[0020] A labor-saving tire enclosure vulcanization sealing device, such as Figure 1 As shown, it includes a sealing steel ring 1 and an expansion mechanism 2. A V-shaped positioning clip 19 is arranged around the sealing steel ring 1. Through the V-shaped positioning clip 19, the sealing steel ring 1 can be easily positioned and fitted onto the encapsulation sleeve, preventing the sealing steel ring 1 from shifting or falling off during subsequent expansion. The sealing steel ring 1 has a break point 3, forming two ends at the break point 3. For ease of understanding, these two ends will be referred to as end a and end b. A differential adjustment component 4 is provided inside the sealing steel ring 1 at the break point 3, and as shown... Figure 2 As shown, the differential adjustment assembly 4 specifically includes a differential plate 10 and a positioning ring 11. One end of the differential plate 10 is fixed to end a of the sealing steel ring 1, and the other end is set as a movable end. The positioning ring 11 is set on end b of the sealing steel ring 1, and the movable end of the differential plate 10 passes through the positioning ring 11. During the expansion or contraction of the sealing steel ring 1, end a and end b will move away from or towards each other. The cooperation between the differential plate 10 and the positioning ring 11 can stabilize the sealing steel ring 1 during the expansion or contraction process, compensate for the gap generated at the break point 3, and ensure that the sealing steel ring 1 always maintains a complete ring shape. Therefore, while making expansion easier, it also ensures that the sealing sleeve can be fully pressed, ensuring the sealing effect.

[0021] likeFigure 2 As shown, the expansion mechanism 2 specifically comprises a pressing rod 5, a sliding sleeve 6 and a gear driving assembly 7, wherein the pressing rod 5 is rotationally connected with the compensation adjusting assembly 4, and specifically, a connecting seat 12 can be arranged on the movable end of the compensation sheet 10, and the pressing rod 5 is rotationally arranged on the connecting seat 12 through a rotating shaft; the sliding sleeve 6 is sleeved on the pressing rod 5 and can slide along the pressing rod 5; the gear driving assembly 7 is arranged on the sliding sleeve 6; the pressing rod 5 is provided with a gear slot 8 matched with the gear driving assembly 7, and the cooperation between the gear driving assembly 7 and the gear slot 8 can drive the sliding sleeve 6 to move on the pressing rod 5.

[0022] As shown in Figure 1 , the sliding sleeve 6 and the sealing steel ring 1 are provided with a detent assembly 9, as shown in Figure 3 , Figure 4 , the detent assembly 9 specifically comprises a detent block one 17 and a detent block two 18, wherein the detent block one 17 is arranged at the bottom of the sliding sleeve 6, and the detent block two 18 is arranged at the inner side of the sealing steel ring 1 and is located on the side closer to the b end; when the pressing rod 5 rotates towards the sealing steel ring 1, the detent block two 18 will be in contact with the sealing steel ring 1, and when the sliding sleeve 6 moves outward, the detent block two 18 will be pressed against the detent block one 17; since the pressing rod 5 is connected with the connecting seat 12, the connecting seat 12 is fixed with the compensation sheet 10, and the compensation sheet 10 is fixed on the a end, when the sliding sleeve 6 moves outward, the rotating end of the pressing rod 5 will press the a end of the sealing steel ring 1, and the pressing force of the detent block two 18 and the detent block one 17 will be applied on the b end of the sealing steel ring 1, so as to drive the a end and the b end to move away from each other, and the sealing steel ring 1 expands.

[0023] As shown in Figure 3 , Figure 4As shown, the gear driving assembly 7 specifically comprises a driving pressure rod 13, a gear piece 14, an arc-shaped pressure piece 15 and a limiting piece 16. The driving pressure rod 13 is composed of a rod handle and a reversed U-shaped seat at the top, and is rotationally arranged on the sliding sleeve 6. Specifically, the reversed U-shaped seat is sleeved outside the sliding sleeve 6, and then a rotating shaft is used for connection. The gear piece 14 is rotationally arranged in the sliding sleeve 6 and extends to outside the top of the sliding sleeve 6. The rotating shaft of the gear piece 14 can be arranged as the same as the driving pressure rod 13. The gear piece 14 is engaged with the tooth groove 8 of the pressure rod 5. Therefore, when the gear piece 14 rotates, the sliding sleeve 6 will move on the pressure rod 5. The arc-shaped pressure piece 15 is rotationally arranged on the driving pressure rod 13, specifically in the reversed U-shaped seat of the driving pressure rod 13. One end of the arc-shaped pressure piece 15 is in abutment with the gear teeth of the gear piece 14. Therefore, when the driving pressure rod 13 rotates, the arc-shaped pressure piece 15 will abut against the gear teeth of the gear piece 14, thereby driving the gear piece 14 to rotate, and the sliding sleeve 6 will move and make the abutment of the clamping block two 18 and the clamping block one 17, so that the sealing steel ring 1 is expanded. The limiting piece 16 is rotationally arranged in the sliding sleeve 6 and extends to outside the top of the sliding sleeve 6. The limiting piece 16 is located on one side of the gear piece 14, which can adopt a right trapezoidal section, and the acute angle part is in contact with the gear teeth of the gear piece 14. An elastic pressure piece is arranged between the limiting piece 16 and the inner wall of the sliding sleeve 6. The elastic pressure piece can adopt a torsion spring or other components with elastic pressure ability. Under the action of the elastic pressure piece, the limiting piece 16 will keep in abutment with the gear teeth of the gear piece 14.

[0024] When the driving pressure rod 13 rotates from one side of the limiting piece 16 to the other side, the arc-shaped pressure piece 15 abuts against the gear piece 14, so that the gear piece 14 rotates forward, the sliding sleeve 6 moves, and the gear teeth of the gear piece 14 abut against the limiting piece 16 to rotate backward, so that the limiting piece 16 does not interfere with the rotation of the gear piece 14. When the gear piece 14 stops rotating, the limiting piece 16 is reset forward under the action of the elastic pressure piece, and the inclined waist surface abuts against the gear teeth of the gear piece 14, so that the gear piece 14 cannot rotate backward. Therefore, the driving pressure rod 13 can be operated and rotated multiple times. However, it should be noted that, unless the expansion is released, the arc-shaped pressure piece 15 on the other side should not abut against the limiting piece 16 when the driving pressure rod 13 is operated and rotated toward the limiting piece 16, because when the limiting piece 16 is abutted by the arc-shaped pressure piece 15, it will rotate backward, and the limiting of the gear piece 14 will also be released.

[0025] The utility model discloses a set breakpoint 3 and difference adjusting assembly 4 on the sealing steel ring 1 of the package cover, make the expansion of the size of steel ring more easily realize, and set up expansion mechanism 2 into by top pressure rod 5, sliding sleeve 6 and gear drive assembly 7 several parts, utilize the meshing and clamping of gear to realize top pressure and expand, the lever structure of the current simple reliance on force down is changed into through the transmission ratio of gear, because the gear number ratio, when driving pressure rod 13 adds a smaller force, this force will be amplified by transmission ratio and is passed to gear, thereby generating a larger output force, thereby greatly reduce the strength required to use expansion sealing steel ring 1, and can adopt the way of repeatedly pushing to realize the expansion, the required strength is applied separately, compared with the traditional structure needs one-time big force to press to the bottom mode, also more convenient and labor saving.
