When a component is considered to be "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1-3, a schematic structure diagram of a movable holder assembly according to a preferred embodiment of the utility model is shown. In the embodiment shown in fig. 1, a movable clamping seat 1 is used for clamping objects to be clamped, and can be widely applied to various clamping occasions, such as the fields of mechanical manufacturing, assembly, repair and the like. The movable clamp holder 1 comprises a guide bar 15, a sliding connecting block 10, a movable clamp block 11 and an elastic piece 13.

The slide connection block 10 is a base portion of the clamp to support other components, is slidably mounted to the guide bar 15 in a length direction of the guide bar 15, and the movable clamp block 11 is a main clamping portion of the clamp, a first end of which is rotatably mounted to the slide connection block 10.

The movable clamping block 11 is made of a conductor and is rotatably mounted on the sliding connection block 10, the movable clamping block 11 extends along a first direction far away from the rotation axis of the movable clamping block to form a first flow guiding part, the surface of the first flow guiding part facing the clamped object forms a first flow guiding surface 11-2, and the first flow guiding surface 11-2 is used for clamping the clamped object through the pressure applied by the elastic piece 13 and is in contact with the object surface of the clamped object.

The elastic member 13 is a member for transmitting a clamping force to the movable clamp block 11, and is located between the sliding connection block 10 and the movable clamp block 11, for providing the clamping force such that the first guide surface 11-2 closely fits the first clamping surface of the clamped object located on the guide bar 15, typically a spring or a leaf spring or a rubber pad.

When the sliding connection block 10 is driven to move on the guide bar 15 and contact the clamped object, the clamped object is in surface contact with the second guide surface 11-1 of the movable clamping block 11, the movable clamping block 11 rotates in the process (around the pin shaft 12 in the anticlockwise direction in fig. 2) under the elastic restoring force of the elastic element 13, the first guide surface 11-2 contacts with the other side surface of the clamped object, and finally the first guide surface 11-2 is tightly attached to the clamping surface of the clamped object, that is, the first guide surface 11-2 is in surface contact with the clamped object, rather than in point contact or line contact, so that a stable clamping state is formed. In the clamping process, due to the action of the elastic piece 13, the movable clamping block 11 keeps certain elasticity and can freely rotate around the pin shaft 12 along with the shape of the clamping surface of the clamped object until the first guide surface 11-2 is tightly attached to the clamping surface, so that the clamping object clamping device can adapt to the clamped objects with different sizes and shapes and ensure the consistency of clamping force.

As described above, the first diversion surface 11-2 is in surface contact with the clamping surface, so that a larger contact area is ensured, and when the embodiment of the utility model is applied to drainage of railway rails, power grids and the like, the first diversion surface 11-2 is closely attached to the upper side surface of the railway rails or a certain surface of a conductor of the power grid, so that the safety of drainage operation can be ensured when the railway rails, the power grids and the like are electrified and overhauled.

When the clamped object is a steel rail, if the clamping force is uneven or the contact surface is insufficient when the movable clamping seat 1 is used for clamping, arc discharge is easily generated at the contact point, so that an electric spark phenomenon is caused. The electric spark is the phenomenon that the current breaks through the insulating layer at the electric contact point to form electric spark and instantaneously discharge. When the clamping force is concentrated in a small area, high temperature is formed at the contact point, the metal structure of the steel rail surface is further damaged, and adverse effects such as ablation and deformation are generated.

The movable clamping seat 1 with surface contact can effectively avoid the generation of electric spark and avoid the adverse effects of ablation, deformation and the like of the surface of the steel rail caused by high temperature generated by electric spark. The first diversion surface 11-2 of the movable clamping seat 1 is used for carrying out surface contact on the steel rail, and the elastic piece 13 drives the steel rail to realize that the clamping force is uniformly distributed on the contact surface. The mode can reduce heat concentration of the contact surface, and effectively avoid arc discharge, thereby avoiding electric ignition. Meanwhile, the surface contact clamping mode can also protect the surface of the clamped object from being adversely affected by scratch, damage and the like, and the service life and safety of the steel rail are improved.

In some embodiments, the movable clamping block 11 extends along a second direction away from the rotation axis of the movable clamping block to form a second guiding portion, the second guiding portion forms a second guiding surface 11-1 towards the surface of the clamped object, and the second guiding surface 11-1 closely fits with a second clamping surface of the clamped object located on the guide bar 15 under the action of the clamping force of the elastic member 13. The second guiding surface 11-1 is a surface abutting against the clamped object, and the first guiding surface 11-2 is a surface contacting with the clamped object by applying pressure to clamp the clamped object through the elastic member 13.

Fig. 1 and 2 show that the first guide surface 11-2 and the second guide surface 11-1 can be respectively and closely attached to the first clamping surface and the second clamping surface of the clamped object under the clamping force of the elastic member 13; the first diversion surface 11-2 and the second diversion surface 11-1 are similar to the shape of the clamped object. For example, the first guide surface 11-2 is in the shape of a flat slope, and correspondingly, the clamping surface is a flat surface; of course, those skilled in the art can also design the shape of the first guiding surface 11-2 correspondingly according to the shape of the clamping surface, such as the two being mutually matched steps or arcs.

According to the example of the present disclosure, the movable clamp block 11 and the sliding connection block 10 are rotatably arranged through the pin shaft 12, and include a rotation hole 11-3 for accommodating the pin shaft 12, and the rotation hole 11-3 has a floating space for accommodating the movable clamp block 11 in the height direction; the rotation hole 11-3 has a specific shape, for example, the cross section of the rotation hole 11-3 is an ellipse with a long axis extending in the height direction, which provides a floating space for the movable clamp block 11 in the vertical direction, and can be applied to the clamped objects with different thicknesses.

The second guide surface 11-1 of the movable clamping block 11, the first guide surface 11-2 and the guide bar 15 form a jaw 11-4 for fixing the clamped object, and the elastic piece 13 has an elastic force for propping against the movable clamping block to rotate so that the jaw opening is upward. It should be noted that the thickness of the clamped object is greater than the jaw 11-4, and the movable clamping block 11 is subjected to a downward elastic force due to the elastic member 13, so that the clamped object can be clamped firmly.

Under some application scenes, the movable clamping seat 1 in the embodiment can enable the movable clamping block 11 to be in surface contact with the steel rail, when the steel rail is drained, the wiring terminal 14 can be directly arranged on the movable clamping block 11, the wiring terminal 14 is used for being connected with a grounding wire, the inclined surface of the steel rail is a diversion surface in the mode, good drainage effect can be achieved, and the clamped objects are prevented from being burnt.

As shown in fig. 2, the sliding connection block 10 is provided with a sleeve hole 11-5 for accommodating the guide bar 15, and the position of the sliding connection block 10 on the guide bar 15 can be adjusted according to the clamped object.

In addition to the basic structure and clamping process described above, the following are some further details and features of the present utility model:

the design of the elastic member 13 can be adjusted according to actual requirements to ensure clamping strength and stability. For example, different materials, different shapes, or different numbers of spring tabs may be used to achieve the desired spring force. As shown in FIG. 3, the movable clamp block 11 is provided with a mounting opening 11-6 for placing or fixing the spring piece.

The second guide surface 11-1 and the first guide surface 11-2 of the movable clamp block 11 can be designed with different shapes and materials to adapt to the clamped objects with different shapes, sizes and materials. For example, the second flow guiding surface 11-1 may be convex or concave to accommodate round or square shaped objects to be clamped; the first guide surface 11-2 may be made of a wear resistant material to increase the clamping force and stability.

It will be appreciated by those skilled in the art that the specific structure of the movable holder 1 shown in fig. 1-3 is not limiting of the movable holder 1, and that the movable holder 1 may include more or less components than shown, and that certain components may not necessarily be included in the movable holder 1, and may be omitted entirely or combined as desired within the scope of not changing the essence of the utility model.
