Description

Technical Field

[0001] The invention relates to a connector, in particular to an external card type detachable connector and an installation and use method thereof. Background Art

[0002] Existing quick connector structures such as the Chinese utility model patent with announcement number CN215568867U, a large flow quick connector for battery box coolant, focus on the attached Figure 4 Its main structure includes a conveying pipe, which is arranged horizontally. A joint connecting end is provided on the conveying pipe, and the joint connecting end is perpendicular to the conveying pipe. A baffle and two elastic arms are provided on the side of the joint connecting end. The two elastic arms are symmetrically located at the peripheral positions of the joint connecting end, and a protrusion is provided at the end of each elastic arm.

[0003] During the actual installation process, the sealing pipe end is sleeved on the joint connection end. At the same time, the protrusion of the elastic arm will be buckled and pulled at the end position of the sealing pipe end. After the installation is completed, as shown in the attached diagram of the existing patent, Figure 5 shown.

[0004] After long-term use, it is affected by at least the following two aspects: first, the elastic arm and the protrusion are made of plastic material, which is prone to aging and brittleness, and the limiting effect of the elastic arm on the sealed pipe end is weakened; second, the plug-in direction between the sealed pipe end and the joint connection end is vertical, and the hooking direction between the elastic arm and the sealed pipe end is also vertical. When the joint connection end and the sealed pipe end tend to separate, stress concentration is more likely to occur between the protrusion and the elastic arm, and the limiting effect of the elastic arm on the sealed pipe end will also be weakened.

[0005] Therefore, it is necessary to reconfigure the internal connection structure of the existing quick connector to improve the internal connection stability. Summary of the invention

When the second connecting end 7 of the second connecting pipe 6 is inserted into the connecting sleeve 11, the second engaging groove 8 on the second connecting end 7 can also correspond with the first through groove 3 and the third through groove 12 in a one-to-one correspondence.

[0058] See also Figure 1 as well as Figure 2 , and further comprises a metal clamping member 10, and the material of the metal clamping member 10 is preferably stainless steel. The metal clamping member 10 is formed by bending a metal rod in one piece. The metal clamping member 10 comprises at least two clamping arms 101, and the number of the clamping arms 101 shown in this embodiment is two.

[0065] In addition, a connecting block 16 is provided on the outer wall of the connecting sleeve 11, and a connecting slot 17 is provided on the side wall of the first connecting tube 1; when the second connecting end 7 on the second connecting tube 6 is plugged into the connecting sleeve 11, the connecting block 16 is engaged with the connecting slot 17, further improving the internal connection stability of the connector.

[0066] Embodiment 2:

[0067] A method for installing and using the external card-type detachable connector in the first embodiment:

[0068] Step 1: Place the seal 9 on the sealing step 13, and try to ensure that the seal 9 is stably attached to the sealing step 13;

[0069] Step 2: Install the connecting sleeve 11 in the first pipe opening 2, ensure that the positioning block 15 and the positioning groove 14 cooperate with each other, the connecting block 16 and the connecting groove 17 cooperate with each other, the end of the connecting sleeve 11 abuts against the sealing member 9 placed on the sealing step 13, and the third through groove 12 corresponds to the first through groove 3 one by one;

[0070] Step 3: insert the second connecting end 7 of the second connecting pipe 6 into the connecting sleeve 11 until the second engaging groove 8 on the second connecting end 7 corresponds to the first through groove 3 and the third through groove 12 one by one;

[0071] Step 4: gradually insert the metal engaging member 10 into the first connecting pipe 1 , and the engaging arm 101 on the metal engaging member 10 will pass through the first through groove 3 and the third through groove 12 in sequence and finally be inserted into the second engaging groove 8 .

[0072] Embodiment 3: The difference from Embodiment 1 is that:

[0073] See also Figure 1 as well as Figure 5 A disassembly member 18 is further provided in the first connecting tube 1, and the disassembly member 18 includes a disassembly driving member 181 and a disassembly column 19. The disassembly column 19 is slidably connected in each first through groove 3. The first connecting tube 1 is a cylindrical tube body, and the disassembly column 19 can slide along the first through groove 3 in an arc path.

[0074] See also Figure 1 , Figure 5 as well as Figure 6 The disassembly driving member 181 includes a force-applying end 1821 and a driving end 1822. The driving end 1822 is connected to the disassembly column 19. By applying a force to the outside of the first connecting tube 1 to the force-applying end 1821, the driving end 1822 can drive the disassembly column 19 to slide along the first through groove 3, and the disassembly column 19 can push the locking arm 101 to deform toward the outside of the first through groove 3.

[0075] Therefore, when the second connecting tube 6 needs to be removed from the first connecting tube 1, the user can apply force to the force-applying end 1821 of the disassembly driving member 181, and the entire disassembly driving member 181 moves toward the outside of the first connecting tube 1. The driving end 1822 of the disassembly driving member 181 can drive the disassembly column 19 to slide along the first through groove 3. At the same time, the disassembly column 19 can push the locking arm 101 to deform toward the outside of the first through groove 3, and the metal locking member 10 can be easily removed from the first connecting tube 1, and the disassembly is very convenient.

[0076] See also Figure 6 as well as Figure 7 The disassembly driving member 181 includes a disassembly driving sheet 182, and the disassembly driving sheet 182 is made of a deformable material, such as nylon.

[0077] There are two disassembly drive plates 182 corresponding to the first through grooves 3 one by one. The disassembly drive plates 182 are slidably connected in the first connecting tube 1. The drive end 1822 is located at the end position of the disassembly drive plate 182. The drive end 1822 on each disassembly drive plate 182 is connected to the corresponding disassembly column 19. The ends of the two disassembly drive plates 182 facing away from the disassembly column 19 are connected and located on the outer wall of the first connecting tube 1 to form a force-applying end 1821.

[0078] Therefore, firstly, the disassembly drive plate 182 is made of a deformable material, and during the movement of the disassembly drive plate 182, it can effectively fit the curved surface of the first pipe mouth 2 and move smoothly; secondly, force is applied to the force-applying end 1821, and the force-applying end 1821 can simultaneously drive the two disassembly drive plates 182 to move, and the two disassembly drive plates 182 can simultaneously drive the two corresponding disassembly columns 19 to slide, and the driving stability and sensitivity are relatively high.

[0079] See also Figure 1 as well as Figure 5 , a thrust piece 20 is provided on the force-applying end 1821, and the thrust piece 20 extends into the tension opening 103;

[0080] When the force-applying end 1821 is gradually pulled toward the side away from the first connecting tube 1 , the thrust piece 20 can abut against the pulling end 102 and drive the metal engaging member 10 to escape outward.

[0081] Therefore, when the force-applying end 1821 moves away from the outside of the first connecting tube 1, the thrust piece 20 on the force-applying end 1821 will resist the pulling end 102 at the pulling opening 103, and the thrust piece 20 will push the metal clamping piece to move toward the outside of the first tube opening 2; that is, by pulling the disassembly drive part 181, not only can the clamping arm 101 on the metal clamping part 10 be deformed outward, but also the metal clamping part 10 can be automatically disengaged outward, making disassembly more convenient.

[0082] Embodiment 4: The difference from Embodiment 3 is that:

[0083] See also Figure 5 as well as Figure 7 Two limit bars 21 are slidably connected in the first pipe opening 2. The limit bars 21 are connected to the disassembly columns 19 in a one-to-one correspondence. The sliding directions of the limit bars 21 and the disassembly columns 19 are consistent. The side walls of the limit bars 21 can limit the connection block 16 in the connection slot 17. Each limit bar 21 is provided with a first disassembly slot 22, which can communicate with the connection slot 17. Two second disassembly slots 23 corresponding to the connection slot 17 are provided in the first pipe opening 2.

[0084] When the disassembly column 19 pushes the locking arm 101 toward the outside of the first through groove 3 to deform, the disassembly column 19 drives the disassembly column 19 to slide, so that the connecting groove 17, the first disassembly groove 22, and the second disassembly groove 23 are connected, and the connecting block 16 can pass through the connecting groove 17, the first disassembly groove 22, the second disassembly groove 23 in sequence and escape from the first pipe mouth 2.

[0085] Therefore, when the first connecting tube 1 and the second connecting tube 6 are connected, the first disassembly groove 22 on the limiting strip 21 and the connecting slot 17 are misaligned with each other. At this time, the connecting block 16 on the connecting sleeve 11 can be stably connected to the connecting slot 17.

[0086] When the first connecting tube 1 and the second connecting tube 6 need to be removed, the force-applying end 1821 moves away from the outside of the first connecting tube 1, and the thrust piece 20 on the force-applying end 1821 abuts against the pulling end 102 at the pulling port 103. The thrust piece 20 pushes the metal clamping piece to move to the outside of the first tube port 2. At the same time, the disassembly column 19 drives the limit bar 21 to move, and the first disassembly groove 22 on the limit bar 21 is opposite to the connecting card groove 17. At this time, the connecting card block 16 on the connecting sleeve 11 can be connected through the connecting The connecting groove 17, the first disassembly groove 22, the second disassembly groove 23 and the connecting groove 17 are connected and disengaged from the first pipe mouth 2; that is, by pulling the disassembly driving member 181, firstly, the locking arm 101 on the metal locking member 10 can be deformed outward; secondly, the metal locking member 10 can be automatically disengaged outward; thirdly, the limiting strip 21 can be driven to slide at the same time, and the first disassembly groove 22, the second disassembly groove 23 and the connecting groove 17 on the limiting strip 21 are relative to each other, so as to facilitate the connecting sleeve 11 and the second connecting pipe 6 to be smoothly disassembled from the first pipe mouth 2.

[0087] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
