Description

Technical Field

[0001] This utility model relates to the field of linear transmission module technology, and in particular to a cover belt fixing device for linear transmission modules. Background Technology

[0002] The linear module disclosed in TW I592249 uses a fixing piece at each end of the dustproof strip, and each fixing piece is secured by multiple screws inserted into screw holes in the housing. However, in the aforementioned patent case, the fixing pieces are completely exposed above the dustproof strip, making it possible for the fixing pieces to fall off due to improper impact, thereby affecting the sealing performance of the dustproof strip.

[0003] The linear actuator disclosed in TW I709701 has an upper cover above the adjustment block, which is used to press down the adjustment end of the dustproof belt. However, in the aforementioned patent case, the upper cover is completely exposed above the dustproof belt, which makes it possible for the upper cover to fall off due to improper impact, thereby affecting the sealing performance of the dustproof belt. Utility Model Content

[0004] The main purpose of this utility model is to provide a cover belt fixing device for linear transmission modules, which can effectively prevent the sealing performance of the cover belt from being affected by improper collisions caused by external forces, and effectively utilize the internal space of the bearing seat.

[0005] To achieve the aforementioned main objectives, the cover strip fixing device provided by this utility model includes a bearing seat, a pressure plate, and a fixing member. The bearing seat is disposed at one end of a base and has a receiving groove and a fixing hole communicating with the receiving groove, wherein one end of a cover strip extends into the receiving groove; the pressure plate is disposed in the receiving groove of the bearing seat and is located above the cover strip; the fixing member is disposed in the fixing hole of the bearing seat and presses against the pressure plate, so that the pressure plate tightly fixes the cover strip to the bearing seat.

[0006] As can be seen from the above, the cover strip fixing device provided by this utility model hides the pressure plate in the receiving groove of the bearing seat, which can effectively prevent the pressure plate from falling off due to improper external force collision, keep the cover strip in good sealing condition, and effectively utilize the internal space of the bearing seat.

[0007] In an embodiment of this utility model, the pressure plate has a through hole that connects to the fixing hole of the bearing seat. The fixing member has a tapered end that passes through the through hole of the pressure plate. This allows the pressure plate to achieve automatic alignment and downward clamping.

[0008] In an embodiment of this utility model, the pressure plate has two perforations, the distance between the perforations is defined as d, and the length of the pressure plate is defined as L. d and L satisfy the following relationship: d / L = 60%~80%. In this way, the pressure plate can be subjected to more uniform force.

[0009] In an embodiment of this utility model, the width of the receiving groove is defined as W1, the height of the receiving groove is defined as H, and the thickness of the pressure plate is defined as T. The three satisfy the following relationship: W1 / L = 101%~102% and H / T = 110%~120%. Through the above relationship, the receiving groove can be used with pressure plates of different specifications.

[0010] In an embodiment of this utility model, the depth of the receiving groove is defined as D, and the width of the pressure plate is defined as W2, and the two satisfy the following relationship: D≧W2. This relationship ensures that the pressure plate is hidden within the receiving groove and not exposed.

[0011] In an embodiment of this utility model, the fastener is screwed into the fixing hole of the bearing seat, making it convenient to lock and remove the fastener.

[0038] The applicant hereby clarifies that throughout this specification, including the embodiments described below and the claims of the patent application, all directional terms are based on the directions shown in the accompanying drawings. Secondly, in the embodiments and drawings described below, the same reference numerals represent the same or similar elements or structural features thereof.

[0039] like Figure 1 The linear drive module 1 shown includes a base 2, a slide 3 and a cover belt 4. A timing belt (not shown) is installed inside the base 2. The slide 3 is located above the base 2 and connected to the timing belt, so that the slide 3 can be driven by the timing belt to move back and forth relative to the base 2. The cover belt 4 is located above the base 2 and passes through the slide 3 to provide a dustproof effect for the components (such as the timing belt) inside the base 2.

[0040] like Figure 1 and Figure 2As shown, the cover belt fixing device 10 provided by this utility model is set at two opposite ends of the base 2 and includes a bearing seat 20, a pressure plate 30, and two fixing members 40 (in fact, only at least one is needed).

[0041] The bearing housing 20 is assembled at one end of the base 2. A timing pulley 5 is installed inside the bearing housing 20. One of the timing pulleys 5 is connected to a drive source (e.g., a motor, not shown in the figure). When the drive source drives the timing pulley 5 connected to it to rotate, the driven timing pulley 5 will drive the other timing pulley 5 to rotate via the timing belt. At this time, the slide 3 can be synchronously moved back and forth relative to the base 2. Figure 2 As shown, the bearing housing 20 has a receiving groove 22 with an opening facing the base 2. The receiving groove 22 is used for one end of the covering strip 4 to pass through. The bearing housing 20 has two fixing holes 24 above the receiving groove 22 that communicate with the receiving groove 22 (here, screw holes are used as an example, but in reality, only one is needed).

[0042] like Figures 2 to 4 As shown, the pressure plate 30 is disposed in the receiving groove 22 of the bearing housing 20 and located above the cover strip 4. The pressure plate 30 has two through holes 32 (in fact, only at least one is needed), and the two through holes 32 of the pressure plate 30 are connected to the two fixing holes 24 of the bearing housing 20.

[0043] In this embodiment, the fastener 40 is exemplified by a headless screw. Figure 3 and Figure 4 As shown, the fastener 40 is screwed into the fixing hole 24 of the bearing seat 20, and the fastener 40 has a tapered end 42. The tapered end 42 of the fastener 40 passes through the through hole 32 of the pressure plate 30, which on the one hand allows the pressure plate 30 to achieve the effect of automatic alignment, and on the other hand applies downward pressure to the pressure plate 30, so that the pressure plate 30 tightly fixes the covering strip 4 to the bearing seat 20.

[0044] It is worth mentioning that, such as Figure 2 As shown, the distance between the two perforations 32 is d, and the length of the pressure plate 30 is L. d and L satisfy the following relationship: d / L = 60%~80%. If d / L < 60%, the distance between the two perforations 32 is too close, resulting in uneven force on the pressure plate 30, which in turn prevents the cover strip 4 from maintaining a good sealing effect. If d / L > 80%, the two perforations 32 will be too close to the edge, making it easy for the pressure plate 30 to break during the processing of the perforations 32. In other words, when d and L satisfy the above relationship, after the two fasteners 40 are locked, the pressure plate 30 can be subjected to more even force, thus allowing the cover strip 4 to maintain a good sealing effect.

[0045] like Figure 3As shown, the width of the receiving groove 22 is W1, the height of the receiving groove 22 is H, and the thickness of the pressure plate 30 is T. These three satisfy the following relationship: W1 / L = 101%~102% and H / T = 110%~120%. Based on this relationship, the receiving groove 22 can be used with pressure plates 30 of different specifications. Furthermore, as... Figure 4 As shown, the depth of the receiving groove 22 is D, and the width of the pressure plate 30 is W2. The two satisfy the following relationship: D≧W2. Through the above relationship, it can be ensured that the pressure plate 30 is hidden in the receiving groove 22 and is not exposed.

[0046] In summary, the cover belt fixing device 10 provided by this utility model hides the pressure plate 30 in the receiving groove 22 of the bearing seat 20, which can effectively prevent the pressure plate 30 from falling off due to improper collision with external force, and keep the cover belt 4 in good sealing condition.

[0047] The above description is merely an optional embodiment of this utility model and should not be construed as limiting the scope of the embodiments of this utility model; that is, any equivalent changes and modifications made in accordance with the claims of this utility model should still fall within the scope of this utility model patent.

[0048] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
