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. Example
[0020] like Figure 1-4As shown, a semi-automatic safety door locking system disclosed in this embodiment includes an operating platform door body 11 hinged on one side of a safety door frame 10, and an automatic locking mechanism is arranged on the other side of the operating platform door body 11, and the automatic locking mechanism includes a door lock pull ring 1, a connecting rod 2, a triangular baffle 3, a connecting rod shell 4, a triangular baffle slot 5, a fixing bolt 1 601, a fixing bolt 2 602, an outer baffle 7, an inner resistance plate 8 and a connecting piece 9, the door lock pull ring 1 is connected to one end of the connecting rod 2, and the connecting rod 2 is plugged into In the connecting rod shell 4, the lower end of the door lock pull ring 1 is connected to the connecting rod 2 in the natural state, and can be lifted upward when the door is opened. The connecting rod shell 4 is fixed to the other side of the operating platform door body 11, and the length of the connecting rod shell 4 is adjusted according to the height of the operating platform door body 11 and ensured to be consistent with the height of the operating platform door body 11. An active cavity 401 is provided inside the lower part of the connecting rod shell 4, and the bottom and side of the active cavity 401 are both open. The other end of the connecting rod 2 is connected to the connecting rod 2. The upper end of the connecting piece 9 is welded, and a triangular baffle plate retaining groove 5 is provided on the inner surface below the connecting rod housing 4, and the triangular baffle plate retaining groove 5 is communicated with the inside of the active cavity 401 through the side opening of the active cavity 401, and the lower end of the connecting piece 9 is hinged to the second corner 301 of the triangular baffle plate 3 through the second fixing bolt 602, and the right angle 302 of the triangular baffle plate 3 is hinged to the triangular baffle plate retaining groove 5 through the first fixing bolt 601, and the third corner 303 of the triangular baffle plate 3 is exposed from the bottom opening of the active cavity 401, in the safety An inner resistance plate 8 is provided on the inner side of the bottom of the door frame 10 for locking the operating platform door body 11 by abutting against the third corner 303 of the triangular baffle 3; an outer baffle 7 located on the outside of the safety door frame 10 is provided on the outside below the connecting rod housing 4, and the outer baffle 7 abuts against the outer side of the safety door frame 10 when closing the door. When the door lock pull ring 1 is pulled upward, the second corner 301 of the triangular baffle 3 is pulled upward, so that the third corner 303 of the triangular baffle 3 is lifted upward at the same time to separate from the inner resistance plate 8, thereby opening the door.
[0021] In this structure, the connecting rod 2 and the triangular baffle 3 are formed into a movable whole through the connecting piece 9 and the fixing bolt 1 601. There is a distance between the connecting rod 2 and the triangular baffle 3 for the triangular baffle 3 to move upward, ensuring that it can move upward. The other end: the fixing bolt 2 602, the triangular baffle positioning groove 5 and the triangular baffle 3 are connected to form a hinged whole, so that the other side of the triangular baffle 3 can move upward with the hinge as the center of the circle. At the same time, the interior of the connecting rod shell 4 is hollow to prevent the triangular baffle 3 from colliding with the connecting rod shell 4 upward, so that the upward height cannot reach the height of crossing the internal resistance plate 8. The triangular baffle 3 is cut at an acute angle parallel to the right angle to form a notch 304, which increases the thickness of the obstruction and the internal resistance plate. At the same time, the oblique edge of the triangular baffle 3 is easier to slide over the internal resistance plate 8. The internal resistance plate 8 at the bottom prevents the safety door from opening automatically in the closed state by blocking the triangular baffle 3.
[0022] Preferably, a notch 304 is provided at the bottom of the third corner 303 of the triangular baffle 3, which not only increases the thickness in contact with the inner baffle 8 and improves the stability of the door lock, but also makes it easier to pass through the inner baffle and open the safety door when the pull ring is lifted upward when the door is opened; at the same time, the oblique edge of the triangular baffle 3 is easier to slide over the inner baffle when the door is closed.
[0023] Preferably, the connecting rod 2 is made of a 2 mm thick steel plate and is formed into two small rectangular strips, and the two small rectangular strips are parallel and spaced apart.
[0024] Preferably, the opening size of the side of the movable cavity 401 needs to ensure that there is a movable gap between the triangular baffle 3 and the upper edge of the opening of the side of the movable cavity 401 when the door is closed, and ensure that the triangular baffle 3 has an upward movable angle when the door is opened.
[0025] Preferably, the triangular baffle 3 is made of a 12 mm thick steel plate.
[0026] Preferably, the triangular baffle plate retaining groove 5 is formed by a 6 mm thick U-shaped retaining groove, and both ends of the triangular baffle plate retaining groove 5 are welded to the connecting rod housing 4 .
[0027] Preferably, the outer baffle plate 7 is made of 6 mm thick steel plate into a rectangular steel strip with a width of 40 mm and a length of 150 mm, and the upper end of the outer baffle plate 7 is welded to the lower end of the connecting rod outer shell 4, and the lower end of the outer baffle plate 7 and the bottom of the safety door frame 10 block each other to prevent the safety door from moving too far inward. At the same time, its length needs to extend to the bottom of the safety door frame 10 to prevent the safety door from moving inward.
[0028] Preferably, the inner resistance plate 8 is made of a steel plate with a thickness of 15 mm and a length of 50 mm. If the left and right doors are used to open the door, the length of the inner resistance plate 8 is increased to 100 mm, and the lower end of the triangular baffle plate 3 blocks the inner resistance plate 8 to ensure that the door is closed firmly and achieve an automatic fixing effect. Moreover, the triangular baffle plate 3, the outer baffle plate 7, and the inner resistance plate 8 restrain each other. When the worker closes the door, the bevel of the triangular baffle plate 3 slides over the inner resistance plate 8. At the same time, the outer baffle plate 7 prevents the safety door from being too inward, and the inner resistance plate 8 prevents the safety door from being opened again, thereby achieving a semi-automatic door closing effect, reducing safety hazards, and ensuring safe construction on site.
[0029] Preferably, the connecting rod housing 4 is a square tube with a thickness of 6 mm and a width of 50 mm, and the length of the connecting rod housing 4 is the same as that of the internal connecting rod 2 .
[0030] As a preferred embodiment, the door lock pull ring 1 is made of round steel to form a ring structure with an outer diameter of 12 mm. This structure mainly adopts the lower triangular baffle plate 3, the inner resistance plate 8, and the outer baffle plate 7 as the core to form the lock door fixation. The upper end lock door pull ring 1 pulls the triangular baffle plate 3 up and down through the connecting rod 2 to open the door. The door is closed gently through the three core devices at the lower end to achieve automatic locking. Through the overall construction method, various platform items are prevented from falling off, ensuring the safety of workers during construction. Among them, the connecting rod shell 4 in this structure plays a role in protecting the internal connecting rod 2. At the same time, the outer baffle plate 7 is connected to the lower end of the connecting rod shell 4. The outer baffle plate 7 collides with the bottom of the lower end of the safety door frame 10 to prevent The closing of the safety door causes the inward angle to be too large. The lock door pull ring 1 is located at the upper end of the connecting rod housing 4 and is connected to the internal connecting rod 2. When the lock door pull ring 1 naturally droops and connects to the upper end of the connecting rod housing 4, the lower triangular baffle 3 is horizontal. When closing the door, gently push the safety door, and the lower triangular baffle 3 bevels and connects to the inner resistance plate 8. Under the action of normal force, it slides through the inner resistance plate 8 through the bevel angle. At this time, the outer baffle 7 is connected to the lower end to prevent it from opening in the inward direction, and the inner resistance plate 8 prevents it from opening in the outward direction. The whole interacts with each other to achieve the safety lock door. The lock door pull ring 1 is pulled upward, and the lower triangular baffle 3 transmits the connecting rod 2 through the connecting piece 9. The fixing bolt 2 602 at the triangular baffle card slot 5 is the fixed point circle center. The fixing bolt 1 601 at the end of the connecting piece 9 moves upward with the center of the circle, so that the triangular baffle passes through the inner resistance plate to achieve the effect of opening the door. The worker opens the door by pulling the lock door pull ring 1 upward, and gently pushes through the lower joint to achieve the effect of automatic locking when closing the door. The connecting rod 2 and the connecting rod housing 4 can be changed at any time according to the size of the equipment used, so as to improve the locking device of the safety door of the material platform, gas cylinder warehouse, etc., to prevent the loose parts from falling off during high-altitude stacking and hoisting, and at the same time improve the phenomenon that the operating platform door is opened or not closed at will, so as to ensure the safety of workers in on-site construction. Therefore, this structure greatly improves the safety of on-site steel structure construction. After using this invention, the safety doors of the on-site material platform, operating platform, etc. are normally closed, avoiding workers from using temporary fixing methods and improving the phenomenon that the safety doors are open at high altitude. Workers save the time of temporarily fixing and locking the door each time, which improves work efficiency. At the same time, it prevents the falling of items caused by workers missing the locking door on the high-altitude material platform, reduces the safety hazards of workers in the operating platform at the safety door, and provides a strong guarantee for on-site construction safety and worker safety. Moreover, this device can adjust the size according to the size and weight of the on-site equipment, so that this method can be used on a variety of platforms.
