[0002] When connecting rod-shaped components of construction machinery, a common connection method is to use flanges, which has the effect of quick installation.

[0003] In the process of implementing the solution, the inventors found that the following problems in the prior art have not been well solved: since the rods are relatively long, and although there are flange assemblies at the joints for splicing, if the force applied to the rods is too large, the stability of the two rods simply relying on the flange assembly for connection will be greatly reduced, thus posing certain safety hazards.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The present application has both unilateral stabilization effect and bilateral stabilization effect, which can be selected according to the needs of the user. The two clamps are installed on the positioning rod through bolt assembly 2 to stably connect the basic parts. The two positioning rods have two basic parts, and the two basic parts are respectively connected to the reinforcement rod through a connecting mechanism, so that the positioning rods can not only be fastened through the connecting plate, but also can achieve a secondary fastening effect through the reinforcement rod, the connecting mechanism, the clamp and the bolt assembly 2, which not only increases the stability of the connection, but also can adjust the connection mechanism and the clamp to fix the position of the positioning rod according to the reinforcement rods of different lengths, so that the present device has a better fastening effect.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4As shown, a fastening device for connecting engineering machinery includes a positioning rod 1. The number of the positioning rods 1 is two. A connecting plate 2 is provided at one end of the positioning rods 1 that is close to each other. A bolt assembly 3 is provided at the four corners between the connecting plates 2. The four corners between the connecting plates 2 are detachably connected by the bolt assembly 3. A clamp 6 is sleeved on the outer walls of both ends of the positioning rod 1. A plurality of bolt assemblies 7 are provided between the two transversely parallel clamps 6. The clamps 6 are detachably connected by the bolt assemblies 7 respectively. A reinforcement rod 4 is provided on one side between the positioning rods 1. A connecting mechanism 5 is provided at the top and bottom ends of the reinforcement rod 4. The connecting mechanism 5 includes a rotating seat 51 and a sleeve 54. A threaded rod 55 is fixed to the outer wall of one end of the sleeve 54. An extrusion screw 56 is threadedly connected to the outer wall of the other end of the sleeve 54. An internal threaded cylinder 52 is rotatably connected to one end of the rotating seat 51.

[0022] Specifically, the sleeve 54 is sleeved on the outer wall of the reinforcing rod 4 , and one end of the extrusion screw 56 inserted into the sleeve 54 contacts the outer wall of the reinforcing rod 4 , so that the sleeve 54 can be limited to a suitable height on the reinforcing rod 4 .

[0023] Specifically, an end of the rotating seat 51 away from the internal threaded tube 52 is provided with an outer wall of the clamp 6, and a hexagonal block 53 is fixed to the outer wall of the internal threaded tube 52 to facilitate the rotation of the internal threaded tube 52 so that it can be threadedly connected with the threaded rod 55.

[0024] Specifically, the threaded rod 55 is inserted into the interior of the internal threaded tube 52 and threadedly connected thereto, connecting the clamp 6 and the reinforcement rod 4 together according to the spacing.

[0025] Specifically, the material of the reinforcing rod 4 is the same as that of the positioning rod 1, so as to increase the hardness during tightening.

[0026] Working principle:

[0027] Unilateral fastening state: each positioning rod 1 has two clamps 6, and only one clamp 6 is connected to a reinforcement rod 4 through a connecting mechanism 5. This is a unilateral fastening state;

[0028] Double-sided fastening state: each positioning rod 1 has two clamps 6, and the two clamps 6 are respectively connected to the reinforcement rod 4 through the connecting mechanism 5. In this state, there are two reinforcement rods 4, which is a double-sided fastening state;

[0029] The single-side fastening state and the double-side fastening state can be regarded as one fastener, and fasteners can be respectively arranged at different heights between the two positioning rods 1 to achieve the required fastening strength;

[0030] During installation, the clamp 6 is sleeved on the positioning rod 1 and limitedly connected through the bolt assembly 27. After the sleeve 54 is sleeved on the reinforcement rod 4 and slides to a position matching the clamp 6, the extrusion screw 56 is rotated so that it is inserted into the sleeve 54 and pressed against the reinforcement rod 4 for limiting. The threaded rod 55 is placed in the position of the hexagonal block 53, and the outer wall of the threaded rod 55 is threadedly connected with the inner wall of the internal threaded tube 52 through the rotation of the internal threaded tube 52 and the rotating seat 51, so as to achieve a stable connection between the clamp 6 and the reinforcement rod 4. The different lengths formed by the threaded connection between the threaded rod 55 and the internal threaded tube 52 can be freely adjusted, thereby adjusting the spacing between the positioning rod 1 and the reinforcement rod 4, and avoiding some slightly larger connecting plates 2 from affecting the installation of the device.

[0031] The circuits, electronic components and control modules involved are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to software and methods.
