Description

Technical Field

[0001] The present invention relates to the field of accessories used in clothing, luggage, etc., and particularly to a waterproof pull handle. The waterproof pull handle has a content cavity that can be opened and closed and has water tightness. An object to be water-sealed, such as an electronic component, can be placed in the content cavity. The present invention also relates to a zipper applying the waterproof pull handle. Background Art

[0002] In order to enhance the use performance of a zipper, there is a zipper with a luminous zipper head in the prior art. For example, in a Chinese utility model patent with the publication number CN201675170U, it includes a zipper head body 1 and a pull ring 2 connected to the zipper head body 1. A circuit board 3, an LED chip 4, a battery 5, and a switch are provided inside the zipper head body 1. The LED chip 4, the battery 5, and the switch are respectively connected to the circuit board 3. The zipper head body 1 encapsulates and seals the circuit board 3, the LED chip 4, the battery 5, and the switch inside it by an integrally injection-molded method. This technical solution realizes the luminous function of the zipper through the LED chip 4. However, the battery 5 will be exhausted as the use time increases, and the integrally injection-molded LED chip 4 and battery 5 cannot be replaced or repaired.

[0003] To solve the above problems, the prior art also discloses a detachable luminous pull handle. For example, in a Chinese utility model patent with the publication number CN209807276U, it discloses a lighting rope pull handle, including a rope 1 and a pull handle body 2. Both ends of the rope 1 are fixedly connected to the pull handle body 2. The pull handle body 2 includes a housing 3 and a lighting assembly 4. An opening 31 is provided at one end of the housing 3, and the lighting assembly 4 is inserted into the housing 3 through the opening 31. Both ends of the rope 1 are fixedly connected to the housing 3. Summary of the Invention

[0004] In the above-mentioned Chinese utility model patent with the publication number CN209807276U, the lighting assembly 4 and the housing 3 are locked by a fixing pin 33. A first pin hole 414 is provided in a base 41 of the lighting assembly 4, and two second pin holes 32 coaxial with the first pin hole 414 are provided in the housing 3. The first pin hole 414 is penetrated by the fixing pin 33, and both ends of the fixing pin 33 are placed in the second pin holes 32. When adopting this structure, external liquid can penetrate into the interior of the housing 3 from the first pin hole 414 and the second pin holes 32. It can be seen that the interior of the housing 3 cannot achieve the purpose of waterproofing, thereby affecting the service life and the applicability of the use environment of the LED lamp 42, the control assembly 5, and the battery 43 inside the housing 3.

[0005] In view of this, the present invention discloses a waterproof pull handle, which includes a housing and an insertion part that can be inserted into the housing; the insertion part includes an upper insertion piece and a lower insertion piece that can be relatively opened up and down, and a content cavity defined jointly by the upper insertion piece and the lower insertion piece is arranged in the insertion part. The upper insertion piece and the lower insertion piece can be hermetically connected so that the content cavity has water tightness; a plugging cavity extending in the front-rear direction is arranged in the housing, and an orifice penetrating the plugging cavity is arranged at at least one side position in the front-rear direction of the housing. At least part of the insertion part can be inserted into the plugging cavity from the orifice; when at least part of the insertion part is inserted into the plugging cavity, the cavity wall of the plugging cavity restricts the upper insertion piece and the lower insertion piece in the up-down direction so that the upper insertion piece and the lower insertion piece are kept in sealed connection under the force in the up-down direction.

[0006] Wherein, the waterproof pull handle can be used as a pull tab of the zipper, and can also be used as an ornament connected to products such as zippers, suitcases, clothes, necklaces, etc. The content cavity can be used to accommodate electronic components or other objects according to design or use requirements. For example, the electronic component is an induction module, and the induction module can be used to sense opening a door or turning on a light, etc.; or the electronic component is a tracking module, and the tracking module can be used to track the position of the pull handle carrier, especially suitable for children and the elderly; or the electronic component is a lighting module, and the lighting module can be used for lighting, warning and other functions.

[0007] Wherein, a connecting rope can be arranged on the housing or the insertion part to hang the pull handle on the zipper or the pull handle application article, or a combination hole for external connection can be directly arranged on the housing or the insertion part.

[0008] Wherein, the insertion part includes an upper insertion piece and a lower insertion piece that can be relatively opened up and down, which defines that the upper insertion piece and the lower insertion piece are structures that can be combined and relatively opened. The upper insertion piece and the lower insertion piece can be two completely independent insertion pieces, or can be a structure connected together at one side end, such as hinged together.

[0009] Among them, a content cavity defined jointly by the upper insertion piece and the lower insertion piece is arranged in the insertion part. It is defined that the content cavity is a space formed by the joint definition when the upper insertion piece and the lower insertion piece are combined together. When the upper insertion piece and the lower insertion piece are opened relatively, the content cavity can be opened and can have a relatively large opening, so that it is convenient to put in or take out objects such as electronic components at this time. The content cavity can be formed by the open cavity arranged on the upper insertion piece and the upper surface of the lower insertion piece, or can be formed by the open cavity arranged on the lower insertion piece and the lower surface of the upper insertion piece, or can be jointly formed by the open cavity arranged on the lower insertion piece and the open cavity arranged on the upper insertion piece, or in other forms jointly defined by the upper insertion piece and the lower insertion piece; Therefore, it can be seen that a part of the cavity wall of the content cavity is associated with the lower insertion piece, and the other part of the cavity wall is associated with the upper insertion piece.

[0010] Among them, the upper insertion piece and the lower insertion piece can be hermetically connected so that the content cavity has water tightness. It is defined that when the upper insertion piece and the lower insertion piece are combined in the up-down direction, external liquids such as water and oil cannot easily enter the content cavity. If there is liquid in the content cavity, the liquid in the content cavity cannot easily flow out either. Among them, the content cavity has water tightness, which means that as long as the waterproof pull handle can be guaranteed to be used in the daily air pressure environment, for example, the waterproof pull handle can normally contact sweat, rainwater in rainy days and cleaning water during the cleaning process during use, it has already enabled the user to live very comfortably and achieved the water tightness requirement hoped for by this patent.

[0011] Among them, a plugging cavity extending in the front-back direction is arranged in the shell, and an orifice penetrating the plugging cavity is arranged at at least one side position in the front-back direction of the shell, and the defined front-back direction is a relative orientation.

[0012] Among them, when at least part of the insertion part is inserted into the plugging cavity, the cavity wall of the plugging cavity restricts the upper insertion piece and the lower insertion piece in the up-down direction so that the upper insertion piece and the lower insertion piece are stressed in the up-down direction to maintain a sealed connection. It is defined that the upper insertion piece and the lower insertion piece are stressed in the up-down direction by being inserted into the plugging cavity, and the sealed connection between the upper insertion piece and the lower insertion piece can be ensured through the stress in the up-down direction. The cavity wall of the plugging cavity can be provided with a stepped structure above and below the insertion part to clamp the insertion part up and down, or can be provided with springs, soft gaskets or other structures connected to the cavity wall of the plugging cavity to achieve the purpose of pressing and clamping the insertion part up and down, as long as it can make the upper insertion piece and the lower insertion piece be stressed in the up-down direction to maintain a sealed connection.

[0013] Compared with the prior art, the present invention has the following main beneficial effects:

[0014] First, the present invention defines the content cavity jointly by the upper insert piece and the lower insert piece that can be opened relatively up and down. Thus, when the upper insert piece and the lower insert piece are in a relatively open state, it is convenient to place an object that needs to be kept water-sealed, such as an electronic component, in the cavity that defines the content cavity. Then, the upper insert piece and the lower insert piece are covered so that the electronic component is accommodated in the closed content cavity. Second, since a sealing structure is arranged between the upper insert piece and the lower insert piece, and a force in the up-and-down direction is applied to the upper insert piece and the lower insert piece through the housing or a component attached thereto to keep the upper insert piece and the lower insert piece in sealed connection, thereby ensuring that the content cavity maintains water tightness.

[0015] A further technical solution may be that the present invention enhances the sealed connection between the upper insert piece and the lower insert piece through the following two solutions:

[0016] The first solution is that a sealing ring surrounding the content cavity is arranged between the upper insert piece and the lower insert piece, and the upper insert piece and the lower insert piece are hermetically connected by means of the sealing ring. Wherein, the sealing ring surrounds the content cavity so that the content cavity is completely enclosed within the sealing ring. This solution realizes the sealed connection between the two by arranging a sealing ring between the upper insert piece and the lower insert piece, and has a simple structure and good sealing performance.

[0017] Among them, the upper insert piece or the lower insert piece may be provided with a sealing groove for accommodating the sealing ring. During installation, the sealing ring is placed at the sealing groove, and then the other insert piece is covered, and the sealing ring is pressed by the surface of the other insert piece, thereby realizing the water tightness of the content cavity. Of course, the present invention does not exclude arranging opposite sealing grooves on both the upper insert piece and the lower insert piece, or directly arranging the sealing ring between the flat surfaces of the upper insert piece and the lower insert piece.

[0018] The second solution is that a concave-convex tooth groove structure surrounding the content cavity is arranged between the upper insert piece and the lower insert piece. The concave-convex tooth groove structure includes protruding teeth and recessed grooves adapted to the protruding teeth, and the upper insert piece and the lower insert piece are hermetically connected by a connection structure in which the protruding teeth are inserted into the recessed grooves and can be tightly combined. This solution enhances the sealing performance of the content cavity through the concave-convex tooth groove structure. At this time, at least the protruding teeth are made of a material with a certain elasticity.

[0019] As a further technical solution of the second above-mentioned solution, a gasket may also be provided between the protruding teeth and the recessed grooves. In this way, the sealing performance of the concave-convex tooth groove structure is enhanced by the gasket. Among them, the gasket may be placed at the position between the end of the protruding tooth and the bottom of the recessed groove, or may be sleeved on the protruding tooth.

[0020] As a further technical solution of the second above-mentioned solution, the cross-sections of the protruding teeth and the recessed grooves are respectively trapezoidal or conical. In this way, the sealing performance of the concave-convex tooth groove structure is enhanced by the trapezoidal or conical structure.

[0021] Among them, when there is no sealing ring and the concave-convex tooth groove structure, the upper insert piece and the lower insert piece can also be tightly pressed under the action of the up-and-down force of the housing to maintain a sealed connection.

[0022] For the convenience of use at night, the waterproof pull handle of the present invention has a lighting function. Specifically, a light-transmitting part that allows the light in the content cavity to transmit through is provided on the upper insert piece or the lower insert piece, and a lighting device that can emit light is provided in the content cavity. In this way, the light emitted by the lighting device can be transmitted through the light-transmitting part, so that the waterproof pull handle has a lighting function, which can indicate the position of the waterproof pull handle at night when in use, and can also warn others. Of course, the housing does not affect the light transmission of the lighting device. For example, an opening such as the cavity opening can be provided in the area of the housing corresponding to the light-transmitting part, or at least the housing in this area is made of a light-transmitting material.

[0023] A further technical solution may also be that a photosensitive device for picking up external natural light and transmitting a light induction signal to a controller is further provided in the content cavity, and the controller is used to respond to the light induction signal of the photosensitive device and control the lighting device. In this way, the lighting device is automatically lit in low light conditions through the photosensitive device. Of course, the lighting device of the present invention can also be controlled to emit light by a switch. For example, the lighting device is controlled to work by pressing a switch, and the area of the insertion part corresponding to the pressing switch is designed to be a structure capable of being pressed or is made of a material with a certain elasticity.

[0024] A further technical solution may also be that a wedge-shaped protrusion is provided on the upper surface and / or the lower surface of the insertion part, and the wedge-shaped protrusion inclines away from the insertion part along the insertion direction of the insertion part. When at least part of the insertion part is inserted into the insertion cavity, the wedge-shaped protrusion abuts against the cavity wall of the insertion cavity. In this way, under the action of the wedge-shaped protrusion, the insertion part can further enhance the pressing effect between the upper insert piece and the lower insert piece, thereby improving the reliability of the sealed connection between the upper insert piece and the lower insert piece.

[0025] Correspondingly, the present invention also discloses a zipper, which includes a pair of tape strips, on which teeth are arranged, and further includes a slider for engaging or disengaging the teeth on the pair of tape strips, and also includes the waterproof pull handle of the present invention. The waterproof pull handle is connected to the slider for pulling the slider to move. Similarly, the zipper at least has the performance and effects of the waterproof pull handle described above.

[0026] Among them, the waterproof pull handle can be directly used as the tab of the slider. At this time, a pull lug is provided on the slider, and a coupling hole for coupling with the pull lug is provided on the waterproof pull handle. The coupling hole is provided at one end of the housing or the insertion part. Of course, the waterproof pull handle can also be connected to the pull lug through a connecting rope. The waterproof pull handle can also be used as a pulling accessory for the zipper, as described below.

[0027] A further technical solution may be that a tab is provided on the slider, and the waterproof pull handle is connected to the tab. This facilitates the user to replace the waterproof pull handle.

[0028] Due to the above characteristics and advantages of the present invention, it can be used in the waterproof pull handle and the zipper. Description of the Drawings

[0039] Next, in conjunction with Figures 1 to 10 The waterproof pull handle 100 applying the technical solution of the present invention and the structure of a zipper applying the waterproof pull handle 100 will be further described. The waterproof pull handle 100 of the present invention can be used as a pull handle of the slider 5, and can also be used as an ornament connected to products such as zippers, luggage, clothing, necklaces, etc.

[0040] As Figures 1 to 4 shown, the waterproof pull handle 100 includes a housing 1 and an insertion part 2 that can be inserted into the housing 1; the insertion part 2 includes an upper insertion piece 21 and a lower insertion piece 22, the upper insertion piece 21 and the lower insertion piece 22 are arranged up and down, and a structure member that can be relatively opened is between the upper insertion piece 21 and the lower insertion piece 22, that is, the upper insertion piece 21 and the lower insertion piece 22 are two completely independent insertion pieces up and down, as Figure 2 shown; in another embodiment, as Figures 5 to 9 shown, the upper insertion piece 21 and the lower insertion piece 22 are structures hinged together at one side end. It can also be that the upper insertion piece 21 and the lower insertion piece 22 are connected together at one side end through a thin bendable connecting plate body. Of course, the upper insertion piece 21 and the lower insertion piece 22 can also be designed into other structures that can meet the requirements of the present invention according to needs.

[0041] An inner cavity 20 defined jointly by the upper insertion piece 21 and the lower insertion piece 22 is provided in the insertion part 2, and the upper insertion piece 21 and the lower insertion piece 22 can be hermetically connected so that the inner cavity 20 has water tightness. The inner cavity 20 is a space formed jointly by the upper insertion piece 21 and the lower insertion piece 22 when they are combined. When the upper insertion piece 21 and the lower insertion piece 22 are relatively opened, the inner cavity 20 has a relatively large opening, so that it is convenient to put in or take out objects such as electronic components at this time. Specifically, as Figure 2 and Figure 3As shown, an upper insertion piece 21 is provided with an upper opening cavity 201, and a lower insertion piece 22 is provided with a lower opening cavity 202 disposed opposite to the upper opening cavity 201. The content cavity 20 is formed by jointly defining by the upper opening cavity 201 and the lower opening cavity 202; in other embodiments, the content cavity 20 may be formed by the upper opening cavity 201 provided on the upper insertion piece 21 and the upper surface of the lower insertion piece 22, or may be formed by the lower opening cavity 202 provided on the lower insertion piece 22 and the lower surface of the upper insertion piece 21, or other forms jointly defined by the upper insertion piece 21 and the lower insertion piece 22; thus, it can be seen that a part of the cavity wall of the content cavity 20 is associated with the lower insertion piece 22, and another part of the cavity wall is associated with the upper insertion piece 21.

[0042] Among them, the content cavity 20 can be used to accommodate electronic components (not shown in the drawings) or other objects according to design or usage requirements. For example, the electronic component is an induction module, and the induction module can be used to sense door opening or light turning on, etc.; or the electronic component is a tracking module, and the tracking module can be used to track the position of the handle carrier, especially suitable for children and the elderly; or the electronic component is a lighting module, and the lighting module can be used for lighting, warning and other functions.

[0043] A plugging cavity 11 extending in the front-rear direction is provided in the housing 1. An orifice 12 communicating with the plugging cavity 11 is provided at a side position in the front-rear direction of the housing 1. At least a part of the insertion portion 2 can be inserted into the plugging cavity 11 from the orifice 12. A cover can be provided at the orifice 12 to cover the orifice 12. When the cover structure is adopted, the cover can be used as a part for pressing the insertion portion 2. Secondly, an auxiliary orifice 13 communicating with the plugging cavity 11 is further provided at another side position in the front-rear direction of the housing 1. The auxiliary orifice 13 corresponds to the orifice 12 in the front-rear direction. The auxiliary orifice 13 can be used to receive the protrusion of the head of a part of the insertion portion 2, or to allow other accessories connected to the head of the insertion portion 2, such as a connecting rope, to extend out of the plugging cavity 11 through the auxiliary orifice 13. An anti-disengagement step surface 14 is provided at a position of the plugging cavity 11 near the auxiliary orifice 13. The anti-disengagement step surface 14 faces the orifice 12. A clamping step portion 25 adapted to the anti-disengagement step surface is formed at the head of the insertion portion 12. During assembly, the insertion portion 2 is inserted into the plugging cavity 11 until the clamping step portion 25 abuts against the anti-disengagement step surface 14, so as to prevent the insertion portion 2 from disengaging from the auxiliary orifice 13. In another embodiment, orifices 12 communicating with the plugging cavity 11 are provided at both side positions in the front-rear direction of the housing 1. At this time, the insertion portion 2 can be inserted into the plugging cavity 11 from any one of the two orifices 12.

[0044] When at least a part of the insertion portion 2 is inserted into the plugging cavity 11, the cavity wall of the plugging cavity 11 restricts the upper insertion piece 21 and the lower insertion piece 22 in the up-down direction, so that the upper insertion piece 21 and the lower insertion piece 22 are stressed in the up-down direction to maintain a sealed connection. In the present invention, the upper insertion piece 21 and the lower insertion piece 22 are stressed in the up-down direction by being inserted into the plugging cavity 11, and the sealed connection between the upper insertion piece 21 and the lower insertion piece 22 is ensured by the stress in the up-down direction. Specifically, a stepped structure is provided above and below the insertion portion 2 on the cavity wall of the plugging cavity 11 to clamp the insertion portion 2 up and down (which is actually a tight fit structure). In other embodiments, springs, soft gaskets or other structures connected to the cavity wall of the plugging cavity 11 can also be provided to achieve the purpose of pressing and clamping the insertion portion 2 up and down, as long as the upper insertion piece 21 and the lower insertion piece 22 can be stressed in the up-down direction to maintain a sealed connection.

[0045] Among them, the front-rear direction of the housing 1 defined above is a relative orientation, which is specifically the front-rear orientation marked in the attached Figure 1 drawing in this embodiment. In another embodiment, the front-rear direction of the housing 1 can also be the same as that in the attachedFigure 1 The direction perpendicular to the indicated orientation or other orientations that can meet the requirements.

[0046] When the waterproof pull handle 100 of the present invention is adopted, after the upper insert piece 21 and the lower insert piece 22 are combined in the up-and-down direction, external liquids such as water and oil cannot easily enter the content cavity 20. If there is liquid in the content cavity 20, the liquid in the content cavity 20 cannot easily flow out either. Among them, the content cavity 20 has water tightness, which means that as long as the waterproof pull handle 100 can be guaranteed to be used in the daily air pressure environment, for example, the waterproof pull handle 100 can normally come into contact with sweat, rainwater on rainy days, and cleaning water during the cleaning process during use, it has already enabled the user to live very comfortably and achieved the water tightness requirement hoped for by this patent.

[0047] In summary, the present invention jointly defines the content cavity 20 by the upper insert piece 21 and the lower insert piece 22 that can be opened relatively up and down, so that when the upper insert piece 21 and the lower insert piece 22 are in a relatively open state, objects that need to be kept water-sealed, such as electronic components, can be placed in the cavity that defines the content cavity 20, and then the upper insert piece 21 and the lower insert piece 22 are closed so that the electronic components are accommodated in the closed content cavity 20; in addition, since a sealing structure is arranged between the upper insert piece 21 and the lower insert piece 22, and an up-and-down direction force is applied to the upper insert piece 21 and the lower insert piece 22 through the housing 1 or the components attached thereto to keep the upper insert piece 21 and the lower insert piece 22 in sealed connection, thereby ensuring that the content cavity 20 maintains water tightness.

[0048] It should be noted that the present invention preferably ensures the sealed connection between the upper insert piece 21 and the lower insert piece 22 through the following two schemes:

[0049] The first sealing scheme is as shown in the appendix Figure 3 A concave-convex tooth groove structure surrounding the content cavity 20 is provided between the upper insert piece 21 and the lower insert piece 22. The concave-convex tooth groove structure includes a protruding tooth 31 and a concave groove 32 adapted to the protruding tooth 31. The upper insert piece 21 and the lower insert piece 22 are hermetically connected by means of a connection structure in which the protruding tooth 31 is inserted into the concave groove 32 and can be tightly combined. This scheme enhances the sealing performance of the content cavity 20 through the concave-convex tooth groove structure. At this time, at least the protruding tooth 31 is made of a material with a certain elasticity.

[0050] The present invention can also adopt the following setting method to further enhance the sealing between the concave-convex tooth groove structures:

[0051] In the first method, a gasket (not shown in the drawings) is further provided between the protruding teeth 31 and the recessed grooves 32. Wherein, the gasket can be placed at the position between the end of the protruding teeth 31 and the bottom of the recessed grooves 32, or can be sleeved on the protruding teeth 31.

[0052] In the second method, the cross-sections of the protruding teeth 31 and the recessed grooves 32 are respectively trapezoidal or conical. In this way, the sealing performance of the concave-convex tooth groove structure is enhanced through the trapezoidal or conical structure.

[0053] In the third method, a conical protrusion is provided at the bottom of the recessed groove 32, and a conical groove adapted to the conical tooth is provided on the end face of the protruding tooth 31.

[0054] The second sealing solution, as Figure 8 and Figure 9 shown, Figure 8 and Figure 9 shows the structure of the fourth embodiment of the waterproof pull handle 100 of the present invention. In this method, the sealing performance between the upper insertion piece 21 and the lower insertion piece 22 is enhanced through the sealing ring 4. Specifically, a sealing ring 4 surrounding the content cavity 20 is provided between the upper insertion piece 21 and the lower insertion piece 22, and the upper insertion piece 21 and the lower insertion piece 22 are hermetically connected by means of the sealing ring 4. Wherein, the sealing ring 4 surrounds the content cavity 20 so that the content cavity 20 is completely enclosed within the sealing ring 4. This solution realizes the sealing connection between the upper insertion piece 21 and the lower insertion piece 22 by providing the sealing ring 4 between them, and has a simple structure and good sealing performance.

[0055] Wherein, a sealing groove 23 is provided on the upper insertion piece 21. During installation, the sealing ring 4 is placed at the sealing groove 23, and then the upper insertion piece 21 and the lower insertion piece 22 are covered. The sealing ring 4 is pressed by the surface of the lower insertion piece 22, thereby realizing the water tightness of the content cavity 20. In other embodiments, the sealing groove 23 can also be provided on the lower insertion piece 22, or sealing grooves 23 can be provided on both the upper insertion piece 21 and the lower insertion piece 22, or the sealing ring 4 can be directly provided between the flat surfaces of the upper insertion piece 21 and the lower insertion piece 22.

[0056] For easy use at night, the waterproof pull handle 100 of the present invention has a lighting function. Specifically, a light-transmitting portion (not shown in the drawings) that allows the light in the content cavity 20 to transmit through is provided on the upper insertion piece 21 or the lower insertion piece 22, and a light-emitting device that can emit light is provided in the content cavity 20 (not shown in the drawings). In this way, the light emitted by the light-emitting device can be transmitted through the light-transmitting portion, so that the waterproof pull handle 100 has a lighting function, which can indicate the position of the waterproof pull handle 100 at night and can also warn others. Of course, the housing 1 does not prevent the light of the light-emitting device from transmitting through. For example, an opening such as the cavity opening 12 can be provided in the area of the housing 1 corresponding to the light-transmitting portion, or at least this area of the housing 1 is made of a light-transmitting material.

[0057] Furthermore, a photosensitive device (not shown in the drawings) for picking up external natural light and transmitting a light induction signal to a controller is also provided in the content cavity 20, and the controller is used to respond to the light induction signal of the photosensitive device and control the light-emitting device. In this way, the light-emitting device is automatically turned on in low-light conditions through the photosensitive device. Of course, the light-emitting device of the present invention can also be controlled to emit light by vibration or a switch. For example, the light-emitting device is controlled to work by pressing a switch, and the area of the insertion portion 2 corresponding to the pressing switch is designed to be a structure capable of being pressed or is made of a material with a certain elasticity.

[0058] To enhance the tightness of the combination of the upper insertion piece 21 and the lower insertion piece 22, as Figure 5 and Figure 7 shown, a wedge-shaped protrusion 24 is provided on the upper surface of the insertion portion 2, and the wedge-shaped protrusion 24 inclines away from the insertion portion 2 along the insertion direction of the insertion portion 2. When at least a part of the insertion portion 2 is inserted into the insertion cavity 11, the wedge-shaped protrusion 24 abuts against the cavity wall of the insertion cavity 11. In this way, under the action of the wedge-shaped protrusion 24, the insertion portion 2 can further enhance the pressing effect between the upper insertion piece 21 and the lower insertion piece 22, thereby improving the reliability of the sealed connection between the upper insertion piece 21 and the lower insertion piece 22. As Figure 7 shown, the wedge-shaped protrusion 24 can also be provided on the lower surface of the insertion portion 2, or the wedge-shaped protrusion 24 is provided on both the upper and lower surfaces of the insertion portion 2.

[0059] As Figure 10As shown, the present invention also discloses a zipper, which includes a pair of chain tapes (not shown in the drawings), a slider 5, and the waterproof pull handle 100 of the present invention. Chain teeth are arranged on the chain tapes (not shown in the drawings). The slider 5 is used to engage or disengage the chain teeth on the pair of chain tapes.
