Description

Technical Field

[0001] This application relates to the field of medical devices, and more particularly to a threaded tube that prevents loosening. Background Technology

[0002] Threaded tubes are widely used storage containers, especially in the fields of biochemistry and molecular biology, where they are used for the preservation and transportation of solutions.

[0003] A conventional threaded tube consists of a tube body and a cap, which are connected by threads. This type of connection can slip due to various external forces, leading to loosening of the connection between the cap and the tube body, or the cap falling off the tube body, causing leakage of the solution inside the tube.

[0004] Therefore, how to design a threaded pipe that prevents the cap from detaching from the pipe body has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This application provides a threaded pipe that prevents loosening, thereby at least solving the above-mentioned technical problems existing in the prior art.

[0006] According to a first aspect of this application, a threaded tube resistant to loosening is provided, comprising a tube body;

[0007] The pipe body is threaded;

[0008] The snap and slot are provided in several parts and are located on the thread;

[0009] The pipe cap is threaded to the pipe body.

[0010] The buckle is located on the side wall of the pipe cap, and the buckle and teeth on the buckle are engaged in the buckle and groove.

[0011] In one embodiment, the buckle and groove are serrated, and the buckle teeth are adapted to the buckle and groove.

[0012] In one embodiment, the cross-section of the buckle and groove is a right triangle, with one side wall of the buckle and groove being a right-angled side and the other side wall being a hypotenuse, and the buckle and groove are adapted to each other.

[0013] In one embodiment, the side wall of the pipe cap is provided with an installation port, and the snap fastener is installed in the installation port.

[0014] In one embodiment, the side wall of the buckle is fixedly provided with a connecting rib, which is fixedly connected to the pipe cover.

[0015] In one embodiment, the side wall of the pipe cap is provided with an installation opening, and the buckle also includes a first layer and a second layer; the buckle and teeth, the second layer and the first layer are arranged sequentially from the inside to the outside along the radial direction of the pipe cap, the buckle and teeth, the second layer and the first layer are integrally formed, the second layer is located inside the installation opening, the bottom wall and the top wall of the second layer abut against the bottom wall and the top wall of the installation opening respectively, and the first layer is located outside the installation opening.

[0016] In one embodiment, the sidewall of the second layer and the sidewall of the mounting port are provided with a gap for the buckle to rotate circumferentially around the axis of the pipe cover.

[0017] In one embodiment, a limiting ring is fixedly provided on the outer wall of the pipe body, and an anti-detachment ring is also included. The anti-detachment ring is fixedly connected to the first layer through a connecting strip. The diameter of the anti-detachment ring is larger than the outer diameter of the pipe body and smaller than the outer diameter of the limiting ring.

[0038] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Example 1:

[0040] This embodiment refers to Figures 1 to 4 .

[0041] Specifically, such as Figure 1 and Figure 2 As shown, it includes a pipe body 1, wherein the outer wall of the top of the pipe body 1 is provided with a thread 10, and also includes a pipe cap 2, wherein the pipe cap 2 is threadedly connected to the pipe body 1 through the thread 10.

[0042] like Figure 3As shown, it also includes several buckles and grooves 101, wherein the several buckles and grooves 101 are distributed on the thread 10 along the helical direction of the thread 10, and a buckle 3 is installed on the side wall of the pipe cover 2, wherein the buckle 3 is provided with buckles and teeth 31 for inserting into the buckles and grooves 101.

[0043] With the above settings, when the pipe cover 2 is threadedly connected to the pipe body 1 via the thread 10, the buckle and teeth 31 installed on the pipe cover 2 are inserted into the buckle and groove 101. At this time, the buckle and groove 101 can restrict the pipe cover 2 from rotating relative to the pipe body 1 through the buckle and teeth 31, thereby solving the problem of the pipe cover 2 becoming loose from the pipe body 1, or the pipe cover 2 falling off the pipe body 1.

[0044] Specifically, in this embodiment, such as Figure 3 As shown, the buckle and groove 101 adopts a sawtooth shape, and the buckle and tooth 31 is adapted to the buckle and groove 101. Furthermore, the cross-section of the buckle and groove 101 is a right triangle, with one side wall of the buckle and groove 101 being a right-angled side and the other side wall being the hypotenuse of the right triangle.

[0045] In this embodiment, when the tube cap 2 is installed on the tube body 1 clockwise, as the tube cap 2 rotates, the inclined edge on the buckle and tooth 31 fits against the inclined surface of the buckle and groove 101, the buckle and tooth 31 jumps, and the tube cap 2 gradually moves downward along the axial direction of the tube body 1, thereby installing the tube cap 2 on the tube body 1.

[0046] Specifically, such as Figure 4 As shown, the buckle 3 is provided with a connecting rib 32, which is fixedly connected to the pipe cover 2.

[0047] When the cap 2 tends to rotate counterclockwise, the right-angled side of the buckle and groove 101 abuts against the right-angled side of the buckle and tooth 31, thereby restricting the cap 2 from rotating counterclockwise and thus solving the problem of the cap 2 becoming loose from the tube body 1.

[0048] If it is necessary to open the cap 2, then the force of turning the cap 2 counterclockwise needs to be increased to break the connecting rib 32, remove the buckle 3 from the cap 2, and then the cap 2 can be removed from the tube body 1 to pour out the solution inside the tube body 1.

[0049] Specifically, in order to achieve the installation of the clip 3, in this embodiment, as follows: Figure 4 As shown, the side wall of the pipe cover 2 is provided with an installation port 21, wherein the buckle 3 is inserted into the installation port 21 and is fixedly connected to the inner wall of the installation port 21 by the connecting rib 32.

[0050] This technical solution allows for clear observation of whether tube 1 has been opened.

[0051] Example 2:

[0052] This embodiment refers to Figure 5, Figure 6 and Figure 9 .

[0053] In this embodiment, the pipe body 1 is provided with a thread 10, and the thread 10 is provided with a buckle and groove 101, including a pipe cover 2. The pipe cover 2 is threadedly connected to the pipe body 1 through the thread 10. The side wall of the pipe cover 2 is provided with an installation port 21, and a buckle 3 is installed in the installation port 21. The buckle 3 is provided with a buckle and teeth 31 for inserting into the buckle and groove 101. It is worth noting that the buckle 3 and the pipe cover 2 are detachably connected.

[0054] During use, first install the pipe cap 2 onto the pipe body 1 using the thread 10. The buckle and groove 101 on the thread 10 can be seen from the installation port 21 of the pipe cap 2. Then, insert the buckle 3 into the installation port 21, so that the buckle and teeth 31 on the buckle 3 are inserted into the buckle and groove 101. The mutual adaptation of the buckle and groove 101 and the buckle and teeth 31 can restrict the relative movement of the pipe cap 2 and the pipe body 1, thus solving the problem of the pipe cap 2 becoming loose.

[0055] Specifically, such as Figure 5 and Figure 9 As shown, the buckle and groove 101 can be selected as one of serrated, rectangular or rectangular, and the buckle and teeth 31 are adapted to the shape of the buckle and groove 101.

[0056] When the pipe cap 2 is installed on the pipe body 1, if the buckle 3 is inserted into the installation port 21, the buckle 3 cannot rotate circumferentially around the axis of the pipe cap 2. This will cause the buckle and teeth 31 to be misaligned with the buckle and groove 101, resulting in the buckle and teeth 31 being unable to be inserted into the buckle and groove 101.

[0057] Therefore, in this embodiment, as Figure 6 As shown, the buckle 3 also includes a first layer 34 and a second layer 33. The buckle and teeth 31, the second layer 33 and the first layer 34 are arranged sequentially from the inside to the outside along the radial direction of the tube cover 2. The buckle and teeth 31, the second layer 33 and the first layer 34 are integrally formed. The second layer 33 is inserted into the mounting port 21 and the first layer 34 remains on the outside of the mounting port 21.

[0058] Here, the direction along the axis of the tube body 1 is defined, with the direction closer to the bottom of the tube body 1 as the bottom and the opening at the end of the tube body 1 as the top. The other two side walls of the mounting port 21 are defined as the left wall and the right wall, respectively. After the second layer 33 is installed inside the mounting port 21, the upper and lower walls of the second layer 33 abut against the top and bottom walls of the mounting port 21, respectively, to restrict the buckle 3 from moving upward along the axis of the tube body 1. A gap is left between the left and right walls of the second layer 33 and the left and right walls of the mounting port 21 to allow the buckle 3 to rotate circumferentially along the tube cover 2.

[0059] The advantage of this design is that when the second layer 33 is inserted into the mounting port 21, the position of the buckle 3 can be adjusted by the first layer 34, so that the buckle and tooth 31 can be inserted into the buckle and groove 101.

[0060] The first layer 34 is located outside the mounting port 21, and the clip 3 can be removed from the tube cover 2 through the first layer 34.

[0061] Example 3:

[0062] This embodiment refers to Figures 7 to 9 This embodiment is an improvement on embodiment two, mainly to prevent the loss of the clip 3.

[0063] like Figure 7 As shown, a limiting ring 11 is provided on the outer wall of the pipe body 1, and an anti-detachment ring 4 is also included. The anti-detachment ring 4 is fixedly connected to the first layer 34 of the buckle 3 by a connecting strip 41. The diameter of the anti-detachment ring 4 is larger than the outer diameter of the pipe body 1, and the inner diameter of the anti-detachment ring 4 is smaller than the outer diameter of the limiting ring 11. When the anti-detachment ring 4 is installed, as shown... Figure 8 As shown, first, the anti-detachment ring 4 is fitted onto the tube body 1, so that the bottom wall of the anti-detachment ring 4 abuts against the top wall of the limiting stop ring 11. Then, the tube cap 2 is screwed onto the tube body 1 to install the tube cap 2. At this time, the bottom wall of the tube cap 2 abuts against the top wall of the anti-detachment ring 4 to prevent the anti-detachment ring 4 from being removed from the top of the tube body 1, thus fixing the anti-detachment ring 4. Then, the buckle 3 is inserted into the installation port 21, so that the buckle and tooth 31 are inserted into the buckle and groove 101. At this time, the buckle 3 is installed on the anti-detachment ring 4, solving the problem of the buckle 3 being lost.
