[0003] In the prior art Figure 1 As shown, the tail of a common foot (pedal) spike is provided with a long thread, and two nuts are provided on the foot spike. The foot spike passes through the mounting hole on the angle steel, and the two nuts are respectively located on the left and right sides of the angle steel. The foot spike can be installed by tightening the nuts; however, there are such shortcomings: since only the tail of the foot spike is limited and fixed, and the part where the foot spike extends is suspended, thus forming a cantilever beam structure, the connection between the foot spike and the angle steel is a weak point. At the same time, since the connection of the foot spike is provided with a thread and is relatively thin, it is also the weak point of the foot spike itself, and the foot spike is prone to breakage or bending at the weak point under the action of stress, posing a safety hazard. Therefore, how to improve the existing foot spikes to overcome the above problems is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0025] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0028] One of the preferred embodiments of the present application is as follows: Figures 1 to 7 As shown, an anti-fall hanging point type foot spike includes a foot spike body 1 and a support member 2. The support member 2 is installed on the foot spike body 1 and cooperates with the foot spike body 1 to form a support area. The weak point of the foot spike body 1 is located within the support area.

[0029] It is understandable that if Figure 1 and Figure 4As shown, we can take the example of the foot nail body 1 being installed on the fixing member 9 for explanation. In this case, the foot nail body 1 can be installed on the fixing member 9 through multiple nuts 3, and a weak point is formed between the threaded section of the first end (left end) of the foot nail body 1 and the rightmost nut 3, which is set as point A; and a support area is formed between the foot nail body 1 and the supporting member 2, and point A is located within the support area. It should be noted that the structure of the fixing member 9 here is not specifically limited, and can be, for example, the angle steel 6 of the transmission tower, a wall, a ladder, etc.

[0030] Furthermore, it can be understood as follows: the radial projection of the support area toward the foot spike body 1 forms a projection area, and we assume that this projection area is a line segment BC, and point A is located within BC; therefore, under the action of the support member 2, the external force on the foot spike body 1 can be offset or transferred accordingly, thereby preventing the foot spike body 1 from further deformation, greatly improving its service life and safety. This design not only ensures the stability of the foot spike body 1, but also reduces the risk of damage caused by external forces. Through the action of the support member 2, the foot spike body 1 can withstand pressure more effectively, extending its durability during use.

[0031] It should be known that, assuming that the weak point on the foot nail body 1 is located outside the projection range of the support area on the foot nail body 1, for example, the support member 2 is fixed at the right side of the weak point A, then at this time, the support member 2 is in a suspended state like the free end of the foot nail body 1, so it cannot play a supporting role for the weak point A of the foot nail body 1.

[0032] In this embodiment, there are multiple ways to install the support member 2, including but not limited to the following three:

[0033] Method 1 (such as Figure 7 As shown in a): the first end of the support member 2 is installed on the foot nail body 1, and the second end of the support member 2 can support the foot nail body 1. For example, the second end of the support member 2 can support and cooperate with the middle position or the second end of the foot nail body 1, so that a support area is formed on the foot nail body 1 between the first end and the second end of the support member 2.

[0034] Method 2 (such as Figure 6As shown in the figure): the foot spike body 1 is installed on the fixing member 9 through the first end, and the support member 2 can be matched with the fixing member 9. It can be understood that: the support member 2 is installed on the foot spike body 1 through the second end, and the installation position is spaced from the first end of the foot spike body 1, for example, the second end of the support member 2 is installed at the middle part or the second end of the foot spike body 1; and the first end of the support member 2 and the fixing member 9 are matched with each other, and the matching mode can be: the first end of the support member 2 and the fixing member 9 are only contact-typed, or the two are fixedly matched, such as welding or bolted connection. At this time, a support area is formed between the foot spike body 1, the support member 2 and the fixing member 9.

[0035] Method 3 (such as Figure 5 As shown): Both ends of the support member 2 are mounted on the foot spike body 1 so that the two ends of the support member 2 form a support area on the foot spike body 1.

[0036] It should be noted that, for Method 1 and Method 2, actually one end of the support member 2 is connected to the foot nail body 1, while Method 3 is that both ends of the support member 2 are connected to the foot nail body 1, so it has better stability, and thus the installation form of Method 3 is preferably adopted. Therefore, the specific embodiments below also take Method 3 as an example for detailed description.

[0037] One of the embodiments of the present application is as follows: Figure 5 As shown, when method three is adopted, the first end of the support member 2 must be connected to the first end of the foot nail body 1, and the second end of the support member 2 can be connected to any position of the foot nail body 1 as long as it is away from the weak point. However, considering that the middle position of the foot nail body 1 needs to be stepped on, in order not to affect or interfere with climbing, the second end of the support member 2 is preferably connected to the second end of the foot nail body 1.

[0038] Based on the above embodiment, a closed area is formed between the support member 2 and the foot nail body 1. Figure 4 As shown, the support member 2 can also be used as a gripping portion, that is, the climber's hands can grip the support member 2 very well, thereby ensuring stability during climbing; it should be noted that originally the climber would grip the foot spike body 1, and since the foot spike body 1 may leave dirt and mud after being stepped on, this will contaminate the climber's hands and may also cause the grip to slip. In addition, the anti-slip grooves on the outside of the foot spike body 1 may also hurt the hands.

[0039] On the other hand, the closed area can also facilitate the cooperation of the climber's safety rope, that is, the buckle at one end of the safety rope can be easily cooperated with the support member 2. Since the support member 2 and the foot nail body 1 are a closed structure, the buckle at one end of the safety rope can cooperate with them to prevent unhooking, thereby ensuring the safety of climbing the tower and preventing the staff from falling. Of course, the climber can also hang some objects when operating.

[0040] In one embodiment of the present application, the shape of the support member 2 also has various forms, for example, the support member 2 is an arc-shaped structure, or the support member 2 and the foot nail body 1 form a polygonal structure.

[0041] For example, Figure 5 As shown, the support member 2 and the foot nail body 1 can form a triangular structure; Figure 7 As shown in (a), the support member 2 is arc-shaped; Figure 7 As shown in (b) , the support member 2 and the foot nail body 1 can form a rectangular structure.

[0042] Based on the above embodiments, one of the embodiments of the present application is as follows: Figure 4 As shown, the support member 2 includes a first support portion 201 and a second support portion 202. The upper end of the first support portion 201 is the first end of the support member 2. The second support portion 202 can connect the first support portion 201 with the second end of the support member 2. Figure 4 As shown by the dotted line in FIG. 1 , that is, a triangular structure is formed between the first supporting portion 201 , the second supporting portion 202 and the foot nail body 1 .

[0043] Of course Figure 4 As shown by the dotted line in the figure, when the first support portion 201, the second support portion 202 and the foot nail body 1 are a non-right-angled triangular structure, the first support portion 201 and the foot nail body 1 can be considered to be in "point" contact cooperation. Therefore, when the foot nail body 1 is subjected to external force, the deformation of the foot nail body 1 is completely prevented by the strength of the first support portion 201 and the second support portion 202 themselves, so the stability is not unreliable.

[0044] In order to further improve the stability and safety of the support member 2, the support member 2 can cooperate with the fixing member 9 to further improve the support effect. Specifically, the first support portion 201 can be matched with the fixing member 9. At this time, the fixing member 9 can provide a supporting force to the support member 2, thereby preventing the support member 2 from further deformation, greatly improving the support effect of the foot nail body 1. Figure 4 As shown, the support member 2 does not abut against the fixing member 9; Figure 5As shown, at this time, the support member 2 and the fixing member 9 are offset against each other; it can be clearly seen from the two figures that the stability will be better when the support member 2 and the fixing member 9 are offset against each other.

[0045] It is understandable that: Figure 5 As shown, the first support portion 201 can adopt a structure parallel to the fixing member 9, so that the first support portion 201 and the fixing member 9 are completely counter-fitted with each other. When the support member 2 is subjected to an external force from the foot nail body 1, the fixing member 9 can also support the external force, thereby preventing the first support portion 201 from further deformation, thereby ensuring the stability and durability of the support member 2.

[0046] like Figure 5 As shown by the dotted line in , if the second support portion 202 is also a linearly inclined structure, the second support portion 202 and the second end of the foot nail body 1 can also be regarded as a "point" type connection structure. Therefore, when the foot nail body 1 is subjected to external force, it is mainly the vertical component of force, and the second support portion 202 cannot play a positive supporting role for this force. This will have a certain impact on the stability of the connection point between the upper end of the second support portion 202 (the second end of the support member 2) and the foot nail body 1, and thus the overall stability and service life of the support member 2 will be affected to a certain extent.

[0047] Therefore, in order to solve the above technical problems, one of the embodiments of the present application is as follows: Figure 5 As shown, the second supporting portion 202 includes a first connecting segment 2021 and a second connecting segment 2022 connected to each other. The first connecting segment 2021 is installed on the foot spike body 1 and is perpendicular to the axial direction of the foot spike body 1 , and the second connecting segment 2022 is connected to the first supporting portion 201 .

[0048] It can be seen that when the support member 2 is mainly subjected to the vertical component of the foot nail body 1 at this time, although it may be said that the overall force exerted on the second support part 202 remains unchanged, since the first connecting section 2021 and the foot nail body 1 are vertically arranged, the strength of the connection point between the second support part 202 and the foot nail body 1 will be more reliable, and the connection point between the two will not easily break.

[0049] One of the embodiments of the present application is as follows: Figure 2 As shown, in order to facilitate the installation of the support member 2, and without the need for additional processing and punching of the foot nail body 1 and the fixing member 9 during installation, and without the need for additional installation parts, the support member 2 can be installed on the foot nail body 1 in a sleeve-type manner; for example, discs 4 can be provided at both ends of the support member 2, and of course the disc 4 has a sleeve-type hole 8 that is compatible with the foot nail body 1.

[0050] Specifically, the discs 4 at both ends of the support member 2 are both sleeved on the foot nail body 1, and the disc 4 corresponding to the first end of the support member 2 is located at the threaded section of the first end of the foot nail body 1. Then, during installation, the support member 2 can be installed by tightening the nut 3 at the right end. That is to say, the installation of the foot nail body 1 and the installation of the support member 2 are carried out simultaneously, which can greatly improve the installation efficiency of the support member 2 and the installation method is also very simple.

[0051] It should be noted that the support member 2 can actually be installed on the foot nail body 1 by a fixed connection method such as welding, that is, the support member 2 has been installed before the foot nail body 1 is installed; or the support member 2 is installed after the foot nail body 1 is installed.

[0052] One of the embodiments of the present application is as follows: Figure 2 As shown, the support member 2 can adopt an integrally formed structure. For example, the initial material of the support member 2 can be a metal bar. The two ends of the metal bar can be firstly subjected to a stamping and punching integration process to form a disc 4 with a socket hole 8, and then the two positions of the metal bar are bent to form a first support portion 201, a second connecting segment 2022 and a first connecting segment 2021. However, in order not to affect the bending and cause damage to the self-strength of the support member 2, an arc transition can be adopted at the bending point between the first support portion 201 and the second support portion 202, and an arc transition can be adopted at the bending point between the first connecting segment 2021 and the second connecting segment 2022. Moreover, the arc structure can effectively alleviate stress concentration, enhance the bearing capacity and stability of the support member 2, thereby improving the safety and reliability of the entire structure.

[0053] However, the support member 2 may have the following disadvantages when the sleeve-type installation method is adopted: Figure 3 As shown, the fixing point of the support member 2 is completely limited by the extrusion fit of the left nut 3 and the left disc 4, and the threaded installation method also determines that the foot nail body 1 adopts a cylindrical structure as a whole. When the support member 2 is subjected to external force, such as the gripping force of the hand or the traction force of the safety rope, when the external force is greater than the limiting force of the nut 3, the support member 2 may rotate in a circle along the foot nail body 1, which will affect its stability.

[0054] Therefore, in order to solve the above-mentioned problem, one of the embodiments of the present application is as follows: Figure 2 As shown, the second end cross section of the foot nail body 1 is a non-circular structure, and the second end sleeve hole 8 of the support member 2 is adapted thereto.

[0055] For example, Figure 2As shown, assuming that the second end of the foot nail body 1 is a regular polygon block 7, and the sleeve hole 8 is also a regular polygon structure that matches the regular polygon block 7, when the two cooperate with each other, the support member 2 can be limited in the circumferential direction. Of course, the non-circular structure can also be a triangle, rectangle, etc. structure, and those skilled in the art can set it according to actual conditions.

[0056] The working principle of the utility model is as follows: we take the installation of the foot nail body 1 on the angle steel 6 of the transmission tower through the nut 3 as an example for explanation. First, the disc 4 on the right side of the support member 2 is sleeved on the outer side of the foot nail body 1, and then a nut 3 is screwed on the threaded section of the first end of the foot nail body 1, and then the disc 4 on the left side of the support member 2 is sleeved on the threaded section of the first end of the foot nail body 1 until it abuts against the above-mentioned nut 3, and at this time, the disc 4 on the right side will also be limited in the circumferential direction under the action of the regular polygon block 7, and the disc 4 on the left side of the support member 2 can itself form a gasket structure; finally, the threaded section of the foot nail body 1 with the support member 2 is passed through the angle steel 6, and a gasket 5 is sleeved to abut against the side of the angle steel 6, and then a nut 3 is tightened on the left end of the foot nail body 1 to complete the installation.

[0057] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
