Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a pressure restraint device. Background Technology

[0002] In the field of battery manufacturing technology, pressure restraint equipment is a common process device. During the process, the movable pressure applying mechanism of the pressure restraint equipment can hold multiple batteries and apply pressure to them to compress or test them. During maintenance, this equipment typically uses a fixed structure installed between the movable pressure applying mechanism and the fixed base to prevent accidental movement of the movable pressure applying mechanism from pinching and injuring workers. However, existing fixed structures are inconvenient to install and disassemble, and workers are not protected during installation; if the movable pressure applying mechanism moves accidentally at this time, it can still cause pinching injuries. Furthermore, the removed fixed structure is easily lost. Utility Model Content

[0003] The purpose of this utility model is to provide a pressure restraint device, which is equipped with an adjustable scapegoat mechanism. The scapegoat mechanism can effectively restrict the movement of the active pressure-applying mechanism, reduce the probability of injury to maintenance personnel, and the scapegoat mechanism is not easily lost.

[0004] To achieve this objective, one aspect of this utility model adopts the following technical solution:

[0005] A pressure restraint device includes: a fixed base and a movable pressure applying mechanism, the movable pressure applying mechanism being movable relative to the fixed base to apply pressure toward a member to be pressed; a scapegoat mechanism, the scapegoat mechanism including a fixed member and a movable member, the fixed member being connected to the fixed base, the movable member being movable relative to the fixed member, the scapegoat mechanism having a first operating state and a second operating state, in the first operating state, the movable member disengaging from the movable pressure applying mechanism to allow the movable pressure applying mechanism to move relative to the fixed base, and in the second operating state, the movable member abutting against or connecting to the movable pressure applying mechanism to restrict the movable pressure applying mechanism.

[0006] The beneficial effects of this utility model are as follows: Because the pressure restraint device has a scapegoat mechanism on the fixed base, the scapegoat mechanism includes a fixed component fixed relative to the fixed base and a movable component movable relative to the fixed component. The movable component has a first working state of disengaging from the movable pressure mechanism and a second working state of abutting or connecting to the movable pressure mechanism to restrict it. During equipment maintenance, maintenance personnel only need to operate the movable component to switch the working state of the scapegoat mechanism. This ensures the safety of maintenance personnel and reduces the probability of them being accidentally pinched by the movable pressure mechanism. Furthermore, when the pressure restraint device is working normally, the movable component can be adjusted to the first working state without removing the entire scapegoat mechanism from the fixed base, thus avoiding the loss of parts.

[0007] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0016] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0018] This utility model discloses a pressure restraint device, with reference to... Figure 1 As shown, the pressure restraint device includes a fixed base 100, a movable pressure applying mechanism 200, and a scapegoat mechanism 300. The movable pressure applying mechanism 200 is movable relative to the fixed base 100 to apply pressure toward the object to be pressed. The scapegoat mechanism 300 includes a fixed member 310 and a movable member 320. The fixed member 310 is connected to the fixed base 100, and the movable member 320 is movable relative to the fixed member 310. The scapegoat mechanism 300 has a first working state and a second working state. In the first working state, the movable member 320 is disengaged from the movable pressure applying mechanism 200, allowing the movable pressure applying mechanism 200 to move relative to the fixed base 100. In the second working state, the movable member 320 abuts against or connects to the movable pressure applying mechanism 200 to restrict the movable pressure applying mechanism 200.

[0019] Understandably, since the pressure restraint device has a scapegoat mechanism 300 on the fixed base 100, the scapegoat mechanism 300 includes a fixed member 310 fixed relative to the fixed base 100 and a movable member 320 movable relative to the fixed member 310. The movable member 320 has a first working state that is disengaged from the movable pressure applying mechanism 200 and a second working state that abuts against or connects to the movable pressure applying mechanism 200 to restrict the movable pressure applying mechanism 200. During equipment maintenance, maintenance personnel only need to operate the movable member 320 to switch the working state of the scapegoat mechanism 300. On the one hand, this can ensure the safety of maintenance personnel and reduce the probability of maintenance personnel being accidentally pinched by the movable pressure applying mechanism 200. On the other hand, since the movable member 320 can be adjusted to the first working state when the pressure restraint device is working normally, it is not necessary to remove the entire scapegoat mechanism 300 from the fixed base 100, thus avoiding the loss of parts.

[0020] refer to Figures 2-3 As shown, one end of the fixed member 310 is connected to the fixed base 100, and the movable member 320 is slidably mounted on the fixed base 100. In the first working state, the vertical projection of the movable member 320 is offset from the vertical projection of the movable pressure mechanism 200. In the second working state, the movable member 320 can abut against the movable pressure mechanism 200 to restrict the movable pressure mechanism 200. It can be understood that since the movable member 320 is slidably mounted on the fixed base 100, in actual operation, it is only necessary to push the movable member 320 relative to the fixed member 310 to switch the movable member 320 between the first and second working states, which is very convenient. Furthermore, because the projection of the movable part 320 in the vertical direction is offset from the projection of the movable pressure mechanism 200 in the vertical direction in the first working state, it ensures that the movable part 320 will not interfere with the normal movement of the movable pressure mechanism 200 when the pressure restraint device is working normally, thus ensuring the normal operation of the process. In the second working state, the movable part 320 can stop against the movable pressure mechanism 200 to restrict it. During equipment maintenance, if the movable pressure mechanism 200 moves unexpectedly, the movable part 320 can stop against it, thus playing a good limiting role and reducing the probability of the movable pressure mechanism 200 injuring maintenance personnel.

[0021] It should be noted that in this embodiment, one end of the fixing member 310 is fixed to the fixing base 100 by a screw. In other embodiments of this utility model, the fixing member 310 may also be directly welded to the fixing base 100, or connected to the fixing base 100 by a snap-fit ​​connection or other connection methods, and is not limited to the screw connection method of this embodiment.

[0022] Optional, see reference Figures 2-3 As shown, the other end of the fixing member 310 is provided with a through mounting hole 311. The fixing member 310 is also provided with a positioning hole 312 communicating with the mounting hole 311. The movable member 320 is movably installed in the mounting hole 311. The scapegoat mechanism 300 includes a positioning member 330, which is installed in the positioning hole 312 to position the movable member 320. It can be understood that in actual operation, the movable member 320 is slidably installed in the mounting hole 311 and positioned by the positioning member 330. In actual adjustment, when the movable member 320 needs to be adjusted, the positioning member 330 is first operated to disengage it from the movable member 320, thereby releasing the movable member 320. Then, the position of the movable member 320 is adjusted. After the adjustment is completed, the movable member 320 is locked by the positioning member 330. This ensures that the moving part 320 remains stably in the first or second working state, reducing the likelihood of the scapegoat mechanism 300 failing to protect itself due to the shaking of the moving part 320 or the scapegoat mechanism 300 affecting the normal movement of the moving pressure mechanism 200.

[0023] Optionally, the movable component 320 is provided with a first adjustment hole 321 and a second adjustment hole 322. In the first working state, the first adjustment hole 321 corresponds to the positioning hole 312, and the positioning component 330 passes through both the first adjustment hole 321 and the positioning hole 312. In the second working state, the second adjustment hole 322 corresponds to the positioning hole 312, and the positioning component 330 passes through both the second adjustment hole 322 and the positioning hole 312. It is understood that in the first working state, the movable component 320 is positioned by the positioning component 330 passing through the first adjustment hole 321, and in the second working state, the movable component 320 is positioned by the positioning component 330 passing through the second adjustment hole 322. This ensures that the movable component 320 is stably maintained in either the first or second working state, thereby further reducing the probability of the scapegoat mechanism 300 failing due to the swaying of the movable component 320, or the scapegoat mechanism 300 affecting the normal movement of the movable pressure mechanism 200.

[0024] In this embodiment, the positioning element 330 is a pin, and the first adjustment hole 321 and the second adjustment hole 322 are both smooth holes. Of course, in other embodiments of this utility model, the positioning element 330 can also be a bolt, and the first adjustment hole 321 and the second adjustment hole 322 are both threaded holes.

[0025] Alternatively, the first adjustment holes 321 of the multiple movable parts 320 are correspondingly provided, and the second adjustment holes 322 of the multiple movable parts 320 are correspondingly provided, so that the multiple movable parts 320 share a single positioning element 330. It is understood that having multiple movable parts 320 share a single positioning element 330 for positioning simplifies the locking and positioning operations of the movable parts 320, making it easier for staff to adjust the movable parts 320.

[0026] Optionally, there are multiple mounting holes 311 and multiple movable parts 320, with each movable part 320 mounted in one mounting hole 311. It is understood that by using multiple movable parts 320 to limit the movement of the movable pressure mechanism 200, the limiting effect on the movable pressure mechanism 200 can be enhanced, reducing the likelihood of the movable pressure mechanism 200 injuring maintenance personnel. In this embodiment, there are two movable parts 320. Of course, in other embodiments of this invention, three, four, or even more movable parts 320 can be selected according to actual needs.

[0027] Optionally, the scapegoat mechanism 300 further includes a connecting seat 340, which is connected to multiple movable parts 320 to enable synchronous adjustment of the multiple movable parts 320. It is understood that the added connecting seat 340 connects the multiple movable parts 320 together, facilitating adjustment by the operator. It should be noted that in this embodiment, the connecting seat 340 and the movable parts 320 are connected by screws. However, in other embodiments of this invention, the connecting seat 340 and the movable parts 320 can also be connected by welding, or the connecting seat 340 and the movable parts 320 can be integrally formed.

[0028] It should be noted that in other embodiments of this utility model, the first adjustment hole 321 and the second adjustment hole 322 may not be provided on the movable part 320, the positioning hole 312 is set as a threaded hole, and the positioning part 330 is a bolt. During the adjustment process, the bolt can be rotated to stop it against the movable part 320, which can also play the role of positioning the movable part 320.

[0029] refer to Figures 2-3 As shown, the scapegoat mechanism 300 also includes a detection element 350, which is installed at the other end of the fixed element 310 and can detect the position of the movable element 320. It is understood that by adding the detection element 350, the position of the movable element 320 can be detected, and the position status of the movable element 320 can be observed on the control panel after the pressure restraint equipment is turned on. This prevents the operator from forgetting to adjust the movable element 320 after maintenance, thus avoiding the phenomenon of the movable pressure applying mechanism 200 hitting the movable element 320 during the process.

[0030] Optionally, the detection element 350 includes two spaced-apart photoelectric switches, and the scapegoat mechanism 300 also includes a detection plate 360. One end of the detection plate 360 ​​is connected to the movable element 320, and the other end can be detected by the photoelectric switch. Detection by the photoelectric switch facilitates the detection of the movable element 320. Further optionally, the detection plate 360 ​​is an L-shaped plate 361. One end of the L-shaped plate 361 is connected to the connecting seat 340 of the movable element 320, and the other end has bent edges 362 on opposite sides. The bent edges 362 can move between the transmitting and receiving ends of the photoelectric switch, thereby triggering the photoelectric switch.

[0031] In an alternative embodiment of this utility model, reference is made to... Figures 4-5 As shown, the fixed component 310 includes a hook, and the movable component 320 includes a limiting chain. The hook is connected to the movable pressure mechanism 200, and one end of the limiting chain is fixedly connected to the fixed base 100, while the other end can engage with the hook. In the first working state, the other end of the limiting chain is detached from the hook; in the second working state, the other end of the limiting chain is attached to the hook. It is understood that because the movable component 320 includes a limiting chain, in actual operation, simply engaging or disengaging the limiting chain from the hook allows the movable component 320 to switch between the first and second working states, making operation very convenient.

[0032] It should be noted that in actual equipment, the scapegoat mechanism 300 of the pressure restraint device can be one, and it is... Figures 2-3 The structure shown can also be Figures 4-5 In an alternative embodiment, the pressure restraint device has two scapegoat mechanisms 300, one of which is... Figures 2-3 The structure shown is another one. Figures 4-5 The structure of the scapegoat mechanism 300 can be selected based on the type of actual pressure restraint device.
