Description

Technical Field

[0001] The utility model relates to the technical field of building construction safety auxiliary equipment, in particular to a safety bracket for building construction. Background Art

[0002] Construction safety is a safety issue encountered in engineering construction across various industries, encompassing all safety issues encountered during construction operations. my country has always prioritized production safety and has enacted relevant laws and regulations, setting clear requirements for personnel and organizations involved in the construction industry. However, safety supports play a crucial role in building construction, improving efficiency, ensuring safety, and protecting the surrounding environment, providing crucial support for building construction and maintenance.

[0003] Among them, publication number CN214740490U discloses a safety bracket for construction, which secures the lower part of the guardrail by installing a base and a support rod, and secures the upper part of the guardrail by rotating a toggle block in a limiting mechanism and engaging the toggle block with the guardrail, thereby achieving the purpose of convenient installation and removal of the safety bracket. However, this document still has problems in actual use. Although the toggle block in the limiting mechanism secures the upper part of the guardrail by rotating a toggle block and engaging the guardrail, which allows the safety bracket to be installed and removed, it is not convenient to splice the brackets together, which can easily lead to the destruction of the protection range. Therefore, there is an urgent need for a safety bracket for construction that is easy to assemble and disassemble and has a large protection range. Utility Model Content

[0004] The content of this utility model is used to briefly introduce the concepts that will be described in detail in the detailed description section below. The content of this utility model is not intended to identify the key features or essential features of the technical solution for which protection is sought, nor is it intended to limit the scope of the technical solution for which protection is sought.

[0005] In response to the problems and shortcomings of the existing technology, the present invention aims to provide a safety support for construction, which can connect the protective support to the support column through a splicing mechanism, and is provided with multiple rollers and rollers on the inner frame of the protective support. In addition, the inner frame of the protective support is connected with a vertical buffer mechanism and a horizontal buffer mechanism, thereby effectively improving the neatness and integrity of the construction safety support and effectively reducing damage to the protective support caused by impact forces. It is used to solve the technical problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: it includes a protective bracket, multiple roller shafts are connected between the upper and lower ends of the inner frame of the protective bracket, and multiple roller wheels are sleeved on the outside of the roller shafts, both sides of the protective bracket are connected to the support column through a splicing mechanism, and at least two sides of the support column are provided with openings to clamp the protective bracket; the splicing mechanism includes a fixed cylinder connected to the outside of the support column, a connecting rod is connected to the inside of the fixed cylinder, the other end of the connecting rod is connected to the pin, the other end of the pin passes through the support column and the protective bracket, a first spring is sleeved on the outside of the connecting rod, one end of the first spring is connected to the inside of the fixed cylinder, and the other end is fitly connected to the pin.

[0007] Preferably, support blocks are connected to both the upper and lower ends of the inner frame of the protective bracket, and the support blocks at both ends are connected by guide rods. The support blocks are connected to the upper and lower ends of the inner frame of the protective bracket, specifically to the left and right sides of the inner frame near the roller axis. Connecting the two support blocks via guide rods can improve the stability of the protective bracket.

[0008] Preferably, a vertical buffer mechanism is provided on the outer side of the guide rod. The vertical buffer mechanism includes a sliding sleeve that is slidably connected to the upper and lower ends of the outer side of the guide rod. The two sliding sleeves are connected by a second spring. The outer side of the sliding sleeve is rotatably connected to the rotating rod via an adapter, and the other end of the transmission rod is rotatably connected to the inner side of the curved plate via the adapter. During use, the two sliding sleeves slide up and down along the outer side of the guide rod. In combination with the second spring, the curved plate can be extended in a normal state, thereby providing vertical buffer protection for the protective bracket.

[0009] Preferably, a transverse buffer mechanism is provided between the support block and the curved plate. The transverse buffer mechanism comprises a cylinder connected to the inner side of the curved plate, the other end of the cylinder extending into a sleeve for connection, the sleeve being connected to the support block, and a third spring connected to the interior of the sleeve, which abuts against the cylinder. The sleeves are connected to the sides of the upper and lower support blocks, respectively, while the cylinder connected to the inner side of the curved plate extends into the sleeve for connection. Combined with the third spring, this can further mitigate damage to the safety protection bracket caused by impact forces and limit the position of the curved plate.

[0010] Preferably, damping particles are connected to the interior of the sleeve and are interlaced with the cylinder. The primary function of the damping particles is to induce inelastic collisions and friction between particles and between particles and the inner wall of the cavity, thereby generating a damping effect and achieving good shock absorption. The damping particles are interlaced with the cylinder, and when the protective bracket is impacted, the third spring is compressed, thereby partially reducing the impact force. As the impact force weakens, the third spring recovers its elasticity, causing the cylinder to reset. After the cylinder resets, it contacts the damping particles, absorbing the rebound force, thereby providing a buffering effect.

[0011] Preferably, the end of the connecting rod away from the latch passes through the fixed tube and is fixedly connected to a handle. The end of the connecting rod away from the latch passes through the fixed tube and is fixedly connected to the handle, with the end of the handle abutting against the end of the fixed tube. By pulling the handle outward and simultaneously rotating it, the latch is quickly removed from the protective bracket, allowing for rapid separation of the protective bracket from the support column, thereby improving the efficiency of assembly and disassembly of the present invention.

[0012] Preferably, grooves are formed inwardly on the edges of both sides of the protective bracket, which engage with protrusions extending inwardly from the side openings of the support column. The engagement of the grooves provided on both sides of the protective bracket with the protrusions extending inwardly from the side openings of the support column can help fix the position of the protective bracket when it is installed on the support column, and the splicing mechanism can then be used to firmly connect the two, further improving the installation efficiency of the protective bracket.

[0013] Preferably, the number of the rollers is five, and the number of the roller shafts is four.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This utility model features a simple structure and easy assembly, significantly improving the efficiency of safety bracket assembly and disassembly during construction. A splicing mechanism allows individual safety brackets to be quickly spliced ​​together to form a safety guardrail, thereby improving the safety guardrail's neatness and integrity. The coordination between the roller shaft and the roller wheel transfers most of the impact force, thereby improving the stability of the safety guardrail. A latch locks the safety guardrail in place, allowing it to be quickly inserted into the support column to complete the installation of the safety guardrail. Vertical and lateral buffering mechanisms are also provided to mitigate impacts from external objects, thereby increasing the safety guardrail's service life. When an external impact force strikes the curved plate, the third spring is compressed to partially offset the impact force. The third spring then resets the cylinder, where the contact damping particles absorb the rebound force, thereby providing a buffering effect. The curved plate then drives the two sliding sleeves to simultaneously compress the second spring, further buffering the impact force absorbed by the compressed second spring, effectively mitigating damage to the safety guardrail.

On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0026] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. Example

[0027] This embodiment provides a safety bracket for construction, such as Figure 1-8 The protective bracket 1 comprises a plurality of rollers 2 connected between the upper and lower ends of the inner frame of the protective bracket 1. Multiple rollers 3 are sleeved around the outer edges of the rollers 2. The two sides of the protective bracket 1 are connected to support columns 4 via splicing mechanisms 5. Multiple rollers 2 are fixedly connected between the upper and lower ends of the inner frame of the protective bracket 1. In this embodiment, there are four rollers 2, evenly distributed throughout the inner frame of the protective bracket 1. Multiple rollers 3 are rotatably sleeved around the outer edges of the rollers 2. In this embodiment, there are five rollers 3, also evenly distributed around the outer edges of the rollers 2. The interaction between the rollers 2 and 3 deflects a significant portion of the impact force, thereby enhancing the stability of the protective bracket 1. Furthermore, grooves are formed on both sides of the protective bracket 1, which engage with protrusions extending inward from the side openings of the support columns 4. This helps secure the protective bracket 1 during installation, further improving installation efficiency. In particular, openings are provided on both sides of the support column 4 to facilitate connecting multiple protection brackets 1 to form a safety guardrail.

[0028] This embodiment further includes support blocks 6 connected to both the upper and lower ends of the inner frame of the protective bracket 1, and the support blocks 6 at the upper and lower ends are connected by guide rods 7. The support blocks 6 are specifically located on the left and right sides of the inner frame of the protective bracket near the roller axis, and the upper and lower support blocks 6 are connected by the guide rods, which can improve the stability of the protective bracket 1 during use.

[0029] This embodiment also includes a splicing mechanism 5. Specifically, the splicing mechanism 5 includes a fixed tube 504, which is fixedly connected to the outer side of the upper end of the support column 4. The inner bottom of the fixed tube 504 is connected to a connecting rod 503, and the outer side of the connecting rod 503 is sleeved with a first spring 502. One end of the first spring 502 is fixedly connected to the inner bottom of the fixed tube 504, and the other end of the first spring 502 is in affixed connection with the latch 501. The end of the latch 501 closest to the first spring 502 is fixedly connected to the connecting rod 503, and the end of the latch 501 away from the first spring 502 passes through the support column 4 and is connected to the protective bracket 1. The provision of the first spring 502 ensures that the latch 501 is always connected to the protective bracket 1 in the absence of external forces. The end of the connecting rod 503 away from the latch 501 passes through the fixed tube 504 and is fixedly connected to a handle 505, so that the end of the handle 505 is in affixed connection with the end of the fixed tube 504. By pulling the handle 505 outward and rotating it at the same time, the latch 501 can be taken out of the protective bracket 1 and its position can be fixed, so that the protective bracket 1 can be quickly taken out of the support column 4.

[0030] This embodiment also includes a vertical buffer mechanism 8 and a horizontal buffer mechanism 9. Specifically, the vertical buffer mechanism 8 includes a sliding sleeve 802. A second spring 803 is sleeved at the center position of the outer side of the guide rod 7, and the upper and lower ends of the second spring 803 are fixedly sleeved with the sliding sleeve 802, and the upper and lower sliding sleeves 802 are internally connected by sliding along the outer side of the guide rod 7. By providing the second spring 803, the arc plate 801 can be in an expanded state under normal conditions to protect the protective bracket 1. Adapters are symmetrically provided on the left and right sides of the sliding sleeve 802 and are rotatably connected to the connecting rod 804, and then the end of the rotating rod 804 away from the sliding sleeve 802 is rotatably connected to the inner side of the arc plate 801 through the adapter. Among them, the arc plate 801 is set as an arc structure, and the arc plate 801 is placed on both sides of the support block 6 and the guide rod 7, which also protects both.

[0031] The transverse buffer mechanism 9 includes a cylinder 901 connected to the curved plate 801. The upper and lower ends of the inner side of the curved plate 801 are fixedly connected to the cylinder 901. By setting the cylinder 901, the position of the curved plate 801 can be limited. The outer side of the cylinder 901 is provided with a sleeve 902, that is, one end of the cylinder 901 extends into the interior of the sleeve 902 and is connected, and the sleeve 902 is fixedly connected to the support block 6. The inner bottom of the sleeve 902 is fixedly connected to a third spring 903, and the other end of the third spring 903 is fitted and connected to the cylinder 901. The other side of the sleeve 902 is fixedly connected to damping particles 904, and the damping particles 904 are interlaced with the cylinder 901. When in use, the third spring 903 is compressed to consume a portion of the impact force. After that, the third spring 903 resets the cylinder 901. The cylinder 901 resets and contacts the damping particles 904 to absorb the rebound force, thereby providing further buffering protection.

[0032] The use method of this utility model:

[0033] Before using the safety bracket for construction of this utility model, it is necessary to check the overall condition of the device to ensure that it can work normally. Figures 1 to 8 As shown, the protective bracket 1 is clamped in the designated position of the support column 4, and the splicing mechanism 5 is used to connect and fix them, so that multiple protective brackets 1 are assembled into a safety guardrail in sequence. During use, when the protective bracket 1 is hit by an external object, the cooperation between the roller shaft 2 and the roller wheel 3 can transfer most of the impact force, thereby improving the stability of the protective bracket 1. Then, when the external impact force hits the curved plate 801, the third spring 903 is compressed to reduce a part of the impact force, and then the third spring 903 resets the cylinder 901. The cylinder 901 resets and contacts the damping particles 904 to absorb the rebound force, thereby playing a buffering role. Then the curved plate 801 drives the two sliding sleeves 802 to squeeze the second spring 803 at the same time, and the second spring 803 is compressed to absorb a part of the impact force, thereby further buffering, which can effectively slow down the damage of the impact force to the protective bracket 1. Secondly, when the protective bracket 1 needs to be removed, just hold the handle 505 and pull it outward, and at the same time rotate the handle 505 to separate the end of the handle 505 from the end of the fixing tube 504. The pin 501 can be removed from the protective bracket 1 and its position can always be ensured to be fixed. The protective bracket 1 can then be removed from the support column 4 to complete the disassembly of the protective bracket 1.
