Detailed Embodiment
[0025] As Figure 1 shown, this embodiment includes a pipe body 1 and a pipe joint 2. One end of the pipe joint 2 is inserted into one end of the pipe body 1. The side wall of the pipe body 1 is provided with a strip-shaped installation slot hole 11, and the side wall of the pipe joint 2 is provided with a strip-shaped locking slot hole 21 corresponding to the shape of the installation slot hole 11. When the pipe joint 2 is inserted into the pipe body 1, the positions of the installation slot hole 11 and the locking slot hole 21 are corresponding.
[0026] This embodiment further includes a locking block 3. One end of the locking block 3 is hinged to one end of the mounting slot hole 11. The length of the locking block 3 should not exceed the length of the mounting slot hole 11. The locking block 3 can rotate around the hinge axis and sink into the mounting slot hole 11. A lock button is provided at the other end of the locking block 3. When the locking block 3 sinks into the mounting slot hole 11, rotating the lock button can fix the locking block 3 on the mounting slot hole 11.
[0027] This embodiment provides a specific structure of the lock button. As shown in Figure 2 、 3 、4, 5, a lock hole 35 is provided at the other end of the locking block 3. The lock button includes a lock pin 4 and a snap ring. The lock pin 4 is T-shaped. Two symmetrically arranged notches 41 are provided at the edge of the T-shaped end face of the lock pin 4. A strip-shaped card slot 42 is provided at the symmetry line position of the two notches 41. After the lock pin 4 is inserted into the lock hole 35, it is fixed with a snap ring. The lock pin 4 can rotate freely in the lock hole 35. At the same time, a retaining convex 111 is provided at the edge of the other end of the mounting slot hole 11, and the retaining convex 111 corresponds to the notch 41 and the card slot 42. When the locking block 3 sinks into the mounting slot hole 11, the retaining convex 111 can pass through the notch 41 without affecting the locking block 3 sinking into the mounting slot hole 11. Then, rotate the lock pin 4 so that the retaining convex 111 is stuck into the card slot 42 to lock the locking block 3.
[0028] A strip-shaped locking portion 31 is also provided at the position of the locking block 3 close to the hinge axis. After the locking block 3 sinks into the mounting slot hole 11, the locking portion 31 is stuck into the locking slot hole 21 to prevent the pipe joint 2 from detaching from the pipe body 1, achieving the purpose of locking the pipe joint 2.
[0029] This device has two usage states, namely the locking state of locking the pipe body 1 and the pipe joint 2, and the releasing state of releasing the pipe body 1 and the pipe joint 2. In the locking state, the locking portion 31 is inserted into the locking slot hole 21 to lock the pipe joint 2 on the pipe body 1. In the releasing state, the locking portion 31 disengages from the locking slot hole 21, and the pipe joint 2 can be pulled out from the pipe body 1. The locking block 3 rotates around the hinge axis to realize the conversion between the locking state and the releasing state.
[0030] The present invention uses the locking block 3 to fix the pipe joint 2 on the pipe body 1, and the locking block 3 applies an axial force to the pipe joint 2, which makes the force on the locked pipe joint 2 reasonable, enhances the firmness of the interface, and is not prone to breakage.
[0031] The operation of the present invention is also very simple. Just move your finger to easily disassemble and assemble the pipe body 1 and the pipe joint 2. In the present invention, rotating the locking portion 31 to convert it from a vertical state to a horizontal state realizes tightening. According to the lever principle, this operation method is very labor-saving. Even if the pipe body 1 and the pipe joint 2 are very thick pipes, operating with one hand will not be too strenuous.
[0032] Preferably, in this embodiment, a through hole 311 is provided in the direction parallel to the axis of the pipe body 1 in the locking portion 31. In addition, a top bead 32, a top spring 33, and a top pin 34 are also provided. The top bead 32, the top spring 33, and the top pin 34 are sequentially arranged in the through hole 311. A retaining ring 312 is provided at one end of the top pin 34, and the retaining ring 312 is used to prevent the top bead 32 from falling off. After being assembled, a part of the top bead 32 will protrude from the retaining ring 312. As Figure 4 shown, the retaining ring 312 of this embodiment is formed by inwardly contracting a part of the end hole of the through hole 311, thus eliminating the part of the retaining ring 312 and simplifying the structure. Threads are also provided in the through hole 311, and the top pin 34 is connected to the through hole 311 by threads.
[0033] As Figure 2 , Figure 3 shown, this structure has at least three advantages in this device:
[0034] First, by rotating the top pin 34 and adjusting the distance between the top pin 34 and the top bead 32, the pressing force of the top spring 33 can be changed, that is, the pressing force of the top bead 32 on the locking slot 21 can be adjusted. This structure can play a role in adjusting the fastening degree between the pipe body 1 and the pipe joint 2.
[0035] Second, since the surface of the top bead 32 is smooth and can rotate freely, during the process of rotating the locking portion 31, the top bead 32 can make the rotation of the locking portion 31 more smooth after it abuts against the locking slot 21, making the operation more smooth and labor-saving.
[0036] Third, since a part of the top bead 32 protrudes from the retaining ring 312 and this protruding part can be retracted, there is a certain reserved space between the locking portion 31 and the locking slot 21. This allows the locking portion 31 to rotate from the loose state to the locked state, that is, from the Figure 2 state to the Figure 3 state, and then it can be rotated inward by a small angle. The function of this small angle is to facilitate the use of the lock button. Because to move the retaining convex 111 from the notch 41 position to the card slot 42 position, the lock pin 4 must be rotated. To rotate the lock pin 4, the retaining convex 111 must completely pass through the notch 41, which requires the locking portion 31 to rotate a little further inward after it is parallel to the installation slot 11. The function of the top bead 32 just provides the condition for this. Moreover, when the retaining convex 111 is transferred to the card slot 42 position, under the action of the top spring 33, the locking portion 31 has a tendency to return to the state parallel to the installation slot 11. Therefore, in the state without applying external force, the locking portion 3 is parallel to the installation slot 11, and the retaining convex 111 can be completely engaged in the card slot 42 to prevent the lock pin 4 from rotating further, realizing the function of locking the locking portion 31.
[0037] It should be noted that the above descriptions such as "the blocking projection 111 is transferred from the notch 41 position to the card slot 42 position" are relative and are the relativity of motion. It is not to rotate the blocking projection 111, and those skilled in the art should be able to understand this.
[0038] The operation process is to appropriately press the locking block 3 so that the locking block 3 is parallel to the installation slot hole 11, then rotate the lock button to turn the blocking projection 111 to the card slot 42 position, release the pressed locking block 3, and under the action of the top spring 33, the locking block 3 rebounds to a state parallel to the installation slot, and the blocking projection 111 is stuck in the card slot 42. At this time, the lock button locks the locking block 3 and will not rotate easily.
[0039] Preferably, in this embodiment, a limit stop block 22 is provided on the outer wall of the pipe joint 2, and the limit stop block 22 is used to limit the distance that the pipe joint 2 extends into the pipe body 1. At the same time, in this embodiment, a strip-shaped protrusion 12 is also provided on the outer side wall of the pipe body 1, and the installation slot hole 11 is provided on the strip-shaped protrusion 12. When the wall thickness of the pipe body 1 is not thick enough, the setting of the strip-shaped protrusion 12 leaves enough height space for the installation slot hole 11, which is convenient for the use of the locking portion 31.
[0040] The present invention also provides a usage method for locking the device, including:
[0041] Step 1: Insert the pipe joint 2 into the pipe body 1, and pay attention to the corresponding positions of the installation slot hole 11 and the locking slot hole 21;
[0042] Step 2: Rotate the locking block 3 to make the locking portion 31 sink into the installation slot hole 11, and at the same time, the locking portion 31 is stuck in the locking slot hole 21. Pay attention to aligning the notch 41 with the blocking projection 111 when rotating the lock pin 4;
[0043] Step 3: Appropriately press the locking block 3 so that the locking block 3 is parallel to the installation slot hole 11, then rotate the lock button to turn the blocking projection 111 to the card slot 42 position, release the pressed locking block 3, and under the action of the top spring 33, the locking block 3 rebounds to a state parallel to the installation slot hole 11, and the blocking projection 111 is stuck in the card slot 42. At this time, the lock button locks the locking block 3 and will not rotate easily.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
