Inflation tool for plastic hose

Abstract

The utility model discloses a plastic hose inflation tool, and particularly relates to the field of plastic hose machining. A fixing ring is fixedly connected to one side of the interior of a connector, and a pair of turnover sealing blocks is arranged on one side of the fixing ring. A positioning mechanism is arranged on the outer side of the inflation pipe. The connector is inserted into the outer side of the inflation tube, during insertion, the outer wall of the inflation tube pushes the two sealing blocks and the corresponding turnover blocks to turn over oppositely with the position of the movable shaft as the circle center, meanwhile, the supporting spring is compressed, and meanwhile the output end of the inflation pump inflates air into the plastic hose body through the inflation tube. After inflation is completed, the connector is pulled out, the supporting spring rebounds to drive the sealing block to turn over oppositely to form a sealed round cake to be attached to the surface of the sealing ring due to the fact that the surface of the turning block loses contact with the inflation pipe, and therefore gas in the plastic hose body is prevented from overflowing. Through cooperation of the structures, the situation that the plastic hose is inflated insufficiently is avoided, and the interior of the plastic hose can be inflated in all directions.

Description

Technical Field

[0001] The utility model relates to the technical field of plastic hose processing, in particular to a plastic hose inflating tool. Background Art

[0002] Plastic hoses are widely used in civil, agricultural and industrial fields, and their molding has basically achieved mechanized production. After the plastic hose is molded, it enters the finished product packaging stage. In the finished product packaging stage, the molded plastic hose needs to be cut to a fixed length, and then the cut plastic hose is inflated and the two ends are sealed. Finally, the inflated fixed-length plastic hose is coiled and packaged. The purpose of inflation is to prevent the hose from being deformed due to extrusion during transportation and storage.

[0003] A Chinese patent discloses a plastic hose inflator with a publication number of CN217515548U, and the application date is 2022.06.03. The patented technology places the plastic hose between two groups of extrusion components, and the driving mechanism drives multiple extrusion rollers to squeeze the plastic hose in turn, so that the gas in the plastic hose moves axially, and multiple extrusion rollers cyclically and repeatedly squeeze the plastic hose in turn, so that the gas continuously moves axially, thereby realizing the inflation of the plastic hose. The device is different from the prior art that can only inflate the plastic hose through the end. It can be used at any position of the plastic hose, and can be inflated before being cut to a fixed length, or it can be inflated after being cut to a fixed length, realizing the automatic uninterrupted continuous production of the plastic hose. However, the above-mentioned device inflates the front end of the plastic tube by squeezing the rear end of the plastic tube. Since the inflation depends on squeezing, the front part of the plastic tube may be insufficiently inflated, and the end of the plastic tube cannot be inflated in this way. Therefore, the inventor provides a plastic hose inflation tool to solve the problems raised in the above-mentioned background technology. Summary of the invention

[0004] The utility model aims to provide a plastic hose inflation tool, which can inflate the plastic hose more fully.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A plastic hose inflation tool, comprising a mounting seat, the top of the mounting seat is fixedly connected to an inflation pump, the output end of the inflation pump is fixedly connected to an inflation tube, a plastic hose body is provided on one side of the mounting seat, a plug is inserted into the right end of the plastic hose body, a closing mechanism is provided on one side of the plastic hose body, the closing mechanism comprises an insert ring inserted into the left end of the plastic hose body, one side of the insert ring is fixedly connected to a connector, the inner side of the connector is fixedly connected to a fixing ring, one side of the fixing ring is provided with a pair of flippable closing blocks; a positioning mechanism is provided on the outer side of the inflation tube.

[0007] As a further solution of the utility model: a pair of connecting frames are fixedly connected to one side of the fixing ring, and the inner sides of the two connecting frames are rotatably connected with flip blocks through movable shafts, one side of the flip block is fixedly connected to the closing block, one side end of the closing block is fixedly connected to a support spring, and one side of the support spring is fixedly connected to the inner wall of the connecting head.

[0008] As a further solution of the utility model: a sealing strip is arranged on one side of the closing block, and the sealing strip is made of rubber material.

[0009] As a further solution of the utility model: the positioning mechanism includes a positioning tube arranged on the outside of the inflation tube, the positioning tube is fixedly connected to the surface of the inflation pump, and positioning grooves are respectively provided on both sides of the interior of the positioning tube, a connecting spring is fixedly connected to one side of the two positioning grooves, a positioning block is fixedly connected to one side of the connecting spring, and the side surface of the positioning block is adapted to the cross-sectional size of the positioning groove; fixing grooves are respectively provided on both sides of the top of the connecting head.

[0010] As a further solution of the utility model: one side of the positioning block is semicircular, and the outer diameter of the connector is matched with the inner diameter of the positioning tube.

[0011] As a further solution of the utility model: guide blocks are fixedly connected to both sides of the interior of the positioning tube, and guide grooves are provided on both sides of the connecting head.

[0012] As a further solution of the utility model: a touch sensor is fixedly connected to the top of the inflation tube, a controller is fixedly connected to the front of the mounting seat, and the controller is electrically connected to the touch sensor and the inflation pump.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The plastic hose inflation tool is configured by inserting a connector into the outside of the inflation tube. When plugged in, the outer wall of the inflation tube pushes the two closing blocks and the corresponding flipping blocks to flip in opposite directions with the position of the movable axis as the center of the circle, thereby exposing the inside of the connector and compressing the support spring. Then, the inflation pump is started through an external power supply, and the output end of the inflation pump fills the inside of the plastic hose body with air through the inflation tube. When the inflation is completed, the connector is pulled outwards. Since the surface of the flipping block loses contact with the inflation tube, the support spring rebounds and drives the closing blocks to flip in opposite directions to form a closed round cake that fits the surface of the closed ring, thereby preventing the gas inside the plastic hose body from overflowing. The coordination of the above structure avoids insufficient inflation of the plastic hose, and the inside of the plastic hose can be inflated in all directions.

[0015] In addition, the plastic hose inflation tooling, when the connector is connected to the inflation tube, the connector will be inserted into the positioning tube first. When the left surface of the connector contacts the surface of the positioning block, the contact force causes the positioning block to move into the positioning groove, and at the same time compresses the connection spring until the fixed groove corresponds to the position of the positioning block. The connection spring loses its restriction and drives the positioning block to move inward and insert into the fixed groove, thereby positioning the connector and preventing the connector from being disjointed, and also eliminating the need for the staff to hold the connector in their hands during inflation. After inflation, pull the connector to the right, the inner wall of the fixed groove squeezes the surface of the positioning block, and the squeezing force also causes the positioning block to move outward, making it easier to remove the connector.

DETAILED DESCRIPTION

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] like Figure 1 , 2 As shown in 4, a plastic hose inflation tool includes a mounting seat 10, the top of the mounting seat 10 is fixedly connected to an inflation pump 11, the output end of the inflation pump 11 is fixedly connected to an inflation tube 12, a plastic hose body 20 is arranged on the right side of the mounting seat 10, and a plug 21 is inserted at the right end of the plastic hose body 20.

[0023] When in use, the left end of the plastic hose body 20 is inserted into the interior of the inflation tube 12 , and then the inflation pump 11 is started by an external power supply, and the output end of the inflation pump 11 inflates air into the interior of the plastic hose body 20 through the inflation tube 12 .

[0024] When the plastic hose body 20 is inflated, if the input end of the plastic hose body 20 is not blocked, the air inside the plastic hose body 20 may overflow, resulting in insufficient inflation of the plastic hose body 20. Therefore, a sealing mechanism is proposed.

[0025] refer to Figure 2 , 3 The closing mechanism includes an insert ring 31 inserted into the left end of the plastic hose body 20, a connector 30 is fixedly connected to the left side of the insert ring 31, a fixing ring 32 is fixedly connected to the left side of the connector 30, and a pair of flippable closing blocks 35 are arranged on the right side of the fixing ring 32.

[0026] Specifically, the upper and lower ends of the right side of the fixed ring 32 are fixedly connected with connecting frames 33 respectively, and the front and rear sides inside the two connecting frames 33 are rotatably connected with flip blocks 34 through movable shafts, and the opposite ends of the two flip blocks 34 are fixedly connected to the closing block 35, and the right side end of the closing block 35 is fixedly connected with a support spring 37, and the right side of the support spring 37 is fixedly connected to the inner wall of the connecting head 30.

[0027] When in use, the connector 30 is inserted into the outside of the inflation tube 12. When plugged in, the outer wall of the inflation tube 12 pushes the two closing blocks 35 and the corresponding flipping blocks 34 to flip back and forth with the position of the movable axis as the center of the circle, exposing the inside of the connector 30 to facilitate inflation of the inflation tube 12 and compress the support spring 37. When inflation is completed, the connector 30 is pulled outward. Since the surface of the flipping block 34 loses contact with the inflation tube 12, the support spring 37 rebounds and drives the closing blocks 35 to flip toward each other to form a closed round cake that fits the surface of the fixing ring 32, thereby preventing the gas inside the plastic hose body 20 from overflowing.

[0028] Preferably, sealing strips 36 are provided on opposite sides of the two closing blocks 35 . The sealing strips 36 are made of rubber. When the two closing blocks 35 are attached, the two sealing strips 36 are attached together to reduce the connection gap between the two closing blocks 35 , further preventing the internal gas of the plastic hose body 20 from escaping.

[0029] During the inflation process, the worker needs to keep pressing the connector 30 against the outside of the inflation tube 12 , which is very labor-intensive. Therefore, a positioning mechanism is proposed.

[0030] refer to Figure 4The positioning mechanism includes a positioning tube 40 arranged on the outside of the inflation tube 12, the positioning tube 40 is fixedly connected to the surface of the inflation pump 11, and positioning grooves 41 are respectively provided on the upper and lower sides of the interior of the positioning tube 40, and connecting springs 42 are fixedly connected to the opposite sides of the two positioning grooves 41, and positioning blocks 43 are fixedly connected to the opposite sides of the two springs 42 to be connected, and the side surfaces of the positioning blocks 43 are adapted to the cross-sectional size of the positioning grooves 41, so as to achieve the effect of guiding the positioning blocks 43 when moving; fixed grooves 38 are respectively provided on the upper and lower sides of the top of the connecting head 30.

[0031] Preferably, the opposite sides of the two positioning blocks 43 are semicircular, and the outer diameter of the connector 30 is adapted to the inner diameter of the positioning tube 40. When the connector 30 is connected to the inflation tube 12, the connector 30 will be inserted into the positioning tube 40 first. When the left surface of the connector 30 contacts the surface of the positioning block 43, the contact force causes the positioning block 43 to move into the interior of the positioning groove 41, and at the same time compresses the connecting spring 42, until the fixed groove 38 corresponds to the position of the positioning block 43, the connecting spring 42 loses its restriction and drives the positioning block 43 to move inward and insert into the interior of the fixed groove 38, thereby achieving the positioning of the connector 30 and preventing the connector 30 from being disjointed, and also eliminating the need for the staff to hold the connector 30 during inflation. After inflation, pull the connector 30 to the right, the inner wall of the fixed groove 38 squeezes the surface of the positioning block 43, and the squeezing force also causes the positioning block 43 to move outward, thereby facilitating the removal of the connector 30.

[0032] Preferably, reference Figure 1 , 4 The front and rear sides of the positioning tube 40 are fixedly connected with guide blocks 44, and the front and rear sides of the connector 30 are provided with guide grooves 39. Before the connector 30 is inserted into the positioning tube 40, the position of the guide block 44 is made to correspond to the position of the guide groove 39, and then when the connector 30 is inserted, the guide block 44 is driven to slide along the inside of the guide groove 39, so as to guide the connector 30 when it moves, and prevent the fixed groove 38 from not corresponding to the position of the positioning block 43.

[0033] Preferably, reference Figure 1 , 4 , a touch sensor 45 is fixedly connected to the top of the inflation tube 12, and a controller 46 is fixedly connected to the front of the mounting base 10, and the controller 46 is electrically connected to the touch sensor 45 and the inflation pump 11. When the connector 30 is fully inserted into the outside of the inflation tube 12, the left side of the connector 30 contacts the sensing end of the touch sensor 45, so that the touch sensor 45 feeds back a signal to the controller 46, and the controller 46 starts the inflation pump 11, and then the inflation pump 11 inflates the inside of the plastic hose body 20 through the inflation tube 12; after the inflation is completed, the connector 30 is pulled out and separated from the touch sensor 45, so that the inflation pump 11 is turned off by the controller 46, thereby eliminating the process of frequently turning the inflation pump 11 on and off.

[0034] The working principle of the utility model is: insert the connector 30 into the outside of the inflation tube 12, and when plugged in, the outer wall of the inflation tube 12 pushes the two closing blocks 35 and the corresponding flipping blocks 34 to flip back and forth with the position of the movable axis as the center of the circle, so that the inside of the connector 30 is exposed, and the support spring 37 is compressed at the same time, and then the inflation pump 11 is started by an external power supply, and the output end of the inflation pump 11 fills the inside of the plastic hose body 20 with air through the inflation tube 12. When the inflation is completed, the connector 30 is pulled outward, and because the surface of the flipping block 34 loses contact with the inflation tube 12, the support spring 37 rebounds and drives the closing block 35 to flip toward each other to form a closed round cake that fits the surface of the fixing ring 32, thereby preventing the gas inside the plastic hose body 20 from overflowing.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
