Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

The present embodiment provides a clamp 100, please refer to fig. 1, fig. 2 and fig. 3, which includes a clamp body 1, a clamping arm 2 and an elastic element 32.

The holder body 1 has a holding wall 11.

Referring to fig. 5, 6 and 7, the clamping arm 2 is connected to the clamp body 1 and can rotate relative to the clamping wall 11, and a clamping space 2a for clamping the side rail is formed between the clamping wall 11 and the clamping arm 2. The holder 100 has a holding port 2b for entering the side rail, and the side rail enters and exits the holding space 2a from the holding port 2 b.

The elastic element 32 exerts a drive torque on the clamping arm 2 towards the clamping wall 11. That is, the elastic element 32 always applies a preload to the clamping arm 2. For example, fig. 5 shows an initial state in which the clamping arm 2 is not clamped into the side rail and no external force is applied to the clamp 100, and the pre-tightening force of the elastic element 32 on the clamping arm 2 can keep the clamping arm 2 in the initial state and will not shake freely.

A grip portion 22 exposed to the holder body 1 is connected to the arm 2, and the grip between the grip wall 11 and the arm 2 can be released by pressing the grip portion 22.

When needs fasten holder 100 on the side rail, external force promotes arm lock 2 or the portion 22 of gripping, make to the direction of keeping away from clamping wall 11 rotate, go into clamping space 2a from centre gripping mouth 2b card when the side rail, external force release arm lock 2, arm lock 2 resets under elastic component 32's effect, make arm lock 2 card on the side rail, so, keep arm lock 2 the state of card on the side rail all the time through elastic component 32, realize the preliminary location of holder 100 on the side rail at least, the shake volume is little behind the side rail in holder 100 joint.

Thereafter, if the holder 100 needs to be taken off from the side rail, the holding portion 22 is pressed forcibly, the holding portion 22 drives the clamping arm 2 to move in a direction away from the holding wall 11, the clamping arm 2 releases the side rail, the side rail is taken out from the holding opening 2b, and then the holding portion 22 is released, so that quick unlocking is achieved.

It should be noted that when the clamping arm 2 rotates to the limit position in the direction away from the clamping wall 11, the clamping opening 2b has enough space to ensure that the clamp 100 can be smoothly hooked to the side rail.

Illustratively, the gripper body 1 is provided with a stopper portion, and when the grip portion 22 is pressed to a limit position, for example, the position of the grip portion 22 shown in fig. 6 is the pressed limit position, the grip portion 22 abuts against the stopper portion. The stopper can prevent the grip 22 from being pressed excessively, and prevent the grip 22 from being damaged or destroyed due to an over-stroke.

The specific structure of the limiting part is not limited, and for example, the limiting part may be a rib, a protrusion, or any other structure.

Illustratively, referring to fig. 3, 5 and 6, the holder body 1 has a holding cavity 1a, at least one side of the holding cavity 1a is opened, and a side rail enters and exits the holding space 2a from the opened portion. The clamping arms 2 are accommodated in the clamping cavity 1a, that is, the clamping arms 2 are hardly visible to the user from the outside of the clamp 100, on one hand, objects in the environment are prevented from affecting the movement of the clamping arms 2, and on the other hand, the appearance of the clamp body 1 is more neat and beautiful, and the disinfection is also facilitated.

Illustratively, referring to fig. 2, 3, 5, 6 and 7, the sidewall of the clamping cavity 1a is provided with an avoiding gap 1b, and the grip portion 22 protrudes to the outside of the clamp body 1 through the avoiding gap 1 b. One end of the holding part 22 connected with the clamping arm 2 is located in the clamping cavity 1a, and the other end of the holding part 22 extends out of the avoiding notch 1b to the outside of the clamping cavity 1a for being held and applied with force by a user. The escape notch 1b is used to escape the movement stroke of the grip portion 22. In this way, the grip 22 can be easily gripped by the user without significantly increasing the external dimensions of the holder body 1.

Illustratively, the grip portion 22 is fixedly connected to the clamp arm 2, and the grip portion and the clamp arm move synchronously.

The specific manner of fixedly connecting the holding portion 22 and the clamping arm 2 is not limited, for example, in some embodiments, screwing, welding, riveting, snapping, etc. are used. In other embodiments, the clamping arm 2 and the holding portion 22 are a unitary structure, such as an injection molded piece, or a unitary metal piece.

The specific configuration of the grip portion 22 is not limited as long as it can be easily gripped by a user and easily applied with force. For example, the grip portion 22 has a long rod shape.

Illustratively, the grip portion 22 is a plate-like structure, and referring to fig. 6, when the grip portion 22 is pressed to the limit position, the plate-like structure abuts against the outer surface of the holder body 1. In this embodiment, the holding portion 22 and the clamping arm 2 form an acute angle, so that the holding portion 22 is closer to the outer surface of the holder body 1, the length of the holding portion 22 in the direction away from the holder body 1 is prevented from being too long, the structure of the holder 100 can be more compact, and in addition, the holding portion 22 only needs a small rotating space, and the probability of interference with other structures around the side rail is reduced.

In this embodiment, the outer surface of the holder body 1 serves as a limiting portion for limiting the holding portion 22, and thus, no additional structure is required to limit the holding portion 22.

The escape recess 1b is disposed, for example, on a side wall of the clamping chamber 1a remote from the clamping wall 11. Namely, the relief notch 1b and the holding wall 11 are located on two opposite side walls of the holding chamber 1 a. The portion of gripping 22 is connected in the one side that arm lock 2 deviates from centre gripping space 2a, and the user can better produce great moment to arm lock 2 to the portion of gripping 22 application of force, the user application of force of being more convenient for.

Illustratively, in some embodiments, the peripheral edge of the avoidance gap 1b is closed, and the movement travel range of the grip portion 22 is within the area defined by the avoidance gap 1 b. When the peripheral surrounding edge of the avoiding notch 1b is arranged in a closed manner, one edge of the avoiding notch 1b forms a limiting part.

In other embodiments, at least one of the circumferential surrounding edges of the avoiding notch 1b is open, for example, the surrounding edge of the side close to the side where the side rail enters and exits is open in the circumferential surrounding edge of the avoiding notch 1b, so that the avoiding notch 1b can keep a smaller size in the range of the movement stroke of the holding portion 22, for example, after the elastic member 32 drives the clamping arm 2 to move towards the direction of the clamping wall 11, the holding portion 22 can be close to the open position of the avoiding notch 1b, and the holding portion 22 does not need to be limited in the direction.

For example, referring to fig. 6, when the grip portion 22 is pressed, a portion of the clip arm 2 extends into the avoidance gap 1b, for example, extends into the avoidance gap 1b from an opening of the avoidance gap 1 b. In this way, under the condition of satisfying the movement stroke of the clamp arm 2, the size of the clamp chamber 1a can be reduced, so that the structure of the clamp 100 is more compact.

Referring to fig. 3, 5, 6, 8 and 9, a baffle 21 is connected to the clamping arm 2, and the baffle 21 extends from a portion of the clamping wall 11 or a portion adjacent to the portion to which the clamping wall 11 is rotatably connected in a direction approaching the clamping wall 11. When the user looks inwards from the open position of the clamping cavity 1a, the baffle plate 21 plays a role in blocking the sight, and the user cannot see parts and structures behind the baffle plate 21, so that the attractive effect is achieved.

For example, referring to fig. 2, fig. 5, fig. 6, fig. 8 and fig. 9, the clamping device 100 includes a first shaft 31, the clamping arm 2 is provided with a first shaft hole 2c, and the first shaft 31 is inserted into the first shaft hole 2c and is rotatably connected to the sidewall of the clamping cavity 1 a. Therefore, the clamping arm 2 can be rotatably arranged on the side wall of the clamping cavity 1a, and the installation mode is simple.

The specific type of the elastic member 32 is not limited, and may be, for example, a tension spring, a compression spring, a torsion spring, or the like, and may also be a rubber strip or the like.

In an embodiment, referring to fig. 3, the elastic member 32 is a torsion spring, the torsion spring is sleeved on the first shaft 31, the first shaft 31 provides an installation position for the torsion spring, and the torsion spring does not interfere with the stroke range of the clamping arm 2.

Of the opposite sides of the shutter 21, the side facing away from the chucking port 2b is the back side.

Referring to fig. 3, the clamper 100 includes a rotating member 7 disposed on the back side of the blocking plate 21 and a pull shaft 4, and referring to fig. 5, 6 and 8, the rotating member 7 is rotatably connected to the clamping arm 2, and one end of the pull shaft 4 is connected to the rotating member 7. When the side rail is installed in the holder 100, the pulling shaft 4 is pulled toward the side away from the side rail, and the clamping arms 2 rotate toward the direction of clamping the side rail.

In this embodiment, the pulling shaft 4 is pulled toward the side away from the side rail, and the pulling shaft 4 applies an acting force to the clamping arm 2 through the rotating member 7, and the acting force generates a driving torque to the clamping arm 2 to drive the clamping arm 2 to rotate toward the direction of clamping the side rail. It should be noted that the torque generated by the pulling shaft 4 to the clamping arm 2 is the same as the torque generated by the elastic member 32 to the clamping arm 2 in the same direction, and is the driving torque.

It can be understood that when the pulling shaft 4 is kept in the tensioned state, the clamping arms 2 lock the side rail in the clamping space 2a, so that the clamp 100 and the side rail are reliably and stably locked, and even if an external force touches the clamp 100 or the side rail, the clamping arms 2 are not loosened, and the clamp 100 is not separated from the side rail.

For example, referring to fig. 8 and 9, the clamping arm 2 is provided with a rotating position 20, referring to fig. 3 and 9, the rotating member 7 includes a second shaft 71 and a shaft 72 connected to the second shaft 71, the second shaft 71 is disposed through the rotating position 20, and the shaft 72 is connected to the second shaft 71 and extends away from the baffle 21.
