Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, specifically a fixture error prevention device. Background Technology

[0002] As the core carrier of intelligent retail equipment, the quick clamping and release function of the shelves in automatic weighing vending machines directly affects the stability of equipment operation and maintenance efficiency. The existing automatic weighing vending machines generally use traditional quick clamping fixture structures for the quick clamping and release of shelves.

[0003] When using quick clamps, the shelf is released by lifting the pressure rod and pressed down by pressing the pressure rod. However, the quick clamps lack a physical foolproof mechanism. If the shelf is not locked in time after assembly or maintenance, the shelf is in a movable state. Vibration during equipment movement or operation can easily cause the shelf to collide with the cabinet, resulting in deformation or damage to the shelf. Utility Model Content

[0004] The present invention aims to provide a clamping anti-foolproof device, which can provide a physical anti-foolproof mechanism to ensure that the corresponding shelf of the automatic weighing vending machine is locked under normal use.

[0005] This utility model discloses a clamp anti-fooling device, which is applied to a cabinet with clamps and cabinet doors. It includes: a lifting link, one end of which is connected to the clamp's pressure rod, and the other end of which is connected to an anti-fooling rod. The anti-fooling rod moves to switch the clamp to a locked or unlocked state. The anti-fooling rod can move in a direction close to or away from the cabinet door. The stroke range of the anti-fooling rod has a first position and a second position. The first position corresponds to the clamp's locked state, and the second position corresponds to the clamp's unlocked state.

[0006] The end of the anti-fool lever in the first position is away from the opening and closing range of the cabinet door, so as not to hinder the opening and closing of the cabinet door; the end of the anti-fool lever in the second position is within the opening and closing range of the cabinet door, thus hindering the opening and closing of the cabinet door.

[0007] According to the above technical solution, by adding a lifting link at the pressure bar position of the clamp, while retaining the ability of the quick clamp to perform efficient clamping and releasing, a foolproof constraint is provided to prevent the cabinet door from closing if the shelf is not locked. This can effectively ensure that the cabinet door can be closed normally only when the clamp is locked, and prevent the shelf that is not clamped from hitting the cabinet body after the cabinet door is closed.

[0008] Optionally, the anti-fouling rod is installed near the opening edge of the cabinet.

[0009] According to the above technical solution, when the clamp is in the unlocked state, the end of the anti-fooling rod will extend out of the opening edge, providing a closing block in the initial stage of cabinet door closing, making it easier for the operator to notice and further improving the anti-fooling effect.

[0010] Optionally, the cabinet also includes a mounting base, in which the lifting linkage is rotatably mounted.

[0011] According to the above technical solution, the hinge point of the mounting base can form a stable rotation fulcrum, ensuring the smooth movement of the lifting linkage, thereby driving the clamp to quickly and stably switch between the locked and unlocked states.

[0012] Optionally, the lifting link is a bent rod with a bend that is hinged to the mounting base.

[0013] According to the above technical solution, stress concentration near the hinge point can be effectively dispersed, thus extending the service life.

[0014] Optionally, one end of the lifting linkage is positioned toward the clamp's pressure bar, and the other end is positioned toward the cabinet opening.

[0015] Optionally, a groove is provided at the end where the lifting link connects to the pressure rod.

[0016] Optionally, the pressure rod is provided with a sliding rod corresponding to the sliding groove, and the sliding rod is slidably disposed in the sliding groove.

[0017] Optionally, the slide has a first end and a second end. When the slide bar is at the first end, the clamp is in a locked state, and when the slide bar is at the second end, the clamp is in an unlocked state.

[0018] According to the above technical solution, through the cooperation of the slide groove and the slide rod, when the anti-fool rod is lifted or pressed down, the movement of the pressure head can be controlled, thereby enabling the fixture to switch quickly and stably between the locked and unlocked states.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Figure 1 This is a schematic diagram of the clamp anti-foolproof device in the clamp unlocked state according to an embodiment of the present invention; Figure 2 This is a schematic diagram of the clamp anti-foolproof device in the clamp locking state in an embodiment of this utility model.

[0024] like Figure 1 and Figure 2 As shown, a clamp anti-fool device 100 of this embodiment is applied to a cabinet 30 equipped with a clamp 10 and a cabinet door 20. It includes a lifting link 101, one end of which is connected to the pressure rod 11 of the clamp 10, and the other end is connected to an anti-fool rod 102. The anti-fool rod 102 is activated to drive the clamp 10 to switch to a locked or unlocked state.

[0025] Specifically, in this embodiment, the clamp 10 is a horizontal quick clamp, and the shelf 40 is movably disposed in the track 50. The clamp 10 can quickly clamp the shelf 40 in the horizontal direction. When the pressure rod 11 is lifted, it drives the pressure head 12 to lift, releasing the shelf 40; when the pressure rod 11 is pressed down, it drives the pressure head 12 to press down, clamping the shelf 40. When the above-mentioned clamp 10 is in use, due to the lack of a foolproof mechanism, when the pressure rod 11 is lifted, that is, when the shelf 40 is not pressed and locked, the cabinet door 20 can still close normally. At this time, the movable shelf 40 is prone to collision with the cabinet body 30, resulting in deformation or damage to the shelf 40.

[0026] In this embodiment, in order to provide physical anti-foolproof constraints, a lifting link 101 is added to the pressure bar 11 of the clamp 10. One end of the lifting link 101 is set toward the pressure bar 11 of the clamp 10 and connected to the pressure bar 11, and the other end is set toward the opening of the cabinet 30 and connected to the anti-foolproof bar 102.

[0027] The anti-fool lever 102 can move in a direction close to or away from the cabinet door 20. The travel range of the anti-fool lever 102 has a first position and a second position. The first position corresponds to the locked state of the clamp 10, and the second position corresponds to the unlocked state of the clamp 10.

[0028] refer to Figure 1 The end of the anti-fooling rod 102, located in the second position, is within the opening and closing range of the cabinet door 20, thus hindering the opening and closing of the cabinet door 20; Reference Figure 2The end of the anti-fooling rod 102 in the first position is away from the opening and closing stroke range of the cabinet door 20, so as not to hinder the opening and closing of the cabinet door 20.

[0029] In this embodiment, by adding a lifting link 101 at the pressure bar 11 position of the clamp 10, while retaining the ability of the quick clamp 10 to perform efficient clamping and releasing, a foolproof constraint is provided in a simple structure so that the cabinet door 20 cannot be closed if the shelf 40 is not locked. This can effectively ensure that the cabinet door 20 can only be closed normally when the clamp 10 is locked, and prevent the shelf 40 that is not clamped from hitting the cabinet body 30 after the cabinet door 20 is closed.

[0030] Furthermore, although this embodiment uses a horizontal quick-release clamp 10 as an example, this application is not limited to this. This application does not limit the specific structure of the clamp 10 that can be provided with anti-foolproof constraints using the clamp anti-foolproof device 100. As long as the clamp 10 can be locked or unlocked by connecting it to the lifting link 101, and the end of the anti-foolproof rod 102 is located within the opening and closing stroke range of the cabinet door 20 when the clamp 10 is in the unlocked state, thus hindering the opening and closing of the cabinet door 20, it should fall within the protection scope of this application.

[0031] Furthermore, the cabinet 30 is also provided with a mounting base 103, and the lifting rod 101 is rotatably mounted in the mounting base 103.

[0032] Specifically, the lifting link 101 is hinged in the mounting base 103, which can form a stable rotation fulcrum, thereby efficiently and stably converting the lifting or pressing action of the anti-fooling rod 102 into the rotational motion of the lifting link 101, thus ensuring the smooth movement of the lifting link 101 and driving the clamp 10 to quickly and stably switch between the locked and unlocked states.

[0033] The lifting link 101 is a bent rod with a bent portion, which is hinged to the mounting base 103.

[0034] refer to Figure 1 and Figure 2 In this embodiment, the bent portion of the lifting link 101 is designed with an obtuse-angled arc transition, which can effectively disperse stress concentration near the hinge point and extend service life.

[0035] Furthermore, in this embodiment, the mounting base 103 and the clamp 10 are jointly mounted on the upper surface of the track 50 and located on the inner side of the cabinet 30, which avoids occupying the internal space of the cabinet 30 and thus effectively avoids the risk of interference of the clamp error prevention device 100 to other components.

[0036] The anti-fouling rod 102 is installed near the opening edge of the cabinet 30.

[0037] refer to Figure 1 By setting the anti-foolproof lever 102 at the edge of the opening adjacent to the cabinet 30, when the clamp 10 is in the unlocked state, the end of the anti-foolproof lever 102 will extend out of the edge of the opening of the cabinet 30, and can close and block the cabinet door 20 at the initial stage of closing, making it easier for the operator to notice and further improving the anti-foolproof effect.

[0038] refer to Figure 1 and Figure 2 The lifting link 101 is connected to the pressure rod 11 at one end and is also provided with a sliding groove 1011. The pressure rod 11 is matched with a sliding rod 111 corresponding to the sliding groove 1011. The sliding rod 111 is slidably disposed in the sliding groove 1011.

[0039] The slide 1011 has a first end and a second end. When the slide bar 111 is at the first end, the clamp 10 is in a locked state. When the slide bar 111 is at the second end, the clamp 10 is in an unlocked state.

[0040] Specifically, when the anti-fool lever 102 is lifted, the slide groove 1011 moves downward and drives the slide rod 111 to move towards the first end, thereby driving the pressure rod 11 to press down, which in turn drives the pressure head 12 to press the shelf 40, so that the clamp 10 switches to the locked state; when the anti-fool lever 102 is pressed down, the slide groove 1011 moves upward and drives the slide rod 111 to move towards the second end, thereby driving the pressure rod 11 to lift up, which in turn drives the pressure head 12 to release, so that the clamp 10 switches to the unlocked state.

[0041] In this embodiment, through the cooperation of the slide groove 1011 and the slide rod 111, when the anti-fool rod 102 is lifted or pressed down, the bent lifting link 101 rotates around the mounting hinge point, the slide groove 1011 moves accordingly, and pushes the slide rod 111 to slide along the trajectory in the slide groove 1011, thereby driving the pressure rod 11 to move and correspondingly driving the pressure head 12 to complete the clamping or releasing action. The guide provided by the slide groove 1011 ensures the continuity of the action. Thus, by controlling the movement of the anti-fool rod 102, the movement of the pressure head 12 can be quickly and stably controlled, so that the clamp 10 can quickly and stably switch between the locked state and the unlocked state.

[0042] The above are merely preferred embodiments of the present utility model and are 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.
