Description

Technical Field

[0001] The utility model relates to the technical field of glass slides, and further relates to a glass slide fixing device. Background Art

[0002] At present, when fixing a glass slide, a fixing clamp is generally used. The operator adjusts the relative position and relationship between the fixing clamp and the glass slide by toggling the fixing clamp to fix or loosen the glass slide. However, this fixing method is more troublesome to operate, as the glass slide must be fixed while being supported. Moreover, when the fixing clamp is toggled, the fixing clamp may cause the glass slide to move, which may easily cause the position of the glass slide to shift, thereby causing the risk of the glass slide falling.

[0003] In summary, there is a need to improve the existing technology. Utility Model Content

[0004] In view of the above technical problems, the purpose of the utility model is to provide a glass slide fixing device, which can fix or remove the glass slide through simple operation without holding the glass slide during the process. The operation steps are simple and easy to use, and the glass slide will not shift during the installation and removal process.

[0005] In order to achieve the above object, the utility model provides a slide fixing device, comprising:

[0006] A base, wherein a receiving chamber adapted for a glass slide is formed on the base, and at least a portion of the receiving chamber is a hollow structure for preventing at least a portion of the glass slide from being blocked;

[0007] at least one fixing member, the fixing member is rotatably connected to the base, the fixing member and the accommodating chamber have a preset gap for accommodating the slide, and the fixing member has an adjustment portion so that the slide can be operated to switch between a first state and a second state,

[0008] In the first state, the glass slide is inserted into the preset gap and the adjusting portion is pressed, so that the fixing member rotates in the first movement direction to press the glass slide;

[0009] In the second state, the glass slide is released from the preset gap, and the adjusting portion is not pressed, so that the fixing member rotates in the second movement direction to remove the glass slide.

[0010] It is worth mentioning that the pressing or loosening of the fixing part on the glass slide is synchronously adjusted by the squeezing of the glass slide on the adjusting part, which can ensure the consistency of the position of the glass slide each time it is fixed. Moreover, this setting realizes the rapid assembly and disassembly of the glass slide, which has excellent practicality.

[0011] In some embodiments, the accommodating chamber has an insertion side and an abutting side, and the fixing member is disposed opposite to the accommodating chamber;

[0012] Among them, a side wall of the accommodating chamber passes through the corresponding edge of the base to form an insertion side of the accommodating chamber, the insertion side and the abutment side are arranged opposite to each other, and the adjustment part is located at one end of the fixing member close to the abutment side.

[0013] It can be understood that the two opposite sides of the accommodating chamber are respectively set as the insertion side and the abutment side. Therefore, when installing and removing the slide, the operator can insert or pull out the slide at the insertion side. The slide can slide along the accommodating chamber during the process, ensuring the reliability of the slide during movement.

[0014] In some embodiments, the fixing member is connected to the base via a rotating member, and the relative position of the rotating member is located between the insertion side and the abutment side, so that when the slide is switched between the first state and the second state, the fixing member rotates clockwise or counterclockwise.

[0015] The fixing member is connected to the base through a rotating member, so that when the glass slide presses the adjusting part, the fixing member rotates accordingly to press the glass slide to achieve fixation.

[0016] In some embodiments, an auxiliary fixing member is movably connected to the fixing member;

[0017] The auxiliary fixing member faces the accommodating chamber and can be operated to move toward or away from the accommodating chamber, thereby adjusting the relative distance between the end of the auxiliary fixing member and the accommodating chamber for fixing the slide.

[0018] It should be noted that the auxiliary fixing member can be displaced through manual operation of the operator, thereby achieving more precise adjustment of the fixation of the slide and being able to produce more diversified operations for different working conditions.

[0019] In some embodiments, the fixing member is further provided with a locking member that cooperates with the auxiliary fixing member, and a positioning groove is provided on the outer periphery of the auxiliary fixing member; the locking member passes through the fixing member,

[0020] In the first state, the locking member moves toward the direction close to the auxiliary fixing member to be engaged with the positioning groove, so as to limit the position of the auxiliary fixing member;

[0021] In the second state, the locking member moves in a direction away from the auxiliary fixing member, so that the locking member is disengaged from the positioning groove, so as to unlock the auxiliary fixing member.

[0022] Here, a locking member is provided to limit the auxiliary fixing member, thereby preventing the auxiliary fixing member from deviating and damaging the slide glass, and also preventing the auxiliary fixing member from accidentally falling off.

[0023] In some embodiments, a surface of the adjusting portion on one side close to the accommodating chamber is configured as an inclined end surface, and the inclined end surface faces away from the abutting side of the accommodating chamber, and is suitable for guiding the displacement of the slide.

[0024] It can be understood that by providing an inclined end surface on the adjustment part, a guide can be provided for the insertion of the slide, so that when the slide presses the adjustment part, it can be pushed to the abutment side along the trajectory of the inclined end surface, thereby completing the fixation of the slide.

[0025] In some embodiments, an elastic component is provided between the adjusting portion and the base.

[0026] In the first state, the elastic component is compressed to drive the adjustment portion to move away from the accommodating chamber;

[0027] In the second state, the elastic component is not compressed, thereby driving the adjustment part to reset.

[0028] It should be noted that the elastic component can provide elastic force for the movement of the fixing part, ensuring that the adjustment part can contract inward when under pressure to provide a accommodating position for the glass slide. When the glass slide is pulled out, the elastic component drives the adjustment part to reset, so that the device can return to its initial state to cope with subsequent work.

[0029] In some embodiments, the elastic component includes a spring and a fixed bracket, the fixed bracket is fixed to a side of the base having the accommodating chamber, the adjusting portion and the fixed bracket are fixed by the spring, and the spring is used to provide elastic force.

[0030] In some embodiments, the number of the fixing members is two, and the two fixing members are symmetrically distributed along the length direction of the accommodating chamber, thereby forming a double-sided fixation for the glass slide.

[0031] In some embodiments, the surface of the base away from the fixing member is used as the top surface of the slide fixing device, and the hollow structure is curved or inclined toward the top surface to avoid the eyepiece.

[0032] Compared with the prior art, the slide fixing device provided by the utility model has the following beneficial effects:

[0033] 1. The utility model provides a glass slide fixing device, which synchronously adjusts the pressing or loosening of the fixing member on the glass slide by the squeezing condition of the glass slide on the adjusting part, thereby realizing rapid assembly and disassembly and ensuring the consistency of the position of the glass slide each time it is fixed.

[0034] 2. The utility model provides a glass slide fixing device, in which an elastic component is connected to the fixing part, and the elastic component can provide elastic force for the movement of the fixing part, thereby ensuring that the adjustment part can shrink inward when under pressure to provide a storage position for the glass slide. When the glass slide is pulled out, the elastic component drives the adjustment part to reset, so that the device can return to its initial state.

[0035] 3. The glass slide fixing device provided by the utility model is provided with an auxiliary fixing member that can be displaced through manual operation of an operator, thereby achieving more precise adjustment of the fixation of the glass slide and being able to produce more diversified operations for different working conditions.

DETAILED DESCRIPTION

[0043] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0044] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0045] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0046] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0047] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0048] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0049] In one embodiment, the reference specification Figure 1A glass slide fixing device provided by the utility model is described. The glass slide fixing device provided by the utility model can realize the rapid installation and removal of the glass slide. The operation steps are very simple and easy to use. At the same time, the glass slide will not be offset during the installation and removal process.

[0050] Reference Manual Attached Figures 1 to 3 The utility model provides a glass slide fixing device, including a base 1 and a fixing member 2. The base 1 is provided with a accommodating chamber 10 adapted for the glass slide, at least a portion of the accommodating chamber 10 is a hollow structure for preventing at least a portion of the glass slide from being blocked, and the fixing member 2 is rotatably connected to the base 1.

[0051] Specifically, the fixing member 2 and the accommodating chamber 10 are arranged opposite to each other with a preset gap therebetween for accommodating the glass slide, and the fixing member 2 has an adjusting portion 21 so that the glass slide can be operated to switch between the first state and the second state.

[0052] In the first state, the glass slide is inserted into the preset gap and the adjusting portion 21 is pressed, so that the fixing member 2 rotates in the first movement direction to compress the glass slide; in the second state, the glass slide escapes from the preset gap, the adjusting portion 21 is not pressed, so that the fixing member 2 rotates in the second movement direction to remove the glass slide.

[0053] It is worth mentioning that the pressing or loosening of the fixing member 2 on the glass slide is synchronously adjusted by the squeezing of the glass slide on the adjusting portion 21, which can ensure the consistency of the position of the glass slide each time it is fixed. Moreover, this setting realizes the rapid assembly and disassembly of the glass slide, which has excellent practicality.

[0054] Meanwhile, the profile and shape of the fixing member 2 are not specifically limited in this embodiment, and may be a straight line or a curved line, such as an inverted U shape, etc., and may be selected and reasonably replaced as long as it does not affect the technical effect of this embodiment.

[0055] Optionally, there are two fixing members 2, and the two fixing members 2 are symmetrically distributed along the length direction of the accommodating chamber 10, so as to form double-sided fixation for the slide glass.

[0056] It should be noted that although the accompanying drawings only show the implementation form of two fixing parts 2, it does not mean that the operator cannot set other numbers of fixing parts 2. If the designer improves or adjusts the specific shape, quantity, etc. of the fixing parts 2 based on the technical concept of the present invention, it should also be included in the protection scope of the present invention.

[0057] Furthermore, the accommodating chamber 10 has an insertion side and an abutting side 101 .

[0058] Among them, one side wall of the accommodating chamber 10 passes through the corresponding edge of the base 1 to form an insertion side of the accommodating chamber 10 . The insertion side and the abutting side 101 are arranged oppositely, and the adjusting portion 21 is located at the end of the fixing member 2 close to the abutting side 101 .

[0059] It can be understood that the two opposite sides of the accommodating chamber 10 are respectively set as the insertion side and the abutment side 101. Therefore, when installing and removing the slide, the operator can insert or pull out the slide at the insertion side. During the process, the slide can slide along the accommodating chamber 10, ensuring the reliability of the slide during movement.

[0060] Furthermore, the opening of the insertion side of the accommodating chamber 10 has a chamfered design, which expands the range of the opening, thereby preventing collision when inserting the slide.

[0061] In one embodiment, based on the above embodiment, the fixing member 2 is connected to the base 1 through the rotating member 3, and the relative position of the rotating member 3 is located between the insertion side and the abutment side 101, so that when the slide is switched between the first state and the second state, the fixing member 2 synchronously rotates in a clockwise or counterclockwise direction.

[0062] The fixing member 2 is connected to the base 1 via the rotating member 3, so that when the glass slide presses the adjusting portion 21, the fixing member 2 rotates accordingly to press the glass slide to achieve fixation.

[0063] Please refer to the attached Figure 2 The base 1 has a boss 11 , so that the rotating member 3 is connected to the boss 11 correspondingly, thereby improving the stability and reliability of the rotating member 3 .

[0064] In addition, the first movement direction and the second movement direction are mentioned above, which can be understood through the drawings and related contents. Since the fixing member 2 is rotatably connected to the base 1, it can be understood that the first movement direction and the second movement direction are clockwise or counterclockwise respectively.

[0065] Please refer to the attached Figure 2 The movement of the fixing part 2 on the left side, when the glass slide is inserted into the gap, the glass slide will gradually extend inward along the accommodating chamber 10, and then squeeze the adjusting part 21, so that the end of the fixing part 2 with the adjusting part 21 moves upward, and the end of the fixing part 2 away from the adjusting part 21 moves downward, thereby simultaneously pressing the glass slide. The upward movement of one end of the fixing part 2 and the downward movement of the other end correspond to the counterclockwise direction of the fixing part 2, and the first movement direction is the counterclockwise direction.

[0066] Similarly, when the glass slide is withdrawn from the gap, the second movement direction is clockwise; of course, in other embodiments, depending on the viewing angle and reference object, clockwise or counterclockwise is uncertain, and this is only for the case of the attached figure.

[0067] In another embodiment, if Figure 2 As shown, the fixing member 2 is movably connected to an auxiliary fixing member 41 .

[0068] The auxiliary fixing member 41 faces the accommodating chamber 10 and can be operatively displaced toward or away from the accommodating chamber 10 , thereby adjusting the relative distance between the end of the auxiliary fixing member 41 and the accommodating chamber 10 .

[0069] It should be noted that the fixing member 2 also has an assembly hole that matches with the auxiliary fixing member 41 , and the auxiliary fixing member 41 is inserted into the assembly hole.

[0070] According to the above content, through manual operation of the operator, the auxiliary fixing member 41 can be displaced relative to the assembly hole. During this process, the auxiliary fixing member 41 is close to or away from the glass slide, thereby achieving more precise adjustment of the fixation of the glass slide and being able to produce more diversified operations for different working conditions.

[0071] Of course, the simplest connection between the auxiliary fixing member 41 and the fixing member 2 may be a threaded connection, so that the operator can tighten or loosen the slide glass by screwing the auxiliary fixing member 41. In other embodiments, there are other connection methods, which will not be described one by one here.

[0072] In one embodiment, Figure 3 As shown, the fixing member 2 is also provided with a locking member 42 that matches with the auxiliary fixing member 41 , a positioning groove is provided on the outer periphery of the auxiliary fixing member 41 , and the locking member 42 passes through the fixing member 2 .

[0073] In the first state, the locking member 42 moves toward the direction approaching the auxiliary fixing member 41 to be engaged with the positioning groove, thereby limiting the auxiliary fixing member 41; in the second state, the locking member 42 moves toward the direction away from the auxiliary fixing member 41 to disengage the locking member 42 from the positioning groove, thereby unlocking the auxiliary fixing member 41.

[0074] It should be noted that when the outer periphery of the auxiliary fixing member 41 is a smooth surface, one or more positioning grooves are set on the smooth surface, and the auxiliary fixing member 41 is limited by a locking member 42. The locking member 42 can play the role of a latch, and after being inserted into the positioning groove, it can prevent the auxiliary fixing member 41 from rotating circumferentially or shifting in the vertical direction, thereby avoiding crushing the slide and preventing the auxiliary fixing member 41 from accidentally falling off.

[0075] Another point to note is that when the device is provided with an auxiliary fixing member 41, the slide is pressed by the auxiliary fixing member 41, and the fixing member 2 plays the role of driving the movement of the auxiliary fixing member 41; in addition, if there is no need to perform controllable operations such as limiting the auxiliary fixing member 41, the fixing member 2 and the auxiliary fixing member 41 can also be fixed together to form a whole pressure rod structure. This embodiment only proposes an implementation situation, and it can be changed or adjusted accordingly in actual application.

[0076] In one embodiment, Figure 2 As shown, the surface of the adjusting portion 21 close to the accommodating chamber 10 is configured as an inclined end surface 210, and the inclined end surface 210 faces away from the abutting side 101 of the accommodating chamber 10, which is suitable for guiding the displacement of the slide.

[0077] It can be understood that the inclined end surface 210 makes the distance between the adjusting portion 21 and the accommodating chamber 10 present a monotonically increasing form (defined according to the insertion direction of the glass slide), which can provide guidance for the insertion or removal of the glass slide, so that when the glass slide squeezes the adjusting portion 21, it can be pushed to the abutting side 101 along the trajectory of the inclined end surface 210. Since the distance between the adjusting portion 21 and the accommodating chamber 10 is the smallest here, the glass slide pushes the adjusting portion 21 upward, causing the fixing part 2 to rotate, thereby completing the fixation of the glass slide, and the glass slide installation process is very smooth.

[0078] Similarly, when the glass slide is to be removed, the operator pulls the glass slide outward, and the distance between the adjustment portion 21 and the accommodating chamber 10 becomes larger and larger, so that the glass slide cannot squeeze the adjustment portion 21, and the fixing member 2 releases the glass slide so that it can be removed.

[0079] Furthermore, according to the contents of the above-mentioned embodiment, an interlocking structure can also be provided between the fixing member 2 and the base 1. During the process of installing or removing the glass slide, the interlocking structure is opened to enable the fixing member 2 to move and rotate. When the glass slide has been pushed into place, the interlocking structure is fastened to prevent the fixing member 2 from moving and rotating.

[0080] It should be noted that many interlocking structures have been disclosed in the prior art, such as a combination of buckles and slots. These combinations can be applied to the relevant structures of the present invention as long as they do not affect the technical effects of the present invention.

[0081] In one embodiment, an elastic component is provided between the adjusting portion 21 and the base 1. In a first state, the elastic component is compressed, thereby driving the adjusting portion 21 to move away from the accommodating chamber 10. In a second state, the elastic component is not compressed, thereby driving the adjusting portion 21 to reset.

[0082] In this embodiment, the elastic component provided can provide elastic force for the movement of the fixing member 2, ensuring that the adjusting portion 21 can contract inward when under pressure to provide a storage position for the glass slide. When the glass slide is pulled out, the elastic component drives the adjusting portion 21 to reset, so that the device can return to its initial state to cope with subsequent work.

[0083] Furthermore, the elastic component includes a spring 51 and a fixing bracket 52. The fixing bracket 52 is fixed to a side of the base 1 having the accommodating chamber 10. The adjusting portion 21 and the fixing bracket 52 are fixed by the spring 51, and the spring 51 is used to provide elastic force.

[0084] For details, please refer to the attached Figure 3 and Figure 4 The number of the fixing bracket 52 and the spring 51 are both two according to the number of the fixing parts 2, and they are respectively located on both sides of the accommodating chamber 10. Since the setting methods of the fixing brackets 52 and the springs 51 on both sides are the same, only one of them will be described later.

[0085] Referring to the accompanying drawings again, a receiving hole for loading the spring 51 is provided on the fixing member 2. The setting of the receiving hole can prevent the spring 51 from being exposed to the outside world, thereby avoiding the problem of the spring 51 being rusted or corroded; at the same time, the receiving hole can also limit the spring 51 to prevent the spring 51 from producing abnormal deformation during the stretching or compression process, and further drive the fixing member 2 to shift synchronously.

[0086] Refer to Figure 3 One section of the fixing bracket 52 is fixed on the base 1 , and the other end extends toward the accommodating chamber 10 to form a cantilevered portion 520 . The spring 51 is connected to the cantilevered portion 520 , and the cantilevered portion 520 is adapted to the width and size of the fixing member 2 .

[0087] In a natural state, the spring 51 is in a stretched state, so that the position of the adjusting part 21 is the lowest, that is, the distance from the accommodating chamber 10 is the smallest. After the adjusting part 21 is compressed, the spring 51 naturally contracts to drive the adjusting part 21 to move, which corresponds to the activity of the adjusting part 21 when the glass slide is installed in the above content; it can be understood that when the device does not have a glass slide installed, the adjusting part 21 is not compressed, and the spring 51 drives the adjusting part 21 to restore the initial state. Then, when the operator needs to install the glass slide later, he can directly operate without manually restoring the device.

[0088] Further, such as Figure 4 and Figure 5As shown, the surface of the base 1 away from the fixing part 2 is used as the top surface of the slide fixing device, and the hollow structure has an arc surface or a slope 6 facing the top surface to avoid the eyepiece. Only the setting of the slope 6 is shown in the accompanying drawings, but in other embodiments, the specific contour of this edge can be set according to the actual eyepiece contour.

[0089] At the same time, a detection module installation position 7 is also provided on the base 1. The detection module installation position 7 is located adjacent to the accommodating chamber 10. The detection module can be installed and the presence of the slide can be detected by the detection module, thereby reminding the operator of the installation status of the slide for timely processing.

[0090] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
