[0002] In the dispensing device (such as the dispensing valve) of the mobile phone camera module, the sealing ring used inside the dispensing valve is made of metal inside and rubber outside. Because the metal inside the sealing ring is not easily deformed, it is difficult to fit the sealing ring onto the push rod of the dispensing valve.

[0003] In related technologies, the sealing ring is usually put on the push rod of the glue valve manually. However, this method is inefficient and may result in the sealing ring not being put on properly, causing problems with the sealing performance of the glue valve. Therefore, a device is needed to put the sealing ring on the push rod of the glue valve and then put the push rod with the sealing ring on back onto the glue valve for use. Utility Model Content

[0004] This application provides a sealing ring auxiliary fitting device to solve the technical problem that the existing manual sealing ring fitting method has the problem of incomplete fitting position, resulting in poor sealing performance of the glue valve.

[0011] In one possible implementation, the support assembly further includes a base disposed at the second end of the fixing body, with the first end of the fixing body opposite to the second end of the fixing body; the base is provided with a receiving cavity and a dust cap covering the receiving cavity, the receiving cavity being used to receive the expansion cone.

[0012] In one possible implementation, the support assembly further includes a movable body that abuts against the periphery of the push rod on the side facing the fixed body;

[0013] The fixed body is provided with an installation groove, the movable body is embedded in the installation groove, and is connected to the fixed body through a detachable structure, so that the movable body has a first state of being separated from the fixed body and a second state of being fitted and connected to the fixed body.

[0014] In one possible implementation, the movable body is provided with a second guide groove, and the first guide groove is disposed opposite to the second guide groove.

[0015] In one possible implementation, in the second state, the first guide groove and the second guide groove are connected to form a closed groove.

[0020] The technical solutions provided in this application have the following advantages compared with the prior art:

[0021] This application provides a sealing ring assist fitting device. In use, the sealing ring is first placed in the positioning groove, then the expansion cone is placed in the first guide groove. Next, one end of a push rod abuts against the expansion cone and extends into the first guide groove, pushing the push rod so that one end slides from the first guide groove through the positioning groove, allowing the sealing ring to fit onto the push rod. During this process, the positioning groove limits the sealing ring, and the first guide groove limits the push rod. Through the friction between the expansion cone and the sealing ring, as well as the tension of the sealing ring itself, the sealing ring gradually expands, allowing it to smoothly fit onto the periphery of the push rod. This also prevents the sealing ring from cracking due to excessive local pressure initially. The push rod with the sealing ring fitted is then reinstalled on the valve. Compared to existing technologies, using a sealing ring assist fitting device improves efficiency, ensuring the sealing ring fits into the designated position on the push rod, thereby guaranteeing the sealing performance and operational reliability of the valve fitted with the push rod.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0035] To address the technical problem of incomplete sealing of the valve due to improper insertion of the sealing ring in existing manual methods, this application provides a sealing ring auxiliary insertion device. By limiting the push rod with a first guide groove and the sealing ring with a positioning groove, the sealing ring is inserted into the designated position of the push rod, thereby ensuring the sealing performance and operational reliability of the valve installed in the push rod.

[0036] like Figure 1 and Figure 2 As shown in the embodiment of this application, a sealing ring auxiliary fitting device includes a support component 1, a sealing ring 2, a push rod 3, and an expansion cone 4. The support component 1 includes a fixing body 11, on which a positioning groove 111 and a first guide groove 112 are provided. The positioning groove 111 communicates with the external environment and is used to restrict the movement of the sealing ring 2. For example, the shape of the positioning groove 111 can be set to circular, and the diameter of the circular positioning groove 111 can match the outer diameter of the sealing ring 2, thereby positioning the sealing ring 2; the shape of the positioning groove 111 can also be set to square, and the diameter of the inscribed circle of the square positioning groove 111 can match the outer diameter of the sealing ring 2, thereby positioning the sealing ring 2; of course, the positioning groove 111 can also be set to other shapes, and this application does not make specific limitations on this.

[0037] The first guide groove 112 extends from the first end of the fixing body 11 into the interior of the fixing body 11 and communicates with the positioning groove 111. The first guide groove 112 can extend in the vertical direction.

[0038] The sealing ring 2 is disposed in the positioning groove 111, which is connected to the external environment. After the sealing ring 2 is fitted onto the push rod 3, another sealing ring 2 can be placed on the positioning groove 111 for the next round of use. The push rod 3 is slidably disposed on the first guide groove 112, and the expansion cone 4 abuts against the end of the push rod 3 near the first guide groove 112.

[0039] For ease of explanation and understanding, the vertical direction can be represented by the Z-direction shown in the figure. It is understood that when needed, the sealing ring 2 is first placed into the positioning groove 111, then the expansion cone 4 is placed into the first guide groove 112. Next, one end of the push rod 3 abuts against the expansion cone 4 and extends into the first guide groove 112, pushing the push rod 3 so that one end of the push rod 3 slides from the first guide groove 112 through the positioning groove 111, allowing the sealing ring 2 to fit onto the push rod 3. During this process, because the positioning groove 111 limits the sealing ring 2 and the first guide groove 112 limits the push rod 3, the sealing ring 2 gradually expands due to the friction between the expansion cone 4 and the sealing ring 2, as well as the tension of the sealing ring 2 itself. This allows the sealing ring 2 to smoothly fit onto the periphery of the push rod 3, while also preventing the sealing ring 2 from cracking due to excessive local pressure initially. The push rod 3 with the sealing ring 2 then is reinstalled on the valve for use. Compared to existing technologies, the use of a sealing ring auxiliary fitting device can improve efficiency, allowing the sealing ring 2 to fit into the designated position of the push rod 3, thereby ensuring the sealing performance and operational reliability of the valve installed in the push rod 3.

[0040] The fixing body 11 can be cylindrical or plate-shaped; this application does not impose any specific restrictions on it.

[0041] In some embodiments, such as Figure 2 As shown, the expansion cone 4 has an expansion portion 41, the circumference of which gradually decreases away from the push rod 3. During the sliding process of the push rod 3 in the first guide groove 112, the sealing ring 2 first fits into the smaller end of the expansion cone 4. Under the frictional force between the expansion cone 4 and the sealing ring 2, as well as the tension of the sealing ring 2 itself, the sealing ring 2 gradually expands, allowing it to smoothly fit into the circumference of the push rod 3. This also prevents the sealing ring 2 from cracking due to excessive initial pressure. Thus, the force exerted by the sealing ring 2 on the push rod 3 is relatively uniform, thereby ensuring the sealing performance after the valve is installed.

[0042] The expansion cone 4 may also include a guide portion 42, which may be integrally formed with the expansion cone 4. The guide portion 42 is connected to the end of the expansion cone 4 near the push rod 3. The guide portion 42 is slidably engaged with the first guide groove 112, thereby playing a guiding role and preventing the expansion cone 4 from deflecting during the sliding process of the first guide groove 112.

[0043] In some embodiments, such as Figure 1 and Figure 2As shown, the support assembly 1 also includes a base 12, which is disposed at the second end of the fixing body 11. The first end of the fixing body 11 is disposed opposite to the second end of the fixing body 11. For example, the first end of the fixing body 11 is the top end, and the second end of the fixing body 11 is the bottom end. The base 12 is disposed at the bottom end of the fixing body 11. The base 12 is provided with a receiving cavity 121 and a dust cap 122 covering the receiving cavity 121. The receiving cavity 121 is used to receive the expansion cone 4.

[0044] First, remove the expansion cone 4 from the receiving cavity 121 of the base 12. Then, place the expansion cone 4 into the first guide groove 112. Next, extend one end of the push rod 3 into the first guide groove 112 and push the push rod 3. This causes the expansion cone 4 to slide from the first guide groove 112 through the positioning groove 111, allowing the sealing ring 2 to be fitted onto the push rod 3. Under the friction between the expansion cone 4 and the sealing ring 2, as well as the tension of the sealing ring 2 itself, the sealing ring 2 gradually expands, allowing the sealing ring 2 to be smoothly fitted onto the periphery of the push rod 3. This also prevents the sealing ring 2 from being deformed due to excessive pressure initially.

[0045] Optionally, the base 12 and the fixing body 11 can be integrally formed. The side of the base 12 away from the fixing body 11 can be set as a plane. When the base 12 is placed on the operating table, the plane can increase the contact area between the base 12 and the operating table, thereby improving the stability of operation.

[0046] It should be noted that the height of the accommodating cavity 121 can be set to be slightly greater than the thickness of the expansion cone 4 so that the dust cover can fit over the accommodating cavity 121.

[0047] In some embodiments, such as Figure 1 and Figure 2As shown, the support assembly 1 also includes a movable body 13, the side of which faces the fixed body 11 and abuts against the periphery of the push rod 3. The fixed body 11 has a mounting groove 113 that communicates with the positioning groove 111. The movable body 13 is embedded in the mounting groove 113 and connected to the fixed body 11 via a detachable structure 5, allowing the movable body 13 to have a first state separated from the fixed body 11 and a second state of being fitted and connected to the fixed body 11. For example, if the fixed body 11 is cylindrical, the cross-section of the mounting groove 113 can be semi-circular to allow the movable body 13 to fit and connect with the fixed body 11. Before use, the movable body 13 is embedded in the mounting groove 113 and connected to the fixed body 11 via the detachable structure 5, and is in the second state of being fitted and connected to the fixed body 11. In use, the movable body 13 is detached from the fixed body 11 via the detachable structure 5 so that the sealing ring 2 can be placed into the positioning groove 111. Then, the movable body 13 is connected to the fixed body 11 as a whole via the detachable structure 5. The side of the movable body 13 facing the fixed body 11 abuts against the push rod 3, so that during the sliding of the push rod 3 in the first guide groove 112, the movable body 13 can exert a certain pressure on the push rod 3, preventing the push rod 3 from tilting and affecting the normal insertion of the sealing ring 2.

[0048] In some embodiments, the movable body 13 is provided with a second guide groove 131, and the first guide groove 112 is disposed opposite to the second guide groove 131. The second guide groove 131 guides the push rod 3, allowing the push rod 3 to slide downward in the vertical direction, which is conducive to the normal insertion of the sealing ring 2.

[0049] In some embodiments, in the second state, the movable body 13 has the first guide groove 112 and the second guide groove 131 engaging to form a closed groove. For example, the push rod 3 has a circular cross-section, the first guide groove 112 can be set as a semi-circle, and the second guide groove 131 can be set as a semi-circle. When the movable body 13 is fitted and connected to the fixed body 11, the first guide groove 112 and the second guide groove 131 engage to form a closed circular groove. Thus, the first guide groove 112 and the second guide groove 131 together guide the push rod 3, allowing the push rod 3 to slide along the vertical direction so that the sealing ring 2 fits around the periphery of the push rod 3.

[0050] In some embodiments, such as Figure 3As shown, the detachable structure 5 includes a fastener 53, a first protrusion 51, and a second protrusion 52. The first protrusion 51 is disposed on the fixed body 11, and the second protrusion 52 is disposed on the movable body 13. The fastener 53 (bolt, pin) is used to fix the first protrusion 51 and the second protrusion 52. For example, the first protrusion 51 may be provided with a first threaded hole, and the second protrusion 52 may be provided with a second threaded hole. The fastener 53 is a bolt, which is sequentially connected to the second threaded hole of the second protrusion 52 and the first threaded hole of the first protrusion 51 to realize the detachable connection between the movable body 13 and the fixed body 11. Multiple first protrusions 51 and multiple second protrusions 52 may be provided, with multiple first protrusions 51 corresponding to multiple second protrusions 52 one-to-one. For example, a first pin hole may be provided on the first protrusion 51, a second pin hole may be provided on the second protrusion 52, and a fastener 53 may be a pin shaft. The pin shaft is connected to the second pin hole of the second protrusion 52 and the first pin hole of the first protrusion 51 in sequence, so as to realize the detachable connection between the movable body 13 and the fixed body 11.

[0051] In one embodiment (not shown in the figure), the detachable structure 5 includes a third protrusion and a snap fastener. The third protrusion is disposed on the fixed body 11, and the snap fastener is disposed on the movable body 13. The third protrusion has a slot for engaging with the snap fastener. The detachable connection between the movable body 13 and the fixed body 11 is achieved through the snap-fit ​​connection between the slot and the snap fastener.

[0052] In some embodiments, such as Figure 4 As shown, the fixed body 11 is provided with a third guide groove 114. One end of the third guide groove 114 is connected to the positioning groove 111, and the other end extends away from the first guide groove 112. The depth of the third guide groove 114 is designed according to the insertion height of the sealing ring 2 on the push rod 3. That is, when one end of the push rod 3 is inserted into the first guide groove 112 and the push rod 3 is pushed, the one end of the push rod 3 slides through the first guide groove 112 and the positioning groove 111 in sequence until it reaches the bottom of the third guide groove 114, so that the sealing ring 2 is fitted into the designed position of the push rod 3.

[0053] In some embodiments, the axial direction of the first guide groove 112 is coaxial with the axial direction of the positioning groove 111. The coaxial arrangement of the first guide groove 112 and the positioning groove 111 ensures that the push rod 3 can be aligned with the positioning groove 111 during the sliding process of the first guide groove 112, allowing the sealing ring 2 to be smoothly fitted onto the push rod 3. Similarly, the axial direction of the third guide groove 114 is coaxial with the axial direction of the positioning groove 111. This coaxial arrangement ensures that the push rod 3 remains aligned with the positioning groove 111 during the sliding process of the third guide groove 114, allowing the sealing ring 2 to be smoothly fitted onto the push rod 3.
