Description

Technical Field

[0001] This utility model belongs to the field of hose reel technology, specifically relating to a hose pressing device for hose reels. Background Technology

[0002] In the cleaning and rinsing industry, the hoses used are generally quite long, and most of them are made of rubber or plastic. They range from a dozen meters to tens or even hundreds of meters in length. After the rinsing operation is completed, the long hoses pose a problem for storage.

[0003] To address the shortcomings of existing hose reels, which often produce messy, disorganized, and loosely wound hoses by cranking the handle, Chinese patent document CN208086949U discloses a diagonal spring-type hose pressing device for hose reels. This device includes a hose clamping member that works with the hose reel and is positioned outside it. Two clamping adjustment supports are located on either side of the clamping member. Each clamping adjustment support has a rotating shaft in its middle section. The inner end of each shaft is movably inserted into the corresponding clamping adjustment support, and the outer end is movably connected to a fixed support via a fastening nut. The support plates at the ends of each fixed support are symmetrically fixed to the external hose reel's bracket. This device features a reasonable structural design, simple operation, and when installed on the outside of the hose reel, it effectively compresses the hose on the reel, ensuring a tight and secure winding.

[0004] However, the above technical solutions have the following technical problems: 1. When the tube is wound, the diameter will gradually increase as the winding diameter increases. When the tube winding diameter changes greatly, the corresponding spring angle will open too much. Frequent use will shorten the spring life. At the same time, when the spring is stretched too much, it will also cause excessive compression of the tube; 2. The hose clamping part is directly connected to the shaft and installed on one side of the hose reel, which is not easy to install, remove and replace for maintenance. Utility Model Content

[0005] This utility model provides a pipe pressing device for a pipe reel. Through an elastic clamping mechanism, the pressure roller shaft continuously presses the pipe. When the pipe diameter increases, the support frame compresses the buffer spring and descends. After the support frame descends, the opening angle can be reduced, the spring life can be extended, and excessive compression is less likely to occur. This pipe pressing mechanism can be easily replaced and maintained by pulling the support frame outward by hand to open it, allowing the positioning pin to disengage from the positioning groove. This solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hose reel pressing device, comprising a hose reel body, a reel, and a spool disposed on the outside for blocking the hose on the reel; The power mechanism drives the drum to rotate by manually rotating a handle; It also includes a support frame, with both ends of the reel mounted on parallel support arms via bearings through a rotating shaft, and a base set at the bottom of the support frame; It also includes a tube pressing mechanism, which includes two pressure roller shafts on both sides. The pressure roller shafts are rotatably mounted on an elastic clamping mechanism, and the outer wall of the pressure roller shaft is covered with a silicone sleeve. The elastic clamping mechanism elastically tightens the pressure roller shafts on both sides, so that the pressure roller shafts on both sides press against the outside of the tube on the inner drum of the reel, thereby continuously tightening the pressure roller shafts on both sides during tube winding.

[0007] Preferably, the elastic clamping mechanism includes a support base, with support frames hinged to the mounting edges respectively, a connecting rod welded to the middle of the support frame, a pressure roller shaft rotatably mounted at the end of the support frame, and a tension spring installed between the connecting rods on both sides.

[0008] Preferably, the elastic clamping mechanism further includes a positioning column, and a positioning groove corresponding to the positioning column is provided on the base. When the support frame of the elastic clamping mechanism is working elastically, the base can be raised and lowered, and guided and positioned by the positioning groove.

[0009] Preferably, two positioning posts are provided, and two corresponding positioning slots are also provided, so that the cooperation between the two positioning posts and the positioning slots prevents the elastic clamping mechanism from rotating around the positioning slots.

[0010] Preferably, the positioning column is also fitted with a buffer spring. By setting the buffer spring, when the diameter of the pipe increases, the support frame can squeeze the buffer spring to descend, and the opening angle can be reduced after the support frame descends.

[0011] Preferably, the connecting rod is welded to the support frame near the bottom.

[0012] Preferably, two tension springs are provided on the connecting rod, and a limiting mechanism corresponding to the tension spring hooks is also provided on the connecting rod.

[0013] Preferably, the limiting mechanism consists of two limiting protrusions, with an annular groove formed between the two limiting protrusions, and the hook of the tension spring is hung in the annular groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. During the winding of the tube, the elastic clamping mechanism continuously tightens the pressure rollers on both sides, so that the pressure rollers continuously compress the tube. The wound tube will not be loose, will not overlap, and will not wrap across tubes. Instead, it will be wound regularly, one circle at a time, layer by layer, onto the drum of the tube winder.

[0015] 2. When the pipe diameter increases, the support frame compresses the buffer spring and descends. After the support frame descends, the opening angle can be reduced, the spring life can be extended, and excessive compression is less likely to occur.

[0016] 3. The clamping mechanism can be easily replaced or repaired by pulling the support frame outward by hand to open it, allowing the positioning column to disengage from the positioning groove. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1-5 This utility model provides a hose reel for a hose reel, including a hose reel body, which is a conventional structure, including a reel 1 and a reel 2 located on the outside for blocking the hose on the reel 1. The tube is wound around the outside of the drum 1, and when needed, the tube is released by rotating the drum 1; The power mechanism in this embodiment is driven by the manual handle 3. The drum 1 is rotated by rotating the manual handle 3. The forward and reverse rotations complete the unloading and reloading of the tube. This is a well-known technology and will not be described in detail here. It also includes a bracket 4. The two ends of the reel 2 are rotatably mounted on the parallel bracket arm via a shaft and bearing. The bracket arm provides stable and strong support. A base 401 is provided at the bottom of the bracket 4. The base 401 is used to provide stable support for the whole. It also includes a tube pressing mechanism, which includes two pressure roller shafts 5 on both sides. The pressure roller shafts 5 are rotatably mounted on the elastic clamping mechanism. The outer wall of the pressure roller shaft 5 is covered with a silicone sleeve, which is durable and reduces wear on the pressed tube. The length of the pressure roller shaft 5 covers the width of the tube winding. The elastic clamping mechanism elastically tightens the pressure roller shafts 5 on both sides, so that the pressure roller shafts 5 on both sides press against the outside of the tube on the inner drum 1 of the reel 2. Thus, when the tube is wound, the continuous tightening of the pressure roller shafts 5 on both sides by the elastic clamping mechanism makes the pressure roller shafts 5 continuously compact the tube. The wound tube will not be loose, will not overlap, and will not wrap across tubes. Instead, it will be wound regularly, one circle at a time, layer by layer, on the drum 1 of the tube winder.

[0021] As a further embodiment, the elastic clamping mechanism includes a support base 6, which is a stainless steel metal base, including a base plate and mounting edges extending upward from the front and rear ends of the base plate. Support frames 7 are respectively hinged to the mounting edges. A connecting rod 8 is welded to the middle of the support frame 7. The connecting rod 8 is made of high-strength hard alloy, which is stable and not easily deformed. The pressure roller shaft 5 is rotatably installed at the end of the support frame 7. A tension spring 9 is installed between the connecting rods 8 on both sides. The tension spring 9 is made of spring steel, which improves the elastic limit, yield strength, fatigue resistance and sufficient toughness, and can recover its original shape without permanent deformation or breakage after being subjected to repeated alternating loads.

[0022] As a further embodiment, the elastic clamping mechanism also includes a positioning post 10, which is made of smooth stainless steel and coated with lubricating oil. The base 401 is provided with a positioning groove 4011 corresponding to the positioning post 10. When the support frame 7 of the elastic clamping mechanism is working elastically, the base 401 can be raised and lowered, and guided and positioned by the positioning groove 4011.

[0023] As a further embodiment, two positioning posts 10 are provided, and two corresponding positioning grooves 4011 are also provided. The cooperation between the two positioning posts 10 and the positioning grooves 4011 prevents the elastic clamping mechanism from rotating around the positioning grooves 4011 and enhances the stability during the tube pressing process.

[0024] As a further embodiment, a buffer spring 11 is also fitted on the positioning post 10. The buffer spring 11 is made of high-strength alloy spring steel. When the tube is wound, the diameter will change as the winding gradually increases. When the diameter of the tube changes significantly, the angle of the corresponding support frame 7 will open too much, which will not only affect the life of the spring, but also easily cause excessive compression of the tube. By setting the buffer spring 11, when the diameter of the tube increases, the support frame 7 can squeeze the buffer spring 11 to drop. After the support frame 7 drops, the opening angle can be reduced, the life of the spring can be extended, and excessive compression is less likely to occur.

[0025] As a further embodiment, the connecting rod 8 is welded to the support frame 7 near the bottom, which can reduce the length of the tension spring 9 on the one hand, and prevent the tension spring 9 from interfering with the pipe above on the other hand.

[0026] As a further embodiment, two tension springs 9 are provided on the connecting rod 8, which makes it easier to maintain balance. At the same time, a limiting mechanism corresponding to the hook of the tension spring 9 is provided on the connecting rod 8.

[0027] As a further embodiment, the limiting mechanism consists of two limiting protrusions 12, with an annular groove formed between the two limiting protrusions 12. The hook of the tension spring 9 is hung in the annular groove, thereby achieving stable limiting.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0029] Working principle: The manual handle 3 rotates to drive the drum 1 to rotate, completing the tube winding action. During tube winding, the elastic clamping mechanism continuously tightens the pressure rollers 5 on both sides, making the pressure rollers 5 continuously compress the tube. The wound tube will not be loose, overlap, or cross-tube, but will be wound regularly, one circle at a time, layer by layer, on the drum 1 of the tube winder. By setting a buffer spring 11, when the tube diameter increases, the support frame 7 squeezes the buffer spring 11 to descend. After the support frame 7 descends, the opening angle can be reduced, the spring life can be extended, and excessive compression is less likely to occur. In addition, the tube pressing mechanism can be opened by pulling the support frame 7 outward by hand, so that the positioning post 10 can be disengaged from the positioning groove 4011 for replacement and maintenance, which is very convenient.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
