Description

Fixture structure with extension arm

This creation relates to a fast fixture structure, especially a fixture structure with an extension arm that is easy to process and can improve the structural strength.

According to the press, there are various quick clamps on the market today. Basically, the quick clamps are provided with two movable clamping jaws, and a positioning mechanism is used in cooperation to enable the quick clamps to be held in the state of holding articles, thereby It is convenient to process this item. Because the fast jaw uses a fixed-length jaw that cannot be adjusted and is suitable for different sizes of objects, two or even multiple openings of different sizes must be used quickly for items of different sizes and thicknesses. The clamp is used by some operators to form a rod body to expand and contract the length of the jaw, thereby achieving the purpose of adjusting the size of the clamping opening. However, if you look at the above-mentioned conventional structure, it is not difficult to find that there are still some shortcomings. The main reason is as follows: if the rod body is not provided with any damping structure, the rod body will be able to expand or contract by itself, making it difficult to maintain the required position of the rod body, which will cause inconvenience in use. When the rod body is provided with a damping structure, although it overcomes the problem that the rod body will slide on its own, it also increases the complexity of its structure, making it difficult to manufacture. Creation of this technical problem to be solved is how to adjust the resistance having the purpose of reducing the effective cost of production reaches the premise.

In view of this, the author has many years of experience in manufacturing development and design of related products. In view of the above goals, after careful design and careful evaluation, he finally has a practical and practical creation.

The technical problem to be solved in this creation is to provide a fixture structure with an extension arm in response to the above-mentioned shortcomings existing in the prior art.

A clamp body is staggered with each other, and two clamping arms are pivotally provided by a shaft. Each of the clamping arms extends a grip to one end, and the clamping arm forms a block at the other end, and the block faces the direction of the axis. A sliding hole is formed, and the sliding hole is formed with an outer opening and an inner opening, and the block is adjacent to the sliding hole through two latches, and the sliding hole adjacent to the outer opening is provided with a hole that does not penetrate the block. In the receiving slot, two clamping jaws each extend with an adjusting rod, and the clamping jaw is passed through the sliding hole of the fixture body by the adjusting rod, so that the adjusting rod presses the latch in a diagonal direction that bears the downward pressure, and the two springs The outside opening is inserted into the accommodating groove, and the spring abuts between the accommodating groove and the adjusting rod.

A blocking member is locked at one end of the adjusting lever away from the jaw, thereby preventing the adjusting lever from being pulled out of the sliding hole.

Wherein, the shaft sleeve is provided with a torsion spring, and both ends of the torsion spring are hooked to the two clamping arms, so that the grip of the clamp body is maintained in a normally open position.

Wherein, a positioning device is installed between the two grips, so that the grips can be fixed at any opening position.

The positioning device includes a base body, a shaft body, a pressure handle and a compression spring. The base body is pivotally connected to the grip at one end, and the shaft body is telescopically provided by the base body. The handle is pivotally connected to the other end, and the pressure handle is sleeved on the shaft body, and one end of the pressure handle is locked on the seat body, and the compression spring is sleeved on the shaft body and presses against the seat body and the pressure body. Between the handles, the pressing handle can be inclined and engaged with the shaft body in an unpressed state.

Wherein, the spring has an olive shape and is provided with a first cone portion and a second cone portion. The first cone portion allows the spring to be easily inserted into the accommodation groove, and the second cone portion can run along the adjusting rod. The telescopic direction swings in the same direction, thereby increasing the spring resistance of the adjusting rod in telescopic reversal.

Wherein, the opening of the accommodating groove is opened toward the outer side of the slide hole, so that the spring can be easily inserted into the accommodating groove, and constitutes a demolding angle of the clamp body when the mold is formed.

Wherein, an included angle in a range of 45 degrees to 75 degrees is formed between the position of the center line of the receiving groove and the position of the center line of the sliding hole.

The first main purpose of this creation is that the clamping arm is provided with a sliding hole at the block, and an accommodating slot that does not penetrate the block is opened in the sliding hole adjacent to the outer opening, and the accommodating slot is facing The direction of the outer opening is obliquely arranged, thereby allowing the receiving groove to be demoulded at the outer opening when the fixture body is being produced in a mold, that is, the receiving groove can be integrally formed and processed, thereby reducing the processing steps. It can also improve its structural strength, and at the same time allow the spring to be easily inserted into the accommodation slot, that is, the spring can be used to form an appropriate resistance for the adjustment rod to slide along the slide hole, so as to have both the simplified production steps and the use effect .

The second main purpose of this creation is that the spring is in an olive shape and is provided with the first cone portion and the second cone portion. The first cone portion can be easily inserted into the accommodation groove, and the second cone portion can resist. Pressing on the adjustment lever, when the adjustment lever is retracted, the second cone portion can swing in the same direction along the expansion direction of the adjustment lever, so that relatively small resistance can be formed during the expansion process. When the second tapered portion slides in the opposite direction, the second tapered portion will form a relatively large resistance, and it will not transition to a relatively small resistance state until the second tapered portion swings again toward the direction of the adjustment rod displacement. Therefore, the spring resistance of the adjusting rod during the telescopic reversal is improved, so that a better fixing effect can be obtained when the clamping jaw is not operated for expansion and contraction, and the adjusting rod can be reduced during the sliding process. The spring resistance strengthens its effect.
