[0015] Beneficial effect: The present invention adds a rubber frame to the mounting plate. When a falling object falls onto the protective frame, the falling object will fall onto the rubber frame and impact the rubber frame. The force generated by the impact of the falling object is directly applied to the mounting plate and the rubber frame. The rubber frame will weaken the impact of the falling object and reduce the force generated by the impact. The force is then applied to the mounting plate to reduce damage to the mounting plate.

[0016] The present invention sets a cavity between the mounting plate and the rubber frame. When a falling object falls onto the rubber frame, the rubber frame is depressed downward. The impact force generated by the falling object diffuses to the surrounding area with the depressed area of ​​the rubber frame as a base point. The impact force generated by the falling object begins to weaken, and the damage to the mounting plate is further reduced.

[0017] The present invention adds a spring I in the cavity between the mounting plate and the rubber frame. When a falling object falls onto the rubber frame and the rubber frame is depressed downward, the impact force generated by the falling object is dispersed to the spring I around the depressed area of ​​the rubber frame, thereby increasing the degree of weakening of the impact force generated by the falling object. After the top surface of the rubber frame contacts the top surface of the mounting plate, the impact force exerted by the falling object on the mounting plate is further reduced, and the damage to the mounting plate is further reduced.

[0018] The present invention provides connecting plates in the rubber frame, and each connecting plate connects the springs I located in the same row as viewed from the front to the back as a whole. When a falling object falls onto the rubber frame and the rubber frame sags downward, the connecting plates around the sag area of ​​the rubber frame will follow and sink, and the springs I connected to the connecting plates will be contracted at the same time. More springs I will weaken the impact force of the falling object, and the mounting plate will be better protected.

[0019] The present invention adds a moving block to the mounting plate, and adds a rotating plate to the moving block. All the rotating plates replace the mounting plate and are fixedly connected to the springs I located in the same row from the front to the back. When the springs I are forced to contract, the rotating plates rotate toward the downwardly recessed area of ​​the rubber frame, the connecting plates deflect following the rotating plates, and the moving blocks move in the opposite direction of the rotating plates, so that the springs I face the downwardly recessed area of ​​the rubber frame. The springs I can better bear the impact force generated by the falling object, and the springs I are prevented from twisting, which affects the weakening of the impact force of the springs I on the falling object. The weakening effect of the springs I on the impact force of the falling object is improved.

[0020] The present invention improves the stability of the present invention by adding a buffer component in the support column I and adding a support column II between the bearing seat and the mounting plate. When the support column I contacts the gravel on the ground, the support column I slides toward the middle of the bearing seat. The support column I, the bearing seat and the mounting plate are set to be in sliding connection. The support column I slides toward the middle of the bearing seat. A buffer space is formed when the support column I slides on the bearing seat, and the damage to the support column I is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0029] Example 1

[0030] A protector for an electric device having multiple protection functions, such as Figure 1-Figure 5 As shown, it includes a bearing seat 1, a support column Ⅰ2, a mounting plate 3, a movable fixing plate 4 and a limit buckle 5; nine support columns Ⅰ2 are installed on the left side of the bearing seat 1, and the top of all the support columns Ⅰ2 is jointly installed with a mounting plate 3, and the bearing seat 1, all the support columns Ⅰ2 and the mounting plate 3 form a basic protection frame; two movable fixing plates 4 that are symmetrical on the left and right are slidably connected to the bearing seat 1; the bearing seat 1 and the mounting plate 3 are both installed with a limit buckle 5, and the limit buckle 5 is located in front of the movable fixing plate 4;

[0031] It also includes a rubber frame 6 and springs Ⅰ9; the rubber frame 6 is fixedly connected to the mounting plate 3, and a cavity is provided between the mounting plate 3 and the rubber frame 6; a plurality of springs Ⅰ9 distributed in a matrix are provided in the cavity between the mounting plate 3 and the rubber frame 6.

[0032] A positioning pin is provided on the limit buckle 5, and positioning holes are opened on the bearing seat 1 and the mounting plate 3. After the positioning pin of the limit buckle 5 is inserted into the positioning holes of the bearing seat 1 and the mounting plate 3, the top surface of the limit buckle 5 is flush with the top surface of the bearing seat 1 and the bottom surface of the mounting plate 3, which will not affect the normal use of the power device.

[0033] The rubber frame 6 is provided with an arc portion 6a, which facilitates guiding the falling object to the periphery.

[0034] A plurality of connecting plates 6b are provided in the rubber frame 6, and all the connecting plates 6b are fixedly connected to the springs Ⅰ9 located in the same row when viewed from the front to the back, connecting the springs Ⅰ9 located in the same row when viewed from the front to the back as a whole, so that when a falling object falls onto the rubber frame 6, more springs Ⅰ9 can be used.

[0035] It also includes a moving block 7 and a rotating plate 8; a plurality of moving blocks 7 are slidably connected to the front and rear sides of the mounting plate 3; all the front moving blocks 7 are rotatably connected to a rotating plate 8, and all the rotating plates 8 are rotatably connected to the corresponding rear moving blocks 7, all the rotating plates 8 replace the mounting plate 3 and are fixedly connected to the springs I9 located in the same column when viewed from the front to the back, and all the moving blocks 7 are provided with springs III 7a on the left and right sides.

[0036] The width of the rubber frame 6 is greater than the width of the protective frame. When the electric device and the present invention fall from the transport vehicle, the rubber frame 6 will contact the ground before the protective frame, thereby reducing damage to the protective frame.

[0037] In the present invention, for the convenience of description, the bearing seat 1, all the support columns Ⅰ2 and the mounting plate 3 form a basic protection frame which is described as the protection frame.

[0038] Before using the present invention, place the power device on the bearing seat 1. When pushing the power device onto the bearing seat 1, the power device presses the limit buckle 5, and the limit buckle 5 is pressed into the bearing seat 1 and the mounting plate 3. At this time, the power device is located between all the movable fixed plates 4. When the power device loses contact with the limit buckle 5, the pushing of the power device is stopped, and the limit buckle 5 pops out from the bearing seat 1 and the mounting plate 3. The limit buckle 5 fits with the power device, and the limit buckle 5 limits and fixes the power device. At this time, the door of the power device is blocked by the limit buckle 5, and the power device cannot be opened for parameter adjustment. Then, the movable fixed plate 4 is manually pushed toward the power device. When the power device fits with the movable fixed plate 4, bolts are manually used to tighten the movable fixed plate 4. The fixed plate 4 is fixed, so that the fixed plate 4 is moved to limit the side of the power device. Then the line is installed on the power device and the power device is started to be used. When the power device needs to be adjusted, the limiting buckle 5 positioning pin is inserted into the positioning hole of the bearing seat 1 and the mounting plate 3. The top surface of the limiting buckle 5 is flush with the top surface of the bearing seat 1 and the bottom surface of the mounting plate 3, which will not affect the adjustment of the parameters of the power device. It should be noted that after the adjustment of the parameters of the power device is completed, the limiting buckle 5 positioning pin needs to be pulled out from the positioning hole of the bearing seat 1 and the mounting plate 3, so that the limiting buckle 5 pops out from the bearing seat 1 and the mounting plate 3, so that the limiting buckle 5 fits with the power device during the time when the parameters of the power device are not adjusted, and the limiting buckle 5 limits and fixes the power device.

[0039] Considering that when the present invention is used on a construction site, there may be falling objects on the construction site. When the falling object falls on the power device, that is, after the falling object collides with the power device, the power device is easily damaged. At this time, after the power device is placed in the present invention, when the falling object falls on the power device, the falling object will fall on the protective frame and impact the protective frame, thereby protecting the power device. When the present invention protects the power device, the mounting plate 3 of the protective frame contacts the falling object many times, which may easily cause the mounting plate 3 of the protective frame to be damaged. Moreover, if the weight of the falling object is large, the impact on the mounting plate 3 may be If the impact is too large, the mounting plate 3 of the protective frame may be seriously damaged, affecting the protection of the electrical device and requiring replacement and repair. This is troublesome and increases the cost. At this time, a rubber frame 6 is added to the mounting plate 3. When the falling object falls on the protective frame, the falling object will fall on the rubber frame 6, impacting the rubber frame 6. The force generated by the impact of the falling object is directly applied to the mounting plate 3 and the rubber frame 6. The rubber frame 6 will weaken the impact of the falling object, reduce the force generated by the impact, and then the force is applied to the mounting plate 3 to reduce the damage to the mounting plate 3.

[0040] Considering that the impact force generated by the falling object is relatively large, after the impact of the falling object is weakened by the rubber frame 6, the mounting plate 3 will still be damaged. By setting a cavity between the mounting plate 3 and the rubber frame 6, when the falling object falls on the rubber frame 6, the rubber frame 6 is depressed downward, and the impact force generated by the falling object diffuses to the periphery with the depressed area of ​​the rubber frame 6 as the base point, and the impact force generated by the falling object begins to weaken. After the top surface of the rubber frame 6 contacts the top surface of the mounting plate 3, the impact force generated by the falling object will be applied to the mounting plate 3, and the mounting plate 3 will be damaged. The damage suffered is reduced again. In order to better protect the electronic device, a spring Ⅰ9 is added in the cavity between the mounting plate 3 and the rubber frame 6. When the falling object falls onto the rubber frame 6 and the rubber frame 6 is recessed downward, the impact force generated by the falling object will be dispersed to the spring Ⅰ9 around the recessed area of ​​the rubber frame 6, thereby increasing the degree of weakening of the impact force generated by the falling object. After the top surface of the rubber frame 6 contacts the top surface of the mounting plate 3, the impact force exerted by the falling object on the mounting plate 3 is further reduced, and the damage suffered by the mounting plate 3 is further reduced.

[0041] After the falling object falls onto the rubber frame 6, debris will remain on the rubber frame 6. When a subsequent falling object falls onto the rubber frame 6, the subsequent falling object squeezes the debris on the rubber frame 6, causing the rubber frame 6 to be damaged. At this time, by setting the top of the rubber frame 6 as an arc 6a, when the falling object falls onto the rubber frame 6, the falling object will fall on the arc 6a, and the impact force generated by the falling object will be transmitted to the periphery, causing the rubber frame 6 to vibrate, and the arc 6a will cooperate with the debris remaining on the rubber frame 6 to be guided to the periphery, thereby reducing the damage to the rubber frame 6.

[0042] Considering that when the falling object falls onto the rubber frame 6 and the rubber frame 6 sinks downward, only the springs Ⅰ9 in a circle around the downwardly sunken area of ​​the rubber frame 6 will be forced to contract, the utilization rate of the springs Ⅰ9 is low, and the weakening of the impact force of the falling object is limited. At this time, a connecting plate 6b is provided in the rubber frame 6, and each connecting plate 6b connects the springs Ⅰ9 located in the same column as seen from the front to the back as a whole. When the falling object falls onto the rubber frame 6 and the rubber frame 6 sinks downward, the connecting plates 6b around the downwardly sunken area of ​​the rubber frame 6 will follow and sink, and the springs Ⅰ9 connected to the connecting plates 6b will be forced to contract at the same time, more springs Ⅰ9 will weaken the impact force of the falling object, and the mounting plate 3 is better protected.

[0043] Taking into account that when spring Ⅰ9 weakens the impact force of a falling object, because the falling direction of the falling object is not parallel to spring Ⅰ9, after the falling object generates an impact force on spring Ⅰ9, spring Ⅰ9 will be twisted, affecting the weakening of the impact force of the falling object by spring Ⅰ9. In order to make spring Ⅰ9 better weaken the impact force of the falling object, a moving block 7 is added to the mounting plate 3, and a rotating plate 8 is added to the moving block 7. All the rotating plates 8 replace the mounting plate 3 and are fixedly connected to the springs Ⅰ9 located in the same column from front to back. When the spring Ⅰ9 is forced to contract, The rotating plate 8 rotates toward the downwardly recessed area of ​​the rubber frame 6, the connecting plate 6b deflects following the rotating plate 8, and the moving block 7 moves in the opposite direction to the flipping of the rotating plate 8, so that the spring I9 is ​​facing the downwardly recessed area of ​​the rubber frame 6. The spring I9 can better bear the impact force generated by the falling object, avoid twisting of the spring I9, and affect the weakening of the impact force of the falling object by the spring I9. The weakening effect of the impact force generated by the falling object by the spring I9 is ​​improved. By adding spring III7a on the left and right sides of the moving block 7, after the present invention stops flipping, the spring III7a drives the moving block 7 to reset.

[0044] It should be noted that during the transportation of the electric device, due to excessive road bumps, the fixation of the electric device may fail, the electric device may shake greatly, and the electric device may fall from the transport vehicle. Since the electric device is not protected, after the electric device falls from the transport vehicle, the electric device will be severely damaged or even directly scrapped, causing economic losses. After the electric device is placed in the present invention, if the electric device and the present invention fall from the transport vehicle, because the width of the rubber frame 6 is greater than the width of the protective frame, the rubber frame 6 will first contact the ground, thereby reducing the damage to the protective frame and better protecting the electric device.

[0045] Example 2

[0046] On the basis of Example 1, Figure 4-Figure 6 As shown, it also includes a buffer component; a buffer component is installed in all support columns Ⅰ2; the buffer component includes an airbag 101 and a support column Ⅱ102; four storage grooves are opened in all support columns Ⅰ2; the support column Ⅰ2 is slidably connected to the bearing seat 1 and the mounting plate 3; an airbag 101 is provided in all support column Ⅰ2 storage grooves; all support columns Ⅰ2 are provided with a support column Ⅱ102 on the side facing the center of the bearing seat 1, all support columns Ⅱ102 are fixedly connected to the bearing seat 1 and the mounting plate 3, all support columns Ⅱ102 are slidably connected to the corresponding support columns Ⅰ2, and four push plates 102a are provided at the connection between all support columns Ⅱ102 and support columns Ⅰ2, and all push plates 102a are located in the storage grooves of support columns Ⅰ2 and fit with the corresponding airbags 101.

[0047] It also includes a cylinder 103; a plurality of cylinders 103 are fixedly connected to one side of all the support columns I 2 away from the support column II 102.

[0048] The connection between the cylinder 103 and the support column Ⅰ2 is designed to be easily broken to avoid damage to the support column Ⅰ2.

[0049] It also includes a positioning component; all support columns Ⅰ2 and all support columns Ⅱ102 are jointly installed with three positioning components; the positioning component includes a T-shaped column 110, a positioning plate 111 and a spring Ⅱ112; a T-shaped column 110 is fixedly connected to the side of support column Ⅱ102 facing support column Ⅰ2, the T-shaped column 110 passes through support column Ⅰ2 and is located inside it, and the side of the T-shaped column 110 away from the middle of the bearing seat 1 is flush with the side of the support column Ⅰ2 away from the middle of the bearing seat 1; two positioning plates 111 are rotatably connected to the T-shaped column 110; a spring Ⅱ112 is fixedly connected between the T-shaped column 110 and all the positioning plates 111.

[0050] Because the transport vehicle is in a moving state, if the electric device and the present invention fall from the transport vehicle, after the top of the present invention contacts the ground, the electric device and the present invention will roll on the ground. During the rolling process, various parts of the protection frame are subjected to multiple impacts in a short period of time. Due to the large number of impacts, the support column Ⅰ2 will bend and break, resulting in a significant decrease in the protection capability of the present invention. At this time, a buffer component is added to the support column Ⅰ2, and the support column Ⅱ102 slides in the storage groove of the support column Ⅰ2 through the push plate 102a. First, the stability of the present invention is improved by adding a support column Ⅱ102 between the bearing seat 1 and the mounting plate 3. During the rolling process of the present invention, when the support column Ⅰ2 contacts the gravel on the ground, the support column Ⅰ2 collides with the gravel on the ground and is damaged. By setting the support column Ⅰ2, the bearing seat 1 and the mounting plate 3 to be in sliding connection, because the width of the rubber frame 6 is larger than the protection frame The width of the frame, the rubber frame 6 will first contact the ground. When the rubber frame 6 contacts the ground and the rubber frame 6 is squeezed and contracted, the support column Ⅰ2 is close to the ground. If there is gravel on the ground, the support column Ⅰ2 will first contact the gravel on the ground, and the gravel hits the support column Ⅰ2. At this time, the support column Ⅰ2 slides toward the middle of the bearing seat 1. When the support column Ⅰ2 slides on the bearing seat 1, a buffer space is formed, and the damage to the support column Ⅰ2 is reduced. When the support column Ⅰ2 slides toward the middle of the bearing seat 1, the space in the storage groove of the support column Ⅰ2 is reduced, and the push plate 102a squeezes the airbag 101. The airbag 101 is squeezed and expands outward from the storage groove of the support column Ⅰ2. When the present invention flips the expanded airbag 101 to contact the ground, the expanded airbag 101 replaces the support column Ⅰ2 to contact the ground, and the damage to the support column Ⅰ2 when it contacts the gravel on the ground is reduced again.

[0051] Considering that when the electric device and the present invention fall from the transport vehicle, the support column Ⅰ2 will come into contact with the gravel on the ground only after the rubber frame 6 is squeezed and contracted, so that the airbag 101 cannot quickly expand to replace the support column Ⅰ2 to contact the gravel on the ground, at this time, by adding a cylinder 103 to the support column Ⅰ2, before the support column Ⅰ2 contacts the ground, the cylinder 103 first contacts and collides with the ground, the cylinder 103 is squeezed, the support column Ⅰ2 quickly slides toward the middle of the bearing seat 1, and the push plate 102a quickly squeezes the airbag 101, so that the airbag 101 expands to replace the support column Ⅰ2 and contacts the ground The contact between cylinder 103 and support column Ⅰ2 is further reduced by the contact between cylinder 103 and support column Ⅰ2 and the gravel, and the damage caused by the contact between cylinder 103 and support column Ⅰ2 and the ground is further reduced. Meanwhile, considering that when cylinder 103 contacts the ground, cylinder 103 will transfer the impact force caused by the collision to support column Ⅰ2, causing damage to support column Ⅰ2, at this time, the connection between cylinder 103 and support column Ⅰ2 is set to be easy to break. After cylinder 103 is subjected to a certain impact force, the connection between cylinder 103 and support column Ⅰ2 will break, and cylinder 103 will detach from support column Ⅰ2. The impact force caused by the collision between cylinder 103 will not be transferred to support column Ⅰ2, thereby reducing the damage caused to support column Ⅰ2.

[0052] Considering that when the inflated airbag 101 contacts the ground, the inflated airbag 101 continues to be squeezed, and the inflated airbag 101 is released in the storage groove of the support column Ⅰ2, the squeezing force released by the airbag 101 pushes the push plate 102a, causing the inflated airbag 101 to retract into the storage groove of the support column Ⅰ2, resulting in the inflated airbag 101 being unable to effectively replace the support column Ⅰ2 to contact the ground, thereby reducing damage to the support column Ⅰ2. At this time, by adding a positioning assembly to the support column Ⅰ2 and the support column Ⅱ102, the initial spring Ⅱ112 is squeezed and is in a stressed contracted state. When the airbag 101 is first squeezed, the T-column 110, the positioning plate 111 and the spring Ⅱ112 are moved from the support column Ⅰ2 to the support column Ⅰ2. The spring Ⅱ112 is no longer squeezed, and the spring Ⅱ112 is reset to push the positioning plate 111, so that the positioning plate 111 is deployed on the T-shaped column 110, and the positioning plate 111 is stuck on the support column Ⅰ2, and the T-shaped column 110 cannot be retracted into the support column Ⅰ2. When the inflated airbag 101 is released in the storage groove of the support column Ⅰ2, the squeezing force released by the airbag 101 cannot push the push plate 102a due to the restriction of the positioning plate 111, so that the partially inflated airbag 101 located outside the storage groove of the support column Ⅰ2 continues to remain in an inflated state, and the inflated airbag 101 can effectively replace the support column Ⅰ2 in contact with the ground, and stably reduce the damage to the support column Ⅰ2.

[0053] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
