Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a safety rope hook that is easy to open and close. Background Technology

[0002] Safety rope hooks are accessories that connect safety ropes to scaffolding. They are often used in construction projects to effectively improve the safety of construction workers. Although the safety rope hooks currently in use can meet normal usage requirements, they still have defects in actual use.

[0003] However, the safety rope hook is opened by pressing inwards, which can be easily opened even with little external force. This can easily cause safety hazards due to accidental contact. At the same time, the inner wall of the hook slides directly on the scaffold crossbar, which can easily cause wear and tear on the hook and affect its service life. Utility Model Content

Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1:

[0028] Reference Figures 1-5This is the first embodiment of the present invention, which provides a safety rope hook that is easy to open and close. It includes a hook body 100, a locking mechanism 200 mounted on the hook body 100, and a moving mechanism 300 mounted on the bottom of the hook body 100. The moving mechanism 300 includes a groove 301, which is a rectangular groove located at the center of the bottom of the hook body 100, but does not penetrate through the bottom of the hook body 100. Two fixing rods 302 are fixedly installed within the groove 301 and welded to both sides of the groove 301. Both ends of the fixing rods 302 penetrate through the hook body 100. The hook body 100 is fixedly welded inside the hook body 100 to ensure the contact area between the hook body 100 and the fixing rod 302, preventing both from breaking under stress. A rotating column 303 is rotatably installed on the outside of the fixing rod 302. The rotating column 303 has a through hole in the center. The rotating column 303 is sleeved on the fixing rod 302 to ensure that the rotating column 303 rotates stably on the fixing rod 302. The lower end of the rotating column 303 extends into the groove 301. The lower end of the rotating column 303 is embedded in the groove 301. Through the moving mechanism 300, the hook body 100 can be easily moved short distances on the scaffolding, avoiding hard damage to the hook body 100 and extending its service life.

[0029] The hook body 100 includes a hanging hole 101, which is a circular hole used to fix a safety rope. The hanging hole 101 is opened on the inner wall of the top of the hook body 100. The rotating column 303 is in the shape of a cylindrical block. The upper end of the rotating column 303 extends out of the groove 301. The rotating column 303 directly contacts the scaffolding to ensure that the hook body 100 will not be worn when it moves on the scaffolding, thus extending the service life of the hook body 100. There are two rotating columns 303, and two corresponding fixing rods 302 are also provided. The rotating column 303 rotates on the scaffolding instead of moving the hook body 100.

[0030] Example 2:

[0031] Reference Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, a spring 202 is fixedly installed on the inner wall of the bottom of the through groove 201. The spring 202 is a compression spring and is fixedly welded to the bottom groove of the through groove 201. A sliding block 203 is fixedly installed on the other end of the spring 202. The sliding block 203 is made of cast iron and is fixedly welded to the other end of the spring 202. At the same time, the weld is protected against rust.

[0033] Specifically, the sliding block 203 is a rectangular block with a smooth outer wall. The outer side of the sliding block 203 slides on the inner wall of the through groove 201. The sliding block 203 is confined within the through groove 201 and can slide up and down within the through groove 201.

[0034] Specifically, a push handle 205 is fixedly installed on the other side of the sliding block 203. The push handle 205 is in the shape of a cylindrical bar, made of cast iron, and is fixedly welded to the sliding block 203 to ensure that the two move synchronously. At the same time, the outer edge of the push handle 205 is covered with rubber to increase the comfort of the operator.

[0035] Example 3:

[0036] Reference Figures 1-4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0037] Specifically, a fixing bite tooth 102 is fixedly installed on the upper left side of the hook body 100. The hook body 100 and the fixing bite tooth 102 are made of high-strength steel and are cast in one piece to ensure their integrity.

[0038] Specifically, a movable engagement tooth 204 is fixedly installed on one side of the sliding block 203. The movable engagement tooth 204 is made of high-strength steel and is fixedly welded to the sliding block 203. The side of the movable engagement tooth 204 away from the sliding block 203 is in contact with the fixed engagement tooth 102. The movable engagement tooth 204 and the fixed engagement tooth 102 form a closed space. The movable engagement tooth 204 away from the fixed engagement tooth 102 opens the hook body 100.

[0039] In use, the safety rope is attached to the hook body 100 through the hook hole 101. Pushing the push handle 205 causes the sliding block 203 on the push handle 205 to slide along the inner wall of the through groove 201, compressing the spring 202. This causes the moving engagement tooth 204 to move away from the fixed engagement tooth 102, opening the hook body 100. The hook body 100 is then placed on the steel pipe of the scaffold. Releasing the push handle 205 resets the spring 202, causing the sliding block 203 to slide along the inner wall of the through groove 201. The sliding block 203 then moves the moving engagement tooth 204 until the moving engagement tooth 204 moves further away from the fixed engagement tooth 102. 4. When the fixed engagement tooth 102 is in contact, the movable engagement tooth 204 will not move without pushing the push handle 205, and the hook body 100 cannot be opened. When the steel pipe contacts the movable engagement tooth 204, it will only press the movable engagement tooth 204 and the fixed engagement tooth 102 tighter and tighter, preventing the hook body 100 from disengaging. When the hook body 100 is tightened, the rotating column 303 contacts the steel pipe, moves the hook body 100, and the rotating column 303 rotates on the fixed rod 302 and on the steel pipe, preventing the hook body 100 from contacting the steel pipe and protecting the hook body 100.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
