Description

Valve core ring-type clamping device with circumferential clamping effect

This invention relates to a local structure of a valve core, and in particular to an innovative structural form of a valve core ring-type locking device with a circumferential locking effect.

Faucet valve cores are generally divided into two types in terms of their actuation modes: fixed-axis rotary and swing-type. This invention mainly aims to improve and break through the fixed-axis rotary structure.

The known fixed-axis rotary valve core structure design usually has the function of segmented positioning of the brake shaft rotation. The interlocking positioning part is usually formed directly on a linkage plate driven by the bottom end of the brake shaft and its corresponding valve housing structure in a slightly protruding shape, and then the elastic toughness of the plastic is used to produce the interlocking positioning effect. However, this known structure is still found to have some problems in actual use experience. For example: because of its interlocking The card positioning portion is directly formed in a protruding shape on the linkage plate and its corresponding valve housing structure, so the embedded card positioning portion is easily quickly worn and damaged due to repeated relative movements, resulting in a short service life of the embedded card positioning portion and a lack of durability and practicality. Therefore, the directly formed one-piece embedded card positioning portion cannot partially replace components or needs to form the valve housing with two materials, which obviously will cause a problem of significantly increased costs.

The main purpose of this invention is to provide a valve core ring-type clamping device with a circumferential clamping effect. The technical problem it aims to solve is how to develop a new type of clamping device structure that is more ideal and practical to make innovative breakthroughs.

Based on the above-mentioned purpose, the present invention provides a valve core annular clamping device with a circumferential clamping effect. The annular clamping device is arranged between a circular frame formed at the upper end of a valve shell provided on the valve core and a valve rod driven seat in a radial configuration, wherein the circular frame has a frame opening, the valve rod driven seat is rotatably arranged in the circular frame, and the valve rod driven seat forms a valve rod through-opening and a rotating seat portion; the annular clamping device includes: at least one elastic clamping portion formed around the rotating seat portion of the valve rod driven seat, the elastic clamping portion includes an arched elastic The invention discloses a circular frame body comprising a circular frame body and a radial flange formed on the outer side of the arched elastic arm; a C-shaped card holder is assembled in the circular frame body, and the C-shaped card holder includes an inner side, an outer side and a compression notch, wherein a convex portion is formed on the inner side, and the convex portion must be located on the rotation path of the elastic card moving portion; a plurality of wing grooves are formed in a local section of the circular frame body and are in a relatively large radial depth; a plurality of wing pieces are formed in a local section of the outer side of the C-shaped card holder, and the wing pieces are aligned and embedded in the wing grooves, so that the C-shaped card holder can obtain a positioning and anti-rotation effect.

With this innovative structural form and technical features, compared with previous technologies, the C-shaped card holder that achieves the card function is a combined detachable component, so it can be quickly replaced to maintain its normal function; it can also be matched with different weather-resistant materials according to different usage environments, thereby achieving advantages and practical progress in use and manufacturing.

Please refer to Figures 1 to 5, which are preferred embodiments of the valve core ring-type clamping device with a circumferential clamping effect of the present invention. However, these embodiments are for illustrative purposes only and are not limited to this structure in patent applications.

The annular clamping device is arranged between a circular frame 11 formed at the upper end of a valve housing 10 provided with a valve core and a valve rod driven seat 20 in a radial configuration, wherein the circular frame 11 has a frame opening 12, and the valve rod driven seat 20 is rotatably arranged in the circular frame 11, and the valve rod driven seat 20 is formed with a valve rod through-opening 21 and a rotating seat portion 22; the annular clamping device includes: at least one elastic clamping portion 30 formed around the rotating seat portion 22 of the valve rod driven seat 20, and the elastic clamping portion 30 includes an arched elastic arm 31 and a radially convex protrusion formed on the outer side of the arched elastic arm 31. The circular frame 11 includes a C-shaped card holder 40, which is assembled in the circular frame 11. The C-shaped card holder 40 includes an inner side 41, an outer side 42 and a compression notch 43, wherein the inner side 41 is formed with a protrusion 44, and the protrusion 44 must be located on the rotation path of the elastic card portion 30; a plurality of wing grooves 50 are formed in a local section of the circular frame 11 and are relatively deep in the radial direction; a plurality of wing pieces 60 are formed in a local section of the outer side 42 of the C-shaped card holder 40, and the wing pieces 60 are aligned and embedded in the wing grooves 50, so that the C-shaped card holder 40 can obtain a positioning and anti-rotation effect.

Based on the above-mentioned structural assembly form and technical features, the use and operation of this invention are explained as follows: As shown in Figures 4 and 6, the elastic clamping part 30 can change its angle as the rotating seat part 22 of the valve rod drives the seat 20. When the radial flange 32 of the elastic clamping part 30 passes over the protrusion 44 of the C-shaped clamping frame 40 as shown in Figure 6, the user can feel an obvious clamping over-blocking (or over-embedded) feeling during operation, thereby providing a prompt to the user (for example, the flow channel has switched to another flow direction). Since the C-shaped card holder 40 used in the invention to achieve the card function is a combined detachable component, it can be quickly replaced to maintain its normal function; from another perspective, it can be matched with different weather-resistant materials in response to different usage environments, thereby achieving advantages in use and manufacturing and practical progress.

As shown in FIG. 2 , in this example, the outer side 42 of the C-shaped card holder 40 is divided into left and right sides by the compression notch 43, wherein the left and right sides are respectively formed with two wing pieces 60, a notch 61 is formed between the two wing pieces 60, and the two wing pieces 60 are respectively formed with a front wing side 62 and a rear wing side 63 on the opposite sides away from each other, and the left and right sides of the circular frame 11 are respectively formed with two long wing grooves 50, so that the two wing pieces 60 formed on the left and right sides are respectively embedded in the long wing grooves 50. When the disclosed type in this example is assembled, the notch 61 can prevent the C-shaped card holder 40 from slipping when it is compressed.

As shown in FIG. 7 , in this example, the front wing side 62B, the rear wing side 63B and the corresponding groove wall of the long wing groove 50B are not parallel, and the front wing side 62B and the rear wing side 63B are of a type with relatively reduced width at the outer ends. The advantage of this type is that there is no interference during assembly, but after installation, the transition of the circumferential dimension can be used to eliminate the dimensional error and avoid the shaking problem.

As shown in FIG. 2 , in this example, a ring-shaped limiting edge 13 is formed on the circular frame 11 structure at a position corresponding to the elastic clamping portion 30 for the C-shaped clamping frame 40 to abut against and limit.

As shown in FIG. 5 , the C-shaped card holder 40 is defined to form a contraction direction L1 according to the opening position of the contraction notch 43, so that the wing pieces 60 and the wing grooves 50 are both protruded along the contraction direction L1 (i.e., they are close to a parallel relationship). In this way, when the C-shaped card holder 40 is inserted or removed, the wing pieces 60 and the wing grooves 50 are inserted or released along the contraction direction L1, thereby achieving the advantage of smoother and more convenient assembly and disassembly.
