Description

Technical Field

[0001] This utility model relates to the field of space capsule technology, specifically to a detachable load-bearing space capsule keel support device. Background Technology

[0002] The orbital module, also known as the space capsule, is where astronauts work and live after the spacecraft enters orbit. In addition to food, water and waste collection devices, the module also contains instruments and equipment for space applications and scientific experiments. Some accommodation facilities also imitate space capsule-style houses for people to live in.

[0003] Application number CN202420655506.5 discloses a keel frame structure for a spacecraft, involving an upper support frame, a lower support frame, and support poles. The upper support frame has four connecting slots arranged in a rectangular array at its top. Two fixing plates are fixedly connected to the left and right sides of the inner wall of the upper support frame, mirror images of each other. Bolts are installed inside the fixing plates. Locking mechanisms are installed on the upper and lower sides of the outer wall of the support poles. Reinforcing plates are fixedly connected to the left and right sides of the inner wall of the upper support frame, mirror images of each other. A support crossbar is fixedly connected to the middle of the inner wall of the upper support frame. Connecting rods are movably connected to the left and right sides of the inside of the support crossbar. The upper and lower support frames have identical structures and are mirror images of each other. This invention uses bolts to thread the fixing plates to the inside of the socket, and by inserting a fixing block along the socket, the insertion rod is inserted into the positioning hole, thereby locking the bolts.

[0004] However, sometimes in order to save space, it is necessary to stack two spacecraft together, so that the spacecraft on the lower layer has to bear the entire weight of the spacecraft on the upper layer. The device, which only has four support poles, is not enough to support the upper spacecraft and is prone to breakage of the support poles. In order to strengthen the support strength of the spacecraft keel, a detachable load-bearing spacecraft keel support device is proposed. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a detachable load-bearing space capsule keel support device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a detachable load-bearing space capsule keel support device, including an upper support frame and a lower support frame. A support column is vertically arranged between the upper support frame and the lower support frame. There are four support columns. A second slot is opened on opposite sides of the lower support frame. A first slot is opened on opposite sides of the upper support frame. The second slot is used for the bottom end of the insert plate and the reinforcing column to be installed and inserted. The first slot is used for the insert block to be installed and inserted. The top end of the reinforcing column is fixedly connected to the bottom end of the column cap. The insert block is located at the top end of the column cap. The reinforcing column is vertically arranged between the insert plate and the column cap.

[0007] By adopting the above technical solution, the vertical positioning of the reinforcing column is ensured by the precise insertion of the insert plate into the second slot and the insert block into the first slot. Combined with the four-point support of the supporting column, the stability of the overall structure is significantly improved. At the same time, the linkage design of the first baffle and the spring can automatically reset and cover the second bolt. After the second baffle is locked by the magnetic block, it covers the first bolt. The double anti-loosening mechanism effectively prevents the bolt from loosening due to vibration or load, reduces maintenance needs, and extends service life.

[0008] Specifically, the top surface of the lower support frame is provided with a second bolt hole. There are multiple second bolt holes, which are located above the second slot. The second bolt holes are used for the insertion of the second bolt.

[0009] By adopting the above technical solution, after the insert plate is inserted into the second slot, the second bolt hole is aligned with the corresponding hole on the insert plate, and the second bolt is screwed in vertically to lock the insert plate through the lower support frame, ensuring a rigid connection between the insert plate and the lower support frame and preventing lateral displacement.

[0010] Specifically, the reinforcing column has first sliding grooves on both sides, and a slider is slidably installed inside the first sliding groove. One end of the slider is fixedly connected to one end of the first baffle.

[0011] By adopting the above technical solution, before tightening the second bolt, the first baffle needs to be pushed to slide along the first groove. The slider drives the first baffle to move backward, exposing the blocked second bolt hole and providing operating space for bolt installation. After the bolt is fixed, the baffle is released to reset and cover the second bolt hole.

[0012] Specifically, one side of the first groove is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to one side of the slider.

[0013] By adopting the above technical solution, when the first baffle is pushed, the slider compresses the spring to store energy; after it is released, the spring pushes the slider back to the initial position, causing the first baffle to automatically reset, completely covering the head of the second bolt, forming an anti-loosening protective layer, and preventing the bolt from falling off due to vibration.

[0014] Specifically, the inside of the column cap is provided with a second sliding groove, the inside of the second sliding groove is used for the sliding installation of the second baffle, one end of the second baffle is provided with a magnetic block, the magnetic block is magnetically connected to the inner side of the second sliding groove, and the other end of the second baffle is provided with a finger groove. Both the second sliding groove and the second baffle are provided with two sets.

[0015] Specifically, the bottom end of the column cap is provided with a first bolt hole, and there are multiple first bolt holes for inserting a first bolt.

[0016] By adopting the above technical solution, when it is necessary to fix the column cap, the second baffle is pulled outward through the finger groove, so that it slides out along the second slide groove, exposing the first bolt hole at the bottom of the column cap. The first bolt is passed through the first bolt hole of the column cap and screwed into the bottom of the upper support frame to achieve a tight connection between the column cap and the upper support frame. When the second baffle slides out, the bolt hole is exposed for easy operation. After sliding back, it covers the bolt head to prevent loosening. When the second baffle is pushed back, the magnetic block is attracted and locked to the inner wall of the slide groove. The second baffle covers the first bolt to prevent loosening.

[0017] The beneficial effects of this utility model are:

[0018] The detachable load-bearing space capsule keel support device described in this utility model ensures the vertical positioning of the reinforcing column through the precise insertion of the insert plate into the second slot and the insert block into the first slot. Combined with the four-point support of the support column, it significantly improves the stability of the overall structure. At the same time, the linkage design of the first baffle and the spring can automatically reset and cover the second bolt. After the second baffle is locked by the magnetic block, it covers the first bolt. The double anti-loosening mechanism effectively prevents the bolt from loosening due to vibration or load, reduces maintenance needs, and extends service life. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] As one embodiment of this utility model, such as Figures 1-4 As shown, the detachable load-bearing space capsule keel support device of this utility model includes an upper support frame 1 and a lower support frame 5. A support column 3 is vertically arranged between the upper support frame 1 and the lower support frame 5. There are four support columns 3. A second slot 4 is opened on opposite sides of the lower support frame 5. A first slot 2 is opened on opposite sides of the upper support frame 1. The second slot 4 is used for the bottom end of the insert plate 7 and the reinforcing column 6 to be installed and inserted. The first slot 2 is used for the insert block 10 to be installed and inserted. The top end of the reinforcing column 6 is fixedly connected to the bottom end of the column cap 9. The insert block 10 is located at the top end of the column cap 9. The reinforcing column 6 is vertically arranged between the insert plate 7 and the column cap 9.

[0027] When using the reinforcing column 6, insert the insert plate 7 precisely into the second slot 4 of the lower support frame 5, and at the same time, insert the insert block 10 on the top of the column cap 9 into the first slot 2 of the upper support frame 1, so that the reinforcing column 6 is vertically fixed between the upper support frame 1 and the lower support frame 5. The bottom of the column cap 9 fits against the bottom surface of the upper support frame 1 to provide support. The verticality and stability of the overall structure are ensured by the limiting of the slot.

[0028] The present invention also includes a second bolt hole 21 provided on the top surface of the lower support frame 5. The second bolt hole 21 is provided in multiple locations, and the multiple second bolt holes 21 are located above the second slot 4. The second bolt hole 21 is used for the second bolt 19 to be installed and inserted.

[0029] When in use, after the insert plate 7 is inserted into the second slot 4, the second bolt hole 21 is aligned with the corresponding hole on the insert plate 7, and the second bolt 19 is screwed in vertically to lock the insert plate 7 through the lower support frame 5, ensuring a rigid connection between the insert plate 7 and the lower support frame 5 and preventing lateral displacement.

[0030] The present invention also includes that the reinforcing column 6 has a first sliding groove 12 on both sides, and a slider 17 is slidably installed inside the first sliding groove 12, and one end of the slider 17 is fixedly connected to one end of the first baffle 8.

[0031] When in use, before tightening the second bolt 19, the first baffle 8 needs to be pushed to slide along the first slide groove 12. The slider 17 drives the first baffle 8 to move backward, exposing the second bolt hole 21 that was covered, providing operating space for bolt installation. After the bolt is fixed, the baffle is loosened to reset and cover the second bolt hole 21.

[0032] The present invention further includes that one side of the inner side of the first groove 12 is fixedly connected to one end of the spring 18, and the other end of the spring 18 is fixedly connected to one side of the slider 17.

[0033] When in use, when the first baffle 8 is pushed, the slider 17 compresses the spring 18 to store energy; after being released, the spring 18 pushes the slider 17 back to the initial position, causing the first baffle 8 to automatically reset, completely covering the head of the second bolt 19, forming an anti-loosening protective layer to prevent the bolt from falling off due to vibration.

[0034] The present invention also includes a second sliding groove 20 inside the column cap 9, the interior of the second sliding groove 20 being used for the sliding installation of the second baffle 11, a magnetic block 15 being provided at one end of the second baffle 11, the magnetic block 15 being magnetically connected to the inner side of the second sliding groove 20, and a finger groove 14 being provided at the other end of the second baffle 11, and two sets of the second sliding groove 20 and the second baffle 11 are provided.

[0035] This utility model also includes a first bolt hole 16 at the bottom end of the column cap 9. The first bolt hole 16 is provided in multiple locations, and the multiple first bolt holes 16 are used for the insertion of the first bolt 13.

[0036] When it is necessary to fix the column cap 9 during use, the second baffle 11 is pulled outward through the finger groove 14 so that it slides out along the second slide groove 20, exposing the first bolt hole 16 at the bottom of the column cap 9. The first bolt 13 is passed through the first bolt hole 16 of the column cap 9 and screwed into the bottom of the upper support frame 1 to achieve a tight connection between the column cap 9 and the upper support frame 1. When the second baffle 11 slides out, the bolt hole is exposed for easy operation. When it slides back, it covers the bolt head to prevent loosening. When the second baffle 11 is pushed back, the magnetic block 15 is attracted and locked to the inner wall of the slide groove. The second baffle 11 covers the first bolt 13 to prevent loosening.

[0037] When using this invention, if the reinforcing column 6 needs to be installed on the keel frame of the spacecraft, first align the insert plate 7 with the second slot 4 and the insert block 10 with the first slot 2 and insert them in, so that the reinforcing column 6 can be vertically positioned between the upper support frame 1 and the lower support frame 5, and the column cap 9 can support the bottom surface of the upper support frame 1. Then push the first baffle 8, thereby pushing the slider 17 in the first slide groove 12 towards the spring 18 and compressing the spring 18. At this time, the second bolt hole 21 is exposed. The second bolt 19 is screwed into the second bolt hole 21 and the interior of the insert plate 7 to fix the position of the insert plate 7. After screwing in, release the push on the first baffle 8, and the spring 18 will push the slider 17 to In its original position, the first baffle 8 can block the second bolt hole 21, thereby preventing the second bolt 19 from retracting. Then, a finger is placed in the finger groove 14 and the second baffle 11 is pulled out of the second slide groove 20 by a certain distance, so that the second baffle 11 will not block the first bolt hole 16. The first bolt 13 is screwed into the first bolt hole 16 and into the bottom end of the upper support frame 1, thereby fixing the column cap 9. Then, the second baffle 11 is pushed into the second slide groove 20, and the magnetic block 15 at one end of the second baffle 11 is attracted to the inner side of the second slide groove 20 to fix the second baffle 11, thereby allowing the second baffle 11 to provide a function to prevent the first bolt 13 from retracting.
