Description

Technical Field

[0001] This invention relates to the field of boxes, and more particularly to a snap-lock box. Background Technology

[0002] Square boxes are a commonly used type of packaging box (usually used to store various tools). In order to facilitate management and stacking of multiple boxes, patent publication document CN209064580U discloses a modular box assembly. This modular box assembly essentially uses flip-type locking clips to clamp and fix multiple boxes together. However, because the locking clips of this modular box assembly are set on the side wall of the box and there is no protective structure between the locking clips, it is very easy for the locking clips to disengage when foreign objects touch them during actual use, causing the locking clips to disengage and the two boxes that are locked together to separate. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a snap-on box.

[0004] The technical solution adopted in this invention is as follows:

[0005] A snap-fit ​​box includes a box body, on which a first end face, a second end face, and several side faces are provided. The first end face and the second end face are parallel to each other, and the side faces are located between the first end face and the second end face. The first end face is characterized by having a main clamping groove and a secondary clamping groove, and the second end face is characterized by having a secondary clamping hook for engaging with the secondary clamping groove.

[0006] A sliding groove is provided on the second end face of the box, and one opening of the sliding groove is located on the side of the box. A slider is slidably disposed in the sliding groove. A first spring is disposed in the sliding groove, with one end of the first spring abutting against the inner wall of the sliding groove and the other end of the first spring abutting against the slider. The first spring is in a taut state. A main clamping hook is disposed on the slider, which is used to cooperate with the main clamping groove. A limit block is disposed on the box, and a limit slide is disposed on the slider. The limit block and the limit slide are slidably engaged together.

[0007] In this type of snap-fit ​​box, a groove is provided on the second end face. One opening of the groove is located on the side of the box body, and a slider is slidably installed inside the groove. This effectively achieves a concealed installation of the slider, reducing the probability of the groove sliding due to contact with external objects.

[0008] In this type of snap-fit ​​box, a main clamping groove and a secondary clamping groove are provided on the first end face, while a secondary clamping hook is directly installed on the second end face. The main clamping hook is installed on a slider that can slide within a groove. This effectively achieves a sliding installation of the main clamping hook. Because a first spring is provided between the slider and the inner wall of the groove, the slider can automatically reset after being pressed. Therefore, when stacking this type of box, the secondary clamping hook first engages with the secondary clamping groove, and then the two boxes are completely pressed together, allowing the main clamping hook to slide in and engage within the main clamping groove. To separate the two boxes, the slider can be pressed to disengage the main clamping hook from the main clamping groove, thus separating the two boxes.

[0009] Similarly, in this type of box, the presence of the limiting block and the limiting slide rail limits the sliding amount of the slider, ensuring that the slider always slides within the slide groove.

[0010] Specifically, to ensure the stability of the slider during sliding, there are two limit slides, which are in a parallel state, and two limit blocks are set on the box to cooperate with the two limit slides.

[0011] Meanwhile, in order to ensure that the first spring can be stably held between the slider and the inner wall of the groove, a first countersunk hole is also provided on the slider, and one end of the first spring is located in the first countersunk hole.

[0012] In summary, this type of box has a groove on its body, and a slider is slidably installed in the groove. When two boxes are engaged together, the two boxes can be disengaged by pressing the slider in the groove. Furthermore, since the slider is located in the groove, the probability of the two boxes disengaging due to contact with external objects is reduced.

[0013] Optionally, it also includes a retaining plate, on which a pin is provided, and a pin hole is provided on the slider. The pin and the pin hole are rotatably engaged together. A second pin is provided between the slider and the retaining plate. A stepped groove is provided at the first end face of the housing for the retaining plate to engage. The first spring is perpendicular to the second spring.

[0014] The pin, pin hole, and second spring enable the elastic rotation of the clamping plate. When the main clamping hook is clamped in the main clamping groove, the clamping plate abuts against the stepped groove, ensuring the stability of the fit between the two boxes.

[0015] Specifically, for the sake of the stability of the second spring installation, a second countersunk hole is also provided on the slider, and one end of the second spring is located in the second countersunk hole.

[0016] Optionally, the housing is provided with a first sleeve post, the first spring is sleeved on the first sleeve post, and the abutment plate is provided with a second sleeve post, the second spring is sleeved on the second sleeve post.

[0017] Specifically, a portion of the first set of setting pillars is located inside the first countersunk hole, while a portion of the second set of setting pillars is located inside the second countersunk hole.

[0018] Specifically, both the first and second sets of columns are cylindrical.

[0019] Optionally, the slider is provided with a limiting groove, the abutting piece is provided with a limiting piece, and the limiting piece and the limiting groove are engaged together.

[0020] The function of the limiting groove and the limiting piece is to limit the rotation of the clamping piece. The two groove walls of the limiting groove are the limit positions of the movement of the limiting piece within the limiting groove. When the limiting piece rotates to contact the two limit positions of the limiting groove, it means that the clamping piece has rotated to the limit position.

[0021] Optionally, a guide post is provided in the slide groove of the housing, and a guide notch is provided on the slider. The guide post and the guide notch are slidably engaged together, and the guide post is parallel to the first spring.

[0022] The guide posts and guide notches slide together to ensure stable sliding of the slider and prevent it from deviating while sliding within the groove. There are two guide posts, both parallel to each other. The guide posts and guide notches are both T-shaped.

[0023] Optionally, a main guide slide and a secondary guide slide are provided at the first end face of the housing. The main guide slide is located at the main clamping groove, and the secondary guide slide is located at the secondary clamping groove.

[0024] The main guide rail facilitates the main clamping hook to slide into the main clamping slot, while the secondary guide rail facilitates the secondary clamping hook to slide into the secondary clamping slot.

[0025] Optionally, the main clamping hook is located outside the slide groove.

[0026] Optionally, the main clamping hook is L-shaped, and the secondary clamping hook is L-shaped.

[0027] Both the main clamping hook and the auxiliary clamping hook are L-shaped, which can achieve a stable clamping fit between the two boxes.

[0028] Optionally, the box body is a square box body.

[0029] The square box has four sides, which are perpendicular to the first end face and the second end face.

[0030] Optionally, a locking recess is provided on the first end face of the housing, and a locking protrusion is provided on the second end face of the housing.

[0031] Specifically, the function of the inner recess is to cooperate with the outer protrusion. The existence of the inner recess and the outer protrusion facilitates the docking of the two boxes during the fitting process.

[0032] The beneficial effects of this invention are: by opening a groove on the box and sliding the slider in the groove, when the two boxes are engaged together, the two boxes can be disengaged by pressing the slider in the groove. Furthermore, since the slider is located in the groove, the probability of the two boxes disengaging due to contact with external objects is reduced. Attached image description:

Detailed implementation method:

[0047] The present invention will now be described in detail with reference to the accompanying drawings.

[0048] As attached Figures 1-12 As shown, a snap-fit ​​box includes a box body with a first end face 101, a second end face, and several side faces 102. The first end face 101 and the second end face are parallel to each other, and the side faces 102 are located between the first end face 101 and the second end face. The first end face 101 is provided with a main clamping groove 108 and a secondary clamping groove 105, and the second end face is provided with a secondary clamping hook 1011, which is used to cooperate with the secondary clamping groove 105.

[0049] See appendix Figure 3 As shown, a groove 109 is provided on the second end face of the box body, and one opening of the groove 109 is located on the side 102 of the box body. A slider 2 is slidably arranged in the groove 109. A first spring 401 is provided in the groove 109. One end of the first spring 401 abuts against the inner wall of the groove 109, and the other end of the first spring 401 abuts against the slider 2. The first spring 401 is in a taut state. A main clamping hook 201 is provided on the slider 2. The main clamping hook 201 is used to cooperate with the main clamping groove 108. A limit block 1012 is provided on the box body, and a limit slide 202 is provided on the slider 2. The limit block 1012 and the limit slide 202 are slidably engaged together.

[0050] See appendix Figure 4As shown, in this type of snap-fit ​​box, since a groove 109 is opened at the second end face, one opening of the groove 109 is located at the side 102 of the box body, and a slider 2 is slidably arranged in the groove 109, it is equivalent to achieving a concealed installation of the slider 2, reducing the probability of the groove 109 sliding due to contact with external objects.

[0051] In this type of snap-fit ​​box, a main clamping groove 108 and a secondary clamping groove 105 are provided at the first end face 101, while a secondary clamping hook 1011 is directly installed at the second end face. The main clamping hook 201 is installed on a slider 2 that can slide within a sliding groove 109. This effectively achieves a sliding installation of the main clamping hook 201. Since a first spring 401 is provided between the slider 2 and the inner wall of the sliding groove 109, the slider 2 can automatically reset after being pressed. Therefore, when stacking this type of box, the secondary clamping hook 1011 is first clamped together with the secondary clamping groove 105, and then the two boxes are completely pressed together, allowing the main clamping hook 201 to slide in and clamp within the main clamping groove 108. To separate the two boxes, the slider 2 can be pressed to disengage the main clamping hook 201 from the main clamping groove 108, thus separating the two boxes.

[0052] Similarly, in this type of box, the presence of the limiting block 1012 and the limiting slide 202 limits the sliding amount of the slider 2, ensuring that the slider 2 always slides within the slide groove 109.

[0053] See appendix Figure 5 As shown, in order to ensure the stability of the slider 2 when it slides, there are two limit slides 202. The two limit slides 202 are in a parallel state, and two limit blocks 1012 are set on the box for the two limit slides 202 to cooperate.

[0054] Meanwhile, in order to ensure that the first spring 401 can be stably held between the slider 2 and the inner wall of the groove 109, a first countersunk hole 205 is also provided on the slider 2, and one end of the first spring 401 is located in the first countersunk hole 205.

[0055] In summary, this type of box has a groove 109 on the box body and a slider 2 is slidably installed in the groove 109. When the two boxes are engaged together, the two boxes can be disengaged by pressing the slider 2 in the groove 109. Furthermore, since the slider 2 is located in the groove 109, the probability of the two boxes disengaging due to contact with external objects is reduced.

[0056] As attached Figure 10 , 12As shown in Figure 13, it also includes a retaining plate 3, on which a pin 301 is provided, and a pin hole 204 is provided on the slider 2. The pin 301 and the pin hole 204 are rotatably engaged together. A second pin 301 is provided between the slider 2 and the retaining plate 3. A stepped groove is provided at the first end face 101 of the housing. The stepped groove is used for the retaining plate 3 to engage. The first spring 401 is perpendicular to the second spring 402.

[0057] The pin 301, pin hole 204 and second spring 402 are used to realize the elastic rotation installation of the clamping piece 3. When the main clamping hook 201 is clamped in the main clamping groove 108, the clamping piece 3 abuts against the stepped groove to ensure the stability of the fit between the two boxes.

[0058] Specifically, for the installation stability of the second spring 402, a second countersunk hole 206 is also provided on the slider 2, and one end of the second spring 402 is located in the second countersunk hole 206.

[0059] As attached Figure 6 and 7 As shown, a first sleeve post 1014 is provided on the box body, a first spring 401 is sleeved on the first sleeve post 1014, a second sleeve post 303 is provided on the abutment plate 3, and a second spring 402 is sleeved on the second sleeve post 303.

[0060] Specifically, a portion of the first set of setting post 1014 is located inside the first countersunk hole 205, while a portion of the second set of setting post 303 is located inside the second countersunk hole 206.

[0061] Specifically, both the first set of columns 1014 and the second set of columns 303 are cylindrical.

[0062] As attached Figure 10 , 11 As shown in Figure 12, a limiting groove 207 is provided on the slider 2, and a limiting piece 302 is provided on the abutting piece 3. The limiting piece 302 and the limiting groove 207 are engaged together.

[0063] The function of the limiting groove 207 and the limiting piece 302 is to limit the rotation of the clamping piece 3. The two groove walls of the limiting groove 207 are the limit positions of the movement of the limiting piece 302 within the limiting groove 207. When the limiting piece 302 rotates to contact the two limit positions of the limiting groove 207, it means that the clamping piece 3 has rotated to the limit position.

[0064] As attached Figure 6 As shown in Figure 7, a guide post 1013 is provided in the slide groove 109 of the box body, and a guide notch 203 is provided on the slider 2. The guide post 1013 and the guide notch 203 are slidably engaged together, and the guide post 1013 is parallel to the first spring 401.

[0065] The guide post 1013 and the guide notch 203 are slidably engaged. This engagement ensures the slider 2 can slide stably, preventing it from deviating while sliding within the groove 109. Specifically, there are two guide posts 1013, which are parallel to each other. Both the guide posts 1013 and the guide notch 203 are T-shaped.

[0066] As attached Figure 2 As shown in Figure 3, a main guide slide 107 and a secondary guide slide 104 are provided at the first end face 101 of the housing. The main guide slide 107 is located at the main clamping groove 108, and the secondary guide slide 104 is located at the secondary clamping groove 105.

[0067] The main guide slide 107 facilitates the main clamping hook 201 to slide into the main clamping groove 108, and the secondary guide slide 104 facilitates the secondary clamping hook 1011 to slide into the secondary clamping groove 105.

[0068] As attached Figure 5 As shown, the main clamping hook 201 is located outside the slide groove 109.

[0069] As attached Figure 2 As shown in Figure 3, the main clamping hook 201 is L-shaped, and the secondary clamping hook 1011 is L-shaped.

[0070] Both the main clamping hook 201 and the auxiliary clamping hook 1011 are L-shaped, which can achieve a stable clamping fit between the two boxes.

[0071] As attached Figure 1 As shown in Figure 9, the box is a square box.

[0072] The square box has four sides 102, which are perpendicular to the first end face 101 and the second end face.

[0073] As attached Figure 1 As shown in Figure 3, a locking recess 106 is provided on the first end face 101 of the box body, and a locking protrusion 1010 is provided on the second end face of the box body.

[0074] Specifically, the function of the inner recess 106 is to cooperate with the outer protrusion 1010. The presence of the inner recess 106 and the outer protrusion 1010 facilitates the docking of the two boxes during the fitting process.

[0075] Combined with appendix Figures 8-10As shown, the usage of this type of box is explained in detail. When it is necessary to fix two boxes together, first, insert the secondary clamping hook 1011 on one box into the secondary clamping groove 105 on the other box. Then, press the two boxes together until they are close to each other. When the second end face of the upper box is flush with the first end face 101 of the lower box, the main clamping hook 201 on the upper box will engage with the main clamping groove 108 on the lower box. At the same time, the abutting piece 3 on the upper box slider 2 will engage with the stepped groove on the lower box, thus locking the two boxes together in both longitudinal and transverse directions. To disengage the two boxes, press the slider 2 to the left, causing it to slide to the left. This disengages the main clamping hook 201 from the main clamping groove 108, and the abutting piece 3 slides out of the stepped groove. The two boxes can then be separated.

[0076] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent modifications made based on the content of the present invention specification, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
