It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a kind, not limited to the number of objects, for example, the first object can be one or more.

[0028] The embodiment of the present application discloses a clamping jaw device for soft bag conveying of overturning chain. Figures 1 to 2 The clamping jaw device for soft bag conveying of overturning chain provided by the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0029] Please refer to Figure 1 and Figure 2 The embodiment of the present application discloses a clamping jaw device for soft bag conveying of overturning chain, the disclosed clamping jaw device for soft bag conveying of overturning chain comprises a base 100, a guide rod 200, a guide wheel 300, a clamping arm 400 and an elastic member 500, wherein the base 100 is the basic component of the clamping jaw device, which can provide the installation basis for the guide rod 200, the guide wheel 300, the clamping arm 400 and the elastic member 500. Specifically, the guide rod 200 is movably arranged in the base 100, and exemplarily, please refer to Figure 1 The base 100 is provided with a through hole penetrating the base 100, and the guide rod 200 is arranged in the through hole. The guide wheel 300 is rotationally connected to the first end of the guide rod 200, and the two clamping arms 400 are hingedly connected to the second end of the guide rod 200, and the two clamping arms 400 are oppositely arranged, and exemplarily, in Figure 1 The first end can be the upper end of the guide rod 200, and the second end can be the lower end of the guide rod 200.

[0030] In the embodiment of the present application, the two clamping arms 400 have a clamping state and an open state. Specifically, the elastic member 500 is connected between the base 100 and the guide rod 200. For example, the elastic member 500 can be a compression spring. When the elastic member 500 is in a compressed state, the elastic member 500 can apply an elastic force to the guide rod 200 with the base 100 as a fulcrum, so that the guide rod 200 is pushed up to the first end, and the two clamping arms 400 are close to each other to be in the clamping state. At this time, the two clamping arms 400 can clamp the bag shoulder of the medical soft bag. When the guide wheel 300 is pressed, the guide rod 200 moves to the second end, and at the same time, the two second clamping arms 400 at the second end can be outwardly spread with the base 100 as a fulcrum, that is, the two clamping arms 400 are switched from the clamping state to the open state. For example, when the clamping jaw device moves to the position corresponding to the flat cam of the guide wheel 300 along the turnover chain, the guide wheel 300 slides on the flat cam and further compresses the elastic member 500, so that the two clamping arms 400 are outwardly spread with the base 100 as a fulcrum.

[0031] In the embodiment of the present application, one of the two clamping arms 400 is provided with a first magnetic member 430, and the other is provided with a second magnetic member 440. The first magnetic member 430 and the second magnetic member 440 are oppositely arranged and magnetically attracted to each other.

[0032] Based on the above technical solution, based on the elastic force of the elastic member 500, the two clamping arms 400 can clamp the bag shoulder of the medical soft bag, and the first magnetic member 430 and the second magnetic member 440 are magnetically attracted to each other, thereby providing an additional stable force, which can make the two clamping arms 400 more stable when clamping the bag shoulder, and help to prevent the medical soft bag from slipping or falling off during clamping. Compared with the traditional way of clamping the neck position of the medical soft bag by the clamp, the way of clamping the bag shoulder in the embodiment of the present application can increase the versatility of the clamp and reduce the workload of replacing the clamp.

[0033] At the same time, based on the strengthening effect of the first magnetic member 430 and the second magnetic member 440 on the clamping stability, the clamping jaw device of the present application can select an elastic member 500 with appropriate elasticity. In this way, the two clamping arms 400 in the open state can have a larger opening, thereby avoiding the shielding of the neck of the medical soft bag by the clamping arms 400, and thereby facilitating the visual detection of the appearance and damage of the neck, and thereby discovering potential safety hazards. It should be noted that the appropriate elasticity of the elastic member 500 in the embodiment of the present application means that the elastic force of the elastic member 500 should not be too large. If the elastic force of the elastic member 500 is too large, the two clamping arms 400 will be difficult to fully open by the pushing of the guide rod 200, and the two clamping arms 400 that are not fully open will interfere with the detection of the neck.

[0034] In the embodiment of the present application, the clamping arm 400 comprises a connecting rod 410 and a clamping arm body 420, wherein the clamping arm body 420 is rotationally connected to the base 100, and the clamping arm body 420 and the base 100 are rotationally connected through a first hinge shaft 610. One end of the connecting rod 410 is hingedly connected to the second end of the guide rod 200, and the other end of the connecting rod 410 is hingedly connected to the clamping arm body 420. When the guide wheel 300 is pressed to generate a pushing force on the guide rod 200 towards the second end, the guide rod 200 can push the clamping arm body 420 to rotate relative to the base 100 through the connecting rod 410, so that the two clamping arm bodies 420 are opened away from each other to switch to the open state. The first magnetic member 430 and the second magnetic member 440 are arranged on the clamping arm body 420.

[0035] In a further technical solution, the connecting rod 410 can be in an arc shape, which can avoid the first hinge shaft 610 when the guide rod 200 moves towards the second end and pushes the clamping arm body 420 to rotate relative to the base 100, thereby ensuring the smoothness and stability of the switching between the open state and the clamping state of the two clamping arms 400.

[0036] In the embodiment of the present application, please continue to refer to Figure 1 , the clamping arm body 420 comprises a first plate body 421 and a second plate body 422, wherein the two first plate bodies 421 are arranged in parallel and opposite to each other, and the second plate body 422 is connected between the two first plate bodies 421, and the extension direction of the first plate body 421 is perpendicular to the extension direction of the second plate body 422, so that the entire clamping arm body 420 is in an H shape, and the first magnetic member 430 or the second magnetic member 440 is arranged on the first plate body 421. For example, the first plate body 421 is provided with an embedding groove, and the first magnetic member 430 or the second magnetic member 440 can be embedded in the embedding groove and fixedly connected to the clamping arm body 420 by means of gluing. Of course, in other embodiments of the present application, the first magnetic member 430 or the second magnetic member 440 can also be fixedly connected to the clamping arm body 420 by means of a threaded connecting member, and the present application does not make specific limitations on this, as long as the first magnetic member 430, the second magnetic member 440 and the clamping arm body 420 can be connected and fixed.

[0037] As described above, in the embodiment of the present application, the clamping arm body 420 clamps the shoulder part of the medical soft bag to expose the neck part of the medical soft bag. It should be noted that the distance between the two first plate bodies 421 is greater than the radial dimension of the neck part of the medical soft bag. In this way, when the clamping arm body 420 clamps the medical soft bag, the two first plate bodies 421 are distributed on both sides of the neck part of the medical soft bag and avoid the neck part, so that the neck part of the medical soft bag can be exposed to realize normal visual inspection.

[0038] It should be noted that in the embodiment of the present application, the two first plate bodies 421 have oppositely arranged clamping surfaces, which are flat surfaces, and the opposite sides of the first magnetic member 430 and the second magnetic member 440 constitute part of the clamping surfaces. The flat clamping surfaces can more effectively disperse the pressure of the clamping arms 400 on the bag shoulder part, avoid the damage or leakage of the medical soft bag caused by too much pressure concentrated on one point, and also make the bag shoulder part bear force evenly and not prone to slipping.

[0039] In the embodiment of the present application, the clamping arm body 420 further comprises a second hinge shaft 620 connected between the two first plate bodies 421, and the end of the connecting rod 410 away from the guide rod 200 is rotatably sleeved on the second hinge shaft 620, that is, the connecting rod 410 can be connected at the middle position of the H-shaped clamping arm body 420 through the second hinge shaft 620, which can effectively balance the pressure of the clamping arm body 420 on both sides of the bag shoulder and prevent the clamping arm body 420 from deforming or damaging the medical soft bag due to uneven force.

[0040] In the embodiment of the present application, the guide rod 200 is provided with a limiting portion 210 at the first end thereof, and the elastic member 500 is sleeved on the guide rod 200 and located between the limiting portion 210 and the base 100, so that the limiting portion 210 can effectively prevent the elastic member 500 from being separated from the first end of the guide rod 200. It can be understood that when the two clamping arms 400 are in the clamping state, the two clamping arms 400 can be limitedly matched with the base 100 and prevent the guide rod 200 from sliding off the base 100 from the first end thereof.

[0041] In the embodiment of the present application, the clamping jaw device can further comprise a mounting plate 700, and the base 100 is fixedly connected with the turnover chain through the mounting plate 700. For example, the mounting plate 700 can have an L-shaped structure and be fixedly connected with the turnover chain through a threaded connecting member, and the base 100 can be connected with the mounting plate 700 through a third hinge shaft 630. In this way, when the entire clamping device moves to the turnover position, the base 100 can be adaptively turned over through the mounting plate 700.

[0042] In a further technical solution, the clamping jaw device can further comprise a roller 800 connected with the base 100 through a shaft 900, and the roller 800 is used to rollingly cooperate with the track outside the turnover chain. The roller 800 rollingly cooperates with the track, which can reduce the shaking of the clamping device on the turnover chain and improve the accuracy of the movement of the clamping device with the turnover chain.

[0043] It should be noted that the terms "comprising," "including," and any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element preceded by "comprises a... " does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus that comprises the recited element.
