Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of engineering equipment, specifically a hand-push type tube winding frame bushing locking device. Background Technology
[0002] The hand-push type tube winding carriage frame bushing locking device is made of plastic or other metal materials and is a device that can bear, fix and guide the moving device. The hand-push type tube winding carriage frame bushing locking device is used to guide and fix the tie rod component.
[0003] Some hand-push type tube winding frame bushing locking devices mainly use a screw to lock the plastic tube. After the push rod is inserted into the bushing, the screw is rotated to press against the side wall of the push rod, thereby fixing the push rod.
[0004] However, during operation, the hand-push tube winding cart needs to be frequently pushed to different environments. Due to the small area of the sliding sleeve tube body for clamping and positioning, the push rod is prone to running after locking.
[0005] Based on this, in order to reduce the movement of the push rod, this utility model designs a hand-push type winding tube frame bushing locking device to solve the above problems. Utility Model Content
[0006] To achieve the above objectives, this utility model provides the following technical solution: a hand-push type tube-wrapped frame bushing locking device, comprising a frame, a bushing mounted on the frame, and a push rod inserted into the bushing. The bushing is provided with a fixing assembly for fixing the push rod. The fixing assembly includes a first arc-shaped plate, a second arc-shaped plate, a connecting shaft, and a retaining block. One end of the first arc-shaped plate and the second arc-shaped plate are connected to each other, forming a cylindrical shape. A connecting plate is fixedly mounted on the first arc-shaped plate, and a fixing plate is fixedly mounted on the second arc-shaped plate. A connecting hole is provided on the connecting plate, and a clearance hole is provided on the fixing plate. The connecting shaft passes through the clearance hole and the connecting hole. An anti-disengagement ring is threaded onto the connecting shaft. The retaining block is rotatably mounted on the connecting shaft and is an eccentric block. When the push rod is located on the bushing, the first arc-shaped plate and the second arc-shaped plate clamp the push rod. At this time, the end of the retaining block farther from the rotation center abuts against the fixing plate.
[0007] By adopting the above technical solution, after the push rod is inserted into the bushing, the clamping block is moved. The end of the clamping block that is farther away from the rotation center abuts against the fixed plate, thereby bringing the first arc plate and the second arc plate closer to each other, clamping the push rod, increasing the contact area with the push rod, and making the clamping more sufficient, thus reducing the push rod's movement.
[0008] Preferably, an abutment spring is sleeved on the connecting shaft, and the abutment spring is located between the fixed plate and the connecting plate.
[0009] By adopting the above technical solution, when it is necessary to remove the push rod, the clamping block is released. At this time, the abutment spring abuts against the first arc plate and the second arc plate, which facilitates the separation of the first arc plate and the second arc plate and makes it easy to remove the push rod.
[0010] Preferably, the fixing plate has a clearance groove.
[0011] By adopting the above technical solution, the presence of a clearance groove can reduce the movement of the abutment block.
[0012] Preferably, a lever is fixedly provided on the abutting block.
[0013] By adopting the above technical solution, when it is necessary to rotate the clamping block, the clamping block can be rotated quickly and easily by moving the lever.
[0014] In summary, this application has the following beneficial technical effects: after the push rod is inserted into the bushing, the clamping block is moved, and the end of the clamping block that is far from the rotation center abuts against the fixed plate, thereby bringing the first arc plate and the second arc plate closer to each other, clamping the push rod, increasing the contact area with the push rod, and making the clamping more sufficient, thereby reducing the push rod's movement.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0025] Reference Figures 1-5 A hand-push type tube-wrapping frame bushing locking device includes a frame 1, a bushing 2 disposed on the frame 1, and a push rod 3 inserted into the bushing 2. The bushing 2 is provided with a fixing component for fixing the push rod 3. The fixing component includes a first arc plate 4, a second arc plate 5, a connecting shaft 6, and a clamping block 7. One end of the first arc plate 4 and the second arc plate 5 are connected to each other. In this embodiment, the first arc plate 4 and the second arc plate 5 are made of plastic and have a certain toughness. A connecting plate 8 is fixedly disposed on the first arc plate 4, and a fixing plate 9 is fixedly disposed on the second arc plate 5. A connecting hole 10 is opened on the connecting plate 8, and a clearance hole 11 is opened on the fixing plate 9. The connecting shaft 6 passes through the clearance hole 11 and the connecting hole 10. An anti-detachment ring 12 is threadedly connected to the connecting shaft 6. The clamping block 7 is rotatably disposed on the connecting shaft 6 and is an eccentric block.
[0026] Reference Figures 1-5 The fixed plate 9 has a clearance groove 13. When the push rod 3 is on the bushing 2, the first arc plate 4 and the second arc plate 5 clamp the push rod 3. The first arc plate 4 and the second arc plate 5 form a cylindrical shape, and there is a gap between the unconnected sides of the first arc plate 4 and the second arc plate 5. The abutment block 7 is moved so that the side of the abutment block 7 that is farther from the rotation center abuts against the groove wall of the clearance groove 13, so that the anti-detachment ring 12 drives the connecting plate 8 to deflect towards the fixed plate 9. At the same time, the fixed plate 9 deflects towards the connecting plate 8, so that the first arc plate 4 and the second arc plate 5 fully clamp the push rod 3, increase the contact area with the push rod 3, and make the clamping more sufficient, thereby reducing the movement of the push rod 3.
[0027] Reference Figures 1-5According to the size of the push rod 3, the position of the anti-detachment ring 12 is adjusted to adjust the clamping strength of the first arc plate 4 and the second arc plate 5, which is convenient for using push rods 3 with similar pipe diameters. The relief groove 13 can reduce the movement of the clamping block 7. When the first arc plate 4 and the second arc plate 5 are loosened, the clamping block 7 is rotated so that the side closer to the rotation center abuts against the groove wall of the relief groove 13, so that the anti-detachment ring 12 no longer abuts against the connecting plate 8, and the clamping block 7 no longer abuts against the fixing plate 9, thereby allowing the first arc plate 4 and the second arc plate 5 to loosen from each other.
[0028] Reference Figures 1-5 A retaining spring 14 is sleeved on the connecting shaft 6. The retaining spring 14 is located between the fixed plate 9 and the connecting plate 8. When the push rod 3 needs to be removed, the retaining block 7 is released. At this time, the retaining spring 14 abuts against the first arc plate 4 and the second arc plate 5, which facilitates the separation of the first arc plate 4 and the second arc plate 5, making it easy to remove the push rod 3. A lever plate 15 is fixedly installed on the retaining block 7. The lever plate 15 is integrally formed with the retaining block 7. When the retaining block 7 needs to be rotated, the retaining block 7 can be rotated quickly and easily by lever plate 15.
[0029] The implementation principle of this embodiment is as follows: After the push rod 3 is inserted into the bushing 2, the clamping block 7 is moved so that the side of the clamping block 7 that is farther from the rotation center abuts against the groove wall of the relief groove 13, so that the anti-detachment ring 12 drives the connecting plate 8 to deflect towards the fixed plate 9. At the same time, the fixed plate 9 deflects towards the connecting plate 8, so that the first arc plate 4 and the second arc plate 5 fully clamp the push rod 3, increase the contact area with the push rod 3, and make the clamping more sufficient, thereby reducing the movement of the push rod 3.
