Description

Technical Field

[0001] The present invention relates to the technical field of sealing devices, and particularly relates to a butt joint surface sealing structure and a military shelter. Background Art

[0002] Most of the top covers of military shelters adopt the single-side opening method. The single-side opening method has fewer sealing parts, high operability, and strong practicability. However, for large hatch covers with a length greater than 10 meters and a width greater than 3 meters, the single-side opening method has too high strength requirements for the support parts of the shelter, high implementation cost, and greatly reduced practicability. In this case, the double-side opening method needs to be adopted. The double-side opening method solves the problem of too high strength requirements, and the area of each side of the top cover is greatly reduced. During the movement of the military shelter, due to external factors such as road conditions, there is often a certain relative displacement at the butt joint surface in the double-side opening method. How to ensure the sealing performance of the butt joint part in this case has become an urgent problem to be solved. Summary of the Invention

[0011] A limiting block is movably arranged in the activity groove and can move to abut and be limited at the limiting openings; and,

[0012] A traction rope, the two ends of which are respectively connected to the limiting block and the second magnetic attraction part.

[0013] Optionally, the sealing part includes a "C"-shaped sealing strip.

[0031] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the attached drawings). If the specific posture changes, the directional indications will also change accordingly.

[0034] In addition, the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0035] Most military shelter tops use the single-side opening method. The single-side opening method has fewer sealing parts, high operability, and strong practicability. However, for large hatches with a length greater than 10 meters and a width greater than 3 meters, using the single-side opening method requires too high strength for the support parts of the shelter, with high implementation costs and a significant decline in practicability. In this case, the double-side opening method needs to be adopted. The double-side opening method solves the problem of excessive strength requirements, but the area of the top cover on each side is greatly reduced. During the movement of the military shelter, due to external factors such as road conditions, there is often a certain relative displacement at the docking surface in the double-side opening method. How to ensure the sealing performance of the docking part in this case has become an urgent problem to be solved.

[0036] To solve the above problems, the present invention proposes a docking surface sealing structure. Figure 1 This is an embodiment of the present invention. Figure 2 This is another embodiment of the military shelter of the present invention.

[0037] In the embodiment of the present invention (hereinafter referred to as this embodiment), the docking surface sealing structure 102 is as Figure 1 shown. The docking surface sealing structure 102 includes a first sealing seat 1, a second sealing seat 2, and a sealing structure 4. The first sealing seat 1 and the second sealing seat 2 are oppositely arranged and define an installation gap 3. The first sealing seat 1 and the second sealing seat 2 can move relative to each other. The sealing structure 4 forms a deformable sealing part 41. The sealing part 41 is arranged in the installation gap 3. One end of the sealing part 41 is sealingly connected to the first sealing seat 1, and the other end is sealingly connected to the second sealing seat 2 through a magnetic attraction structure 5.

[0038] In the technical solution of the present invention, a sealing portion 41 is provided in the installation gap 3 between the first sealing seat 1 and the second sealing seat 2, and one end of the sealing portion 41 is hermetically connected to the first sealing seat 1, and the other end connects the sealing portion 41 to the second sealing seat 2 through a magnetic attraction structure 5. When a relative displacement occurs within a small range between the first sealing seat 1 and the second sealing seat 2, the sealing portion 41 will deform and still maintain its connection with the second sealing seat 2, that is, when a certain relative displacement occurs between the first sealing seat 1 and the second sealing seat 2, the sealing structure 4 can still ensure the sealing of the installation gap 3.

[0039] To specifically implement the magnetic attraction structure 5 to seal the second sealing seat 2 with the sealing portion 41, the magnetic attraction structure 5 includes a first magnetic attraction portion 51 and a second magnetic attraction portion. The first magnetic attraction portion 51 is provided on the second sealing seat 2, and the second magnetic attraction portion is provided on the side end of the sealing portion 41 facing away from the first sealing seat 1. The first magnetic attraction portion 51 and the second magnetic attraction portion attract each other so that the sealing portion 41 presses on the first magnetic attraction portion 51 to complete the sealing of the installation gap 3. When a small relative movement occurs between the first sealing seat 1 and the second sealing seat 2, the first magnetic attraction portion 51 still attracts the second magnetic attraction portion, and the sealing portion 41 is deformed by extrusion to continuously seal the installation gap 3, where the first magnetic attraction portion 51 and the second magnetic attraction portion can be a pair of mutually attracting magnets, or one of them can be a magnet and the other can be a metal sheet attracted by the magnet.

[0040] To prevent the sealing portion 41 from being torn when the first mounting seat and the second mounting seat are relatively opened, the butt joint surface sealing structure 102 further includes a limit protection structure 6. The limit protection structure 6 is provided between the sealing portion 41 and the first sealing seat 1 and is used to limit the movement of the second magnetic attraction portion when the first sealing seat 1 and the second sealing seat 2 move away from each other, that is, when the two top covers of the shelter are relatively opened, so as to forcibly release the attracting state of the magnetic attraction structure 5 and prevent the second magnetic attraction portion from pulling the sealing portion 41, thereby enhancing the service life of the sealing portion 41.

[0041] To specifically implement the functions of the limit protection structure 6, the limit protection structure 6 includes a limit seat 61, a limit block 62, and a traction rope 63. The limit seat 61 extends from the first sealing seat 1 into the installation gap 3, and an activity groove 611 is provided in the limit seat 61. The two side walls of the activity groove 611 are bent inward at its mouth to form a limit opening 612. The limit block 62 is movably arranged in the activity groove 611 and can move to abut and be limited at the limit opening 612 to limit the activity range of the movable block through the limit opening 612. The two ends of the traction rope 63 are respectively connected to the limit block 62 and the second magnetic attraction part. When the first movable seat and the second movable seat move away from each other relatively, the second magnetic attraction part pulls the limit block 62 to move in the activity groove 611 through the traction rope 63 and finally abuts at the limit opening 612. At this time, the first mounting seat and the second mounting seat are still moving away from each other. Since the movable block abuts at the limit opening 612, the second magnetic attraction part is separated from the first magnetic attraction part 51 by the pulling force of the traction rope 63, preventing the second magnetic attraction part from continuously attracting the first magnetic attraction part 51 and causing the sealing part 41 to be pulled and damaged. Generally, to improve the strength of the traction rope, a steel wire rope can be used as the traction rope.

[0042] To specifically implement the sealing function of the sealing strip, the sealing part 41 includes a "C"-shaped sealing strip. The two ends of the "C"-shaped sealing strip are fixed on the first sealing seat 1 to seal the first sealing seat 1. The second magnetic attraction part is arranged in the "C"-shaped sealing strip to attract the first magnetic attraction part 51 mutually, so that the sealing strip is pressed on the first magnetic attraction part 51 of the second mounting seat. At the same time, the "C"-shaped sealing strip has a certain space margin, that is, it can be deformed to adapt to the small-range relative movement displacement between the first sealing seat 1 and the second sealing seat 2; the sealing part 41 can also be a sealing strip of other shapes as long as it has a certain floating space.

[0043] A first gap 7 connected to the installation gap 3 is further formed between the first sealing seat 1 and the second sealing seat 2. The first gap 7 extends in the up-down direction. To prevent rainwater from flowing into the interior of the shelter through the first gap 7, the sealing structure 4 further includes a covering structure 42. The covering structure 42 includes a covering portion 421 and a supporting portion 422. The covering portion 421 extends from the upper end of the second sealing seat 2 towards the upper end of the first sealing seat 1 to cover above the first gap 7, preventing rainwater from directly falling into the first gap 7. One end of the supporting portion 422 extends upward from the upper end of the first sealing seat 1 to abut against the covering portion 421 when the first sealing seat 1 and the second sealing seat 2 move closer to each other. This can not only support the covering portion 421 to prevent it from falling off but also prevent rainwater from flowing into the first gap 7 laterally. Further, reinforcing ribs are provided on the covering portion 421 to increase the self-strength of the covering portion 421.

[0044] To further prevent rainwater from entering the shelter, the other end of the supporting portion 422 extends downward from the first gap 7 to extend to the bottom of the installation gap 3 and is bent at this position to form a drainage groove 423. When rainwater still enters the first gap 7, it will fall into the drainage groove 423 and finally be discharged from the drainage groove 423. The supporting portion 422 can be a bent profile or made of other rigid materials.

[0045] To improve the sealing performance between the supporting portion 422 and the covering portion 421, the end of the supporting portion 422 adjacent to the covering portion 421 is covered with a sealing member 8 for sealing the gap between the supporting portion 422 and the covering portion 421. The sealing member 8 can be a rubber sleeve or a sealing strip, etc.; the end of the supporting portion 422 forming the drainage groove 423 is also provided with the sealing member 8 to prevent accidental injury to people due to gaps or sharpness at the end of the rigid material.

[0046] The present invention also proposes a military shelter 2000. The military shelter 2000 includes a shelter body 101 and a docking surface sealing structure 102. The shelter body 101 has two top covers that can be opened and closed relative to each other. The specific structure of the docking surface sealing structure 102 refers to the above embodiments. The first mounting seat and the second mounting seat of the docking surface sealing structure 102 are respectively installed on the docking surfaces of the two top covers. Since the military shelter 2000 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0047] Reference Figure 1, both the first sealing seat 1 and the second sealing seat 2 include "L" profiles and are arranged oppositely to form the laterally extending installation gap 3 and the first gap 7 extending in the up-and-down direction in the longitudinal section. In this solution, two installation methods of the "L" profile as shown in 1 and Figure 2 are provided for installing on the installation surface of the top cover. The connection installation method can adopt bonding plus threaded connection.

[0048] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
