Description

Technical Field

[0001] This utility model relates to the field of hose reel technology, specifically to an explosion-proof hose reel reel device. Background Technology

[0002] Currently, fire hoses, industrial hoses, and other similar equipment need to be wound and stored using a rewinding machine after use for easy transportation and future use. Most rewinding machines typically use a rewinding bar with a clamping structure to clamp and secure the beginning of the winding process, preventing the hose from coming loose during winding.

[0003] However, because the retractor needs to clamp the beginning of the hose to secure it, and after retracting, the hose's own weight continues to press on the clamping area, causing that area to be under constant stress. Especially with high-pressure hoses or thicker hoses, prolonged clamping and compression can easily cause deformation, wear, or even breakage of the hose clamping area, affecting the hose's service life.

[0004] Furthermore, most retractors only have a retractor bar to fix the beginning of the hose, while the end (the other end of the hose) after winding lacks a fixing structure. This makes the hose prone to loosening and falling off due to vibration or external force during transportation or storage, affecting the storage effect and potentially causing damage to the hose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0006] An explosion-proof hose reel includes a chassis and a fixed plate fixedly mounted on the chassis. A main shaft is coaxially rotatably mounted on the fixed plate. An operating rod and a fixing rod are eccentrically fixed on both sides of the main shaft. A clamping rod structure is provided on one side of the fixing rod, and the clamping rod structure is mounted on the main shaft.

[0007] The clamping rod structure includes a first sleeve rod, a second sleeve rod, and a third sleeve rod coaxially sleeved from the inside out. The first sleeve rod is fixedly mounted on the main shaft and has a first sliding groove along its axial direction. A first ball bearing is slidably disposed within the first sliding groove and is fixedly mounted on a first end piece. The first end piece is fixedly mounted at the end of the second sleeve rod. The second sleeve rod has a second sliding groove along its axial direction and has a second ball bearing slidably disposed within it. The second ball bearing is fixedly mounted on a second end piece, which is also fixedly mounted at the end of the third sleeve rod. The other end of the third sleeve rod is movably connected to the fixed plate via a connecting structure.

[0008] As a preferred embodiment of this utility model, the connection structure includes an end post, a slot, and an insert post. The end post is fixedly disposed at the end of the third sleeve rod, and a limiting hole is formed on the end post. The slot is disposed through the fixed plate, and an insert post is disposed on the other side of the slot. The insert post is inserted into the limiting hole through the slot to fix the position of the third sleeve rod after rotation.

[0009] As a preferred embodiment of this utility model, the slot is a straight through hole, the length direction of the straight through hole is perpendicular to the first sleeve rod, and the insert can slide in the straight through hole to press the end of the water hose tightly.

[0010] In a preferred embodiment of this utility model, the insert is fixedly mounted on the slide rod, and the slide rod is slidably mounted on the operating rod along the axial direction of the operating rod.

[0011] As a preferred embodiment of this utility model, the operating rod is provided with a horizontal groove through hole, the slide rod is slidably disposed in the horizontal groove through hole along its own axis, and a limit piece is provided at the end of the slide rod.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] This invention first uses a third set of rods and a fixing rod to clamp a section of the hose and then winds it up. After winding, sliding out the third set of rods releases the clamp on the hose end, preventing localized stress on the hose and accelerating its aging and damage process. Furthermore, the wound hose maintains its curled shape due to its internal stress, ensuring smooth winding. Further, by folding the second and third sets of rods respectively, the third set of rods abuts against the outermost edge of the hose, pressing the hose tail end tightly. The connecting structure maintains this pressure, resulting in a more complete curl and reducing the probability of the hose loosening after winding. Attached Figure Description

[0022] 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.

[0023] like Figures 1 to 5 As shown, this utility model provides an explosion-proof hose reel device, including a base 1 placed on the ground and a fixed plate 2 fixedly mounted on the base 1. A main shaft 3 is coaxially rotatable on the fixed plate 2 via bearings or a nested structure. An operating rod 4 and a fixed rod 5 are eccentrically fixed on both sides of the main shaft 3. The operating rod 4 is held by the user to rotate the main shaft 3, thereby driving the hose reel in. A clamping structure is provided on one side of the fixed rod 5, and the clamping structure is mounted on the main shaft 3. A certain gap exists between the clamping structure and the fixed rod 5 for inserting one end of the hose. Once one end of the hose is inserted into the gap, rotating the main shaft 3 will reel the hose in to the outside of the fixed plate.

[0024] like Figure 3 As shown, the clamping rod structure includes a first sleeve rod 6, a second sleeve rod 7, and a third sleeve rod 8 that are coaxially sleeved from the inside to the outside. One end of the first sleeve rod 6 is fixedly mounted on the main shaft 3. A first sliding groove 9 is provided on the first sleeve rod 6. The first sliding groove 9 is opened along the axial direction of the first sleeve rod 6. A first ball bearing 10 is slidably disposed in the first sliding groove 9. The first ball bearing 10 is fixedly mounted on a first end piece 11. The first end piece 11 is fixedly mounted on the end of the second sleeve rod 7.

[0025] The second sleeve rod 7 is slidably disposed within the first groove 9 via ball bearings, allowing it to slide away from the main shaft 3. This, along with the third sleeve rod 8, moves away from the main shaft 3 and is pulled out from the center of the curled hose, thus preventing the hose end from being continuously clamped by the third sleeve and the fixing rod 5, reducing localized stress. The ball bearings sliding within the first groove 9 facilitate rotation of the second sleeve rod 7 relative to the end of the first sleeve rod 6. After a 90-degree rotation, the second sleeve rod 7 is vertically positioned, serving to limit its movement on the side of the curled hose, preventing it from loosening, and transferring the third sleeve rod 8 to the outer layer of the curled hose. Furthermore, the second sleeve rod 7 has a second groove 12 along its axial direction. A second ball bearing 13 is slidably disposed within the second groove 12 and fixedly mounted on the second end piece 14. The second end piece 14 is fixedly mounted on the end of the third sleeve rod 8, and the other end of the third sleeve rod 8 is movably connected to the fixing plate 2 via a connecting structure.

[0026] The third rod 8 can rotate via the second ball bearing 13. After the second rod 7 rotates to a horizontal position, the third rod 8 rotates 90 degrees via the second ball bearing 13 to reach a horizontal position. Figure 1 After being rotated to a horizontal position, the third sleeve rod 8 is set outside the water hose. Then, the setting position of the third sleeve rod 8 is fixed by the connecting structure. At this time, the end of the water hose can be pressed to prevent it from loosening without external force.

[0027] like Figure 4 As shown, specifically, the connection structure includes an end post 15, a slot 16, and an insert post 17. The end post 15 is fixedly installed at the end of the third sleeve rod 8 away from the main shaft 3. A limit hole is provided on the end post 15. The slot 16 is provided through the fixed plate 2. When the third sleeve rod 8 rotates to a horizontal state, the limit hole on the end post 15 is aligned with the slot 16. An insert post 17 is provided on the other side of the slot 16. The insert post 17 is inserted into the limit hole through the slot 16 to fix the position of the third sleeve rod 8 after rotation. By applying it to a single water hose or a water hose of a fixed length, the other end of the water hose is always near the slot 16 after winding, so that the third sleeve rod 8 can be accurately pressed against the end of the water hose.

[0028] In addition, such as Figure 1As shown, to improve the clamping force of the third sleeve rod 8, a straight groove through hole is further provided at the slot 16. The straight groove through hole has a certain length and is set towards the fixed axis. The length direction of the straight groove through hole is perpendicular to the first sleeve rod 6. The insert 17 can slide in the straight groove through hole to clamp the end of the water hose. When the third sleeve rod 8 rotates to a horizontal state, it slides in the second slide groove 12 through the second ball 13. At this time, the insert 17 slides in the slot 16, thereby pressing the end of the water hose down from top to bottom for clamping.

[0029] Furthermore, to facilitate the setting and operation of the insertion post 17, the insertion post 17 is fixedly mounted on the slide rod 18, and the slide rod 18 is slidably mounted on the operating rod 4 along the axial direction of the operating rod 4. Thus, the slide rod 18 can both slide and displace the insertion post 17, and also serve as an extension of the slide rod 18 to assist the operator in holding it, making the use process more convenient.

[0030] In addition, such as Figure 4 As shown, a transverse groove through hole 19 is provided on the operating rod 4. The slide rod 18 is slidably disposed in the transverse groove through hole 19 along its own axis. A limit piece 20 is provided at the end of the slide rod 18 to prevent it from sliding out of the transverse groove through hole 19. By moving the slide rod 18 axially in the transverse groove through hole 19, the height of the insertion post 17 can be adjusted, so that it can be inserted more accurately into the limit hole.

[0031] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
