Description

Technical Field

[0001] The utility model relates to the technical field of corrugated hose connectors, in particular to a hose connector which is easy to install. Background Art

[0002] Corrugated hose is a kind of pipe fitting with flexible and pressure-resistant properties. Corrugated hoses made of non-metallic materials such as PE (polyethylene), PP (polypropylene) and PA (nylon) also have certain flexibility and anti-twisting ability.

[0003] Existing corrugated hose connectors are usually fixed with connecting clamps when assembled with hoses. However, when there is a certain gap between the two sections of corrugated connecting hoses when connected, the hose connector cannot seal the two sections of corrugated connecting hoses together. In addition, the fasteners between the two sections of corrugated connecting hoses and the connector are tightened by screwing the threads, which makes disassembly and assembly extremely inconvenient. Utility Model Content

[0004] The purpose of the utility model is to provide a hose connector that is easy to install. The hose connector that is easy to install can achieve close connection of two sections of corrugated hoses with a certain gap, and the fasteners between the hoses and the connector can be quickly disassembled and assembled.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a hose connector that is easy to install, comprising a first corrugated hose and a second corrugated hose, a connecting mechanism being provided between the first corrugated hose and the second corrugated hose, the connecting mechanism comprising a connecting pipe, connecting blocks being symmetrically fixedly installed on the outer circumference of the connecting pipe, spline sleeves and spline shafts being fixedly installed on adjacent surfaces of two groups of connecting blocks on the same side, fasteners being provided at both ends of the connecting mechanism, the fasteners comprising a fastening belt and a fixing belt, the fastening belt and the fixing belt being integrally formed into an annular structure, a positioning seat being fixedly installed on the fixing belt near one end of the fastening belt, bite grooves being provided at equal intervals on the outside of the fastening belt and the fixing belt, a second bolt being installed on the top of the positioning seat, and a wedge block being rotatably installed on the bottom end of the second bolt.

[0006] Preferably, the connecting pipe has the same material structure as the first corrugated hose and the second corrugated hose.

[0007] Preferably, one end of the spline shaft is inserted into the inner wall of the spline sleeve, and a first bolt is threadedly mounted on the outside of the spline sleeve.

[0008] Preferably, the end of the fastening belt close to the fixing belt is inserted into an opening on one side of the positioning seat, and a positioning hole is provided on the top of the positioning seat.

[0009] Preferably, a thread is provided on the outside of the second bolt near the top, and the second bolt and the bottom wedge block are respectively located in the inner cavity of the positioning seat.

[0010] Preferably, a compression spring is fixedly installed between the positioning seat and the outside of the second bolt, and a guide groove matching the wedge block is fixedly installed on the top of the inner cavity of the positioning seat. The wedge block slides in the guide groove and conflicts with the corresponding engagement groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] When a gap exists at the connection between the first corrugated hose and the second corrugated hose in the utility model, the first corrugated hose and the second corrugated hose can be tightly connected by corrugating and stretching the connecting pipe in the connecting mechanism, and the middle part of the connecting pipe can be supported and positioned by the spline shaft and the spline sleeve on both sides, and can be positioned by the first bolt, so that after the connecting mechanism connects the two sections of hose, it can ensure that the connecting section forms a straight line and is unobstructed. In this way, even if a gap exists between the first corrugated hose and the second corrugated hose, they can still be tightly connected together through the connecting mechanism;

[0013] The utility model pulls the fastening belt in the fastener so that the fastening belt and the fixing belt form an annular contraction, so that the external bite groove can resist the second bolt to the outside when passing the bottom of the positioning seat, and the second bolt can form a certain pressing force with the bite groove under the positioning of the compression spring. In this way, after the fastening belt is pulled and paused, the wedge block can quickly bite and position the bite groove in the guide groove, and subsequently, the second bolt can be screwed to allow the wedge block in the guide groove to extend into the bite groove for stable positioning.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-5 The utility model provides a technical solution: a hose connector that is easy to install, including a first corrugated hose 1 and a second corrugated hose 2. A connecting mechanism 3 is provided between the first corrugated hose 1 and the second corrugated hose 2. The connecting mechanism 3 includes a connecting tube 31. Connecting blocks 32 are symmetrically fixedly installed on the outer circumference of the connecting tube 31. Adjacent surfaces of two groups of connecting blocks 32 on the same side are respectively fixedly installed with spline sleeves 33 and spline shafts 34.

[0022] A fastener 4 is provided at each end of the connection mechanism 3. The fastener 4 includes a fastening belt 41 and a fixing belt 42. The fastening belt 41 and the fixing belt 42 are integrally formed into a ring structure. A positioning seat 43 is fixedly installed on the fixing belt 42 near one end of the fastening belt 41. Engaging grooves 44 are equidistantly provided on the outside of the fastening belt 41 and the fixing belt 42. A second bolt 46 is installed on the top of the positioning seat 43. A wedge block 48 is rotatably installed on the bottom end of the second bolt 46.

[0023] When there is a gap at the connection between the first corrugated hose 1 and the second corrugated hose 2, the first corrugated hose 1 and the second corrugated hose 2 can be tightly connected by corrugating the connecting tube 31 in the connecting mechanism 3, and the middle part of the connecting tube 31 can be supported and positioned by the spline shaft 34 and the spline sleeve 33 on both sides, and can be positioned by the first bolt 35, so that after the connecting mechanism 3 connects the two sections of the hose, it can ensure that the connecting section forms a straight line and is unobstructed. In this way, even if there is a gap between the first corrugated hose 1 and the second corrugated hose 2, they can still be tightly connected together through the connecting mechanism 3;

[0024] By pulling the fastening belt 41 in the fastener 4, the fastening belt 41 and the fixing belt 42 form an annular contraction, so that the external engaging groove 44 can resist the second bolt 46 to the outside when passing through the bottom of the positioning seat 43, and the second bolt 46 can form a certain pressing force with the engaging groove 44 under the positioning of the compression spring 47. In this way, after the fastening belt 41 is pulled and paused, the wedge block 48 can quickly engage and position the engaging groove 44 in the guide groove. Subsequently, by screwing the second bolt 46, the wedge block 48 in the guide groove can be extended into the engaging groove 44 for firm positioning.

[0025] The connecting tube 31 has the same material structure as the first corrugated hose 1 and the second corrugated hose 2. When there is a gap at the connection between the first corrugated hose 1 and the second corrugated hose 2, corrugated stretching can be performed through the connecting tube 31 in the connecting mechanism 3.

[0026] Among them, one end of the spline shaft 34 is inserted into the inner wall of the spline sleeve 33, and the first bolt 35 is installed on the outside of the spline sleeve 33 through a thread. The middle part of the connecting tube 31 can be supported and positioned by the spline shaft 34 and the spline sleeve 33 on both sides, and can be positioned by the first bolt 35, so that after the connecting mechanism 3 connects the two sections of the hose, it can ensure that the connecting section forms a straight line and is unobstructed.

[0027] Among them, the end of the fastening belt 41 close to the fixing belt 42 is inserted into the opening on one side of the positioning seat 43. A positioning hole 45 is provided on the top of the positioning seat 43. By tightening the second bolt 46, the wedge block 48 in the guide groove can extend into the bite groove 44 for firm positioning.

[0028] Among them, the outside of the second bolt 46 is provided with a thread near the top, and the second bolt 46 and the bottom wedge block 48 are respectively located in the inner cavity of the positioning seat 43, and a compression spring 47 is fixedly installed between the positioning seat 43 and the outside of the second bolt 46. A guide groove matching the wedge block 48 is fixedly installed on the top of the inner cavity of the positioning seat 43, and the wedge block 48 slides in the guide groove and interferes with the corresponding bite groove 44. By pulling the fastening belt 41 in the fastener 4, the fastening belt 41 and the fixing belt 42 form an annular contraction, so that the external bite groove 44 can interfere with the second bolt 46 to the outside when passing through the bottom of the positioning seat 43, and the second bolt 46 can form a certain pressing force with the bite groove 44 under the positioning of the compression spring 47. In this way, after the fastening belt 41 is paused, the wedge block 48 can quickly engage and position the bite groove 44 in the guide groove.

[0029] Working principle: When in use, if there is a gap at the connection between the first corrugated hose 1 and the second corrugated hose 2, the connecting tube 31 in the connecting mechanism 3 can be used for corrugation stretching to tightly connect the first corrugated hose 1 and the second corrugated hose 2. The middle part of the connecting tube 31 can be supported and positioned by the spline shaft 34 and the spline sleeve 33 on both sides, and can be positioned by the first bolt 35. After the connecting mechanism 3 connects the two sections of the hose, it can ensure that the connection section forms a straight line and is unobstructed. In this way, even if there is a gap between the first corrugated hose 1 and the second corrugated hose 2, they can still be tightly connected together through the connecting mechanism 3.

[0030] Then, the fasteners 4 at both ends of the connecting tube 31 are moved to the corrugated groove at the connection of the corrugated hose respectively, and the fastening belt 41 in the fastener 4 is pulled out, so that the fastening belt 41 and the fixing belt 42 form an annular contraction, so that the external bite groove 44 can resist the second bolt 46 to the outside when passing through the bottom of the positioning seat 43, and the second bolt 46 can form a certain pressing force with the bite groove 44 under the positioning of the compression spring 47. In this way, after the fastening belt 41 is pulled out and paused, the wedge block 48 can quickly bite and position the bite groove 44 in the guide groove, and then the second bolt 46 can be screwed to allow the wedge block 48 in the guide groove to extend into the bite groove 44 for firm positioning.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to these embodiments without departing from the principles of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
