Description

Technical Field

[0001] This utility model belongs to the technical field of ton bag unloading equipment, and in particular relates to a manual clamping device. Background Technology

[0002] Manual bag clamps are typically used to secure the openings of ton bags or bulk bags to equipment to assist in material unloading. Most existing manual bag clamps have a relatively simple structure, requiring operators to manually clamp and release them. However, in some cases, due to insufficient clamping strength, inadequate clamping force, or operational errors, the bag opening may not be effectively secured, leading to problems such as poor unloading or material spillage. This not only affects work efficiency but may also pose safety hazards.

[0003] In the prior art, some clamping devices, although employing complex mechanical designs, lack reliable interlocking functions, and the clamping mechanism is prone to incomplete locking or misoperation during operation. Utility Model Content

[0004] The purpose of this utility model is to provide a manual clamping device, which aims to solve the problem that some clamping devices, although they adopt complex mechanical designs, lack reliable interlocking functions, and the clamping mechanism is prone to incomplete locking or misoperation during operation.

[0005] This utility model is implemented as follows: a manual clamp, the manual clamp comprising:

[0006] A workbench, with a fixed bracket on one side, a guide mechanism on the fixed bracket, and a bag mouth clamping mechanism installed at one end of the guide mechanism;

[0007] An operating handle is connected to the fixed bracket via a movable connecting assembly. A multi-link mechanism is rotatably connected to the middle of the operating handle, and the multi-link mechanism is connected to the guide mechanism. The multi-link mechanism is used to drive the guide mechanism to move longitudinally by moving and rotating the operating handle.

[0008] As a further embodiment of this invention, the mobile connection component includes:

[0009] A groove rod is disposed at one end of the operating handle, and a limit guide post is connected to one end of the fixed bracket. The limit guide post is disposed in the groove of the groove rod and is used to limit the movement path of the operating handle.

[0010] As a further embodiment of this invention, the guiding mechanism includes:

[0011] A limiting sliding frame is mounted on the fixed bracket, and a lifting slide rod is slidably mounted inside the limiting sliding frame. The top end of the lifting slide rod is connected to the bag opening clamping mechanism.

[0012] As a further embodiment of this utility model, the multi-link mechanism includes:

[0013] The first link has one end rotatably connected to the middle of the operating handle, and the other end rotatably connected to the fixed bracket.

[0014] The second link has one end rotatably connected to the same position on the middle of the operating handle as the first link, and the other end of the second link is rotatably connected to a third link, one end of which is rotatably connected to the lifting slide bar.

[0015] As a further improvement of this utility model, a limiting device is also included, which is used to automatically lock the current state of the multi-link mechanism when the operating handle reaches the predetermined position.

[0016] As a further embodiment of this invention, the limiting device also includes a spring reset mechanism, which is used to automatically release the lock on the lifting slide rod when the operating handle is reset.

[0017] The manual clamp provided by this utility model has the following beneficial effects:

[0018] The interlocking design of the multi-link mechanism ensures that the bag opening will not be accidentally released after clamping, guaranteeing smooth material feeding and improving work efficiency.

[0019] The interlock function prevents operational errors or incomplete locking of the clamps, reducing the risk of material leakage or safety accidents during unloading.

[0020] Despite employing a multi-link mechanism, the design remains easy to operate, allowing users to clamp and lock the device simply through manual operation.

[0021] The design of this invention can be applied to ton bags or large bags of different specifications, and has high versatility and adaptability. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] like Figure 1 and Figure 2 As shown in this embodiment of the invention, the manual clamp includes:

[0028] Workbench 1, a fixed bracket 2 is provided on one side of the workbench 1, a guide mechanism is provided on the fixed bracket 2, and a bag mouth clamping mechanism 3 is installed at one end of the guide mechanism;

[0029] The operating handle 4 is connected to the fixed bracket 2 via a movable connecting assembly. A multi-link mechanism is rotatably connected to the middle of the operating handle 4, and the multi-link mechanism is connected to the guide mechanism. The multi-link mechanism is used to drive the guide mechanism to move longitudinally by moving and rotating the operating handle 4.

[0030] The bag opening clamping mechanism 3 includes a bag opening sealing mechanism, which is connected to a multi-link mechanism to enable the bag opening clamping mechanism 3 to move up and down to seal the bag opening.

[0031] The multi-link mechanism is interconnected by multiple links and an interlocking structure ensures that the clamping arm can be firmly locked in the predetermined position when the operating handle 4 is closed, ensuring that the bag opening is reliably clamped.

[0032] The multi-link mechanism uses an interlocking structure design. When the operating handle 4 reaches the predetermined position, the mechanism automatically locks to prevent the clamp from loosening and ensure that the clamping arm will not accidentally detach during operation, thus ensuring the safe unloading of materials.

[0033] In this embodiment of the utility model, the mobile connection component includes:

[0034] A groove rod 5 is disposed at one end of the operating handle 4, and a limiting guide post 6 is connected to one end of the fixed bracket 2. The limiting guide post 6 is disposed in the groove of the groove rod 5 and is used to limit the movement path of the operating handle 4.

[0035] In this embodiment of the utility model, the guiding mechanism includes:

[0036] A limiting sliding frame 7 is mounted on the fixed bracket 2. A lifting slide rod 8 is slidably mounted inside the limiting sliding frame 7. The top end of the lifting slide rod 8 is connected to the bag opening clamping mechanism 3.

[0037] In this embodiment of the utility model, the multi-link mechanism includes:

[0038] The first link 9 has one end rotatably connected to the middle of the operating handle 4 and the other end rotatably connected to the fixed bracket 2.

[0039] The second link 10 has one end rotatably connected to the same position on the middle of the operating handle 4 as the first link 9, and the other end of the second link 10 is rotatably connected to the third link 11, one end of which is rotatably connected to the lifting slide bar 8.

[0040] As a further improvement of this utility model, a limiting device is also included, which is used to automatically lock the current state of the multi-link mechanism when the operating handle 4 reaches the predetermined position.

[0041] The interlocking function of this structure is achieved through a combination of a multi-link mechanism and a limiting device. When the operator pulls the handle, the multi-link mechanism begins to move, and the clamping arm gradually tightens until it reaches the predetermined locking point. At this point, the limiting device automatically engages in the locking groove to prevent the clamping arm from loosening. The limiting device will only release the lock when the handle is operated again, allowing the clamp to open smoothly.

[0042] As a further embodiment of this utility model, the limiting device also includes a spring reset mechanism, which is used to automatically release the lock on the lifting slide bar 8 when the operating handle 4 is reset.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
