[0002] Hot melt tape is often needed in the production, connection and repair of skeleton pipes. Through the hot melting principle of hot melt tape, the surface material of the skeleton pipe can be melted and bonded together to form a tight connection, so as to improve the quality index of the pipe surface.

[0003] When using hot melt tape, workers often need to place the hot melt tape on the part that needs to be connected or repaired, and then use a hot melt tool to heat it until it melts. Then, quickly fit the melted hot melt tape to the skeleton tube, and apply appropriate pressure to make it tightly bonded. After cooling and solidification, a solid connection will be formed between the hot melt tape and the skeleton tube.

DETAILED DESCRIPTION

[0036] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] The utility model embodiment specifically provides a self-locking hot melt tape that is easy to install, please refer to Figure 1 , including a belt drum 1, a clamping column 2, a mounting hole 3, a bolt 4 and a clamping assembly 5;

[0038] The belt drum 1 includes a belt reel 11, a rotating column 12 and a hot melt belt 13. The belt reel 11 is rotatably arranged at both ends of the rotating column 12. The hot melt belt 13 is wound around the outside of the rotating column 12. The inner end of the hot melt belt 13 is fixed to the rotating column 12, so that the hot melt belt 13 can be rotated by driving the rotating column 12 when it is pulled out, so that it can be quickly pulled out. The hot melt belt 13 is provided with a screw hole 14, and the screw hole 14 is used for the hot melt belt 13 to be installed and wound around the outer periphery of the pipe for positioning and self-locking.

[0039] During implementation, both ends of the clamping column 2 are fixed to the tape reel 11, and the mounting hole 3 is opened on the surface of the clamping column 2. The inner diameter of the mounting hole 3 is larger than the size of the nut of the bolt 4, so that the bolt 4 can be inserted into the mounting hole 3. After the nut part of the bolt 4 is inserted into the mounting hole 3, it is connected with the clamping component 5. After the hot melt tape 13 is wrapped around the pipe, the entire tape drum 1 is rotated to drive the clamping component 5 to initially rotate the bolt 4, so that the bolt 4 is connected to the screw hole 14 and separated from the clamping component 5. When the hot melt tape 13 is used, the bolt 4 and the screw hole 14 are quickly installed to make the hot melt tape 13 self-locking, thereby improving the convenience of installation.

[0040] Specifically, there are more than two screw holes 14, and the screw holes 14 are arranged at equal intervals along the length direction of the hot melt tape 13. The spacing distance of the screw holes 14 on each specification of the hot melt tape 13 corresponds to the outer circumference length of a pipe, that is, when the hot melt tape 13 is wrapped around the pipe for one or several weeks, two or more screw holes 14 can be superimposed and aligned to facilitate the rotation of the bolt 4 into the screw hole 14, so that the hot melt tape 13 can remain self-locking and avoid elastic loosening.

[0041] For further information, please refer to Figure 2 and Figure 3 The interior of the clamping column 2 is a cavity structure communicated with the mounting hole 3. The clamping assembly 5 includes a driving frame 51, a clamping frame 52 and a synchronization assembly 53. The driving frame 51 is slidably arranged on the clamping column 2. The clamping frame 52 and the synchronization assembly 53 are both arranged in the cavity. The inner end of the driving frame 51 is connected to the clamping frame 52 and the synchronization assembly 53, so that the clamping frame 52 clamps and separates the bolt 4 through the driving frame 51 and the synchronization assembly 53. When the hot melt tape 13 is wound around the outer periphery of the pipe and the two screw holes 14 are superimposed and aligned, the hot melt tape 13 can be cut, and then the bolt 4 can be installed into the two screw holes 14, so that the hot melt tape 13 is self-locking, and there is no need to install a clamp, and the clamping frame 52 is separated from the bolt 4 to facilitate subsequent welding.

[0042] The driving frame 51 includes a button 511, a first driving frame 512, a second driving frame 513 and a first pressing block 514. The outer side of the button 511 is slidably connected to the clamping column 2. The first driving frame 512 and the second driving frame 513 are parallel to each other, and the outer ends of the first driving frame 512 and the second driving frame 513 are fixed to the button 511. The first driving frame 512 and the second driving frame 513 are both slidably arranged in the cavity inside the clamping column 2, so that the two driving frames are driven to slide toward the inside of the clamping column 2 at the same time by pressing the button 511.

[0043] During implementation, the first pressing block 514 is fixed on the first driving frame 512 , and the first driving frame 512 applies force to the clamping frame 52 through the first pressing block 514 , so that the clamping frame 52 can move after being forced and separate from the bolt 4 , so that the bolt 4 can be removed from the clamping column 2 .

[0044] Among them, there are two clamping frames 52, and the clamping frames 52 are symmetrically arranged on the upper and lower sides of the bolt 4, so as to facilitate clamping the bolt 4 at both ends of the bolt 4 through the clamping frames 52, so that the bolt 4 can be clamped and placed in place and conveniently removed when used.

[0045] Furthermore, the clamping frame 52 includes a sliding frame 521, a clamping block 522 and a spring 523. The sliding frame 521 is integrally fixed inside the clamping column 2. The outer side of the clamping block 522 slides linearly along the sliding frame 521. The spring 523 is installed in the sliding frame 521. The two ends of the spring 523 are respectively fixed to the sliding frame 521 and the clamping block 522, so that the spring 523 provides a sliding reset elastic force for the clamping block 522, so that the clamping block 522 can be quickly reset after displacement, thereby ensuring stable clamping of the bolt 4.

[0046] During implementation, the nut of the bolt 4 is a hexagonal structure, and a clamping groove 524 matching the outer contour of the nut of the bolt 4 is opened on the inner side of the clamping block 522, so that the nut of the bolt 4 can be tightly inserted into the clamping block 522 through the clamping groove 524, so as to improve the stability of the bolt 4 when placed.

[0047] For details, please refer to Figure 3 and Figure 4 The synchronization component 53 includes a first slide 531, a second slide 532, a latching tooth 533, a gear 534 and a second pressing block 535. The first slide 531 and the second slide 532 are arranged parallel to each other and spaced apart. The first slide 531 and the second slide 532 are slidably installed in the clamping column 2. The outer end of the first slide 531 is fixed to the second driving frame 513 so that the first slide 531 is driven to slide and move through the second driving frame 513. The adjacent surfaces of the first slide 531 and the second slide 532 are arranged with latching teeth 533. The gear 534 is arranged with a latching tooth 533. The bottom end of 534 is rotatably connected to the clamping column 2, and the outer side of the gear 534 is meshed with the first slide 531 and the second slide 532 through the latch tooth 533, so that when the gear 534 rotates, it can drive the first slide 531 and the second slide 532 to slide in different directions. The second pressure block 535 is fixed on the second slide 532, and the second slide 532 is in contact with the clamping block 522 through the second pressure block 535, so that when the second slide 532 slides upward, it can drive the clamping block 522 to separate from the bolt 4 through the second pressure block 535.

[0048] During implementation, the first driving frame 512 and the second slide 532 apply force to the lower and upper clamping blocks 522 separately through the first pressure block 514 and the second pressure block 535, so that when the button 511 is pressed down, the first driving frame 512 drives the first pressure block 514 to press down the lower clamping block 522, and the second slide 532 is forced to move upward, and the upper clamping block 522 is pushed up by the second pressure block 535, so that the clamping blocks 522 on both sides of the bolt 4 can be moved outward and opened synchronously, so that the two clamping blocks 522 are separated from the bolt 4, so that the bolt 4 can be plugged into the screw hole 14, and when the two ends of the hot melt tape 13 are welded and fixed in place, the bolt 4 can be retracted, so that the clamping blocks 522 are clamped again by the spring 52, so as to facilitate subsequent use.

[0049] Among them, a mounting frame 536 is fixedly provided inside the clamping column 2, and sliding grooves 537 are opened on the upper and lower surfaces of the first slide 531 and the second slide 532. A slider 538 is fixedly installed on the inner side of the mounting frame 536, and the mounting frame 536 cooperates with the sliding rod of the sliding groove 537 through the slider 538, so that the first slide 531 and the second slide 532 can be stably slid and used inside the clamping column 2 to meet the use requirements.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
