Novel foaming positioning clamp for refrigerator cabinet

Abstract

This utility model discloses a novel foam positioning fixture for refrigerator cabinets, belonging to the field of foam fixtures. It includes an L-shaped plate, a clamping mechanism mounted on top of the L-shaped plate, and a base plate mounted on the bottom of the L-shaped plate. Universal wheels are fixedly connected to all four sides of the bottom of the base plate. Through the clamping mechanism and universal wheels, this utility model places the refrigerator cabinet on a placement plate. After the cabinet foaming process is completed, the first hydraulic rod slowly rises, causing the fixed plate to slide within the grooves on the surface of the U-shaped rod. This causes one end of the U-shaped rod to rotate on the top of the top plate, while the other end causes the side plate to move away from the surface of the refrigerator cabinet. Finally, as the device continues to rise, the limiting rods are restricted by the grooves, ultimately causing the top plate to rise and the fixture to detach. This prevents the refrigerator cabinet from shifting during detachment, reducing the risk of the cabinet falling off the placement plate. Simultaneously, the universal wheels around the base plate allow for convenient movement of the device.

Description

Technical Field

[0001] This utility model relates to the field of foaming fixture technology, specifically a novel foaming positioning fixture for refrigerator bodies. Background Technology

[0002] As freezer products trend towards larger capacity and energy efficiency, traditional foam positioning technology is facing significant challenges. Generally, a freezer clamping box consists of a shell and a foam layer located inside the shell, and the foaming process of the shell requires specialized foaming fixtures.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN220030958U) discloses a novel foaming clamp for a freezer body, comprising a fixed base plate, a shock-absorbing support plate, a shock-absorbing damper, a shock-absorbing telescopic spring, and an adjustable freezer body foaming clamp assembly. The adjustable freezer body foaming clamp assembly includes a fixed stand, a drive motor, a rotary transmission threaded rod, a threaded rod support plate, a guide limit rod, a connecting plate groove, a connecting plate slider, a movable connecting plate, a foaming box support plate, a freezer body clamping foaming box, and a freezer body support platform. This utility model belongs to the field of freezer technology. The shock-absorbing damper and shock-absorbing telescopic spring facilitate shock absorption and protection during operation, while the adjustable freezer body foaming clamp assembly enables convenient and automated clamping and sealing for foaming treatment of the freezer body.

[0004] While the aforementioned patent enables convenient and automated clamping and sealing of the freezer body using an adjustable foaming clamp assembly, the resulting tight fit between the freezer body and the inner wall of the foaming box after foaming means that the freezer body can easily move along with the foaming box when it is separated from the cabinet. This can cause it to deviate from the support platform, increasing the risk of the freezer body falling and being damaged. Furthermore, the foaming clamp is difficult to move, often requiring the use of lifting equipment, which makes operation inconvenient.

[0005] The existing technology has the following problems: Therefore, this utility model provides a novel foam positioning fixture for refrigerator cabinets to solve the above problems. Utility Model Content

[0006] This utility model provides a novel foam positioning fixture for refrigerator cabinets, aiming to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: including an L-shaped plate and a clamping mechanism mounted on the top of the L-shaped plate, and a base plate mounted on the bottom of the L-shaped plate, wherein universal wheels are fixedly connected to the bottom four sides of the base plate; The clamping mechanism includes a first hydraulic rod fixedly installed on one side of the L-shaped plate and a fixed plate fixedly connected to the output end of the first hydraulic rod, as well as a top plate mounted below the fixed plate. The top of the top plate is rotatably connected to four U-shaped rods, and one end of each of the four U-shaped rods is rotatably connected to four side plates. A sliding groove is provided on one side of the surface of each of the four U-shaped rods, and a limit rod is slidably connected inside the sliding groove. One end of the limit rod is fixedly connected to one side of the fixed plate.

[0008] As a preferred technical solution of this application, cylinders are fixedly connected to the top four sides of the top plate, the cylinders penetrate the fixing plate, and anti-detachment blocks are fixedly connected to the top of the cylinders.

[0009] As a preferred technical solution of this application, a spring is fixedly connected to one side of the side plate, a buffer rod is sleeved inside the spring, and one end of the spring is fixedly connected to one side of the U-shaped rod.

[0010] As a preferred technical solution of this application, a placement plate is fixedly connected to one side of the top of the base plate, and the placement plate is located directly below the top plate.

[0011] As a preferred technical solution of this application, a rectangular groove is provided at the bottom of the base plate, and a second hydraulic rod is fixedly installed on the inner wall of the rectangular groove. The output end of the second hydraulic rod is fixedly connected to a limit plate.

[0012] As a preferred technical solution of this application, the bottom of the base plate is provided with grooves on both sides, and a fixing rod is slidably connected inside the groove, with one end of the fixing rod rotatably connected to one side of the limiting plate.

[0013] As a preferred technical solution of this application, a plurality of rubber pads are fixedly connected to the bottom of the limiting plate, and the bottom of the rubber pads is provided with concave and convex textures.

[0014] Compared with the prior art, the beneficial effects of this utility model are: With the clamping mechanism and casters, the box is placed on the placement plate. After the box foaming is completed, the first hydraulic rod slowly rises, causing the fixed plate to slide around the limiting rods in the grooves on the surface of the U-shaped rod. This causes one end of the U-shaped rod to rotate on the top of the top plate, while the other end causes the side plate to move away from the box. Finally, as it continues to rise, the limiting rods are restricted by the grooves, thus causing the top plate to rise and the clamp to disengage. This prevents the box from shifting when disengaging from the clamp, reducing the risk of the box falling off the placement plate. At the same time, the casters around the bottom plate allow for easy movement of the device without the need for external lifting equipment. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figure 1-5 The present invention discloses a novel foam positioning fixture for a freezer body, comprising an L-shaped plate 1 and a clamping mechanism 2 mounted on the L-shaped plate 1, and a base plate 3 mounted on the bottom of the L-shaped plate 1. The base plate 3 has casters 4 fixedly connected to all four sides of its bottom. The clamping mechanism 2 includes a first hydraulic rod 201 fixedly mounted on one side of the L-shaped plate 1 and a fixed plate 202 fixedly connected to the output end of the first hydraulic rod 201, and a top plate 203 mounted below the fixed plate 202. Four U-shaped rods 204 are rotatably connected to the top of the top plate 203. Four side plates 205 are rotatably connected to one end of each of the four U-shaped rods 204. A groove is provided on one side of the surface of each of the four U-shaped rods 204, and a limiting rod 206 is slidably connected inside the groove. One end of the limiting rod 206 is fixedly connected to one side of the fixed plate 202. The top of the top plate 203 is fixedly connected to the four sides of the top, and the cylinders 5 penetrate the fixed plate 202. The top of the cylinders 5 is fixedly connected to the anti-detachment block 6. A spring 7 is fixedly connected to one side of the side plate 205. A buffer rod is sleeved inside the spring 7. One end of the spring 7 is fixedly connected to one side of the U-shaped rod 204. A placement plate 8 is fixedly connected to one side of the top of the base plate 3, and the placement plate 8 is located directly below the top plate 203; A rectangular groove is provided at the bottom of the base plate 3. A second hydraulic rod 9 is fixedly installed on the inner wall of the rectangular groove. The output end of the second hydraulic rod 9 is fixedly connected to a limit plate 10. The bottom of the base plate 3 has grooves on both sides, and a fixing rod 11 is slidably connected inside the groove. One end of the fixing rod 11 is rotatably connected to one side of the limiting plate 10. Several rubber pads are fixedly connected to the bottom of the limiting plate 10, and the bottom of the rubber pads is provided with concave and convex textures.

[0019] The working principle of a novel foam positioning fixture for a freezer body based on the embodiment is as follows: the body is placed on the placement plate 8, the first hydraulic rod 201 is activated to drive the fixing plate 202 to slowly descend, so that the top plate 203 first contacts and fits the top of the body. At the same time, the fixing plate 202 slides on the cylindrical surface 5 on the top of the top plate 203 to keep the fixing plate 202 descending vertically. As the fixed plate 202 continues to descend, it causes the limiting rods 206 around it to slide within the grooves on the surface of the U-shaped rod 204. This causes one end of the U-shaped rod 204 to rotate on top of the top plate 203, while the other end causes the side plate 205 to adhere to the surface of the box. The spring 7 keeps the side plate 205 in a vertical position, facilitating its adherence to the box surface. When the side plate 205 adheres to the top and the perimeter of the placement plate 8, the spring 7 is compressed, thus completing the enclosure of the box. At this point, the first hydraulic rod 201 is closed. After moving the device to a suitable position, open the second hydraulic rod 9 to push the limiting plate 10 to contact the ground. At the same time, the fixing rods 11 on both sides of the limiting plate 10 slide on both sides, while the other end of the fixing rod 11 slides inside the groove. This ensures that the limiting plate 10 is difficult to rotate after contacting the ground, thereby increasing the stability of the limiting plate 10.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
