Detailed Description

Further description is provided below in connection with the accompanying drawings.

The prior construction safety guard rail generally comprises a left supporting leg 1, a right supporting leg 1 and a scissor frame 2 arranged between the two root supporting legs 1, and the construction safety guard rail has an unfolding state and a folding state through deformation of the scissor frame 2. On the one hand, the construction safety guard rail can be made to have different lengths, and on the other hand, when not in use, the scissors fork 2 can be completely folded, so that the size is reduced, and the construction safety guard rail is convenient to place and transport.

Referring to fig. 1, 2 and 4, a construction safety guard rail has an unfolded state and a folded state, and when in the folded state, the construction safety guard rail also has a foldable state. It comprises the following steps: two supporting legs 1, two groups of scissors frames 2 and a plurality of third adapter blocks 5.

Referring to fig. 1, two legs 1 have the same structure, and one of them is taken as an example, and includes an upper connecting bar 1-1, a first adapter block 1-2, a lower connecting bar 1-3, and a base 1-4. The lower end of the upper connecting bar 1-1 is hinged to the upper position of the first adapter block 1-2 and marks the hinged position as a first upper hinged position. The upper ends of the lower connecting strips 1-3 are hinged to the lower positions of the first adapter blocks 1-2, and the hinged positions are marked as first lower hinged positions. The base 1-4 is connected to the lower end of the lower connecting strip 1-3, namely the base 1-4 has the following effects: the contact area between the construction safety guard rail and the ground is increased, and the placement stability of the construction safety guard rail is improved; the specific connection manner between the base 1-4 and the lower connecting strip 1-3 is not limited as long as the effect can be achieved, for example, the base and the lower connecting strip can be directly welded and fixed, and can also be connected through bolts.

Referring to fig. 1, the two sets of scissors frames 2 are also identical in structure and are respectively arranged between the two upper connecting strips 1-1 and between the two lower connecting strips 1-3. The left side and the right side of each group of scissor frames 2 are all hinged ends, and are all hinged with second adapter blocks 3-1. The second transfer blocks 3-1 on the left and right sides form two groups of connection groups 3 from top to bottom, namely, two upper second transfer blocks 3-1 are one group of connection groups 3, and two lower second transfer blocks 3-1 are the other group of connection groups 3. One group of connecting groups 3 are respectively and fixedly connected with the two upper connecting strips 1-1/lower connecting strips 1-3, and the other group of connecting groups 3 are respectively and slidably connected with the two upper connecting strips 1-1/lower connecting strips 1-3 so that the two groups of scissor frames 2 can be folded and unfolded.

Referring to fig. 1 and 3, a plurality of hinge ends of the two sets of scissor frames 2 close to each other are hinged with a fourth hinge block 4, and two fourth hinge blocks 4 aligned up and down of the two sets of scissor frames 2 are hinged with the same third hinge block 5 in sequence. Specifically, all lower hinge ends of the upper scissor frame 2 are hinged with fourth hinge blocks 4, and the fourth hinge blocks 4 are sequentially hinged at positions on the upper side of a plurality of third hinge blocks 5, and the hinge positions are marked as second upper hinge positions; all upper hinge ends of the lower scissor frame 2 are also hinged with fourth hinge blocks 4, and the fourth hinge blocks 4 are hinged with a plurality of third hinge blocks 5 in sequence at the lower position, and the hinge positions are marked as second lower hinge positions. Therefore, the two supporting legs 1 can be far away from/close to each other like the existing construction safety guard rail, the scissor frame 2 is driven to be unfolded/folded, namely, the scissor frame has an unfolding state and a folding state, and in addition, the following steps can be found: the third transfer block 5 correspondingly moves up and down during the expanding/collapsing process of the scissors frame 2.

Referring to fig. 1, the width of the third adapter blocks 5 is set, and when the third adapter blocks 5 are propped against each other, the above-mentioned folded state corresponds. In addition, when the construction safety protective fence is in a folded state, the second upper hinge position and the second lower hinge position are respectively overlapped with the first upper hinge position and the first lower hinge position. That is, the upper scissors frame 2 and the two upper connecting bars 1-1 can rotate together relative to the first and third transfer blocks 1-2 and 5, and the lower scissors frame 2 and the two lower connecting bars 1-3 can also rotate together relative to the first and third transfer blocks 1-2 and 5, corresponding to the foldable state.

When the construction safety protective guard is used, the fork frame 2 is unfolded, and the third switching block 5 moves up and down, so that the second upper hinge position and the second lower hinge position are staggered with the first upper hinge position and the first lower hinge position respectively, and the folding of the construction safety protective guard is limited.

When the construction safety guard rail is not used, the two supporting legs 1 are firstly made to be close to each other to achieve the furled state, the upper side scissor frame 2 and the two upper connecting strips 1-1 are rotated by 90 degrees together, the lower side scissor frame 2 and the two lower connecting strips 1-3 are also rotated by 90 degrees together, folding is completed, and the size is further reduced.

Referring to fig. 1, in one embodiment, the device further includes two first bolts 6 (for convenience in illustration, threads are not shown in the bolt and the threaded hole), the two first adapter blocks 1-2 are provided with threaded through holes matching the first bolts 6, and the outer side surfaces of the two third adapter blocks 5 at the outermost side are provided with first threaded holes matching the first bolts 6. Therefore, after the construction safety guard rail reaches the folded state, the first adapter blocks 1-2 and the third adapter blocks 5 on the same side can be connected through the two first bolts 6, so that the construction safety guard rail can be stably kept in the folded state, and subsequent folding is facilitated.

Referring to fig. 4, in one embodiment, the length of the upper connecting bar 1-1 is preferably equal to the length of the lower connecting bar 1-3. Thus, after folding, the upper connecting strip 1-1 and the lower connecting strip 1-3 can be overlapped. In connection with this, it is preferable that the two sets of connection sets 3 are arranged as follows: the upper connecting group 3 is fixedly connected with the two upper connecting strips 1-1 respectively, and the lower connecting group 3 is slidably connected with the two lower connecting strips 1-3 respectively. Therefore, when the construction safety guard rail is unfolded, the lower connecting group 3 and the third switching block 5 can move upwards, and the two groups of scissor frames 2 are positioned at upper positions after being unfolded, so that the point that the length of the upper connecting strip 1-1 is equal to the length of the lower connecting strip 1-3 can be matched more conveniently.

Referring to fig. 5, in one embodiment, further, the bases 1-4 are configured to: also comprises two second bolts 7; the bottom surface of the base 1-4 is provided with a groove 1-41, the groove 1-41 is provided with a waist-shaped through groove 1-42 communicated with the top surface of the base 1-4, and the top surface of the base 1-4 is fixedly provided with a clamping column 1-43; the bottom surface of the lower connecting strip 1-3 is provided with a second threaded hole matched with a second bolt 7; the first front side surface/first rear side surface of the upper connecting strip 1-1 (according to the specific position of the clamping column 1-43 on the top surface of the base 1-4) is provided with a clamping groove 1-11 matched with the clamping column 1-43; two second bolts 7 respectively penetrate through the kidney-shaped through grooves 1-42 and are connected with the corresponding lower connecting strips 1-3 in a threaded mode. The second bolt 7 is screwed down, the base 1-4 and the corresponding lower connecting strip 1-3 can be fixed, the second bolt 7 is unscrewed, and the base 1-4 and the corresponding lower connecting strip 1-3 can relatively rotate and relatively move. When the construction safety guard rail is folded, the clamping columns 1-43 can be matched with the clamping grooves 1-11 on the same side. Referring to fig. 4, before folding, the second bolt 7 is loosened, and the base 1-4 is rotated, so that the clamping column 1-43 does not influence the rotation of the upper connecting strip 1-1; referring to fig. 6, after the folding is completed, the base 1-4 is moved to keep the clamping column 1-43 away from the lower connecting strip 1-3, and then the base 1-4 is rotated to make the clamping column 1-43 to the outer side of the clamping groove 1-11 and align with the clamping groove 1-11; referring to fig. 7, finally, the base 1-4 is moved to make the clamping posts 1-43 fit the clamping grooves 1-11, and the second bolt 7 is screwed. Thus, the construction safety guard rail is stably kept to be folded by the second bolts 7 in cooperation with the bases 1 to 4.

Referring to fig. 5 and 7, in conjunction with the above arrangement of the base 1-4, when the clip 1-43 is matched with the clip groove 1-11, the second front side, the second rear side and the second outer side of the base 1-4 do not exceed the front edge 8, the rear edge 9 and the outer edge 10 of the upper connecting strip 1-1 and the lower connecting folded forming area, respectively, in the bottom view direction. Thus, the folded construction safety guard rail is integrally cuboid and is convenient to stack.
