Description

Technical Field

[0001] The utility model relates to the field of building construction equipment, in particular to a vibrating rod. Background Art

[0002] A vibrating rod is a necessary tool for concrete construction. The vibrating rod generally includes a motor and an eccentric block fixed on the output shaft of the motor, such as the vibrating rod disclosed in patent document No. CN107338961A.

[0003] The vibration of the existing vibrating rod is unilateral vibration, and the vibration block is only arranged on one side of the motor close to the vibration head. This form leads to poor vibration effect. Utility Model Content

[0004] Aiming at the above problems, the utility model provides a vibrating rod.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A vibrating rod, comprising:

[0007] case;

[0008] A motor is installed in the housing, the motor has a rotating shaft, and the rotating shaft has a first end and a second end;

[0009] A first eccentric vibrating member is rotatably mounted in the housing and is located at one side of the first end of the rotating shaft. The first end of the rotating shaft is directly or indirectly connected to the first eccentric vibrating member. When the motor is working, the first eccentric vibrating member is driven to rotate.

[0010] The second eccentric vibrating member is rotatably mounted in the housing and is located at one side of the second end of the rotating shaft. The second end of the rotating shaft is directly or indirectly connected to the second eccentric vibrating member. When the motor is working, it drives the second eccentric vibrating member to rotate.

[0011] In the prior art, the eccentric vibrator of the vibrating rod used for concrete construction is only arranged at one end of the motor, which causes the vibration source to be distributed only at the lower end of the shell, resulting in poor vibration effect. The present application respectively arranges the first eccentric vibrator and the second eccentric vibrator at both ends of the motor to effectively improve the vibration effect.

[0012] In addition, compared with the existing motor that is subjected to unilateral force, the first eccentric vibrating member and the second eccentric vibrating member can better release the motor performance.

[0013] In one embodiment of the utility model, a first mounting seat is further installed in the housing, and the second eccentric vibrating member is rotatably mounted on the first mounting seat. In actual use, there are at least two first mounting seats, and a bearing is installed on the first mounting seat, and the two ends of the second eccentric vibrating member are respectively matched with the bearings of the two first mounting seats.

[0014] In one embodiment of the utility model, one end of the shell has a head and the other end is a tail end, the first end of the rotating shaft faces the head, and the second end of the rotating shaft faces away from the head, the first mounting seat has a limiting hole, the motor has a wire extending to the tail end of the shell, and the limiting hole is used for the wire of the motor to pass through.

[0015] The eccentric vibrating parts on both sides of the motor will make it difficult to arrange the wires. In this application, limiting holes are set on the first mounting seat to allow the wires of the motor to pass through and limit the guide.

[0016] In one embodiment of the present invention, the limiting hole is located on the outer periphery of the first mounting seat. This arrangement can make the housing and the structure inside the housing more compact.

[0017] In one embodiment of the utility model, it also includes a spacer sleeve located between the two first mounting seats, the second eccentric vibrating member is located in the spacer sleeve, and the side wall of the spacer sleeve has a strip-shaped limiting groove, and the strip-shaped limiting groove is used for the wire of the motor to pass through.

[0018] The spacer can effectively prevent the second eccentric vibrator from contacting the wire when rotating, and the strip-shaped limit groove can effectively limit the wire. The "second eccentric vibrator is located in the spacer" mentioned in the present application is not limited to being completely located in the spacer, and the two ends of the second eccentric vibrator can pass through the end surface of the spacer.

[0019] In one embodiment of the present invention, the strip-shaped limiting groove is located on the outer side wall of the spacer sleeve. This arrangement can make the housing and the structure inside the housing more compact.

[0020] In one embodiment of the utility model, a second mounting seat is further installed in the housing, and the first eccentric vibrating member is rotatably mounted on the second mounting seat. In actual use, there are at least two second mounting seats, and bearings are installed on the second mounting seats. The two ends of the first eccentric vibrating member are respectively matched with the bearings of the two second mounting seats;

[0021] In one embodiment of the utility model, at least two third mounting seats are installed in the housing, and the two ends of the rotating shaft are rotatably mounted on the two third mounting seats respectively. The third mounting seat matched with the second end of the rotating shaft has a limiting hole, and the limiting hole of the third mounting seat is used for the wire of the motor to pass through. In actual use, a bearing is installed on the third mounting seat, and the two ends of the rotating shaft are matched with the bearings of the two third mounting seats respectively.

[0022] The present application is configured in such a way that the wire coming out of the motor can be limited by the limiting holes and the limiting grooves, and extend to the tail end along the inner wall of the shell. This not only has little impact on the structure, but also can ensure the reliable operation of the wire, and the second eccentric vibrator will not interfere with it.

[0023] In one embodiment of the present invention, the first end of the rotating shaft is connected to the first eccentric vibrating member via a coupling; the second end of the rotating shaft is connected to the second eccentric vibrating member via a coupling.

[0024] It should be noted that when connected to the eccentric vibrator through a coupling, the shaft of the coupling connected to the end of the second eccentric vibrator directly cooperates with the bearing of the first mounting seat, and the end of the second eccentric vibrator does not directly cooperate with the bearing of the first mounting seat, which also belongs to the situation where the two ends of the second eccentric vibrator respectively cooperate with the bearings of the two first mounting seats mentioned in the present application, and the shaft of the coupling connected to the second end of the rotating shaft directly cooperates with the bearing of the third mounting seat, and the second end of the rotating shaft does not directly cooperate with the bearing of the third mounting seat, which also belongs to the situation where the rotating shaft cooperates with the bearing of the third mounting seat mentioned in the present application.

[0025] In one embodiment of the present invention, the housing includes a plurality of threaded sleeves and a plurality of hollow cylindrical sub-shells arranged in sequence from head to tail, and the head is threadedly connected to the end of the adjacent sub-shell;

[0026] The threaded sleeve is located at the connection between two adjacent sub-shells, and the threaded sleeve is located inside the two adjacent sub-shells and is threadedly connected with the two sub-shells.

[0027] Such arrangement of the housing facilitates assembly and maintenance.

[0028] In one embodiment of the present invention, the head is a bullet head structure.

[0029] The beneficial effect of the utility model is that the eccentric vibrator of the vibrating rod used for concrete construction in the prior art is only arranged at one end of the motor, which causes the vibration source to be distributed only at the lower end of the shell, and the vibration effect is poor. The present application respectively arranges the first eccentric vibrator and the second eccentric vibrator at both ends of the motor to effectively improve the vibration effect.
