Description

Technical Field

[0001] The present disclosure relates to the field of installation, and in particular to an installation tool for assisting in establishing a pipe connection structure. Background Art

[0002] Usually, a connection part is provided at the upper end of the radiator housing, which is used to connect with the quick-connect fitting connected to the delivery pipe. This quick-connect fitting is pre-installed with a spring. During installation, the installation personnel usually connect manually. Due to uneven force application, the spring may partially pop out and fail to rebound into place, resulting in connection failure. For this reason, it needs to be dismantled for reinstallation, wasting time for inspection and reinstallation.

[0003] To this end, it is desirable to provide an installation tool that can enable the spring to rebound correctly to ensure that the quick-connect connector is effectively connected. Utility Model Content

[0004] In order to solve the above technical problems, the task of the present disclosure is to provide an installation tool for assisting in establishing a pipe connection structure to ensure that the spring rebounds correctly and an effective connection is made without further inspection.

[0005] In one aspect, the present disclosure provides an installation tool, which is used to assist in establishing a pipe connection structure. The pipe connection structure includes a connection portion and a quick-connect joint matched with the connection portion. A spring is pre-installed in the quick-connect joint, and the spring has a spring exposure portion exposed from a slender opening of the quick-connect joint. The connection portion has a spring receiving portion for receiving the spring. The installation tool includes an installation head, and the installation head includes a main engagement portion for at least partially engaging the outer contour of the quick-connect joint from above and a protruding probe portion extending distally from the main engagement portion parallel to the central axis of the installation tool. The protruding probe portion is configured to push the spring exposure portion so that the spring rebounds and is located in the spring receiving portion during the installation process of installing the quick-connect joint on the connection portion with the aid of the installation tool when the main engagement portion is engaged with the outer contour of the quick-connect joint.

[0006] Therefore, using the installation tool disclosed in the present invention, the main joint part can apply a uniform downward force to the quick connect connector, reducing the chance of excessive spring popping out, and the downward force works together with the inward force applied by the protruding probe part to the exposed part of the spring, prompting the spring to fully rebound so that it can be installed in the spring receiving part, thereby achieving an effective connection.

[0007] In one or more embodiments, the main joint portion has an inner surface that conforms to the outer contour of the quick connect connector; and / or, in a direction away from the protruding probe portion, the main joint portion includes, in sequence, a first section, a second section, and a third section that are integrally formed in a stepped structure, and the inner surfaces of the first section, the second section, and the third section are all arc-shaped and combined to form the inner surface of the main joint portion.

[0008] Thus, the configuration of the main joint can provide a sufficiently large contact surface for the quick-connect joint to provide uniform force distribution. Moreover, the arc-shaped inner surface can also wrap around the outer contour of the quick-connect joint to prevent the quick-connect joint from shaking.

[0009] In one or more embodiments, the protruding probe portion has a planar inner surface; and / or the width of the protruding probe portion is equal to or less than the width of the slender opening; and / or the length of the protruding probe portion is such that the protruding probe portion extends at least beyond the spring exposure portion when the main joint portion engages with the outer contour of the quick connect connector.

[0010] Thus, the structure and size of the protruding probe portion enable the protruding probe portion to effectively apply an inward force to the spring exposed portion.

[0011] In one or more embodiments, the mounting head has a positioning groove, which is configured to be able to be clamped on the outer flange of the connecting end of the quick connector connected to the conveying pipe when in use; and / or the extension direction of the positioning groove is orthogonal to the protruding direction of the protruding probe part.

[0012] Thus, the positioning groove facilitates quick and accurate positioning of the installation tool.

[0013] In one or more embodiments, the width of the positioning groove is within 1 mm greater than the width of the outer flange.

[0014] Thus, the positioning groove can perform a small amount of relative movement with respect to the outer flange, which allows fine adjustment of the position during pre-positioning on the one hand, and allows operation of the installation tool to cause the protruding probe part to actively apply an inward force to the exposed spring part on the other hand.

[0015] In one or more embodiments, the installation tool also includes an auxiliary joint portion formed integrally with the main joint portion, the auxiliary joint portion extending laterally from the main joint portion relative to the protruding probe portion, and the configuration of the inner surface of the auxiliary joint portion conforms to the outer contour of the conveying pipe connected to the quick-connect connector; and / or the outer contour of the auxiliary joint portion has a planar contour portion.

[0016] Thus, the auxiliary engagement portion provides an additional contact surface to more evenly distribute the downward force applied by the installation tool to the quick-connect connector, reducing the chance of localized excessive spring ejection.

[0017] In one or more embodiments, the installation tool further comprises a handle integrally formed with the installation head; and / or the handle has a first central hole for reducing the weight of the installation tool.

[0018] Thus, the structure of the handle facilitates providing a structurally strong and lightweight installation tool.

[0019] In one or more embodiments, the installation tool also includes a hand-held portion, which is arranged on the first end of the handle opposite to the installation head; and / or the hand-held portion is detachably connected to the first end of the handle; and / or the hand-held portion is connected to the handle by means of a threaded hole connecting a screw to the first end of the handle; and / or the hand-held portion has an integrally formed spherical portion and a cylindrical portion, the spherical portion is suitable for being held by hand to apply a force to the installation head along the central axis of the installation tool, and the cylindrical portion is suitable for being mounted on the first end of the handle.

[0020] Thus, the structure of the handle and the hand-held portion is convenient for providing an installation tool with a simple structure and convenient assembly. Moreover, the structure of the hand-held portion is convenient for the installer to operate the installation tool comfortably and firmly with one hand.

[0021] In one or more embodiments, the connecting portion is a tank fluid joint of the radiator tank extending vertically upward from the tank body.

[0022] In one or more embodiments, viewed in a direction away from the quick-connect connector, the connecting portion sequentially includes a first cylindrical portion, a second tapered portion, a third cylindrical portion, and the spring receiving portion located between the second tapered portion and the third cylindrical portion.

[0023] Therefore, the structure of the connecting part can prevent the spring from locally excessively rebounding when passing through the second conical part under the action of downward force, and further promote the spring to fully rebound and be located in the spring receiving part between the second conical part and the third cylindrical part through the inward force applied by the protruding probe part to the exposed part of the spring, thereby achieving effective connection.

[0039] Figure 1 FIG. 1 is a schematic diagram showing a pipe connection structure of a radiator housing 1. Figure 1 The schematic diagram shown is a diagram of a connection portion 10 of a radiator box 1 to be connected to a quick-connect connector 20 that has been connected to a delivery pipe 30 .

[0040] Reference Figure 1 like Figure 2 As shown, the connection portion 10 provided at the upper end of the radiator housing 1 is used to connect with the quick-connect connector 10 connected to the delivery pipe 30. The delivery pipe 30 can be used to transport liquid or gas. For example, the delivery pipe can be used to transport coolant, such as water. Due to the relatively small installation space, the installation operation is limited.

[0041] Reference Figure 2 The quick-connect connector 20 may include a first cylindrical section 22 and a second cylindrical section 24 having two different diameters arranged in a stepped manner, and an elbow section 25 that is bent toward the delivery pipe 30 to connect with the delivery pipe 30. Figure 2 In the example shown, the first cylindrical section 22, the second cylindrical section 24 and the elbow section 25 are integrally formed, and their outer surfaces can form the outer contour of the quick connector 20. A spring is pre-installed in the first cylindrical section 22. The quick connector 20 has an elongated opening 28 in the lower portion of the first cylindrical section 22. A portion of the spring (referred to as the spring exposed portion 26) can be exposed from the elongated opening 28 of the quick connector, that is, the spring exposed portion 26 is visible from the outside of the quick connector through the elongated opening. The provision of the elongated opening 28 also facilitates the removal of the spring therefrom to disassemble the quick connector 20.

[0042] Reference Figure 2 The connection part 10 at least has a first cylindrical part 12, a second conical part 14, a third cylindrical part 16 and a spring receiving part 18. The first cylindrical part 12, the second conical part 14, the third cylindrical part 16 and the spring receiving part 18 can all be cylindrical. The spring receiving part 18 is configured in the form of an annular recess located between the second conical part 14 and the third cylindrical part 16, and is used to receive a spring to be pre-installed in the quick connector 20 to ensure that the quick connector 20 is firmly installed in place on the connection part 10.

[0043] In the process of establishing the pipe connection structure of the radiator box 1, due to the limited installation space, the installer usually presses the quick connector 20 downward onto the connection part 10 with both hands. The spring pre-installed in the quick connector 20 pops outward under the extrusion force when passing through the second tapered part 14 downward, and the spring pops outward when at least a part of the spring is about to pass over the tapered connection part 14. After that, when the center line of the spring vertically passing through the cross section is about to pass over the tapered connection part, the spring tends to rebound to be located in the spring receiving part 18. However, since the downward pressure applied by the installer's hands to the quick connector 20 from above is not evenly distributed, the spring cannot rebound correctly due to excessive local pop-up amount, resulting in connection failure. In particular, when the protrusion amount of the spring exposed part 26 protruding from the quick connector 20 through the elongated opening 28 is too large, it is more likely to cause the spring to fail to rebound correctly and be located in the spring receiving part 18, so that the quick connector 20 cannot be firmly connected to the connection part 10. This situation of the spring not rebounding in place often occurs, so the installer has to check after each installation, wasting a lot of inspection time. If the connection fails, the installer has to laboriously remove and reinstall it, further wasting manpower, material resources and time.

[0044] In order to solve the above problems, the present disclosure provides an installation tool 100 that allows the spring to rebound correctly to ensure that the quick-connect connector is effectively connected. The installation tool is used to assist in establishing a pipe connection structure of a radiator box. In short, it can be used to assist in installation. Figure 4AThe installation tool 100 includes a mounting head 110 , a handheld portion 120 , and a handle 130 connecting the mounting head 110 and the handheld portion 120 .

[0045] Reference Figures 3 to 4C , the mounting head 110 has a partially cylindrical body 112. The mounting head 110 includes a main engagement portion 114 for at least partially engaging the outer contour of the quick connector 20 from above, and a protruding probe portion 116 extending distally from the main engagement portion parallel to the central axis of the mounting tool. The protruding probe portion 116 has a planar inner surface. During the installation process of installing the quick connector 20 on the connecting portion 10 with the aid of the mounting tool 100, when the main engagement portion 116 engages with the outer contour of the quick connector, the spring exposed portion 26 is pushed so that the spring rebounds to the spring receiving portion 18. In short, the protruding probe portion 116 is configured to push the spring rebound to the spring receiving portion 18 during the auxiliary installation process of the mounting tool 100. The term "distal" refers to a direction away from the handle 130 and the hand-held portion 120, that is, as shown in FIG. Figure 4C Thus, by using the installation tool disclosed in the present invention, the main joint portion 114 can apply a uniform downward force to the quick-connect connector, reducing the probability of excessive spring popping out, and the downward force and the inward force applied by the protruding probe portion 116 to the spring exposed portion 26 work together to cause the spring to fully rebound to be installed in the spring receiving portion 18, thereby achieving an effective connection between the connection portion 10 of the radiator box and the quick-connect connector 20.

[0046] When the installation tool 100 is used for auxiliary installation, the protruding probe portion 116 can extend through the elongated opening 28 of the quick-connect connector, so that the planar inner surface of the protruding probe portion 116 can apply an inward force to the spring exposed portion 26. In other words, during the pipe connection process, the spring exposed portion 26 pops outward through the elongated opening and abuts against the planar inner surface of the protruding probe portion 116, thereby, the planar inner surface of the protruding probe portion 116 can apply an inward reaction force to the spring exposed portion 26, on the one hand, preventing the spring exposed portion 26 from being excessively popped out, and on the other hand, prompting the spring to fully rebound to be seated in the spring receiving portion 18 when the center line of the spring is about to pass the second tapered connecting portion 14.

[0047] The width of the protruding probe portion 116 can be designed to be equal to or less than the width of the elongated opening 28 so that the inward force can be better applied to the spring exposed portion 26. The length of the protruding probe portion 116 is designed to extend at least beyond the spring exposed portion 18 when the main joint 114 is engaged with the outer contour of the quick connector 20, so that the planar inner surface of the protruding probe portion 116 applies an inward force to the spring exposed portion 26. However, the length of the protruding probe portion 116 cannot be too large to avoid interference with other parts of the quick connector 10. The thickness of the protruding probe portion 116 is designed to make the protruding probe portion have sufficient strength and not easy to break. If the thickness of the protruding probe portion 116 is too thin, it is easy to accidentally scratch the installer on the one hand, and it is easy to break on the other hand. Thus, the structure and size of the protruding probe portion enable the protruding probe portion to effectively apply an inward force to the spring exposed portion.

[0048] The main joint portion 114 has an inner surface that conforms to the outer contour of the quick connector 20. Specifically, in the direction away from the protruding probe portion 116, the main joint portion 114 includes, in sequence, a first section, a second section, and a third section that are integrally formed in a stepped structure. The inner surfaces of the first section, the second section, and the third section are all in an arc shape and are combined to form the inner surface of the main joint portion. In other words, the shape of the inner surface of the main joint portion 114 conforms to the outer contours of the first cylindrical section 22, the second cylindrical section 24, and the elbow section 25, so that at least a portion of the inner surface of the main joint portion 114 can abut against the outer contour of the quick connector 20 to provide a sufficiently large contact surface, thereby providing a uniform force distribution to the quick connector 20. In addition, the arcuate inner surfaces of the first section, the second section, and the third section can also surround the outer contours of the first cylindrical section 22, the second cylindrical section 24, and the elbow section 25 of the quick connector 20 to prevent the quick connector 20 from shaking. Therefore, during the auxiliary installation process of the installation tool, the main joint 114 can fully contact the outer contour of the quick connector 20 from top to bottom to provide uniform force distribution to the quick connector 20.

[0049] The installation tool 100 also includes an auxiliary engagement portion 115 that is integrally formed with the main engagement portion 114. The auxiliary engagement portion 115 extends laterally from the main engagement portion 114 relative to the protruding probe portion 116. The configuration of the inner surface of the auxiliary engagement portion 115 conforms to the outer contour of the delivery tube 30 connected to the quick connector 20 so as to provide an additional contact surface. Specifically, the auxiliary engagement portion 115 may be configured to at least partially engage the outer surface of the first connection portion 32 of the delivery tube 30 during the auxiliary installation process of the installation tool 100. Thus, the auxiliary engagement portion 115 provides an additional contact surface so that the downward force applied by the installation tool 100 to the quick connector 20 is more evenly distributed, thereby reducing the probability of localized excessive popping of the spring. The outer contour of the auxiliary engagement portion 115 may be non-arc-shaped. For example, as Figure 4B As shown, the outer contour of the auxiliary joint portion 115 may be partially cut away to form a contour portion having a plane to reduce weight.

[0050] like Figure 2 As shown, the connection end of the elbow section 25 of the quick connector 20 connected to the delivery pipe 30 is provided with an outer flange 27. Figure 3 and Figure 4C , the main joint portion 114 is provided with a positioning groove 118. The extending direction of the positioning groove 118 is orthogonal to the protruding direction of the protruding probe portion 116. The positioning groove 118 can be configured to be snapped onto the outer flange 27, so as to facilitate good positioning of the installation tool 100 during use, so that the protruding probe portion 116 can just extend through the elongated opening 28 to push the spring to rebound and be located in the spring receiving portion 18. Therefore, the positioning groove 118 facilitates quick and accurate positioning of the installation tool.

[0051] The width of the positioning groove 118 can be slightly larger than the width of the outer flange 27, for example, within 1 mm, so as to allow the positioning groove 118 to perform a small relative movement relative to the outer flange 27 during operation. This relative movement allows the position to be fine-tuned during pre-positioning on the one hand, and on the other hand allows the operation of the installation tool to make the protruding probe part actively apply an inward force to the spring exposed part, thereby promoting the spring to rebound better and be located in the spring receiving part 18.

[0052] refer to Figure 4C , the installation tool 100 includes a handle 130 and a handheld portion 120. The handheld portion 120 is detachably connected to the first end of the handle 120. The handle 130 of the installation tool 100 can be formed integrally with the installation head 110. In an embodiment not shown, the handle 130 can be non-detachably connected to the installation head 110 at the second end, such as welding. Alternatively, the handle 130 can be detachably connected to the installation head 110 at the second end, such as threaded connection. The handle 130 can have a first center hole 132 for reducing the weight of the installation tool. The handle 130 can have a threaded hole 134 at the first end to be detachably connected to the handheld portion 120 by means of a screw 140. As a result, the structure of the handle facilitates providing a structurally strong and weight-reduced installation tool.

[0053] The structure of the hand-held portion 120 is suitable for being held by hand, so that the installer can comfortably and firmly apply a force along the central axis L1 of the installation tool 100. For example, the hand-held portion 120 may have a spherical portion and a cylindrical portion that are integrally formed. The spherical portion is suitable for being held by hand to apply a force to the installation head along the central axis of the installation tool, and the cylindrical portion is suitable for being sleeved on the first end of the handle 120. The material of the hand-held portion 120 is suitable for providing the installer with a comfortable and stable grip. For example, the hand-held portion 120 can be made of a rubber material, thereby not only providing a comfortable grip, but also reducing the weight of the installation tool 100. The installation head 110 and the handle 130 are generally made of a metal material to provide sufficient strength for the installation tool 100. Thus, the structure and material of the hand-held portion facilitate the installer to comfortably and firmly operate the installation tool with one hand.

[0054] When using the installation tool 100 for auxiliary installation, the installation personnel's operation steps are as follows. First step: put the first cylindrical section 22 of the quick connector 20 connected to the delivery pipe 30 onto the first cylindrical section 12 of the connection part 10. Second step: the installation personnel hold the hand-held part 120 of the installation tool 100 with one hand, approach the quick connector 20 from above, and snap the positioning groove 115 onto the outer flange 27 to pre-position the installation tool 100. Third step: the installation personnel abut the main engaging part 114 of the installation tool 100 against the outer contour of the quick connector 20, so that the inner surface of the main engaging part 114 engages with the first cylindrical section 22, the second cylindrical section 24 and the elbow section 25 of the quick connector 20. At the same time, the auxiliary engaging part 115 can at least partially engage with the outer surface of the first connection part 32 of the delivery pipe 30. Thus, the main engaging part 114 and the auxiliary engaging part 115 cooperate to provide a sufficient contact surface for the quick connector 20. Step 4: The installer can apply a downward force from the hand-held portion 120 along the central axis L1 of the installation tool 100 with one hand. Due to the sufficiently large contact surface provided by the main joint portion 114 and the auxiliary joint portion 115, the downward force can be evenly distributed on the quick connector 20, which can ensure that the spring is uniform in all directions when it moves downward along the second tapered portion 14 of the connecting portion 10, and it is not easy to fail to rebound correctly. Step 4: When the spring moves through the second tapered portion 14, it pops outward under the action of the squeezing force until it abuts against the protruding probe portion 116 of the installation tool 100 and is subjected to the inward reaction force applied by the protruding probe portion 116. Under the combined action of the inward force and the downward force continuously applied by the installer, the spring effectively rebounds into the spring receiving portion 18, thereby reaching the working position. In this way, the effective connection between the quick connector 20 and the connecting portion 10 is ensured. Step 5: Remove the installation tool 100 from above. In order to ensure that the spring rebounds more effectively and there is no need to further check whether an effective connection is made, before removing the installation tool 100, the installer can push the hand-held portion 120 laterally so that the protruding probe portion 116 can actively move toward the elongated opening 28 to apply an inward force to the exposed spring portion 26, which can more effectively push the spring back into place. Due to this action, it can be ensured that the spring rebounds correctly into place without further inspection.

[0055] Thus, the installation personnel can complete the installation with only one hand through the installation tool with a simple structure, which is convenient to operate. The setting of the protruding probe part 116 ensures that the spring rebounds accurately into the spring receiving part 18 to achieve effective connection, and no further inspection is required, thereby saving inspection time. In addition, the installation tool 100 has a low manufacturing cost and is easy to promote and use.
