Description

Technical Field

[0001] This application relates to the field of auxiliary structure technology for container lids, and in particular to a multi-point linkage quick clamping mechanism. Background Technology

[0002] Most container processing equipment currently on the market consists of a container body and a cover. Taking a mixer as an example, the vacuum cover of a traditional mixer is connected to the transmission box with screws. In some working conditions where the vacuum cover needs to be disassembled frequently to clean the internal structure, the fasteners need to be disassembled and reassembled each time the cleaning is done. This is complicated, time-consuming, and makes it difficult to meet the need for automation.

[0003] Application content

[0004] To address the shortcomings of existing production technologies, the applicant provides a multi-point linkage quick clamping mechanism with a reasonable structure. This mechanism uses a linkage mechanism to drive the locking element, and through the movement of the linkage, it achieves the locking and releasing of the locking element. This effectively limits the position of the cover and has a real-time feedback function.

[0005] The technical solution adopted in this application is as follows:

[0006] A multi-point linkage quick clamping mechanism, applied to a container cover, includes a fixed bracket that maintains a constant relative position with the equipment and a linkage assembly that reciprocates around the fixed bracket.

[0007] The linkage assembly is equipped with a locking element; the locking element has two states as the linkage assembly swings: it engages with and locks the cover, and it releases the cover.

[0008] As a further improvement to the above technical solution:

[0009] The linkage assembly includes:

[0010] The cylinder, as a power source, is connected to external equipment.

[0011] The driving connecting rod is hinged to the piston rod end of the cylinder and is directly driven by the cylinder.

[0012] The transmission connecting rods are hinged to both ends of the driving connecting rods; the midpoint of each transmission connecting rod is hinged to the fixed bracket.

[0013] The driven link is hinged at both ends to the ends of the transmission link that are away from the driving link.

[0014] The active link, transmission link, and driven link form a parallelogram link group that oscillates around a fixed support.

[0015] The locking elements are symmetrically or arrayed on the driven link, and abut against the flange of the cover as the driven link moves up and down.

[0016] The fixed bracket is located on the side of the housing, and the driving link, transmission link and fixed bracket are coplanar; the driven link extends from the transmission link to the side wall of the housing, providing a mounting position for the locking element.

[0017] The driven link is provided with a locking block and a releasing block at both ends, and the distance between the locking block and the releasing block is smaller than the distance between the side rods on both sides of the fixed bracket.

[0018] The difference between the distance between the locking block and the releasing block and the distance between the rods on both sides of the fixed bracket is the length of the single-stroke swing path of the linkage assembly.

[0019] The driven link is equipped with a clamping sensor and a releasing sensor at both ends.

[0020] A position sensor is installed on the top of the housing.

[0021] There are at least two sets of connecting rod assemblies, which are symmetrically arranged on both sides of the housing.

[0022] The two sets of connecting rod assemblies are linked by the same cylinder.

[0023] The beneficial effects of this application are as follows:

[0024] In this application, a linkage mechanism is used to drive the locking element to abut against the cover and release it from the cover. The two states of abutting and releasing can be achieved simply by pushing the cylinder of the linkage mechanism, without the need for manual disassembly, thus realizing fully automatic control of the detachable setting of the cover.

[0025] The range of motion of the linkage mechanism in this application is limited by the fixed bracket. During the swinging process of the linkage mechanism, the locking block and the releasing block on the linkage mechanism will collide with the fixed brackets on both sides respectively. The movement path of the linkage is limited by the fixed brackets on both sides and the locking block and the releasing block on the linkage.

[0026] This application also includes multiple sensors to detect the movement status of the linkage structure in real time, thereby enabling fully automatic locking and unlocking of the cover. Attached Figure Description

[0032] The specific embodiments of this application are described below with reference to the accompanying drawings.

[0033] like Figure 1 As shown, the multi-point linkage quick clamping mechanism of this embodiment is applied to the container cover 1, including a fixed bracket 2 that maintains a constant relative position with the equipment, and a linkage assembly 3 that reciprocates around the fixed bracket 2.

[0034] The linkage assembly 3 is provided with a locking element 301; the locking element 301 has two states as the linkage assembly 3 swings: abutting the locking cover 1 and releasing the cover 1.

[0035] Linkage assembly 3 includes:

[0036] Cylinder 302, as a power source, is connected to external equipment.

[0037] The active connecting rod 303 is hinged to the piston rod end of the cylinder 302 and is directly driven by the cylinder 302.

[0038] The transmission link 304 is hinged to both ends of the drive link 303; the midpoint of each transmission link 304 is hinged to the fixed bracket 2.

[0039] The driven link 305 is hinged at both ends to the ends of the transmission link 304 that are away from the driving link 303.

[0040] The active link 303, the transmission link 304, and the driven link 305 form a parallelogram link group that swings around the fixed support 2.

[0041] The locking elements 301 are symmetrically or arrayed on the driven link 305 and abut against the flange of the cover 1 as the driven link 305 moves up and down.

[0042] The fixed bracket 2 is located on the side of the cover 1. The active connecting rod 303 and the transmission connecting rod 304 are coplanar with the fixed bracket 2. The driven connecting rod 305 extends from the transmission connecting rod 304 toward the side wall of the cover 1, providing an installation position for the locking member 301.

[0043] The driven link 305 has a locking block 306 and a releasing block 307 at both ends, and the distance between the locking block 306 and the releasing block 307 is smaller than the distance between the side rods on both sides of the fixed bracket 2.

[0044] The difference between the distance between the locking block 306 and the releasing block 307 and the distance between the two rods on both sides of the fixed bracket 2 is the length of the single-stroke swing path of the linkage assembly 3.

[0045] The driven link 305 is provided with a clamping sensor 4 and a releasing sensor 5 at both ends.

[0046] A position sensor 6 is installed on the top of the housing 1.

[0047] At least two sets of connecting rod assemblies 3 are provided, and the two sets of connecting rod assemblies 3 are symmetrically arranged on both sides of the housing 1.

[0048] The two sets of connecting rod assemblies 3 are linked by the same cylinder 302.

[0049] The specific structure and working principle of this application are as follows:

[0050] like Figure 1 and Figure 2 The diagram shown is a structural schematic of the single-link assembly 3 of this application, wherein... Figure 1 This is a schematic diagram of the locking cover 1 of the connecting rod assembly 3. Figure 2 A schematic diagram of the structure of the connecting rod assembly 3 with the cover 1 loosened.

[0051] by Figure 1 Taking the link assembly 3 as an example, the specific structure of the link assembly 3 will be explained.

[0052] The installation of the single linkage assembly 3 is based on the fixed bracket 2. The fixed bracket 2 can be installed on an external frame using fasteners such as screws. Details are omitted in this embodiment.

[0053] The shape of the fixed bracket 2 is referenced. Figure 3 The bracket has a double-layer structure, and the distance between the two layers is the space for installing the connecting rod assembly 3. The main body shape of the fixed bracket 2 is as follows: Figure 1 As shown, it includes side rods on both sides, and the top of the side rods on both sides is connected by a top rod.

[0054] At the bottom end of the side rod of the fixed bracket 2, a transmission connecting rod 304 is hinged to each of them, according to... Figure 1 , Figure 2 In the middle position, the bottom ends of the two transmission connecting rods 304 are hinged to the driving connecting rod 303, and the top ends of the two transmission connecting rods 304 are hinged to the driven connecting rod 305, forming as follows: Figure 1 Figure 2 The parallelogram linkage shown has four vertices that are rotatable hinges.

[0055] To limit the swing amplitude of the connecting rod assembly 3, locking blocks 306 and releasing blocks 307 are respectively provided at both ends of the driven connecting rod 305. When the position sensor 6 senses the cover, the cylinder 302 retracts, and the connecting rod assembly rotates to... Figure 1 In the specified state, the locking block 306 abuts against the side rod of the fixed bracket 2, reaching the displacement limit state, at which point the locking element 301 also presses against the cover. When the cylinder 302 receives the release signal, the connecting rod assembly 3 rotates to... Figure 2 In the current state, the loosening block 307 on the left side of the center position in the figure abuts against the other side rod of the fixed bracket 2. At this time, the height of the parallelogram structure of the connecting rod assembly 3 becomes shorter, leaving space to facilitate the removal of the cover 1.

[0056] Reference Figure 3 The cover 1 has a flange, and the locking member 301 provided on the driven link 305 is used to tighten the flange, pressing the cover 1 from bottom to top against the desired surface.

[0057] A certain gap is provided between the fixed bracket 2 and the cover 1 to facilitate the removal of the loosened cover 1; the fixed bracket 2, the active connecting rod 303 and the transmission connecting rod 304 in a set of connecting rod assemblies 3 are located in the same vertical plane; the driven connecting rod 305 extends from the top of the transmission connecting rod 304 toward the side close to the cover 1 until it extends to the underside of the flange of the cover 1, and the locking member 301 is provided at the driven connecting rod 305 below the flange of the cover 1 to provide a larger pressing area.

[0058] like Figure 3 As shown, the locking member 301 includes a screw 308 that passes through the driven connecting rod 305, and a locking nut 309 is disposed on the screw 308 to adjust the height of the locking member 301 and achieve limiting. A nylon sleeve 310 is provided at the top of the screw 308 to increase the contact area between it and the flange of the cover 1 and reduce the damage to the cover 1 caused by excessive local stress.

[0059] Cylinder 302 serves as a power source, driving the active connecting rod 303. In one embodiment of this application, two parts are provided on both sides of the housing 1. Figure 1 Figure 2 Linkage assembly 3, such as Figure 3 As shown. In order to ensure that the two connecting rod assemblies 3 are locked and released synchronously, in this embodiment, a cylinder 302 is used as a power source. A rod is hinged between the active connecting rods 303 in the two connecting rod assemblies 3 as a synchronizing rod 7. The cylinder 302 pushes the synchronizing rod 7, which can realize the simultaneous locking or releasing of the two connecting rod assemblies 3.

[0060] As an alternative implementation, the synchronizing rod 7 can be fixedly connected to the active connecting rod 303, or it can be rotatably connected to the active connecting rod 303. As long as relative rotation between the active connecting rod 303, the transmission connecting rod 304, and the driven connecting rod 305 can be achieved, the locking effect will not be affected.

[0061] The advantage of this application is that it uses a cylinder 302 to achieve multi-point pressing and limiting on both sides of the cover 1. Compared with the traditional multi-point fastening and limiting, it is easier to operate and the fastening force is more uniform at all points.

[0062] The above description is an explanation of this application and not a limitation thereof. The scope of this application is defined by the claims. Within the scope of protection of this application, any form of modification may be made.
