DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] The wall hole in this application mainly refers to the hole formed when the door frame or window frame is installed.

[0047] Example 1

[0048] Reference Figure 1 - Figure 7

[0049] This embodiment provides a safety belt hanging device, comprising:

[0050] A main body 1, wherein the main body 1 is a rod-shaped structure, has at least one anchoring point 11, and has a first supporting structure 2 at both ends;

[0051] The first supporting structure 2 protrudes from the side wall of the main body 1 and has a first supporting surface 21 for abutting against the inner wall of the wall hole; the first supporting surface 21 is flush with the end surface of the main body 1;

[0052] Wherein, at least the first supporting structure 2 at one end of the main body 1 has a pushing mechanism 3, and the pushing mechanism 3 at least includes:

[0053] A guiding hole 31 which penetrates through the first support structure 2 and has an axis parallel to the length direction of the main body 1;

[0054] An adjusting part 32 which is arranged in the guiding hole 31;

[0055] A second support structure 33 which is arranged at the end of the adjusting part 32 and protrudes from the first support surface 21;

[0056] Wherein, the end surface of the second support structure 33 is a second support surface 331 for abutting against the inner wall surface of the wall hole; the adjusting part 32 is in threaded connection with the guiding hole 31 to adjust the distance between the second support surface 331 and the first support surface 21.

[0057] In the prior art, for outdoor high-altitude operations, an expansion bolt is usually used to be arranged inside the wall to obtain an anchoring point 11. However, for some rooms that have been interiorly decorated, when performing high-altitude operations, the interior wall cannot be damaged. Usually, the safety belt is tied to furniture, but the weight of the furniture is limited and it is relatively easy to be dragged. At the same time, the structural strength of the bolted position of the furniture is not guaranteed either, and it is very likely to break, which is extremely dangerous. In view of this, this embodiment provides a hanging device that does not require wall damage to provide a reliable anchoring point 11 for the safety belt.

[0058] Specifically, a square tube profile is used as the main body 1. The square tube profile, as a hollow structure, is not heavy, and the side wall of the square tube itself is a good reinforcing rib, having better anti-bending strength than a round tube. In the square tube profile, an anchoring point 11 can be formed by welding a hanging ring for connecting the safety belt. Further, the hanging ring can be first sleeved on the outside of the main body 1 and then welded. Since the structural strength of the welding is relatively poor and improper welding is likely to cause breakage and lead to safety accidents, if the hanging ring has been sleeved on the main body 1 before welding, then the welding point is subjected to a squeezing force and is difficult to be damaged. And even in case of special circumstances where the welding point breaks, the hanging ring itself can abut against the side wall of the main body 1 to provide a secondary safety guarantee for the user and avoid accidents.

[0059] Both ends of the main body 1 are provided with first support structures 2 to form a U-shaped structure. The middle section of the U-shaped structure is the main body 1, and both sides are the first support structures 2. And at least one end of the first support structure 2 is provided with a pushing mechanism 3. Among them, for the pushing mechanism 3, the guiding hole 31 is specifically a threaded through hole passing through the first support surface 21, the adjusting part 32 is specifically a bolt longer than the width of the first support structure 2, the second support structure 33 is arranged at the end of the support part, and the end surface of the second support structure 33 is a second support surface 331. By rotating the adjusting part 32 in the guiding hole 31, the position of the second support structure 33 can be changed.

[0060] The first support surface 21 and the second support surface 331 are the main fixing components of the tie-down device in this embodiment, and the specific usage is as follows:

[0061] First, place the first support surface 21 and the second support surface 331 in the wall hole, and rotate the adjustment portion 32 to allow the second support surface 331 to continuously approach the inner wall surface of the wall hole until the first support surface 21 and the second support surface 331 are respectively pressed against two side surfaces of the wall hole;

[0062] Furthermore, the main body 1 may have a plurality of models of different lengths to adapt to wall holes of different sizes;

[0063] Furthermore, the first supporting structures 2 at both ends can be respectively provided with pushing mechanisms 3, and the two second supporting surfaces 331 can be used to abut against the inner wall surface of the wall hole, so that a larger adjustment range can be obtained.

[0064] Example 2

[0065] Also includes:

[0066] A third supporting structure 4, the third supporting structure 4 protrudes from the end surface of the main body 1 along the length direction of the main body 1 and is fixedly connected to the main body 1;

[0067] The third supporting structure 4 has a third supporting surface 41 ; the third supporting surface 41 intersects with the first supporting surface 21 to form a right-angle structure for abutting against the outer wall surface of the wall hole.

[0068] The adjusting part 32 of the embodiment 1 is a threaded transmission, which is a labor-saving transmission. When the user rotates the adjusting part 32 into place, it is easy to generate a huge friction between the supporting surface and the wall. However, this is a manual operation after all, and people have different judgments on whether it is rotated into place. In addition, high-altitude operations are very dangerous and accidents are not allowed.

[0069] In this regard, the present embodiment adds a third support structure 4, which is specifically an extension structure of the two ends of the main body 1 in the structure of embodiment 1. Specifically, it can be understood that the main body 1 with the third support structure 4 is a longer square tube profile than that without the third support structure 4, and the first support surface 21 is no longer flush with the end of the square tube profile, but has a distance, and the position passed by this distance is the third support structure 4.

[0070] A side wall surface of the third supporting structure 4 facing the first supporting structure 2 is a third supporting surface 41 , and the third supporting surface 41 intersects with the first supporting surface 21 to form a right-angle structure.

[0071] The wall parallel to the door is the outer wall of the wall hole.

[0072] When a special situation occurs on the second supporting surface 331, causing the hanging device to loosen, the third supporting surface 41 moves toward the outer wall of the wall hole until it abuts against the outer wall, providing secondary safety protection for the user.

[0073] During specific use, the tie-down device can be slightly raised above the ground. The above-mentioned loose tie-down device refers to the state in which the first support surface 21 and the second support surface 331 are completely ineffective, rather than the state in which the friction force is large enough to cause the sliding tie-down device to slide. The first support surface 21, the second support surface 331 and the third support surface 41 act together on the wall, and keeping the tie-down device stationary is actually a very good fixing method. However, after the third support surface 41 contacts the wall, it is not easy for us to judge whether the first support structure 2 has failed. If there is obvious shaking at this time (for example, the user stays on the outer wall and then uses the safety belt again), it is possible that the tie-down device will flip over, causing the first support structure 2 to fail, and then the user will shake in the air later, and the third support surface 41 will be out of contact with the wall. Therefore, the tie-down device is raised to a certain height. When the first support structure 2 fails, the tie-down device will instantly fall to the ground to remind the user.

[0074] Example 3

[0075] like Figure 1 and Figure 2 As shown, the main body 1 also includes:

[0076] A first rod 5, wherein the first rod 5 is connected to the first supporting structure 2 and the third supporting structure 4 at one end thereof and has a first fixing hole 51;

[0077] A second rod 6, the second rod 6 is connected to the first supporting structure 2 and the third supporting structure 4 at the other end thereof, and has a second fixing hole 61;

[0078] The first rod 5 and the second rod 6 have a displacement stroke, which is used to adjust the distance between the first support surfaces 21 at both ends of the main body 1 and the distance between the second support surfaces 331 at both ends of the main body 1;

[0079] A fixing pin 7 is passed through the first fixing hole 51 and the second fixing hole 61 to fix the distance between the first supporting surfaces 21 at two ends of the main body 1 .

[0080] Different types of hanging devices need to be replaced for wall holes of different sizes, which is very inconvenient. In this regard, this embodiment provides a hanging device that can adapt to wall holes of different sizes.

[0081] The main body 1 is composed of a first rod 5 and a second rod 6, and the first rod 5 and the second rod 6 have a displacement stroke to change the length of the main body 1. Specifically, the first rod 5 and the second rod 6 can also be square tube profiles, and the cross-sectional dimensions of the two are different. For example, the cross-sectional dimension of the first rod 5 is larger than the cross-sectional dimension of the second rod 6: the cross-sectional outer contour of the second rod 6 is greater than or equal to the cross-sectional inner contour of the first rod 5, and the first rod 5 is sleeved on the outside of the second rod 6, and the two are slidably connected. In addition, the first rod 5 has a plurality of first fixing holes 51, and the second rod 6 has at least one second fixing hole 61, and the spacing of the first fixing holes 51 is set to the difference between different common door opening sizes. It should be noted that the main body 1 shrunk to the minimum state should be smaller than the minimum size of the door opening so that the first support part can enter the door opening.

[0082] At the same time, after the first fixing hole 51 is concentrically aligned with the second fixing hole 61, the first rod 5 and the second rod 6 are fixedly connected by the fixing pin 7. The fixing pin 7 can specifically be a bolt with an outer diameter close to the first fixing hole 51. The bolt passes through the first fixing hole 51 and the second fixing hole 61, and the bolt head is pressed against the side wall of the first rod 5, and then tightened with a nut to press against the other pair of side surfaces.

[0083] The hanging device of this embodiment can not only use wall holes of different sizes, but also can be stored when not in use, so as to be easy to carry and transport.

[0084] Example 4

[0085] like Figure 3 As shown, the first supporting structure 2 has a mounting ring 22, and the mounting ring 22 is sleeved on the outside of the main body 1 so that the first supporting structure 2 is slidably connected to the main body 1, and is used to adjust the distance between the first supporting structures 2 at both ends of the main body 1;

[0086] The mounting ring 22 has a first fixing hole 51 ; the main body 1 has a plurality of second fixing holes 61 ; the first supporting structure 2 further has a fixing pin 7 ; the fixing pin 7 passes through the first fixing hole 51 and the second fixing hole 61 to fix the position of the first supporting structure 2 .

[0087] This embodiment provides another hanging device that can be used for wall holes of different sizes.

[0088] Specifically, the first support structure 2 has a mounting ring 22, which is sleeved on the outside of the main body 1, so that the first support structure 2 can change its position on the main body 1, thereby changing the distance between the two first support structures 2. At the same time, the mounting ring 22 has at least one first fixing hole 51, and the side wall of the main body 1 has a plurality of second fixing holes 61. The first fixing hole 51 is aligned with the second fixing hole 61 to determine the position of the first support member on the main body 1, and then the fixing pin 7 passes through the first fixing hole 51 and the second fixing hole 61 to achieve the fixation of the first support structure 2.

[0089] More specifically, the fixing pin 7 is a bolt, and the second fixing hole 61 is arranged on the upper and lower side walls of the main body 1, rather than parallel to the front and rear side walls of the third support surface 41. The bolt head of the fixing pin 7 abuts against the wall surface of the mounting ring 22, and the other end is clamped to the opposite side wall surface by a nut.

[0090] Example 5

[0091] like Figure 2 As shown, the pushing mechanism 3 also has a first locking member 34;

[0092] The first locking member 34 is disposed on the adjusting portion 32 and abuts against the supporting structure to lock the position of the adjusting portion 32 .

[0093] During use, it was found that the hanging device gradually loosened. This is because there is shaking during high-altitude operations, which will generate forces of different magnitudes on the main body 1. Therefore, different deformations will be generated on the main body 1, and then the second support surface 331 will change its angle with the wall, so that the abutting force is decomposed into different directions to drive the adjustment part 32 to rotate. Repeatedly, this will cause the angle of the adjustment part 32 to change. For the abutting force of this threaded connection, the actual pitch that generates the force is only a small pitch, so the adjustment part 32 only needs to rotate a small angle to cause looseness.

[0094] In this regard, the push mechanism 3 in this embodiment also has a first locking member 34. Specifically, after the adjustment portion 32 passes through the guide hole 31, the first locking member 34 is inserted into the adjustment portion 32, and then the second support structure 33 is installed. At this time, the first support structure 2 can actually be regarded as a nut, so the first locking member 34 and the first support structure 2 form a double-nut locking structure, which can prevent the adjustment portion 32 from loosening to a great extent, thereby preventing the hanging device from loosening and ensuring the safety of the user.

[0095] Example 6

[0096] The friction coefficient of the bottom surface of the connecting hole 8 is smaller than the friction coefficient of the second supporting surface 331;

[0097] Wherein, the second supporting structure 33 has a connecting hole 8;

[0098] The adjusting portion 32 is rotatably connected to the second supporting structure 33 , and an end surface thereof abuts against a bottom surface of the connecting hole 8 .

[0099] The hanging device can be fixed in the wall hole mainly by relying on the friction between the first support surface 21, the second support surface 331 and the inner wall surface of the wall hole. Therefore, the first support surface 21, the second support surface 331 and the third support surface 41 can all be set to rubber material with better anti-slip effect, and can also reduce damage to the wall.

[0100] However, the second support surface 331 of the second support structure 33 is relatively special. When the second support surface 331 approaches the wall, it is not only subjected to horizontal force, but also to force in the direction of rotation around the adjustment part 32. Therefore, when we rotate the adjustment part 32, we must not only overcome the support force of the wall on the second support surface 331, but also overcome the friction between the two. This results in the force we use to rotate the adjustment part 32 not completely producing the effect of increasing the friction between the second support surface 331 and the wall, but a part of it is wasted to overcome the friction. Whether it is rotated into place depends on the resistance we feel when rotating. The friction between the wall and the second support surface 331 is defined as M1;

[0101] Resistance = support + M1;

[0102] The supporting force of the wall on the second supporting surface 331 is equal to the pressure of the adjusting part 32 on the second supporting surface 331, and the greater the pressure, the greater the friction. Therefore, we need to minimize the influence of M1 on the resistance to maximize the force of the rotating adjusting part 32, transfer it into pressure, and increase M1.

[0103] Specifically, in this embodiment, the second support structure 33 is rotatably connected to the adjustment part 32, and the main body 1 of the second support structure 33 is made of metal (i.e., the surface of the connection hole 8 is a metal surface), and the second support surface 331 is made of rubber. The friction force generated by the rotation of the adjustment part 32 when it abuts against the metal material is much smaller than the friction force between the rubber material and the wall. The friction force between the end surface of the adjustment part 32 and the bottom surface of the connection hole is M2.

[0104] At this time, resistance = support + M2;

[0105] This can convert the force applied by the operator to rotate the adjusting portion 32 into pressure on the second supporting surface 331 to the greatest extent, thereby increasing the friction between the second supporting surface 331 and the wall.

[0106] Example 7

[0107] like Figure 4-7 shown.

[0108] The side wall surface of the connecting hole 8 is a plurality of elastic cantilevers 81, and the end surface of the elastic cantilever 81 has a first chamfer 82;

[0109] The second supporting structure 33 further comprises a threaded section 332 whose outer diameter is greater than the outer diameter of the elastic cantilever 81, and the threaded section 332 comprises an external thread;

[0110] The pushing mechanism 3 further includes a second locking member 9, wherein the second locking member 9 has a first channel 91 and a second channel 92 which are connected to each other;

[0111] The first channel 91 has a diameter greater than that of the second channel 92 and has an internal thread that matches the external thread;

[0112] The second channel 92 has a diameter smaller than the outer diameter of the elastic cantilever 81 and has a second chamfer 921;

[0113] The second chamfer 921 is disposed on the connection surface between the first channel 91 and the second channel 92;

[0114] The second chamfer 921 abuts against the first chamfer 82 to allow the elastic cantilever 81 to contract radially.

[0115] After the hanging device is fixed to the wall, the adjusting part 32 needs to be fixedly connected with the second supporting structure 33, otherwise, the hanging device is easy to shake (because the second supporting structure 33 is rotatably connected with the adjusting part 32, there must be a certain gap, which provides room for shaking. At this time, whether the hanging device can shake depends on the size of M2 rather than the size of M1), and it is difficult for users to judge the specific situation. Therefore, in this embodiment, after the second supporting surface 331 abuts against the wall, during the movement of the second locking member 9 along the axial direction, the axial direction of the force is partially converted into the radial direction through the inclined surface, so that the elastic cantilever 81 can continuously hold the adjusting part 32.

[0116] like Figure 6 As shown, specifically, the second locking member 9 is configured as a nut structure, one end of the threaded hole is smaller than the diameter of the other end, the threaded hole is the first channel 91, the small diameter end is the second channel 92, and the inner end surface of the second channel 92 is also chamfered to form a second inclined chamfer 921. The second locking member 9 is rotated and the second locking member 9 is continuously approached to the second supporting surface 331 along the axis. During this process, the second inclined chamfer 921 will continuously squeeze the first inclined chamfer 82 of the elastic cantilever 81, so that the elastic cantilever 81 clamps the adjustment part 32. At the same time, the second locking member 9 is a ring-shaped structure that is difficult to deform, and squeezing the elastic cantilever 81 on the outside can prevent the elastic cantilever 81 from deforming.

[0117] Example 8

[0118] The main body 1 has two anchoring points 11 , and the two anchoring points 11 are symmetrically arranged on the main body 1 .

[0119] The main body 1 is a long rod structure and is stressed at both ends. At this time, the closer the anchor point 11 is to the middle section of the main body 1, the easier it is for the main body 1 to bend and deform. Severe deformation will first affect the smoothness of adjusting the spacing of the second support parts; secondly, when the main body 1 bends, the second support surface 331 will swing, increasing the pressure on the wall. The pressure acts at the edge of the second action surface, which is a distance away from the axis of the adjustment part 32. Therefore, this pressure is likely to cause the adjustment part 32 to bend. The bending of the adjustment part 32 as a bolt structure directly means that it cannot be used anymore; or the connection hole 8 of the second support structure 33 is damaged, so that the opening of the connection hole 8 is enlarged, causing the second support structure 33 to fall off easily.

[0120] By distributing the anchoring points 11 at both ends of the main body 1, the stress is distributed between the two anchoring points instead of being concentrated in the center. This can effectively prevent the main body 1 from bending. At the same time, the main body 1 does not need to increase the material thickness or additional reinforcement structure, thus ensuring the portability of the device to the greatest extent.

[0121] Furthermore, the main body 1 has an anchoring hole and an anchoring pin 111 . The anchoring pin 111 is disposed in the anchoring hole, and both ends of the anchoring pin 111 protrude from the anchoring hole to form the anchoring point 11 .

[0122] In order to withstand the tension of the safety belt, the wall thickness of the square tube profile of the main body 1 does not need to be very thick, and a too thick square tube profile is too heavy and not easy to carry. As a high-altitude working tool for renovated houses, the hooking device of the present application requires the user to bring the tool into the home of the service customer before use. If the tool is too heavy, it will obviously reduce the user's willingness to use this product. For thinner materials, the material is easily deformed during the welding process, so the welding is more difficult. If you want to avoid deformation, the strength of the welding is difficult to guarantee.

[0123] The anchor pin 111 can be set as a bolt structure, through which the bolt passes through the side wall of the main body 1, and the other end of the anchor pin 111 is locked with a nut. The buckle of the safety belt can be directly connected to the anchor pin 111.

[0124] Similarly, the anchor pin 111 can also be connected by welding, which requires first reserving a welding hole (anchor hole) in the main body 1, and then inserting the anchor pin 111 into the welding hole, while the two ends of the anchor pin 111 protrude from the welding hole, and finally welding. At this time, even if a special situation occurs and causes the welding position to break, the anchor pin 111 can provide secondary safety protection for the user by abutting the anchor hole with its side wall.
