Detailed Description
Referring to fig. 1 and 2, two structural embodiments of a connecting member for a display frame of the present invention include an insert rod 1 for being axially inserted into a frame section of the display frame, a pressing member 2, and a fastening member 3, wherein a wall surface of one side of the insert rod 1 is provided with an installation groove 11 extending along an axis of the insert rod 1, as shown in fig. 1 and fig. 2, the inserting rod 1 is a straight rod or a right-angled bent rod, which is applied to the butt joint or corner connection of the frame, respectively, the installation groove 11 can be a single-section continuous extension shape or a corresponding multi-section extension shape, the top pressing member 2 is installed in the installation groove 11 in a matching manner and can elastically extend or elastically move to protrude from the outer wall surface of the inserting rod 1, the inner bottom surface of the installation groove 11 is provided with a connecting hole 12 penetrating through the inserting rod 1, the fastening member 3 is installed in the connecting hole 12, and one end of the fastener 3 can protrude out of the outer wall surface of the inserted bar 1 from the opening of the mounting groove 11 in a position-adjustable manner, and the jacking piece 2 and the fastener 3 are respectively positioned in the mounting grooves 11 of bar bodies at two ends of the inserted bar 1.
When the display frame is assembled, one end of the inserted bar 1, which is provided with the fastener 3, is inserted into an axial slot at one end of two frame profiles to be connected with the display frame, the inner walls of the slots of the frame profiles are matched and close to the inserted bar 1, and meanwhile, a slot which is smaller than the inserted bar 1 is formed in one inward side of the frame profiles, the fastener 3 is enabled to protrude out of the outer wall surface of the inserted bar 1 from the mounting groove 11 and be connected with or abut against the slots of the frame through the position movement of the fastener 3, so that the interaction of the fastener 3 towards the inner walls of the slots can enable the inserted bar 1 to be tightly connected with the frame profiles, for example, the fastener 3 can be designed into an ejector pin structure, the other side wall surface of the opening of the mounting groove 11 and the inner wall surface of the slots are enabled to abut against through the top end and the inner walls of the slots rigidly, or the fastener 3 can, the other end of the fastener 3 is connected with the connecting hole 12, so that the freedom degree of the inserted bar 1 in the frame section bar can be locked to realize fastening, if the connecting hole 12 is a blind hole, the fastener 3 can be pushed to be connected with the inner wall of the slot through an elastic element acting structure, the connecting hole 12 can also be a through hole, and the fastener 3 can be operated from the notch of the slot; then inserting one end of the inserted link 1, which is provided with the jacking member 2, into the same axial slot of another section frame, and along with the jacking member 2 being placed into the slot, the jacking member 2 protrudes out of the mounting groove 11 and abuts against the inner wall of the slot under the action of elastic force, so that the inserted link 1 is jacked against the inner wall of the slot on the other side of the opening of the mounting groove 11, and meanwhile, the surface of the jacking member 2 has enough static friction force and dynamic friction force with the stroke of the inner wall of the slot to prevent the inserted link 1 from easily coming out of the frame section, the jacking member 2 can be an elastic structure such as a reed, and the jacking member 2 can also be a rigid member which is elastically connected with; when the display frame is disassembled, the frame section bar at one end of the inserted rod 1 where the inserted jacking part 3 is located is firstly pulled out, then the frame section bar at the other end is pulled out by operating the loosening fastening part 3, and therefore the situation that the connecting part is detained in the frame section bar at which end in a clamping mode or is in flying separation when the connecting part is pulled out can be avoided.
Preferably, the pressing member 2 is a strip-shaped plate, at least two springs 22 and two screws 21 are arranged between the bottom surface of one pressing member 2 and the mounting groove 11, the springs 22 and the screws 21 are symmetrically distributed along the center of the pressing member 2, the screws 21 penetrate through the mounting groove 11 from the through hole at the other side of the inserting rod 1 to be in threaded connection with the pressing member 2, the screw heads of the screws 21 can be clamped with the outer wall of the inserting rod 1, two ends of the springs 22 simultaneously abut against or connect the inner bottom surface of the mounting groove 11 and the bottom surface of the pressing member 2, the pressing member 2 is supported to elastically protrude or press into the mounting groove 11, the range that the jacking part 2 can protrude from the mounting groove 11 can be limited and set through the clamping action of the screw head of the screw 21 and the outer wall of the inserted link 1, and the corresponding protruding part of the jacking part 2 is adjusted, so that the inserted link 1 is not difficult to insert into the slot of the frame section, and the jacking part 2 has enough elastic jacking force to abut against the wall surface of the slot; at least two groups of springs 22 and screws 21 are symmetrically connected to keep the pressing member 2 stably and elastically acting, so that the surface of the pressing member 2 can be used as a pressing surface to be elastically pressed to the maximum extent.
The inner bottom surface of the mounting groove is provided with a blind hole 13 corresponding to the spring 22, the lower end of the spring 22 is correspondingly arranged in the blind hole 13, the degree of freedom of the spring 22 is limited, the spring 22 can only extend and retract along the axial direction, the phenomenon that the spring 22 inclines or biases to reduce the axial elastic force is avoided, and the jacking part 2 is ensured to have enough elastic supporting force.
The screw 21 is a countersunk screw, the through hole of the inserted bar 1 is also a counter bore corresponding to the screw 21, and the countersunk screw is matched with the counter bore to keep the screw 21 at the central position, so that the top pressure piece 2 is prevented from deviating.
The surfaces of the two ends of the jacking part 2 are inclined planes which are flattened and extended outwards, so that the jacking part 2 can be guided to insert or pull out the slot of the frame profile along with the inserted rod 1 when the connection is convenient, the deviation of the jacking part 2 is reduced, and the elastic butt joint of the jacking part 2 is ensured to be better carried out.
The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the above embodiments, and the technical effects of the present invention should fall within the protection scope of the present invention as long as the technical effects are achieved by any of the same or similar means.
