Description
Technical Field
[0001] This application relates to the field of grooving tools, specifically to a convenient grooving tool for concealed pipe installation. Background Technology
[0002] In building construction, trenching before concealed pipe installation is a crucial step. Traditional trenching tools have several drawbacks. Firstly, most trenching tools are of fixed length, making it difficult to adapt to trenching needs of varying distances and spatial locations. Workers may need to frequently change tools or adjust their posture, leading to inefficiency, fatigue, and safety hazards. Secondly, the significant recoil force generated during trenching affects not only the quality and accuracy of the trenching but also the potential damage to the tools, shortening their lifespan. Furthermore, the grip design of traditional tools is often inadequate, making it difficult for workers to find a comfortable grip and application angle, impacting work efficiency and construction quality. For example, while some existing patented trenching tools possess certain functions, they still fall short in terms of length adjustment, recoil damping, and ease of grip.
[0003] Therefore, in order to improve the efficiency and quality of pipe concealment trenching, a convenient pipe concealment trenching tool that can flexibly adjust the length, effectively buffer shock, and is easy to hold and apply force is needed. Summary of the Invention

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0027] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0028] like Figures 1 to 6 As shown, a convenient grooving tool for concealed pipe installation includes a cutting machine 100, a telescopic component 200, a buffer component 300, and a gripping component 400. Specifically, the cutting machine 100 is used for grooving, the telescopic component 200 adjusts the length of the tool and supports the cutting machine 100, and the gripping component 400 is added to the telescopic component 200 for support, making it convenient for workers to hold and apply force. The buffer component 300 connects the cutting machine 100 and the telescopic component 200, and utilizes the torsion of a spring on the buffer component 300... This buffers the vibration generated when the cutting machine 100 is grooving, and adapts to the force applied by the operator during grooving. That is, when the operator pushes the telescopic component 200 and the grip component 400 to make the cutting machine 100 contact the wall and continues to apply force, the spring torsion spring on the buffer component 300, i.e., the contact between the cutting machine 100 and the telescopic component 200, reduces the contact area. When the cutting machine 100 is working, the elasticity can keep the cutting machine 100 in contact with the wall, avoiding the impact of changes in the force applied by the operator's hand on the grooving quality.
[0029] The cutting machine 100 is used for grooving. When in use, the external power supply drives the cutting machine 100. The cutting machine 100 is a complete cutting device and is a mature existing technology. It uses the rotation of its blades to groove the wall surface, which facilitates the subsequent concealed installation of pipes.
[0030] The telescopic assembly 200 includes a rear rod 201, a front rod 202, and an adjustment frame 207. The front rod 202 is sleeved on the rear rod 201. The two ends of the adjustment frame 207 are fixedly connected to the rear rod 201 and slidably connected to the front rod 202, respectively. The rear rod 201 is used to slide on the front rod 202 to change the tool length, and the adjustment frame 207 is used for hand gripping.
[0031] Specifically, the telescopic assembly 200 includes a control plate 203, a spring 204, and a lower insertion shaft 205. All three lower insertion shafts 205 are fixedly installed on the control plate 203, and each lower insertion shaft 205 is fitted with a spring 204. The spring 204 is fixed to the control plate 203 and the front rod 202. Both the rear rod 201 and the front rod 202 have through holes. The operator holds the control plate 203 with their hand and moves it away from the front rod 202. This causes the control plate 203 to pull the three lower insertion shafts 205 to slide within the through holes on the front rod 202, and stretches the springs 204 on the lower insertion shafts 205, causing them to disengage from the through holes of the rear rod 201. This releases the restriction on the rear rod 201, allowing the operator to control the rear rod 201 to slide on the front rod 202 with their other hand. This adjusts the length formed by the rear rod 201 and the front rod 202, facilitating grooving work. After adjusting to the appropriate position, the operator releases the control plate 203. Under the action of the springs 204, the control plate 203 and the lower insertion shafts 205 move closer to the front rod 202, allowing the lower insertion shafts 205 to insert into the new through holes of the rear rod 201, thus fixing the rear rod 201 to the front rod 202.
[0032] The buffer assembly 300 includes a connecting seat 301, a connecting rod 303, and a torsion spring 306. The front rod 202 is sleeved on the connecting rod 303, and the torsion spring 306 and the connecting seat 301 are sleeved on the connecting rod 303. The two ends of the torsion spring 306 are respectively connected to the connecting seat 301 and the torsion spring 306. The connecting seat 301 is connected to the cutting machine 100. The torsion spring 306 is used to buffer the force of the cutting machine 100 and limit the angle between the cutting machine 100 and the telescopic assembly 200.
[0033] Specifically, the connecting seat 301 supports the cutting machine 100 and transmits the force of the cutting machine 100's vibration to the torsion spring 306 on the connecting rod 303 for buffering. In use, when the cutting machine 100 contacts the wall due to the push of the front rod 202, if the push continues, the cutting machine 100 will cause the connecting seat 301 to rotate around the axis of the connecting rod 303, changing the angle between the cutting machine 100 and the telescopic component 200, and twisting the torsion spring 306 to store force, ensuring the contact capability between the cutting machine 100 and the wall.
[0034] The grip assembly 400 includes a grip rod 405 and an adjusting rod 407. The grip rod 405 is disposed on the rear rod 201, and the adjusting rod 407 is disposed on the end of the grip rod 405 away from the rear rod 201. The grip rod 405 is used for hand gripping, and the end of the adjusting rod 407 near the adjusting frame 207 is connected to the adjusting frame 207. The adjusting frame 207 is used to adjust the tilt angle between the grip rod 405 and the rear rod 201.
[0035] Specifically, the angle between the grip rod 405 and the rear rod 201 is adjusted to accommodate the force application habits of workers in different grooving operations. That is, in grooving vertical walls and top walls, the force application angle of workers changes, and different workers have different usage habits. By adjusting the angle between the grip rod 405 and the rear rod 201, workers can be in an optimal operating mode. After adjusting the position of the grip rod 405, the grip rod 405 is fixed with the adjusting rod 407. The adjusting rod 407, the grip rod 405, and the rear rod 201 form a triangle, which can stabilize the position of the grip rod 405 and ensure the stability of the force applied by the worker.
[0036] like Figure 2 and Figure 5 As shown, the buffer assembly 300 includes a connecting ring 302, a left limiting nut 304, and a fixing ring 305. The connecting ring 302 is fixedly connected to the front rod 202. The connecting ring 302 is provided with a sliding groove. Both ends of the connecting rod 303 are provided with a threaded groove. The left limiting nut 304 is provided on a threaded groove. The fixing ring 305 is fixedly installed on the end of the left limiting nut 304 facing the connecting ring 302. The fixing ring 305 is provided with a slider that matches the sliding groove of the connecting ring 302. The connecting ring 302 and the front rod 202 are connected through the threaded groove of the connecting rod 303, the left limiting nut 304, and the fixing ring 305.
[0037] Specifically, the left limiting nut 304 is fixed by the threaded groove at one end of the connecting rod 303. The left limiting nut 304 is inserted into the groove of the connecting ring 302 by the slider on the fixing ring 305 to limit the connecting ring 302, thereby limiting the front rod 202. Thus, after installation, the connecting rod 303, the left limiting nut 304, the fixing ring 305, the connecting ring 302 and the front rod 202 form a whole, which facilitates the buffering of angle changes during subsequent work.
[0038] like Figure 2 and Figure 5 As shown, the buffer assembly 300 includes a right limiting nut 307 and a fixing plate 308. The right limiting nut 307 and the fixing plate 308 are respectively fixedly connected to the two ends of the torsion spring 306. The right limiting nut 307 is connected to the threaded groove on the connecting rod 303. The fixing plate 308 is provided with a through hole. The connecting seat 301 is provided with a through hole corresponding to the fixing plate 308. The fixing plate 308 and the connecting seat 301 are connected by bolts.
[0039] Specifically, the right limiting nut 307 is screwed into the threaded groove at the end of the connecting rod 303 away from the left limiting nut 304, thus fixing it to the connecting rod 303 through the thread, and making the fixing plate 308 tightly against the connecting seat 301. After the right limiting nut 307 is tightened, the fixing plate 308 is fixedly connected to the connecting seat 301 by bolts, forming a fixed connection. The fixing plate 308 is also sleeved on the connecting ring 302. When the cutting machine 100 is grooving, the blade experiences a counter-vibration due to the force, thereby... The cutting machine 100 drives the connecting seat 301 to rotate around the axis of the connecting rod 303. Because the right limit nut 307 is threadedly connected to the connecting rod 303, it forms a fixed connection. Thus, the right limit nut 307, the connecting rod 303, the left limit nut 304, the fixing ring 305, the connecting ring 302 and the front rod 202 form a fixed connection. Then, the connecting seat 301 drives the torsion spring 306 to twist on the right limit nut 307 through the fixing plate 308, which buffers the reaction vibration of the cutting machine 100.
[0040] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the grip assembly 400 includes an inner insert rod 401, a middle plate 402, a lower connector 403, and a middle rod 404. The inner insert rod 401 and the lower connector 403 are respectively fixedly installed at the two ends of the middle plate 402. The inner insert rod 401 is inserted into the rear rod 201. The two ends of the middle rod 404 are respectively rotatably connected to the lower connector 403 and fixedly connected to the grip rod 405, and the middle rod 404 and the grip rod 405 are connected at a 90-degree angle.
[0041] Specifically, the inner insertion rod 401 is inserted into the rear rod 201, and the insertion behavior of the inner insertion rod 401 is limited and controlled by the contact between the intermediate plate 402 and the rear rod 201. The lower connector 403 and the intermediate rod 404 are connected to the gripping rod 405. The 90-degree angle between the intermediate rod 404 and the gripping rod 405 creates a certain space between the gripping rod 405 and the rear rod 201. Therefore, when the angle between the gripping rod 405 and the rear rod 201 is 0 degrees, the gripping rod 405 will not interfere with the adjusting frame 207.
[0042] like Figure 6 As shown, the gripping rod 405 is provided with a groove for engaging the adjusting frame 207.
[0043] Specifically, when storing the grip rod 405, bring the grip rod 405 close to the adjustment frame 207. The grip rod 405 and the adjustment frame 207 will cooperate through the groove of the grip rod 405, that is, the grip rod 405 is fastened on the adjustment frame 207, which makes it easy to store.
[0044] like Figure 4 and Figure 6As shown, the grip assembly 400 includes a threaded rod 406, an adjusting block 408, and upper insert shafts 409. The threaded rod 406 is fixedly mounted on the gripping rod 405. One end of the adjusting rod 407 near the gripping rod 405 is sleeved on the threaded rod 406. The threaded rod 406 is provided with threads and bolts, which restrict the position of the adjusting rod 407. The adjusting block 408 is rotatably mounted on the end of the adjusting rod 407 away from the gripping rod 405. Two upper insert shafts 409 are fixedly mounted on the adjusting block 408. The upper insert shafts 409 are used to insert into the through holes of the adjusting frame 207, thereby restricting the adjusting rod 407.
[0045] Before use, first unscrew the thread on the threaded rod 406, i.e., move it away from the gripping rod 405. It is not necessary to completely detach it from the threaded rod 406. It is sufficient to ensure that when the adjusting rod 407 moves on the threaded rod 406, the upper insertion shaft 409 on the adjusting block 408 can disengage from the through hole of the adjusting frame 207. After controlling the upper insertion shaft 409 to disengage from the adjusting frame 207, the restriction on the gripping rod 405 is released. Then, the operator can control the movement of the gripping rod 405, causing the intermediate rod 404 to rotate on the lower connector 403, thereby adjusting the angle between the gripping rod 405 and the rear rod 201. After adjusting to the appropriate angle, control the bolt on the threaded rod 406 to screw in, and at the same time, cause the upper insertion shaft 409 on the adjusting block 408 to insert into the corresponding through hole on the adjusting frame 207. This allows the adjusting rod 407 to support the gripping rod 405 and the threaded rod 406, fixing the angle between the gripping rod 405 and the rear rod 201, thus completing the adjustment of the angle of the gripping rod 405.
[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
