Description

TECHNICAL FIELD

[0001] The utility model relates to a hand-held hydraulic breaking hammer and belongs to the technical field of hand-held hydraulic breaking hammer. BACKGROUND

[0002] The hydraulic breaking hammer is a special tool for mining or breaking cement pavement, and the breaking hammer is divided into a hand-held breaking hammer and a hydraulic breaking hammer. The hand-held hydraulic hammer is widely used because of its small size, portability, easy operation and large impact. The existing hand-held breaking hammer is provided with a handle above the rear cylinder, the length of the handle is greater than the diameter of the rear cylinder, and the two free ends of the handle have safety hazards during carrying, carrying or improper use. Therefore, it is crucial to develop a hand-held hydraulic breaking hammer with safety. SUMMARY

[0003] The utility model provides a hand-held hydraulic breaking hammer in view of the deficiency existing in the prior art.

[0004] The utility model solves the technical problems in the prior art as follows:

[0005] A hand-held hydraulic breaking hammer comprises a front cylinder, a middle cylinder and a rear cylinder connected in sequence, the rear cylinder is provided with a rear handle above, the rear handle is a hollow structure connected at the front and rear ends, and the side edges of the middle cylinder and the rear cylinder are provided with symmetrically arranged side handles.

[0006] Further, the front cylinder is provided with a stop block for fixing a drill rod.

[0007] Further, the stop block is provided with a round pin detachably connected with the stop block, and the round pin penetrates the stop block and the front cylinder respectively.

[0008] Further, the stop block is detachably connected with the front cylinder.

[0009] Further, the length of the rear handle is the same as the diameter of the rear cylinder.

[0010] Further, the side handles are detachably connected with the side edges of the middle cylinder and the rear cylinder respectively.

[0011] Further, the rear handle is detachably connected with the rear cylinder.

[0012] Compared with the prior art, the utility model has the advantages that the rear handle with the hollow structure connected at the front and rear ends effectively avoids the safety hazards during carrying, carrying or improper use, the symmetrically arranged side handles expand the application scenarios, the rear handle combined with the side handles facilitates the switching use of various application scenarios, and the stop block combined with the round pin adjusts the connection between the front cylinder and the drill rod more stably.

[0017] The principles and features of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and not used to limit the scope of the utility model.

[0018] As Figs. 1-3 Indicated, a handheld hydraulic breaking hammer, including the front cylinder 1, middle cylinder 2 and rear cylinder 3 that are connected in sequence, the rear handle 4 is provided on the rear cylinder 3, and the rear handle 4 is a hollow structure connected at the front and rear ends, and the side edges of the middle cylinder 2 and the rear cylinder 3 are provided with symmetrically arranged side handles 5. When applied, the rear handle 4 is selected according to the requirements of the application scene, or the symmetrically arranged side handles 5 are selected, the rear handle 4 is a hollow structure connected at the front and rear ends, the central position is convenient for holding, and the side handles 5 on both sides are used for holding on both sides.

[0019] The front cylinder 1 is provided with a stop block 8 for fixing the drill rod 6. The connection with the drill rod 6 is effectively adjusted or replaced through the stop block 8.

[0020] The stop block 8 is provided with a round pin 7 detachably connected with the stop block 8, and the round pin 7 penetrates the stop block 8 and the front cylinder 1 respectively. The round pin 7 is used to adjust the stable connection between the front cylinder 1 and the drill rod 6.

[0021] The stop block 8 is detachably connected with the front cylinder 1.

[0022] The length of the rear handle 4 is the same as the diameter of the rear cylinder 3. The safety hazard problem existing in the two free ends of the existing handle can be effectively avoided.

[0023] The side handle 5 is detachably connected with the side edges of the middle cylinder 2 and the rear cylinder 3 respectively. The detachable connection is convenient for the safety of carrying and storing.

[0024] The rear handle 4 is detachably connected with the rear cylinder 3.

[0025] The hollow structure connected with the front end and the rear end effectively avoids the hidden danger problems in the process of carrying, carrying or improper use, the application scene is expanded through the symmetrically arranged side handle 5, the rear handle 4 is combined with the side handle 5, and the switching use of various application scenes is facilitated, and the connection of the front cylinder 1 and the drill rod 6 is more stable through the stop block 8 combined with the round pin 7.

[0026] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
