[0026] The present utility model provides an anti-breakable internal threaded tube as shown in Figure 1 and includes a device body 1, and further includes:

[0027] A protection mechanism 2, which is arranged on the outer side of the device body 1 and is used for protecting and strengthening the outer side of the device body 1.

[0028] In order to make the internal structure of the internal threaded tube more firm and avoid breakage, as shown in Figure 2 and Figure 3 the device body 1 includes an inner fixing tube 101. A thread groove 102 is opened on the inner side of the inner fixing tube 101. A reinforcing net 103 is sleeved on the outer side of the inner fixing tube 101. An outer fixing tube 104 is sleeved on the outer side of the reinforcing net 103. Six reinforcing ribs 105 are fixedly installed on the outer wall of the outer fixing tube 104 at equal intervals in a circular shape. The reinforcing net 103 can strengthen the internal structure of the internal threaded tube, and at the same time, the reinforcing ribs 105 can strengthen the outer wall of the internal threaded tube.

[0029] In order to conveniently protect the outer wall of the internal threaded tube, as shown in Figure 2 and Figure 4As shown in the figure, the protection mechanism 2 includes a first protection plate 201. A second protection plate 202 is rotatably installed at the bottom of the first protection plate 201. The first protection plate 201 and the second protection plate 202 are movably sleeved on the outer side of the outer fixed tube 104. A plurality of clamping grooves 203 that are movably connected to the outer wall of the reinforcing rib 105 are provided on the inner sides of the first protection plate 201 and the second protection plate 202. Connection bolts 206 are provided between the inner walls at both ends of the top of the first protection plate 201 and the second protection plate 202. The outer wall of the internal thread tube can be protected by the first protection plate 201 and the second protection plate 202, and the outer wall of the internal thread tube can be prevented from being damaged.

[0030] To make the first protection plate 201 and the second protection plate 202 closely connected, as Figure 2 and Figure 4 shown, mounting holes 204 are provided on the inner walls at both ends of the top of the first protection plate 201. The inner walls of the two mounting holes 204 are respectively threadedly connected to the outer walls of one side of the two connection bolts 206. Fixing holes 205 are provided on the inner walls at both ends of the top of the second protection plate 202. The inner walls of the two fixing holes 205 are respectively threadedly connected to the outer walls of the side of the two connection bolts 206 away from the mounting holes 204. The connection bolts 206 penetrate through the inner walls of the mounting holes 204 and are threadedly connected to the inner walls of the adjacent fixing holes 205, so that the first protection plate 201 and the second protection plate 202 can be closely connected, and further the first protection plate 201 and the second protection plate 202 can stably protect the internal thread tube.

[0031] To make the internal structure of the internal thread tube more stable, as Figure 2 and Figure 3 shown, the outer diameter dimension of the inner fixed tube 101 is the same as the inner diameter dimension of the reinforcing mesh 103, and the outer diameter dimension of the reinforcing mesh 103 is the same as the inner diameter dimension of the outer fixed tube 104. The reinforcing mesh 103 is arranged between the inner fixed tube 101 and the outer fixed tube 104, and the internal structure of the internal thread tube can be reinforced.

[0032] To make the first protection plate 201 and the second protection plate 202 stably protect the outer wall of the internal thread tube, as Figures 2 - 4 shown, the inner diameter dimensions of the first protection plate 201 and the second protection plate 202 are the same as the outer diameter dimension of the outer fixed tube 104. The first protection plate 201 and the second protection plate 202 are both made of soft rubber material components. The left vertical cross-sections of the reinforcing rib 105 and the clamping groove 203 are both rectangular structures. The area dimension of the left vertical cross-section of the reinforcing rib 105 is the same as the area dimension of the left vertical cross-section of the clamping groove 203. The clamping groove 203 is sleeved on the outer side of the adjacent reinforcing rib 105, so that the first protection plate 201 and the second protection plate 202 can be stably sleeved on the outer side of the outer fixed tube 104, and the first protection plate 201 and the second protection plate 202 can stably protect the internal thread tube.

[0033] The specific implementation method is as follows: When manufacturing and processing the internal-thread pipe, a thread groove 102 is provided on the inner wall of the inner fixing pipe 101. At the same time, a reinforcing net 103 is sleeved on the outer side of the inner fixing pipe 101. Then, an outer fixing pipe 104 is sleeved on the outer side of the reinforcing net 103. The inner-thread pipe main body is jointly constituted by the inner fixing pipe 101, the reinforcing net 103, and the outer fixing pipe 104. Then, a plurality of reinforcing ribs 105 are integrally formed on the outer side of the outer fixing pipe 104. The setting of the reinforcing net 103 makes the internal structure of the inner-thread pipe more stable. At the same time, the reinforcing ribs 105 can reinforce the outer wall of the inner-thread pipe, which can prevent the inner-thread pipe from breaking. At the same time, the first protection plate 201 and the second protection plate 202 are sleeved on the outer side of the outer fixing pipe 104, so that the clamping grooves 203 on the inner walls of the first protection plate 201 and the second protection plate 202 can be sleeved on the outer sides of the plurality of reinforcing ribs 105. Then, the connecting bolt 206 is passed through the inner wall of the mounting hole 204 and is threadedly connected with the inner wall of the adjacent fixing hole 205, so that the first protection plate 201 and the second protection plate 202 are tightly connected. Furthermore, the protection mechanism 2 can be stably sleeved on the outer side of the inner-thread pipe, and thus the outer wall of the inner-thread pipe can be stably protected. Furthermore, the situation that the inner-thread pipe breaks can be avoided, and the service life of the inner-thread pipe can be prolonged. This specific implementation method specifically solves the problems in the prior art that the inner-thread pipe is easily broken during use and installation and has a short service life.

[0034] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways.
