The first embodiment is as follows:
as shown in fig. 1 and 2, a fast-assembling lower wheel structure, include shell 1 and set firmly in the inside assembly pulley 2 of shell 1, be provided with storage tank 5 between shell 1 and the assembly pulley 2, the storage tank 5 is in the receipt has the locking plate 3 that is used for block to door leaf section bar, the length of locking plate 3 is greater than the width of shell 1, still be provided with on the shell 1 and be used for driving locking plate 3 reciprocating motion's on vertical direction driving piece, driving piece and 3 threaded connection of locking plate, set up the locking groove 6 that supplies locking plate 3 to stretch out on the lateral wall of shell 1.
The shell 1 comprises two side plates, the locking grooves 6 are respectively arranged on the two side plates, the length of the locking piece 3 is larger than the width between the two side plates, and the driving piece is in threaded connection with the locking piece 3. When the locking piece 3 is not required to be assembled, the whole locking piece is positioned in the accommodating groove 5, so that the installation space of the lower wheel structure can be prevented from being occupied; in the assembling process, the staff rotates the driving piece, locking plate 3 can be rotary motion along with the driving piece together, because when rotatory when certain angle, the both ends of locking plate 3 are contradicted respectively on the cell wall of storage tank 5, begin to be the reciprocating motion of vertical direction, stretch out locking groove 6 until the both ends of locking plate 3, the staff is adjusting the displacement of locking plate 3 in vertical direction according to the actual degree of depth in the joint groove of door leaf section bar, closely cooperate until locking plate 3 and joint groove, accomplish the assembly of lower round structure and door leaf section bar.
As shown in fig. 3, specifically, the driving member includes a fixing plate 8 and a bolt 4, the fixing plate 8 is disposed at the bottom of the housing 1, a screw hole 31 is formed in the middle of the surface of the locking plate 3, and the bolt 4 penetrates through the fixing plate 8 and is connected with the screw hole 31.
Through foretell mode, fixed plate 8 provides the installation basis for bolt 4, rotates bolt 4 and can directly drive locking plate 3 and realize the locking or the unblock state to the joint groove of door leaf section bar to realize the rapid Assembly of lower round of structure.
With reference to fig. 4 and 5, the locking plate 3 is described, wherein the locking plate 3 is provided with a contact block 7 for contacting the inner wall of the accommodating groove 5, and when two ends of the locking plate 3 respectively extend into the locking groove 6 and contact the side wall of the locking groove 6, the contact block 7 also contacts the inner wall of the accommodating groove 5.
Through the horizontal swing of the lateral wall restriction locking plate 3 of locking groove 6 to realize the ascending reciprocating motion of vertical side, conflict piece 7 set up and also have the same function, and locking plate 3 realizes reciprocating motion about the drive of bolt 4 through the lateral wall of the tip of self and conflict piece 7 jointly, reduces the wearing and tearing between locking plate 3 and the locking groove 6, thereby improves the life and the job stabilization nature of taking turns the structure down.
Of course, the locking plate 3 is not limited to the above-mentioned solution, and other structures are possible, as long as the two ends of the locking plate 3 can extend out of the locking groove 6, and the locking plate 3 can reciprocate up and down under the driving of the bolt 4, so as to lock with the locking groove of the door leaf profile.
In order to further enable the screw hole 31 on the locking plate 3 to be tightly matched with the bolt 4, an elastic member (not shown in the figure) is sleeved on the bolt 4, one end of the elastic member abuts against the fixing plate 8, the other end of the elastic member abuts against the locking plate 3, the elastic member plays a pre-tightening role in screwing connection between the screw hole 31 and the bolt 4, the locking plate 3 is prevented from being difficult to be rapidly driven to lock the clamping groove of the door leaf profile in the actual assembly process, and the elastic member is preferably a spring.
Specifically, the abutting block 7 includes a connecting portion 71 and an extending portion 73, one end of the connecting portion 71 is connected to the side wall of the locking piece 3, the other end of the connecting portion 71 is connected to the extending portion 73, the connecting portion 71 and the locking piece 3 are located on the same horizontal plane, and the extending portion 73 is vertically disposed at the end of the connecting portion 71.
In order to further improve the structural strength of the connecting portion 71 and the locking portion, a first rounded corner structure 74 is arranged between two side walls of the connecting portion 71 and a side wall inside the locking piece 3, and the first rounded corner structure 74 can play a role of buffering when the extending portion 73 abuts against a groove wall of the accommodating groove 5, so as to prevent the connecting portion 71 from being broken; a second fillet structure 72 is arranged between the top of the extension portion 73 and the top of the connecting portion 71, the second fillet structure 72 can play a role in buffering at the joint of the extension portion 73 and the connecting portion 71, and the arrangement of the first fillet structure 74 and the second fillet structure 72 can improve the structural strength and the working stability of the contact block 7.
In order to further improve the structural stability between the bolt 4 and the screw hole 31, a boss 9 is provided at the bottom inside the locking plate 3, and the boss 9 is provided along the opening of the screw hole 31 and is communicated with the screw hole 31, so as to prevent the problem that the bolt 4 has poor driving effect due to the small contact area with the screw hole 31 when the bolt 4 rotates.
In order to further improve the installation firmness between the lower wheel structure and the door leaf profile, accommodating grooves 5 are formed between both ends of the pulley block 2 and the shell 1, and the locking pieces 3 are accommodated in the two accommodating grooves 5.
The implementation principle of the first embodiment is as follows: in the assembling process of lower round of structure, settle locking plate 3 at the tank bottom in the joint groove of door leaf section bar earlier, then rotate bolt 4, and then drive locking plate 3 rebound, both ends in locking plate 3 all stretch out to when inconsistent with the lateral wall of locking groove 6, contact block 7 also inconsistent with the cell wall of storage tank 5, at this moment, the long limit direction of locking plate 3 is perpendicular with the long limit direction dislocation of shell 1, continue to rotate bolt 4, make locking plate 3 and the inseparable block in joint groove of door leaf section bar, the whole assembly of structure of accomplishing down round.
Example two:
as shown in fig. 6, the difference from the first embodiment is that the driving member includes a fixing plate 8, a bolt 4 and a rotating ring, the fixing plate 8 is disposed at the top of the housing 1, a screw hole 31 is formed in the middle of the surface of the locking piece 3, the bolt 4 is screwed into the screw hole 31, and the tail of the bolt 4 passes through the fixing plate 8 and is coaxially and fixedly disposed with the rotating ring 10.
In the second embodiment, one end of the elastic element abuts against the head of the bolt 4, and the other end abuts against the locking piece 3.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
