Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are described in further detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.

At the field, the valves on the christmas tree are typically connected to the pipeline by a clamp, as shown in fig. 1, which comprises: two opposite arc-shaped bodies 1, a bolt 2 and a nut 3 for connecting the two arc-shaped bodies 1. When the valve is applied, the two arc-shaped bodies 1 are used for clamping the connecting part of the valve and a pipeline, then the bolt 2 is sequentially inserted into the two arc-shaped bodies 1, and the nut 3 is screwed.

The embodiment of the utility model provides a clamp fastening tool, as shown in figure 2, figure 3, figure 4 and figure 5, this clamp fastening tool includes: a handle 4 and a hammer head 5 arranged at the end part of the handle 4. The lower end of the hammer 5 is provided with an arc-shaped groove 501 matched with the arc-shaped body 1 of the hoop, and the upper end of the hammer is provided with a wrench groove 502 sleeved on the nut 3. Wherein "adapted" means: the arc-shaped groove 501 is the same as the outer wall of the arc-shaped body 1 of the hoop in shape.

When a valve on a Christmas tree is required to be connected with a pipeline through a clamp, the two arc-shaped bodies 1 are used for clamping the connection part of the valve and the pipeline, then bolts 2 are sequentially inserted into the two arc-shaped bodies 1, and nuts 3 are tightened. Then, the handle 4 is held, the arc-shaped groove 501 of the hammer head 5 is aligned with the outer side surface of the arc-shaped body 1, and the hammer head is knocked inwards. Then, the wrench groove 502 is sleeved on the nut 3, and the nut 3 is continuously screwed, and the above operation is repeated until the clamp connects and fastens the valve and the pipeline.

The embodiment of the utility model provides a clamp fastening tool is through setting up tup 5 to set up the arc wall 501 with the 1 looks adaptation of arc body of clamp at the lower extreme of tup 5, when having guaranteed tup 5 and the contact of arc body 1, arc body 1 atress is even, avoids arc body 1 to warp, damage. Through set up wrench groove 502 in the upper end of tup 5, guaranteed that clamp fastening tool can fastening nut 3 when realizing the effect of strikeing, whole operation process need not change work, has improved the operating efficiency.

In the embodiment of the present invention, as shown in fig. 5, the clamp fastening tool further includes: ratchet 6, deflecting tooth 7, and elastic element 8 and mobile element 9 axially arranged in handle 4. Wherein, the upper portion of tup 5 is hollow structure, and ratchet 6 sets up on the outer wall of spanner groove 502 along circumference. The elastic element 8, the movable element 9 and the steering teeth 7 are in sequence abutted. The steering gear 7 is arranged on the handle 4 in a manner of swinging left and right, and the tooth tips of the clamping teeth 701 at the two ends of the steering gear 7 are symmetrically oriented and used for being clamped in the ratchet 6 in opposite directions under the elastic action of the elastic piece 8.

Here, the "left-right" direction in the "horizontal swing" refers to the left-right direction in fig. 5. The ratchet 6 and the latch 701 at the two ends of the steering tooth 7 are both oblique teeth. When the latch teeth 701 at the two ends of the steering gear 7 are respectively clamped in the ratchet teeth 6 at the left side and the right side, single-phase locking of the ratchet teeth 6 in different directions can be realized.

When the wrench is used, the wrench groove 502 is sleeved on the nut 3, at the moment, if the steering tooth 7 swings to the ratchet 6 on the left side, the handle 4 is rotated in the forward direction, the clamping tooth 701 at the left end of the steering tooth 7 is clamped in the ratchet 6, at the moment, the handle 4 is rotated in the forward direction continuously, the nut 3 can be screwed, after the handle 4 rotates along with the nut 3 by a preset angle, the handle 4 is rotated in the reverse direction, the handle 4 returns to the initial position along the ratchet 6, and the handle 4 is rotated in the forward direction continuously until the nut 3 is screwed completely. Similarly, if the steering gear 7 swings to the right ratchet 6, the working principle is as described above. In the process, when the steering teeth 7 are switched to the left direction and the right direction, the elastic element 8 can drive the movable element 9 to tightly push against the steering teeth 7, so that the latch teeth 701 on the steering teeth 7 can be clamped into the ratchet 6 under the elastic action of the elastic element 8.

Through setting up as above, can realize screwing up nut 3 fast, easy operation, convenient to use has reduced staff's intensity of labour and operating time.

Wherein, the elastic member 8 may be a spring. The movable part 9 can be a steel ball or a top pin.

In order to facilitate the replacement of the handle 4 or the hammer head 5 when damaged, the handle 4 and the hammer head 5 can be detachably connected.

Specifically, a through hole may be provided in the hammer head 5, and the end of the handle 4 may be tapered so as to be firmly caught in the hammer head 5.

Further, in order to prevent the handle 4 from falling off during the operation, as an example, an anti-slip cover may be provided on the handle 4.

Based on the gum cover cost is lower, and antiskid nature is better, can set up the antiskid cover into the gum cover.

As another example, a rough structure may be provided on the handle 4.

The rough structure comprises any one or combination of the following: strip-shaped bulges, point-shaped bulges and arc-shaped bulges.

In order to reduce the weight of the handle 4 and facilitate the use of the worker, the handle 4 may be made of wood. Meanwhile, in order to improve the strength of the hammer head 5, the hammer head 5 may be made of 45 # steel.

To sum up, the utility model discloses when having guaranteed tup 5 and the contact of arc body 1, arc body 1 atress is even, avoids arc body 1 to warp, damage, simultaneously, can realize screwing up nut 3 fast, easy operation, convenient to use has reduced staff's intensity of labour and operating time.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
