Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to valve components. Background Art

[0002] At present, for a type of valve on the market, a rope is used to connect the valve body and the valve cover to prevent the valve cover from being lost. In this way, when the valve cover is removed from the valve body, the valve cover is still connected to the valve body by the rope, thus preventing the valve cover from being lost.

[0003] Among them, the current connection method is to pass the rope through the valve body and the valve cover respectively, and then tie knots at both ends of the rope to form a knot, which can form a limit to prevent the rope from detaching.

[0004] This process can only be completed manually, and obviously has a low operation efficiency.

[0005] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present utility model, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0011] The through hole includes a channel and a second counter bore. The channel is configured to allow the second injection molding part to pass through, and the second injection molding part is configured to be stuck in the second counter bore.

[0012] In some embodiments, the channel and the second counter bore are juxtaposed and connected by a truncated pore. The truncated pore is configured such that after the second injection molding part passes out of the channel, the rope is translated from the truncated pore to the second counter bore.

[0013] In some embodiments, the aperture of the channel is larger than the aperture of the second counter bore.

[0014] In some embodiments, the second counter bore has a wire inlet and a wire outlet for the second injection molded part to enter. Along the direction from the wire inlet to the wire outlet, the second counter bore includes a clamping groove adapted to clamp the second injection molded part and a duct communicating with the clamping groove, and the duct is configured to allow the rope to pass through.

[0015] In some embodiments, the second injection molded part is strip-shaped.

[0016] In some embodiments, both ends of the second injection molded part are tapered or truncated-conical.

[0017] In some embodiments, the first injection molded part is spherical.

[0018] In some embodiments, the first counter bore is formed in the valve body, and the first injection molded part is located inside the first counter bore along the central axis of the valve body.

[0019] In some embodiments, a screwing operation part is provided at the top of the valve cover, and the through hole is provided in the screwing operation part.

[0032] An embodiment of the present disclosure provides a valve assembly, as Figure 1 and 2 shown, which includes:

[0033] A valve body 1, a valve cover 2 and a rope 3. First injection molded parts 31 ( Figure 1 not shown) and second injection molded parts 32 are respectively provided at both ends of the rope 3;

[0034] A first counter bore 4a and a through hole 4b are respectively provided in the valve body 1 and the valve cover 2. Exemplarily, the first counter bore 4a is provided in the valve body 1 and the through hole 4b is provided in the valve cover 2;

[0035] The first injection molded part 31 is stuck in the first counter bore 4a;

[0036] The through hole 4b includes a channel 4b1 and a second counter bore 4b2. The channel 4b1 is configured to allow the second injection molded part 32 to pass through, and the second injection molded part 32 is configured to be stuck in the second counter bore 4b2 after passing through the channel 4b1.

[0037] During the assembly process, the second injection molded part 32 is made to pass through the first counter bore 4a and the channel 4b1 in sequence, and after passing through the channel 4b1, it is stuck in the second counter bore 4b2, while the first injection molded part 31 is left in the first counter bore 4a and stuck in the first counter bore 4a. In this way, both ends of the rope 3 are stuck in the corresponding counter bores through the injection molded parts, avoiding detachment, so as to connect the valve cover 2 and the valve body 1.

[0038] Compared with the knotting process of the prior art, the injection molded parts at both ends of the rope 3 in this embodiment are injection molded, and the rope 3 is a batch-produced finished part. During the assembly process, there is no need for a relatively complex process such as knotting, the assembly process has high efficiency, and it is easier to achieve automatic assembly. The valve assembly of this embodiment has high assembly efficiency.

[0039] As Figure 2 shown, the first counter bore 4a is provided in the valve body 1 and the through hole 4b is provided in the valve cover 2. In another embodiment, a through hole can be provided in the valve body and a first counter bore can be provided in the valve cover. The specific layout form of the first counter bore and the through hole can be selected according to the shape of the valve, and no limitation is made here.

[0040] As Figure 2 shown, the first injection molded part 31 is located inside the first counter bore 4a along the central axis of the valve body 1. Here, the inside refers to the side located inside the functional device when the valve body 1 is installed on the functional device.

[0041] In this embodiment, asFigure 2 As shown, the first injection molded part 31 is spherical and can be clamped more tightly within the first counter bore 4a. The first counter bore 4a can be a ball socket or a slotted hole. In one embodiment, the first counter bore 4a can also be a tapered hole with both ends open. The larger opening of the tapered hole serves as the entrance for the second plastic part 32, and the smaller opening serves as the exit for the second plastic part 32. Moreover, the first plastic part 31 also enters through the larger opening and is blocked by the smaller opening, thereby being clamped within the first counter bore 4a.

[0042] In the embodiments of the present disclosure, as Figure 1 and 2 shown, the channel 4b1 is juxtaposed with the second counter bore 4b2 and is connected through a truncated pore 4b3. The truncated pore 4b3 is configured such that after the second injection molded part 32 exits from the channel 4b1, the cord 3 is translated from the truncated pore 4b3 to the second counter bore 4b2. The second injection molded part 32 is made to exit upward from the channel 4b1, then the cord 3 is translated to the adjacent second counter bore 4b2, and then the cord 3 is pulled downward to clamp the second injection molded part 32 within the second counter bore 4b2.

[0043] In this embodiment, the aperture of the channel 4b1 is larger than the aperture of the second counter bore 4b2. In this way, the second injection molded part 32 can be smoothly exited from the channel 4b1 and can be tightly clamped within the second counter bore 4b2 with a smaller aperture.

[0044] In this embodiment, as Figure 2 shown, the second counter bore 4b2 has a wire inlet 4b21 and a wire outlet 4b22 for the second injection molded part 32 to enter. Along the direction L from the wire inlet 4b21 to the wire outlet 4b22, the second counter bore 4b2 includes a card slot 4b23 adapted to clamp the second injection molded part 32 and a pore 4b24 connected to the card slot 4b23. The pore 4b24 is configured to allow the cord 3 to exit.

[0045] In this embodiment, the second injection molded part 32 exits from the channel 4b1 as a whole, the cord 3 is translated into the second counter bore 4b2, and then the cord 3 is pulled backward so that the second injection molded part 32 enters the card slot 4b23 from the wire inlet 4b21. The card slot 4b23 is used to clamp the second injection molded part 32, and the cord 3 is led out from the pore 4b24, that is, led out from the wire outlet 4b22.

[0046] Among them, the shape of the card slot 4b23 can also refer to the first counter bore 4a above, which is not limited herein.

[0047] In another embodiment, the position between the channel and the second counterbore can also be such that the center line of the through hole is perpendicular to the center line of the second counterbore or forms another angle greater than 0. In this way, one end of the second counterbore communicates with the wire outlet of the channel, and a lateral truncation pore is formed in the side wall of the second counterbore, allowing the rope to enter the second counterbore horizontally.

[0048] In the embodiments of the present disclosure, as Figure 2 shown, the second injection-molded part 32 is strip-shaped, which is convenient for clamping or grasping during its assembly process.

[0049] In the embodiments of the present disclosure, both ends of the second injection-molded part 32 are tapered or truncated-conical, so that it is easier to enter and exit the channel 4b1 and enter the card slot 4b23.

[0050] As Figure 1 and 2 shown, a screwing operation part 21 is provided at the top of the valve cover 2, and the through hole 4b is provided in the screwing operation part 21. The screwing operation part 21 has a certain installation space for making the through hole 4b.

[0051] Optionally, as Figure 1 shown, the center line of the through hole 4b is perpendicular to the center line of the valve cover 2, and the through hole 4b penetrates through the two side walls 210 of the screwing operation part 21. The distance between the two side walls here is less than the distance between the two end side walls of the screwing operation part 21.

[0052] This can relatively reduce the length of the through hole 4b and reduce the manufacturing difficulty and assembly difficulty.

[0053] In addition, the valve assembly of the embodiments of the present disclosure can be used for an inflation valve, such as for products such as surfboards, tents, inflatable boats, inflatable yoga mats, etc.

[0054] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present invention.
