Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe wrench technology, and more specifically to a pipe wrench for assembling steel structure space frame members. Background Technology
[0002] Pipe wrenches are a common tool mainly used to fix pipes or pipe fittings during pipe installation and maintenance. They have strong clamping force and can firmly hold pipes, making it convenient for workers to tighten or loosen them.
[0003] A standard pipe wrench typically consists of two adjustable jaws and a handle. The jaws can clamp pipes of different sizes, while the handle is used to apply force.
[0004] However, when using conventional pipe wrenches to tighten steel structure space frame members, the numerous connecting rods within the space frame obstruct the handle, limiting its rotation to a very small angle. This undoubtedly causes considerable inconvenience to the installation of the space frame and its use remains somewhat limited. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a pipe wrench for assembling steel structure space frame members, so as to solve the problem that the handle of the existing pipe wrench is blocked by the space frame members when tightening the members in the space frame, resulting in poor rotation.
[0006] This utility model provides the following technical solution: a pipe wrench for assembling steel structure space frame members, including a pipe wrench body, the handle of the body is provided with an extension handle that can be slidably extended and bent at an angle, the extension handle includes a sliding extension part and a rotating bending part, the sliding extension part is slidably sleeved on the handle of the body, and the rotating bending part is located at the end of the sliding extension part away from the handle.
[0007] Furthermore, the sliding extension includes a sliding sleeve and an extension handle. The sliding sleeve is slidably fitted onto the handle, and the extension handle is slidably inserted inside the sliding sleeve. The rotating bending part is located at the end of the extension handle away from the sliding sleeve. The sliding sleeve has a built-in limiting component to prevent the handle and extension handle from disengaging from the sliding sleeve. The surface of the sliding sleeve is provided with a fixing component to fix the position of the sliding sleeve and the extension handle.
[0008] Furthermore, the limiting assembly includes limiting rings and limiting plates, with two limiting rings and two limiting plates. The two limiting rings are fixedly installed at both ends of the sliding sleeve, one limiting plate is fixedly installed at the end of the handle away from the working end of the pipe wrench, and the other limiting plate is fixedly installed at the end of the extension handle inside the sliding sleeve. Both limiting plates are slidably disposed inside the sliding sleeve, and the handle and the extension handle are slidably inserted through the middle of the limiting rings. At the same time, the limiting rings can prevent the limiting plates from sliding out of the sliding sleeve.
[0009] Furthermore, the fixing component includes a threaded seat and a tightening bolt. There are two threaded seats and two tightening bolts. The two threaded seats are fixedly installed on the surface of the sliding sleeve and are respectively close to both ends of the sliding sleeve. A threaded hole is opened in the middle of the threaded seat and extends into the interior of the sliding sleeve. The tightening bolt is threadedly installed in the threaded hole.
[0010] Furthermore, the rotating bending part includes a rotating handle, a rotating groove, and a rotating joint. The rotating groove is opened at the end of the extended handle away from the sliding sleeve, and the rotating joint is fixedly installed at the end of the rotating handle and rotatably installed in the rotating groove.
[0011] Furthermore, the cross-sectional shape of the rotating handle is the same as that of the extension handle, and when the rotating handle and the extension handle are collinear, the rotating handle can be slidably inserted into the sliding sleeve.
[0012] Furthermore, a baffle is fixedly installed at the end of the rotating handle away from the extension handle, and the baffle cannot be inserted into the sliding sleeve.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. In the entire process of use, the lever arm length and gripping position of the pipe wrench can be changed by sliding extension and rotating bending parts, so as to facilitate the user to rotate the pipe wrench from multiple positions, thereby avoiding interference caused by the on-site space frame members to the rotation of the pipe wrench, and greatly facilitating the assembly of space frame members.
[0015] 2. In the process of using this utility model, since the lever arm of the pipe wrench can be freely adjusted in length and grip angle according to the usage requirements, the entire pipe wrench can be used in more places with more interference, which greatly improves the applicability of the pipe wrench.

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.
[0022] Figure 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1-4 The present invention will be further described below.
[0023] A pipe wrench for assembling steel structure space frame members includes a main body 1 of the pipe wrench. The handle 2 of the main body 1 is provided with an extension handle that can be slidably extended and bent at an angle. The extension handle includes a sliding extension part and a rotating bending part. The sliding extension part is slidably sleeved on the handle 2 of the main body 1, and the rotating bending part is located at the end of the sliding extension part away from the handle 2.
[0024] When in use, if the space frame members interfere with the rotation of the pipe wrench, the length of the lever arm and the gripping position of the entire pipe wrench can be changed by sliding the extension part and rotating the bending part, so that the user can easily rotate the pipe wrench from multiple positions.
[0025] The sliding extension part includes a sliding sleeve 3 and an extension handle 4. The sliding sleeve 3 is slidably fitted onto the handle 2, and the extension handle 4 is slidably inserted inside the sliding sleeve 3. The rotating bending part is located at the end of the extension handle 4 away from the sliding sleeve 3. The sliding sleeve 3 has a built-in limiting component to prevent the handle 2 and the extension handle 4 from disengaging from the sliding sleeve 3. The surface of the sliding sleeve 3 is provided with a fixing component to fix the position of the sliding sleeve 3 and the extension handle 4. Thus, by simply releasing the fixing component, the sliding sleeve 3 can slide out along the direction of the handle 2, and the extension handle 4 can extend from the other end of the sliding sleeve 3 to lengthen the lever arm of the entire pipe wrench, or the handle 2 and the extension handle 4 can both be retracted into the sliding sleeve 3 to shorten the lever arm of the entire pipe wrench.
[0026] The limiting assembly includes two limiting rings 5 and two limiting plates 6. The two limiting rings 5 are fixedly installed at both ends of the sliding sleeve 3. One limiting plate 6 is fixedly installed at the end of the handle 2 away from the working end of the pipe wrench, and the other limiting plate 6 is fixedly installed at the end of the extension handle 4 inside the sliding sleeve 3. Both limiting plates 6 are slidably disposed inside the sliding sleeve 3. The handle 2 and the extension handle 4 are slidably disposed in the middle of the limiting rings 5. At the same time, the limiting rings 5 can prevent the limiting plates 6 from sliding out of the sliding sleeve 3. In this way, the sliding sleeve 3, the extension handle 4 and the handle 2 of the pipe wrench can be effectively prevented from disengaging.
[0027] The fixing assembly includes a threaded seat 7 and a tightening bolt 8. There are two threaded seats 7 and two tightening bolts 8. The two threaded seats 7 are fixedly installed on the surface of the sliding sleeve 3 and are respectively close to both ends of the sliding sleeve 3. A threaded hole is opened in the middle of the threaded seat 7 and extends into the interior of the sliding sleeve 3. The tightening bolt 8 is threaded into the threaded hole. In this way, the sliding sleeve 3 and the extension handle 4 can be fixed by simply tightening the tightening bolt 8, thereby fixing the lever arm of the entire pipe wrench.
[0028] The rotating bending part includes a rotating handle 9, a rotating groove 10, and a rotating joint 11. The rotating groove 10 is opened at the end of the extension handle 4 away from the sliding sleeve 3. The rotating joint 11 is fixedly installed at the end of the rotating handle 9 and is rotatably installed in the rotating groove 10. In this way, when in use, the rotating handle 9 can be rotated to make it form a certain angle with the extension handle 4, thereby further avoiding interference caused by the on-site grid members to the rotation of the pipe wrench.
[0029] The cross-sectional shape of the rotating handle 9 is the same as that of the extension handle 4. When the rotating handle 9 and the extension handle 4 are collinear, the rotating handle 9 can be slidably inserted into the sliding sleeve 3. In this way, the entire rotating handle 9 can also be stored in the sliding sleeve 3, which will facilitate the storage of the entire pipe wrench.
[0030] A baffle 12 is fixedly installed at the end of the rotating handle 9 away from the extension handle 4, and the baffle 12 cannot be inserted into the sliding sleeve 3. This will prevent the rotating handle 9 from being difficult to push out after it is completely retracted into the sliding sleeve 3.
[0031] Therefore, the complete usage procedure is as follows: when the nearby space frame members interfere with the handle 2 of the pipe wrench, causing the pipe wrench to not rotate properly, the tightening bolt 8 can be rotated to release the fixation on the sliding sleeve 3 and the extension handle 4. At this time, the sliding sleeve 3 can slide out along the direction of the handle 2, and the extension handle 4 can extend from the other end of the sliding sleeve 3 to lengthen the lever arm of the entire pipe wrench, or the handle 2 and the extension handle 4 can both be retracted into the sliding sleeve 3 to shorten the lever arm of the entire pipe wrench. At the same time, the rotating handle 9 can be rotated to make it form a certain angle with the extension handle 4, thereby avoiding interference caused by the space frame members on site to the rotation of the pipe wrench, and facilitating the installation of the space frame members.
[0032] In summary, during the entire usage process, the lever arm length and gripping position of the pipe wrench can be changed by sliding the extension part and rotating the bending part, which makes it convenient for the user to rotate the pipe wrench from multiple positions, thereby avoiding interference caused by the on-site space frame members to the rotation of the pipe wrench, and greatly facilitating the assembly of the space frame members.
[0033] Meanwhile, during use, the lever arm of the pipe wrench can be freely adjusted in length and grip angle according to usage requirements, which allows the pipe wrench to be used in more places with more interference, greatly improving the applicability of the pipe wrench.
[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
