Description

Technical Field

[0001] This utility model relates to the technical field of raw material tape, and in particular to a corrosion-resistant raw material tape. Background Technology

[0002] In the field of liquid pipeline installation, PTFE tape is a commonly used auxiliary material, widely applied at pipe joints to enhance the airtightness of the pipe connections.

[0003] However, the existing PTFE tape has obvious inconveniences in actual use. After the PTFE tape is wound onto the pipe, the operator needs to hold the PTFE tape roll with one hand to maintain its stability, and use scissors with the other hand to cut the PTFE tape. This operation method not only increases the complexity and difficulty of the operation, but also reduces the work efficiency. Utility Model Content

[0004] In view of the aforementioned problems with existing raw material tapes, the aim is to provide a corrosion-resistant raw material tape.

[0005] The specific technical solution is as follows:

[0006] A corrosion-resistant raw material tape includes a housing, a rotatable drum disposed within the housing, and a raw material tape body wound on the drum. The housing has a discharge pipe. The tape also includes:

[0007] A guide shaft is disposed inside the discharge pipe and is arranged parallel to the drum;

[0008] A support plate is disposed inside the discharge pipe and located on the side of the guide shaft near the discharge port of the discharge pipe, and the height of the top end face of the support plate is equal to the height of the top of the guide shaft.

[0009] Two lifting blocks are located above the support plate. One of the lifting blocks has a pressing block elastically connected to its bottom, and the other lifting block has a shearing blade installed at its bottom. The lowest height of the pressing block is lower than the lowest height of the shearing blade.

[0010] An operating block is provided above the discharge pipe, and the operating block and the lifting block are connected by at least one vertically arranged guide post. The guide post is slidably mounted on the discharge pipe, and a reset spring is sleeved on the outside of each guide post. The reset spring is located between the bottom of the operating block and the top of the discharge pipe.

[0011] As a further improvement and optimization of this solution, the top of the pressing block has several longitudinally arranged connecting rods, each of which can be slidably mounted on the lifting block in the longitudinal direction, and each of the connecting rods is fitted with a compression spring, which is located between the lifting block and the pressing block.

[0012] As a further improvement and optimization of this solution, several of the connecting rods are arranged at equal intervals along the length direction of the pressing block.

[0013] As a further improvement and optimization of this solution, the lengths of the pressing block and the shearing blade are both equal to the width of the raw material strip body.

[0014] As a further improvement and optimization of this solution, two guide posts are provided between each lifting block and the operating block, with the two guide posts located on both sides of the lifting block respectively.

[0015] As a further improvement and optimization of this solution, the top of the discharge pipe has an observation port.

[0016] As a further improvement and optimization of this solution, the outer shell includes a shell and a cover. The shell is a circular structure with a side opening. The cover is detachably installed at the opening of the shell. The drum is rotatably installed inside the shell. The discharge pipe is located on the circumferential surface of the shell and communicates with the shell.

[0017] As a further improvement and optimization of this solution, a mounting post is coaxially provided inside the housing, and the drum is coaxially rotatably sleeved outside the mounting post.

[0018] As a further improvement and optimization of this solution, the shell cover and the mounting post are connected by screws.

[0019] The positive effects of the above technical solution compared with the existing technology are:

[0020] (1) In this utility model, pressing the operating block drives the shearing blade to cut the raw material strip body at the outlet of the discharge pipe. When operating the shearing, there is no need to operate with both hands, making the operation convenient and quick, and improving work efficiency.

[0021] (2) When the pressing operation block is used in this utility model, the raw material strip body is first clamped by the pressing block, and then the raw material strip body is cut by the cutting blade, so as to avoid uneven cutting caused by hand shaking and pulling the raw material strip body outward during the cutting process.

[0022] (3) In this utility model, a guide shaft is provided. The raw material tape body enters the discharge pipe through the guide shaft. Therefore, the height of the raw material tape body entering the discharge pipe will not change with the degree of use of the raw material body on the drum, which makes it convenient for the raw material tape body to be pulled out and used.

Figure 2 This is a schematic diagram of the internal structure of a corrosion-resistant raw material tape according to this utility model. Figure 3 This is a schematic diagram of the internal structure of the discharge pipe of a corrosion-resistant raw material tape according to this utility model. Figure 4 This is a schematic diagram showing the connection between the pressing block and the lifting block of a corrosion-resistant raw material tape according to this utility model. Figure 1-4 The diagram illustrates a preferred embodiment of a corrosion-resistant raw material tape, comprising a housing 1, a drum 4 rotatably disposed within the housing 1, and a raw material tape body 5 wound on the drum 4. The housing 1 has a discharge pipe 13 and further includes a guide shaft 20, a support plate 30, two lifting blocks 6, and an operating block 2. The guide shaft 20 is disposed within the discharge pipe 13 and parallel to the drum 4. The support plate 30 is disposed within the discharge pipe 13 and located on the side of the guide shaft 20 near the discharge port of the discharge pipe 13, with the top end face height of the support plate 30 equal to the top height of the guide shaft 20. Both lifting blocks 6... Located above the support plate 30, one of the lifting blocks 6 has a pressing block 9 elastically connected to its bottom, and the other lifting block 6 has a shearing blade 10 installed at its bottom. The lowest height of the pressing block 9 is lower than the lowest height of the shearing blade 10. The operating block 2 is located above the discharge pipe 13, and the operating block 2 and the lifting block 6 are connected by at least one vertically arranged guide post 7. The guide post 7 is slidably mounted on the discharge pipe 13, and a return spring 8 is sleeved on the outside of each guide post 7. The return spring 8 is located between the bottom of the operating block 2 and the top of the discharge pipe 13.

[0032] In this embodiment, during actual use, one end of the raw material tape body 5 is pulled out through the opening of the discharge pipe 13 via the guide shaft 20 and wound onto the pipe fitting. Then, the operation block 2 can be manually pressed down, causing the two lifting blocks 6 to descend, so that the pressing block 9 and the shearing blade 10 descend synchronously. Since the height of the pressing block 9 is lower than the height of the shearing blade 10, the pressing block 9 first contacts the raw material tape body 5 and, with the cooperation of the support plate 30, elastically clamps the raw material tape body 5. As the operation block 2 is pressed down further, the shearing blade 10 contacts the raw material tape body 5 and, with the cooperation of the support plate 30, shears the raw material tape body 5.

[0033] In this embodiment, pressing the operating block 2 drives the shearing blade 10 to cut the raw material strip body 5 at the outlet of the discharge pipe 13. When operating the shearing, there is no need to operate with both hands, making the operation convenient and quick, and improving work efficiency.

[0034] In this embodiment, when the pressing operation block 2 is operated, the pressing block 9 first clamps the raw material strip body 5, and then the shearing blade 10 cuts the raw material strip body 5, so as to avoid uneven cutting caused by hand shaking and pulling the raw material strip body 5 during the cutting process.

[0035] In this embodiment, a guide shaft 20 is provided. The raw material tape body 5 enters the discharge pipe 13 through the guide shaft 20. Therefore, the height of the raw material tape body 5 entering the discharge pipe 13 will not change with the degree of use of the raw material body on the drum 4, which facilitates the pulling out and use of the raw material tape body 5.

[0036] Furthermore, as a preferred embodiment, the top of the pressing block 9 has a plurality of longitudinally arranged connecting rods 40, each of the connecting rods 40 being longitudinally slidably mounted on the lifting block 6, and each of the connecting rods is fitted with a compression spring 50, the compression spring 50 being disposed between the lifting block 6 and the pressing block 9.

[0037] Furthermore, as a preferred embodiment, several of the connecting rods 40 are arranged at equal intervals along the length direction of the pressing block 9.

[0038] Specifically, each of the connecting rods 40 slides longitudinally through the top of the lifting block 6 and is connected to the limiting plate 60.

[0039] Furthermore, in a preferred embodiment, the lengths of both the pressing block 9 and the shearing blade 10 are equal to the width of the raw material tape body 5, thereby improving the shearing effect on the raw material tape body 5.

[0040] Furthermore, as a preferred embodiment, two guide posts 7 are provided between each of the lifting blocks 6 and the operating block 2, with the two guide posts 7 located on both sides of the lifting block 6 respectively.

[0041] Furthermore, as a preferred embodiment, the top of the discharge pipe 13 has an observation port 131 to facilitate observation of the shearing condition of the raw material strip body 5 inside the discharge pipe 13.

[0042] Furthermore, as a preferred embodiment, the outer casing 1 includes a housing 11 and a cover 12. The housing 11 is a circular structure with a side opening. The cover 12 is detachably installed at the opening of the housing 11. The roll 4 is rotatably installed inside the housing 11. The discharge pipe 13 is located on the circumferential surface of the housing 11 and communicates with the housing 11. Since the housing 11 and the cover 12 are detachably configured, it is convenient to replace the roll 4 with a new one when the raw material tape body 5 on the roll 4 is used up.

[0043] Furthermore, in a preferred embodiment, a mounting post 111 is coaxially provided inside the housing 11, and the drum 4 is coaxially rotatably sleeved outside the mounting post 111.

[0044] Furthermore, in a preferred embodiment, the cover 12 and the mounting post 111 are connected by screws 3.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
