Description

Technical Field

[0001] The utility model relates to the technical field of heavy hammers, in particular to a heavy hammer. Background Art

[0002] The hose of the pull-out faucet usually needs to be equipped with a heavy hammer. When the shower head of the pull-out faucet is pulled out, the gravity of the heavy hammer can quickly reset the shower head.

[0003] The traditional weight is a one-piece or two-piece component made of metal material, and is provided with a hole for the hose to pass through, so that the weight can be installed on the hose. For cost considerations, the metal material used to make the weight is usually iron, which is easy to rust. For this reason, plastic is used to wrap the counterweight block made of iron in the subsequent product improvement to prevent rust. The corresponding production process is to put the counterweight block into the injection mold, and use the secondary injection molding process to form a shell on the surface of the counterweight block, in order to completely wrap the counterweight block and isolate the counterweight block from air and water vapor. However, due to the limitations of existing processes and product structures, such as the "integrated quick-loading weight" disclosed in patent CN204940431U, in order to completely wrap the counterweight block when injecting plastic, it is necessary to separate the counterweight block from the inner wall of the mold, that is, to provide a structure such as a pillar to support and suspend the counterweight block, and the structure such as the pillar will leave holes on the surface of the shell when demoulding, and it is not possible to achieve "full wrapping" in the true sense. In the process of product use, it is inevitable that water vapor penetrates into the holes and contacts with the counterweight block, causing the counterweight block to rust. Therefore, a subsequent process of sealing the holes is required, which makes the production process complicated and the cost higher, and there will also be appearance problems such as discontinuity and uneven color of the product surface.

[0040] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0041] refer to Figures 1 to 11 As shown, the utility model discloses a heavy hammer, comprising a hammer body 1, wherein the hammer body 1 comprises a counterweight block 11, a support member 12 and a housing 13;

[0042] The counterweight block 11 is fixedly installed with the support member 12, and is separated from the inner wall A of the injection mold by the support of the support member 12, so as to achieve the purpose of suspending the counterweight block 11;

[0043] The housing 13 is coated on the surface of the counterweight 11 through a secondary injection molding process and connected to the support 12. The housing 13 fully encapsulates the counterweight 11 through cooperation with the support 12, thereby isolating the counterweight 11 from the air.

[0044] There are two hammer bodies 1, namely a left hammer body 1a and a right hammer body 1b; the left hammer body 1a and the right hammer body 1b are respectively provided with a left mating surface 14 and a right mating surface 15, and the left mating surface 14 and the right mating surface 15 are respectively provided with a left groove 141 and a right groove 151, and the left groove 141 and the right groove 151 are matched to form a through hole for the hose to pass through.

[0045] See also Figure 7 Through the above scheme, the utility model can separate the counterweight block 11 from the inner wall A of the injection mold through the support member 12 during the secondary injection molding process by designing a support member 12 fixedly installed with the counterweight block 11. Therefore, after the material for encapsulating the counterweight block 11 is injected into the injection mold, the material can completely cover the surface other than the fitting part of the counterweight block 11 and the support member 12, and together with the support member 12, the counterweight block 11 can be fully wrapped. After the product is formed, the counterweight block 11 can be completely isolated from the air, and no other "hole sealing" treatment is required, thereby realizing rapid molding of the product, simple production process and high production efficiency.

[0046] Specific embodiments of the present utility model are shown below.

[0047] The above-mentioned support member 12 and shell 13 are made of the same material, such as plastic or plastic, so that the physical properties of the two are the same. The shell 13 formed by secondary injection molding is easier to be combined with the support member 12 into an integrated structure; the counterweight block 11 is made of metal material, such as iron, stainless steel, etc., or other high-density and low-cost materials.

[0048] The counterweight 11 is provided with a first positioning groove 111, and a first positioning column 121 is provided on one side of the support 12 for mounting the counterweight 11. The first positioning column 121 is embedded in the first positioning groove 111 to achieve relative fixation of the counterweight 11 on the support 12. The port of the first positioning groove 111 can be appropriately recessed to match the surface shape of the support 12.

[0049] Furthermore, a plurality of first ribs 122 are disposed on the side of the first positioning column 121 . When the first positioning column 121 is embedded in the first positioning groove 111 , the first ribs 122 are tightly fitted in the side wall of the first positioning groove 111 , so that the support member 12 and the counterweight block 11 can be combined more firmly.

[0050] At the same time, the bottom of the first positioning groove 111 penetrates through the surface of the counterweight 11 to form a through hole, so that the material constituting the shell 13 can penetrate into the first positioning groove 111, and the shell 13 and the counterweight 11 can be combined more firmly.

[0051] The support member 12 is fitted on the inner side surface of the counterweight 11 , that is, the support member 12 is located on the left mating surface 14 / the right mating surface 15 , and is provided with an arc groove 123 communicating with the left groove 141 / the right groove 151 .

[0052] Further, see Figure 4 , Figures 8 to 11The utility model also includes a gasket 2; the gasket 2 is installed in the arc groove 123 to increase the friction between the weight and the hose. Since there are many types of hoses that match the weight, the through hole formed by the left groove 141 and the right groove 151 sometimes cannot completely hold the hose, which may be displaced under the gravity of the weight and affect the function. After the product is formed, the gasket 2 can be installed on the support member 12 to increase the friction between the weight and the hose, thereby playing an anti-slip role. Among them, see Figure 8 , which is the first embodiment of the gasket 2, which is made of soft materials, such as rubber, silicone, etc. When the heavy hammer hugs the hose, the gasket 2 is squeezed and deformed to provide friction; see Fig. 9 , which is a second embodiment of the gasket 2, which is made of hard material, such as plastic, metal, etc., and the inner side of the gasket 2 is provided with a plurality of convex particles 21. When the weight holds the hose, the convex particles 21 abut against the surface of the hose to provide friction; see Fig.10 , which is a third embodiment of the gasket 2, which is made of hard material, such as plastic, metal, etc., and the inner side of the gasket 2 is provided with a plurality of circumferential flanges 22. When the weight holds the hose, the circumferential flanges 22 abut against the surface of the hose to provide friction; see Fig.11 , which is the fourth embodiment of the gasket 2, which is made of hard material, such as plastic, metal, etc., and the inner side of the gasket 2 is provided with a plurality of threads 23. When the weight holds the hose, the threads 23 abut against the surface of the hose to provide friction. The type of the gasket 2 can be selected according to actual needs, and it is very convenient to replace.

[0053] At the same time, a second positioning groove 124 is provided in the arc groove 123, and a second positioning column 24 is provided on the side of the gasket 2 facing the support member 12. The second positioning column 24 is embedded in the second positioning groove 124 to achieve relative fixation of the gasket 2 on the support member 12. In this embodiment, a plurality of second ribs 25 are provided on the side of the second positioning column 24. When the second positioning column 24 is embedded in the second positioning groove 124, the second ribs 25 are tightly fitted in the side wall of the second positioning groove 124, so that the gasket 2 and the support member 12 can be combined more firmly; at the same time, see Figure 7 The second positioning groove 124 of the support member 12 can also cooperate with the limiting column B in the mold to realize the positioning of the support member 12 when placing the support member 12 and the counterweight block 11 to prevent shaking. The port of the second positioning groove 124 can be appropriately recessed to match the surface shape of the gasket 2.

[0054] Both ends of the support member 12 extend axially to form an extension portion 125 , and the extension portion 125 is covered by the shell 13 , so as to realize the positioning of the support member 12 in the shell 13 and prevent the support member 12 from loosening and shaking.

[0055] One side of the left hammer 1a is fixedly connected to one side of the right hammer 1b via a connecting piece 16, and the connecting piece 16 is integrally formed with the shell 13 of the left hammer 1a / right hammer 1b; the other side of the left hammer 1a is fastened to the other side of the right hammer 1b via a locking buckle 17, so that the heavy hammer can be tightly held on the hose.

[0056] Furthermore, the lock buckle 17 includes a buckle 171 and a buckle groove 172 that cooperate with each other. In this embodiment, the buckle 171 and the buckle groove 172 are respectively arranged on the other side of the housing 13 of the left hammer body 1a and the right hammer body 1b relative to the connecting piece 16. In this embodiment, the hook portion of the buckle 171 is arranged outwardly on the surface facing away from the weight, and the buckle groove 172 is a through hole arranged on the surface of the weight. The buckle 171 passes through the buckle groove 172 and hooks on the side wall of the buckle groove 172 to achieve fastening. When the user needs to disassemble the weight, he only needs to press the buckle 171 inward to make the buckle 171 detach from the side wall of the buckle groove 172 so as to open the left hammer body 1a and the right hammer body 1b, which is easier to operate, especially when the space under the basin in the kitchen or bathroom is limited.

[0057] Secondly, both sides of the shell 13 are recessed to form a clearance groove 131, and the connecting piece 16, the buckle 171, and the buckle groove 172 are respectively integrally formed in the corresponding clearance groove 131, so that the connecting piece 16, the buckle 171, and the buckle groove 172 do not protrude from the outer peripheral surface of the shell 13 when the weight is in the engaged state, which can reduce the interference caused by the contact with other objects under the basin during the lifting and lowering movement of the weight.

[0058] At the same time, both sides of the housing 13 are provided with limiting mechanisms, which include a convex portion 132 and a concave portion 133 that match each other; when the lock buckle 17 is fastened, the convex portion 132 is embedded in the corresponding concave portion 133. By providing multiple sets of limiting mechanisms, the left hammer body 1a and the right hammer body 1b will not shake in the front, back, left, and right directions after being matched.

[0059] Both ends of the housing 13 are provided with inclined guide surfaces 134 . If the weight hits other objects during movement, the weight can be displaced relative to other objects by the inclined guide surfaces 134 , thereby reducing interference with other objects.

[0060] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
