Description

Technical Field

[0001] This utility model relates to welding auxiliary tools, and in particular to a replaceable connector airbag for a solder blower. Background Technology

[0002] With the development of technology, people have more and more opportunities to come into contact with circuits. Circuits are made by soldering electrical components onto circuit boards. If some components on the circuit board are damaged, people need to replace the faulty components. The first step in removing components from the circuit board is to remove the solder from the component pins.

[0003] Common desoldering methods include desoldering pumps, desoldering ribbons, or hollow needles. Newer solutions include desoldering blowers, which remove solder from electrical component pins by blowing air. These blowers require different sized hollow needles for different pin sizes. Since the hollow needles can be hollow tubular or Luer-connected, different needles need to connect to the blower's air bladder. Because the air bladder is made of a flexible, soft material, frequent compression can cause unstable connections between the needle and bladder, leading to leaks or breakage, compromising the air pressure and reducing desoldering efficiency. Existing desoldering blowers cannot guarantee a stable connection between the needle and air bladder, and the air bladder is not compatible with multiple sizes of hollow needles. Therefore, different air bladders with different connection ports are needed for hollow needles of different structures and sizes. Moreover, in the existing technology, the air bladder of the solder blower is made of a one-piece flexible material. When the bladder is squeezed by external force, the pressure increases. When the bladder is squeezed, the air outlet is driven to undergo elastic deformation. In addition, the air outlet and the corresponding mating object will also undergo elastic deformation due to interference fit. Under the long-term action of the above two elastic deformation forces, the air outlet is prone to plastic deformation, resulting in air leakage or tearing. Summary of the Invention

[0004] The purpose of this invention is to address the problems in existing solder blowers, such as the inability to guarantee a stable connection between the needle and the air bladder, the susceptibility of the air outlet to plastic deformation leading to leakage or tearing, and the incompatibility of the air outlet with various sizes of corresponding mating parts. This invention provides a replaceable air bladder for solder blowers. By incorporating a locking support, the air outlet is sized and locked, allowing for a wider range of mating part sizes and shapes to be accommodated. Simultaneously, the connection between the air outlet and the mating part is more stable and has better sealing. A rigid support locking ring surrounds the air outlet, increasing its rigidity and thus reducing the probability of damage from long-term elastic deformation.

[0005] To achieve the above objectives, this utility model provides the following solution: a replaceable connector airbag for a solder blower, characterized in that it includes an airbag portion and a locking support portion. The airbag portion consists of a bag body and an air outlet, and the airbag portion is made of an elastic material. The locking support portion consists of a locking device and a support ring, and the locking support portion locks and supports the air outlet by a ring-locking method.

[0006] Furthermore, the locking support is a threaded locking structure, the locking device is a self-locking screw structure, the support ring is a perforated strip, one end of the perforated strip is connected to one end of the self-locking screw structure, and the hole at the other end of the perforated strip engages with the thread of the self-locking screw structure.

[0007] Furthermore, the locking support is a deformation locking structure, the locking device is a deformation locking head, the support ring is a locking ring, the locking support has at least one deformation locking head, and the deformation locking head and the locking ring are connected in series to form a ring.

[0008] Furthermore, the locking support is a top-tightening locking structure, the locking device is a top-tightening screw, the support ring is a nut pull ring, and the top-tightening screw engages with the nut pull ring and self-locks.

[0009] Furthermore, the locking support is a cable tie type locking structure, the locking device is a self-locking clip, the support ring is a locking rack, and the self-locking clip meshes with the locking rack and self-locks.

[0010] Furthermore, the locking support is a cam-type locking structure, the locking device is a cam lock head, the support ring is a lock ring, and the cam lock head squeezes and locks the lock ring by eccentric rotation.

[0011] Furthermore, the locking support is an elastic locking structure, the locking device is a compression head, the support ring is an elastic ring, and the compression head and the elastic ring are connected in series to form a ring.

[0012] Furthermore, the airbag portion is provided with a sleeve, and there is at least one sleeve. The sleeve can be embedded in the air outlet, and the sleeve is locked to the air outlet by the locking support portion.

[0013] Furthermore, the airbag part is provided with a threaded connector, which is a hollow tubular structure. One end of the threaded connector is embedded in the air outlet, and the threaded connector is locked to the air outlet by the locking support part. The other end of the threaded connector is provided with internal or external threads.

[0014] Furthermore, the airbag part is provided with a Luer connector, which is embedded in the air outlet. The Luer connector is locked to the air outlet by the locking support part, and the Luer connector can be quickly connected to a hollow needle with a Luer connector.

[0015] The beneficial effects of this utility model are as follows: 1. The locking support of the replaceable connector airbag for solder blowers in this solution plays a role in adjusting and locking the size of the air outlet interface, making the air outlet interface adaptable to a wider range of corresponding mating interface sizes and shapes. Simultaneously, the connection between the air outlet connector and the corresponding mating interface is more stable and has better sealing. When the inner diameter of the air outlet interface (without deformation) is circular and its diameter is n mm, due to the elastic material of the air outlet interface, under the action of elastic deformation, the air outlet interface can directly install cylindrical mating interface with a diameter of n~(n+2) mm. However, if the cross-section of the mating interface is circular and its diameter is less than n mm, the air outlet interface and the mating interface cannot be directly and securely connected; if the cross-section of the mating interface is polygonal and its circumscribed circle is less than n mm, the air outlet interface and the mating interface may not be able to be directly and securely connected. This solution adds a locking support, under the locking pressure of the locking support, the air outlet interface can achieve a secure and sealed connection with mating interfaces with a circular cross-section and a diameter less than n mm or a polygonal cross-section and a circumscribed circle diameter less than n mm. 2. In existing solder blowers, the air bladder is made of a single piece of flexible material. External force compressing the bladder increases pressure, causing the air outlet to undergo elastic deformation. Additionally, the interference fit between the air outlet and its mating parts also leads to elastic deformation. Under prolonged exposure to these two elastic deformation forces, the air outlet is prone to plastic deformation, resulting in air leakage or tearing. This solution incorporates a support locking ring surrounding the air outlet, increasing its rigidity and reducing the probability of damage from long-term elastic deformation.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings. (See attached drawings.) Figures 1-10 . Example 1

[0018] like Figure 1 As shown, a replaceable connector airbag for a solder blower is characterized by comprising an airbag part 1 and a locking support part 2. The airbag part 1 consists of a bag body 101 and an air outlet 102, and the airbag part 1 is made of an elastic material. The locking support part 2 consists of a locking device 21 and a support ring 22, and the locking support part 2 locks and supports the air outlet 102 by a ring locking method.

[0019] like Figure 2 As shown, the locking support part 2 is a threaded locking structure, the locking device 21 is a self-locking screw structure 201, and the support ring 22 is a perforated strip 202. One end of the perforated strip 202 is fixedly connected to one end of the self-locking screw structure 201, and the hole at the other end of the perforated strip 202 engages with the thread of the self-locking screw structure 201. When the user rotates the self-locking screw structure 201, the thread of the self-locking screw structure 201 will drive the perforated strip 202 to lock or loosen the air outlet 102. The locking support part 2 is a ring structure, and the width of the perforated strip 202 along the axial direction of the locking support part 2 is 8mm. When the perforated strip 202 locks the air outlet 102, the perforated strip 202 can support the flexible material air outlet 102.

[0020] likeFigure 3 As shown, the inner diameter of the vent 102 is 9mm. Since the vent 102 is made of an elastic material, it can undergo elastic deformation. Therefore, the vent 102 can directly connect to cylindrical interfaces with an outer diameter of 9-11mm. However, it cannot directly connect to cylindrical interfaces with a diameter less than 9mm, or to polygonal interfaces with an outer circle diameter less than 9mm. When the vent 102 is connected to a cylindrical interface with a diameter less than 9mm, a perforated strip 202 surrounds the outside of the vent 102, providing support. The self-locking screw structure 201 locks the perforated strip 202, thereby compressing the vent 102 until its inner side conforms to the size and shape of the interface, achieving stability and sealing when connecting the vent 102 to interfaces of different sizes and shapes. A1 is a coarse cylindrical hollow needle with an outer diameter of 8mm, and A2 is a medium-coarse cylindrical hollow needle with an outer diameter of 6mm. Without the locking support 2, neither A1 nor A2 can be installed on the air outlet 102 of the airbag part 1. After the locking support 2 is installed, A1 and A2 can be stably and sealed on the air outlet 102 of the airbag part 1. Example 2

[0021] like Figure 1 As shown, a replaceable connector airbag for a solder blower is characterized by comprising an airbag part 1 and a locking support part 2. The airbag part 1 consists of a bag body 101 and an air outlet 102, and the airbag part 1 is made of an elastic material. The locking support part 2 consists of a locking device 21 and a support ring 22, and the locking support part 2 locks and supports the air outlet 102 by a ring locking method.

[0022] like Figure 2 As shown, the locking support part 2 is a threaded locking structure, the locking device 21 is a self-locking screw structure 201, and the support ring 22 is a perforated strip 202. One end of the perforated strip 202 is connected to one end of the self-locking screw structure 201, and the hole at the other end of the perforated strip 202 engages with the thread of the self-locking screw structure 201. When the user rotates the self-locking screw structure 201, the thread of the self-locking screw structure 201 will drive the perforated strip 202 to lock or loosen the air outlet 102. The locking support part 2 is a ring structure, and the width of the perforated strip 202 along the axial direction of the locking support part 2 is 8mm. When the perforated strip 202 locks the air outlet 102, the perforated strip 202 can support the flexible material air outlet 102.

[0023] like Figure 3As shown, the air outlet 102 has an inner diameter of 9mm and an outer diameter of 15mm. Since the air outlet 102 is made of an elastic material, it can undergo elastic deformation. Therefore, the air outlet 102 can directly connect to cylindrical interfaces with an outer diameter of 9-11mm, but it cannot directly connect to cylindrical interfaces with a diameter less than 9mm, or to polygonal interfaces with an outer circle diameter less than 9mm. When the air outlet 102 is connected to a cylindrical interface with a diameter less than 9mm, a perforated strip 202 surrounds the outer side of the air outlet 102 to provide support. The self-locking screw structure 201 locks the perforated strip 202, thereby compressing the air outlet 102 until its inner side conforms to the size and shape of the interface, achieving stability and sealing when connecting the air outlet 102 to interfaces of different sizes and shapes. A1 is a coarse cylindrical hollow needle with an outer diameter of 8mm, and A2 is a medium-coarse cylindrical hollow needle with an outer diameter of 6mm. Without the locking support 2, neither A1 nor A2 can be installed on the air outlet 102 of the airbag part 1. After the locking support 2 is installed, A1 and A2 can be stably and sealed on the air outlet 102 of the airbag part 1.

[0024] like Figure 4 As shown, the airbag part 1 is provided with a sleeve 103. There are three sleeves 103 in a set. The sleeves 103 can be embedded in the air outlet 102. The sleeves 103 are locked to the air outlet 102 by the locking support part 2. When the outer diameter of the air outlet 102 is less than 4mm when connecting to the docking interface, it will be squeezed by the locking support part 2 until the inner diameter of the air outlet 102 is 4mm (the normal inner diameter of the air outlet 102 is 9mm). Excessive deformation over a long period of time will reduce the life of the air outlet 102. Therefore, when the outer diameter of the docking interface is less than 6mm, the air outlet 102 needs to be fitted with a sleeve 103 to reduce the deformation of the air outlet 102 when connecting to small-sized docking interfaces. A1 is a thick cylindrical hollow needle with an outer diameter of 8mm, and A3 is a thin cylindrical hollow needle with an outer diameter of 4mm. The inner diameter of the sleeve 103 is 4mm and the outer diameter is 8mm. After adding the sleeve 103, it is fixed and sealed by the support locking part 2. The deformation of the air outlet 102 is only compressed from an inner diameter of 9mm to about 8mm. This deformation range is within the normal range, so it can be used for a long time. Example 3

[0025] like Figure 1 As shown, a replaceable connector airbag for a solder blower is characterized by comprising an airbag part 1 and a locking support part 2. The airbag part 1 consists of a bag body 101 and an air outlet 102, and the airbag part 1 is made of an elastic material. The locking support part 2 consists of a locking device 21 and a support ring 22, and the locking support part 2 locks and supports the air outlet 102 by a ring locking method.

[0026] likeFigure 5 As shown, the locking support part 2 is a deformation-type locking structure. The locking device 21 is a deformation locking head 203, and the support ring 22 is a locking ring 204. The locking support part 2 has a deformation locking head 203, which is connected in series with the locking ring 204 to form a ring 20. When the tightening head 203 is compressed and deformed, the two ends of the tightening head 203 will move closer to each other, and the diameter of the inner circle of the ring 20 will decrease, thereby locking the air outlet 102. If it is necessary to replace the connecting object of the air outlet 102, the user can cut off the locking support part 2, then replace the connecting object of the air outlet 102, and then replace the new locking support part 2 to lock and support the air outlet 102.

[0027] like Figure 6 As shown, the airbag part 1 is equipped with a threaded connector 104, which is a hollow tubular structure. One end of the threaded connector 104 is embedded in the air outlet 102, and the threaded connector 104 is locked to the air outlet 102 by the locking support part 2. The other end of the threaded connector 104 is provided with internal or external threads. The threaded connector 104 has an M6 internal thread. B1 is a coarse-threaded hollow needle with an M6 external thread at one end and a hollow tube with an inner diameter of 2mm at the other end. B2 is a fine-threaded hollow needle with an M6 external thread at one end and a hollow tube with an inner diameter of 1mm at the other end. Under the action of the locking support part 2, after the airbag part 1 is fixedly and sealed to the threaded connector 104, the user can quickly replace hollow needles of the same thread specification (M6) with different inner diameters (2mm or 1mm) to suit different usage scenarios. Example 4

[0028] like Figure 1 As shown, a replaceable connector airbag for a solder blower is characterized by comprising an airbag part 1 and a locking support part 2. The airbag part 1 consists of a bag body 101 and an air outlet 102, and the airbag part 1 is made of an elastic material. The locking support part 2 consists of a locking device 21 and a support ring 22, and the locking support part 2 locks and supports the air outlet 102 by a ring locking method.

[0029] like Figure 7 As shown, the locking support part 2 is a top-tightening locking structure. The locking device 21 is a top-tightening screw 205, and the support ring 22 is a nut pull ring 206. The top-tightening screw 205 and the nut pull ring 206 engage and self-lock. The user rotates the top-tightening screw 205 clockwise until the top-tightening screw 205 contacts the air outlet 102. When the top-tightening screw 205 is rotated clockwise further, the nut pull ring 206 will be tightened, thereby squeezing and locking the air outlet 102. Example 5

[0030] like Figure 1As shown, a replaceable connector airbag for a solder blower is characterized by comprising an airbag part 1 and a locking support part 2. The airbag part 1 consists of a bag body 101 and an air outlet 102, and the airbag part 1 is made of an elastic material. The locking support part 2 consists of a locking device 21 and a support ring 22, and the locking support part 2 locks and supports the air outlet 102 by a ring locking method.

[0031] like Figure 8 As shown, the locking support part 2 is a cable tie type locking structure, the locking device 21 is a self-locking clip 207, and the support ring 22 is a locking rack 208. The self-locking clip 207 and the locking rack 208 mesh and self-lock. One end of the locking rack 208 is connected to the self-locking clip 207, and the other end is the protruding end that passes through the self-locking clip 207. Since the tooth profile of the self-locking clip 207 and the locking rack 208 is a one-way self-locking mesh, the protruding end of the locking rack 208 cannot be retracted after passing through the self-locking clip 207. When the user pulls the protruding end of the locking rack 208 through the self-locking clip 207, the ring connected in series with the self-locking clip 207 and the locking rack 208 will shrink, thereby squeezing and locking the air outlet 102. Example 6

[0032] like Figure 1 As shown, a replaceable connector airbag for a solder blower is characterized by comprising an airbag part 1 and a locking support part 2. The airbag part 1 consists of a bag body 101 and an air outlet 102, and the airbag part 1 is made of an elastic material. The locking support part 2 consists of a locking device 21 and a support ring 22, and the locking support part 2 locks and supports the air outlet 102 by a ring locking method.

[0033] like Figure 9 As shown, the locking support part 2 is a cam-type locking structure. The locking device 21 is a cam lock head 209, and the support ring 22 is a locking ring 210. The cam lock head 209 compresses and locks the locking ring 210 by eccentric rotation. The two ends of the locking ring 210 are connected by a screw of the cam lock head 209. One end of the screw is a fastening nut, and the other end is an eccentric cam. The user can adjust the distance between the two ends of the locking ring 210 by rotating the fastening nut or rotating the eccentric cam, thereby adjusting the tightness of the air outlet 102. Example 7

[0034] like Figure 1 As shown, a replaceable connector airbag for a solder blower is characterized by comprising an airbag part 1 and a locking support part 2. The airbag part 1 consists of a bag body 101 and an air outlet 102, and the airbag part 1 is made of an elastic material. The locking support part 2 consists of a locking device 21 and a support ring 22, and the locking support part 2 locks and supports the air outlet 102 by a ring locking method.

[0035] like Figure 10As shown, the locking support part 2 is an elastic locking structure, the locking device 21 is a compression head 211, and the support ring 22 is an elastic ring 212. The compression head 211 and the elastic ring 212 are connected in series to form a ring. When the user presses the compression head 211, the elastic ring 212 is stretched open and its inner circle diameter increases. At this time, the elastic ring 212 does not lock the air outlet 102. When the user releases the compression head 211, the elastic ring 212 contracts under its own elastic force and thus locks the air outlet 102.
