[0008] Preferably, the protection device further includes an auxiliary pressing mechanism. The auxiliary pressing mechanism includes a vertical pressing rod, a first connecting rod, a second connecting rod, an auxiliary pressing block, and a second pressing mechanism. A vertical sleeve is vertically and fixedly arranged in the middle of the main support pipe. The vertical pressing rod is sleeved in the vertical sleeve and can move up and down freely relative to the vertical sleeve. A vertical support ear is fixedly arranged at the lower parts of the left end and the right end of the main support pipe. The vertical support ear is hinged to one end of the corresponding first connecting rod.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following will combine specific embodiments and the attached Figures 1-4 , and clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some preferred embodiments of the present invention, rather than all embodiments. Those skilled in the art can make similar deformations without violating the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.
[0020] The present invention provides a detachable edge and opening protection device (as Figure 1 shown), including a main support pipe 1 and a telescopic sleeve rod 2. A telescopic sleeve rod 2 is sleeved at both the left and right ends of the main support pipe 1. The main support pipe 1 and the telescopic sleeve rod 2 can both be processed from steel pipes. The telescopic sleeve rod 2 can slide freely left and right relative to the main support pipe 1. By using the telescopic adjustment ability of the telescopic sleeve rod 2 in the main support pipe 1, the support span of the transverse support rod composed of the main support pipe 1 and the telescopic sleeve 2 can be adjusted, and then it is convenient to install the present invention on the edge and opening with different transverse spans, improving the flexible applicability of the present invention. At the outer end of the telescopic sleeve rod 2, an L-shaped clamping plate 22 for clamping on the wall of the edge and opening 8 is fixedly arranged. When the L-shaped clamping plate 22 is buckled at the external angle of the edge and opening, the side plate fixedly connected to the telescopic sleeve rod 2 fits with the inner side wall of the edge and opening, and then the L-shaped clamping plate 22 is fixed by top pressure in the edge and opening. The other side plate not connected to the telescopic sleeve rod 2 is buckled on the wall outside the edge and opening. By using this side plate, the movement of the L-shaped clamping plate 22 towards the outside of the wall can be effectively blocked, and then the reliability of preventing high-altitude falls of the present invention at the edge and opening can be improved; at both the left and right ends of the main support pipe 1, a first top pressure mechanism is arranged, and the first top pressure mechanism is used to top pressure the corresponding telescopic sleeve rod 2 outwards. In practical applications, the telescopic sleeve rod 2 can be stably top pressured in the edge and opening by using the first top pressure mechanism, so as to realize the installation of the present invention at the edge and opening. When several groups of the present invention are installed along the up and down direction of the edge and opening, several groups of the present invention form a barrier with a certain height, and then the safety protection of the edge and opening is realized.
[0021] On the basis of the above embodiment, the specific implementation manner of the telescopic sleeve rod 2 for realizing free sliding adjustment at the end of the main support pipe 1 is: two stop rods 21 are arranged on the telescopic sleeve rod 2 and are distributed up and down. A guide chute 11 corresponding to the stop rod 21 is arranged on the side wall of the main support pipe 1. The stop rod 21 is sleeved in the corresponding guide chute 11. The outer end of the guide chute 11 is in a closed state, and then the stop rod 21 can be effectively prevented from sliding out of the main support pipe 1 from the guide chute 11, which is convenient for the operation and use of the present invention.
[0022] Based on the above embodiments, the specific implementation manner of the first pressing mechanism is as follows: Each group of the first pressing mechanisms includes a first pressing spring 32 and a first adjusting nut 31. A section of first external thread 12 is provided on both the left and right sides of the main support pipe 1. The first adjusting nut 31 is sleeved on the first external thread 12, and the first pressing spring 32 is sleeved on the main support pipe 1. The first pressing spring 32 is clamped between the corresponding first adjusting nut 31 and the stop lever 21. By rotating the first adjusting nut 31, its left and right movement on the main support pipe 1 is realized. The left and right movement of the first adjusting nut 21 realizes the compression and release of the first pressing spring 32. After the L-shaped clamping plate 22 is clamped on the wall, by continuously compressing the first pressing spring 32 with the first adjusting nut 31, the greater the pressing force obtained by the L-shaped clamping plate 22, so that the L-shaped clamping plate 22 can be pressed and fixed on the wall. Because the first pressing spring 32 has the characteristic of expansion and contraction, therefore, by pressing the stop lever 21 with the first pressing spring 32, the lasting and effective pressing of the L-shaped clamping plate 22 on the wall can be effectively ensured, and the installation stability of the utility model at the edge opening is improved; When the first adjusting nut 31 is adjusted in place, using the self-locking limit principle of thread fit, under the condition that the first adjusting nut 31 does not rotate, it cannot realize left and right movement, so as to ensure the lasting pressing effect on the L-shaped clamping plate 22; When it is necessary to release the pressing action of the L-shaped clamping plate 22 on the wall, rotate the first adjusting nut 31 to release its compression on the first pressing spring 32. After the first pressing spring 32 is not compressed, it loses the pressing on the stop lever 21, so that the telescopic sleeve rod 2 can retract. The retraction of the telescopic sleeve rod 2 drives the L-shaped clamping plate 22 to retract, thereby releasing the pressing of the L-shaped clamping plate 22 on the wall.
[0023] To further improve the installation stability of the present utility model at the edge opening and at the same time expand the upper and lower protection range of the present utility model within the edge opening, here, the protection device further includes an auxiliary pressing mechanism. The auxiliary pressing mechanism includes a vertical pressing rod 4, a first connecting rod 5, a second connecting rod 6, an auxiliary pressing block 7, and a second pressing mechanism. A vertical sleeve 13 is vertically and fixedly arranged in the middle of the main support pipe 1. The vertical pressing rod 4 is sleeved in the vertical sleeve 13 and can move up and down freely relative to the vertical sleeve 13. Vertical support ears 14 are fixedly arranged at the lower parts of the left end and the right end of the main support pipe 1 respectively. One end of the corresponding first connecting rod 5 is hinged to the vertical support ear 14. Two second connecting rods 6 distributed left and right are respectively arranged at the lower part of the vertical pressing rod 4, and the second connecting rod 6 is hinged to the horizontal support ear 41 at the lower part of the vertical pressing rod 4. The other ends of the corresponding first connecting rod 5 and the second connecting rod 6 on one side of the vertical pressing rod 4 are both hinged to a hinge shaft 71 on the corresponding auxiliary pressing block 7. The two second connecting rods 6 are distributed in a ∧ shape at the lower part of the vertical pressing rod 4. Because the two second connecting rods 6 are always distributed in a ∧ shape at the lower part of the vertical pressing rod 4, during the process of the vertical pressing rod 4 continuously moving vertically downward, the two auxiliary pressing blocks 7 will move away from each other under the action of the second connecting rods 6. Thus, in the actual application process, it is convenient to use the vertical pressing rod 4 to press and fix the two auxiliary pressing blocks 7 on the opposite inner side walls of the edge opening. The auxiliary pressing block 7 stably presses on the wall, and then the installation stability of the present utility model at the edge opening can be assisted to be improved. The second pressing mechanism is used to press the vertical pressing rod 4 downward. Further, the specific implementation manner of the second pressing mechanism is as follows: The second pressing mechanism includes a second pressing spring 82 and a second adjusting nut 81. A section of second external thread 131 is arranged at the lower part of the vertical sleeve 13. The second adjusting nut 81 is sleeved on the second external thread 131. The second pressing spring 82 is sleeved on the outer sides of the vertical sleeve 13 and the vertical pressing rod 4, and the second pressing spring 82 is clamped between the second adjusting nut 81 and the horizontal support ear 41. When the second adjusting nut 81 is rotated to continuously move downward, the second adjusting nut 81 continuously presses the second pressing spring 82. The second pressing spring 82 continuously pushes the vertical pressing rod 4 to move downward during the pressing process. As the vertical pressing rod 4 continuously moves downward, the two second connecting rods 6 continuously open, realizing the mutual separation and expansion of the two auxiliary pressing blocks 7. When the two auxiliary pressing blocks 7 contact the wall, by continuously moving the second adjusting nut 81 downward, the auxiliary pressing block 7 can obtain a larger pressing force, so as to realize the stable pressing and fixing of the auxiliary pressing block 7 on the wall. Then, the present utility model is stably installed in the edge opening through the pressing actions of the two auxiliary pressing blocks 7 and the two L-shaped clamping plates 22;After the second adjusting nut 81 is adjusted in place, based on the self-locking limit principle of screw thread fit, under the condition that the second adjusting nut 81 does not rotate, it cannot move up and down, thus ensuring the lasting pressing effect on the auxiliary pressing block 7. When it is necessary to release the pressing action of the auxiliary pressing block 7 on the wall, rotate the second adjusting nut 81 to release its compression on the second pressing spring 82. After the second pressing spring 82 is no longer compressed, it loses the pressing on the second connecting rod 6, so that the auxiliary pressing block 7 can swing inwards. When the auxiliary pressing block 7 swings inwards, its pressing action on the wall is then released.
[0024] In the actual application process, to increase the friction coefficient between the L-shaped clamping plate 22 and the auxiliary pressing block 7 and the corresponding wall, here, rubber pads are provided on the side surfaces of the auxiliary pressing block 7 and the L-shaped clamping plate 22 corresponding to the wall. The rubber pads have a large friction coefficient, which can facilitate increasing the frictional force between the L-shaped clamping plate 22 or the auxiliary pressing block 7 and the wall, and thus help improve the clamping stability of the auxiliary pressing block 7 and the L-shaped clamping plate 22 on the wall.
[0025] In the process of using the present utility model, to prevent the vertical pressing rod 4 from sliding out of the vertical sleeve 13, here, a limiting plate 42 is provided at the upper part of the vertical pressing rod 4. The limiting plate 42 is circular and its diameter is larger than the outer diameter of the vertical sleeve 13, which can effectively prevent the upper part of the vertical pressing rod 4 from entering the vertical sleeve 13, realizing the anti-dropping function of the vertical pressing rod 4.
[0026] Since the vertical distance between the L-shaped clamping plate 22 and the auxiliary pressing block 7 is relatively large, the upper and lower protection range of the present utility model is expanded. Then, when installing and protecting the edge opening 9, the number of the present utility model used can be relatively reduced, which can improve the construction efficiency of the protection work for the edge opening 9 to a certain extent.
[0027] In the present utility model, "up", "down", "front", "back", "left", and "right" are all relative positions used for conveniently describing the position relationship, so they cannot be understood as absolute positions to limit the protection scope.
[0028] Except for the technical features described in the specification, they are all known technologies to those skilled in the art.
[0029] As described above, the preferred embodiments and examples of the present utility model have been described in detail in conjunction with the drawings. However, the present utility model is not limited to the above embodiments and examples. For those of ordinary skill in the art in this technical field, without departing from the concept of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
