Detailed Description
Example 1: the embodiment is a linear butt joint clamping groove connecting piece for connect object A and object B, including cell body 1, elasticity clamping groove spare 2 and plugboard 3, wherein object A connects cell body 1, and plugboard 3 is connected to object B, and plugboard 3 passes through elasticity clamping groove spare 2 and is connected with cell body 1.
In the embodiment, the trough body 1 is internally provided with a connecting groove 1-1 in a through length manner, two sides of the notch part of the connecting groove are respectively provided with a trough body step 1-2, and a trough body channel 1-3 is formed between the trough body steps 1-2 at two sides of the notch. The upper end surface 1-2-1 of the groove body step 1-2 is provided with a groove body step guiding inclined plane 1-2-2 which inclines downwards towards the groove body channel 1-3 near the side edge 1-3 of the groove body channel.
In the embodiment, an elastic clamping groove piece 2 is arranged in a connecting groove 1-1 of a groove body 1, and the width L2 of the elastic clamping groove piece is larger than the width L1 of a channel 1-3 of the groove body, so that the elastic clamping groove piece cannot pass through the channel 1-3 of the groove body.
In this embodiment, the elastic slot member 2 is usually provided with a slot 2-1 therein, the slot opening of the slot is provided with slot steps 2-2 on both sides, and a slot channel 2-3 is formed between the slot steps 2-2 on both sides. A slot step guide inclined plane 2-2-2 which inclines downwards towards the slot channel 2-3 is arranged on the upper end surface 2-2-1 of the slot step 2-2 and is close to the side edge of the slot channel 2-3.
In the embodiment, the middle of the bottom surface of the elastic clamping groove member 2 is provided with a supporting boss 2-4, the elastic clamping groove member 2 is supported on the bottom surface of the connecting groove 1-1 through the supporting boss 2-4, and gaps are reserved between the lower part of the elastic clamping groove member and the bottom surface of the connecting groove 1-1 and at two sides of the supporting boss 2-4 and can provide deformation spaces when the groove walls at two sides of the elastic clamping groove member 2 are deformed under pressure.
In this example, the distance between the bottom surface of the support boss 2-4 and the upper end surface 2-2-1 of the slot step is basically the same as the distance between the bottom surface of the connecting groove 1-1 and the lower end surface 1-2-3 of the slot step, and when the elastic slot member 2 is supported on the bottom surface of the connecting groove 1-1 by the support boss 2-4, the upper end surface 2-2-1 of the slot step is contacted and jointed with the corresponding lower end surface 1-2-3 of the slot step. This measure makes the elastic slot-locking member 2 and the connecting slot 1 not relatively displace when the connecting body 3 is pulled upwards, thereby ensuring that no crack is generated at the interface when the two objects A, B are pulled.
In this example, the horizontal distance from the intersection O1 of the left side surface of the support boss and the bottom surface of the slot member to the intersection O2 of the upper end surface of the slot step and the guide slope of the slot step is greater than 0 (i.e., the θ angle in fig. 6 is greater than 0), so that when the elastic slot member receives the extrusion force generated in the downward movement process of the connecting member, and the point O1 on the boss is taken as the rotation center, the edge point O2 of the elastic slot passage is gradually reduced from the initial stationary point when the elastic slot member is rotationally deformed by the extrusion force, so that the highest point O2 of the arc line is not blocked by the stage of connecting the slot body, and no deformation space allowance in the up-down direction (i.e., the height of the elastic slot member is equal to the height of the connecting slot) is left, and thus, when the plugboard is pulled, two connected objects are not cracked due to the deformation space allowance in the up-down direction reserved in the connecting slot.
The width of the plug board 3 and the connector 3-1 is slightly smaller than the width of the channel of the groove body, and the width of the connector 3-1 is larger than the width of the channel of the groove and smaller than the width of the clamping groove; the width of the transition section 3-2 is smaller than that of the connector, and the width and the height of the transition section are matched with those of the channel of the clamping groove.
In this embodiment, since the width of the transition section 3-2 is smaller than the width of the connector, connector steps 3-1-2 matched with the slot steps 2-2 on both sides of the elastic slot member 2 are formed on both sides of the upper end of the connector 3-1.
In the embodiment, the upper end face 3-1-2-1 of the connector step 3-1-2 of the connector step is matched with the lower end face 2-2-3 of the clamping groove step 2-2, the included angle alpha between the upper end face 3-1-2-1 of the connector step and the upward moving direction of the plugboard is a right angle or an acute angle, when the plugboard is pulled to move upwards, the upper end face 3-1-2-1 of the connector step is tightly attached to the lower end face 2-2-3 of the clamping groove step, but the connector cannot push the clamping groove step 2-2 open, so that the plugboard cannot be separated from the elastic clamping groove piece.
In the embodiment, the end part of the plug-in board 3 is connected with the connector 3-1 through the transition section 3-2, the two sides of the lower end of the connector 3-1 are respectively provided with a connector guide inclined plane 3-1-1, and the connector guide inclined plane 3-1-1 can be matched with the groove step guide inclined plane 1-2-2 and the clamping groove step guide inclined plane 2-2-2 to guide the connector into the corresponding groove channel and the clamping groove channel.
In this embodiment, when the inserting plate 3 is combined with the elastic slot member 2 through the connector 3-1, the upper end surface 2-2-1 of the slot step 2-2 in the elastic slot member is matched with the lower end surface 1-2-3 of the slot step 1-2 in the slot body 1, and the included angle beta between the upper end surface of the slot step and the upward moving direction of the inserting plate is a right angle, when the inserting plate is pulled upwards, the upper end surface of the slot step is tightly attached to the lower end surface of the slot step to limit the deformation of the slot step part of the elastic slot member, and the connector is prevented from being separated from the elastic slot member.
In order to facilitate the installation of the elastic groove clamping piece, the groove body 1 is formed by welding and connecting two parts in the embodiment, and is provided with a groove wall part I1 a containing one side groove wall and a groove wall part II 1b containing the other side groove wall, and the parts I and II of the groove walls are welded and connected through a welding seam 1c to form the groove body. The groove wall part I1 a and the groove wall part II 1b on the other side are welded and connected through a welding seam 1-4 to form a groove body 1-1 after the elastic clamping groove part 2 is placed into the connecting groove 1-1. And welding the groove wall part I1 a and the groove wall part II 1b after the groove wall parts I1 a and II 1b are tightly attached to a connecting point P at the welding seams 1-4.
The connection method of the linear type butt joint clamping groove connecting piece in the embodiment is as follows: the connector end of plugboard inserts downwards from the cell body passageway of cell body, and the connector continues the downstream after contacting with elastic clamping groove spare, makes elastic clamping groove spare take place deformation under the effect of direction inclined plane, extrudes behind the draw-in groove step of opening both sides, and the connector gets into the joint groove, realizes being connected of plugboard and elastic clamping groove spare, because elastic clamping groove spare can't pass through the cell body passageway to make plugboard and the unable separation of cell body, the realization is connected.
In this embodiment, because plugboard thickness and cell body passageway thickness looks adaptation, the control is controlled to control about the plugboard, can prevent that the plugboard from rocking about relative cell body after being connected with the cell body.
