Description

Technical Field

[0001] The utility model relates to a pinhole component defective product blowing conduit connection structure. Background Art

[0002] Pinhole parts blasting is a process for treating defective pinhole parts. Pinhole parts refer to pores or defects generated during the manufacturing process, which may cause quality problems or functional failure of the product. In order to solve these problems, pinhole parts usually need to be blasted.

[0003] Traditional pinhole parts are mostly connected by threaded connections, and both ends of the tube have corresponding threaded structures. By rotating the two tubes, they are connected together.

[0004] Threaded connection requires rotating and tightening the conduit, which requires great strength and effort. At the same time, the installation process requires the use of special tools, which increases the complexity of the installation and is relatively slow. This affects production efficiency. Therefore, a pinhole defective injection conduit connection structure is proposed. Utility Model Content

[0005] The utility model aims to provide a pinhole component defective spray duct connection structure to solve the problem in the above background technology that most of the conventional pinhole component defective spray ducts are connected by threads, the installation is complex and the installation process is relatively slow.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a pinhole defective part blowing conduit connection structure, comprising a nozzle mechanism for blowing pinhole defective parts, an air guide nozzle is arranged above the nozzle mechanism,

[0007] An air pipe is arranged above the nozzle mechanism, and a connecting component is arranged at the air pipe.

[0008] Wherein, the nozzle mechanism and the air pipe are connected to each other through a connecting component to engage the air guide nozzle.

[0009] Preferably, the connection assembly comprises a locking ring plate arranged at the tail end of the trachea, locking cavities are opened on both sides of the locking ring plate, and the locking plate is slidably connected to the inside of the locking cavity.

[0010] Preferably, wing plates for limiting the stroke are provided on both sides of the locking plate.

[0011] Preferably, a guide plate is arranged above the locking plate, and the upper part of the guide plate and the lower part of the locking plate are both rounded.

[0012] Preferably, content grooves for receiving the guide plate are provided on both sides of the inner wall of the locking ring plate, and the content grooves and the guide plate cooperate with each other.

[0013] Preferably, a plurality of sets of locking springs are arranged inside the locking cavity, and the locking springs are located between the locking cavity and the locking plate, so that the locking plate can move elastically in the locking cavity.

[0014] Preferably, a sealing ring is provided on the upper portion of the air guide nozzle, and the sealing ring cooperates with the inner wall of the conduit.

[0015] Preferably, a locking waist groove cooperating with the locking plate is provided on the outer periphery of the middle part of the air guide nozzle, and the upper part of the locking waist groove is rounded.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model adopts a connection structure, a connection assembly and an air guide nozzle, and the air guide nozzle is engaged by the connection assembly, and no longer relies on a complicated threaded connection. This simplifies the installation process and reduces the force and effort required for installation.

[0018] Compared with the traditional threaded connection, which requires the process of rotating and tightening the conduit, the installation process of this connection structure is faster. Through the design of the nozzle mechanism and the air guide nozzle, a more efficient connection operation can be achieved, thereby improving production efficiency.

[0019] The connection assembly includes a locking ring plate and a locking cavity, and the locking plate achieves a locking effect through a sliding connection. This design can improve the stability and convenience of locking.

[0020] Wings that limit the stroke are set on both sides of the locking plate, as well as guide plates and rounded corners on the top. These features help stabilize the position of the locking plate and provide good guidance, thereby enhancing the reliability of the connection. At the same time, the rounded corner design allows the locking plate to be pulled out from the outer periphery of the air guide nozzle through the guiding effect of the rounded corners during later disassembly, thereby improving disassembly efficiency. Compared with threaded connections, this connection structure may be easier to disassemble and can still maintain good performance after multiple connections and disassemblies. This reduces the risk of damage and wear of the connecting parts and improves the reusability of the connection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to solve the problem that most traditional defective pinhole parts blowing ducts are connected by threads, the installation is complex and the installation process is relatively slow, the embodiment of the utility model provides a connection structure for defective pinhole parts blowing ducts. The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 The utility model provides a pinhole defective part blowing conduit connection structure, comprising a nozzle mechanism 1 for blowing pinhole defective parts, an air guide nozzle 2 is arranged above the nozzle mechanism 1, a sealing ring 201 is arranged on the upper part of the air guide nozzle 2, and the sealing ring 201 cooperates with the inner wall of the conduit. A locking waist groove 202 that cooperates with a locking plate 403 is opened on the outer periphery of the middle part of the air guide nozzle 2, and the upper part of the locking waist groove 202 is rounded.

[0028] An air pipe 3 is arranged above the nozzle mechanism 1, and a connecting assembly 4 is arranged at the air pipe 3. The connecting assembly 4 includes a locking ring plate 401 arranged at the tail end of the air pipe 3. Locking cavities 402 are provided on both sides of the locking ring plate 401, and a locking plate 403 is slidably connected inside the locking cavity 402. Wing plates 404 for limiting the stroke are arranged on both sides of the locking plate 403. A guide plate 405 is arranged above the locking plate 403, and the upper part of the guide plate 405 and the lower part of the locking plate 403 are both rounded. Content grooves 406 for accommodating the guide plate 405 are provided on both sides of the inner wall of the locking ring plate 401, and the content grooves 406 and the guide plate 405 cooperate with each other. A plurality of locking springs 407 are disposed inside the locking cavity 402 , and the locking springs 407 are located between the locking cavity 402 and the locking plate 403 , so that the locking plate 403 can move elastically in the locking cavity 402 .

[0029] The nozzle mechanism 1 and the air pipe 3 are connected to each other through a connecting component 4 that engages with the air guide nozzle 2 .

[0030] The working principle of the pinhole defective blow duct connection structure provided by the utility model is as follows: when in use, the locking ring plate 401 is sleeved on the top of the air guide nozzle 2, and then the locking ring plate 401 is pressed downward to make it move down along the air guide nozzle 2. The air guide nozzle 2 squeezes the locking plate 403 through the rounded corners of the lower periphery of the locking plate 403. The locking plate 403 is forced to move toward the locking cavities 402 on both sides, squeezing the locking spring 407. The locking spring 407 is forced to be compressed and deformed until the locking plate 403 and the guide plate 40 5 move to the locking cavity 402 and the inner groove 406 respectively. When the locking ring plate 401 moves to the nozzle mechanism 1, the locking plate 403 is located at the outer periphery of the locking waist groove 202. At this time, the locking spring 407 elastically stretches, driving the locking plate 403 and the guide plate 405 to move out of the locking cavity 402 and the inner groove 406, and snap-fit ​​to the outer periphery of the locking waist groove 202 of the air nozzle. Through the snap-locking effect, the locking ring plate 401 is connected to the air guide nozzle 2, completing the connection between the nozzle mechanism 1 and the air pipe 3.

[0031] When disassembling, pull the locking ring plate 401 upwards so that the rounded corners of the guide plate 405 are pressed and fitted with the rounded corners of the air guide nozzle 2, and squeeze the locking plate 403 into the locking cavity 402, so that the connection between the nozzle mechanism 1 and the air pipe 3 can be released.
