[0008] Referring to Figures 1 to 5 and 7, the figures show embodiments of a fastener having a material supply port of the present invention, however, these embodiments are used for illustration purposes only and the claims are not intended to be limited to these structures.

[0009] (Embodiment 1) As shown in Figs. 1 to 5, a fastener 01 having such a material supply port is used to fasten and connect one slider block 03 and two return structures 04 in a cross roller type linear slide rail 02. The slider block 03 has a through groove 032 formed along the axial direction, so that a rail (not shown in the figure) slides through the slider block 03. The return structures 04 are provided at both ends of the slider block 03, and two passages (not shown in the figure) are formed on both sides of the through groove 032, so that a plurality of rollers (not shown in the figure) are inserted into the passages. The passage extends to each of the reflux structures 04 and is formed in a loop, and each of the passages is formed so as not to intersect and communicate with the inside of the reflux structure 04. A reflux section (not shown in the figure) is formed inside the reflux structure 04 of the passage, and each of the reflux structures 04 is provided with a through hole 042, which communicates with the reflux section, so that the roller is placed in the passage by passing through the through hole 042. The reflux structure 04 has a first side (not shown in the figure) and a second side 044, and the first side faces the second side 044 and is adjacent to the slider block 03.

[0010] The locking device 01 includes a first blocking plate 10, a second blocking plate 20, and a connecting bar 30, of which one end of the connecting bar 30 is integrally joined to the first blocking plate 10, and the other end of the connecting bar 30 is integrally joined to the second blocking plate 20. The first blocking plate 10 and the second blocking plate 20 are adjacent to each other on the second side 044, and the first blocking plate 10 and the second blocking plate 20 are adjacent to each other in the lateral direction of the reflux section, thereby locking and connecting the slider block 03 and each of the reflux structures 04, and increasing the bonding strength between the reflux structure 04 and the slider block 03.

[0011] A first material supply port 40 is formed in the first blocking plate 10, and a second material supply port 50 is formed in the second blocking plate 20, so that the roller passes through the first material supply port 40 and the second material supply port 50 and enters each of the passages.

[0012] According to the above-mentioned structural assembly form and technical features, the first blocking plate 10 and the second blocking plate 20 relatively restrict the slider block 03 and each of the return structures 04, thereby locking and connecting the slider block 03 and each of the return structures 04, the slider block 03 and each of the return structures 04 are restricted and positioned between the first blocking plate 10 and the second blocking plate 20, and the first blocking plate 10 and the second blocking plate 20 are respectively adjacent to the lateral direction of the return section, and when the roller is moved in the passage and passes through the return section, the roller forms a sharp turn in the return section, and the roller is moved toward the return structure 04. A relative acting force is formed against the slider block 03, the strength of which is F, and the speed of the relative movement between the slider block 03 and the rail is V. F is positively correlated with V, and the first and second blocking plates 10 and 20 are located toward the upward direction of this acting force, and the first and second blocking plates 10 and 20 respectively provide support for each of the return structures 04, thereby increasing the connection strength between the return structure 04 and the slider block 03, and thereby improving the speed limit of the relative movement between the slider block 03 and the rail, provided that an effective connection between the slider block 03 and each of the return structures 04 is maintained.

[0013] The linear slide rail 02 may further include two sealing covers 06, each of which is adjacent to the corresponding return structure 04, and the first blocking plate 10 and the second blocking plate 20 are positioned between the return structure 04 and the sealing cover 06, and each of the sealing covers 06 has two insert blocks 062 protruding therefrom in accordance with each of the through holes 042, and each of the insert blocks 062 passes through the corresponding first material supply port 40 and second material supply port 50 and is inserted into each of the through holes 042, thereby sealing the through holes 042. The sealing cover 06 may have a scratch brush structure having an oil scraping effect.

[0014] The connecting bar 30 passes through the slider block 03 and is adjacent to one side of the through-groove 032. The connecting bar 30 is formed with a first blade piece 31 and a second blade piece 32. The first blade piece 31 and the second blade piece 32 are arranged symmetrically with each other and form an included angle of 90 degrees between the first blade piece 31 and the second blade piece 32. The connecting bar 30 further has a connecting piece 33, and both sides of the connecting piece 33 are integrally joined to the first blade piece 31 and the second blade piece 32, respectively.

[0015] An arc-shaped first blocking edge 34 is provided at the end of the first blade piece 31, and the first blocking edge 34 extends in a direction away from the second blade piece 32, and an arc-shaped second blocking edge 35 is provided at the end of the second blade piece 32, and the second blocking edge 35 extends in a direction away from the first blade piece 31, and when the roller runs in the passage and passes through one side of the through groove 032, the first blocking edge 34 and the second blocking edge 35 each form an engaging stop with one end of the roller facing the through groove 032.

[0016] In this embodiment, the roller is a cylindrical body, and the axial cross section of the through groove 032 that is aligned with the roller is an elongated rectangular hole, and the first material supply port 40 and the second material supply port 50 are each an elongated rectangular hole, so that the roller passes through the first material supply port 40 and the second material supply port 50 and enters each of the passages, and the width of the first material supply port 40 and the second material supply port 50 in the longitudinal direction is larger than the through groove 032, and the first material supply port 40 has two first short sides 42, and the first short sides 42 face each other. The first blocking edge 34 is defined as being arranged facing each other, and the two first imaginary lines 44 extend along the tangential direction of each of the first short sides 42, and the orthogonal projection of the first blocking edge 34 in the direction toward the first blocking plate 10 is located between the first imaginary lines 44, the second material supply port 50 has two second short sides 52, and the second short sides 52 are arranged facing each other, and the two second imaginary lines 54 extend along the tangential direction of each of the second short sides 52, and the orthogonal projection of the second blocking edge 35 in the direction toward the second blocking plate 20 is located between the second imaginary lines 54. As a result, the distance between the first short sides 42 of the first material supply port 40 is greater than the width of the corresponding through hole 042 in the longitudinal direction, and the distance between the second short sides 52 of the second material supply port 50 is also greater than the width of the corresponding through hole 042 in the longitudinal direction.

[0017] As shown in FIG. 2 and FIG. 6, the insert block 062 is configured by integrally joining a sealing prevention part 063 and a tightly fitted closing part 064 to each other in accordance with the relative spatial configuration of the first material supply port 40, the second material supply port 50, and the corresponding through hole 042, and the sealing prevention part 063 is joined to the sealing lid 06, and the sealing prevention part 063 is located between the sealing lid 06 and the tightly fitted closing part 064, and the tightly fitted closing part 064 is connected to the corresponding through hole 042. The sealing prevention portion 063 is an elongated rectangular block body corresponding to the first material supply port 40 and the second material supply port 50, and two attachment surfaces 065 are formed on one side of the sealing prevention portion 063 facing the return structure 04, and each attachment surface 065 is adjacent to both ends of the tightly fitting closing portion 064 in the longitudinal direction, and an end surface 066 is formed on one side of the tightly fitting closing portion 064 away from the sealing lid 06.

[0018] When the sealing cover 06 is installed, the tight-fitting blocking portion 064 passes through the fastener 01 and enters the corresponding through hole 042, and sufficiently fills the through hole 042 to tightly fit and block it. The sealing preventing portion 063 is located at the corresponding first material supply port 40 or the second material supply port 50, and the attachment surface 065 is attached to the reflux structure 04. The length between the attachment surface 065 and the end face 066 of the tight-fitting blocking portion 064 is the same as the length of the through hole 042, thereby forming a state in which the end face 066 is exactly aligned and aligned with the outer end of the reflux section. By storing the corresponding sealing preventing portion 063 in the first material supply port 40 and the second material supply port 50, respectively, the sealing preventing portion 063 can reliably block and seal the outer end of the through hole 042.

[0019] (Embodiment 2) As shown in FIG. 7, the second embodiment is mainly different from the first embodiment in that when the roller is spherical, the first material supply port 40 and the second material supply port 50 are each configured as a circular hole. [Explanation of symbols]
