Technical Field

[0001] This utility model relates to the technical field of oil and gas pipeline maintenance tools, and in particular to a socket wrench. Background Technology

[0002] Replacing the filter element in the gasoline pipeline requires extensive disassembly and assembly. In particular, when removing the filter element bracket and filter element nuts, the screws are long, numerous, and the nuts are multi-layered, so using a regular wrench is time-consuming and labor-intensive.

[0003] Existing wrenches not only require a lot of time to operate, but also involve high labor intensity. The rows of screw wrenches are also inconvenient to use. Personnel are exposed to harmful gases and dust for a long time, and every minute the equipment is turned on increases the danger. Utility Model Content

[0004] The purpose of this utility model is to provide a socket wrench that can effectively improve work efficiency and reduce filter element exposure time.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Socket wrenches, including:

[0007] The sleeve body is configured as a locking and unlocking bolt structure;

[0008] A cross-shaped support has two first ends spaced apart along a first direction and two second ends spaced apart along a second direction, and the sleeve body is connected to one of the first ends of the cross-shaped support.

[0012] Preferably, the balance handle can be locked at the second end, and the balance handle has an extended state, a avoidance state, and a retracted state;

[0013] In the unfolded state, the balance handle extends along the second direction;

[0014] In the avoidance state, the balance handle is set at an acute angle relative to the positioning handle;

[0015] In the retracted state, the balance handle extends along the first direction.

[0016] Preferably, the balance handle includes:

[0017] The first connecting rod is rotatably connected at one end to the second end of the cross bracket;

[0018] The first grip portion is sleeved on the other end of the first connecting rod away from the cross bracket, and the first grip portion is provided with an anti-slip structure.

[0019] Preferably, the positioning handle includes a second connecting rod extending along the first direction, with one end rotatably connected to the first end of the cross bracket, and the second connecting rod is rotatable about the first direction.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1-3 As shown, this utility model provides a socket wrench for installing and removing bolt structures when replacing the filter element of a gasoline pipeline. The socket wrench includes a socket body 1, a cross bracket 2, a positioning handle 3, and two balance handles 4. The socket body 1 is configured to lock and unlock the bolt structure; the cross bracket 2 has two first ends spaced apart along a first direction and two second ends spaced apart along a second direction, with the socket body 1 connected to one of the first ends; the positioning handle 3 is connected to the other first end; the two balance handles 4 are rod-shaped and rotatably mounted on the two second ends of the cross bracket 2, with the angle between the axis of the balance handle 4 and the axis of the positioning handle 3 adjustable; the first direction is perpendicular to the second direction.

[0039] When installing or disassembling the bolt structure, the sleeve body 1 can be first placed on the bolt structure. The construction worker can press the positioning handle 3 with one hand to prevent the sleeve body 1 from slipping off; the other hand can rotate the balance handle 4, thereby driving the sleeve body 1 to rotate around the first direction through the cross bracket 2 to lock or unlock the bolt structure, which is highly efficient. When the spiral structure is in a narrow space, the balance handle 4 can be rotated around the second end of the cross bracket 2 to bring the balance handle 4 close to the positioning handle 3, so as to avoid the balance handle 4 from interfering with other objects during operation. It is highly versatile, highly flexible in operation, and has low manufacturing cost, making it easy to obtain materials on-site.

[0040] Specifically, the balance handle 4 can be locked to the second end of the cross bracket 2. The balance handle 4 has an extended state, a clearance state, and a retracted state. In the extended state, the balance handle 4 extends along a second direction. In the clearance state, the balance handle 4 is set at an acute angle relative to the positioning handle 3. In the retracted state, the balance handle 4 extends along a first direction. With the above configuration, when it is necessary to install or remove the bolt structure, the balance handle 4 can be locked in the extended state to facilitate the operator's rotation. When it is necessary to install or remove the bolt structure in a narrow space, the balance handle 4 can be locked in the clearance state to prevent the balance handle 4 from interfering with other objects during rotation. When it is necessary to store the socket wrench, the balance handle 4 can be locked in the retracted state to save storage space.

[0041] Specifically, the balance handle 4 includes a first connecting rod 41 and a first grip portion 42. One end of the first connecting rod 41 is rotatably connected to the second end of the cross bracket 2; the first grip portion 42 is fitted onto the other end of the first connecting rod 41 away from the cross bracket 2, and the first grip portion 42 is provided with an anti-slip structure. This arrangement, with the first connecting rod 41 and the first grip portion 42 cooperating with each other, facilitates gripping and rotation by the operator.

[0042] For example, in this embodiment, the first connecting rod 41 can be locked to the second end of the cross bracket 2 by means of a pin structure commonly used in the art.

[0043] Specifically, the positioning handle 3 includes a second connecting rod 31 that extends along a first direction and is rotatably connected at one end to the first end of the cross bracket 2. The second connecting rod 31 can rotate around the first direction. With the above configuration, when the socket body 1 is fitted onto the bolt structure and the balance handle 4 is rotated, the positioning handle 3 can remain stationary relative to the bolt structure, allowing the construction personnel to press the positioning handle 3 more easily, thereby ensuring the stability of the socket wrench.

[0044] For example, in this embodiment, a transition bearing 311 is provided at one end of the second connecting rod 31 near the cross bracket 2, and the transition bearing 311 is connected to the first end of the cross bracket 2. In the above arrangement, the transition bearing 311 is a bearing structure commonly used in the art, which is convenient for the use of local materials, has a simple structure, strong durability, and simple assembly steps.

[0045] Alternatively, in other embodiments, the adapter bearing 311 may not be provided. The first end of the cross bracket 2 is provided with a sliding groove, and the end of the second connecting rod 31 is provided with a slider that can slide and engage with the sliding groove. This can also realize the rotational connection between the cross bracket 2 and the second connecting rod 31. The specific structure can be referred to the prior art, and will not be described in detail here.

[0046] Specifically, the positioning handle 3 also includes a second gripping part 32, which is sleeved on the end of the second connecting rod 31 away from the cross bracket 2. The second gripping part 32 is provided with an anti-slip structure. With the above configuration, the second connecting rod 31 and the second gripping part 32 cooperate with each other, making it convenient for the operator to grip and rotate.

[0047] For example, in this embodiment, the anti-slip structure can be an anti-slip mat, such as a rubber mat; or, the anti-slip structure can be an anti-slip protrusion, which can be a dotted protrusion or a textured protrusion of any shape, as long as it can increase the contact friction between its location and the worker's hand. Its specific form is similar to that in the prior art, and is not specifically limited in this embodiment.

[0048] Preferably, in this embodiment, apart from the anti-slip structure, the material of the remaining structure can be carbon steel or stainless steel to ensure the support strength of the pipe wrench; in other embodiments, other materials can also be used, which are not limited here.

[0049] Specifically, the socket body 1 is available in various sizes, and each type of socket body 1 is detachably connected to the first end of the cross bracket 2. This configuration allows the socket body 1 to be adapted to different bolt structures, thereby enhancing the versatility of the socket wrench.

[0050] Specifically, the cross bracket 2 includes an extension rod, one end of which is detachably connected to the socket body 1, and the other end is detachably connected to the first end of the cross bracket 2. The extension rod allows the socket wrench to be used in narrower locations, thereby further improving its versatility.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
