DETAILED DESCRIPTION

[0032] The following will be combined with specific embodiments and attached Figure 1-15 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the preferred embodiments of the present invention, rather than all the embodiments. Those skilled in the art can make similar modifications without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0033] The present invention provides a retractable modular protective shed (such as Figure 1As shown), it includes a main support structure and a main frame plate 6. After multiple main frame plates 6 are erected on the main support structure, safety protection of the top of the main support structure is realized. The main support structure includes a retractable support frame and a longitudinal connecting rod 5. Two groups of retractable support frames are relatively distributed front and back, and each group of retractable support frames includes a first support column 1, a second support column 2, a frame support rod 3, and an oblique support rod 4. The first support column 1 and the second support column 2 are relatively distributed left and right, and the two frame support rods 3 are relatively arranged at the upper part between the first support column 1 and the second support column 2. One end of the frame support rod 3 is hingedly connected to the side wall of the second support column 2 and cannot slide up and down relative to the second support column 2, that is, the connection of the frame support rod 3 The connecting end can swing up and down relative to the second support column 2 but cannot be adjusted by moving up and down. The other end of the shelf support rod 3 is hingedly connected to the side wall of the first support column 1 and can slide up and down and be positioned relative to the first support column 1. The connecting end of the shelf support rod 3 can not only swing up and down relative to the first support column 1, but also can move up and down and be fixed relative to the first support column 1. The two diagonal support rods 4 are arranged between the first support column 1 and the second support column 2. One end of the diagonal support rod 4 is hingedly connected to the side wall of the second support column 2 and cannot slide up and down relative to the second support column 2, that is, the connecting end of the diagonal support rod 4 can swing up and down relative to the second support column 2 but cannot be moved up and down. The other end of the diagonal brace rod 4 is hingedly connected to the side wall of the first support column 1 and can slide up and down and be positioned relative to the first support column 1, that is, the connection end of the diagonal brace rod 4 can not only swing up and down relative to the first support column 1, but also move up and down and be fixed relative to the first support column 1. By utilizing the above-mentioned connection relationship between the shelf support rod 3 and the diagonal brace rod 4 and the corresponding first support column 1 and the second support column 2, the first support column 1 and the second support column 2 can be retracted to approach each other. When the first support column 1 and the second support column 2 are retracted and approached, one end of the shelf support rod 3 and the diagonal brace rod 4 continuously slides on the first support column 1, thereby ensuring that the first support column 1 and the second support column 2 can smoothly approach each other. Contraction, the retractable support frame can be retracted, which is convenient for reducing the volume of the main support structure, and then it is convenient for the transfer and transportation of the present invention. A longitudinal connecting rod 5 is arranged between the two first support columns 1 and between the two second support columns 2. The longitudinal connecting rod 5 can realize the stable connection of the two groups of retractable support frames distributed front and back, and then ensure the overall structural strength of the main support structure. When the longitudinal connecting rod 5 is disassembled, the longitudinal contraction and storage of the main support structure can be realized. A plurality of main frame plates 6 are arranged between the two front and rear opposite frame plate support rods 3, and two layers of main frame plates 6 distributed up and down are arranged on the main support structure, so that the top protection ability of the protective shed can be greatly improved, and the main frame plates 6 adjacent to each other on the left and right are tightly fitted.This can effectively protect smaller objects from falling from high altitudes.

[0034] In the above embodiment, without disassembling the frame support rod 3 and the diagonal support rod 4, the first support column 1 and the second support column 2 opposite to each other can be moved closer and retracted to each other, thereby realizing the lateral contraction of the main support structure. Without disassembling the longitudinal connecting rod 5, the two first support columns 1 and the two second support columns 2 opposite to each other can also be moved closer and retracted to each other, so as to realize the longitudinal contraction of the main support structure. Here, one end of the longitudinal connecting rod 5 is hingedly connected to the side wall of the second support column 2 and cannot slide up and down relative to the second support column, that is, the longitudinal connecting rod 5 The connecting end can swing up and down relative to the second support column 2 but cannot move up and down, and the other end of the longitudinal connecting rod 5 is hingedly connected to the side wall of the first support column 1 and can slide up and down and be positioned relative to the first support column 1, that is, the connecting end of the longitudinal connecting rod 5 can not only swing up and down relative to the first support column 1, but also slide up and down and be fixed on the first support column 1. Specifically, a second T-shaped guide rail 15 is vertically arranged on the front side walls of the first support column 1 and the second support column 2 located at the rear side, and a sixth hinge seat 16 is slidably sleeved on the second T-shaped guide rail 15. The sixth hinge seat 16 is The T-shaped groove provided on the articulated seat 16 is sleeved on the second T-shaped guide rail 15, and a positioning bolt 101 is provided on the sixth articulated seat 16. The positioning bolt 101 can realize the positioning of the sixth articulated seat 16 on the second T-shaped guide rail 15. A seventh articulated seat 25 used in conjunction with the sixth articulated seat 16 is fixedly provided on the rear side wall of the first support column 1 and the second support column 2 located on the front side. One end of the longitudinal connecting rod 5 is articulatedly connected to the corresponding sixth articulated seat 16, and the other end of the longitudinal connecting rod 5 is articulatedly connected to the corresponding seventh articulated seat 25. In practical applications, One end of the longitudinal connecting rod 5 is T-shaped, and the T-shaped end is hinged on the sixth hinge seat 16. A ring is set at the other end of the longitudinal connecting rod 5, and the ring is hinged on the seventh hinge seat 25 by a pin shaft. During normal use, the longitudinal connecting rod 5 is placed horizontally. When it is necessary to fold and shrink, the locking position of the sixth hinge seat 16 by the positioning bolt 101 is released, and then the sixth hinge seat 16 is moved, which facilitates the mutual approach of the first support column 1 or the second support column 2 that are relatively distributed front and back, thereby realizing the longitudinal contraction of the main support structure without disassembling the longitudinal connecting rod 5.

[0035] During normal use of the present invention, in order to improve the stability of the present invention on the ground, a support reinforcement plate 17 is provided on the lower periphery of the first support column 1 and the second support column 2, and a plurality of through holes 171 are provided on the support reinforcement plate 17. After the positions of the first support column 1 and the second support column 2 are adjusted, expansion bolts are used to penetrate the through holes 171 to fix the support reinforcement plate 17 on the ground, thereby fixing the main support structure on the ground.

[0036] On the basis of the above embodiments, in order to facilitate the flexible adjustment of the installation position of the present invention, a walking wheel 18 that can be lifted up and down is provided at the bottom of the first support column 1 and the second support column 2. Specifically, a support plate 102 avoiding the top of the support reinforcement plate 17 is fixedly provided at the bottom of the first support column 1 and the second support column 2, and a support bolt 181 is fixedly provided on the upper part of the walking wheel 18. The support bolt 181 is vertically slidably sleeved on the support plate 102, and an adjusting nut 182 located below the support plate 102 is sleeved on the support bolt 181. In actual application, by changing the position of the adjusting nut 182 on the support bolt 181, the contact or separation of the bottom of the walking wheel 18 with the ground can be achieved. When the present invention needs to be moved, the walking wheel 18 is made to contact the ground. When the installation position of the present invention is determined, the walking wheel 18 can be separated from the ground, and then the support of the present invention is achieved by using the support reinforcement plate 17.

[0037] On the basis of the above-mentioned embodiment, the specific implementation method of connecting the shelf support rod 3 with the side walls of the first support column 1 and the second support column 2 is as follows: three first T-shaped guide rails 11 distributed front and back in sequence are vertically arranged on the right side wall of the first support column 1, a first hinge seat 12 is slidably sleeved on the first T-shaped guide rail 11 located in the middle, the T-shaped groove arranged on the first hinge seat 12 is sleeved on the corresponding first T-shaped guide rail 11, a first short hinge seat 121 and a first long hinge seat 122 are fixedly arranged on the upper and lower parts of the first hinge seat 12, and a second hinge seat 121 is fixedly arranged on the upper part of the left side wall of the second support column 2. A long hinge seat 21 and a second short hinge seat 22, a frame support rod 3 is hingedly arranged between the first short hinge seat 121 and the second long hinge seat 21, and a frame support rod 3 is hingedly arranged between the first long hinge seat 122 and the second short hinge seat 22. Specifically, a T-shaped rod can be arranged at one end of the frame support rod 3, and the T-shaped rod is sleeved in the corresponding first short hinge seat 121 or the first long hinge seat 122. A ring is arranged at the other end of the frame support rod 3, and the ring is sleeved in the corresponding second long hinge seat 21 or the second short hinge seat 22 by a pin shaft, and a positioning bolt 101 is arranged on the first hinge seat 12 When the first support column 1 and the second support column 2, which are relatively distributed on the left and right, need to be moved closer and contracted to each other, the locking of the first articulated seat 12 by the positioning bolt 101 is released, and when the first support column 1 and the second support column 2 are moved closer to each other, the first articulated seat 12 slides in real time on the first T-shaped guide rail 11; further, in order to prevent the shelf support rod 3 from affecting the sufficient close contraction of the first support column 1 and the second support column 2, here, when the shelf support rod 3 is in a vertically placed state, the distance between the outer side of the first long articulated seat 122 and the side wall of the first support column 1 is greater than the distance between the outer side wall of the corresponding shelf support rod 3 and the The distance between the side walls of the first support column 1, specifically, can make the distance between the outer side of the first long hinge seat 122 and the side wall of the first support column 1 larger by 3mm than the distance between the outer side wall of the corresponding shelf support rod 3 and the side wall of the first support column 1; the distance between the outer side of the second long hinge seat 21 and the side wall of the second support column 2 is larger than the distance between the outer side wall of the corresponding shelf support rod 3 and the side wall of the second support column 2, specifically, can make the distance between the outer side of the second long hinge seat 21 and the side wall of the second support column 2 larger by 3mm than the distance between the outer side wall of the corresponding shelf support rod 3 and the side wall of the second support column 2;That is, when designing the specific dimensions of the first long hinge seat 122, the second long hinge seat 21 and the shelf support rod 3, it is necessary to ensure that after the first long hinge seat 122 contacts the side wall of the second support column 2, the side wall of the shelf support rod 3 on the first long hinge seat 122 has not yet contacted the side wall of the second support column 2, and ensure that after the second long hinge seat 21 contacts the side wall of the first support column 1, the side wall of the shelf support rod 3 on the second long hinge seat 21 has not yet contacted the side wall of the first support column 1.

[0038] On the basis of the above-mentioned embodiment, the specific implementation method of the diagonal brace rod 4 to realize the connection with the first support column 1 and the second support column 2 is as follows: a second hinge seat 13 and a third hinge seat 14 are respectively arranged on the first T-shaped guide rail 11 located on the front side and the rear side, a positioning bolt 101 is arranged on the second hinge seat 13 and the third hinge seat 14, a fourth hinge seat 24 used in conjunction with the second hinge seat 13 is fixedly arranged on the lower part of the left side wall of the second support column 2, a diagonal brace rod 4 is hingedly arranged between the second hinge seat 13 and the fourth hinge seat 24, a T-shaped rod is arranged at one end of the diagonal brace rod 4, and a circular ring is arranged at the other end, the T-shaped rod is hinged on the second hinge seat 13, and the circular ring The ring is hingedly arranged on the fourth hinge seat 24 by a pin shaft, and a fifth hinge seat 23 used in conjunction with the third hinge seat 14 is fixedly arranged on the upper part of the left side wall of the second support column 2, and the diagonal support rod 4 is hingedly arranged between the third hinge seat 14 and the fifth hinge seat 13. By utilizing the sliding ability of the second hinge seat 13 and the third hinge seat 14 on the first T-shaped guide rail 11, one end of the diagonal support rod 4 can slide up and down, so that the diagonal support rod 4 will not affect the mutual approach and contraction between the first support column 1 and the second support column 2 relatively distributed on the left and right, and the corresponding second hinge seat 13 and the third hinge seat 14 can be fixed by the positioning bolt 101. Furthermore, the diagonal support The specific structure of the rod 4 is implemented as follows: the diagonal support rod 4 includes a threaded tube 41, a first threaded rod 42, and a second threaded rod 43. The first threaded rod 42 and the second threaded rod 43 are respectively sleeved on both ends of the threaded tube 41. The other end of the first threaded rod 42 is hingedly connected to the corresponding second hinge seat 13 or the third hinge seat 14, and the other end of the second threaded rod 43 is hingedly connected to the corresponding fourth hinge seat 24 or the fifth hinge seat 23. That is, a diagonal support rod 4 is arranged between the second hinge seat 13 and the fourth hinge seat 24, and a diagonal support rod 4 is arranged between the third hinge seat 14 and the fifth hinge seat 23. Rotating the threaded tube 41 can realize the connection between the first threaded rod 42 and the second threaded rod 43. As the threaded rods 43 move closer to or farther away from each other, the connection structure of the threaded tube 41 and the first threaded rod 42 and the second threaded rod 43 is the same as the connection structure of the existing turnbuckle screws. Therefore, the specific connection structure of the threaded tube 41 and the first threaded rod 42 and the second threaded rod 43 is not introduced in detail here. In actual application, after the first support column 1 and the second support column 2 are unfolded relative to each other, the second hinge seat 13 and the third hinge seat 14 are fixed, and then the threaded tube 41 is rotated to make the first threaded rod 42 and the second threaded rod 43 mutually in principle, thereby realizing the connection and tightening of the first support column 1 and the second support column 2, thereby improving the connection structure strength of the first support column 1 and the second support column 2.

[0039] On the basis of the above-mentioned embodiment, the specific implementation method of the frame plate support rod 3 to realize the clamping and positioning of the main frame plate 6 is as follows: a plug-in slot 32 is set on the frame plate support rod 3, and a frame plate entrance 31 is opened at one end of the plug-in slot 32. The plug-in slots 32 on the two frame plate support rods 3 distributed front and back are relatively distributed front and back, and the two ends of the main frame plate 6 are inserted into the corresponding plug-in slots 32. When the plug-in slots 32 are full of main frame plates 6, multiple main frame plates 6 form a protective layer. Because the first short hinge seat 121, the first long hinge seat 122, the second short hinge seat 22 and the second long hinge seat 21 have a certain length, there are certain protective loopholes above them. In order to facilitate the covering of the protective loopholes, a reinforcing frame plate 7 is set on the upper parts of the two first short hinge seats 121 distributed front and back, the upper parts of the two first long hinge seats 122, the upper parts of the two second long hinge seats 21 and the upper parts of the two second short hinge seats 22. By combining the main frame plate and the reinforcement frame plate 7, the gaps between the two first support columns 1 and the two second support columns 2 are completely covered, thereby improving the protection safety.

[0040] In practical applications, when the present invention needs to be retracted, stored and transferred, the reinforcement frame plate 7 and the main frame plate 6 can be removed first, and then all the positioning bolts 101 can be loosened to allow the corresponding hinged seats to slide. After all the positioning bolts 101 are loosened, the two groups of first support columns 1 and second support columns 2 opposite to each other can be retracted first, and then the two first support columns 1 and the two second support columns 2 opposite to each other can be retracted, and finally the overall retraction of the main support structure can be completed. The above-mentioned retraction operation method can greatly improve the efficiency of storage, transportation and transfer of the protective shed.

[0041] In the present invention, "up", "down", "front", "back", "left" and "right" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.

[0042] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.

[0043] The above description in combination with the accompanying drawings has detailed the preferred implementation modes and embodiments of the present invention, but the present invention is not limited to the above implementation modes and embodiments. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the concept of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
