Description

Dental plug structure

The present invention relates to a dental mouth structure, and more particularly to a dental plug structure that facilitates sealing of a tooth plug.

In general building houses, water and electric piping will be buried in the pre-formed wall (first wall) or cement column. The water outlet pipe is connected to the faucet of the water outlet, due to grouting, tiling, painting, etc. Cement, gravel or other debris may enter the water outlet pipe. Therefore, in order to prevent the water outlet pipe from being blocked, most of them will be sealed with a tooth plug at the outlet end of the water outlet pipe 2, or In order to change the position of the faucet, it may be changed or not used. Therefore, the plug will be locked at the outlet end of the outlet pipe of the faucet before installation, and the general plug will have a polygonal clip toward the outer end. a holding portion, and the inner end portion has a threaded portion, the threaded portion is for locking in the outlet end of the water outlet pipe, so that the outlet end of the water outlet pipe is sealed, and generally after the procedure is completed After the grouting, tiling, and painting to form the second wall surface, the tooth plug portion is buried in the wall surface, but in order to install the faucet, the tooth plug must be taken out of the wall; But the actual situation is that the tooth plug and coagulation After the materials are combined, it is difficult to pull out directly, so it is necessary to knock out a part of the second wall surface to expose the contact portion of the tooth plug with the outlet end of the water outlet pipe, then rotate the tooth plug and insert the tooth plug After being pulled out, the faucet can be re-locked; However, in the above method, since one part of the wall must be knocked off, in order to facilitate the removal of the tooth plug, a hole larger than the diameter of the tooth plug can be hammered out by the tool to facilitate the removal of the tooth plug. However, the random knocking will make the second wall surface that has been grouted, affixed with tiles, and painted a very ugly hole. Therefore, when installing the faucet, there must be a large stop to block the faucet. a hole outside the junction with the outlet end of the water outlet pipe; and since the tooth plug is a polygonal clamping portion toward the outer end, if the tooth plug is to be rotated, a tool such as a pliers or a wrench must be used. It is possible to rotate the tooth plug, so if the constructor forgets to carry such a tool, the whole project will be stopped, so the current tooth plug and the method of its use have great shortcomings to be improved.

Referring to the Chinese Patent No. M441765, it is known that a pipe plug structure includes a plug body and a sleeve, the plug body having a cylindrical body and a threaded column of a smaller outer diameter, the inside of the cylinder body having an opening toward an end surface. a polygonal groove, the cylinder body forming a closed end and an open end, the end edge of the open end of the cylindrical body having a convex portion protruding outward and being annular, the threaded column being closed in the cylindrical body The end surface of the end is screwed into a water outlet of a water pipe, and the sleeve has a set of holes penetrating through the two ends for the cylindrical body to be rotatably disposed therein; the structure is easy to disassemble by the above structure; However, the above-mentioned patent case M441765 (hereinafter referred to as citation 1) has the following disadvantages, and is explained as follows: (1) Reference is made on page 6 of the cited document 1 and, after the plug body 20 is detached, the sleeve 30 can be protruded from the wall surface. The part of the cutting is flattened to be flush with the wall. Then the faucet 42 is screwed into the water outlet 41 to complete the installation of the faucet 42. Thus, the reference 1 only mentions that the ring sleeve will be cut. Cut and flatten, but does not mention the technique of extraction and separation; (2) Citation 1 needs to cut the ring casing Cut and flatten, but the cutting and leveling requires tools, and in the process of cutting and flattening, it is impossible to avoid causing the surface of the tile 43 due to the complete cutting. (3) Since the reference 1 is that the sleeve 30 is sleeved on the plug body 20 from the threaded post 22, as can be seen from the sixth figure of the reference 1, the threaded post 22 is locked to the water pipe 40. There are 41 outlets, but the method of doing this is disadvantageous. If the thread at the outlet 41 is too short, the following will occur: (a) after the plug is locked at the water outlet of the water pipe, if The threaded post 22 is too long, and the thread at the water outlet 41 is too short, so that the sleeve will sway back and forth, so the sleeve will not fit the opening at the water outlet of the water pipe; (b) The problem is that since the end of the plug body 20 of the cited 1 has a convex portion 26, the sleeve 30 cannot be inserted from the rear end of the plug body 20, and the gap between the sleeve and the water outlet of the water pipe will be very high. It may cause the liquid oozing from the water outlet of the water pipe to penetrate into the powder layer 44. This is the most serious shortcoming of Citation 1, which is also the reason why this product has never been used and appeared in the industry; c) The reference 1 needs to be removed after the plug 20 is reversed, and the sleeve 30 can be replaced, and the length of the sleeve 30 of the cited 1 is Must be between the threaded post 22 and the raised portion 26, but if the sleeve 30 needs to be longer (before the length between the threaded post 22 and the raised portion 26), it can be brought up to the water outlet of the water pipe, Citation 1 will not solve the above problem; (d) and the technique of Citation 1 is applied to different pipes, and the same problem as above will occur.

Referring to the Republic of China Patent No. M436761, it is known that a water pipe group includes: a main pipe, one end of which forms a set of joints, the periphery of the joint portion extends radially outward to a wall; a drainage pipe is closely attached Abutting the wall of the assembly and communicating with the main pipe, the drainage pipe has a drainage space; and a set of nozzles are received in the drainage space of the drainage pipe and are engaged with the assembly And connecting the main line, and forming a drainage channel between the outer wall of the set of tubes and the inner wall of the draft tube; However, the above-mentioned patent case M436761 (hereinafter referred to as citation 2) has the following disadvantages, which are explained as follows: (1) From page 7 to line 7 to 7 of the citation 2, it is mentioned that "the drainage tube 2 is specially made of a material such as rubber to Increase the flexibility and the convenience of cutting." It can be seen that Citation 2 only mentions the ability to cut, but does not disclose the technique of extraction and separation; (2) from the seventh page of Citation 2, "Preferably, the abutment The portion 22 extends radially from an open end edge of the draft tube 2, and a shoulder 222 protrudes from the outside of the tube wall of the draft tube 2, thereby increasing the joint stability of the drain tube 2 through the shoulder edge 222. It can be seen that the shoulder 222 is for the purpose of making the drainage tube 2 more stable, and the presence of the shoulder 222 also makes the drainage tube 2 unable to be pulled out; (3) the content of the page 9 of the reference 2 "the convex ring 23, the structural strength of the drainage tube 2 can be simultaneously increased to avoid deformation of the drainage tube 2. It can be seen that the convex ring 23 is a structure for making the drainage tube 2 more stable, and the presence of the convex ring 23 also makes the The drainage tube 2 cannot be pulled out; (4) the content of the seventh page of the citation 2 "Please refer to Figure 4, when the creation of the water pipe group is actually When the device is installed and installed on a cement wall W, a pressing member 4 can be selected, and the main pipe 1 and the drainage pipe 2 are forced by the pressing member 4, wherein the pressing member 4 can be selected. It is a general water pipe plug to force the drainage pipe 2 and the main pipe 1 to increase the stability of the assembly, and at the same time to block the flow of water from the main pipe 1 as the main principle." It can be seen that the drainage of the citation 2 Tube 2 is used to avoid leakage, so the drainage tube 2 of the cited 1 is impossible to take out; (5) As mentioned in the reference 2, the drainage tube 2 is made of rubber material, but it is well known that rubber There are pores on the surface, so when the rubber is in contact with the cement, part of the cement will penetrate into the capillary pores of the rubber surface, so that the rubber and the cement can be more tightly engaged, so the drainage tube 2 is pulled out from the outer layer cement S. Very difficult, but the reference 2 does not really need to pull the drainage tube 2 out of the outer layer of cement S, so the material such as rubber is used to make the drainage tube 2, Only the drainage tube 2 can be more closely engaged with the outer layer cement S.

Therefore, if the structure of the tooth plug can be improved, the constructor can carry out the construction without special tools, and when the ring sleeve is placed, it can slide along the outer surface of the tooth plug body and can be stuck on the tooth. On the surface of the plug body, and in the process of removing the tooth plug, it is not necessary to strike the wall surface, so that the grouted, affixed tile, and the painted wall form a complete and smooth hole, and the hole does not Too large, so the faucet does not need to have a large stop structure, so the invention should be an optimal solution.
