Description

Technical Field

[0001] The utility model relates to the technical field of ventilation equipment, and more specifically, to a hood which is easy to install. Background Art

[0002] As one of the common ventilation equipment, the hood is usually installed at the vent or exhaust outlet of the fresh air duct. It can effectively prevent external impurities from entering the fresh air duct and reduce the problem of blockage in the fresh air duct.

[0003] Publication No. CN209163364U discloses an exhaust hood, whose technical solution includes a pipeline, a hood body fixedly installed on the front end of the pipeline by threads, and a flange fixedly installed on the rear end of the pipeline, a vertical filter screen mounting plate is provided at the front end of the pipeline, and semicircular filter screens are respectively hinged on both sides of the filter screen mounting plate through hinge shafts, and a torsion spring is sleeved on the hinge shaft, one end of the torsion spring is fixed to the filter screen mounting plate, and the other end is fixed to the semicircular filter screen, the hood body is made of ABS material, and includes a threaded pipe section connected to the pipeline, a clamping ring fixedly sleeved on the outer end of the threaded pipe section and extending toward the inner side of the pipe section, and a windproof hood fixedly installed on the outer end of the threaded pipe section and extending toward the outer side of the pipe section, and the diameter of the clamping ring gradually increases from the outside to the inside.

[0004] When the hood is installed, the above technical solution uses the threaded pipe section to make the hood body and the pipe threadably connected to each other, which is convenient for the staff to install the hood and improves work efficiency. At the same time, the semicircular filter net can filter external impurities and avoid pipe blockage. However, when the hood is installed, the above technical solution only uses the threaded pipe section to connect the hood body and the pipe. If the diameter of the pipe does not match the inner diameter of the hood, the hood body and the pipe will be affected and cannot be installed with each other, affecting the versatility of the hood to the pipe diameter.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a hood that is easy to install, which solves the problem that when the hood is installed, if the diameter of the pipe and the inner diameter of the hood do not match, the hood body and the pipe will be affected and cannot be installed with each other, affecting the versatility of the hood for the pipe diameter.

[0007] The above technical purpose of the utility model is achieved through the following technical scheme: a hood that is easy to install, including a hood body, a plurality of elastic plates are fixedly connected to the inner wall of the hood body, and when the elastic plates are in a natural state, the elastic plates are inclined, and the inner wall of the hood body is slidably connected to an adjustment ring, and the side walls of the plurality of elastic plates are in contact with the side walls of the adjustment ring, and a driving component for driving the adjustment ring to move is provided on the hood body.

[0008] By adopting the above technical solution, when installing the hood body, the bottom of the hood body is inserted into the pipe, and then the driving assembly is used to drive the adjusting ring to start moving downward. At the same time, a number of elastic plates are affected by the pressure applied by the adjusting ring and begin to deform, driving the number of elastic plates to tilt toward the pipe direction, and driving the number of elastic plates and the side walls of the pipe to abut against each other. At this time, the pipe is affected by the number of elastic plates, so that the pipe cannot move, thereby completing the effect of installing the hood. By setting up a number of elastic plates, the driving assembly can be used to change the spacing between the number of elastic plates, so that the spacing between the number of elastic plates matches the mouth shape of the pipe, thereby avoiding the problem of being unable to install due to mismatch between the hood body and the pipe, and improving the versatility of the hood during installation.

[0009] The utility model is further configured as follows: the driving assembly includes a plurality of connecting rods fixedly connected to the side wall of the adjusting ring, the side wall of the hood body is provided with a plurality of sliding grooves for the connecting rods to slide, the side wall of the hood body is threadedly connected with a movable ring, and the side wall of the movable ring is provided with annular grooves for the connecting rods to slide.

[0010] By adopting the above technical solution, when the adjusting ring needs to be driven to move, the moving ring is driven to start rotating. Since the moving ring and the hood body are threadedly connected to each other, the moving ring will be affected and start moving downward. At the same time, the moving ring drives the connecting rod to start sliding in the same direction, and drives the adjusting ring to start moving through the connecting rod, thereby achieving the effect of driving the adjusting ring to move.

[0011] The utility model is further configured that: when the adjusting ring and the bottoms of the plurality of elastic plates are in contact with each other, the ends of the plurality of elastic plates away from the hood body are in contact with each other.

[0012] By adopting the above technical solution, the deformation range of the plurality of elastic plates can be increased, the fixing effect between the hood and pipes of different diameters can be improved, and the versatility of the hood during installation can be further improved.

[0013] The utility model is further configured as follows: a reinforcement ring is threadedly connected to the outer side wall of the hood body, and the thread direction between the reinforcement ring and the hood body is opposite to the thread direction between the adjustment ring and the hood body.

[0014] By adopting the above technical scheme, after a number of elastic plates and pipes abut against each other, the reinforcement ring and the side walls of the movable ring are driven to fit together. At this time, the movable ring is restricted by the reinforcement ring and cannot move upward, thereby avoiding the displacement of the position of the movable ring, thereby improving the stability between the adjustment ring and the hood body. At the same time, by setting the thread direction between the reinforcement ring and the hood body and the thread direction between the adjustment ring and the hood body to be opposite, it is possible to prevent the movable ring from rotating due to friction when the reinforcement ring is rotated after the movable ring and the reinforcement ring fit together, thereby further improving the fixing effect of the reinforcement ring on the movable ring, and avoiding the movement of the movable ring after the elastic plate and the pipe contact each other.

[0015] The utility model is further configured as follows: the outer side wall of the hood body is fixedly connected to a limiting ring.

[0016] By adopting the above technical solution, it is possible to avoid the movable ring and the reinforcement ring from being separated from the side wall of the hood body.

[0017] The utility model is further configured as follows: a protective cover is fixedly connected to the side wall of the limiting ring, the protective cover has elastic deformation capability, the side wall of the protective cover and the adjustment ring and the reinforcement ring are in contact with each other, and when the protective cover is in a natural state, one end of the protective cover away from the limiting ring abuts against the hood body.

[0018] By adopting the above technical scheme, when the hood body and the pipe are installed to each other, since the protective cover has the elastic deformation ability, the protective cover can be flipped up so that the movable ring and the reinforcement ring are in contact with the outside world. After the hood body and the pipe are installed, the protective cover is flipped back to its original position. Through the setting of the protective cover, the movable ring and the reinforcement ring can be protected, and the movable ring and the reinforcement ring are prevented from being exposed to the outside world for a long time, which leads to aging problems at the connection between the movable ring and the reinforcement ring and the hood body, thereby improving the service life of the movable ring and the reinforcement ring. At the same time, after the protective cover is flipped back to its original position, the protective cover and the movable ring and the reinforcement ring are in contact with each other, which can increase the friction between the movable ring and the reinforcement ring and the protective cover, improve the stability between the movable ring and the reinforcement ring, and improve the fixing effect.

[0019] The utility model is further configured as follows: a plurality of the elastic plates are fixedly connected to one side away from the hood body with an elastic ring, and when the plurality of the elastic plates are in a natural state, the elastic ring is in a stretched state.

[0020] By adopting the above technical solution, the force exerted by the flexible ring on the pipeline can be increased, and the fixing effect between the plurality of fixing plates and the pipeline can be improved.

[0021] To sum up, the utility model has the following beneficial effects: when installing the hood body, the adjusting ring is driven by the driving assembly to start moving downward, and at the same time, a number of elastic plates are affected by the pressure applied by the adjusting ring and begin to deform, driving the number of elastic plates to tilt toward the pipe direction, and driving the number of elastic plates and the side walls of the pipe to abut against each other. At this time, the pipe is affected by the number of elastic plates, so that the pipe cannot move, thereby completing the effect of installing the hood. Through the arrangement of the number of elastic plates, the driving assembly can be used to change the spacing between the number of elastic plates, so that the spacing between the number of elastic plates matches the mouth shape of the pipe, thereby avoiding the problem of inability to install due to mismatch between the hood body and the pipe, and improving the versatility of the hood during installation.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] A hood that is easy to install, such as Figure 1-Figure 5 As shown, it includes a hood body 1, and a plurality of elastic plates 2 are fixedly connected to the inner wall of the hood body 1. When the elastic plates 2 are in a natural state, the elastic plates 2 are inclined. An adjusting ring 3 is slidably connected to the inner wall of the hood body 1. The side walls of the plurality of elastic plates 2 are in contact with the side walls of the adjusting ring 3. A driving component for driving the adjusting ring 3 to move is provided on the hood body 1. When installing the hood body 1, the bottom of the hood body 1 is inserted into the pipeline, and then the adjusting ring 3 is driven downward by the driving component to start moving. At the same time, the plurality of elastic plates 2 are exerted by the adjusting ring 3. Due to the influence of pressure, deformation begins to occur, driving the several elastic plates 2 to tilt toward the pipe direction, and driving the several elastic plates 2 and the side walls of the pipe to abut against each other. At this time, the pipe is affected by the several elastic plates 2, which makes it impossible for the pipe to move, thereby completing the effect of installing the hood. By setting up the several elastic plates 2, the distance between the several elastic plates 2 can be changed by utilizing the driving assembly, so that the distance between the several elastic plates 2 matches the mouth shape of the pipe, thereby avoiding the problem of inability to install due to mismatch between the hood body 1 and the pipe, and improving the versatility of the hood during installation.

[0032] like Figure 1-Figure 5 As shown, the driving assembly includes a plurality of connecting rods 4 fixedly connected to the side wall of the adjusting ring 3, a plurality of sliding grooves 5 for the connecting rods 4 to slide are provided on the side wall of the hood body 1, a moving ring 6 is threadedly connected to the side wall of the hood body 1, and an annular groove 7 for the connecting rods 4 to slide is provided on the side wall of the moving ring 6. When it is necessary to drive the adjusting ring 3 to move, the moving ring 6 is driven to start rotating. Since the moving ring 6 and the hood body 1 are threadedly connected to each other, the moving ring 6 will be affected and start to move downward. At the same time, the moving ring 6 drives the connecting rod 4 to start sliding in the same direction, and drives the adjusting ring 3 to start moving through the connecting rod 4, thereby achieving the effect of driving the adjusting ring 3 to move. When the adjusting ring 3 and the bottoms of the plurality of elastic plates 2 contact each other, the ends of the plurality of elastic plates 2 away from the hood body 1 contact each other, which can increase the deformation range of the plurality of elastic plates 2, improve the fixing effect between the hood and pipes of different calibers, and further improve the versatility of the hood during installation.

[0033] like Figure 1-Figure 5As shown, a reinforcement ring 8 is threadedly connected to the outer wall of the hood body 1, and the thread direction between the reinforcement ring 8 and the hood body 1 is opposite to the thread direction between the adjustment ring 3 and the hood body 1. After a number of elastic plates 2 and pipes abut against each other, the reinforcement ring 8 and the side walls of the movable ring 6 are driven to fit together. At this time, the movable ring 6 is restricted by the reinforcement ring 8 and cannot move upward, thereby avoiding the position of the movable ring 6 from being offset, thereby improving the stability between the adjustment ring 3 and the hood body 1. At the same time, by setting the thread direction between the reinforcement ring 8 and the hood body 1 and the thread direction between the adjustment ring 3 and the hood body 1 to be opposite, it is possible to prevent the movable ring 6 from rotating due to friction when the reinforcement ring 8 is rotated after the movable ring 6 and the reinforcement ring 8 are fitted, thereby further improving the fixing effect of the reinforcement ring 8 on the movable ring 6, and avoiding the movable ring 6 from moving after the elastic plate 2 and the pipe are in contact with each other. The outer wall of the hood body 1 is fixedly connected to a limiting ring 9, which can avoid the movable ring 6 and the reinforcement ring 8 from separating from the side wall of the hood body 1.

[0034] like Figure 1-Figure 5 As shown, the side wall of the limiting ring 9 is fixedly connected with a protective cover 10, and the protective cover 10 has elastic deformation ability. The side wall of the protective cover 10 and the adjustment ring 3 and the reinforcement ring 8 are in contact with each other. When the protective cover 10 is in a natural state, the end of the protective cover 10 away from the limiting ring 9 abuts against the hood body 1. When the hood body 1 and the pipeline are installed with each other, since the protective cover 10 has elastic deformation ability, the protective cover 10 can be flipped up, so that the movable ring 6 and the reinforcement ring 8 are in contact with the outside world. After the hood body 1 and the pipeline are installed, the protective cover 10 is flipped back to its original position. By setting the protective cover 10, the movable ring 6 and the reinforcement ring 8 can be protected, and the movable ring 6 and the reinforcement ring 8 are prevented from being exposed to the outside world for a long time, which causes aging problems at the connection between the movable ring 6 and the reinforcement ring 8 and the hood body 1, thereby improving the service life of the movable ring 6 and the reinforcement ring 8. At the same time, after the protective cover 10 is turned back to its original position, the protective cover 10 and the movable ring 6 and the reinforcement ring 8 are in contact with each other, which can increase the friction between the movable ring 6 and the reinforcement ring 8 and the protective cover 10, improve the stability between the movable ring 6 and the reinforcement ring 8, and improve the fixing effect.

[0035] like Figure 1-Figure 5 As shown, a plurality of elastic plates 2 are fixedly connected to an elastic ring 11 on one side away from the hood body 1. When the plurality of elastic plates 2 are in a natural state, the elastic ring 11 is in a stretched state, which can increase the force exerted by the flexible ring on the pipeline and improve the fixing effect between the plurality of fixed plates and the pipeline.

[0036] The utility model is used normally as follows: when installing the hood body 1, the bottom of the hood body 1 is inserted into the pipe, and then the moving ring 6 is driven to start rotating. Since the moving ring 6 and the hood body 1 are threadedly connected to each other, the moving ring 6 will be affected and start to move downward. At the same time, the moving ring 6 drives the connecting rod 4 to start sliding in the same direction, and drives the adjusting ring 3 to start moving downward through the connecting rod 4. At the same time, the elastic plates 2 are affected by the pressure applied by the adjusting ring 3 and begin to deform, driving the elastic plates 2 to tilt toward the pipe direction, and driving the elastic plates 2 and the side walls of the pipe to abut against each other. At this time, the pipe is affected by the elastic plates 2, so that the pipe cannot move, thereby completing the effect of installing the hood. Through the setting of the elastic plates 2, the distance between the elastic plates 2 can be changed by using the driving assembly, so that the distance between the elastic plates 2 matches the mouth shape of the pipe, thereby avoiding the problem of being unable to install due to the mismatch between the hood body 1 and the pipe, and improving the versatility of the hood during installation.

[0037] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
