Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-7 As shown, this utility model is a protective device for reserved holes in building construction, including a first adjusting rod 1, and further including: a second adjusting rod 2 distributed on one side of the first adjusting rod 1, and a snap-fit ​​rod 3 distributed on the side of the second adjusting rod 2 away from the first adjusting rod 1; an adjusting structure is provided on the inner side of the first adjusting rod 1; a cross-shaped locking seat 10 is provided on one side of the top of the first adjusting rod 1; a snap-fit ​​block 11 is provided on the side wall of the first adjusting rod 1; a snap-fit ​​groove 12 is provided on the side wall of the snap-fit ​​rod 3; a magnetic strip 13 is provided on the side wall of the first adjusting rod 1 near another independent first adjusting rod 1; a first vertical rod 14 is distributed above the first adjusting rod 1, and a second vertical rod 15 is distributed above the first vertical rod 14;

[0027] During operation, since a second adjusting rod 2 is provided on one side of the first adjusting rod 1, and an extension rod 6 is slidably sleeved between the first adjusting rod 1 and the second adjusting rod 2, and the first adjusting rod 1 and the second adjusting rod 2 have the same external dimensions, the distance between the first adjusting rod 1 and the second adjusting rod 2 can be adjusted by sliding the first adjusting rod 1 and the second adjusting rod 2 outward along the extension rod 6. Since a locking block 11 is fixedly provided at the end of both the first adjusting rod 1 and the second adjusting rod 2, and a locking rod 3 is provided on one side of the first adjusting rod 1, with the locking rod 3 perpendicular to the first adjusting rod 1, and since a locking groove 12 matching the size of the locking block 11 is opened on the end face of the locking rod 3, the locking block 11 fixed on the end face of the first adjusting rod 1 and the second adjusting rod 2 is inserted into the locking groove. The first adjusting rod 1 and the locking rod 3 can be combined to form an L-shape in the locking groove 12 on the end face of the rod 3. As shown above, the first adjusting rod 1 and the locking rod 3 are combined into a rectangular frame structure around the hole by two sets of first adjusting rods 1 and two sets of locking rods 3. Since a cross-shaped locking seat 10 is fixed at the top of the first adjusting rod 1 and the locking rod 3, and a first vertical rod 14 connected to the cross-shaped locking seat 10 is provided above the first adjusting rod 1, and a cross groove 16 adapted to the cross-shaped locking seat 10 is opened at the bottom of the first vertical rod 14, multiple sets of first vertical rods 14 can be inserted longitudinally along the groove of the cross groove 16 to the outside of the cross-shaped locking seat 10 to form a protective structure of a certain height above the first adjusting rod 1 and the locking rod 3.

[0028] The adjustment structure includes a storage groove 4, a positioning hole 5, an extension rod 6, a return spring 7, a positioning rod 8, and an auxiliary sliding plate 9. The storage groove 4 is opened inside the first adjustment rod 1. The front surface of the first adjustment rod 1 is provided with a positioning hole 5. The inner cavity of the storage groove 4 is provided with an extension rod 6. The inner side of one end of the extension rod 6 is fixedly connected to a return spring 7. The other end of the return spring 7 is fixedly connected to a positioning rod 8. The outer side of one end of the positioning rod 8 is fitted with an auxiliary sliding plate 9.

[0029] During operation, when it is necessary to adjust the distance between the two adjusting rods, pull the second adjusting rod 2 or the first adjusting rod 1 to make the adjusting rod slide along the extension rod 6. After the distance between the two adjusting rods is adjusted, release the pressure applied to the positioning rod 8. When the positioning rod 8 retracts to the inside of one end of the extension rod 6, it will squeeze the return spring 7, causing the return spring 7 to deform. Then, the reverse force generated by the deformation of the return spring 7 can be used to push the positioning rod 8 in the opposite direction, thereby inserting one end of the positioning rod 8 into the inside of the positioning hole 5, thus realizing the connection between the adjusting rod and the extension rod 6. The auxiliary sliding plate 9 is used to improve the stability of the adjusting rod during the lateral movement.

[0030] The bottom of the first vertical rod 14 is provided with a cross groove 16, the top of the first vertical rod 14 is provided with a threaded groove 17, the outer surface of the first vertical rod 14 is provided with a retaining rail 18, the bottom of the second vertical rod 15 is provided with a threaded joint 19, the inner side of the retaining rail 18 is engaged with a retaining strip 20, and a winding frame 21 is distributed on the side of the retaining strip 20 away from the retaining rail 18, and a net 22 is connected to the other side of the winding frame 21.

[0031] During operation, the spacing between multiple adjusting rods is pre-adjusted. Once the spacing is adjusted, the second vertical rod 15 moves the threaded connector 19 at its bottom, inserting the threaded connector 19 into the inner side of the threaded groove 17. Then, the second vertical rod 15 is rotated, and the threaded connection between the threaded connector 19 and the threaded groove 17 connects the second vertical rod 15 to the first vertical rod 14. After the connection is complete, the first vertical rod 14 is engaged with the top of the first adjusting rod 1 through the cross groove 16 at its bottom. At this point, the first vertical rod 14, after being spliced ​​on both sides... 4 are respectively engaged on one side of the top of the first adjusting rod 1 and the second adjusting rod 2. Then, the locking strip 20 is engaged and connected to the inner side of the locking rail 18, and the barrier net 22 is pulled. Since the barrier net 22 and the winding frame 21 are movably connected, that is, the inner side of the winding frame 21 is provided with a winding structure for the barrier net 22, the barrier net 22 can be extended when the locking strip 20 on the other side drives the winding frame 21 to pull the barrier net 22. After the barrier net 22 is extended, the winding frame 21 on the other side is engaged and connected to the locking rail 18 provided on the surface of the other first vertical rod 14 by another locking strip 20.

[0032] A fixed base 23 is fixedly installed on one end of the first adjusting rod 1, and a motor 24 is installed on the side wall of the fixed base 23. The output end of the motor 24 is connected to a winding roller 25, and a protective net 26 is sleeved on the outer surface of the winding roller 25. A baffle 27 is connected to the other end of the protective net 26, and an iron block 28 is provided on the side of the baffle 27 away from the protective net 26.

[0033] During operation, after all the adjustment rods and locking rods 3 are connected, the motor 24 operates, causing the winding roller 25 connected to its output end to rotate. The rotation of the winding roller 25 is used to retract and extend the protective net 26. When the protective net 26 is extended, the stop bar 27 is pulled. At this time, the stop bar 27 drives the iron block 28 to move. When the iron block 28 is close to the magnetic strip 13, the magnetic force of the magnetic strip 13 will attract the iron block 28 to one end surface of another first adjustment rod 1, thereby extending the protective net 26.

[0034] The positioning rod 8 is slidably connected to the extension rod 6 via the return spring 7, and the positioning rod 8 is symmetrically distributed along the vertical center line of the extension rod 6;

[0035] During operation, the reverse force generated by the deformation of the return spring 7 will push the positioning rod 8, thereby inserting one end of the positioning rod 8 into the inside of the positioning hole 5 to achieve the positioning of the extension rod 6.

[0036] The second vertical rod 15 is threadedly connected to the first vertical rod 14 through the threaded joint 19 provided at its bottom, and the cross groove 16 and the first vertical rod 14 form an integrated structure.

[0037] During operation, the second vertical rod 15 is threaded into the threaded groove 17 at the top of the first vertical rod 14 via the threaded connector 19 at its bottom, thereby achieving a threaded connection between the first vertical rod 14 and the second vertical rod 15.

[0038] Working principle: In use, first pull the second adjusting rod 2 or the first adjusting rod 1 to slide the adjusting rod along the extension rod 6. After the distance between the two adjusting rods is adjusted, release the pressure applied to the positioning rod 8. When the positioning rod 8 retracts to the inside of one end of the extension rod 6, it will compress the return spring 7, causing the return spring 7 to deform. The reverse force generated by the deformation of the return spring 7 can then push the positioning rod 8 in the opposite direction, thus inserting one end of the positioning rod 8 into the inside of the positioning hole 5, thereby connecting the adjusting rod and the extension rod 6. The auxiliary sliding plate 9 is used to improve the stability of the adjusting rod during lateral movement. After the distance between the adjusting rods is adjusted, adjust the... in the same way. After the spacing between the multiple locking rods 3 is adjusted, and since locking blocks 11 are fixed at the ends of both the first adjusting rod 1 and the second adjusting rod 2, and locking rods 3 are set on one side of the first adjusting rod 1, with the locking rods 3 perpendicular to the first adjusting rod 1, and since the end face of the locking rod 3 has a locking groove 12 that matches the size of the locking block 11, the locking blocks 11 fixed at the end faces of the first adjusting rod 1 and the second adjusting rod 2 are inserted into the locking groove 12 on the end face of the locking rod 3, so that the first adjusting rod 1 and the locking rod 3 can be combined to form an L-shape. As shown above, through two sets of first adjusting rods 1 and two sets of locking rods 3, the first adjusting rods 1 and the locking rods 3 are combined to form a rectangular frame structure surrounding the periphery of the hole. Both the adjusting rod 1 and the snap-fit ​​rod 3 have a cross-shaped retaining seat 10 fixed to their tops. A first vertical rod 14, connected to the cross-shaped retaining seat 10, is located above the first adjusting rod 1. The bottom of the first vertical rod 14 has a cross-shaped groove 16 that fits into the cross-shaped retaining seat 10. Therefore, by inserting multiple sets of first vertical rods 14 longitudinally along the groove of the cross-shaped groove 16 to the outside of the cross-shaped retaining seat 10, a protective structure of a certain height can be formed above the first adjusting rod 1 and the snap-fit ​​rod 3. Once multiple rods are connected, preliminary protection of the hole can be achieved. Then, the second vertical rod 15 drives the threaded connector 19 at its bottom to move, inserting the threaded connector 19 into the inner side of the threaded groove 17. At this time, rotating the second vertical rod 15... The connection between the second vertical rod 15 and the first vertical rod 14 is achieved through the threaded connection between the threaded connector 19 and the threaded groove 17. After the connection is completed, the first vertical rod 14 is engaged with the top of the first adjusting rod 1 through the cross groove 16 at the bottom. At this time, the first vertical rod 14, after being spliced ​​on both sides, is engaged with the top of the first adjusting rod 1 and the second adjusting rod 2 respectively. Then, the locking strip 20 is engaged with the inner side of the locking rail 18, and the barrier net 22 is pulled. Since the barrier net 22 and the winding frame 21 are movably connected, that is, the inner side of the winding frame 21 is provided with a winding structure for the barrier net 22, the barrier net 22 can be extended when the locking strip 20 on the other side drives the winding frame 21 to pull the barrier net 22.After the netting 22 is extended, the other side's winding frame 21 is engaged with the guide rail 18 on the surface of the other first vertical rod 14 via another locking strip 20. Finally, after all the adjusting rods and locking rods 3 are connected, the motor 24 operates, causing the winding roller 25 connected to its output end to rotate. The rotation of the winding roller 25 then controls the winding and unwinding of the protective netting 26. When the protective netting 26 is extended, the stop bar 27 is pulled, causing the iron block 28 to move. When the iron block 28 approaches the magnetic strip 13, the magnetic force of the magnetic strip 13 attracts the iron block 28 to one end of the other first adjusting rod 1, thus extending the protective netting 26.

[0039] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
