Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to a detachable hose joint for a concrete pump hose. Background Technique

[0002] The concrete pump hose is an important accessory for concrete transportation in construction projects, usually referring to the hose of a concrete pump, named because concrete is abbreviated as "砼".

[0003] At present, a hose joint is required for connecting the concrete pump hose. However, the common hose joints are rather cumbersome and time-consuming when fixing the connected concrete pump hose, and the connection firmness and tightness may be insufficient. For example, the detachable hose joint for a concrete pump hose disclosed in the publication number CN213809368U includes a concrete pump hose and a hose joint; a first rotating shaft is provided on one side of the concrete pump hose, a limiting block is fixedly connected to the periphery of the first rotating shaft, a pushing block and a fixing block are provided on one side of the hose joint, a clamping block is rotatably fitted to the periphery of the third rotating shaft, a fourth rotating shaft is slidably fitted to one side of the clamping block, and a rod body is fixedly connected to one side of the fourth rotating shaft.

[0004] As can be seen from the above disclosed solution, when the hose joint is connected to the concrete pump hose, positioning is carried out by means of clamping, which may result in insufficient extrusion strength of the concrete pump hose, thereby reducing the connection firmness and tightness between the concrete pump hose and the hose joint, and it is also rather inconvenient during installation and disassembly. Content of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a detachable hose joint for a concrete pump hose. This detachable hose joint for a concrete pump hose, through the provided elastic support rod, positioning ring and anti-detachment groove, can not only bundle and fix the connected concrete pump hose, but also improve the connection firmness and tightness of the concrete pump hose through the extrusion of the positioning ring and anti-detachment groove, and through the provided rotating sleeve, elastic teeth, clamping teeth and handle rod, it is convenient for users to easily install and disassemble the extrusion sleeve, and thus easily tighten the positioning ring, improving the usability.

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] A detachable hose connector for concrete pump hoses includes a concrete pump hose body and a hose connector body, which are detachably connected. The hose connector body includes a connecting sleeve, and an axially symmetrical support tube is fixedly connected to the inner wall of the connecting sleeve. One end of the support tube has a tapered end with a connecting hole. Both ends of the connecting sleeve are fixedly connected to axially symmetrical positioning mechanisms. A screw is detachably connected to the surface of the positioning mechanism, and a fixing sleeve is fixedly connected to one end of the screw. A disassembly sleeve engages with the surface of the fixing sleeve, and a locking component is threaded onto the surface of the screw. This detachable hose connector for concrete pump hoses, through the design of the elastic support rod, positioning ring, and anti-disengagement groove, can not only bind and fix the connected concrete pump hose, but also improve the connection firmness and sealing of the concrete pump hose through the compression of the positioning ring and anti-disengagement groove. Furthermore, the design of the rotating sleeve, elastic teeth, locking teeth, and handle makes it easy for users to install and remove the compression sleeve, thereby easily tightening the positioning ring, improving ease of use.

[0008] Furthermore, the positioning mechanism includes a positioning ring, on the surface of which a support rod is fixedly connected. One end of the support rod is provided with a bent portion. The support rod is made of an elastic metal plate. An extrusion plate, a first connecting ear, and a second connecting ear are fixedly connected to the opening of the positioning ring. The support rod can support the position of the positioning ring and can automatically deform when the positioning ring is tightened, without affecting the inward retraction of the positioning ring.

[0009] Furthermore, the locking assembly includes a compression sleeve, one end of which has a threaded hole. The inner wall of the threaded hole is threadedly connected to the surface of the screw rod. A rotating sleeve is engaged with the surface of the compression sleeve, allowing the compression sleeve to move on the surface of the screw rod, which facilitates the tightening of the positioning ring.

[0010] Furthermore, a handle is fixedly connected to the surface of the rotating sleeve, and a rotating hole is opened at one end of the rotating sleeve. An elastic tooth is fixedly connected to the inner wall of the rotating hole, and a buffer groove is provided on the surface of the elastic tooth. The rotating sleeve is easy for the user to manually rotate by the handle and can be freely rotated counterclockwise on the surface of the compression sleeve.

[0011] Furthermore, the surface of the extrusion sleeve has a rotating groove, and the inner wall of the rotating groove is fixedly connected with annularly distributed locking teeth. Adjacent locking teeth form a locking groove, which meshes with the elastic teeth, so that the rotation of the rotating sleeve can drive the extrusion sleeve to tighten clockwise.

[0012] Furthermore, the surface of the support tube is provided with an anti-detachment groove, which is circular in shape. After the anti-detachment groove is pressed against the inner wall of the concrete pump hose body, it can increase the sealing and anti-slip performance.

[0013] Furthermore, an insertion groove is formed between the outer side of the support pipe and the inner wall of the connecting sleeve, which facilitates quick pre-positioning of one end of the concrete pump hose body.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution can not only bind and fix the connected concrete pump hose by setting elastic support rods, positioning rings and anti-detachment grooves, but also improve the connection firmness and sealing of the concrete pump hose by squeezing the positioning rings and anti-detachment grooves.

[0016] (2) This solution, through the setting of rotating sleeve, elastic teeth, locking teeth and handle, makes it easy for users to install and remove the squeezing sleeve, and thus easily tighten the positioning ring, improving the ease of use. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] Please see Figure 1-5 A detachable hose connector for concrete pump hoses includes a concrete pump hose body 4 and a hose connector body 1, which are detachably connected. The hose connector body 1 includes a connecting sleeve 11, and an axially symmetrical support tube 12 is fixedly connected to the inner wall of the connecting sleeve 11. One end of the support tube 12 is provided with a tapered end 13, and one end of the tapered end 13 has a connecting hole 14. The two ends of the connecting sleeve 11 are fixedly connected with axially symmetrical positioning mechanisms 2, which include a positioning ring 22. A support rod 21 is fixedly connected to the surface of the positioning ring 22. One end of the support rod 21 is provided with a bent part. The support rod 21 is made of elastic metal plate. A pressing plate 26, a first connecting ear 23, and a second connecting ear 24 are fixedly connected to the opening of the positioning ring 22. After the positioning ring 22 is tightened, the pressing plates 26 contact each other and simultaneously press the surface of the concrete pump hose body 4. The first connecting ear 23 and the second connecting ear 24 have bolt holes. The support rod 21 can adjust the position of the positioning ring 22. The positioning mechanism 2 has a support structure that automatically deforms when the positioning ring 22 is tightened, without affecting the inward retraction of the positioning ring 22. A screw 27 is detachably connected to the surface of the positioning mechanism 2, and a fixing sleeve 25 is fixedly connected to one end of the screw 27. The surface of the fixing sleeve 25 is provided with the same locking teeth 33 as the compression sleeve 31. The disassembly sleeve 28 can freely rotate clockwise on the surface of the fixing sleeve 25. The inner wall of the disassembly sleeve 28 is provided with the same elastic teeth 37 as the rotating sleeve 35. The disassembly sleeve 28 can drive the fixing sleeve 25 to rotate counterclockwise, thereby driving the screw 27 to rotate counterclockwise, which facilitates the loosening of the positioning ring 22. The disassembly sleeve 28 is engaged with the surface of the fixing sleeve 25. A locking assembly 3 is threadedly connected to the surface of the screw 27. The locking assembly 3 includes a compression sleeve 31. One end of the compression sleeve 31 has a screw hole, and the inner wall of the screw hole is threadedly connected to the surface of the screw 27. A rotating sleeve 35 is engaged with the surface of the compression sleeve 31. The compression sleeve 31 can move on the surface of the screw 27, which facilitates the tightening of the positioning ring 22.

[0026] A handle 39 is fixedly connected to the surface of the rotating sleeve 35. A rotating hole 36 is opened at one end of the rotating sleeve 35. An elastic tooth 37 is fixedly connected to the inner wall of the rotating hole 36. A buffer groove 38 is provided on the surface of the elastic tooth 37. The rotating sleeve 35 is easy for the user to rotate manually by the handle 39. It can rotate freely counterclockwise on the surface of the extrusion sleeve 31. A rotating groove 32 is opened on the surface of the extrusion sleeve 31. A ring of equally spaced locking teeth 33 is fixedly connected to the inner wall of the rotating groove 32. A locking groove 34 is formed between adjacent locking teeth 33. The locking groove 34 engages with the elastic tooth 37, so that the rotation of the rotating sleeve 35 can drive the extrusion sleeve 31 to tighten clockwise.

[0027] The surface of the support pipe 12 has an anti-detachment groove 16. The anti-detachment groove 16 is circular in shape. After the anti-detachment groove 16 is squeezed against the inner wall of the concrete pump hose body 4, it can increase the sealing and anti-slip performance. The outer side of the support pipe 12 and the inner wall of the connecting sleeve 11 are surrounded by an insertion groove 15, which facilitates the quick pre-positioning of one end of the concrete pump hose body 4.

[0028] When using this detachable concrete pump hose connector, first, place one end of the concrete pump hose body 4 onto the surface of the support pipe 12 so that one end abuts against the inner wall of the insertion groove 15. Then, fix the fixing sleeve 25, and then fix the screw 27 to prevent it from rotating. Next, grasp the handle 39 and rotate the rotating sleeve 35, which in turn drives the compression sleeve 31 to rotate clockwise to tighten it to the right. This causes the positioning ring 22 to lock and secure the concrete pump hose body 4, so that the inner wall of the concrete pump hose body 4 contacts and is pressed against the inner wall of the anti-detachment groove 16, thus completing the connection between the concrete pump hose body 4 and the hose connector. Connect the hose connector body 1, and then connect and fix the other end of the hose connector body 1 to the concrete pump hose body 4 to be connected in the above manner. When it is necessary to disassemble the concrete pump hose body 4, the compression sleeve 31 can be fixed, and then the disassembly sleeve 28 can be manually rotated to drive the fixing sleeve 25 to rotate counterclockwise. The counterclockwise rotation of the fixing sleeve 25 drives the screw 27 to rotate counterclockwise, thereby causing the compression sleeve 31 to move to the left to loosen the compression on the positioning ring 22, thereby causing the positioning ring 22 to loosen the binding on the concrete pump hose body 4, and then the concrete pump hose body 4 can be removed.

[0029] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
