Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, in particular to a detachable hose wrench. Background Art

[0002] Hexagonal nuts are a common method of securing bathroom fixtures. For example, stainless steel braided hoses are fitted with nuts at both ends. During installation, a wrench is used to twist the nuts so that the threads on the nuts engage with the threads on the water inlet or outlet. However, wrenches are not commonly found in households. Therefore, to facilitate user installation, existing hoses are often fitted with a plastic wrench. This wrench is ring-shaped and has two protruding wrench sections along its outer wall. During use, the plastic wrench is inserted into the nut, aligning the hexagonal shape of the wrench's inner wall with the nut. Force is applied to the wrench sections to install the nut. However, after installation, the plastic wrench is blocked by the ends of the hose, allowing only movement within the hose and preventing removal. Therefore, existing plastic wrenches cannot be reused. If the user needs to remove the wrench after installation for aesthetic reasons, they must destroy it, such as by cutting it. To ensure sufficient strength, plastic wrenches are constructed to be thin, making removal difficult and resulting in a poor user experience. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0035] Combine Figures 1 to 16 The present embodiment provides a detachable hose wrench, comprising an integrally formed wrench body 1, wherein the wrench body 1 is annularly arranged and has an opening 11 for the hose to enter and exit, and a locking structure for controlling the opening 11 is formed or assembled on the opening 11. When the opening 11 is closed, the inner wall of the wrench body 1 forms an inner hexagonal jaw 12 for adapting to the nut, and at least one operating portion 13 is formed on the outer wall of the wrench body 1. The operating portion 13 is driven in an operative manner to cause the wrench body 1 to drive the nut to rotate synchronously.

[0036] Exemplarily, the wrench body 1 is integrally injection molded using a plastic material. When in use, force is applied to the opening 11 against the side of the hose so that the hose stretches the opening 11 to be inserted into the wrench body 1, and then the opening 11 is closed by the locking structure. At this time, a hexagonal jaw 12 is formed on the inner wall of the wrench body 1. Move along the hose to the nut, insert the hexagonal jaw 12 into the nut, and then apply force to the operating part 13 to make the wrench body 1 drive the nut to rotate synchronously, thereby realizing the disassembly and assembly of the nut. When removing the wrench, only the locking structure needs to be unlocked, and then force is applied to the wrench body 1, and the wrench can be pulled out of the hose along the opening 11, realizing the removal of the wrench, which is convenient and quick. Preferably, a stop portion 14 can also be provided on the inner wall of the wrench body 1 to prevent the nut from slipping out of the hexagonal jaw 12.

[0037] It should be noted that in this embodiment, an opening 11 and a locking structure for controlling the opening and closing of the opening 11 are provided on the wrench body 1 to achieve the disassembly and assembly of the wrench, which is convenient for users to disassemble and reuse without damaging the structure of the wrench, thereby improving the user experience.

[0038] In a preferred embodiment, both sides of the opening 11 are extended outward so that when the opening 11 is closed, a lug 2 is formed for cooperating with the operating portion 13 to rotate the wrench body 1. In one embodiment, the opening 11 is provided on the opposite side of the operating portion 13 so that the lug 2 and the operating portion 13 are arranged in a straight line, thereby facilitating user operation. In another embodiment, two operating portions 13 may also be provided, and the lug 2 is provided between the two operating portions 13. The user places his hand on the two operating portions 13 to rotate the wrench body 1. The lug 2 is provided between the two operating portions 13 so that the position directly opposite the opening 11 is the position of the non-operating portion 13, thereby ensuring the elastic deformation ability of this position, which is conducive to the opening of the opening 11 and facilitates user operation.

[0039] Based on the above embodiment, in an optional embodiment of the present invention, the locking structure includes a first locking portion 31 formed on one side of the opening 11, and a second locking portion 32 formed on the other side of the opening 11. The first locking portion 31 and the second locking portion 32 engage and limit each other to close the opening 11. The locking structure is integrally formed with the wrench body 1, which can reduce the assembly of parts and the cost of mold making. It can also prevent the loss of parts during the disassembly and assembly of the wrench, making it easier for users to reuse it. It includes the following embodiments:

[0040] Method 1: Reference Figures 1 to 3The first retaining portion 31 has a mounting groove 311 with one end open, and the second retaining portion 32 has a first protrusion 321 with a T-shaped cross-section. The small end of the first protrusion 321 can be inserted along the opening of the mounting groove 311 so that the large end of the first protrusion 321 abuts against the outer wall of the mounting groove 311 to limit the position. For example, the mounting groove 311 is U-shaped. After the wrench body 1 is inserted into the hose along the opening 11, the wrench body 1 is pressed to offset the mounting groove 311 and the first protrusion 321 front-to-back. Then, the first protrusion 321 is inserted along the mounting groove 311 so that the large end of the first protrusion 321 abuts against the outer wall of the mounting groove 311, thereby limiting the position of the first retaining portion 31 and the second retaining portion 32 in the circumferential direction. When the wrench body 1 is rotated, the first protrusion 321 will not fall out. When the wrench needs to be removed from the hose, the wrench body 1 is pressed to slightly deform it, causing the first protrusion 321 to slide out of the opening of the assembly groove 311, thereby opening the opening 11. It should be noted that since the wrench body 1 is made of plastic, after the applied pressure is released, the wrench body 1 can rebound to its original state under the action of its own elastic force.

[0041] Method 2: Reference Figures 4 to 7 The first clamping portion 31 is configured as a slot 312, with a clamping surface 3121 formed in the slot 312, and the second clamping portion 32 is configured as a buckle 322, which is inserted into the slot 312 and abuts against the clamping surface 3121. The connection between the buckle 322 and the slot 312 is simple to assemble and disassemble, and can be fastened when locked. When dismantling, the second clamping portion 32 can be pressed toward the side away from the clamping surface 3121 to make the second clamping portion 32 fall out of the slot 312. The clamping surface 3121 can be located near the side of the wrench body 1, or away from the side of the wrench body 1, without being specifically limited. In this embodiment, the arrangement of the buckle 322 and the slot 312 can ensure that the first clamping portion 31 and the second clamping portion 32 are locked, thereby ensuring the connection strength of the two clamping portions.

[0042] In another preferred embodiment, the locking structure includes a first assembly portion 41 provided on one side of the opening 11, a second assembly portion 42 provided on the other side of the opening 11, and a locking member 43 for connecting the first assembly portion 41 and the second assembly portion 42. The addition of the locking member 43 further ensures the stability of the locking structure and the strength of the wrench during use. The following embodiments are included:

[0043] Method 1: Reference Figures 8 to 10A second boss 411 with a T-shaped cross-section is formed on the first assembly portion 41, and a mounting hole 421 is provided on the second assembly portion 42. The second boss 411 extends through the mounting hole 421, and a locking member 43 is inserted between the larger end of the second boss 411 and the second assembly portion 42 to retain the second boss 411 in position. For example, a U-shaped groove is provided on the locking member 43. The second boss 411 is inserted along the mounting hole 421, exposed on the other side of the second assembly portion 42. The U-shaped groove of the locking member 43 is then inserted between the larger end of the second boss 411 and the outer wall of the second assembly portion 42 to engage with the smaller end of the second boss 411, thereby retaining the second boss 411 in position and locking the corresponding first assembly portion 41 and second assembly portion 42. The opening 11 is closed. During disassembly, the locking member 43 can be removed to open the opening 11.

[0044] Method 2: Reference Figures 11 to 14 Both the first assembly portion 41 and the second assembly portion 42 are provided with an assembly hole 412, each with a stop surface 4121 defined therein. The locking member 43 is configured to be inserted along the assembly hole 412 and rotated until it abuts against the stop surface 4121. For example, one end of the locking member 43 is in the form of an elongated strip. After insertion into the assembly hole 412, the other end of the locking member 43 is rotated to rotate the elongated strip from a vertical orientation to a horizontal orientation, where it abuts against the stop surface 4121, thereby locking the first assembly portion 41 and the second assembly portion 42. During disassembly, the locking member 43 is rotated to rotate the elongated strip to a vertical orientation and then removed from the assembly hole 412, making assembly and disassembly convenient.

[0045] Method 3: Reference Figure 15 and Figure 16 The first assembly portion 41 and the second assembly portion 42 are both provided with threaded holes 413, and the locking member 43 is provided with threads adapted to fit within the threaded holes 413. Furthermore, the locking member 43 has a handle portion 431 arranged in a straight line. The handle portion 431 is located at the other end of the threaded portion. By rotating the handle portion 431, the threaded portion rotates, thereby locking and unlocking the first assembly portion 41 and the second assembly portion 42, and correspondingly controlling the opening and closing of the opening 11.

[0046] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.
