Description

Technical Field

[0001] The utility model belongs to the technical field of sprayer accessories and relates to a clamp for a sprayer. Background Art

[0002] At present, the liquid outlet of a sprayer barrel is connected to a spray rod through a hose, and a clamp is arranged at the connection between the two for fixation. A clamp is a commonly used connecting device. For example, a Chinese patent document discloses a clamp (application number: 201220560208.5), which includes at least two clamp bodies. The clamp bodies are connected by bolts. A rubber sealing ring is arranged inside the clamp bodies, and plastic coating layers are arranged on both the inner wall and the outer wall of the clamp bodies.

[0003] The following deficiencies exist in the use of this clamp: when the diameter of the hose is relatively large, after the two clamp bodies are connected by bolts, the ends of the two clamp bodies cannot abut against each other, so that the part of the hose between the ends of the two clamp bodies cannot be tightly clamped by the clamp on the liquid outlet of the barrel, making it easy for leakage to occur at this part; when the diameter of the hose is relatively small, after the ends of the two clamp bodies abut against each other, the two clamp bodies cannot get closer to each other further, resulting in a poor fastening effect of the clamp and causing water seepage after the hose is connected to the liquid outlet of the barrel. Summary of the Invention

[0004] The purpose of the utility model is to provide a clamp for a sprayer in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the reliability of the connection of the clamp.

[0005] The purpose of the utility model can be achieved by the following technical solutions:

[0006] A clamp for a sprayer includes a clamp body with a notch. Positioning parts are respectively arranged at positions on both sides of the notch of the clamp body. The two positioning parts are connected by screws. It is characterized in that a pressing part extending towards the other positioning part is further arranged on one of the positioning parts of the clamp body. The pressing part and the clamp body overlap inside and outside, and the inner walls of both the pressing part and the clamp body are arc-shaped and are smoothly and transitionally connected.

[0007] When in use, the user first sleeved the clamp body on the hose, and then fastened and connected the two positioning parts through screws. After the operation is completed, the outer side of the pressing part abuts against the clamp body, and the two jointly form an annular structure surrounding the hose. Since the pressing part and the clamp body are arranged overlapping inside and outside, by adjusting the size of the annular structure, the hose clamp for this sprayer can adapt to hoses of different sizes. In addition, the inner walls of both the pressing part and the clamp body are arc-shaped and are smoothly transitionally connected. The hose clamp for this sprayer forms a 360° surrounding closed loop on the outer peripheral side of the hose, can fasten the hose on the liquid outlet of the barrel body, can avoid leakage at the connection between the two, and thus improve the reliability of the clamp connection.

[0008] In the above-mentioned hose clamp for a sprayer, one end of the pressing part is integrally formed with the clamp body, and the other end is a free end in a narrowed shape. An arc-shaped section is provided on the outer wall of the free end of the pressing part, and the arc-shaped section can be in contact with the inner wall of the clamp body. By setting the free end of the pressing part in a narrowed shape, it is easier to undergo elastic deformation, so that the pressing part and the clamp body can better form a 360° surrounding annular closed-loop structure around the hose. In addition, an arc-shaped section is provided on the outer wall of the free end of the pressing part, so that the outer side of the pressing part can better abut against the clamp body, and at the same time, the inner side of the pressing part can better abut against the outside of the hose, thereby further improving the fastening of the connection between the hose and the liquid outlet of the barrel body, avoiding leakage at the connection, and further improving the reliability of the clamp connection.

[0009] In the above-mentioned hose clamp for a sprayer, a positioning through hole is provided on one positioning part, and a positioning blind hole is provided on the other positioning part. The positioning blind hole is arranged opposite to the positioning through hole, and the positioning blind hole has an internal thread. The above structure can, on the one hand, eliminate the nut, and on the other hand, it can also facilitate the user's operation of disassembling and assembling the screw.

[0010] In the above-mentioned hose clamp for a sprayer, the clamp body, the positioning part and the pressing part are integrally injection-molded. Injection molding can, on the one hand, reduce the manufacturing and use costs of the clamp, and on the other hand, has the effect of waterproofing and anti-oxidation, avoiding the clamp from rusting during use.

[0011] Compared with the prior art, the advantages of the hose clamp for this sprayer are as follows: By arranging the pressing part and the clamp body overlapping inside and outside, the hose clamp for this sprayer can adapt to hoses of different sizes. In addition, the inner walls of both the pressing part and the clamp body are arc-shaped and are smoothly transitionally connected, so that the hose clamp for this sprayer forms a 360° surrounding closed loop on the outer peripheral side of the hose, can fasten the hose on the liquid outlet of the barrel body, can avoid leakage at the connection between the two, and thus improve the reliability of the clamp connection.
