and is slidably connected to each other. A spring 804 is connected between the top and bottom support rods 803.

[0024] Furthermore, the design of the slide groove 701 is used to place the limiting component 8. Through the cooperation of the outer fixing frame 801 and the inner fixing frame 802, the support rod 803 is restricted within a fixed range during the sliding process, preventing it from deviating from the track and ensuring that the support rod 803 will not fall off under extreme conditions (such as vibration or external impact), thus ensuring the stability and reliability of the equipment. The support rod 803 increases the installation space, ensuring that the spring 804 can be compactly installed in the limited space.

[0025] Example 2: Based on Example 1, as follows Figure 4 As shown, the upper end of the balance instrument body 1 is provided with laser windows 103 in two directions, one horizontal and one vertical. Two second motors 9 in two directions, one horizontal and one vertical, are installed inside the two laser windows 103 respectively. The output end of the second motor 9 is connected to a rotating rod 10. A laser emitting module 11 is installed at the end of the rotating rod 10 away from the second motor 9. A glass 12 located outside the laser emitting module 11 is installed in the laser window 103. A guide rail 13 is symmetrically installed inside the laser window 103 and attached to the inner side of the glass 12. The inner side of the guide rail 13 is slidably connected to the outer side of the laser emitting module 11.

[0026] The second motor 9 drives the rotating rod 10 to rotate the laser emitting module 11, thereby adjusting the horizontal and vertical angles of the laser to ensure accurate positioning and improve measurement accuracy. The inner side of the guide rail 13 is slidably connected to the outer side of the laser emitting module 11. This connection method can increase the stability of the rotation of the laser emitting module 11 and ensure that the laser emitting module 11 does not deviate from the predetermined trajectory during rotation.

[0027] Example 3: Based on Example 2, such as Figure 5 As shown, the lower end of the instrument body 1 is provided with a placement slot 104, in which a battery 14 is placed. The lower end of the instrument body 1 is hinged with a maintenance door 15 covering the placement slot 104. An external battery pack interface 16 is installed on the maintenance door 15. A power management circuit 17 is installed on the top of the placement slot 104.

[0028] In practical implementation, battery 14 is a high-energy-density lithium battery. The power management circuit 17 shortens charging time and reduces downtime. The external battery pack is directly powered through the external battery pack interface 16. During long-term outdoor operations (such as large-scale construction), the external battery pack can serve as a backup power source, preventing task interruption due to the depletion of the internal battery. The power management circuit 17 is electrically connected to the laser emission module 11, battery 14, and external battery pack interface 16. It can automatically switch power sources according to the power requirements of each component and the battery status, prioritizing the use of the external battery pack. The internal battery 14 serves as a supplementary or emergency power source. When the internal battery charge is lower than... At 10%, the power management circuit 17 automatically reduces the laser emission power, extends the battery life, and prompts the user to replace the battery. The maintenance door 15 facilitates the replacement of the battery 14 in the placement slot 104 of the instrument body 1. It should be noted that in actual use, in order to prevent the battery 14 from falling out due to accidental opening of the maintenance door 15 during normal use, a key lock connected to the instrument body 1 needs to be installed on the maintenance door 15. A rubber sealing ring is set at the contact point between the maintenance door 15 and the placement slot 104. This rubber sealing ring should have good sealing performance to effectively prevent rainwater and dust from entering and ensure the safety of the battery 14. The external battery pack interface 16 is equipped with common interfaces according to usage needs, compatible with mainstream power banks or car chargers, improving power supply flexibility.

[0029] Example 4: Based on Example 3, such as Figure 5As shown, the internal structure of the caliper body 1 is equipped with a wireless communication module 18, and the external structure of the caliper body 1 is equipped with a wireless receiver 19. The wireless communication module 18 and the wireless receiver 19 are electrically connected to the first motor 4, the electric telescopic rod 5, the second motor 9, the laser emitting module 11, and the external remote control. The wireless communication module 18 receives the instructions sent by the external remote control and transmits them to the corresponding components (such as the first motor 4, the electric telescopic rod 5, etc.), thereby realizing remote control of the caliper body 1. This allows the caliper body 1 to receive remote control instructions from external devices. Users do not need to directly contact the caliper body 1 to send start and stop instructions through the remote control or other wireless devices to realize the static start and stop operation of the caliper. This remote control method improves the convenience and flexibility of operation, especially in situations where it is necessary to keep the caliper stable and stationary, such as precision measurement or long-term monitoring tasks.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
