Description

Technical Field

[0001] This utility model belongs to the field of humidity monitoring technology, specifically relating to a handheld humidity monitoring device for cleanrooms. Background Technology

[0002] A cleanroom is a closed environment that controls parameters such as air pollution levels, temperature, humidity, airflow speed, and airflow distribution. It aims to maintain a high level of air purity to facilitate production, inspection, and experimental processes that are sensitive to particulate matter.

[0003] Cleanrooms are widely used in semiconductor manufacturing, biopharmaceuticals, medical devices, microelectronics, optoelectronics, precision instruments, food processing, and other fields. Monitoring humidity is crucial in cleanrooms because it significantly impacts internal air quality and production process control.

[0004] The utility model patent with patent authorization announcement number CN220508126U discloses a handheld multi-functional environmental monitor that integrates a hydrogen peroxide concentration sensor, a temperature and humidity sensor, a control unit, a display unit, a battery unit, and an operation unit into a small housing.

[0005] However, existing handheld humidity monitoring devices for cleanrooms also have certain shortcomings. Most of the existing handheld humidity monitoring devices for cleanrooms adopt an integrated design and are intended for handheld use by operators. Due to the complexity of the internal environment of the cleanroom, it is difficult for operators to monitor the humidity at different heights inside the cleanroom. Summary of the Invention

[0006] The purpose of this invention is to provide a handheld humidity monitoring device for cleanrooms, which solves the problem that existing handheld humidity monitoring devices for cleanrooms are mostly designed as integrated units, intended for handheld use by operators. Due to the complexity of the cleanroom environment, it is difficult for operators to monitor humidity at different heights within the cleanroom.

[0007] To achieve the above objectives, this utility model provides a handheld humidity monitoring device for cleanrooms, comprising a support cylinder, a handle fixedly connected to the lower end of the support cylinder, a support frame slidably connected to the inner wall of the support cylinder, a support block fixedly connected to the upper horizontal part of the support frame, a monitor contacting the left end of the support block, a nut fixedly connected to the right end of the support block, a screw threadedly connected to the inside of the nut, a guide rod fixedly connected to the right end of the support block, a locking block slidably sleeved on the outer side of the guide rod, the locking block slidably connected to the screw rod, a spring provided on the outer side of the guide rod, and a lifting mechanism jointly provided on the support cylinder and the support frame.

[0008] The principle of this utility model is as follows: by pulling the locking block to the right, the locking block moves along the surface of the guide rod, and the spring deforms. When the locking block contacts the limiting plate of the guide rod, the spring stops deforming, which can push the monitor to contact the support block and allow the screw to pass through the support block, so that the screw contacts the nut. Then, the monitor is pushed to rotate, which drives the screw to rotate. With the threaded connection, the screw can be fixed and the monitor can be installed. The locking block is then released to allow the spring to return to its original deformation, so that the locking block can be pulled to insert into the screw, limiting the screw and preventing the screw and monitor from vibrating and loosening.

[0009] The motor drives the output shaft to rotate, which in turn drives the gears. In this meshing relationship, the gears push the gear plate to move, causing the support frame to slide along the inner wall of the support cylinder. This, in turn, moves the support block, ultimately moving the monitor to adjust its position for subsequent monitoring. When the motor drives the output shaft to rotate, it also drives the fixed disk to rotate. Under the pressure of the inner wall of the locking hole, the locking ball moves, pushing the guide block to slide along the inner wall of the fixed disk. Spring two deforms, causing the locking ball to disengage from the locking hole. Under the action of force, the locking ball slides along the inner wall of the mounting cylinder. When the locking ball slides into the next locking hole, spring two returns to its original deformation, pushing the locking ball back into the locking hole, limiting the fixed disk, and thus limiting the rotation of the motor output shaft, ultimately positioning the monitor for use.

[0010] The beneficial effects of this utility model are as follows: This solution, through the setting of screw, nut and other structures, allows for the installation and use of the monitor. With the structure of guide rod, spring one, and locking block, the screw can be limited to avoid the problem of screw vibration and loosening, so as to ensure the long-term stability of the monitor installation. With the setting of handle, support cylinder and other structures, the monitor can be used for handheld monitoring. With the structure of motor, gear, toothed plate and other structures, the monitor can be driven to move and its position can be adjusted to improve the monitoring effect. With the structure of locking hole, locking ball, spring two and other structures, the output shaft of the motor can be limited to rotate, thereby positioning the monitor for use.

[0011] Furthermore, the screw is movably connected to the support block and fixedly connected to the monitor. The monitor can be fixedly installed and used by means of the screw.

[0012] Furthermore, one end of the spring is welded to the locking block, and the other end of the spring is welded to the support block. The locking block can be connected and used through the setting of the spring.

[0013] Furthermore, a limiting plate is fixedly connected to the right end of the guide rod. The limiting plate is made of rubber, and the movement of the locking block can be limited by the setting of the limiting plate.

[0014] Furthermore, the lifting mechanism includes a toothed plate. The toothed plate is fixedly connected to the lower horizontal part of the support frame. The toothed plate is slidably connected to the support cylinder. An installation cylinder is fixedly connected to the left side of the support cylinder. A motor is fixedly installed on the inner left side wall of the installation cylinder. The output shaft of the motor is rotatably connected to the installation cylinder. The inner wall of the installation cylinder has a locking hole. A fixed plate is fixedly sleeved on the outer side of the output shaft of the motor. The fixed plate is rotatably connected to the installation cylinder. A guide block is slidably connected to the inner wall of the fixed plate. A locking ball is fixedly connected to the upper end of the guide block. The locking ball is slidably connected to the locking hole. A second spring is welded to the lower end of the guide block. The other end of the second spring is welded to the fixed plate. Through the setting of the motor, toothed plate, and other structures, the monitor can be driven to move and the position of the monitor can be adjusted. Under the action of the locking hole, locking ball, and other structures, the fixed plate can be rotated and limited, thereby positioning the monitor for use.

[0015] Furthermore, a gear is fixedly sleeved on the outside of the output shaft of the motor. The gear meshes with the gear plate, and through the meshing relationship, the gear can drive the gear plate to move when it rotates.

[0016] Furthermore, multiple locking holes are provided, and these multiple locking holes are arranged in a circular array on the mounting cylinder. The locking holes facilitate the use of locking balls for engagement. Attached Figure Description

Detailed Implementation

[0024] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this embodiment provides a handheld humidity monitoring device for a cleanroom, including a support cylinder 1, a handle 2 fixedly connected to the lower end of the support cylinder 1, a support frame 3 slidably connected to the inner wall of the support cylinder 1, a support block 4 fixedly connected to the upper horizontal part of the support frame 3, a monitor 5 contacting the left end of the support block 4, a nut 6 fixedly connected to the right end of the support block 4, a screw rod 7 threadedly connected inside the nut 6, a guide rod 8 fixedly connected to the right end of the support block 4, a locking block 9 slidably sleeved on the outer side of the guide rod 8, the locking block 9 slidably connected to the screw rod 7, a spring 10 provided on the outer side of the guide rod 8, and a lifting mechanism 11 jointly provided on the support cylinder 1 and the support frame 3.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, screw 7 is movably connected to support block 4, and screw 7 is fixedly connected to monitor 5. The monitor 5 can be fixedly installed and used through the setting of screw 7. One end of spring 10 is welded to the locking block 9, and the other end of spring 10 is welded to support block 4. The locking block 9 can be connected and used through the setting of spring 10. The right end of guide rod 8 is fixedly connected to a limit plate. The limit plate is made of rubber. The locking block 9 can be moved and limited through the setting of the limit plate.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, the lifting mechanism 11 includes a toothed plate 111. The toothed plate 111 is fixedly connected to the lower horizontal part of the support frame 3. The toothed plate 111 is slidably connected to the support cylinder 1. The left side of the support cylinder 1 is fixedly connected to the mounting cylinder 1. The inner left side wall of the mounting cylinder 112 is fixedly mounted with a motor 113. The output shaft of the motor 113 is rotatably connected to the mounting cylinder 112 and the support cylinder 1. The inner side wall of the mounting cylinder 112 has a locking hole 115. A fixing plate 116 is fixedly sleeved on the outer side of the output shaft of the motor 113. The fixing plate 116 rotates with the mounting cylinder 112. The inner wall of the fixed disk 116 is slidably connected to a guide block 117. The upper end of the guide block 117 is fixedly connected to a retaining ball 118, which is slidably connected to a retaining hole 115. The lower end of the guide block 117 is welded to a second spring 119, and the other end of the second spring 119 is welded to the fixed disk 116. Through the setting of structures such as the motor 113 and the toothed plate 111, the monitor 5 can be driven to move and its position can be adjusted. Under the action of structures such as the retaining hole 115 and the retaining ball 118, the fixed disk 116 can be rotated and limited, thereby positioning the monitor 5 for use.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a gear 114 is fixedly sleeved on the outside of the output shaft of the motor 113. The gear 114 meshes with the toothed plate 111. Through the meshing relationship, when the gear 114 rotates, it can drive the toothed plate 111 to move. Multiple locking holes 115 are provided. The multiple locking holes 115 are arranged in a ring array on the mounting cylinder 112. The setting of the locking holes 115 facilitates the use of locking balls 118 for locking.

[0028] The specific implementation process of this utility model is as follows: By pulling the locking block 9 to the right, the locking block 9 moves along the surface of the guide rod 8, and the spring 10 deforms. When the locking block 9 contacts the limiting plate of the guide rod 8, the spring 10 no longer deforms, which can push the monitor 5 to contact the support block 4, and make the screw 7 pass through the support block 4, so that the screw 7 contacts the nut 6, and then push the monitor 5 to rotate, so as to drive the screw 7 to rotate. Under the threaded connection, the screw 7 can be fixed, the monitor 5 can be installed, and the locking block 9 is released so that the spring 10 returns to its deformation, so as to pull the locking block 9 to insert into the screw 7, limit the screw 7, and avoid the problem of vibration and loosening of the screw 7 and the monitor 5.

[0029] The start motor 113 drives the output shaft to rotate, which in turn drives the gear 114 to rotate. In the meshing relationship, the gear 114 pushes the gear plate 111 to move, causing the support frame 3 to slide along the inner wall of the support cylinder 1, which in turn moves the support block 4, ultimately moving the monitor 5 to adjust its position for subsequent monitoring. When the motor 113 drives the output shaft to rotate, it can also drive the fixed disk 116 to rotate. Under the pressure of the inner wall of the clamping hole 115, it can push the clamping ball 11... 8 moves to push the guide block 117 to slide along the inner wall of the fixed plate 116. The second spring 119 deforms, eventually causing the retaining ball 118 to disengage from the retaining hole 115. Under the action of force, the retaining ball 118 slides along the inner wall of the mounting cylinder 112. When the retaining ball 118 slides into the next retaining hole 115, the second spring 119 returns to its original deformation to push the retaining ball 118 into the retaining hole 115, limiting the fixed plate 116, thereby limiting the rotation of the output shaft of the motor 113, and finally positioning the monitor 5.

[0030] This solution utilizes a screw 7, nut 6, and other structural elements to install and use the monitor 5. The guide rod 8, spring 10, and locking block 9 limit the screw 7, preventing vibration and loosening, thus ensuring the long-term stability of the monitor 5. The handle 2 and support cylinder 1 allow for handheld monitoring. The motor 113, gear 114, and toothed plate 111 drive the monitor 5 to move and adjust its position, improving monitoring effectiveness. The locking hole 115, ball 118, and spring 119 limit the rotation of the motor 113's output shaft, thus positioning the monitor 5.
