Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration equipment, in particular to auxiliary tooling for producing freezers. Background Art
[0002] A freezer, also called a refrigerator, is a device that preserves food, drinks and other items at low temperatures. It is generally large in size and is often used in commercial scenarios. Most freezers are top-opening and have sliding glass. During the production process, workers are required to put the glass in place when installing the sliding glass. Because the glass is relatively smooth and heavy, manual operation is time-consuming and labor-intensive, and there is also a risk of slipping. Therefore, it is necessary to provide auxiliary devices.
[0003] At present, suction cups are mostly used to assist in picking up glass. For example, the patent with application number "CN2013103512401" discloses a suction cup, in which a pull rod is connected to the back side of the suction cup body, and the pull rod passes through a transfer body and is connected to a flip handle. When the handle is retracted to the transfer body, a negative pressure chamber is formed and the air in the negative pressure chamber is exhausted as much as possible; when the handle is flipped away from the transfer body, the front side of the suction cup body is restored to quickly eliminate the negative pressure chamber. This is a conventional suction cup working form; that is, the suction cup is driven to form a negative pressure adsorption or a pressure-free state by the movement of the pull rod, and the pull handle is pulled to lock the form of the pull rod.
[0004] In actual use, a single suction cup is unstable in adsorbing glass and is prone to imbalance, so multiple suction cups need to be used at the same time. However, since each suction cup is independent, the operation is somewhat inconvenient, and it is not easy to control the distance between the suction cups to ensure balance. In addition, the lifting handle uses the state of the cut angle and the flat surface of the pull rod to lock, which poses risks such as insecurity, accidental touch, and self-movement. For overall use, there is also the risk of accidental tooling falling off and loss of strength. Therefore, it is necessary to improve and design the auxiliary tooling for the installation of sliding glass in freezer production. Utility Model Content

[0046] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0047] Reference Figure 1-10 , an auxiliary tooling for freezer production, comprising two suction cups 1 connected as one by a telescopic rod 2; the two suction cups are arranged together, and the distance between the two suction cups can be adjusted and fixed according to the size of the installed freezer push-pull glass; so that it is more convenient to take and put, and the force on the glass can be more balanced. It can be understood that the bottom surfaces of the two suction cups 1 are located on the same surface.
[0048] Specifically, the telescopic rod 2 includes an outer rod 21 and an inner rod 22 of a sliding set; wherein the ends of the outer rod 21 and the inner rod 22 that are away from each other are respectively fixed on the outer ring side of a suction cup 1; and a tightening screw 23 is provided above the outer rod 21, which penetrates the outer rod 21 and presses the inner rod 22; and is used to adjust and lock the shape of the telescopic rod 2.
[0049] Preferably, the telescopic rod 2 is a flat structure; Figure 1 , 3 As shown in Figures 5, the flat telescopic rod 2 is adapted to the flat suction cup 1 and has a larger volume, thereby having higher strength and bearing capacity.
[0050] Furthermore, a fixed hand wheel 24 is provided at the top end of the tightening screw 23 to facilitate personnel to directly operate and rotate the tightening screw 23 .
[0051] Furthermore, a threaded barrel 25 adapted to the jacking screw 23 is fixedly arranged above the telescopic rod 2; the jacking screw 23 passes through the threaded barrel 25 and the outer rod 21 in sequence, and then presses the surface of the inner rod 22. By adding the threaded barrel 25, the force-bearing surface of the jacking screw 23 is increased, and the whole is more reliable and stable.
[0052] In some embodiments, an inverted U-shaped fixed handle 3 is provided above the suction cup 1; a pull rod 4 is provided at the center position above the suction cup 1, and a lifting handle 5 is hingedly provided on the pull rod 4; through the adjustment of the lifting handle 5, the suction cup is controlled to be in a suction state or a relaxation state.
[0053] Specifically, a connecting block 52 is provided at the lower end of the lifting handle 5, and the connecting block 52 is hinged to the pull rod 4 through a pin shaft 53; wherein, the bottom edge of the connecting block 52 facing outward is set as a cut corner 54 or chamfer.
[0054] Thus, when the lifting handle 5 is rotated inward to be upright, the pull rod 4 is pulled upward, the suction cup 1 generates suction, and the whole is in a suction operation state; when the lifting handle 5 is rotated outward, the pull rod 4 is contracted downward by the pulling force of the suction cup 1, and the whole is in a relaxed state.
[0055] Furthermore, a reinforcement ring 11 is provided at the center position above the suction cup 1 .
[0056] like Figure 2 The lower end surface of the lifting handle 5 is in conflict with the reinforcing ring 11 to prevent the connecting block 52 from directly rubbing against the top surface of the suction cup 1.
[0057] It is understandable that the reinforcement ring 11 is made of steel with relatively high hardness; it can be fixed on the suction cup 1, or directly movably mounted on the outside of the pull rod 4; wherein the center hole of the reinforcement ring 11 is larger than the outer diameter of the pull rod 4.
[0058] In some embodiments, a wave groove 31 is provided at the inner top of the fixed handle 3 to facilitate manual gripping of the fixed handle 3 .
[0059] In some embodiments, a locking tongue 6 is provided downward on the inner top surface of the fixed handle 3 and extends into the groove 51 above the lifting handle 5; the lifting handle 5 in the suction operation state is locked by the locking tongue 6 to avoid accidental release.
[0060] like Figure 1 , 2 , 5, and 6; in the relaxed state, the lifting handles 5 of the suction cups 1 on both sides rotate and tilt outward; when entering the suction operation state, the lifting handles 5 rotate inward. Correspondingly, adapted to the operation form of the lifting handles 5, the arc surface 61 of the locking tongue 6 is located at the inner side of the lower end.
[0061] Therefore, when the lifting handle 5 rotates inward, its top edge contacts the arc surface 61 of the locking tongue 6, causing the locking tongue 6 to retract upward; thereafter, the locking tongue 6 is inserted into the groove 51 above the lifting handle 5 to achieve locking.
[0062] It is understandable that a placement groove 32 is provided below the fixed handle 3 , and the locking tongue 6 slides vertically in the placement groove 32 ; a spring 62 is provided between the locking tongue 6 and the inner top surface of the placement groove 32 .
[0063] Preferably, a circular groove 33 is formed on the inner top surface of the placement groove 32 , and the top end of the spring 62 is fixed in the circular groove 33 .
[0064] Furthermore, a lever 63 is provided on the inner side of the lock tongue 6 to facilitate lifting the lock tongue 6 upwards to release the lock.
[0065] In some embodiments, a safety rope 7 is provided on the outside of the suction cup 1 .
[0066] like Figure 1 As shown, the safety rope 7 is tied to the operator's wrist and arm to provide protection when the operator's hand accidentally slips and avoids falling directly to the ground.
[0067] Furthermore, a binding ring 8 is provided at the end of the safety rope 7 for easy operation.
[0068] The binding ring 8 can be an adjustable structure such as Velcro, a strap, etc., or can be directly set in the form of a ring body and put on the arm.
[0069] When the utility model is used, the safety rope 7 or the binding ring 8 is tied to the operator's arm; the shape of the telescopic rod 2 is adjusted; the operator holds the fixed handle 3 of the two suction cups and places it on the inference glass; then, the lifting handle 5 is rotated inward to a vertical state, and the suction cup is in a suction operation state; at the same time, the locking tongue 6 is downwardly inserted into the groove 51 above the lifting handle 5 to lock it; the glass is transferred to the top of the freezer and installed in place; then, the lever 63 is moved to lift the locking tongue 6, the lifting handle 5 is rotated outward, the suction is released, the glass is released, and the device is held for the next operation.
[0070] In the utility model, two suction cups are arranged together, and the distance between the two suction cups is adjusted and fixed according to the size of the installed refrigerator sliding glass, which is more convenient when taking and placing, and the force on the glass can be more balanced; a flat telescopic rod 2 is arranged, which has a larger volume, higher strength and bearing capacity; a threaded cylinder 25 is added to increase the force-bearing surface of the tightening screw 23, and the whole is more reliable and stable; a reinforcing ring 11 is arranged to abut against the lower end surface of the lifting handle 5 to avoid friction on the top surface of the suction cup 1; a wave groove 31 is arranged to facilitate manual gripping of the fixed handle 3; a locking tongue 6 is arranged to lock the lifting handle 5 in the suction operation state to avoid accidental loosening; a safety rope 7 and a binding ring 8 are arranged to be tied to the wrist and arm of the operator, which can form a protection when the hand accidentally slips and avoid falling directly to the ground.
