CN201517337U - Split mounting type door - Google Patents

Abstract

A split mounting type door comprises a door frame enclosed by a door frame strip (1) with 45 degree corner angle at two ends, a door panel (2) and a back plate (3) and a polymeric material foaming layer in the door frame, characterized in that the door comprises corner guards (5) on the corners of the door frame and two adjacent door frame strips (1) are inserted into the corner guards (5). The split mounting type door conquers the problem of the prior split mounting type door that the prior split mounting type door needs secondary processing. The notch of the door frame strip is hidden in the corner guard to greatly improve the appearance of the four corners of the door and eliminate the discharged and rework due to back split-mounting quality of the door frame strip, thus the production cost is reduced and the production efficiency is increased.

Description

A kind of pin-connected panel door

Technical field

The utility model relates to the door body on the refrigeration equipments such as being used for refrigerator or wine cabinet, more particularly, relates to a kind of pin-connected panel door.

Background technology

The door body of general refrigerator (or wine cabinet) is made up of doorframe, panel, inner bag, heat insulation layer.For doorframe, the integral molded plastic formula arranged, the splicing structure formula is also arranged.The doorframe of integral molded plastic formula does not have seam for four jiaos, good looking appearance, still, the doorframe of integral molded plastic formula is owing to be the plastics single injection-moldeds, and a kind of specification need be opened a mold separately, and mould input expense is big, the product cost height can not be general, brings burden for simultaneously manufacture control, storage.The doorframe of pin-connected panel, press the length and width size cutting extrusion profile of doorframe after, be spliced into rectangle frame with cutting out four good extrusion profiles.The material of extrusion profile has plastic materials such as PVC, ABS, and metal material such as aluminium alloys are also arranged.This pin-connected panel doorframe only needs a kind of section bar mould and side cut instrument, and cost of manufacture is low, and still, pin-connected panel door body assembling part has seam, and seam is difficult evenly, butt joint is difficult neat.Its main cause is because general processing enterprise is difficult to guarantee the degree of accuracy of section bar corner cut, caused after the cutting angle or greater than 45 ° or less than 45 °, make that spliced slit is inhomogeneous, extrusion profile very easily slides relatively along contact surface in the process of assembly unit, cause dislocation, shown in accompanying drawing 2-3.Both of these case greatly reduces the aesthetics of a body, particularly also can form the sharp basil after the butt joint corner dislocation of door body, easily the user is caused personal injury and is complained.Some processing enterprise can avoid this kind injury to basil secondary operations such as polish, but for the producer, has both destroyed the attractive in appearance of door body, has spent time and manpower again.

Summary of the invention

The technical problems to be solved in the utility model is, at the deficiency that above-mentioned prior art exists, provides a kind of handling ease, pin-connected panel door elegant in appearance, to overcome the problem of present assembly unit Men Changxu secondary operations.

The technical solution adopted in the utility model is, a kind of pin-connected panel door is provided, comprise the caash bar, door face board of the 45 ° of corner cuts in two ends, the door frame that the back plate is surrounded, it in door frame the polymeric material foaming layer, it is characterized in that, also comprise the corner protector that is located on four jiaos of the door frames, described adjacent in twos caash bar inserts in the corner protector.

In the above-mentioned pin-connected panel door, described corner protector has been established the groove of guiding and position-limiting action.

In the above-mentioned pin-connected panel door, the front of described caash bar and lateral surface are cut edge and are hidden by corner protector.

In the above-mentioned pin-connected panel door, also comprise the connection angle bar, two right-angle sides of described connection angle bar are separately fixed on the adjacent in twos caash bar.

In the above-mentioned pin-connected panel door, the material of described corner protector be plastics or metal

Compared with prior art, refrigerator of the present utility model has the following advantages:

1) otch of caash bar is all ensconced in the corner protector, improves the outward appearance at Men Tisi angle greatly, and has eliminated scrapping, reprocessing of in the past causing owing to the caash bar assembly unit is of poor quality, and cost of production is reduced, and enhances productivity.

2) the utility model is simple in structure, and is practical generous.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Shown in Fig. 1-3 is the shortcoming of present assembly unit door signal and existence.Fig. 1 is the assembly unit door, and the caash bar of all cutting 45 ° of corner cuts by four two ends is spliced into doorframe.Gap shortcoming when Fig. 2 illustrates the caash bar corner cut less than 45 ° after the assembly unit.The assembly unit door of Fig. 3 extrusion profile in the process of assembly unit slides relatively along contact surface, causes wedge angle outstanding, easily scratch user's hand.

In order to overcome the problems referred to above that the assembly unit door exists, institute as shown in Figure 4, assembly unit door of the present utility model is mainly by caash bar 1, door face board 2, plate 3 (or refrigerator doors inner bag) is formed behind the door, door face board 2, is foaming layer between the plate 3 behind the door.On caash bar has, down, a left side, right four, caash bar is to install with assembly unit after 45 ° of corner cuts, in order to block the slit of 45 ° of cuttings of caash bar splicing place, two caash bars insert corner protector 5 and splice, below with the structure and the effect that are spliced into example explanation corner protector 5 of upper door frame and right caash bar: corner protector 5 is the splicing seams that are used for surrounding caash bar, comprise, the 45 ° R-joining As of right caash bar on door body front, with last, the seam B that right caash bar joins at the side surface of the upper surface of upper door frame and right caash bar, by orthogonal R-joining A and seam B is the strip corner protector 5 that benchmark forms to both sides translation same distance respectively, wherein to the both sides translation, seam B is respectively at the upper surface of moulding of calling on the doorframe front face surface for R-joining A, the side surface of right caash bar left and translation downwards.Intersect rounding off on formed mutually perpendicular three ribs on three surfaces.Village's material of corner protector 5 can be plastics or metal, and there is groove 7 both sides, see shown in Figure 5.During assembling, moulding and right caash bar insert the groove 7 of corner protector both sides respectively to the doorstep, and be fastening in order to strengthen, also add and connect angle bar 6, connecting angle bar 6 is support plates of right angle type, and two right-angle sides all have screw hole, with screw 4 it are contained in the adjacent in twos Men Jiao position that caash bar was combined into during installation.Such structure just make adjacent in twos caash bar directly contact become contacting of caash bar and corner protector, because the corner protector groove has encased the end face of caash bar section bar, contact slit crested, so no matter evenly whether the slit, can not influence the outward appearance of a body, and encased by corner protector by the basil of section bar, when also having avoided section bar that dislocation is installed to user's injury.
