Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an adjustable building construction safety door. Background Technology

[0002] Construction safety gates can prevent unauthorized personnel from entering the construction area, ensure the safety of construction workers, reduce the occurrence of accidents, and provide a certain degree of protection for construction projects.

[0003] A search revealed Chinese patent CN214576259U, which discloses a safety protection device for municipal construction, comprising a main body and a fixing device. A bracket is fitted onto and slidably connected to the main body. The fixing device is located on the surface of the main body and includes a limiting block fixedly connected to the surface of the main body. A fixing block is also fixedly connected to the surface of the main body, with the side of the fixing block furthest from the bracket slidably connected to the surface of the limiting block. This invention solves the problem that most current construction safety equipment uses a single insert rod to fix the safety door, which leads to the safety door easily shaking during use. This causes excessive friction and collision between the safety doors, accelerating wear and tear, shortening the equipment's lifespan, and hindering normal operation. The application of this device effectively avoids these problems and improves the stability of the equipment.

[0004] The safety protection device for municipal construction in the aforementioned patent has the following shortcomings: it cannot adjust the height of the main body of the protective door according to the needs of on-site construction. Different construction sites have different height requirements, and the fixed-height protective door cannot meet the needs of certain specific places. It has low flexibility and cannot adapt to different sites and building structures. Therefore, it is necessary to design an adjustable construction protective door to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable construction safety door.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable construction safety door includes two brackets. A first safety door is slidably connected to each bracket. Four first guide rods pass through each bracket, slidably connecting to the brackets. The four first guide rods at the same end are fixedly connected to the same first safety door. Each first safety door has a mounting groove, within which a second safety door is installed. A first fixing seat is fixedly connected to the bottom of each first safety door on its opposite side. A worm gear passes through the first fixing seat, and a worm wheel is fitted to the bottom of the worm gear. A first fixing shaft is fixedly connected to the two worm wheels on their adjacent sides. A connecting shaft is fixedly connected to the first fixing shaft on its side away from the worm wheel. The connecting shaft passes through the first safety door, and a first bevel gear is fixedly connected to one side of the connecting shaft. The first bevel gear meshes with a second bevel gear. The wheel has a second fixed shaft fixedly connected to the top of the second bevel gear, and an adjusting screw is fixedly connected to the top of the second fixed shaft. The adjusting screw is fitted with a screw nut, which is compatible with the adjusting screw. A second protective door is fixedly connected to the outer wall of the screw nut. Because a second protective door that can move up and down is adopted, the height of the second protective door can be adjusted according to the needs of the construction site, better adapting to various building structures. This effectively solves the problem in the background technology that the height of the protective door body cannot be adjusted according to the needs of on-site construction. Different construction sites have different height requirements, and a fixed-height protective door cannot meet the needs of certain specific places, has low flexibility, and cannot adapt to different sites and building structures. Thus, it achieves the technical effect of simple operation, easy adjustment of the height of the protective door, high flexibility, and the ability to adjust according to the height requirements of different construction sites.

[0008] Preferably, the first fixed bushing is provided with a first fixed sleeve, which is fixedly connected to the first protective door, and the second fixed bushing is provided with a second fixed sleeve, which is fixedly connected to the first protective door.

[0009] Preferably, two second guide rods are provided in the mounting groove, and the second guide rods are fixedly connected to the first protective door.

[0010] Preferably, the second guide rod passes through the second protective door, and the second protective door is slidably connected to the second guide rod.

[0011] Preferably, a rotating wheel is fixedly connected to one side of the worm gear.

[0012] Preferably, one of the first protective doors has a square groove, and a limiting plate is fixedly connected to one side of the other first protective door. The limiting plate is disposed in the square groove, and a slot is provided on the limiting plate. A pin is provided in the slot, and a sliding rod is fixedly connected to the top of the pin. A handle is fixedly connected to the top of the sliding rod.

[0013] Preferably, both the sliding rod and the pin are fitted with a second fixing seat, both the sliding rod and the pin are slidably connected to the second fixing seat, a spring is fitted on the sliding rod, and both second fixing seats are fixedly connected to the same first protective door.

[0014] The beneficial effects of this utility model are as follows:

[0015] Because of the adoption of a movable second protective door, the height of the second protective door can be adjusted according to the needs of the construction site, better adapting to various building structures. This effectively solves the problem mentioned in the background technology that the height of the protective door body cannot be adjusted according to the needs of on-site construction. Different construction sites have different height requirements, and fixed-height protective doors cannot meet the needs of certain specific locations, have low flexibility, and cannot adapt to different sites and building structures. Thus, it achieves the technical effect of simple operation, easy adjustment of the protective door height, high flexibility, and the ability to adjust according to the height requirements of different construction sites.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-8An adjustable construction safety door includes two brackets 1, each with a first safety door 2 slidably connected to it. Four first guide rods 3 pass through each bracket 1, slidably connecting to the brackets 1. The four first guide rods 3 at the same end are fixedly connected to the same first safety door 2. Each first safety door 2 has a mounting groove 4, within which a second safety door 5 is installed. A first fixing seat 6 is fixedly connected to the bottom of each first safety door 2 on its opposite side. A worm gear 7 passes through the first fixing seat 6, and a worm wheel 8 is fitted to the bottom of the worm gear 7. A first fixing shaft 9 is fixedly connected to the two worm wheels 8 on their adjacent sides. A connecting shaft 10 is fixedly connected to the first fixing shaft 9 on its side away from the worm wheel 8. The connecting shaft 10 passes through the first safety door 2, and a first bevel gear 11 is fixedly connected to one side of the connecting shaft 10, meshing with a second bevel gear 1. 2. A second fixed shaft 13 is fixedly connected to the top of the second bevel gear 12. An adjusting screw 14 is fixedly connected to the top of the second fixed shaft 13. A screw nut 15 is sleeved on the adjusting screw 14. The screw nut 15 is adapted to the adjusting screw 14. The outer wall of the screw nut 15 is fixedly connected to the second protective door 5. Because the technology of a second protective door that can be moved up and down is adopted, the height of the second protective door can be adjusted according to the needs of the construction site, better adapting to various building structures. This effectively solves the problem mentioned in the background technology that the height of the protective door body cannot be adjusted according to the needs of the construction site. Different construction sites have different height requirements. A fixed-height protective door cannot meet the needs of certain specific places, has low flexibility, and cannot adapt to different sites and building structures. Thus, it achieves the technical effect of simple operation, easy adjustment of the height of the protective door, high flexibility, and the ability to be adjusted according to the height requirements of different construction sites.

[0027] In this utility model, a first fixed shaft 9 is fitted with a first fixed sleeve 16, and the first fixed shaft 9 will rotate within the first fixed sleeve 16 to ensure the stability of the position of the first fixed shaft 9. The first fixed sleeve 16 is fixedly connected to the first protective door 2. A second fixed shaft 13 is fitted with a second fixed sleeve 17, and the second fixed shaft 13 will rotate within the second fixed sleeve 17 to ensure the stability of the position of the second fixed shaft 13. The second fixed sleeve 17 is fixedly connected to the first protective door 2.

[0028] In this utility model, two second guide rods 18 are provided in the mounting groove 4, and the second guide rods 18 are fixedly connected to the first protective door 2.

[0029] In this utility model, the second guide rod 18 passes through the second protective door 5, and the second protective door 5 is slidably connected to the second guide rod 18. When the second protective door 5 rises or falls, it will move along the second guide rod 18 to ensure the stability of the second protective door 5 when it moves.

[0030] In this utility model, a rotating wheel 19 is fixedly connected to one side of the worm gear 7.

[0031] In this utility model, one of the first protective doors 2 has a square groove 20, and the other first protective door 2 has a limiting plate 21 fixedly connected to one side. The limiting plate 21 is set in the square groove 20, and the limiting plate 21 has a slot 22. A pin 25 is set in the slot 22, and a sliding rod 24 is fixedly connected to the top of the pin 25. A handle 26 is fixedly connected to the top of the sliding rod 24.

[0032] In this utility model, both the sliding rod 24 and the pin 25 are fitted with a second fixing seat 23. The sliding rod 24 and the pin 25 are slidably connected to the second fixing seat 23. A spring 27 is fitted on the sliding rod 24. When the pin 25 rises, the sliding rod 24 also rises, and the sliding rod 24 will compress the spring 27 to make the spring 27 contract. When the pin 25 falls, the spring 27 extends, so that the pin 25 can be stably inserted into the slot 22, ensuring the stability of the position between the two first protective doors 2. Both second fixing seats 23 are fixedly connected to the same first protective door 2.

[0033] Working Principle: During use, the bracket 1 is installed and fixed by bolts passing through the holes at the bottom of the bracket 1. The two first protective doors 2 are moved to open and close the protective device. When closing the two first protective doors 2, the handle 26 is raised, causing the sliding rod 24 to rise. The rising sliding rod 24 compresses the spring 27, causing it to contract. The rising sliding rod 24 also causes the pin 25 to rise, moving it out of the slot 22. At this point, the limit is released, allowing the two first protective doors 2 to approach each other until they close. The movement of the first protective doors 2 causes the first guide rod 3 to move along the bracket 1, ensuring stability during the lateral movement of the first protective doors 2. When the two first protective doors 2 contact, the handle 26 is released, and the contracted spring 27 extends, allowing the pin 25 to descend and re-insert into the slot 22, thus limiting the position of the limit plate 21 and completing the closure for protection. Opening the protective device follows the same steps, moving the two first protective doors 2 away from each other. The height of the second protective door 5 can be adjusted to adapt to different sites and construction methods. During construction, the rotating wheel 19 rotates, which in turn drives the worm gear 7 to rotate. The worm gear 7 then drives the worm wheel 8 to rotate, which in turn drives the first fixed shaft 9 to rotate. The first fixed shaft 9 then drives the connecting shaft 10 to rotate, which in turn drives the first bevel gear 11 to rotate. The first bevel gear 11 then drives the second bevel gear 12 to rotate, which in turn drives the second fixed shaft 13 to rotate. The second fixed shaft 13 then drives the adjusting screw 14 to rotate, which in turn moves the screw nut 15. The height of the second protective door 5 is adjusted by moving the second protective door 5. The second protective door 5 will move along the second guide rod 18 to ensure the stability of the second protective door 5 during movement. When the first protective door 2 moves, it will drive the second guide rod 18 to move, and the second guide rod 18 will drive the second protective door 5 to move. Therefore, when adjusting the lateral position of the first protective door 2, the lateral position of the second protective door 5 can also be adjusted, controlling the closure between the two second protective doors 5. When it is necessary to lower the second protective door 5, the wheel 19 can be rotated in the opposite direction to lower the second protective door 5.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
