Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a clamping assembly for a transmission belt, which can securely confine the transmission belt within the clamping seat.
[0004] This utility model discloses a belt clamping assembly for clamping a belt and linking two frames together. It includes a clamping base with a clamping cavity. The inner walls on both sides of the clamping cavity are respectively provided with grooves that match the outer teeth of the belt. The top and right ends of the clamping cavity are provided with slots for the belt to enter. A locking element is installed on the slot at the top of the clamping cavity to prevent the belt from detaching from the clamping base.
[0005] As a further improvement of this utility model, one or more connecting shafts are fixedly provided at the bottom of the clamping seat, and rollers are rotatably sleeved on the outer circumference of the connecting shafts; the rollers are used to roll and are embedded in the rolling groove provided at the top of the frame.
[0006] As a further improvement of this utility model, it also includes a mounting base and a connecting assembly; the clamping base is fixedly connected to the mounting base through the connecting assembly;
[0007] A support is fixedly installed at the bottom of the rear end of the mounting base.
[0008] As a further improvement of this utility model, the bottom of the mounting base is recessed and a mounting groove is provided; the mounting groove is inclined relative to the horizontal direction of the bottom end of the mounting base, that is, the groove is deeper at the rear end and shallower at the front end, the groove depth changes linearly, and the mounting groove is inclined relative to the bottom of the mounting base.
[0009] As a further improvement of this utility model, a fixing hole is provided on the rear side wall of the mounting base from the rear end to the front end. The fixing hole penetrates the inner side wall of the mounting groove and is connected to the inside of the mounting groove.
[0010] As a further improvement of this utility model, it also includes a locking device, which sequentially passes through the fixing hole and the mounting groove and is installed and connected to the fixing hole.
[0011] As a further improvement of this utility model, the connecting assembly includes a connector and a support column; the support column is fixedly disposed at the top of the rear end of the mounting base; the left end of the connector is fixedly disposed at the top of the support column, and the right end of the connector is fixedly connected to the left end of the clamping base.
[0012] As a further improvement of this utility model, the clamping seat includes a first clamping plate and a second clamping plate; the first clamping plate and the second clamping plate are arranged opposite to each other to form a clamping cavity; a base is fixedly provided at the bottom of the two clamping plates to support the transmission belt and restrict the downward movement of the transmission belt.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. Bidirectional limiting and reliable anti-disengagement: The toothed grooves on both sides of the clamping cavity cooperate with the top locking part to restrict the transmission belt in the clamping cavity, realizing bidirectional limiting of the transmission belt in both the up and down and left and right directions;
[0017] The top locking element can adjust the clamping force through the locking screw thread, further preventing the drive belt from coming off the clamping seat under long-term vibration or load fluctuation, and facilitating maintenance;
[0018] 2. The bottom of the clamping seat is equipped with rollers that are rolled and embedded in the rolling groove at the top of the frame, so as to realize the smooth rolling of the transmission belt during horizontal linkage; the sliding friction between the rollers and the rolling groove is reduced, which not only ensures smooth linkage, but also reduces wear on the tooth surface of the transmission belt and extends the service life of the transmission belt.
[0019] 3. The bottom of the mounting base is recessed and has an installation groove that is inclined relative to the horizontal direction of the bottom of the mounting base. When the fastener is installed, the installation groove protrudes from the bottom of the mounting base and abuts against the frame, thereby fixing the mounting base to the top of the frame. The depth of the inclined groove decreases linearly from the rear end to the front end. After the fastener passes through the fixing hole on the rear side wall, it can be accurately locked in place under linear guidance, simplifying the installation operation.

The aforementioned orientations or positional relationships are based on the attached... Figure 3 The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0031] Specific Implementation Example 1: Please refer to Figure 1-7 A belt clamping assembly 3 is used to link two frames 1 together. It includes a mounting base 31 for fixing on the frame 1 and a clamping base 32. The clamping base 32 is used to clamp the bent portion formed after the belt 2 is bent outward, so that the belt 2 forms a closed loop structure.
[0032] The clamping assembly 3 also includes a connecting assembly; the clamping base 32 is fixedly connected to the mounting base 31 via the connecting assembly; the connecting assembly includes a connector 33 and a support column 38; the support column 38 is fixedly disposed at the top of the rear end of the mounting base 31; the left end of the connector 33 is fixedly disposed at the top of the support column 38, and the right end of the connector 33 is fixedly connected to the left end of the clamping base 32.
[0033] The clamping seat 32 has a clamping cavity 323; the inner sidewalls on both sides of the clamping cavity 323 are respectively provided with grooves 324 that match the outer teeth of the transmission belt 2, and the top and right ends of the clamping cavity 323 are provided with slots for the transmission belt 2 to enter. A locking member 35 is installed on the slot at the top of the clamping cavity 323 to prevent the transmission belt 2 from disengaging from the clamping seat 32.
[0034] When the transmission belt 2 is inserted into the clamping cavity 323 from top to bottom through the slot of the clamping seat 32, the outer teeth of the transmission belt 2 are embedded in the groove 324 in the corresponding clamping cavity 323, thereby restricting the horizontal movement of the transmission belt 2.
[0035] Furthermore, the clamping seat 32 includes a first clamping plate 321 and a second clamping plate 322; the first clamping plate 321 and the second clamping plate 322 are arranged opposite to each other to form a clamping cavity 323; a base is fixedly provided at the bottom of the two clamping plates to support the transmission belt 2 and restrict the transmission belt 2 from moving downward.
[0036] The upper ends of the first clamping plate 321 and the second clamping plate 322 are respectively provided with corresponding locking holes 325; the locking holes 325 extend from the outer side wall of the clamping plate into the clamping cavity 323.
[0037] Preferably, when the drive belt 2 is inserted into the clamping cavity 323, the locking hole 325 is located at the top of the drive belt 2.
[0038] The locking member 35 passes through the two locking holes 325 in sequence and is threadedly connected to the clamping plate to confine the transmission belt 2 within the clamping cavity 323, thereby restricting the vertical movement of the transmission belt 2 and thus fixing the transmission belt 2.
[0039] The locking member 35 is provided with threads around its outer periphery, and the inner wall of the locking hole 325 is provided with threads that match the threads of the locking member 35.
[0040] A connecting shaft 37 is fixedly installed at the bottom of the base of the clamping seat 32, and a roller 36 is rotatably sleeved on the outer circumference of the connecting shaft 37; the roller 36 is used to roll and embed in the rolling groove provided at the top of the frame 1 so that the relative movement of the frame 1 is smoother.
[0041] A support is fixedly installed at the bottom of the rear end of the mounting base 31.
[0042] The mounting base 31 has a recessed mounting groove 311 at its bottom. The mounting groove 311 is inclined relative to the horizontal direction of the bottom of the mounting base 31, that is, the groove is deeper at the rear end and shallower at the front end, and the groove depth changes linearly. The mounting groove 311 is inclined relative to the bottom of the mounting base 31.
[0043] Optionally, the front end of the mounting slot 311 extends through the front side wall of the mounting base 31.
[0044] The mounting base 31 has a fixing hole on its rear side wall from the rear end to the front end. The fixing hole passes through the inner side wall of the mounting groove 311 and is connected to the inside of the mounting groove 311.
[0045] The clamping assembly 3 also includes a locking member 34, which passes through the fixing hole and the mounting groove 311 in sequence and is connected to the fixing hole for installation.
[0046] The inner wall of the fixing hole is provided with threads, and the outer periphery of the locking member 34 is provided with threads that match the threads on the inner wall of the fixing hole. The locking member 34 is threadedly connected to the mounting base 31 through the fixing hole.
[0047] The bottom of the front end of the locking fastener 34 protrudes from the bottom of the mounting groove 311.
[0048] Working principle:
[0049] When the frame 1 has three panels, pulleys 4 are provided at both ends of the top of the frame 1, and the transmission belt 2 is wrapped around the outside of the corresponding pulleys 4 at both ends of the top of the same frame 1 and tensioned.
[0050] Two clamping components 3 are provided at one end of the frame 1 near the middle frame 1. The two clamping components 3 are arranged in opposite directions and side by side. The two clamping components 3 are respectively mounted on the top of the two frames 1, and the two ends of the clamping components 3 are respectively installed on the corresponding frames 1 to link the two frames 1 together. The mounting base 31 of one of the clamping components 3 is embedded in the assembly groove provided on the top of one of the frames 1. The locking fastener 34 is used to adjust the fit between the mounting base 31 and the assembly groove to install the mounting base 31 in the assembly groove and avoid installation When seat 31 wobbles within the assembly slot, the roller 36 of clamping component 3 rolls within a rolling groove on the top of another frame 1. The mounting seat 31 and roller 36 of the other clamping component 3 are installed in opposite directions; that is, one clamping component 3 is fixedly connected to a corresponding frame 1, and the other clamping component 3 is fixedly connected to another frame 1. This arrangement ensures that the mounting seat 31 is flush against the side wall of the top end of the frame 1, allowing the roller 36 to move freely within the rolling groove on the top of the frame 1. Figure 2 The installation positions of the two clamping seats 32 are clearly visible;
[0051] Preferably, the rolling groove on the same frame 1 is disposed above the assembly groove, and the two are connected through each other; the mounting base 31 passes through the rolling groove and is embedded in the assembly groove;
[0052] Two clamping components 3 are also provided at the end of the frame 1 on the other side near the middle frame 1. These two clamping components 3 are also arranged in opposite directions and installed on the top of the two adjacent frames 1 to link the two frames 1 together. The installation method is the same as described above. Both sets of clamping components 3 are used to clamp the bent part formed after the transmission belt 2 is bent outward, so that the transmission belt 2 forms a closed loop structure on the side of the mounting base 31. When the frame 1 is provided with two, four or more frames 1, its assembly method is similar to that of the three-frame 1. Two clamping components 3 are installed at the same end of the adjacent frames. This will not be described in detail here.
[0053] With this installation setup, regardless of which frame 1 is slid, the transmission belt 2 rotates and moves, the frame 1 moves, and the clamping assembly 3 moves along with the transmission belt 2.
[0054] With this configuration, when the clamping cavity 323 clamps the bent portion of the transmission belt 2, the remaining portion of the transmission belt 2, excluding the bent portion, still forms a closed-loop structure. Furthermore, the clamping assembly 3 enables the two frames 1 to be installed and connected in a relatively movable manner. In addition, this fixing method eliminates the need for the pulley 4 to protrude from the frame 1, thereby improving the overall aesthetics of the frame 1.
[0055] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto; any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
