Description

Technical Field

[0001] This utility model belongs to the field of laser pen technology, specifically relating to a laser pen protective mechanism and a laser pen. Background Technology

[0002] A laser pointer is a handheld device that emits a laser beam. Inside a laser pointer is a laser generator, mainly consisting of a laser diode. When an appropriate current is applied to the laser diode, the electrons in the gain medium undergo electron transitions, causing them to release energy in the form of photons, which is then amplified and ultimately forms a highly concentrated, unidirectional laser beam that is emitted through a lens at the front.

[0003] Currently, most laser pointers on the market have replaceable lamp heads. The lamp head is detachably connected to the laser pointer body. After the laser beam is emitted, it forms different patterns and light spots of different sizes and shapes after passing through different lamp heads.

[0004] However, when changing the laser head of commercially available laser pointers, improper operation can easily lead to the laser shining directly into the eyes, causing damage to the operator's eyes. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a laser pointer protection mechanism and laser pointer to solve the problem that the laser pointer can easily shine directly into the eyes of the operator and cause injury when changing the lamp head.

[0006] On the one hand, the technical solution of this utility model to solve the above-mentioned technical problems is as follows: a laser pointer protection mechanism, comprising:

[0007] Mounting base, the mounting base is disposed at the emitting end of the laser pointer, the mounting base is hollow to form a receiving cavity, and the mounting base has an emitting hole that penetrates the receiving cavity along the emitting direction of the laser pointer;

[0008] At least one blocking element is movably connected in the receiving cavity for blocking or exposing the laser beam passing through the emission aperture.

[0009] Compared with existing technologies, the above technical solutions have the following beneficial effects:

[0010] By installing a mounting base at the laser pointer's emitting end, and placing a blocking component inside the accommodating cavity of the mounting base, the laser beam emitted from the laser pointer's emitting end can be emitted through the emitting hole in the mounting base. At the same time, the blocking component, which is movable in the accommodating cavity, can be moved into the emitting hole, blocking the laser beam emitted through the emitting hole, thus achieving a shielding effect and preventing the laser from shining directly into the eyes and causing damage when the laser pointer's head is removed for replacement.

[0011] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0012] In one embodiment, a guide groove is provided at the top or bottom of the accommodating cavity, pointing towards the emission hole, and the blocking member is slidably connected in the guide groove.

[0013] By setting a guide groove, the blocking component can be guided more accurately and quickly through the guide groove into the emission hole to block the emission path of the laser beam, thereby preventing the laser from emitting and injuring the eyes.

[0014] In one embodiment, the accommodating cavity is provided with a reset member corresponding to each of the blocking members, and the reset member is used to push the blocking member toward the emission hole.

[0015] By setting a reset component, the blocking component can be automatically pushed towards the center of the emission hole. When there are no other components in the emission hole, the blocking component can immediately extend into it to block the laser beam, ensuring that there is always an object in the emission hole to block the laser beam.

[0016] In one embodiment, the reset member is an elastic body disposed in the guide groove, and the reset member is located at the end of the blocking member away from the emission hole.

[0017] In one embodiment, the reset element is a pair of magnets embedded in the blocking element and the mounting base, the pair of magnets having the same polarity, used to push the blocking element toward the emission hole.

[0018] In one embodiment, at least two blocking members are evenly spaced around the emission hole, and a tapered abutment is formed at the end of the blocking member near the emission hole, so that the abutment portions can fit tightly together circumferentially when they come into contact.

[0019] By arranging multiple blocking components evenly spaced circumferentially, when the multiple blocking components retract inward, they can be used to clamp other components located in the emission hole, such as the laser head; at the same time, the end of the blocking component near the center is set as a conical abutment part, which ensures that when multiple blocking components gather towards the center, this end can fit tightly and block the laser beam passing through the emission hole.

[0020] In one embodiment, the mounting base includes two bodies rotatably connected to each other, forming the receiving cavity between the two bodies. Each of the two bodies has a plurality of corresponding rotating grooves and guide grooves on one side facing the receiving cavity. One end of the rotating groove is inclined toward the emission hole, and the blocking member is provided with a limiting part that matches and extends into the rotating groove.

[0021] In one embodiment, at least one of the bases is provided with anti-slip texture on its outer periphery.

[0022] On the other hand, this embodiment also discloses a laser pointer, which includes the laser pointer protection mechanism described above.

[0023] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0024] 1. The blocking component connected to the accommodating cavity in the mounting base can block the emission port or move away from the emission port. When blocking, it blocks the emission of the laser beam to avoid injury to the eyes of personnel. When the blocking component does not block, the laser is emitted normally.

[0025] 2. By setting guide grooves, the blocking component can be inserted into the firing hole more accurately and quickly for shielding.

[0026] 3. With the reset component, after the lamp head is removed from the emission hole, the blocking component can be pushed immediately to insert the shielding component into the emission hole for shielding.

[0027] 4. By utilizing the cooperation of the guide groove and the rotating groove, when the seat body is rotated relative to each other, the inclined rotating groove drives the limiting part, which in turn drives the blocking part to move back and forth along the guide groove, thus enabling the blocking part to be opened quickly and manually.

[0039] Example 1

[0040] like Figure 1-2 As shown, the laser pointer protection mechanism provided by this utility model includes: a mounting base 1 and at least one blocking member 4.

[0041] Mounting base 1 is disposed on the emitting end of the laser pointer. The outer contour of mounting base 1 matches the outer periphery of the laser pointer. The interior of mounting base 1 is hollow and forms a receiving cavity 2. The emission direction of the laser pointer is consistent with the axis of the laser pointer. Mounting base 1 has an emission hole 3 that penetrates the receiving cavity 2 along the emission direction of the laser pointer. The emission hole 3 is located at the center of mounting base 1, and the aperture of emission hole 3 is larger than the outer contour of the laser beam. A blocking member 4 is movably connected in the receiving cavity 2 to block the laser beam from the emission hole 3.

[0042] like Figure 2 As shown, in this embodiment, multiple blocking members 4 can also be used to block the laser beam in the emission hole 3. Specifically, the number of blocking members is not limited, as long as the blocking members can block the laser beam in the reflection hole 3.

[0043] By setting a mounting base 1 at the laser pointer's emitting end, and setting a blocking member 4 in the accommodating cavity 2 of the mounting base 1, the emitting hole 3 passes through the accommodating cavity 2 axially, making the emitting hole 3 connected to the accommodating cavity 2. The laser beam emitted from the laser pointer's emitting end can be emitted through the emitting hole 3 in the mounting base 1. At the same time, the blocking member 4, which is movably set in the accommodating cavity 2, can be moved into the emitting hole 3, blocking the laser beam emitted through the emitting hole 3, thereby achieving a shielding effect and avoiding the problem of the laser shining directly into the eyes and causing damage when the laser pointer's lamp head 9 is removed for replacement.

[0044] In this embodiment, the top or bottom of the accommodating cavity 2 is provided with a guide groove pointing to the emission hole 3. The blocking member 4 is slidably connected in the guide groove. Correspondingly, the number of guide grooves is the same as the number of blocking members 4. The blocking members 4 slide in the guide groove. When blocking is required, the blocking member 4 slides along the guide groove and extends into the central emission hole 3 to block the laser beam. When blocking is not required, the blocking member 4 slides outward along the guide groove and returns to the accommodating cavity 2. By setting the guide groove, the blocking member 4 can be guided more accurately and quickly through the guide groove to extend into the emission hole 3 and block the emission path of the laser beam, thereby preventing the laser from emitting and injuring the eyes.

[0045] At least two blocking members 4 are evenly spaced around the circumference of the emission hole 3. At least two blocking members 4 are required to clamp the lamp head 9 and other components in the emission hole 3. In this embodiment, three blocking members 4 are provided, evenly spaced around the circumference. Each blocking member has a conical abutment portion 11 formed near the emission hole, allowing for tight circumferential contact when the abutment portions come into contact. When the three blocking members 4 are close to the emission hole 3, they can fit tightly together without any circumferential gaps. The conical abutment portions 11 at the three ends equally divide the plane of the emission hole. This is achieved by setting the ends of the blocking members 4 near the emission hole 3 to be conical and equally spaced. Figure 2 As shown, each blocking member 4 has a 120° sharp angle at this end, so that when the blocking member 4 comes into contact with the inward contact, it can fit tightly. If there are four blocking members 4, the conical contact part of each blocking member 4 near the emission hole 3 forms a 90° sharp angle, and so on.

[0046] By arranging multiple blocking members 4 evenly spaced around the perimeter, when the multiple blocking members 4 retract inward, they can be used to clamp other components located in the emission hole 3, such as the laser head 9; at the same time, the end of the blocking member 4 near the center is set to be circumferentially divided equally, so that when the multiple blocking members 4 gather towards the center, they fit tightly together and block the laser beam passing through the emission hole 3.

[0047] In this embodiment, the blocking element 4 is strip-shaped, and its specific width is not limited to that shown in the figure. The width of the blocking element 4 can be set to different widths according to the thickness of the laser beam, so that it can completely block the laser beam when it is focused to the emission hole 3. That is, the strip-shaped blocking element 4 in the figure can be wider or thinner.

[0048] Meanwhile, the blocking member 4 can be fan-shaped, or even equally divided fan-shaped. When multiple blocking members 4 converge at the central emission hole 3, they can completely block the emission hole 3.

[0049] The specific shape of the blocking component 4 is not limited here, as long as it can block the laser beam.

[0050] In order to enable the blocking component 4 to quickly block the light head 9 and other components after they leave the emission hole 3, the accommodating cavity 2 is provided with a reset component 5 corresponding to the blocking component 4. The reset component 5 is used to push the blocking component 4 toward the emission hole 3.

[0051] By setting a reset component 5, the blocking component 4 is automatically pushed towards the center emission hole 3 by means of magnetic force and elasticity. When there are no other accessories in the emission hole 3, the blocking component 4 can immediately extend into it to block it, ensuring that there is always an object in the emission hole 3 to block the laser beam.

[0052] In one embodiment, the reset member 5 is an elastic body disposed in the guide groove. The elastic body can be implemented by springs or the like. The reset member 5 is located at the end of the blocking member 4 away from the emission hole 3. Three springs are arranged in three guide grooves. The two ends of the spring in each guide groove abut against the end of the blocking member 4 away from the emission hole 3 and the inner wall of the accommodating cavity 2, respectively, for quickly pushing the blocking member 4 along the guide groove toward the emission hole 3.

[0053] In another embodiment, the reset member 5 is a pair of magnets embedded in the blocking member 4 and the mounting base 1. Since the magnets are embedded, they are not shown in the figure. The pair of magnets have the same polarity. The magnetic force of the magnets pushes the blocking member 4 toward the emission hole 3. Specifically, the magnets are embedded in the blocking member 4. For each blocking member 4, a magnet with the same polarity is provided on the mounting base 1 on the periphery, which pushes the blocking block toward the center quickly.

[0054] like Figure 2As shown, to facilitate manual separation of the blocking member 4 to the outside and easy insertion of the lamp head 9 into the emission hole 3, the mounting base 1 includes two rotatably connected bodies 101. The two bodies 101 fit tightly together vertically and can rotate relative to each other circumferentially. The receiving cavity 2 is formed between the two bodies 101. Several corresponding rotating grooves 10 and guide grooves are respectively formed on the side of the two bodies 101 facing the receiving cavity 2. If the guide groove is located at the top of the receiving cavity 2, that is, at the bottom of the upper body 101, then the rotating groove 10 is located at the bottom of the receiving cavity 2, that is, at the top of the lower body 101. If the guide groove is located at the bottom of the receiving cavity 2, then the rotating groove 10 is correspondingly located at the top. In this embodiment, the receiving cavity 2 and the guide groove are formed at the bottom of the upper body 101. Figure 2 Not shown in the image.

[0055] Meanwhile, the rotating groove 10 is provided with corresponding guide grooves on the top and bottom. One end of each rotating groove 10 is inclined toward the emission hole 3. The blocking member is provided with a matching limiting part 6 that extends into the rotating groove 10, so that when the two bodies 101 rotate relative to each other, the limiting part 6 can drive the blocking member 4 to slide back and forth along the guide groove. When the operator manually rotates one of the bodies 101, the position of the blocking member 4 can be adjusted.

[0056] After the corresponding blocking member 4 is equipped with a reset member 5, the blocking member 4 can be opened by rotating the base 101 by a certain angle, so that the blocking member 4 can overcome the force of the reset member 5 pushing the blocking member 4 inward. This makes it easy to put the lamp head 9 and other components into the emission hole 3. After being released, the reset member 5 can automatically push the blocking member 4 inward to retract and hold the components in the emission hole 3.

[0057] To prevent slippage when holding and rotating the seat 101, at least one of the seat 101 is provided with anti-slip texture 7 on its outer periphery. By rotating the seat 101 with anti-slip texture 7, it is less likely to slip.

[0058] Example 2

[0059] like Figure 1 As shown, this embodiment discloses a laser pen, which includes a pen body 8 and a laser pen protection mechanism as described in Embodiment 1. The protection mechanism is installed on the emitting end of the pen body 8, and the laser beam generated by the laser generator at the emitting end is emitted from the emitting hole 3 in the protection mechanism.

[0060] It also includes a lamp head 9, which is detachably connected to the emission hole 3 and held in place by a blocking member 4.

[0061] Alternatively, a magnet may be installed in the mounting base 1 to attract the lamp holder 9.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
