[0040] Embodiment 1

[0041] The embodiment of the present invention provides a welding tray installation device, which can be installed for welding trays of different shapes and sizes and has high adaptability and flexibility.

[0042] See also Figures 1 to 9The welding plate installation device provided by the embodiment of the present invention includes a mounting plate 1, an adjustment component 2 and a placement component 3. Among them, the mounting plate 1 extends in the vertical direction, and two mounting plates 1 are provided, and the two mounting plates 1 are arranged at intervals along the first straight line direction; the adjustment component 2 is sandwiched between the two mounting plates 1, and a group of adjustment components 2 is provided corresponding to each mounting plate 1, and the two groups of adjustment components 2 are symmetrically arranged and connected to each other, and each group of adjustment components 2 includes a movable end 201 and a moving end 202, and the movable end 201 is movably connected to the mounting plate 1 and can move on the mounting plate 1 along the second straight line direction; the moving end 202 is movably connected to the mounting plate 1 and can move on the mounting plate 1 along the vertical direction; the placement component 3 is detachably arranged on the adjustment component 2, and the welding plate 200 is detachably connected to the placement component 3.

[0043] The welding plate installation device proposed by the present invention provides a stable support by setting a mounting plate 1, and two groups of adjustment components 2 are set to improve the stability of the connection of the placement component 3, thereby ensuring the stable connection of the welding plate 200. The movable end 201 and the mobile end 202 of each group of adjustment components 2 enable the welding plate 200 to be flexibly adjusted on the mounting plate 1, and the movable end 201 can move along the second straight line direction on the mounting plate 1, so that the position of the placement component 3 in the horizontal direction can be adjusted; the mobile end 202 can move along the vertical direction on the mounting plate 1, so that the position of the placement component 3 in the vertical direction can be adjusted. Through the coordinated cooperation of the movable end 201 and the mobile end 202, the position of the placement component 3 is adjusted, so that the placement component 3 can adapt to welding plates 200 of different sizes and shapes, and meet the diverse installation requirements in the distribution network handover box. The operator only needs to adjust the movable end 201 and the mobile end 202 of the adjustment component 2 to adapt to welding plates 200 of different specifications, without replacing the entire distribution network handover box, thereby improving the adaptability of the distribution network handover box, thereby saving installation time and labor.

[0044] See also Figure 4 and Figure 5Specifically, the adjustment assembly 2 includes a connecting rod 21 and a reinforcing rod 22, one end of the connecting rod 21 is hinged to one end of the reinforcing rod 22, the other end of the connecting rod 21 is a movable end 201, the other end of the reinforcing rod 22 is a movable end 202, and the connecting rod 21 and the reinforcing rod 22 are arranged at an angle. The adjustment assembly 2 is formed by hinged connection of the connecting rod 21 and the reinforcing rod 22, which has a simple structure and is easy to implement. At the same time, the position can be flexibly adjusted by relative rotation of the two to meet the installation requirements of welding trays 200 of different sizes. The movable end 201 of the connecting rod 21 can move along the second straight line direction on the mounting plate 1, and the movable end 202 of the reinforcing rod 22 can move along the vertical direction. The movable end 201 of the connecting rod 21 can be adjusted to adjust the position of the placement component 3 in the horizontal direction, and the movable end 202 of the reinforcing rod 22 can be adjusted to adjust the angle of the placement component 3 in the vertical direction, so that it can better adapt to various different welding trays 200, and further enhance the adaptability of the welding tray installation device to welding trays 200 of different sizes. Furthermore, the connecting rod 21 and the reinforcing rod 22 are arranged at an angle, which can not only ensure the flexibility of the adjustment component 2, but also make the connecting rod 21, the reinforcing rod 22 and the mounting plate 1 form a triangular structure. Through the stable geometric characteristics of the triangle, it can also provide a certain stability for the welding tray 200, ensuring the reliability of the welding tray installation device during installation and use.

[0045] More specifically, the axes of the two connecting rods 21 of the two groups of adjustment components 2 are coincident in the same horizontal plane, so that the entire adjustment component 2 can maintain good symmetry and stability in the horizontal direction, ensuring that there will be no deflection and other problems during installation and adjustment, which is conducive to more accurate adaptation of the welding plate 200. The two reinforcement rods 22 are arranged at a first angle and are hinged to each other. The size of the first angle can be changed according to actual needs to achieve fine adjustment of the positions of the two adjustment components 2, so that welding plates 200 of different sizes and shapes can be more closely fitted, thereby improving the compatibility and adaptability to various welding plates 200.

[0046] See also Figure 4 , Figure 7 and Figure 8In order to ensure that the adjustment assembly 2 does not interfere with the placement assembly 3 during movement, the placement assembly 3 includes an adapter plate 31. Each set of adjustment assemblies 2 is provided with an adapter plate 31. The reinforcement rod 22 is provided with a first bolt 221. The adapter plate 31 is provided with a first movable slot 311 extending along the second straight line direction. The first bolt 221 is slidably connected with the first movable slot 311. When the movable end 202 of the reinforcement rod 22 moves in the vertical direction to adjust the angle, the first bolt 221 of the adapter plate 31 can move relatively along the first movable slot 311, which can prevent the placement assembly 3 from getting stuck and interfering with the movement of the reinforcement rod 22, and improve the stability of the placement assembly 3. The first bolt 221 is threadedly connected with a first locking nut 222, and the first locking nut 222 can abut against the adapter plate 31. When the reinforcement rod 22 moves to a suitable position, the first locking nut 222 is screwed so that the first locking nut 222 abuts against the adapter plate 31, thereby limiting the relative movement of the first bolt 221 and the first movable through groove 311, so as to limit the position of the reinforcement rod 22, prevent the reinforcement rod 22 from being offset, and improve the stability of the adjustment assembly 2.

[0047] Specifically, a positioning head 223 is provided at the bottom of the first bolt 221, a positioning slot 224 is provided on the side wall of the positioning head 223, a positioning protrusion 225 is provided on the side wall of the reinforcement rod 22, and the positioning slot 224 is slidably connected to the positioning protrusion 225, thereby further improving the stability of the reinforcement rod 22 during movement.

[0048] More specifically, the movable end 202 of the reinforcing rod 22 can only adjust the angle of the placement assembly 3 in the vertical direction by moving in the vertical direction. In order to further improve the adaptability of the placement assembly 3 so that the placement assembly 3 can adjust its angle in the horizontal direction, a second bolt 211 is provided on the connecting rod 21, and a second movable through slot 312 extending in the first straight line direction is also provided on the adapter plate 31. The second bolt 211 is slidably connected with the second movable through slot 312, and a second locking nut 212 is threadedly connected to the second bolt 211, and the second locking nut 212 can abut against the adapter plate 31. Therefore, the operator drives the adapter plate 31 to move in the first straight line direction, so that the second movable through slot 312 and the second bolt 211 generate relative movement, so as to realize the angle adjustment process of the placement assembly 3 in the horizontal direction. When the adapter plate 31 moves to a suitable position, the second locking nut 212 is screwed so that the second locking nut 212 abuts against the adapter plate 31, thereby limiting the relative movement of the second bolt 211 and the second movable through groove 312, so as to limit the position of the rod of the adapter plate 31, prevent the adapter plate 31 from being offset, and improve the stability of the adjustment assembly 2.

[0049] In order to facilitate the installation of the welding tray 200 and the placement component 3, the placement component 3 also includes a clamping member 32. A clamping member 32 is provided for each group of adjustment components 2. The clamping member 32 and the adapter plate 31 are integrally formed to ensure the integrity and stability of the structure, and are also convenient for processing and manufacturing. The clamping member 32 is provided with a movable groove 321 extending along the second straight line direction. By plugging the movable groove 321, the welding tray 200 can be quickly inserted into the movable groove 321 to achieve the installation process with the placement component 3. The movable grooves 321 of the two clamping members 32 are arranged opposite to each other, and the two sides of the welding tray 200 can be respectively inserted into the movable grooves 321, which can well fix and limit the two sides of the welding tray 200, ensure the firmness and stability of the installation of the welding tray 200, and avoid shaking or displacement during use.

[0050] In other embodiments, the welding plate 200 and the placement component 3 can also be connected by magnetic attraction, snap connection, etc. The specific connection method is not limited here, and it only needs to ensure that the welding plate 200 can be detachably connected to the placement component 3.

[0051] Regarding the movement process of the movable end 201. The adjustment component 2 includes a guide slider 23, the movable end 201 is threadedly connected to the guide slider 23, a positioning block 11 is fixedly connected to the mounting plate 1, a guide groove 111 is provided on the positioning block 11, the guide groove 111 extends along the second straight line direction, and the guide slider 23 is slidably connected to the guide groove 111. The guide slider 23 is threadedly connected to the movable end 201, so that the movement of the movable end 201 can be precisely controlled and adjusted through rotation, and the position can be finely adjusted according to actual needs, thereby improving the precision and accuracy of the adjustment. At the same time, the guide slider 23 is slidably connected to the guide groove 111 extending along the second straight line direction on the positioning block 11, providing a stable guide for the movement of the movable end 201, ensuring that it moves smoothly along the specified second straight line direction, avoiding deviation or shaking, so as to better adapt to the installation requirements of different welding trays 200.

[0052] In addition, in the present embodiment, a threaded line is provided on the outer surface of the connecting rod 21 near the movable end 201, and a third locking nut 213 is threadedly connected to the connecting rod 21, and the third locking nut 213 can abut against the guide groove 111. When the guide slider 23 moves to a suitable position, the third locking nut 213 is screwed so that the third locking nut 213 abuts against the guide groove 111, thereby limiting the relative movement of the guide slider 23 and the guide groove 111, so as to limit the connecting rod 21, prevent the connecting rod 21 from being offset, and improve the stability of the adjustment component 2.

[0053] Regarding the movement process of the mobile terminal 202. A mounting flange 12 is formed on the mounting plate 1, and the mounting flange 12 extends along the first straight line direction. A plurality of positioning holes 121 are provided on the mounting flange 12, and the plurality of positioning holes 121 are arranged at intervals along the vertical direction. The mobile terminal 202 is selectively connected with the positioning holes 121, and the mobile terminal 202 and the positioning holes 121 are locked by the locking structure 24. The setting of the mounting flange 12 and the plurality of positioning holes 121 arranged at intervals along the vertical direction provide the mobile terminal 202 with a plurality of fixed position options, thereby enabling the mobile terminal 202 to be adjusted in multiple gears in the vertical direction, adapting to the different height requirements of welding trays 200 of different sizes, and improving the adaptability of the placement component 3. Secondly, the selective connection between the mobile end 202 and the positioning hole 121 and the locking through the locking structure 24 ensure that the mobile end 202 can be stably fixed after being adjusted to the appropriate position, thereby ensuring the reliability and safety of the adjustment component 2 and preventing the installation and use of the welding plate 200 from being affected by the looseness of the mobile end 202.

[0054] See also Fig. 9 Specifically, the locking structure 24 includes a U-shaped plate 241, a shell 242, an insert block 243, a limit block 244 and a locking bolt 245. The movable end 202 is hinged to the U-shaped plate 241, and the U-shaped plate 241 is slidably connected to the mounting protrusion 12. One side of the U-shaped plate 241 is fixedly connected to the shell 242, and an insert block 243 is arranged inside the shell 242. A first threaded hole 2431 is penetrated on the insert block 243. The other side of the U-shaped plate 241 is fixedly connected to the limit block 244, and a second threaded hole 2441 is penetrated on the limit block 244. The first threaded hole 2431 and the second threaded hole 2441 are coaxially arranged, and the locking bolt 245 can be sequentially penetrated through the first threaded hole 2431, the positioning hole 121 and the second threaded hole 2441. When in use, the mounting flange 12 can be plugged into the U-shaped plate 241 and slidably connected with the U-shaped plate 241, thereby providing a guiding effect for the movement process of the mobile end 202. When the mobile end 202 moves to a suitable position, ensure that the first threaded hole 2431 and the second threaded hole 2441 are aligned with the positioning hole 121 on the mounting flange 12. Thereafter, the locking bolt 245 can be sequentially passed through the first threaded hole 2431, the positioning hole 121 and the second threaded hole 2441, thereby completing the positioning process of the U-shaped plate 241, preventing the mobile end 202 from loosening, deflecting, etc., and having higher stability.

[0055] In other embodiments, the locking structure 24 may be a locking pin, a locking buckle, etc., which are sequentially passed through the mobile terminal 202 and the positioning hole 121 to achieve the positioning process of the mobile terminal 202, which will not be elaborated here.

[0056] More specifically, the end of the housing 242 is fixedly connected with a round rod 246, and a spring 247 is sleeved on the round rod 246. A limiting protrusion 2451 is provided at the end of the locking bolt 245, and one end of the spring 247 abuts against the housing 242, and the other end of the spring 247 abuts against the limiting protrusion 2451. The round rod 246 and the spring 247 sleeved thereon form an elastic buffer mechanism. When the locking operation is performed, the spring 247 can play a certain buffering role, reduce the rigid collision between the locking bolt 245 and other components, reduce the risk of wear and damage, and increase the service life of the components. Secondly, the presence of the spring 247 enables the locking bolt 245 to better maintain a tightened state during the locking process. The elastic force of the spring 247 will continue to apply pressure to ensure that the locking bolt 245 will not loosen easily, further enhancing the reliability of the fixed position of the mobile end 202.
