Abstract
The utility model discloses an exhibition frame connecting lock which comprises a lock shell, a lock plate and an eccentric lock wheel, wherein two slots which extend from the middle to the front end are arranged on the lock plate; the two slots divide the lock plate into a left plate tongue, a middle plate tongue and a right plate tongue; the front ends of the left plate tongue, the middle plate tongue and the right plate tongue are provided with U-shaped hooks; both slots have two-section type structures; the width of the front section of each slot is larger than that of the rear section of the slot; the front of the middle plate tongue is narrower than the rear of the middle plate tongue; and a transition inclined surface is arranged between the front and the rear of the middle plate tongue. Because both slots of the exhibition frame connecting lock provided by the utility model have the two-section type structures, the width of the front section of each slot is larger than that of the rear section of the slot, the front of the middle plate tongue is narrower than the rear of the middle plate tongue, and the transition inclined surface is arranged between the front and the rear of the middle plate tongue, the width space occupied by the middle plate tongue is emptied completely compared with the traditional three-section type structure, and the left plate tongue and the right plate tongue have enough width, the strength of the left plate tongue and the right plate tongue is not lower than that of the middle plate tongue, and the exhibition frame has higher firmness.
Description
Technical field
The utility model relates to a kind of exhibition framework and connects lock.
Background technology
It is a kind of three-pawl lock of CN1225967 that China national Department of Intellectual Property discloses publication number on August 18th, 1999, this tool is by lock housing, jam plate, the eccentric lock wheel constitutes, there are two on the jam plate from the middle elongated slot that extends to front end always, and three plate tongues of two sides and centre about having on the formation jam plate, plate tongue front end is the U-shaped crotch, about two side plate tongue symmetries, elongated slot is not wide elongated slot, divide leading portion, three sections of stage casing and back segments, the two sections width in front and back equate that the stage casing width is big, thereby form in three plate tongues, two side plate tongue front portions are wide than the rear portion, and the intermediate plate back of tongue is anterior wide, has spike at the rear of intermediate plate tongue, spike is towards the place ahead, the spike nose is pressed on the loading end of lock housing inboard, and the inclined-plane of three plate tongues is close on the oblique bearing surface in lock housing the place ahead, and the width of the oblique bearing surface of lock housing is greater than the width on plate tongue inclined-plane.The elongated slot of this lockset is owing to be divided into leading portion, stage casing and back segment, and the two sections width in front and back equate, the stage casing width is big, therefore it is little more a lot of than intermediate plate tongue to cause elongated slot to separate the plate tongue width of the left and right sides in three plate tongues of gained, and the plate back of tongue width of the left and right sides is little more many than the front portion again, thereby the plate tongue of the left and right sides is damaged in the process of using easily.
Summary of the invention
The width distribution that technical problem to be solved in the utility model provides a kind of plate tongue more rationally, more firm exhibition framework connects lock.
For this reason, the exhibition framework that the utility model provides connects lock, comprise lock housing, jam plate, eccentric lock wheel, there are two on the jam plate from the middle elongated slot that extends to front end always, two elongated slots are divided into left plate tongue, intermediate plate tongue and right plate tongue with jam plate, left plate tongue, intermediate plate tongue and right plate tongue front end have the U-shaped crotch, two elongated slots are the two-part structure, the width of elongated slot leading portion is greater than the width of elongated slot back segment, intermediate plate tongue front portion is narrower than the rear portion, has the transition inclined-plane between intermediate plate tongue front portion and the rear portion.
Be the two-part structure because the exhibition framework that the utility model provides connects lock two elongated slots, the width of elongated slot leading portion is greater than the width of elongated slot back segment, and intermediate plate tongue front portion is narrower than the rear portion, has the transition inclined-plane between intermediate plate tongue front portion and the rear portion.Therefore compare the width spaces that traditional syllogic structure can fully occupy the intermediate plate tongue and vacate, make left and right sides plate tongue can occupy enough width, thereby make left and right sides plate tongue can access intensity, make its firmness better as many as the intermediate plate tongue.
Description of drawings
The exhibition framework that Fig. 1 provides for the utility model connects the structural plan schematic diagram of the jam plate of lock.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is that the exhibition framework that jam plate shown in Figure 1 is installed connects lock.
Fig. 4 is the structural representation after the exhibition framework among Fig. 3 connects lock and the exhibition framework is connected.
The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 is described, the exhibition framework that the utility model provides connects lock, comprise lock housing, jam plate 1, the eccentric lock wheel, there are two on the jam plate 1 from the middle elongated slot 2 that extends to front end always, two elongated slots are divided into left plate tongue 3A with jam plate, intermediate plate tongue 3B and right plate tongue 3C, left plate tongue 3A, intermediate plate tongue 3B and right plate tongue 3C front end have U-shaped crotch 4, two elongated slots 2 are the two-part structure, the width of elongated slot leading portion 2A is greater than the width of elongated slot back segment 2B, intermediate plate tongue 3B front portion is narrower than the rear portion, have transition inclined-plane 5 between intermediate plate tongue 3B front portion and the rear portion, left plate tongue 3A and right plate tongue 3C anterior all consistent (see that from figure left plate tongue 3A and right plate tongue 3C front portion are exactly left part among the figure, the rear portion is exactly a right side part among the figure) with left plate tongue 3A and right plate tongue 3C rear portion width.
As shown in Figure 1, the end of the U-shaped crotch 4 of intermediate plate tongue 3B front end is the trapezoidal shape that the end is wide, root is narrow in the present embodiment, and this structure is convenient to the intermediate plate tongue 3B exhibition framework of holding more.
