The first connecting piece comprises a first accommodating sleeve, the first accommodating sleeve is sleeved on a first cross rod extending along a second direction, the second direction is perpendicular to the first direction, a first limiting piece is fixedly connected with the first accommodating sleeve, a first mounting hole is formed in the first limiting piece in a penetrating mode, and the first mounting hole corresponds to the first fixing hole. The first fixing piece penetrates through the first mounting hole and the first fixing hole, so that the first connecting piece is fixed on the first mounting plate.

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, an embodiment of a first aspect of the present application provides a connecting fastener for assisting a worker in quickly connecting a first rail 7 and a second rail 8 to an upright 6. The connecting fastener comprises a sleeve 1, a first mounting plate 11, a second mounting plate 12, a first connecting piece 2 and a second connecting piece 3.

Wherein the sleeve 1 extends in a first direction Z, the sleeve 1 having a first bore 13 extending in the first direction Z. The upright 6 extending in the first direction Z is inserted into the first socket 13 so that the sleeve 1 is connected to the upright 6. The first mounting plate 11 and the second mounting plate 12 are spaced apart in the first direction Z and fixed to the outer side wall of the sleeve 1. The first connecting member 2 is connected to the first mounting plate 11, and the first connecting member 2 includes a first receiving sleeve 21, and the first receiving sleeve 21 has a second sleeve hole 211 extending along the second direction X. The first cross bar 7 extending in the second direction X is inserted into the second sleeve hole 211, so that the first cross bar 7 is connected with the first receiving sleeve 21, thereby connecting the first cross bar 7 with the vertical rod 6. The second connector 3 is connected to the second mounting plate 12, and the second connector 3 includes a second receiving sleeve 31, and the second receiving sleeve 31 has a third sleeve hole 311 extending along the third direction Y. The second cross bar 8 extending along the third direction Y is inserted into the third sleeve hole 311, so that the second cross bar 8 is connected with the second accommodating sleeve 31, thereby connecting the second cross bar 8 with the vertical rod 6.

Since the cross section of the outer wall of the cross bar used in the construction site is circular, the cross section of the inner wall of the first receiving sleeve 21 is correspondingly formed in a circular arc shape. When the first cross rod 7 is inserted into the first accommodating sleeve 21, the inner wall of the first accommodating sleeve 21 can be attached to the outer wall of the first cross rod 7, so that the first cross rod 7 is inserted into the first accommodating sleeve 21 more stably, and the first cross rod 7 is prevented from shaking. Similarly, the cross section of the inner wall of the second accommodating sleeve 31 is also correspondingly formed into a circular arc shape. When the second cross rod 8 is arranged in the second accommodating sleeve 31 in a penetrating manner, the inner wall of the second accommodating sleeve 31 can be attached to the outer wall of the second cross rod 8, so that the second cross rod 8 is prevented from shaking.

It can be understood that, as long as can make the inner wall of the accommodating sleeve laminate in the outer wall of the cross rod, avoid the cross rod from shaking, the inner walls of the first accommodating sleeve 21 and the second accommodating sleeve 31 can also be in other shapes, for example: when the cross-section of the outer wall of the first cross bar 7 and the second cross bar 8 is a quadrangle, the cross-section of the inner wall of the first receiving sleeve 21 and the second receiving sleeve 31 is a quadrangle.

Referring to fig. 2, 3 and 4, the first connecting member 2 further includes a first limiting piece 22, the first limiting piece 22 is fixedly connected to the first accommodating sleeve 21, and the first limiting piece 22 is used for limiting the first connecting member 2 to move in the first direction Z. The first limiting piece 22 has a first mounting hole 23, and the first mounting plate 11 has a first fixing hole 111 correspondingly. When the first connecting member 2 is installed, a worker firstly makes the first limiting piece 22 parallel to the first mounting plate 11, then the first limiting piece 22 is pressed against the upper surface of the first mounting plate 11, and the first mounting hole 23 is aligned with the first fixing hole 111. The first fixing piece 4 is inserted into the first mounting hole 23 and the first fixing hole 111 to fix the first connecting piece 2. First connecting piece 2 is through first mounting 4 fixed connection in first mounting panel 11, and the workman only needs to insert or extract first mounting 4, just can accomplish the dismouting of first connecting piece 2. Therefore, the first connecting member 2 can be easily and quickly connected to or disconnected from the first mounting plate 11.

In order to make the connection between the first connecting member 2 and the first mounting plate 11 more stable and reliable, the number of the first limiting pieces 22 of the first connecting member 2 is two. The two first limiting pieces 22 and the first accommodating sleeve 21 are both fixedly connected to the first accommodating sleeve 21, and the two first limiting pieces 22 are arranged at intervals along the first direction Z. When the worker fixes the first connecting member 2, firstly, the two first limiting pieces 22 are parallel to the first mounting plate 11, then the first mounting plate 11 is inserted between the two first limiting pieces 22, and the first mounting holes 23 on the two first limiting pieces 22 are aligned to the first fixing holes 111. The first fixing member 4 is inserted into the first mounting hole 23, the first fixing hole 111, and the first mounting hole 23 in order along the first direction Z to fix the first connecting member 2. Two first spacing pieces 22 can cooperate and press from both sides tight first mounting panel 11, and then can restrict the removal of first connecting piece 2 on first direction Z better, also can reduce rocking of first connecting piece 2 simultaneously.

Specifically, as shown in fig. 4, the cross section of the first connecting member 2 includes a first circular arc segment and two first straight line segments, and it can be seen that the two first straight line segments are respectively connected with two ends of the first circular arc segment. The first arc segment is a cross section of the first accommodating sleeve 21, and the two first straight segments are cross sections of the two first limiting pieces 22. When the first fixing member 4 is inserted into the first mounting hole 23, the first limiting piece 22 is pressed to elastically deform the first accommodating sleeve 21, so that the inner side wall of the first accommodating sleeve 21 compresses the first cross bar 7, and the first cross bar 7 is fixed in the first accommodating sleeve 21. When the first fixing member 4 is pulled out, the pressure applied to the first limiting piece 22 is removed, the first accommodating sleeve 21 is restored to the original state, and a worker can easily pull out the first cross bar 7.

In addition, the first fixing member 4 is provided with a first guide slope. By providing the first guide slope, the area of the cross section of the first fixing member 4 is made gradually smaller in the direction in which the first fixing member 4 is inserted into the first mounting hole 23. Specifically, the cross section of the end of the first fixing member 4 inserted into the first mounting hole 23 is smaller than that of the first mounting hole 23, so that a worker can conveniently insert the first fixing member 4 into the first mounting hole 23 and gradually reduce the gap between the first fixing member 4 and the inner wall of the first mounting hole 23 as the insertion depth of the first fixing member 4 increases. The cross-sectional area of the portion of the first fixing member 4 that has not been inserted into the first mounting hole 23 is larger than the first mounting hole 23, thereby preventing the first fixing member 4 from passing through the first mounting hole 23 by gravity.

In order to make the first fixing member 4 fit the first mounting hole 23 more tightly, a worker strikes the end of the first fixing member 4 having a larger cross-sectional area with a tool to apply an impact force to the first fixing member 4 in the same direction as the insertion direction of the first fixing member 4, so that a larger frictional force is generated between the first fixing member 4 and the first mounting hole 23, and thus the first fixing member 4 is not easily detached. Similarly, in order to remove the first fixing member 4, a worker strikes the insertion end of the first fixing member 4 with a tool to apply a force to the first fixing member 4 opposite to the insertion direction, so that the first fixing member 4 is loosened, thereby removing the first fixing member 4.

It is easy to understand that, since the first fixing member 4 is often subjected to an impact force, the impact force is transmitted to the first limiting piece 22 and the first mounting plate 11, which may cause the first mounting hole 23 and the first fixing hole 111 to deform, thereby affecting the use of the connecting fastener. Two first fixed orificess 111 have been seted up on first mounting panel 11, can reduce the influence of the local deflection in the connection fastener use, increase this connection fastener's repeatedly usable's number of times. The two first fixing holes 111 are respectively located at two sides of the sleeve 1, and the two first fixing holes 111 are arranged at intervals along the third direction Y. When one of the first fixing holes 111 is deformed, the worker can also install the first connecting member 2 through the other first fixing hole 111.

Referring to fig. 2, 3 and 5, similar to the first connecting member 2, the second connecting member 3 further includes a second limiting piece 32, the second limiting piece 32 is fixedly connected to the second accommodating sleeve 31, and the second limiting piece 32 is used for limiting the second connecting member 3 to move in the first direction Z. The second accommodating sleeve 31 is matched with the second connecting piece 3, so that the second cross rod 8 and the sleeve 1 are fixed relatively. The second limiting piece 32 is provided with a second mounting hole 33, and the second mounting plate 12 is correspondingly provided with a second fixing hole 121. When installing the second connecting member 3, the worker first attaches the second limiting piece 32 to the upper surface of the second mounting plate 12, aligns the second mounting hole 33 with the second fixing hole 121, and then inserts the second fixing member 5 into the second mounting hole 33 and the second fixing hole 121 to fix the second connecting member 3. The second connecting piece 3 is fixedly connected to the second mounting plate 12 through the second fixing piece 5, and a worker only needs to insert or pull out the second fixing piece 5 to complete the dismounting of the second connecting piece 3. Therefore, the second connecting member 3 can be easily and quickly connected to or disconnected from the second mounting plate 12.

In order to make the connection between the second connecting member 3 and the second mounting plate 12 more stable and reliable, the number of the second limiting pieces 32 of the second connecting member 3 is also two. The two second limiting pieces 32 and the second accommodating sleeve 31 are both fixedly connected to the second accommodating sleeve 31, and the two second limiting pieces 32 are arranged at intervals along the first direction Z. When the second connecting member 3 is fixed, the second mounting holes 33 of the two second limiting pieces 32 are aligned to the second fixing holes 121. The second fixing member 5 is inserted into the second mounting hole 33, the second fixing hole 121, and the second mounting hole 33 in order along the first direction Z to fix the second connector 3. Two spacing pieces 32 of second can cooperate and press from both sides tight second mounting panel 12, and then can restrict the removal of second connecting piece 3 on first direction Z better to reduce rocking of second connecting piece 3.

Specifically, as shown in fig. 5, the cross section of the second connecting member 3 includes a second arc segment and two second straight segments, and it can be seen that the two second straight segments are respectively connected with two ends of the second arc segment. The second arc segment is a cross section of the second accommodating sleeve 31, and the two first straight segments are cross sections of the two second limiting pieces 32. When the second fixing member 5 is inserted into the second mounting hole 33, the second limiting piece 32 is pressed to elastically deform the second receiving sleeve 31, so that the inner sidewall of the second receiving sleeve 31 compresses the second cross bar 8, and the second cross bar 8 is fixed in the second receiving sleeve 31. When the second fixing member 5 is pulled out, the pressure applied to the second limiting piece 32 is removed, the second accommodating sleeve 31 is restored, and a worker can easily pull out the second cross bar 8.

In addition, the second fixing member 5 is provided with a second guide slope. By providing the second guide slope, the area of the cross section of the second fixing member 5 is made gradually smaller in the direction in which the second fixing member 5 is inserted into the second mounting hole 33. Specifically, the cross section of the end of the second fixing member 5 inserted into the second mounting hole 33 is smaller than that of the second mounting hole 33, so that a worker can conveniently insert the second fixing member 5 into the second mounting hole 33 and gradually reduce the gap between the second fixing member 5 and the inner wall of the second mounting hole 33 as the insertion depth of the second fixing member 5 increases. The cross-sectional area of the portion of the second fixing member 5 that has not been inserted into the second mounting hole 33 is larger than the second mounting hole 33, thereby preventing the second fixing member 5 from passing through the second mounting hole 33 by gravity.

In order to make the second fixing member 5 fit the second mounting hole 33 more tightly, a worker strikes the end of the second fixing member 5 having a larger cross-sectional area with a tool to apply an impact force to the second fixing member 5 in the same direction as the insertion direction of the second fixing member 5, so that a larger frictional force is generated between the second fixing member 5 and the second mounting hole 33, and the second fixing member 5 is not easily detached. In order to remove the second fixing member 5, a worker strikes the insertion end of the second fixing member 5 using a tool to apply a force to the second fixing member 5 opposite to the insertion direction, loosens the second fixing member 5, and thus removes the second fixing member 5.

It is easy to understand that, since the second fixing member 5 is often subjected to an impact force, the impact force is transmitted to the second limiting piece 32 and the second mounting plate 12, which may cause the second mounting hole 33 and the second fixing hole 121 to deform, thereby affecting the use of the connecting fastener. Two second fixing holes 121 are formed in the second mounting plate 12, so that the influence of local deformation of the connecting fastener in the using process can be reduced, and the number of times of repeated use of the connecting fastener is increased. The two second fixing holes 121 are respectively located at two sides of the sleeve 1, and the two second fixing holes 121 are arranged at intervals along the second direction X. When one of the second fixing holes 121 is deformed and cannot be used normally, a worker can install the second connecting member 3 through the other second fixing hole 121.

Referring to fig. 1 and 2, a supporting frame according to a second aspect of the present application includes the connecting fastener, a vertical rod 6, a first cross rod 7, and a second cross rod 8.

Wherein the upright 6 extends in a first direction Z. The pole setting 6 has been seted up locating hole 61, has been provided with locating pin 9 in the locating hole 61, and the pole setting 6 is located to the sleeve 1 cover of foretell connection fastener, and sleeve 1 receives the effect of gravity and supports and press in locating pin 9, and consequently, the position of connection fastener on first direction Z can be injectd to locating pin 9. The sleeve 1 of the connecting fastener is fixed with a first mounting plate 11 and a second mounting plate 12. The first mounting plate 11 is connected with a first connecting piece 2, the first connecting piece 2 is used for connecting a first cross rod 7, and the first cross rod 7 extends along the second direction X. The second mounting plate 12 is connected with a second connecting member 3, the second connecting member 3 is used for connecting a second cross bar 8, and the second cross bar 8 extends along the third direction Y. The upright 6 can be connected with a first cross bar 7 and a second cross bar 8 by connecting fasteners.

The height of the cross bar relative to the uprights 6 will also have different requirements in different applications. The vertical rod 6 is provided with a plurality of positioning holes 61 at intervals along the first direction Z, so that the height of the cross rod can be conveniently adjusted. The height of the connecting fastener can be adjusted by inserting the positioning pin 9 into the positioning holes 61 of different heights. Because first horizontal pole 7 and second horizontal pole 8 all are connected with pole setting 6 through connecting the fastener, consequently, through the height of adjustment connection fastener, just can adjust the height of first horizontal pole 7 and second horizontal pole 8.

The pole setting 6 cover of this support frame is equipped with sleeve 1, and sleeve 1 is fixed with first mounting panel 11 and second mounting panel 12. When a worker installs the first cross bar 7, the first cross bar 7 is first inserted into the first accommodating sleeve 21 of the first connecting member 2. The first connecting element 2 is then fixed to the first mounting plate 11 by means of the first fixing element 4, so that the first transverse bar 7 is fixedly connected to the upright 6. When the first cross rod 7 needs to be detached, the first connecting piece 2 and the first mounting plate 11 can be separated only by taking out the first fixing piece 4, so that the first cross rod 7 is taken out, and the operation is simple.

Similarly, when the worker installs the second cross rod 8, the second cross rod 8 is first inserted into the second receiving sleeve 31 of the second connecting member 3. The second connecting element 3 is then fixed to the second mounting plate 12 by means of the second fixing element 5, so that the second crosspiece 8 is fixedly connected to the upright 6. When the second cross bar 8 needs to be disassembled, the second connecting piece 3 and the second mounting plate 12 can be separated only by taking out the second fixing piece 5, so that the second cross bar 8 is taken out.

Therefore, this support frame easy dismounting and easy operation are favorable to improving the turnover rate of pole setting 6, first horizontal pole 7 and second horizontal pole 8.

In addition, other changes may be made by those skilled in the art within the spirit of the present application, and it is understood that such changes are encompassed within the scope of the present disclosure.
