Detailed Description
The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes will be apparent to those skilled in the art as long as they are within the spirit and scope of the present invention as defined and defined by the appended claims, and all inventions contemplated by the present invention are protected.
As shown in FIG. 1, the indoor anti-falling net for children comprises a protective net 2 and a direct current motor 1 installed on a wall body at the edge of the top end side of a window, wherein the mesh size of the protective net 2 is less than 10mm multiplied by 10 mm; due to the arrangement of the mesh size of the protective net 2, after the protective net 2 covers the window, children cannot throw out objects with larger sizes through the window, and the risk of throwing objects at high altitude is reduced.
An installation rod 3 stretching across a window is fixedly installed on an output shaft of the direct current motor 1, and the other end of the installation rod 3 is installed on a bearing seat 31 fixed on a wall body through a bearing, so that when the direct current motor 1 drives the installation rod 3 to rotate, the installation rod 3 and the stability of the protective net 2 on the installation rod are guaranteed. Preferably, the mounting rod 3 is flush with or slightly above the top end of the window, which facilitates the mounting of the bearing housing 31.
One side of the protective net 2 is connected to the mounting rod 3, and the other side is connected to the connecting rod 5; the sliding rails 4 are arranged on the wall bodies on the two sides of the window, sliding grooves in the sliding rails 4 are T-shaped grooves, and the specific installation positions of the sliding rails 4 are different due to the positions of the wall bodies on the two sides of the window.
As shown in fig. 3, mounting holes 51 are formed in two ends of the connecting rod 5 or wall bodies adjacent to the two ends, and a T-shaped slider which is matched with the slide rail 4 and used for enabling the connecting rod 5 to slide along the slide rail 4 under gravity is installed in one of the mounting holes 51 at the two ends of the connecting rod 5.
In implementation, according to the scheme, when the wall body close to the side edge of the window is perpendicular to the window, the T-shaped sliding block is preferably arranged in the mounting hole 51 at the end part of the connecting rod 5; the T-shaped block is mounted in a mounting hole 51 in the wall of the tie bar when the wall immediately adjacent the side edge of the window is parallel to the window.
After the installation holes 51 and the T-shaped sliding blocks are arranged in the above mode, the indoor anti-falling net for children can be suitable for a bay window, a French window and a window formed by directly forming holes in a wall body (the thickness of the window is equal to that of the wall body).
The locking devices 6 used for locking the connecting rods 5 sliding into the windows are respectively arranged on the ground right below the two ends of the window; a weighing sensor 7 is arranged on the ground at a set distance from the locking device 6, a pyroelectric infrared sensor is arranged on a wall body perpendicular to the weighing sensor 7, and both the weighing sensor 7 and the pyroelectric infrared sensor are electrically connected with the storage battery and the controller; the direct current motor 1 and the controller are connected with the storage battery, and the direct current motor is electrically connected with the controller through an AQMH2403ND direct current motor driver.
The model of the pyroelectric infrared sensor is LH 1958; the controller adopts an STC51 singlechip; the weighing sensor 7 is an LC401/LCM401 series weighing sensor; the storage battery is connected with a plug and is connected with the mains supply through the plug for charging.
The anti-falling net is powered by the storage battery, so that the anti-falling net is not influenced by external power failure as long as the storage battery is charged, and the anti-falling net is ensured to continuously and normally work through periodic charging in the using process.
The indoor anti-falling net for children of the scheme is used, the threshold value of the controller starting the direct current motor 1 is set according to the weight of children in the family, for example, the weight of children in the family is 20kg, a user can set the range of the threshold value to be 15kg to 30kg, as long as the data collected by the weighing sensor 7 is located in the range, and meanwhile, the pyroelectric infrared sensor feeds back that someone is located in the region, the controller starts the direct current motor 1 to rotate positively, and the protective net 2 is put down to cover the whole window.
The solution generally provides the load cell 7 immediately in front of the locking device 6, with a monitoring range covering an area of length at least equal to the width of the window and width equal to 0.5 m; through weighing sensor 7 and pyroelectric infrared sensor's mutually supporting like this, just can realize getting into this regional people or child's judgement.
As shown in fig. 2 and 4, in an embodiment of the present invention, the locking device 6 includes a base 61 and a bolt 62 that is engaged with a locking hole of the base 61 to fix the base 61 to the ground; the base 61 is connected with an annular snap ring 64 through a support rod 63, the opening of the snap ring 64 is connected with a horn-shaped socket 65, the diameter of the snap ring 64 and the opening width of the upper end of the socket 65 are both larger than the diameter of the connecting rod 5, and the opening width of the snap ring 64 is smaller than the diameter of the connecting rod 5.
The snap ring 64 and the socket 65 may be made of a metal material having a certain elasticity, or a metal material having no elasticity, but the snap ring 64 and the socket 65 need to be made into a thin-wall structure, so that the snap ring 64 and the socket 65 can have elasticity through the thin-wall structure.
After the locking device 6 adopts the structure, when the connecting rod 5 slides downwards to the socket 65, the connecting rod 5 can smoothly enter the socket 65 due to the large size of the socket 65, and the arrangement of the shape of the socket 65 can play a role in guiding; since the connecting rod 5 is subjected to a large acceleration when sliding down rapidly, the force is relatively large, and although the size of the opening in the snap ring 64 is smaller than the diameter of the connecting rod 5, the connecting rod 5 can slide into the snap ring 64 smoothly under the action of the acceleration and the elasticity of the snap ring 64.
After the connecting rod 5 enters the snap ring 64, because the opening of the snap ring 64 is smaller than the diameter of the connecting rod 5, a child cannot take out the connecting rod 5 from the snap ring 64, so that the anti-falling net forms a net-shaped structure for sealing a window at the window, and the safety protection of the child is achieved.
When the adult nurses children at home, the adult can shift out the snap ring 64 with strength connecting rod 5, and the rethread controller drives direct current motor 1 and reverses, can accomodate the top to the window with preventing weighing down the net.
Specifically, the control panel connected with the controller can be arranged on a wall body adjacent to the window and on a wall body which cannot be hooked by children, and the control panel is provided with a forward rotation button and a reverse rotation button for opening forward rotation and reverse rotation of the direct current motor 1 and a shutdown button for closing the direct current motor 1.
During the implementation, the cover is equipped with the arc lid 66 that covers base 61 on the preferred branch 63 of this scheme, and the through-hole that supplies bolt 62 to pass is seted up to arc lid 66 and the corresponding position department in locking hole, and the setting of arc lid 66 can shelter from bolt 62 on base 61 and the base 61 to on avoiding the people to walk carelessly playing the bolt 62 that the installation back is not eyed, arouse the foot be injured.
To sum up, the indoor net of preventing weighing down of children that this scheme provided can confirm whether children to the people that gets into the window through mutually supporting of controller, weighing sensor 7 and the pyroelectric infrared sensor that set up, later through putting down to prevent weighing down the net and realize the safety protection to children.
