Description

Technical Field

[0001] The utility model relates to the technical field of concrete compacting equipment, in particular to a vibrator used for concrete. Background Art

[0002] Insert vibrator, also known as concrete vibrator, is used to cast concrete components with concrete mixers. It is necessary to remove air bubbles and perform compaction to make the concrete dense and eliminate the honeycomb and pockmarked surface of the concrete, so as to improve its strength and ensure the quality of concrete components. Concrete vibrator is a device that uses power through a certain device as a vibration source to generate frequent vibrations, and transmits this vibration to the concrete to vibrate and compact the concrete.

[0003] At present, most insertion vibrators have a long vibration hose for flexible movement. The operator can grab a hose of suitable length and move it to the corresponding position to insert it for vibration. However, since the hose itself has a vibration feeling, it is easy to get numb in the hand if held for a long time, and it is easy to slip out of the hand, which is not conducive to long-term construction. However, the prior art with patent number CN211850909U uses a handle to fix the hose, but the position of the handle cannot be moved, which leads to a limited insertion depth of the vibrator on the hose. Utility Model Content

[0004] The purpose of the utility model is to provide a vibrator for concrete to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vibrator for concrete, comprising a hose and a controller installed on the hose; the controller comprises a tube body, a first clamp is provided on one side of the tube body, a second clamp is provided on the other side of the tube body, and the first clamp has the same structure as the second clamp; the first clamp comprises a support rod installed on the outer wall of the tube body and a linkage member slidably matched with the support rod; one end of the linkage member is connected to a first clamping plate, and the other end of the linkage member is connected to a second clamping plate; a pusher is provided to slide on the support rod so that the linkage member drives the first clamping plate and the second clamping plate to approach or move away from the hose.

[0006] As a preferred technical solution of the utility model: a spring is further provided on a side of the linkage member facing the tube body, and the spring causes the linkage member to slide toward a side away from the tube body.

[0007] As a preferred technical solution of the utility model: the linkage member includes a sliding seat that is slidably matched with the support rod, and connecting rods are provided at both ends of the sliding seat.

[0008] As a preferred technical solution of the utility model: the upper end of the connecting rod is connected to the connecting hole on the first clamping plate through a transmission member.

[0009] As a preferred technical solution of the utility model: a rubber tube is sleeved on the outer wall surface of the connecting rod.

[0010] As a preferred technical solution of the utility model: the first clamping plate and the second clamping plate are both arranged in an arc shape, and the first clamping plate and the second clamping plate are both provided with protrusions on one side facing the hose.

[0011] As a preferred technical solution of the utility model: a mounting seat is further provided in the middle of the tube body, and the mounting seat is threadedly matched with the support rod through a screw hole provided therein.

[0012] As a preferred technical solution of the utility model: a guide seat is further provided on the tube body, and a through hole connected to the inside of the tube body is also provided on the guide seat.

[0013] By adopting the above technical solution, the beneficial effect of the utility model is that when the push part slides toward the tube body, the two clamps are used to clamp the hose inside the tube body at the same time to enhance the controller's control over the hose, and when the push part slides outward, the two clamps are away from the hose to facilitate the controller to release the hose. Based on this, the position of the controller on the hose can be easily and conveniently adjusted so that the hose and the vibrating rod on the hose can penetrate into the concrete. In particular, the push part is used to realize the two clamps to move toward or away from each other, so that the two clamps on the two clamps can synchronously clamp the hose or release the hose, and then the contact point with the hose can be expanded during clamping to enhance the reliability after connection with the hose.

DETAILED DESCRIPTION

[0022] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0023] See also Figure 1-7 , the utility model provides an embodiment: a vibrator for concrete, comprising a hose 1, a controller 2 installed on the hose 1; the controller 2 comprises a tube body 20, a first clamp 21 is provided on one side of the tube body 20, a second clamp 22 is provided on the other side of the tube body 20, and the first clamp 21 and the second clamp 22 have the same structure; the first clamp 21 comprises a support rod 25 installed on the outer wall of the tube body 20 and a linkage member 24 slidably matched with the support rod 25; one end of the linkage member 24 is connected to a first clamping plate 29, and the other end of the linkage member 24 is connected to a second clamping plate 210; the linkage member 24 slides on the support rod 25 through a pusher 26, so that the linkage member 24 drives the first clamping plate 29 and the second clamping plate 210 to approach the hose 1 or move away from the hose 1.

[0024] In summary, when the push part 26 slides toward the tube body 20, the two clamps are used to clamp the hose 1 inside the tube body 20 at the same time, so as to enhance the control ability of the controller 2 over the hose 1. Meanwhile, when the push part 26 slides outward, the two clamps are away from the hose 1, so as to facilitate the controller 2 to release the hose. Based on this, the position of the controller on the hose 1 can be easily and conveniently adjusted, so that the hose 1 and the vibrating rod on the hose 1 can penetrate into the concrete. In particular, the push part 26 is used to realize the two clamps to move toward or away from each other, so that the two clamps on the two clamps can synchronously clamp the hose or release the hose, and then the contact point with the hose can be expanded during clamping, so as to enhance the reliability after the connection with the hose 1.

[0025] Furthermore, since a spring 211 is provided on the side of the linkage member 24 facing the tube body 20, and the spring 211 forces the linkage member 24 to slide toward the side away from the tube body 20, when the pushing portion 26 slides outward, the spring 211 can drive the two splints on the linkage member 24 to slide outward synchronously, so as to realize automatic outward sliding of the splints.

[0026] At the same time, the linkage 24 includes a slide seat 218 that is slidably matched with the support rod 25, and connecting rods 23 are provided at both ends of the slide seat 218. Therefore, the pushing portion 26 is used to contact the slide seat 218, and then the slide seat 218 is used to slide on the support rod 25 to ensure that the first clamping plate 29 and the second clamping plate 210 will not have axial rotation problems when sliding, thereby ensuring that the first clamping plate 29 and the second clamping plate 210 can slide stably and reliably in the direction of the hose 1. Similarly, it can also ensure that the first clamping plate 29 and the second clamping plate 210 can be reliably separated from the hose 1.

[0027] Furthermore, since the upper end of the connecting rod 23 is connected to the connecting hole 216 on the first clamping plate 29 through the transmission member 28, it is convenient to assemble the two clamping plates and the linkage member 24. In addition, the transmission member 28 is used to realize power transmission and the sliding of the transmission member 28 on the tube body 20 is used to further avoid the problem of axial rotation of the first clamping plate 29 and the second clamping plate 210 when sliding; wherein the connecting hole 216 is preferably a screw hole.

[0028] In order to further reduce the problem of numbness in the user's arm caused by the hose 1, a rubber tube 27 is mounted on the outer wall of the connecting rod 23. Therefore, when the user holds the rubber tube 27, the rubber tube 27 absorbs the vibration of the hose 1, thereby reducing the impact of the hose 1 on the user's hand.

[0029] On the basis of the above scheme, since the first clamping plate 29 and the second clamping plate 210 are both arranged in an arc shape, the two clamping plates are more closely attached to the hose 1. At the same time, the first clamping plate 29 and the second clamping plate 210 are both provided with a protrusion 217 on the side facing the hose 1. Therefore, when the two clamping plates are tightly clamped on the hose 1, the setting of the protrusion 217 makes the contact between the clamping plates and the hose 1 more stable and reliable. At the same time, the protrusion 217 can also be used to avoid relative sliding when the two clamping plates are clamped on the hose 1.

[0030] Furthermore, since a mounting seat 212 is provided in the middle of the tube body 20, and the mounting seat 212 is threadedly matched with the support rod 25 through a screw hole 213, the assembly of the support rod 25 and the tube body 20 is also convenient.

[0031] At the same time, a guide seat 214 is also provided on the tube body 20 , and a through hole 215 connected to the inside of the tube body 20 is also provided on the guide seat 214 .

[0032] To sum up, after the first clamping plate 29 and the second clamping plate 210 are first inserted into the tube body 20, the transmission member 28 is then used to pass through the guide seat 214 and connect with the connecting hole 216 on the clamping plate, and then the support rod 25 is connected with the screw hole 213, and before the connection, the spring 211 is placed between the linkage member 24 and the mounting seat 212, and finally the pushing part 26 is installed on the outside of the linkage member 24; wherein, the pushing part 26 and the support rod 25 are also preferably connected in a threaded manner.

[0033] Based on this, when the pushing portion 26 rotates on the support rod 25, the linkage member 24 can be prompted to drive the two clamps to move. At the same time, when the pushing portion 26 and the support rod 25 are threaded, it can be ensured that after the pushing portion 26 moves to the specified position on the support rod 25, there will be no automatic sliding phenomenon, thereby ensuring that after the clamps clamp the hose 1, the clamps will not automatically loosen.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
