Description

Technical Field

[0001] The utility model relates to the field of mounting and fixing devices, in particular to a mounting and fixing device for a noise detector. Background Art

[0002] A noise detector is an instrument used to monitor the noise level in the environment. It is used to measure and record the noise level. It is widely used in environmental protection, industry, transportation, medical care, construction, aviation and aerospace to protect people's hearing and health. The noise detector is installed in a suitable location by installing a fixture.

[0003] According to a device for mounting and fixing a noise detector for environmental testing disclosed on the patent website (authorization announcement number: CN220082613 U), "a fixing plate is fixedly mounted on the outer wall of the support column, and bolts are fixedly mounted on the four corner edges of the fixing plate."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During the use of this utility model, since the device is inserted into the ground through the support column and then connected and fixed by bolts, when the device needs to be fixed in a position where the soil is loose, the bolts cannot be used, and the device can only be inserted into the soil through the support column. Since the soil is relatively loose, the position of the support device cannot be stabilized, and it is easy to fall over when receiving external force, causing damage to the noise detector. Therefore, it is necessary to improve a noise detector installation and fixing device to solve the above problem. Utility Model Content

[0006] In order to overcome the problem that a single support rod and bolt cannot stabilize the fixing device in soft soil.

[0007] The technical solution of the utility model is: a noise detector installation and fixing device, including a mounting frame, a placement plate and an insertion rod, and also including a third gear, a second limiting plate, a drill bit, a positioning assembly and a mounting assembly. The left and right sides of the mounting frame are fixedly connected with the placement plates, the bottom of the mounting frame is fixedly connected with the insertion rod, the interior of the mounting frame is provided with a positioning assembly, the top of the mounting frame is provided with a mounting assembly, the interior of the positioning assembly is provided with a third gear, the bottom of the third gear is fixedly connected with the second limiting plate, the bottom of the second limiting plate is fixedly connected with the drill bit, the drill bit is rotated to drill into the soil, and the drill bit is extended into the soil to position the device.

[0008] Preferably, a worker steps on the top of the placement plate or places heavy objects to increase the weight of the device, and the motor rotates to drive the first limit plate to rotate on the outside of the threaded rod, thereby raising and lowering the height of the drill bit. At the same time, the second gear drives the third gear to accelerate, so that the drill bit rotates and drills into the soil, and cooperates with the insertion rod to position the mounting frame. The sliding rod is pulled to drive the push plate to separate from the noise detector body, and the noise detector body can be quickly removed. The push plate is pushed by the spring to cooperate with the positioning frame to position the noise detector body, and the noise detector body can be quickly installed and removed.

[0009] Preferably, the mounting frame is provided with a through hole at a position corresponding to the drill bit, and the drill bit passes through the through hole, so that the drill bit passes through the through hole to prevent the position of the drill bit from being affected and the drill bit from being raised or lowered, thereby drilling into the ground.

[0010] Preferably, the positioning assembly includes a movable plate, which is slidably connected to the inside of the mounting frame, and the top of the movable plate is fixedly connected to a motor, and the output end of the motor is fixedly connected to a first gear, the outside of the first gear is meshed with a second gear, and the inside of the second gear is fixedly connected to a first limiting plate, the first limiting plate is rotatably connected to the inside of the movable plate, the internal thread of the first limiting plate is connected to a threaded rod, and the threaded rod is fixedly connected to the inside of the mounting frame, the second gear is meshed with the outside of the third gear, and the second limiting plate is rotatably connected to the inside of the movable plate, and the drill bit is lowered and rotated by the motor, drilling deep into the soil, and cooperating with the insertion rod to support and position the mounting frame, thereby ensuring the stability of the mounting frame and preventing the mounting frame from tipping over when the noise detector body is working.

[0011] Preferably, the movable plate opens limiting holes at corresponding positions of the second limiting plate and the first limiting plate, and the second limiting plate and the first limiting plate rotate inside the limiting holes. The second limiting plate and the first limiting plate are limited respectively by the two limiting holes. While positioning the third gear and the second gear, the second limiting plate and the first limiting plate rotate stably and smoothly to prevent jamming.

[0012] Preferably, the diameter of the second gear is larger than the diameter of the third gear. Since the second gear is larger than the third gear, when the second gear engages with the third gear to rotate the third gear, the second gear accelerates the rotation of the third gear, thereby making the drill bit rotate faster while moving, and can easily drill into the soil.

[0013] Preferably, the mounting assembly includes a protective shell, which is fixedly connected to the top of the mounting frame, a positioning frame fixedly connected to the interior of the protective shell, a noise detector body movably connected to the interior of the positioning frame, a sliding rod slidably connected to the interior of the protective shell, a pull ring fixedly connected to the front of the sliding rod, a push plate fixedly connected to the back of the sliding rod, a spring fixedly connected between the push plate and the protective shell, the noise detector body is protected by the protective shell, and the push plate is pushed by the spring to squeeze the noise detector body, thereby locating the position of the noise detector body, which is convenient for quick replacement and installation of the noise detector body.

[0014] Preferably, the positioning frame is provided with a groove at the corresponding position of the noise detector body, and the noise detector body is movably connected inside the groove. The push plate is in contact with the noise detector body, and the noise detector body is limited by the groove of the positioning frame. The push plate is used to support the noise detector body, which can effectively prevent the noise detector body from leaving the positioning frame and stabilize the position of the noise detector body.

[0015] Beneficial effects of the utility model:

[0016] 1. The second gear accelerates the rotation speed of the drill bit, so that the drill bit descends and screws into the soil until it drills to a hard position deep in the soil. The support of the drill bit and the support of the insertion rod can fix the position of the mounting frame to prevent the mounting frame from tipping over during operation, making the fixation more stable and firm.

[0017] 2. The groove of the positioning frame preliminarily limits the noise detector body, and then the spring pushes the push plate to support the noise detector body to position the noise detector body, and the push plate can be pulled away from the noise detector body, thereby realizing the rapid disassembly and assembly of the noise detector body, which is more convenient and quick to use.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See also Figure 1-Figure 4 The utility model provides an embodiment: a noise detector installation and fixing device, including a mounting frame 1, a placement plate 4 and an insertion rod 5, and also includes a third gear 27, a second limiting plate 28, a drill bit 29, a positioning assembly and a mounting assembly. The left and right sides of the mounting frame 1 are fixedly connected to the placement plate 4, the bottom of the mounting frame 1 is fixedly connected to the insertion rod 5, a positioning assembly is provided inside the mounting frame 1, and a mounting assembly is provided on the top of the mounting frame 1. The third gear 27 is provided inside the positioning assembly, the bottom of the third gear 27 is fixedly connected to the second limiting plate 28, and the bottom of the second limiting plate 28 is fixedly connected to the drill bit 29, which is rotated to drill into the soil and extended into the soil by the drill bit 29 to position the device. By the staff stepping on the top of the placement plate 4 or placing heavy objects, the installation is increased. The weight of the device is placed, and the motor 22 rotates to drive the first limit plate 25 to rotate on the outside of the threaded rod 26, thereby raising and lowering the height of the drill bit 29. At the same time, the second gear 24 drives the third gear 27 to accelerate, so that the drill bit 29 rotates to drill into the soil, and cooperates with the insertion rod 5 to position the mounting frame 1, and pulls the slide bar 34 to drive the push plate 36 to disengage from the noise detector body 33, so that the noise detector body 33 can be quickly taken out. The push plate 36 is pushed by the spring 37 to cooperate with the positioning frame 32 to position the noise detector body 33, and the noise detector body 33 is quickly installed and taken out. The mounting frame 1 has a through hole at the corresponding position of the drill bit 29, and the drill bit 29 passes through the through hole. The drill bit 29 passes through the opened through hole to prevent affecting the position of the drill bit 29 from being affected, thereby drilling into the ground through the drill bit 29.

[0025] See also Figure 1-Figure 3In this embodiment, the positioning assembly includes a movable plate 21, which is slidably connected to the inside of the mounting frame 1. A motor 22 is fixedly connected to the top of the movable plate 21. The output end of the motor 22 is fixedly connected to a first gear 23. The outside of the first gear 23 is meshed with a second gear 24. The inside of the second gear 24 is fixedly connected to a first limiting plate 25. The first limiting plate 25 is rotatably connected to the inside of the movable plate 21. The internal thread of the first limiting plate 25 is connected to a threaded rod 26. The threaded rod 26 is fixedly connected to the inside of the mounting frame 1. The second gear 24 is meshed with the outside of the third gear 27. The second limiting plate 28 is rotatably connected to the inside of the movable plate 21. The motor 22 causes the drill bit 29 to descend and rotate at the same time, drilling deep into the soil, cooperating with the insertion rod 5 to support and position the mounting frame 1, thereby ensuring the stability of the mounting frame 1. To prevent the mounting frame 1 from tipping over during operation of the noise detector body 33, the movable plate 21 opens limiting holes at corresponding positions of the second limiting plate 28 and the first limiting plate 25, and the second limiting plate 28 and the first limiting plate 25 rotate inside the limiting holes. The second limiting plate 28 and the first limiting plate 25 are limited respectively by the two limiting holes. While positioning the third gear 27 and the second gear 24, the second limiting plate 28 and the first limiting plate 25 rotate stably and smoothly to prevent jamming. The diameter of the second gear 24 is larger than the diameter of the third gear 27. Because the second gear 24 is larger than the size of the third gear 27, the second gear 24 engages the third gear 27 to rotate the third gear 27, thereby realizing that the second gear 24 accelerates the rotation of the third gear 27, so that the rotation speed of the drill bit 29 is higher while moving, and it can easily drill into the soil.

[0026] See also Figure 1 、 Figure 4 In this embodiment, the mounting assembly includes a protective shell 31, which is fixedly connected to the top of the mounting frame 1. A positioning frame 32 is fixedly connected to the interior of the protective shell 31, and a noise detector body 33 is movably connected to the interior of the positioning frame 32. A slide rod 34 is slidably connected to the interior of the protective shell 31, and a pull ring 35 is fixedly connected to the front of the slide rod 34. A push plate 36 is fixedly connected to the back of the slide rod 34. A spring 37 is fixedly connected between the push plate 36 and the protective shell 31. The protective shell 31 protects the noise detector body 33, and the spring 37 pushes the push plate 36 to squeeze the noise detector body 33. The noise detector body 33 is positioned so as to locate the position of the noise detector body 33, which is convenient for quick replacement and installation of the noise detector body 33. The positioning frame 32 is provided with a groove at the corresponding position of the noise detector body 33, and the noise detector body 33 is movably connected inside the groove. The push plate 36 is in contact with the noise detector body 33, and the noise detector body 33 is limited by the groove of the positioning frame 32. The push plate 36 is used to support the noise detector body 33, which can effectively prevent the noise detector body 33 from escaping from the positioning frame 32 and stabilize the position of the noise detector body 33.

[0027] When working, the staff or a heavy object is placed on the top of the placement plate 4 to increase the weight of the mounting frame 1, and then the insertion rod 5 is inserted into the soil through the mounting frame 1, and the motor 22 drives the first gear 23, the first gear 23 drives the second gear 24, and the second gear 24 drives the first limiting plate 25. The first limiting plate 25 rotates on the outside of the threaded rod 26, so that the movable plate 21 rotates inside the mounting frame 1, thereby adjusting the height of the movable plate 21. At the same time, the second gear 24 drives the third gear 27, the third gear 27 drives the second limiting plate 28, and the second limiting plate 28 drives the drill bit 29. When the drill bit 29 touches the ground, it is screwed into the soil and screwed to a deep depth to cooperate with the insertion rod 5 to fix the position of the mounting frame 1. Pull the pull ring 35 to drive the slide rod 34, and the slide rod 34 drives the push plate 36. The push plate 36 compresses the spring 37. The spring 37 is used to reset the push plate 36. The push plate 36 is separated from the noise detector body 33, and the noise detector body 33 can be taken out from the inside of the positioning frame 32 for replacement.

[0028] Through the above steps, the drill bit 29 is lowered and screwed into the soil until it reaches a hard position deep in the soil. The support of the drill bit 29 and the support of the insertion rod 5 can fix the position of the mounting frame 1, thereby solving the problem that a single support rod and bolt cannot stably fix the device in a soft soil position.
