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 clamp block assembly according to a preferred embodiment of the utility model is shown. In the embodiment shown in fig. 1, the movable clamp block 1 comprises: the connecting piece 10, the movable block 11 and the elastic piece 13, wherein the connecting piece 10 is a basic part of a clamp for supporting other components, the connecting piece is made of a conductor and is fixed on the conducting bar 2, the movable block 11 is a main clamping part of the clamp, the connecting piece 10 is made of a conductor and is rotatably installed, the movable block 11 extends along a first direction far away from the rotation axis of the connecting piece to form a first diversion part 11-1, and the surface of the first diversion part 11-1 facing the clamped object forms a first diversion surface 11-1a.

The elastic member 13 is a member for transmitting a clamping force to the movable block 11, typically a spring or an elastic pad, and one end of the elastic member 13 is connected to the connection member 10 and the other end is connected to the outer side 11-2a of the movable block 11. When a force is applied to the guide bar 2 at one end away from the movable clamp block 1, the clamped object is clamped on the second guide surface 11-2b of the movable block 11, the movable block 11 rotates in the process (clockwise around the pin shaft mounting hole in fig. 2) under the elastic restoring force of the elastic piece 13, the first guide surface 11-1a is tightly attached to the first clamping surface of the clamped object on the guide bar 2, and finally the first guide surface 11-1a is tightly attached to the clamping surface of the clamped object, that is, the first guide surface 11-1a is in surface contact with the clamped object, rather than 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 block 11 keeps certain elasticity and can freely rotate around the pin shaft mounting hole along with the shape of the clamping surface of the clamped object until the first guide surface 11-1a 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 11-1a 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 11-1a 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 rail is in point or line contact, the current density at the contact point is high, which may cause arcing of the current across the rail surface. Such electrical sparking can lead to high temperatures and oxidative damage, which in turn can lead to damage to the surface and internal structure of the rail. The surface contact can lead the clamping force to be uniformly distributed on the surface of the steel rail, thereby reducing the current density of the contact point and avoiding the occurrence of the phenomenon of electric ignition.

In addition, the surface contact can reduce the relative movement between the steel rail and the clamp, so that abrasion and heat generation caused by friction force and inertia force are avoided. The temperature of the surface of the steel rail can be reduced, the ablation and damage of the surface of the steel rail can be reduced, and the service life of the steel rail can be prolonged. Therefore, the movable clamping block 1 is used for carrying out surface contact clamping on the steel rail, so that the problems of electric ignition, ablation and the like can be effectively avoided, and the service life and the safety of the steel rail are improved.

In some embodiments, the movable block 11 extends along a second direction away from the rotation axis of the movable block to form a second guiding portion 11-2, the second guiding portion 11-2 forms a second guiding surface 11-2b towards the surface of the clamped object, and the second guiding surface 11-2b closely fits with a second clamping surface of the clamped object located on the guide bar 2 under the clamping force of the elastic member 13. The second guiding surface 11-2b is a surface abutting against the clamped object, and the first guiding surface 11-1a 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 11-1a and the second guide surface 11-2b 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 11-1a and the second diversion surface 11-2b are similar to the shape of the clamped object. For example, the first guide surface 11-1a is shaped as 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 11-1a correspondingly according to the shape of the clamping surface, such as the two are mutually matched steps or arcs.

According to the embodiment of the present disclosure, when the connecting member 10 is elastic, for example, when the connecting member 10 is a spring steel plate, the end of the connecting member 10 far away from the conducting bar 2 can be slightly (for example, 2 mm) deformed when being pressed outwards by the selection of materials and the design of structures, so as to adapt to steel rails with different specifications.

Specifically, the connecting piece 10 is formed by folding an elastic plate in opposite directions, and forms a ridge 10-1 at the middle section, an upper supporting part 10-2 and a lower mounting part 10-3 distributed on two sides of the ridge, two sides of the upper supporting part 10-2 are bent to form a lug 10-4 distributed on two sides of the upper supporting part, the movable block 11 is rotatably mounted on the lug 10-4, and the elastic piece 13 is connected with the ridge 10-1 of the connecting piece 10.

In the above embodiment, the elastic member 13 may provide a certain elastic force, but if it is directly fixed to the connecting member 10 as an elastic portion of the entire movable clamp block 1, it is easy to cause damage due to excessive bending of the elastic member 13. Therefore, the present embodiment provides the ridge 10-1 in the connection member 10, provides a smoother elastic force by bending the connection member 10, and provides a connection between the ridge 10-1 and the elastic member 13 to buffer the bending of the elastic member 13, preventing the elastic member 13 from being damaged by excessive force during the bending. Meanwhile, the connecting piece 10 can absorb and disperse partial force when the movable block 11 is acted by external force, so that damage caused by rigid connection of the movable block 11 and the connecting piece 10 is avoided. In addition, by the rotatable movable block 11, the clamping objects with different thicknesses can be suitable.

The movable clamping block 1 has the advantages of simple structure, stable clamping, easy use and the like, and can be widely applied to various clamping occasions besides steel rails, such as the fields of mechanical manufacture, assembly, repair and the like.

The composition and connection relationship of the above components will be specifically described below.

According to the examples of the present disclosure, the connection between the movable block 11 and the tab 10-4 is not limited to the connection by the pin 12.

According to the example of the present disclosure, the outer side surface of the movable block 11 has a spring hole, and when the elastic member 13 is a spring, it is mounted on the spring hole.

As an example of the elastic member of the present embodiment, a spring including, but not limited to, a cylindrical coil spring, a torsion spring, a leaf spring, and the like is used.

As an example of the elastic member of the present embodiment, an elastic pad including, but not limited to, a rubber pad, a polyurethane pad, etc. is used.

According to an example of the present disclosure, the connection terminal 14 is provided on the lower mounting portion 10-3 of the connection member 10 or the connection terminal 14 is provided on the movable block 11.

According to the example of the present disclosure, the lower mounting portion 10-3 of the connector 10 is fixed to the guide bar 2 by bolts or by welding, and the guide bar 2 serves as a lower support of the rail.
