Description

Technical Field

[0001] This utility model relates to the technical field of thermostatic valve cores, and in particular to a novel thermostatic valve core elastic retaining ring assembly device. Background Technology

[0002] A thermostatic valve core is a device that automatically adjusts the mixing ratio of hot and cold water to maintain the temperature of the mixed water at a set temperature.

[0003] like Figure 7 The image shows a thermostatic valve core component. The adjustment structure 21 needs to be installed inside the valve body 22. A gasket 23 needs to be installed between the adjustment structure 21 and the valve body 22. After the adjustment structure 21 passes through the top of the valve body 22, a retaining ring 24 needs to be fitted onto the adjustment structure 21.

[0004] However, since the gasket 23 is installed inside the valve body 22, it is difficult to detect whether the gasket 23 is missing after assembly, which can easily lead to defects due to the omission of the gasket 23. Secondly, the retaining ring 24 has an elastic structure, making it difficult to quickly install the retaining ring 24 onto the adjusting structure 21. Therefore, in order to solve the above technical problems, a novel thermostatic valve core elastic retaining ring assembly device of this application is proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new type of thermostatic valve core elastic retaining ring assembly device that can be quickly assembled and avoids the omission of gaskets.

[0006] The technical solution adopted in this utility model is:

[0007] A novel thermostatic valve core elastic retaining ring assembly device includes:

[0008] The base has a sliding groove inside, and a material retainer is provided on one side of the base, which can be adjusted to extend into the sliding groove;

[0009] A detection assembly includes a detection seat, a marker post, a first elastic element, and a lever. The detection seat is disposed on one side of the base, and the marker post passes through the detection seat. The first elastic element abuts against both the detection seat and the marker post, and is used to push the marker post so that the top end of the marker post retracts into the detection seat. The lever is rotatably mounted on the base, with one end extending into the sliding groove and the other end abutting against the bottom end of the marker post.

[0010] A material-carrying assembly includes a core column, a slide block, and a second elastic element. The core column is disposed on the inner bottom wall of the slide groove, and the slide block is slidably disposed within the slide groove, with the core column passing through the slide block. The second elastic element abuts against the slide block and the base respectively. The second elastic element is used to push the slide block so that the top end of the slide block extends from the top end of the core column. The core column is used to support the adjustment structure, and the slide block is used to support the valve body. When the valve body is pushed by force to descend relative to the core column, the top end of the adjustment structure extends from the top end of the valve body, and the material-locking element engages with the slide block, and the valve body abuts against the lever.

[0011] Optionally, when the top of the slide extends from the top of the core column, the core column and the slide together form a material loading groove, and the adjustment structure is adapted to be accommodated in the material loading groove.

[0012] Optionally, the outer side wall of the core column is provided with a plurality of protruding ridges, and the inner side wall of the slide is provided with a plurality of grooves, with each of the protruding ridges corresponding to and passing through each of the grooves.

[0013] Optionally, the slide has a locking hole along the radial direction, and an inclined top surface is formed between the bottom end of the slide and the locking hole. When the valve body is pushed by force to descend relative to the core column, the inclined top surface pushes the locking component, thereby causing the locking component to engage with the locking hole.

[0014] Optionally, the core post is provided with a locking step, which is used to engage the slide block.

[0015] Optionally, an axial clearance groove is also provided on the outer side wall of the slide block, and one end of the lever extending into the slide groove is located in the clearance groove.

When the pressure rod is subjected to force, the pressure groove pushes the retaining ring to engage with the adjustment structure.

[0018] Optionally, the detection assembly further includes a guide sleeve disposed on the detection seat, and the marking post is adapted to pass through the guide sleeve.

[0019] Optionally, the end of the marker post that abuts against the lever is configured as a spherical surface.

[0020] The beneficial effects of this utility model are:

[0021] This utility model discloses a novel thermostatic valve core elastic retaining ring assembly device, comprising a base, a detection component, and a material loading component. The base has a sliding groove, and a material retaining component is provided on one side of the base, adjustablely extending into the sliding groove. The detection component includes a detection seat, a marker post, a first elastic element, and a lever. The detection seat is located on one side of the base, the marker post passes through the detection seat, and the first elastic element abuts against both the detection seat and the marker post. The first elastic element pushes the marker post, causing its top end to retract into the detection seat. The lever is rotatably mounted on the base, with one end extending into the sliding groove. The other end abuts against the bottom of the marker post. The material-carrying assembly includes a core column, a slide block, and a second elastic element. The core column is disposed on the inner bottom wall of the slide groove, and the slide block is slidably disposed within the slide groove, with the core column passing through the slide block. The second elastic element abuts against both the slide block and the base. The second elastic element is used to push the slide block so that the top of the slide block extends from the top of the core column.

When the valve body is subjected to force and pushes the slide block down relative to the core column, the top of the adjustment structure extends from the top of the valve body, and the material-locking element engages with the slide block, and the valve body abuts against the lever. Thus, using the novel thermostatic valve core elastic retaining ring assembly device of this application, the adjustment structure, valve body, gasket, and retaining ring can be quickly assembled into a thermostatic valve core component, and the omission of the gasket can be effectively avoided.

[0031] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0032] like Figures 1 to 3 As shown, a novel thermostatic valve core elastic retaining ring assembly device 10 includes a base 100, a detection component 200, and a loading component 300. A groove 110 is formed inside the base 100, and a retaining element 400 is provided on one side of the base 100, which can be adjusted to extend into the groove 110. The detection component 200 includes a detection seat 210, a marker post 220, a first elastic element 230, and a lever 240. The detection seat 210 is disposed on one side of the base 100, and the marker post 220 passes through the detection seat 210. The first elastic element 230 abuts against both the detection seat 210 and the marker post 220, and is used to push the marker post 220 so that the top end of the marker post 220 retracts into the detection seat 210. The lever 240 is rotatably mounted on the base 100, and one end of the lever 240 extends into the groove 110. The other end of 0 abuts against the bottom end of the marker post 220. The material loading assembly 300 includes a core post 310, a slide block 320, and a second elastic member 330. The core post 310 is disposed on the inner bottom wall of the slide groove 110. The slide block 320 is slidably disposed in the slide groove 110, and the core post 310 passes through the slide block 320. The second elastic member 330 abuts against the slide block 320 and the base 100 respectively. The second elastic member 330 is used to push the slide block 320 so that the top end of the slide block 320 extends from the top end of the core post 310. The core post 310 is used to support the adjustment structure 21. The slide block 320 is used to support the valve body 22. When the valve body 22 is pushed by force to lower the slide block 320 relative to the core post 310, the top end of the adjustment structure 21 extends from the top end of the valve body 22, and the material clamping member 400 is engaged with the slide block 320, and the valve body 22 abuts against the lever 240.

[0033] It should be noted that, in its natural state, the second elastic element 330 pushes the slide 320, causing the slide 320 to extend from the top of the core column 310. First, the adjusting structure 21 is placed on the top of the core column 310, then the washer 23 is fitted onto the adjusting structure 21, and then the valve body 22 is fitted onto the adjusting structure 21. Next, downward pressure is applied to the valve body 22; for example, a cylinder or other driving source can be used to apply pressure to the valve body 22. Since the core column 310 is fixedly installed relative to the base 100, the adjusting structure 21 remains stationary, and the valve body 22 pushes the slide 320 downward. During this process, the second elastic element 330 is compressed until the clamping element 400 clamps and fixes the slide 320. At this point, the top of the adjusting structure 21 will extend from the top of the valve body 22, indicating that the adjusting structure 21 and the valve body 22 are properly assembled. It is important to note that if gasket 23 is not missing, valve body 22 will not push lever 240 in this state, and therefore the marker post 220 will not be pushed by lever 240 to protrude from the top surface of detection seat 210. If gasket 23 is missing, valve body 22 will descend a greater distance than theoretically possible in this state; this greater descent is the thickness of the missing gasket 23. Because valve body 22 with missing gasket 23 descends a greater distance than valve body 22 with properly installed gasket 23, valve body 22 will push lever 240, causing lever 240 to push marker post 220. The first elastic element 230 is compressed, and marker post 220 will protrude from the top surface of detection seat 210. Therefore, by observing whether marker post 220 protrudes from the top surface of detection seat 210, it can be determined whether gasket 23 is missing. Furthermore, at this time, the slide block 320 is clamped and fixed by the retaining element 400, so that the adjusting structure 21 is stably maintained in the state of extending from the top surface of the valve body 22, and thus the retaining ring 24 can be assembled onto the adjusting structure 21. In one embodiment, both the first elastic element 230 and the second elastic element 330 are helical springs. In this way, the novel thermostatic valve core elastic retaining ring assembly device 10 of this application can quickly assemble the adjusting structure 21, valve body 22, washer 23, and retaining ring 24 into a thermostatic valve core component, and can effectively avoid the omission of washer 23.

[0034] like Figure 1 As shown, in one embodiment, when the top end of the slide 320 extends from the top end of the core column 310, the core column 310 and the slide 320 together form a material loading groove 301, and the adjustment structure 21 is adapted to be accommodated in the material loading groove 301.

[0035] It should be noted that in order to enable the adjustment structure 21 to be quickly loaded onto the core column 310, the second elastic element 330 pushes the slide block 320 out from the top of the core column 310 in its natural state, thereby forming a material loading groove 301 at the top of the core column 310, and the adjustment structure 21 can be placed directly in the material loading groove 301.

[0036] like Figure 1and Figure 4 As shown, in one embodiment, the outer side wall of the core post 310 is provided with a plurality of protruding ridges 311, and the inner side wall of the slide block 320 is provided with a plurality of grooves 321, with each protruding ridge 311 corresponding to and passing through each groove 321.

[0037] It should be noted that the protruding rib 311 is slidably connected to the groove 321. This allows the slide block 320 to slide stably along the axial direction of the core column 310, and also enables the groove 321 of the slide block 320 to position the adjusting structure 21. Specifically, a structure equivalent to the protruding rib 311 is provided on the outer wall of the adjusting structure 21. This allows the adjusting structure 21 to be positioned using the groove 321, enabling the adjusting structure 21 to be quickly and accurately fed into the material loading groove 301.

[0038] like Figure 2 , Figure 3 and Figure 5 As shown, in one embodiment, a locking hole 322 is provided on the slide 320 along the radial direction, and an inclined top surface 323 is provided between the bottom end of the slide 320 and the locking hole 322. When the valve body 22 is pushed by force to lower the slide 320 relative to the core column 310, the inclined top surface 323 pushes the locking member 400, thereby making the locking member 400 engage with the locking hole 322.

[0039] It should be noted that when the valve body 22 is subjected to force and descends, the slide 320 descends relative to the core column 310, the second elastic element 330 is compressed, and the adjusting structure 21 extends from the top surface of the valve body 22. To maintain this state, a locking hole 322 is provided radially on the slide 320, and an inclined top surface 323 is located between the locking hole 322 and the bottom end of the slide 320. Thus, when the slide 320 descends, the inclined top surface 323 pushes against the locking member 400, and finally the locking member 400 is inserted into the locking hole 322 to lock and fix the slide 320.

[0040] like Figures 2 to 4 As shown, in one embodiment, the core post 310 is provided with a locking step 312, which is used to lock the slide block 320. In this way, by using the locking step 312 to lock the slide block 320, the slide block 320 can be prevented from sliding off the core post 310.

[0041] like Figures 2 to 4 As shown, in one embodiment, a clearance groove 324 is also provided on the outer side wall of the slide block 320 along the axial direction, and one end of the lever 240 extending into the slide groove 110 is located in the clearance groove 324.

[0042] It should be noted that the clearance groove 324 provides clearance for the lever 240, thus preventing the slide 320 from pushing against the lever 240 when it descends relative to the core column 310.

[0043] like Figure 6 As shown, in one embodiment, the novel thermostatic valve core elastic retaining ring assembly device 10 further includes a pressure rod 510. A pressure block 520 is provided on one end of the pressure rod 510. A pressure groove 521 adapted to the retaining ring 24 is provided on the pressure block 520. When the pressure rod 510 is subjected to force, the pressure groove 521 pushes the retaining ring 24 to engage with the adjustment structure 21.

[0044] It should be noted that the above structure is designed to enable the retaining ring 24 to engage quickly and stably with the adjusting structure 21. Specifically, the operator holds the pressure rod 510 and places the retaining ring 24 in the pressure groove 521, which allows the retaining ring 24 to be stably and quickly engaged with the adjusting structure 21. In this way, the adjusting structure 21, valve body 22, gasket 23, and retaining ring 24 are assembled into a thermostatic valve core component.

[0045] like Figure 2 and Figure 3 As shown, in one embodiment, the detection assembly 200 further includes a guide sleeve 250, which is disposed on the detection seat 210, and the marker post 220 is adaptedly inserted into the guide sleeve 250. In this way, the smoothness of the sliding of the marker post 220 can be improved, that is, the marker post 220 can be stably slidably installed with the detection seat 210.

[0046] like Figure 2 and Figure 3 As shown, in one embodiment, the end of the marker post 220 that abuts against the lever 240 is configured as a spherical surface 221.

[0047] It should be noted that when the lever 240 is pressed down by the valve body 22, the lever 240 pushes against the spherical surface 221, thereby causing the marker post 220 to stably extend from the top surface of the detection seat 210. The contact part between the marker post 220 and the lever 240 is the spherical surface 221, which can reduce the friction between the marker post 220 and the lever 240.

[0048] In one embodiment, the clamping component 400 includes a clamping post, a clamping spring, and a clamping pin. The clamping post is disposed on the base 100, and the clamping pin is slidably disposed within the clamping post. The clamping spring abuts against both the clamping pin and the clamping post, and is used to push the clamping pin so that it extends into the slide groove 110. This allows the clamping pin to be inserted into the clamping hole 322 to clamp and fix the slide 320. When a reverse pulling force is applied to the clamping pin to compress the clamping spring, the clamping pin is pulled out of the clamping hole 322, at which point the second spring 330 can push the slide 320 back to its original position.

[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
