Description

Technical Field

[0001] The utility model belongs to the technical field of vibrators, and in particular relates to a back-carrying concrete vibrator. Background Art

[0002] An insert vibrator is a mechanical vibration device, mainly used for compaction during the concrete solidification process. According to its working principle and application scenario, it can be mainly divided into two categories: internal vibration type and external vibration type. Internal vibration vibrators usually use diesel engines or electric motors as power, and their vibration components are directly inserted into the concrete for vibration; while external vibration vibrators usually vibrate on the surface of the concrete. In the existing technology, concrete vibrators generally require users to hold the vibrator hose to control the position of the vibrating head. This method is easy to cause the hand to slip due to vibration, causing safety hazards. On the other hand, the vibration force is directly transmitted to the user's arm, increasing the risk of vibration disease. Utility Model Content

[0003] In response to the above problems, the purpose of the present utility model is to provide a back-mounted concrete vibrator, which greatly reduces the impact of the vibration generated by the spiral metal hose inside the vibrator hose during operation on the user. On the one hand, it improves the stability of the control over the position of the vibrator hose and the vibrator head, and reduces the possibility of slipping out of the hand. Even if it slips out of the hand, under the action of gravity, the vertical rod together with the second L-shaped rod, the telescopic adjustment rod, and the rubber handle will directly rotate and move downward, so that the vibrator head will directly hit the ground, and cooperate with the limitation of the vibrator hose, so that the vibrator head and the vibrator hose will not swing out of control and cause injury, thereby improving safety and reducing the occurrence of vibration disease.

[0004] To achieve the above objectives, the utility model provides the following technical solutions: a back-type concrete vibrator, comprising a back plate, the top and bottom of the back plate being connected with a shoulder strap, the back of the back plate being provided with a supporting plate, the top of the supporting plate being equipped with a battery compartment, the bottom of the supporting plate being provided with a first bearing seat, the bottom of the first bearing seat being rotatably connected to the first L-shaped rod, one end of the first L-shaped rod being connected to the second bearing seat, the second bearing seat being rotatably connected to the second L-shaped rod, one end of the second L-shaped rod being inserted and connected to the telescopic adjustment rod, the top of the second L-shaped rod being provided with a screw hole and a locking bolt being threadedly installed thereon, one end of the telescopic adjustment rod being provided with a rubber grip, one end of the rubber grip being connected to a pin connection seat, a vertical rod being pin-connected to the pin connection seat, a hose limit seat being provided on the side of the vertical rod, a vibrator motor being installed on the top of the battery compartment, the output end of the vibrator motor being connected to the vibrator rod hose, the vibrator rod hose passing through the hose limit seat, and the other end of the vibrator rod hose being connected to the vibrator head.

[0005] The beneficial effects of the present invention are as follows: when the device is in use, the device is carried on the back via the shoulder strap, and the user holds the rubber handle with his right hand to perform the vibrating work on the concrete. The operation of the vibrator motor is controlled by the switch button on the top of the rubber handle, and the power is transmitted through the spiral metal hose in the vibrating rod hose to drive the vibrating head to vibrate at high frequency. Since the rear half of the vibrating rod hose is fixed to the side of the vertical rod through the hose limit seat, and the vertical rod and the rubber handle are pin-connected by the pin connection seat, the vertical rod can be kept in a vertical state under the action of gravity. The user can rotate the second L-shaped rod, the telescopic adjustment rod and the rubber handle downward through the second bearing seat to press the vertical rod downward to insert the vibrating head into the concrete for vibration, and the telescopic adjustment rod can be telescopically adjusted. After the adjustment is completed, tighten the locking bolt to tighten the second L-shaped rod and the telescopic adjustment rod. It can be locked in one row, so it is suitable for users with different arm lengths. Since the user does not directly hold the vibrator hose, compared with the existing method of directly holding the vibrator hose to grasp the position of the vibrator head and lift and lower it, the vibration generated by the spiral metal hose inside the vibrator hose during operation is greatly reduced. The impact on the user is improved on the one hand, and the stability of the control of the position of the vibrator hose and the vibrator head is improved, and the situation of slipping out of the hand is reduced. Even if it slips out of the hand, under the action of gravity, the vertical rod together with the second L-shaped rod, the telescopic adjustment rod, and the rubber handle will directly rotate and move downward, so that the vibrator head is directly hit on the ground, and cooperate with the limitation of the vibrator hose, so that the vibrator head and the vibrator hose will not swing out of control and cause injury, thereby improving safety and reducing the occurrence of vibration disease.
