Description

Technical Field

[0001] This utility model belongs to the field of ventilation equipment installation technology, and in particular relates to an installation component for ventilation equipment. Background Technology

[0002] In the process of warehousing, especially when storing fruits and vegetables, ventilation is particularly important to ensure sufficient oxygen in the storage environment, and ventilation equipment is required for ventilation.

[0003] Existing ventilation equipment is typically installed by bolting multiple bolts into ventilation holes in the warehouse wall. The fan inside the equipment draws in outside air for ventilation. However, the installation process involves tightening multiple bolts, which is cumbersome and inefficient. Therefore, we propose an installation component for ventilation equipment. Utility Model Content

[0004] The purpose of this invention is to provide an installation component for a ventilation device to solve the problems mentioned in the background section.

[0005] In view of this, the present invention provides an installation component for a ventilation device, including a storage compartment, a ventilation opening on one side of the storage compartment, and a duct fixedly installed inside the ventilation opening; Multiple mounting ears are fixedly mounted on the surface of the air duct. Multiple mounting slots are provided on one side of the storage compartment, and threaded holes are provided in the mounting slots. Multiple mounting ears are fixedly mounted in the threaded holes by mounting bolts. A positioning cover is fitted to the surface of the air duct. An internal toothed ring is rotatably mounted on one side of the positioning cover. Multiple bolt cylinders are rotatably mounted on one side of the positioning cover. The surface of the bolt cylinders is provided with teeth. The bolt cylinders engage with the internal toothed rings through the teeth. A knob head is fixedly mounted on one end of the mounting bolts. The knob head is fitted against the inner wall of the bolt cylinders.

[0006] In this technical solution, the storage compartment serves as the installation base, with a ventilation opening on one side. A duct is fixedly installed inside the ventilation opening for ventilation. Four mounting ears are installed at equal angles on the surface of the duct. The storage compartment, located in the ventilation opening area, has four mounting slots at equal angles corresponding to the mounting ears. Threaded holes are formed in the mounting slots for mounting bolts. Multiple mounting ears are fixed into the threaded holes by mounting bolts, connecting the duct to the storage compartment. A positioning cover is fitted against the surface of the duct. An internal gear ring is rotatably mounted on one side of the positioning cover via a bearing. Four bolt cylinders at equal angles are also rotatably mounted on one side of the positioning cover via a bearing, corresponding to the number of mounting bolts (8). The bolt cylinders have teeth machined on their surfaces, and the shape of the knob head matches the inner hole shape of the bolt cylinder, allowing it to fit against the inner wall of the bolt cylinder and be rotated by it. During installation, first, place the duct into the ventilation opening, aligning its mounting ears with the mounting slots on the storage compartment. Insert the knob head of the mounting bolt into the corresponding bolt cylinder. Then, place the positioning cover with the bolt cylinders onto the duct. At this point, simply rotate the internal gear ring. The rotation of the internal gear ring simultaneously drives all the bolt sleeves that mesh with it to rotate synchronously. Each rotating bolt sleeve drives the knob head inside to rotate, thereby causing all the mounting bolts to be screwed into or out of the threaded holes on the storage compartment simultaneously, realizing the rapid installation or disassembly of the air duct, improving the installation and disassembly efficiency of the ventilation equipment, and saving a lot of manpower and time.

[0007] In the above technical solution, further, a plurality of flip-out openings are provided on one side of the storage compartment, and an installation frame is fixedly installed in each of the plurality of flip-out openings. A flip-out piece is rotatably installed on the inner wall of the installation frame through a torsion spring shaft. A positioning rod is fixedly installed at one end of the flip-out piece, and a positioning groove is provided on the surface of the knob head.

[0008] In this technical solution, four equally spaced flip-out openings are provided on one side of the storage compartment. Each flip-out opening contains a fixed mounting frame. A torsion spring shaft, with a rotating shaft equipped with a torsion spring, automatically resets. A flip-out piece is rotatably mounted on the inner wall of the mounting frame via the torsion spring shaft. A cylindrical positioning rod is fixedly mounted at one end of the flip-out piece. Multiple equally spaced positioning grooves are provided on the surface of the knob head. When the mounting bolts are tightened and the knob head reaches its final position, the positioning cover is removed. At this time, the flip-out piece, originally pressed down by the guide block on the positioning cover, automatically springs back to its original position under the elastic force of the torsion spring shaft. The springing flip-out piece causes its positioning rod to pop out and precisely engage in the positioning groove on the surface of the knob head. This effectively prevents the mounting bolts from loosening or even falling off due to vibration during equipment operation, greatly improving the reliability and safety of the connection and eliminating the need for frequent subsequent inspection and tightening maintenance.

[0009] In the above technical solution, further, a plurality of positioning blocks are fixedly installed on one side of the positioning cover, an L-shaped rod is fixedly installed on one side of the positioning block, and a guide block is fixedly installed on the other end of the L-shaped rod.

[0010] In this technical solution, when the installer places the positioning cover onto the air duct, the guide block at the end of the L-shaped rod will insert into the mounting frame before the positioning cover body. The inclined surface of the guide block will press against the flip plate, causing it to rotate and retract against the force of the torsion spring, thus making room for the rotation of the knob head and the positioning cover to be in place. This ensures that the operation of the fastening tools will not be hindered during installation, and also limits the positioning cover to prevent it from rotating on its own.

[0011] In the above technical solution, furthermore, magnets are fixedly installed on the inner walls of the plurality of bolt cylinders.

[0012] In this technical solution, the knob head is made of steel. When the knob head of the mounting bolt is inserted into the bolt cylinder, the magnet will attract the knob head, preventing the mounting bolt from falling out of the bolt cylinder during the installation of the positioning cover. This facilitates one-handed operation and improves the installation experience.

[0013] In the above technical solution, a fan is further fixedly installed on the inner wall of the air duct.

[0014] In this technical solution, the fan rotates after being powered on, generating airflow that forces external air into the storage chamber or extracts air from the chamber, thus achieving ventilation.

[0015] In the above technical solution, a dustproof net is further fixedly installed at one end of the air duct.

[0016] In this technical solution, a dustproof net covers the air inlet of the air duct to filter dust.

[0017] In the above technical solution, further, the extension length of the guide block on the side near the storage compartment is greater than the end length of the knob head on the side near the storage compartment.

[0018] In this technical solution, it is ensured that during installation, the guide block always contacts the flip plate before the knob head and presses it down, creating space for the knob head to pass smoothly and avoiding collision interference.

[0019] The beneficial effects of this utility model are: 1. The installation components of this ventilation equipment involve inserting the inner wall of the positioning cover into the surface of the air duct, inserting the mounting bolts into the threaded holes of the mounting slots, keeping the positioning cover stationary, rotating the inner gear ring, which in turn drives multiple bolt cylinders to rotate, which in turn drives the corresponding knob heads to rotate, and the knob heads to drive the corresponding mounting bolts to rotate. The mounting bolts pass through the mounting ears and are screwed into the threaded holes to install and fix the air duct. The simultaneous tightening of multiple mounting bolts improves installation efficiency.

[0020] 2. The installation components of this ventilation equipment have a positioning cover inserted into the surface of the air duct. The positioning cover drives multiple L-shaped rods to move, and the L-shaped rods drive corresponding guide blocks to move, aligning the guide blocks with the inner wall of the mounting frame, so that they press and guide the flipping plate. Under the action of the guide blocks, the flipping plate flips counterclockwise. After the air duct is installed, the positioning cover is pulled out. When the positioning cover is pulled out, it drives the guide blocks to detach from the mounting frame. At this time, the flipping plate is reset under the action of the torsion spring shaft, driving the positioning rod to move and fit into the positioning groove on the surface of the knob head, thus avoiding the vibration of the fan during operation that could cause the mounting bolts to loosen.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0025] Example 1: This example provides an installation component for a ventilation device, including a storage compartment 1, a ventilation opening 4 on one side of the storage compartment 1, and a duct 2 fixedly installed inside the ventilation opening 4; Multiple mounting ears 5 are fixedly installed on the surface of the air duct 2. Multiple mounting slots are provided on one side of the storage compartment 1, and threaded holes are provided in the mounting slots. Multiple mounting ears 5 are fixedly installed in the threaded holes by mounting bolts 8. A positioning cover 3 is attached to the surface of the air duct 2. An internal toothed ring 9 is rotatably installed on one side of the positioning cover 3. Multiple bolt cylinders 10 are rotatably installed on one side of the positioning cover 3. The surface of the bolt cylinders 10 is provided with teeth. The bolt cylinders 10 mesh with the internal toothed ring 9 through the teeth. A knob head 18 is fixedly installed on one end of the mounting bolt 8. The knob head 18 is attached to the inner wall of the bolt cylinder 10.

[0026] The storage compartment 1 serves as the installation base, with a ventilation opening 4 on one side. A duct 2 is fixedly installed inside the ventilation opening 4 for ventilation. Four mounting ears 5 are installed at equal angles on the surface of the duct 2. The storage compartment 1 has four mounting slots at equal angles in the area of ​​the ventilation opening 4, corresponding to the positions of the mounting ears 5. Threaded holes are opened in the mounting slots for mounting bolts 8 for fixing. Multiple mounting ears 5 are fixed in the threaded holes by mounting bolts 8, realizing the connection between the duct 2 and the storage compartment 1. The positioning cover 3 is installed against the surface of the duct 2 with its inner wall attached. An internal toothed ring 9 is rotatably installed on one side of the positioning cover 3 via a bearing. Four bolt cylinders 10 at equal angles are also rotatably installed on one side of the positioning cover 3 via a bearing, the number corresponding to the mounting bolts 8. The surface of the bolt cylinders 10 is machined with teeth. The shape of the knob head 18 matches the inner hole shape of the bolt cylinder 10, so that it can fit against the inner wall of the bolt cylinder 10 and be driven to rotate. During installation, the duct 2 is first placed into the ventilation opening 4, so that its mounting ears 5 are aligned with the mounting slots on the storage compartment 1. Insert the knob head 18 of the mounting bolt 8 into the corresponding bolt sleeve 10. Then, place the positioning cap 3, which is fitted with the bolt sleeve 10, onto the air duct 2. At this point, simply rotate the internal gear ring 9. The rotation of the internal gear ring 9 will simultaneously drive all the bolt sleeves 10 that are engaged with it to rotate synchronously. Each rotating bolt sleeve 10 will drive the knob head 18 inside it to rotate, thereby causing all the mounting bolts 8 to be screwed into or out of the threaded holes on the storage compartment 1 synchronously, realizing the rapid installation or disassembly of the air duct 2, improving the installation and disassembly efficiency of the ventilation equipment, and saving a lot of manpower and time.

[0027] Example 2: This example provides an installation component for a ventilation device. In addition to the technical solutions of the above examples, it also has the following technical features: a plurality of flip-out openings are provided on one side of the storage compartment 1, and an installation frame 6 is fixedly installed in each of the plurality of flip-out openings. A flip-out piece 13 is rotatably installed on the inner wall of the installation frame 6 through a torsion spring shaft 12. A positioning rod 14 is fixedly installed at one end of the flip-out piece 13, and a positioning groove is provided on the surface of the knob head 18.

[0028] The storage compartment 1 has four equally spaced flip-out openings on one side, each containing a mounting frame 6. A torsion spring shaft 12, a rotating shaft with a torsion spring, automatically resets. A flip-out piece 13 is rotatably mounted on the inner wall of the mounting frame 6 via the torsion spring shaft 12. A cylindrical positioning rod 14 is fixedly mounted at one end of the flip-out piece 13. Multiple equally spaced positioning grooves are formed on the surface of the knob head 18. When the mounting bolt 8 is tightened and the knob head 18 reaches its final position, the positioning cover 3 is removed. At this time, the flip-out piece 13, originally pressed down by the guide block 17 on the positioning cover 3, automatically springs back to its original position under the elastic force of the torsion spring shaft 12. The springing flip-out piece 13 causes its positioning rod 14 to pop out and fit precisely into the positioning groove on the surface of the knob head 18. This effectively prevents the mounting bolt 8 from loosening or even falling off due to vibration during operation, greatly improving the reliability and safety of the connection and eliminating the need for frequent subsequent inspection and tightening maintenance.

[0029] Example 3: This example provides an installation component for a ventilation device. In addition to the technical solutions of the above examples, it also has the following technical features: a plurality of positioning blocks 15 are fixedly installed on one side of the positioning cover 3, an L-shaped rod 16 is fixedly installed on one side of the positioning block 15, and a guide block 17 is fixedly installed on the other end of the L-shaped rod 16.

[0030] When the installer places the positioning cover 3 onto the air duct 2, the guide block 17 at the end of the L-shaped rod 16 will insert into the mounting frame 6 before the main body of the positioning cover 3. The inclined surface of the guide block 17 will press against the flip piece 13, causing it to rotate and retract against the force of the torsion spring, thus making room for the rotation of the knob head 18 and the positioning cover 3 to be in place. This ensures that the operation of the fastening tools will not be hindered during the installation process, and also limits the positioning cover 3 to prevent it from rotating on its own.

[0031] Example 4: This example provides an installation component for a ventilation device. In addition to the technical solutions of the above examples, it also has the following technical features: magnets 11 are fixedly installed on the inner walls of multiple bolt cylinders 10.

[0032] The knob head 18 is made of steel. When the knob head 18 of the mounting bolt 8 is inserted into the bolt cylinder 10, the magnet 11 will attract the knob head 18 to prevent the mounting bolt 8 from falling out of the bolt cylinder 10 during the installation of the positioning cover 3. This facilitates one-handed operation and improves the installation experience.

[0033] Example 5: This example provides an installation component for a ventilation device. In addition to the technical solutions of the above examples, it also has the following technical features: a fan 19 is fixedly installed on the inner wall of the ventilation duct 2.

[0034] When the fan 19 is powered on, it rotates and generates airflow, which forces the outside air into the storage chamber 1 or extracts the air from the chamber to achieve ventilation.

[0035] Example 6: This example provides an installation component for a ventilation device. In addition to the technical solutions of the above examples, it also has the following technical features: a dustproof net 7 is fixedly installed at one end of the air duct 2.

[0036] The dustproof net 7 covers the air inlet of the air duct 2 and is used to filter dust.

[0037] Example 7: This example provides an installation component for a ventilation device. In addition to the technical solutions of the above examples, it also has the following technical features: the extension length of the guide block 17 near the storage compartment 1 is greater than the end length of the knob head 18 near the storage compartment 1.

[0038] This design ensures that during installation, the guide block 17 always contacts the flip plate 13 before the knob head 18 and presses it down, creating space for the knob head 18 to pass smoothly and avoiding collision interference.

[0039] Working principle: When installing the device, first insert the air duct 2 into the ventilation port 4, and attach multiple mounting ears 5 to the corresponding mounting grooves. Then, insert the knob head 18 at one end of multiple mounting bolts 8 into the inner wall of the bolt cylinder 10, and under the action of the magnet 11, attract the mounting bolts 8 into the bolt cylinder 10. Insert the positioning cover 3 into the surface of the air duct 2, and the positioning cover 3 will drive multiple L-shaped rods 16 to move. The L-shaped rods 16 will drive the corresponding guide blocks 17 to move. Align the guide blocks 17 with the inner wall of the mounting frame 6 so that they can squeeze and guide the flipping piece 13. Under the action of the guide blocks 17, the flipping piece 13 will flip counterclockwise. At this time, the mounting bolt 8 will be inserted into the threaded hole of the mounting groove. Keep the positioning cover 3 stationary and rotate the inner toothed ring 9. The inner toothed ring 9 will drive multiple bolt cylinders 10 to rotate. The bolt cylinders 10 will drive the corresponding knob heads 18 to rotate. The knob heads 18 will drive the corresponding mounting bolts 8 to rotate. The mounting bolts 8 will pass through the mounting ears 5 and be screwed into the threaded holes to install and fix the air duct 2. After the air duct 2 is installed, the positioning cover 3 is pulled out. When the positioning cover 3 is pulled out, it causes the guide block 17 to detach from the mounting frame 6. At this time, the flip piece 13 is reset under the action of the torsion spring shaft 12, which drives the positioning rod 14 to move and make it fit into the positioning groove on the surface of the knob head 18 (if it does not fit successfully, during subsequent use, the knob head 18 will be slightly offset due to vibration, and the positioning rod 14 will automatically fit into the positioning groove to complete the locking), thereby locking the knob head 18 and completing the secondary fixation of the air duct 2. When in use, by starting the fan 19 inside the air duct 2, the fan 19 draws outside air into the storage chamber 1 through the dustproof net 7, thus ventilating the storage chamber 1.
