Abstract
Description
Technical Field
[0001] The utility model relates to the field of sealing tools, in particular to a sealant shape-preserving tool. Background Art
[0002] Sealing and pressurizing to maintain air pressure balance is a basic requirement for aircraft manufacturing. Airtight areas, fuel tank areas, and isolated anti-corrosion areas all require sealants to be applied to the fuselage structure and connectors. To enhance the sealing effect, connectors should be sealed. Figure 1 As shown, sealant is first injected into the sealing cap 1. The sealant-filled sealing cap 1 is then moved downward from directly above the connector 2 to be sealed until the sealing cap 1 completely contacts the surface of the component. After the sealant is cured, the sealing cap 1 is removed, thereby achieving the sealing purpose. Currently, sealing is primarily performed manually by operators. However, due to varying operator experience, problems such as inaccurate sealing positioning and poor sealing often occur, often requiring extensive rework to achieve uniform sealing appearance and acceptable sealing quality. Furthermore, while waiting for the sealant to cure, the operator is required to constantly hold down the sealing cap by hand, which is time-consuming and labor-intensive, resulting in low sealing efficiency. Utility Model Content
[0003] In order to overcome the above-mentioned deficiencies in the existing sealing operation of sealant, the technical problem to be solved by the present invention is to provide a sealant shape-preserving tool that can improve the sealing quality and efficiency.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] A sealant shape-preserving tool comprises a base and a sealing cap, a cavity is provided in the middle of the base, a plurality of suction cups are provided at the bottom of the base, a guide rod is vertically provided on each side of the base, a slider is slidably provided on the two guide rods, a spring is sleeved on the guide rod between the slider and the base, a support rod is rotatably provided between the two sliders, the sealing cap is provided on the support rod, and its center is aligned with the center of the cavity of the base, a handle is provided on the support rod, a ratchet bar is vertically provided on the base, and the lower end of the ratchet bar is rotatably provided on the base, and when the sealing cap is pressed down to the sealing position, the handle can be stuck on the ratchet bar.
[0006] Furthermore, the cavity in the middle of the base is a circular structure, and scale lines are provided along the circumferential edge.
[0007] Furthermore, the upper end of the suction cup is hinged to the base.
[0008] Furthermore, the suction cup is a vacuum suction cup with a locking function.
[0009] Furthermore, the sealing cap has a variety of models that can be replaced, and the sealing cap is detachably fixed to the support rod through the clamping blocks on both sides.
[0010] Furthermore, the sealing cap further comprises a mounting seat, the center of the sealing cap is rotatably connected to the mounting seat, and the clamping block is arranged on the mounting seat.
[0011] Furthermore, a positioning block is provided on the side of the slider, and a first limit block and a second limit block are provided on the support rod. When the first limit block contacts the positioning block, the cover cap opening faces upward. When the support rod rotates 180°, the second limit block contacts the positioning block.
[0012] Furthermore, a first torsion spring is provided between both ends of the support rod and the slider. In a natural state, the support rod causes the first limit block to abut against the positioning block under the action of the first torsion spring, and the opening of the cover cap faces upward.
[0013] Furthermore, a second torsion spring is provided at the lower end of the ratchet bar. In a natural state, the side of the ratchet bar with the ratchet teeth abuts against the stopper of the base under the action of the second torsion spring, so that the ratchet bar is in a vertical state.
[0014] The beneficial effects of the present invention are as follows: by arranging a suction cup at the bottom of the base, the entire sealing tool can be fixed on the surface of the part during sealing, and at the same time, the center of the cavity can be aligned with the center of the connector to be sealed by adjusting the base to ensure that the sealing cap is aligned with the connector, thereby ensuring the accuracy of the sealing position; in addition, after the sealing cap is placed on the connector, the position of the sealing cap can be fixed by using a ratchet bar, and there is no need to press the sealing cap with hands all the time during vulcanization, which reduces the workload of the operator and improves the sealing efficiency.

[0026] like Figure 2-8 As shown, the utility model provides a sealant shape-preserving tool, including a base 3 and a sealing cap 1, a cavity 31 is provided in the middle of the base 3, a plurality of suction cups 32 are provided at the bottom of the base 3, a guide rod 4 is vertically provided on each side of the base 3, and sliders 5 are slidably provided on the two guide rods 4, a spring 6 is sleeved on the guide rod 4 between the slider 5 and the base 3, and a support rod 7 is rotatably provided between the two sliders 5, the sealing cap 1 is provided on the support rod 7, and its center is aligned with the center of the cavity 31 of the base 3, a handle 8 is provided on the support rod 7, and a ratchet bar 9 is vertically provided on the base 3, and the lower end of the ratchet bar 9 is rotatably provided on the base 3, and when the sealing cap 1 is pressed down to the sealing position, the handle 8 can be stuck on the ratchet bar 9.
[0027] The use process of the present utility model is as follows: first, the base 3 is moved to the top of the connector 2 to be sealed, so that the connector 2 passes through the cavity 31 on the base 3, and the position of the base 3 is adjusted to align the center of the cavity 31 with the center of the connector 2 as much as possible, and then the base 3 is pressed down so that the suction cup 32 below it is pressed and adsorbed on the part plate surface around the connector 2 to fix the entire conformal tool; then the sealing cap 1 is rotated to the state where the opening of the accommodating cavity is facing upward, as shown in FIG. Figure 2As shown, apply the release agent to the inner wall of the accommodating cavity and inject the sealant. After completion, turn the cover cap 1 to the state where the opening faces downward and press it down quickly, as shown in FIG. Figure 4 As shown, until it is completely covered on the connecting member 2, at the same time, the spring 6 is compressed, and finally the ratchet bar 9 is rotated to make the handle 8 clamped on the ratchet bar 9, and the clamping stability is ensured under the action of the spring 6, as shown Figure 8 As shown. After completing the above operations, release your grip, and the sealing cap 1 will remain stably sealed until the sealant is cured. Then, rotate the ratchet bar 9 to disengage it from the handle 8. Then, slowly shake and move the sealing cap 1 upwards. This completes the sealing of the connector 2. The base 3 can then be removed to seal the next connector 2. This tool can determine the sealing position before sealing and maintain the sealing cap 1 in place after sealing. This eliminates the need for the operator to constantly press the sealing cap 1, reducing workload and improving sealing efficiency and quality.
[0028] Since most connectors 2 are circular or symmetrical structures such as bolts and nuts, to improve positioning, the cavity 31 in the center of the base 3 can be configured as a circular structure, with scale lines 33 provided along the circumference. Before sealing, marking lines can be drawn on the component plate surface around the connector 2. The connector 2 and the cavity 31 can then be aligned by comparing the scale lines 33 with the marking lines.
[0029] When encapsulating connectors 2 on curved surfaces, the upper ends of the suction cups 32 can be hinged to the base 3 to improve the stability of the base 3 installation. This ensures that all suction cups 32 are vertically attached to the surface of the component, thereby increasing the stability of the base 3 installation. Preferably, the suction cups 32 are vacuum cups with a locking function to increase the suction force and facilitate assembly and disassembly.
[0030] Since there are many types of connectors 2 on airplanes, in order to improve the applicability of the tool, the cover cap 1 has a variety of different types for replacement, and the cover cap 1 can be detachably fixed to the support rod 7 through the clamping blocks 12 on both sides.
[0031] Furthermore, after sealing is complete, some sealant may adhere to the sealing cap 1. Simply moving the sealing cap 1 upward could damage the sealant. Therefore, a further solution is to provide the sealing cap 1 with a mounting seat 11, with the center of the sealing cap 1 pivotally connected to the mounting seat 11, and the retaining block 12 disposed on the mounting seat 11. This allows the sealing cap 1 to be gently rotated back and forth before being moved upward to separate it from the sealant. This ensures the integrity of the sealant.
[0032] In order to keep the cover cap 1 in a stable state with the opening facing upward or downward during the process of injecting glue and pressing down the cover cap 1, the present invention provides a preferred solution, such as Figure 6 、 Figure 7 As shown, a positioning block 51 is provided on the side of the slider 5, and a first limiting block 71 and a second limiting block 72 are provided on the support rod 7. When the first limiting block 71 contacts the positioning block 51, the opening of the closure cap 1 faces upward. When the support rod 7 rotates 180°, the second limiting block 72 contacts the positioning block 51, and the opening of the closure cap 1 faces downward. When the handle 8 is provided, it is necessary to ensure that the torque generated when it rotates to the left or right side of the support rod 7 can cause the first limiting block 71 or the second limiting block 72 to contact the positioning block 51, thereby ensuring the stability of the closure cap 1. In addition, in order to be able to move the closure cap 1 downward by driving the handle 8 during sealing, it is necessary to ensure that when the handle 8 is driven downward, the positioning block 51 can provide reverse support force to the first limiting block 71 or the second limiting block 72.
[0033] Furthermore, first torsion springs 73 are provided between the ends of the support rod 7 and the slider 5. In the natural state, the support rod 7, under the action of the first torsion springs 73, causes the first limit block 71 to abut against the positioning block 51, and the opening of the sealing cap 1 faces upward. After a sealing operation is completed, the sealing cap 1 automatically returns to the upward-facing state via the first torsion springs 73, reducing the number of operations and stabilizing the sealing cap 1, making it easier to apply release agent and inject sealant.
[0034] To automatically lock the handle 8, the ratchet bar 9 is provided with a second torsion spring 91 at its lower end. In its natural position, the ratchet-toothed side of the ratchet bar 9 abuts against the stopper 34 of the base 3 under the action of the second torsion spring 91, keeping the ratchet bar 9 in a vertical position. This automatically locks the handle 8 when the handle 8 is pressed downward. Once the cover is sealed, the handle 8 can be quickly and conveniently disengaged by slightly rotating the ratchet bar 9 to the left.
