Description

Technical Field

[0001] The utility model relates to the technical field of construction protection, in particular to a steel bar end protection tool. Background Art

[0002] Steel bars are widely used in various building structures. Workers are often accidentally hit or scratched by the exposed ends of steel bars during construction, which can easily lead to tetanus and other diseases.

[0003] In the prior art, a protective cap is usually installed on the end of the steel bar to protect the end of the steel bar. However, when installing the protective cap in the prior art, the protective cap is usually installed by setting a thread in the protective cap and screwing the protective cap to the end of the steel bar to achieve installation protection. The process of rotating and screwing the protective cap to install or remove it takes a long time.

[0004] Alternatively, an elastic ring is set in the protective cap, and the protective cap is clamped on the end of the steel bar through the elastic ring. However, when the end of the steel bar passes through the elastic ring, a large force is needed to press the protective cap for installation. In summary, the existing protective cap is not convenient for quick and convenient installation, which affects the construction efficiency. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a steel bar end protection tool to solve the technical problem in the prior art that the protective cap is not easy to install quickly and conveniently, thereby affecting the construction efficiency.

[0006] The utility model is realized by the following technical solutions:

[0007] A steel bar end protection tool comprises a protective cap made of elastic material, wherein the protective cap is in a cone-shaped structure as a whole, and the diameter of the opening end of the protective cap is the largest;

[0008] The open end of the protective cap is provided with a plurality of through slots along its axial direction, and the through slots radially penetrate the protective cap, and the open end of the protective cap is fixedly connected with a plurality of clips, and each of the clips is located on the inner wall between two adjacent through slots;

[0009] The inner wall of the protective cap is slidably connected with a propping piece for propping the clips outward to open the open end of the protective cap. The plurality of clips can be clamped and fixed on the end of the steel bar under the force generated by the deformation of the protective cap.

[0010] Furthermore, the support member is in the shape of a circular ring, and a plurality of paddles are arranged on the outer circumferential surface of the support member, and the free ends of the paddles extend outward through the through slots.

[0011] Furthermore, the toggle plate is T-shaped, and includes a connecting portion fixedly connected to the propping member, and a toggle portion integrally formed with the connecting portion, the width of the toggle portion is greater than the width of the connecting portion, and an avoidance distance is left between the toggle portion and the outer wall of the protective cap.

[0012] Furthermore, an outer circumferential surface of the expansion member is provided with an inclined surface, and the slope of the inclined surface is the same as the slope of the generatrix of the protective cap.

[0013] Furthermore, a plurality of balls are arranged on the inclined surface to convert the sliding friction between the expansion member and the protective cap into rolling friction.

[0014] Furthermore, a plurality of protrusions are provided on a side of the clip away from the protective cap to increase the contact area between the clip and the steel bar.

[0015] Furthermore, a ventilation hole is provided at one end of the protective cap away from the opening thereof.

[0016] Furthermore, a plurality of supporting members are arranged on the inner wall of the protective cap close to the ventilation hole, so that when the end of the steel bar is extended into the protective cap, a distance is left between the end of the steel bar and the ventilation hole.

[0017] The beneficial effects of the utility model are:

[0018] When the steel bar end protection tool of the utility model is in use, the expansion member is pushed to slide along the through groove in the direction away from the opening of the protective cap. Since the diameter of the open end of the protective cap gradually decreases toward the unopened end, the open end of the protective cap is pushed to open outward when the expansion member slides, so that the multiple clips are moved away from each other. At this time, the protective cap can be inserted into the steel bar end. After the insertion is completed, the expansion member is released, and the open end of the protective cap is deformed back to its original state, thereby driving the multiple clips to close together. Since the diameter of the hole formed by the multiple clips is smaller than the diameter of the steel bar, the multiple clips are surrounded and quickly clamped and fixed on the steel bar end under the force generated by the deformation of the protective cap back to its original state, thereby protecting the steel bar end and avoiding accidental bumps or scratches by the exposed end of the steel bar, thereby improving the safety of construction operations.

[0019] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and will be apparent to those skilled in the art based on the following examination and research, or can be taught from the practice of the present invention to some extent. The objectives and other advantages of the present invention can be achieved and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0028] In the above description of the utility model, it should be noted that the orientation or position relationship indicated by the terms "one side", "the other side", etc. is based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, and is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0029] In addition, the term "same" does not mean that the mechanisms must be absolutely identical, but slight differences are allowed. The term "vertical" simply means that the positional relationship between the mechanisms is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0030] See also Figures 1 to 4 The utility model provides a technical solution: a steel bar end protection tool, comprising a protective cap 1 made of elastic material, the protective cap 1 is in a cone-shaped structure as a whole, and the diameter of the opening end of the protective cap 1 is the largest;

[0031] The open end of the protective cap 1 is provided with a plurality of through slots 2 along its axial direction, and the through slots 2 radially penetrate the protective cap 1. The open end of the protective cap 1 is fixedly connected with a plurality of clips 3, and each of the clips 3 is located on the inner wall between two adjacent through slots 2;

[0032] The inner wall of the protective cap 1 is slidably connected with a propping member 4 for propping the clips 3 outward to open the open end of the protective cap 1. The plurality of clips 3 can be clamped and fixed on the end of the steel bar under the force generated by the deformation of the protective cap 1.

[0033] When the steel bar end protection tool of the utility model is in use, the expansion member 4 is pushed to slide along the through groove 2 in the direction away from the opening of the protective cap 1. Since the diameter of the open end of the protective cap 1 gradually decreases toward the unopened end, the expansion member 4 pushes the open end of the protective cap 1 to open outward when it slides, so that the multiple clips 3 are moved away from each other. At this time, the protective cap 1 can be inserted into the steel bar end. After the insertion is completed, the expansion member 4 is released, and the open end of the protective cap 1 is deformed back to its original state, thereby driving the multiple clips 3 to close together. Since the diameter of the hole formed by the multiple clips 3 is smaller than the diameter of the steel bar, the multiple clips 3 are quickly clamped and fixed on the steel bar end under the force generated by the deformation of the protective cap 1 back to its original state, thereby protecting the steel bar end and avoiding accidental bumps or scratches by the exposed end of the steel bar, thereby improving the safety of construction operations.

[0034] See also Figures 1 to 4 In this embodiment, the support member 4 is in a circular ring shape, and a plurality of paddle pieces 5 are arranged on the outer circumferential surface of the support member 4 . The free ends of the paddle pieces 5 extend outward through the through slot 2 .

[0035] In the present solution, since the free end of the toggle piece 5 passes through the through slot 2 and extends out of the protective cap 1, the toggle piece 5 can push the expansion piece 4 to slide outside the protective cap 1, and the expansion piece 4 is in a circular ring shape, so when the expansion piece 4 slides, it can squeeze the protective cap 1 outward and expand the plurality of clips 3 outward at the same time, which is conducive to quickly inserting the protective cap 1 onto the end of the steel bar.

[0036] See also Figure 1 and Figure 2 In this embodiment, the toggle piece 5 is T-shaped, and the toggle piece 5 includes a connecting portion 51 fixedly connected to the propping member 4, and a toggle portion 52 integrally formed with the connecting portion 51, the width of the toggle portion 52 is greater than the width of the connecting portion 51, and an avoidance distance is left between the toggle portion 52 and the outer wall of the protective cap 1.

[0037] In the present solution, the toggle piece 5 is designed to be T-shaped, which can increase the contact area between the toggle piece 5 and the user's finger, and an avoidance distance is left between the toggle portion 52 and the outer wall of the protective cap 1 to avoid the toggle portion 52 blocking and interfering with the open end of the protective cap 1 when it opens outward, thereby ensuring the opening degree of the hole formed by the multiple clips 3, so that the protective cap 1 can be smoothly inserted into the end of the steel bar.

[0038] See also Figure 3 and Figure 4 In this embodiment, an outer circumferential surface of the expansion member 4 is provided with an inclined surface 6 , and the slope of the inclined surface 6 is the same as the slope of the generatrix of the protective cap 1 .

[0039] In this solution, the inclined surface 6 can make the expansion member 4 and the protective cap 1 have surface contact. Compared with line contact, it is more conducive to the expansion member 4 to smoothly push the open end of the protective cap 1 to open outward when moving, and can reduce the pressure of the expansion member 4 on the protective cap 1 during the sliding process, thereby increasing the service life of the protective cap 1.

[0040] See also Figure 3 and Figure 4 In this embodiment, a plurality of balls 7 are arranged on the inclined surface 6 to convert the sliding friction between the opening member 4 and the protective cap 1 into rolling friction.

[0041] In this solution, by installing the ball 7 on the inclined surface 6, the sliding friction between the expansion member 4 and the protective cap 1 can be converted into rolling friction, which reduces the friction force and facilitates the smooth movement of the expansion member 4 to expand the opening end of the protective cap 1.

[0042] See also Figure 1In this embodiment, a plurality of protrusions 8 are provided on the side of the clip 3 away from the protective cap 1 to increase the contact area between the clip 3 and the steel bar.

[0043] In this solution, the contact area between the clip 3 and the steel bar can be increased by the protrusion 8, so that the protective cap 1 can be clamped outside the steel bar more stably, and the protrusion 8 can axially limit the protective cap 1 to avoid relative sliding between the protective cap 1 and the steel bar, thereby ensuring the stability of the installation of the protective cap 1.

[0044] See also Figure 2 and Figure 4 In this embodiment, a ventilation hole 9 is provided at one end of the protective cap 1 away from its opening; a plurality of support members 10 are provided on the inner wall of the protective cap 1 close to the ventilation hole 9, so that when the end of the steel bar is extended into the protective cap 1, a distance is left between the end of the steel bar and the ventilation hole 9.

[0045] In this solution, ventilation through the ventilation holes 9 can accelerate the dissipation of moisture in the protective cap 1 and reduce the accumulation of water in the protective cap 1, thereby avoiding rust on the ends of the steel bars. At the same time, the ends of the steel bars are supported by the support members 10 to avoid direct contact between the ends of the steel bars and the inner wall of the protective cap 1, thereby ensuring air circulation and avoiding rust.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
