This connection method aims to provide a stable transmission torque, ensure the reliability and safety of the connection, and facilitate disassembly and maintenance.

[0003] When the existing column end connecting device is docked with the bottom plate and the top plate, due to the failure to pre-position at the corners of the bottom plate or the top plate, the support column cannot quickly fit with the corners of the bottom plate and the top plate during installation, thus making the installation of the support column inconvenient. However, when the above device is connected to the boundary of the bottom plate and the top plate, it cannot... Therefore, the inventor provides a column end connecting device to solve the problems raised in the above background technique. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a column end connecting device to achieve the effect of convenient installation of the support column.

[0005] The purpose of the utility model can be realized by the following technical solutions:

[0006] A column end connecting device includes a support column. A top plate is arranged on one side of the support column. A connecting mechanism is arranged on the top of the support column. The connecting mechanism includes a boundary block. A movable cover plate is arranged on the top of the boundary block. Seventh threaded hole groups are respectively opened on the tops of the cover plate and the boundary block.

[0007] As a further scheme of the utility model: Third threaded hole groups are opened on the top of the support column. Installation grooves are opened on the left and right sides of the top of the support column. Installation blocks are fixedly connected to the left and right sides of the bottom of the boundary block.

[0008] As a further scheme of the utility model: Second bolt groups are arranged on the top of the cover plate; Corner grooves are opened at the corners of the top plate. Second threaded hole groups are opened on the tops of the corner grooves.

[0009] As a further scheme of the utility model: The cross-section of the installation groove is adapted to the size of the side surface of the installation block.

One side of the connecting spring is fixedly connected to the cover plate; A parallel plate is fixedly connected to one side of the cover plate. Flip plates that can be flipped are arranged on both sides of the parallel plate.

[0011] As a further solution of the present utility model: A pair of clamping blocks are respectively and fixedly connected to both sides of the parallel plate. A rotating rod is rotatably connected to one side of the clamping block. A turning plate is fixedly connected to the surface of the rotating rod. A return spring is fixedly connected to the inner side of the turning plate, and the inner side of the return spring is fixedly connected to the parallel plate; A positioning groove is formed in the front surface of the sliding block.

[0013] As a further solution of the present utility model: The turning plate is designed in an arc shape that gradually becomes higher from front to back.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] For this column end connection device, place the corner of the top plate into the interior of the boundary block, and the corner of the top plate fits with the interior of the boundary block. Then, close the cover plate in the above - mentioned manner so that the corner of the top plate is covered by the cover plate. At this time, the second threaded hole group, the third threaded hole group, and the two seventh threaded hole groups are corresponding. Finally, fix the top plate and the support column completely by threading the second bolt group with the above - mentioned threaded hole groups. Place the corner of the top plate into the interior of the boundary block, and the corner of the top plate fits with the interior of the boundary block. Then, slide the cover plate forward so that the cover plate slides along the interior of the guiding groove, and at the same time compress the connecting spring until the outer ends of the two turning plates contact the interior of the positioning groove. Thus, the contact force causes the two turning plates to turn inward and drive the return spring to compress at the same time. Then, the parallel plate and the turning plate pass through the positioning groove. After that, since the return spring loses the pressing force, the return spring drives the turning plate to turn outward and block outside the positioning groove. At this time, the seventh threaded hole group on the cover plate corresponds to the seventh threaded hole group on the boundary block to close the cover plate and cover the corner of the top plate. At this time, the second threaded hole group, the third threaded hole group, and the two seventh threaded hole groups are corresponding. Finally, fix the top plate and the support column completely by threading the second bolt group with the above - mentioned threaded hole groups. The cooperation of the above - mentioned structure achieves the effect of facilitating the installation of the support column.

[0016] In addition, for this column end connection device, when the connection mechanism needs to be connected to the corner of the top plate, usually, the top plate is lifted by a crane and then placed inside the boundary block. If the cover plate is not a removable design, then the top plate can only be inserted from the side of the boundary block, which is more difficult. Therefore, a movable cover plate is designed here. When the cover plate slides out, by pressing the two turning plates, the two turning plates cannot cover the positioning groove. Then, the connecting spring rebounds to drive the parallel plate and the cover plate to move backward, exposing the top of the boundary block, thus achieving the effect of facilitating the connection between the top plate and the connection mechanism.

Detailed implementation method

[0022] As Figure 1 shown, a column end connection device includes a support column 10, and a top plate 12 is arranged on the left side of the top of the support column 10, and a connection mechanism 30 is arranged on the top of the support column 10.

[0023] During use, the top of the support column 10 is fixed to the corner of the top plate 12 through the connection mechanism 30. Thus, the effect of forming the top of the building frame is achieved.

[0024] Referring to Figures 1-4 , a third threaded hole group 101 is opened at the top of the support column 10, and installation grooves 102 are opened on the left and right sides of the top of the support column 10; the connection mechanism 30 includes a boundary block 302, and installation blocks 103 are fixedly connected to the left and right sides of the bottom of the boundary block 302; a movable cover plate 304 is installed on the top of the boundary block 302, seventh threaded hole groups 303 are respectively opened on the tops of the cover plate 304 and the boundary block 302, and a second bolt group 301 is arranged on the top of the cover plate 304.

[0025] Preferably, the cross-section of the installation groove 102 is adapted to the side size of the installation block 103; during use, the boundary block 302 is fixed to the support column 10 by inserting the installation block 103 into the installation groove 102, and at the same time, the third threaded hole group 101 corresponds to the seventh threaded hole group 303 on the boundary block 302;

[0026] Specifically, a sliding block 305 is fixedly connected to the right side of the boundary block 302. A guiding groove 306 is formed inside the sliding block 305. A connecting spring 307 is fixedly connected to the front side inside the guiding groove 306. The rear side of the connecting spring 307 is fixedly connected to the cover plate 304. A parallel plate 309 is fixedly connected to the front surface of the cover plate 304. A pair of clamping blocks 310 are respectively fixedly connected to the upper and lower sides of the parallel plate 309. A rotating rod 311 is rotatably connected to the inner side of the same-side clamping blocks 310. A turning plate 312 is fixedly connected to the surface of the rotating rod 311. A return spring 313 is fixedly connected to the inner side of the turning plate 312. The inner side of the return spring 313 is fixedly connected to the parallel plate 309. A positioning groove 308 is formed in the front surface of the sliding block 305.

[0027] Preferably, the sliding block 305 is made of stainless steel. Since the sliding block 305 is arranged at the outer end, the stainless steel material will not rust under sun and rain, which can better protect the internal structure.

[0028] Preferably, the turning plate 312 is designed in an arc shape that gradually becomes higher from front to back. When the surface of the turning plate 312 contacts the surface of the positioning groove 308, the turning plate 312 turns inward by force.

[0029] After manufacturing, the cover plate 304 can be slid forward, so that the cover plate 304 slides inside the guiding groove 306, and at the same time the connecting spring 307 is compressed until the outer ends of the two turning plates 312 contact the inside of the positioning groove 308. Thus, the contact force causes the two turning plates 312 to turn inward and drives the return spring 313 to be compressed at the same time. Then the parallel plate 309 and the turning plate 312 pass through the positioning groove 308. Then, since the return spring 313 loses the pressing force, the return spring 313 drives the turning plate 312 to turn outward and block outside the positioning groove 308, so as to facilitate the taking of the connecting mechanism 30. And at this time, the seventh threaded hole group 303 on the cover plate 304 corresponds to the seventh threaded hole group 303 on the boundary block 302.

[0030] When the connecting mechanism 30 needs to be connected to the corner of the top plate 12, usually, the top plate 12 is lifted by a crane and then placed inside the boundary block 302. If the cover plate 304 is not a design that can be removed, then the top plate 12 can only be inserted from the side of the boundary block 302, which is difficult. Therefore, a movable cover plate 304 is designed here. When the cover plate 304 slides out, by pressing the two turning plates 312, the two turning plates 312 cannot cover the positioning groove 308. Then, the connecting spring 307 rebounds to drive the parallel plate 309 and the cover plate 304 to move backward, exposing the top of the boundary block 302, so as to facilitate the connection between the top plate 12 and the connecting mechanism 30.

[0031] Reference Figure 1, corner grooves 121 are provided at the corners of the top plate 12, and second threaded hole groups 122 are provided at the tops of the corner grooves 121; during use, place the corners of the top plate 12 into the interior of the boundary block 302, and make the corners of the top plate 12 fit with the interior of the boundary block 302. Then, close the cover plate 304 in the above manner so that the corners of the top plate 12 are covered by the cover plate 304. At this time, the second threaded hole groups 122, the third threaded hole groups 101, and the two seventh threaded hole groups 303 are corresponding. Finally, fix the top plate 12 and the support column 10 completely by screwing the second bolt group 301 with the above-mentioned threaded hole groups. Place the corners of the top plate 12 into the interior of the boundary block 302, and make the corners of the top plate 12 fit with the interior of the boundary block 302. Then, slide the cover plate 304 forward so that the cover plate 304 slides along the interior of the guide groove 306, and at the same time compress the connecting spring 307 until the outer ends of the two turning plates 312 contact the interior of the positioning groove 308. Thus, the contact force causes the two turning plates 312 to turn inward and drive the return spring 313 to compress at the same time. Then, the parallel plate 309 and the turning plates 312 pass through the positioning groove 308. After that, since the return spring 313 loses the pressing force, the return spring 313 drives the turning plates 312 to turn outward and block outside the positioning groove 308. At this time, the seventh threaded hole groups 303 on the cover plate 304 correspond to the seventh threaded hole groups 303 on the boundary block 302 to close the cover plate 304 so that the corners of the top plate 12 are covered by the cover plate 304. At this time, the second threaded hole groups 122, the third threaded hole groups 101, and the two seventh threaded hole groups 303 are corresponding. Finally, fix the top plate 12 and the support column 10 completely by screwing the second bolt group 301 with the above-mentioned threaded hole groups.

[0032] Working principle of the utility model: During use, place the corners of the top plate 12 into the interior of the boundary block 302, and make the corners of the top plate 12 fit with the interior of the boundary block 302. Then, close the cover plate 304 in the above manner so that the corners of the top plate 12 are covered by the cover plate 304. At this time, the second threaded hole group 122, the third threaded hole group 101, and the two seventh threaded hole groups 303 are corresponding. Finally, fix the top plate 12 and the support column 10 completely by threading the second bolt group 301 with the above-mentioned threaded hole groups. Place the corners of the top plate 12 into the interior of the boundary block 302, and make the corners of the top plate 12 fit with the interior of the boundary block 302. Then, slide the cover plate 304 forward so that the cover plate 304 slides along the interior of the guide groove 306, and at the same time compress the connecting spring 307 until the outer ends of the two turning plates 312 contact the interior of the positioning groove 308. Thus, the contact force causes the two turning plates 312 to turn inward and drives the return spring 313 to be compressed. Then, the parallel plate 309 and the turning plates 312 pass through the positioning groove 308. After that, since the return spring 313 loses the pressing force, the return spring 313 drives the turning plates 312 to turn outward and block outside the positioning groove 308. At this time, the seventh threaded hole group 303 on the cover plate 304 corresponds to the seventh threaded hole group 303 on the boundary block 302 to close the cover plate 304 so that the corners of the top plate 12 are covered by the cover plate 304. At this time, the second threaded hole group 122, the third threaded hole group 101, and the two seventh threaded hole groups 303 are corresponding. Finally, fix the top plate 12 and the support column 10 completely by threading the second bolt group 301 with the above-mentioned threaded hole groups.
