[0029] Below, the present application is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] like Figure 1-5 As shown, the semi-solid sealed vacuum bubble installation device includes a clamping part 1 and an operating part 2. The clamping part 1 is used to clamp the shell 31 of the vacuum bubble, and the operating part 2 is used to tighten the shell 31 of the vacuum bubble and the soft connection 32 of the vacuum bubble and the pull rod 33 of the vacuum bubble.

[0031] The clamping portion 1 includes a base 11, a positioning plate 12 disposed on top of the base 11, and two positioning blocks 13. The positioning plate 12 is disposed at one end of the top of the base 11 and has a U-shaped bayonet 120 disposed on top of the positioning plate 12. The pull rod 33 can be adapted to be inserted into the bayonet 120. The two positioning blocks 13 are symmetrically disposed on either side of the bayonet 120. In other words, the two positioning blocks 13 and the positioning plate 12 are arranged in a herringbone shape. In this way, the positioning blocks 13 and the positioning plate 12 can reliably position the housing 31. Furthermore, a limiting groove 111 is provided on the top of the base 11, which extends along the length direction of the base 11 and is centrally arranged. In this way, when the shell 31 is placed horizontally on the base 11, the bottom of the shell 31 can fall into the limiting groove 111. At the same time, the notch of the limiting groove 111 is trumpet-shaped. In this way, the limiting groove 111 can adapt to shells 31 of different sizes, thereby reliably positioning and limiting the shell 31 together with the positioning block 13 and the positioning plate 12, ensuring that the shell 31 cannot easily rotate or move on the base 11.

[0032] A pair of threaded rods 14 are provided at the top of the base 11, and a through-hole 131 is provided on each of the two positioning blocks 13. The through-hole 131 extends through the positioning block 13 along its height, so that the pair of threaded rods 14 can be inserted into the two through-holes 131 in a one-to-one correspondence. A locking nut 141 is screwed onto each threaded rod 14. Once the positioning block 13 is in place, the locking nut 141 can be screwed downward so that it presses against the top of the positioning block 13. Since the threaded rods 14 are fixedly connected to the base 11, the positioning block 13 is securely fixed under the locking action of the locking nut 141. By selecting a positioning block 13 of an appropriate size, the distance between the two positioning blocks 13 can be adjusted. Alternatively, a plurality of through-holes 131 can be provided on the positioning block 13, and the distance between the two positioning blocks 13 can be adjusted by inserting the threaded rod 14 into different through-holes 131. In this way, the two positioning blocks 13 can be close to or directly fitted with the shell 31, thereby effectively improving the accuracy and reliability of the positioning and limiting of the shell 31.

[0033] A movable plate 142 is also sleeved on each threaded rod 14. The movable plate 142 has no connection with the threaded rod 14, that is, the movable plate 142 can move up and down or rotate circumferentially on the threaded rod 14. At the same time, an adjusting nut 144 is also screwed on each threaded rod 14. The adjusting nut 144 is located above the movable plate 142. By rotating the adjusting nut 144, the upper limit height of the movable plate 142 on the threaded rod 14 can be adjusted. The cam 143 is then rotated downwardly to allow the bottom of the housing 31 to fall into the retaining groove 111, and then the adjusting nut 144 is rotated downwardly to allow the adjusting nut 144 to approach the freely falling movable plate 142 and to press and push the movable plate 142 downwardly. In this way, the elastic band 143 will gradually approach and fit the top of the housing 31. When the movable plate 142 continues to move downward, the elastic band 143 will be stretched and elastically deformed. In this way, under the elastic force of the elastic band 143, the housing 31 is reliably fixed to the top of the base 11, thereby maximizing the fixing effect of the housing 31 and ensuring that the housing 31 will not move during the subsequent assembly process, thereby improving the assembly accuracy.

[0034] A pair of sidewalls along the length of the retaining groove 111 are each provided with a cushioning pad 112. One end of the cushioning pad 112 is located at the top of the base 11, and the other end of the cushioning pad 112 extends along the inner wall of the retaining groove 111 toward the bottom of the retaining groove 111. A plurality of columnar airbags 113 are spaced apart on the top of the cushioning pad 112. The airbags 113 extend along the length of the cushioning pad 112 and are spaced apart along the width of the cushioning pad 112. The airbags 113 on the pair of cushioning pads 112 are used to clamp the housing 31. The arrangement of the cushioning pads 112 and the airbags 113 ensures that when the elastic band 143 is tightened against the housing 31, the housing 31 will not be squeezed against the notch of the retaining groove 111, causing deformation or damage, thereby protecting the housing 31. Furthermore, under the clamping effect of the airbags 113 and the elastic force of the elastic band 143 , the difficulty of the housing 31 rotating is increased, thereby improving the fixing effect of the housing 31 on the base 11 .

[0035] The operating part 2 includes a chuck 21 and a torque wrench 22. A receiving groove 211 is provided on the side of the chuck 21 facing the shell 31, and a plurality of through grooves 212 are provided on the outer wall of the chuck 21. The plurality of through grooves 212 are arranged at equal intervals along the circumferential direction of the outer wall of the chuck 21. The through grooves 212 are opened from the end of one side of the chuck 21 facing the shell 31 and extend toward the end of the side of the chuck 21 facing away from the shell 31 (but will not extend to the end of the side of the chuck 21 facing away from the shell 31, that is, the through grooves 212 will not penetrate the chuck 21). The plurality of through grooves 212 are all connected with the receiving groove 211. A sleeve rod 213 is provided on the side of the chuck 21 facing away from the shell 31. The sleeve rod 213 is hexagonal and is arranged at the center of the end of the chuck 21. In this way, the torque wrench 22 can be quickly sleeved on the sleeve rod 213 and the sleeve rod 213 can be rotated.

[0036] After the housing 31 is placed and fixed on the base 11, the flexible connector 32 can be sleeved on the outside of the pull rod 33, and then one end of the pull rod 33 can be inserted into the bayonet 120 and aligned with the installation space on the housing 31. At this time, one end of the pull rod 33 is located on one side of the positioning plate 12, and the other end of the pull rod 33 is located on the other side of the positioning plate 12. Then, the receiving groove 211 on the clamping head 21 is aligned with the other end of the pull rod 33. Since the other end of the pull rod 33 is provided with a limit rod 330, and the limit rod 330 extends along the radial direction of the pull rod 33, when the clamping head 21 is inserted into the pull rod 33, the limit rod 330 will slide into any corresponding through groove 212. There can be one or more limit rods 330. At the same time, when there are multiple limit rods 330, the arrangement spacing of the limit rods 330 is the same as the arrangement spacing of the through grooves 212, ensuring that each limit rod 330 can slide into the corresponding through groove 212. The limiting effect on the clamping head 21 is achieved by cooperating with the limiting rod 330 and the through groove 212. That is, under the interference of the limiting rod 330, when the clamping head 21 is rotated by the torque wrench 22, the pull rod 33 can rotate synchronously with the clamping head 21, and then the pull rod 33 can be quickly and conveniently screwed into the shell 31 without causing the pull rod 33 to be screwed in too much and cause slippage or even damage. While ensuring precise assembly, the overall assembly efficiency is effectively improved.

[0037] The above-mentioned embodiments are only preferred embodiments of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and replacements made by technicians in this field based on the present application shall fall within the scope of protection required by the present application.
