Description

Technical Field

[0001] The utility model relates to the technical field of connection mechanisms, in particular to a quick-assembly type spanning frame connection mechanism. Background Technique

[0002] A spanning frame is a component used to span various areas, commonly found in high-voltage power lines, railways, highways, rivers, deep valleys, etc. It is an important component of facilities such as high-voltage power lines, railways, and highways. It can be made of various materials such as steel pipes, angle steels, and channel steels. Its main function is to safely span facilities such as electric wires, railways, or roads to a designated area.

[0003] In the past, bamboo frames were usually used to build spanning frames, and later prefabricated iron frames were used as spanning frames. However, when assembling prefabricated iron frames, additional tools such as wrenches and screwdrivers were required, resulting in a more complex assembly process. In order to optimize the assembly process between spanning frames; for this reason, we provide a quick-assembly type spanning frame connection mechanism to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a quick-assembly type spanning frame connection mechanism, which can realize the quick assembly of multiple spanning frames and ensure the stability of the splicing part at the same time.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A quick-assembly type spanning frame connection mechanism, including a spanning frame body. Two groove mechanisms are provided at the top end of the spanning frame body, and two buckle mechanisms are provided at the bottom end of the spanning frame body.

Four guiding grooves are fixedly connected to the inner bottom wall of the first cavity. A limiting rod is slidably sleeved on the inner wall of each guiding groove. One end of each limiting rod is rotatably connected to a connecting column. The four connecting columns are respectively slidably connected to the inner walls at the four corners of the prefabricated turntable.

[0006] Furthermore, a slot and a second cavity are opened inside the assembly groove. Four sliding grooves are opened on the inner wall of the first cavity. The first cavity is communicated with the slot through the four sliding grooves. The four limiting rods are respectively slidably connected to the inner walls of the four sliding grooves.

A worm gear is fixedly connected to the bottom end of the rotating rod. A worm is rotatably sleeved on the inner wall of the second cavity. The worm gear meshes with the worm. By setting the cooperation between the worm gear and the worm, the rotating rod can be limited. If you want to rotate the rotating rod, it can only be achieved by rotating the worm.

[0008] Furthermore, both rotating shafts of the worm penetrate through the second cavity and are fixedly connected with handles. Anti-slip patterns are provided on the outer surface of each handle. By setting the handles, it is convenient to rotate the worm and improve the convenience during use.

[0009] Furthermore, the buckling mechanism includes a splicing buckle fixedly connected to the bottom end of the spanning frame body.

DETAILED DESCRIPTION OF THE EMBODIMENT

[0023] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0024] As described in the background art, in order to optimize the assembly process, this embodiment provides a quick-assembling type span frame connecting mechanism. The device can achieve quick assembly while ensuring the stability of the assembly, improving the practicality of the device.

[0025] See Figures 1 to 7, this embodiment proposes a quick-assembly type spanning frame connection mechanism, including a spanning frame body 1. There are two groove mechanisms 2 provided at the top end of the spanning frame body 1, and two buckle mechanisms 3 provided at the bottom end of the spanning frame body 1.

[0026] The groove mechanism 2 includes an assembly groove 201 fixedly connected to the top end of the spanning frame body 1. A first cavity 203 is opened inside the assembly groove 201, and the position of the first cavity 203 is as Figure 4 shown.

[0027] A rotating rod 205 is rotatably sleeved on the inner wall of the first cavity 203. A prefabricated turntable 206 is fixedly connected to the top end of the rotating rod 205. When the rotating rod 205 rotates, it will drive the prefabricated turntable 206 to rotate. The shape of the prefabricated turntable 206 is as Figure 5 shown. Reserved slots are opened at the four corners of the prefabricated turntable 206.

[0028] Four guiding grooves 207 are fixedly connected to the inner bottom wall of the first cavity 203. A limiting rod 208 is slidably sleeved on the inner wall of each guiding groove 207, and the limiting rod 208 can move in the inner wall of the corresponding guiding groove 207.

[0029] One end of each limiting rod 208 is rotatably connected to a connecting column 209. The four connecting columns 209 are respectively slidably connected to the inner walls at the four corners of the prefabricated turntable 206. By arranging the four connecting columns 209, the four limiting rods 208 can be respectively connected to the reserved slots at the four corners of the prefabricated turntable 206.

[0030] An insertion slot 202 and a second cavity 204 are opened inside the assembly groove 201. Four sliding grooves 210 are opened on the inner wall of the first cavity 203. The first cavity 203 is communicated with the insertion slot 202 through the four sliding grooves 210. The four limiting rods 208 are respectively slidably connected to the inner walls of the four sliding grooves 210.

[0031] By opening the sliding grooves 210, it is convenient for the limiting rods 208 to extend into the insertion slot 202, thereby facilitating the work of limiting other components.

[0032] The bottom end of the rotating rod 205 penetrates through the first cavity 203 and extends into the interior of the second cavity 204. A worm gear 211 is fixedly connected to the bottom end of the rotating rod 205. A worm 212 is rotatably sleeved on the inner wall of the second cavity 204. The worm gear 211 meshes with the worm 212.

[0033] By arranging the meshing between the worm gear 211 and the worm 212, the effects of speed reduction and self-locking can be achieved. The self-locking effect can limit the rotating rod 205. If you want the rotating rod 205 to rotate, it can only be achieved by rotating the worm 212. When the worm 212 rotates, it will drive the worm gear 211 to rotate. Through the rotation of the worm gear 211, the rotating rod 205 will rotate.

[0034] Next, the rotating rod 205 drives the prefabricated turntable 206 to rotate. When the prefabricated turntable 206 rotates, it drives the four limiting rods 208 to move simultaneously in the corresponding guide grooves 207 through the connecting columns 209 slidably connected at the four corners. Therefore, through the four sliding grooves 210, the four limiting rods 208 can be simultaneously inserted into the slot 202.

[0035] Both rotating shafts of the worm 212 penetrate through the second cavity 204 and are fixedly connected with a handle 4. Anti-slip patterns are provided on the outer surface of each handle 4. By setting the handle 4, it is convenient to rotate the worm 212 and improve the convenience during use.

[0036] The buckling mechanism 3 includes a splicing buckle 301 fixedly connected to the bottom end of the spanning frame body 1. A plug 302 is fixedly connected to the bottom surface of the splicing buckle 301. The size value of the plug 302 corresponds to the size value of the slot 202. By limiting the relationship between the sizes of the plug 302 and the slot 202, the plug 302 can be inserted into the slot 202, facilitating the splicing work between multiple spanning frame bodies 1.

[0037] Four limiting grooves 303 are provided on the outer surface of the plug 302. The positions of the four limiting grooves 303 correspond to the positions of the four sliding grooves 210 respectively. By limiting the positional relationship between the sliding groove 210 and the limiting groove 303, it is convenient to achieve the stable splicing work between multiple spanning frame bodies 1 through the limiting groove 303.

[0038] Through the above limitations, when multiple spanning frame bodies 1 are assembled, the two plugs 302 at the bottom end of one spanning frame body 1 can be respectively inserted into the two splicing grooves 201 at the top end of another spanning frame body 1. The two plugs 302 will be respectively inserted into the slots 202 opened on the upper surface of the corresponding splicing grooves 201, and the four limiting grooves 303 on the surface of the plug 302 respectively correspond to the positions of the four sliding grooves 210.

[0039] Then rotate the handle 4 at the top end of another spanning frame body 1. When the handle 4 rotates, it drives the corresponding worm 212 to rotate, so that the four limiting rods 208 simultaneously extend outwards and respectively penetrate into the corresponding limiting grooves 303 through the corresponding sliding grooves 210, realizing the four-directional limitation of the plug 302, thus completing the rapid assembly between the two groove mechanisms 2 and ensuring the stability of the assembly part.

[0040] The size values of the four limiting rods 208 respectively correspond to the size values of the four limiting grooves 303. By limiting the size relationship between the limiting rod 208 and the limiting groove 303, the limiting rod 208 can be inserted into the limiting groove 303, thereby realizing the stable assembly between multiple spanning frame bodies 1.

[0041] Working principle: Here, the quick assembly method between two cross-span body 1s is used to illustrate how to achieve the quick assembly between multiple cross-span body 1s. First, place the first cross-span body 1 below, then place the second cross-span body 1 above the first cross-span body 1 and adjust the orientation. Next, insert the two plug blocks 302 at the bottom end of the second cross-span body 1 into the assembly slots 201 at the top end of the first cross-span body 1 respectively. At this time, the plug blocks 302 will pass through the slots 202 opened above the corresponding assembly slots 201 to complete the insertion process. When inserted to the bottom, the orientations of the four limiting slots 303 opened on the outer surface of the plug block 302 will respectively correspond to the orientations of the four sliding slots 210 opened on the inner wall of the first cavity 203. Then rotate the handle 4 outside the assembly slot 201 at the top end of the first cross-span body 1. When the handle 4 rotates, it will drive the corresponding worm 212 to rotate. When the worm 212 rotates, it will drive the corresponding worm gear 211 to rotate and drive the prefabricated turntable 206 to rotate through the rotating rod 205. When the prefabricated turntable 206 rotates, it will make the four limiting rods 208 move along the corresponding guiding slots 207 respectively through the connecting columns 209 slidably connected at the four corners. In this way, the four limiting rods 208 can be simultaneously extended outwards. Then the four limiting rods 208 will respectively extend out from the inside of the first cavity 203 through the corresponding sliding slots 210 until the four limiting rods 208 are respectively inserted into the corresponding limiting slots 303 to achieve the limit in four orientations, thus completing the quick splicing work between the groove mechanism 2 and the buckle mechanism 3. In this way, the staff can repeat the above steps to quickly splice multiple cross-span body 1s through the groove mechanism 2 and the buckle mechanism 3. At the same time, the device realizes the stable connection between multiple cross-span body 1s through the limit in four directions, improving the practicability of the device. When disassembly is required, only need to rotate the handle 4 in the reverse direction to make the four limiting rods 208 move out of the corresponding limiting slots 303 respectively, and the effect of quick disassembly can be achieved.
